: An adequate hemostatic balance is mandatory to get successful pregnancy. Obstetric complications, such as recurrent pregnancy loss (RPL), might be due to an impairment of placental perfusion possibly related to an underlying prothrombotic status. In this study, we used the global coagulation assay, calibrated automated thrombography and traditional coagulation assay to search for a possible underlying hypercoagulable status in women with history of RPL compared with uneventful pregnancy women. Thrombin generation, Fibrinogen, factor VIII (FVIII), Plasminogen Activator Inhibitor-1 (PAI-1) and von Willebrand factor levels were analyzed in 92 not pregnant unexplained RPL and 64 uneventful pregnancy women...

: Risk for thrombotic events with factor IX replacement therapy in patients with haemophilia B remains a concern for patients, those who treat them, and regulatory agencies, based on experience with early use of prothrombin complex concentrates. The current post hoc analysis assessed the incidence of thrombotic events and changes in prothrombin fragment 1 + 2, thrombin-antithrombin complex, and D-dimer in 221 patients with haemophilia B who received nonacog alfa in clinical studies. Thrombotic event and coagulation marker data were collected from 8 interventional studies utilizing on-demand, prophylactic, and preventive regimens in patients with haemophilia B...

: Acquired hemophilia A (AHA) which presents with spontaneous severe intramuscular, mucosal and/or subcutaneous bleeding is a rare bleeding disorder. Even 50% of AHA patients are defined as idiopathic; 10% of cases are related with malignancy. Here, we present a case of AHA in a 43-year-old lady who was diagnosed with malignancy and venous thromboembolism on vena cava 2 years ago. To the best of our knowledge, this is the first report in literature presented with both acquired hemophilia and thrombosis associated with malignancy...

: Diagnosis of factor XIII (FXIII) deficiency (FXIIID) as a rare bleeding disorder is a challenge worldwide. Thus, in the present study, we used different methods including two molecular methods for detection of FXIIID. This study was conducted on individuals suspected to FXIIID. All individuals were checked by two routinely used methods of clot solubility test in Iran and two other clot solubility tests as well as FXIII activity and antigen assays. Molecular analysis was performed by PCR-restriction fragment length polymorphism (PCR-RFLP) and tetra-primer amplification refractory mutation system (T-ARMS)-PCR for only FXIIID mutation in southeast Iran (p...

: The objective of the study is to perform a cost comparison of 1 year of oral anticoagulation management with warfarin vs. hypothetical rivaroxaban (RRX) in thrombotic primary antiphospholipid syndrome. Longitudinal study on 20 primary antiphospholipid syndrome patients followed-up for 1 year after anticoagulation stabilisation with warfarin: a dedicated software calculated number of clinic visits, time in therapeutic range and warfarin consumption for each patient; for RRX, we considered a visit every 3 months (baseline done in hospital before attending anticoagulant clinic); knowing the cost of both anticoagulants, the laboratory cost and the human cost we calculated and compared the yearly expenditure...

: To investigate perioperative and postoperative bleeding, complications in patients under therapy with anticoagulant or antiplatelet drugs submitted to oral surgery. To evaluate the risk of bleeding and safety for dental surgery, a retrospective chart review was performed. Medical and dental records of patients taking oral antithrombotic drugs undergoing dental surgery between 2010 and 2015 were reviewed. Results were statistically analyzed using Fisher's exact test, t test or the χ test. One hundred and seventy-nine patients underwent 293 surgical procedures...

: Quantitative and/or qualitative defects of the platelet membrane glycoprotein IIb/IIIa complex lead to the clinical entity of Glanzmann's thrombasthenia. A large variety of mutations and polymorphisms are responsible for the aberrant expression and defective activity of this heterodimeric complex. The current study aimed to determine the pattern of mutations among Iranian population with Glanzmann's thrombasthenia. A total of 20 patients with Glanzmann's thrombasthenia have been evaluated. All exons and splice sites of ITGA2B and ITGB3 genes were amplified using touchdown PCR...

The optimal duration of anticoagulant therapy after a first episode of unprovoked pulmonary thromboembolism is not fully defined. The identification of patients more prone to recurrence would be useful in this context but is currently relatively unreliable. Perfusion lung scan (PLS) is an established approach for the follow-up of patients with pulmonary embolism to identify recurrences and to help in the diagnosis of chronic thromboembolic pulmonary hypertension. The aim of the study was to investigate the potential role of residual perfusion defects at follow-up perfusion scans in predicting pulmonary embolism recurrences...

: Vascular malformation is occasionally complicated by consumptive coagulopathy, known as localized intravascular coagulopathy (LIC), which is characterized by a reduced fibrinogen level, an elevated D-dimer level and a normal platelet count. We report the case of a 17-year-old Japanese girl who presented with LIC secondary to extensive vascular malformations, whose condition had progressed to disseminated intravascular coagulation (DIC). She suddenly presented with severe anaemia, despite the absence of obvious bleeding, and she began to require regular red blood cell (RBC) transfusions...

