Helicobacter Pylori Eradication in Non-diabetic Non-alcoholic Steatohepatitis

Phase 2

Completed

Brief Summary: 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 non-diabetic subjects with non-alcoholic fatty liver disease.

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 non-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.

Recruitment & Eligibility

Inclusion Criteria

Dyspeptic patients with positive antibody to H.pylori and persistent elevated aminotransferase levels with the evidence of fatty liver in ultrasonography, who were referred to a gastroenterology clinic.

Exclusion Criteria

Alcohol use (more than 20 gram per day in men and 10 gram per day in women per day), diabetes mellitus, heart disease (ischemic or congestive), hepatic disease (viral hepatitis, autoimmune hepatitis, wilson disease, hemochromatosis, liver mass lesion), renal disease (serum creatinine concentration of > 1.5 mg/dl), any severe systemic co-morbidities, neoplasm, using any medication during the past 3 months, previous history of peptic ulcer, previous history of H.pylori eradication, existence of alarm signs (weight loss, dysphagia, anemia, vomiting, positive family history of gastrointestinal cancers), and pregnant or lactating women.

Arm && Interventions

Group	Intervention	Description
H.pylori eradication	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

Primary Outcome Measures

Name	Time	Method
Liver Fat Content	8 weeks (6 weeks post-treatment)	Primary outcome measure was changes in the liver fat content from baseline to the end of study (6 weeks post-treatment). The percent of liver fat was calculated as below: "Liver fat content (%) = 10 (-0.805 + 0.282 \* metabolic syndrome (yes = 1 / 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)"

Secondary Outcome Measures

Name	Time	Method
Serum Alanine Aminotransferase Level	8 weeks	Secondary outcome measure was change in serum alanine aminotransferase concentration from baseline to the end of study
Serum Aspartate Aminotransferase Level	8 weeks	Secondary outcome measure was change in serum aspartate aminotransferase concentration from baseline to the end of study
Anthropometric Measurements	8 weeks	Secondary outcome measure was change in anthropometric measurements (body mass index and waist circumference) from baseline to the end of study
Serum Lipid Profile	8 weeks	Secondary outcome measure was change in serum lipid profile (including serum triglyceride, cholesterol, low-density lipoprotein, and high-density lipoprotein concentration) from baseline to the end of study
Fasting Serum Glucose	8 weeks	Secondary outcome measure was change in fasting serum glucose concentration from baseline to the end of study
Homeostasis Model Assessment-Insulin Resistance (HOMA-IR)	8 weeks	Secondary outcome measure was change in HOMA-IR from baseline to the end of study
