    Abstract:
    AIM: To compare different administration times of insulin detemir (IDet) in patients with type 1 diabetes and poor metabolic control. MATERIAL AND METHODS: This 24-week open study included 39 people with type 1 diabetes mellitus (DM) randomized to one injection of IDet before lunch (mean 14.24 + or - 00.36 (+ or - SD) h) or at bedtime (23.19 + or - 0.42 h). Whenever target glycemia levels were not reached, the regimen was switched to insulin therapy with two injections (IDet-12h). Insulin aspart was used before main meals. RESULTS: At week 24, only 12.2% of patients remained in the IDet bedtime group and 30.3% in the IDet before lunch group. The remaining 57.5% joined the IDet-12h group. There were no differences between the IDet before lunch and IDet bedtime groups. A subanalysis including the three groups demonstrated better metabolic control in the IDet before lunch group (glycosylated hemoglobin (HbA1c) 7.1 + or - 0.2 vs. 7.6 + or - 0.4 and 8.1 + or - 0.2% in IDet before-lunch, IDet bedtime and IDet-12h, respectively; p<0.05). An HbA1c value below 7% was achieved in 30.3% of the patients: 15.2% in the IDet before-lunch group, 3.3% in the IDet bedtime group and 12.2% in IDet-12h group. Quality of life did not differ among treatment groups. CONCLUSIONS: One injection of IDet administered before lunch could improve metabolic control. However, most patients required two injections of IDet.
