NCT ID: NCT05651789 Not yet recruiting - Portal Hypertension Clinical Trials

Carvedilol vs. Propranolol in Second Prophylaxis of Variceal Bleeding

Start date: January 2023
Phase: N/A
Study type: Interventional

This randomized controlled trial was conducted to evaluate the efficacy and safety of carvedilol versus propranolol, combined with routine endoscopic treatment, in the secondary prophylaxis of variceal bleeding in patients with cirrhosis.

NCT ID: NCT04957875 Completed - Portal Hypertension Clinical Trials

Timing of Endoscopy for Acute Variceal Bleeding in Patients With Cirrhosis

Start date: December 16, 2019
Phase:
Study type: Observational

Cirrhotic patients with AVB across 34 university medical centers in 30 cities in China from February 2013 to May 2020 who underwent endoscopy within 24 hours were included in this study. Patients were divided into an urgent endoscopy group (endoscopy <6h after admission) and an early endoscopy group (endoscopy 6-24h after admission). Outcomes included the incidence of 5-day rebleeding, in-hospital mortality, need for intensive care unit (ICU) and the length of hospital stay after the endoscopy management. Multivariable analysis was performed to identify risk factors for rebleeding. A propensity score matching (PSM) analysis was performed to achieve a balance at baseline between the urgent and early groups.

NCT ID: NCT04786743 Recruiting - Cirrhosis Clinical Trials

Timing of Endoscopic Intervention for Acute Variceal Hemorrhage: an RCT

TEACH
Start date: April 20, 2021
Phase: N/A
Study type: Interventional

Acute variceal upper gastrointestinal hemorrhage remains a hot potato in cirrhotic patients. The purpose of this study is to figure out whether urgent endoscopy (within 6h after gastroenterological consultation) is superior to non-urgent endoscopy (between 6h and 24h after gastroenterological consultation) in reducing re-bleeding for these patients. This is a single-centered, prospective, randomized, and controlled trial. 400 patients with suspected variceal bleeding will be randomized in a 1:1 ratio to receive endoscopic intervention either within 6h or 6-24h. Randomization is conducted by permuted block randomization stratified by age, systolic blood pressure (SBP), and pulse rate. The primary efficacy endpoint is rebleeding within 42 days after control of acute variceal bleeding. This trial will provide valuable insights into the efficacy between the urgent endoscopy group and the non-urgent endoscopy group.

NCT ID: NCT03438916 Completed - Liver Cirrhosis Clinical Trials

MRI to Assess the Effect of Non-selective Beta-blocker in Patients With Cirrhosis

Start date: April 1, 2017
Phase:
Study type: Observational

Background: Standardization and new therapeutic treatments of variceal bleeding has significantly reduced the mortality the last 25 years, but there is still a high 6-week mortality around 15-20% and 1-year mortality of about 40%. Cirrhotic patients without prophylactic treatment suffer a risk of 60% of re-bleeding within the first year after the first bleeding episode. Variceal ligation and NSBB are the standard therapy as secondary prophylaxis, while only non-selective beta-blocker (NSBB) is offered as first-line therapy in primary prophylaxis. If portal pressure is reduced to a value below 12 mmHg or by 20% (10% if assessed by intravenous administrations), the risk of bleeding is substantially reduced, but not all patients respond to the treatment with propranolol (40-50%). Hence, patients who are non-responders to NSBB should be offered alternative treatment with e.g. carvedilol, which is a combined alpha-beta-receptor blocker or endoscopic band ligation. Currently, the response to NSBB is assessed invasively during a liver vein catheterization (LVC). Unfortunately, only a few centres in the world can perform this procedure and there are no reliable non-invasive alternatives to assess the respond to NSBB, which is of extreme importance, since non-responders have three fold increased risk of a new variceal bleeding episode. Aim: In general the aim of the project is to develop faster and non-invasive methods to evaluate portal hypertension and individual pharmacological response of NSBB in patients with cirrhosis. Furthermore, we expect to detect changes in liver and spleen stiffness as measured by MR-Elastography (MRE) after NSBB and that these depend on the drug-related effects on portal pressure. Study design and patients: 39 patients with cirrhosis and esophageal varices that require NSBB (propranolol) treatment. Patients are assessed with LVC, MR-scans, echocardiography and biochemical tests. LVC is the gold standard method to test if patients respond to propranolol treatment. At visit 1. the response to NSBB is defined as a reduction of HVPG ≥10%, or to a HVPG< 12mmHg after intravenous NSBB administrations during LVC. MRI-scan with intraveneus NSBB administration is performed at visit 2. Minimum 5 days of NSBB wash out between visit 1 and 2.
