Systemic infection with Alaria americana (Trematoda). (1/5349)

Alaria americana is a trematode, the adult of which is found in mammalian carnivores. The first case of disseminated human infection by the mesocercarial stage of this worm occurred in a 24-year-old man. The infection possibly was acquired by the eating of inadequately cooked frogs, which are intermediate hosts of the worm. The diagnosis was made during life by lung biopsy and confirmed at autopsy. The mesocercariae were present in the stomach wall, lymph nodes, liver, myocardium, pancreas and surrounding adipose tissue, spleen, kidney, lungs, brain and spinal cord. There was no host reaction to the parasites. Granulomas were present in the stomach wall, lymph nodes and liver, but the worms were not identified in them. Hypersensitivity vasculitis and a bleeding diathesis due to disseminated intravascular coagulation and a circulating anticoagulant caused his death 8 days after the onset of his illness.  (+info)

Antiphospholipid, anti-beta 2-glycoprotein-I and anti-oxidized-low-density-lipoprotein antibodies in antiphospholipid syndrome. (2/5349)

Antiphospholipid antibodies (aPL), anti-beta 2-glycoprotein I (anti-beta 2-GPI) and anti-oxidized-low-density lipoprotein (LDL) antibodies are all implicated in the pathogenesis of antiphospholipid syndrome. To investigate whether different autoantibodies or combinations thereof produced distinct effects related to their antigenic specificities, we examined the frequencies of antiphospholipid syndrome (APS)-related features in the presence of different antibodies [aPL, beta 2-GPI, anti-oxidized low density lipoprotein (LDL)] in 125 patients with APS. Median follow-up was 72 months: 58 patients were diagnosed as primary APS and 67 as APS plus systemic lupus erythematosus (SLE). Anticardiolipin antibodies (aCL), anti-beta 2-GPI and anti-oxidized LDL antibodies were determined by ELISA; lupus anticoagulant (LA) by standard coagulometric methods. Univariate analysis showed that patients positive for anti-beta 2-GPI had a higher risk of recurrent thrombotic events (OR = 3.64, 95% CI, p = 0.01) and pregnancy loss (OR = 2.99, 95% CI, p = 0.004). Patients positive for anti-oxidized LDL antibodies had a 2.24-fold increase in the risk of arterial thrombosis (2.24, 95% CI, p = 0.03) and lower risk of thrombocytopenia (OR = 0.41 95% CI, p = 0.04). Patients positive for aCL antibodies had a higher risk of pregnancy loss (OR = 4.62 95% CI, p = 0.001). When these data were tested by multivariate logistic regression, the association between anti-beta 2-GPI and pregnancy loss and the negative association between anti-oxidized LDL antibodies and thrombocytopenia disappeared.  (+info)

Blood-borne tissue factor: another view of thrombosis. (3/5349)

Arterial thrombosis is considered to arise from the interaction of tissue factor (TF) in the vascular wall with platelets and coagulation factors in circulating blood. According to this paradigm, coagulation is initiated after a vessel is damaged and blood is exposed to vessel-wall TF. We have examined thrombus formation on pig arterial media (which contains no stainable TF) and on collagen-coated glass slides (which are devoid of TF) exposed to flowing native human blood. In both systems the thrombi that formed during a 5-min perfusion stained intensely for TF, much of which was not associated with cells. Antibodies against TF caused approximately 70% reduction in the amount of thrombus formed on the pig arterial media and also reduced thrombi on the collagen-coated glass slides. TF deposited on the slides was active, as there was abundant fibrin in the thrombi. Factor VIIai, a potent inhibitor of TF, essentially abolished fibrin production and markedly reduced the mass of the thrombi. Immunoelectron microscopy revealed TF-positive membrane vesicles that we frequently observed in large clusters near the surface of platelets. TF, measured by factor Xa formation, was extracted from whole blood and plasma of healthy subjects. By using immunostaining, TF-containing neutrophils and monocytes were identified in peripheral blood; our data raise the possibility that leukocytes are the main source of blood TF. We suggest that blood-borne TF is inherently thrombogenic and may be involved in thrombus propagation at the site of vascular injury.  (+info)

Endothelial implants inhibit intimal hyperplasia after porcine angioplasty. (4/5349)

The perivascular implantation of tissue-engineered endothelial cells around injured arteries offers an opportunity to study fundamental vascular physiology as well as restore and improve tissue function. Cell source is an important issue because the ability to implant either xenogeneic or allogeneic cells would greatly enhance the clinical applications of tissue-engineered grafts. We investigated the biological and immunological responses to endothelial cell xenografts and allografts in pigs 4 weeks after angioplasty of the carotid arteries. Porcine or bovine aortic endothelial cells were cultured within Gelfoam matrices and implanted in the perivascular space of 42 injured arteries. Both porcine and bovine endothelial cell grafts reduced the restenosis index compared with control by 54% and 46%, respectively. Perivascular heparin release devices, formulated to release heparin at twice the rate of release of heparan sulfate proteoglycan from endothelial cell implants, produced no significant reduction in the restenosis index. Endothelial cell implants also reduced occlusive thrombosis compared with control and heparin release devices. Host immune responses to endothelial implants were investigated by immunohistochemical examination of explanted devices and by immunocytochemistry of serum samples. The bovine cell grafts displayed infiltration of leukocytes, consisting primarily of lymphocytes, and caused an increase in antibodies detected in serum samples. Reduced cellular infiltration and no humoral response were detected in animals that received allografts. Despite the difference in immune response, the biological effects of xenografts or allografts did not differ significantly.  (+info)

The tourniquet in total knee arthroplasty. A prospective, randomised study. (5/5349)

We assessed the influence of the use of a tourniquet in total knee arthroplasty in a prospective, randomised study. After satisfying exclusion criteria, we divided 77 patients into two groups, one to undergo surgery with a tourniquet and one without. Both groups were well matched. The mean change in knee flexion in the group that had surgery without a tourniquet was significantly better at one week (p = 0.03) than in the other group, but movement was similar at six weeks and at four months. There was no significant difference in the surgical time, postoperative pain, need for analgesia, the volume collected in the drains, postoperative swelling, and the incidence of wound complications or of deep-venous thrombosis. We conclude that the use of a tourniquet is safe and that current practice can be continued.  (+info)

