INTRODUCTION: Sirolimus (SRL) is an immunosuppressive agent of potential benefit in clinical liver transplantation (LTX). One of the major side effects of SRL is hyperlipidemia, which is reported in up to 44% of patients. In this report, we describe the lipid profiles of 20 stable liver transplant recipients who received SRL for immunosuppression. METHODS: The study group received SRL in combination with tacrolimus and/or mycophenolate mofetil (MMF). The control group was administered calcineurin inhibitor (CI) and MMF. Fasting serum cholesterol level, high-density lipoproteins (HDL) and low-density lipoproteins (LDL) were measured regularly. Furthermore, the total cholesterol/HDL ratio and the LDL/HDL ratio were evaluated. Diabetes and hypertension were monitored as well. RESULTS: In the SRL group, hypercholesterolemia was found in three patients (15%) and hypertriglyceridemia in two patients (10%). There was no marked difference from the control group, although a higher association of SRL with hyperlipidemia was described in the literature. Furthermore, HDL and LDL levels were similar in both groups, as well as total cholesterol/HDL ratio and LDL/HDL ratio. Diabetes and hypertension had a similar incidence in both the groups. Thus, there was no difference concerning the cardiovascular atherosclerosis risk between the immunosuppressive protocol with SRL or with CI. DISCUSSION: The results of our retrospective study demonstrated that the immunosuppressive regimen can potentially influence the incidence of hyperlipidemia in patients after LTX. SRL in combination with tacrolimus and/or MMF had no higher incidence of hyperlipidemia than CI and MMF. The combination of immunosuppressive therapy with low dose and low levels of each immunosuppressive agent could decrease the risk of atherosclerosis and its complications in long-term survivors after LTX. 相似文献

Mycophenolate mofetil (MMF) is a potent immunosuppressive agent used to prevent acute and chronic rejection in kidney transplantation or for rescue therapy. One side effect of MMF is bone marrow toxicity, including leukopenia, which may necessitate drug withdrawal. We report 2 patients who underwent kidney transplantation and developed leukopenia while receiving MMF and safely switched to sirolimus. A 35-year-old woman underwent deceased donor kidney transplantation. She received basiliximab, tacrolimus, MMF, and a corticosteroid. On postoperative day (POD) 75, her white blood cell (WBC) count was 1800/μL. A 44-year-old women underwent deceased donor kidney transplantation and received basiliximab, tacrolimus, MMF, valganciclovir, and a corticosteroid. On POD 88, her WBC count was 1320/μL. MMF was switched to sirolimus, resulting in recovery of WBC count without rejection. Switch from MMF to sirolimus is safe and favorable in MMF-induced leukopenia in renal transplant recipient. 相似文献

Chronic renal failure triggered by calcineurin inhibitor (CNI)-based immunosuppression is a common complication after cardiac transplantation. Sirolimus and mycophenolate mofetil (MMF) are 2 newer immunosuppressive agents with no documented nephrotoxic side effects. This case report describes a patient with ongoing chronic renal failure 10 months after cardiac transplantation on cyclosporine-based immunosuppressive therapy. Conversion of the immunosuppressive regimen from cyclosporine to sirolimus and MMF resulted in freedom from acute rejection, excellent cardiac graft function and consistently improved renal function. This case illustrates the beneficial potential of sirolimus and MMF as CNI-free and safe long-term immunosuppression in a patient with chronic renal failure after heart transplantation. 相似文献

Sirolimus (SRL) provides effective immunosuppression for kidney transplantation and may be useful in patients with delayed allograft function after kidney transplantation. We review our experience with SRL in liver transplant recipients for whom calcineurin inhibitors are undesirable. Fourteen patients with renal insufficiency or acute mental status impairment were administered SRL after liver transplantation (5- to 10-mg load, 1 to 4 mg/d). Immunosuppression also consisted of mycophenolate mofetil and corticosteroids. On resolution of neurological or renal dysfunction (return to baseline mental status or serum creatinine level), tacrolimus (TAC) therapy was initiated. Twelve patients received primary transplants, 1 patient received a combined liver-kidney transplant, and 1 patient received a third transplant. Follow-up was 2 to 7 months. Calcineurin inhibitors were initially withheld in 9 patients, and therapy was aborted because of toxicity in the remaining 5 patients. Mean times to the initiation of SRL and TAC therapy were 5.4 ± 4.6 and 26.8 ± 24.4 days, respectively. Serum trough levels of SRL did not correlate with dose or other patient variables. Two patients died after prolonged pretransplantation hospital courses in the intensive care unit. Six patients experienced acute rejection, but only 1 patient required antilymphocyte therapy. Serum creatinine levels at the start of SRL therapy were 2.2 ± 1.1 and 1.2 ± 0.6 mg/dL at 3 months. All 3 patients with neurological indications for SRL had a return to their baseline mental status. All patients had improved liver function chemistry test results and prothrombin times. No patients developed leukopenia or thrombocytopenia. SRL is safe after liver transplantation in patients with acute neurological or renal impairment. SRL is an attractive alternative when calcineurin inhibitors are undesirable, but serum trough levels of SRL should be monitored. A prospective randomized study of an SRL-based calcineurin inhibitor–avoiding regimen compared with standard therapy in patients with renal insufficiency will further evaluate the role for SRL in liver transplantation.

