Filter by:Chronic hepatitis C virus (HCV) infection, an important cause of morbidity and mortality worldwide, is a significant problem in kidney transplant recipients (KTRs) given its high prevalence in patients undergoing hemodialysis. Interferon based regimens were cornerstone of treatment of HCV infection in the past; however, due to their low efficacy and high rates of adverse effects, they have been abandoned in the new era of direct acting antivirals (DAAs). Several studies demonstrated the efficacy and safety of DAAs, yet data regarding clinical practice of these agents in KTRs is still needed. Therefore, we conducted a study using our registry data to evaluate the efficacy and safety of DAAs in KTRs.
This study seeks to assess the effectiveness of Glecaprevir plus Pibrentasvir in participants with chronic hepatitis C in a real-life setting across clinical practice populations in the Russian Federation.
Though HAV is mainly transmitted through the fecal-oral route, infection by sexual intercourse and blood transfusion is also possible. Injection drug users (IDUs) and men who have sex with men (MSM) have a higher risk of acquiring HAV due to their behaviors. Reemerging threat of hepatitis A among MSM in Taiwan has been reported recently. Based on the guidelines for the diagnosis and treatment of HIV/AIDS and the Advisory Committee on Immunization Practices (ACIP), Taiwan, vaccination of individuals against HAV with any of the following indications is recommended: HIV patients, adults with chronic hepatic disease, hemophilia, liver transplantation, occupational exposure, MSM, persons who use injection or noninjection illicit drugs, or persons traveling to or working in countries that have endemicity of HAV. In HIV-infected patients, the immunogenicity to HAV vaccination is sub-optimal in HIV-infected patients and the seroconversion rate is estimated 68-90% after administration of 2 or 3 doses of HAV vaccine. Furthermore, the antibody titers of HIV-infected patients following HAV vaccination are significantly lower compared to those of HIV-uninfected persons. The sub-optimal response among HIV-infected subjects remains an unresolved problem. In this study, the investigators aim to determine the to conduct a randomized clinical trial to compare the immunogenicity of 2 different doses of HAV vaccination (1 dose versus 2 doses) in HIV-infected patients who failed to achieve serologic response in the primary vaccination. This proposal will provide the solid evidence to elucidate the role of booster HAV vaccination in HIV-infected patients without response to primary HAV vaccination.
The primary objective of this study is to evaluate the efficacy of bulevirtide combination with pegylated interferon in participants with chronic hepatitis delta (CHD).
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.
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).
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.
This is an interventional, non-randomized, controlled prospective study to treat HCV in mono-infected and HIV co-infected individuals and compare cardiovascular risk outcomes to HIV mono-infected controls. This pilot study will demonstrate whether functional cure of HCV reduces myocardial injury and risk of cardiovascular disease.
