INTRODUCTION: In patients with a hypercoagulable state, such as patients with pulmonary embolism and/or Budd-Chiari syndrome, the complications from multiple gene mutations are more numerous than those from a single mutation. The authors present a woman with no major prior medical history who presented with pulmonary embolism and Budd-Chiari syndrome; this enigmatic co-occurrence has never been solely reported without underlying aetiology in a patient without prior medical conditions...

Background: Diabetes mellitus is a very rampant metabolic disorder, particularly type II. It has many complications such as the septic foot. Diabetic septic foot (DSF) patients are at high risk for coagulation abnormalities as well as surgical hazards. Owing to the potential sequelae of coagulation and vascular abnormalities, this work aimed at studying the hemostatic state and platelet indices in diabetes type II patients with septic foot. Methods: A case-control study was conducted during the period from July to September 2017 at Dr...

Left ventricular assist device (LVAD) pump thrombosis occurs in up to 8.4% of patients within 3-months postimplantation. Thromboelastography (TEG) could be used to signal hypercoagulability at LVAD implantation to predict patients at high risk for thrombosis. We sought to evaluate whether TEG maximum amplitude (MA) hypercoagulability (MA ≥69 mm) at the time of LVAD implantation predicts pump thrombosis. A single center, retrospective, nested case-control study was conducted using patients from January 1, 2005, to March 31, 2015...

The incidence of venous thromboembolism (VTE) in adult patients with sickle cell disease (SCD) is high. However, overlapping features between the clinical presentation of VTE and SCD complications and a low index of suspicion for thrombosis can influence patient management decisions. VTE in SCD can therefore present management challenges to the clinical hematologist. Herein, we present three distinct clinical vignettes that are representative of our clinical practice with SCD patients. These vignettes are discussed with specific reference to the hypercoagulable state in SCD patients, recent VTE diagnosis and anticoagulant therapy guidelines from the general population, and evaluation of the risk of bleeding as a result of long term exposure to anticoagulant therapy...

INTRODUCTION: TEG provides an in-vivo assessment of viscoelastic clot strength in whole blood compared with CCT, which may not reflect the influence of platelets. The aim of this study was to compare TEG vs. CCT in trauma patients stratified by mechanism of injury (MOI) and pre-existing coagulation status. METHODS: A retrospective, observational study of 230 polytrauma patients admitted to a University Hospital Level 1 Trauma Center, with TEG and CCT on admission stratified by MOI: multiple trauma (MT), isolated traumatic brain injury (TBI) or MT+TBI...

The condition sometimes referred to as "economy class syndrome," and also known as "traveler's thrombosis," is a distinctive pathological condition characterized by occurrence of venous thromboembolism (VTE) in a patient who has recently experienced a long journey (i.e., ≥ 4 h). Typically, the identified travel is by airplane, but travel with other vehicles, such as trains, trucks, buses, or cars, could potentially qualify as contributing to VTE events. Although the enhanced risk of VTE after long haul flights is now widely acknowledged, albeit potentially overhyped, the risk of venous thrombosis after prolonged travel by other modes of transport, in particular, by cars, is less well appreciated...

Hemostasis is a complex dynamic process involving bleeding and thrombosis as two end-points. Conventional coagulation tests which are measured in plasma examine only isolated portions of the coagulation cascade, thereby giving no information on important interactions essential to the clinical evaluation of hemostatic function. Thromboelastography (TEG), originally described in 1948 has improved over the decades and become a valuable tool of coagulation testing because of the limitations of standard coagulation tests...

INTRODUCTION: Recent studies have shown increased RBC aggregation and no difference in plasma viscosity in the presence of markedly lower hematocrit in women at term compared to non-pregnant women. Little is known about the outcome of blood rheological parameters and red blood cell (RBC) deformability particularly in the course of normal pregnancy. METHODS: During a 36 months interval 1.913 blood samples were randomly collected from a total of 945 pregnant women in the course of their pregnancy (n = 1...

The antiphospholipid antibody syndrome (APS) is defined by a state of hypercoagulability secondary to an autoimmune disorder. There are evidences that approximately 2.8-5.5% of cases of acute myocardial infarction (AMI) in young individuals are secondary to APS. In this case report, three coronary artery thromboses occurring within a short period are described. Initially, there was an ST-segment elevation (STEMI) in the presence of coronary artery disease (CAD), with the vessel being treated with stent implantation...

