Abstract
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 (PASI50), and 16 patients (44%) had achieved a 75% improvement (PASI75). 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.

Resumen
Introducción

Etanercept es uno de los nuevos fármacos biológicos surgidos para el tratamiento de la psoriasis. Ha demostrado ser una opción eficaz en un alto porcentaje de pacientes, provocando mejoras en el PASI (Psoriasis Assessment and Severity Index) que se mantienen en el tiempo. Además, resulta igualmente adecuado para el control de la artritis psoriásica. Por otra parte, el perfil de seguridad es excelente, con una toxicidad órgano específica mucho menor que los fármacos clásicos y la aparición de escasos efectos secundarios. Muchos de los datos publicados hasta el momento proceden de los distintos estudios clínicos que se han realizado con esta medicación, pero se necesitan trabajos que reflejen la experiencia en la práctica clínica diaria con el manejo de esta terapia en condiciones normales.

Métodos

Estudio observacional, retrospectivo, en el que se recogen los 36 pacientes con psoriasis a los que administramos etanercept durante el período de tiempo comprendido entre marzo de 2004 y marzo de 2006. Exponemos la experiencia de nuestro centro en la utilización de este fármaco, con la evolución clínica y los problemas a los que nos hemos enfrentado.

Resultados

El PASI se evaluó antes de comenzar el tratamiento y a los tres y seis meses de seguimiento de los pacientes. A los tres meses de tratamiento 13 de los pacientes (36,11%) habían alcanzado el PASI 50, y 16 pacientes (44,44%) habían alcanzado el PASI 75. Dos de los pacientes (5,56%) experimentaron una mejoría de su psoriasis, sin alcanzar el PASI 50, y sólo 4 pacientes (11,11%) no mostraron mejoría clínica o incluso empeoraron. A los 6 meses se observó un aumento de la eficacia, con 27 pacientes (75%) que alcanzaron el PASI 75 y 6 pacientes (16,67%) que llegaron a obtener el PASI 50, 2 pacientes (5,56%) no mostraron ningún beneficio tras la terapia. A los 6 meses 13 de los pacientes (36,1%) habían alcanzado el PASI 90. En ninguno de los casos se presentaron acontecimientos adversos de importancia que obligaran a suspender el tratamiento. Once de los pacientes siguen en tratamiento con etanercept en el momento actual, ya que se ha mantenido la eficacia y no han presentado efectos adversos importantes.

Conclusiones

Exponemos nuestra experiencia clínica con la utilización de etanercept para el tratamiento de la psoriasis en placas, con un perfil muy favorable de eficacia y seguridad. Proponemos la estandarización de la visita clínica al paciente con psoriasis, con recogida exhaustiva de datos en cada visita y la creación de un sistema nacional de registro de datos de pacientes con tratamientos biológicos.
