Primary Outcome Measures:
  • Liver Fat Content Change From Baseline to Six Weeks Post H.Pylori Treatment [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Enrollment: 40
Study Start Date: September 2012
Study Completion Date: March 2013
Primary Completion Date: February 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Lifestyle modification
Obtaining ideal body weight by calorie restriction diet and programmed physical activity
Experimental: H.pylori eradication
H.pylori eradication by quadruple antibiotic therapy for two weeks plus obtaining ideal body weight by calorie restriction diet and programmed physical activity
Drug: H.pylori eradication
The regimen consists of Omeprazole (20 mg/BD)+ Amoxicillin (1 g/day)+ Bismuth subcitrate (240 mg/BD)+ Azithromycin (500 mg/BD)for two weeks
Other Name: Helicobacter pylori treatment

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.