The value of late computed tomographic scanning in identification of vascular abnormalities after abdominal aortic aneurysm repair. (6/5349)

PURPOSE: The purpose of this study was to determine the prevalence of late arterial abnormalities after aortic aneurysm repair and thus to suggest a routine for postoperative radiologic follow-up examination and to establish reference criteria for endovascular repair. METHODS: Computed tomographic (CT) scan follow-up examination was obtained at 8 to 9 years after abdominal aortic aneurysm (AAA) repair on a cohort of patients enrolled in the Canadian Aneurysm Study. The original registry consisted of 680 patients who underwent repair of nonruptured AAA. When the request for CT scan follow-up examination was sent in 1994, 251 patients were alive and potentially available for CT scan follow-up examination and 94 patients agreed to undergo abdominal and thoracic CT scanning procedures. Each scan was interpreted independently by two vascular radiologists. RESULTS: For analysis, the aorta was divided into five defined segments and an aneurysm was defined as a more than 50% enlargement from the expected normal value as defined in the reporting standards for aneurysms. With this strict definition, 64.9% of patients had aneurysmal dilatation and the abnormality was considered as a possible indication for surgical repair in 13.8%. Of the 39 patients who underwent initial repair with a tube graft, 12 (30.8%) were found to have an iliac aneurysm and six of these aneurysms (15.4%) were of possible surgical significance. Graft dilatation was observed from the time of operation (median graft size of 18 mm) to a median size of 22 mm as measured by means of CT scanning at follow-up examination. Fluid or thrombus was seen around the graft in 28% of the cases, and bowel was believed to be intimately associated with the graft in 7%. CONCLUSION: Late follow-up CT scans after AAA repair often show vascular abnormalities. Most of these abnormalities are not clinically significant, but, in 13.8% of patients, the thoracic or abdominal aortic segment was aneurysmal and, in 15.4% of patients who underwent tube graft placement, one of the iliac arteries was significantly abnormal to warrant consideration for surgical repair. On the basis of these findings, a routine CT follow-up examination after 5 years is recommended. This study provides a population-based study for comparison with the results of endovascular repair.  (+info)

Immunohistochemical analysis of arterial wall cellular infiltration in Buerger's disease (endarteritis obliterans). (7/5349)

PURPOSE: The diagnosis of Buerger's disease has depended on clinical symptoms and angiographic findings, whereas pathologic findings are considered to be of secondary importance. Arteries from patients with Buerger's tissue were analyzed histologically, including immunophenotyping of the infiltrating cells, to elucidate the nature of Buerger's disease as a vasculitis. METHODS: Thirty-three specimens from nine patients, in whom Buerger's disease was diagnosed on the basis of our clinical and angiographic criteria between 1980 and 1995 at Nagoya University Hospital, were studied. Immunohistochemical studies were performed on paraffin-embedded tissue with a labeled streptoavidin-biotin method. RESULTS: The general architecture of vessel walls was well preserved regardless of the stage of disease, and cell infiltration was observed mainly in the thrombus and the intima. Among infiltrating cells, CD3(+) T cells greatly outnumbered CD20(+) B cells. CD68(+) macrophages or S-100(+) dendritic cells were detected, especially in the intima during acute and subacute stages. All cases except one showed infiltration by the human leukocyte antigen-D region (HLA-DR) antigen-bearing macrophages and dendritic cells in the intima. Immunoglobulins G, A, and M (IgG, IgA, IgM) and complement factors 3d and 4c (C3d, C4c) were deposited along the internal elastic lamina. CONCLUSION: Buerger's disease is strictly an endarteritis that is introduced by T-cell mediated cellular immunity and by B-cell mediated humoral immunity associated with activation of macrophages or dendritic cells in the intima.  (+info)

The intrarenal vascular lesions associated with primary antiphospholipid syndrome. (8/5349)

Even 10 yr after the identification of the antiphospholipid syndrome (APS), renal involvement in the course of APS is still relatively unrecognized, and is probably underestimated. The association of anticardiolipin antibodies and/or lupus anticoagulant with the development of a vaso-occlusive process involving numerous organs is now confirmed. In a multicenter study, 16 cases of "primary" APS (PAPS) were found and followed for 5 yr or more, all with renal biopsy. In all 16 cases of PAPS, there was a vascular nephropathy characterized by small vessel vaso-occlusive lesions associated with fibrous intimal hyperplasia of interlobular arteries (12 patients), recanalizing thrombi in arteries and arterioles (six patients), and focal cortical atrophy (10 patients). In combination, these led to progressive destruction of the kidney, accelerated by acute glomerular and arteriolar microangiopathy in five patients. Focal cortical atrophy is a distinctive lesion, present in 10 biopsies, and likely represents the histologic and functional renal analogue to the multiple cerebral infarcts detected on imaging studies. The clinical hallmark of this vascular nephropathy in PAPS is systemic hypertension, only variably associated with renal insufficiency, proteinuria, or hematuria. The ensemble of histologic renal lesions defined in this study should aid in the separation of the lesions found in cases of secondary APS, especially systemic lupus erythematosus, into those lesions related to APS and those related to the underlying disease.  (+info)

To date, there have only been limited data on the prevalence of LA thrombus detection among patients with AF on NOAC therapy. In a subgroup analysis of patients in the RELY (Randomized Evaluation of Long Term Anticoagulant Therapy) study, the rates of LA thrombus detection among patients undergoing TEE before cardioversion were 1.2% to 1.8% for patients on dabigatran (14). In the ARISTOLE (Apixaban for the Prevention of Stroke in Subjects With Atrial Fibrillation) study, TEE data were available in 86 patients on apixaban and none of these patients had LA thrombus (15). In an analysis of patients undergoing cardioversions or catheter ablation of AF in the ROCKET AF (Rivaroxaban Once Daily Oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation) study, no TEE data were collected to assess rates of LA thrombus detection among patients on rivaroxaban (16).. In our study, the rate of LA thrombus detection among patients on ...

