Non alcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease, it encompasses from simple steatosis to non alcoholic steatohepatitis (NASH) and, eventually leads to cirrhosis and hepatocellular carcinoma (HCC). Dysbiosis, over nutrition, life style, type 2 diabetes (T2DM) and metabolic syndrome are main causes in the disease progression. Research on the role of gut-liver axis in the pathogenesis of NAFLD has been slowly accumulating over the past few years. Endotoxemia resulting from intestinal bacterial overgrowth may contribute to the pathogenesis of NAFLD. So, intestinal microbiota (IM) serve as a potential therapeutic target in NASH. In this regard, we have aimed to test the efficacy of rifaximin against simple steatosis (NAFLD) and steatohepatitis (NASH) subjects in relation to serum endotoxins and related pro-inflammatory cytokine levels. We hypothesis that Rifaximin treatment may influence the endotoxin levels by modulating gut microbiota and partial alleviate from NAFLD/NASH.

Primary Outcome Measures:
  • Drop in the levels of pro-inflammatory cytokines and increase in anti-inflammatory cytokines [ Time Frame: 1 month ]
    Rifaximin treatment to both patient groups at the dose of 1200 mg/daily for 28 days. Blood samples obtain from all patients at 0 day, 14th day, 28th day and 60th day and collect serum for the analysis of the endotoxins and pro-inflammatory cytokines -TLR-4, TNF-α, IL-1 α, IL-6, IL-10 & IL-12 levels.

Detailed Description:

Study area:

This prospective study conducted from July 2013 to March 2014 at Bezmialem Vakif University School of Medicine in the Department of Gastroenterology.

Subjects and methods:

Patients between the ages of 18-70, irrespective of gender referred to the gastroenterology clinics for persistently elevated liver enzymes, obesity, type 2 diabetes mellitus (T2DM) and clinical suspicion of NAFLD selected for this study. During the initial visit, patients are invited to participate in this study. After providing written informed consent, these patients received a detailed medical history, physical examination, Age, sex, BMI, waist circumference and appropriate laboratory tests will be made. Ultrasonography (US) examination takes place before biopsy.

Endotoxins and Pro-Inflammatory cytokine assays:

These assays are going to perform by using following ELISA kits. Tumour necrosis factor (TNF)-α, interleukin (IL)-1, IL-6, IL-10 and IL-12 obtained from EBIOSCİENCE company. LAL chromogenic end point assay kit obtained from HYCULT company and toll like receptor (TLR)-4 assay kit obtained from USCN company.

Statistical Analysis:

Statistical calculations 'Statistical Package for Social Sciences' (SPSS) software package for Windows 16 computer program was used. Descriptive statistics when numeric data as mean ± standard deviation, proportional data were used as the number and percentage rates. Independent samples t-test to compare the groups, and the chi-square and Mann-Whitney U tests were used for statistical analysis. P <0.05 will be considered as the limit of statistical significance.
