Socioeconomic status and determinants of hemostatic function in healthy women. (2/1215)

Hemostatic factors are reported to be associated with coronary heart disease (CHD). Socioeconomic status (SES) is 1 of the determinants of the hemostatic profile, but the factors underlying this association are not well known. Our aim was to examine determinants of the socioeconomic differences in hemostatic profile. Between 1991 and 1994, we studied 300 healthy women, aged 30 to 65 years, who were representative of women living in the greater Stockholm area. Fibrinogen, factor VII mass concentration (FVII:Ag), activated factor VII (FVIIa), von Willebrand factor (vWF), and plasminogen activator inhibitor-1 (PAI-1) were measured. Educational attainment was used as a measure of SES. Low educational level and an unfavorable hemostatic profile were both associated with older age, unhealthful life style, psychosocial stress, atherogenic biochemical factors, and hypertension. Levels of hemostatic factors increased with lower educational attainment. Independently of age, the differences between the lowest (mandatory) and highest (college/university) education in FVII:Ag levels were 41 microg/L (95% confidence interval [CI], 15 to 66 microg/L, P=0.001), 0.26 g/L (95% CI, 0.10 to 0.42 g/L, P=0.001) in fibrinogen levels, and 0.11 U/mL (95% CI, 0.09 to 0.12 U/mL, P=0.03) in levels of vWF. The corresponding differences in FVIIa and PAI-1 were not statistically significant. With further adjustment for menopausal status, family history of CHD, marital status, psychosocial stress, lifestyle patterns, biochemical factors, and hypertension, statistically significant differences between mandatory and college/university education were observed in FVII:Ag (difference=34 microg/L; 95% CI, 2 to 65 microg/L, P=0.05) but not in fibrinogen (difference=0.03 g/L; 95% CI, -0.13 to 0.19 g/L, P=0.92) or in vWF (difference=0.06 U/mL; 95% CI, -0.10 to 0.22 U/mL, P=0.45). An educational gradient was most consistent and statistically significant for FVII:Ag, fibrinogen, and vWF. Age, psychosocial stress, unhealthful life style, atherogenic biochemical factors, and hypertension mediated the association of low educational level with elevated levels of fibrinogen and vWF. Psychosocial stress and unhealthful life style were the most important contributing factors. There was an independent association between education and FVII:Ag, which could not be explained by any of these factors.  (+info)

Alpha2-antiplasmin gene deficiency in mice is associated with enhanced fibrinolytic potential without overt bleeding. (3/1215)

alpha2-antiplasmin (alpha2-AP) is the main physiologic plasmin inhibitor in mammalian plasma. Inactivation of the murine alpha2-AP gene was achieved by replacing, through homologous recombination in embryonic stem cells, a 7-kb genomic sequence encoding the entire murine protein (exon 2 through part of exon 10, including the stop codon) with the neomycin resistance expression cassette. Germline transmission of the mutated allele was confirmed by Southern blot analysis. Mendelian inheritance of the inactivated alpha2-AP allele was observed, and homozygous deficient (alpha2-AP-/-) mice displayed normal fertility, viability, and development. Reverse transcription-polymerase chain reaction confirmed the absence of alpha2-AP mRNA in kidney and liver from alpha2-AP-/- mice, in contrast to wild-type (alpha2-AP+/+) mice. Immunologic and functional alpha2-AP levels were undetectable in plasma of alpha2-AP-/- mice, and were about half of wild-type in heterozygous littermates (alpha2-AP+/-). Other hemostasis parameters, including plasminogen activator inhibitor-1, plasminogen, fibrinogen, hemoglobin, hematocrit, and blood cell counts were comparable for alpha2-AP+/+, alpha2-AP+/-, and alpha2-AP-/- mice. After amputation of tail or toe tips, bleeding stopped spontaneously in alpha2-AP+/+, as well as in alpha2-AP+/- and alpha2-AP-/- mice. Spontaneous lysis after 4 hours of intravenously injected 125I-fibrin-labeled plasma clots was significantly higher in alpha2-AP-/- than in alpha2-AP+/+ mice when injecting clots prepared from alpha2-AP+/+ plasma (78% +/- 5% v 46% +/- 9%; mean +/- SEM, n = 6 to 7; P =.02) or from alpha2-AP-/- plasma (81% +/- 5% v 46% +/- 5%; mean +/- SEM, n = 5; P =.008). Four to 8 hours after endotoxin injection, fibrin deposition in the kidneys was significantly reduced in alpha2-AP-/- mice, as compared with alpha2-AP+/+ mice (P +info)

