Global Research Trends on Endothelial Glycocalyx in Sepsis: A Bibliometric Analysis.

BACKGROUND

Sepsis remains a major global health challenge, with glycocalyx dysfunction playing an important role in its pathogenesis. Recent research highlights EG degradation as a key contributor to vascular permeability, inflammation, and organ failure. Despite growing interest, a comprehensive bibliometric analysis of global research trends on EG in sepsis is lacking.

METHODS

We conducted a bibliometric analysis using data from Web of Science and Scopus (2005-2025). Inclusion criteria were original English-language research articles. Bibliometrix R-package was employed to analyze publication trends, citation metrics, collaboration networks, and keyword co-occurrence.

RESULTS

Among 217 publications, research output increased 13-fold (2005-2023), with Shock and Critical Care as leading journals. The United States, Japan, and Australia were top contributors, with strong international collaborations. Key themes included EG biomarkers, microcirculatory dysfunction, and therapeutic strategies. Emerging trends involved COVID-19-associated EG injury and novel imaging techniques.

CONCLUSION

This study maps the evolution of EG research in sepsis, highlighting exponential growth, key contributors, and thematic shifts. Future directions include validating EG biomarkers, developing targeted therapies, and enhancing global research equity.
