Efficacy of medical treatments for pediatric hidradenitis suppurativa: A systematic review

Abstract

Hidradenitis suppurativa (HS) is a chronic, inflammatory skin condition that has been insufficiently studied in the pediatric population. Timely and effective medical treatments may improve quality of life, mitigate disease burden, and prevent the need for invasive procedural interventions such as surgical excisions. However, there is a paucity of research on the efficacy of medical management strategies for HS in children and adolescents. The aim of this study was to perform a systematic review of the literature on the efficacy and safety of medical treatments for HS in patients <18 years of age. In April 2022, MEDLINE and EMBASE databases were searched for articles on the efficacy of medical treatments for HS in the pediatric population. Between 1984 and 2022, 35 articles (101 patients) met the inclusion criteria. Most patients had Hurley Stage II disease (46.7%, 35/75) followed by Stage I (36%, 27/75), and Stage III (17.3%, 13/75). 100% (23/23) of patients responded to antibiotics, 100% (8/8) to finasteride, 93.9% (31/33) to biologics, 80% (4/5) to oral retinoids, and 50% (6/12) to metformin. Overall, this study demonstrates that medical treatment regimens can improve HS symptoms in pediatric patients, but the extent of improvement is unclear, and the results were largely based on case reports or case series. Prospective studies are warranted to better understand the efficacy and safety of medical treatments for pediatric HS. Clinical trials of HS therapies need to be inclusive of pediatric patients to help define the optimal timing of treatment initiation and guide patient selection.