Thrombelastographic changes and early rebleeding in cirrhotic patients with variceal bleeding. (4/1215)

BACKGROUND: Routine coagulation tests do not necessarily reflect haemostasis in vivo in cirrhotic patients, particularly those who have bleeding varices. Thrombelastography (TEG) can provide a global assessment of haemostatic function from initial clot formation to clot dissolution. AIM: To evaluate TEG changes in cirrhotic patients with variceal bleeding and their association with early rebleeding. PATIENTS/METHODS: Twenty cirrhotic patients with active variceal bleeding had serial TEG and routine coagulation tests daily for seven days. The TEG variables before the day of rebleeding (n = 6) were compared with those of patients without rebleeding (n = 14). RESULTS: Baseline characteristics of the rebleeding and non-rebleeding groups were comparable apart from a higher incidence of uncontrolled infection on the day of rebleeding in the rebleeding group (p = 0.007). The patients in the rebleeding group were more hypocoagulable before the day of rebleeding as shown by longer r (42 v 24 mm, p < 0.001) and k (48 v 13 mm, p < 0.001) and smaller a (12 v 38 degrees, p < 0.001) compared with the mean of daily results of the non-rebleeding group. Routine coagulation tests, however, showed no significant differences between the two groups. CONCLUSION: The results of serial TEG measurements suggest that hypocoagulability may be associated with early rebleeding in cirrhotic patients.  (+info)

Pravastatin therapy in hyperlipidemia: effects on thrombus formation and the systemic hemostatic profile. (5/1215)

OBJECTIVES: The study sought to determine the effects of lipid-lowering with pravastatin on the systemic fibrinolytic profile and on thrombus formation under dynamic flow conditions. BACKGROUND: Lowering cholesterol (C) decreases clinical events in coronary artery disease (CAD) patients, but an analysis of the effects of lipid-lowering on the entire hemostatic and thrombotic profile has not been conducted. METHODS: We prospectively studied 93 stable patients with untreated low-density lipoprotein cholesterol (LDL-C) >145 mg/dl. The CAD patients received pravastatin, and non-CAD patients were randomized to pravastatin versus placebo (double-blind). Thrombus formation upon an injured vascular surface was assessed in a substudy of 40 patients with a previously validated ex vivo perfusion chamber system. Systemic hemostatic markers and thrombus formation were evaluated at baseline, three and six months. RESULTS: Placebo produced no changes in either the lipid profile, any of the hemostatic markers, or the ex vivo thrombus formation. Both pravastatin groups (CAD and non-CAD) showed decreased LDL-C by 30% within 6 weeks (188 to 126 mg/dl, p < 0.001 vs. baseline), and decreased plasminogen activator inhibitor-1 at 3- and 6-month follow-up compared to baseline (15% to 18% decrease at 3 months and 21% to 23% at 6 months). For the tissue plasminogen activator antigen, CAD and non-CAD groups showed significant decreases at 6 months compared to baseline (10% and 13%, respectively). No significant changes were observed with treatment in d-dimer, fibrinopeptide A, prothrombin fragment F1.2, factor VIIa, von Willebrand factor, or C-reactive protein. Fibrinogen levels were significantly increased at 6 months compared to baseline, though still below the upper normal limit. In the perfusion chamber substudy, there was a decrease in thrombus area in non-CAD patients treated with pravastatin at both 3 and 6 months compared to baseline (by 21% and 34%, respectively). The CAD patients showed decreases in thrombus formation by 13% at 3 months, and by 16% at 6 months. The change in LDL-C- correlated modestly with the change in thrombus formation (r = 0.49; p < 0.01). CONCLUSIONS: Pravastatin therapy significantly decreased thrombus formation and improved the fibrinolytic profile in patients with and without CAD. These early effects may, in part, explain the benefit rendered in primary and secondary prevention of CAD.  (+info)

Neutrophil activation and hemostatic changes in healthy donors receiving granulocyte colony-stimulating factor. (6/1215)

