Clinical and Biological Characteristics of Hidradenitis Suppurativa

This study collects clinical and biological information about hidradenitis suppurativa (HS) — a painful, chronic skin condition that causes deep, recurring abscesses and scarring, primarily in areas like the armpits, groin, and buttocks. HS is often under-diagnosed and poorly understood, and treatments remain limited. This research aims to identify biological markers and patterns that could lead to better treatments. Both people with HS and healthy volunteers without skin conditions are invited to participate. Participants provide skin samples, blood samples, and detailed medical history information. You may be eligible if: - You are 13 years of age or older - You have a physician-confirmed diagnosis of HS (for the patient group), OR - You have no history of chronic skin conditions and no recent antibiotic use (for healthy volunteers) You may NOT be eligible if: - You are unable to give informed consent, and no parent or guardian is available to provide consent on your behalf Talk to your doctor to see if this trial is right for you.
