title: Differential efficacy of corticosteroids and interferon in a patient with chronic hepatitis C-autoimmune hepatitis overlap syndrome.
abstract: The chronic hepatitis C-autoimmune hepatitis (AIH) overlap syndrome has been described in the literature, but to date appropriate therapy remains controversial. We report on a 28-year-old woman with hepatitis C-AIH overlap syndrome. The patient was infected with HCV genotype 1b and had laboratory and immunologic findings of AIH type 2 such as increased Igs and a high titer of antibodies against liver-kidney microsomes. Initial liver biopsy specimen demonstrated end-stage liver fibrosis due to chronic hepatitis. After long-lasting corticosteroid treatment, only partial remission was achieved. In contrast, short-term antiviral therapy with interferon-alpha2b in combination with ribavirin was followed by complete biochemical and virologic remission. However, 15 months later, a relapse of AIH was observed. After restarting corticosteroid treatment, transaminase levels completely normalized. Surprisingly, in this patient with overlap syndrome, short-term interferon therapy induced complete remission of chronic HCV infection and regression of severe liver fibrosis.