Granulocyte colony-stimulating factor (G-CSF) enhances neutrophil functions in vitro and in vivo. It is known that neutrophil-derived products can alter the hemostatic balance. To understand whether polymorphonuclear leukocyte (PMN) activation, measured as PMN degranulation and phenotypical change, may be associated to hemostatic alterations in vivo, we have studied the effect of recombinant human G-CSF (rHuG-CSF) administration on leukocyte parameters and hemostatic variables in healthy donors of hematopoietic progenitor cells (HPCs). Twenty-six consecutive healthy donors receiving 10 micrograms/kg/d rHuG-CSF subcutaneously for 5 to 7 days to mobilize HPCs for allogeneic transplants were included in the study. All of them responded to rHuG-CSF with a significant white blood cell count increase. Blood samples were drawn before therapy on days 2 and 5 and 1 week after stopping rHuG-CSF treatment. The following parameters were evaluated: (1) PMN activation parameters, ie, surface CD11b/CD18 antigen expression, plasma elastase antigen levels and cellular elastase activity; (2) plasma markers of endothelium activation, ie, thrombomodulin (TM) and von Willebrand factor (vWF) antigens; (3) plasma markers of blood coagulation activation, ie, F1+2, TAT complex, D-dimer; and (4) mononuclear cell (MNC) procoagulant activity (PCA) expression. The results show that, after starting rHuG-CSF, an in vivo PMN activation occurred, as demonstrated by the significant increment of surface CD11b/CD18 and plasma elastase antigen levels. Moreover, PMN cellular elastase activity, which was significantly increased at 1 day of treatment, returned to baseline at day 5 to 6, in correspondence with the elastase antigen peak in the circulation. This change was accompanied by a parallel significant increase in plasma levels of the two endothelial and the three coagulation markers. The PCA generated in vitro by unstimulated MNC isolated from rHuG-CSF-treated subjects was not different from that of control cells from untreated subjects. However, endotoxin-stimulated MNC isolated from on-treatment individuals produced significantly more PCA compared with both baseline and control samples. All of the parameters were decreased or normal 1 week after stopping treatment. These data show that rHuG-CSF induces PMN activation and transiently affects some hemostatic variables in healthy HPC donor subjects. The clinical significance of these findings remains to be established.  (+info)

Hormone replacement therapy, inflammation, and hemostasis in elderly women. (7/1215)

Lipid-lowering by postmenopausal hormone therapy (HRT) explains only partly the assumed coronary risk reduction associated with therapy. To explore other possible mechanisms, we studied associations of HRT use with inflammation and hemostasis risk markers in women >/=65 years of age. Subjects were selected from 3393 participants in the fourth year examination of the Cardiovascular Health Study, an observational study of vascular disease risk factors. After excluding women with vascular disease, we compared levels of inflammation and hemostasis variables in the 230 women using unopposed estrogen and 60 using estrogen/progestin, with those of 196 nonusers selected as controls. Compared with nonusers, unopposed estrogen use was associated with 59% higher mean C-reactive protein (P<0.001), but with modestly lower levels of other inflammation indicators, fibrinogen, and alpha-1 acid glycoprotein (P<0.001). Factor VIIc was 16% higher among estrogen users (P<0.001), but this was not associated with higher thrombin production (prothrombin fragment 1-2), or increased fibrin breakdown (D-dimer). Concentration of plasminogen activator inhibitor-1 was 50% lower in both using groups (P<0.001) compared with nonusers, and this was associated with higher plasmin-antiplasmin complex: 8% higher in estrogen and 18% higher in estrogen/progestin users (P<0. 05). Relationships between the markers and hormone use were less pronounced in estrogen/progestin users, with no association for C-reactive protein except in women in upper 2 tertiles of body mass index (P for interaction, 0.02). The direction and strength of the associations of HRT use with inflammation markers differed depending on the protein, so it is not clear whether HRT confers coronary risk reduction through an inflammation-sensitive mechanism. Associations with hemostasis markers indicated no association with evidence of procoagulation and a possible association with increased fibrinolytic activity.  (+info)

Strategy for balancing anticoagulation and hemostasis in aortocoronary bypass surgery: blood conservation and graft patency. (8/1215)

The minimal effective dose of aprotinin on hemostasis under normothermic perfusion, the influence of anticoagulant therapy on graft patency, and the thromboembolic and hemorrhagic events were investigated after aortocoronary bypass graft operation (CABG). One hundred CABG patients under normothermic perfusion were randomly divided into the following groups: (1) coumadin plus acetylsalicylic acid (ASA) (n=32); no aprotinin used during cardiopulmonary bypass (CPB); (2) minimal-dose, 10(6) KIU during CPB, aprotinin used, followed by ASA and coumadin (n=36); and (3) very low-dose, total of 2x10(6) KIU before CPB and during CPB; aprotinin used; anticoagulation therapy with heparin early after surgery and followed by replacement with ASA and coumadin (n=32). The patency of arterial grafts was 100% in all groups. The patency of vein grafts was 95-98% and there was no difference among the groups. The blood loss was significantly reduced in both aprotinin groups (groups 2 and 3) compared to the coumadin plus ASA group, although no difference existed between the 2 aprotinin groups. Postoperative thrombotic and hemorrhagic events were not observed in any group. From this study, it was concluded that 10(6) KIU aprotinin in pump-prime-only followed by oral ASA and coumadin was the recommendation from the benefit/cost consideration.  (+info)

