Filter by:The Researchers are trying to assess the effectiveness of a new ultrasound technique for non-invasive evaluation of liver fibrosis.
This is a pilot study to investigate the feasibility of a novel MRI technique to assess the severity of liver cirrhosis and predict complications based on functionality and perfusion measurements whilst maintaining image quality. The principal objective of this pilot study is to assess liver function and the future risk of complications in patients with cirrhosis, using novel techniques and measures based on free-breathing Dynamic Contrast Enhanced MRI. Specifically the investigators will assess: 1. Whether sufficient data can be generated in patients with cirrhosis whilst maintaining image quality, and 2. The dynamic range of DCE-MRI measures in patients with cirrhosis. This pilot study will, if successful, provide sufficient data to support applications for larger studies to evaluate the clinical utility of a DCE-MRI imaging biomarker in patients with cirrhosis.
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.
This is a prospective observational study in a single medical center. The aim is to evaluate the status of fibrosis and steatosis of liver parenchyma in peri-menopausal women using noninvasive methods of vibration-controlled transient elastography (VCTE) with controlled attenuation parameter (CAP) and serum biomarkers.

Background: With the advances in treatment and clinical care, individuals with human immunodeficiency virus (HIV) infection have experienced an increase in life expectancy. Liver disease is common among HIV-infected patients due to the shared routes of transmission of HIV and viral hepatitis. Nonalcoholic fatty liver disease (NAFLD) is the most common cause of elevated aminotransferases in HIV-monoinfected adults without HBV or HCV. Vibration-controlled transient elastography (VCTE) has been shown to have good sensitivity and specificity for assessment of liver fibrosis in HIV and viral hepatitis coinfected patients, as well as in HIV-negative NASH population. Controlled attenuation parameter (CAP), a novel physical parameter developed using the postulate that fat affects ultrasound propagation, measures the ultrasound attenuation at the center frequency of the FibroScan®. Study design: This is a prospective observational study. Objective: The aim of this study is to evaluate the liver steatosis and fibrosis in HIV-infected patients by noninvasive methods of VCTE and CAP. Methods: Patient number: 200 Inclusion criteria: 1. Age: 20-65 years 2. Males and females with HIV infection diagnosed by infection doctors 3. Willing and able to comply with the study requirements 4. Willing and able to provide written informed consent to participate in the study Exclusion criteria: 1. Pregnancy 2. Unable to complete the noninvasive procedure of VCTE and CAP 3. Unwilling to provide written informed consent to participate in the study
The purpose of this study is to determine the extent to which severe burn injuries affect the morphology and function of liver, pancreas and thyroid. The evaluation of the liver will be performed non-invasively with liver fibrosis scores based on standard blood parameters and the measurement of liver stiffness (correlated with liver fibrosis) and controlled attenuation parameter (CAP, correlated with hepatic steatosis) via transient elastography (FibroScan©, Echosens SA, Paris, France). The thyroid and the pancreas will be assessed via ultrasound (GE Medical Systems, Waukesha, USA) and standard blood parameters, respectively.
The aim of our study is to validate the non-invasive model which was constructed by our previous study for evaluating liver fibrosis or cirrhosis caused by hepatitis B virus in mainland China and to find a therapeutic regimen to reverse liver fibrosis and cirrhosis.
In this research study, the investigators will conduct a prospective cross-sectional study of pediatric and adult Fontan patients that will correlate a variety of quantitative MRI biomarkers with histopathologic data.
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.
This is a study of experimental medication BMS-986036 given to adults with Nonalcoholic Steatohepatitis (NASH; the buildup of fat and inflammation in the liver that is not caused by alcohol) and liver cirrhosis (liver damage characterized by normal liver tissue being replaced by scar tissue).