Among 364 patients, 31 (8.5%) developed LVT. The mean age was 62 years, 75% were men, and mean LVEF was 46%. Patients developing LVT had increased heart rate, lower LVEF, impaired GLS, and more frequently had prior myocardial infarction. Variables associated with low values of EPI included, among others, LVEF, LV aneurysm, and GLS. EPI and LVT formation were significantly associated in the univariable model (OR = 1.87 (1.53-2.28), p , 0.001), and EPI showed an AUC of 0.90. After multivariable adjustments, EPI and LVT formation remained significantly associated (OR = 1.79 (1.42-2.27), p , 0.001). Patients with an EPI , 1.0 had a 23 times higher likelihood of LVT formation (OR = 23.41 (10.06-54.49), p , 0.001). EPI and LVT formation are strongly associated in patients with STEMI, with low values of EPI indicating a markedly increased probability of LVT formation ...
BioAssay record AID 444449 submitted by ChEMBL: Anticoagulant activity against Sprague-Dawley rat arterial thrombosis model induced by topical application of Fecl2.
Background-Selective inhibitors of cyclooxygenase-2 (COX-2) increase the risk of myocardial infarction and thrombotic events, but the responsible mechanisms are not fully understood. Methods and Results-We found that ferric chloride-induced arterial thrombus formation was significantly greater in COX-2 knockout (KO) compared to wild type (WT) mice. Cross-transfusion experiments excluded the likelihood that COX-2KO platelets, despite enhanced aggregation responses to collagen and thrombin, are responsible for increased arterial thrombus formation in COX-2KO mice. Importantly, we observed that COX-2 deletion decreased prostacyclin (PGI2) synthase and production, proliferator-activated receptor (PPAR)δ and sirtuin-1 (SIRT1) expression, with consequent increased upregulation of tissue factor (TF), the primary initiator of blood coagulation. Treatment of WT mice with a PGI2 receptor (IP) antagonist or a PPARδ antagonist, which predisposes to arterial thombosis, decreased SIRT1 expression and ...

Benedict, C.R.; Todd, J.; Pawashe, A.B.; Ezekowitz, M.D., 1995: Monoclonal antibody to tissue factor inhibits intravascular thrombosis without impairing extravascular hemostasis
Although there are a number of well-characterized genetic defects that lead to increased risk of thrombosis, little information is available on the relative importance of genetic factors in thrombosis risk in the general population. We performed a family-based study of the genetics of thrombosis in the Spanish population to assess the heritability of thrombosis and to identify the joint actions of genes on thrombosis risk and related quantitative hemostasis phenotypes. We examined 398 individuals in 21 extended pedigrees. Twelve pedigrees were ascertained through a proband with idiopathic thrombosis, and the remaining pedigrees were randomly ascertained. The heritability of thrombosis liability and the genetic correlations between thrombosis and each of the quantitative risk factors were estimated by means of a novel variance component method that used a multivariate threshold model. More than 60% of the variation in susceptibility to common thrombosis is attributable to genetic factors. Several ...
Platelets play an important role in the development of atherosclerosis and its thromboembolic complications.2 25 In thromboembolic disorders, the complex interplay between the vessel wall, platelets, and plasma proteins is strongly affected by local blood flow conditions.26 The goal of the present study was to investigate collagen-induced arterial thrombus formation in blood from groups of volunteers at risk to develop thrombotic disorders, such as habitual cigarette smokers and patients with severe peripheral atherosclerotic disease. The study was performed with a human ex vivo model of thrombogenesis6 7 at wall shear rates comparable to those encountered in medium-sized (650 s−1) and moderately stenosed (2600 s−1) arteries.. Thrombus formation in blood from habitual cigarette smokers was not enhanced after 10 hours of smoking abstinence. However, the smoking of a cigarette increased thrombus volume twofold at the highest arterial shear condition (2600 s−1). Thus, the thrombotic response ...
Left ventricular thrombus is a blood clot (thrombus) in the left ventricle of the heart. LVT is a common complication of acute myocardial infarction (AMI). Typically the clot is a mural thrombus, meaning it is on the wall of the ventricle. The primary risk of LVT is the occurrence of cardiac embolism, in which the thrombus detaches from the ventricular wall and travels through the circulation and blocks blood vessels. Blockage can be especially damaging in the heart or brain (stroke). LVT occurs most often during the first 2 weeks following AMI. AMI patients most at risk display the 3 characteristics of Virchows triad: The risk of LVT formation increases as infarction size increases. A larger infarction means a larger area of tissue injury, which may be akinetic or dyskinetic, resulting in stagnation of ventricular blood. Monocytes and macrophages play important roles in healing after myocardial infarction. With the absence of monocytes and macrophages, chances of LVT formation are very high. ...
The haemostatic system evolves to form a thrombus (clot) at the site of vascular injury to prevent the loss of blood. The response is rapid to limit bleeding and is regulated to prevent excessive clotting that can limit flow. Haemostasis involves complex interactions among multiple molecular and cellular components in the blood and vessel wall, as well as the influence of the flowing blood.. Understanding these processes has significant biomedical values. Improper regulation of thrombus generation can result in haemorrhage following impaired formation of a thrombus on disrupted vessels or thrombosis following inappropriate intravascular coagulation. These processes are involved in stroke (haemorrhagic or thrombotic), thrombotic complications associated with cancer, coronary infarction, and peripheral artery or vein thrombosis. The latter condition results in 250 000 hospitalizations a year in the USA, and the incidence will increase as the population ages. Furthermore, thrombus structure and ...
This study provides new data concerning the performance of current imaging strategies, as well as utility of a novel approach (predicated on a routine echo) for post-MI LV thrombus. There were several key findings. First, LV thrombus remains an important diagnostic issue in the current reperfusion era. Among the broad post-MI population studied, thrombus was present in 8% of all patients, including 15% of those with LAD infarction. Second, although generally associated with adverse remodeling, markedly depressed EF (≤30%) on echo occurred in only 12% of patients with thrombus, and only 18% had an LV aneurysm. Third, despite tailored imaging with uniform contrast administration, echo remained limited as a solitary strategy for post-MI thrombus. Noncontrast echo yielded a diagnostic sensitivity of 35% compared with the reference DE-CMR. Although use of contrast improved echo image quality and sensitivity (64%), one-third of DE-CMR-evidenced thrombi were missed. Fourth, thrombus was strongly ...
Arterial thrombosis is much less common than venous thrombosis, although it poses similar risks. The veins are responsible for taking blood and oxygen to different sections of the body. The blood is normally subject to higher pressure when it is travelling in the veins and may be moving more quickly. It is therefore less likely to clot in the arteries. Whereas venous thromboses normally lead to swelling and fluid congestion in an area, arterial thrombosis can lead to body tissue becoming starved of blood and oxygen. This can eventually lead to necrosis of the tissue. A thrombosis or embolism in the coronary artery can cause a heart attack. If blood supply to the brain is disrupted, the patient may suffer a stroke. ...

