Purpose of the study: Rational for the use of folates for the prevention of fetal growth restriction on the basis of the identification of a MTHFR polymorphism.Material and methods: 200 patients (case-control) were enrolled in the study. The (main) group I included 100 patients with fetal growth restriction (FGR), the (control) group II included 100 conditionally healthy patients. The features of the anamnesis, the initial clinical characteristics, the course of pregnancy, childbirth and the postpartum period in patients with placental insufficiency were studied in detail, and the features of the early neonatal period were analysed comprehensively. At the second stage, the polymorphism of the MMP2, MMP3, MMP9, and MTHFR genes was studied and their dependence with the development of the FGR was established. Statistical processing of the results was carried out on a personal computer using the SPSS Statistics 17.0 for Windows software package.Results:The clinical risk factors for the development of FGR include: chronic pyelonephritis, medium degree myopia, varicose veins, threat of abortion, ultrasound-detected subchorionic hemorrhage in the I trimester of gestation, anemia. Along with clinical risk factors for ZRP, the carriage of MTGFR (677 C> T) polymorphism is also considered, which justifies its identification in patients at risk.Conclusion: The data obtained make it possible to use the identification of MTHFR polymorphism as a predictor of placental abnormalities during pregnancy and to start taking folic acid supplements at the preconception stage in good time. Femibion 1 vitaminmineral complex has proved to be an effective product that is suitable for women in the period of preparation for pregnancy and in the first trimester of gestation, reducing the risk of fetal malformations and endothelial dysfunction caused by a violation of folic acid metabolism.
