In chapter 2 of Japanese Pediatric Guideline for The Treatment and Management of Asthma (JPGL) 2020, the definition, pathophysiology, diagnosis, and severity classification of childhood asthma are described. In this revision, the definition of childhood asthma was revised, and a figure/description of the pathophysiology of childhood asthma with emphasis on type 2 airway inflammation, a diagram related to the differentiation of asthma, and a column on vocal cord dysfunction, which is essential in differential diagnosis, were added. Besides, descriptions that is duplicated in other chapters were deleted from this chapter. Understanding the pathophysiology of childhood asthma and making an appropriate differential diagnosis are important steps in the correct diagnosis, treatment, and management of childhood asthma. In this article, we explained the changes from JPGL2017 in chapter 2 of JPGL2020.
