Evaluation of Patients With Liver Disease

The proposed study aims to evaluate, investigate, and follow-up patients suffering from acute and chronic liver disease. The study will focus on understanding diseases affecting the liver. Patients participating in the study will first undergo a routine check-up as an outpatient. They will be asked to provide blood and urine samples for laboratory testing and will undergo an ultrasound of the liver. Ultrasound examinations use sound waves to determine the size and texture of the liver. After the initial visit subjects will be requested to follow-up once a year at the outpatient department for a similar check-up. Additional tests may be requested throughout the study to provide information for other research studies and individual consent will be requested. These tests may include liver biopsies, skin biopsies, and / or specialized blood, plasma, and lymphocyte examinations. Subjects that qualify for medications presently being studied may be offered the opportunity to benefit from experimental therapy.

A Study to Evaluate Preemptive Therapy in Hepatitis C (HCV) Organ Transplant Recipients

This study is being done to determine the effectiveness of using a combination of two different drugs in preventing the transmission of HCV from a HCV positive donor to a HCV negative solid organ recipient.

The Kentucky Viral Hepatitis Treatment Study

The overarching goal of the Kentucky Viral Hepatitis Treatment Project (KeY Treat) is to increase hepatitis C virus (HCV) treatment access and delivery in a rural Appalachian community, which is in the midst of the opioid/hepatitis C (HCV) syndemic. KeY Treat is a clinical research study seeking to determine whether removing barriers (cost, insurance, specialist, abstinence) associated with accessing direct-acting antivirals (DAAs) for the treatment of HCV will impact health in Perry County, Kentucky.

Simplifying Hepatitis C Pathways for People Who Inject Drugs in Armenia, Georgia, and Tanzania

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.

Blood Collection Biorepository for Liver Disease Research

The purpose of establishing a biorepository is to provide high quality specimens (serum, plasma, buffy coat and liver tissue) for future researchers who are studying the effects that fatty liver and viral diseases have on the liver.

A Pilot Study Evaluating Safety of Sitagliptin Combined With Peg-IFN Alfa-2a + Ribavirin in Chronic Hepatitis C Patients

Hepatitis C infection is a major public health problem with nearly 175 million infected individuals worldwide. Although cure is possible, only 20-40% of patients spontaneously resolve infection and 40-80% of chronically infected patients (numbers vary depending on viral genotype) that receive pegylated-interferon-alfa2a/ribavirin therapy clear the virus and are sustained virologic responders (SVR). Still for many, the virus manages to circumvent natural immunity and current therapeutic strategies, resulting in significant morbidity and mortality. To better define the distinct clinical outcomes of HCV infection many investigators have performed candidate molecules screens or transcriptional profiling in order to identify correlates of viral clearance. One molecule that has gained significant attention is CXCL10 (also known as interferon-gamma induced protein-10 or IP-10) as an important negative prognostic biomarker. Given that CXCL10 is produced by hepatocytes and mediates chemo-attraction of activated lymphocytes expressing the CXCL10-receptor, CXCR3, it is counter-intuitive as to why this chemokine correlates with therapeutic non-responsiveness. The investigators hypothesized and have now demonstrated that CXCL10 is being cleaved in situ, resulting in the generation of an antagonist form of the chemokine. Based on the use of specific inhibitors, the investigators now propose to test whether protection of the agonist form of CXCL10 will increase responsiveness to peg-IFN-alfa2 / ribavirin therapy. This can be achieved using DPPIV inhibitors, targeting the enzyme responsible for N-terminal truncation of CXCL10. If safety is confirmed, the efficacy of DPPIV-inhibition in HCV patients will be tested in future trials that examine potential clearance benefits.

