“…Calao et al could show that persons with HS were significantly more likely to be unemployed [2]. Theut Riis et al were able to show that persons with HS had received cash benefits or sick pay more often than persons without HS [22]. The same working group identified in their survey-based study an unemployment rate of 25.1% in the HS population versus 5.9% in the general population [23].…”

Prevalence and cutaneous comorbidities of hidradenitis suppurativa in the German working population

The association of hidradenitis suppurativa with other skin diseases has not yet been investigated in larger studies based on dermatological exams. The objectives of this study are to determine the prevalence and cutaneous comorbidities of hidradenitis suppurativa in the German working population. Between 2014 and 2017, 20,112 people in 343 German companies were examined for the presence of clinical features of hidradenitis suppurativa within the framework of a cross-sectional epidemiological study based on whole-body examinations. In addition, all cutaneous comorbidities were recorded. Point prevalence was calculated and the differences between individuals with and without hidradenitis suppurativa were determined by bivariate analysis. All statistical procedures were performed using SPSS 23.0 for Windows. Of 20,112 people examined, mean age was 43.6 ± 10.5 years; 52.3% were male. In total, n = 57 people (0.3%) with hidradenitis suppurativa were identified; 61.4% (n = 35) being male. In addition, non-inflammatory hidradenitis suppurativa-related lesions were found in 674 other individuals. In a bivariate comparison, patients with hidradenitis suppurativa showed significantly more frequently the following cutaneous comorbidities: acne vulgaris, psoriasis, seborrhoeic dermatitis, excoriations, and folliculitis. We determined a point prevalence of hidradenitis suppurativa of 0.3%. Since we have examined the working population, the healthy worker effect, which could have led to underestimation of prevalence, cannot be ruled out. The point prevalence of 0.3% for employed people in Germany and a prevalence of 3.0% for inflammatory and non-inflammatory hidradenitis suppurativarelated lesions show that hidradenitis suppurativa is an important disease for the whole health system.

“…When the studies were divided by diagnostic method, prevalence of self-reported HS was found to be 0.66% (95% CI 0.33 -1.09) while physiciandiagnosed HS was found to be 0.24% (95% CI 0.10 -0.44).

Background: Hidradenitis is a chronic relapsing follicular occlusive disease with a widely variable reported prevalence. The exact prevalence and incidence of HS is unknown. Objectives: To perform a systematic review and meta-analysis of the published literature to estimate the global incidence and prevalence of HS. Methods: Literature searches were performed on Medline, Embase, and Pubmed to identify studies reporting incidence and/or prevalence of HS. Pooled estimates of prevalence and incidence were calculated with a meta-analysis of proportions. Results: In total, 12 studies were included (Australia, Brazil, Denmark, France, Germany, Ireland, Israel, UK, USA) comprising a total population of 53,805,690. Eleven studies reported prevalence. The pooled proportion of individuals in the general population with HS was 0.36% (95% CI: 0.21, 0.56). Self-reported HS gave a higher prevalence estimate than clinician-diagnosed HS. HS is more prevalent in women. Average annual incidence of HS was 28.5 cases/100,000 (95% CI: 26.8, 30.1). Conclusions: We estimated the global prevalence of HS to be 0.36% with 3:2 female predominance and average annual incidence to be 28.5 cases/100,000

Prevalence of patients with self‐reported hidradenitis suppurativa in a cohort of Danish blood donors: a cross‐sectional study

Abstract: The prevalence of HS in the cohort of blood donors was estimated to 1·8% (95% CI 1·6-2·0%). Donors with HS reported characteristics similar to those reported for hospital-based patients with HS such as higher BMI, smoking rates and lower socioeconomic status than donors without HS.
