Article of Interest (Epigenetics): Histone H4, Thrombosis & Inflammation
Molecular Circuits in Thrombosis and Inflammation. Esmon CT, 2013, Throm Haemost 109 (3):416-420 "In addition to the direct prothrombotic activity of histone-DNA complexes, the complexes trigger activation of the toll-like receptors 2, 4 and 9 thereby increasing inflammatory cytokine formation and fostering thrombotic responses through the mechanisms mentioned previously."
Article of Interest (Coagulation): Effect of Oral Contraceptive on protein S and TFPI
The effect of different hormonal contraceptives on plasma levels of free protein S and free TFPI. Raps M et al, 2013, Throm Haemost 109(4):[ahead of print] "The effect of oral contraceptives on TFPI and PS is a possible explanation for the increased risk of venous thrombosis associated with oral contraceptives"
Article of Interest:Vascular Biology
Early Vascular Alterations in SLE and RA Patients—A Step towards Understanding the Associated Cardiovascular Risk. Jose M et al, PLOS ONE www.plosone.org 1 September 2012 Volume 7 Issue 9
Article of Interest (Coagulation):Factor Concentrates
The early use of fibrinogen, prothrombin complex concentrate, and recombinant-activated factor VIIa in massive bleeding.
Is There a Difference in Anticoagulation Stability Between Domiciliary-Based and Hospital-Based Patients?
A study of patients in three different monitoring settings showed domiciliary-based patients had the poorest anticoagulation control.
Article of Interest (Coagulation) -The population pharmacokinetics of R- and S-warfarin: effect of genetic and clinical factors.
What is already known about this subject: A number of pharmacokinetics studies have focused on S-warfarin. These have shown that demographic factors, such as bodyweight, genetic factors, such as CYP2C9 genotype, and interacting medicines, particularly amiodarone, contribute to the interindividual estimates of clearance. What this study adds: This study not only reinforces what has previously been learned about S-warfarin, but also provides an insight into the pharmacokinetics of R-warfarin.
Article of Interest (Coagulation) – Pharmacokinetics and pharmacodynamics following maintenance doses of prasugrel and clopidogrel in Chinese carriers of CYP2C19 variants.
What is already known about this subject: Observation from clinical studies have demonstrated that: • CYP2C19 genotype does not have a clinically relevant effect on active metabolite concentrations or platelet inhibition in prasugrel-treated subjects • Variability of response to clopidogrel active metabolite and reduced platelet inhibition lead to increased adverse cardiovascular events in patients with acute coronary syndromes
