Metabolic Syndrome in Reproductive Age Women of Various Ethnic Groups. Neuroendocrine Status and Lipid Peroxidation...

We analyzed the state of neuroendocrine regulation and LPO-antioxidant defense systems in reproductive age women with metabolic syndrome (MetS), representatives of the Russian and Buryat ethnic groups. Compared to the corresponding control groups, women from the Russian ethnic group with MetS had elevated levels of thyroid-stimulating hormone and free androgen index (FAI) and reduced levels of sex hormone-binding globulin, while women from the Buryat ethnic group had increased levels of prolactin and FAI. Changes in the LPO system in women of the Russian ethnic group with MetS consisted in an increase in the levels of substrates with double bonds, TBA-reactive substances, and fat-soluble vitamins. Buryat women with MetS had a higher content of primary oxidation products and reduced levels of glutathione. The results of the study indicate a hyperandrogenic shift in the neuroendocrine regulation system, as well as compensatory influences from different parts of the antioxidant defense system in women of reproductive age with MetS, depending on their ethnicity. These findings indicate the need for assessing and monitoring the levels of these metabolites in women with MetS, considering their ethnicity.
