PREVENTION OF PLACENTAL INSUFFICIENCY IN PREGNANT WOMEN WITH DIFFUSE GOITER AND HYPOTHYROXINEMIA

Abstract

Objective: To assess the clinical acceptability of prevention of placental insufficiency (PI) by nitric oxide donators (NOD) in pregnant women with diffuse goiter. Methods: Data from 70 pregnant women with diffuse goiter and hypothyroxinemia were analyzed; including 45 (64.3%) patients (I group) received iodine-containing drugs (ICD) and 25 (35.7%) patients (II group) received ICD and NOD Tivortin in combination with Tocopherol in the second trimester of pregnancy. Control of the effectiveness of therapy conducted according to data of dopplerometry in the third trimester of pregnancy. Results: Of the 45 patients in the group I, 15 (33.3%) were in the cases of dopplerometrically diagnosed disorders of uterine-fetus-placental blood flow: in 8 (53%) cases compensated, in 7 (47%) cases subcompensated. In all women with a subcompensated form of PI, the pregnancy has been complicated by pre-eclampsia. Of the 25 patients in the second group, only 2 (8%) were in the observations revealed the compensated form of the PI. Conclusion: In diffuse goiter and gestational hypothyroxinemia, the prevention of iodine deficiency, which involves taking iodine-containing drugs reduces the frequency of PI. However, the implementation of comprehensive prevention of PI, which provides the filling of the deficiency of nitric oxide, gives the best results. Apparently, in the studied iodine-deficiency status, despite the replenishment of iodine deficiency, develops pathological dysfunction of the endothelium. The use of NOD at the beginning of the second trimester of pregnancy, during the period of active angiogenesis, contributes to the normal formation and functioning of chorion vessels, as well as explains the difference in the frequency and severity of hemodynamic disorders depending on the prevention of PI.
