INTRODUCTION AND OBJECTIVES CYP2C19*2 and CYP2C19*17 alleles appear to contribute to heterogeneous clopidogrel metabolism. The aims of the present study were to assess the phenotype-genotype relationship of CYP2C19*2 and *17 allele carriage and to explore the clinical impact of those polymorphisms at 6-month follow-up of an acute event in an unselected(More)
BACKGROUND The involvement of iron in anthracycline cardiotoxicity is supported by extensive experimental data, and by the preventive efficacy of dexrazoxane, an iron chelator. However, no clinical evidence of anthracycline-induced cardiac iron accumulation is available and the influence of previous iron overload or of genetic factors in human-induced heart(More)
OBJECTIVE Treatment with anthracyclines may cause cardiac dysfunction, but the sequence of anthracycline-induced heart lesions has been incompletely characterized. NADPH oxidase, a key mediator of oxidative cardiac damage and remodeling, modulates anthracycline clinical cardiotoxicity. Our aim was to determine which cardiac histological lesions are(More)
Genetic factors involved in the interindividual variability of antithrombin have not been identified. We studied two polymorphisms of the gene coding for antithrombin (SER-PINC1) in 298 Spanish Caucasian blood donors: rs3138521, a DNA length polymorphism located on the promoter region and rs2227589, a SNP located on intron 1 that has been described as a(More)
Somatic mutations in the CALR gene were recently discovered in a substantial proportion of Philadelphia-negative chronic myeloproliferative neoplasm (cMPN) patients lacking JAK2 and MPL mutations. Somatically acquired defects are not the only pathogenic mechanism involved in these disorders. Since germline JAK2 46/1 haplotype predisposes to cMPN-associated(More)
Hereditary disorders of primary hemostasis, characterized by mucocutaneous bleeding (MCB), are highly prevalent in children. Few cases are clearly monogenic, but the overwhelming majority are classified as mild bleeding disorders, with wide clinical and laboratory heterogeneity suggestive of complex polygenic diseases. In this framework, and by homology(More)
2596 Background: Anthracyclines (ANT)-induced cardiotoxicity is a growing problem in cancer survivors. Polymorphisms of NAD(P)H oxidase, involved in cardiac oxidative stress and remodeling, have been associated to cardiac dysfunction in ANT-treated individuals. Although no clear correlation has been found between pathologic findings and clinical events(More)
