Abstract
Depressive or psychotic symptoms are a well known side-effect of interferon alpha (INF-a). Therefore, the questions arises whether a chronic psychosis should be considered a contraindication for the treatment of active hepatitis C with INF-α. We report on a 38-year-old woman with a chronic schizophrenic psychosis, who acquired chronic aggressive hepatitis C. Considering the young age of the woman, the potential risk of developing a hepatocellular carcinoma and the result of the liver biopsy, treatment with interferon alpha 2 b (3 × 5 million IU/week) was started. The patient was seen three times a week, her psychiatric condition was monitored using the positive and negative symptoms score (PANSS). No signs of psychotic or depressive symptoms appeared during INF-α therapy. During the first 6 months the liver enzymes dropped slowly but the virus load was increasing. After adding ribavirin to the therapy, the liver enzymes dropped again, and the PCR carried out 9 months after initiation and 6 months after the end of the 12 months INF-α treatment did not detect any virus RNA. This positive result should encourage prospective studies including patients with these two diagnoses on whether patients benefit from INF-α.
