mycophenolic-acid 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.

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.

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.

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.

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.

De novo sirolimus in calcineurin inhibitor-free regimens, although potentially useful to improve early renal function, are complicated by various drug-related side effects.. We report a prospective open-label, multicenter, randomized trial to evaluate early conversion from a CsA-based to a sirolimus (SRL)-based regimen 10 to 24 days after renal transplantation. Of the 196 patients, 141 patients with a low-to-moderate immunological risk were eligible to be converted to SRL or to continue CsA. All patients received antithymocyte globulin-F single-bolus induction, mycophenolate mofetil, and steroids.. The primary endpoint, renal function determined by S-creatinine and estimated glomerular filtration rate calculated by Nankivell formula at 12 months was significantly better in the SRL group (1.51+/-0.59 vs. 1.87+/-0.98 mg/dL or 64.5+/-25.2 vs. 53.4+/-18.0 mL/min/1.73 m). Patient survival, graft survival, and incidence of biopsy-proven acute rejection after conversion were not statistically different. Drug discontinuations were significantly higher in the SRL group (36.2% vs. 19.7%). Significantly, more patients in the SRL group reported acne, aphtous, and temporary hyperlipidemia, whereas cytomegalovirus viremia was significantly decreased (7.3% vs. 28.2%).. Early conversion to a calcineurin inhibitor-free regimen with SRL in combination with mycophenolate mofetil may be a useful strategy to improve renal function. The identification of appropriate candidates and safe management of SRL-related adverse events will be a key to avoid the high rate of dropouts, which currently limit the broad applicability of this protocol.

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.

Hepatic multidrug resistance-associated protein 2 (Mrp2) is responsible for the majority of the biliary elimination of endogenous and exogenous substances, therefore it is important to evaluate possible functional changes in Mrp2 activity under conditions of hyperlipidemia (HL). Thus, the present study assessed the protein expression and transporting activity of hepatic Mrp2 based on the in vivo biliary excretion of phenolsulfonphthalein (PSP) as a model anionic substrate for Mrp2 in poloxamer 407-induced hyperlipidemic rats (HL rats) and compared these values with those for control rats. The pharmacokinetics of mycophenolic acid (MPA) and mycophenolic acid-7-O-glucuronide (MPAG) were evaluated after the intravenous (5 mg/kg) and oral (10 mg/kg) administration of MPA to control and HL rats. In HL rats, the protein expression of hepatic Mrp2 and its biliary transporting activity exhibited significant reductions (by 24.3% and 24.6%, respectively) in the absence of a change in bile flow rate. Unexpectedly, HL and control rats showed comparable biliary excretion rates of MPAG due to the counter effects of the reduced expression and activity of Mrp2 and a 484% increase in the free fraction of MPAG in HL rats. The estimated biliary clearance value of free MPAG in HL rats was considerably slower (by 77.1%) than that in control rats. Although significant pharmacokinetic changes in total MPA and MPAG levels were not observed in HL rats, there was a marked increase in free MPA and MPAG levels. Clinically relevant pharmacokinetic changes in subjects with HL that are related to MRP2 could not be ruled out. Copyright © 2016 John Wiley & Sons, Ltd.

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.

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.

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.

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.
