Abstract

There are conflicting results in studies concerning the best marker for liver histopathological features of HCV infection in HD patients. We planned a prospective study to follow HCV viremia and laboratory parameters of HD patients and correlate these with clinic features and histopathological findings. We included 68 HCV infected patients (45 male, 23 female, age: 39.8 +/- 11.9 years, HD duration: 58.2 +/- 36.4 months) in our study. The follow-up period after the biopsy was 33.2 +/- 20.3 months. Patients liver enzyme (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT)) levels were determined monthly and ferritin levels every three months, and the mean value was recorded. We also screened patients for HCV RNA. During the follow-up period, 22 (32.4%) of the patients had positive RNA, 26 (38.2%) negative RNA. 20 (29.4%) had intermittent RNA positivity. The patients with high grade of portal necroinflammatory activity had significantly higher AST and ALT levels. In addition patients with high grade lobular activity had significantly shorter HD and HCV infection duration and higher AST, ALT and ferritin levels. AST levels were negatively correlated with duration of HD and HCV infection, and positively correlated with GGT and ferritin levels. Additionally, we found that ALT levels were negatively correlated with HD duration and positively correlated with GGT levels. ALT levels higher than 30 U/L were reflected necroinflammatory activity more significantly than levels higher than 40 U/L. Cirrhosis was detected in 5.9% of the patients, and we could not find any laboratory parameter that was correlated with stage of fibrosis. Although there is a high degree of liver involvement, cirrhosis is a relatively less frequent finding in HD patients. Serum aminotransferases and ferritin levels but not the pattern of HCV viremia are predictors of necroinflammatory activity in liver biopsy specimens. Liver biopsy obligatory to assess the disease activity in HD patients.
