Does Cyclosporine Have a Beneficial Effect on the Course of Chronic Hepatitis C Infection After Renal Transplantation?

The aim of our study was to assess the long-term liver histology in renal transplant patients infected with hepatitis C virus (HCV) who were treated with a cyclosporine-based regimen. Among 55 anti-HCV(+)/RNA(+) patients, liver biopsies (LB) were requested every 3 to 4 years after transplantation: two LBs (n = 55); three LBs (n = 44); four LBs (n = 10). Overall, the rate of liver fibrosis progression was 0.07 ± 0.03 Metavir U/y. Only three patients out of 55 (5.4%) developed cirrhosis. Liver fibrosis remained stable throughout follow-up in 21 patients; increased in 21 patients; and improved in the remaining 13 patients. The incidence of posttransplant diabetes mellitus was low (9%). We concluded that HCV infection is not harmful to liver histology in more than 50% of renal transplant patients with grafts functioning more than 6 years. Cyclosporine might have beneficial effects on the natural course of HCV infection after renal transplantation.
