Withdrawal of cyclosporine or prednisone six months after kidney transplantation in patients on triple drug therapy: a randomized, prospective, multicenter study

Uncertainty exists regarding the necessity of continuing triple therapy consisting of mycophenolate mofetil (MMF), cyclosporine (CsA), and prednisone (Pred) after kidney transplantation (RTx). At 6 mo after RTx, 212 patients were randomized to stop CsA (n = 63), stop Pred (n = 76), or continue triple drug therapy (n = 73). The MMF dose was 1000 mg twice daily, target CsA trough levels were 150 ng/ml, and Pred dose was 0.10 mg/kg per d. Follow-up was until 24 mo after RTx. Biopsy-proven acute rejection occurred in 14 (22%) of 63 patients after CsA withdrawal compared with 3 (4%) of 76 in the Pred withdrawal group (P = 0.001) and 1 (1.4%) of 73 in the control group (P = 0.0001). Biopsy-proven chronic rejection was present in one patient in the control group, in nine patients after CsA withdrawal (P = 0.006 versus control group); and in four patients after discontinuation of Pred (NS). Graft loss occurred in two versus one patient after CsA or Pred withdrawal, respectively, and in two patients in the control group (NS). Patients who successfully withdrew CsA had a significantly lower serum creatinine during follow-up. Pred withdrawal resulted in a reduction in mean arterial pressure, and the total cholesterol/HDL ratio increased. In conclusion, rapid CsA withdrawal at 6 mo after RTx results in a significantly increased incidence of biopsy-proven acute and chronic rejection. Pred withdrawal was safe and resulted in a reduction in mean arterial pressure. However, patient and graft survival and renal function 2 yr after RTx were not different among groups

Oral ulcers in kidney transplant recipients treated with sirolimus and mycophenolate mofetil.

BACKGROUND: In an attempt to reduce calcineurin inhibitor toxicity, transplant patients treated with tacrolimus can be switched to maintenance treatment with sirolimus. METHODS: In a prospective, randomized, multicenter trial, 33 kidney transplant recipients on steroid-free maintenance treatment with tacrolimus and mycophenolate mofetil continued tacrolimus and mycophenolate mofetil (control group, n=18) or were converted from tacrolimus to sirolimus (study group, n=15) at 1 year after transplantation. RESULTS: The study was prematurely stopped as a result of a cluster of nine patients suffering from painful oral ulcerations in the study group. Oral ulcerations did not occur in the control group. The authors here report on the individual cases suffering from this side effect of the instituted immunosuppressive regimen. CONCLUSIONS: The authors review the literature with respect to the occurrence of oral ulcers associated with the use of sirolimus or mycophenolate mofetil and speculate on the causes of the high incidence of oral ulcers in their study group. Possible explanations are overimmunosuppression during the period of the conversion from tacrolimus to sirolimus without antiviral prophylaxis, the use of the oral emulsion instead of tablets, or the lack of corticosteroid co-administration

A controlled trial comparing two doses of cyclosporine in conjunction with mycophenolate mofetil and corticosteroids.

Contains fulltext : 185546.pdf (publisher's version ) (Closed access)It is unknown whether the addition of mycophenolate mofetil (MMF) to cyclosporine (CsA) and prednisone after renal transplantation (RTx) allows for a reduced dose of CsA, to minimize the incidence of CsA-related side effects and to reduce costs. Therefore, 313 renal allograft recipients were randomized for treatment with MMF (1000 mg twice a day), prednisone, and either conventional- or low-dose CsA during the first 3 mo after RTx. The target trough levels were 300 and 150 ng/ml, respectively, during the first 3 mo and 150 ng/ml in both groups thereafter. A total of 313 patients were included: 161 patients received a conventional dose and 152 received a low dose of CsA. During the first 6 mo after RTx, graft failure or patient death occurred in 19 of 161 patients (12%) in the conventional-dose group and in 11 of 152 patients (7%) in the low-dose group (not significant). Biopsy-proven acute rejection occurred in 36 of 161 patients (22%) in the conventional-dose group and in 29 of 152 patients (19%) in the low-dose group (not significant). The incidence of delayed graft function was similar in both groups (31 of 161 [19%] versus 28 of 152 [18%]; not significant). Serum creatinine did not differ between the conventional- and the low-dose groups: 151 +/- 56 micromol/L versus 142 +/- 49 micromol/L at 3 mo and 141 +/- 60 &mgr;mol/L versus 136 +/- 49 micromol/L at 6 mo. There were no differences between the groups regarding BP, lipid metabolism, and infectious complications. In the low-dose group, an estimated $500 per patient was saved on the costs of CsA. In conclusion, the addition of MMF to CsA and prednisone after RTx allows the use of a lower-than-conventional dose of CsA, without increasing the risk of rejection

No important influence of limited steroid exposure on bone mass during the first year after renal transplantation: a prospective, randomized, multicenter study.

Contains fulltext : 58803.pdf (publisher's version ) (Closed access)BACKGROUND: Steroid-related bone loss is a recognized complication after renal transplantation. In a prospective, randomized, multicenter study we compared the influence of a steroid-free immunosuppressive regimen with a regimen with limited steroid exposure on the changes in bone mass after renal transplantation. METHODS: A total of 364 recipients of a renal transplant were randomized to receive either daclizumab (1 mg/kg on days 0 and 10 after transplantation; steroid-free group n=186) or prednisone (0.3 mg/kg per day tapered to 0 mg at week 16 after transplantation; steroids group n=178). All patients received tacrolimus, mycophenolate mofetil, and, during the first 3 days, 100 mg prednisolone intravenously. Changes in bone mineral density (BMD) were evaluated in 135 and 126 patients in the steroid-free and steroids group, respectively. RESULTS: The mean (+/- SD) BMD of the lumbar spine decreased slightly in both groups during the first 3 months after transplantation (steroid-free -1.3 +/- 4.0% [P<0.01]; steroids -2.3 +/-4.2% [P<0.01]). In the following months, lumbar BMD recovered in both groups (P<0.01), resulting in a lumbar BMD at 12 months after transplantation comparable with the baseline value. No difference between the groups was found at 3 months (steroid-free versus steroids +1.0%; 95% confidence interval -0.0%-+2.0%, P=0.060) and at 12 months after transplantation (steroid-free versus steroids +0.9%; 95% confidence interval -0.8%-+2.6%, NS). CONCLUSION: The use of a moderate dose of steroids during 4 months after transplantation has no important influence on bone mass during the first year after renal transplantation. On average, both regimens prevented accelerated bone loss
