Active clinical trials for "Thrombosis"

The G-NUH registry is a two-center, real-world registry of percutaneous coronary intervention in patients with significant coronary artery disease. From January 2010, PCI-treated patients from Gyeonsang National University Hospitals (Jinju & Changwon) were enrolled in this registry. The aim of this registry is to investigate long-term clinical outcomes and predictors of adverse outcomes after percutaneous coronary intervention from the academic hospitals.

Epidemiological, observational, non-interventional, multicentric study on patients diagnosed with cancer who develop a venous or arterial thromboembolic episode, symptomatic or incidental, within a month prior to cancer diagnosis or at anytime after such diagnosis

To compare IJV and SCV as the implantation site of TIVAD and its associated thrombotic or occlusion rate, our study plans to enroll 240 patients with cancer who require central line TIVADs and randomizes them with 1:1 ratio to receive the TIVAD implantation at SCV or IJV. After the implantation, the patients will be regularly followed through phone contact and chart review for 2 years, and any symptomatic thrombosis or occlusion will be found during chemotherapy injection or regular push-pull heparin saline flush every 6 weeks as our hospital care protocol. To detect any asymptomatic thrombosis, the patients will also receive screening vascular ultrasound at 2 weeks, 2 months, and 6 months postoperatively. The study primary endpoints include any infection, asymptomatic thrombosis found by screen ultrasound, and clinically symptomatic thrombosis or occlusion and major mechanical failure/dislocation of TIVAD.

In patients with symptoms of Venous Thromboembolism (VTE) (mainly deep vein thrombosis (DVT) or pulmonary embolism (PE)), the study will evaluate the agreement between the D-Dimer measurements from the LumiraDx POC D-Dimer assay and a reference method, as an aid in diagnosis, assessment and exclusion of DVT and PE.

Novel coronavirus 2019 (COVID-19) has emerged as a major international public health concern. While much of the morbidity and mortality associated with COVID-19 has been attributed to acute respiratory distress syndrome (ARDS) or end-organ failure, emerging data suggest that disorders of coagulation, in particular hypercoagulability and venous thromboembolism (VTE), may represent an additional major, and possibly preventable, complication (Wu C, et al. JAMA Intern Med. 2020 Mar 13. [Epub ahead of print] and Tang N, et al. Thromb. Haemost. 2020 Feb 19. [EPub Ahead of Print]). Abnormal coagulation testing results, especially markedly elevated D-dimer and FDP, have been associated with a poor prognosis in COVID-19 infection. We propose the following Electronic Health Record (EHR)-guided 10000-patient, retrospective observational cohort study to assess VTE incidence, risk factors, prevention and management patterns, and thrombotic outcomes in patients with COVID-19 infection. In order to gain the valuable perspective of other regional and national centers providing care for large populations of COVID-19, we have started a collaborative network with 5 additional sites which will provide us with de-identified data from 1000 patients each. These 5000 patients in addition to the 5000-patient cohort we are enrolling within the Mass General Brigham Network will comprise this study population.

A new Clinical Score (CS) to rule out Deep Vein Thrombosis (DVT) has to be derived and internally validated (with bootstrap method), from patients suspected of DVT in Italy. Primary care physicians (general practitioners) in Lombardy will be instructed to inform patients suspected of DVT about this research and get in touch with the team to get details and, eventually, volunteer for the study. The CS includes categorical variables and a continuous variable: the differential leg skin temperature measured with a low-cost handheld infrared thermometer in object surface mode.

In the context of anti-Covid19 vaccination, atypical thrombosis have occured and potential link with vaccination is under investigation. This study collect clinical and biological data of all atypical thrombosis occurring within 4 weeks after antiCovid vaccination.

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.

Beyond the first 6 months of anticoagulation, patients with a first episode of unprovoked venous thromboembolism have a high risk of recurrence after stopping anticoagulations. Extending anticoagulant therapy for an additional 18 months is associated with a major reduction of recurrent VTE; however this benefit tended to be lost after stopping anticoagulation during a follow-up period of two years. This risk of recurrentce is likely to continuously increase over the years as well as the risk of chronic thromboembolic pulmonary hypertension (after pulmonary embolism) or the risk of post-thrombotic syndrome (after deep vein thrombosis). The aim of the PADIS-EXTENSION trial is to estimate these risks over 6 years of follow-up in patients who have been initially treated during 6 months or 24 months (patients included in the PADIS PE and PADIS DVT trial).

This project addresses the role of lab markers around the time of central line placement in predicting risk of thrombosis in pediatric patients with central venous lines being placed. The project proposes an innovative way to predict higher risk of thrombosis in the pediatric population to give clinicians a valid tool to guide clinical practice for these patients.
