A Bibliometric Analysis of Research on Diabetes and Diabetic Kidney Disease: Emphasizing Biomarkers, International Collaboration, and Thematic Structure

Abstract

This bibliometric study analyzes global research trends on diabetic kidney disease (DKD) and biomarkers using data retrieved from the Scopus database, comprising 1,174 publications based on the keywords "Diabetic kidney disease" AND "Biomarker." The study employs VOS viewer software for network visualization and cluster analysis to identify key authors, countries, and thematic research clusters. The results highlight three main clusters: epidemiological and clinical risk factors, biological monitoring of DKD patients, and diagnostic biomarker validation. China and the United States dominate the publication landscape, reflecting substantial investments in biomedical research. Key authors such as Nelson, R.G. and Bjornstad, P. play central roles in advancing this field. This study underscores the multidisciplinary approach required to improve DKD diagnosis and management through biomarker development, with implications for personalized medicine and global collaboration. Further research is needed to develop clinically useful biomarkers that enhance personalized management of diabetic kidney disease.
