Abstract:

Aims: Identifying age-dependent basal rates in type 1 diabetic children treated with continuous subcutaneous insulin infusion (CSII).

Methods: CSII-treated children with type 1 diabetes exhibiting insulin requirement > 0.5U/kg and glycated haemoglobin (HbA1c) < 8%. The study population was composed of 198 Caucasian children (111 girls) with mean age of 9.8 ± 3.8 years, mean duration of diabetes of 4.3 ± 3.1 years and mean HbA1c value of 6.7 ± 0.7%. Data were evaluated for four age groups (0-6; 6-9; 9-12, 12-18 years). Basal rates records were downloaded from pump memory. HbA1c, weight, height were measured at scheduled visits.

Results: Significant differences in the average hourly basal rate between groups were observed: I gr. 0.14 versus II gr. 0.24 versus III gr. 0.39 versus IV gr. 0.72 units/h; p < 0.0001. The average hourly basal rate correlated with age, body weight, BMI, diabetes duration and total insulin daily dose. Insulin peaks were observed for: I gr. - before midnight, II gr. - before midnight and in the early morning, gr. III and IV - in the early morning.

Conclusion: Basal insulin infusion rate profiles in well-controlled paediatric patients on CSII reflect the age-dependent amount of basal insulin (20-40%) and affect circadian distribution of insulin needs.
