Early Pregnancy, Hepatitis B Infection, Pregnant Women
Conditions
Brief summary
The goal of this clinical trial is to study the efficacy and safety of Tenofovir alafenamide (TAF) vs Tenofovir disoproxil fumarate(TDF) in early and middle pregnancy with chronic hepatitis B.
Detailed description
The goal of this clinical trial is to study the efficacy and safety of Tenofovir alafenamide (TAF) vs Tenofovir disoproxil fumarate(TDF) in early and middle pregnancy with chronic hepatitis B. Previous studies have found that TAF has good clinical efficacy in the treatment of antiviral therapy in patients with chronic hepatitis B. In order to evaluate the clinical efficacy of TAF after antiviral therapy in pregnant women with chronic hepatitis B in the first and second trimesters, the clinical efficacy of TAF after antiviral therapy was evaluated by comparing the safety (including changes in maternal ALT, bilirubin, creatinine, blood phosphorus, blood lipids, fetal malformation rate, neonatal birth defects, head circumference, height, weight, intelligence and other indicators) and effectiveness (viral load decrease, serological conversion, mother-to-fetal blockade, etc.) with the TDF group.
Interventions
Taking TAF from early or middle pregnancy
Taking TDF from early or middle pregnancy