A library of hyperbranched polyglycerols (HPGs) functionalized with different mole fractions of zwitterionic sulfabetaine and cationic quaternary ammonium ligands was synthesized and characterized. A post-polymerization method was employed that utilized double bond moieties on the dendritic HPG for the coupling of thiol-terminated ligands via UV initiated thiol-ene click chemistry. The proportions of different ligands were precisely controlled by varying the ligand concentration during the irradiation process. The effect of the polymer library on hemostasis was investigated using whole human blood. It was found that polymer with ≥40% of alkenes converted to positive charges and the remainder to sulfabetaines caused hemagglutination at ≥1 mg/mL, without causing red blood cell lysis. The quaternary ammonium groups can interact with the negative charged sites on the membranes of erythrocytes, which provides the bioadhesion. The zwitterionic sulfabetaine evidently provides a hydration layer to ...
Epidemiological, clinical, and experimental studies have shown that dyslipidemia associated with insulin resistance and hypertension also may include a procoagulant state with activation of the coagulation system and inhibition of the fibrinolytic activities.11 24 25 In the early prospective epidemiological studies, it was shown that FVIIc, fibrinogen, PAI-1a, and tPAag may represent independent risk factors for development of CHD.11 24 25 In a recent study of patients with combined hyperlipemia, we have confirmed that FVIIag and FVIIc are correlated with the triglyceride-rich lipoproteins, particularly with the concentration of intermediate density lipoproteins (IDL) TAGs.21 TFPIa showed a significant correlation with the concentration of LDL, a lipoprotein fraction also associated with increased risk for CHD.. In human plasma, 80% of TFPI is bound to lipoproteins, especially LDL, whereas 10% to 20% circulates in a free form.26 A positive correlation between the total plasma TFPI activity and ...
BACKGROUND: Previous studies have suggested that several hemostatic and inflammatory variables, which are risk predictors for arterial or venous thrombosis, increase with age. However, there is a lack of data from large population studies for reliable estimates of reference ranges. OBJECTIVES: To establish reliable reference ranges of hemostatic and inflammatory variables for 5-year age groups in older men and their implications for pathogenesis and diagnosis. PATIENTS AND METHODS: A total of 3861 men aged 60-79 years at the 20 years follow-up of the British Regional Heart Study. RESULTS: Several variables increased with age. The greatest median increases between 60-64 and 75-79 years age groups were observed for fibrin D-dimer (91%) and C-reactive protein (CRP) (57%). Significant median increases were also observed for von Willebrand factor antigen (23%), tissue plasminogen activator antigen (11%), factor VIII (10%), and fibrinogen (8%). In contrast, levels of classical cardiovascular risk factors

The global coagulation analyzers market is estimated to grow at a lower CAGR in developed countries; however, it is expected to witness high growth in emerging countries such as China, India, and Brazil in the next five years. Growth in the coagulation analyzers market is driven by factors such as increasing adoption of automated hemostasis instruments by diagnostics laboratories, development of high-throughput hemostasis analyzers, developments in high-sensitivity point-of-care coagulation analyzers, and introduction of technologically advanced hemostasis instruments. However, slow adoption of advanced hemostasis instruments in emerging economies and high cost of hemostasis analyzers are restraining the growth of this market.. In this report, the global coagulation analyzers market has been segmented based on the type of product (clinical laboratory analyzers, point of care testing analyzers) end users (diagnostic laboratories, stand-alone hospitals, research institutes, and other end users), ...
There is evidence from recent studies that VEGF is stored in human megakaryocytes and is released from platelets on stimulation with thrombin.14 15 These studies were performed under in vitro conditions in the absence of important determinants of in vivo clotting such as the vessel wall, blood flow, and clotting proteases. Thus, it is uncertain if their in vitro observations are of relevance for the in vivo circumstances. The technique applied in our study covers many mechanisms relevant for hemostatic plug formation in vivo. It is performed directly on human subjects and takes into account the interaction between blood cells, endothelium, and various plasma proteins under physiological flow conditions. Thus, we believe that the experimental approach applied in this study is appropriate for investigating the mechanisms important for plug formation under conditions close to the in vivo circumstances.. The principal finding of our study was that much higher concentrations of VEGF are detectable in ...
INTRODUCTION: Cirrhosis is one of the commonest diseases affecting man. Hepatic cirrhosis can occur at any age and often causes prolonged morbidity. It frequently manifests itself in younger adults and is an important cause of premature death. Liver disease produces a diverse range of haemotological effects. Liver disease can affect all the formed elements of blood RBCS, WBCS, and platelets. Liver disease has important effects on haemostasis. The liver plays a central role in the synthesis of many proteins and the maintenance of metabolic homeostasis. It is therefore not surprising that the development of clinically important liver diseases is accompanied by diverse manifestations. Although some functions are more sensitive than others, the liver has considerable reserve capacity, so, minimal or even moderate cell injury may not be reflected by measurable functional changes. Impaired liver functions are most evident in the patient with advanced liver disease, and the manifestations are similar ...
The process of preventing blood loss from a vessel or organ of the body is referred to as hemostasis. The term comes from the Ancient Greek roots heme meaning blood, and stasis meaning halting; Put together means the halting of the blood.[3] The origin of hemostasis dates back as far as ancient Greece; first referenced to being used in the Battle of Troy. It started with the realization that excessive bleeding inevitably equaled death. Vegetable and mineral styptics were used on large wounds by the Greeks and Romans until the takeover of Egypt around 332BC by Greece. At this time many more advances in the general medical field were developed through the study of Egyptian mummification practice, which led to greater knowledge of the hemostatic process. It was during this time that many of the veins and arteries running throughout the human body were found and the directions in which they traveled. Doctors of this time realized if these were plugged, blood could not continue to flow out of ...