We examined the susceptibility of COX-2KO mice to arterial thrombosis, and using additional ex vivo and in vitro experiments, we elucidated the molecular mechanisms responsible for this phenomenon. We report here for the first time an intriguing link between prostacyclin, PPARδ, and SIRT1 that results in TF upregulation. In particular, we show a direct link between reduced PGI2 levels and accelerated thrombus formation that implicates TF as a key player. Increased systemic and local TF is identified as responsible for the propensity for thrombosis observed in mice in which COX-2 activity is impaired. Deletion/inhibition of COX-2 increased thrombus formation after arterial injury via mechanism(s) that are apparently independent of platelet aggregability but require downregulation of SIRT1 expression. Previous evidence indicates that inhibition, deletion, or inactivation of COX-2 favors the occurrence of a prothrombotic state,22-26 but the mechanisms underlying this effect were not fully ...

Methods and Results-Using recombinant proteins and a murine model, we demonstrated that an ADAMTS13 variant truncated after either the eighth thrombospondin type 1 repeat or the spacer domain inhibits ferric chloride-induced arterial thrombosis in ADAMTS13−/− mice with efficacy similar to that of full-length ADAMTS13. The results obtained from monitoring thrombus formation in carotid and mesenteric arteries were highly concordant. Further analyses by site-directed mutagenesis and human monoclonal antibody inhibition assay revealed that the Cys-rich and spacer domains of ADAMTS13, particularly the amino acid residues between Arg559 and Glu664 in the spacer domain, may be critical for modulation of arterial thrombosis in vivo. Finally, the thrombosis-modulating function of ADAMTS13 and variants/mutants was highly correlated with the von Willebrand factor-cleavage activity under fluid shear stress.. ...
TY - JOUR. T1 - Thrombin-targeted liposomes establish a sustained localized anticlotting barrier against acute thrombosis. AU - Palekar, Rohun U.. AU - Myerson, Jacob W.. AU - Schlesinger, Paul H.. AU - Sadler, J. Evan. AU - Pan, Hua. AU - Wickline, Samuel A.. PY - 2013/11/4. Y1 - 2013/11/4. N2 - The goal of the present work was to design and test an acute-use nanoparticle-based antithrombotic agent that exhibits sustained local inhibition of thrombin without requiring a systemic anticoagulant effect to function against acute arterial thrombosis. To demonstrate proof of concept, we functionalized the surface of liposomes with multiple copies of the direct thrombin inhibitor, d-phenylalanyl-l-prolyl-l-arginyl-chloromethyl ketone (PPACK), which exhibits high affinity for thrombin as a free agent but manifests too rapid clearance in vivo to be effective alone. The PPACK-liposomes were formulated as single unilamellar vesicles, with a diameter of 170.78 ± 10.59 nm and a near neutral charge. In ...
Thrombosis is the name given to the formation of blood clots in an area where clotting is not a medical necessity. When the body is injured in any way, the blood may need to clot at the site of the wound to help to prevent blood loss and promote healing. Platelets and Fibrin in the blood can bond together to produce a clot which protects the affected area. However, clots can sometimes form within blood vessels when they are not medically required. This normally happens because of a change in the speed of the blood flow or the core content of the blood.. Thrombosis can affect the flow of the blood around the body. Clots can partially or fully block a blood vessel, meaning that blood cannot circulate in the normal way. This is referred to as an embolism. Unexplained pain, heat or swelling in one area of the leg may suggest deep vein thrombosis.. Thrombosis is more likely to occur in people who are unable to move freely, for whatever reason; including those maintaining a sedentary lifestyle, ...
Background. Hypercoagulable disorders can lead to deep vein thrombosis (DVT), arterial thrombosis or embolization, and early or recurrent bypass graft failure. The purpose of this study was to identify whether diabetes increased the likelihood of heparin-induced platelet factor 4 antibodies in at risk vascular patients. Methods. We reviewed clinical data on 300 consecutive patients. A hypercoagulable workup was performed if patients presented with (1) early bypass/graft thrombosis (,30 days), (2) multiple bypass/graft thrombosis, and (3) a history of DVT, pulmonary embolus (PE), or native vessel thrombosis. Relevant clinical variables were analyzed and compared between patients with diabetes (DM) and without diabetes (nDM). Results. 85 patients (47 women; age 53 16 years, range 16-82 years) had one of the defined conditions and underwent a hypercoagulable evaluation. Screening was done in 4.7% of patients with early bypass graft thrombosis, 60% of patients were screened because of multiple ...

