In 2011, the Comprehensive Diagnostic Criteria for IgG4-related disease was published in Japan. Organ-specific diagnostic criteria based on organ-specific findings were proposed and published by each of the related societies, and the diagnostic criteria for IgG4-related respiratory disease was published in 2015. Based on the revisions to the comprehensive diagnostic criteria in 2020 and the publication of the Classification Criteria, new diagnostic criteria for IgG4-related respiratory disease are presented. Emphasis has been placed on evaluating specific pathological findings and excluding other respiratory diseases. It is mentioned in the commentary that in cases with imaging findings suggestive of interstitial pneumonia with chronic fibrosis or poor response to steroid therapy, other possible diseases should be considered.

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.

Common Respiratory Disorders

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
