Active clinical trials for "Liver Cirrhosis"

The purpose of this study is to investigate clinical feasibility of annual non-contrast magnetic resonance imaging for surveillance of hepatocellular carcinoma in high-risk group, in comparison with biannual ultrasonography.

This is a prospective observational study which will recruit up to 100 paediatric participants over a period of 30 months to determine whether MRI is as accurate at detecting, distinguishing, and monitoring liver disease as current standard of care techniques such as liver biopsy and fibroscan.

This study is being conducted to develop new techniques for early diagnosis of liver disease. These techniques are: Shearwave Elastography (SWE) ultrasound and blood biomarkers. SWE ultrasound uses high-frequency sound waves to view soft tissues such as muscles and internal organs and measure stiffness. An ultrasound creates computer images that show internal body organs, such as the liver or kidneys, more clearly than regular x-ray images. Biomarkers are biological molecules found in the blood that provide important information about liver disease.

Liver cirrhosis is an advanced stage of chronic liver diseases, which is often associated with various complications, namely esophageal and/or gastric varices, ascites, hepatocellular carcinoma (HCC). It is well known that the risk of complications varies even among cirrhotic patients, as those with more advanced disease would have more complications and poorer survival rates. Liver stiffness measurement (LSM) with transient elastography is found useful to identify cirrhotic patients with higher risk of portal hypertension and presence of varices . Recently, spleen stiffness measurement (SSM) with the same machine was found accurate to predict portal hypertension and esophageal varices. Investigators hypothesized that a new screening strategy guided by LSM and SSM (LSSM) values (LSSM-guided) is non-inferior to conventional strategy in terms of detection rate of clinically significant esophageal and/or gastric varices for patients with liver cirrhosis in an open-labeled randomized controlled trial. Consecutive patients with compensated liver cirrhosis will be invited for the study. Patients fulfilling the study criteria will be randomized into LSSM arm (upper endoscopy only performed to patients with high LSM or SSM values), and control arm (upper endoscopy performed to all patients). Patients randomized into LSSM arm will undergo transient elastography examination; those with high LSM or SSM results will be referred for upper endoscopy examination for to screen varices. Patients randomized into control arm will be directly referred for upper endoscopy examination.

Despite the importance of nutritional status in patient's outcome, there is no gold standard for nutritional assessment. Traditional techniques used in healthy subjects to assess nutritional status cannot be used in cirrhotic patients due especially to ascites and peripheral edema, and altered rates of biochemical markers due to liver failure. Bioelectrical impedance vector analysis has emerged as a useful method to assess body composition and nutritional status especially in patients at the extremes of body weight (fluid overload, excess of adipose tissue, etc.). With previous results from our research group, BIVA showed to be useful for evaluating cirrhotic patients. The aim of this study is to validate our previous results and validate BIVA for nutritional assessment in patients with liver cirrhosis

When someone has hepatitis C or some other condition that causes liver injury, he or she can develop a condition called liver fibrosis that over time, can cause the liver to stop working normally. Currently, the best way to determine the degree of fibrosis is to do a liver biopsy. The investigators hope to show that measuring the degree of liver fibrosis using an MRI with gadoxetate disodium is as good as or better than obtaining this information by performing a liver biopsy. Gadoxetate disodium is a contrast solution given through the veins that is considered safe, is approved for use by the Food and Drug Administration, and is already routinely given to patients with various forms of liver disease, including fibrosis.

PBC is a rare, autoimmune, cholestatic liver disease with genetic and environmental pathogenetic factors. Data about epidemiology of PBC in Switzerland are completely lacking. Epidemiology can be a powerful tool in yielding important clues as to burden and etiology of diseases. In addition, the investigators study will be the first one carried out in the country on PBC, and therefore will raise disease awareness and create a network.

Background: - Hepatitis C infection (HCV) is a leading cause of liver disease. Normal bacteria from the intestines may spread to the liver and blood during liver disease. This is called bacterial translocation (BT). Researchers think BT may cause liver disease to worsen. Objectives: - To study the mechanisms involved in BT in early and advanced liver disease. To find out whether BT causes liver disease to worsen. Eligibility: - People over age 18 with HCV and clinically stable liver disease. Design: Participants will be screened with medical history and physical exam. They will have blood tests and imaging studies. Participants will have 2 outpatient visits and a 3-day stay at the clinic. At visit 1, participants will have urine and blood tests. They will have a magnetic resonance imaging (MRI) scan. A solution will be injected into a vein. The MRI scanner is a metal cylinder surrounded by a magnetic field. The participant will lie on a table that slides in and out of the cylinder. At visit 2, a substance will be injected into a vein and swallowed. Participants will then have blood drawn 5 times over 90 minutes. During the inpatient stay, serial blood tests will be drawn. Participants will give 2 stool samples and have another MRI. A needle will be inserted through the chest wall into a vein inside the liver, guided by ultrasound. The blood pressure inside this vein will be measured and blood will be drawn from it. About 1 inch of liver tissue will be removed. A study investigator will call participants to discuss all test results.

This is a prospective cohort Study for evaluation of liver fibrosis staging with acoustic radiation force impulse elastography in patients with chronic liver disease and healthy liver/kidney donors.

This study will involve 70 patients who attend the Alfred Hospital with acute or chronic heart failure as well as 30 age and gender matched control subjects. All participants will have their history taking and a physical examination to detect symptoms and signs of heart failure. The main objectives are for determining the benefit and usefulness of Fibroscan (Liver scan) in detecting liver stiffness (a condition caused by excess fluid build up in the liver which has a negative impact on the livers ability to function properly) in heart failure patients and for characterizing the incidence and severity of liver stiffness in this group of patients. After informed consent, a blood sample will be taken from all patients to assess their full blood examination, glucose, lipid profiles, renal function and so on. Then 24-48 hours after enrollment, the liver doctors will do the liver scan (Fibroscan) by transient elastography. All the data are recorded and further analysis will be assessed. In a small group of acute patients the blood tests and liver scan will be repeated just prior to their discharge. Optional Sub-study: For participants who consent to the optional sub-study another 20 ml of blood for serum liver fibrotic markers will be collected.
