NCT ID: NCT06054451 Recruiting - Portal Hypertension Clinical Trials

Clinical Diagnosis and Pathological Spectrum of Porto-sinusoidal Vascular Disease in India

PSVD-India
Start date: August 1, 2023
Phase:
Study type: Observational

There is a need to re-evaluate the patients classified as NCPH and determine whether the new histological classification proposed by the VALDIG applies to the Indian scenario. We intend to identify the patient cohorts who have been diagnosed as NCPH, NCPF, EHPVO, hepatic venous outlet tract obstruction (HVOTO), Veno-occlusive disease (VOD) and sinusoidal obstruction syndrome (SOS) based on their liver biopsy, endoscopy, HVPG, and radiology reports. These patients will be screened to find the patients who fit the diagnosis of PSVD. It is important to establish whether the new definition of PSVD is relevant to the Indian population and establish the usefulness of invasive tests like liver biopsy in diagnosing the disease. The patient cohorts meeting diagnosis of INCPH will be compared with those meeting the new diagnosis of PSVD. The investigators will describe the clinical (demographic, clinical risk factors, socioeconomic status), etiological (associated conditions, coagulation disorders medication use, genetic risk factors), imaging (based on ultrasound Doppler imaging or cross- sectional imaging), endoscopic, fibrosis tests (using non-invasive tests), and the histopathology of the patients who fulfil the criteria of PSVD.

NCT ID: NCT05123326 Recruiting - Clinical trials for Portal Vein Thrombosis

Global Coagulation Assessment in Portal Vein Thrombosis and Budd-Chiari Syndrome

Liv-Thrombus
Start date: October 15, 2021
Phase:
Study type: Observational

Portal vein thrombosis is defined as partial or complete occlusion of the portal vein lumen by the blood clot or its replacement by multiple collateral vessels with the hepato-petal flow, known as 'portal cavernoma'. [1,2] Based on the published literature, 15-25% of patients with cirrhosis have portal vein thrombosis (PVT) [3], and 35-50% of patients with hepatocellular carcinoma (HCC) have malignant PVT [4] compared to 1-3.8 per 100,000 patients in the general population. [5] The reported cumulative incidence of PVT in patients of Child-Pugh A and B is 4.6% and 10.7% at 1 and 5 years respectively with higher incidence among those with decompensated disease or with an underlying hypercoagulable disorder. [6]. Similarly, the prevalence of PVT in compensated cirrhosis is around 1% which increases to 8 - 25% in liver transplant (LT) candidates and 40% in patients with hepatocellular carcinoma (HCC) [7,8]. Based on the published literature 7-9 % of all chronic liver disease patients have hepatic vein outflow tract obstruction (HVOTO) in the Indian population. [9] HVOTO is defined as obstruction to hepatic venous outflow at any site from the right atrium inlet to the small hepatic venules. The Budd-Chiari syndrome (BCS) results from occlusion of one or more hepatic veins (HV) and/or the inferior vena cava (IVC). In the West, the most common cause is HV occlusion by thrombosis. More recent Indian studies have however shown that isolated HV and combined IVC+HV obstruction are now more common. [10] In the post COVID-19 era, there has been great interest in the prothrombotic states associated with the SARS-Cov-2 virus infection, and the adverse effects of some vaccines. [11] With the availability of better molecular tests for hypercoagulable states, use of global coagulation tests (GCT) like rotational thromboelastometry (ROTEM), thromboelastography (TEG) and Sonoclot, use of therapeutic procedures like Transjugular intrahepatic portosystemic shunt (TIPS), availability of novel oral anticoagulants (NOAC), the natural course of disease can be changed with good outcomes. [12] Standard Coagulation tests (SCTs) like PT, aPTT, and platelet count are not predictive of bleeding or coagulation risk as they exclude the cellular elements of hemostasis and are unable to assess the effect of thrombomodulin and cannot assess the stage of the coagulation pathway which is affected. Global coagulation tests provide dynamic information on the coagulation pathway that is not available from conventional tests. [13]

NCT ID: NCT05117684 Completed - Clinical trials for Budd-Chiari Syndrome

To Compare "Balloon Occluded Thrombolysis" With "Conventional Catheter Directed Thrombolysis" in Thrombotically Occluded DIPSS Stent in Patients of Budd- Chiari Syndrome.

