The prevalence of inverse recurrent suppuration: a population‐based study of possible hidradenitis suppurativa

摘要: Summary Background Hidradenitis suppurativa (HS) is a chronic inflammatory disease involving inverse recurrent suppuration (IRS). The epidemiology of the not well described, with previous studies reporting prevalence estimates from 0·00033% to 4%. Objective To determine IRS in large population-based survey. Methods Data were obtained general cross-sectional population study Denmark. A validated self-administered questionnaire was used identify IRS. Persons combination outbreaks ‘boils’ during last 6 months predefined areas and minimum two boils identified. Results A total 16 404 adults aged 30–89 years provided data overall found be 2·10% [95% confidence interval (CI) 1·88–2·32]; men it 1·58% (95% CI 1·29–1·86) women 2·56% 2·21–2·86). No for 20–29 years included. declined age. majority cases (72·9%) had body mass index ≥ 25 kg m−2 77·7% current or ex-smokers. mean number inflamed lesions 6·5 (range 2–67) 6 months. affected mostly genitalia (43·4%) groin (39·8%) ‘other places’ (not specified) (78·8%) men. Conclusions Data on suggest that HS may more prevalent than previously suggested, comparable other major dermatoses, e.g. psoriasis. However, as no physician examination done, risk recall information bias limitation.