The data on increased stent thrombosis rates in bare metal stents may be one of the surprises of the DAPT trial because, in 2006, when the first concerns over increased stent thrombosis rates in DES surfaced, a large number of clinicians reverted to the earlier bare metal devices. Dr. Kereiakes will be presenting a more detailed analysis of these data in a Tuesday presentation, but this observation mirrors some of the findings in the ZEUS study, reported on previously by Angioplasty.Org.. Although the DAPT trial seems to give a green light to extended duration of DAPT therapy, many clinicians have stated that one size fits all medicine cannot be invoked in these situations, that a more individualized approach is required. Some patients are less at risk for stent thrombosis, or they may need surgery requiring cessation of DAPT therapy. Recent studies, with newer second generation stents, have shown no adverse effects from early interruption of DAPT therapy.. In fact, one very important set of ...

Results: SLE with a history of thrombosis in the past 5 years presented with 5.5 and 2.2-fold higher median PC4d (27 [IQR: 8-79 net MFI] vs 5 [IQR: 2-14 net MFI] net MFI) and EC4d (19 [IQR: 9-59 net MFI] vs 9 [IQR: 6-19] net MFI]) levels, respectively, than SLE without thrombotic events (p,0.001; n=148). Low C3 (OR=10.5 [CI 95%: 2.6-42.0]), low C4 (OR=3.5 [CI 95%: 1.1-11.1), abnormal PC4d (OR=19.0 [CI 95%: 3.7-96.4; n=148), EC4d (OR=4.0 [CI95%: 1.3-11.8]), and LAC (OR=5.3 [CI 95%: 1.1-24.5; n=144) were all significantly associated with thrombosis (p,0.035). Prednisone was also associated with thrombosis (OR=3.2 [CI95%: 1.1-8.9]) (p=0.037). Multivariate analysis revealed that low C3, abnormal PC4d and LAC were all independently and significantly associated with thrombosis (p,0.027) and the cumulative presence of these abnormalities resulted in higher likelihood of thrombosis (OR range: 81.9 CI95%: 9.7-688.5; n=144) (p,0.001) (Figure). These results remained significant after adjusting for ...

Methods: We performed a retrospective study with collection of data from January 2011 to September 2016. Medical records of patients were reviewed for: demographic data, cardiovascular risk factors or any known prothrombotic predisposing condition, clinical presentation, vessel of embolism, localization of aortic thrombus, treatment of AMT and symptoms, follow-up, and computed tomography scan imaging findings.. Results: A total of 8 patients were included in the study. Mean age was 54.7 ± 11.5 years, with male/female ratio 3:1. Four (50%) patients had AMT at the arch or descending aorta, 3 (37.5%) patients in the infrarenal sector, and the remaining in the visceral aorta. All but one patient received anticoagulation alone for the aortic thrombus. Patient with femoral thromboembolectomy died in the early postoperative time due to severe massive embolism. Median follow-up was 23 months (range, 1-50). Five out of seven patients showed complete aortic thrombus resolution in imaging follow up. None ...
Venal thrombosis is a highly dangerous type of blood clots. Blood clots are sometimes necessary, but venal thrombosis puts your life at risk! See why! Most of the time, blood clots are a good thing. When you get injured, blood is needed to solidify and clump in place to help stop bleeding. But sometimes clots arise when they are not needed, which can mean a problem, especially if they form in the deep veins near the muscles. When blood clots form in this deeper system, it can be painful and extremely dangerous.. Actually, this type of clot is called deep venal thrombosis or DVT. Deep venous thrombosis is like barricades in the blood roads: they cause traffic jams in the circulation and prevent blood flow to keep the system functioning. Things can be even more serious if a DVT separates from its place of origin and travels to the lungs. It then becomes a pulmonary embolism (PE), a clot that prevents these vital organs from receiving the oxygen and blood they need. This can damage the lungs and ...
Cerebral microembolic signal (MES) is an independent predictor of stroke risk and prognosis. The objective of this study is to assess the effects of apixaban, as a representative of the novel oral anticoagulant class, on a rabbit model of cerebral MES. A clinical transcranial Doppler ultrasound instrument was used to assess MESs in the middle cerebral artery in a 30% FeCl3-induced carotid arterial thrombosis model in male New Zealand White rabbits. Ascending doses of apixaban were evaluated as monotherapy and in combination with aspirin on both arterial thrombosis and MES. Pharmacokinetic and pharmacodynamic responses were also evaluated. The effective dose for 50% inhibition (ED50) of thrombus formation for monotherapy was 0.04 mg/kg per hour apixaban, i.v. (0.03 μM plasma exposure) for the integrated blood flow, 0.13 mg/kg per hour apixaban (0.10 μM plasma exposure) for thrombus weight, and 0.03 mg/kg per hour apixaban (0.02 μM plasma exposure) for MES. Dual treatment with aspirin (5 mg/kg, ...
Therefore, univariate analysis showed that thrombus size, presence of slowed flow, and fibrin composition were associated with a positive angiogram. Fitting of a logistic regression model incorporating all three variables in 26 specimens confirmed the abovementioned influence of thrombus size on the outcome of arteriography. Neither fibrin composition nor slowed flow added independent information on the outcome of arteriography, suggesting that their contribution is already shared by the variable thrombus size ...
A thrombosis filter configured for placement within a blood vessel lumen. The thrombosis filter of the present invention includes a body element, a plurality of struts, and a surface treatment. The surface treatment, comprised in part of an anti-proliferative or anti-angiogenic drug, is applied to portions of the thrombosis filter in order to regulate neointimal growth around the thrombosis filter and its anchor elements. The thrombosis filter may further contain a first and a second surface treatment layer. The first surface treatment layer possesses endothelial cell growth enhancing properties, while the second surface treatment layer includes the anti-proliferative or anti-angiogenic drug. The surface treatment may alternatively be applied to a substrate, which in turn is applied to the filter.
Carlos V. Serrano, Pedro H. M. Cellia, Bruna R. Scarpa, Priscilla Teixeira Céo Frisso, Otavio R. Coelho, Alvaro Avezum Junior. ABSTRACT. Recent evidence has described beneficial clinical effects among patients with stable coronary artery disease (CAD), peripheral artery disease (PAD), and/or stroke when low-dose rivaroxaban (anti-factor Xa) was added to aspirin. A decrease on atherothrombotic events was observed, in part, by optimization of vascular protection. While the function of platelets is well recognized, substantiation is being composed on the role of coagulation factors to the developments of both atherosclerosis and atherothrombosis. Coagulation factors participate importantly on thrombus formation, meaning fibrin materialization and platelet activation and aggregation. In addition, these factors facilitate numerous pathophysiologic mechanisms through activation of protease‐activated‐receptors (PARs). Consequently, the association of anticoagulant to antiplatelet has obtained ...

