Efficacy of short-term intravenous clindamycin prior to oral clindamycin-rifampicin treatment in hidradenitis suppurativa: a retrospective case series.

antibiotics represent the first-line hidradenitis suppurativa (HS) treatment, although HS is not an infectious disease1 . Prolonged antibiotic courses exhibit an anti-inflammatory effect, utilized for treating follicular/inflammatory skin diseases, e.g. acne and rosacea. Clindamycin/rifampicin or tetracyclines are usually administered for 10 to 12 weeks in moderate-to-severe HS treatment1 , mostly based on retrospective studies using non-validated severity scoring systems.
