Prevalence of Acne Vulgaris Among Patients with HS

J Am Acad Dermatol; ePub 2018 Oct 1; Wertenteil, et al

Patients with hidradenitis suppurativa (HS) may benefit from assessment of acne status and optimization of co-management strategies, a recent study found. Researchers conducted a cross-sectional analysis identifying adults with acne vulgaris (AV) among HS and non-HS patients using electronic health records data from a population-based sample of >55 million patients. They found:

  • Prevalence of AV among adults with HS was 15.2% (7,315 /48,050), compared to 2.9% (497,360 /16,899,470) for adults without HS.
  • Prevalence was greatest among HS patients who were female (5,870/35,790; 16.4%), aged 18-44 years (5,260/28,870; 18.2%), non-white (3,120/17,825; 17.5%), obese (5,430/35,135; 15.5%), and had polycystic ovary syndrome (PCOS) (685/2,385; 28.7%).
  • HS patients had 4.51 times the odds of having AV compared to non-HS patients, and the higher likelihood of having AV persisted across all HS subgroups.
  • The association between HS and AV was generally stronger for patients who were male, aged ≥65 years, non-whites, and obese.
