Study on Effect of Intestinal Microbiota Transplantation in Chronic Hepatitis B

Not Applicable

• Conditions: Chronic Hepatitis b
• Interventions: Other: intestinal microbiota transplant; Drug: Antiviral Agents

• Registration Number: NCT03429439
• Lead Sponsor: Zhongshan Hospital Xiamen University

Brief Summary

Chronic hepatitis B(CHB) is a common infectious disease affecting up to 2 billion people worldwide. Around 650 thousand people died of liver failure, cirrhosis and primary liver cancer caused by chronic hepatitis B every year. Age is the main factor affecting the chronicity of hepatitis B, while 90% and 25% to 30% of hepatitis b virus(HBV) infection in perinatal and infant period will develop into chronic infection respectively. Whereas the proportion in patients above 5 years old is only 5% to 10%. Intestinal microbiota plays an important role in maintaining normal physiological function of the intestine and the immune function of the body. It has been found that the disorder of intestinal microbiota is associated with numerous intestinal and parenteral diseases. Intestinal microbiota transplantation(IMT) is a significant method to reconstruct intestinal flora. Recently, the relationship between immune response and intestinal microbiota has been claimed. In a previous study using IMT to treat HBeAg positive chronic hepatitis B patients combined with antiviral therapy, 80% of them has reached HBeAg clearance. The investigators propose a randomised trial of IMT in patients with chronic hepatitis B combined with antiviral therapy. The investigators will assess the serum HBsAg, anti-HBs, HBeAg, anti-HBe, anti-hepatitis B core antigen, the relief of gastrointestinal symptoms, and the fecal microbiota before and after IMT. Patients will be randomized to either antiviral therapy or IMT combined antiviral therapy over a 26 weeks period.

Detailed Description

A group of 60 chronic hepatitis B patients combined with antiviral therapy will be recruited for study, which involved a 6 times IMT with gastroduodenoscopy and the time interval is generally 2 weeks. All participants will keep their present antiviral therapy. All participants will be assessed at baseline, after 1 months, 3 months, 6 months from baseline in order to evaluate the possible changes in:(1)Decrease of serum hepatitis B virus surface antigen(HBsAg) levels(as measured in IU/mL) and hepatitis B virus e antigen(HBeAg) levels(as measured in S/CO); (2)Appearance of serum anti-hepatitis B virus surface antigen(anti-HBs) and anti-hepatitis B virus e antigen(anti-HBe); (3)Relief of gastrointestinal symptoms:The onset and duration of gastrointestinal symptoms will be assessed by "Evaluation Score Table of Gastrointestinal Symptoms"; (4)Changes of gut microbiota: The changes of gut microbiota will be assessed by High-throughput sequencing (16S rRNA) in fecal samples from recruited patients before and after IMT.
