tacrolimus and Hyperlipidemias

The study was designed to compare the outcomes of sirolimus (SRL) combined with tacrolimus (TAC) and mycophenolate mofetil (MMF) combined with TAC in kidney transplantation recipients.. A literature search of PubMed, Embase, and Web of Science was performed to identify relevant studies, and the last update was on February 1, 2018. All studies with appropriate data comparing the SRL group with the MMF group were included. SRL and MMF were used in sufficient doses. Relevant information was recorded and analyzed. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were used to assess the effects of SRL and MMF. Relevant outcomes, including delayed graft function, acute rejection, graft survival, seroma, anemia, lymphocele, and hyperlipidemia, were compared.. Ten studies with a total of 2357 patients (n = 1256 receiving SRL vs n = 1101 receiving MMF) were ultimately included. Our results indicated that the SRL group experienced a higher rate of hyperlipidemia (OR: 1.864; 95% CI, 1.494-2.325) and lymphocele (OR: 2.58; 95% CI, 1.49-4.47). However, no significant differences were detected regarding the rates of delayed graft function, acute rejection, graft survival, infectious complications, anemia, or seroma.. This meta-analysis suggested that SRL combined with TAC and MMF combined with TAC were equally safe and effective for the kidney transplantation recipients. However, the MMF group exhibited a marginally significant advantage of lower incidence of hyperlipidemia and lymphocele.

In the first five yr after liver transplant, approximately one in 10 pediatric recipients will develop NODAT. Factors associated with higher risk for NODAT have been difficult to identify due to lack of uniformity in reporting and data collection. Limited studies have reported higher risk in those who are at an older age at transplant, those with high-risk ethnic backgrounds, and in those with particular underlying conditions, such as CF and primary sclerosing cholangitis. Immunosuppressive medications, including tacrolimus, cyclosporine A, GC, and sirolimus, have been implicated as contributing to NODAT, to varying degrees. Identifying those at highest risk, appropriately screening, and diagnosing NODAT is critical to initiating timely treatment and avoiding potential complications. In the pediatric population, treatment is limited primarily to insulin, with some consideration for metformin. Children with NODAT should be monitored carefully for complications of DM, including microalbuminuria, hypertension, hyperlipidemia, and retinopathy.

The therapeutic success of renal transplantation has been largely attributable to the development of effective and balanced immunosuppressive treatment regimens. This study provides a meta-analysis of a series of randomized controlled trials that compared the effects of tacrolimus and cyclosporine on metabolic syndrome (MetS) and cardiovascular risk factors after renal transplantation.. We searched various electronic databases and bibliographies, including MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE, for relevant studies published prior to October 2012.. Our meta-analysis included five randomized controlled trials that examined a total of 923 patients. The tacrolimus group and the cyclosporine group exhibited no significant differences in MetS incidence after renal transplantation; risk ratio (RR): 1.06, 95% confidence interval (CI): 0.73-1.55, P = 0.76. Cyclosporine treatment was associated with a higher incidence of hyperlipidemia (RR: 0.50, 95% CI: 0.39-0.64, P < 0.01). Although there were no statistically significant differences, cyclosporine treatment was associated with a higher incidence of hypertension (RR: 0.91, 95% CI: 0.83-1.00, P = 0.06) after renal transplantation compared to tacrolimus treatment, and tacrolimus treatment was associated with a higher incidence of diabetes after renal transplantation (RR: 1.79, 95% CI: 0.98-3.27, P = 0.06) compared to cyclosporine treatment.. Compared to tacrolimus treatment, cyclosporine treatment was associated with a higher incidence of hyperlipidemia. Future large-scale studies are expected to be conducted to further confirm our findings.

The use of calcineurin inhibitors (CNIs; cyclosporine and tacrolimus) has dramatically increased medium-term life expectancy after heart transplantation but has had only limited impact on long-term outcomes for heart transplant recipients. The original oil-based formulation of cyclosporine has been superceded by a microemulsion formulation (Neoral), which has more predictable pharmacokinetics and allows more precise dose-tailoring. Cyclosporine microemulsion and tacrolimus (Prograf) have a similar efficacy in the prevention of acute rejection of heart transplants, but their use is accompanied by nephrotoxicity and by cardiovascular side effects. The efficacy of immunosuppression can be improved by adjunctive therapy, such as azathioprine, mycophenolate mofetil (MMF; Cellcept), corticosteroids, and induction therapy. One of the most important predictors of patient mortality at >5 years after heart transplantation is cardiac allograft vasculopathy (CAV)/late graft failure, which accounts for 31% of deaths. Neither cyclosporine nor tacrolimus have been shown to prevent the development of CAV. In terms of efficacy, MMF provides a modest advantage over azathioprine in preventing CAV, and the combination of cyclosporine plus MMF results in significantly lower mortality than cyclosporine plus azathioprine. Overall, CNIs have multiple cardiovascular side effects, such as hypertension, hyperlipidemia and new-onset diabetes after transplantation, although cyclosporine and tacrolimus have somewhat different cardiovascular side-effect profiles. The challenge in choosing the best immunosuppressive regimen is to balance efficacy and safety to optimize graft and patient survival over the course of many decades. Because cyclosporine and tacrolimus have similar efficacy against acute rejection the choice of CNI for heart transplant recipients should be based on the relative risk of cardiovascular and renal side effects.

Sirolimus is a potent immunosuppressive medication that acts by inhibiting T-cell proliferation. It has been used in kidney transplantation because of its lack of nephrotoxicity. It is now being investigated in liver transplantation, but there are concerns about safety and long-term side effects such as dyslipidaemia. Hypertriglyceridaemia is a common adverse event seen with sirolimus use, and often does not respond to dose reduction or anti-lipemic drugs.. We report six patients who have developed significant hyperlipidaemia while receiving sirolimus, in spite of therapeutic trough levels.. All six patients showed either resolution or improvement in lipid levels with discontinuation of sirolimus.

Cyclosporine microemulsion (CyA) and tacrolimus (Tac) are the principal immunosuppressants prescribed for adult and pediatric renal transplantation. In the majority of patients, these calcineurin inhibitors have been used in combination with other immunosuppressive drugs, such as azathioprine or mycophenolate mofetil (MMF). In this review we will address the question of what calcineurin inhibitor we should use in an individual pediatric renal transplant patient. Well-designed randomized studies in children showed no difference in short-term patient and graft survival with cyclosporine microemulsion and tacrolimus. However Tac is significantly more effective than CyA microemulsion in preventing acute rejection after renal transplantation in a pediatric population when used in conjunction with azathioprine and corticosteroids. This difference disappears when calcineurin inhibitors are used in combination with MMF as both Tac and CyA produce similar rejection rates and graft survival. However, Tac is associated with improved graft function at 1 and 2 yr post-transplant. Adverse events of hypomagnesaemia and diarrhea seem to be higher in Tac group whereas hypertrichosis, flu syndrome and gum hyperplasia occurs more frequently in the CyA group. The incidence of post-transplant diabetes mellitus was almost identical between Tac and CyA treated patients. The recommendation drawn from the available data is that both CyA and Tac can be used safely and effectively in children. However Tac may be preferable to CyA because of steroid sparing effect and less hirsutism. We recommend that cyclosporine should be chosen when patients experience Tac-related adverse events. Nevertheless, the best calcineurin inhibitor should be decided on individual patients according to variable risk factors, such as risk of rejection in sensitized patient or delayed graft function. The possibility of adverse events should also be considered.

Sirolimus therapy has been used in orthotopic liver transplant (OLT) recipients diagnosed with a variety of diseases; chronic graft rejection (CR), calcineurin associated renal toxicity, preemptive immune suppression, calcineurin related neurotoxicity, preemptive therapy in transplant recipients with history of hepatocellular carcinoma, and steroid resistant allograft rejection.. A search for the medical literature and experiences involving sirolimus was done.. Several animal and human reports evaluating the use sirolimus in liver transplant recipients are found and discussed.. Sirolimus has been used for multitude of indications, primarily based on anecdotal experiences. However, reports of sirolimus related side effects have decreased the transplant communities' enthusiasm towards promoting this agent as a safe immune suppression agent.

After transplantation, immunosuppressive drugs induce frequently lipid changes and glucose intolerance which result in worsening of the patient's prognosis. The mechanisms of the metabolic changes of corticosteroid hormones, cyclosporine, tacrolimus, sirolimus and mycophelonate are shortly reviewed but are not fully understood. Controlling serum lipids is critical in the management of the patients after transplantation. Statins seem to be the best choice but it remains some concerns about drug interactions and risk of rhabdomyolysis. Fibrates except gemfibrozil are not recommended because potential renal side effects.

Cardiovascular disease is one of the major causes of morbidity and mortality following solid organ transplantation. Many of the current immunosuppressive drugs are associated with an increase of one or more risk factors for the development of atherosclerosis. This review compares the mechanism by which individual immunosuppressive agents may impact on these risk factors and the differential contribution of cyclosporine, tacrolimus, mycophenolate, azathioprine, and Rapamycin to these individual risk factors. Attention to the potential cardiovascular toxicities of individual immunosuppressive agents may help design strategies for maintenance of immunosuppression tailored to individual patients.

In this review we examine the complex interactions between lipoprotein metabolism, immunosuppressive drug therapy, and inflammation and the potential benefits of lipid-lowering drug therapy after heart transplantation. The newer formulations of cyclosporine, Neoral (Novartis Pharmaceuticals; Basle, Switzerland), and other newer agents such as tacrolimus may have advantages in regard to lipid metabolism as compared with traditional triple-drug immunosuppression. Lipoprotein levels may influence both the toxicity and efficacy of cyclosporine. Dyslipidemia may adversely influence inflammation and rejection in the allograft. Two recent clinical trials have shown that lipid-lowering therapy with a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor alone or in combination with low-density lipoprotein apheresis may confer significant benefits toward preventing transplant coronary artery disease.

The correction of post-transplant hyperlipidaemia warrants the judicious and timely use of pharmacological agents with dietary modification and exercise. Reduction in hyperlipidaemia may have some role in decreasing the incidence of chronic rejection of allografts. The awareness that the morbidity and mortality of atherosclerotic disease may be lowered by active intervention will result in a better quality of life for transplant recipients.

Following heart transplantation (HT), HMG CoA reductase inhibitors (statins) have been shown to reduce total and low-density lipoprotein (LDL) cholesterol, development of cardiac allograft vasculopathy (CAV), and mortality. Studies in HT patients have demonstrated the safety of low/moderate intensity statins; however, little data exist using high-intensity (HI) statins. The study aim was to evaluate the safety and efficacy of HI statins in HT recipients receiving tacrolimus.. This single-center, retrospective analysis included adult HT recipients from January 1, 2005, to December 31, 2015, who received HI statin therapy during posttransplant follow-up. The primary outcome, tolerability, was defined as the absence of myalgias, hepatotoxicity, rhabdomyolysis, or HI statin dose reduction/discontinuation. The secondary end point was the mean reduction in total and LDL cholesterol.. Among the 24 patients included, one experienced myalgias and therapy discontinuation (4%; P > 0.99). No other HI statin dose reduction/discontinuation occurred, and no instances of rhabdomyolysis or hepatotoxicity were observed. The average reduction in total and LDL cholesterol after conversion to HI statin was 35 mg/dL (P = 0.02) and 19 mg/dL (P = 0.10), respectively.. High-intensity statin therapy appears safe and efficacious in HT recipients receiving tacrolimus and is a reasonable option for the treatment of refractory hyperlipidemia.