Red blood cells (RBCs) influence rheology, and release ADP, ATP, and nitric oxide, suggesting a role for RBCs in hemostasis and thrombosis. Here, we provide evidence for a significant contribution of RBCs to thrombus formation. Anemic mice showed enhanced occlusion times upon injury of the carotid artery. A small population of RBCs was located to platelet thrombi and enhanced platelet activation by a direct cell contact via the FasL/FasR (CD95) pathway known to induce apoptosis. Activation of platelets in the presence of RBCs led to platelet FasL exposure that activated FasR on RBCs responsible for externalization of phosphatidylserine (PS) on the RBC membrane. Inhibition or genetic deletion of either FasL or FasR resulted in reduced PS exposure of RBCs and platelets, decreased thrombin generation, and reduced thrombus formation in vitro and protection against arterial thrombosis in vivo. Direct cell contacts between platelets and RBCs via FasL/FasR were shown after ligation of the inferior vena ...
Ischemic stroke is primarily caused by thromboembolic occlusion of a major artery that supplies the brain (9). When emboli or thrombi in situ occlude cerebral arteries, circulating platelets are rapidly recruited to the site of the occluded vessels (14). Platelets, along with thrombin and fibrin resulting from tissue factor-activated blood coagulation, are the primary contributors to thrombus development at the site of the occluded artery (14, 15). Concomitantly, occlusion of a major cerebral artery triggers development of secondary thrombosis in downstream microvessels, which causes dysfunction of cerebral endothelial cells, pericytes, and astrocytes and leads to disruption of the blood-brain barrier (BBB) and ischemic cell damage (16-19). The evolution of downstream microvascular thrombosis is heterogeneous and continues for hours and is highly associated with the progression of ischemic neuronal death from reversible to irreversible damage (14, 16-18). Thus, the primary goal for treatment of ...

Dronedarone has been associated with a reduced number of first hospitalisation due to acute coronary syndromes. Whether this is only due to the reduction in ventricular heart rate and blood pressure or whether other effects of dronedarone may be involved is currently elusive. This study was designed to investigate the role of dronedarone in arterial thrombus formation. C57Bl/6 mice were treated with dronedarone and arterial thrombosis was investigated using a mouse photochemical injury model. Dronedarone inhibited carotid artery thrombus formation in vivo (P , 0.05). Thrombin- and collagen-induced platelet aggregation was impaired in dronedarone-treated mice (P , 0.05), and expression of plasminogen activator inhibitor-1 (PAI1), an inhibitor of the fibrinolytic system, was reduced in the arterial wall (P , 0.05). In contrast, the level of tissue factor (TF), the main trigger of the coagulation cascade, and that of its physiological inhibitor, TF pathway inhibitor, did not differ. Similarly, ...

Fibrinolysis is the physiological breakdown of blood clots by enzymes such as plasmin. Organisation: following the thrombotic event, residual vascular thrombus will be re-organised histologically with several possible outcomes. For an occlusive thrombus (defined as thrombosis within a small vessel that leads to complete occlusion), wound healing will reorganise the occlusive thrombus into collagenous scar tissue, where the scar tissue will either permanently obstruct the vessel, or contract down with myofibroblastic activity to unblock the lumen. For a mural thrombus (defined as a thrombus in a large vessel that restricts the blood flow but does not occlude completely), histological reorganisation of the thrombus does not occur via the classic wound healing mechanism. Instead, the platelet-derived growth factor degranulated by the clotted platelets will attract a layer of smooth muscle cells to cover the clot, and this layer of mural smooth muscle will be vascularised by the blood inside the ...
Objective: To determine whether very low doses of warfarin are useful in thrombosis prophylaxis in patients with central venous catheters.. Design: Patients at risk for thrombosis associated with chronic indwelling central venous catheters were prospectively and randomly assigned to receive or not to receive 1 mg of warfarin, beginning 3 days before catheter insertion and continuing for 90 days. Subclavian, innominate, and superior vena cava venograms were done at onset of thrombosis symptoms or after 90 days in the study.. Results: One hundred twenty-one patients entered the study, and 82 patients completed the study. Of 42 patients completing the study while receiving warfarin, 4 had venogram-proven thrombosis. All 4 had symptoms from thrombosis. Of 40 patients completing the study while not receiving warfarin, 15 had venogram-proven thrombosis, and 10 had symptoms from thrombosis (P , 0.001). There were no measurable changes in the coagulation values assayed due to this warfarin dose, except ...

Red blood cells (RBCs) demonstrate procoagulant properties in vitro, and elevated hematocrit is associated with reduced bleeding and increased thrombosis risk in humans. These observations suggest RBCs contribute to thrombus formation. However, effects of RBCs on thrombosis are difficult to assess because humans and mice with elevated hematocrit typically have co-existing pathologies. Using an experimental model of elevated hematocrit in healthy mice, we measured effects of hematocrit in two in vivo clot formation models. We also assessed thrombin generation, platelet-thrombus interactions, and platelet accumulation in thrombi ex vivo, in vitro, and in silico. Compared to controls, mice with elevated hematocrit (RBCHIGH) formed thrombi at a faster rate and had a shortened vessel occlusion time. Thrombi in control and RBCHIGH mice did not differ in size or fibrin content, and there was no difference in levels of circulating thrombin-antithrombin complexes. In vitro, increasing the hematocrit ...
Claire McLintock, a New Zealand representative on the governing council of the International Society on Thrombosis and Haemostasis (ISTH), hopes the organisations inaugural World Thrombosis Day will raise awareness of a massive killer she describes as a poor relation to some other disorders..