A method and system for achieving hemostasis (the stoppage of bleeding) is described. RF (radio frequency) energy is used to ablate the surface of tissue to stop bleeding. The depth of destruction of the tissue can be controlled so as to desiccate and coagulate the tissue. In one implementation, an electrode carrier including bipolar electrodes is applied to the tissue, and RF energy transmitted through the bipolar electrodes to ablate the tissue. A layer of desiccated tissue can be created as well as coagulation of the tissue to achieve hemostasis.

Blood is a vital part of the human physiology; a transport system that brings nutrients and oxygen to sustain living cells and simultaneously facilitates the removal of carbon dioxide and other waste products from the body. To assure the continuity of these functions, it is of uttermost importance to keep the flowing blood inside the vascular system at any cost. The principal components of the haemostatic system are the blood platelets and the plasma coagulation system, both working in concert to create a blood stopping haemostatic plug when a vessel is ruptured. In modern health care, methods for treatment and diagnostics often implicate the contact between blood and artificial materials (biomaterials). Biomaterial surfaces may activate platelets and the coagulation cascade by exposing a surface that during blood contact shares certain characteristics with surfaces found at the site of vascular injury. Therefore it is of great importance that the mechanisms behind the interactions between ...

The tissue factor (TF) pathway serves both hemostasis and cell signaling, but how cells control these divergent functions of TF remains incompletely understood. TF is the receptor and scaffold of coagulation proteases cleaving protease activated receptor (PAR) 2 that plays pivotal roles in angiogenesis and tumor development. Here we demonstrate that coagulation factor (F) VIIa elicits TF cytoplasmic domain-dependent pro-angiogenic cell signaling independent of the alternative PAR2 activator matriptase. We identify a Lys-Gly-Glu (KGE) integrin binding motif in the FVIIa protease domain that is required for association of the TF-FVIIa complex with the active conformer of integrin β1 ...

This complication can be severe enough to lead to hemorrhage or thrombosis. A study was undertaken to determine if the hemostatic abnormalities are reliable indicators of outcome. Hemostasis in 269 patients with head injuries alone was screened using platelet count (PC), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin clotting time (TCT), fibrinogen assay (FIB), level of fibrin-fibrinogen degradation products (FDP), and disseminated intravascular coagulation (DIC) score in the first 24 hours after injury. Test restults were compared with the outcome (discharged or dead) in the entire ...
Pregnancy is a risk factor for venous thrombosis and the incidence of venous thromboembolism during normal pregnancy is 6-fold higher during pregnancy than in the general female population of child-bearing age. This incidence is, however, remarkably low given the increases in markers of haemostatic activation observed during normal pregnancy. During normal healthy pregnancy there are substantial changes in the haemostatic system, many of which are procoagulant and supposed to be in preparation for the haemostatic challenge of delivery. Normal haemostasis requires a balance between coagulation and fibrinolysis to maintain the integrity of the vasculature, and complex physiological changes are evident during pregnancy which appear to ensure a constant coagulation/fibrinolysis balance. This balance is maintained, at least partly, by an increase in fibrinolytic activity, but decreases in other factors such as factor XI and monocyte tissue factor expression may also serve to counterbalance ...