The metabolic syndrome (MS) is an important risk factor for graft dysfunction and patient death after renal transplantation. The aim of this sub-analysis of the Symphony study was to assess the progression of the laboratory parameters associated with MS in the first year after transplantation.. Data collected from the Symphony study were used; 1645 patients were randomized to receive standard-dose cyclosporine (Stand-CsA), low-dose cyclosporine (Low-CsA), tacrolimus (Low-Tac) or sirolimus (Low-SRL), in addition to mycophenolate mofetil (MMF) and corticosteroids. Data were collected for levels and progression over the first year post-transplantation of systolic and diastolic blood pressure, uric acid, triglycerides, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and fasting glucose levels by treatment arm.. The low-SRL group had significantly higher levels of triglycerides and LDL. The two CsA arms were associated with the highest uric acid levels at each time point. There were no significant differences in overall levels or changes in glucose or HDL. Patients in the standard-CsA arm had significantly higher diastolic blood pressure than those in the Low-SRL and Low-Tac arms. Systolic blood pressure was higher in the Low-CsA arm than in the Low-Tac arm. The use of antihypertensive and antidiabetic agents was similar between the treatment arms. In the Low-SRL arm, more patients were treated with lipid-lowering therapy. Mean daily steroid doses were the highest in the Low-SRL arm.. This sub-analysis demonstrates that there is a difference in metabolic parameters between immunosuppressive groups. CsA therapy was associated with the highest values of uric acid and systolic and diastolic blood pressure. Patients on SRL therapy had the worst lipaemic control. A possible effect of Tac on new-onset diabetes could not be excluded.

This 24-week, open, single-arm, prospective, multicenter study evaluated the effects of conversion from ciclosporin to Tacrolimus QD in adult kidney transplant patients. Stable patients receiving ciclosporin were converted to Tacrolimus QD at 0.1mg/kg/day. Relative change in renal function (primary endpoint) was assessed using estimated creatinine clearance (eCrCl) with a noninferiority margin set at -10%. A total of 346 patients were enrolled; and 301 patients were treated per protocol (PPS) in the hyperlipidemia (n=42), hypertrichosis (n=106), hypertension (n=77) and gingival hyperplasia (n=76) groups. Relative change in eCrCl was -0.6% in all PPS patients (95% CI, -2.2; 0.9) and -5.3% in the hyperlipidemia (CI, -9.59; -0.97), 0.9% in the hypertrichosis (CI, -2.59; 4.45), -0.1% in the hypertension (CI, -3.8; 3.68), and -1% in the gingival hyperplasia groups (CI, -4.63; 2.65) (PPS), meeting noninferiority criteria. There was no acute rejection. Decreases in serum lipids and blood pressure were moderate but without meaningful change in the number of treatment medications. Substantial decreases in severity of ciclosporin-related cosmetic side effects were evident from investigator and patient self-report of symptoms. Renal function remained stable after conversion to Tacrolimus QD. The effect of conversion on cardiovascular parameters was not clinically meaningful, however, marked improvement in ciclosporin-related cosmetic side effects was observed.

Steroids have had the main role in renal transplant for more than 4 decades. However, chronic use of steroids is associated with many comorbidities, owing to a lack of assessing cost-benefit of steroid avoidance in live-donor renal allotransplants. In this prospective, randomized, controlled study, we aimed to assess the cost-benefit of a steroid-free immunosuppression regimen among Egyptian live-donor renal transplants.. One hundred patients were randomly allocated to receive tacrolimus, mycophenolate mofetil, and steroids for only 3 days (n=50 patients; study group) or tacrolimus, mycophenolate mofetil, and steroids on a maintenance basis (n=50 patients; control group). All patients received basiliximab (Simulect) induction, with median follow-up of 12 months.. Both groups showed comparable graft and patient survivals, rejection episodes, and graft functioning. Posttransplant comorbidities were significantly more prevalent in the steroid-maintenance group. Hypertension was detected in 4% of steroid-free group versus 24% in the steroid-maintenance group (P = .0009). Posttransplant diabetes mellitus, serious infections, and hyperlipidemia were significantly more prevalent in the steroid-maintenance group (P < .05). Associated hospitalization costs were 2.2-fold higher in the steroid-maintenance group than they were in the steroid-free group. One year after transplant, the cost of managing posttransplant comorbidities was significantly higher in steroid-maintenance group, despite comparable costs of immunosuppression.. In low, immunologic risk recipients of live-donor renal transplants, using basiliximab induction and maintenance with tacrolimus, mycophenolate mofetil, steroid avoidance was associated with lower first annual total costs despite comparable immunosuppression costs, which was attributed to lower costs of associated morbidities.

In an open, prospective, multicenter study, stable renal graft recipients were converted to tacrolimus because of cyclosporine-related side effects. Seventy-five patients were switched primarily because of hyperlipidemia. After the switch to tacrolimus, mean total cholesterol was reduced by 15% at month 6. One hundred seventy-seven additional patients were switched primarily for other indications: hypertrichosis, gingival hyperplasia, and arterial hypertension, and these symptoms also improved after the switch. In this analysis, serum lipid levels were categorized according to a modified standard classification of lipid parameters for renal transplant patients (published by the NKF Work Group). The aim was to estimate the proportion of patients reaching normal lipid levels after the conversion to tacrolimus therapy. In patients with primary indication hyperlipidemia, the proportion with normal cholesterol levels increased significantly from 5.6% at baseline to 37.5% at month 6 (P < .05). For LDL cholesterol, the increase was from 54.1% at baseline to 64.9% at month 6, and for triglycerides the improvement was from 25.4% to 33.8%. HDL cholesterol levels remained stable. Similar changes of lipid parameters were also observed in the subgroups of patients converted to tacrolimus primarily because of other indications. After conversion from cyclosporine to tacrolimus, a significantly higher proportion of stable renal graft recipients reached normal total cholesterol levels. For LDL cholesterol and triglycerides, a trend for normalization was observed. Thus, the improvement of serum lipid levels resulted for many patients in a change to a better level class and improved or normalized their cardiovascular risk parameters.

Cardiovascular disease is the leading cause of death in renal transplant recipients. Arterial wall properties are surrogate markers for arteriosclerosis. Previous investigations have shown that the cardiovascular risk profile is better with tacrolimus compared to cyclosporine. Renal function, blood pressure, and lipid levels improve. The hypothesis is that arterial wall properties will improve after conversion from cyclosporine to tacrolimus. Thirty-four stable renal recipients were converted from cyclosporine microemulsion to tacrolimus without changing concomitant medication. Before and after conversion we performed wall track ultrasounds of the carotid and the brachial arteries; pulse wave velocity (PWV); laboratory investigations; 24-hour ABPM; estimates of renal function; and Framingham risk scores. After conversion the 24-hour ambulatory blood pressure monitoring (ABPM) did not change. Total cholesterol, LDL cholesterol, and triglycerides improved significantly. Renal function (Cockroft) improved. There were no significant changes in arterial wall properties, or in PWV. Framingham comparative risk scores improved only significantly in patients not receiving statins. In conclusion, 3 months after conversion from cyclosporine to tacrolimus total cholesterol, LDL cholesterol, and triglycerides were significantly decreased and renal function significantly improved. Contrary to expectation, ABPM did not change, probably due to prolonged use (>10 years) of cyclosporine. There was also no difference in arterial wall properties.

The hyperlipidemic and hypertensive effects of ciclosporin constitute a cardiovascular risk. Cosmetic side-effects are known to reduce patients' quality of life. This was a 6-month, open, prospective, multicentre study in 296 adult kidney transplant patients to evaluate the conversion from ciclosporin to a tacrolimus-based regimen. Primary indications for conversion were hyperlipidemia (n =77), hypertension (n = 72), hypertrichosis (n = 32) and gingival hyperplasia (n = 115). At month 6, hyperlipidemia and hypertension were at least moderately improved in 59.1% and 63.5% of patients, and strongly or completely resolved in 29% and 25%. Gingival hyperplasia and hypertrichosis were strongly or completely resolved in 73% and 72% of patients. Mean total cholesterol was reduced from 255 to 218 mg/dl. Mean systolic blood pressure (SBP) was reduced from 152.9 to 137.5 mmHg and mean diastolic blood pressure (DBP) from 90.7 to 85.8 mmHg. Ciclosporin-related side-effects resolved or improved after conversion to tacrolimus.

Tacrolimus improves lipid profile in renal and liver transplant recipients. The impact of conversion from cyclosporine microemulsion (Neoral) to tacrolimus (Prograf) in a large randomized study of stable heart transplant recipients with treated but persistent mild dyslipidemia is reported.. One hundred twenty-nine long-term (>or=12 months) cyclosporine microemulsion-treated heart transplant recipients with low-density lipoprotein cholesterol >2.5 mmol/liter and/or a total cholesterol/high-density lipoprotein cholesterol ratio >4 were recruited for the study. Complete lipid profile was assessed before (baseline) and after 6 months of treatment with either cyclosporine microemulsion maintenance (n=64) or tacrolimus conversion (n=65).. At 6 months, tacrolimus-converted patients exhibited a greater decrease in total cholesterol (from 5.51 +/- 0.16 to 4.88 +/- 1.22 mmol/liter [tacrolimus], vs 5.61 +/- 1.36 to 5.38 +/- 0.87 mmol/liter [cyclosporine]; p = 0.0078). This decrease in cholesterol was caused largely by a decrease in low-density lipoprotein cholesterol (-0.41 +/- 0.54 [tacrolimus] vs -0.13 +/- 0.55 [cyclosporine]; p=0.0018). There were no changes in high-density lipoprotein cholesterol and triglyceride levels, but apolipoprotein B therapy was reduced in tacrolimus-converted vs cyclosporine-maintained patients (p=0.0003). By 6 months, 23.7% of tacrolimus- vs 6.7% of cyclosporine-treated patients met the target lipid levels for high-risk patients (p=0.0094). Conversion from cyclosporine to tacrolimus resulted in decreases in blood urea nitrogen, creatinine, and uric acid without any changes in glucose, HbA(1C), and insulin levels.. Conversion from cyclosporine microemulsion- to tacrolimus-based immunoprophylaxis resulted in decreased cholesterol, apolipoprotein B, urea, creatinine, and uric acid without any clinically evident perturbation of glucose metabolism in stable heart transplant recipients with treated but persistent mild dyslipidemia.

Chronic graft-versus-host disease (cGVHD) remains a major cause of morbidity and mortality in haematopoietic transplant recipients. Sirolimus is a macrocyclic triene antibiotic with immunosuppressive, antifungal and antitumour properties, that has activity in the prevention and treatment of acute GVHD. We conducted a phase II trial of sirolimus combined with tacrolimus and methylprednisolone in patients with steroid-resistant cGVHD. Thirty-five patients who developed GVHD after day 100 post-transplant were studied. Six patients had a complete response and 16 a partial response with an overall response rate of 63%. Major adverse events related to the combination of tacrolimus and sirolimus were hyperlipidaemia, renal dysfunction and cytopenias. Four patients had thrombotic microangiopathy (TMA) and 27 (77%) had infectious complications. The median survival for the whole group was 15 months. A significantly better outcome was observed in patients with a platelet count > or = 100 x 10(9)/l, as well as in those with true chronic manifestations of GVHD compared to those with acute GVHD beyond day 100. Controlled trials comparing this approach with alternative strategies to determine which can best achieve the goal of GVHD-free survival are warranted.

