Omalizumab, an anti\u2010IgE antibody, has shown promise in adults but data on its use in children, especially those under 12, are scarce. This systematic review and meta\u2010analysis aim to evaluate the efficacy and safety of omalizumab in pediatric chronic spontaneous urticaria, providing insights to inform clinical practice and future guidelines. PubMed, Scopus, Embase, Cochrane, and Web of Science databases have been searched for relevant studies. The \u201cR\u201d software has been utilized to analyze the response and relapse rates, changes in urticaria scores, and adverse event rates. Subgroup analyses were also done based on response rate. The assessment of heterogeneity utilized the\n                    <jats:italic>I<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    and chi\u2010squared tests, applying the random effect model.

Adverse events occurred in 3.4% of patients, with specific events including urticaria, angioedema, headaches, fatigue, flu\u2010like symptoms, and mild joint pain. In pediatric patients under 12\u2009years, 18 out of 21 achieved complete response, with a median age of 8\u2009years and follow\u2010up durations between 4 and 18\u2009months. Adverse events in this group included serum sickness in one patient. Omalizumab appears to be an effective treatment option for chronic spontaneous urticaria, demonstrating effectiveness in improving symptoms and providing significant relief. The treatment is generally well\u2010tolerated, with adverse events being rare and manageable. Overall, omalizumab contributing to better disease management and quality of life.\n