Objective: Complement proteins have been associated with atherosclerosis and cardiovascular risk factors. Recent data suggest a potential role of complement protein C3 in clot stability with hypofibrinolytic and prothrombotic features. Women after menopause are at greater risk of cardiovascular disease and have significantly higher levels of C3 compared with younger women. To better understand the association between complement proteins and atherosclerosis we evaluated the cross-sectional associations between complement proteins C3 and C4 and hemostatic markers (factor VIIc, fibrinogen, plasminogen activator inhibitor-1 (PAI-1) antigen and tissue plasminogen activator (tPA) antigen) in a sample of midlife women.. Design: Pilot data from the Study of Womens Health Across the Nation (SWAN) Pittsburgh site were used. Both C3 and C4 were measured using frozen serum specimens by immunoturbidimetric assay. Data for hemostatic markers were available in SWAN Core data (factor VIIc and fibrinogen were ...
TY - JOUR. T1 - Inherited Disorders of Hemostasis in Dogs and Cats. AU - Barr, James W.. AU - McMichael, Maureen. PY - 2012/5/1. Y1 - 2012/5/1. N2 - Inherited disorders of hemostasis encompass abnormalities in primary hemostasis, coagulation, and fibrinolysis resulting from genetic mutations. There is significant variation in the phenotype expressed ranging from life limiting to the absence of overt clinical signs. Von Willebrand disease is the most common primary hemostatic disorder in dogs, and hemophilia A is the most common coagulation factor disorder. The diagnosis of inherited bleeding disorders is made by functional and/or quantitative evaluation. Genetic testing has added to the knowledge base, allowing prevention through targeted breeding. Avoidance of trauma and injury is paramount in the prevention of bleeding in animals diagnosed with inherited hemostatic disorders. Current therapeutic options include platelet transfusions, broad replacement of coagulation factors (e.g., plasma), ...

Those who have inadequate haemostasis after initial standardised administration of coagulation factors and receive placebo. (Placebo arm). We anticipate from our preliminary series that 50% of enrolled subjects will achieve haemostasis after the initial standardised dose of coagulation factors and therefore dont receive trial medication. Identical data will be collected and will form an observational subgroup for analysis.. The protocol allows for open label administration of rVIIa if adequate haemostasis is not achieved after two standardised administrations of coagulation factors and the trial medication. This would be within 2 hours of the completion of the first administration. Primary endpoint will be adequate haemostasis to enable chest closure after administration of trial medication without the need for further intervention to improve coagulation..

BACKGROUND & AIMS: Patients undergoing liver transplantation have complex changes in their hemostatic system, and the net effect of these changes appears a rebalanced hemostatic profile. Recently, a process called NETosis, in which a neutrophil expels DNA and proteins that form a web-like structure, has been described as a mechanism of pathogen entrapment. Increasing evidence suggests a pivotal role for neutrophil extracellular traps (NETs), and their main component cell-free DNA in activation of coagulation. As liver transplantation is associated with substantial (hepatocyte) cell death and intrahepatic neutrophil accumulation, NETs might play an important role in the hemostatic balance during liver transplantation. Here, we determined markers for NETs in plasma of patients undergoing a liver transplantation and examined their association with activation of coagulation.. METHODS: Markers for NETs and markers for activation of coagulation were determined in serial plasma samples taken from ...

Blood coagulation functions as part of the innate immune system by preventing bacterial invasion and it is critical to stopping blood loss (hemostasis). Coagulation involves the external membrane surface of activated platelets and leukocytes. Using lipidomic, genetic, biochemical, and mathematical modeling approaches, we found that enzymatically oxidized phospholipids (eoxPLs) generated by the activity of leukocyte or platelet lipoxygenases (LOXs) were required for normal hemostasis and promoted coagulation factor activities in a Ca2+- and phosphatidylserine (PS)- dependent manner. In wild-type mice, hydroxyeicosatetraenoic acid-phospholipids (HETE-PLs) enhanced coagulation and restored normal hemostasis in clotting-deficient animals genetically lacking p12-LOX or 12/15-LOX activity. Murine platelets generated 22 eoxPL species, all of which were missing in the absence of p12-LOX. Humans with the thrombotic disorder antiphospholipid syndrome (APS) had statistically significantly increased ...