Hyperlipidemia is frequently developed following renal transplantation and results in worsening of the patient's prognosis.. In this study, 14 patients who had hypercholesterolemia [total cholesterol (TC) >200 mg/dL] and hypertriglyceridemia [triglyceride (TG) >150 mg/dL] 1 month after renal transplantation (post-transplantation), seven patients each under the treatment with immunosuppressant, either cyclosporine or tacrolimus started simvastatin treatment of 5-10 mg/d and continued the treatment for 4 yr. The effect of simvastatin treatment was assessed by comparison in serum lipid levels (TC, TG, cholesterol in lipoprotein fractions, and apolipoproteins) and the lipid metabolism related enzyme activities for post-transplantation, after 6-month and 4-yr simvastatin treatment.. Simvastatin treatment of 4 yr significantly decreased the elevated levels of serum TC from 234.5 +/- 30.8 to 186.3 +/- 20.5 mg/dL (p < 0.001), low density lipoprotein cholesterol (LDL-C) from 116.7 +/- 22.5 to 82.7 +/- 16.6 mg/dL (p < 0.05) and TG from 200.3 +/- 109.2 to 97.0 +/- 45.2 mg/dL (p < 0.001). In addition, there were significant decreases in elevated serum very-low-density lipoprotein cholesterol (VLDL-C) from 47.8 +/- 18.4 to 28.6 +/- 9.5 mg/dL (p < 0.001) and LDL2 cholesterol (LDL2-C) from 20.8 +/- 8.2 to 5.7 +/- 1.8 mg/dL (p < 0.001).. The results indicate that 4-yr treatment of simvastatin improves profiles of the atherogenic lipids in renal transplant patients with immunosuppressant caused hypercholesterolemia and hypertriglyceridemia treated either cyclosporine or tacrolimus in similar manner.

The aim of this single-center study was to investigate whether trough level adjusted mycophenolate mofetil (MMF) is more efficacious in combination with tacrolimus (TAC) or cyclosporine (CsA) and to evaluate the impact of either drug on MMF dosage.. Sixty patients (TAC, n = 30; CsA, n = 30) undergoing heart transplantation were randomized into a prospective, open-label, controlled trial. Immunosuppression consisted of TAC or CsA in combination with MMF and corticosteroids. Target blood trough levels of TAC, CsA, and mycophenolic acid (MPA) were in the range of 10 to 15 ng/mL, 100 to 300 ng/mL, and 1.5 to 4.0 microg/mL, respectively. Acute rejection episodes (ARE); survival data; and adverse events with a special emphasis on infections, diabetes, hypertension, hypercholesterolemia, and the development of graft vessel disease (GVD) were recorded.. Baseline characteristics were well balanced. All patients were successfully withdrawn from corticosteroids within 6 months of transplant. Freedom from acute rejection was significantly higher (P = 0.0001) and the incidence of ARE per 100 patient days significantly lower in the TAC-MMF group than in the CsA-MMF group (0.03 vs. 0.15; P = 0.00007). Overall patient survival during follow-up was similar (93% vs. 90%). To achieve the targeted MPA blood levels, a significantly lower dose of MMF was required for TAC versus CsA patients. After a follow-up time of 2 years, the mean GVD score was 1.85 +/- 3.18 in the TAC-MMF group and 3.95 +/- 4.8 in the CsA-MMF group (P = 0.08).. At the selected doses and target levels for TAC and CsA used in this study, trough level adjusted MMF was more efficacious in combination with TAC for prevention of ARE. Furthermore, CsA patients need significantly more MMF to achieve similar MPA levels.

This is the first report of a randomized, multicenter, clinical trial comparing the combination of sirolimus or mycophenolate mofetil (MMF) with tacrolimus-based immunosuppression in kidney transplantation. Results at 6 months of follow-up are presented.. Before transplantation, patients were randomized to receive tacrolimus plus corticosteroids with sirolimus (n=185) or MMF (n=176). The primary endpoint of the study was the incidence of biopsy-confirmed acute rejection. Patient and graft survival, renal function, and composite endpoints also were evaluated. Safety was assessed by monitoring laboratory parameters and adverse events.. By 6 months of follow-up, the incidence of biopsy-confirmed acute rejection was similar in both treatment groups (13.0% tacrolimus+sirolimus vs. 11.4% tacrolimus+MMF; P=0.64 log-rank). Patient survival (97.3% tacrolimus+sirolimus vs. 97.7% tacrolimus+MMF) and graft survival (93.0% tacrolimus+sirolimus vs. 95.5% tacrolimus+MMF) were equivalent (P=0.53, overall survival log-rank). There was a significantly higher incidence of study drug discontinuation in patients receiving sirolimus (21.1% vs. 10.8%; P=0.008). Renal function was significantly better in the MMF-treatment group (serum creatinine 1.44+/-0.45 mg/dL vs. 1.77+/-1.42 mg/dL; P=0.018). Hyperlipidemia was significantly more prevalent in the sirolimus-treatment group. Diastolic blood pressure was significantly higher in sirolimus-treated patients. There were significantly more leukopenia and gastrointestinal adverse events in the MMF-treatment group. The incidence of posttransplant diabetes mellitus was 7.6% in the sirolimus group and 7.7% in the MMF group.. Tacrolimus is equally effective in renal transplantation when combined with sirolimus or MMF. The tacrolimus-MMF combination may be superior in terms of improved renal function and improved cardiovascular risk factors including hyperlipidemia and hypertension.

Black American heart transplant recipients receiving cyclosporine-based primary immunoprophylaxis suffer higher rates of allograft rejection with hemodynamic compromise, infections, and posttransplant coronary artery disease. We examined the hypothesis that a combination of tacrolimus and mycophenolate mofetil "resurrects" clinical outcome of black Americans to those seen in white heart transplant recipients.. Sixty-three adult primary heart transplant recipients were included in this study. Twenty black American and 21 white patients who received tacrolimus-based primary immunoprophylaxis were enrolled in this prospective, observational parallel cohort investigation. A separate group of 22 black American patients were randomly allocated to receive cyclosporine-microemulsion-based primary prophylaxis and served as the control population for assessing outcomes in the black American group. Adjunctive immunosuppression included mycophenolate mofetil and corticosteroids. The primary end-point was the freedom from allograft rejection requiring treatment at 1 year. Secondary end-points included rejection with hemodynamic compromise, and patient or graft survival. Adverse events evaluated included development of infections requiring hospitalization and nonimmunological outcomes including hyperlipidemia, hypertension, and diabetes mellitus (new onset or worsened).. Tacrolimus-treated black American patients had greater freedom from allograft rejection requiring treatment at 1 year than those treated with cyclosporine (64% vs. 37%, P=0.01). No differences were noted between tacrolimus-treated black Americans and whites in the primary end point (64% and 67% respectively, P=nonsignificant [NS]). Tacrolimus-based immunosuppression was associated with better 1-year survival in black Americans compared with cyclosporine (95% vs. 73%, P=0.04), and this end point was similar to that achieved in tacrolimus-treated white heart transplant recipients (95%). No differences in infection rates were noted among either group. Cyclosporine-treated black Americans suffered more hyperlipidemia and worse hypertension than tacrolimus-treated patients.. Compared with cyclosporine, an immunosuppressive strategy using tacrolimus in black Americans achieves superior efficacy with regard to allograft rejection, higher allograft survival, and similar safety. Furthermore, tacrolimus-based immunosuppression is similar in immunological efficacy and safety in black Americans and in white heart transplant recipients.

Hyperlipidemia is frequently developed following renal transplantation and results in worsening of the patient's prognosis. In study 1, the effects of immunosuppressants, cyclosporine (CsA) and tacrolimus on serum lipids were compared in-patients undergoing renal transplantation. The study included 32 cases of renal transplantation recipients who randomized to the CsA treatment group (15 patients) and the tacrolimus group (17 patients). Before and 1 month after the transplantation, we assessed the serum lipid levels, apolipoprotein levels, the concentrations of cholesterol in the respective lipoprotein fractions and the enzyme activities related to lipid-metabolism. The serum lipid levels in both groups were significantly increased at 1 month after renal transplantation. In the CsA group, there were significant increases in cholesterol contents in very-low-density lipoprotein (VLDL), LDL2 and HDL2 fractions, whereas, in the tacrolimus group, cholesterol content was increased in VLDL and HDL2 fractions. In study 2, 1 month after renal transplantation, 19 patients with hypercholesterolemia (total cholesterol (TC) >200 mg/dl) and hypertriglyceridemia (triglyceride (TG) >150 mg/dl) were treated with simvastatin 5-10 mg/day for 6 months. Simvastatin treatment significantly decreased serum TC (240+/-29-200+/-22 mg/dl, P<0.001), low-density lipoprotein cholesterol (LDL-C; 114+/-20-99+/-17 mg/dl, P<0.05) and TG levels (217+/-103-130+/-38 mg/dl, P<0.01). In addition, there were significant decreases in very-low-density lipoprotein cholesterol (VLDL-C; 53+/-20-34+/-15 mg/dl, P<0.001). The Cmax and AUC of simvastatin were increased about eight-fold, when simvastatin was given in combination with CsA. In contrast, no significant changes in simvastatin levels were observed when combination with tacrolimus. Although simvastatin levels were increased with CsA, there were no abnormal changes in renal and liver functions, creatinine phosphokinase (CPK) levels or in incidence of adverse effects.

As more than 90% of renal grafts retain their function 1 year after renal transplantation, side effects of immunosuppressive therapy gain more and more importance. In a randomised prospective study, we investigated the effects of conversion from cyclosporine A to tacrolimus due to hyperlipidemia in recipients of renal allografts. Fifty-seven patients with stable graft function treated with cyclosporine were randomly assigned to conversion to tacrolimus or continuation of their current therapy and followed for 1 year. Twenty-seven patients were switched and 30 patients remained on cyclosporine A. Cholesterol levels decreased significantly in the tacrolimus group as compared to controls in the intent to treat analysis. When only those patients were evaluated who received cyclosporine or tacrolimus during the whole study, statistical significance was even more pronounced. Triglyceride levels decreased in the tacrolimus group, whereas they increased in controls. Creatinine levels remained stable and no acute rejection was observed. A switch to tacrolimus is a safe alternative in cases of hyperlipidemia after renal transplantation.

Tacrolimus-based immunosuppression seems safe and effective in liver and kidney transplantation. To assess the safety and efficacy of tacrolimus (TAC)-based immunosuppression after cardiac transplantation as well as the relative impact of tacrolimus on immunosuppression-related side effects such as hypertension and hyperlipidemia, we conducted a prospective, randomized, open-label, multicenter study of otherwise identical tacrolimus- and cyclosporine-based immunosuppressive regimens in adult patients undergoing cardiac transplantation.. Eighty-five adult patients (pts) at six United States cardiac transplant centers, undergoing their first cardiac transplant procedure, were prospectively randomized to receive either TAC-based (n = 39) or cyclosporine (CYA)-based (n = 46) immunosuppression. All pts received a triple-drug protocol with 15 pts (18%) receiving peri-operative OKT3 to delay TAC/CYA due to pre-transplant renal dysfunction. Endomyocardial biopsies were performed at Weeks 1, 2, 3, 4, 6, 8, 10, 12, 24, and 52. The study duration was 12 months.. Patients were mostly male (87%) Caucasian (90%) with a mean age of 54 years and primary diagnoses of coronary artery disease (55%) and idiopathic dilated cardiomyopathy (41%). There were no significant demographic differences between groups. Patient and allograft survival were not different in the two groups. The probability and overall incidence of each grade of rejection, whether treated or not, and the types of treatment required did not differ between the groups. At baseline and through 12 months of follow-up, chemistry and hematology values were similar between the groups except serum cholesterol was higher in the CYA group at 3, 6, and 12 months (239 vs 205 mg/dL, 246 vs 191 mg/dL, 212 vs 186 mg/dL, respectively, p < 0.001). Likewise, LDL-cholesterol, HDL-cholesterol and triglycerides were significantly higher in the CYA group. More CYA patients received therapy for hypercholesterolemia (71% vs 41% at 12 months, p = 0.01). There were no significant differences in renal function, hyperglycemia, hypomagnesemia, or hyperkalemia during the first 12 months. More CYA patients developed new-onset hypertension requiring pharmacologic treatment (71% vs 48%, p = 0.05). The incidence of infection was the same for the two groups (2.6 episodes/pt/12 month follow-up).. Tacrolimus-based immunosuppression seems effective for rejection prophylaxis during the first year after cardiac transplantation and is associated with less hypertension and hyperlipidemia and no difference in renal function, hyperglycemia or infection incidence when compared to cyclosporine-based immunosuppression.

