Effect of alcohol use on allograft rejection rates after liver transplantation for alcoholic liver disease.

Alcoholic liver disease is a major cause of liver disease and has become an ever-increasing indication for liver transplantation (LTx). Follow-up studies have reported a higher rate of alcohol recidivism in patients transplanted for alcoholic hepatitis, compared with those transplanted for endstage alcohol-associated cirrhosis. It is assumed widely that recurrent alcohol use is associated with reduced compliance with immune suppression and, as a result, an increased risk of graft rejection and loss. To assess this question, 209 alcoholic patients transplanted for either alcoholic hepatitis with cirrhosis or cirrhosis alone between January 1, 1986 and December 31, 1991 were followed, with a mean follow-up of 4.4 +/- 0.6 years. There were 175 episodes of acute cellular rejection (ACR) that occurred in 137 patients, for an overall rejection rate of 83.7% or at a rate of 1.25 episodes/patient with rejection. The rate of ACR was three times as great in those who remained alcohol-abstinent (2.24 episodes/patient), compared with those who admitted to continued alcohol use (0.75 episodes/patient) (p < 0.01). A total of 33 episodes of chronic rejection occurred in 26 patients, for an overall rate of 12.4%. As was the case for ACR, the chronic rejection rate was greater among those who were continuously alcohol-abstinent, compared with those who intermittently used alcohol after successful LTx. There were no differences in the mean FK 506 or cyclosporin A levels in the groups with and without a rejection episode at the time the rejection episode was documented by liver biopsy.(ABSTRACT TRUNCATED AT 250 WORDS)