A number of risk factors for stent thrombosis have been identified by previous investigators. Persistent dissection, longer stent length, and final lumen diameter within the stent were identified as independent multivariable predictors of stent thrombosis in a meta-analysis of 6,186 patients enrolled in six major clinical trials of coronary stenting (17). Other studies have identified balloon size ≤2.5 mm, bail-out situations, unstable angina or acute MI (15), ejection fraction, use of a combination of different stents, postprocedural dissections, and slow flow (16)as predictive of stent thrombosis.. Multivariate analysis of correlates of stent thrombosis is difficult to perform in even a study as large as this because of the low incidence of the primary end point. A common method of avoiding over-fitting is bootstrap model selection. It involves creating random data sets from the patient population, selecting correlates with stepwise model selection for each bootstrap sample, and counting the ...

N2 - Platelet dysfunction, oxidative stress and dyslipidemia are important contributors to pro-thrombotic progression particularly in obese and hyper-cholesterolemic populations. Becoming an increasingly widespread endemic, obesity causes a dysfunction in the metabolic system by initiating endothelial dysfunction; increasing free radical production; lipid peroxidation; platelet hyperactivity and aggregation; thereby accelerating thrombogenesis. In the event of increased free radical generation under pro-thrombotic conditions, antioxidants act as scavengers in reducing physiological oxidative stress; free radicalmediated thrombosis and hemostatic ...
Platelet aggregation plays a central role in the development of the occlusive thrombus responsible for acute coronary occlusion in people with ACS. People with diabetes have a pro-thrombotic state due to dysfunctional and hyperactive platelets, endothelial dysfunction, elevated coagulation factors and decreased fibrinolysis (32). Increased platelet activity is due to multiple metabolic and cellular factors associated with diabetes that include endothelial dysfunction, the impact of hyperglycemia and deficient insulin action (32).. Diabetes is associated with an increased incidence of recurrent atherothrombotic events (33), including stent thrombosis (34). Anti-platelet therapy has been shown to reduce atherothrombotic events in people with ACS, both during the acute phase and in the longer term. The beneficial effect of ASA has been shown in multiple clinical trials in patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) and ST-segment elevation MI (STEMI). The ...

We report a case of recurrent right atrial thrombus due to Behçet disease despite continued anticoagulation therapy. The thrombus disappeared after the initiation of immunosuppressive therapy. To avoid a progression to thrombus or cardiac dysfunction in this recurrent case, the early identification of cardiac involvement of Behçet disease using echocardiography and/or cardiac magnetic resonance imaging might be important. Combined immunosuppressive therapy with prednisone and cyclophosphamide might be needed to treat recurrent thrombosis due to Behçet disease.. AB - Behçet disease is a ...
Platelets play a major role in the complex interactions involved in blood coagulation via multiple mechanisms. As reported in this issue, Schoergenhofer et al. tested the hypothesis that platelet inhibition by prasugrel, a potent platelet P2Y12 ADP receptor antagonist, attenuates the effect of lipopolysaccharide (LPS) on the blood coagulation system in healthy human subjects. LPS, a bacterial product with potent pro-inflammatory and pro-thrombotic effects, plays a central role in sepsis. It activates monocytes and endothelial cells via Toll-like receptor (TLR) 4 and other TLRs to stimulate production of TF and other pro-coagulant molecules, chemokines and cytokines. Treatment with prasugrel did not decrease biomarkers of coagulaion. A better understanding of the relative roles of platelet and coagulation mechanisms in triggering the pro-thrombotic state may lead to more effective antithrombotic strategies. ...

METHODS AND RESULTS: PI3K/p110α was inhibited by treatment with the small molecule inhibitor PIK75 or a specific siRNA. Arterial thrombosis, neointima formation, and re-endothelialization were studied in a murine carotid artery injury model. Proliferation and migration of human vascular smooth muscle cell (VSMC) and endothelial cell (EC) were assessed by cell number and Boyden chamber, respectively. Endothelial senescence was evaluated by the β-galactosidase assay, endothelial dysfunction by organ chambers for isometric tension. Arterial thrombus formation was delayed in mice treated with PIK75 when compared with controls. PIK75 impaired arterial expression and activity of tissue factor (TF) and plasminogen activator inhibitor-1 (PAI-1); in contrast, plasma clotting and platelet aggregation did not differ. In VSMC and EC, PIK75 inhibited expression and activity of TF and PAI-1. These effects occurred at the transcriptional level via the RhoA signalling cascade and the transcription factor ...

