Filter by:A single-center, open-Label, randomized, single-dose, two-period, two-sequence, crossover study to assess the bioequivalence of test formulation entecavir tablets 1.0 mg with reference formulation entecavir tablets (Baraclude®) 1.0 mg in healthy adult subjects under fasting conditions.
Chronic infection with hepatitis B virus (HBV) is a leading cause of death in adults in sub-Saharan Africa (SSA). Prior to the introduction of the hepatitis B vaccine, main modes of transmission in SSA were perinatal transmission from mother-to-child (MTCT) (10%) and horizontal transmission during early childhood (90%). MTCT occurs through contact with maternal fluids during passage through the birth cana; transplacental transmission and transmission through breastfeeding are rare. In 2009, WHO recommended the administration of hepatitis B vaccination to all newborns within 24 hours of birth to prevent perinatal and early transmissions. In Senegal, the government introduced the monovalent vaccine that can be used within 24 hours after birth in the Expanded Program on Immunization (EPI) in March 2016. Here, we present a study protocol for a sero-epidemiological study of pairs of children aged 9 to 12 months and their mothers, identified through the demographic study, to assess the impact of monovalent vaccine introduced by the national program for prevention of mother-to-child transmission in Senegal. We will also assess the diagnostic performance of loop-mediated isothermal amplification assay (LAMP) to identify people with high viral replication (HBV DNA ≥200,000 IU/ml), compared to a conventional reference test (PCR).
1. Evaluation the safety of using human umbilical mesenchymal stem cells to treat patients with hepatitis B cirrhosis. 2. Observe the curative effect of patients with hepatitis B cirrhosis who use human umbilical mesenchymal stem cells to treat. 3. Explore the possible mechanism of human umbilical mesenchymal stem cells to treat patients with hepatitis B cirrhosis.
The " CirB-RNA " cohort aims to create a biological collection associated with clinical and biological data from patients with hepatitis B infection. This project is part of a much larger program that aims to characterize and quantify circulating viral RNAs as a possible new biomarker of hepatitis B functional cure.
Hepatitis B is one of the major public health problems in the world. According to World Health Organization (WHO) data, about 2 billion people have been in contact with the hepatitis B virus (HBV), and 257 million have chronic HBV infection. Although France is a low endemic country, with just over 280,000 people with chronic infection, hepatitis B remains a public health problem due to its morbidity and mortality. Drug users are a population at risk by their consumption practices (injection or sniffing), but also by other high-risk behaviours, particularly sexual behaviours. Prevention therefore involves securing consumption practices (sterile and single-use equipment) and protection of sexual intercourse, but also by vaccination (protecting more than 90%). Since 1982, HAS has recommended to systematically vaccinate drug users. However, according to the Marmottan study published in 2003, immunization coverage among drug addicts was already insufficient in 1999 (45.3%) and decreased again in 2000 and 2001 (15.6 and 21.7%). This decrease can be explained by the controversy around the potential link, now refuted, between vaccine against HBV and demyelination, which has stopped the mass vaccination campaign launched by the French health authorities in 1995. A study conducted between 2009 and 2012 on injecting drug users in Alsace, estimated vaccination coverage at 28%. The hypothesize is that despite the recommendations in a population at high risk of contamination, and a balance of benefits and risks in favor of vaccination, vaccination coverage against the hepatitis B virus remains insufficient among drug users because of poor vaccination acquaintance, and hepatitis B in general, in this population. Principal objective of this study is to identify non-vaccination factors against hepatitis B virus among drug users consulting at the Croix-Rousse CSAPA.
In this study, we will evaluate the incidence of hepatitis B virus reactivation within the first 6 months of treatment with rituximab, standard chemotherapy and TAF in patients with diffuse Large B-Cell Lymphoma/Chronic Lymphoid Leukemia HBsAg-positive.
The purpose of this study is to evaluate the efficacy and safety of GC1102 in combination of Nucleo(t)ide analogues (NAs) in patients with chronic hepatitis B
HBeAg-negative chronic hepatitis B (CHB) patients with low Level HBsAg were enrolled. After giving informed consent, patients were treated with nucleoside analog(s) (NAs) once a day and weekly subcutaneous injections of peginterferon alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week for 12 weeks. At week 12, the decrease of HBsAg was evaluated. ①If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/ mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. ②If the decrease of HBsAg is less than 50% compared to baseline level. The combination therapy of NAs and peginterferon alfa was extended to week 24. Then, the decrease of HBsAg was evaluated again. If the decrease of HBsAg is more than 50% compared to baseline level. NAs was stopped, patients were treated with weekly subcutaneous injections of alfa-2a 180 micrograms/week or peginterferon alfa-2b 180 micrograms/week. Treatment endpoint was HBsAg loss(＜0.05 IU/mL). Depending on the decline of HBsAg level, treatment was either continued for a prolonged period (no more than 96 weeks) until the endpoint was achieved, or terminated in week 96. After treatment, all patients were followed up for 48 weeks. If the decrease of HBsAg is less than 50% compared to baseline level. Peginterferon alfa was stopped, patients were treated with NAs once a day and then followed up for 48 weeks. Patients who maintained the original NAs treatment served as a control group.
A total of 80 adult chronic hepatitis B patients with advanced liver fibrosis (including fibrosis stage 3 and cirrhosis), who are currently on nucleot(s)ide analogs (except tenofovir alafenamide) therapy with detectable HBV DNA after 52 weeks of therapy will switch prior NUCs to TAF 25 mg/day for 96 weeks
The primary objective of this study is to evaluate the efficacy and safety of fixed dose combination (FDC) bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) in adults coinfected with both HIV-1 and hepatitis B. As this is a switch study, all eligible subjects enrolled will be switched from their current antiretroviral regimen to B/F/TAF will be followed on treatment for 48 weeks.
