    Folate cycle drugs in the complex preventive therapy for the miscarriage
    (Полтавський державний медичний університет, 2021) Mishchenko, V. P.; Rudenko, I. V.; Likhachov, V. K.; Gromova, A. M.; Tarasenko, K. V.; Міщенко, Валентина Павлівна; Руденко, Ірина Василівна ; Ліхачов, Володимир Костянтинович; Громова, Антоніна Макарівна; Тарасенко, Костянтин Володимирович
    120 women of reproductive age were examined. Alleles of folate-related enzyme genes, the content of folic acid, cyanocobalamin, vitamins B1, B6 in the blood were determined. Prevention of miscarriage was based on preconception training of men and women (spouses). The pre-conceptual examination plan included a thorough study of the anamnesis, including family history; laboratory determination of folic acid, vitamins B12, B1, B6 in the blood of future parents (both woman and man). Decreased vitamin content or their level at the lower limit of normal was an indication for determining the folate-related enzyme genes (MTHFR: 1298A/C; 677C/T, MTR: 2756A/G, MTRR: 66A/G). Given the high (78.1 %) incidence of carriers of “functionally attenuated” (polymorphic) genes of folate cycle enzymes, both expectant parents were prescribed modern complexes of vitamins, microelements and amino acids containing Metafolin at the stage of preconception preparation 3-4 months before fertilization and during pregnancy according to the trimesters of gestation. Clinical and laboratory approach to the correction of vitamins, macro-, microelements, amino acids based on laboratory assessment of hereditary impairment of specific enzymes and by prescribing personalized therapy had a positive result in 57 (95.0 %) patients, which confirms its effectiveness.