Tacrolimus has been shown to have a less adverse effect on the lipid profiles of transplant patients when the drug is started as induction therapy. In order to determine the effect tacrolimus has on lipid profiles in stable cyclosporine-treated renal transplant patients with established hyperlipidemia, a randomized prospective study was undertaken by the Southeastern Organ Procurement Foundation.. Patients of the 13 transplant centers, with cholesterol of 240 mg/dl or greater, who were at least 1 year posttransplant with stable renal function, were randomly assigned to remain on cyclosporine (control) or converted to tacrolimus. Patients converted to tacrolimus were maintained at a level of 5-15 ng/ml, and control patients remained at their previous levels of cyclosporine. Concurrent immunosuppressants were not changed. Levels of total cholesterol, triglycerides, total high-density lipoprotein, low-density lipoprotein (LDL), very-low-density lipoprotein, and apoproteins A and B were monitored before conversion and at months 1, 3, and 6. Renal function and glucose control were evaluated at the beginning and end of the study (month 6).. A total of 65 patients were enrolled; 12 patients failed to complete the study. None were removed as a result of acute rejection or graft failure. Fifty-three patients were available for analysis (27 in the tacrolimus group and 26 controls). Demographics were not different between groups. In patients converted to tacrolimus treatment, there was a -55 mg/dl (-16%) (P=0.0031) change in cholesterol, a -48 mg/dl (-25%) (P=0.0014) change in LDL cholesterol, and a -36 mg/dl (-23%) (P=0.034) change in apolipoprotein B. There was no change in renal function, glycemic control, or incidence of new onset diabetes mellitus in the tacrolimus group.. Conversion from cyclosporine to tacrolimus can be safely done after successful transplantation. Introduction of tacrolimus to a stable renal patient does not effect renal function or glycemic control. Tacrolimus can lower cholesterol, LDL, and apolipoprotein B. Conversion to tacrolimus from cyclosporine should be considered in the treatment of posttransplant hyperlipidemia.

Magnesium (Mg) is key in diabetes mellitus, hyperlipidemia, and cardiovascular disease.. This is a retrospective cross-sectional study including 103 kidney transplant recipients. Patients aged under 18 years, patients treated with Mg supplementation, antihyperlipidemic agents, or diuretics, and patients with active infection or malignancy were not enrolled. Patients were divided into 2 groups according to median serum Mg level. The atherogenic index of plasma was calculated by a logarithmic transformation of the number acquired by dividing the molar concentrations of serum triglyceride by high-density lipoprotein value.. The mean serum Mg level was 1.91 ± 0.28 mg/dL. Six patients (5.8%) had hypomagnesemia (Mg <1.5 mg/dL), and 2 (1.9%) had hypermagnesemia (Mg >2.6 mg/dL). Serum Mg level was negatively correlated with body mass index, estimated glomerular filtration rate (eGFR), and tacrolimus trough level and positively correlated with levels of phosphorus, total cholesterol, and low-density lipoprotein (LDL-C). There was no correlation between serum Mg and triglyceride, high-density lipoprotein, atherogenic index of plasma, and cyclosporin A trough level. Patients with Mg >1.87 mg/dL had lower eGFR, tacrolimus, and cyclosporin A trough level and higher total cholesterol and LDL-C compared to those with Mg ≤1.87 mg/dL. In adjusted ordinal analysis, eGFR (hazard ratio (HR): 0.981, 95% CI 0.964-0.999, P = .036) and total cholesterol (HR: 1.015, 95% CI 1.004-1.027, P = .008) were independently associated with serum Mg. In multivariate linear regression analysis, serum Mg level was independently associated with LDL-C (β = .296, t = 3.079, P = .003) and total cholesterol (β = .295, t = 3.075, P = .003).. Serum Mg level may have an important impact on dyslipidemia in kidney transplant recipients.

Hyperlipidemia is not unusual in liver transplant recipients, but refractory severe hyperlipidemia is unusual. We treated a 39-year-old man who had severe dyslipidemia after liver transplant. The levels of blood lipids, liver enzymes, and essential indicators of liver pathology were monitored. The first serum sample was collected from the liver recipient 56 days after transplant surgery because samples could not be obtained sooner after the transplant. The levels of liver enzymes and blood lipids were improved with symptomatic treatment but had recurrent fluctuations. Tacrolimus and cyclosporine, even at low doses, may have been the dominant factor affecting the blood lipid levels in the recipient.

The arrival of tacrolimus has drastically improved AALDLT recipients' survival. However, little data of tacrolimus have been reported concerning its effects on lipid metabolism for AALDLT recipients.. Out aim was to investigate the relationship between tacrolimus blood concentration and lipid metabolism in AALDLT recipients.. The pre and postoperative data of 77 adult patients receiving AALDLT between 2002 and December 2007 were retrospectively reviewed. The postoperative immune suppressive regimen was prednisone with tacrolimus ± mycophenolate mofetil. Prednisone was withdrawn within the first postoperative month. Blood lipids and tacrolimus concentration were detected at the first, third, and sixth month during follow-up. Episodes of acute rejection were diagnosed based on biopsy.. Overall prevalence of post-transplantation hyperlipidemia was 29.9% (23/77) at the sixth postoperative month. The patients were divided into two groups, the hyperlipidemia group and the ortholipidemia group. In the 23 patients with hyperlipidemia, 15 (65%) were hypercholesterolemia, five (22%) were hypertriglyceridemia, and three (13%) patients had both hypercholesterolemia and hypertriglyceridemia. In univariate analysis, only tacrolimus blood concentration at the third and sixth post-transplantation months showed significant difference (8.7 ± 2.1 vs. 6.9 ± 3.2, p = 0.013; 9.2 ± 2.7 vs. 7.3 ± 3.8, p = 0.038, respectively). In multivariate logistic analysis, only two factors appear to be risk factors, namely, tacrolimus blood concentration at the third and sixth post-transplantation months (8.7 ± 2.1 vs. 6.9 ± 3.2, p = 0.043; 9.2 ± 2.7 vs. 7.3 ± 3.8 p = 0.035, respectively).. Higher tacrolimus blood concentration was related to hyperlipidemia at an early postoperative period. This indicates that tacrolimus blood concentration should be controlled as low as possible in the premise that there is no risk of rejection to minimize post-transplant hyperlipidemia after AALDLT.

The purpose of this study was to characterize the effects of clinical and genetic variables on the pharmacokinetics and complications of tacrolimus during the first year after kidney transplantation.. One hundred and thirty-two Korean kidney recipients who received tacrolimus were genotyped for ABCB1 (exons 12, 21, and 26) and CYP3A5 (intron 3). Tacrolimus trough levels, dose, or dose-adjusted trough levels and complications were compared among patients during the early stage (3, 7, 14, 30, and 90 days) and up to 1 year according to the genotypes.. A donor source-adjusted linear mixed model with multilevel analysis adjusting for age, body weight, hematocrit, and serum creatinine showed that CYP3A5 genotype is associated with dose-adjusted level of tacrolimus (p < 0.001). The influence of ABCB1 polymorphisms on the pharmacokinetics or complications of tacrolimus was less certain in our study. The incidence of acute rejections was significantly higher in recipients of cadaveric donor kidney (p < 0.05).. A generalized estimating equation model analysis showed that alopecia and hyperlipidemia were associated with dose-adjusted level of tacrolimus (p < 0.001). Genotype of CYP3A5 variants along with significant clinical covariates may be useful in individualizing tacrolimus therapy in kidney transplantation patients.

To evaluate the efficacy and safety of conversion from calcineurin inhibitors to sirolimus among liver transplant recipients with calcineurin inhibitor-induced complications.. After receiving liver transplants, 25 patients with calcineurin inhibitor-induced complications (22 renal dysfunction and 3 new-onset diabetes mellitus) were converted from sirolimus to tacrolimus. The serum creatinine, sirolimus trough level, liver function, acute rejection episodes, and drug-related adverse effects were monitored.. The patients were followed for 12 to 50 months (median, 25 months). The renal function of the 22 patients with renal dysfunction improved after sirolimus conversion. The serum creatinine levels were significantly lower at 3 months after conversion versus before conversion (113.2 ± 21.8 μmol/L vs 163.2 ± 45.3 μmol/L; P < .05). At the end of the follow-up, the average serum creatinine level was 101.9 ± 23.4 μmol/L among the 20 living recipients. Diabetes also was under control in 3 diabetic recipients after the conversion. Four patients experienced episodes of acute rejection, and intravenous steroid bolus therapy was administered in 2 of them. No graft was lost because of acute rejection. The adverse effects of sirolimus included hyperlipidemia (7/25), anemia (8/25), and mouth ulcers (9/25). All these adverse effects were relieved after a short-term symptomatic therapy, and no patient was withdrawn from the conversion trial.. Sirolimus monotherapy is effective and safe in liver transplant recipients. Conversion to sirolimus was associated with a sustained improvement in renal function and diabetes mellitus without an increased incidence of acute rejection episodes.

Tacrolimus (Tac) in combination with mycophenolate mofetil is widely used after heart transplantation (HT). Everolimus (EVR), a new potent proliferation signal inhibitor can be used with a carcineurin inhibitor to reduce the occurrence of rejection. The purpose of this study was to evaluate the efficacy and safety of Tac combined with EVR in de novo HT.. From January 2009 to April 2011, 33/62 patients who underwent HT were prescribed Tac and EVR as de novo immunosuppression. The main exclusion criteria were poor kidney function (serum creatinine > 2.8 mg/dL), panel-reactive antibodies > 25%, donors > 60 years old, or cold ischemia time > 6 hours. All patients received Tac (C0 blood level 5-10 ng/mL during the first 6 months, then 3-5 ng/mL), EVR (C0 target 3-8 ng/mL), and corticosteroids. After transplantation, routine examinations included echocardiogram and protocol endomyocardial biopsy.. There was no operative mortality. The 1- and 3-year actuarial survivals were 95.74% ± 3.49%. One patient who had undergone coronary artery bypass grafting previously and received intra-aortic balloon pumping and extracorporeal membrane oxygenator-assisted cardiopulmonary resuscitation before HT died of Aspergillus septicemia 58 days after HT. No biopsy-proven acute rejection > grade 2R or acute rejection associated with hemodynamic compromise was observed. Hyperlipemia was noted in 16 cases (48.5%), hypertension in 11 (33.3% 5%), and diabetes mellitus in 12 (36.4%). No other severe adverse events were noted.. Concentration-controlled EVR (C0 target 3-8 ng/mL) in combination with Tac achieved good efficacy and safety. The 1- and 3-year actuarial survivals were 95.74% ± 3.49%.

To observe the influence of ciclosporin A (CsA) or/and FK506 on vascular endothelium of hyperlipidemic rats.. Hyperlipidemic rat model was established as previously described. The injury of vascular endothelium of these rats was observed after stimulation with FK506 or/and CsA. The mRNA transcription and protein expression of the vascular endothelium growth factor (VEGF), decay-accelerating factor (DAF) and C reactive protein (CRP) in vascular endothelium of rats were measured. The serum reactive oxygen species (ROS) was detected.. Compared with FK506, CsA was more likely to cause injury of vascular endothelium, damaging the integrity of endothelium of hyperlipidemic rats. CsA inhibited the expression of VEGF and the complement inhibitor DAF and increased the expression of CRP of vascular endothelial cells. CsA also up-regulated the serum level of ROS. FK506 showed no such impacts.. CsA can damage vascular endothelium of hyperlipidemic rats by activating the complement system induced by VEGF/DAF and ROS/CRP pathway. FK506 has no influence on the VEGF/DAF pathway and the expression of ROS/CRP.

