Filter by:Infection and cancer is a major cause of death and morbidity, and may be preventable through vaccination. It is not fully understood at the molecular level why some people respond better than others to vaccines until now the technology to assess this has not been available. This has impaired vaccine development. The overall goal of the Human Vaccines Project is to understand the 'rules' of how vaccines work. In this demonstration project the investigators will vaccinate healthy adults with hepatitis B vaccine to start to understand better how it works, ultimately helping with rational vaccine design in the future.
This is an open, uncontrolled pilot study of thirty chronic HCV infected patients carried out at Yassin Abdel Ghaffar Charity Center for Liver Disease and Research. The aim of this study is to investigate the safety & efficacy of combined therapy sofosbuvir (SOF) and daclatasvir (DCV) for treating HCV Genotype 4 in children aged 8 to 18. Due to previous positive results in other clinical studies of this drug it is expected that the drug will have high safety and high efficacy. Safety will be measured by checking for adverse effects, while efficacy will be measured by Real-Time Quantitative Polymerase Chain Reaction (qPCR) detecting viral nucleic acids in blood samples.
The primary objectives of this study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks in adults with chronic hepatitis C virus (HCV) infection.
This was a Phase 3b, open-label, non-randomized, multicenter study to evaluate the efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) in participants with chronic hepatitis C virus (HCV) genotype (GT) 1 - 6 infection without liver cirrhosis or with compensated liver cirrhosis and with chronic renal impairment in participants who were either HCV treatment-naïve (TN) or prior treatment-experienced (TE) with interferon (IFN) or pegylated interferon (PegIFN) with or without ribavirin (RBV), or sofosbuvir (SOF) plus RBV with or without pegIFN.
149 HBV carriers with inadequate serum vitamin D levels were randomized to two groups: one is supplied with vitamin D and another without as controls. The markers of HBV replication were compared before and after treatment.
The objectives of this study are to assess the pharmacokinetics, safety, and efficacy of glecaprevir/pibrentasvir adult formulation in adolescents ages 12 to 17 years and a pediatric formulation of glecaprevir and pibrentasvir in children ages 3 to < 12 years.
Sofosbuvir is the base of most treatment regimens for hepatitis C. In patients with renal failure the blood level of one of its metabolites (GS-331007) rises up to 20 folds. Although no particular adverse event has been linked to this metabolite sofosbuvir is not recommended for patients with renal failure mainly because of lack of data. Nevertheless there are anecdotal reports and small studies proving the safety of sofosbuvir in renal failure. This study addresses this lack of information by evaluating the safety and efficacy of sofosbuvir and daclatasvir in treating hepatitis C in 100 patients with renal failure.
Recently,surprisingly and unexpectedly increased aggressiveness and high rates of HCC recurrence (28%(16/58) and 29%(17/59), respectively) have been reported in patients who cleared HCV with DAAs after achieving a complete response to resection or local ablation within only 6 months of therapy. The authors hypothesized that the rapid eradication of HCV and control of liver inflammation would impact anti-tumoral immune control, which in turn might contribute to the neoplastic cells proliferation. Conversely, three independent prospective French cohorts failed to reveal an increased risk of HCC recurrence after DAAs treatment in CHC patients after receiving curative cancer treatments.Although the impact of DAAs treatment on the rate of HCC occurrence or recurrence still remain unclear, it would be more important to pay attention to the immunological changes of CHC patients treated with DAAs.Up to now, little was known about the immunological changes of chronic hepatitis C (CHC) patients treated with direct-acting antiviral agents (DAAs), here we try to explore the effect of antiviral treatment of CHC patients with DAAs on the frequency of monocytes, NK cells and cytokines that promote their activation.
Incorporating Hepatitis C Virus (HCV) treatment into opioid maintenance treatment program clinical protocols is an innovative health care delivery model that has been associated with improved HCV treatment uptake in non-pregnant, drug-using populations. This "medical home" approach would combine HCV and opioid maintenance treatment into one treatment regimen and incorporate the expertise of obstetricians, hepatologists, substance abuse treatment providers and pediatricians into one comprehensive clinical care model. The purpose of this study is to evaluate the feasibility/acceptability of a combined, peripartum HCV and opioid maintenance treatment program on adherence to HCV treatment regimens and evaluate the rate of intravenous drug use (IVDU) recidivism, HCV reinfection and health related Quality of Life (QOL) in women with opioid use disorder (OUD) during the first postpartum year. The protocol involves three separate study phases. All 3 study phases will occur with support from hepatology providers at Magee-Womens Hospital. Phase 1 involves screening, enrollment and a baseline assessment of liver function, HCV infection (genotype, viral load) and blood and urine studies in HCV-infected patients during pregnancy. In Phase 2, subjects will undergo 12 weeks of sofosbuvir/velpatasvir therapy initiated at 2 weeks postpartum. Feasibility/acceptability and adherence to sofosbuvir/velpatasvir will be assessed at 4, 8 and 12 weeks of therapy. In Phase 3, subjects will continue to be followed for 15 months after treatment completion. Treatment effectiveness and sustained virologic response (SVR) will be evaluated at 3 months and rates of IVDU recidivism, HCV reinfection and patient centered outcomes such as health related quality of life (QOL) will be assessed at 6, 9 and 12 months following treatment completion.
This is a pilot feasibility study of a small randomized controlled trial (RCT)design to evaluate participation in a Cognitive Behavioral Coping Skills (CBCS) group intervention versus standard of care in patients with hepatitis C undergoing antiviral treatment. The primary objectives are to (1) examine effect size (ES) estimates of key outcomes to provide essential data to inform a larger efficacy trial, (2) determine whether clinically significant improvements occurred in any key outcomes, and (3) evaluate study feasibility and patient acceptability. Study findings will inform a larger efficacy study of the CBCS-HCV.
