Chronic Hepatitis BNCT02886182
Immune Function Status and the Prevalence of Hepatitis in Postpartum Pregnant Women With CHB Infection
An observational study of Chronic Hepatitis B, run by Beijing Ditan Hospital at 1 site in China.
Trial summary
To date, several studies have manifested that high levels of adrenal corticosteroids and oestrogen hormones during pregnancy can lead to increased HBV viraemia. These hormonal and immune function status changes can result in minimal fluctuations in liver function tests. Read more about this study

About this study
Official title: Immune Function Status and the Prevalence of Hepatitis in Postpartum Pregnant Women With Chronic Hepatitis B Virus Infection
To date, several studies have manifested that high levels of adrenal corticosteroids and oestrogen hormones during pregnancy can lead to increased HBV viraemia. These hormonal and immune function status changes can result in minimal fluctuations in liver function tests. Serum alanine aminotransferase (ALT) tends to increase in late pregnancy and the postpartum period. Peripartum hepatitis flares leading to hepatic decompensation have been reported.Therefore, the investigators aim to detect and observe the immune function status and incidence of hepatitis in pregnant women with chronic hepatitis B virus infection in late pregnancy and the postpartum period.To provide a clinical evidence for the administration of chronic hepatitis B virus infection pregnant women.

In this trial, pregnants who were positivity for serum HBsAg for more than 6 months and HBeAg , HBV DNA >106IU/mL, alanine aminotransferase (ALT) below 35 IU/mL (ULN=40IU/mL) and no received nucleoside analogue antiviral therapy were enrolled into group A, In addition ,the CHB infection pregnants with undetectable HBVDNA were enrolled into group B(control group).In which, all pregnants were chronic HBV infection without compensated cirrhosis,hepatic adipose infiltration,ICP, hypertension ,heart disease, postpartum hemorrhage. None of the mothers were co-infected with hepatitis A,C,D,E,or HIV;syphilis, Epstein-Barr virus.Serum HBV DNA load(Roche, Pleasanton, CA, USA), HBsAg/anti-HBs level, HBeAg/anti-HBe routine blood test, liver function, renal function will be tested piror to delivery and postpartum 2,6,12 weeks. plasmacytoid dendritic cells(pDCs) and natural killer(NK)cells,CD4＋T cells and regulatory T (Treg) cells were detected by flow cytometry. Plasma cytokines Interferon-alpha 2(IFN-α2) / Interferon-gamma (IFN-γ) / Transforming growth factor beta1 (TGF-β1) / Interleukin-2 (IL-2) / Interleukin-6 (IL-6)/Interleukin-10(IL-10) / Interleukin-17A (IL-17A) / tumor necrosis factor-α1(TNF-α1)were measured by Luminex at the above time point except 2 weeks.

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Yao Xie, MD (8610-84322489, xieyao00120184@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
the change of pDCs/ NK/CD4＋T/ Treg cells (time frame: in late pregnancy and postpartum 6,12weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Sep 2016.