Epidemiology, Infectivity and Natural History of Hepatitis C Virus Infection

This study will evaluate hepatitis C virus (HCV) infection in blood donors who test positive for antibodies to this virus. Most HCV-infected people do not become ill and are not aware that they have hepatitis or have had it in the past. Some infected people recover completely, whereas others remain chronically infected. The study will try to define infectivity of anti-HCV positive individuals, routes of transmission of the virus, and the number of HCV-infected persons who have evidence of liver disease. Blood donors at the NIH Clinical Center or the Central Maryland Chapter of the American Red Cross who test positive for HCV may be eligible for this study. Participants will have a physical examination and history, including questions about socioeconomic status and current sexual practices. They will have 100 milliliters (ml) (6 tablespoons) of blood drawn at the first visit and 50 ml (3 tablespoons) drawn 3, 6, 9 and 12 months after the initial visit. Some participants may undergo plasmapheresis, a procedure for collecting additional plasma (the liquid portion of the blood). For this procedure, whole blood is collected through a needle placed in an arm vein. The blood circulates through a machine that separates it into its components. The plasma is then removed, and the red and white cells and platelets are returned to the body, either through the same needle used to draw the blood or through a second needle placed in the other arm. In some individuals, other body fluids (saliva, urine or semen) may also be collected. Participants may be asked to bring their household contacts and sexual partners to NIH for interview and blood testing for evidence of HCV infection and liver disease. Although this is not required for participation in the study, it would provide additional valuable information. Participants found to have chronic viral infection will be seen more often and will provide additional blood samples for routine medical care. Further medical evaluation may include X-rays or liver scans and referral to a specialist for additional tests or therapy. Ten people in this study will be recruited to participate in a secondary investigation to analyze changes in the level of HCV and the immune response to it, and to relate these changes to the degree of liver damage. In addition to blood collected for the primary study, participants in this investigation will have an additional 50 ml (3 tablespoons) of blood drawn from an arm vein every week for 10 weeks to measure levels of virus, ALT (a liver enzyme), and immune response.

Use of a Patient-Centered Electronic App to Increase ED Patient's Knowledge on HCV to Improve the HCV Care Continuum

The investigators will conduct a randomized controlled clinical trial study in an urban emergency department in Baltimore to determine the impact of an educational app which is based on Leventhal's Common-Sense Model of Illness Representations framework, on HCV-infected ED patient's hepatitis C virus (HCV) health belief and knowledge as well as the downstream outcomes of the HCV Continuum of Care (linkage to care rate, initiation of HCV antiviral treatment, and sustained virologic response). First, the investigators will develop a blueprinted prototype personalized HCV educational app which will (1) provide individualized liver fibrosis staging information, (2) pre-test HCV knowledge, perception of barriers to HCV care, and motivation to receive HCV care survey, (3) provide personalized HCV knowledge, facilitators and supporting information for HCV care via video clips and information sheets based on the pre-test results, and (4) provide post-test knowledge, perception, and motivation to receive HCV care. Second, the investigators will conduct a series of focus group discussion sessions to fine-tune the HCV educational app. Third, the investigators will enroll ED patients who have anti-HCV (newly diagnosed or previously diagnosed) but without HCV RNA testing information for a pilot randomized controlled clinical trial of the personalized HCV educational app.

The Australian HCV Point-of-Care Testing Program

The National Australian HCV Point-of-Care Testing Program will establish an observational cohort to evaluate whether scale-up of finger-stick point-of-care HCV testing increases diagnosis and treatment for HCV infection. Participants will be recruited from settings providing services to people with a risk factor for the acquisition of HCV infection (including drug treatment clinics, needle and syringe programs, homelessness settings, mental health services, prisons, and mobile outreach). Participants will attend a single visit to have their HCV RNA status tested and complete a self-administered survey. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care.

The National Australian HCV Point-of-Care Testing Program - Minimal Dataset

The National Australian HCV Point-of-Care Testing Program will establish an observational cohort to evaluate whether scale-up of finger-stick point-of-care HCV testing increases diagnosis and treatment for HCV infection. Participants will be recruited from settings providing services to people with a risk factor for the acquisition of HCV infection (including drug treatment clinics, needle and syringe programs, homelessness settings, mental health services, prisons, and mobile outreach). All participants who undergo HCV point-of-care testing at the study site will be included in the data collection. Participants will not receive treatment as a part of this study. Participants who are HCV RNA positive will be linked to standard of care.

