Is minocycline therapy in acne associated with antineutrophil cytoplasmic antibody positivity? A cross-sectional study.

Background: Minocycline (MN), one of the commonly prescribed therapies for acne, is known to be associated with autoimmune disorders including drug-induced lupus. However, data are sparse regarding the prevalence of autoimmune disease in acne or in patients with acne treated with MN.

Objectives: To establish the prevalence of antinuclear antibodies (ANA), antineutrophil cytoplasmic antibodies (ANCA) and new autoimmune syndromes in an MN-exposed and unexposed population with acne.
