The Impact of Venous Thromboembolism In Critically Ill Patients: A Meta-Analysis of Major Clinical outcomes
2010
Abstract Abstract 3327 Background: Critically ill patients are at high risk of developing venous thromboembolism (VTE) during their stay in the intensive care unit (ICU) because of premorbid medical and surgical conditions. The clinical consequences of Deep Vein Thrombosis (DVT) have the potential to be serious yet are frequently unrecognized in the Intensive Care Unit (ICU). In contrast to the extensive documentation on the short and long–term outcomes of patients with DVT evaluated in other clinical settings, little is known about the clinical course of this disease in the ICU setting. We hypothesized that both undetected and clinically evident VTE would affect the prognosis of critically…
COVID-19 Vaccine and Death: Causality Algorithm According to the WHO Eligibility Diagnosis
2021
The current challenge worldwide is the administration of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines. Even if rarely, severe vascular adverse reactions temporally related to vaccine administration have induced diffidence in the population at large. In particular, researchers worldwide are focusing on the so-called “thrombosis and thrombocytopenia after COVID-19 vaccination”. This study aims to establish a practical workflow to define the relationship between adverse events following immunization (AEFI) and COVID-19 vaccination, following the basic framework of the World Health Organization (WHO). Post-mortem investigation plays a pivotal role to support this c…
Fundamental Research in Oncology and Thrombosis 2 (FRONTLINE 2): A Follow‐Up Survey
2020
Abstract Background Fundamental Research in Oncology and Thrombosis (FRONTLINE) is a global survey of physicians' perceptions and practice in the management of venous thromboembolism (VTE) in patients with cancer. Materials and Methods The present survey, FRONTLINE 2, follows the original FRONTLINE survey (published in The Oncologist in 2003) and provides insights into how physicians perceive risk of VTE in cancer and approach its prophylaxis and treatment. Results Between November 2015 and February 2016, 5,233 respondents participated, representing cancer physicians and surgeons. Most believed that less than one in five patients with any cancer might be at risk of VTE, with a slightly high…
How Epidemiology of Polycythemia Vera Has Changed in the Last 10 Years: Results From the Whole Prospective Cohort of Patients in Cyto-PV Trial As Com…
2012
Abstract Abstract 1748 Introduction: Polycythemia vera (PV) is a chronic myeloproliferative neoplasms characterized by erythrocytosis, vasomotor disturbances, pruritus, risk of disease progression into acute myeloid leukemia or myelofibrosis and cardiovascular events, the last representing the main cause of morbidity and mortality. Since 2005 the V617F point mutation in Janus Kinase 2 (JAK2) gene gained a dominant role in determining the molecular basis and the diagnosis of PV. We compared the clinical epidemiology of the 1638 patients included in the ECLAP trial in the years 1997 to 2001, with that of a “modern” cohort of 365 PV, JAK2-positive patients included in the Italian CYTO-PV rando…
Recurrent venous thromboembolism complicated by heparin-induced thrombocytopenia as a first manifestation of an occult cancer: a case report.
2008
Heparin-Induced Trombocytopenia (HIT) is a serious and potentially fatal complication of patients on heparins. Its management is difficult and it can be more complicated in patients with cancer because of the hemorrhagic risk carried out by direct inhibitor of thrombin, the currently approved drug for HIT. At present, it is not clear whether cancer patients also have an increased risk of HIT. We describe the case of a patient with occult cancer at the moment of the index venous thrombosis, who developed Deep Vein Thrombosis (DVT) and concomitant HIT with thrombotic complications (recurrent contralateral venous thrombosis). The management of HIT was efficaciously based on the combined use o…
Impact of cancer on the effectiveness of cardiac Troponin I to predict right ventricular dysfunction in acute pulmonary embolism
2015
Background Deep vein thrombosis (DVT) and pulmonary embolism (PE) are connected with a poor outcome in cancer patients. We aimed to investigate the impact of cancer on the effectiveness of cardiac Troponin I (cTnI) to predict right ventricular dysfunction (RVD) in acute PE. Methods We retrospectively analyzed the data of 182 patients with confirmed PE. PE patients were subdivided into two groups: (i) with concomitant active cancer disease or history of cancer, and (ii) without known cancer. Receiver operating characteristic (ROC) curves with area under the curve (AUC) was calculated for cTnI predicting RVD and related cut-off levels for both groups. Results Thirty-seven PE patients (20.3%) …
Inherited Thrombophilic Risk Factors and Venous Thromboembolism
2000
Study objectives To investigate whether the FIIA20210 mutation is associated with isolated pulmonaryembolism (PE). Design Case-control study. Setting Five thrombosis centers in southern Italy. Patients Six hundred forty-seven consecutive referredpatients with objectively documented venous thrombosis and 1,329control subjects. Measurements and results Medicalhistories were collected. The G-to-A transition at nucleotide 1691within the factor V gene (FV Leiden) and the G-to-A transition atnucleotide position 20210 within the prothrombin gene locus (FIIA20210), levels of anticoagulant factors, and levelsof antiphospholipid antibodies were determined by standard techniques.Patients with deep ven…
The impact of deep vein thrombosis in critically ill patients: a meta-analysis of major clinical outcomes
2015
Background. Critically ill patients appear to be at high risk of developing deep vein thrombosis (DVT) and pulmonary embolism during their stay in the intensive care unit (ICU). However, little is known about the clinical course of venous thromboembolism in the ICU setting. We therefore evaluated, through a systematic review of the literature, the available data on the impact of a diagnosis of DVT on hospital and ICU stay, duration of mechanical ventilation and mortality in critically ill patients. We also tried to determine whether currently adopted prophylactic measures need to be revised and improved in the ICU setting. Materials and methods. MEDLINE and EMBASE databases were searched up…
Activación plaquetaria e hipercolesterolemia en la patogenia de la trombosis venosa profunda
2006
Currently it is accepted that deep vein thrombosis is a multifactorial event in which the presence of activated platelets and also plasmatic lipids seems to play a pivotal role that it is not well established in the scientific bibliography. Due to the non consensus state about these topics between the different groups working in these aspects, the topic involving deep vein thrombosis-platelets-lipids, and also their interactions, still is an interesting area of investigation, in which it is necessary to carry out studies with the aim of establishing risk factors, initial diagnostic methods and clinical assays to probe the efficacy of new therapies.
Oral Dabigatran Etexilate Versus Enoxaparin for Prevention of Venous Thromboembolism After Total Hip or Knee Arthroplasty: A Pooled Analysis of Four …
2011
Abstract Abstract 2312 Introduction: Thromboprophylaxis after major orthopaedic surgery reduces the risk of venous thromboembolism (VTE). Four randomized, double-blind, non-inferiority trials compared oral dabigatran etexilate doses of 220 mg or 150 mg once daily (qd) with subcutaneous enoxaparin for the primary prevention of VTE in patients undergoing elective total hip or knee arthroplasty. In the hip arthroplasty trials (RE-NOVATE® and RE-NOVATE® II) the treatment duration was 28–35 days; in the knee arthroplasty trials it was 6–10 days (RE-MODEL™) and 12–15 days (RE-MOBILIZE®). Three of the trials used a comparator enoxaparin regimen of 40 mg qd started the evening before surgery, while…