Maintenance therapy with calcineurin inhibitors (CNIs) increases cardiovascular risk. Use of the m-TOR inhibitors everolimus or sirolimus to minimize CNI exposure is usually undertaken to preserve renal function following kidney transplantation, but may also improve cardiovascular risk status. Recent studies of early conversion from CNI to m-TOR inhibitors have shown a numerical improvement in the incidence of hypertension, but results are not clear-cut. Dyslipidaemia, in contrast, is more frequent under m-TORs than with CNI-based immunosuppression. New-onset diabetes is rare (≤ 5%) using modern m-TOR regimens, for example, everolimus and reduced-exposure CNI. Renal function improvement with m-TOR inhibitor regimens versus CNIs would also be expected to improve cardiovascular risk. Moreover, m-TOR-based CNI-minimization regimens are not associated with proteinuria, a known cardiovascular risk factor, with the possible exception of late conversion in patients with poor renal function. Interestingly, m-TOR inhibitors may also exert cardioprotective effects. Animal data suggest that m-TORs may restrict the pathogenesis of atherosclerosis, consistent with preliminary clinical data that conversion from CNIs to everolimus can stabilize markers for arterial stiffness. In conclusion, use of m-TORs has the potential to lessen the toll of cardiovascular disease following kidney transplantation - an opportunity that merits further exploration.

The main objectives of this study were to estimate the prevalence of and the risk factors for the adverse effects of tacrolimus-based immunosuppression in patients who obtained renal transplant from living donors.. A multicenter cross-sectional observational study in 154 kidney transplant patients who received grafts from living donors.. Large proportion of patients had hypertension (83%) and hyperlipidemia (53%); 27% had posttransplant diabetes mellitus. Patients had on average two chronic diseases. Tremor was present in 40%, neurologic toxicity in 45%, and anemia in 51.5% of patients. The average number of adverse effects was 3.52 ± 1.57. In multivariate analysis some adverse effects were related to tacrolimus concentration, duration of treatment, number of medications or medical problems. In linear regression analysis correlation was found, among the others, between diastolic blood pressure and tacrolimus concentration, and inverse correlation between erythrocyte count and duration of treatment.. There is a significant prevalence of tacrolimus adverse effects and supratherapeutic TAC blood concentrations in Jordanian renal transplant patients in spite of using low TAC doses and overall adequate renal function.

The present study was designed to investigate the effect of low-dose calcineurin inhibitor (CNI) tacrolimus combined with a mammalian target of rapamycin (mTOR) inhibitor on renal function in transplant recipients without allograft nephropathy.. Twelve patients including seven men (58.3%) of overall mean age of 34.8 ± 14.1 years underwent renal transplantation and were switched to a new second-line treatment of low-dose CNI combined with an mTOR inhibitor, either sirolimus or everolimus.. The underlying cause of renal failure was not clear in half of the cases; for the others it was chronic glomerulonephritis, diabetic nephropathy, polycystic kidney disease, or hypovolemia. After 6 months of the new therapy, there was a significant increase in calculated creatinine clearance levels compared to baseline (75.5 ± 21.9 vs 89.6 ± 19.1 mL/min; P < .001), but no significant change in serum creatinine (1.3 ± 0.4 vs 1.2 ± 0.3 mg/dL) or urinary protein excretion (187.5 ± 142.0 vs 394.0 ± 326.4 mg/g). For almost all patients, proteinuria remained stable, but in two patients, it developed but responded to enalapril treatment. Dose decrement was required for four patients with hyperlipidemia (50%); one patient experienced new-onset hyperlipidemia that responded to treatment. One patient developed a urinary tract infection that responded to antibiotic treatment. None of the patients developed an acute rejection episode.. Low-dose CNI combined with an mTOR inhibitor, as a replacement for mycophenolate mofetil or enteric-coated mycophenolate sodium, seemed to prevent renal dysfunction for at least 6 months among renal transplant patients without allograft nephropathy.

Tacrolimus and Cyclosporine A (CyA) are cornerstones in immunosuppressive therapy. Cyclosporine side eff ects include hypertension and hypercholesterolemia both of which may increase the risk of cardiovascular mortality, gingival hyperplasia and hirsutism are known to reduce quality of life. The aim of this prospective study was to evaluate changes in cardiovascular risk profile and cosmetic side eff ects after conversion from CyA to tacrolimus.. 25 stable kidney transplant recipients (9 male, 16 female) were converted from a CyA to a tacrolimus--based regimen. Mean age was 45.7 +/- 13.5 years. Time to switch following transplantation was 4.7+/-1.7 years. Reasons for conversion were multiple: arterial hypertension (9), hypertrichosis (3), gingival hyperplasia (3), hyperlipidemia (14).. 19/25 patients completed the one year study period. One patient died, two returned to hemodialysis, two were switched back to CyA and one patient was lost to follow-up. There were statistically significant changes (p = < 0.05) in systolic and diastolic pressure and antihypertensive medication could be reduced in 13 patients. The dose of lipid-lowering agents could be reduced in the majority of the recipients and a complete withdrawal was achieved in 7 patients. Hypertrichosis and gingival hyperplasia resolved in all patients. Further, there was a significant improvement (p = <0.05) in urea and serum creatinine levels. Adverse events were consistent with the established safety profile for tacrolimus.. Conversion to a tacrolimus-based regimen led to an improvement in the cardiovascular risk profile. Further, cosmetic side eff ects which may lead to non-compliance, resolved after the switch.

Cardiovascular disease (CVD) accounts for 35% to 50% of deaths among renal transplant recipients. Beside the atherogenic risk factors related to hemodialysis, renal function, and use of immunosuppressive agents, other relevant risk factors for CVD include acute rejection episodes, microalbuminuria (muAlb), diabetes, arterial hypertension, lipid disorders, inflammatory triggers, hyperhomocysteinemia, anemia, erythrocytosis, obesity, and hyperuricemia. We studied the prevalence of risk factors and the impact of various drugs on CVD among 103 renal transplant recipients with measured glomerular filtration rates showing values >45 mL/min. We measured uric acid, triglycerides (TG), low-density lipoprotein (LDL)/high-density lipoprotein (HDL) LDL/HDL ratio, homocysteine (HOMO), insulin resistance, muAlb, C-reactive protein (CRP), and fibrinogen. Subsequently, patients were divided into 8 groups based on the immunosuppressive protocol to evaluate its impact on CVD risk factors. Insulin resistance and hyperhomocysteinemia were present in >2/3 of patients. Considering the impact of protocols, the combination of cyclosporine (CsA) + everolimus (EVL) resulted in the most favorable profile in terms of reduction of hyperuricemia, hyperlipidemia, and hyperhomocysteinemia. Insulin resistance tended to be more frequent among patients treated with protocols including calcineurin inhibitors (CNI) and steroids. The prevalence of hyperhomocyteinemia was similar among patients on CsA and on tacrolimus (Tac). Sirolimus (SRL) was associated with higher levels of HOMO. The combination of CNI and proliferative signal inhibitors (PSI) seemed to be the most promising one to reduce the impact of CVD risk factors. The reduction in CVD morbidity can improve expectancy and quality of life, as well as graft function and survival among renal transplant patients.

BACKGROUND.: Sirolimus (SRL) is an important component of clinical immunosuppression in renal transplantation, but few international studies have examined how this agent is used in routine practice. METHODS.: Within a large prospective pharmacoepidemiological study, 718 de novo renal graft recipients treated with SRL in 65 centers in 10 countries were monitored for up to 5 years posttransplant to compare the principal outcomes and adverse effects by treatment regimen. RESULTS.: Principal treatment regimens were SRL without a calcineurin inhibitor (33%), SRL+cyclosporine A (CsA) (33%), and SRL+tacrolimus (TAC) (34%); 18% of subjects discontinued SRL, 124/718 (17%) developed biopsy-confirmed acute rejection (BCAR), 64/718 (9%) lost their graft, and 50/718 (7%) died during follow-up. Calculated creatinine clearance was 66+/-26 mL/min at 2 years. The most common adverse events were hypertension, hyperlipidemia, anemia, urinary tract infections, and diabetes. BCAR was significantly lower in subjects receiving SRL+TAC (hazard ratio [HR] 0.46, P=0.009) but not significantly lower in those receiving SRL+CsA (HR 0.62, P=0.102) compared with SRL without a calcineurin inhibitor. Graft loss or death did not significantly differ between treatment groups but were associated, respectively, with deceased donor grafts (HR 3.33, P<0.001) and increased age (HR 1.04, P<0.001). No improvement was observed in patients receiving mycophenolate mofetil in any treatment combination (HR 0.80, P=0.438 for BCAR; HR 0.93, P=0.849 for graft loss; and HR 0.75, P=0.531 for death). CONCLUSIONS.: SRL is most commonly used in combination with mycophenolate mofetil, CsA, or TAC. BCAR was least common in subjects receiving SRL+TAC, but other outcomes seemed comparable between the treatment regimens in routine practice.

In renal transplant recipients, cyclosporine treatment appears to cause more frequent hyperlipidemia than tacrolimus usage. In this study, hyperlipidemic renal transplant recipients who use cyclosporine were investigated for changes in high-density lipoprotein (HDL)-2/3, apolipoprotein (Apo) A1/B, other lipid and biochemical parameters, and body mass index after prospective cyclosporine to tacrolimus switching.. Fifteen patients, including 9 females of overall mean age of 33.2 +/- 10.7 years and posttransplantation time of 78.06 +/- 42.93 months with a mean body mass index of 23.77 +/- 3.34 kg/m(2), were included if they were nondiabetic, hyperlipidemic, and had undergone renal transplantation between 1992 and 2000, using cyclosporine and candidates for a switch to tacrolimus due to hyperlipidemia. Before switching to tacrolimus and at 12 months of tacrolimus use we studied fasting blood samples for creatinine, uric acid, glucose, triglyceride, Apo A1, Apo B, low-density lipoprotein (LDL), HDL2, HDL3, and total cholesterol.. There were no significant differences in creatinine, uric acid, glucose levels, or body mass index before tacrolimus versus 12 months thereafter. It was observed that tacrolimus significantly decreased triglyceride, Apo A1, Apo B, LDL, HDL, and total cholesterol levels (P < .001; P = .006; P = .01; P < .001; P = .03; P .05).. Switching from cyclosporine to tacrolimus was associated with a more favorable cardiovascular risk profile by improving hyperlipidemia.

This retrospective study was conducted to assess the efficacy and safety of immunosuppression conversion on progression of chronic allograft nephropathy (CAN).. One hundred-seventy four cyclosporin (CsA)-treated renal transplant recipients were studied. Patients were included if they had a biopsy-proven CAN (mild to moderate) with serum creatinine < or =3.5 mg/dL. Patients were treated with either: (A) MMF/reduced dose CsA [MMF for azathioprine (Aza)] (n=132); (B) Aza/Tac for CsA (n=42). Patient records were checked for graft function and survival, co-morbidities after conversion.. Mean follow-up before conversion was 52.2+/-31.1 and 47.9+/-27.4 month in-group A and B, respectively. There was a significant deterioration of graft function in-group B after 5-years (P<0.5). Ten-year actuarial graft survival was 38% in-group A and 19% in-group B (P=0.04). Nine patients started dialysis within 12 months. Tacrolimus-treated patients had a lower insignificant incidence of hyperlipidemia (P=0.05), but a significantly higher incidence of diabetes mellitus (P=0.04).There was no significant change or difference in blood pressure between groups.. Our results suggest that in patients with CAN and deteriorating allograft function, CsA minimization and addition of MMF achieved favorable efficacies in retarding the decline of graft function. Further prospective studies with larger cohorts are needed for validation.

