Filter by:Title Reaching out to the UNdiagnosed people infected with blood-borne viral infections (RUNtoBBV) Objectives 1. To study the efficacy of an outreach methodology to increase the uptake for screening, linkage to care and treatment in (active or former) people who use drugs (PWUD) Trial design Prospective multicenter interventional cohort design Number of subjects 336 inclusions (with prevalence of HCV Ab: 30%) - 168 Antwerp - 168 Limburg Selection criteria Inclusion criteria: - 18 years of age - History of/ or active drug use - Written informed consent obtained Exclusion criteria - Currently enrolled in centralized OST program of Free Clinic or CAD Limburg Endpoints The following endpoints will be compared between the centers in Limburg and Antwerp: (Main outcome in bold) Main objectives: - Prevalence of blood-borne viral infections in Belgian (former or active) PWUD: - HCV infection (number of HCV Ab+ / number of screened PWUD) - HBV infection (number of HBsAg+/number of screened PWUD) - HIV infection (number of HIV Ab+/number of screened PWUD) - Analysis of linkage to care to hepatologist/ infectiologist (number of patients who adhered to their consultation/number of referred patients) Secondary objectives: - Analysis of risk behavior/sociodemographics linked to presence of BBV infections - Analysis of uptake of anti(retro)viral treatment (number of patients started on treatment/number of patients needing treatment) - Analysis of treatment adherence (adherence to treatment consultations/total planned consultations) - Analysis of treatment outcome (total number of cured or virally suppressed patients/total number of treated patients)
The study aims to evaluate the effect of allogeneic mesenchymal stem cell therapy on patients who suffered from liver cirrhosis caused by Hepatitis B.
The purpose of this study is to study the risk of hepatitis flare in patients with previous hepatitis B virus exposure amongst patients on immunosuppressive and biological modifier therapies
International migration to Chile has sharply increased since 2010. Particularly, Haitian migration now totals approximately 200.000 people. Preliminary results show a high prevalence of hepatitis B infection in this population. Approximately 35% of adult Haitian migrants in Chile have been exposed to hepatitis B infection. In this study the investigators aim to study the clinical and molecular characteristics of this infection and also to assess the serological response to an accelerated schedule of hepatitis B vaccination (0, 1 and 2 months).
Chronic Hepatitis B virus (HBV) infection is a neglected disease with devastating consequences, particularly in countries with limited resources for the health sector. Mother-to-child-transmission (MTCT) is responsible for around 50 % of the HBV infections in Tanzania which, in 90 % of the cases, lead to a chronic HBV infection of the child. This infection rate could be reduced with an active immunization directly after birth which is recommended by the World Health Organization (WHO). However, the Tanzanian national immunization programme schedules the first Hepatitis B vaccination for the fourth week after birth which is too late to prevent a perinatal transmission. The aim of the study is to determine the prevalence of Hepatitis B surface antigen (HBsAg) in pregnant women in rural and urban study sites in the region of Mwanza, Tanzania. The blood from the positive -testing mothers should be further examined for viral load, genotype of the virus and for liver transaminases in order to conceive a better understanding of the progression of the infection. Beside the laboratory parameters, risk factors for the infection should be determined with the use of a questionnaire. Furthermore we would like to assess the number of children who were already infected, during the intrauterine period or during birth.
The effect of anti-tumor treatment is not satisfying in HBV-related hepatocellular carcinoma (HBV-HCC) for reasons that HBV-HCC carries highly heterogeneous antigens to facilitate cancer cells escaping from immune surveillance and constructs an immunosuppressive microenvironment. Correspondingly, multiple signals loaded dendritic cells vaccine can efficiently present T cells with antigens of HCC sensitize their antitumor properties meanwhile low dose cyclophosphamide (CY) can effectively improve the microenvironment of immunity. Therefore, we put forward a new scientific therapy called "multiple signals loaded dendritic cells vaccine combined low dose of cyclophosphamide" combining with radical surgery or TACE or targeted agents for patients with hepatocellular carcinoma to prolong their survival time.
This study is to investigate the long-term outcomes and prognostic risk factors in patients recovered from hepatitis B virus related acute on-chronic liver failure.
The primary objective is to evaluate the safety and tolerability of single oral doses of NCO-48 Fumarate in healthy subjects. The secondary objectives are to evaluate the pharmacokinetic (PK) profile of NCO-48 Fumarate and its active metabolite, tenofovir (TFV), in healthy subjects following single oral doses and to evaluate the effect of food on the PK of a 30 mg dose of NCO-48 Fumarate in healthy subjects.
This was a retrospective observational cohort study. The patients with chronic hepatitis B and cirrhosis who were treated with antiviral therapy in the Second Department of Liver Disease, Beijing Ditan Hospital, Capital Medical University from October 2008 to April 2020 were enrolled. Patients treated with antiviral drugs including interferon and/or nucleoside (acid) analogues lasting more than 6 months were included in the study. Interferon, nucleoside (acid) analogue monotherapy, combination therapy, sequential therapy, maintenance therapy and drug withdrawal therapy can all be included in the study. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe, biochemical indexes, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline), during treatment and after treatment. The virological response and clinical outcome after antiviral treatment for chronic hepatitis B were observed for at least 288 weeks, and the main evaluation indicators were the occurrence or reversal of cirrhosis complications, hepatocellular carcinoma and mortality. Secondary evaluation index: the influence factors of different clinical outcomes. To investigate the long-term virological response and clinical outcome of antiviral therapy in patients with chronic hepatitis B and liver cirrhosis and to clarify its influencing factors.
This is a Phase 1, first in human study of ChAdOx1-HBV. The study will be conducted in 40 healthy participants and 12 participants with CHB and virally suppressed with oral antiviral medication. This will be an open-label, non randomised dose escalation study comparing the safety, tolerability and immunogenicity of 2 different doses of ChAdOx1 HBV vaccine. T cell responses in healthy participants who have received a prior two-dose series of AZD1222 will be compared with those who have received either the Pfizer COVID 19 vaccine or the Moderna mRNA COVID 19 vaccine.
