Impact of steroid-avoidance immunosuppression on long-term outcome after liver transplantation for HCV cirrhosis: the need for well documented long-term follow-up

Abstract

Aim: study impact of steroid avoidance on HCV recurrence after transplantation.

Methods and material: 35 HCV pats, being part of prospective, randomized, double-blind, placebo-controlled study comparing Tacrolimus (TAC)-Placebo (PLAC) (n = 14) to TAC-short-term (2 mo) low-dose steroid (STER) (n = 21), had 5 years follow-up. Primary endpoint was 1 and 5 years survival; secondary (composite) endpoint comprised HCV related cirrhosis, re-transplantation (re-LT) and death.

Results: 1 and 5-years survival were 93% and 75% in TAC-PLAC group; 91% and 66% in TAC-STER group (p 0.38). Two (14.3%) TAC-PLAC pats died due to HCV cirrhosis at 54 and 72 mo; 7 (33%) TAC-STER pats died due to cholestatic hepatitis at 5.8 and 9 mo, to cirrhosis at 18, 22, 34, 73 and 79 mo (p 0.20). Composite endpoint at 5 years didn't show advantage in favor of TAC-PLAC patients (5/14 [35.7%] vs. 9/21 [42.8%] pts, p.0.69). Early biopsies seemed more favorable in TAC-PLAC pats; at 5 years results were identical for both groups. Only 1 (7.1%) TAC-PLAC and 2 (9.5%) TAC-STER pats needed rejection treatment.

Conclusion: immunosuppression using steroid avoidance or short-term use had similar outcomes. Well documented long-term follow-up, including biopsies, is necessary in order to make conclusions in relation to impact of steroid use on outcome of HCV liver recipients.
