Gut Microbiota Modulation in the Management of Chronic Obstructive Pulmonary Disease: A Literature Review

Abstract

Chronic obstructive pulmonary disease (COPD) represents a significant global health burden, characterized by progressive airflow limitation and exacerbations that significantly impact patient morbidity and mortality. Recent research has investigated the interplay between the gut and the lungs, known as the gut-lung axis, highlighting the role of the gut microbiome in COPD pathogenesis. Dysbiosis, characterized by microbial imbalance, has implications for COPD, influencing disease progression and susceptibility to exacerbations. This comprehensive review integrates current scientific literature on gut microbiota modulation as a therapeutic avenue for COPD management. Through a thorough discussion of studies investigating probiotics, prebiotics, synbiotics, antibiotics, dietary fiber, and fecal microbiota transplantation, this review summarizes the influence of these interventions on COPD via the gut-lung axis through the modulation of systemic inflammation, mucosal immunity, and metabolic processes. The interventions highlighted here show potential in preventing COPD exacerbations, preserving lung function, and improving patient quality of life. By compiling the latest scientific evidence, this review provides a comprehensive framework for physicians and researchers to deduce the effectiveness of gut microbiome modulation as an adjunctive therapeutic strategy in COPD management.
