| description | This review article is aimed at highlighting and analyzing the manifestations of endothelial dysfunction
in overweight pregnant women that has been recognized as one of the most challenging issues in current obstetrics.
Obesity has already been stated as one of the most widespread diseases around the world. According to the World
Health Organization, more than 25% of women are diagnosed as overweight, and there is a tendency toward an
increase in the obesity incidence in pregnant women. Obesity in pregnant women can cause maternal and prenatal
complications, and namely, pre-eclampsia, miscarriage, placental dysfunction, fetus intrauterine growth retardation.
In Ukraine, preeclampsia occurs in 12-17% of cases and develops in 8-12% of healthy pregnant women and in
20-40% of pregnant women with intercurrent pathology. Therefore, determining the causes of preeclampsia in
pregnant women with concomitant obesity is an important task. The trigger mechanism for the development of this
complication of pregnancy results from the endothelial damage to the vessels in the pre-pregnancy period and is
typically associated with such factors as arterial hypertension, obesity, dyslipidemia.
The development of placental dysfunction and its clinical manifestations including intrauterine growth
retardation syndrome and chronic fetal distress is an essential aspect in the course of pregnancy that causes high
prenatal morbidity and mortality. The placental process starts with the interaction between the cytotrophoblast and
the decidual tissue of the endometrium. The intensity of utero-placental blood flow is the main factor determining the oxygen supply to the placenta. In the case of uncomplicated pregnancy, placental vessels are dilated and do not
respond to contractile stimuli that ensures smooth regular supply of oxygen and nutrients to the fetus.
Endothelial dysfunction is a universal pathogenetic mechanism of most diseases, as the endothelium not only
regulates the vascular tone, but also takes part in the processes of atherogenesis, thrombosis, and provides the
protection of the vascular wall the integrity. In addition, the endothelium produces a large number of biologically
active substances that affect the tone and vascular angiogenesis, regulate hemostasis, immune and anti-inflammatory
response.
The reduction in the synthesis of nitric oxide (NO), which is the main vasodilator, and also is involved in the
functioning of various systems of the human body, and in particular, cardiovascular, immune, and endocrine, is
considered as a key element of endothelial dysfunction. Nitric oxide is derived from L-arginine under the action of
the NO-synthase enzyme. It is the L-arginine NO system that according to the current views in obstetrics plays a
leading vasoregulatory role during the gestation. The presence of endothelial dysfunction in pregnant women with
preeclampsia can be due to the low level of substances responsible for vasodilation.
Consequently, obesity in women of child-bearing age is associated with a number of systemic and reproductive
problems that leads to a decrease in fertility. Pregnancy and childbirth are complicated by preeclampsia, the threat
of abortion, miscarriage and intrauterine damage of the fetus. All this indicates a further need to improve measures
aimed at prenatal fetal protection and reducing the frequency of maternal and fetal complications in this group
of pregnant women, and states the necessity for early detection of women with an increased risk of placental
syndromes (preeclampsia, fetal delay, etc.). |
