Filter by:Hepatitis C (HCV) HCV antibody assays are the standard of care test used to screen for HCV, but confirmation of acute infection is relegated in the current US guidelines to polymerase chain reaction (PCR) which often takes multiple days and may result in a loss to follow up and treatment, especially in high prevalence populations. HCV core antigen is a new, research use only immunoassay intended for use on the Abbott Alinity i system, an FDA-cleared instrument for clinical chemistry and immunoassay testing. The aim of the study is to evaluate the 48-hour stability of HCV core antigen in fresh serum and plasma specimens collected from individuals with a detectable HCV viral load (HCL VL), as per a recent antibody assay test, under multiple specimen storage conditions mirroring those employed in clinical laboratories.
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.
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.
The goal of this non-inferiority clinical trial is to evaluate the efficacy of Tappt, a novel digital medication companion solution, among individuals with hepatitis C virus (HCV) who are starting a daily oral medication regimen following standard of care in a clinical pharmacy setting. - The primary aim is to assess the non-inferiority of Tappt with medication adherence, treatment completion, sustained virologic response (SVR) assessment, and SVR achievement rates. - The secondary aim is to assess the efficacy of Tappt at enabling pharmacists to personalize treatment and management decision based on participants' reported barriers to adherence, care, and SVR achievement. Participants will download and utilize the Tappt app to record adherence to oral medication. For the purposes of this study, adherence for participants in the intervention arm will be measured using a modified medication possession ratio (MPR) measure called medication tag scan ratio (MTSR). MTSR is defined as a percentage of the number of times participants scanned their passive tags versus the total of expected tag scans based on that participant's medication regimen and treatment period. Upon study completion, a retrospective matched control will be established for the intervention group. Historic data for the matched control's adherence, treatment completion, SVR assessment, and SVR rates will be compared to the intervention arm.
Capillary blood sample results are compared to venous blood results
Sexual and gender minorities (SGM), such as gay, bisexual and other men who have sex with men (MSM) and transgender women (TGW), are at high risk of HCV infection. A recently released guideline by the WHO recommended HCVST to scale-up HCV screening. However, data on delivery-services of HCVST kits and uptake of HCV testing using HCVST remain scarce in Latin American countries. Additionally, data on the usability of HCVST in MSM/TGW, especially blood-based tests, still lacking in Brazil. To evaluate the uptake of HCV testing by the strategy of using HCVST ordered by the internet and delivery by the post in key populations (SGM) living in the metropolitan region of Rio de Janeiro (Brazil). Additionally, an Ancillary study will assess the usability of different kits of HCVST in MSM/TGW using PrEP. Study Design and Population: This protocol will be composed of two studies that will be conducted in parallel. The primary study will be a cohort study in which SGM ≥ 18 years old living in the metropolitan area of Rio de Janeiro who request HCVST will be included. The Ancillary study will be a cross-sectional study where adult MSM or TGW attending a presential visit for PrEP (initiation or follow-up) at INI/FIOCRUZ will be eligible for this study. The investigators estimate that 3,000 persons will request home-delivery of HCVST (Primary study) and 250 participants will be included in the Ancillary study.Study Design and Population: This protocol will be composed of two studies that will be conducted in parallel.

