Long-term minocycline use for acne in healthy adolescents can cause severe autoimmune hepatitis

Over the years, a variety of abnormal immune reactions to minocycline have been reported including arthritis, systemic lupus erythematosus, and hepatitis. The current report describes the detailed clinical and pathologic features of 3 patients who presented with chronic/autoimmune hepatitis alone while on minocycline at our hospital over a 2-year period. Minocycline use in these patients was temporally related to onset of severe hepatitis. Adolescents with such a reaction to minocycline have been included in previous reports but have not been well described as a distinct entity. We have compared our cases with similar cases previously reported with a review of the literature and a discussion of the implications for prescribing physicians.
