Abstract
The spectrum of liver disease in a population of 293 patients receiving 353 renal transplants (1971-1984) was reviewed. This study looked retrospectively at the histological features of liver disease in this population, and prospectively at the clinical and biochemical features of liver disease associated with renal transplantation. In all patients, infection with hepatitis B was excluded. Six deaths, primarily attributable to hepatic failure have occurred: one, acute herpes simplex infection; one, subacute massive hepatic necrosis of uncertain etiology; two, pretransplant liver disease; and two, posttransplantation cirrhosis of uncertain etiology. Review of the hepatic histology of 26 patients with known liver disease following transplantation revealed a wide range of pathologies with few specific correlations with their clinical status or biochemical tests of liver function. The prevalence of hepatic dysfunction following transplantation in our patient population was assessed by prospective biochemical screening of 111 transplant recipients over a 6-month interval. During this time period, 27 patients (24%) displayed biochemical evidence of hepatic dysfunction. Liver disease was known to have predated transplantation in only three of 27. Episodes of abnormal liver function occasionally occurred during an identifiable acute illness (six of 27), although the majority (21 of 27) had chronic hepatic dysfunction. Transplant recipients with abnormal liver function could not be differentiated from a cohort with normal liver function on the basis of age, sex, duration of graft function, or alcohol/drug intake. The possible etiologies of nonhepatitis B liver dysfunction following renal transplantation are discussed, and the high prevalence of biochemical evidence of hepatic dysfunction in this population free of hepatitis B infection is emphasized.
