    Abstract:
    GOALS: To describe dermatologic side effects encountered during treatment of patients with chronic hepatitis C, and analyze factors predisposing to such reactions. BACKGROUND: Treatment of hepatitis C virus (HCV) infection with interferon (IFN) and ribavirin is associated with a number of mucocutaneous adverse reactions that have not been adequately studied. STUDY: A retrospective cohort study design was used to longitudinally describe mucocutaneous drug eruptions during IFN and ribavirin therapy in HCV-infected patients. Factors predictive of mucocutaneous eruptions were analyzed by the use of Kaplan-Meier curves and Cox proportional hazard model. RESULTS: A total of 286 HCV-infected consecutive patients were treated with one of the IFNα formulations plus ribavirin. The mean age was 51.1 years (SD 5.6). There were 6 female patients. There were 5 patients who were also infected with human immunodeficiency virus (HIV). Fifty-six percent of the patients were white, 37% were African American, and 14% were Hispanic. Twenty-one percent of all study patients developed mucocutaneous drug eruptions. The most common drug eruptions were eczematous drug eruptions (48%), seborrheic dermatitis (11%), and xerosis (8%). Dermatologic eruptions were a contributing factor in the decision to discontinue antiviral treatment in 10% of cases. Use of Pegylated IFN formulations (hazard ratio=1.86; 95% confidence interval, 1.04-3.34) and presence of HIV coinfection (hazard ratio=4.46; 95% confidence interval, 1.61-12.92) were associated with increased rate of skin reactions. CONCLUSIONS: Mucocutaneous reactions during IFN and ribavirin treatment of hepatitis C are common and are associated with HIV infection and use of Pegylated IFN.
