Hepatitis C Virus Infection

The goal of this study is to determine if GPS tracking can enhance adherence to hepatitis C treatment among patients diagnosed with hepatitis C infection who are also experiencing unsheltered homelessness and receiving street medicine. Research will compare medication adherence among participants randomly assigned to receive standard medical care for Hepatitis C versus the standard medical care for Hepatitis C along with GPS tracking assistance.

Hepatitis C is a common and potentially serious disease. However, there are treatments that can cure it. That's why it's so important to detect the hepatitis C virus (HCV) and treat those affected. Today, many hepatitis C sufferers in Cameroon (and elsewhere) remain untreated. The aim of this research is therefore to evaluate a simplified screening and treatment strategy (developed specifically for the Cameroonian context) in comparison with a standard strategy (based on usual care), in order to improve access to hepatitis C treatment in Cameroon. If the results of this research are positive, this strategy could be recommended to health authorities in Cameroon and other comparable countries.

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 virus (HCV), which infects more than 185 million people, is a major risk factor. Direct-acting antiviral (DAA) therapy has significantly improved the eradication of the virus, but has not completely eliminated the risk of HCC, so careful surveillance is necessary. The genetic diversity of the natural killer receptor, histocompatibility antigens (HLA) and interferon lambda 4 (INFL4) activity, among other factors, have been found to be crucial in directing disease progression. Importantly, these markers are detectable years before the diagnosis of HCC. In addition, polymorphic variants attributable to the expression of genes involved in innate-type immune response, such as IFNL4 and HLA-E, have been shown to be predictive for the development of HCC and have not yet been extensively studied. The aim of the study is to evaluate novel circulating biomarkers, including the presence of antibodies to specific HCV proteome peptides, IFNL4 expression, and the interaction of specific HLA receptors/ligands in a large cohort of HCV-positive subjects in order to create a screening strategy for the early diagnosis of HCV-associated HCC. Part of the study will be devoted to describing the immune microenvironment associated with the expression of IFNL4 and HLAE, evaluating them as potential prognostic indicators for HCC in HCV-infected subjects undergoing surgery for HCC, as well as in those with advanced/metastatic HCC.

The aim of this study is to assess the HCV screening rate in Arizona by identification of potential HCV patients/subjects through different methods of communication - text message, email, social media, radio, newspaper ads, and flyers.

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.

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.
