Drug-induced hepatitis with autoimmune features during minocycline therapy

A 25-year-old woman with no history of liver disease developed liver dysfunction associated with severe Jaundice and general malaise following a prolonged therapy with minocycline for acne vulgaris. Serum anti-nuclear antibody was detected and immunoglobulin G level was elevated. Symptoms resolved and liver function normalized following minocycline discontinuation and corticosteroid administration. Our diagnosis was drug-induced hepatitis with autoimmune features, as liver histology revealed acute hepatitis. Drug-induced hepatitis should be considered when liver dysfunction or systemic symptoms develops during long-term minocycline therapy.
