Filter by:Background: Chronic hepatitis B virus (HBV) infection affects 292 million people worldwide; 887,000 die each year from cirrhosis, liver cancer, and related issues. Treatment options are limited. Objective: To test 2 drugs (VIR-2218 and peginterferon) in people with mild or inactive HBV infection. Eligibility: People aged 18 to 65 years with mild or inactive HBV infection. Design: Participants will be screened. They will have blood tests and an eye exam. They will have imaging scans of the liver to check the health of the liver. Participants will be in the study for over 2 years. VIR-2218 is an injection given under the skin of the stomach, upper arm, or thigh. Participants will come to the clinic to receive this injection once a month for 6 months. Peginterferon is also injected under the skin. Participants will have this shot once a week for 6 months. They may either inject themselves at home or come to the clinic to get the injections. Participants will get just the VIR-2218 for 3 months, then both shots for 3 months, then just the peginterferon for 3 months. Participants will have two 3-day stays in the hospital. Tests will include: Liver biopsy. A sample of tissue will be taken from their liver. After the procedure, participants will lie on their right side for 2 hours and then on their back for 4 hours. Fine needle aspiration. A small needle will be used to collect cells from the liver. After the last injection of peginterferon, follow-up visits will continue in the outpatient clinic every 4 to 12 weeks.
The goal of this observational study is to evaluate the effectiveness of the carnitine-orotate complex and biphenyl dimethyl dicarboxylate in the adjuvant therapy of chronic hepatitis D in real clinical practice: a prospective cohort study
Elimination of mother-to-child-transmission (EMTCT) of HIV, syphilis and hepatitis B are key priorities in Indonesia, the fourth most populous country in the world. Despite national guidelines and strong antenatal care attendance, coverage of antenatal screening for these diseases among pregnant women remains extremely limited in Indonesia. The Indonesian government is committed to improving the integration of HIV/syphilis/hepatitis B testing and treatment into the antenatal platform but currently lacks comprehensive evidence on interventions to support this. We will evaluate a low-cost and locally driven intervention based on the principles of continuous quality improvement to strengthen antenatal care and promote screening for HIV, syphilis and hepatitis B. Continuous Quality Improvement (CQI), which involves local antenatal care (ANC) teams systematically collecting and reflecting on local data to inform the design and implementation of service delivery, has been effectively used to strengthen ANC in a number of Sub-Saharan African countries but yet to be comprehensively evaluated in ANC services in Indonesia. This approach holds considerable promise for Indonesia, a highly populous and diverse country where a 'one size fits all' approach to the delivery of quality ANC rarely applies.
Establishment and validation of the non-invasive model to predict antiviral therapy in the gray zone of chronic hepatitis B
Some patients with low-level viremia (LLV) are also likely to develop hepatocellular carcinoma (HCC) or other liver diseases. The relationship between HBV RNA levels and fibrosis in patients with HBV DNA negative or LLV is still lacking evidence. The purpose of this study is to observe the differences in HBV RNA levels and their association with efficacy in HBV DNA negative or LLV patients. Investigators conduct the prospective, single-center, non-randomized, observational clinical study. A total of 100 chronic hepatitis B (CHB) patients who receive antiviral therapy with nucleoside (acid) analogues for 1-3 years will be enrolled. The enrolled patients will be followed up five times to collect clinical data and record adverse events (at baseline, week 12, week 24, week 36 and week 48, respectively).
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract that includes ulcerative colitis (UC) and Crohn's disease (CD) . They mainly affect young populations, altering their quality of life and increasing morbidity, compared to the general population . The etiology and pathogenesis of IBD are still poorly understood. Inflammatory bowel disease (IBD) patients are at an increased risk of contracting and developing complications from hepatitis B virus (HBV) due to their weakened immune systems and frequent use of immunosuppressive medications. The traditional HBV vaccine regimen requires three doses over six months to achieve full immunity, which can be challenging for IBD patients who may have difficulty adhering to the schedule or may not respond well to the vaccine
The goal of this prospective, exploratory, non-intervention, multi-center, real-world study is to investigate the predictive value of HBV pgRNA in the occurrence of long-term outcomes under antiviral therapy in patients with chronic hepatitis B. Participants will take the necessary clinical examination and blood draw during the patient's treatment and follow-up, and all the treatment is determined by clinicians.
This is a single-center, randomized, active-controlled, parallel-design, double-blind, phase I study to evaluate the safety and immunogenicity of a single dose of APV006 in healthy adults.
The goal of this clinical trial is to evaluate the safety and tolerability of multiple doses of human umbilical cord mesenchymal stem cell injection in patients with decompensated hepatitis B cirrhosis, and to further explore the efficacy, pharmacodynamic profile and appropriate dose of administration to provide a basis for the use of safer and more effective treatments for patients with decompensated hepatitis B cirrhosis in the future. Participants are required to sign an informed consent form and, after undergoing a series of tests and meeting the protocol's entry and exclusion criteria, are assigned to a dose group for intravenous infusion of human umbilical cord mesenchymal stem cells.
Aim of the work: 1. Evaluate efficacy and safety of Intralesional HBV vaccine injection as a treatment of plane and genital warts. 2. Evaluate efficacy and safety of Intramuscular HBV vaccine injection as a treatment of plane and genital warts. 3. Compare the efficacy of different doses(0.3ml vs 0.5ml )of intralesional HBV vaccine injection for treatment of plane and genital warts. 4. Compare the efficacy of intralesional HBV vaccine injection vs Intramuscular HBV vaccine injection in treatment of plane and genital warts.
