Multicenter StudyThrombomodulin alfa treatment in patients with acute promyelocytic leukemia and disseminated intravascular coagulation: a retrospective analysis of an open-label, multicenter, post-marketing surveillance study cohort.
Patients with acute promyelocytic leukemia (APL) can develop disseminated intravascular coagulation (DIC) that results in life-threatening hemorrhagic complications. Studies regarding the safety and efficacy of thrombomodulin alfa (TM-α; recombinant human soluble thrombomodulin) in patients with APL and DIC are limited. ⋯ This study confirmed the safety and efficacy of TM-α in daily clinical practice for patients with APL and DIC. TM-α appeared to reduce hemorrhagic early deaths due to DIC in patients with APL who were receiving antileukemic treatment.

The effects of recombinant activated factor VII dose on the incidence of thromboembolic events in patients with coagulopathic bleeding.
Previous studies have suggested the used of off-label recombinant factor VII (rFVIIa) increases the risk of thromboembolic events, but the effect of the dose of rFVIIa is not well described in the literature. ⋯ No significant difference in the incidence of thromboembolic events was seen between low dose versus high dose rFVIIa over a seven year period at our institution. However, due to the relatively low overall incidence and a small sample size, type II error may be present.

N-methyl-D-aspartate receptors amplify activation and aggregation of human platelets.
Glutamate is stored in platelet dense granules and large amounts (>400 μM) are released during thrombus formation. N-methyl-d-aspartate glutamate receptors (NMDARs) have been shown in platelets but their roles are unclear. ⋯ Our results support an active role for NMDARs in platelets, in a process that involves activation-dependent receptor relocation towards the platelet surface.

Should women suffering from migraine with aura be screened for biological thrombophilia?: results from a cross-sectional French study.
Migraine, particularly migraine with aura (MA), is associated with a higher risk for ischemic stroke (IS). A procoagulant state may predispose to IS. Whether inherited biological thrombophilia are associated with migraine risk remains controversial. ⋯ FVL or FIIL mutations were more likely among patients suffering from MA. Whether biological thrombophilia screening should be systematically performed in women suffering from MA remains to be determined.
