[Adverse reactions during biological therapy for psoriasis: results of a survey of the Spanish Psoriasis Group]. / Efectos adversos observados durante la terapia biológica en la psoriasis. Resultados de una encuesta al Grupo Español de Psoriasis.

BACKGROUND: Biologic therapies have been a major breakthrough in the treatment of psoriasis because they are more selective and have a better short-term and medium-term safety profile. There are reliable data to support both the efficacy and the safety of these drugs. However, it is always useful to report the clinical experience of dermatologists who are experts in the use of biologic agents to treat psoriasis, particularly with regard to their safety. MATERIAL AND METHODS: We present the results of a survey administered to the members of Spanish Psoriasis Group and based on a series of questions referring to the clinical safety of these agents. A total of 988 patients treated with efalizumab, infliximab, etanercept, and adalimumab were reported by 15 members of the group. RESULTS: There was a particularly high proportion of reactions (34%) to infliximab infusions. Blood test abnormalities were detected in 13.25% of patients and infections in 12.24%, with one case of pulmonary tuberculosis. Attention is drawn to the adverse effects profile of efalizumab: de novo arthritis in 5.8% and rebound in 20.9% of patients. CONCLUSION: The safety data provided by our study should be taken into account in view of the large number of patients recruited by dermatologists experienced in the use of this type of therapy.

Introducción: La terapia biológica ha representado un avance muy importante en el tratamiento de la psoriasis, al tratarse de una generación de fármacos más selectivos y con mejor perfil de seguridad a corto y medio plazo. Existen datos sólidos a favor de la eficacia de cada uno de estos fármacos, así como de su seguridad. A pesar de ello, siempre es útil aportar la experiencia clínica de dermatólogos expertos en el tratamiento de la psoriasis con biológicos, en especial en lo referente a su seguridad. Material y métodos: Se realizó una encuesta a los miembros del Grupo Español de Psoriasis (GEP) basada en una serie de ítems relativos a aspectos referentes a la seguridad clínica de estos fármacos, cuyos resultados se presentan en este artículo. Un total de 988 pacientes tratados con efalizumab, etanercept, infliximab y adalimumab fueron recogidos por parte de 15 miembros del GEP. Resultados: Entre los resultados obtenidos destaca la elevada proporción de reacciones a infliximab (34%). Se observaron alteraciones analíticas en el 13,25% de los pacientes e infecciones en el 12,24%, con un único caso de tuberculosis pulmonar. Es de destacar el perfil de efectos secundarios de efalizumab: artritis de novo en el 5,8% y rebote en el 20,9%. Conclusión: Los datos de seguridad aportados por nuestro trabajo deben tenerse en consideración, habida cuenta del importante número de pacientes reclutados por un grupo de dermatólogos expertos en el manejo de este tipo de fármacos (AU)
