Filter by:Implementation and evaluation of a distribution program for low dead-space syringes/needles (LDSS/N) in Armenia, Georgia, and Tanzania, Egypt, Nigeria, Vietnam, India, Ukraine, and South Africa. This study aims to generate evidence on best practice LDSS/N distribution programs which will enhance acceptability and sustain high levels of LDSS/N uptake. People who inject drugs and access needle and syringe programs will be invited to attend up to three focus group discussion rounds (with 25 participants in each focus group round) to inform and provide feedback on a concurrent distribution program of LDSS/N. Throughout distribution, a cohort study will be run alongside distribution with 240 participants enrolled per country (with the exception of Nigeria, where 480 participants will be recruited) who will undergo HIV and HCV testing and answer surveys on their sociodemographic and behavioral status. Key informant interviews will also be held with participating staff and stakeholders to evaluate the feasibility and acceptability of this program. Primary outcomes assessed through this study include 1) community values and preferences for LDSS/N, 2) barriers and facilitators to accessing LDSS/N, 3) feasibility and effectiveness of the distribution program on increasing LDSS/N uptake, 4) model the potential public health impact and cost effectiveness of LDSS/N distribution in this setting.
This is a randomized, blinded, placebo-controlled, dose-ranging Phase 1b study of the safety, PK, and antiviral activity of ABI-4334 in treatment-naïve or off-treatment chronic Hepatitis B virus (cHBV) subjects that are Hepatitis B e antigen (HBeAg) positive or negative. The study will enroll up to 5 sequential cohorts of 10 subjects each, for a total of up to 50 subjects, randomized 8:2 to receive ABI-4334 or placebo.
Background: Autoimmune hepatitis (AIH) is a rare chronic and lifelong liver disease. Untreated, disease progresses to end-stage cirrhosis and the focus of therapy is with immunosuppression. Current therapies are limited, not targeted, and associated with side effects that patients report reduce quality of life. AIH is believed to arise as a consequence of genetic & environmental risks. Disease is characterised by impaired immunoregulation, that favours a chronic and relapsing hepatitis. As well as recognising an important role for cytotoxic T cells and regulatory T cells, it has become apparent that in AIH, as well as other related autoimmune conditions, that B-cells are important. AIH is characterised by a plasma cell rich interface hepatitis and elevated IgG concentrations. Furthermore B-cell lineages interact with regulatory T-cells. Off-label use of Rituximab, an anti-CD20 agent, has been described for patients with AIH. A number of other ways of effectively targeting B-cells in the treatment of related autoimmune diseases have also been developed, but there have been limited studies in people living with autoimmune hepatitis. Belimumab is a human monoclonal antibody that inhibits B-cell activating factor (BAFF), also known as B-lymphocyte stimulator. It is approved in the Canada to treat systemic lupus erythematosus and lupus nephritis. It has not been studied before in AIH, but off-label reports are published. In an open-label clinical trial of people living with autoimmune hepatitis, the investigator will now formally study the effect of adding Belimumab to existing standard of care, with the goal being to evaluate treatment efficacy, the ability to reduce the burden of existing therapies whilst still controlling AIH disease, and to describe the tolerability & safety of Belimumab in people with AIH. Study Design: Open label, multi-centre, Canadian clinical trial. Patient population: Patients with autoimmune hepatitis, excluding patients with decompensated liver disease, who either have active disease despite standard of care (Group A), or who are maintained with disease remission using standard of care therapy (Group B). 48 patients will be recruited. Intervention: Weekly sub-cutaneous Belimumab. Duration: 72 weeks with interim analysis after 24 patients have been treated for 24 weeks; target recruitment 48 patients. Evaluation: Safety, Serum liver tests, quality of life, exploratory immunologic biomarkers, optional liver biopsy or fine needle liver aspirate. Primary end-point: Group A: 50% or more of subjects have an ALT<2x ULN & corticosteroids at a dose of </= 5mg of Prednisone (or equivalent); Group B: 50% or more of subjects able to maintain remission (normal ALT, normal IgG) on monotherapy with Belimumab. Conclusion: Using a combination of makers of treatment efficacy and safety the investigator will test the hypothesis that Belimumab should be further formally evaluated for people living with AIH.
