[Chronic urticaria. Prevalence, course, prognostic factors and impact].
Chronic urticaria (CU) is one of the most frequent diseases in the field of dermatology. Recent studies have shown a point prevalence between 0.5 and 1% in the total population with a predominance of females. In general, all age groups and all classes of the population can be affected. An incidence peak has been found in the third and fourth decades. According to the current guidelines, CU is characterized by the spontaneous occurrence of wheals and/or angioedema for more than 6 weeks. However, epidemiological studies have revealed that the majority of patients suffer for several months, or frequently years. Disease duration is likely to be longer in case of angioedema, a combination with physical urticaria, positivity in the autologous serum skin test (autoreactivity) and a high disease severity. Studies on the impairment of quality of life have been shown that many CU patients suffer as strong from their disease as patients with coronary artery disease. Apart from pure physical symptoms, patients experience restrictions in daily life activities and social life. In addition, sleep disturbances are common and CU patients frequently exhibit psychiatric comorbidities. To avoid frustration in care, it is important to perceive all different dimensions of CU that impact the patient's life and to take the patients and their disease seriously. The aim of therapy should be to obtain total symptom control.
