Interrelationship Between Obstructive Sleep Apnea Syndrome and Small Airway Disease: A Comprehensive Review.

Area of Science:

• Respiratory Medicine
• Sleep Medicine
• Pulmonology

Background:

• Obstructive sleep apnea syndrome (OSAS) involves upper airway obstruction, leading to fragmented sleep and systemic issues.
• Small airway disease (SAD) is characterized by inflammation and obstruction of smaller airways, impairing gas exchange.

Purpose of the Study:

• To explore the epidemiology, pathophysiology, risk factors, and diagnostics of OSAS and SAD.
• To emphasize the interrelationship between OSAS and SAD and their clinical management implications.

Main Methods:

• A comprehensive literature review was conducted.
• Examined shared and distinct characteristics, risk factors, presentations, diagnostics, and management strategies for OSAS and SAD.

Main Results:

• Obesity, smoking, and age are identified as shared risk factors for both OSAS and SAD.
• Co-occurrence of OSAS and SAD exacerbates respiratory symptoms and increases comorbidity risk (e.g., pulmonary hypertension, heart failure).
• The interplay necessitates integrated diagnostic and therapeutic strategies.

Conclusions:

• Integrated management approaches are vital for improving patient outcomes in OSAS and SAD.
• Addressing shared risk factors and understanding the interplay between these conditions are key to optimizing care.
• Knowledge gaps exist in precise diagnostics and targeted therapies for personalized treatment.
