Assessment of chronic hepatitis C virus infection requires a liver biopsy in most circumstances. There is a reluctance to perform liver biopsy in haemophiliacs because of a perceived risk of haemorrhage, although with adequate factor concentrate replacement in patients without factor concentrate inhibitors it should be safe. We report a 4‐year experience of liver biopsy in patients with haemophilia infected with chronic hepatitis C virus. Of 55 patients seropositive for anti‐HCV, 35 have undergone liver biopsy; the median age of this group was 33 years (range 13–68). Seven patients had a normal liver. 22 had portal tract inflammation, four with lymphoid aggregates. Mild piecemeal necrosis was observed in only two and no bile duct injury was found. 11 patients had mild mixed micro‐ and macro‐vesicular fat. 19 patients had no evidence of fibrosis despite an estimated median duration of disease of 20 years (range 8–43). In the remaining 16 patients the maximum degree of fibrosis achieved was stage III. Patients with more significant fibrosis could not be identified on the basis of ALT or HCV RNA. There were no complications of liver biopsy in this series. Liver biopsy following a well‐defined protocol in chronic hepatitis C virus haemophiliac carriers is safe in the absence of factor concentrate inhibitors. In this young group of patients without HIV infection there was no evidence of significant liver disease despite a considerable duration of disease. Performing liver biopsy allows accurate information to be given to the patient and avoids unnecessary therapy. The relative youth of this group may be important in the light of the benign histology.
