Meanwhile, the pathogenesis of NAFLD needs further research, and effective treatment for this disease remains elusive. In this mini-review, we enumerate and ponder on the evidence demonstrating an association between <jats:italic>H. pylori<\/jats:italic> infection and NAFLD. Primarily, we delve into high-quality meta-analyses and clinical randomized controlled trials focusing on the association studies between the two. We also discuss clinical studies that present opposite conclusions. In addition, we propose a mechanism through which <jats:italic>H. pylori<\/jats:italic> infection aggravates NAFLD: inflammatory cytokines and adipocytokines, insulin resistance, lipid metabolism, intestinal barrier and microbiota, <jats:italic>H. pylori<\/jats:italic> outer membrane vesicles and <jats:italic>H. pylori<\/jats:italic>-infected cell-extracellular vesicles. This mini-review aims to further explore NAFLD pathogenesis and extragastric disease mechanisms caused by <jats:italic>H. pylori<\/jats:italic> infection.<\/jats:p>","DOI":"10.3389\/fcimb.2023.1282956","type":"journal-article","created":{"date-parts":[[2023,12,8]],"date-time":"2023-12-08T10:24:36Z","timestamp":1702031076000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":17,"title":["An update: is there a relationship between H. pylori infection and nonalcoholic fatty liver disease? why is this subject of interest?"],"prefix":"10.3389","volume":"13","author":[{"given":"Xingcen","family":"Chen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruyi","family":"Peng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongzi","family":"Peng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jia","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deliang","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rong","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2023,12,8]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","DOI":"10.1111\/hel.12537","article-title":"Helicobacter pylori and non-alcoholic fatty liver disease: A new enigma","volume":"23","author":"Abdel-Razik","year":"2018","journal-title":"Helicobacter"},{"key":"B2","doi-asserted-by":"publisher","first-page":"597","DOI":"10.1128\/CMR.00006-06","article-title":"Helicobacter pylori persistence: an overview of interactions between H. pylori and host immune defenses","volume":"19","author":"Algood","year":"2006","journal-title":"Clin.
