BACKGROUND AND OBJECTIVES: Thrombosis is an uncommon disorder in children. Patients with slowflow vascular malformations have higher risk of developing localized intravascular coagulation, which is closely related to the presence of thrombotic events. These episodes cause pain, can be recurrent and determine a clear deterioration in the quality of life. Moreover, serious complications such as pulmonary thromboembolism and eventually death have been described. The aim of the present study is to identify clinical and laboratory risk factors associated with thrombotic events in pediatric patients with vascular malformations...

The nephrotic syndrome is characterized by the loss of many proteins, via the urinary system. It exceeds the bodies compensatory abilities and results in abnormalities in blood clotting system, particularly due to antithrombin deficiency. It significantly increases the risk of thromboembolic complications. A loss of erythropoietin and transferrin leads to anemia. Polycythemia is a rarely reported phenomenon. The case describes a 20-years old patient with massive nephrotic syndrome and polycythemia, complicated by a pulmonary embolism...

Chemokine-like factor 1 (CKLF1) is a newly cloned chemotactic cytokine with CCR4 being its functional receptor. Recent evidence demonstrates a role of CKLF1 in arthritis. The aim of this study was to quantify the expression of CKLF1 as well as assess the correlation between CKLF1 and plasma acute-phase markers. Synovium was obtained from 16 osteoarthritis (OA), 15 rheumatoid arthritis (RA) and 10 ankylosing spondylitis (AS) patients undergoing total joint arthroplasty, with other 11 patients treated for meniscal tears during sport accidents serving as normal controls...

We report a 37-year-old pregnant woman with paroxysmal nocturnal hemoglobinuria (PNH) treated with eculizumab. She had been diagnosed with PNH-aplastic anemia at age 19 years, and started to receive eculizumab at age 35 years. Thereafter, she had no hemolytic attacks. She became pregnant 2 years later, and treatment with eculizumab was continued. During her pregnancy, she showed no exacerbation of hemolysis. She delivered a girl by Caesarean section at 37 weeks and 3 days of gestation. Postpartum, anticoagulant therapy was started...

OBJECTIVES: It is standard practice for diagnostic tests to be evaluated against gold standards in isolation. In routine clinical practice, however, it is commonplace for multiple tests to be used before making definitive diagnoses. This article describes a meta-analytic modeling framework developed to estimate the accuracy of the combination of two diagnostic tests, accounting for the likely nonindependence of the tests. METHODS: A novel multicomponent framework was developed to synthesize information available on different parameters in the model...

OBJECTIVES: To investigate the importance of accounting for potential performance dependency when evaluating the cost-effectiveness of two diagnostic tests used in combination. METHODS: Two meta-analysis models were fitted to estimate the diagnostic accuracy of Wells score and Ddimer in combination. The first model assumes that the two tests perform independently of one another; thus, two separate meta-analyses were fitted to the Ddimer and Wells score data and then combined...

Proinflammatory components are present in abdominal aortic aneurysm (AAA). Circulating monocytes display heterogeneity, and three subsets have been identified, based on the differential expression for CD14 and CD16 receptors: CD14(+)CD16(−), classical, CD14(+)CD16(+), intermediate and CD14(dim)CD16(+), non-classical monocytes. Increased proinflammatory CD16+ monocytes with high expression of CD143 are present in CKD patients. D-dimer is increased in AAA patients, and might contribute to the pro-inflammatory response associated to circulating monocytes...

AIM: Atrial fibrillation (AF), the most frequent arrhythmia, is a major independent cardiovascular (CV) risk factor, especially in elderly patients. The interest of Ddimer (DD) measurement for predicting CV risk has been suggested in some subgroups of patients with AF but little is known about the negative prognostic value of DD measurement. The primary aim was to assess whether DD measurement and monitoring could predict the occurrence of subsequent CV events, defined as MI, stroke or transient ischemic attack and arterial embolic events...

BACKGROUND: A reliable, animal model of massive, totally occlusive, pulmonary embolism (PE) is lacking. OBJECTIVES: To design an animal model of totally occlusive PE and to challenge the model by a plasminogen activator. METHODS: In eight anaesthetized pigs (approximately 90 kg) a massive preformed autologous thrombus was injected into the caval vein. One animal was autopsied to assess the extent of injected clot, whereas in the other animals extracorporeal life support (ECLS) was initiated and continued for three hours...

A relationship between Central Nervous System and coagulation has been known since the work by Goodnight et al5. When an encephalic injury occurs tissue damage causes the release of thromboplastin-related products, mainly the Tissular Factor. This release produces an activation of the coagulation system specially through its extrinsic path. With this physiopathologic basis we attempt to improve the knowledge of this relation by performing a prospective study at the Intensive Care Unit of our Hospital. The study included 67 patients with cranioencephalic trauma alone, with an average Glasgow coma scale score of 10 and a control group consisting of 40 healthy subjects...

A 26-year-old pregnant woman was diagnosed as having both lupus anticoagulant (LA) and anticardiolipin antibody (ACA). Her previous pregnancy ended in intrauterine fetal death at 27 weeks' gestation. During the present pregnancy she was treated with aspirin, dipiridamole, predonisolone, and heparin. At 24 weeks, fetal growth became retarded, accompanied by markedly decreased activities of AT-III, protein C, plasminogen and alpha 2-plasmin inhibitor. Supplement of human AT-III led both to prolongation of the gestational period and improvement of fetal growth...

An overestimation of the plasminogen concentration occurs in patients with elevated levels of fibrin degradation products (fdp) and/or fibrinogen, when using assays based on the activation of plasminogen by streptokinase (Sk) followed by the hydrolysis of a synthetic chromogenic substrate. This source of error could be overcome by addition of fibrinogen in excess to the plasminogen assay thereby obtaining maximum stimulation of the Sk-plasminogen complex. The late degradation products of fibrinogen and fibrin, Dcate and Ddimer, respectively, had no potentiating effect on the Sk-plasminogen complex...

Severe microangiopathy resembling thrombotic thrombocytopenic purpura (TTP) has been reported as a complication of acute graft-versus-host disease (aGvHD) in patients receiving cyclosporin (CsA) prophylaxis following allogeneic BMT. In order to analyze the pathophysiological events involved in microangiopathy, a prospective study comparing release of von Willebrand Factor (vWF), t-PA and PAI, as well as TNF alpha and further coagulation parameters was performed in 32 patients. Endothelial damage as the central lesion was confirmed by the close association of vWF and t-PA:Antigen with severity of microangiopathy...
