Portal hypertension is not a disease in itself. Rather, it is an indication of an illness, caused mostly by chronic lesions of the liver because of distinct causes, such as viral infection, chronic alcoholism, or metabolic disorders. Other reasons include splanchnic vascular diseases (for example, obstruction of the portal or the hepatic veins). Portal hypertension is defined as a pressure in the portal vein exceeding the vena cava pressure by more than 5 mm Hg.
Portal pressure gradient (PPG) above 12 mmHg after transjugular intrahepatic portosystemic shunt (TIPS) increases the risk of portal hypertension complications. Currently, a PPG reduction
Investigate vasoactive medicators in portal hypertension on stored sera
The investigators will address the hypothesis that portal hypertension is mediated in part by bacterial or endotoxin translocation and the production of inflammatory mediators (tumor necrosis factor-α (TNFα), etc.). The investigators hypothesize that food supplementation with the probiotic product VSL#3 in patients with Child Pugh B/C cirrhosis will have a beneficial effect on in portal pressure (as measured by the HVPG) by reducing inflammatory mediators and improving syste...
This study is to evaluate the role of probiotics in the treatment of portal hypertension. In particular the role of probiotics on gut microbiota in liver cirrhosis patients will be studied and compared with cytokines and other substances implicated in the pathogenesis of portal hypertension. The hypothesis whether probiotics may change the prognosis of patients with portal hypertension will be studied. The hypothesis whether probiotics may halt the pathologic cascade of events ...
This study evaluates correlation in changes of HVPG-pressure values and stiffness values (ARFI) for spleen and liver and flow-volume values in Portal vein in patients with liver cirrhosis/Portal Hypertension, respectively, after new-admission of beta-blocker therapy.
Non-alcoholic fatty liver disease (NAFLD) is the most frequent cause of chronic liver disease in our environment. Preliminary data suggest that portal hypertension may exist in the initial phases of NAFLD due to mechanisms that have not yet been elucidated. The clinical relevance of its development in these initial phases is unknown, while in more advanced phases new data are required to confirm the close relationship between portal hypertension and the risk of decompensation d...
Portal hypertension is a common complication of chronic liver diseases and is responsible for most clinical consequences of cirrhosis. measurement of the hepatic venous pressure gradient(HVPG) is the gold standard for evaluating the presence and severity of portal hypertension, this technique is considered invasive and is not routinely performed in all centers. Wisteria floribunda agglutinin-positive human Mac-2 binding protein (WFA+-M2BP) is a secreted N-glycoprotein, which ha...
The purpose of this trial is to investigate safety, tolerability, pharmacodynamics, and pharmacokinetics after intravenous administration of FE 204205 in patients with cirrhotic portal hypertension.
Portal flow pulsatility detected by Doppler ultrasound is an echographic marker of cardiogenic portal hypertension from right ventricular failure and is associated with adverse outcomes based on previous studies performed at the Montreal Heart Institute. This multicenter prospective cohort study aims to determine if portal flow pulsatility after cardiopulmonary bypass separation is associated with a longer requirement of life support after cardiac surgery.
Endothelin is a human hormone which has been associated with increased portal pressure in patients with liver cirrhosis (also called portal hypertension). Ambrisentan blocks the effects of endothelin. The purpose of this study is to evaluate the effect of ambrisentan on portal pressure and renal function in patients with advanced liver cirrhosis and with portal hypertension. In this study, portal pressure will be determined at multiple times with the aid of a catheter inserted ...
To evaluate the values of portosystemic shunt and other interventional radiology approaches for treatment of symptomatic portal hypertension in patients with cavernous transformation of portal vein.
The purpose of this study is to determine whether new multiparametric magnetic resonance imaging (MRI) methods (including diffusion-weighted MRI, dynamic contrast-enhanced MRI, MR elastography and phase-contrast imaging) can be useful in assessing liver damage and degree of portal hypertension (a complication of advanced liver fibrosis and cirrhosis) secondary to chronic liver disease, compared to ultrasound measurement of liver stiffness [acoustic radiation force impulse (ARFI...
