Brief Summary:
The majority of childbearing age women with hepatitis B virus infection were still in the immune tolerance period. Our recent research had shown that most puerperae after delivery had elevated ALT level. However, there is no withdrawal time recommendations after childbirth at present.Through the study of hepatitis occurrence after delivery and drug withdrawal, the investigators explore the withdrawal time of antiviral treatment during pregnancy.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis B Drug: Tenofovir Disoproxil Fumarate Not Applicable

Detailed Description:
Most of childbearing age women with hepatitis B virus infection were still in the immune tolerance period. Our recent research had shown that most puerperae after delivery had elevated ALT level, and 11.5% of patients with HBV DNA positive would lead to deterioration of liver function. Meanwhile, the highest peak of ALT level could occur in 2 weeks after delivery, then it would dropped to a low point in 4-5 weeks. However, there is no withdrawal time recommendations after childbirth at present.The aim of our study is to investigate the changes of serological indexes, the changing rule of the liver function, hepatitis status, and its correlation with antiviral therapy in pregnant women with HBV infection after delivery, and then explore the withdrawal time of antiviral treatment during pregnancy.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 560 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: The Incidence of Postpartum Hepatitis in Pregnant Women With High HBVDNA Loads
Study Start Date : January 1, 2017
Estimated Primary Completion Date : December 30, 2019
Estimated Study Completion Date : December 30, 2019


Arm Intervention/treatment
No Intervention: control group
In this group, pregnant women with HBsAg/HBeAg positive and HBV DNA > 106 copies/ml don not use any antiviral drugs during pregnancy.healthy Pregnant women with HBsAg(-), HBeAg(-)
Experimental: experimental group
pregnant women with HBsAg/HBeAg positive and HBV DNA > 106 copies/ml start to use Tenofovir Disoproxil Fumarate(TDF) antiviral treatment from the 32 weeks of gestation and drug withdrawal after delivery immediately, and drug withdrawal in the 6 weeks after delivery.
Drug: Tenofovir Disoproxil Fumarate
Tenofovir Disoproxil Fumarate was used for the experimental group of pregnancy women in the 32 weeks during pregnancy
Other Name: TDF



Primary Outcome Measures :
  1. The incidence rate of hepatitis flare after drug withdrawal in maternal postpartum [ Time Frame: after delivery 24weeks ]
    ALT > 3 times the upper limit of normal
