|Abstract:||Background Hepatitis B may show a more aggressive course after kidney transplantation, but the factors associated with the progression of fibrosis in this group have not been identified.Objectives To determine the influence of hepatitis B virus (HBV) viral load and host-related factors on the progression of hepatic fibrosis in hepatitis B virus-infected renal transplant recipients.Patients and methods Renal transplant patients positive for HBV surface antigen (HBsAg) and submitted to a liver biopsy because of evidence of viral replication were included. Patients with advanced fibrosis (METAVIR F3-F4) were compared with patients with mild fibrosis (F0-F2) regarding sex, age, estimated time since infection, post-transplant time, donor type, history of renal transplantation, alanine aminotransferase, anti-hepatitis C virus, HBeAg and quantitative hepatitis B virus-DNA. Logistic regression analysis was applied to identify variables independently associated with more advanced fibrosis.Results Fifty-five patients (75% men, 41 +/- 11 years) with a mean post-transplant time of 5 +/- 4 years were included. HBeAg was detected in 67% of the patients and anti-hepatitis C virus in 35%. The median hepatitis B virus-DNA level was 2.8 x 10(8) copies/ml. Seventeen (31%) patients had advanced fibrosis. Using logistic regression analysis, the only variable that showed an independent association with more advanced stages of fibrosis was post-transplant time (P=0.03, odds ratio: 1.2, 95% confidence interval: 1.02-1.45).Conclusion Hepatitis B virus viral load, although very high, and hepatitis B virus/hepatitis C virus coinfection are not related to the intensity of liver fibrosis in renal transplant patients infected with hepatitis B virus. Post-transplant time was the only factor independently associated with more advanced liver fibrosis, suggesting the influence of immunosuppression on the progression of liver disease in these patients.|
