Abstract
This case report described a 78-year-old woman with type 1 diabetes who experienced a significant decrease in the hemoglobin glycation index (HGI) after switching her insulin pump from MiniMed™770G to 780G. Despite minimal changes in glycemic control, including a slight decrease in the average sensor glucose and % coefficient of variation (%CV) from continuous glucose monitoring metrics, her glycated hemoglobin level decreased from 8.2% to 7.3%, and HGI decreased from approximately 1.3–0.5. Previous reports have shown that HGI indicates differences in the glycation rate of hemoglobin between individuals. Moreover, a high HGI is a risk factor for diabetic complications. However, there are no reports on changes in HGI within an individual. Therefore, the significance of intraindividual HGI changes, as in this case, should be investigated.
期刊介绍：
Journal of Diabetes Investigation is your core diabetes journal from Asia; the official journal of the Asian Association for the Study of Diabetes (AASD). The journal publishes original research, country reports, commentaries, reviews, mini-reviews, case reports, letters, as well as editorials and news. Embracing clinical and experimental research in diabetes and related areas, the Journal of Diabetes Investigation includes aspects of prevention, treatment, as well as molecular aspects and pathophysiology. Translational research focused on the exchange of ideas between clinicians and researchers is also welcome. Journal of Diabetes Investigation is indexed by Science Citation Index Expanded (SCIE).