Various factors at multiple levels- donor, recipient, surgical and therapy-related, come into play in contributing to this risk. While early detection and intervention are keys in limiting the adverse effect of graft thrombosis on graft survival, preventative strategies have the most to offer in reducing morbidity related to this devastating complication. This article reviews the epidemiology, risk factors, diagnostic and therapeutic modalities to assist the clinician in taking care of children who are in the process of receiving renal transplants. ...
A venous thrombosis or phlebothrombosis is a blood clot (thrombus) that forms within a vein. Thrombosis is a term for a blood clot occurring inside a blood vessel. A classical venous thrombosis is deep vein thrombosis (DVT), which can break off, and become a life-threatening pulmonary embolism (PE). The disease process venous thromboembolism (abbreviated as VTE or DVT/PE) can refer to DVT and/or PE.. ...
Staphylococcus aureus is one of the most common causes of community- and hospital-acquired infections. Many common diseases caused by S. aureus include infectious endocarditis, osteomyelitis, septic arthritis, pneumonia and septicemia. The recent surge in methicillin resistant S. aureus (64.4% of cases) and continued appearance of vancomycin resistant S. aureus highlights the need to develop a clearer understanding of the pathogenesis and infective mechanisms of the bacterium. In the initial stages of infection, S. aureus adheres to surface tissues. Once inside the bloodstream, the bacterium can be carried to any location in the body and promote new infections. The overall goal of this project is to understand how bacteria incorporate into growing thrombi and the effects of the bacterial presence on thrombus formation. The first part of my research quantifies bacterial incorporation into growing thrombi both at the surface and in the aggregate. Our results demonstrate that the fibrinogen ...
Fibrinolysis is the physiological breakdown of blood clots by enzymes such as plasmin. Organisation: following the thrombotic event, residual vascular thrombus will be re-organised histologically with several possible outcomes. For an occlusive thrombus (defined as thrombosis within a small vessel that leads to complete occlusion), wound healing will reorganise the occlusive thrombus into collagenous scar tissue, where the scar tissue will either permanently obstruct the vessel, or contract down with myofibroblastic activity to unblock the lumen. For a mural thrombus (defined as a thrombus in a large vessel that restricts the blood flow but does not occlude completely), histological reorganisation of the thrombus does not occur via the classic wound healing mechanism. Instead, the platelet-derived growth factor degranulated by the clotted platelets will attract a layer of smooth muscle cells to cover the clot, and this layer of mural smooth muscle will be vascularised by the blood inside the ...
Because of its high sensitivity and reproducibility, the FeCl3‐induced arterial thrombosis mouse model is widely used to study molecular mechanisms as well as the efficacy of antithrombotic agents
Dual antiplatelet therapy may be effective for the prophylaxis of recurrent of arterial thrombosis in patients with antiphospholipid syndrome.
Thrombosis is a peer-reviewed, Open Access journal that publishes original research articles, review articles, and clinical studies related to all aspects of thrombosis.
In disseminated cancer, hypercoagulability is due to secretion of thrombogenic factors by tumour necrotic cells. either it forms in the rapid arterial and cardiac circulation, or in the slow-moving flow in veins. Sudden death may occur due to thrombosis of the coronary artery. The mass is also known as a thrombus. When DVT and pulmonary embolism occur together, its called venous thromboembolism (VTE).

deep vein thrombosis occurs when a blood clot forms in one or more veins located in depth allinside your body. These blood clots usually develop in the legs, but can occur at several points. The blood forms a clot when it does not circulate normally. Some signs and symptoms include swelling, pain, cramps, laffected area is warmer than the surrounding areas and you may notice a change in the color of the skin around the affected area. Most people have no symptoms, making it difficult to diagnose the problem at an early stage. The thrombosis can be very dangerous, especially if the coaugulo off and through the blood stream, reaches the lung resulting in pulmonary embolism. Some of the factors, in addition to genetics, can being open, most this type of problems, as lobesity, pregnancy, some types of cancer, heart failure, vein problems , the smoke, l taking birth control pills and the family history. Once diagnosed by a doctor deep venous thrombosis, an appropriate treatment will be prescribed. ...

Methods-In this retrospective cross-sectional study, patients undergoing stroke workup were imaged with MRI and IPH detection. Seven hundred twenty-six carotid-brain image pairs were analyzed after excluding vessels with noncarotid plaque stroke sources (420) and occlusions (7) or near-occlusions (3). Carotid imaging characteristics were recorded, including percent diameter and mm stenosis, plaque thickness, ulceration, intraluminal thrombus, and IPH. Clinical confounders were recorded, and a multivariable logistic regression model was fitted. Backward elimination was used to determine essential carotid-source stroke predictors with a threshold 2-sided P,0.10. Receiver operating characteristic analysis was performed to determine discriminatory value.. ...
Background Survivors of anterior MI are in increased risk for heart stroke with predilection to create ventricular thrombus. buy KRN 633 therapy. Within 4 years, 169 sufferers (5.7%) were admitted with an ischemic buy KRN 633 stroke, fifty percent which occurred within 1-calendar year post-MI. There is no factor in heart stroke price between anterior and non-anterior MI sufferers. The usage of warfarin up to 3 months was not connected with stroke security after anterior MI (threat proportion [HR], 0.68; 95% self-confidence period [CI], 0.37C1.26). The usage of angiotensin-converting-enzyme inhibitors (HR, 0.65; 95% CI, 0.44C0.95) and beta-blockers (HR, 0.60; 95% CI, 0.41C0.87) were connected with a significant reduction in heart stroke risk. There is no factor in bleeding-related hospitalizations in individuals who utilized warfarin for 3 months post-MI. Summary Many professionals still look at a huge buy KRN 633 anterior-wall MI as risky for potential LV thrombus development and heart stroke. ...
Are there differences between varicose veins and thrombosis?. Varicose veins are conditions in the veins that not only occur in older people, but young people can also have them. The problem is that with the elderly, it can be difficult due to the weakening of the internal organs. The fact that a person has varicose veins does not mean that he or she will necessarily develop thrombosis. However, if other factors are incorporated into this problem, the adult may have this defect.. Therefore, it can be said that varicose veins can present themselves from an early age, which can evolve into thrombosis, depending on certain factors.. If an older person already has thrombosis, special care is needed so that the condition does not worsen and endanger the persons well-being. Many relatives of older adults, because of the special attention required, decide to place the older person in an assisted living Rosarito facility, where they can get the necessary care with the support of doctors.. Returning to ...
Left atrial ball-shaped masses may be thrombi, vegetations or tumor. Treatment may be different in each of these entities, and includes antibiotics, anticoagulants or surgery (4,5).. Left atrial ball thrombus in the absence of mitral valve disease has been reported even less frequently with most of the patients having been described as not being adequately anticoagulated for their atrial fibrillation(3,6).. Although it may not be possible to know the precise mechanism by which the thrombus ball was formed, it is reasonable to assume an origin from a smaller mural thrombus created secondary to chronic blood stagnation(3).It gradually enlarges and forms projecting mass that remains attached to the atrial wall by a pedicle(7).During thrombus development and subsequent morphologic changes,it is very likely that the patient may experience transient embolisms or strokes(7,8).. Transthoracic and transesophageal echocardiography are the procedures of choice for the diagnosis of cardiac mass involving ...
