386-P: Acute Hypoglycemia Does Not Alter Serum Levels of Amyloid-Related Proteins Associated with Dementia

Objective: Hypoglycemia is a common complication of tighter glucose control regimens in type 2 diabetes (T2D) and may increase the risk of dementia, Alzheimer’s disease being the most common form. We measured amyloid-related proteins during induced hypoglycemia in a cohort of subjects with and without T2D, hypothesizing that these protein levels would be further elevated during hypoglycemia in T2D subjects. Methods: A prospective, parallel study was conducted in individuals with T2D (n=23) and controls (n=22). Hypoglycaemia ( Results: No changes from baseline in serum levels of the four amyloid-related proteins were seen in subjects with or without T2D, either at the time of hypoglycemia or at 24-hours post-clamp. Conclusions: Induced hypoglycemia is not associated with a significant increase in serum levels of amyloid-related proteins. Thus, no clear mechanistic link based on serum proteins between T2D-related hypoglycemic episodes and Alzheimer’s disease emerged from this study, although it is important to consider that protein levels in the cerebrospinal fluid may differ.
