Active clinical trials for "Hypertension, Portal"

Carvedilol has emerged as the preferred non-selective β-blocker (NSBB) for treating portal hypertension. However, there is still a debate in dosing regimen, specially regarding dose interval, with a potential lower bioavalability in once daily regimens. The aim of this study is to assess the acute effects of carvedilol posology in patients with clinically significant portal hypertension (CSPH), as a surrogate marker of bioavailability. In this experimental study, patients with CSPH receiving carvedilol twice daily were asked to supress the night dose of carvedilol, in order to have a dose interval of approximately 24 hours. Spleen stiffness measurement (SSM) by transient elastography (TE) was performed and compared with SSM prior or under treatment. Same procedure was applied to liver stiffness measurement (LSM).

How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of hepatic venous pressure gradient (HVPG) is an important general problem in the management of portal hypertension in cirrhosis. We plan to investigate the ability of AI analysis of Ultrasound, computed tomography (CT) or magnetic resonance (MR) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis.

Background: Efficacy of endoscopic variceal sclerotherapy in achieving initial control of acute variceal bleeding and five-day haemostasis has been shown to significantly improve when vasoactive drug is added. However, there is limited data whether addition of somatostatin, to endoscopic variceal ligation (EVL) improves the efficacy of EVL. Aim: To compare EVL plus somatostatin versus EVL plus placebo in control of acute variceal bleeding. Patients and methods: Consecutive cirrhotic patients with acute variceal bleeding from esophageal varices were enrolled in the trial. After emergency EVL, patients were randomized to receive either somatostatin (250 mcg/hr) or placebo infusion. Primary endpoint was treatment failure within 5 days. Treatment failure was defined as fresh hematemesis ≥2 hour after start of therapy or death.

The purpose of this study is to investigate the response to pioglitazone on the hepatic venous pressure gradient and peripheral vascular responsiveness to vasoconstrictors in patients with advanced (Child´s Grade B or C) cirrhosis.

There is no consensus about the optimal treatment of hepatocellular carcinoma (HCC) with cirrhotic portal hypertension, While this group of patients are classified as hepatectomy contraindication according to guidelines from National Comprehensive Cancer Network (NCCN) and American Association for the Study of Liver Diseases (AASLD). With improvement of surgical technique, preoperative evaluation, and perioperative management,especially the Precise Hepatectomy Technique, more and more studies confirmed the safety of surgical intervention to hepatocellular carcinoma (HCC) patients with cirrhotic portal hypertension.However, most of the previous studies were either retrospective or with small samples. The investigators project is a prospective randomized controlled trial, planning to compare the safety, efficacy and quality of life between precise hepatectomy and combined interventional treatment on hepatocellular carcinoma (HCC) with cirrhotic portal hypertension, to make a further understanding of optimal strategy.

This study is a 5 day, single-center, randomized, double blind, placebo-controlled study to evaluate the efficacy and safety of Somatostatin used as inflow modulator in liver transplantation. Patient systemic and hepatic dynamics will be collected and recorded at predefined time-points. To evaluate the ischemia-reperfusion injury, it is planned to perform liver biopsies at two different time-points to compare the liver structure and proteomic variations.

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.

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.

This study is aimed at investigating the effect of PPIs on gastroesophageal varices in liver cirrhosis. Half of participants will receive PPI, while the other half will receive a placebo.

This is a prospective, double blind controlled trial in which patients with esophagic variceal bleeding treated with standard therapy (endoscopic variceal ligation(EVL) + B-blockers), will be randomized to receive statins or placebo. They will be followed up during 12 months to determinate whether statins are effective in prevention of variceal bleeding recurrence and evaluate patient survival. Randomization will be stratified according to the degree of hepatic insufficiency, assessed by the Child-Pugh classifications (A,B or C).
