Prophylaxis of Venous Thromboembolism in Advanced Lung Cancer (PROVE)

Prospective randomized open multicenter trial with blinded adjudication of endpoints to assess the efficacy of six-month low-dose LMWH (Low Molecular Weight Heparin) for the prevention of symptomatic or incidental VTE in patients with stage IV lung cancer and elevated D-dimer.

Start: September 2018

Role of Statin in Venous Dysfunction in Patients With Venous Thromboembolism Event

Participants between the ages of 19 and 70 who were initially diagnosed with venous thromboembolism and were accompanied by dyslipidemia (LDL> = 100 mg / dl) were enrolled. Participants diagnosed with pulmonary embolism, pulmonary embolism CT, and peripheral B-mode ultrasound (B-mode ultrasound) Only participants who do not meet the exclusion criteria should be enrolled in the study. Once the participant is selected, the patient is informed of the study and receives the consent form. Participants who are eligible for all of the criteria and who do not qualify as exclusion criteria should be enrolled in the study and randomly enrolled in a 1: 1 dose of rosuvastatin 20 mg once daily or equivalent. Participants who previously used statins have a wash-out period of two weeks or more Participants undergo a visit at 12 weeks after initiation of treatment. For fasting blood tests, patients visit on an empty stomach. Outpatient follow-up observes side effects after last visit and observes changes in vital signs and weight. After 24 weeks of treatment, the participant visits for efficacy evaluation. We performed body weight, vital signs and blood tests (WBC, hemoglobin, BUN, creatinine, CRP, D-dimer, fibrinogen, PAI-1, AST, ALT, CK, total cholesterol, triglyceride, HDL and LDL). Primary evaluation item: Improvement of venous insufficiency at 6 months Secondary evaluation items: Improvement of blood lipid concentration, inflammation and blood clotting at 6 months Comparison of numerical rate of change Tertiary evaluation items: recurrence of venous thrombosis

VTE Prevention Following Total Hip and Knee Arthroplasty

Consented patients undergoing elective total hip and total knee arthroplasty will be randomized to receive either aspirin alone or aspirin and rivaroxaban for prevention of venous thromboembolism.

Start: January 2020

Institutional Registry of Thromboembolic Disease

The purpose of this study is to create an institutional registry of Thromboembolic disease through a prospective survey based on epidemiological data, risk factors, diagnosis, prognosis, treatment, monitoring and survival. The main goal is to describe the occurrence of thromboembolic disease and the characteristics of clinical presentation, evolution and predisposing factors of these episodes in the population of the Hospital Italiano de Buenos Aires.

Start: August 2006

anti10a Levels in Women Treated With LMWH in the Postpartum Period

The aim of this study is to compare between anti-10a levels in postpartum women receiving different prophylactic doses of LMWH: one group with LMWH doses adjusted by the women's weight and the second group receiving 1mg/kg to a maximum dose of 120 mg

Start: August 2020

PET Fibrin Imaging of DVT and PE

This study aims to investigate a novel positron emission tomography(PET)-probe for imaging of fresh intravascular blood clots in pulmonary embolism (PE) and deep venous thrombosis (DVT).

Start: May 2019

A Study of Dabigatran Etexilate as Primary Treatment of Malignancy Associated Venous Thromboembolism

This trial aims at determining if dabigatran is effective in the treatment of malignancy associated VTE. Tolerance and safety of dabigatran will also be assessed. This is a single armed trial of dabigatran in patients with malignancy associated VTE. The target recruitment is 99 consecutive patients with active malignancy and newly diagnosed VTE (deep vein thrombosis and/or pulmonary embolism) in Queen Mary Hospital. Tinzaparin 175 iu/kg daily will be started after the diagnosis of VTE is confirmed (duplex Doppler ultrasonography for deep vein thrombosis, and computed tomography for pulmonary embolism), and a written consent is obtained. Patients will be switched to dabigatran 150mg twice daily from day 6 onwards. The first dose of dabigatran will be given within 2 hours before the time that the next dose of tinzaparin would have been due. Anticoagulation will be continued as long as malignancy is active. If patients achieve a complete remission of their underlying malignancies, dabigatran will be continued for 6 months further.

Identification of Novel Biomarkers to Aid in the Detection of Occult Cancer in Patients With Venous Thromboembolism

Venous thromboembolism is a common and serious complication in cancer, and is associated with a substantially increased morbidity and mortality. Furthermore, VTE may be the earliest sign of cancer. Recent studies, however, fail to show a clinical benefit of extended cancer screening in this patient population. Better risk prediction models are therefore warranted to identify VTE patients who would benefit from a rapid and extensive cancer screening. Inflammation and hypercoagulability are considered hallmarks of cancer, and emerging light is being shed on the potential of various markers of inflammation and coagulation in cancer diagnostics and prognostics. Among the inflammatory and thrombotic processes linked to cancer is the neutrophil release of web-like nuclear chromatin (DNA and histones), referred to as neutrophil extracellular traps (NETs). Driven by the tumor environment, NETs have recently been shown to play a central role in tumor progression, metastasis, and tumor-associated thrombosis. The investigators hypothesize that an enhanced inflammatory state may be predictive of an underlying cancer in patients presenting with VTE. The present study is an ongoing prospective study with the primary aim to investigate the diagnostic potential of markers of inflammation, including markers of NETs, in detecting occult cancer in patients presenting with VTE. Secondary aims are to include other biomarkers of cancer, and to assess whether any or a combination of these biomarkers may be prognostic of occult cancer, recurrent thrombotic events, mortality, or cancer disease progression in VTE patients with an underlying malignancy.

Construction and External Validation of a Predictive Clinico-biological Score of the Risk of Venous Thrombosis in Women Under Combined Oral Contraceptives

the investigators hypothesize that some of these polymorphisms contribute to VTE risk in women using COC, and that their screening could to help assess individual risk of VTE before COC prescription. In order to test this hypothesis the investigators propose to build a predictive score for VTE in women using COC based on clinical and biological factors. To this end the investigators have a large case study (including 766 patients) recruited at the "Centre d'Exploration des Pathologies Hémorragiques et Thrombotiques" (CEHT) of the laboratory of Hematology (La Timone Hospital, Marseille) between 2003 and 2013. The cases had a personal history of documented VTE while using COC (PILGRIM study). A great number of clinical and biological relevant phenotypes in the field of VTE have already been collected (including 14 polymorphisms selected on the basis of their biological plausibility and the existence association studies).To our knowledge it is the largest study specifically conducted in order to assess genetic factors associated with VTE in women using COC. These 766 cases will be compared to 766 controls from the general population (cohort Nutrinet-Santé). Then, the predictive values of the score will be assessed in an independent multicentric validation study that the investigators will set up in the field of this project. Our study should allow a better understanding of the genetic and environmental factors involved in VTE related to COC use. Besides, this project aims to respond to a major public health issue giving an effective tool for the decision of prescribing COC.
