Background. In 2001, we published early results of a prospective randomized trial of 71 patients who received either steroids or rabbit antithymocyte globulin (RATG) for orthotopic liver transplantation (OLT). We now report follow-up on these patients and additional patients undergoing steroid-free OLT. Methods. A total of 119 adult OLT recipients were prospectively randomized to receive either methylprednisolone 1,000 mg followed by a 3-month steroid taper or a steroid-free regimen of RATG 1.5 mg/kg during the anhepatic phase followed by a 1.5 mg/kg dose on posttransplant day 1. Maintenance immunosuppression consisted of tacrolimus and mycophenolate mofetil in both groups. Mycophenolate mofetil was weaned over 3 months in the first 71 patients and over 2 weeks in the last 48 patients, achieving tacrolimus monotherapy by 2 weeks posttransplant. Subsequently, a group of 24 sequential OLT recipients received the steroid-free (RATG) protocol. Endpoints of the study were survival, rejection, infectious complications, posttransplant diabetes, and recurrent hepatitis C virus. Results. One-year patient survival was 85% in each group of the prospective randomized trial with a mean follow-up of 18.5 months. One-year graft survival was 82% in the RATG group and 80% in the steroid group (P β«Ψβ¬ not significant). Patient and graft survival of the 24 nonrandomized RATG patients was 96% with a mean follow-up of 3 months. The incidence of rejection was not significantly different; however, 50% of the patients in the steroid group required pulse steroids to reverse the rejection compared with only one patient (1.6%) in the RATG group (P β«Ψβ¬ 03). The incidence of cytomegalovirus infection (P < .05) and posttransplant diabetes was higher in the steroid group (P β«Ψβ¬ .03). There was a trend toward decreased severity of hepatitis C virus in the RATG group. Conclusions. Steroid-free liver transplantation using RATG and early tacrolimus monotherapy effectively reduces immunosuppression-related complications with excellent survival.
