Randomized Controlled Trial
Tacrolimus monotherapy without steroids after liver transplantation--a prospective randomized double-blinded placebo-controlled trial.
Early steroid withdrawal after liver transplantation (LT) is desirable in order to reduce steroid side effects. Between February 2000 and August 2004, 110 patients after LT were included in this prospective, randomized, double-blind, placebo-controlled trial. Randomization was performed before LT. ⋯ Two patients in the placebo group but none in the steroid group experienced chronic rejection (p = 0.257). The rates of side effects were (placebo versus steroid, respectively): CMV infection 25% versus 33% (p = 0.336), post-transplant diabetes 30% versus 53% (p = 0.024), hypertension 39% versus 52% (p = 0.248), hypercholesterolemia 10% versus 41% (p = 0.002) and hypertriglyceridemia 32% versus 54% (p = 0.046). In conclusion, early steroid withdrawal after LT is feasible under tacrolimus monotherapy without increased rejection rates and with a lower rate of side effects.

Randomized Controlled Trial
Cyclosporine sparing with mycophenolate mofetil, daclizumab and corticosteroids in renal allograft recipients: the CAESAR Study.
Although the calcineurin inhibitors (CNI) cyclosporine (CsA) and tacrolimus are highly effective immunosuppressants, they are associated with serious side effects. There is great interest in immunosuppressive regimens that permit reduction or elimination of CNIs, while maintaining adequate immunosuppression and acceptable acute rejection rates. ⋯ At 12 months, the incidence of biopsy-proven acute rejection was significantly higher in the CsA withdrawal group (38%) vs. the low- or standard-dose CsA groups (25.4% and 27.5%, respectively; p < 0.05). In summary, a regimen of continuous low-dose CsA with MMF, CS and daclizumab induction is a clinically safe and effective immunosuppressive regimen in renal transplant recipients.

Randomized Controlled Trial Multicenter Study Comparative Study
Everolimus versus azathioprine in maintenance lung transplant recipients: an international, randomized, double-blind clinical trial.
Everolimus is a proliferation signal inhibitor with immunosuppressive activity that may reduce the rate of progression of chronic rejection, bronchiolitis obliterans syndrome (BOS), after lung transplantation. In a randomized, double-blind clinical trial, 213 BOS-free maintenance patients received everolimus (3 mg/day) or azathioprine (AZA, 1-3 mg/kg/day) in combination with cyclosporine and corticosteroids. The prospectively defined primary endpoint was the incidence of efficacy failure (decline in FEV1 >15%[deltaFEV1 >15%], graft loss, death or loss to follow-up) at 12 months. ⋯ At 24 months, only incidence of acute rejection remained significantly less in the everolimus group. Treatment discontinuations (particularly due to adverse events), serious adverse events and high serum creatinine values were more common with everolimus. For the first time, a drug has demonstrated significant slowing of loss in lung function, suggesting that patients kept on prolonged maintenance treatment with everolimus may benefit from replacing AZA with everolimus 3 months after lung transplantation.

Randomized Controlled Trial Multicenter Study Clinical Trial
fluvastatin prevents cardiac death and myocardial infarction in renal transplant recipients: post-hoc subgroup analyses of the ALERT Study.
Renal transplant recipients have a greatly increased risk of premature cardiovascular disease. The ALERT study was a multicenter, randomized, double-blind, placebo-controlled trial of fluvastatin (40-80 mg/day) in 2102 renal transplant recipients followed for 5-6 years. The main study used a composite cardiac end-point including myocardial infarction, cardiac death and cardiac interventions. ⋯ Fluvastatin use was associated with reduction in cardiac death or nonfatal myocardial infarction, which achieved statistical significance in many subgroups. The subgroups included patients at lower cardiovascular risk, who were younger, nondiabetic, nonsmokers and without pre-existing CVD. These data support the early introduction of statins following renal transplantation.
