Continuous glucose monitoring-enabled insulin-pump therapy in diabetic pregnancy

Abstract

We describe the feasibility of continuous glucose monitoring (CGM)-enabled insulin-pump therapy during pregnancy in a woman with type 1 diabetes, who was treated with CGM-enabled insulin-pump therapy in her third pregnancy. During her first pregnancy, the woman was treated with multiple daily injections and baseline HbA1c was 8.9%. Due to pre-eclampsia, the child was born preterm, and had neonatal hypoglycemia. In the planning of the second pregnancy, insulin-pump therapy was initiated, resulting in an HbA1c of 6.8% in early pregnancy. Due to pre-eclampsia, the second child was born preterm, but without neonatal morbidity. Before her third pregnancy, CGM-enabled insulin-pump therapy was introduced, and HbA1c was 6.4% in early pregnancy. The patient was satisfied with this therapy, pre-eclampsia did not occur, and the child was born at term without neonatal morbidity. CGM-enabled insulin-pump therapy appears feasible in diabetic pregnancies.
