Abstract:

Objective: This study employs bibliometric analysis to examine the literature on latent tuberculosis infection (LTBI), with the goal of providing researchers with a comprehensive understanding of the current research landscape and future trends. Methods: The analysis was conducted using the expanded version of the Science Citation Index in the Web of Science Core Collection database, with the search field set to the topic. The primary keywords included ‘Latent Tuberculosis’ ‘Latent TB’ and ‘LTBI’. The literature search was conducted on May 13, 2024, and the publication period was restricted to 2014—2023. Only original research articles and review papers published in English were included, resulting in a total of 4210 relevant publications. VOSviewer software was employed to visualize the data and perform an in-depth analysis of the LTBI research field, focusing on publication trends, journal analysis, highly cited papers, international research collaboration networks, and keyword clustering. Results: Since the World Health Organization introduced its LTBI strategy in 2015, the topic has garnered sustained attention from the global academic community. From January 2014 to December 2024, we identified 4210 relevant articles, which collectively received 74324 citations, averaging 17.65 citations per article. The United States led in the number of publications (1314 articles, 31.21%), followed by China (587 articles, 13.94%). Analysis of international research cooperation networks revealed that latent tuberculosis infection research is marked by close collaboration among countries and regions, with the United States, China, the United Kingdom, India, and Italy taking leading roles. Keyword clustering indicated that the primary research focuses in this field currently include immunological mechanisms, comprehensive management, LTBI in the context of rheumatic diseases, and LTBI screening. Conclusion: This study highlights the current research landscape and future trends in the field of LTBI, offering valuable insights and references for research institutions and scholars.
