Abstract:

Objective To analyze the global research hotspots and emerging trends in English-language literatures reporting microecology of chronic obstructive pulmonary disease (COPD). Methods Articles reporting microecology of COPD from 2014 to 2024 were searched in the Web of Science Core Collection database. VOSviewer and Citespace tools were employed for co-authorship, co-citation, and co-occurrence analyses of countries, institutions, authors, references, and keywords, which were finally visualized. Results A total of 1, 492 articles were included in the analysis. Overall, there was an annual increase in the publication volume, with the United States leading in the publication output. Dave Singh was identified as the most productive author, while Sanjay Sethi had the highest citation frequency. Int J Chron Obstruct Pulmon Dis was noted as a significant academic publication in this field. Based on the analysis of references and keywords, the lung microbiome and gut microbiome were identified as major research hotspots in the future. Conclusion Microecology research in COPD is flourishing. It is essential for Chinese investigators to enhance international exchanges and cooperation, focusing on prospective clinical studies and the exploration of advanced laboratory techniques.
