Research trends and emerging topics in gut microbiota-derived metabolites and diabetic kidney disease: a multi-database bibliometric analysis (2014-2025)

Objective

Diabetic kidney disease (DKD) is a leading cause of end-stage renal disease. The gut-kidney axis has highlighted the potential involvement of gut microbial metabolites in the development and progression of DKD. This study aimed to systematically characterize the knowledge structure, research hotspots, collaboration networks, and emerging trends at the intersection of DKD and gut microbial metabolites from 2014 to 2025 using a multidatabase bibliometric approach.