Abstract: Liver transplantation (LTX) today has become a routine procedure granting curative treatment for various hepatic diseases with excellent survival rates. Constant improvement of immuno-suppressive regimens has led to significant reduction of rejection frequency and increased safety in long-term management. Calcineurin-inhibitors play the key role in most immunosuppressive protocols providing strong T-cell suppression yet often associated with numerous side-effects. Increasing renal insufficiency as well as hypertension, hyperglycaemia, hyperuricaemia, and increased risk of secondary malignancy account for the major problems in short- and long-term follow-up of LTX patients. Mycophenolate mofetil (MMF) as a purine-synthesis inhibitor has proved to be a potent immunosuppressive agent largely free of the CI-associated side-effects. MMF therefore has been used to modulate immunosuppressive protocols in order to both increase efficacy and to reduce CI-related side-effects such as nephrotoxicity. In recent years, MMF-monotherapy protocols have been suggested for LTX patients with renal insufficiency. This review provides an overview on the current role of MMF in immunosuppressive protocols after LTX and evaluates innovative therapeutic concepts. 相似文献

Influence of Co-Medication with Sirolimus or Cyclosporine on Mycophenolic Acid Pharmacokinetics in Kidney Transplantation 总被引:1,自引:0,他引:1

The pharmacokinetics of mycophenolic acid (MPA)--the active metabolite of mycophenolate mofetil (MMF)--is significantly influenced by co-medications. The impact of sirolimus on daily MPA exposure, however, has not been investigated so far. As a part of the study aimed at investigating the efficacy of Campath-1H induction therapy in a steroid-free regimen in kidney transplantation, MPA plasma levels were serially measured in 21 patients treated with low-dose sirolimus (SRL) or low-dose CsA both in addition to low-dose MMF over 12 months post-operatively. Full pharmacokinetic profiles were compared at month 6 and 12 post-surgery. Mean dose-adjusted MPA trough levels were 4.4-fold higher in patients on combined SRL and MMF than in those given CsA and MMF. Pharmacokinetic studies demonstrated that mean MPA C(max) and T(max) were comparable in the two groups, while mean MPA AUC(0-12) was higher in SRL than CsA treated patients. The pharmacokinetic profile of SRL- but not of CsA-group showed a second peak consistent with the enterohepatic recirculation of MPA. These findings suggest that SRL and CsA have different effects on MPA metabolism and/or excretion eventually affecting its immunosuppressive property and/or toxicity. CsA, but not SRL, inhibits MPA enterohepatic recirculation, reducing MPA daily exposure. 相似文献

Calcineurin-inhibitor-sparing immunosuppressive protocols 总被引:3,自引:0,他引:3
Calcineurin inhibitors (CNI) have played an important role in improving graft survival. However, the balance between preventing immunologic allograft losses and the management of CNI-related nephrotoxicity is still an issue in renal transplantation. There are three major CNI-sparing strategies. CNI MINIMIZATION: The advent of mycophenolate mofetil (MMF) allows cyclosporine (CsA) reduction to ameliorate renal function in patients with chronic renal allograft dysfunction, without increasing acute rejection rates. In combination with mTOR inhibitors, very low CNI levels may be sufficient to prevent acute rejection. However, in this association, CNI nephrotoxicity is magnified by pharmacokinetic interaction. CNI WITHDRAWAL: CNI withdrawal has been attempted in regimens containing MMF or sirolimus (SRL). Introduction of MMF in patients with chronic allograft nephropathy (CAN) followed by CNI withdrawal resulted in stabilization or improvement of renal function and hypertension profile, although there is some risk of acute rejection. In regimes based on SRL, CNI withdrawal is a safety strategy, achieving a sustained improvement of renal function, histology, and graft survival. There is not consensus at all whether MMF should be added or not in patients converted from CNI to mTOR inhibitor. CNI AVOIDANCE: Polyclonal-based regimens with MMF and steroids have shown acceptable acute rejection rates, but high rates of cytomegalovirus (CMV) and opportunistic infections. Conversely, anti-IL-2R in combination with MMF and steroids resulted in 50% incidence of acute rejection, thus suggesting that CNI avoidance is not feasible in a regimen based on MMF. Alternatively, a protocol based on anti-IL-2R induction therapy combined with SRL, MMF, and prednisone has shown an efficient prevention of acute rejection, higher creatinine clearance and lower rate of CAN in comparison with a group treated with CNI. New strategies using costimulation blockade may help in the development of safe CNI-free regimens. In summary, in renal transplantation the new immunosuppressive medications have made feasible old aspirations such as minimization, withdrawal, or even avoidance of CNI. 相似文献

