RESUMO
Se presentan 3 pacientes con urticaria solar que o no habían respondido adecuadamente o presentaban limitaciones a los tratamientos de primera línea (antihistamínicos H1 a dosis altas o fototerapia), que fueron tratados con omalizumab. Dos de ellos mejoraron clínicamente con un aumento muy importante de la tolerancia a la luz, uno de ellos con clara mejoría de la calidad de vida. El otro paciente no mejoró y desarrolló una reacción local leve a la medicación inyectada. Omalizumab puede ser por tanto una alternativa terapéutica potencialmente útil y segura en urticarias solares graves no respondedoras al tratamiento convencional (AU)
We report 3 cases of solar urticaria in which there was no response or limited response to first-line treatments with high-dose H1 antihistamines or phototherapy. The patients were then treated with omalizumab. Symptoms improved in 2 patients, whose tolerance to sunlight increased considerably; quality of life clearly improved for 1 of these patients. The third experienced no improvement and developed a mild local reaction to the injected medication. We conclude that omalizumab may offer a potentially safe, useful alternative for patients with solar urticaria who do not respond to conventional therapy (AU)
