Primary liver transplantation for autoimmune hepatitis: A comparative analysis of the European Liver Transplant Registry

The principal aim of this study was to compare the probability of and potential risk factors for death and graft loss after primary adult and pediatric liver transplantation in patients undergoing transplantation for autoimmune hepatitis (AIH) to those in patients undergoing transplantation for primary biliary cirrhosis (PBC; used as the reference group) or alcoholic cirrhosis (used as an example of a nonautoimmune liver disease). The 5‐year survival of patients undergoing transplantation for AIH (n = 827) was 0.73 [95% confidence interval (CI) = 0.67‐0.77]. This was similar to that of patients undergoing transplantation for alcoholic cirrhosis (0.74, 95% CI = 0.72‐0.76, n = 6424) but significantly worse than that of patients undergoing transplantation for PBC (0.83, 95% CI = 0.80‐0.85, n = 1588). Fatal infectious complications occurred at an increased rate in patients with AIH (hazard ratio = 1.8, P = 0.002 with PBC as the reference). The outcome of pediatric AIH patients was similar to that of adult patients undergoing transplantation up to the age of 50 years. However, the survival of AIH patients undergoing transplantation beyond the age of 50 years (0.61 at 5 years, 95% CI = 0.51‐0.70) was significantly reduced in comparison with the survival of young adult AIH patients (0.78 at 18‐34 years, 95% CI = 0.70‐0.86) and in comparison with the survival of patients of the same age group with PBC or alcoholic cirrhosis. In conclusion, age significantly affects patient survival after liver transplantation for AIH. The increased risk of dying of infectious complications in the early postoperative period, especially above the age of 50 years, should be acknowledged in the management of AIH patients with advanced‐stage liver disease who are listed for liver transplantation. It should be noted that not all risk factors relevant to patient and graft survival could be analyzed with the European Liver Transplant Registry database. Liver Transpl , 2010.

Tacrolimus-based, steroid-free regimens in renal transplantation: 3-year follow-up of the ATLAS trial.

Background Long-term use of corticosteroids is associated with considerable morbidity, including cardiovascular and metabolic adverse effects. Methods This study evaluated the long-term efficacy and safety of two steroid-free regimens compared with a triple immunosuppressive therapy in renal transplant recipients. This was a 3-year follow-up to a 6-month, open-label, randomized, multicenter study. Results Data from 3 years were available for 421 (93.3%) of 451 patients in the original intent-to-treat population (143 tacrolimus/basiliximab [Tac/Bas], 139 tacrolimus/mycophenolate mofetil [Tac/MMF], and 139 tacrolimus/MMF/steroids [triple therapy]). In the time interval from 6 months to 3 years after transplantation, the incidence of biopsy-proven acute rejection was low and similar (Tac/Bas, 2.1%; Tac/MMF, 2.2%; triple therapy, 2.2%); Most rejection episodes occurred during the first 6 months of the study. Graft survival was high (Kaplan-Meier estimates: 92.7%, 92.5%, and 92.5%), as was patient survival (93.1%, 96.4%, and 97.0%). There were 10 graft losses (n=2, 4, and 4) and 12 patient deaths (n=5, 2, and 5). Renal function was well preserved throughout the study and similar between groups. There was a trend toward improved cardiovascular risk factors in the Tac/Bas group, including reduced total and low-density lipoprotein cholesterol and lower new-onset insulin use. There were no between-group differences in the incidence or type of adverse events. Conclusion Higher rates of acute rejection early in treatment were seen with the steroid-free regimens, but this did not translate into poorer long-term outcomes, such as graft and patient survival and renal function. A trend for a more favorable cardiovascular risk profile was observed for steroid-free immunosuppression with Tac/Bas.
