Although it is difficult to find a cause of chronic urticaria in children, previous studies have been identified some triggers, such as autoimmunity, physical stimuli, food and its additives, and infection. History taking and physical examination remain the best tool for identifying an underlying cause of urticaria. First investigations include a complete blood count with differential, erythrocyte sedimentation rate, and C-reactive protein in children with chronic urticaria. If physical stimuli are suspected as triggers of chronic urticaria, appropriate provocation tests can be performed. Although the frequency of autoimmune urticaria was relatively high compared to the other causes in children with chronic urticaria, it is not easy to apply routine use of autologous serum skin tests to clinical practice. Additional extensive laboratory investigations are not required in the majority of cases. Second-generation H1-antihistamines are the mainstay of treatment from current guidelines in children with chronic urticaria, and dosage can be increased if the standard dose is not effective. Data on chronic urticaria in children are scarce, and causes have been considered to be similar to those in adults. Therefore, diagnostic approaches and treatment principles of chronic urticaria in children have been derived from extrapolating data in adults. In the future, comparative studies for the causes of chronic urticaria between children and adults, and therapeutic modalities for refractory cases will be needed.
