Combined Biologic and Surgical Interventions for Hidradenitis Suppurativa: A Systematic Review

Abstract

Introduction. Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent painful or suppurative lesions due to follicular occlusion. Biologics and other treatment modalities such as surgical excision are commonly used in the treatment of severe HS. However, despite the frequent use of biologics and surgical interventions in the treatment of patients with HS, an assessment of their combined effects is lacking. This systematic review aims to qualitatively analyze the efficacy of combined biologic and surgical treatment for HS. Methods. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines were followed. The databases PubMed (MEDLINE), Embase, Cochrane (CENTRAL), ClinicalTrials.gov, MedRxiv.org, and the International Clinical Trial Registry were searched from inception until May 1, 2023. Results. A total of 1,145 studies were screened, with eight studies included for data extraction. Patients receiving combined biologic and surgical treatment showed greater improvement in the severity measurements of HS, including HS Impact Assessment, HS Physician Global Assessment, HS Sartorius Score, International Hidradenitis Suppurative Severity Score, HS recurrence rate, and Dermatology Life Quality Index. However, three studies reported a prolongation of wound healing with combined biologic and surgical treatment. Conclusion. Our systematic review highlights the additive effects of using biologics and surgery together to treat HS compared to either treatment alone. However, when both treatment modalities are used simultaneously, the potential risk of prolonged wound healing must be considered. Due to the limited number and heterogeneity of the included studies, more clinical trials are needed to establish diagnostic conclusions.
