Hidradenitis suppurativa increases risk for Alopecia
In a study investigating the relationship between hidradenitis suppurativa and Alopecia areata in a U.S. sample, those with hidradenitis suppurativa had a significantly higher risk for Alopecia of any type and also lichen planopilaris.
“Both [Alopecia areata] and [hidradenitis suppurativa] likely involve an inciting event at the hair follicle, which leads to subsequent inflammation,” Joslyn S. Kirby, MD, MS, MEd, of the department of Dermatology at Penn State Milton S. Hershey Medical Center in Hershey, Pennsylvania, and colleagues, wrote.
The hidradenitis suppurativa (HS) group comprised patients aged at least 12 years with two separate HS-related claims in an 18-month period. The age- and sex-matched control group included randomly selecting individuals at a ratio of 10 controls to every one patient in the HS group. Controls were never diagnosed with HS, pilonidal cyst, acne conglobata or dissecting cellulitis of the scalp during the same period.
The researchers identified 36,450 matched controls and 3,645 patients with HS.
