Objective:

Several case-reports describing successful response to TNF-a antagonists in patients with hidradenitis suppurativa (HS), especially with infliximab and etanercept, have been reported. However, most of them had a short follow-up, showed limited efficacy and/or unacceptable side effects. Our aim was to evaluate the efficacy and safety of adalimumab therapy in 18 patients with refractory HS.

Methods:

All of them fulfilled the following criteria: (1) HS resistant to standard medical treatments; (2) lack of response to at least 1 systemic immunomodulating drug; (3) multifocal active HS. In all cases Adalimumab therapy (40 mg subcutaneously every-other-week) was started. If HS was not adequately controlled, adalimumab dosage was increased up to 40 mg/week. If persistent clinical remission was achieved adalimumab therapy was gradually decreased to a minimum dose of 40 mg every 3 weeks. Quality of life was assessed using the Dermatology Life Quality Index (DLQI).

Results:

18 patients (9W:9M) (mean age, 45.17±15.8 years) with severe HS (mean disease duration, 19.83 ± 17.3 years) were studied. In 6 patients HS was associated with other conditions; SLE (2 cases), rheumatoid arthritis (2 cases), idiopathic monoarthritis (1 case), and psoriasis (1 case). Five patients had initially been treated with infliximab and 1 with etanercept. All these 5 patients were switched to adalimumab due to inefficacy. At 1st month 13, 4 and 1 patient achieved high, moderate and none improvement in suppurative symptoms, respectively. The 6 patients with associated diseases also experienced improvement of these conditions. After a mean follow-up of 92 ± 88 weeks adalimumab efficacy was maintained. Adalimumab was well-tolerated. The most frequent side-effect was mild to moderate pain at injection site, and only 1 patient developed a severe facial skin reaction.

Conclusions:

Adalimumab seems to be an effective and safe treatment in refractory HS. These promising results warrant the need of prospective controlled study.