Start date: November 5, 2021
Phase:
Study type: Observational

DIPSS has become a widely accepted treatment for complications of portal hypertension. Shunt or hepatic vein stenosis are common short and mid term complications of the procedure. When identified early, shunt stenosis or occlusion may be treated before recurrence of the symptoms for which DIPSS was done at the first place. Present day endovascular DIPSS revision techniques have significantly improved the primary assisted patency rates. The purpose of this study is to understand the newer technique of Combined balloon occlusion thrombolysis and intra stent balloon sweeping being practiced at our institute and compare it with the widely used conventional thrombolytic methods.

NCT ID: NCT03541057 Recruiting - Clinical trials for Portal Vein Thrombosis

Vienna Vascular Liver Disease Study

VALID
Start date: December 12, 2017
Phase:
Study type: Observational [Patient Registry]

The aim of this Register Trial is to systematically study the epidemiology, risk factors, liver function as well prognosis of patients with vascular liver diseases. Furthermore, important clinical parameters will be assessed in order to evaluate patients' coagulation status and in order to develop new biomarkers derived from blood, urine, stool or ascites of patients as well as histological samples from the upper / lower GI-tract or the liver in order to better understand the natural history of vascular liver diseases.

NCT ID: NCT02275585 Withdrawn - Cirrhosis Clinical Trials

Phase: N/A
Study type: Observational

This study evaluates the supervivence of cirrhotic patients that develop portal vein thrombosis in comparison to cirrhotic patients that do not develop portal vein thrombosis.

NCT ID: NCT02201485 Completed - Clinical trials for Budd-Chiari Syndrome

Budd-Chiari Syndrome in China: Balloon Angioplasty Alone or Combined With Stent Placement?

Start date: May 2014
Phase: N/A
Study type: Interventional

Budd-Chiari syndrome (BCS) is defined as the hepatic outflow obstruction from the small hepatic veins to the confluence between inferior vena cava and right atrium, which often leads to the life-threatening complications, such as liver failure and portal hypertension-related complications. At present, a stepwise treatment strategy is employed, including anticoagulation, thrombolysis, percutaneous recanalization (i.e., percutaneous transluminal angioplasty [PTA] alone or in combination with stent placement), transjugular intrahepatic portosystemic shunt, and liver transplantation. In West, only less than 20% of BCS patients underwent percutaneous recanalization; by contrast, percutaneous recanalization is the most common treatment modality used in China. Recently, an 11-year retrospective case series of 177 Chinese patients with primary BCS has shown a higher rate of re-occlusion in the PTA alone group than in the PTA combined with stent placement group (31% versus 7.7%, p<0.001). In addition, re-occlusion was regarded as the independent predictor of mortality. Accordingly, we hypothesized that PTA alone might have a worse survival than PTA combined with stent placement in Chinese patients with primary BCS.

NCT ID: NCT00272948 Completed - Clinical trials for Hepatic Veno-Occlusive Disease

Pediatric Trial Investigating the Incidence & Outcome of Veno-Occlusive Disease With the Prophylactic Use of Defibrotide

VOD-DF
Start date: December 2005
Phase: Phase 2/Phase 3
Study type: Interventional

The aim of this trial is to evaluate whether the prophylactic use of Defibrotide (DF) in pediatric patients (age less than 18 years) undergoing stem cell transplantation and who are at high risk of developing hepatic Veno-occlusive Disease (VOD) will have an impact on the incidence and severity of the disease. Patients will be randomly assigned to one of two treatment arms: Those allocated to the Prophylactic Arm will receive the study drug (Defibrotide) from the day of conditioning onwards. Patients allocated to the Control Arm will receive the study drug (Defibrotide) from the day that VOD is diagnosed.
