Background/aims: The influence of end-stage kidney failure on the progression of liver disease in patients infected with hepatitis C virus and treated with hemodialysis is still controversial.
Methodology: Liver histology of 154 hepatitis C virus infected non-uremic patients was compared with liver histology of 13 hepatitis C virus infected uremic patients treated with hemodialysis.
Results: In either group of altogether 167 patients, no normal liver histology was found. Each patient had at least a low-grade lobular and/or portal inflammation. However, statistically significant differences were observed between hepatitis C virus infected uremic and non-uremic patients in the extent of intralobular changes, portal inflammation, and degree of fibrosis.
Conclusions: Non-uremic hepatitis C virus infected patients appear to have more active and progressive liver disease than hepatitis C virus infected patients on hemodialysis. Regular follow-up of uremic patients, associated with earlier detection of hepatitis C virus infection, so as suggested uremia-associated impaired immunoreactivity and increased levels of hepatocyte growth factor described recently, might be implicated in a more favorable course of hepatitis C virus infection in uremic patients. In addition, due to the absence of normal liver histology in either group of hepatitis C virus infected patients, we propose liver biopsy to be mandatory in all these patients, provided that no contraindications exist clinically.
