RESUMO
OBJECTIVE: To evaluate the Peruvian scientific production on Helicobacter pylori. MATERIALS AND METHODS: Bibliometric analysis of original articles published until September 8, 2020, in journals indexed in PubMed, Scopus, Web of Science, LILACS, and SciELO. Bibliometric indicators were obtained. Likewise, analysis of the co-citation of authors and co-occurrence of terms with the terms included in the title and the abstract of publications was performed. RESULTS: Data from 180 original articles were analyzed. An increase in the number of articles on H. pylori was found (R2 = 0.64, an average annual growth rate of 8.01%). A total of 777 authors were identified, with an average number of articles per author of 0.18, and a collaboration index of 5.64. The average number of citations per original article was 1.91. The Universidad Peruana Cayetano Heredia was the institution with the highest number of original articles (63.2%). The analysis of co-occurrence of terms found terms related to gastric cancer during the whole study period and, for recent years, terms related to the treatment of H. pylori infection and water sources. CONCLUSION: There is an increase in Peruvian production in original articles on H. pylori. In recent years, the study of the eradication of H. pylori and the transmission of the agent from water sources have been topics of interest.

RESUMEN Objetivo : Evaluar la producción científica peruana sobre Helicobacter pylori. Materiales y métodos : Análisis bibliométrico de artículos originales publicados hasta el 8 de setiembre de 2020 en revistas indexadas en PubMed, Scopus, Web of Science, LILACS y SciELO. Se obtuvieron indicadores bibliométricos. Asimismo, se realizó un análisis de la co-citación de autores y co- ocurrencia de términos con los términos incluidos en el título y el resumen de las publicaciones. Resultados : Se analizaron datos de 180 artículos originales. Se encontró un aumento en el número de artículos sobre H. pylori (R2 = 0,64, una tasa de crecimiento anual promedio de 8,01%). Se identificaron un total de 777 autores, con una media de artículos por autor de 0,18 y un índice de colaboración de 5,64. El número medio de citas por artículo original fue de 1,91. La Universidad Peruana Cayetano Heredia fue la institución con mayor número de artículos originales (63,2%). El análisis de co-ocurrencia de términos encontró términos relacionados con el cáncer gástrico durante todo el período de estudio y, en los últimos años, términos relacionados con el tratamiento de la infección por H. pylori y fuentes de agua. Conclusión : Existe un aumento en la producción peruana de artículos originales sobre H. pylori. En los últimos años, el estudio de la erradicación de H. pylori y la transmisión del agente desde fuentes de agua han sido temas de interés.
