Background Several studies report the use of tumor necrosis factor (TNF- ) inhibitors in refractory hidradenitis suppurativa (HS), particularly infliximab and etanercept. However, very limited data have been reported for adalimumab, the newest fully human anti–TNF- monoclonal antibody. We evaluated the long-term efficacy and safety of adalimumab therapy in 6 patients with refractory HS. In the case of positive culture findings from any draining lesion, antibiotic therapy was administered for at least 2 weeks before initiating adalimumab therapy. Adalimumab (in 40-mg subcutaneous injections) was prescribed every other week. If the disease was inadequately controlled, the dosage was increased to 40 mg/wk. If HS was in persistent clinical remission, adalimumab therapy was gradually decreased to 40 mg every 3 weeks. Quality of life was assessed using the Dermatology Life Quality Index.
Observations Six patients (mean [SD] age, 39.3 [12.9] years) with severe HS (mean [SD] duration, 22.5 [11.7] years) were treated with adalimumab. Significant improvements after 1 month of treatment were seen in the Dermatology Life Quality Index; in the number of affected regions, nodules, and fistulas; and in the basic laboratory findings. Improvements were maintained for a mean (SD) follow-up of 21.5 (7.1) (range, 13-29) months. Adalimumab was well tolerated.
Conclusion Adalimumab appears to be an effective and safe treatment for refractory HS.
