Changes in systemic redox balance can alter platelet activation and aggregation. Acute pulmonary embolism (PE) is a systematic inflammatory disease associated with mechanical shear stress, increased thrombin, catecholamines, serotonin and hemolysis, which cumulatively can hyperactivate platelets and accelerate their turnover. We tested the hypothesis that platelets from patients with moderately severe PE will show hyperstimulation and a pre-apoptotic phenotype associated with microparticles (MPs) in plasma...

In adults, the most common cause of sudden death is coronary heart disease or defects in the cardiac conduction system; however, there are many cases of sudden death occurring from other causes such as fatal pulmonary thromboembolism. Several risk factors are recognized, including hospitalization, surgery, obesity, pregnancy, the use of oral contraceptives, traumatic fractures, and genetic conditions, which cause hypercoagulable states such as factor V Leiden mutations. Although many risk factors have been identified, the mortality rate is still high...

BACKGROUND: In Zambia, 14.2% of adults have HIV/AIDS. There has been a substantial and significant increase in patients hospitalized for ischaemic stroke with co-existing HIV infection. However, little is known about the mechanism of stroke in these HIV + ve patients let alone studied in our region. The aim of this pilot study was to explore the association of hypercoagulability state in HIV + ve patients with ischaemic stroke. This was achieved by comparing hypercoagulability state markers between HIV + ve ischaemic stroke patients with HIV-ve and HIV + ve patients with and without ischaemic stroke respectively...

BACKGROUND Stroke risk and stroke recurrence are increased in cancer patients, but the pathogenesis and biomarkers of kidney cancer-related stroke (KCS) are generally unclear. The aim of the present research was to investigate the pathogenesis and plasma biomarkers of kidney cancer-related stroke. MATERIAL AND METHODS A retrospective review was conducted on acute stroke patients with kidney cancer (KC) who were admitted to the hospital between January 2006 and December 2015. A total of 106 patients with KCS (active KC patients with acute stroke but without conventional vascular risks) were identified...

Haptoglobin exerts renal protective function by scavenging free hemoglobin from the urine and blood stream in patients with hemolytic disorders. Recent studies elucidate the relationships between haptoglobin and inflammation. In addition, coagulopathy is often induced by systemic inflammation characterized by the presence of vascular endothelial damage. We hypothesize that haptoglobin might have an anti-inflammatory effect and affect hypercoagulability using rat burn model. Thirty anesthetized rats of six-weeks of age received over 30% full-thickness scald burn on the dorsal skin surface...

We report a case of cerebral venous thrombosis related to the ingestion of tadalafil. A 45-year-old man presented with posterior headache and was diagnosed with tension headache. Five days later, he was transported to our hospital via ambulance due to a tonic-clonic seizure. Head MRI showed cerebral venous thrombosis (CVT). He confessed to having recently taken a large doses of tadalafil. His anti-cardiolipin antibody and anti-caldiolipin-β2-glycoprotein-I complex antibody levels were elevated. Our case suggests the possibility that tadalafil is related to both cardiovascular complications and CVT in patients with hypercoagulability...

BACKGROUND: Paraneoplastic acral vascular syndrome (PAVS) is a rare phenomenon which is observed in patients with adenocarcinomas and other malignancies. Various potential pathogenic mechanisms such as tumour invasion of sympathetic nerves, hyperviscosity, hypercoagulability, vasoactive tumour-secreted substances, and immunological mechanisms have been suggested. CASE PRESENTATION: We report a 60-year-old Caucasian male attended our hospital with a bulky lymph node mass in the right axilla...

The hallmark manifestations of Cushing's syndrome (CS) are well known, but hypercoagulability is perhaps least recognized. Patients with CS are at increased risk of both spontaneous and postoperative thromboembolism, with the significant majority of events occurring in the lower extremity and pulmonary venous circulations. We present a case of portal vein thrombosis (PVT) occurring in the setting of newly diagnosed CS due to a left adrenal adenoma. Factor VIII activity was approximately 2.5-fold elevated, a known mechanism by which hypercortisolemia predisposes to venous thrombosis...