Hyperlipidemia following successful renal transplantation is a frequent and persistent complication. Several immunosuppressive agents including cyclosporine A (CyA), corticosteroids, and tacrolimus appear to have a significant pathogenetic role. The aim of this study is to investigate the differential effects of different immunosuppressive agents on lipids in renal transplant patients.. Two groups of renal transplant recipients, each treated with a different combination of immunosuppressive agents, were studied: Group A (n = 13), cyclosporine A, mycophenolate mofetil (MMF), steroids, and basiliximab; Group B (n = 13), tacrolimus, MMF, steroids, and daclizumab). Plasma lipids [cholesterol (CHOL), low-density lipoprotein (LDL)-CHOL, high-density lipoprotein (HDL)-CHOL, and triglycerides (TG)] were examined before transplantation and 1 and 6 months posttransplantation.. The patients treated with cyclosporine A-MMF showed a significant increase in mean cholesterol and mean LDL-cholesterol values at the 1-month posttransplantation follow-up compared with pretransplant levels (CHOL: 208.9 +/- 47.4 vs. 268.7 +/- 42.2 mg/dl, P = 0.004; LDL: 118.4 +/- 49.9 vs. 198.7 +/- 40.7 mg/dl, P = 0.002; pretransplant vs. 1 month, respectively). At 6 months, LDL-cholesterol levels were significantly elevated compared with pretransplant levels (LDL: 118.4 +/- 49.9 vs. 148.3 +/- 48.5 mg/dl, P = 0.034), whereas there was no significant change in the cholesterol level during the same period. In cyclosporine A-MMF-treated patients, plasma triglyceride levels were reduced at the 1- and 6-month follow-up (TG: 293.9 +/- 59.2 vs. 182.9 +/- 48.7 mg/dl, P = 0.03; 293.9 +/- 59.2 vs. 178.6 +/- 74.2 mg/dl, +/- = 0.023; pretransplant vs. 1 and 6 months, respectively). Patients receiving combined therapy with tacrolimus-MMF showed no significant changes in LDL-CHOL levels during the trial. Cholesterol levels at 6 months posttransplantation were significantly lower than the pretransplant measurements (CHOL: 182.9 +/- 44.4 vs. 162.3 +/- 37.2 mg/dl, P = 0.024; pretransplant vs. 6 months). A significant reduction in triglyceride level was documented at the 1-month follow-up followed by a subsequent decrease within 6 months (TG: 228.5 +/- 61.6 vs. 147.6 +/- 51.5 mg/dl, P = 0.005; TG: 228.5 +/- 61.6 vs. 130.4 +/- 54.7 mg/dl, P = 0.011; pretransplant vs. 1 and 6 months, respectively).. In posttransplant patients with stable renal function cyclosporine therapy is associated with increased cholesterol and LDL-cholesterol levels. Hyperlipidemia is less pronounced in patients given tacrolimus. Tacrolimus appears to an immunosuppressant agent with fewer and less severe adverse effects on lipid metabolism.

Controversy exists over the pattern of lipidemic effects from calcineurin inhibitors and prednisone. We report an extensive longitudinal study of lipid profiles in pediatric thoracic transplant recipients.. Serial fasting lipids of subjects from a single pediatric center, along with their immunosuppressive regimens, were examined. Groups were analyzed according to cyclosporine- or tacrolimus-based immunosuppression in addition to whether prednisone was used as adjunctive therapy.. Of a total of 119 subjects, 85 were and remained on tacrolimus (TAC), 13 remained on cyclosporine (CSA), 4 switched from TAC to CSA, and 17 switched from CSA to TAC. The median age at transplant was 100 months, and the latest follow-up was 48 months. The CSA Group had higher lipid levels than the TAC Group, and levels changed minimally over time. At 1 year, TAC vs CSA total cholesterol was 153 vs 186 mg/dl (p = 0.002), low-density lipoprotein (LDL) cholesterol was 92 vs 117 (p = 0.09), and high-density lipoprotein (HDL) cholesterol was 42 vs 48 (p = NS), respectively. At the latest follow-up, the TAC vs CSA cholesterol was 143 vs 180 mg/dl (p = 0.001), LDL was 84 vs 115 (p = 0.001), and HDL was 42 vs 41 (p = NS). Profiles of subjects that switched agents reflected the agent used (e.g., higher total cholesterol, LDL, and HDL while on cyclosporine). Sub-group analysis showed prednisone augmented the hyperlipidemic effects.. Hyperlipidemia is common in pediatric thoracic transplant patients and persists over time. It is more pronounced in cyclosporine subjects and is further elevated with prednisone. These findings indicate the need for close monitoring, and consideration for intervention, especially in high-risk sub-groups.

To measure the effect on serum lipids and other risk factors for cardiovascular disease, we converted the primary immunosuppression of dyslipidemic stable liver transplant recipients from cyclosporine A to tacrolimus.. Patients underwent a four-month dietary stabilization period (American Heart Association Step II diet) and serum lipid samples were collected for analysis at a central laboratory. After conversion, dietary counseling and lipid analyses were performed over a six-month postconversion observation period.. Enrollment was terminated prematurely due to low patient recruitment rates. Thirteen patients were enrolled and provided postconversion data showing surprisingly strong results. At six months postconversion, total cholesterol (C) was reduced by a mean of 0.61 mmol/L (P=0.017), high density lipoprotein cholesterol (HDL-C) remained unchanged; the mean total C:HDL-C ratio was reduced by 0.87 (P=0.001). Low density lipoprotein cholesterol (LDL-C) reductions were not statistically significant, but we observed a significant and persistent decrease in apolipoprotein B (-0.15 g/L six months postconversion, P=0.031). No changes in homocysteine or in vitamins B6 and B12 were discerned, but although red cell folate remained stable, serum folate increased after conversion. We observed no rejection episodes or any other clinically notable events following conversion.. In this study, conversion from cyclosporine to tacrolimus provided a safe and well-tolerated alternative that reduced hyperlipidemia and other recognized cardiovascular risk factors.

Corticosteroids have been a component of maintenance immunosuppression for renal transplant since the 1960s and have helped to reduce the rate of acute rejection. Corticosteroids, however, have many adverse effects, and with the development of new immunosuppressive medications, many transplant centers have adopted protocols that eliminate or completely avoid the use of corticosteroids. Despite promising short-term results, the impact of corticosteroid elimination on long-term kidney function still is unclear. This single-center, retrospective, sequential study analyzed 212 renal transplant patients with a median follow-up of 5 yr. All patients received induction with IL-2 receptor antagonist and maintenance immunosuppression with mycophenolate mofetil and tacrolimus. Ninety-six patients were maintained on chronic prednisone, and 116 were maintained without chronic prednisone (rapid steroid elimination). Kaplan-Meier patient and graft survival at 7 yr after transplantation were not statistically different between the two groups. Rate and severity of acute cellular rejection were similar. Furthermore, the slope of GFR decline per month at 5 yr after transplantation was not statistically different between the two groups. Prednisone-treated patients had a significantly higher incidence of hyperlipidemia and posttransplantation diabetes when compared with patients with rapid steroid elimination. It was concluded that with the current immunosuppressive medications, the use of chronic prednisone to maintain long-term kidney function and prevent acute cellular rejection is not justified.

The primary aim of this study was to assess the safety and efficacy in lung transplantation of an immunosuppressive regimen aimed at achieving sirolimus and tacrolimus concentrations of 6 to 10 microg/ml and 5 to 7 ng/ml, respectively.. We retrospectively identified 49 lung transplant recipients who were converted to an immunosuppressive regimen consisting of tacrolimus, sirolimus, and prednisone. Data collected included demographic information, laboratory work, episodes of rejection, bronchiolitis obliterans syndrome (BOS) grade, and adverse effects.. The most common reason for conversion to a sirolimus and tacrolimus regimen was BOS. The most common adverse effects were increased triglycerides (10%), leukopenia (8%), and skin rash (6%). Four patients (8%) experienced acute allograft rejection during the study period. We followed BOS grade for 1 year in 23 patients. Of these, BOS grade improved in 8, 13 patients remained unchanged, and 2 worsened. Eleven patients (22%) discontinued sirolimus because of adverse events.. An immunosuppressive regimen consisting of sirolimus and tacrolimus that aims to keep the trough drug concentrations at 6 to 10 microg/ml and 5 to 7 ng/ml, respectively, provides effective lung allograft protection while maintaining an acceptable side-effect profile. The use of this immunosuppressive combination may have a benefit with regard to BOS.

The main rheological properties of red blood cells (RBC) are deformability and aggregability. Deformability is one of the most important factors of RBC flow in high-shear rate areas, especially in the microcirculation. Aggregability of erythrocytes can impair circulation in low-shear rate areas. Both deformability and aggregability of RBC are abnormal in patients with renal insufficiency and after kidney transplantation. Cyclosporine (CsA) and less frequently tacrolimus (Tc) may cause hyperlipidemia and hypertension. Dobiasova et al proposed the term Atherogenic Index of Plasma (AIP), defined as a log (TG/HDL-C). Subjects with high AIP have and higher risk of cardiovascular complications due to atherosclerosis. Hence the aim of this study was to compare aggregability and deformability of RBC from kidney transplant recipients on CsA or Tc-based immunosuppression with healthy volunteers and subjects with dyslipidemia (control groups). Both control and transplant recipient groups were arbitrarily divided by value of AIP as < or = 0 (AIP-) or >0 (AIP+). Deformability and aggregability of erythrocytes were measured using Rheodyn SSD and Myrenne Aggregometer, respectively.. We observed a significant increase in aggregation index at stasis in CsA-treated patients and an increased deformability in Tc-treated patients with negative AIP. Deterioration of hemorheological properties of RBC in kidney transplant recipients was confined to an increased aggregability in CsA-treated patients regardless of AIP value. An increased deformability of RBC in Tc-treated patients with normal lipid profiles may suggest a positive effect of Tc on mechanical properties of RBC.

The efficacy and safety of tacrolimus (FK506; Prograf) were determined in 28 adult kidney transplant patients (20 males and 8 females), aged 18-68 years (mean+/-S.D.: 46.9+/-4.03 years). Induction therapy was ATG-F (n=23), daclizumab (n=3), or none (n=2), and maintenance immunosuppression consisted of tacrolimus, combined with mycophenolate mofetil (MMF; n=26) or azathioprine (AZA; n=2) and prednisone (Pred). In seven patients, cyclosporine A microemulsion (Neoral) was replaced by tacrolimus for acute rejection (AR; three patients), slow graft function (SGF, two patients) and Neoral side effects (two patients). Acute rejection occurred in five patients (17.8%), three of whom were steroid-resistant treated with a second course of ATG-F. Infection occurred in 10 patients (35.7%) with a total of 15 infectious episodes, comprising bacterial (73%) and viral (27%) infections related to CMV. Other side effects related to tacrolimus were hypertension in four patients (14%) and post-transplantation hyperglycemia in nine patients (32%), three of whom required insulin therapy. In addition, hypercholesterolemia and hypertriglyceridemia occurred in six (21%) and eight patients (28.5%), respectively. The patient's hospital stay was 12.7+/-1.3 days (range: 8-24 days), and mean serum creatinine upon discharge, and at 1, 3 and 6 months following transplantation were: 2.1+/-0.5, 1.47+/-0.21, 1.41+/-0.53 and 1.23+/-0.11 mg/dl, respectively. The 6-month actuarial patient and graft survival rates were 100%. While tacrolimus is an effective calcineurin inhibitor for kidney transplantation (KT), severe acute rejection seen is related to highly sensitized patients, and the CMV infections noted were related to the presence of more CMV-negative recipients receiving kidneys from CMV-positive donors. Longer follow-up with a larger patient sample is needed to fully assess both the efficacy and safety of tacrolimus, including its metabolic effects.

