Bronchial asthma and chronic obstructive pulmonary disease (COPD) are conditions with unique pathophysiological mechanisms and clinical symptoms, airway obstruction being a shared characteristic of both. Concomitant asthma and COPD (Asthma-COPD Overlap, ACO) is not a separate disease, but represents several variously overlapping phenotypes and endotypes of asthma and COPD. The prevalence of ACO according to population studies ranges from 0.9% to 11.1%, 11.1-61.0% in patients with asthma and 4.6-66% in patients with COPD. The diagnosis of ACO presents difficulties for clinical practitioners due to a lack of universal definition and specific biomarkers of the condition, as well as a wide spectrum of phenotypes. The article considers modern concepts of phenotypes, endotypes, ACO biomarkers, an overview of ACO, patient stratification approaches for choice of optimal therapy.
