Randomized Controlled Trial Clinical Trial
Prednisone withdrawal 14 days after liver transplantation with mycophenolate: a prospective trial of cyclosporine and tacrolimus.
The long-term complications of immunosuppressive therapy such as diabetes, hypercholesterolemia, and hypertension are a major source of morbidity in liver transplant recipients. In this prospective, randomized, open-label study we completely withdrew prednisone (PRED) 14 days after liver transplantation in an effort to decrease these metabolic complications. Patients were maintained on mycophenolate mofetil (MMF) in combination with either cyclosporine (CsA; Neoral formulation) or tacrolimus (TAC). Thus, we also were able to compare CsA to TAC in patients not receiving PRED with respect to efficacy, toxicity, and effect on posttransplant metabolic complications. ⋯ MMF in combination with either TAC or CsA allows withdrawal of PRED 14 days after liver transplantation with a moderate rejection rate and no immunologic graft losses. Early PRED withdrawal decreases posttransplant diabetes, hypercholesterolemia, and hypertension, but patients maintained on TAC have lower serum cholesterol levels and a lower incidence of hypertension than CsA-treated patients.

The risk associated with transplantation of renal allografts from hepatitis B virus core antibody-positive (HBcAb(+)), hepatitis B virus surface antigen-negative (HBsAg(-)) donors is not well defined. ⋯ Transplantation of renal allografts from HBcAb(+), HBsAg(-) donors was not associated with clinically detectable HBV disease or antigenemia. However, recipients had a significantly increased risk of HBV seroconversion, consistent with exposure to HBV antigen. These results suggest that HBcAb(+) kidneys can be safely used if transplanted into appropriate recipients, but highlight the need for effective HBV vaccination and vaccine-response monitoring in potential recipients.
