Clinical features of the course of overt diabetes mellitus during pregnancy

Abstract

Objective: to analyze the features of diagnosis, course and outcomes of pregnancy in women with manifest diabetes mellitus.Materials and methods: the study included 19 delivery medical records of women with MDM (manifest diabetes mellitus during pregnancy) and 500 records of women with GDM (gestational diabetes mellitus).Results: Th irteen women out of nineteen were diagnosed with MDM in the fi rst half of pregnancy. Th e average level of glycemia at the onset of the disease was 9,3±3,0 mmol/l. Mean HbA1c was 7,2±1,1%, which signifi cantly exceeded this indicator in GDM. All women with MDM required insulin therapy, while in the group of women with GDM insulin therapy was used in 27.8% of cases. MDM women showed increased rates of preeclampsia (36,8%) compared to GDM women (15%). Fetal macrosomia was more common in MDM women (36.8%) than in GDM women (17%).Conclusion: Th e high frequency of obstetric and perinatal complications of MDM during pregnancy requires the early detection of hyperglycemia and the prompt initiation of insulin therapy. Screening for carbohydrate metabolism disorders at the fi rst prenatal visit and early initiation of insulin therapy reduce maternal and perinatal mortality.
