Study Summary

Nonalcoholic fatty liver disease (NAFLD) is a disease of alarmingly increasing prevalence, linked to metabolic, cardiovascular and malignant morbidity and without any officially approved treatment. It is increasingly recognized that the gut microbiome is implicated in the pathogenesis and progression of numerous chronic diseases, including NAFLD. Through the so-called gut-liver axis, the liver is exposed to gut-bacterial-derived products, including toxins (lipopolysaccharides), enzymes (methylamines), alcohol, and short-chain fatty acids (mainly acetate, propionate, and butyrate), that may lead to accumulation of triglycerides, inflammatory responses, oxidative stress and accompanying damage to the hepatocytes. The primary objective is to study the effect of consecutive FMT on liver fat accumulation measured by Magnetic Resonance Images (MRI) LiverMultiscan at 12 weeks. Secondary objectives are weight, waist, blood pressure, metabolic parameters (including glucose, cholesterol, pancreatic beta-cell function, HOMA-IR), objective and subjective stress indicators, gut-microbiota and bile composition and liver enzymes. Stool samples will be collected for microbiota analysis at time point 0, 3, 6 and 12 weeks.

Study Description

Nonalcoholic fatty liver disease (NAFLD) is a disease of alarmingly increasing prevalence, linked to metabolic, cardiovascular and malignant morbidity and without any officially approved treatment. It is increasingly recognized that the gut microbiome is implicated in the pathogenesis and progression of numerous chronic diseases, including NAFLD. Through the so-called gut-liver axis, the liver is exposed to gut-bacterial-derived products, including toxins (lipopolysaccharides), enzymes (methylamines), alcohol, and short-chain fatty acids (mainly acetate, propionate, and butyrate), that may lead to accumulation of triglycerides, inflammatory responses, oxidative stress and accompanying damage to the hepatocytes. The investigators hypothesize that altered gut microbiota underlie (hepatic) insulin resistance and liver fat accumulation in NAFLD patients. Fecal microbiota transplantation, through amelioration of gut-microbiota released products like lipopolysaccharides, short-chain fatty acids, alcohol and enzymes, and changes in bile acids, may positively affect NAFLD.

During the study 20 patients will be randomized for infusion of allogenic (lean donor) or autologous (own) feces by gastroscopy at time points 0, 3 and 6 weeks on a 1:1 basis. Prior to randomization, and at 12 weeks, all patients will undergo LiverMultiscan to non-invasively quantify liver fat accumulation and other features of NAFLD. In addition, various metabolic parameters (lipids, HOMA-IR), objective and subjective stress indicators, gut-microbiota and bile composition, and liver enzymes will be measured.

The primary objective is to study the effect on consecutive FMT on liver fat accumulation measured by Magnetic Resonance Images (MRI) LiverMultiscan at 12 weeks. Secondary objectives are alterations in anthropometrical data (weight, waist, blood pressure), changes in fecal microbiota, liver enzymes, bile composition and metabolic parameters including glucose, lipids, pancreatic beta-cell function and insulin resistance measured as HOMA-IR and objective and subjective stress indicators.
