Author(s): Denny G, Anadkat MJ

BACKGROUND: Treatment for hidradenitis suppurativa is often empiric and inadequate, and determining which patients will respond is difficult.

OBJECTIVE: We sought to determine which patient factors are associated with a positive response to first-line medical therapy.

METHODS: A single-center retrospective cohort study of all patients with hidradenitis suppurativa seen between January 1, 1992, and October 1, 2014, was conducted. Response to first-line medical therapy (oral/topical antibiotics, intralesional corticosteroids, and topical washes) was examined at follow-up within 6 months of initiating therapy. A multivariate binary logistic regression model was built examining response to treatment and the interplay of patient factors and treatment initiated.

RESULTS: In all, 198 patients were included in the final model. Nonsmokers (odds ratio 2.634, 95% confidence interval 1.301-5.332, P = .007) and older individuals (odds ratio 1.046 for each additional year, 95% confidence interval 1.020-1.072, P < .001) were more likely to have improvement at follow-up. In addition, current smokers differed significantly from nonsmokers in several regards.

LIMITATIONS: The retrospective nature of this study is a limitation, as is relying on classification of disease severity from physical examination findings in some patients.

CONCLUSIONS: The results of this study suggest that clinicians may be able to more accurately predict which patients with hidradenitis suppurativa will respond to first-line medical therapy, and which patients may require therapy escalation.
