Glycaemic control and hypoglycaemia in children, adolescents and young adults with unstable type 1 diabetes mellitus treated with insulin glargine or intermediate-acting insulin.

In this open study of clinical practice, 142 paediatric patients with type 1 diabetes mellitus (>1 year duration), stratified by age, received prandial insulin (regular or lispro) and either once daily insulin glargine (GLAR; n=74), titrated to target fasting blood glucose (FBG) levels 4.4-7.8 mmol/l, or NPH/semilente insulin (NPH insulin, administered once, twice or three times daily; n=68), titrated to target FBG 4.4-8.9 mmol/l. Both groups were treated for 20 +/- 10 months. HbA(1c) significantly increased in GLAR (7.3 +/- 1.0% to 7.6 +/- 1.1%; p = 0.003) and NPH/semilente insulin (7.7 +/- 1.6% to 8.3 +/- 1.5%; p = 0.0001) treated patients. The incidence of symptomatic hypoglycaemia was comparable between GLAR versus NPH/semilente insulin at endpoint (2.19 vs. 1.94 episodes/week); however, the overall incidence of severe hypoglycaemia was significantly lower with GLAR versus NPH/semilente insulin (0.14 vs. 0.73 events/patient-year; p = 0.002). The daily insulin dose was similar between the treatment groups; however, perceived quality of life (QoL) was better with GLAR. GLAR is associated with equivalent glycaemic control, less severe hypoglycaemia and improved QoL compared with NPH/semilente insulin.
