Abstract

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.
