Some indicators of biochemical and hormonal homeostasis in internally displaced women with threatened miscarriage, living in the Luhansk region
Background. The threatened miscarriage is the most common pregnancy complication that occurs in 15-20 % of cases of ongoing pregnancy. The aim of this work was to study the features of electrolyte status and level of vitamin 25(OH)D in pregnant women with threatened miscarriage in I and II trimesters, living in the Luhansk region and having the status of internally displaced persons (IDP), to improve treatment and preventive measures and prevent obstetric and perinatal complications in such women. Materials and methods. The study included 27 pregnant women who had IDP status and were hospitalized for threatened miscarriage to the hospitals, located in the Luhansk region (group I). The control group consisted of 30 pregnant women with no relevant past medical history and with physiological course of pregnancy with similar gestation period (group II). Clinical and obstetric examinations were carried out, the content of vitamin 25(OH)D and the concentration of trace elements such as Na+, K+, Cl+, Ca2+, P, Mg, Zn in the blood serum were determined. Results. It was found that in pregnant women of group I, the concentrations of magnesium (0.74 (0.73-0.78)) and vitamin 25(OH)D (26.85 (23.38-29.04)) were significantly lower compared with the control group (0.79 (0.75-0.83) and 28.21 (25.85-29.15), respectively). In group I, a statistically significant positive correlation was found between the concentrations of vitamin 25(OH)D and ionized calcium (r = 0.445, p = 0.02), between the content of phosphorus and the body mass index (r = 0.456, p = 0.017). Conclusions. Antenatal study of electrolyte and vitamin 25(OH)D content in the blood serum of pregnant women with symptoms of threatened miscarriage and IDP status will allow us to individualize the approach to the management of pregnancy and to develop timely, if necessary, corrective and rehabilitation measures that will contribute to a successful pregnancy outcome and influence the health of the mother and her offspring.
