To Evaluate the Beneficial Effect of Probiotics on NAFLD Patients and the Role of Gut Microbiota Modulation

To Evaluate the Clinical Efficacy of Probiotic in Patients With NAFLD

In this study, the improvement of the clinical status of early-stage non-alcoholic fatty liver disease (NAFLD) patients after the probiotic intervention will be assessed. And the mechanism of probiotics to prevent the progression of illness would be investigated. The chronic inflammation status, systemic oxidative stress, metabolism of carbohydrates and lipid, and gut microbiota of NAFLD patients will also be analyzed.

Uncontrolled NAFLD evolves in Non-Alcoholic SteatoHepatitis (NASH), cirrhosis and liver cancer. Early intervention to prevent the progression of illness of NAFLD is very important. From 2005 to 2018, 15 clinical trials concluded that multiple-strain probiotics significantly reduced the liver inflammation index and blood lipids in NAFLD patients. Many reports indicated that NAFLD-associated risk factors, such as chronic inflammation, oxidative stress, insulin resistance, dyslipidemia, and obesity are closely correlated with gut microbiota. Some substances (such as endotoxin and alcohol) produced by harmful gut bacteria caused the progression of the illness of NAFLD.

Three strains are Genmont® Normal Lactobacillus (GMNL) which were divided from natural environments, included Lactobacillus reuteri GMNL-263 (heat-killed) and GMNL-89 (alive) and Lactobacillus rhamnosus GMNL-74 ( alive). They are all isolated from the gastrointestinal tract of healthy Taiwanese and were known as common food material worldwide. The previous clinical research on probiotic consumption in type 2 Diabetes mellitus patients under normal drug treatment was conducted in Changhua Christian Hospital. Results showed that L. reuteri GMNL-263 was able to stabilize the weight and blood pressure of patients. L. reuteri GMNL-89 had a stable effect on glycated hemoglobin. There was no adverse reaction when probiotics combining with type 2 diabetes drugs. Meanwhile, L. rhamnosus GMNL-74 was observed to reduce weight gain in obese mice. In this clinical study, The anti-liver inflammation effect of consumption of Lactobacillus sachet in NAFLD patients will be demonstrated at baseline, 3 months and 6 months. In this clinical study, the anti-liver inflammation effect of consumption of Lactobacillus sachet in NAFLD patients will be demonstrated at baseline, 3 months and 6 months to understand the impact of the probiotics on NAFLD. Since the treatment of fatty liver should focus on controlling weight, blood sugar, and blood fat, the relevant clinical indexes will also be investigated.