The National Australian HCV Point-of-Care Testing Program - HCV Antibody Testing Minimal Dataset

The goal of this observational study is to learn if offering a point-of-care screening test for exposure to the Hepatitis C virus, before providing a diagnostic test for Hepatitis C infection can increase testing, diagnosis and treatment in Adults. Participants will be recruited from settings that provide services to people with a risk factor for the acquisition of Hepatitis C viral infection. The main question it aims to answer is: What proportion of the participants that have been diagnosed with HCV infection have started treatment when their records are reviewed 12 weeks after diagnosis? Participants will have one in-person visit where they will provide informed consent and receive a finger-prick rapid result test for Hepatitis C infection. Participants with no previous Hepatitis C infection will have a screening test to see if they have an immune reaction to Hepatitis C. Participants who know they have been infected with Hepatitis C in the past, and all participants with a positive screening test result will then be given a Hepatitis C diagnostic test at this visit. No treatment is provided as a part of this study, participants who are diagnosed with Hepatitis C infection will be referred to testing locations standard of care for any additional clinical assessments and treatment initiation. A review of the participant's records will be made 12 weeks after their Hepatitis C result and their treatment data are gathered.

The purpose of this study is to investigate the safety and antibody (germ fighters) response of the experimental (investigational) vaccine against HCV when injected into the arm of healthy adults.

HCV Self-testing in Georgia

Self-testing with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages.7 Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs (PWID) and men who have sex with men (MSM). In Georgia, HIV self-testing has been offered to MSM through an online platform promoting their uptake.11-12 In the present study aims to evaluate the acceptability and impact of using an online platform to enable home delivery of HCV self-testing in Georgia for PWID and MSM.

HCV Self-testing in Pakistan

To achieve the goal of elimination of hepatitis C infection in Pakistan, the strategy of elimination needs to be increasingly directed towards case finding through mass screening in rural or peri-urban communities to identify and treat those not yet aware of their infection. Self-testing (ST) with easy-to-use rapid diagnostic tests has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. In the present study we aim to evaluate the acceptability and impact of a program enabling home delivery of hepatitis C virus (HCV) self-testing in the Malir district, Karachi division, Pakistan.

HCV Self-testing in Malaysia

Self-testing with easy-to-use rapid diagnostic tests (RDTs) has been successfully used for diseases such as HIV. The availability of self-testing has been shown to increase testing rates and testing acceptability in diverse populations around the world, in large part due to its convenience and privacy advantages. Self-testing has also been effectively used to reach key populations who may not be covered by traditional healthcare programs, such as persons who inject drugs and men who have sex with men. In Malaysia, HIV self-testing has been shown to have moderate to high levels of acceptability, depending on the population, test used, and test delivery framework. In the present study we aim to evaluate the acceptability and impact of an online program enabling home-based hepatitis C virus (HCV) self-testing in Malaysia.

The main questions it aims to answer are: * How many people are offered STI self-sampling, receive a self-sampling kit, and return the collected samples for laboratory testing * What proportion of participants are recontacted and attend a consultation following the screening results Participants will receive a self-sampling kit allowing them to collect samples at home or at a place of their choice and complete a questionnaire covering socio-demographic information and information related to their sex work activity.