Calcineurin inhibitors (CIs) contribute to cardiovascular risk (CR) in renal transplant (RT) patients. However, the CR profile in RT patients without preexistent diabetes is not well known. We compared CR factors in 191 nondiabetic RT recipients with functioning grafts beyond 1 year, receivingly either CsA (Neoral; n=100) or tacrolimus (Tac; n= 91). Clinical data and pretransplant CR profiles were similar in both groups. There were no differences in acute rejection episodes and graft survival rates during follow-up. The overall proportions of posttransplant diabetes (9% versus 6%), and of hypertension (73% vs 63%) were similar in both groups. Hyperlipidemia was more frequent in the CsA group (58% vs 31%; P=.0001). The cholesterol levels in the CsA group showed at 3 months (232+/-47 vs 202+/-42 m/dL; P=.0001), 6 months (232+/-49 vs 205+/-41 mg/dL; P=.0001), and 12 months (217+/-50 vs 202+/-40 mg/dL; P=.028), despite receiving a greater proportion of lipid-lowering drugs (49% vs 15%; P=.0001). Logistic regression analysis showed that CsA was an independent predictor of posttransplant hyperlipidemia (OR: 5.8, CI 95%; 3.3-10.7; P=.0001) as were age, female gender, pretransplant dyslipidemia, and body mass index (BMI). Interestingly, an interaction was observed between pretransplant BMI and CIs: Among pretransplant normal weight patients (BMI <25 kg/m2), CsA produced a greater incidence of hyperlipidemia than tacrolimus (58% vs 23%; P=.0001) while not among patients who were overweight (BMI >25 kg/m2: pretransplant 58% vs 42%; P=.341). In conclusion, CsA confers a higher risk of hyperlipidemia after RT in nondiabetic patients, particularly those with normal pretransplant weight.

This multicenter study was retrospectively evaluated for the predictive factors affecting the long-term graft survival of a kidney transplant from a non-heart-beating donor (NHBD).. A total of 706 patients received transplants from NHBD in 11 centers between 1986 and 2000 and the results were entered into the analysis. The patients were treated with cyclosporine- or tacrolimus-based immunosuppressive therapy. Graft survival was calculated by the Kaplan-Meier method. Factors selected for univariate analysis were donor age, and acute early and acute late rejection. Hypertension (HT), hyperlipidemia (HL), and diabetes mellitus were also analyzed in 638 recipients whose graft survived for more than 1 yr.. In the cases using NHBD, graft survival for 1, 5, and 10 yr was 87, 69, and 53%, respectively. Donor age of over 55 yr, acute early and late rejection, post-transplant HT and diabetes at the first post-operative year were shown to be significantly harmful on long-term graft survival. For longer graft survival in NHBD kidney transplantations, reducing acute rejection, and controlling blood pressure and sugar are crucial.

Cyclosporin A is a lipogenic immunosuppressor that can induce posttransplant hyperlipidaemia. Oxidation of low-density lipoprotein (LDL) has been recognized as a major atherogenic factor. Tacrolimus seems to be less lipogenic with an apparently better cardiovascular profile than CsA.. We have studied the lipidic profile and the oxidation of HDL and LDL in 20 renal transplant patients, 12 male and 8 female, mean age 45 +/- 10 year, who where switched from CsA to tacrolimus due to CsA adverse effects. LDL were determined by ultracentrifugation. Oxidation study before and 6 months after conversion to tacrolimus was performed by adding CuSO4.. After conversion, systolic blood pressure (BP) decreased from 154 +/- 21 to 133 +/- 21 mm Hg (p = 0.008), diastolic BP from 97 +/- 13 to 77 +/- 15 mm Hg (p = 0.016), total cholesterol from 6.08 +/- 0.9 to 5.68 +/- 1.1 mmol/l (p = 0.02), LDL-chol from 3.29 +/- 1.01 to 2.96 +/- 0.3 mmol/l (p = 0.04) and apo-B lipoprotein from 1.42 +/- 0.28 to 1.15 +/- 0.34 mg/dl (p = 0.003). The oxidation of LDL improved after conversion: the initial dienic compounds decreased from 95 +/- 20 to 63 +/- 12 umol/g and the final DC from 207 +/- 56 to 107 +/- 35 umol/g. Lag-phase increased from 33 +/- 21 to 45 +/- 17 min (p < 0.05).. Tacrolimus has improved hyperlipidaemia in our cyclosporin previously treated patients and increased the resistance to oxidation of high and low-density lipoproteins.

Recent reports have demonstrated the efficacy of interleukin-2-receptor blockers in lowering the incidence of early acute rejection in cyclosporine-treated kidney recipients when compared to patients not induced with an antibody product. The addition of daclizumab to a tacrolimus-mycophenolate mofetil-based immunosuppressive protocol was tested to evaluate whether there might be an additional reduction of the risk of rejection after renal transplantation.. Since March 1998, we studied the effect of daclizumab in a nonrandomized, prospective study of 233 sequential recipients of first renal transplant. They were retrospective compared with a control group of 225 renal transplant recipients receiving a 10-day course of OKT3 induction, and tacrolimus, mycophenolate mofetil, and methylprednisolone maintenance. The study group received the same immunosuppressive regimen with the addition of daclizumab at 1 mg/kg for five doses over 10 weeks in the place of OKT3 therapy. There was at least 1HLA DR antigen compatibility match present between all donors and recipients. Patients were followed for 1 year after renal transplantation for the incidence of biopsy-proven acute rejection, patient and graft survival, and adverse events.. At 12 months, patient and graft survival for the daclizumab was 98 and 96 vs. 96 and 94% for the OKT3 group, respectively, and were not statistically different. Acute rejection rates (<6 months) were lower in the daclizumab group as compared with the OKT3 group, i.e., 5 (2.1%) vs. 16 (7.1%) (P=0.011) respectively. The incidence of infection requiring hospitalization appeared to be lower with daclizumab (7.3 vs. 16%, P<0.0036) with a similar trend with cyclomegalovirus infection, i.e., 1.6 vs. 4%, respectively (P=0.14).. The combination of daclizumab, tacrolimus, mycophenolate mofetil, and steroids is safe and effective for kidney transplant recipients in lowering the incidence of early acute rejection and without any increase in morbidity when compared to our previous protocol, which may have an eventual impact in long-term graft survival.

With improvements in surgical technique and the advent of new and more effective immunosuppressive agents, survival rates in liver transplant recipients have dramatically improved. However, hyperlipidemia frequently develops in patients administered cyclosporine-based immunosuppression long-term, although it appears to occur less often with newer, tacrolimus-based regimens. We sought to determine whether an isolated change in the baseline immunosuppressive regimen (cyclosporine to tacrolimus) would improve hyperlipidemic states in these patients. Twenty-one long-term stable liver transplant recipients with hyperlipidemia, manifested by elevated cholesterol and/or triglyceride levels, were offered conversion to tacrolimus from cyclosporine A therapy. Lipid profiles were monitored at baseline (while on cyclosporine therapy) and at 1 and 3 months after conversion to tacrolimus therapy. There were no other medication manipulations. After conversion to tacrolimus therapy, mean cholesterol levels decreased from 251 to 202 mg/dL at 1 month (P <.001) and 194 mg/dL at 3 months (P <.001). Similarly, triglyceride levels decreased from 300 to 207 mg/dL by 1 month (P =.011) and 203 mg/dL by 3 months (P <.001). There was also a statistically significant decrease for very low-density lipoprotein levels at 3 months (P =.005) and low-density lipoprotein levels at 1 and 3 months (P =.013 and P =.014, respectively). High-density lipoprotein levels did not significantly change after conversion to tacrolimus therapy. Conversion was not accompanied by adverse side effects, and patients tolerated the change well. In conclusion, simple conversion from cyclosporine to tacrolimus-based immunosuppression therapy is safe and improves posttransplantation hyperlipidemia in a subgroup of liver transplant recipients.

Since its approval as an immunosuppressive agent in renal transplantation, sirolimus (RAPA) recently has been used in the primary immunosuppression regimen at several liver transplant centers. One of the major side effects of RAPA is hypercholesterolemia, which is reported in up to 44% of patients. We describe our experience in 57 primary liver transplant recipients treated with RAPA and either cyclosporine A (CSA) or tacrolimus (TAC). We report the incidence and severity of hypercholesterolemia using a prednisone-free immunosuppressive regimen. Between January 2000 and September 2000, a total of 57 patients underwent transplantation at the University of Colorado Health Sciences Center (Denver, CO) with RAPA and either CSA or TAC. The initial 10 patients who underwent transplantation under this protocol were not administered corticosteroids, and the subsequent 47 patients were administered only 3 doses of methylprednisolone days 0, 1, and 2 postoperatively (1, 0.5, and 0.5 g, respectively). Total fasting cholesterol, high-density cholesterol, low-density cholesterol, and triglyceride levels were measured at monthly intervals. Mean serum cholesterol level was significantly greater in CSA patients (200 mg/dL) compared with TAC patients (158 mg/dL; P =.0003). Serum triglyceride levels were more than 2-fold greater with CSA (292 mg/dL) compared with TAC (134 mg/dL; P =.002). Hypercholesterolemia (cholesterol > 240 mg/dL) was present in 10 of 57 patients (18%) and was significantly more common in CSA-treated patients (8 of 27 patients; 30%) compared with TAC-treated patients (2 of 30 patients; 6%; P <.05). Hypertriglyceridemia (serum triglyceride > 300 mg/dL) was present in 10 of 57 patients (18%) and was significantly more common in CSA-treated patients (9 of 27 patients; 33%) compared with TAC-treated patients (1 of 30 patients; 3%; P <.05). We conclude that (1) concomitant use of TAC with RAPA reduces the prevalence and severity of posttransplantation dyslipidemia, and (2) these findings have important implications in the prevention of complications of hypercholesterolemia in liver transplant recipients.

Tacrolimus is a potent immunosuppressive agent that provides higher freedom from acute and chronic rejection than cyclosporine after liver transplantation (LTx). Initially, a steroid-free state was observed in about 70% of patients at 1 year; this did not change over the next 5 years. The present study identifies the various reasons why the remaining 30% of adult patients still require steroids even after 5 years after successful LTx.. Eight hundred thirty-four consecutive patients who underwent LTx between August 1989 and December 1992 were included in this study. Four hundred ninety-nine patients were alive in January 1999 and were available for this study. The dose of steroid and the reason for steroid use were retrospectively determined from the clinical records.. Three hundred sixty-five patients (73.1%) were off steroid, whereas 134 patients (26.9%) were receiving prednisone (mean dose was 6.4+/-3.7 mg/day) at the time of the study. Four hundred and eight-four patients (97%) were off prednisone at some time after LTx; however, in 119 (23.8%) patients, steroids were reintroduced. Fifteen patients (3%) continued to receive prednisone; eight receive prednisone due to reluctance of the local physician to withdraw the medication; in five patients, the prednisone was not withdrawn because these patients were on cyclosporine; in the remaining two patients, repeated attempts to withdraw steroid resulted in a rise in liver function test. In the 49 (36.6%) of 119 patients in whom the steroid was reintroduced, it was restarted secondary to pathologically proven or clinically suspected rejection (group I). In five patients steroid was reintroduced for abnormal liver function after being off immunosuppression for treatment of a posttransplantation lymphoproliferative disorder. Six patients were noncompliant with their immunosuppressive medication, and the steroid was reintroduced to control rejection. Steroids were reintroduced in 30 patients (22.4%) for recurrence of original disease: primary biliary cirrhosis (n= 19), sclerosing cholangitis (n=6), and autoimmune hepatitis (n=5) (group II). In 24 patients (20.2%), steroids were reintroduced to lower the dose of tacrolimus secondary to nephrotoxicity. Six of these patients received kidney transplantation (group III). In 16 patients (13.4%) the steroid was reintroduced for concomitant medical problems, consisting of ulcerative/Crohn's colitis (n=6), adrenal insufficiency (n=5), hematological disorders (n=3), dermatitis (n=1), and rheumatoid arthritis (n=1) (group IV).. Ninety-seven percent of patients under tacrolimus were weaned off steroid; however, 23.8% required steroid reintroduction for late rejection, recurrence of autoimmune process(es), renal impairment, or the concomitant presence of other medical conditions. Although the use of other immunosuppressive agents may reduce the rate of reintroduction of steroid, long-term sustained freedom from steroid may not be possible in all patients under tacrolimus secondary to these conditions.

