Improvement in blood glucose fluctuations of insulin-treated type 1 diabetic patients with additional use of acarbose and assessed by continuous blood glucose monitoring program / 中华流行病学杂志

ABSTRACT

Objective To investigate the effect of combined use of insulin and acarbose on glucose excursion in type 1 diabetic patients.Methods 120 cases were randomly divided into control group and observation group.The control group received preprandial ultra-short effect insulin and long-acting insulin before bedtime while the observation group received acarbose 50 mg added to the medicine taken by the control group.Continuous Glucose Monitoring System (CGMS) was used to watch the blood glucose fluctuations.Data related to blood glucose level,glucose excursions after meals and hypoglycemia at night were compared between patients in the two groups.Results The average blood glucose (9.37 ± 1.70) mmol/L,the largest amplitude of glycemic excursions (LAGE) ( 11.42 ± 2.73 ) mmol/L,hyperglycemia-area under curve 0.89 ± 0.54,mean amplitude of glycemic excursions (MAGE) (5.13 ± 2.23) mmol/L,M-value (18.93 ± 11.43) mmol/L and insulin dosage (42.11 ± 14.42)U/day of observation group were significantly lower than in the control group (P＜0.05 ).Glucose excursions after meals and the times( 0.33 ± 0.50 )/day,the maintenance time (43.75 ± 43.50)/min and low glycemic index ( LBGI ) (0.005 ± 0.002 ) mmol/L of hypoglycemia at night were also significantly lower than in the control group,with statistically significant (P＜0.05) differences.Conclusion The blood glucose fluctuation was significantly improved,with the decrease of insulin dosage while both glucose excursions and hypoglycemia at night reduced in patients with typel diabetes mellitus after the acarbose treatment.We suggested that this program deserve further observation.
