[Cord blood erythropoietin in relation to glycemic control in the last weeks of pregnancy].

The relationship between cord blood erythropoietin (EPO) and maternal HbA1c and fructosamine levels were examined in the aim to answer a question, whether occurrence of prenatal hypoxia in newborns of diabetic mothers depends from maternal glycemic control during the last weeks of pregnancy. The study was performed in the group of 178 mothers and newborns divided into two groups: diabetic and control. The diabetic group consisted of 116 mothers (33 with IDDM and 83 with GDM) and newborns and the control group consisted of 62 healthy mothers and newborns. Maternal HbA1c (Micro Column Test BIORAD Prospecta) and fructosamine (Roche fructosamine Test) levels were estimated on the day of delivery. Cord blood to estimate EPO (radioimmunoassay) and fructosamine levels were drawing immediately after delivery the babies. The relationship between the study parameters were calculated on the basis of a covariance analysis test. In the diabetic group the significant positive correlation between EPO and maternal HbA1c and fructosamine levels was found as well as between EPO and fetal fructosamine levels. We conclude that higher levels of cord blood EPO are associated with poor maternal glycemic control during the last weeks of pregnancy.
