title: Effects of interferon treatment on the glucose metabolism of patients with chronic hepatitis C.
abstract: Background: The authors report on changes in carbohydrate metabolism observed in 32 patients undergoing therapy with interferon-alpha for chronic hepatitis C. Methods: Diabetes had been diagnosed in three patients and impaired glucose tolerance ascertained in one patient before interferon therapy was started. The remaining 28 patients were non-diabetic. Interferon-alpha was administered in 3-MU doses three times per week. Results: Glucose tolerance deteriorated in two of the three diabetics, and eventually these patients had to be switched from oral hypoglycemic agents to insulin. The patient with impaired glucose tolerance at baseline progressed gradually to overt diabetes. Nine of the 28 previously non-diabetic patients developed impaired glucose tolerance during interferon therapy. Conclusion: The deleterious effects of interferon-alpha on carbohydrate metabolism proved to be reversible. Regular monitoring of the glucose level of patients during and after interferon therapy is mandatory.