Hyperlipidemia is common after cardiac transplantation and it is a risk factor for post-transplantation coronary artery disease. Immunosuppression with corticosteroids and cyclosporine has been associated with hyperlipidemia. Pravastatin, a HMG-CoA reductase inhibitor, has been shown to be effective and safe for cholesterol reduction in adult heart transplant recipients. To our knowledge the safety and efficacy of pravastatin therapy in pediatric and adolescent heart transplant populations have not been previously analyzed. Therefore, we evaluated lipid profiles, liver transaminases, rejection data, and possible side effects in pediatric and adolescent cardiac transplant recipients treated with pravastatin.. The study group consisted of 40 cardiac transplant recipients 10 to 21 years old (mean age 16.9 years). Twenty-two patients received pravastatin in addition to an immunosuppressive regimen of either cyclosporine or tacrolimus, azathioprine or mycophenolate mofetil, and prednisone. Serial determinations of total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein, and triglycerides were available for all pravastatin-treated patients. Pre-treatment lipid values and hepatic transaminases were compared with those measured after therapy with pravastatin. Comparison of pravastatin-induced lipid reduction between groups treated with cyclosporine vs tacrolimus was also made.. Patients receiving pravastatin experienced a mean 32 mg/dl decrease in TC (p < 0.005) and a mean 31 mg/dl decrease in LDL (p < 0.005), regardless of their immunosuppressive regimen. No statistical differences occurred in the magnitude of mean lipid reduction induced by pravastatin between the groups treated with cyclosporine vs tacrolimus. No significant changes in hepatic transaminase levels were noted, and no clinical evidence of pravastatin-induced myositis occurred in any subjects.. Pravastatin therapy is effective and safe when used in pediatric and adolescent cardiac transplant recipients. Although the pravastatin-induced reduction in TC and LDL was more pronounced in patients receiving cyclosporine, the reduction was not statistically different from that in the tacrolimus group. No evidence of hepatic dysfunction or rhabdomyolysis in patients treated with pravastatin was noted. Long-term studies are required to evaluate the effect of pravastatin therapy on the incidence of accelerated coronary atherosclerosis in this population.

Hypertension and hyperlipidemia are more prevalent after liver transplantation with cyclosporine as the primary immunosuppressive agent compared with tacrolimus. To determine whether blood pressure, serum lipid level, or weight improves when patients switch immunosuppression therapy, we retrospectively studied 26 liver transplant recipients with stable graft function who had been converted from cyclosporine to tacrolimus therapy with a median follow-up of 8 months. One of the 26 patients developed pruritus necessitating withdrawal of tacrolimus. The results therefore concern the remaining 25 patients. With the exception of a small decrease in bilirubin level (P <.05), there was no difference in graft or renal function after conversion. Mean systolic blood pressure decreased from 158 +/- 25 to 148 +/- 22 mm Hg over a mean of 8 +/- 3 months after conversion to tacrolimus (P =.015), whereas mean serum cholesterol level decreased from 5.3 +/- 0.9 to 4.9 +/- 0.9 mmol/L (P =.01). Sixty-eight percent of the patients lost weight, from a mean of 79.4 +/- 22.6 to 76.1 +/- 20.1 kg, in the 11 months after switching to tacrolimus therapy (P =.024). Serum triglyceride and blood glucose levels did not change, and no patient developed diabetes mellitus after conversion. These results indicate that switching from cyclosporine to tacrolimus can reduce blood pressure, serum cholesterol level, and weight after liver transplantation.

Corticosteroids have been a cornerstone of immunosuppression for four decades despite their adverse side effects. Past attempts at steroid withdrawal in pediatric renal transplantation have had little success. This study tests the hypothesis that a complete steroid-free immunosuppressive protocol avoids steroid dependency for suppression of the immune response with its accompanying risk of acute rejection on steroid withdrawal.. An open labeled prospective study of complete steroid avoidance immunosuppressive protocol was undertaken in 10 unsensitized pediatric recipients (ages 5-21 years; mean 14.4 years) of first renal allografts. Steroids were substituted with extended daclizumab use, in combination with tacrolimus and mycophenolate mofetil. Protocol biopsies were performed in the steroid-free group at 0, 1, 3, 6, and 12 months posttransplantation. Clinical outcomes were compared to a steroid-based group of 37 matched historical controls.. Graft and patient survival was 100% in both groups. Clinical acute rejection was absent in the steroid-free group at a mean follow-up time of 9 months (range 3-13.7 months). Protocol biopsies in the steroid-free group (includes 10 patients at 3 months, 7 at 6 months, and 4 at 12 months) revealed only two instances of mild (Banff 1A) subclinical rejection (reversed by only a nominal increase in immunosuppression) and no chronic rejection. At 6 months the steroid-free group had no hypertension requiring treatment (P=0.003), no hypercholesterolemia (P=0.007), and essentially no body disfigurement (P=0.0001). Serum creatinines, Schwartz GFR, and mean delta height Z scores trended better in the steroid-free group. In the steroid-free group, one patient had cytomegalovirus disease at 1 month and three had easily treated herpes simplex stomatitis, but with no significant increase in bacterial infections or rehospitalizations over the steroid-based group. The steroid-free group was more anemic early posttransplantation (P=0.004), suggesting an early role of steroids in erythrogenesis; erythropoietin use normalized hematocrits by 6 months.. Complete steroid-free immunosuppression is efficacious and safe in this selected group of children with no early clinical acute rejection episodes. This protocol avoids the morbid side effects of steroids without increasing infection, and may play a future critical role in avoiding noncompliance, although optimizing renal function and growth.

To improve long-term outcome after renal transplantation, attention should be placed on the tailored use of immunosuppressive regimens that have a more favorable impact on the immunological and nonimmunological risk profiles of an individual recipient. Tacrolimus is widely used for maintenance and rejection immunosuppression in solid organ transplantation, and compared with cyclosporine, its use in renal transplantation is associated with a reduced incidence and severity of acute rejection and a more positive effect on known cardiovascular risk factors. Recent experience with tacrolimus-based therapy has demonstrated an improved lipid profile and lower arterial blood pressure, with less requirement for lipid-lowering and antihypertensive medication compared with cyclosporine, without significantly increasing the risk of long-term insulin-dependent posttransplant diabetes mellitus. The advantageous effects of tacrolimus on both immunological and nonimmunological risk factors offer potential benefits for long-term graft function and survival.

The role of hyperlipidemia in graft coronary artery disease (GCAD) is controversial although hyper-triglyceridemia is an independent risk factor. Recent studies show that 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) inhibitors decrease the incidence of GCAD in adults. The incidence of GCAD in pediatric patients is lower than in adults; it is not clear whether age-related differences in lipid metabolism account for some of this protection. This study was performed to: characterize the lipoprotein profile in children after heart transplantation; demonstrate that total cholesterol (TC) is a poor marker for underlying lipoprotein abnormalities; and to compare lipid abnormalities in patients who had been converted from cyclosporin A (CsA) to tacrolimus. Seventy-one determinations of fasting lipoprotein profiles were performed in a cohort of 28 children. Each child had at least two determinations on separate occasions. TC, low-density lipoprotein (LDL), and serum triglyceride (TG) levels were categorized as abnormal if greater than the 75th percentile for age and gender. A high-density lipoprotein (HDL) level less than the 25th percentile was considered abnormal. Immunosuppression included CsA or tacrolimus, azathioprine, and prednisone. We found that 90% of the patients studied had abnormalities of either TG or HDL. In contrast, LDL tended to be normal when adjusted for age and gender. TC was a poor indicator of any underlying abnormality in TG, LDL, or HDL. In patients converted to tacrolimus, no significant differences were found in the levels of TG, LDL or HDL compared with each patient's respective values while receiving CsA. Hence, lipoprotein abnormalities among pediatric heart transplant recipients are highly prevalent. TC is a poor screening tool in the evaluation for lipid abnormalities. Lipoprotein profiles remain statistically unchanged after conversion from CsA to tacrolimus.

Cyclosporine (CsA)-associated side effects include nephrotoxicity, hypertension, neurological disorders, and hyperlipidemia. A considerable share of early and long-term posttransplant morbidity is likely to be drug related.. In 31 patients with stable graft function, conversion from CsA to tacrolimus was implemented due to nephrotoxicity (n=19), hypertension (n=9), and neurological disorders (n=8).. Three months after conversion, a response was evident in 26 patients (84%), whereas 5 patients (16%) were nonresponsive. In 13 of 19 patients (68%) suffering from nephrotoxicity, serum creatinine levels decreased significantly from 2.0+/-0.5 mg/dl to 1.5+/-0.4 mg/dl (P<0.005), whereas in 6 of 19 patients (32%) no improvement was observed. Antihypertensive therapy was reduced in six of nine patients and neurological disorders improved in six of eight patients. When analyzing all patients, average levels of cholesterol and triglycerides were significantly lower after conversion when compared with at the time of conversion (P<0.05). Conversion to tacrolimus reduced drug-related side effects in the majority of patients, while graft function remained stable. Conversion to tacrolimus may be considered for CsA-related side effects as a potential beneficial approach.

We studied rejection, allograft function and side effects, such as hypertension, renal dysfunction and hypercholesterolemia, in seven patients switched from cyclosporine-based triple-drug immunosuppression to FK 506.. A subset of pediatric heart transplant recipients treated with triple-drug immunosuppression consisting of cyclosporine, azathioprine and prednisone experience either persistent rejection when attempts are made to taper corticosteroids or morbidity from cyclosporine and corticosteroids. Experience with the new immunosuppressive agent FK 506 has demonstrated its effectiveness as a single agent in heart transplant recipients, and anecdotal evidence has shown that side effects such as hypertension and hypercholesterolemia may be lower.. Seven patients whom we deemed corticosteroid dependent were switched to FK 506-based therapy. Allograft function, episodes of rejection, need for corticosteroids and incidence of side effects from FK 506 were monitored. The switch to FK 506 was performed using an established protocol. Follow-up time has ranged from 15 to 41 months. Serial right heart catheterizations and endomyocardial biopsies were performed after each reduction of corticosteroid dosing.. Catheterization data showed no significant change in pulmonary wedge pressure, mean right atrial pressure or cardiac index, indicating no decline in allograft function. Serial echocardiographic variables of allograft function were also stable. At present, all seven patients are free of the corticosteroid portion of their immune suppression. There have been only two episodes of significant acute rejection requiring treatment with intravenous corticosteroids. Antihypertensive medications have been discontinued in five of six patients previously treated with these drugs. Plasma cholesterol, low density lipoprotein and triglyceride levels were decreased, and renal function was stable.. Preliminary studies suggest that FK 506 may be an alternative immunosuppressive agent for pediatric and adolescent patients experiencing ongoing rejection or significant morbidity from cyclosporine and corticosteroids and in those patients dependent on corticosteroids for immune suppression.
