#1
Sunita Seshia, M Casey Gaunt, Beverly A Kidney, Marion L Jackson
BACKGROUND: Evidence suggests that administration of intravenous fluids impairs hemostasis. Thromboelastometry (TEM) may provide a more sensitive measure of the fluid effects on hemostasis than traditional coagulation tests. OBJECTIVE: The study aim was to determine if resuscitative fluid therapy affects hemostasis, as measured by TEM. MATERIALS AND METHODS: Using a randomized crossover design, 6 healthy dogs were administered intravenous colloid, crystalloid, and hypertonic saline at therapeutic doses...

INTRODUCTION: Haemostasis testing is influenced by many pre-analytical variables, such as storage time and temperature, which can affect the stability of coagulation factors and influence the results of coagulation assays. We investigated the stability of haemostasis tests after storage of aliquoted plasma at RT, including the variability of measurement principle and reagent used for determination. METHODS: Blood samples from 20 healthy volunteers were obtained, processed to PPP and aliquoted...

Objective: To explore the influences of ulinastatin on acute lung injury and time phase changes of coagulation parameters in rats with severe burn-blast combined injuries. Methods: One hundred and ninety-two Sprague-Dawley rats were divided into pure burn-blast combined injury group, ulinastatin+ burn-blast combined injury group, and sham injury group according to the random number table, with 64 rats in each group. Two groups of rats with combined burn-blast injuries were inflicted with moderate blast injuries with the newly self-made explosive device...

Background: Multiple myeloma (MM) is a neoplastic plasma cell disorder characterized by clonal proliferation of plasma cells in the bone marrow. Diverse hemostatic abnormalities have been reported in patients with myeloma which predispose to bleeding and also thrombosis. Methods: Complete blood count, biochemical parameters and parameters of hemostasis i.e. platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), factor VIII assay results, plasma fibrinogen, D-dimer and lupus anticoagulant, were assessed in 29 MM patients and 30 age matched controls...

INTRODUCTION: Abnormal coagulation tests have been observed in patients with primary hyperparathyroidism (HPT) suggesting a prothrombotic effect of parathyroid hormone (PTH). Vitamin D deficiency (VIDD) is the most frequent cause of secondary HPT. Aim of our study was to investigate the influence of HPT secondary to moderate-severe VIDD and vitamin D replacement on the coagulation and fibrinolysis system. SUBJECTS AND METHODS: Prospective cohort study of patients with vitamin D<25 nmol/l with and without HPT, and a control group of patients on vitamin D suppletion...

BACKGROUND: Remote ischemic conditioning (RIC) administered by non-lethal periods of extremity ischemia and reperfusion attenuates ischemia-reperfusion injury. We aimed to investigate the local and systemic coagulation marker response to flap ischemia-reperfusion injury, and the effects of RIC on coagulation markers following flap ischemia-reperfusion injury. METHODS: A musculocutaneous latissimus dorsi flap was subjected to 4 h of ischemia followed by 7 h of reperfusion in 16 female Danish Landrace pigs (39 kg)...

BACKGROUND: Coagulopathy is commonly observed after traumatic brain injury (TBI). However, it is not known whether using the standard independent predictors in conjunction with coagulation tests would improve their prognostic value. We determined the incidence of TBI-associated coagulopathy in patients with isolated TBI (iTBI), evaluated the prognostic value of coagulation tests for in-hospital mortality, and tested their predictive power for in-hospital mortality in patients with iTBI...

CONTEXT: Selaginella tamariscina (P. Beauv.) Spring (Selaginellaceae) (ST) has been widely used in China as a medicine for improving blood circulation. However, its processed product, S. tamariscina carbonisatus (STC), possesses opposite haemostatic activity. OBJECTIVE: To comprehensively evaluate the activity of ST and STC on physiological coagulation system of rats, and seek potential active substances accounting for the activity transformation of ST during processing...

RATIONALE: Tigecycline is the first member of the glycylcycline family. There are rarely reports of tigecycline causing coagulopathy and hypofibrinogenemia until now. We report a case on tigecycline-associated coagulopathy and hypofibrinogenemia and discuss the characteristics of the adverse reaction. PATIENT CONCERNS: A 47-year-old male patient with severe acute cholangitis who developed sepsis was treated with a high dosage (100 mg twice daily) of tigecycline...

The aim was to evaluate the protective effects of total flavones of Elaeagnus rhamnoides (L.) A. Nelson (TFE) against vascular endothelial injury in blood stasis model rats and explore the potential mechanisms preliminarily. The model of blood stasis rat model with vascular endothelial injury was induced by subcutaneous injection of adrenaline combined with ice-water bath. Whole blood viscosity (WBV), histological examination, and prothrombin time (PT), activated partial thromboplastin time (APTT), and fibrinogen (FIB) were measured...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is associated with a systemic procoagulant hypofibrinolysis state that is considered as a risk factor for microangiopathy and peripheral vascular diseases. Swimming exercise ameliorates the metabolic dysfunction in type 2 diabetes. Vitamin E is a natural antioxidant that reduces the risk of endothelial dysfunction in metabolic syndrome. The aim of the present study is to investigate the effect of combined swimming exercise with vitamin E on coagulation as well as blood fibrinolysis markers in rats with NAFLD...

Standard laboratory tests (SLTs) of coagulation are in common use in clinical practice. We aimed to determine the association between SLTs and functional tests of coagulation in blood samples diluted with balanced crystalloid and colloid solutions in an ex vivo setting. The study group comprised 32 healthy young male volunteers. Whole blood samples were diluted at a 4:1 ratio with balanced crystalloid (Plasmalyte®) and two balanced colloids, 6% hydroxyethyl starch 130/0.4 (Volulyte®) and succinylated gelatin (Geloplasma®)...

Rhabdophis lateralis, a colubrid snake distributed throughout the continent of Asia, has recently undergone taxonomic revisions. Previously, Rhabdophis lateralis was classified as a subspecies of R. tigrinus (Yamakagashi) until 2012, when several genetic differences were discovered which classified this snake as its own species. To elucidate the toxicity of venom from this poorly studied colubrid, various biological activities were compared between the venom from the two snake species. The components of their venom were compared by the elution profiles of reversed-phase HPLC and SDS-PAGE, and gel filtrated fractions were tested for effects on blood coagulation...

Primary hemostasis begins with endothelial injury. VWF, produced by endothelial cells, binds to platelets and links them to subendothelial collagen. Platelet-derived ADP and thromboxane activate non-adhered platelets via their GPIIb/IIIa receptors, allowing these platelets to participate in platelet aggregation. Secondary hemostasis is initiated with the binding of factor VII to extravascular tissue factor (TF). Factors II, VII, IX and X are vitamin K-dependent factors. The role of vitamin K is to assist in the addition of gamma carboxylate groups to glutamic acids in the "GLA" domains of these factors...

The prothrombotic state in type 1 diabetes mellitus (T1DM) has been reported as a plausible cause of vascular complications. Rotational thromboelastometry (ROTEM) assay enables the global assessment of coagulation status. This study aimed to assess hypercoagulability in children with T1DM using ROTEM. A total of 43 T1DM children (20 females and 23 males) aged 2-18 years and age- and sex-matched 30 healthy control subjects were enrolled in the study group. ROTEM assays [intrinsic TEM (INTEM) and extrinsic TEM (EXTEM)] were used to measure and analyze coagulation time (CT), clot formation time, maximum clot firmness (MCF)...
