Satisfactory Rapid Response to Xultophy Associated with Meal Tolerance Test (MTT) by Carbohydrate Loading

Abstract

The case is a 69-year-old male patient with Type 2 Diabetes Mellitus (T2DM) for 21 years. His diabetic control was not so satisfactory, and his HbA1c value increased in spring 2021. Then, he started Xultophy (IDegLira), which includes a fixed ratio of two agents of basal degludec and liraglutide. Just after providing Xultophy, the daily profile of blood glucose decreased from 179-400 mg/dL to 112-171 mg/dL, with remarkable clinical efficacy. He usually takes 80g of carbohydrates in breakfast, and the meal tolerance test (MTT) was challenged. As carbohydrate loading was given 100-75-50-0%, postprandial hyperglycemia at 60-min showed 277-219-159-133 mg/dL, respectively.
