Helicobacter pylori infection may increase the severity of nonalcoholic fatty liver disease via promoting liver function damage, glycometabolism, lipid metabolism, inflammatory reaction and metabolic syndrome

Background and aim Recent clinical trials have confirmed that Helicobacter pylori infection is positively associated with nonalcoholic fatty liver disease (NAFLD), although some research has shown a negative association. Therefore, to confirm whether H. pylori eradication treatment is feasible for NAFLD patients in our hospital, we aimed to establish the association between H. pylori infection and NAFLD. Methods We enrolled 91 patients with NAFLD diagnosed by abdominal B-mode ultrasonography between January and December 2018. H. pylori infection was confirmed by C13 urea breath test, and liver function, glycometabolism, insulin sensitivity, lipid metabolism, as well as inflammatory reaction were assessed through blood biochemical analyses. Results A minority of NAFLD patients had liver dysfunction, increased fasting glucose and insulin levels, a score of insulin-resistance (HOMA-Ir), lipid metabolism, slight inflammatory response, fasting hyperglycemia and hypertension. Most patients were complicated with overweight/visceral obesity and dyslipidemia. Moreover, these abnormal indicators were closely associated with the severity of NAFLD and H. pylori infection. Notably, the prevalence of H. pylori infection showed a significant difference between mild, moderate and severe NAFLD, and hepatic steatosis with coexistent NAFLD also revealed a striking difference between H. pylori-positive and H. pylori-negative patients (P
