OBJECTIVES: Self-management guidelines for nonsevere hypoglycemia (NS-H) in type 1 diabetes recommend 15 g of simple carbohydrates (CHO) at 15-minute intervals. Because automated insulin delivery (AID) preventively reduces or suspends insulin infusion for imminent hypoglycemia, we aimed to determine whether guidelines were excessive during AID.
METHODS: This work was a secondary analysis of NS-H episodes during inpatient single-hormone (insulin) or dual-hormone (insulin and glucagon) AID trials with standardized CHO treatment protocols.
RESULTS: Forty NS-H episodes occurred: 15 during single-hormone arms (2 trials) and 25 during dual-hormone arms (5 trials). At NS-H treatment T0min, plasma glucose (PG) level was 3.1±0.6 mmol/L, corresponding to a sensor value of 3.6±0.6 mmol/L. Fifteen minutes after CHO consumption, PG increased by 0.9±0.8 mmol/L, recovering 45% of episodes to a safe PG of ≥4.0 mmol/L. With repeated CHO consumption, time to recovery was 21.4±15.7 minutes without rebound hyperglycemia; PG 1 hour after initial CHO was 5.9±2.0 mmol/L. Outcome differences between single-hormone and dual-hormone systems were not statistically significant, except for higher insulin and glucagon levels and less repeated treatments in dual-hormone AID. PG and glucagon levels at T0min were positively associated with increase in PG at T15min and negatively associated with time to recovery.
CONCLUSIONS: NS-H self-management CHO 15-g/15-minute guidelines were neither excessive nor optimal during AID. There is a need to examine data with different AID systems to optimize treatment recommendations.
