Filter by:Evaluate the feasibility of the Liver Incyte system for liver elasticity measurement in healthy volunteers and patients with liver fibrosis. To evaluate the discriminatory ability of elasticity measurements generated by Liver Incyte for healthy volunteers versus patients with liver fibrosis in comparison to FibroScan measurements.
Chronic hepatitis C infection is associated with changes of glucose metabolism end increased frequency of impaired glucose tolerance. This might be a additional risk factor for disease and fibrosis progression. The study aims to evaluate whether a therapy with direct-acting antiviral agents leading to a sustained virologic response directly impacts parameters reflecting glucose metabolism and fibrosis.
Non-Alcoholic Fatty Liver is a common clinical and histological condition associated with metabolic syndrome in patients with and without excess body weight. It represents the most common cause of liver disease in the western world and it is characterized by an excess accumulation of fatty vacuole within hepatocytes. Patients with non-alcoholic fatty liver disease (NAFLD) can progress to non-alcoholic steatohepatitis (NASH), and then into cirrhosis and its complications. The prevalence of hepatic steatosis goes from 16 to 31% in the general population, from 50 to 80% in the obese population and up to 96% in morbidly obese patients. As the majority of obese individuals have NAFLD, non-invasive and widely applicable screening tools for the assessment of liver fibrosis and steatosis are needed. The detection in early stages is the main predictive factor of the long-term outcome. Liver biopsy has traditionally been the gold standard for the assessment of patients with NAFLD, although the well-known limitations. Among the non-invasive tools available in the market, the FibroScan® (Echosens™, Paris, France) has been shown to be a useful tool for diagnosing fibrosis and steatosis in patients with suspected NAFLD. The FibroScan® is an ultrasound-based vibration-controlled transient elastography (VCTE™) device dedicated to liver stiffness measurement (LSM) and the controlled attenuation parameter (CAP). Several clinical studies have shown the benefit of measuring hepatic stiffness with the FibroScan® in overweight/moderately obese persons. The ability to identify significant fibrosis and cirrhosis has been demonstrated in normal and overweight patients affected with chronic hepatitis B and C, biliary diseases, alcohol related liver disease and NAFLD. However, subcutaneous fat attenuates the transmission of shear waves into the liver and the ultrasonic signals used to measure their speed of propagation. When scanning morbidly obese patients (BMI≥35 kg/m²) with the XL+ probe, unreliable results occur mainly due to obesity. Therefore, the XL probe has been enabled to expand the applicability of the FibroScan® but, the realization of the XL+ examination is still very difficult in the case of morbidly obese patients. This is why to reduce this failure rate, Echosens has worked on developing the XXL probe specifically for measuring the LSM in morbidly obese patients.
In the UK, around 1 in 16 men and 1 in 20 women will develop bowel cancer at some point in their lives. Most bowel cancers happen when a type of growth in the bowel called an adenoma eventually becomes cancerous. Cutting out adenomas reduces the risk of developing bowel cancer. Certain people are more likely to have adenomas than others, for example people who are overweight. People who are overweight are also more likely to develop liver disease by laying too much fat down in the liver. Studies in Asia have shown that people with fatty liver disease are more likely to have adenomas and these are more commonly found in the part of the bowel (right colon) furthest from the bottom end. Information on the link between obesity, fatty liver disease and adenomas is very limited, particularly in the Western population. The investigators will assess the link between body weight, fatty liver and adenomas in the UK population. 1430 patients will be invited; some through the bowel cancer screening programme and some with symptoms such as low blood count, bleeding or changed bowel habit. These patients will already have been referred for a camera test looking into the bowel, called a colonoscopy. Information including height, weight and some health questions will be taken. Blood samples will be taken. The investigators will compare the number of patients with adenomas who have liver disease or who are overweight with those who don't. This information will be used to develop a scoring system to predict risk of adenomas. This will help the investigators to decide if undertaking colonoscopies in these patients will identify those at increased risk of bowel cancer.
The Researchers are trying to assess the effectiveness of a new ultrasound technique for non-invasive evaluation of liver fibrosis.
Non-alcoholic fatty liver disease is the most common cause of chronic liver disease in the western world, affecting one in every three subjects. The investigators hypothesize that a patient population without known liver disease has a certain percentage of patients with liver fibrosis who are undiagnosed and not monitored.
Currently there are no guidelines for monitoring hepatic fibrosis associated with long term MTX use. Routine liver biopsies are not being done as a part of surveillance due to potential complications like bleeding and pneumothorax. Non-invasive markers like gammaglamyltransferase (GGTP), Alkaline Phosphatase (AlkPhos), Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are deranged at a late stage and may not be helpful in detecting early fibrosis. The current study will utilize a sensitive, but noninvasive, test to evaluate for hepatic fibrosis. We are attempting to screen for early detection of fibrosis due to MTX before it progresses to irreversible cirrhosis and end-stage liver disease. Based on the results of this pilot study, ultrasound elastography could be used to prospectively study a larger population to establish guidelines for monitoring safety and hepatic complications with MTX. The influence of other co-morbid factors like obesity, alcohol ingestion and smoking is critical to identifying high risk patients who may require closer monitoring. We follow close to 550 patients with IBD. If we presume that at least 20% patients are currently receiving methotrexate, we will be able to recruit enough patients for this pilot study.
