Active clinical trials for "Fibrosis"

to investigate the prevalence of hepatopulmonary syndrome in cirrhosis patients caused by Hepatitis B in western China

Esophageal variceal bleeding and hepatic encephalopathy are serious complications of hepatic cirrhosis, and they may lead to high mortality rate and severely threaten life quality of the patients

Malnutrition is a common figure associated with liver cirrhosis. The main component of malnutrition in liver cirrhosis is represented by sarcopenia, a condition of a progressive and generalized loss of muscle mass and strength. Many studies have reported that sarcopenia is an independent predictor of morbidity and mortality in cirrhotic patients. Moreover, cirrhotic patients may develop simultaneous loss of skeletal muscle and gain of adipose tissue, culminating in a condition of "sarcopenic obesity". As highlighted by a recent systematic review and meta-analysis [Van Vgut 2017] all the studies on the impact of sarcopenia/sarcopenic obesity and myosteatosis in cirrhotic patients are retrospective studies, mostly involving non-consecutive patients on the list for liver transplantation. Moreover, most of the studies were produced by non-European centers (Canadians,Americans, and Japanese) that published more papers on the same patient series. All these factors have led to a possible selection bias. Furthermore, the methods used to evaluate sarcopenia and myosteatosis were not homogeneous (the entire muscle area, or area of the psoas or psoas diameter) as well as the cut-offs used. For these reasons, we propose a multicentric observational prospective study aimed at analyzing the impact of sarcopenia, sarcopenic obesity and myosteatosis in cirrhotic patients not listed for liver transplantation. Primary endpoint: - Evaluation of the impact of sarcopenia on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Secondary end-point: Evaluation of the impact of sarcopenic obesity and myosteatosis on the mortality of cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the development of complications (hepatic encephalopathy, bacterial infections, ascites, GI bleeding) in cirrhotic patients not on the waiting list for liver transplantation. Evaluation of the impact of sarcopenia/sarcopenic obesity and myosteatosis on the number of admissions and the days of hospitalization for such complications. Evaluation of the subcutaneous fat impact on mortality and morbidity of cirrhotic patients not on the waiting list for liver transplantation. Concordance analysis of the various methods used (different cut-off/area psoas vs. area of all muscles) for the diagnosis of sarcopenia through the analysis of CT scan.

Investigate systemic inflammation in liver cirrhosis patients

This project is to understand the LTBP4 expression in human renal fibrotic tissues. The investigators will exam major location of LTBP4 expression and check any similar or discrepancy in renal fibrosis with different etiologies.

Individuals with hepatic cirrhosis (n=50) and healthy controls (n=30) were recruited. Sleep quality, sleep timing parameters and circadian preference were evaluated using the Pittsburgh Sleep Quality Index (PSQI), Sleep Timing Questionnaire (STQ) and The Composite Scale for Morningness (CSM) respectively

Purpose The purpose of this study is to develop and validate multimodal testing of exocrine pancreatic function (EPF). The investigators will be testing exocrine pancreatic function in patients with cystic fibrosis (CF). Exocrine pancreatic function and imaging will be correlated to age group, genotype, nutritional status and quality of life. Earlier detection of exocrine pancreatic failure in the non classical form of cystic fibrosis may be of therapeutically benefit. Hypotheses Endoscopic short test can be applied in diagnosing and monitoring exocrine pancreatic function in patients with cystic fibrosis. New functional testing of exocrine pancreatic function is superior to traditional testing with fecal elastase. MRI and ultrasound methods can give volume output estimate in cystic fibrosis patients. Contrast enhanced ultrasound can quantify reduced or delayed pancreatic perfusion and parenchymal changes in cystic fibrosis patients. Elastography/ CEUS can be used in prediction and monitoring of fibrosis development and development of hepatocellular carcinoma in the liver of cystic fibrosis patients. Immunohistochemical quantification of secretin/ cholecystokinin (CCK) producing cell in duodenum can be utilized as a model hormonal signaling in cystic fibrosis patients with exocrine pancreatic function.

Hepatocellular carcinoma (HCC) is a major public health problem, whose incidence is increasing in developed countries and is the leading cause of death in patients with cirrhosis. The diagnosis and the early management are key issues that could improve the prognosis. In France, alcoholic cirrhosis is the leading cause of HCC, while the aetiology of underlying chronic liver disease is mainly hepatitis C (HCV) in Southern Europe and Japan, and hepatitis B (HBV) in Asia and Africa. In the next years, due to the improved results of anti-viral therapies, this trend should be reinforced with a decreasing proportion of HCC related to viral cirrhosis and an increasing proportion of HCC related to alcoholic cirrhosis. However, natural history of alcoholic cirrhosis remains poorly understood, most studies being retrospective and including a small number of patients. This project is filed by the consortium CIRRAL including French Academic hospitals centers currently involved and referees in the field of alcoholic liver disease and HCC (8 at the moment, and more in the next months). It is a national multicenter prospective study that will include 1200 patients with alcoholic cirrhosis histologically proven over 3 years. The main goal of this cohort is to describe the natural history of a large number of patients with alcoholic cirrhosis prospectively followed, and to identify predictors of the occurrence of HCC.

This study looks at the iontophoresis of urotensin II in chronic liver disease patients.

The aim of this prospective study was to evaluate the applicability and diagnostic performances of Smart-Shear wave(SSW) imaging, in comparison with Transient elastography(TE) for the staging of liver fibrosis using pathologic results as the reference standard.
