Minocycline-induced Autoimmune Syndromes: Report of a Case and
Review of the Literature
Minocycline is commonly used in the treatment of acne vulgaris and rosacea. In recent years, its efficacyin rheumatoid arthritis (RA) was established. Cases of minocycline-induced autoimmune syndromes havebeen reported. We described the first report of a Chinese patient who developed minocycline-inducedvasculitis and performed a literature review on this topic. Physicians should be aware of this adverse effectof minocycline.

As minocycline had been stopped for 4 monthsand there were persistent symptoms, prednisolone wascommenced at a dose of 0.5 mg/kg/day.
She responded partially to steroid treatment with animprovement in ankle movement. Steroid dose was graduallytailed down.

Minocycline-induced autoimmune syndromes can becategorized into 4 types, namely minocycline-induced serumsickness, minocycline-induced lupus, minocycline-induced
