[Analysis of a continuous 24-hour glycemic curve by the symmetrization method]

The study included 18 patients (10 females and 8 males) with a not less than 2 year-history of type 1 diabetes (T1D), who had received insulin therapy since its diagnosis was established. The patients ' mean age was 32.9± 13.0 years; the mean duration of TID was 15.1+11.5 years; the mean daily dose of insulin was 40.1+16.0 units; the mean level of glycosylated hemoglobin (HbAJ was 9.4±2.1% (the normal value 4.4-4.9%). The glycemic curve symmetrization method proposed for statistical analysis of glycemic self-control is also quite suitable for the statistical monitoring of a continuous daily glycemic curve. The high and low glycemic indices calculated from the symmetrized glycemic data correlate well with the level of HbAk and with the duration of hypoglycemia and hyperglycemia and hence they may be used as additional criteria for a risk of diabetes complications. The criteria, calculated from the symmetrized data of glycemia for the risk of hyper- and hypoglycemia, adequately reflect the behavior of a continuous glycemic curve and may be used as integral indices of the efficiency of glucose-reducing therapy in clinical practice.