: Postoperative venous thromboembolism has a poor prognosis in patients with cancer. We aimed to investigate the utility of thromboelastometry in detecting the risk of postoperative venous thromboembolism in patients with cholangiocarcinoma. We prospectively included patients submitted to liver resection for cholangiocarcinoma at our hospital between May 2011 and July 2014. Patients undergoing major hepatectomy for adult living donor transplantation in the same time period served as a control group. Thromboelastometry was performed before anesthesia...

: Left ventricular (LV) thrombi are mostly formed in the aneurysmal or akinetic segment of the LV apex. Thromboembolism to the brain is usually fatal. There is not enough information available regarding the use of these new oral anticoagulant agents in LV thrombi. In this case, we present a 56-year-old male patient who was given dabigatran (150 mg, twice a day) for paroxysmal atrial fibrillation after experiencing anterior myocardial infarction. During the use of dabigatran, thrombus formation, which was not present earlier, was observed in the LV apical aneurysm...

: Coagulation abnormalities are associated with Puumala-virus-induced hemorrhagic fever with renal syndrome (PUUV-HFRS). We evaluated the coagulation capacity of plasma during acute PUUV-HFRS by measuring thrombin generation using calibrated automated thrombography (CAT). The study cohort comprised 27 prospectively collected, consecutive, hospital-treated patients with acute PUUV infection. Blood samples were drawn in the acute phase and at the control visit approximately 5 weeks later. To evaluate thrombin generation, the lag time of initiation, endogenous thrombin potential (ETP), and peak and time to peak thrombin concentration were assessed by CAT in platelet poor plasma without corn trypsin inhibitor...

: We present a case of a 26-year-old patient with severe infective endocarditis complicated with cerebral septic emboli that required essentially complete replacement of his circulating antithrombin activity to achieve an activated coagulation time near 480 s. The need for this degree of antithrombin administration may have been secondary to ongoing systemic inflammation and consequent thrombin generation despite blood culture results demonstrating no bacteremia. In sum, ongoing loss of endogenous antithrombin activity secondary to inflammation and the need for more than 80% normal activity to conduct safe cardiopulmonary bypass may require extraordinary administration of exogenous antithrombin in similar settings...

: Desmopressin-unresponsive von Willebrand disease patients are treated with substitutive therapy, with both pure von Willebrand factor (vWF) and factor VIII/vWF concentrates. We developed a new purification process, easily scalable to industrial level, to obtain a double virus inactivated highly pure vWF. VWF was purified starting from a waste fraction of already in use human plasma-derived factor VIII manufacturing procedure, using only one anionic-exchange chromatographic step. After chromatography, the product was dialyzed, lyophilized, and heat treated...

: Alterations in coagulation, inflammation and immunity are associated with major injury. As platelets have both coagulation and immune functions, the aim of this study is to correlate platelet activation with the immunoinflammatory response in trauma and burn patients. Blood samples were drawn from trauma and burn patients and healthy volunteers. Platelet (sCD40L) and coagulation (D-dimers) activation, cytokines and inflammatory markers were assessed. sCD40L, D-dimers and cytokines were elevated in both injury groups...

: Previous studies have associated biomarkers indicative of acute inflammation with pulmonary embolism, which may amplify coagulation, inhibit fibrinolysis and increase risk of venous thromboembolism (VTE) recurrence. The aim of this study was to measure inflammatory and hemostatic biomarkers in acute submassive pulmonary embolism at diagnosis and 3-month follow-up and to test the impact of treatment with fibrinolysis. Secondary analysis of a multicenter, double-blinded, randomized controlled trial including patients with submassive pulmonary embolism...

: Life-threatening bleeds are medical emergencies that require time-sensitive decision making. Patients of the Jehovah's Witness faith can present a challenging conundrum when their beliefs conflict with modern treatment options for haemorrhage. Providers may not be aware of the grades of acceptance of the newer products outside of packed red blood cells. Researchers present a case of using four-factor prothrombin complex concentrate in a Jehovah's Witness patient in a life-threatening gastrointestinal haemorrhage along with a brief review of the literature...

: Intracranial hemorrhage (ICH), as a life-threatening bleeding among all kinds of congenital bleeding disorders (CBDs), is a rare manifestation except in factor XIII (FXIII) deficiency, which is accompanied by ICH, early in life, in about one-third of patients. Most inherited platelet function disorders (IPFDs) are mild to moderate bleeding disorders that can never experience a severe bleeding as in ICH; however, Glanzmann's thrombasthenia, a common and severe inherited platelet function disorder, can lead to ICH and occasional death...

: Intraventricular hemorrhage (IVH) is a significant cause of morbidity in extremely premature infants despite many advances in neonatal intensive care. We conducted an institutional retrospective review aimed to correlate risk factors associated with IVH. Clinical variables reported to the Vermont-Oxford Network on less than 30 weeks gestational age infants over a 5-year period were evaluated with Pearson's chi-square and multivariate logistic regression. Of 618 infants born less than 30-week gestational age, 178 (28...