Hepatitis C virus (HCV) is a leading cause of morbidity and mortality worldwide. This infection continues to represent a major global public health concern. This is why the introduction of potent antivirals for the treatment of HCV has been one of the major breakthroughs of the current medical era. From a public health perspective, HCV prevalence will be eliminated if the available treatment also targets those most likely to transmit the virus. Despite this scientific advance, a systematic review from the U.S. described that of the 43% of patients aware of their HCV diagnosis, only 16% started treatment. Clearly, the long-known barriers to accessing this treatment must be broken down in order to administer these effective antivirals. The World Health Organization (WHO) has set the ambitious goal of eliminating viral hepatitis as a public health threat by 2030. This goal is really difficult to achieve, especially in low and middle-income countries. Particularly in Argentina, there is a need to improve diagnosis, access to care, and treatment of viral hepatitis. The prospect of viral hepatitis elimination in our country is daunting due to the complexity of the health system and the cost of implementing different strategies. The most pragmatic approach would be to break down national elimination targets into smaller targets for individual populations, for which treatment and prevention interventions can be delivered more quickly and efficiently. This concept is known as micro-elimination. Focusing on micro-elimination of viral hepatitis means working to achieve the WHO target in specific subpopulations. Subpopulations known to have a higher prevalence of HCV infection include prisoners, people who inject drugs, and patients requiring hemodialysis, among others. Currently, patient unawareness of HCV infection represents one of the major barriers to treatment. In many cases, the diagnosis of HCV was established many years ago and patients do not seek treatment probably because they do not recognize the urgency of treating this asymptomatic infection. It is our goal, then, to identify the group of individuals who have been diagnosed with HCV infection but are not currently undergoing regular visits with health care professionals. This strategy is now called re-linking to the medical care of patients with chronic HCV.
A prospective cross-sectional study in which surgically non-invasive sample-taking is done only for the purpose of the study. Capillary (fingerstick) whole blood and EDTA venipuncture whole blood are collected by a healthcare professional. The collected samples of capillary and EDTA whole blood are tested on iStatis and EDTA whole blood sample will be processed to obtain serum and plasma samples to be tested on the iStatis. An aliquot of the collected serum sample will be shipped to the central laboratory for confirmatory testing. The results from iStatis HBsAg Test results will not be used for patient management decisions.
Alcohol-associated hepatitis is a clinical syndrome distinct from steatohepatitis or liver cirrhosis. It is associated with high mortality and characterized by an absence of effective treatment, while corticosteroids, which are currently used as the first-line treatment are effective only in a subpopulation of patients and only on 28-days survival - their effect on survival does not last beyond this interval. The proposed study is a complex exploratory study of alcohol-associated hepatitis with several epidemiology- and prognosis-related aims.
The goal of this observational study is to clarify the clinical characteristics of autoimmune hepatitis (AIH) in China. The main questions it aims to answer are: Human leukocyte antigen (HLA) gene susceptibility in Chinese AIH patients prognostic factors associated with AIH Participants will provide liver tests results and details of treatment during follow-up.
Alcoholic hepatitis, the most florid form of alcoholic liver disease, has a very high short-term mortality of up to 50% and no specific therapies are available other than steroids. Steroids also only show a limited utility in improving the short-term survival and boast no evidence of any long-term benefits. Additionally, only a small proportion of patients with alcoholic hepatitis are eligible to receive steroids. Thus, a large number of patients are either not eligible or do not respond to steroids and this group outnumbers those who do respond to steroids, leaving us without any specific therapeutic options for a majority of these individuals.[1] Even liver transplantation is not feasible in most cases due to the presence of sepsis or recent alcohol consumption and many ethical and logistic issues are involved despite the documented safety and survival benefits of early liver transplantation in patients with severe alcoholic hepatitis (SAH) not responding to medical management.[2,8] Therefore, newer, more effective, and nontransplant therapeutic options for managing severe alcoholic hepatitis are needed. TPE is expected to be an effective and well-tolerated bridge therapy in patients with severe alcoholic hepatitis of moderate severity not improving on SMT and without immediate prospects for liver transplantation.
The goal of this observational study is to evalue the cumulative proportion of patients with OBI who do not develop HBsAg seroreversion and/or an increase of serum HBV DNA by at least 1 log above the lower limit of detection of the assay in a patient who had previously undetectable HBsAg and HBV DNA in serum during the study.
This study is a research aiming to identify knowledge , attitude and practice of population in a village in a remote governorate towards viral hepatitis B and C . It involves home visit interviews with population in this village with the use of questionnaire involving questions asked by the researcher that would be orally answered by the participants to be recorded in papers by the researcher.