Chronic liver diseases are often characterized by portal hypertension, a major complication involving haemodynamic changes due to increased intrahepatic vascular resistance. It has become well established that nitric oxide (NO) plays a crucial role in the haemodynamic abnormalities that develop in chronic portal hypertension. NCX-1000 is a NO-releasing derivative of ursodeoxycholic acid that would compensate for the defective liver NO production in cirrhosis. This study...
The main purpose of this exploratory study is to investigate the effect of serelaxin (RLX030) infusion on the hepatic and renal circulation in patients with compensated cirrhosis and portal hypertension. Measurements will be acquired non-invasively using magnetic resonance angiography (MRA) (study part A) and more directly via cannulation of the hepatic portal vein during a routine transjugular intrahepatic portosystemic shunt (TIPSS) check procedure (study part B), to determin...
Portal hypertension (an increase in blood pressure in the portal vein that carries the blood from the intestine and spleen to the liver) underlies most of the serious complications of liver cirrhosis. This randomised placebo controlled study in people with liver cirrhosis evaluates the acute effects serelaxin (RLX030) infusion on portal hypertension and liver blood flow.
Intrahepatic non-cirrhotic portal hypertension (INCPH) is a rare disease mostly affecting adults in their forties, characterized by portal hypertension related to alterations of intrahepatic microcirculation in the absence of cirrhosis.The only therapeutic options currently available for patients with INCPH include prophylaxis for variceal bleeding using betablockers and/or endoscopic band ligation and TIPSS (transjugular intrahepatic portosystemic shunt) or liver transplantati...
The primary purpose of this study is to evaluate the safety and efficacy of partial splenic artery embolization in the treatment of symptomatic portal vein hypertension. A secondary aim is to evaluate the relative efficacy of two separate splenic artery embolization techniques, coiling versus particle embolization of the spleen. These two methods will be compared to standard medical management which consist of pain management and fluid draining.
To evaluate the values of transhepatic portosystemic shunt for treatment of symptomatic portal hypertension with portal vein occlusion after splenectomy.
This study compare the efficiency of partial splenic embolization +endoscopical therapy with endoscopical therapy alone in gastroesophageal variceal haemorrhage accompanied with splenomegaly or hypersplenism of hepatocirrhosis and portal hypertension treatment.
The objective of this study is to evaluate the pre-operative symptoms and medical history of patients with portal hypertension who have undergone placement of H-graft portacaval shunts and correlate this with patient outcomes.
This placebo-controlled study will assess the safety and efficacy of a 90-day course of treatment with ifetroban for portal hypertension in cirrhotic patients
Portal hypertension is a common pathology in chronic liver disease, particularly in liver cirrhosis. Hepatitis B Virus (HBV) is one of most etiologies of liver cirrhosis in China. The basic reason for portal hypertension in HBV is the largely deposition of hepatic extracellular matrixes which causes high pressure in liver vessels. One of the most common symptoms of cirrhotic portal hypertension is gastroesophageal varices.The effective inhibition of HBV can partially stop or re...
Background & Aims: Non-cirrhotic portal hypertension (NCPH) represents a relatively infrequent group of conditions. This work aimed at determining causes of NCPH and evaluating the role of some clinical, laboratory, imaging and endoscopic parameters in prediction of variceal bleeding in an Egyptian cohort with NCPH. Methods: Sixty patients with non-cirrhotic portal hypertension and oesophageal varices were included. All underwent complete clinical evaluation, laboratory invest...
The effect of portal hypertension on gastrointestinal motility, and how reversal or improvement in portal hypertension may alter gastrointestinal motility, remains unclear and further research is needed. Additionally, patients with cirrhosis have altered gut microflora, particularly rich in lactobacilli, including enterococci and bifidobacteria. Transjugular Intraheptic Portosystemic Shunting (TIPS) is a procedure performed by interventional radiologists, in which a connection ...
