Helicobacter Pylori Eradication in Diabetic Subjects With Non-alcoholic Fatty Liver Disease

The Effect of Helicobacter Pylori Eradication on Liver Fat Content in Diabetic Subjects With Non-alcoholic Fatty Liver Disease

The aim of study was to evaluate the effect of helicobacter pylori eradication on liver fat content, liver function tests, lipid profile, homeostasis model assessment-IR (HOMA-IR) index, and anthropometric measurements (body mass index and waist circumference)in diabetic subjects with non-alcoholic fatty liver disease.

Study Overview

• Status: Completed
• Conditions: Non-alcoholic Fatty Liver Disease
• Intervention / Treatment: Drug: H.pylori eradication

Detailed Description

Helicobacter pylori (HP) antigens have been found in the liver of individuals with benign and malignant liver diseases. The role of HP in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) is controversial.

This randomized double blind clinical trial was performed in diabetic dyspeptic patients with positive antibody to HP and the evidence of fatty liver in ultrasonography. After excluding other causes, participants with persistent elevated serum aminotransferase levels were presumed to have NAFLD. Those with NAFLD liver fat score greater than (-0.64) and positive urea breath test (UBT) were enrolled. They were randomly assigned to lifestyle modification alone or lifestyle modification plus HP eradication groups. Quadruple therapy (omeprazole, amoxicillin, bismuth subcitrate, and clarithromycin) for HP eradication was performed in two weeks. HP eradication was documented by UBT. Liver fat content, fasting serum glucose, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, triglyceride, cholesterol, high and low-density lipoprotein, HOMA-IR, and anthropometric measurements (body mass index and waist circumference) were checked at baseline and six weeks post-treatment.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Liver Fat Content Change From Baseline to Six Weeks Post H.Pylori Treatment	Liver fat content was calculated by a valid formula. The formula is as the followings:Liver fat content (%) = 10 (-0.805 + 0.282 * metabolic syndrome (yes = 11 no = 0) + 0.078 * type 2 diabetes (yes =2 / no =0) + 0.525 * log fasting serum insulin (mU/L) + 0.521 * log fasting serum AST (U/L) - 0.454 * log (AST/ALT)	baseline and 6 weeks
