Filter by:Liver transplantation in children is highly successful with >80% having 20 years survival. Most pediatric liver diseases are potentially curable with liver transplantation and it is important to establish whether children who have undergone successful transplantation can expect a normal life expectancy or whether there will be a gradual decline in liver function and eventual graft loss. The most common reasons in late graft loss in children are unexplained graft inflammation ("idiopathic" post-transplant hepatitis) and graft fibrosis. PRO-C3, a disintegrin and metalloproteinase with thrombospondin motifs-generated neo-epitope marker of type III collagen formation, has been proved to be a marker of fibrosis in patients with NAFLD. The aim of this study is to explore the role of Fibrosis Panel(PRO-C3, PIIINP, TIMP-1, HA) in children received liver transplantation.
This is a double-blind, randomized, multicenter, placebo-controlled, comparative, exploratory phase II dose-finding trial. The trial will be conducted with four treatment groups in the form of a parallel group comparison and will serve to compare oral treatment with daily doses of 20, 50, or 100 mg ZED1227 vs. placebo for the treatment of patients with NAFLD with fibrosis.
It is an open label observation clinical trial, all participants are chronic liver disease. The investigators deem to make a novel evaluate criteria to hepatic fibrosis. The point of the clinical trial is to evaluate the novel biomaker 18F-FAPI-04 by PET-CT scan in the evaluation of the hepatic fibrosis.
Correlation between CMR T1-times, liver T1-times, fibroscan and fluid status to identify the correlation and pathogenesis of liver disease in patients with heart disease.
When a recurrent, long-term injury and inflammation of the liver causes an excessive accumulation of damaged tissue, a dangerous condition called liver fibrosis develops. Most chronic liver diseases eventually lead to fibrosis. Activated hepatic stellate cells (aHSC) play an important role in the development of hepatic fibrosis. Inhibiting the proliferation of stellate cells and preventing their differentiation and activation is an ideal strategy for ameliorating hepatic fibrosis. Hence imatinib have been prescribed as a promising drug to limit the progression of liver fibrosis as a clinical inhibitor of tyrosine kinase which can affect the two main pathways leading to hepatic stellate cells activation.
This study is aimed to compare the results and operating characteristics of liver stiffness measurement with the use of Fibroscan (EchoSens, France) and iLivTouch (Wuxi Hisky Medical Technologies Co., China) in patients with chronic liver diseases.
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.
Liver fibrosis is the main feature in early chronic liver diseases. If identified early, liver fibrosis is reversible. The current gold standard for diagnosing liver fibrosis is invasive liver biopsy. Existing non-invasive methods still have significant limitations. T1rho imaging is a promising non-invasive technology evaluating liver fibrosis. It does not require exogenous contrast agent or extra hardware. However, it remains challenging to perform T1rho measurements of the liver. The rich blood signal in the liver introduces quantification errors of liver parenchyma. The existing black blood MRI technologies are based on Cartesian FSE acquisitions, which are not optimal for liver imaging. The residual blood signal is often observed which confounds the measurement. Current T1rho measurement of the liver is mostly performed in two-dimension. 3D coverage of liver is desirable. However, 3D T1rho imaging of liver suffers from long scan time due to increased spatial coverage, reduced scan time efficiency from motion compensation, and high specific absorption rate (SAR). The investigators aim to overcome these challenges by developing 3D T1rho imaging technologies based on magnetization prepared spiral FSE acquisition. Compared to Cartesian FSE, Spiral FSE traverses k-space more efficiently per unit of time, and has reduced SAR due to significantly decreased number of radiofrequency pulses in the echo trains. Spiral acquisition has zero gradient moment at the kspace center, which substantially reduces its sensitivity to respiratory motion. The residual motion manifests as benign incoherent artifacts in the image domain rather than detrimental structured artifacts. Differently to Cartesian FSE, Spiral FSE provides flexibility to design and optimize flow-sensitizing gradients throughout the echo trains to achieve superior suppression of blood signal. The investigators will evaluate the proposed pulse sequences in both healthy controls and patients with liver fibrosis. This project will provide new black blood imaging technologies and a 3D diagnostic tool for early detection of liver fibrosis. This will improve clinical outcomes for patients with chronic liver disease, and provide a springboard for further development of MRI technology for other purposes.
Liver T1rho is elevated in response to accumulation of extracellular matrix proteins during fibrosis. The presence of hepatic iron overload; however, can shorten the T1rho value. With proper correction, we can remove this confounding factor and improve the reliability of T1rho for early diagnosis of liver fibrosis. Patients with early-stage liver fibrosis confirmed by biopsy will be recruited at the Prince of Wales Hospital (Hong Kong). Thirty patients and twenty healthy volunteers will be recruited. The liver iron content will be measured using the established T2* MRI relaxometry. Breathhold black blood T1rho relaxometry will be used to collect T1rho data. The measured T1rho will be retrospectively corrected to remove the shortening effect caused by iron. We will use ANOVA to compare the measurement with and without fibrosis. We will use Pearson correlations between the disease state and the imaging measurements, and ROC analysis to determine the diagnostic value of the proposed method.