In addition to an analysis of the final results of phase I/II and phase III clinical trials of sirolimus (SRL), this review focuses on the recent results of several studies in renal transplantation, which include diverse combinations of SRL with other immunosuppressive agents. While SRL was initially introduced as an adjunctive agent to calcineurin inhibitors, it is now serving as the base for therapies that spare or avoid these nephrotoxic drugs. However, to optimize the use of SRL as base therapy, further work is necessary to determine target concentrations, requirement for concomitant steroids and/or nucleoside synthesis blockers, and countermeasure therapy to overcome the drug's adverse effects. 相似文献

BACKGROUND: It is not known how different steroid-free immunosuppressive combinations affect long-term kidney transplant function in recipients of simultaneous kidney and pancreas transplant (SPK). Here, we sought to evaluate, in SPK recipients, the impact on long-term renal allograft function of two Tac-based prednisone-free maintenance immunosuppressive protocols: tacrolimus (Tac)/mycophonelate mofetil (MMF) versus Tac/ sirolimus (SRL). METHODS: In this single-center, retrospective, sequential study, we analyzed 59 SPK transplant patients with at median follow up of 5 years. All patients received induction therapy with thymoglobulin and maintenance immunosuppression with Tac/MMF (n=22) or Tac/SRL (n=37). There were no differences between the two groups in regards to age, gender, race, panel reactive antibodies, degree of mismatch, donor age, incidence of delay graft function, and Tac trough levels at different time points after transplantation. RESULTS: Kaplan-Meier patient survival at 6 years after transplantation was not statistically different between the two groups. Rate of ACR was similar. Kidney survival, even if not statistically significant, was better in the Tac/MMF group than in the Tac/SRL (90.7% vs. 70.7%, P=0.09). The slope of glomerular filtration rate decline per month at 5 years after transplantation was not statistically different between the two groups. Both groups had the same decline over time in glomerular filtration rate of 0.40+/-0.06 mL/min/1.73/month. Pancreas survival at 6 years after transplantation was 100% in both treatment groups. CONCLUSIONS: Our data suggest that, in SPK recipients, long-term kidney allograft survival and function are not statistically different. A trend toward an increased rate of renal allograft loss was found in the Tac/SRL-treated group. 相似文献

Sirolimus: a potent new immunosuppressant for liver transplantation 总被引:17,自引:0,他引:17

BACKGROUND: Sirolimus (rapamycin) is a new immunosuppressant that appears to be synergistic with cyclosporine in kidney transplantation, but with a different side-effect profile. This pilot study evaluated sirolimus in liver transplantation. METHODS: Patients undergoing orthotopic liver transplantation for primary tumors (8), and later for nonmalignant disease (7), received one of three sirolimus-based immunosuppressive regimens. Protocol A comprised sirolimus, microemulsion cyclosporine (target whole blood concentration: 100 ng/ml), and prednisolone; protocol B omitted prednisolone; and protocol C was sirolimus alone. By 3 months after transplantation, all patients were receiving sirolimus as monotherapy. RESULTS: Fifteen patients were treated with a follow-up of 117-806 days. Rejection was more common on monotherapy than double therapy, and absent on triple therapy. The drug was generally well tolerated, with only three patients discontinuing sirolimus: one for hyperlipidemia, one for pneumocystis pneumonia, and one for inability to tolerate the taste of the drug. Two patients discontinued cyclosporine early, both as a result of neurological complications; they continued on sirolimus monotherapy. Five patients died; one suffered a cardiac arrest, and four died from sepsis in association with graft-versus-host disease, recurrent tumor, a paralyzed right hemidiaphragm, and primary nonfunction. CONCLUSIONS: Sirolimus combined with cyclosporine provided potent immunosuppression of liver allografts, and sirolimus monotherapy was adequate and well tolerated as maintenance therapy. Side effects of sirolimus over the short period of follow-up were uncommon and reversible with dose reduction or cessation of therapy. 相似文献

