Filter by: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 20 years. Despite undeniable advances in the treatment of hepatitis C infection and the WHO strategy to eliminate hepatitis C by 2030, this infection continues to be a major public health problem globally and many HCV-positive individuals are unaware of their HIV status. People who inject drugs (PWID) are at increased risk for HCV. Several studies have reported high HCV prevalence rates, especially among PWID. PWID are usually exposed to a higher risk of various infectious diseases, mainly due to their drug consumption behaviors and habits, in addition to the risks and harms associated with the respective routes of self-administration. Worldwide, there are around 11 million PWIDs and there are approximately 2.3 million coinfections between HIV and HCV worldwide, of which more than half (1.3 million) occur in PWID. The coexistence of these two health conditions leads to accelerate the progression of liver disease. The global prevalence of HCV in 2019 among PWID was 50.2%, which is equivalent to 5.6 million people who inject drugs and live with hepatitis C. PWID had been considered a difficult group to reach, manage, and treat because HCV treatment management in these individuals is challenging and they have a higher risk of reinfection and some past HCV treatment guidelines excluded PWIDs from consideration, citing concerns about adherence, increased susceptibility to side effects, and reinfection. However, there is now compelling evidence that HCV treatment is safe and effective among PWID. In Colombia, the prevalence of hepatitis C among PWID has been measured locally in some cities. In Bogotá, it went from 1.7% in 2002 to 6.7% in 2014. For 2021, the prevalence of hepatitis C was measured in Bogotá, Medellín, Santiago de Cali, the metropolitan area of Pereira, Dos Quebradas, Medellín, Cucuta, and Armenia. The results of prevalence of antibodies against hepatitis C were as follows: Cali with 80.2%, is the city with the highest reactivity, followed by Pereira and Dos Quebradas with 71.4%, Armenia with 69.6%, and Cucuta with 62.8%. We do not have recent data about the impact of intervention to reduce HVC transmission in those groups.
The project is a national, prospective, multicenter, non-interventional pilot project of screening HCV in PWID in the Czech Republic. The main goal of the project is to methodically prepare, implement and evaluate a pilot project that will verify the suitability of the proposed procedure of early detection of Hepatitis C and setting up and testing new methods and implementation into the system of social health care.
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.
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).
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.
