Abstract

Introduction

Acute kidney injury (AKI) is a global disease with high morbidity and mortality. At present, the treatment of AKI still lacks targeted measures. Ferroptosis, a form of regulated cell death, plays an essential role in the initiation and progression of AKI. Current evidence proves that targeting ferroptosis is supposed to be a novel potential strategy to cure AKI. In this study, we aim to use bibliometric analysis to identify research trends and hotspots in the field of “ferroptosis in AKI”.

Methods

We chose the Science Citation Index Expanded (SCI-EXPANDED) index of the Web of Science Core Collection (WoSCC) as the source database for data retrieval. Data were retrieved from the WoSCC on May 24, 2022. Full records and cited references of all the documents in WoSCC were collected. The R software and the Online Analysis Platform of Literature Metrology were used for data analysis and visual analysis.

Results

There were 120 documents on “ferroptosis in AKI” in the WOSCC from 2014 to 2022 (May 24, 2022). There was a clear upward trend each year in the number of documents published. According to WoS report, China, the United States, and Germany were the top three countries involved in this research area, the majority of publications were included in the subject area “Cell Biology”. Technical University of Dresden contributed the most publications, followed by Central South University and University of Pittsburgh. The Journal of Cell Death and Disease had the highest H-index and contributed the most publications. Linkermann A authored 16 articles and had the highest H-index. Multifactorial analysis of the keywords show that the research field is divided into two clusters. The most contributing publications and the most cited publications were also determined by factorial analysis.

Conclusion

This bibliometric analysis provides a comprehensive analysis of research trends and hot spots on the topic of “ferroptosis in AKI”. The study of ferroptosis-related AKI research remains in its early stages. There will be a dramatically increasing number of publications on this field. Further research should focus on exploring the mechanisms of crosstalk between ferroptosis and other programmed cell deaths, and improves clinical applications and therapeutic effects against AKI.
