NCT02886182

Brief 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. 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.
