Characterization of comorbidity heterogeneity among 13,667 patients with hidradenitis suppurativa. JCI insight Hua, V. J., Kilgour, J. M., Cho, H. G., Li, S., Sarin, K. Y. 2021


Hidradenitis suppurativa (HS) is a chronic, inflammatory skin disorder characterized by recurrent abscesses in the groin and flexural areas. HS is associated with a wide range of comorbidities that complicate the disease course. Although these comorbidities have been well-described, it remains unclear how these comorbidities co-associate and whether comorbidity profiles affect disease trajectory. In addition, it is unknown how comorbidity associations are modulated by race and gender. In this comprehensive analysis of 77 million patients in a large U.S. population-based cohort, we examine co-association patterns among HS comorbidities and identify clinically relevant phenotypic subtypes within HS. We demonstrate that these subtypes not only differ among races, but also influence clinical outcomes as measured by HS-related emergency department (ED) visits and cellulitis. Taken together, our findings provide key insights that elucidate the unique disease trajectories experienced by HS patients, and equip clinicians with a novel framework for risk stratification and improved targeted care in HS.
