BACKGROUND: Urticaria is a common disorder, estimated to affect 2.1 to 6.7% of children and adolescents, and is a frequent cause of emergency department (ED) admissions.
METHODS: The aim of this study was to retrospectively characterize the clinical features of children and adolescents with a diagnosis of urticaria, evaluated in a tertiary care pediatric ED between 2015 and 2019. Statistical analysis was performed using IBM SPSS Statistics®, version 27.0.
RESULTS: A total of 2254 episodes of urticaria were counted with 98.1% corresponding to acute urticaria (AU). A suspected trigger factor was identified in 51.6% of the episodes, namely infections (27.8%), drugs (9.9%) and food (7.6%). From these episodes, excluding infections, only 59.2% were referred to an Allergy Consultation for further study, with only 18.8% (drug) and 28.3% (food) confirmed as the AU trigger. Of the 43 episodes of chronic urticaria (CU), 79% were referred to consultation, with 23 being diagnosed with chronic spontaneous urticaria, 8 with inducible urticaria and 3 with both entities. Older age (p < 0.001), personal history of atopy (p = 0.019) and angioedema (p = 0.003) were factors associated with CU, while the presence of other accompanying symptoms (p = 0.007) was associated with AU. Older age (OR = 1.2; p < 0.001) and the presence of angioedema (OR = 2.7; p = 0.007) were identified as independent factors for CU.
CONCLUSION: The majority of episodes corresponded to AU. Infections were the main suspected trigger, followed by drugs and food, with an overall confirmation rate ranging from 18 to 30%, highlighting the importance of an allergologic follow-up evaluation.
