A comparison of the use of premixed insulins in pen-injectors with conventional patient-mixed insulin treatment in children and adolescents with IDDM.: Is there a decreased risk of night hypoglycemia?

Insulin injection is a problem in pediatric and adolescent age, and premixed insulin therapy given in pen-injectors (Novopen II(R)) is expected to increase compliance. Compliance with treatment and safety of this kind of insulin substitution was investigated in 20 IDDM patients (8.2-19.6 years old). The study was of randomized cross-over design and its duration was 6 (2x3) months. Metabolic parameters were compared between premixed insulin therapy via pen-injector and patient-mixed insulin therapy via conventional syringe, and no differences were observed except for the postponing of night hypoglycemic attacks to 07.00 a.m. during premixed insulin therapy. No technical or medical problems occurred. Patients were more satisfied with the new therapy regimen as determined by questionnaire. We concluded that this kind of insulin substitution is safe in pediatric and adolescent IDDM patients.
