Özet

Introduction: Urticaria is a condition that is characterized by the development of wheals (hives), angioedema, or both. If symptoms persist for less than 6 weeks, it is classified as acute urticaria (AU), and if they persist for longer than 6 weeks, it is classified as chronic urticaria (CU). Disease activity is evaluated using validated patientreported outcome measures (PROMs) such as the 7-day urticaria activity score (UAS-7) and urticaria control test (UCT). In this study, we aimed to determine whether there was a difference between patients with chronic and recovered urticaria in terms of age, sex, symptoms, disease severity, disease control, and triggering factors by following patients with AU for 6 months. Methods: The routine tests were requested at the first admission of the patients. If previously examined, anti-thyroid peroxidase (anti-TPO), anti-nuclear antibody, etc., were recorded. After the first examination, the patients were evaluated again using a visual analog scale (VAS), UCT, UAS-7, and medication scores (MSs) in the 1st, 3rd, and 6th months. Results: One hundred nine (F/M: 80/29) patients were included in the study. Twenty-seven patients had a previous history of AU, 22 of these patients were evaluated as having recurrent AU, and five became chronic during follow-up. Urticaria continued in 22 of 82 patients who presented with firstattack AU in the 3rd month and 17 in the 6th month. We had a chronicity rate of 24.7%. It was determined that having positive anti-TPO increased the risk of CU 1.69 times. A statistically significant improvement was found in the mean VAS, UCT, UAS-7, and MSs evaluated in the 1st, 3rd, and 6th months of patients with CU compared with baseline. Conclusion: AU is a common disease and usually heals in a short time without becoming chronic. Studies on the causes of chronicity are limited. Testing anti-TPO in patients presenting with AU may be useful in terms of disease course and risk of chronicity.
