Obstructive Sleep Apnea-hypopnea Syndrome and Severe Asthma: Advances and Challenges

Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) and asthma are two prevalent chronic respiratory diseases. Recent research has revealed that OSAHS not only shares several common risk factors with asthma but also exhibits a high comorbidity rate with it. This mutual interaction complicates the course of both diseases and increases complexity to clinical diagnosis and treatment. This review aims to provide a comprehensive summary and analysis, from an epidemiological and pathophysiological perspective, of the research progress and challenges concerning the OSAHS comorbided with asthma, particularly in severe asthma.
