Vonoprazan and amoxicillin dual therapy as the first-line treatment of Helicobacter pylori infection: A systematic review and meta-analysis.

BACKGROUND: Recent clinical trials have evaluated the efficacy of vonoprazan-amoxicillin (VA) dual therapy as the first-line treatment for Helicobacter pylori infection in different regions with inconsistent results reported. In this systematic review and meta-analysis, we aimed to evaluate the efficacy of VA dual therapy compared to the currently recommended therapy for eradicating H. pylori. MATERIALS AND METHODS: A comprehensive search of the PubMed, Cochrane, and Embase databases was performed using the following search terms: ("Helicobacter" OR "H. pylori" OR "Hp") AND ("vonoprazan" OR "potassium-competitive acid blocker" OR "P-CAB") AND ("amoxicillin" OR "penicillin") AND ("dual"). The primary outcome was to evaluate the eradication rate according to intention-to-treat and per-protocol analysis. The secondary outcomes were adverse events and compliance. RESULTS: A total of 15 studies involving 4, 568 patients were included. The pooled eradication rate of VA dual therapy was 85.0% and 90.0% by intention-to-treat and per-protocol analysis, respectively. The adverse events rate and compliance of VA dual therapy were 17.5% and 96%, respectively. The efficacy of VA dual therapy was superior to proton pump inhibitors-based triple therapy (82.0% vs. 71.4%, p < 0.01) but lower than vonoprazan-containing quadruple therapy (83.1% vs. 93.3%, p = 0.02). 7-day VA dual therapy showed lower eradication rates than 10-day (χ2 = 24.09, p < 0.01) and 14-day VA dual therapy (χ2 = 11.87, p < 0.01). The adverse events rate of VA dual therapy was lower than vonoprazan triple therapy (24.6% vs. 30.9%, p = 0.01) and bismuth-containing quadruple therapy (20.5% vs. 47.9%, p < 0.01). No significant difference of compliance was observed between VA dual therapy and each subgroup. CONCLUSION: VA dual therapy, a novel regimen, showed high efficacy as the first-line treatment for H. pylori eradication, which should be optimized before application in different regions.

TikTok and Bilibili as sources of information on Helicobacter pylori in China: A content and quality analysis.

BACKGROUND: Helicobacter pylori (H. pylori) is closely associated with gastric diseases and has a high prevalence in China. Public platforms are considered common and important tools to publicize H. pylori-related information. This study aimed to assess and compare the content and quality of H. pylori-related videos on TikTok and Bilibili. MATERIALS AND METHODS: A search was performed on the TikTok and Bilibili platforms using the keyword "H. pylori". The source of upload was categorized as for-profit organizations, general users, health professionals, news agencies, nonprofit organizations, and science communicators. The Journal of American Medical Association (JAMA), Global Quality Scale (GQS), and modified DISCERN scores were used to evaluate the quality of the included videos. RESULTS: A total of 93 TikTok videos and 79 Bilibili videos were included and analyzed. TikTok videos had a significantly shorter duration than Bilibili videos (64 vs. 149 s, respectively; p < 0.001). The duration of the video showed a positive correlation with the modified DISCERN and GQS scores (p < 0.001, r = 0.388 and r = 0.437, respectively). The JAMA and modified DISCERN scores of the TikTok video were significantly higher in health professionals and nonprofit organizations than in other sources (p < 0.05). For Bilibili, science communicators had a significantly higher JAMA score than the other video sources (p < 0.001). The videos uploaded by news agencies received more views, comments, shares, and favorites than any other organization or individual (p < 0.001). CONCLUSIONS: In China, H. pylori-related videos from TikTok and Bilibili tended to provide the information regarding the transmission and eradication of H. pylori. However, many videos scored an average rating in content and quality and need to be improved. We recommend that the public obtain H. pylori-related information through videos uploaded by health professionals, nonprofit organizations, and science communicators.

Research trends on vonoprazan-based therapy for Helicobacter pylori eradication: A bibliometric analysis from 2015 to 2023.

BACKGROUND: Vonoprazan is an emerging option for the treatment of Helicobacter pylori infection. We aimed to assess the research trends and hotspots of vonoprazan-based therapy for H. pylori eradication through bibliometric analysis. MATERIALS AND METHODS: Vonoprazan-based studies for eradicating H. pylori published from 2015 to 2023 were extracted from the Web of Science using a combination of the search terms "H. pylori" and "vonoprazan." Each study was weighted according to the number of included patients. RESULTS: A total of 65 studies were included. Japan was the most productive and cooperative country, accounting for 69.2% of publications. Vonoprazan in combination with amoxicillin and clarithromycin (41.8%) was most used for eradicating H. pylori, followed by vonoprazan in combination with amoxicillin (20.4%) and vonoprazan in combination with amoxicillin and metronidazole (19.4%). The eradication rates for first-line vonoprazan-based therapies by intention to treat were: dual therapy (82.9%, 95% CI: 77.7%-88.0%), triple (83.3%, 95% CI: 79.7%-86.8%) and quadruple therapy (91.5%, 95% CI: 85.5%-97.4%), and per protocol: dual therapy (86.1%, 95% CI: 81.5%-90.7%), triple (89.3%, 95% CI: 87.9%-90.6%) and quadruple therapy (94.0%, 95% CI: 88.6%-99.4%). Vonoprazan was superior to proton pump inhibitors in triple therapy regarding empirical therapy (RR = 1.18, 95% CI, 1.14-1.22, p < 0.01) and clarithromycin-resistant group (RR = 1.71, 95% CI, 1.33-2.20, p < 0.01), but there is no significant difference between triple therapy and dual therapy (RR = 1.02, 95% CI, 0.98-1.07, p = 0.33). CONCLUSIONS: Vonoprazan has been widely used for H. pylori eradication. Further studies are needed to optimize the best duration and dosage of vonoprazan-based regimens in different regions.

Research trends on artificial intelligence and endoscopy in digestive diseases: A bibliometric analysis from 1990 to 2022.

BACKGROUND: Recently, artificial intelligence (AI) has been widely used in gastrointestinal endoscopy examinations. AIM: To comprehensively evaluate the application of AI-assisted endoscopy in detecting different digestive diseases using bibliometric analysis. METHODS: Relevant publications from the Web of Science published from 1990 to 2022 were extracted using a combination of the search terms "AI" and "endoscopy". The following information was recorded from the included publications: Title, author, institution, country, endoscopy type, disease type, performance of AI, publication, citation, journal and H-index. RESULTS: A total of 446 studies were included. The number of articles reached its peak in 2021, and the annual citation numbers increased after 2006. China, the United States and Japan were dominant countries in this field, accounting for 28.7%, 16.8%, and 15.7% of publications, respectively. The Tada Tomohiro Institute of Gastroenterology and Proctology was the most influential institution. "Cancer" and "polyps" were the hotspots in this field. Colorectal polyps were the most concerning and researched disease, followed by gastric cancer and gastrointestinal bleeding. Conventional endoscopy was the most common type of examination. The accuracy of AI in detecting Barrett's esophagus, colorectal polyps and gastric cancer from 2018 to 2022 is 87.6%, 93.7% and 88.3%, respectively. The detection rates of adenoma and gastrointestinal bleeding from 2018 to 2022 are 31.3% and 96.2%, respectively. CONCLUSION: AI could improve the detection rate of digestive tract diseases and a convolutional neural network-based diagnosis program for endoscopic images shows promising results.
