Filter by:This is a single arm prospective pilot trial that evaluates the ability of a novel imaging agent (68Ga-FAP-2286) to identify pathologic fibrosis in the setting of hepatic, cardiac and pulmonary fibrosis. FAP-2286 is a peptide that potently and selectively binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on fibroblasts and has been shown to have higher expression in idiopathic pulmonary fibrosis (IPF), cirrhosis, and cardiac fibrosis.
Chronic liver disease is a major healthcare problem in Hong Kong and worldwide. The diagnosis of liver fibrosis and inflammation in patients with chronic liver disease has important prognostic and therapeutic implications. The current gold standard to evaluate and stage the severity of liver fibrosis and inflammation is based on liver biopsies, which are invasive and impractical for screening and monitoring the disease. The existing non-invasive methods still have significant limitations to meet the challenge. Magnetic resonance effect can be used to obtain the molecular-level information on the biochemical properties of human tissues. The investigators will develop non-invasive quantitative MRI technologies to evaluate and stage liver fibrosis and inflammation. Our approaches are based on the endogenous contrast mechanism and thus do not need to inject an MRI contrast agent. Our approaches can be implemented on a regular MRI scanner and do not need any extra hardware. To enable the technology for routine clinical use, the investigators will develop fully automated post-processing techniques for the proposed MRI acquisition approaches. The investigators will perform multi-center clinical studies in Hong Kong and mainland China to validate our imaging measurements by histopathologic results from liver biopsies on patient cohorts.
This study was a randomized, double-blind, placebo-controlled, entecavir basic treatment, multicentre clinical study. The main objective of this study was to confirm the efficacy and safety of hydronidone in the treatment of chronic hepatitis B liver fibrosis.
Prospective randomized, multi-center, double blind placebo-controlled trial to assess the chemopreventive impact of atorvastatin (20 mg oral) vs placebo in up to 60 adults with advanced fibrosis at high risk of developing HCC.
Evaluate the efficacy of simvastatin in reducing liver fibrosis in patients with advanced fibrosis due to alcohol
Fontan operation is currently the most common procedure performed in patients with single-ventricle physiology. This surgery allows for passive caval blood flow to the pulmonary arteries in the absence of a subpulmonary pump and therefore separating the pulmonary circulation from systemic circulation. However, late hepatic complications such as liver fibrosis, cirrhosis, or even hepatocellular carcinoma are increasingly described in patients with Fontan circulation. The Fontan associated liver disease (FALD) is related to the decreased cardiac output and elevated central venous pressure after Fontan operation. Although the prevalence of FALD is higher than 90% in patients with Fontan circulation. There are no specific medications can reverse the liver fibrosis or prevent the progression of FALD at present. Sildenafil had been used in patients after Fontan operation not only to decrease their pulmonary vascular resistance and central venous pressure, increased systemic cardiac output. Comparing with other oral pulmonary vasodilators, sildenafil is with less possibility of liver toxicity. Therefore, we will conduct a prospective, open-labeled, randomized-controlled study in at least 90 Fontan patients with age > 12 years receiving follow -up at our institute. These patients will be in accordance with the ratio of 1: 1 distribution randomized into two groups, group 1 will receive sildenafil 20 mg three times daily for 3 years and the group will not receive any pulmonary vasodilator as a control. Patients in both group will receive the examinations of liver fibrosis markers, transient ultrasound elastography (FibroScan), diffusion-weighted magnetic resonance imaging (DW-MRI) and cardiopulmonary function test at baseline, 1 year, 2 years and 3 years after initiating treatment. Comparing the results of two groups, we may further clarify the treatment effect of sildenafil on FALD in patients after Fontan procedure.
Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide. Affecting approximately one-third of the United States (U.S.) population, the prevalence of NAFLD increases to 90% in patients with obesity. In 25% of patients, NAFLD progresses to a more severe form-non-alcoholic steatohepatitis (NASH)-which further increases the risks of cirrhosis and hepatocellular carcinoma. In 2017, the lifetime costs of caring for NASH patients in the U.S. were estimated at $222.6 billion, with the cost of caring for the advanced NASH (fibrosis stage ≥ 3) being $95.4 billion. It is projected that the number of NASH cases will increase by 63% from 2015 to 2030. Given the weight loss efficacy of Endoscopic Bariatric and Metabolic Therapies (EBMTs), it has been suggested that EBMTs may serve as a novel treatment category for NASH. Previously, the PI and Co-Is studied the effect of Intragastric balloons (IGB)-the oldest EBMT device-on NASH. EUS liver biopsy performed at the time of IGB removal revealed resolution of all NASH histologic features including fibrosis. A follow-up study by a different group showed similar findings. Furthermore, studies have showed the benefits of S-ESG and Aspiration Therapy (AT) on non-histologic features of NASH. Given the greater weight loss experienced after P-ESG compared to IGB (20% vs 10% TWL) and the more reproducible technique and shorter learning curve of the current P-ESG compared to S-ESG, we aim to assess the effect of P-ESG on NASH.
Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent condition, and when fatty liver is associated with inflammation and hepatocellular injury (steatohepatitis), it can lead to fibrosis, cirrhosis, liver failure and hepatocellular carcinoma. Liver biopsy is the gold standard for NAFLD assessment but has several drawbacks. Several drugs for NASH are now in phase 2-3 trials, and if medical treatments become available, non-invasive tools to identify patients who may benefit from a therapeutic intervention will be strongly needed. Some imaging methods have shown promising potential in fibrosis and NASH diagnosis. This study aims to evaluate the diagnostic accuracy of non-invasive imaging methods, including ultrasound (US) and Magnetic Resonance (MR) techniques, in diagnosing NASH and fibrosis in patients with or at high risk of NAFLD, using liver biopsy as the reference standard. Consecutive patients with a clinical indication for liver biopsy assessment of NAFLD are enrolled in this non-inferiority study. They undergo both a liver US and a multiparametric unenhanced liver MR examination. As reference standard, histological diagnosis of fibrosis and steatohepatitis made according to the fatty liver inhibition of progression (FLIP) algorithm is used. Sensitivity and specificity of imaging parameters alone or in different combinations will be calculated with the aim of finding one or more tests with at least 90% sensitivity/specificity compared to liver biopsy.
