Mapping theme trends and knowledge structure of Sjögren's syndrome (SS), a bibliometric analysis from 2010 to 2021

Research hotspots and emerging trends in the treatment of Sjogren's syndrome: A bibliometric analysis from 1900 to 2022

OBJECTIVE

Sjogren's syndrome (SS) is an autoimmune disease that mainly affects the salivary and lacrimal glands and further leads to dry mouth and eyes. In recent years, knowledge about the treatment of SS is developing rapidly. This study aims to assess research progress on SS treatment using a bibliometric approach and to identify research hotspots and emerging trends in this area.

METHODS

The publications related to the treatment of SS were retrieved from the Science Citation Index Expanded (SCI-E) database. The following search terms were used to extract document data: TS=(Sjogren* OR Sicca*) AND TS= (Treat* OR Therap* OR Disease Management). Articles and review articles published in English from 1900 to 2022 were selected. After the manual screening, the publication data were exported to a plain text file and applied for cooperative network analysis, keyword analysis, and reference co-citation analysis by using CiteSpace.

RESULTS

A total of 2038 publications were included in the analysis from 571 journals by 9063 authors. The annual number of published studies and times cited showed an overall upward trend since 1992. There was a degree of national/regional collaboration in this area, but direct collaboration between institutions and authors was still lacking. The country with the highest number of publications was in the United States, followed by China and Japan. Five SS-related treatments as the research hotspots were summarized by analyzing keywords and references, including immunosuppressive and anti-inflammatory therapy, regenerative therapy, gene therapy, surgical treatment, and symptomatic treatment. Among them, B cells, T cells, mucosal-associated invariant T (MAIT) cells, mesenchymal stem cells (MSCs), rituximab, belimumab, cell-target therapy, and immunosuppressive and anti-inflammatory therapy were emerging trends in this field.

CONCLUSIONS

This study conducted a data-based and objective introduction to the treatment of SS from a fresh perspective. An analysis of the intellectual bases, research hotspots, and emerging trends in the field will contribute to future research and treatment decisions, which will ultimately benefit SS patients.

A bibliometric analysis of idiopathic inflammatory myopathies from 1982 to 2021

OBJECTIVE

There has been an increasing number of literature related to idiopathic inflammatory myopathies (IIM) in the past few decades. However, there is a lack of intuitive and systematic analysis of research on IIM. Therefore, this study aimed to perform a bibliometric analysis to identify the current trends and hotspots of research on IIM.

METHODS

Articles and reviews on IIM published during 1982-2021 were acquired from the Web of Science Core Collection (WoSCC) database. VOSviewer application was applied to conduct a network analysis of the keywords, institutions, and countries. The top 100 most-cited publications regarding IIM were analyzed.

RESULTS

In total, 665 publications were included. Globally, the USA produced the most articles on IIM (144). Karolinska Institutet was the institution with the most outputs (47). Rheumatology ranked on top of journals, with 47 IIM-related documents collecting a total of 1420 citations. In the area of IIM documents, biomarkers were the most common research theme. According to the co-occurrence analysis of keywords, "cardiac involvement," "criteria," and "refractory adult" were identified as significant future research centers.

CONCLUSION

The scientific literature on IIM has advanced rapidly in the past 4 decades. The classification criteria, treatment, and extramuscular manifestations of IIM have been identified as promising research frontiers in the field. The global status and trends of the IIM literature from a bibliometric aspect can offer a helpful guidance and new insight for researchers and medical workers in the domain. Key Points • This study reveals the topic trends and knowledge structure of idiopathic inflammatory myopathies literature over the last 40 years. • This study identifies potential future research hotspots, including "cardiac involvement," "criteria," and "refractory adult."

Research trends and frontiers on antiphospholipid syndrome: A 10-year bibliometric analysis (2012-2021)

Objectives: A growing body of studies related to antiphospholipid syndrome (APS) have been published in recent years. Nevertheless, there is a lack of visualized and systematic analysis in the literature on APS. Hence, this study sought to conduct a bibliometric analysis to identify research status and discover frontiers in the field. Methods: Articles and reviews concerning APS were acquired from the Web of Science Core Collection (WoSCC) database. CiteSpace, VOSviewer and a bibliometric online analysis platform were employed to conduct a visualization and knowledge-map analysis. Results: A total of 1,390 publications regarding APS were identified. Globally, Italy contributed the most publications. The University of Padua was the most productive institution. Lupus ranked first in both the most published and most co-cited journals. Savino Sciascia and Spiros Miyakis were the most prolific and most co-cited authors, respectively. "Vitamin K antagonists (VKA)" and "immunoglobulin A (IgA)" were current research foci. Burst analysis of keywords suggested that "neutrophil extracellular trap (NET)," "direct oral anticoagulant (DOAC)," "open label," "outcome," "hydroxychloroquine (HCQ)," and "arterial thrombosis (AT)" were significant future research frontiers. Conclusion: The scientific literature on APS has increased steadily in the past 10 years. The clinical studies on the treatment and mechanism research of APS are recognized as promising research hotspots in the domain of APS. The research status and trends of APS publications from the bibliometric perspective can provide a practical guide and important reference for subsequent studies by researchers and physicians in the domain.
