Carbamazepine is a widely used drug. It is commonly associated with hepatic abnormalities, ranging from an asymptomatic rise in liver function tests to acute liver failure. The most severe reaction occurs as part of a generalised hypersensitivity reaction, also known as drug reaction, eosinophilia and systemic symptoms (DRESS). We describe a case of a young adult who presented with non-specific symptoms, which progressed to fulminant hepatic failure, displaying the hallmarks of DRESS. We highlight the need for awareness of such an association.

Patients with hereditary bleeding disorders who received non-virally inactivated plasma-derived clotting factor concentrates before the mid-1980s invariably became infected with hepatitis C virus (HCV). Therapy with interferon alpha (IFN-alpha) alone has been disappointing in this group. We conducted an open-label study, using a combination of IFN-alpha2b (3 million units three times per week) and ribavirin 1-1.2 g/d in 28 patients with hereditary bleeding disorders. Twenty-one of the 28 patients had liver biopsy-confirmed chronic hepatitis (median histological activity index 5; range 1-10) and all patients were HCV RNA positive by PCR. Virological response rate to therapy at 3 months was 82% (23 out of 28). Three HIV co-infected patients showed an early virological response with loss of HCV RNA, but two subsequently relapsed after 3 and 6 months of therapy. Four patients stopped treatment early (one at 4, one at 7 and two at 9 months) because of treatment-related side effects, although three of these have maintained a virological response. Seventeen patients completed the 48-week course. Twenty of the 28 (71%) treated have had a durable virological response with a median follow-up of 16 months (range 1-24). Combination therapy represents a significant advance in the treatment of hepatitis C in patients with hereditary bleeding disorders.
