Helicobacter pylori infection in patients with metabolic syndrome, with or without nonalcoholic fatty liver disease

Abstract

Abstract Background Helicobacter pylori (HP) infection is considered a risk factor of GIT diseases, e.g., gastric and duodenal ulcers and gastric carcinomas. It is transmitted through feco/oral route and can be diagnosed by many methods, e.g., stool antigen test (SAT). Metabolic syndrome (MET S) is considered a circle of metabolic derangements that can cause some complications as ischemic changes and heart diseases. Metabolic syndrome may also cause nonalcoholic fatty liver disease (NAFLD) resulting in liver fibrosis, cirrhosis, and HCC. Results The study included 300 subjects recruited from Obesity Clinic and Diabetes & Endocrinology Unit, Specialized Medical Hospital, Mansoura University. Two hundred of metabolic syndrome patients were subdivided into two groups according to the presence or absence of NAFLD, in addition to 100 subjects not having metabolic syndrome and served as control group. We found that HP infection is more frequent in MET S with NAFLD patients (73%) than in MET S without NAFLD (47%) with (P value < 0.001) emphasizing that HP infection increases the risk of NAFLD development in patients with MET S. The study proved that HP infection is associated with increased degree of fibrosis significantly (P value < 0.001) with progression to marked fibrosis which may complicate with NASH with over all predictive value of 75% especially in patients with hyperglycemia. Conclusions Our findings show that a circle of metabolic abnormalities seems to be attributed to HP infection in MET S patients increasing the risk of fatty liver and progression to marked fibrosis especially with coexistent hyperglycemia, dyslipidemia, and upper body obesity. Diagnosis and early eradication of HP infection will help in decreasing metabolic disturbances and possibility of NAFLD, and protect against marked fibrosis progression.
