Biomarker assessment of the immunomodulator effect of atorvastatin in stable renal transplant recipients and hypercholesterolemic patients.
    Molecular diagnosis & therapy, 2010, Dec-01, Volume: 14, Issue:6

    HMG-CoA reductase inhibitors (statins) have effects beyond lipid lowering, including immunomodulatory and anti-inflammatory properties. Statins are frequently combined with immunosuppressive agents in transplant recipients to modulate the hyperlipidemic side effects of the immunosuppressants. However, the role of statins in the immunosuppressive response that is achieved in individual patients remains to be assessed.. The aim of this study was to evaluate the immunomodulatory effect of atorvastatin given alone and in combined treatment with tacrolimus and mycophenolate mofetil.. Two patient groups were studied: renal transplant recipients receiving tacrolimus and mycophenolate mofetil therapy, and hypercholesterolemic patients (the control group). Fasting blood samples were taken from participants before and 1 month after atorvastatin treatment was started to study a small battery of biomarkers that are able to reflect the range of the effects of immunosuppressive therapy and atorvastatin.. All patients in the study were enrolled at the Hospital Clinic of Barcelona.. All patients enrolled in the study were candidates for treatment with atorvastatin because of high cholesterol levels. One group consisted of 25 stable renal transplant recipients with low-density lipoprotein (LDL) cholesterol levels above 100 mg/dL after 3 months of therapeutic lifestyle changes, according to the guidelines of the National Kidney Foundation - Kidney Disease Outcomes Quality Initiative. The other group included 25 hypercholesterolemic patients with LDL cholesterol levels above target values for the patients' overall risk, as derived from the National Cholesterol Education Program Adult Treatment Panel III criteria.. Atorvastatin (Lipitor®) treatment was started at a fixed dose of 20 mg daily.. The studied biomarkers were lymphocyte proliferation, intracellular adenosine triphosphate (ATP) synthesis in CD4+ T cells, intralymphocytary cytokine expression (interleukin [IL]-2, interferon [IFN]-γ), soluble cytokine production (IL-2, IFN-γ, IL-10, IL-17, and transforming growth factor-β) and regulatory T (T(reg)) cells.. Atorvastatin proved to be an immunomodulatory agent, significantly decreasing lymphocyte proliferation by 15% (p = 0.001), increasing ATP levels by 16% (p = 0.0004), and showing a trend toward increasing T(reg) cells in hypercholesterolemic patients (p = 0.09). In the renal transplant recipients, atorvastatin therapy did not modify any of the biomarkers of immunosuppression that were studied.. Atorvastatin showed immunoregulatory effects on T cells in hypercholesterolemic patients. These effects were absent in renal transplant recipients, suggesting that the beneficial effects of atorvastatin in this patient group do not relate to immunoregulation. Therefore, statin treatment cannot be considered as a means to reduce the dose of immunosuppressive agents.

Lipid metabolism in renal transplant patients receiving tacrolimus/sirolimus combination therapy.
    Transplantation proceedings, 2005, Volume: 37, Issue:4

    The administration of sirolimus has been reported to be associated with high serum cholesterol and high triglyceride values. In a large prospective, multicenter 6-month study in renal transplantation, basic parameters of lipid metabolism (total serum cholesterol and triglycerides) were systematically assessed in patients who received tacrolimus/mycophenolate mofetil/steroids (Tac/MMF), tacrolimus/0.5 mg sirolimus (SIR)/steroids (Tac/0.5SIR) on tacrolimus/2 mg sirolimus/steroids (Tac/2SIR).. For purposes of analysis, lipid parameters were classified using the National Kidney Foundation Dyslipidemia Classification definitions.. Complete sets of data at all visits (baseline, months 1, 3, and 6) were available for 211 Tac/MMF, 210 Tac/0.5SIR, and 203 Tac/2SIR patients. Total serum cholesterol in the Tac/MMF group was 193.4 at baseline and 202.9 mg/dL at month 6. Values increased from 196 mg/dL to 212.5 mg/dL in Tac/0.5SIR and from 200 mg/dL to 230.5 mg/dL in Tac/2SIR. Differences in parameters between treatment groups were statistically significant (P < .05). Serum triglycerides decreased from baseline to 6 months in Tac/MMF, increased from 176.3 mg/dL (baseline) to 191.4 mg/dL (6 months) in Tac/0.5SIR and from 203 mg/dL to 255.3 mg/dL in Tac/2SIR. Parameters differed significantly between Tac/0.5SIR versus Tac/2SIR at P = .0069, and between Tac/MMF versus Tac/2SIR at P = .0013. In the Tac/2SIR group 36.5% had "high" serum cholesterol and 8.3% had "very high" triglyceride levels at 6 months.. Total serum cholesterol levels were relatively stable and serum triglycerides decreased between baseline and month 6 using a Tac/MMF regimen. Contrastingly, the Tac/SIR combinations led to increased total cholesterol values (at both sirolimus dose levels) and Tac/2SIR also led to increased triglyceride levels.

Correlation between lipid abnormalities and immunosuppressive therapy in renal transplant recipients with stable renal function.
    International urology and nephrology, 2008, Volume: 40, Issue:2

    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.

Relation of C-2 monitoring with serum lipid profile in stable renal transplant patients.
    Transplantation proceedings, 2006, Volume: 38, Issue:2

    C-2 monitoring has been proposed as a more effective strategy than C-0 to predict the risk of acute rejection in the early stages posttransplantation. However, cyclosporine (CsA) is associated with posttransplant dyslipidemia. The aim of this retrospective study was to evaluate the correlations of C-0 and C-2 levels with atherogenic risk factors in the first 6 months versus after 6 months posttransplantation. We evaluated the data from 127 stable renal transplant recipients (89 males, 38 females) of mean age 38.10 +/- 12.79 years who received Neoral-based immunosuppression to investigate the relation of C-2 levels to serum lipid profile compared with C-0 values in the early and late posttransplantation periods. Receiver operating characteristic (ROC) analyses were performed to define a C-2 cutoff level that identified subjects with hypercholesterolemia, defined as a total cholesterol (TC) >200 mg/dL. There were significant positive correlations between both C-0 and C-2 levels and TC as well as the ratio of total cholesterol/HDL cholesterol (TC/HDL) in the late period. When the C-2 levels in the late posttransplantation period were stratified, serum TC concentrations showed statistically significant differences between the groups. Whole blood C-2 levels above 850 ng/mL were associated with increased serum TC concentrations; the C-2 cutoff level leading to hypercholesterolemia was 888 ng/mL. Maintenance immunosuppressive therapy under the proposed whole blood C-2 level of 888 ng/mL seemed to preserve graft function while preventing atherogenic risks for cardiovascular diseases in the late posttransplantation period.
