Background:
Growth hormone (GH) secretion is increased in pre-pubertal children with type 1 diabetes and GH excess produces insulin resistance. Early-morning insulinopenia contributes to lower insulin-like growth factor (IGF-I) levels and to GH hypersecretion.
Objective:
To evaluate differences in GH/IGF-I axis of pre-pubertal children with type 1 diabetes treated with glargine or detemir as long-acting insulin analogues, which was the main outcome measure, and to compare insulin effects in obtaining good metabolic control.
Subjects:
Children with type 1 diabetes.
Methods:
This was a 32-week, randomized, open-label, two-period, cross-over comparison between bedtime glargine and twice-daily detemir insulin, involving pre-pubertal children in care at a diabetes pediatric centre. After a 8-week-run-in period subjects were randomized to bedtime glargine or twice-daily detemir insulin administration. After a 12-week period treatments were inverted and continued for additional 12 weeks.
Results:
Overall, 15 pre-pubertal children (53.3% males, mean age 8.6±1.5 years, duration of diabetes 4.2±1.5 years) completed the study. Groups did not differ for GH/IGF axis and HbA1c levels. Treatment with glargine was associated with lower fasting glucose values than treatment with detemir (8.1±1.5 vs. 8.2±1.7 mmol/L, p=0.01). Incidence rate of hypoglycemia was not different between insulin treatments (IRR=1.18, 95%CI 1.00-1.38; p=0.07). Detemir treatment was associated with a higher increase in body weight (p=0.008) and height (p=0.02) when compared with glargine.
Conclusion:
Detemir and glargine not show significant differential effects on the GH/IGFI axis. The greater weight gain and height associated with detemir treatment, apparently not related to the level of pubertal growth, deserve further investigation.
