Intestinal Microbiota Transplantation for Nonalcoholic Fatty Liver Disease

Not Applicable

• Conditions: Non-alcoholic Fatty Liver Disease
• Interventions: Other: intestinal microbiota transplantation

• Registration Number: NCT03648086
• Lead Sponsor: Zhongshan Hospital Xiamen University

Brief Summary

In China, with the improvement of living standards, there is a significant increase in the rate of prevalence of type 2 diabetes and hyperlipidemia, associated with Non-alcoholic fatty liver disease（NAFLD） which has gradually become a major public health problem in our country. The latest study found that intestinal microflora imbalance is closely correlated with NAFLD. In this subject, the investigators aim to explore whether intestinal microbiota transplantation(IMT) could reverse the change of intestinal microflora imbalance and has direct effects of NAFLD.

Detailed Description

Non-alcoholic fatty liver disease (NAFLD) is a significant health problem. With the trend of obesity and associated metabolic syndrome globally, nonalcoholic fatty liver disease has become a high incidence of liver disease in developed countries, the prevalence rate of NAFLD adult is about 10% \~ 30%. Therefore, effective prevention and treatment of NAFLD has important significance in improving people's quality of life and disease prognosis. The latest study found that intestinal microflora imbalance is closely correlated with NAFLD. When the structure of intestinal flora is destroyed, host energy absorption and storage of fat balance will be broken, with higher absorption of efficiency. At the same time, metabolic disorder expands. In this projects the investigators aim to re-establish a gut balance of intestinal microbiota through Standardized Intestinal Microbiota Transplantation for NAFLD. The CT ratio of liver/spleen, Fibroscan E value, general indicators, biochemical indicators will be used to assess the efficiency, durability and safety of Standardized IMT at the start and end of the projects.

Arm && Interventions

Group	Intervention	Description
IMT	intestinal microbiota transplantation	30 non-alcoholic fatty liver disease（NAFLD） patients will be recruited for the study, which involved a 6 times intestinal microbiota transplant(IMT) and the time interval is generally 2 weeks.

Primary Outcome Measures

Name	Time	Method
The change of CT ratio of liver/spleen	3 months, 6months	CT imaging has been used to assess hepatic steatosis and has been validated in relation to liver biopsy .The ratio of liver to spleen (L/S ratio) for CT attenuation values is an index, with a L/S ratio\<1 considered to represent fatty liver .The change of CT ratio of liver/spleen will be assessed at different time comparing with the baseline.

Secondary Outcome Measures

Name	Time	Method
biochemical indicators	3 months, 6months	Liver function such as ALT,AST,ALT/AST will be assessed at different time comparing with the baseline.
Fibroscan E value	3 months, 6 months	Fibroscan E value is a indicators for evaluating liver fibrosis.Changes will be assessed at different time comparing with the baseline.
Changes of gut microbiota	3 months, 6months	Alpha and Beta diversity of GI microbiota by High-throughput sequencing on baseline line and 3 months, 6months after treatment
