[Correlation of cutaneous blood microcirculation parameters with biological age in diabetic patients.]

It has been established that the age together with the number of chronic diseases cause the decrease of the reactivity of the microcirculatory bed. This study aims to evaluate the relationship between cutaneous microcirculation parameters and biological and chronological age of patients with diabetes mellitus. 11 diabetic patients (median age 57 (51; 64) years) were examined in course of this study; biological age was figured by Aging.AI3.0 calculator. Cutaneous microcirculation parameters were measured by laser Doppler flowmetry with an occlusion-heating test. Spearman's rank correlation coefficients were calculated to analyze the relationships between quantitative parameters. Significant multiple negative correlations of biological age and microvascular reactivity indices on exposure to both heat and occlusion (correlation strength from -0,618, to -0,97, p<0,05) were found. Diabetic patients have decreased microvascular reactivity that is more associated with biological age than with chronological age.

[Study of new capacities in the evaluation of glycemic control in patients with type 2 diabetes].

The purpose of the study was to comprehensively analyze glycemic control in type 2 diabetes (T2D) patients who were first given glucose-reducing therapy. Glidiab MB and Diabeton MB caused a comparable reduction in glycemic control parameters: the level of HbA1c, fasting glycemia, and mean glycemic levels as shown by the results of its continuous glucose monitoring system (CGMS) study. The lower glycemic level was not accompanied by weight gain and it improved lipid spectrum parameters. The readings of monthly self-control of glycemia were transformed to its deviation from the goal range (ADRR) that and the hyper- and hypoglycemia indices calculated from the continuous glycemic control were used to evaluate glycemic lability not reflected by HbA1c. In this connection ADRR may be used to evaluate the efficiency of sugar-reducing therapy and in the examined groups it proved to be low, which generally reflects the stable course of the disease in new cases of T2D. The mean glycemic value calculated from CGMS data virtually coincides with the mean glycemia estimated from glycemic self-control readings both on the day of continuous glucose monitoring and in the month to come before and after CGMS study. In this connection the latter is justified only when the continuous glycemic curve undergoes a complex analysis. The complex analysis of the continuous glycemic curve includes symmetrization of the continuous glycemia scale; calculation of hyper- and hypoglycemic indices, hourly diurnal hyperglycemic index and hourly glycemic variations (Poincare method). The use of this procedure could compare the glucose-reducing effect of the two drugs within the framework of a short-term study.
