Filter by: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.
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.
This is an open-label trial to evaluate safety and efficacy of treatment with BEM + RZR in subjects with chronic HCV infection.
The goal of this study is to evaluate whether the standardized liver cancer risk stratification management can effectively improve the early diagnosis rate of liver cancer in the targeted risk population in China.
To learn if giving immune checkpoint therapy (such as atezolizumab) and bevacizumab to patients who have HCC and are receiving DAAs may help to control HCC and hepatitis C.
Prolonged-Release Pirfenidone (PR-PFD) is an anti-fibrogenic and anti-inflammatory molecule used for the treatment of idiopathic pulmonary fibrosis (approved by FDA) and liver fibrosis (approved in Mexico by COFEPRIS). PFD effects are mediated in part through inhibition of TGFβ, TNFα, IL-1 and IL-6, along with NFκB activation down-regulation causing reduced TNFα and IFNγ levels. The aim of this protocol is to know if the epigenetic factors induced by PR-PFD have a regulatory role to understand the progression variants in liver fibrosis in a group of patients with viral hepatitis C, with a history of sustained viral response and advanced residual liver fibrosis. To assess the safety and efficacy of two daily doses of pirfenidone (KitosCell® LP), in patients with compensated liver cirrhosis.
Identify 300 PWUD with chronic, viremic HCV infection and engage them in a multidisciplinary, generalizable model of care and initiate HCV treatment
The investigators want to evaluate the feasibility of a decentralised hepatitis C care pathway (the Chain of Addiction Care (CAC) pathway) in several addiction care centres in the east of the Netherlands. Secondary objective: to measure the impact of hepatitis C clearance on MET (+metabolite) and BUP (+metabolite) trough levels in patients on Opioid substitution Therapy (OST). This is an exploratory, observational study.
Hepatitis C Virus (HCV) infection is an ongoing challenge in the United States, with an estimated 2.4 million individuals living with HCV in 2016. According to the Virginia Department of Health, over 11,500 people were living with HCV infection in 2017 with a rate of 170 reported cases/100,000 adults. This same year, the situation was even more dire in Roanoke City which had a rate of 524/100,000 adults. Treatment with antiviral medication is curative and well tolerated. However, gaps remain in the ability of the health system to engage the most vulnerable patients to start and complete treatment. People with HCV infection usually are unaware of the infection, which allows the disease to progress to liver damage, liver cancer and death if left untreated.At each stage of the screening, testing, and treatment process, there is significant patient loss to follow-up. Drop-off most commonly occurs between diagnosis and the first visit to a treating provider. Key barriers to successful engagement include: 1) communication issues, such as lack of phone or limited phone access; 2) lack of transportation; 3) significant social issues such as poverty; 4) substance use disorder; and 5) a limited understanding of the consequences of untreated HCV infection. In this mixed-method design, the investigators propose a pilot study that will provide education and resources, such as vouchers for phone, transportation, and meals, to the most vulnerable patients that will facilitate engagement in treatment as additional factors that may influence dropout rates are evaluated.
BACKGROUND It is estimated that around 71 milion people live with chronic hepatitis C virus (HCV) infection. This may lead to the development of liver cirrhosis and hepatocellular carcinoma (HCC). Liver cirrhosis is considered as one of the most common risk factors of hepatocellular carcinoma (HCC). HCC is seventh most common cancer worldwide. The treatment of HCV with direct-acting antivirals (DAAs) has led to the increase of sustained virological response (SVR) rates to more than 90%. It is suggested that the virus eradication reduces, but not eliminates the risk of HCC. This concerns especially patients with liver cirrhosis or previous HCC history. There are reports of early occurrence of HCC after the DAA treatment. Therefore, patients undergoing successful HCV treatment should be monitored for the possibility of hepatoccelular carcinoma occurrence. AIM OF THE STUDY In this study the investigators aimed to assess the occurrence of HCC after direct acting antiviral HCV treatment and evaluate whether the course of HCC and liver function differ among the population of patients treated with DAAs and those who were not receiving the therapy with DAA. MATERIAL AND METHODS This is the observative, cohort, retrospective study which will be performed in several clinical centres in Poland. The inclusion criteria are: hepatocellular carcinoma diagnosis, age >18 years old. The investigators will collect both epidemiological (age, gender, comorbidities, alcohol abuse) and clinical data (serum bilirubin, alanine, aspartate aminotransferase, platelets, gammaglutamyltransferase, alkaline phosphatase and alpha-fetoprotein level, Child-Pugh and MELD score, imaging tests, liver biopsy and elastography, if performed). In all patients, the HCV infection and co-infections will be assessed. In those who underwent the DAA treatment, the composition of the therapy and response to the treatment will be evaluated. Statistical analysis will be performed in subgroups of patients undergoing DAA treatment and without the therapy. The distribution of continuous variables will be analysed by the Shapiro-Wilk test. Quantitative data will be analysed using the Mann-Whitney U test or Kruskal-Wallis ANOVA when appropriate. Qualitative data will be compared using the χ² test or the Fisher exact test. Correlations between quantitative variables will be assessed using the Spearman correlation coefficient. P value will be set at <0.05.