Identification of Hepatitis C Virus (HCV) Specific T Cells

Nearly 175 million people worldwide are infected by Hepatitis C Virus (HCV), close to 3% of the global population. Contrary to other chronic infections such as HIV, clearance of HCV is possible. While much is now known about the response to treatment in chronic HCV patients, the fact that acute HCV infection is typically asymptomatic (\~80% of patients show no clinical signs) has made it challenging to define the mechanisms involved in spontaneous clearance. Immune protection against HCV is thought to be largely dependent upon the CD8 T cell response. Therefore using the latest T cell detection technology the investigators will develop a panel of tetramers specific for all potential HCV epitopes. To produce the tetramers the investigators will utilize HLA ligand exchange technology which allows the production of very large collections of peptide-HLA multimers for T cell staining. The investigators have already performed a large scale identification of HCVg1 and HCVg4 CD8 T cell epitopes using published viral sequences and algorithm prediction databases. Using this information the investigators are currently in the process of developing collections of peptide-HLA multimers for T cell staining. Therefore the investigators require large lymphocyte pools from HCV+ patients to test both the sensitivity and accuracy of each tetramer on the CD3+CD8+ T cells. The investigators wish to examine cells from patients infected with HCV g1 and HCV g4 to be able to test and compare the frequency of possible conserved epitopes present in both HCVg1 and HCVg4 infections. Once developed this technique will allow us to examine all virus-specific CD8 T cells present in patients with acute or chronic disease, and on smaller quantities of blood. The development of these technologies will also allow us to tailor such future diagnostic tests to local populations where a viral subspecies is prevalent; for example using North-African HLA alleles for HCVg4 epitopes. The work carried out using such assays will provide important immunological correlates of viral clearance that will impact vaccine design for HCV infections. Finally, the identification of protective CD8 T cells specific for HCV may allow new diagnostic tools with predictive powers of disease progression that can be used on any flow cytometer machine.

Safety and Efficacy of Decentralized HCV Treatment vs Standard-of-Care in Rio de Janeiro (Brazil)

Up to 650,000 people in Brazil are living with chronic hepatitis c virus (HCV) infection. Hepatitis C is a silent disease, and up to 20% of cases can progress to liver cirrhosis and its complications. Rapid tests for diagnosis of HCV infection and non-invasive methods for detecting liver cirrhosis are available in the Brazilian Public Health System. Additionally, safe and highly effective drugs (direct-acting antivirals, DAAs) have been delivered for free for hepatitis C treatment by the Brazilian Unified Health System (Sistema Único de Saúde, SUS) since 2015. Sustained virological response (SVR) rates with DAAs in studies conducted in Brazil and Latin America were higher than 90%. Despite the availability of rapid tests for early diagnosis and effective drugs, the HCV continuum of care remains deficient in Brazil. It is estimated that only 10% of individuals known to have hepatitis C achieve HCV cure (SVR). This is explained by multiple barriers from diagnosis to treatment access, such as low rates of population screening (HCVST are not available in Brazil) and few available slots in tertiary centers for hepatitis C treatment by specialists. International studies have described that SVR rates by simplified hepatitis C treatment performed by non-specialists in the Primary Care System were similar to those treated in tertiary centers by specialists (standard-of-care). However, the optimal strategy for managing hepatitis C within the Brazilian-SUS remains unclear.This project aims to evaluate the improve of the HCV continuum of care by a implementation of a test-and-treat strategy in the Primary Care System in Brazil. The project consists of two parallel studies (and a sub-study). The project consists of two parallel studies (and a sub-study). Study I is a population-based cross-sectional screening study using rapid tests to determine the prevalence of HCV infection in people attending a Basic Health Care Unit. The sub-study associated with Study I is a cross-sectional study to assess the usability of a self-test for the detection of HCV antibodies in oral fluid (participants included in Study I). Study II is a phase IV open-label randomized clinical trial to evaluate the non-inferiority of simplified and decentralized hepatitis C treatment ("Simplified-and-Decentralized (SD) HCV treatment"; experimental arm) compared to specialist reference treatment ("Standard-of-Care (SC) HCV treatment"; control arm) within the SUS.

Study of the Pharmacokinetics and Safety of Glecaprevir/Pibrentasvir Initiated in Pregnancy in Women With Hepatitis C With and Without HIV

This is a Phase I/II, multi-site, open-label, single arm study to describe the pharmacokinetics (PK) and safety of glecaprevir/pibrentasvir (GLE/PIB) initiated during pregnancy in women with hepatitis C virus (HCV) infection (acute or chronic) with or without HIV and to evaluate safety for their infants through 10 weeks postpartum.

Project I Test: Implementing HIV Testing in Opioid Treatment Programs

This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).

Strategic Treatment Reduction in Very Early Liver Disease With 4 Weeks Sofosbuvir Plus Glecepravir-pibrentasvir
