Bibliometric analysis of Helicobacter pylori resistance-from 2002 to 2022

Drug resistance in Helicobacter pylori severely affects the efficacy of eradication therapy, and a number of studies have been conducted on this issue. The aim of this study was to assess the progress in this field using a bibliometric approach.

Publications related to H. pylori resistance from 2002 to 2022 were retrieved from the Web of Science database. Relevant information including titles, authors, countries, and keywords was extracted, and the data were processed using Excel, VOSviewer, and CiteSpace software for co-authorship, co-citation, and co-occurrence analysis.

From 2002 to 2022 (as of 09/24/2022), the field of H. pylori-resistance research produced a total of 2677 publications with a total of 75217 citations, with an overall upward trend in the annual number of articles published, reaching a peak of 204 in 2019. Articles were mainly published in Q1 or Q2 journals, with Helicobacter (TP = 261) publishing the most literature, Baylor College of Medicine (TP = 68) and Deng-chyang wu (TP = 38) being the most prolific institutions and authors, respectively. China and the United States were the locations of most of the articles, accounting for 35.08% of the global publication volume. Keyword co-occurrence analysis divided H. pylori-resistance research into four clusters: "Therapeutic Strategies," "Diseases," "Mechanism Research and Epidemiology," and "Drug Research." "Drug research" and burst detection indicate that the current research hotspot involves the selection and analysis of treatment strategies.

H. pylori-resistance research has become a popular research field, and although there are significant contributions from Europe, the United States, and East Asia, there are significant imbalances between regions that cannot be ignored. In addition, the exploration of treatment strategies remains a key issue for research at the current stage.
