Filter by:The primary objective of this study is to evaluate the efficacy of bulevirtide combination with pegylated interferon in participants with chronic hepatitis delta (CHD).
The purpose of this research study is to create a clinical database and bio-repository. To do this, we will obtain blood, urine, saliva, and stool samples (e.g., biological samples) and personal health information from you to use in future research studies related to alcoholic hepatitis or other diseases. Part of your blood sample will be used to extract your DNA. DNA is the genetic material that gives us unique characteristics. We are doing this research study because we are trying to find out more about how and why illnesses related to alcoholic hepatitis or other diseases occur in people. To do this, we will study the biological samples and personal health information from healthy and sick people. A "biological sample" is usually blood, but can be any body fluid. "Personal Health Information" includes such items as your name, age, gender, race, and/or your medical information. It can also include data from measurements and tests that you had while participating in another research study or that were done during the course of your regular medical care or doctor visits.
An observational double-blind cohort study that examined the association between HCV viral hepatitis, blood sugar level and systolic blood pressure in the Egyptian population
The purpose of this study was to confirm that combination of narlaprevir (NVR) and ritonavir (RTV) used as a metabolic inhibitor with pegylated interferon (PEG-INF) and ribavirin (RBV) leads to a superior Sustained Virological Response (SVR) rate compared to treatment with pegylated interferon and ribavirin in treatment-naïve and treatment failure patient populations.
The purpose of this study is to learn more about what psychological and social factors affect people in how they take their hepatitis C medications.
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).
The purpose of this research study is to test the safety, tolerability, and effectiveness of Vitamin C (ascorbic acid) intravenous infusion when used to treat alcoholic hepatitis (inflammation of the liver from heavy alcohol use) and sepsis (life-threatening complication of an infection).
Alcoholic liver disease has become one of the foremost causes of chronic liver disease across the world, and a cause of considerable morbidity and mortality. Alcoholic steatohepatitis is an entity in this broad spectrum, with severe alcoholic hepatitis transitioning to acute on chronic liver failure carrying a one month mortality of as high as 20 to 50%. The current management guidelines for severe alcoholic hepatitis show benefit with prolonged alcohol abstinence, nutritional support, the use of corticosteroids, pentoxifylline or N-acetyl cysteine (NAC) and early liver transplantation. However, major studies and meta-analyses have demonstrated that these interventions, with the exception of early liver transplantation, do not improve mortality rates to the level of statistical significance. Owing to the high short term mortality associated with severe alcoholic hepatitis, the inadequacy of a treatment that could significantly impact this short term mortality, and the limited applicability of early liver transplantation, a study on newer modalities of treatment is warranted. The role that human gut microbiota plays in health and disease is receiving considerable attention. Targeting intestinal dysbiosis, a phenomenon found to be intricately linked with the causation of alcoholic hepatitis, could provide insights into novel therapeutic strategies. Fecal microbiota transplantation is a novel approach that has gained widespread acceptance in in the management of recurrent severe Clostridium difficile infection. It's role is also being studied in other diseases where an association with gut dysbiosis has been found, such as in inflammatory bowel disease and irritable bowel syndrome. The role of FMT has also been studied in liver diseases such as non-alcoholic fatty liver disease (NAFLD), liver cirrhosis and primary sclerosing cholangitis. In this process, a diseased recipient is transferred fecal material containing the microflora of a healthy individual. It limits the colonization of pathogens, inducing colonization resistance, affects microbiota composition in the gut, as well as metabolism in the microbial pathogens. FMT helps alleviate gut dysbiosis and restores gut microbial diversity. Our aim is to evaluate the role of FMT on short term survival and improvement in scores of prognostic significance (CTP, MELD, MELDNa, mDF) in patients with severe alcoholic hepatitis.
This is a Phase I double-blind, randomized, placebo controlled trial (1:4 ratio of placebo to vaccine) of Hepatitis E virus vaccine containing a 239 amino acid subfragment of Hecolin(R) (HEV-239) in 25 US males and non-pregnant females ages 18 - 45 (inclusive) to assess the safety, reactogenicity, and immunogenicity of HEV-239. Subjects will receive 3 doses of study product on Days 1, 29, and 180. Subjects will remain in the study for up to 13 months (including screening). The study duration will be approximately 15 months. Subjects will be observed for 30 minutes after vaccination. The occurrence of solicited injection site and systemic reactogenicity events will be measured from the time of study vaccination through Day 8 after each vaccination. These will be ascertained through use of an electronic memory (e-memory) aid, a telephone call on day 4 after each dose of vaccine, a Day 8 clinic visit, and potentially at the Day 15 clinic visit after each dose of vaccine. Unsolicited adverse events will be collected from vaccination through Day 29 after each vaccination. Serious adverse events will be collected from the time of the first study vaccination through the last study visit (Day 360). The study includes multiple phlebotomy time points for immunogenicity and blood collection for future use at visit 1 and Days 8, 15, and 29 after each vaccination. The durability of the immune response and future use collection will be assessed at 5 months after the first boost (Day 180) and at 6 months after the second boost (Day 360). The primary objectives of the study are to; 1) assess the safety and reactogenicity of HEV-239 following delivery of each vaccine dose; and 2) assess the number of subjects with > / = 4 fold rise in Hepatitis E virus (HEV) immunoglobulin G (IgG) at any time after vaccination.
