Background: The problem of glucose variability has been in focus for type 1 diabetes mellitus (T1DM) on insulin treatment. Daily profile of blood glucose was studied on Continuous Glucose Monitoring (CGM) using Free Style Libre.
Case presentation and results: Patient is 54 year-old T1DM female, with HbA1c 7.8%. The blood glucose variability was measured by Free Style Libre. Insulin therapy included multiple daily insulin injection (MDI) of Insulin Glargin and Aspart. The result revealed unstable blood glucose profile in day 1 and 2. After that, the level and fluctuation of blood glucose gradually decreased from day 3 to 14. Average blood glucose in a day was 174mg/dL, 159mg/dL, 138mg/dL, 125mg/dL and 110mg/dL, in day 2, 4, 7, 9, 11, respectively. There was a discrepancy of HbA1c between 7.8% by laboratory measurement and 6.3% presumed value by Free Style Libre.
Discussion and Conclusion: Free Style Libre showed satisfactory results as CGM. There was lower HbA1c value by presumed calculation, which would be possibly due to every 15minutes measurement and difficulty in checking abrupt glucose surges. CGM application would probably bring diabetic subjects behavioral change of life style, leading to better diabetic control. These results would become reference data in CGM study for future research.
