Filter by:The purpose of this study is to investigate the safety and tolerability of PRI-724 in patients with HCV-induced cirrhosis.
Chronic liver disease/fibrosis can be the result of various causes, and the result is that the liver tissue becomes stiff. ShearWave™ elastography, available on the Aixplorer® ultrasound system, is a method that can be used to measure the stiffness of organs in the body, for example the liver. This study will evaluate how this technology performs as a non-invasive test to stage liver fibrosis in patients with chronic liver disease.
The development of ascites in the natural history of cirrhosis heralds a worsening of the prognosis to 50% survival at 2 years, and this deteriorates to 30-50% at 1 year when the ascites becomes refractory to medical therapy. Hemodynamic alterations and their relation to neurohumoral systems are essential in pathophysiology of ascites formation. The theory that best explain the ascites formation and sodium retention in cirrhotics is portal hypertension leading to splanchnic arterial vasodilatation leading to underfilling of arterial circulation which is sensed by the arterial and the cardiopulmonary receptors leading to sympathetic nervous system activation and activation of the anti-natriuretic factors (RAAS and arginine vasopressin), resulting in sodium and water retention. The therapeutic options available for patients with refractory ascites are serial therapeutic paracentesis, liver transplantation and transjugular intrahepatic portosystemic shunts.Vasopressin V2 receptor antagonists antagonize the antidiuretic effects of vasopressin at the V2 receptor located in the renal collecting duct, they increase free water clearance, and thus may be helpful in mobilizing excess water in conditions associated with water retention including cirrhosis. The use of V2 receptor antagonists in cirrhosis with ascites has been shown to be safe and efficacious. Midodrine, an alpha adreno receptor agonist by causing splanchnic vasoconstriction has been used in hepatorenal syndrome (HRS) and for control of ascites in patients with refractory or recurrent ascites. It is possible that vasoconstrictors and aquaretics (V2 receptor antagonists) by acting at different sites in combination may reverse some of the pathogenic events that results in refractory or recurrent ascites.There are no reports on the use of combination of midodrine and tolvaptan in the patients with cirrhosis with ascites. Therefore, we plan to study the role of midodrine, tolvaptan and their combination on systemic hemodynamics, renal functions and control of ascites in patients with cirrhosis and refractory or recurrent ascites.
30% of ketamine users complain of abdominal discomfort. Long-term ketamine use is associated with hepatotoxicity and pathologic changes to the biliary tract. Yet the prevalence of gastrointestinal and hepatobiliary pathologies in ketamine users has not been well-described. The investigators plan to recruit a large number of ketamine users based on referrals from different Psychiatry clusters in Hong Kong and to investigate the underlying cause of abdominal discomfort, describe the prevalence of different gastrointestinal and hepatobiliary pathologies and describe their long-term outcome.
Multicentric, observational and prospective study with two groups of treatment: Refractory ascites and non-refractory ascites. All patients should be prescribed beta-adrenergic blockers as primary or secondary profilaxis for variceal bleeding.
The purpose of this study is to determine whether transjugular intrahepatic portosystemic shunt (TIPS) combined with large spontaneous portosystemic shunts embolization are effective in the prevention of hepatic encephalopathy (HE).
The purpose of this study is to test the safety and determine the maximum safe dose of an experimental drug called LDE225 (hedgehog inhibitor) in people with liver cancer. We have identified hedgehog dysregulation as a novel mechanism for hepatocarcinogenesis and hepatic fibrosis/cirrhosis. Therefore, we hypothesize that the hedgehog inhibitor may be an ideal drug target for treating both hepatocellular carcinoma (HCC) and Child-Pugh A cirrhosis (CPA).
This study will be used to train an algorithm using Methacetin breath test (MBT) measures and to select a cut-off to determine presence or absence of Clinically Significant Portal Hypertension (CSPH) as defined by Hepatic Venous Gradient Pressure (HVPG) ≥ 10mmHg,
This is a double-blind, multicenter study involving patients with chronic HCV infection who had a liver transplantation; developed HCV-related liver fibrosis and/or incomplete cirrhosis; achieved a sustained virologic response (SVR) following anti-HCV therapy; but still have fibrosis and/or incomplete cirrhosis on liver biopsy to see if treatment with IDN-6556 is better than placebo in reversing or stopping the progression of the damage to the new liver caused by HCV.
The purpose of this study is to determine the safety, tolerability, and activity of extended treatment with NGM282 in patients with Primary Biliary Cirrhosis.
