BackgroundPregnancy in patients with advanced chronic kidney disease (CKD) is associated with a high risk of adverse outcomes for the mother and the fetus, but data on the characteristics of the course of pregnancy in these women is limited.AimTo analyse of the course and outcomes of pregnancy in patients with CKD stages 3a4.Materials And MethodsThirty five pregnant women with CKD stages 34 were included: 3a 12 (34.3%) patients, stage 3b 10 (28.6%), stage 4 13 (37.1%).ResultsProteinuria, serum creatinine, blood pressure in dynamics, the presence of a physiological response were investigated. Pregnancy management included blood pressure correction, antianemic, antiplatelet, anticoagulant therapy, prevention and treatment of urinary infection, correction of metabolic disorders. All pregnant women had proteinuria of varying severity, which increased towards the end of pregnancy. Seventeen (51.5%) patients had hypertension, successfully corrected with antihypertensive drugs. The average delivery term was 34.6 weeks. Preeclampsia developed in 14 (42.4%) cases, an inverse relationship was found between the presence of a physiological response and preeclampsia (p=0.009; rs=-0.463). All children were born alive and viable. After delivery in patients with CKD 3a creatinine values returned to the pre-gestational level, in patients with grade 3b and 4 progression of CKD was noted.ConclusionA favorable pregnancy outcome in women with late stages of CKD is possible with constant monitoring by a multidisciplinary team of doctors with mandatory monitoring of renal function, proteinuria, blood pressure, coagulation, markers of preeclampsia and indicators of fetal health. It was proposed to consider the physiological response of the kidneys to pregnancy as a predictor of a favorable outcome.
