Although there are basic similarities between adult asthma and childhood asthma in terms of etiology, epidemiology, immunology, pathogenesis, pathophysiology, and clinical principles of diagnosis and treatment, it should be fully understood that children are not just “little adults” or a “miniature of adults However, it should be fully understood that children are not just “small adults” or a “microcosm of adults”. Asthma in children is still very different from asthma in adults in some aspects. Because children are in the process of continuous intellectual, physical, immunological, and psychological growth and development, they have dynamic characteristics of continuous development and improvement, especially in the areas of immunology and pathophysiology. Therefore, children’s asthma has its own special characteristics and is different from adult asthma in many ways. Pediatricians should make full use of the dynamic characteristics of children in development and continuous improvement, and active prevention and treatment can achieve clinical cure and also prevent childhood asthma from developing into severe asthma with airway remodeling.