A man in his 30s who presented with an enlarged right testicle was diagnosed with a germ cell tumor via orchiectomy. Adjuvant chemotherapy with cisplatin, etoposide and bleomycin(BEP)was initiated. He developed a headache 8 days later, followed by neurological deficits 10 days later. Magnetic resonance imaging(MRI)and magnetic resonance venography(MRV)showed thrombotic occlusion at the superior sagittal sinus. Anticoagulant therapy with heparin was initiated. However, a generalized epileptic seizure occurred 11 days later, and an antiepileptic drug therapy was initiated...

Background: Myocardial injury after non-cardiac surgery (MINS), a complication with unclear pathogenesis, occurs within the first 30 days after surgery and worsens prognosis. Hypercoagulability induced by surgery might contribute to plaque rupture, with subsequent thrombosis and myocardial injury. This study assessed haemostatic markers before surgery and evaluated their association with MINS. Methods: This is a substudy of VISION, a prospective cohort study of perioperative cardiovascular events...

Although cancer in general is a strong risk factor for developing venous thromboembolism (VTE), the risk factors for venous thromboembolic events in patients with differentiated thyroid carcinoma (DTC) have never been assessed. This is remarkable, as several parts of the treatment comprise a hypercoagulable state that could in subgroups of DTC patients lead to an increased risk of VTE. The aim of this study was to assess which risk factors could cause DTC patients to develop VTE. We performed a nested case-control study, involving cases of DTC patients treated between 1980 and 2014 with confirmed VTE after diagnosis of DTC...

Central obesity is independently associated with an elevated risk of cardiovascular disease, particularly thrombotic complications. Increasing data supports a link between excess body weight and the risk to suffer acute myocardial infarction, stent thrombosis after percutaneous interventions, ischemic stroke and vein thrombosis.Experimental and in vitro data have provided insights as to the mechanisms currently presumed to increase the thrombotic risk in obese subjects. Obesity is characterized by a chronic low grade inflammation and systemic oxidative stress that eventually damage the endothelium losing its antithrombotic properties...

As the newer oral anticoagulants (NOACs) are increasingly used in older patients, clinical scenarios when they may need to be discontinued temporarily or indefinitely, may be encountered. Similarly with increasing use of permanent pacemakers and other intra-cardiac devices, there is an increased risk of upper limb venous thrombosis even few years after their insertion. We report a case of a patient with a permanent pacemaker, on rivaroxaban (NOAC) for atrial fibrillation, who developed an upper extremity deep vein thrombosis after its temporary withdrawal following a traumatic acute subdural haematoma...

INTRODUCTION: The increasing popularity of trekking in alpine regions has drawn attention to high altitude-associated health concerns. CASE REPORT: Here, we report a case of cerebral venous infarction as a consequence of a hypercoagulable state induced by secondary polycythemia as an adaptation to high altitude. CONCLUSIONS: When patients present focal neurological symptoms such as hemiparesis in addition to symptoms of acute mountain sickness or high-altitude cerebral edema such as headache, nausea, vomiting, and dizziness, cerebral venous infarction should be considered...

Vasospastic transient monocular vision loss associated with systemic lupus erythematosus and antiphospholipid syndrome is typically short lasting and responsive to vasodilators. Virchow's triad of endothelial dysfunction, arterial stasis, and a hypercoagulable state are factors in systemic lupus erythematosus/antiphospholipid syndrome that may potentially contribute to prolonged retinal hypoperfusion and central retinal artery occlusion. Consequently, rapid intervention to address all components of Virchow's triad may increase the probability of a good outcome...

Qiankun Zhang, Jin L V, Lie Jin
The two major theories of glucocorticoid (GC)-induced osteonecrosis of the femoral head (ONFH) are apoptosis and ischaemia. The traditional theory implicates ischaemia as the main aetiological factor because the final common pathway of ONFH is interruption of blood supply to the bone. The most common causes of interruption of blood supply include fat embolism and coagulation disorders. GCs can directly or indirectly lead to coagulation disorders, producing a hypercoagulable state, followed by poor blood flow, ischaemia, and eventually ONFH...

BACKGROUND: Although coagulopathy can be very common in severe traumatic shock patients, the exact incidence and mechanism remain unclear. In this study, a traumatic shock rabbit model with special abdomen injuries was developed and evaluated by examining indicators of clotting and fibrinolysis. METHODS: Forty New Zealand white rabbits were randomly divided into four groups: group 1 (sham), group 2 (hemorrhage), group 3 (hemorrhage-liver injury), and group 4 (hemorrhage-liver injury/intestinal injury-peritonitis)...
