RESUMEN
AIMS: To compare glycaemic control and risk of hypoglycaemia of twice-daily insulin detemir with once-daily insulin glargine in subjects with Type 1 diabetes. METHODS: In this 26-week, multicentre, open-label, parallel-group trial, 320 subjects with Type 1 diabetes received either insulin detemir twice daily or insulin glargine once daily. each in combination with premeal insulin aspart. RESULTS: After 26 weeks, HbA(1c) had decreased from 8.8 to 8.2% in the insulin detemir group and from 8.7 to 8.2% in the insulin glargine group. Home-measured fasting plasma glucose (PG) was lower with insulin glargine than with insulin detemir (7.0 vs. 7.7 mmol/l, P < 0.001). The overall shape of the home-measured nine-point PG profiles was comparable between treatments (P = 0.125). Overall, there was no significant difference in within-subject variation in PG (P = 0.437). Within-subject variation in predinner PG was lower with insulin detemir than with insulin glargine (P < 0.05). The overall risk of hypoglycaemia was similar with no differences in confirmed hypoglycaemia. However, the risk of severe and nocturnal hypoglycaemia was 72% and 32%, respectively, lower with insulin detemir than with insulin glargine (P < 0.05). Body weight gain was not significantly different comparing insulin detemir and insulin glargine (0.52 kg vs. 0.96 kg, P = 0.193). CONCLUSIONS: Treatment with twice-daily insulin detemir or once-daily insulin glargine, each in combination with insulin aspart, resulted in similar glycaemic control. The overall risk of hypoglycaemia was comparable, whereas the risks of both severe and nocturnal hypoglycaemia were significantly lower with insulin detemir.

AIMS: This study compared the effect of insulin detemir on glycaemic control (HbA(1c), fasting plasma glucose and variability thereof) with that of Neutral Protamine Hagedorn human isophane (NPH) insulin, both combined with insulin aspart, in children with Type 1 diabetes mellitus, and compared the safety of these treatments. METHODS: In this 26-week, open-label, randomized (2 : 1), parallel-group study, 347 (140 prepubertal and 207 pubertal) children with Type 1 diabetes, aged 6-17 years, received insulin detemir (n = 232) or NPH insulin (n = 115) once or twice daily, according to the prestudy regimen, plus premeal insulin aspart. RESULTS: The mean HbA(1c) decreased by approximately 0.8% with both treatments. After 26 weeks, the mean difference in HbA(1c) was 0.1% (95% confidence interval -0.1, 0.3) (insulin detemir 8.0%, NPH insulin 7.9%). Within-subject variation in self-measured fasting plasma glucose was significantly lower with insulin detemir than with NPH insulin (SD 3.3 vs. 4.3, P < 0.001), as was mean fasting plasma glucose (8.4 vs. 9.6 mmol/l, P = 0.022). The risk of nocturnal hypoglycaemia (22.00-07.00 h) was 26% lower with insulin detemir (P = 0.041) and the risk of 24-h hypoglycaemia was similar with the two treatments (P = 0.351). The mean body mass index (BMI) Z-score was lower with insulin detemir (P < 0.001). CONCLUSIONS: Basal-bolus treatment with insulin detemir or NPH insulin and premeal insulin aspart in children and adolescents with Type 1 diabetes mellitus improved HbA(1c) to a similar degree. The lower and more predictable fasting plasma glucose, lower risk of nocturnal hypoglycaemia and lower BMI observed with insulin detemir are clinically significant advantages compared with NPH insulin.
