Filter by:This is a controlled study intended to evaluate the usability, label comprehension and performance of the INSTI® HCV Self Test in the hands of untrained lay users using fingerstick blood, with instructions for use specifically designed for a lay person who has not used any hepatitis C rapid self test prior to the study and to assess "lay" users ability to comprehend key concepts and information provided on the outside of the pouch and in the accompanying Instructions for Use. Comprehension will be assessed without product familiarization (demonstration/training) by a healthcare professional.
Pregnant adults over the age of 18 who are seen in the Washington University obstetrics and gynecology, maternal fetal medicine or infectious diseases clinic or admitted to BJH with hepatitis C virus infection who have a history of past or current drug use Participant Duration: Approximately 1 year. Aims: Aim 1 - Evaluate adherence and treatment completion rates when glecaprevir-pibrentasvir is started during pregnancy for women who use drugs. Aim 2 - Evaluate patient experience with hepatitis C virus treatment during pregnancy.
This is an observational, retrospective & prospective cohort study. The retrospective element of the study is a chart review to identify people with diagnosed but untreated HCV and re-link them to care. The observational prospective cohort element of the study will examine the HCV linkage to care, treatment initiation, treatment completion & cure rates of these HCV clients achieved through this chart review and re-linking approach.
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.
Hepatitis C virus (HCV) infection remains a significant health problem in our country. The World Health Organization estimated that 71 million people worldwide had chronic HCV infection in 2015. And 399,000 people died from cirrhosis or primary hepatocellular carcinoma caused by HCV infection. In 2006, the positive rate of HCV antibody in the population aged 1-59 was 0.43%. Therefore, it was estimated that there were about 5.6 million HCV infected people in the general population, and about 10 million cases of HCV infected people in high-risk groups and high incidence areas. Universal genotype direct antiviral agent (DAA) is the preferred antiviral therapy for hepatitis C. Sofosbuvir/velpatasvir are direct antiviral agents for hepatitis C. The results of Asian clinical trials mainly in Chinese population showed that the sustained virologic response (SVR) rates of sofosbuvir/velpatasvir at 12 weeks in genotype 1a, 1b, 2, 3a, 3b and 6 were 100%, 100%, 100%, 95%, 76% and 99%, respectively. Limited data showed that the SVR rate of sofosbuvir/velpatasvir at 12 weeks was 96% in Chinese genotype 3b patients without cirrhosis and 50% in patients with cirrhosis. After standard antiviral therapy for hepatitis C, there are still some patients who cannot obtain SVR, and these patients are defined as DAA-experienced patients. The guidelines recommend that Sofosbuvir/Velpatasvir combined with ribavirin be used as salvage therapy for patients with DAA-experienced failure. Vosevi is a new generation of antiviral therapy for hepatitis C, which contains three components, (Sofosbuvir, Velpatasvir and Voxilaprevir. It was a salvage treatment plan for DAAs-experienced patients which was recommended by the Chinese hepatitis C prevention and treatment guidelines in 2019. However, there are insufficient data on the proportion of SVR acquired in Vosevi treated DAAs-experienced patients in Asian populations and the effectivity of antiviral therapy between Vosevi and Sofosbuvir/Velpatasvir combined with ribavirin. In the present study, the investigators enroll DAAs-experienced hepatitis C patients. The participants are randomly divided into two groups. Then the participants are treated with Vosevi or Sofosbuvir/Velpatasvir combined with ribavirin respectively. All enrolled participants are followed-up for 3 years. Objectives of the present study are as follows: A. To clarify the sustained virologic response rate after Vosevi therapy for DAAs-experienced patients. B. To clarify the safety and efficacy between the Vosevi therapy and the Sofosbuvir/Velpatasvir combined with ribavirin therapy. C. To clarify the changes of biochemistry indexes in DAAs-experienced patients after Vosevi therapy. D. To clarify the virological relapse rate at 12 weeks after Vosevi therapy. E. To clarify the rate of cirrhosis and liver cancer during the follow-up.
The Partner Navigation Intervention Study is a randomized controlled study (RCT) to assess the efficacy and mechanism of action of the first behavioral intervention to increase hepatitis C (HCV) treatment initiation among adult people who inject drugs (PWID).
Prospective, cross-sectional, adaptative study to evaluate the clinical performance of the In-Vitro Diagnostics Medical Device MagIA IBC (a Multiplex Point-of-Care Test for the detection of HIV, HBV and HCV) in detecting anti-HIV antibodies (HIV-Ab), anti-HCV antibodies (HCV-Ab), and HBs antigens (HBs-Ag) in serum, plasma, venous blood and capillary blood. If not prescribed for the patient care, blood drawings, and finger pricks will be performed on the patient for the purpose of the clinical study. The Study includes a Technical Adjustment Phase (to identify optimized acquisition parameters and to define the decision threshold for the diagnostic) followed by a Validation Phase (to validate the concordance between the matrices and to evaluate the Specificity and the Sensibility of the diagnostics)
This is a retrospective, non-interventional study. Investigators from infectious diseases and gastroenterology departments will participate this study. Patients data will be collected from hospital medical records.
The goal of this clinical trial is to evaluate the effectiveness of sofosbuvir/daclatasvir combination for children aged ≥ 6 years old and adolescents with active HCV infection in Cambodia
Reintroduction of patients into a HCV infection care pathway after a positive chronic hepatitis C diagnosis by previous testing in our hospital who were lost in follow-up. Gaining insight in the possible reasons why patients are lost in follow-up after positive hepatitis C serology.
