Preventing relapse of major depression during interferon-alpha therapy for hepatitis C--A pilot study.

Depression is common in hepatitis C, exacerbated by interferon, and is a major reason for discontinuing interferon therapy. We aimed to determine (1) whether patients with a history of major depression could complete a course of peginterferon alpha-2a and ribavirin if pretreated with escitalopram and (2) the relapse rate of depression during the course of therapy in these subjects. Ten patients were enrolled in the study and treated with escitalopram. The Hamilton Depression Rating Scale (Ham-D) and other psychiatric scales were administered throughout the study. There were no statistically significant increases in mean Ham-D scores. No subjects were discontinued from the study due to depression relapse. Nine of 10 subjects maintained remission of depression throughout the study. We conclude that pretreatment with escitalopram in subjects with major depressive disorder in remission may prevent recurrence of major depression during a course of interferon and ribavirin therapy for hepatitis C.
