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
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 primary aim of this study is to improve both physical fitness and sarcopenia of patients with ESLD who are potentially eligible for liver transplantation through a 12-week physical training program. Secondary aims will focus on changes in anthropometrics, body composition, quality of life, and metabolic profile. This is a randomized clinical trial including 50 patients, with half allocated to the active group (physical training program) and half to standard of care.
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 investigations, Color Doppler ultrasonography, platelet count/spleen diameter (mm) ratio and upper gastrointestinal endoscopy. Patients were classified into two groups according to variceal bleeding: (1) Group I: twenty six patients with history of bleeding or had an attack of bleeding during one year follow-up; and (2) Group II: thirty four patients without bleeding.
This is a prospective longitudinal study that will evaluate if changes (pre and post therapy) in indocyanine green (ICG) retention test and liver stiff ness (LS) and spleen stiffness (SS) as measured by acoustic radiofrequency impulse (ARFI) correlate with changes in portal pressure as determined by the hepatic vein pressure gradient (HVPG) in patients with compensated hepatitis C virus (HCV) cirrhosis undergoing antiviral therapy.
This is an open-label, non-randomized trial that will be conducted at two clinical sites, Thomas Jefferson University (TJU) and the Hospital of the University of Pennsylvania (HUP). Enrolled patients undergoing trans-jugular liver biopsy with hepatic vein pressure gradient (HVPG) measurements will receive a continuous infusion of Sonazoid® (GE Healthcare, Oslo, Norway) co-infused with 0.9% NaCl solution over a 5-10 minute time period. Ultrasound imaging will be performed using a Logiq 9 scanner with a 4C transducer (GE Healthcare, Milwaukee, WI) and the novel SHAPE (subharmonic aided pressure estimation) algorithm will be used to measure pressure values in the hepatic and portal veins. Data will be stored on a PC and compared to pressure-catheter measurements, Subjects identified in the initial examination as having portal hypertension (by HVPG results) will be monitored by SHAPE for up to 18 months. These subjects typically have surveillance Computed tomography (CT) or magnetic resonance imaging (MRI) scans every 6 months to screen for liver cancer, and at those times a repeat SHAPE examination will be performed (ideally within 1 month of their clinically indicated imaging follow up appointment). In patients who undergo more frequent screening (generally 3 month intervals), SHAPE exams will be performed at 6 month intervals. Any repeat trans-jugular liver biopsies performed in this population will also trigger a repeat SHAPE study. Results of blood test evaluations (performed every 3 months in this population), medication, concomitant imaging study or procedure (including endoscopies) will be noted (all blood tests and imaging are clinically indicated only and are not required by this protocol). The end point for this part of the study will be any one new complication (e.g., liver cancer) or a marked worsening in any complication, liver transplantation, death, or the end of this clinical trial (after 3 years). The investigators expect these patients will be monitored three times during the course of this clinical trial. The time to reach the end point will be noted if a new complication or a marked worsening in any complication occurs.
The aim of this study was to conduct a prospective randomized trial to compare TIPS with 8mm expanded polytetrafluoroethylene(ePTFE)-covered stents and endoscopic variceal ligation plus propranolol for the prevention of recurrent esophageal variceal bleeding.
The purpose of this study is to evaluate the effects of sustained virological response in liver and spleen stiffness in patients with HCV compensated advanced chronic liver disease treated with new all oral antiviral drugs in order to determine factors implicated in stiffness change and its implications for long-term follow-up.
The investigators want to analyze the effect of Taurin on portal hemodynamics in patients with advanced liver cirrhosis.
