Comparison and review of international guidelines for treating asthma in children.

Abstract

Asthma, the most common chronic disease, is characterized by airway inflammation and airflow obstruction. The World Health Organization estimates that approximately 300 million people worldwide have asthma, 30% of whom are pediatric patients. Asthma is a major cause of morbidity that can lead to hospitalization or death in severe pediatric cases. Therefore, it is necessary to provide children with objective and reliable treatment according to consistent guidelines. Several institutes, such as the Global Institute for Asthma, National Heart, Lung, and Blood Institute, British Thoracic Society, Japanese Society of Pediatric Allergy and Clinical Immunology, and Korean Academy of Asthma, Allergy, and Clinical Immunology have published and revised asthma guidelines. However, since recommendations differ among them, confusion persists regarding drug therapy for pediatric asthma patients. Additionally, some guidelines have changed significantly in recent years. This review investigated the latest changes in each guideline, compared and analyzed the recommendations, and identified the international trends in pediatric asthma drug therapy. The findings of this review may aid determinations of the future direction of the Korean guidelines for childhood asthma.
