Background. Etanercept is one of the new biologic agents available for treating psoriasis. It has proved an effective option in a high percentage of patients, leading to sustained improvements in the psoriasis area severity index (PASI). Likewise, it is effective at controlling psoriatic arthritis, and its safety profile is excellent, with a much lower specific organ toxicity than traditional drugs and few side effects. Many of the data published to date are derived from clinical trials with this medication, but further studies are needed on the use of this therapy to manage patients in daily clinical practice. Methods. This was a retrospective observational study of 36 patients with psoriasis who received etanercept between March 2004 and March 2006. We describe the experience of using this agent at our hospital, with the clinical outcomes and the problems we have faced. Results. The PASI score was assessed before treatment and at 3 and 6 months of patient follow-up. After 3 months of treatment, 13 patients (36.11 %) had achieved a 50 % improvement in PASI score (PASI(50)), and 16 patients (44 %) had achieved a 75 % improvement (PASI(75)). Two of the patients (5.56 %) experienced an improvement in their disease without reaching PASI50 and only 4 patients (11.11 %) did not show clinical improvement or deteriorated. After 6 months, efficacy improved, with 27 patients (75 %) achieving PASI75, 6 patients (16.67 %) achieving PASI50, and 2 patients (5.56 %) showing no benefit from treatment. After 6 months, 13 of the patients (36.1 %) had achieved a 90% improvement in PASI score. No adverse events of sufficient significance to warrant discontinuation of treatment were reported. At present, 11 of the patients remain on etanercept treatment as efficacy has been sustained and they have not experienced any adverse events of note. Conclusions. Our clinical experience with the use of etanercept for treating plaque psoriasis shows a favorable efficacy and safety profile. We propose a standardized procedure for consultations with psoriasis patients involving extensive data collection on each visit and the creation of a national surveillance system for patients under treatment with biologic agents.
