Perinatal and neonatal outcomes of pregestational diabetes mellitus: a retrospective study

Background: The aim of the study was to evaluate maternal-foetal and neonatal clinical outcomes in a group of patients with pregestational diabetes mellitus (PGDM) such as diabetes mellitus type 1 (DM1), diabetes mellitus type 2 (DM2), and maturity onset diabetes of the young (MODY).MethodsOverall, 174 pregnant women, nulliparous and multiparous, with single pregnancy were enrolled. The selected patients were divided into two groups: PGDM (42 with DM1, 14 with DM2, and 2 with MODY); 116 patients with a negative pathological history of diabetes mellitus were the control.ResultsWe reported an incidence of preterm delivery of 55.2% in the PGDM group, of 59.5% in the DM1 group, and 42.9% in the DM2 group VS. 6% in the controls. Foetal growth disorders, such as intrauterine growth retardation, small for gestational age, and foetal macrosomia were found in 19% and 3.6% in the case and in the control group, respectively. A relationship between DM2 and gestational hypertension was found.Conclusionspatients with PGDM are at increased risk of perinatal and neonatal complications in comparison with pregnant women without PGDM.
