Abstract
Infliximab has shown promising results for the treatment of moderate to severe psoriasis and psoriatic arthritis. We conducted a retrospective study of all 52 patients treated with intravenous infliximab for severe psoriasis at a single practice site. These patients had recalcitrant plaque psoriasis (>33% body surface area), which was unresponsive to multiple conventional systemic therapies. Intravenous infliximab was administered at a dose of 5 mg/kg at 0, 2, 6, and 14 weeks and every 8 weeks thereafter. Patients were monitored for infections, infusion reactions, side effects, and response to therapy. Fifty-two patients (men = 32, women = 20) with a mean age of 47 (range, 22-76 years old) were included in this study. They were followed for a minimum of 4 months and a maximum of 33 months (median, 22 months). Patients received a mean total number of 12 infusions (range, 3-22). Forty-six of 52 patients (88%) had a clear or almost clear improvement based on the Physician's Global Assessment done by a single physician. Twelve patients (23%) required infliximab dose escalation to maintain control of their disease. Nine patients experienced infusion reactions. Thirteen patients experienced nonopportunistic infections; however, only one infection required temporary cessation of infliximab. This was a retrospective study at a single practice site. Infliximab was extremely effective and well tolerated in this group of patients with severe, recalcitrant psoriasis. Thirty-nine of 52 patients have continued receiving treatment for a median duration of 25 months with excellent disease control. Infliximab can provide control of extensive psoriasis with continued intermittent infusions.
