Objective To explore the characteristics of induced sputum microbiome in the patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods Induced sputum samples from 55 patients with AECOPD and 45 patients with stable COPD were analyzed by sequencing of 16S rRNA gene. Microbiota was measured by alpha diversity, beta diversity and LDA effect size analysis (LefSe).Results The microbiome diversity of induced sputum in the AECOPD group was lower than that in the stable COPD group. The microbiome richness in the AECOPD group was higher than that in the stable COPD group. The microbiome structure changed in the AECOPD group compared with the stable COPD group. The proportion of some common pathogens got enriched. The levels of hypersensitive C reactive protein (hs-CRP), interleukin-8 (IL-8), tumor necrosis factor alpha (TNF-α) and Global Initative for Chronic Obstructive Lung Disease (GOLD) grade were negatively related to the diversity of microbiome in the AECOPD group.Conclusions The microbiome diversity of induced sputum in AECOPD patients is decreased, and is negatively correlated with the levels of hs-CRP, IL-8, TNF-α and GOLD grade. There are differences in the microbiome structure between AECOPD and stable COPD patients. Some enrichment of common pathogens are found in the induced sputum of patients with AECOPD. These results suggest that there is a significant bacterial dysbiosis in patients with AECOPD.