Background Rapid point-of-care (POC) assessment of hemostasis is certainly clinically important in patients with a variety of coagulation factor and platelet defects who have bleeding disorders. distinguishing among coagulation disorders as compared to conventional screening coagulation tests. Moreover, the ClotChip r,max parameter detected platelet function inhibition induced by aspirin and exhibited strong positive correlation with light transmission aggregometry. Conclusions This study demonstrates that ClotChip assesses multiple aspects of the hemostatic process in whole blood on a single disposable cartridge, highlighting its potential as a POC platform for rapid, comprehensive hemostatic analysis. Introduction Early identification of hemostatic dysregulation and bleeding risk is important in the management of patients who are critically ill, severely injured, or on antiplatelet/anticoagulation therapies [1]. order Iressa Conventional laboratory-structured coagulation exams are time-eating, ...
Recent studies have highlighted the importance of expeditious transfusion of plasma, platelets and red blood cells in a 1:1:1 ratio for severe trauma patients who are at risk of exsanguination. Since thawing plasma can be time-consuming, a recent study published in TRANSFUSION examined the hemostatic properties of thawed and liquid plasma over several days of storage. Briefly, during initial processing after donation 17 pooled ABO-matched plasma units were split into a liquid plasma unit and a frozen unit (subsequently thawed and stored for up to five days), and multiple hemostasis parameters, coagulation factors, and platelet activation assays were performed. A further 119 liquid plasma samples were analyzed for platelet activation and cellular content. Liquid plasma at day seven was comparable to thawed plasma at day five by every assay. However, after 11 days of storage, coagulation factors started to decline in liquid plasma, and cold-induced contact activation was observed after 28 days of ...
To differentiate the causes of bleeding disorders requires a basic understanding of the hemostatic process and the proper interpretation of history, physical examination, and laboratory tests. A brief overview of the hemostatic process is presented. Tables and flow charts are provided to assist in developing a sound clinical approach to the bleeding patient through the proper assessment of history, physical examination findings, and laboratory tests. Categories of inherited and acquired bleeding disorders are briefly presented.
A system for facilitating hemostasis of a puncture site in a blood vessel injects an absorbable sponge pledget in a hydrated state at an exterior of the blood vessel puncture to facilitate hemostasis. The system includes a tract dilator for locating the puncture, an introducer, and a plunger. The introducer includes a staging chamber for receiving the absorbent sponge pledget and a delivery chamber having a diameter smaller than a diameter of the staging chamber into which a hydrated pledget passes. The pledget is hydrated and compressed within the introducer and then ejected with the plunger to the delivery site to facilitate hemostasis of the blood vessel puncture. The system delivers the absorbable sponge pledget over a guidewire to ensure the proper positioning of the pledget over the puncture. The implanted absorbable sponge once delivered expands rapidly to fill the target site and is absorbed by the body over time.

Supplement Hemostasis is a process that stops or arrest bleeding. It helps keep the blood within the damaged blood vessel. This is the first stage of tissue repair and wound healing. Hemostasis involves three major stages: (1) vascular spasm or vasoconstriction, temporary blockage of a break by a platelet plug, and (3) blood coagulation (clot formation). During vascular spasm or vasoconstriction, the blood vessels constrict. The smooth muscle cells in the damaged blood vessel constrict as an immediate reflex. This would reduce the blood flowing through the damaged blood vessel. Thus, it would hamper the progression of blood loss. Vasoconstriction is promoted when collagen from the injured site is exposed. The platelets adhere to the site and release cytoplasmic contents that promote vasoconstriction. Apart from vasoconstriction, the platelets also promote the formation of a platelet plug. The platelets express receptors that enable interacting with other platelets to aggregate and adhere to one ...

Hemostasis undergoes major changes in normal pregnancy. These changes contribute in maintaining placental function and preventing excessive bleeding. Most changes in coagulation create a state of hypercoagulability that serves to protect the mother from hemorrhage during delivery. Unfortunately, these changes can also can predispose women to thromboembolism. It is important to note that complications with pregnancy such as pre-eclampsia, hemorrhage, infection, etc. can have multiple deleterious coagulopathies which are not specifically discussed here.. Platelets: Thrombocytopenia is the most common hemostatic abnormality observed in healthy women. Part of this is due to hemodilutional affects but increases in mean platelet volume suggests that there exists compensated platelet destruction as well.. Coagulation System: In normal pregnancy you see significant increases in factor VII, VIII, IX, X, XII, vWF and fibrinogen but relatively no changes to factors II and V. Protein C and anti-thrombin ...