BACKGROUND: In dogs, the effects of immunosuppressive medications on hemostasis are not well known. HYPOTHESIS/OBJECTIVES: The objective was to determine the effects of immunosuppressive medications on primary and secondary hemostasis. Our hypothesis was that cyclosporine and prednisone would increase markers of hypercoagulability and thromboxane synthesis, while azathioprine, mycophenolate mofetil, and leflunomide would have minimal effects on hemostasis. ANIMALS: Eight healthy dogs...

Extracellular vesicles (EVs) act as transporters that carry regulatory molecules between cells in physiologic and pathologic states; therefore, they play a crucial role in thrombosis, inflammation, angiogenesis, vascular dysfunction and other processes that affect the course of hematologic diseases. Within the tumor microenvironment, for example the leukemic bone marrow, EVs-mediated signaling may direct the activities of surrounding cells and act as a positive feedback loop that contributes to cancer progression...

Background: Dengue fever is an important tropical infection causing significant mortality. The pathophysiology of hematological abnormalities in dengue remains poorly studied. In this study, we analyzed the hematological abnormalities by thromboelastography (TEG). Methods: This cross-sectional study evaluated complicated dengue patients with TEG. Thromboelastographic variables were categorized into six patterns: factor deficiency, platelet dysfunction, enzymatic hypercoagulability, combined enzymatic and platelet hypercoagulability, primary fibrinolysis, and secondary hyperfibrinolysis...

BACKGROUND AND AIMS: The long-term impact of sustained virological response (SVR) after direct-acting antivirals (DAAs) on the hypercoagulability associated with HCV cirrhosis is unknown. We longitudinally evaluated the effect of DAAs treatment on cirrhotic coagulopathy. METHODS: Pro- and anticoagulant factors levels and thrombin generation were assessed in patients with HCV-related cirrhosis at baseline, end of therapy (EOT), at 12, 24 and 48 weeks (W) after EOT...

Although cancer is associated with coagulation disorders, it is still unclear how the combination of tumour cell and host factors enhance the hypercoagulable state of cancer patients. Emerging evidence points to a central role for tumour endosomal and plasma-membrane derived vesicular components in the pathogenesis of cancer-related thrombosis. In particular, tumour cell membranes and extracellular vesicles (EV) harbour lipids and proteinaceous coagulation factors able to initiate multiple points within the coagulation matrix...

The higher incidence of arterial and venous events is well established in patients with rheumatoid arthritis (RA). Our aim here was to investigate whether there is a prothrombotic state in RA patients by using rotational thromboelastometry (ROTEM) method and to demonstrate whether the disease variables play a role in this process. A total of 85 patients who met the 2010 RA classification criteria were consecutively included in the study. The patients with RA who have been using antiaggregant, anticoagulant, or nonsteroidal anti-inflammatory drugs (NSAIDs) and had a history of arterial or venous thromboembolism were excluded from the study...

Patients with bladder cancer are at high risk of developing both venous and arterial thromboembolic events. Factors that contribute to this phenomenon include the hypercoagulable state induced by the malignancy itself, medical comorbidities that are common in this predominantly elderly patient population as well as treatments such as prolonged pelvic surgery and cisplatin-based chemotherapy. While formal guidelines address prevention of venous thromboembolism in patients undergoing radical cystectomy, consensus regarding the role of pharmacologic prophylaxis in patients with bladder cancer being treated with chemotherapy, either with neoadjuvant or adjuvant intent in conjunction with radical cystectomy, as part of bladder preservation protocols or for metastatic disease, has proved elusive...

Exercise is protective against cardiovascular disease, but can also provoke sudden cardiac death, a phenomenon referred to as "the exercise paradox." Extreme exertion is known to induce a rebalanced hemostatic state by causing hypercoagulability and concomitantly enhanced fibrinolysis. Over the past decade, novel techniques for quantifying hemostasis have been introduced, which may provide new insights into this process. This review summarizes recent literature on the effect of extreme exertion of both short and long duration on coagulation, fibrinolysis, and recovery of hemostatic balance...

BACKGROUND: Heparin-induced thrombocytopenia (HIT) is an adverse reaction to heparin characterized by thrombocytopenia and thrombotic complications. HIT is caused by pathogenic antibodies that bind to complexes of platelet factor 4 and heparin (PF4/heparin) leading to platelet activation and inducing a hypercoagulable state. Previous studies have shown immunity to PF4/heparin occurs early in life even before heparin exposure; however, the immunogenesis of HIT is not well characterized...
