Examining the race-specific prevalence of hidradenitis suppurativa at a large academic center; results from a retrospective chart review

Dermatol Online J. 2017 Jun 15;23(6):13030/qt9xc0n0z1.


Hidradenitis suppurativa (HS) is a chronic, inflammatory, debilitating disease of unknown etiology. HS can occur in people of all ethnicities and ages, and affects approximately 3-4% of the United States. To date, few studies have specifically examined the race prevalence of HS; further epidemiological research is needed to identify specific trends among HS and its racial predilections. At our center, 1.3% of African-American patients were seen for HS, compared to 18% of Caucasian patients (p<0.05), and the percent ratio of African-American versus Caucasian patients with HS was 7.22:1. Our number ratio of African-American patients versus Caucasian patients with HS was 1.19:1. Studies performed at Henry Ford Medical Center and University of Pittsburgh report ratios of 1.64:1 and 1.98:1 respectively. These data support study trends suggesting HS is more common among patients of African-American descent. A large, population-based study across the United States is needed to better assess the associations between ethnicity and HS. Examining this patient population has the potential to improve our understanding of HS pathophysiology, and will enable clinicians to better manage patients with this disease.
