THE CONTENT OF MICROELEMENTS IN BLOOD SERUM AND ERYTHROCYTES IN CHILDREN WITH DIABETES MELLITUS TYPE I DEPENDING ON LEVEL OF GLYCEMIC CONTROL.

The aim of this paper is to investigate the content of chromium, cobalt and nickel in serum and erythrocytes in children with type 1 diabetes mellitus, depending on the level of glycemic control. The study was conducted on 68 children with type 1 diabetes mellitus. The patients were divided into four groups based on glycemic control. Group I was composed of 9 children with optimal level of glycemic control. Group II - 25 children with suboptimal level of glycemic control. Group III - 34 children with a high risk to life level of glycemic control. Group IV (control group) consisted of 30 healthy children. Compensation state of type 1 diabetes was evaluated according to ISPAD (Consensus for the Management of Type 1 Diabetes Mellitus in Children and Adolescens 2000). The content of trace elements in biological agents was determined by atomic absorbtion spectrophotometry method with C-115M1 mass-spectrophotometer, manufactured by «Selmi» enterprise (Ukraine). It is found that there is a decrease in serum concentrations of chromium and erythrocyte content of cobalt in patients with optimal level of glycemic control. The deficiency of chromium is accompanied by the deficiency of cobalt in patients with suboptimal level of glycemic control. The lower levels of cobalt and nickel are recorded simultaneously, but there is theexcess of chromium in the erythrocytes of these patients. Patients, who suffer from 1 type diabetes mellitus and high risk for life level of glycemic control have considerable polideficiency of cobalt, nickel and chromium in serum.The increasing level of chromium was recorded only in the erythrocytes. The level of glycemic control and the duration of 1 type diabetes mellitus are important in the forecasting of the development of chronic diabetic complications. It is found that the duration of 1 type diabetes mellitus influences the levels of cobalt and nickel in serum mostly, while the level of glycemic control influences the chromium content.
