Continuous subcutaneous insulin infusion reduces neonatal risk in pregnant women with type 1 diabetes mellitus

Abstract
Objectives: An attempt was made to demonstrate the superiority of the treatment model using continuous subcutaneous insulin infusion (CSII) over multiple daily injections (MDI) of insulin in achieving a successful pregnancy outcome and good newborn’s condition in patients with type 1 diabetes.
Material and methods: The study included 297 infants born to type 1 diabetic patients; 175 patients were treated with MDI and 122 with CSII.
Maternal metabolic control during pregnancy, gestational weight gain, insulin requirements, pregnancy outcome and neonatal status were compared between MDI and CSII arm.
The composite adverse neonatal outcome was diagnosed if at least one of the following was found: abnormal birth weight (LGA or SGA), congenital malformation, miscarriage, intrauterine fetal death, emergency CS due to fetal risk, iatrogenic prematurity, RDS, hypoglycemia, hyperbilirubinemia, and the postpartum pH in the umbilical artery ≤ 7.1.
Results: The studied groups did not differ regarding gestational week at delivery, a proportion of births at full term, preterm births, miscarriages, or late pregnancy losses (intrauterine fetal death > 22 weeks). Newborns of mothers treated with CSII showed lower incidence of neonatal complications (composite adverse neonatal outcome) compared to those of mothers treated with MDI (60% vs 74%, respectively; p = 0.01). We did not find any association between the mode of treatment and composite adverse maternal outcome.
Conclusions: The use of CSII in the treatment of pregnant women with type 1 diabetes was associated with reduced number of neonatal complications presented as neonatal composite outcome but had no influence on maternal outcome.
