The Study of Short-range Antiviral Treatment During Pregnancy to Block Mother-to-child Transmission...

Chronic Hepatitis B

Pregnant women carry high HBV DNA loads before delivery, which is the most important factor leading to mother-to-child transmission of HBV. Nucleoside analogue antiviral treatment during late pregnancy can significantly reduce the incidence of HBV MTCT, but security problems of using NA treatment during pregnancy has not been eliminated, Therefore, the aim of our study is to explore the effect of starting to use Tenofovir Disoproxil Fumarate(TDF) antiviral treatment from the 32 weeks of gestation to block mother-to-child transmission of hepatitis B virus(HBV MTCT).

A Prospective,Observational Follow-up Study of Nucleoside Treated Patients With Chronic Hepatitis...

Hepatitis BChronic

This is a prospective, multicentre observational follow-up study of PegIFN treatment unstained response in nucleoside experienced patients with Chronic Hepatitis B.Patients will join this study after finished following clinical trail about A Study of Combination or Sequential Treatment With PEGASYS (Peginterferon Alfa-2a) and Entecavir in Patients With HBeAg Positive Chronic Hepatitis B(OSST trail),A Real-World Study of Pegylated Interferon In Nucleoside-treated Patients With Chronic Hepatitis B (COST study), Combination Therapy With Interferon Plus Interleukin 2 and Hepatitis B Vaccine in Chronic Hepatitis B Patients(Endeavor study),A Prospective Clinical Trial in Chronic Hepatitis B Patients Nucleotide Analogues Experienced (Anchor A Study),Sequential/Combination Therapy in Nucleoside or Nucleotide Analogue (NA)-Suppressed Chronic Hepatitis B Patients (NPGV study).We plan to compare the HBsAg negative rate and maintenance rate,the occurrence of liver cirrhosis and the occurrence rate of hepatocellular carcinoma(HCC) related to hepatitis B virus(HBV) within five years between interferon group (including interferon alone or interferon combined with other drugs) and nucleoside analogues.Patients were divided into two groups based on whether they received interferon or not.

Switching From Tenofovir Disoproxi Fumarate to Tenofovir Alafenamide in Chronic Hepatitis B Patients...

Hepatitis BAntiviral Drug Adverse Reaction

To evaluate the efficacy of switching to tenofovir alafenamide (TAF) 25 mg QD versus continued tenofovir disoproxil fumarate (TDF) 300 mg QD in CHB patients with antiviral resistance, as determined by the proportion of virologically suppressed patients at week 48 To evaluate the safety and tolerability of switching to TAF 25 mg QD versus continuing TDF 300 mg QD in antiviral-resistant subjects with chronic HBV at week 48

A Clinical Research on Disease Progression and Intervention of Chronic HepatitisB

Hepatitis BChronic

HBV(hepatitis B virus) with metabolic comorbidities may accelerate liver disease progression and increase the risk of HCC(Hepatocellular Carcinoma)development. It is reported combination of metabolic diseases and CHB is associated with substantially increased rates of liver cirrhosis and secondary liver-related events compared to CHB alone. Consequently, hepatitis B patients with metabolic comorbidities warrant particular attention in disease surveillance and evaluation of treatment indications.

Effort to Narrow the Gap Between in Accordance With Guidelines and Consent to Treat CHB Population...

Chronic Hepatitis b

China has the world's largest burden of hepatitis B virus (HBV) infection and will be a major contributor towards the global elimination of hepatitis B disease by 2030. One of the main issues in the management of patients with chronic HBV infection (CHB) is to maximize the individuals who need the treatment engaged and retained in care. However, our investigation revealed that 21.1% patients were treatment eligible but not treated based on Chinese 2019 CHB treatment guidelines, while only 213 (13.9%) patients were indicated-but-not-treated according to AASLD 2018 Hepatitis B guidance in a real-life cohort study. To maximize the individuals who need the treatment engaged and retained in care, integrated intervention strategies to address these treatment barriers are urgently needed. Therefore, we aim to propose a study to narrow the gap between in accordance with guidelines and consent to treat CHB population in EAST of China.

Off-therapy Response After Stopping Entecavir or Tenofovir

Chronic Hepatitis b

Pegylated-interferon (Peg-IFN) α-2a, entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are current recommended first-line antiviral therapies for chronic hepatitis B (CHB). Compared with Peg-IFN therapy, nucleot(s)ide analogue (NUC) therapy has the advantages of having a potent antiviral effect, and good tolerance without side effect. The long-term safety and efficacy of ETV and TDF therapy had also been identified. However, poor durability of the effectiveness after stopping NUC therapy are encountered in the majority of patients. Previous study identified a high HBV relapse rate of over 50% in HBeAg- positive CHB patients treated with lamivudine. A recent study investigating the post-treatment durability of ETV showed that higher to 45.3% of the HBeAg-negative CHB patients happened a clinical relapse within 1-year after stopping ETV therapy. TDF is another recommended first line NUC with high potency and high genetic barrier. Although the efficacy of long-term TDF therapy had been identified, there is lack of data regarding the off-therapy response in CHB patients with TDF therapy currently. Only a small scale of patients treated with TDF were included in a recent study investigating off-therapy relapse in non-cirrhotic HBeAg-negative CHB patients after greater than 4 years of NUC therapy. In addition, the factors associated with off-therapy response are also still uncertain. The investigators plan to enrolled 400 CHB patients who had received oral antiviral therapy ETV or TDF and achieved the Asia Pacific association of the study of liver (APASL) criteria of stopping NUC therapy. The aims of the study are to investigate the rate of HBV relapse including virological and clinical relapse in all and between patients with ETV and TDF therapy, and to identify the predictive factors of relapse.