AIMS: Chronic allograft nephropathy and/or calcineurin inhibitor toxicity are common problems after organ transplantation. The aim of this study was to examine the safety and efficacy of switching from a calcineurin inhibitor-based to a calcineurin inhibitor-free immunosuppressive regimen consisting of sirolimus and mycophenolate mofetil (MMF) late after renal transplantation. METHODS: Kidney biopsies were performed in renal-transplanted patients with increasing serum creatinine levels at least 6 months after transplantation (mean time +/- SD after renal transplantation: 76.4 +/- 50.4 months). Patients with no signs of acute rejection were switched to MMF (500-2,000 mg/day) in combination with a low dose of sirolimus (1 mg/day). Renal function, serum chemistry, blood trough levels of sirolimus and MMF, and blood pressure were monitored. RESULTS: 13 patients were investigated. During our observation period (mean observation time +/- SD: 11.2 +/- 5.9 months), an improvement in renal function was observed in 10/13 patients. In 3/13 patients, renal function deteriorated further and hemodialysis was initiated in 2 patients within the next 6 months. However, a serum creatinine concentration above 3.5 mg/dl was measured in 2 of those 3 patients prior to the switch of the immunosuppressive protocol. Administration of a low dosis of sirolimus (1 mg/day) led to relevant sirolimus (4.16 +/- 1.85 ng/ml) and MMF blood trough levels (month 1: 6.8 +/- 3.46; month 3: 4.67 +/- 1.78 mg/l). The following adverse events were observed: borderline acute rejection (1/11 patients), anemia responding to higher dosage of erythropoietin (3/11), hyperlipidemia (1/11), and urinary tract infections (4/11). CONCLUSIONS: Low-dose sirolimus therapy in combination with concentration-adjusted MMF therapy leads to improvement of organ function late after renal transplantation. The follow-up of those patients should include assessments of blood cell counts, serum lipids and urinalysis to recognize the possible side effects. 相似文献

Despite their contribution in the success of organ transplantation, calcineurin inhibitors (CNIs) may be responsible for frequent and severe side effects that can affect graft survival and life expectancy. In this article, we have reviewed registry studies and randomized controlled trials (RCTs) that seek to avoid, withdraw, or minimize CNIs in renal transplant recipients. Attempts to completely avoid CNIs by administering mycophenolate mofetil (MMF) and/or sirolimus (SRL) have resulted in increased risks of rejection and side effects, with small advantage to improve renal graft function. Early withdrawal of CNIs after transplantation using administration of MMF can improve graft function but may be associated with a greater risk of acute or chronic rejection and graft failure. RCTs in which CNIs were replaced a few months after transplantation by SRL reported improved graft function among SRL-treated patients, but such a treatment was complicated by iatrogenic toxicity. Late replacement of CNIs with SRL did not produce a particular advantage and again was complicated by more frequent side effects. On the basis of these trials, it seems that CNI elimination can trigger rejection or side effects. Recent RCTs showed that minimization of CNI doses in association with everolimus does not increase the risk of rejection, allows one to obtain good graft function, and is well tolerated. Such an approach seems therefore preferable to complete elimination of CNIs with substitution of the current immunosuppressive drugs. 相似文献

Immunosuppressants are the cornerstones of treatment after solid organ transplantation. This study investigated the pathology and cell proliferation following partial hepatectomy (PH) in rats undergoing immunosuppressive treatment. After 1 day, all rats were subjected to 70% PH. Groups A and B (n = 10) received calcineurin inhibitors subcutaneously: either FK506 or cyclosporine (CyA). Groups C and D (n = 10) received antiproliferative drugs: either mycophenolate mofetil (MMF) or sirolimus (SRL) by gavage. A control group (n = 5) received 1 mL of tap water daily. On postoperative day 2, all rats were sacrificed to obtain liver tissue for pathologic examination. Using immunohistochemistry we separately examined the hepatectomy surface and the liver parenchyma. In the parenchyma, the Ki-67 indices were higher in the CyA and FK506 groups and lower in the SRL and MMF groups compared with controls (P < .01). CyA had the highest and MMF the lowest values. On the hepatectomy surface, Ki-67 indices and TGF-alpha expressions were higher in the CyA group and lower in the SRL and MMF groups compared with the control group (P < .01). Slightly higher values in the FK506 group were not significantly different compared with the control group (P > .05). All groups other than FK506 showed prominent cholangiolar epithelial phenotypes compared with the control group. In the CyA and SRL groups, the number of cholangiolar cells was higher (P < .01), and in the MMF group lower than in the control group (P < .01). Among all groups, SRL had the highest values. 相似文献

