Background: The EXPRESS study demonstrated the initial efficacy of infliximab in psoriasis affecting the skin and nails. Objective: To further assess how patients with a positive initial response to infliximab respond to 1 year of continuous infliximab treatment. Methods: A retrospective analysis of patients with moderate-to-severe plaque and nail psoriasis who initiated and continued infliximab treatment up to week 46 was conducted. Results: Among all nail psoriasis patients receiving 1 year of infliximab (n = 186), 74.6 and 54.1% achieved at least 75 or 90% improvement in the Psoriasis Area and Severity Index (PASI) at week 50. These PASI-75 (n = 138) and PASI-90 (n = 100) responders had respective mean improvements from baseline to week 50 of 93.6 and 97.3% for the PASI, 90.6 and 94.1% for the Dermatology Life Quality Index (DLQI) and 78.2 and 80.3% for the Nail Psoriasis Severity Index (NAPSI). Conclusions: Infliximab treatment for 1 year produced sustained improvement in PASI, DLQI and NAPSI scores. Copyright © 2010 S. Karger AG, Basel.