The underlying scientific basis for blood clotting and hemostasis is discussed in detail in the articles, coagulation, hemostasis and related articles. The discussion here is limited to the common practical aspects of blood clot formation which manifest as bleeding. Some medical conditions can also make patients susceptible to bleeding. These are conditions that affect the normal hemostatic (bleeding-control) functions of the body. Such conditions either are, or cause, bleeding diatheses. Hemostasis involves several components. The main components of the hemostatic system include platelets and the coagulation system. Platelets are small blood components that form a plug in the blood vessel wall that stops bleeding. Platelets also produce a variety of substances that stimulate the production of a blood clot. One of the most common causes of increased bleeding risk is exposure to nonsteroidal anti-inflammatory drugs (NSAIDs). The prototype for these drugs is aspirin, which inhibits the production ...
Hemostasis interrupts bleeding from disrupted blood vessels by activating platelet aggregation and coagulation. If uncontrolled, this process generates obstructive thrombi and the resulting endoluminal clot is termed thrombosis or atherothrombosis when occurring on atherosclerotic plaques. Whether some molecular mechanisms differentiate controlled hemostasis from pathological thrombosis is not clear. We hypothesized here that the prostaglandin PGE2 activating its platelet receptor EP3 might play such a role in mice. First, we confirmed that EP3 gene deletion does not increase mouse bleeding from tail (307±31 µl, n=15 Ep3+/+ mice versus 364±32 µl, n=18 Ep3-/- mice, P,0.05). We observed similar differences when investigating tail, liver or cerebral bleeding in mice receiving DG-041, a specific blocker for EP3. Then we showed that blockade of EP3 with DG-041 prevented thrombosis on arachidonic acid- and ferric chloride- induced mouse models of arterial thrombosis. In addition, DG-041 ...

A sticking material for hemostasis has a flexible strip-shaped base member having a high recovery property, a main surface, and side edges extending in a first longitudinal direction. An adhesive layer is disposed on the main surface of the base member. A pad is disposed on the adhesive layer and extends in a second longitudinal direction substantially transverse to the first longitudinal direction such that a space is defined between the pad and each of the side edges of the base member. The pad is of a size sufficient to exert pressure at a puncture area including punctures of both a blood vessel and a skin surface. The pad has a slight elasticity and a hardness capable of securely exerting pressure on the punctures by a shrinking action of the base member when the base member is adhered to the skin surface while being stretched to secure the pad over the punctures. A pressure plate having a width equal to or less than the width of the base member may be interposed between the base member and the pad

Objective-To determine whether activation of hemostatic function (thrombosis and fibrinolysis) is associated with cognitive decline in older people. Methods and Results-We studied 5804 people (age, 70-82 years) in the Prospective Study of Pravastatin in the Elderly at Risk (PROSPER). Mean follow-up was 3.2 years, including annual measurement of speed of information processing (letter, digit coding, and Stroop), verbal memory (picture-word naming), and basic and instrumental activities of daily living. Raised levels of markers of thrombin generation (D-dimer and prothrombin fragment 1+2) were associated independently with increased rate of cognitive decline (eg, Stroop increased by 4.44 s [SEM, 0.68] in bottom tertile of D-dimer compared to 5.46 [SEM, 0.71] in highest tertile; P,0.05) and deterioration in activities of daily living. This increased rate of decline was attenuated but not removed when subjects with incident nonfatal stroke were omitted from the analysis. It also persisted when ...

Hemostasis commands special attention among physicians and investigators. The importance and appeal of this discipline rests on exciting scientific advances as well as its obvious clinical relevance. The mechanisms underlying the initiation and control of blood coagulation constitute a complex but beautifully integrated system of cellular and molecular interactions that fulfill a biological function of crucial importance. As summarized in Chapter 1, the circulation of blood cells and plasma through the vascular tree is essential for providing the bodys organs and tissues with nutrients and oxygen and for defense against infection and inflammation. Platelets, endothelial cells, and coagulation proteins cooperate in a complex and dynamic way to repair leaks in the vasculature and protect against hemorrhage in a high-pressure circulatory system. ...

SUMMARY Blood vessels, especially their endothelial lining, play a critical role in the maintenance of vascular fluidity, arrest of hemorrhage (hemostasis), prevention of occlusive vascular phenomena (thrombosis), and regulation of inflammatory cell processes.* The endothelium extends to all recesses of the body and maintains an intimate association with flowing blood and blood cells. However, endothelial cell morphologies, gene-expression profiles, and functions vary among different vascular beds. For example, in straight arterial segments, but not at branch points or curvatures of the arteries or veins, endothelial cells align themselves in parallel to the direction of blood flow. Similarly, endothelial cells in post capillary venules are primarily responsible for mediating adhesion and transmigration of leukocytes, whereas arteriolar endothelium is important for regulation of vasomotor tone. Proteomic studies have revealed that endothelial cells have the unique capacity to express and ...
