Combination Therapies for Hidradenitis Suppurativa: A Retrospective Chart Review of 31 Patients.

BACKGROUND: Although a variety of medical and surgical interventions exist for the treatment of hidradenitis suppurativa (HS), it remains a challenging disease to manage because of its variable presentation and unpredictable clinical course. Apart from the combination of clindamycin and rifampin, the success of other combination therapies is largely unknown.

OBJECTIVES: The goal of our study was to examine the clinical utility of various combination therapies for the treatment of HS.

METHODS: We conducted a qualitative retrospective chart review of 31 patients with dermatologist-diagnosed HS who were seen at an academic teaching hospital between 2014 and 2018. Demographic data, disease location, disease severity, and treatment protocol were retrieved for analysis. Hurley stage was used to classify disease severity on initial presentation, and the International Hidradenitis Suppurativa Severity Score System (IHS4) was used to track changes across visits.

RESULTS: Of the 31 patients (Mage = 37.7 years; 67.7% female) included in the study, 6 (19.4%), 11 (35.5%), and 14 (45.2%) patients were classified as Hurley stages I, II, and III, respectively. Although no statistical results are provided because of the small sample size, we have identified several drug combinations that show promising clinical response for patients with HS based on their IHS4 score, such as isotretinoin/spironolactone for mild disease, isotretinoin or doxycycline with adalimumab for moderate disease, and cyclosporine/adalimumab for severe disease.

CONCLUSIONS: This preliminary work demonstrates that HS treatment with combination therapy appears to be a promising method of disease management.
