Key result
Research on omics in ulcerative colitis has increased rapidly since 2019, with the United States leading in publications and current hotspots including microbiome, transcriptomics, and metabolomics.
Why the study?
Although research on the omics of ulcerative colitis has drawn global attention, there is a lack of bibliometric analysis evaluating trends and hotspots in this field.
Bibliometric analysis reveals a rapidly increasing trend in omics research in ulcerative colitis since 2019, with the US leading in publications and collaborations, and hotspots including microbiome, transcriptomics, and metabolomics.

Rapid post-2019 growth in ulcerative colitis omics research extends the evidence base; leaves open whether hotspots will yield practice-changing insights.
Background: Omics has emerged as a promising biological science to shed light on the etiology, pathogenesis, and treatment of ulcerative colitis (UC). At present, although research on the omics of UC has drawn global attention, there is still a lack of bibliometric analysis in this field. This study aimed to access the trends and hotspots of omics in UC research. Method: Publications related to omics in UC from 1 January 2000 to 15 October 2022 were retrieved from the Web of Science Core Collection database. VOSviewer, CiteSpace, and the online bibliometric analysis platform "Bibliometrix" were adopted to extract and visualize information. Results: A total of 385 publications were finally included and the annual number of publications fluctuated. The trend in publications increased rapidly after 2019. The United States showed its dominant position in several publications, total citations, and international collaborations. The top five research organizations for publications on the research of omics in UC were Harvard Medical School, the Icahn School of Medicine at Mount Sinai, Karolinska Institutet, the Brigham and Women's Hospital, and the Massachusetts General Hospital. Ashwin Ananthakrishnan from the Massachusetts General Hospital was the most productive author, and Séverine Vermeire from the Catholic University of Leuven was co-cited most often. Inflammatory bowel disease was the most popular and co-cited journal in this field. The reference with citation bursts and trend topics showed that "ulcerative colitis," "inflammatory bowel disease," "microbiome," "transcriptomics," "genomics," "metabolomics," "proteomics," "dysbiosis," "biomarkers," "loci," and "therapy" are currently research hotspots. Conclusion: Our study presents several important insights into the research trends and developments in the field of omics in UC, which will provide key information for further research.

Zhang et al. (2023) conducted a review in Ulcerative colitis (n=385). Omics research was evaluated on Bibliometric trends and hotspots. Research on omics in ulcerative colitis has increased rapidly since 2019, with the United States leading in publications and current hotspots including microbiome, transcriptomics, and metabolomics.
