Analysis of research trends and hotspots in the primary treatment of end-stage renal disease

There is a lack of bibliometric analysis in research regarding primary therapy for end-stage renal disease (ESRD). This study aims to analyze the literature on ESRD therapy published over the past decade to understand current conditions and study trends for future research. Data were collected from the Web of Science Core Collection (WOSCC) database. Tools like CiteSpace 6.2.R4, 6.1.R6, VOSviewer 1.6.18, and Bibliometrix R4.1.1 were used to reveal research trends and hotspots. In addition, KEGG/GO analysis examined the probable functionalities of genes implicated in ESRD therapy to guide future research. The bibliometric analysis presented in this paper indicates that the number of publications has remained relatively stable since 2013. The level of international collaboration is notably high, with the United States serving as the dominant research hub in this field. The University of California system is the most prolific institution, and Transplantation Proceedings is the most frequently published journal in this area. Kalantar-Zadeh, Kamyar is recognized as the most published and cited author. Keywords such as "secondary hyperparathyroidism," "uremic toxins," "cyclosporine," "mycophenolate mofetil," and "biomarkers" have seen a surge in interest recently, reflecting emerging research trends. Furthermore, inflammation and stem cell research have been identified as promising new therapeutic avenues for ESRD. This study identifies major areas, frontiers, and trends in research on primary treatments for ESRD, providing significant implications for future research.
