Methods: This cross-sectional study assessed patients with chronic urticaria followed up in a tertiary hospital. The CU-Q2oL contains 23 questions, with scores from 1 (no complaints) to 5 (many complaints). We consider the scores ≥ 3 as poor quality of life. They were classified into two groups: A – those patients who respond to antihistaminics (AH1), and B – others medications beyond the AH1. We considered the difference between (B-A) ≥ 1 in each question, as relevant. The groups were assessed about the duration of disease ≥ 10 years.
Results: Sixty-one patients participated in the study, of these, 58 (95%) were female and the mean age was 41 years. The average of the CU-Q2oL score was 72.5 for group B and 57.2 for group A. When we evaluated the time of disease ≥ 10 years, group A had 37% comparing to group B, 56%. The difference between groups B and A ≥ 1 was observed for the following issues: 3, 15, 17, 19 20, 21.
Conclusions: These results showed that the group with recalcitrant CU (group B) had urticaria for a longer time and a higher score for CU-Q2oL. Among the issues, those that were more important were related to social relationships, diet and side effects of medicines.
