Hepatitis B and Hepatitis C Virus Infection and Outcome of Hemodialysis and Kidney Transplant Patients

Abstract

AIM: A comparison of the outcome of hepatitis virus-positive and -negative kidney transplant and hemodialysis patients was the aim of this investigation. MATERIALS AND METHODS: The study involved 384 kidney transplant patients (67 HBsAg positive, 39 anti-HCV positive, 278 hepatitis negative), transplanted between 1987 and 2001, and 403 hemodialysis patients (128 HBsAg positive, 83 anti-HCV positive, 192 hepatitis negative) who had started hemodialysis and were referred to the kidney transplant waiting list during the same period. RESULTS: Hemodialysis patients were older than transplant patients. Comparison of the groups' survival rates, adjusted for patient age, showed that all kidney transplant patients survived longer than hemodialysis patients (p < 0.001). HBV infection had a negative impact on patient survival, especially in hemodialysis patients. HCV infection did not have a significant influence on patient survival. Cardiovascular disease was the main cause of death of all hemodialysis- and hepatitis-negative transplant patients. Liver failure was one of the leading causes of death in HBV-positive transplant patients. Mortality risk was higher for older patients, HBV-positive and -negative hemodialysis patients. CONCLUSIONS: Kidney transplantation offers longer survival for hepatitis-positive and -negative hemodialysis patients. HBV but not HCV infection had a negative impact on ESRD patient survival.
