RESUMO
We conducted a retrospective data analysis of 26 patients with chronic spontaneous urticaria (CSU), 12 of whom had been treated with anti-IgE therapy (omalizumab). The subcohort of patients treated with omalizumab displayed more severe and prolonged courses of disease. In addition, they had often undergone various inpatient therapies, frequently presenting with concomitant angioedema. Collecting the Urticaria Activity Scores from the seven daily values for wheals and itching (UAS7) proved an important and suitable instrument for the determination and assessment of the course of therapy in the dermatological office. Elaborate laboratory screenings, however, seem far less indicative of the severity, prognosis and course of the disease. Omalizumab proved to be a viable and well-tolerated treatment option. One third of the patients were completely free of all symptoms, another third showed very good improvement, whereas the last third showed no improvement at all, even when omalizumab and/or concomitant therapies were escalated.
