Abstract

Aims: Chronic liver disease develops in the majority of non-uremic patients with hepatitis C virus (HCV) infection. The aim of this study was to analyze the evolution towards chronic hepatopathy in 19 cases of acute hepatitis C observed in hemodialysis patients from 1990 to 2001. Methods: A prospective follow-up study on HCV infection was conducted in 3 HD units from April 1990 to June 2001 to study clinical outcomes after acute hepatitis C. A total of 781 patients were tested monthly for alanine aminotransferase and anti-HCV in serum. In this period, 19 patients suffered from acute hepatitis C. Evolution to chronic liver disease in the follow-up was evaluated by means of biochemical (increased ALT) and virological criteria (HCV-RNA+). The transmission mechanism, the apparition of anti-HCV, clinical manifestations and mortality were also investigated. Results: In 15 (78.9%) of the 19 patients, the viremia remained positive (chronic viremia) and 11 patients (57.8%) evolved to chronic liver disease (chronic viremia and high transaminase levels) with a median follow-up of 3 years (range 1 – 6). Five of them who underwent liver biopsies had histologic signs of chronic active hepatitis. One of them (5.2%) evolved to liver cirrhosis in the follow-up. In 4 out of 19 patients (21%) the HCV infection resolved. Although 7 (36.8%) of them died in the follow-up, acute hepatitis C infection was not a short-term independent risk factor of death. Conclusions: Three years after acute hepatitis C, 87.5% of the hemodialysis patients remained HCV-RNA positive and 56.2% evolved to chronic liver disease. It is important to stress that HCV infection spontaneously cleared in 4 out of 19 patients (21%).
