<i>Helicobacter pylori</i> (<i>H. pylori</i>) is one of the most common pathogens that can cause certain gastrointestinal disorders, such as gastritis, peptic ulcers, and gastric cancer. Recently, interest in the systemic effects of <i>H. pylori</i> on extragastric manifestations is increasing. Representative diseases include hematologic, cardiovascular, neurodegenerative, autoimmune, dermatologic, allergic, hepatobiliary, and metabolic diseases. Among them, since the prevalence of metabolic diseases is on the rise worldwide, the relationship between <i>H. pylori</i> infection and metabolic diseases has become an interesting research issue. Many studies have been conducted to clarify any association. However, the results of those studies still remain controversial. This review focuses on recently published studies to investigate the relationship between <i>H. pylori</i> infection and metabolic diseases, including diabetes mellitus, metabolic syndrome, obesity, and non-alcoholic fatty liver disease, and their associated pathophysiology.

Objective: To assess the association between PTGS1 and NOS3 variant alleles and the risk to develop upper gastrointestinal bleeding (UGIB) secondary to complicated peptic disease.Methods: A case–control study was conducted in a Brazilian complex hospital from July 2016 to March 2020. Case: Patients with UGIB diagnosis. Control: Patients admitted for surgery not related to gastrointestinal disorders. Variables: UGIB (outcome), genetic variants in PTGS1 and NOS3 genes (independent), and sex, age, schooling, ethnicity, previous history of gastrointestinal disorders, Helicobacter pylori serology, comorbidity, drug therapy, and lifestyle (confounding). The single-nucleotide polymorphisms (SNPs) of the PTSG1 gene (rs1330344, rs3842787, rs10306114, and rs5788) and NOS3 gene (rs2070744 and rs1799983) were determined using the real-time polymerase chain reaction. Helicobacter pylori serology was determined through the chemiluminescence technique. Logistic regression models were built and deviations of allelic frequencies from Hardy–Weinberg equilibrium were verified.Results: 200 cases and 706 controls were recruited. Carriers of the AG genotype of rs10306114 (OR: 2.55, CI 95%: 1.13–5.76) and CA + AA genotypes of rs5788 (OR: 2.53, CI 95%: 1.14–5.59) were associated with an increased risk for the UGIB development. In nonsteroidal anti-inflammatory drugs (NSAIDs) users, the six variants evaluated modified the magnitude of the risk of UGIB, whereas in low-dose aspirin (LDA) users, an increased risk of UGIB was observed for four of them (rs1330344, rs10306114, rs2070744, and rs1799983). Personal ulcer history (p-value: &lt; 0.001); Helicobacter pylori infection (p-value: &lt; 0.011); NSAIDs, LDA, and oral anticoagulant use (p-value: &lt; 0.001); and alcohol intake (p-value: &lt; 0.001) were also identified as independent risk factors for UGIB.Conclusion: This study presents two unprecedented analyses within the scope of the UGIB (rs10306114 and rs2070744), and our findings showing an increased risk of UGIB in the presence of the genetic variants rs10306114 and rs5788, regardless of the drug exposure. Besides, the presence of the evaluated variants might modify the magnitude of the risk of UGIB in LDA/NSAIDs users. Therefore, our data suggest the need for a personalized therapy and drug use monitoring in order to promote patient safety.
