Impact of hepatitis on renal transplantation.
In order to delineate the incidence, etiology, and impact of liver disease in renal transplant patients, we reviewed 405 consecutive transplants performed between 1970 and 1980. Hepatic dysfunction of at least 2 weeks' duration was diagnosed in 42 patients (10.4%). Of 28 patients acquiring hepatitis in the first post-transplant year, 26 (92.8%) developed chronic hepatitis; of 14 acquiring hepatitis after the first year, 9 (64.2%) developed chronic hepatitis. Of the 42 patients, 19 (45.2%) died, as compared with 16% of the nonhepatitis patients (P less than 0.001). Only one of these patients died of liver failure, with 15 of the 19 (78.9%) dying of extrahepatic infection. In addition, 12 of the 23 survivors (52.1%) suffered life-threatening infections from which they recovered, as compared with 20% of the nonhepatitis patients (P less than 0.01). Conversely, graft survival was significantly increased among the hepatitis patients (73% 1-year cadaveric allograft survival as compared with 50% for the nonhepatitis patients (P less than 0.01)). The etiology of the liver disease was identified in the minority of patients: 5 (11.9%) with hepatitis B, with none occurring since 1973; 10 (23.8%) with evidence of cytomegalovirus infection; and 1 (2.3%) with azathioprine toxicity. We conclude that the major cause of liver disease in renal transplant patients is non-A, non-B hepatitis, and furthermore, that this disease has a marked immunosuppressing effect resulting in increased allograft survival and a marked increase of life-threatening extrahepatic infection.
