Uppugunduri CR, Daali Y, Desmeules J, Dayer P, Krajinovic M, Ansari M. Transcriptional regulation of CYP2C19 and its role in altered enzyme activity. Curr Drug Metab. We assessed the impact of only 1 single genetic and functionally relevant variant on ADP-induced platelet aggregation and patient clinical outcome. Patients were interviewed by telephone after 30 days (±7 days). The median ADP-induced platelet aggregation values across The primary safety end point (combined TIMI major and minor bleedings) within 30 days occurred in 51 patients (3.3%) of the study population. By continuing to browse this site you are agreeing to our use of cookies.In coronary artery disease patients undergoing percutaneous coronary intervention (PCI), aggressive antithrombotic and anticoagulant treatment regimens are routinely administered to reduce the risk of thrombotic complications. The other authors report no conflicts.Responsiveness to clopidogrel treatment, as assessed in vitro by the measurement of ADP-induced platelet aggregation, is characterized by large interindividual variability. Forty-nine bleedings (96%) were in-hospital bleeding events. The sponsors had no role in the design and conduct of the study; collection, management, analysis, and interpretation of the data; or preparation, review, or approval of the manuscript.Dr Sibbing has received speaking fees from Dynabyte and fees for advisory board activities from Eli Lilly. By contrast, the gain-of-function allele CYP2C19*17 has been linked with a better response to clopidogrel and, accordingly, a higher risk of bleeding . Epub 2012 Nov 20. Review. Background— The cytochrome P450 (CYP) 2C19 isoenzyme plays an important role in clopidogrel metabolization. According to The primary efficacy end point (combined definite or probable ST) within 30 days occurred in 14 patients (3.3%) of the study population. This risk reduction, however, comes with an increased risk of bleeding complications during and after the procedure.Dual antiplatelet treatment with aspirin and clopidogrel is routinely administered to prevent thrombotic events after coronary stent placement; however, this therapy significantly contributes to the occurrence of bleeding events.Clopidogrel, an inactive prodrug, requires metabolization and activation by the hepatic cytochrome P450 (CYP) system to generate its active thiol metabolite, which targets and irreversibly inhibits the ADP P2Y12 receptor.In contrast to the numerous studies linking high postclopidogrel treatment platelet reactivity to an increased risk of ischemic events, including ST,Between February 2007 and April 2008, patients with coronary artery disease and planned drug-eluting stent placement were enrolled in this study. Details of this method have been reported previously.Patients stayed in the hospital for at least 2 days after study inclusion and after PCI.

Geometric mean of the escitalopram serum concentration was 42% lower in patients homozygous for CYP2C19*17 (P<0.01) and 5.7-fold higher in subjects homozygous for defective CYP2C19 alleles (P<0.001).

Genomic DNA was extracted from 200 μL blood with commercially available kits (NucleoSpin Blood Quick Pure, Macherey-Nagel, Duren, Germany) according to the manufacturer’s instructions. A further limitation of the present study is that this analysis was a post hoc analysis of a study population that stems from a prospective trial; therefore, it is subject to the limitations inherent to all such analyses.This study was funded from Deutsches Herzzentrum, Munich, Germany (grant KKF 1.1-05, 984323). Ten definite STs and 4 probable STs according to Academic Research Consortium criteria were observed.
