[THE CHARACTERISTICS OF COURSE OF PREGNANCY RESULTED FROM EXTRA-CORPOREAL IMPREGNATION AGAINST THE BACKGROUND OF...

The pregnancy that occurred due to in vitro fertilization is characterized by higher risk of development of gestational diabetes mellitus. The purpose of the study was to investigate course and outcomes of pregnancy resulted from in vitro fertilization in women with gestational diabetes mellitus, depending on time of its manifestation. The analysis of course of pregnancy, childbirth and condition of newborns in 179 women with gestational diabetes mellitus under pregnancy resulted from in vitro fertilization was carried out. It is established that early manifestation of gestational diabetes mellitus is associated with older age of pregnant women, higher rate of birth of large fetus in anamnesis, higher body mass index, more frequent prescription of insulin therapy to treat gestational diabetes mellitus, higher rate of development of early threatened miscarriage, isthmic cervical insufficiency, anemia, chronic arterial hypertension, gestational arterial hypertension, moderate preeclampsia, severe preeclampsia, premature normally placed placenta detachment, fetal growth retardation, chronic intrauterine fetal hypoxia, diabetic fetopathy, prenatal rupture of amniotic fluid, premature birth, more frequent birth of large fetus, development of fetal renal pyelectasia. The female patients with late manifestation of gestational diabetes mellitus had higher level of fasting plasma glycemia, frequent development of placenta previa, polyhydramnios, pathological and insufficient gain of body mass during pregnancy, dis-coordination of labor and clinically narrow pelvis during labor, more frequent operative delivery and early delivery. The gestational diabetes mellitus, developed both in early and late periods, complicates the course and childbirth under pregnancy resulted from in vitro fertilization, adversely affects state of the newborn. The study in depth is needed to establish possible mechanisms of development of gestational diabetes mellitus in this cohort of women with implementation of screening examinations and determination of further tactics of management of pregnancy depending on time of its manifestation.
