Molecular genetic markers of predisposition to thrombosis in adolescents with essential hypertension

Abstract

AIM. To estimate the spread and distribution of genotypes and alleles of thrombosis predisposition gene polymorphisms in adolescents with essential hypertension (EH). MATERIALS AND METHODS. One hundred and thirty-seven 14- to 17-year-old adolescents were examined. There were 3 examined groups: 1) 37 EH patients with prothrombotic changes (PTC); 2) 60 EH patients without PTC; 3) 40 healthy adolescents. Prothrombin time, activated partial thromboplastin time, and the levels of fibrinogen and soluble fibrin monomer complexes were determined. The adolescents were assigned to a PTC group if they had changes by one or several above indicators. Polymerase chain reaction assay was used to type coagulation factor II (FII) and factor V (FV), plasminogen activator inhibitor type 1 (PAI-1), 5,10-methylenetetrahydrofolate reductase (MTHFR), and methionine syntase reductase (MTRR) gene polymorphisms. Group differences were determined by qualitative signs, by using the χ2 test and Yates' correction for continuity and Fisher's exact test if one of the groups had at least 5 individuals. All differences were considered statistically significant at p
