Abstract

BACKGROUND

Sitosterolemia is a rare autosomal recessive genetic lipid metabolism disorder characterized by high concentrations of plant sterols in plasma and tissues, which can cause a variety of clinical symptoms, such as xanthomatosis, atherosclerosis, and arthritis. In recent years, more and more scholars have begun to pay attention to the special disease of sitosterolemia. Bibliometric analysis, as a method of quantitative analysis of scientific literature, can help us systematically understand the research status and development trends in this field. In this study, CiteSpace software was used to analyze the literature on sitosterolemia.

SOURCES OF MATERIAL

Publications on sitosterolemia were collected from the Web of Science Core Collection (WOSCC) and PubMed. The bibliometric tools CiteSpace software and Microsoft Excel were used to identify the historical features, the evolution of active topics, and emerging trends in the sitosterolemia field.

ABSTRACT OF FINDINGS

A total of 885 publications were retrieved and 416 publications were included in the analysis after the removal of duplicates. From 1974 to 2024, the number of publications and the related citations show an obvious fluctuating trend. The top 3 institutions with the most publications were the University of Bonn, the University of Texas System, and the University of Texas Southwestern Medical Center Dallas; the top 3 authors with the most publications were Patel SB, Tada H, and Salen G. The research hotspots on sitosterolemia mainly focus on phytosterols, whole exome sequencing, and lipid metabolism. The top 5 keywords by frequency of occurrence were "sitosterolemia," "humans," "dietary-cholesterol," "cholesterol," and "absorption." There is extensive scientific research cooperation among the sitosterolemia research institutions. Genetic research remains an important and ongoing area of interest in the study of sitosterolemia, given the fundamental role of genetic mutations in the disease's pathogenesis.

CONCLUSION

The findings based on the bibliometric studies provide the current status and trends in sitosterolemia research and may help researchers identify hot topics and explore new research directions in this field.
