title: [Prevention and treatment of hepatitis C in patients on dialysis].
abstract: Nosocomial transmission of blood-borne pathogens, including hepatitis C virus infection, is the most common one in a dialysis center setting. The prevalence of HCV antibodies is by far higher in patients undergoing maintenance hemodialysis therapy than in those on peritoneal dialysis. Standard infection prevention measures in hospital settings and measures of infection prevention in dialysis units should be performed. They include serologic testing for HCV of every new patient in a dialysis unit as well as routine testing of all patients every six months. Hepatitis C therapy is recommended in patients on dialysis who have detectable HCV RNA, positive liver biopsy (portal or bridging fibrosis or moderate stage of necroinflammation), younger patients (less than 65 years), and transplantation candidates. When evaluating ALT, it should be kept in mind that ESRD patients have ALT levels lower than general population, making ALT level not relevant parameter of liver disease activity in these patients. Results of hepatitis C therapy with interferon alpha and peginterferon alpha are similar to those in the general population but with more common side effects, which may require therapy discontinuation. Due to the possibility of anemia, ribavirin is contraindicated in patients with ESRD. Around 30% of patients treated with peginterferon have sustained viral response, 25%-45% of them have end of treatment viral response, and 50%-80% have end of treatment biochemical response (ALT normalization). Numerous clinical trials have established that the decrease in HCV load and prolonged suppression of viral replication during interferon therapy significantly reduce hepatic inflammation and consequently postpone progression of fibrosis to cirrhosis.
