Adalimumab in conjunction with surgery compared with adalimumab monotherapy for hidradenitis suppurativa: A Randomized Controlled Trial in a real-world setting

Abstract

Adalimumab, the only biologic registered for hidradenitis suppurativa, shows clinical response in up to 60% of patients, leaving many patients in need for other treatment options such as surgery. To compare the clinical effectiveness of adalimumab combined with surgery vs adalimumab monotherapy in patients with moderate to severe hidradenitis suppurativa. A pragmatic Randomized Controlled Trial was performed from August 2018 to July 2022. Primary outcome was the difference in mean International Hidradenitis Suppurativa Severity Score System reduction after 12months of treatment with the difference in mean Dermatology Life Quality Index reduction as a key secondary outcome. Thirty-one patients were included per arm. The mean International Hidradenitis Suppurativa Severity Score System at baseline was 23.9±10.7 in the surgery group and 20.9±16.4, in the monotherapy group. After 12months of treatment the surgery group had a significantly greater reduction in International Hidradenitis Suppurativa Severity Score System compared with the monotherapy group (-19.1±11.3 vs -7.8±11.8, P<.001). Moreover, the surgery group showed a greater reduction in Dermatology Life Quality Index after treatment compared with the monotherapy group (-8.2±6.2 vs -4 ± 7.7, P=.02). The study follow-up was too short to assess surgical recurrence rates. Combining adalimumab with surgery resulted in greater clinical effectiveness and improved quality of life after 12months in patients with moderate to severe hidradenitis suppurativa.