Renal transplantation is the best therapeutic option for patients with end-stage renal disease. Although short-term results are excellent, long-term graft survival has not improved substantially in recent times. Chronic allograft nephropathy (CAN) and death with a functioning graft are the most important causes of graft loss. Recent evidence shows that nephrotoxicity of calcineurin inhibitors contributes to CAN, and the introduction of non-nephrotoxic drugs such as mycophenolate mofetil (MMF) and mammalian target of rapamycin inhibitors may provide new immunosuppressive strategies to improve long-term results after renal transplantation. MMF decreases the risk of developing chronic allograft failure and is useful for treating established CAN, because it has a beneficial effect on allograft fibrosis. Treatment with sirolimus (SRL), a basic immunosuppressive drug given in association with MMF, may offer better renal function, decrease the prevalence of CAN, and downregulate expression of genes responsible for the progression of CAN than treatment with cyclosporine A (CsA). SRL also permits an early elimination of CsA from SRL-CsA-steroid regimens and shows better renal function and improved renal histology without risk of rejection. Notably, this approach improves graft survival at 4 years. Further multicenter studies are needed to determine whether both approaches produce similar results by comparing immunosuppression caused by SRL-based and tacrolimus (TAC)-based treatments. Because TAC is the most commonly used anticalcineurin drug, it is important to compare the effects of steroid-TAC-SRL treatment with and without elimination of TAC. Finally, although caution is needed, the use of non-nephrotoxic immunosuppressive treatment may change the natural history of CAN. 相似文献

BACKGROUND: Chronic steroid therapy in kidney transplantation has myriad side effects and steroid avoidance has become feasible. This prospective study compared the safety and efficacy of steroid avoidance in tacrolimus (TAC)/mycophenolate mofetil (MMF) and TAC/sirolimus (SRL) combinations in kidney transplantation. METHODS: In all, 150 kidney recipients were analyzed: 75 each in TAC/MMF and TAC/SRL groups. The primary endpoint was acute rejection. Surveillance biopsies were completed to analyze subclinical acute rejection (SCAR) and chronic allograft nephropathy (CAN). Acute rejection and SCAR were treated by methylprednisolone. Two-year patient and graft survival, renal function, and adverse effects were monitored. RESULTS: Acute rejection was seen in 12% of TAC/MMF and 8% of TAC/SRL patients. Two-year actuarial patient survival was 95% and 97%, and graft survival 90% and 90% in TAC/MMF and TAC/SRL groups, respectively. Surveillance biopsy showed cumulative incidence of SCAR was 27 % in TAC/MMF and 16 % in TAC/SRL groups at 2 years (P = 0.04). Overall, 33% of recipients in TAC/MMF and 20% in TAC/SRL received methylprednisolone for acute rejection/SCAR. Moderate/severe CAN was 10% in TAC/SRL group and 22% in TAC/MMF group(P = 0.06). New-onset diabetes mellitus (NODM) was 4% each in both groups. All recipients remain free of maintenance steroid therapy. CONCLUSIONS: Steroid avoidance in tacrolimus-based immunosuppression with MMF or SRL provides equivalent 2-year patient and graft survival with a low incidence of acute rejection and NODM. SCAR and CAN are lower in TAC/SRL compared to TAC/MMF group. The impact of decreased SCAR and CAN in TAC/SRL group on longer-term graft survival and function is to be evaluated. 相似文献

Lymphocele is a complication of renal transplantation, representing a lymphatic collection around the grafted kidney. The use of the immunosuppressive agent sirolimus (SRL) has been associated with a significant increase in lymphocele formation. This complication has been related to the antiproliferative activity of SRL, which delays surgical wound repair and closure of injured lymphatic vessels. The aim of this study was to relate the incidence of lymphocele with immunosuppression among 158 renal transplant patients operated with routine closure of all the visible lymphatic vessels around the iliac vessels and at the renal hilum. The incidence of lymphocele was not significantly different among the various immunosuppressive regimens. 相似文献
