Apolipoprotein E and PAI-1 gene polymorphisms and no association with arterial ischemic stroke and peripheral arterial disease manifestations
Jornal Brasileiro De Patologia E Medicina Laboratorial(2018)
摘要
ABSTRACT Introduction: Arterial thrombosis is considered a multifactorial disease, resulting from the interaction of genetic and acquired risk factors. Objectives: The aim of this study was to investigate the presence of the polymorphism in inhibitor of plasminogen activator type 1 (PAI-1) and apolipoprotein E (ApoE) genes and its interactions with PAI-1 levels and lipids and apolipoprotein profiles, respectively, as well as the frequencies of these polymorphisms and their association with thrombosis. Methods: Ninety-seven patients [48 with arterial ischemic stroke (IS) and 49 with peripheral arterial disease (PAD)], treated at the hematology medical service were included in this study. Polymorphisms were also investigated in 201 control subjects. Polymorphisms were investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results: For the PAI-1 polymorphism, there were 54.2% heterozygous (HT) genotypes and 12.5% homozygous (HM) genotypes in the patients' group, and 52.7% HT genotypes and 21.3% HM genotypes in the controls. For the ApoE polymorphism, there were 56.3% (e3e3), 6.3% (e4e4), 8.3% (e2e3), 4.2% (e2e4) and 24.9% (e3e4) in the patients, and 61.2% (e3e3), 4.5% (e4e4), 8% (e2e3), 4.5% (e2e4) and 21.8% (e3e4) in the controls. Conclusion: No significant difference was observed by comparing patients and controls. In this study, no association was found between the presence of the evaluated polymorphisms and the occurrence of thrombotic events.
