The study investigates the frequency of inducible urticaria (IU) in patients with chronic spontaneous urticaria (CSU) and identifies factors influencing this prevalence.
Among 245 CSU patients, 75.9% reported physical triggers, but only 36.3% tested positive for IU, with symptomatic dermographism being the most common.
Results suggest that geographical differences affect IU prevalence, and factors like atopy and self-reactivity significantly contribute to CSU development.
