GastrOesophageal Varices After Sustained Virological Response

Chronic hepatitis C remains a public health issue because up to 70 million people are chronically infected by hepatitis C virus (HCV) worldwide. Presence of advanced fibrosis/cirrhosis might be associated with liver-related complications, such as hepatocellular carcinoma and oesophageal varices bleeding. Oesophageal varices (OV) might be present in up to 40% of patients with liver cirrhosis have and the mortality rates from bleeding might be up to 20% per episode. Early diagnosis of advanced fibrosis/cirrhosis associated with hepatitis C treatment are key features for preventive and therapeutic measures to reduce liver-related mortality in HCV-infected patients. Liver elastography is a high accurate non-invasive test for diagnosis of advanced fibrosis/cirrhosis. Few different methods of liver elastography are currently available: transient elastography by Fibroscan and ultrasound elastography by point-shear wave (p-SWE) and 2D-shear wave (2D-SWE). Gastrointestinal endoscopy (GIE) has been considered the gold standard for screening or surveillance of esophageal varices. More recently, international guidelines have been recommending the use of non-invasive methods to indicate or avoid OV screening: Baveno VI guidelines proposed that compensated cirrhotic patients with a liver stiffness measurement (LSM) by transient elastography <20kPa and a platelet count >150,000/?L can avoid screening endoscopy. The use of direct-acting agents (DAAs) has revolutionized the treatment of chronic hepatitis C with high effectiveness shown using all-oral interferon-free regimens. HCV cure, sustained virological response (SVR), has been associated with lower rates of liver-related complications, increase in quality of life and decrease in waiting-list registrations for liver transplantation in patients with chronic hepatitis C. Preliminary studies have been reporting significant regression liver stiffness after SVR. However, it is unclear whether SVR might decrease portal hypertension leading to OV regression and a reduced risk of variceal bleeding. In addition, the use of non-invasive methods to avoid OV screening must be validated in HCV patients after SVR. The aims of this cross-sectional study with prospective inclusion of patients will be: (i) to evaluate the impact of SVR in portal hypertension in HCV patients with advanced fibrosis/liver cirrhosis treated by interferon-free regimens and (ii) to validate non-invasive methods to avoid OV screening by GIE

Eliminate Hepatitis C/EC Partnership Evaluation Protocol

The Eliminate Hepatitis C (EC) Partnership project is a multi-site, multi-year project aiming to enhance and extend hepatitis C virus (HCV) care and treatment among people who inject drugs (PWID) through nurse-led models of care in the community and the prison system. The project will implement and evaluate a health service intervention to enhance HCV response by improving health promotion, offering training and education to service providers, streamlining clinical pathways, utilising data systems and surveillance and implementing the results of ongoing research and evaluation. Health services data will be used to assess the impact of the EC nurse-led support, to enhance the clinical pathway and increase HCV testing, linkage to care and treatment uptake in community and prison settings. This will include provider and client interviews and a sentinel surveillance system (ACCESS) that will track and monitor impact indicators including HCV testing, linkage to care and treatment uptake at the service and population level. Overall, evaluation data will be used to monitor the uptake of HCV treatment in PWID, monitor the effectiveness of community- and prison-based treatment program and assess the cost and feasibility of treating >1160 PWID in community-/prison-based program and assess changes in HCV prevalence in Victoria and modelling the impact of treating PWID to inform HCV elimination models in Australia and globally.

Start: December 2016
