Are chronic hepatitis C viral infections more benign in patients with hemophilia?
GROUND AND AIMS: Cirrhosis is associated with thromboses of the intrahepatic vasculature. This raises the possibility that HCV infections in hemophiliacs may differ from those in non-hemophiliacs METHODS: Liver biopsy findings from 12 hemophiliacs and 20 age- and gender-matched, non-hemophiliac controls with chronic hepatitis C viral (HCV) infections were compared for inflammatory activity and fibrosis. RESULTS: The mean ages of hemophiliacs and controls were 35.0 +/- 3.0 yr and 39.6 +/- 5.6 yr, respectively (P= 0.2). Serum aspartate aminotransferase (AST) levels were lower (44 +/- 13 vs 70 +/- 43 U/L) and the duration of the partial thromboplastin (PTT) time longer (49.2 +/- 16.9 vs 31.2 +/- 1.2 s.) in hemophiliacs than in controls (P < 0.02 and <0.001, respectively). Six of the seven hemophiliac patients (86%) and 8/17 controls (46%) were infected with genotypes 1a or 1b with the remainder being infected with 2b, 3a, or 3b. Histological activity and fibrosis scores were significantly
