STUDY OBJECTIVES The primary endpoint was change in ALT after 6 weeks of Rifaximin. Secondary endpoints were change in hepatic lipid content and insulin sensitivity measured with a hyperinsulinaemic euglycaemic clamp.
STUDY DESIGN This was an open-label study of Rifaximin (Normix, Alfa Wasserman S.p.A, Bologna, Italy) 400mg twice daily for six weeks followed by a further six weeks observation period during which patients received standard care. Compliance with treatment was checked by collection of empty blister packs. Subjects were asked to provide a structured dietary and lifestyle history as previously described (Williams HR, Cox IJ, Walker DG, North BV, Patel VM, Marshall SE, Jewell DP, et al. Characterization of inflammatory bowel disease with urinary metabolic profiling. Am J Gastroenterol 2009;104:1435-1444). The primary endpoint was change in ALT after 6 weeks' Rifaximin therapy. Secondary endpoints were change in hepatic and whole-body insulin sensitivity assessed by the two-stage hyperinsulinaemic euglycaemic clamp and change in hepatic triglyceride content assessed by proton nuclear magnetic resonance spectroscopy at 6 weeks from baseline. Serum ALT, biochemistry and anthropometrics were also measured at 12 weeks to look for longer-term effects. Stool microbiota, urinary metabolic profile and serum cytokine profile were measured before and after intervention.
PARTICIPANT ENTRY
INCLUSION CRITERIA Male and female patients were eligible for inclusion if aged between 18 and 70 years with non-alcoholic steatohepatitis histologically-proven, as evidenced by the presence of all of: steatosis, hepatocyte ballooning and lobular inflammation, and scored according to Kleiner(18) by a single experienced histopathologist (RDG) within the previous year, with or without mild to moderate fibrosis (stage 0-3/4) and with persistently elevated alanine aminotransferase (ALT) values on at least two occasions in the three months prior to recruitment.
EXCLUSION CRITERIA Patients were excluded if there was histological evidence of cirrhosis; hepatic decompensation; regular alcohol consumption exceeding 14 units/week (16g ethanol/day) for a woman or 21 units/week (24g ethanol/day) for a man; evidence of viral, autoimmune or other metabolic liver disease on a chronic liver disease screen; a history of malignancy or systemic inflammatory conditions; myocardial infarction or cerebrovascular events in the preceding 6 months; a history of bariatric surgery, blind loop or short bowel; use of any treatment known or suspected to change bowel flora within 3 months of enrolment; initiation or major dose change of metformin, thiazolinediones, biguanides, statins, fibrates, anti-obesity medications or insulin within 3 months of enrolment.
