The Successful Use of Upadacitinib as Monotherapy for Hidradenitis Suppurativa and Ulcerative Colitis in the Setting of Refractory Disease

Hidradenitis suppurativa (HS) and ulcerative colitis (UC) are associated chronic inflammatory conditions with complex disease courses and potential for overlapping therapeutic management. We describe a case of severe pediatric HS and UC that were poorly controlled despite several standard‐of‐care therapies, including infliximab and ustekinumab. Transitioning the patient to upadacitinib monotherapy resulted in clinical improvement of both her UC and HS within 3 months, and she was then able to be weaned off her other systemic therapies. While upadacitinib is not currently FDA‐approved for HS or pediatric UC, this case report shows promise for upadacitinib monotherapy for both of these complex inflammatory disorders.
