A 'picturesque' case of transition from subcutaneous to oral treatment in neonatal diabetes.

We report a case of a 6-week-old infant with diabetes mellitus based on a genetic defect in the sulfonylurea receptor 1 (SUR1), an ATP-sensitive potassium (KATP) channel protein. A spectacular improvement in glucose regulation was shown by real-time continuous glucose monitoring when switching her from insulin to oral glibenclamide. Children with neonatal onset of diabetes deserve genetic testing in order to replace insulin with oral medication.
