Filter by:Natural Killer (NK) cells play a large role in the innate immune response as they are equipped to kill infected or tumor cells. They express a panel of activating and inhibitory receptors that regulate the destruction of the target cell. Many reports have shown that NK cell function is suppressed in CHB patients. Exhaustion occurs when activating receptors become over stimulated leading to the loss of NK function. The investigators hypothesize that NK cells are rendered dysfunctional/ exhausted by HBV. The primary objective is to determined the phenotypical modifications and mechanisms associated to NK cell dysfunction, during different phases of CHB infection, in not treated patients.
Hepatitis B virus (HBV) leads to life-threatening disease like liver failure and liver cancer. For most, a cure is unattainable as current HBV antiviral therapy (using nucleoside analogues) are not able to clear the virus from their liver. While HBV treatments are typically administered alone (monotherapy), this study will explore the use of Ribavirin in combination with standard therapy to enhance current treatment regimens. Ribavirin is commonly used to treat Hepatitis C Virus (HCV) but there is evidence that Ribavirin also induces immune effects that are beneficial in HBV treatment. The aim of this study is to determine whether combination of Ribavirin and a nucleoside analog is more effective compared to nucleoside analog treatment alone. Enrolled patients will be followed for treatment response according to standard clinical and virological tests, as well as immune response to HBV. Our ultimate goal is to find a more effective treatment and improve health outcomes for persons living with HBV.
Treatment with Tenofovir Alafenamide(TAF) in Chronic Hepatitis B (CHB) patients classified as beyond treatment indication of current international guidelines (e.g. aged more than 40 years old and 4 ≤ log HBV-DNA IU/mL < 8) is expected to bring improvement in long-term clinical outcomes. This expected result may expand the treatment indications in patients with CHB based on age and HBV-DNA in contrast to current international guidelines of CHB.
This study is a multi-center, prospective, real-world study, males and non-pregnant, non-lactating female HBeAg positive or negative patients (above 18 years of age) who were mono-infected with HBV, either NA treatment-naïve or treatment-experienced, but TAF naïve will be enrolled in this study, and they will be treated with TAF, alone or in combination with other HBV antivirals. During 36 months of treatment, efficacy and safety will be evaluated.
This is an open, uncontrolled study of twenty-five 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 ledipasvir (LDV) and sofosbuvir (SOF) 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.
This study aims to prospectively assess the repeatability and reproducibility of iron-corrected T1 (cT1), T2*, and hepatic proton density fat fraction (PDFF) quantification with multiparametric MRI using the LiverMultiScan™ (LMS, Perspectum Diagnostics, Oxford, UK) protocol across different field strengths, scanner manufacturers and models.
SHARP-P is an observational cohort study investigating the effect of direct-acting antiviral (DAA) therapy and reinfection in people with chronic hepatitis C virus (HCV) and recent injecting drug use. A prospective, observational cohort design will be used to enrol patients from correctional centres in New South Wales, Australia. Participants will be prescribed a direct-acting HCV medication as per the standard of care. The on treatment phase will vary dependent on the type of a direct-acting antiviral prescribed as per the standard of care. Once patients have completed their treatment course they will be followed up every 3 months for up to 3 years following the end of treatment phase. The study will aim to evaluate the incidence of HCV reinfection following successful DAA treatment over the three years of follow up. The study will also evaluate the proportion of patients with undetectable HCV RNA at 12 weeks post end of treatment (SVR12) with direct-acting anti-viral HCV therapy.
It remains unknown whether antiviral therapy is beneficial for chronic hepatitis B (CHB) with normal or mild ALT.The investigators aim to evaluate the antiviral indications combining liver biopsy and clinical parameters,and further clarify the response indexes of clinical results such as virological, serological, biochemical and histological responses from a retrospective observational cohort study on antiviral therapy in HBeAg positive and negative patients with different ALT levels,especially when ALT lower 2 times upper limit of normal (ULN).
Post-marketing surveillance study to evaluate the real world safety and effectiveness of Maviret (Glecaprevir/Pibrentasvir) administered under a normal, routine treatment practice by Korean patients with Chronic Hepatitis C Genotypes 1 to 6
The investigators observed the level of IL-35 secreting B regulatory (IL-35+Bregs) cells in peripheral blood cells in patients with chronic hepatitis B, and analysed the relationship between the IL-35+Bregs level and disease stage, and Th1 and Th2 cells level.
