CHB: Study on Effect of Intestinal Microbiota Transplantation in Chronic Hepatitis B
Study Details
Study Description
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.

Outcome Measures
Primary Outcome Measures
- Change of serum hepatitis B virus e antigen(HBeAg) level [1 month, 3 months, 6months]
Serum hepatitis B virus e antigen(HBeAg) levels is measured in S/CO
Secondary Outcome Measures
- Change of serum hepatitis B virus surface antigen(HBsAg) level [1 month, 3 months, 6months]
Serum hepatitis B virus surface antigen(HBsAg) levels is measured in IU/mL .
- Change of serum anti-hepatitis B virus e antigen(anti-HBe) [1 month, 3 months, 6months]
Appearance of serum anti-hepatitis B virus e antigen(anti-HBe) suggest the ability of body to resistant HBV.
- Change of serum anti-hepatitis B virus surface antigen(anti-HBs) [1 month, 3 months, 6months]
Appearance of serum anti-hepatitis B virus surface antigen(anti-HBs) suggest the ability of body to resistant HBV.
- Changes of gut microbiota [1 month, 3 months, 6months]
Alpha and Beta diversity of GI microbiota by High-throughput sequencing (16S rRNA) on baseline line and1 month, 3 months, 6months after treatment
- relief of constipation [1 month, 3 months, 6months]
The onset and duration of constipation will be assessed by "Evaluation Score Table of Gastrointestinal Symptoms".
- relief of diarrhea [1 month, 3 months, 6months]
The onset and duration of diarrhea will be assessed by "Evaluation Score Table of Gastrointestinal Symptoms".
- relief of abdominal pain [1 month, 3 months, 6months]
The onset and duration of abdominal pain will be assessed by "Evaluation Score Table of Gastrointestinal Symptoms".
