Summary
Asthma-COPD overlap syndrome (ACOS) presents a diagnostic challenge, often leading to worse outcomes than asthma or COPD alone. This review proposes practical diagnostic and management strategies for ACOS.
Area of Science:
- Pulmonology
- Respiratory Medicine
- Clinical Medicine
Background:
- Asthma-COPD overlap syndrome (ACOS) is defined by persistent airflow limitation with features of both asthma and COPD.
- ACOS represents a potential phenotype within the spectrum of chronic obstructive airway diseases.
- The prevalence and clinical impact of ACOS are significant, with patients experiencing more adverse outcomes and higher healthcare resource utilization compared to isolated asthma or COPD.
Purpose of the Study:
- To review current diagnostic criteria for ACOS.
- To propose practical approaches for diagnosing and managing ACOS.
- To identify key research questions for future ACOS studies.
Main Methods:
- Literature review of diagnostic criteria for ACOS.
- Synthesis of existing evidence to propose diagnostic and management strategies.
- Identification of research gaps and future directions.
Main Results:
- Diagnostic criteria for ACOS vary, leading to inconsistent prevalence estimates.
- No specific biomarkers currently exist to differentiate ACOS from asthma or COPD.
- Management requires individualized approaches tailored to patient-specific needs.
Conclusions:
- ACOS poses a diagnostic challenge for clinicians due to overlapping features and lack of specific biomarkers.
- Individualized management strategies are crucial for optimizing treatment efficacy and minimizing side effects in ACOS patients.
- Further research is needed to refine diagnostic criteria and therapeutic approaches for ACOS.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...

4.9K
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.
Critical processes in asthma pathophysiology include:

COPD is defined as a heterogeneous lung condition marked by persistent respiratory symptoms such as dyspnea, cough, and sputum production, caused by abnormalities in the airways that cause airflow obstruction.
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
