The aim of the present study is to assess the impact of adding oral metformin to insulin therapy in pregnant women with insulin-resistant diabetes mellitus. The current non-inferiority randomized controlled trial was conducted at Ain Shams University Maternity Hospital. The study included pregnant women with gestational or pre-existing diabetes mellitus at gestations between 20 and 34 weeks, who showed insulin resistance (defined as poor glycemic control at a daily dose of ≥1.12 units/kg). Recruited women were randomized into one of two groups: group I, including women who received oral metformin without increasing the insulin dose; and group II, including women who had their insulin dose increased. The primary outcome was maternal glycemic control. Secondary outcomes included maternal bouts of hypoglycemia, need for another hospital admission for uncontrolled diabetes during pregnancy, gestational age at delivery, mode of delivery, birth weight, birth trauma, congenital anomalies, 1- and 5-min Apgar score, neonatal hypoglycemia, need for neonatal intensive care unit (NICU) admission and adverse neonatal outcomes. A total number of 154 women with diabetes mellitus with pregnancy were approached; of them 90 women were eligible a...Continue Reading
