RESUMEN
Hidradenitis suppurativa (HS) is a chronic, inflammatory condition associated with numerous comorbidities, but there has been no broad-spectrum investigation into the dermatological comorbidities that are associated with HS using nationally representative data. We therefore analysed the 2016-2018 National Inpatient Sample for adult patients with and without HS and used multivariable logistic regression to determine correlations between HS and 25 dermatological conditions, adjusting for age, ethnicity and race, sex and insurance type. As seen previously, HS is more likely to affect women and Black people. The prevalence of having any of the 25 dermatological conditions was higher in patients with HS than without (24.60% vs. 5.30%, P < 0.001) and HS was specifically associated with 18 of the 25 dermatological conditions. This research confirms anecdotal disease relationships and identifies novel correlations between HS and dermatological conditions using a national patient population.
