The research on the treatment of primary immunodeficiency diseases by hematopoietic stem cell transplantation: A bibliometric analysis from 2013 to 2022

Hematopoietic stem cell transplantation (HSCT) is curative in patients with primary immunodeficiency syndrome. The safety and efficacy of HSCT as a therapeutic option for primary immunodeficiency diseases (PID) have been studied by many research groups. The purpose of our study was to perform a bibliometric analysis of research on HSCT for the treatment of PID, to assess research trends in this field, and note future research priorities. The Web of Science Core Collection (WOSCC) was used to identify relevant publications. VOSviewer and CiteSpace software were used to analyze bibliometric parameters, such as yearly records, authors, grouped authors, countries, institutions, categories and keywords. There are 602 relevant records for the last decade (2013–2022). The top 5 productive authors and high-quality paper journals are listed. Reference co-citations analysis demonstrated recent research trends were “inborn errors of immunity,” “gene editing,” and “enteropathy.” Research on HSCT for the treatment of PID has increased rapidly in the last decade, and bibliometrics are valuable for researchers to obtain an overview of hot categories, academic collaborations and trends in this study field.
