Filter by:This is a multi-centre prospective longitudinal cohort study with the aim of collecting and storing clinical data, patient blood, DNA and PBMCs to examine outcomes related to drug resistance, drug monitoring and host genetics in the era of directly acting antiviral drugs for hepatitis C therapy.
The purpose of the study is to assess how feasible it is to treat and prevent the transmission of Hepatitis C in the prison setting to achieve substantial reductions in the incidence and prevalence of Hepatitis C. It is hypothesised that a rapid scale-up of Hepatitis C Virus (HCV) treatment with interferon-free Direct Acting Anti-virals (DAAs) in prison inmates will achieve a >50% reduction in the incidence of HCV infection over a two year period in the prison setting.
This is an open label, dose ranging, phase1a/1b clinical trial to study the safety, Pharmacokinetics and Pharmacodynamics of Peglamda 60, 120, 180 and 240 mcg in healthy volunteers and antiviral activity of once weekly Peglamda administration in combination with daily Ribavirin in Hepatitis C naive patients up to 4 weeks period. The objective of the study to establish safety, PK/PD data on healthy subjects and preliminary efficacy and safety in Hepatitis C naive patients.
Vaccines are one of our most effective public health tools but many who need them don't respond well and are not protected. Adjuvants boost immune responses and are commonly included in vaccine preparations. Bisphosphonates are the most commonly prescribed treatment for osteoporosis and may represent a new class of adjuvant. Bisphosphonates are well tolerated with chronic administration and have very few adverse effects. Research suggests that these medications can stimulate the immune system. Bisphosphonates are of special interest in populations with impaired immunity and an inability to amount protective antibody responses following immunizations. We propose a pilot study to evaluate the clinical relevance of this finding in humans. We will study the effect of bisphosphonates on quantitative humoral immune response to hepatitis B vaccine in healthy older volunteers who have not previously received this vaccine.
Evidence suggests that vitamin D may be directly or indirectly a co-factor for the efficacy of Hepatitis C virus, (HCV), antiviral therapies. The level of vitamin D necessary for optimum immune function is ill defined and many of those with HCV infection in Scotland are below these levels. Vitamin D is a cheap and safe medication, so its addition to anti-viral therapy should be highly cost-effective even if only a modest increase in SVR was achieved. Given the Scottish HCV epidemic, the world leading government response to it and the nationally low vitamin D levels, Scotland is perfectly placed to answer this question. Therefore the investigators hypothesize that vitamin D supplementation will improve SVR and propose a randomised controlled trial to test this hypothesis. The anticipated end of study date for this study is April 2015
The purpose of this study is to assess the long-term persistence of immunity to hepatitis B in adolescents aged 12-13 years who were vaccinated with four doses of Infanrix™-Hexa in infancy and to assess the anamnestic response, immunogenicity, safety and reactogenicity of a single challenge dose of the hepatitis B vaccine Engerix™-B Kinder.
The purpose of this study is to determine whether a salt restriction diet improves immune parameters in patients with autoimmune hepatitis.
Liver fibrosis is an important public health problem, with a substantial morbidity and mortality due to progression to cirrhosis and hepatocellular carcinoma. All causes of chronic liver disease may lead to fibrosis. The traditional diagnostic approach requires a biopsy for assessing the severity of liver disease prior to therapy. However, liver biopsy has several limitations: cost, sampling error, and procedure-related morbidity and mortality. Considering the high prevalence of viral hepatitis and nonalcoholic fatty liver disease, a condition often associated with obesity and type 2 diabetes, there is an urgent need for noninvasive screening, diagnosis and monitoring strategies of chronic liver disease severity. Our team has the expertise to investigate ultrasound-based and magnetic resonance-based elastographic methods for the noninvasive staging of liver fibrosis. The primary objective of this cross-sectional study is to compare the sensitivity of elastographic methods for detecting histology-determined significant fibrosis. The secondary objectives are to compare the diagnostic accuracy of these elastographic methods and the influence of potential confounders (inflammation, steatosis and iron deposition) on their diagnostic accuracy.
HBV can be transmitted from mother-to-child, with a risk increasing according to maternal HBV DNA during pregnancy. HDV is a defective virus using HBs Ag for its own replication. Nucleosides analogues have only a minor impact on quantitative HBs Ag level. Data about vertical HDV transmission are old, justifying a new study.
A study of the efficacy and safety of the combination of daclatasvir and sofosbuvir in the treatment of hepatitis C virus and HIV coinfection.