The investigators estimate that 3,000 persons will request home-delivery of HCVST (Primary study) and 250 participants will be included in the Ancillary study. Methods: For the Primary Study, a web-based platform will be built for this project and an educational campaign will be developed in dating apps to encourage HCV testing. The web platform will contain modules with information on HCV infection and a log-in to request HCV self-tests that can be delivered by the post or collected in the centralized pharmacy for HCV testing. People will be encouraged to report their HCVST results in the online platform. People with positive HCV antibody will be linked-to-care for HCV infection confirmation and treatment initiation. For the Ancillary Study, MSM/TGW attending presential visits for PrEP at INI/FIOCRUZ will be invited to perform HCVST (blood-based and oral fluid tests) under supervision of a trained healthcare worker. Participants will read written instructions and watch a video explaining the procedures step-by-step for HCVST. A second HCV test using the same kit will be performed by the healthcare worker for concordance analysis. People with positive HCV antibodies will be linked to HCV infection confirmation and treatment initiation. Data analysis: Descriptive statistical analysis will be used to evaluate the characteristics of people seeking HCVST, participant's preferences, uptake of HCV testing using self-test kits and internet technologies, as well as acceptability, usability and result interpretation of HCVST in a sub-sample of participants. Ethical considerations: Locally, ethics approval will be obtained from the INI/FIOCRUZ. International ethics clearance will be obtained from the World Health Organization Ethics Review Committee (WHO ERC). All participants will be informed of risks and benefits of the procedures and that their participation is voluntary. All participants will be required to sign the informed consent (an online agreement for Primary Study) as required by Brazilian regulations to participate in research studies. All data collected will respect The Brazilian General Data Protection Law (Law nº 13.709/2018).
The goal of this non-randomised, quasi-experimental, prospective comparative trial is to trial simplified care pathways for hepatitis C testing and treatment for people who inject drugs in Armenia, Georgia, and Tanzania. The main questions it aims to answer are: 1. What is the feasibility of implementing a hepatitis C simplified care and same-day treatment care model in community and harm reduction settings in the three study countries? 2. Does a same-day treatment initiation model involving only POC antibody tests (with a shortened read-time) increase hepatitis C treatment uptake and SVR12 outcome (cure) among people who inject drugs compared with a simplified care model involving POC antibody followed by a confirmatory RNA test? 3. What is the comparative cost-effectiveness between a same-day antibody only hepatitis C testing and treatment model and the simplified care model (POC antibody/confirmatory RNA test) model? Participants will: - be enrolled in a new simplified model of care in each country (Arm 1). After the enrolment target is met for Arm 1 (approx. 3-9 months into implementation) new participants will be enrolled into a same-day treatment trial, using presumptive treatment after a reactive POC test result at shortened read-time (5minutes) (Arm 2) - if in Arm 1, participants will commence SOF-VEL DAA treatment after receiving an RNA test to confirm current hepatitis C infection. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. - if in Arm 2, participants will begin SOF-VEL DAA treatment on the same day as the 5 minute RDT testing. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. Researchers will compare cure and participant retention rates between the two groups.
Introduction: Hepatitis C virus infection is a major cause of chronic hepatitis, cirrhosis, and liver cancer. The risk of developing cirrhosis for people with chronic infection with the virus ranges from 15% to 30% over a 20-year period. According to 2019 data from the World Health Organization there are 58 million people living with chronic hepatitis C infection. Three-quarters of those infected live in low- to middle-income countries, some of which lack budgets for screening, diagnosis and treatment campaigns. While good progress has been made in several countries, a significant gap in testing and treatment remains. Barriers to timely diagnosis include lack of awareness on the part of health professionals, availability and access to screening tests. Simplifying the cascade of care for this pathology would help ensure that more patients remain involved in the care pathway and ultimately achieve global goals. Objective: To estimate the prevalence of anti-HCV antibodies in patients with risk factors for hepatitis C virus captured by opportunity screening in the included hospital institutions. Methodology: Descriptive multicenter cross-sectional study. A total of 27160 participants among the seven institutions, 3880 per institution. Includes all persons over 18 years of age attended in the included health service provider institutions (IPS) who are users of hospitalization, emergency, outpatient and any other hospital care services. Application of a questionnaire to identify the inclusion criteria and data collection, signature of informed consent, sample collection by rapid test Abbott HCV rapid test - BIOLINE HCV and evaluation by tele-consultation by hepatologist principal investigator who will guide you to access the confirmatory test for HCV (viral load for Hepatitis C), the study will assume responsibility for its realization.
