Thirty patients who had not previously received treatment with factor VIII concentrate or who had been treated only infrequently with factor VIII concentrate were studied after a transfusion of factor VIII. Tests of liver function were performed frequently. Four patients had evidence of chronic liver disease before transfusion. In 17 of the remaining 26 patients serum transaminase activities became raised and 10 patients developed jaundice. All of the nine patients who had not previously received factor VIII transfusion developed non-A non-B hepatitis. Four out of 10 patients followed up for a year had persisting abnormalities of liver function.The pattern of illness suggests that more than one serotype of non-A non-B hepatitis virus may be transmitted by factor VIII concentrate prepared by the National Health Service from volunteer donors in the United Kingdom.

Ovarian hyperstimulation syndrome (OHSS) is a potentially fatal condition associated with the therapeutic induction of ovulation in infertility. Liver function abnormality has been previously reported in four patients, one of whom had ultrastructural abnormalities on liver biopsy. This paper describes a patient presenting with severe OHSS 16 days after ovulation had been induced. Liver function abnormality was apparent 11 days later, with a sustained rise in alkaline phosphatase and aspartate aminotransferase (AST) which lasted up to 2 months. A liver biopsy performed during the second month of her protracted hospital admission showed marked zonal fatty change (acinar zone 1) and associated inflammation, with mitochondrial crystalline inclusions and rough endoplasmic reticulum dilatation on electron microscopy. This report discusses the clinical features and possible aetiological factors.
