[Systemic treatment of moderate/severe hidradenitis suppurativa]. / Systemische Therapie der mittelschweren/schweren Hidradenitis suppurativa.

Systemic treatment together with radical surgical excision is the most important treatment option for all severity grades of hidradenitis suppurativa. Tetracycline in mild-to-moderate forms and clindamycin in combination with rifampicin in moderate-to-severe forms are guideline-compliant first-line therapy with a good clinical response. Other antibiotics such as ertepenem or multiple combinations are recommended as last-line therapy due to a lack of data. Success rate with dapsone and retinoids, on the other hand, are insufficient-only acitretin can be recommended on the basis of the available studies, but with limited success. With the TNF-alpha blocker adalimumab, an effective and safe long-term therapy is available-further biologics are in clinical trials and could significantly expand the treatment portfolio in the future.
