Phenotypes of Asthma-Chronic Obstructive Pulmonary Disease Overlap

Muhammad Adrish et al. Immunol Allergy Clin North Am. 2022 Aug.

Abstract

Asthma and chronic obstructive pulmonary disease are considered unique diseases with distinct characteristics. Asthma-chronic obstructive pulmonary disease overlap is a disorder in which the clinical characteristics of asthma and chronic obstructive pulmonary disease coexist. Asthma-chronic obstructive pulmonary disease overlap is a heterogenous condition; patients can have varied clinical presentations. There are significant gender variations among different phenotypes overlap. Age of symptom onset is another important consideration. Severity of symptoms, spirometry findings, smoking history, and type of airway inflammation varies between the different phenotypes. Understanding disease pathophysiology and establishing phenotypic models will improve a precision approach.

Keywords: Asthma; Asthma COPD overlap; COPD; Phenotype.
