Capillaroscopy and ECG parameters in children and adolescents with diabetes mellitus type I

Evaluate ECG parameters and detect changes in capillaroscopy parameters in children and adolescents with Diabetes mellitus type 1 (DMT1). ECG and capillaroscopy were performed in 32 children and adolescents (6-15 years old, 17 boys,15 girls) with DMT1. Disease duration - less than 2 years -13, 2-4 years - 10, 5-10 years - 9 cases. The patients were divided into two groups: I group - 12 patients with no complications of DMT1 (in all them duration of disease was less than 2 years), II group - 20 patients with diagnosed cardiac complications of DMT1 (diabetic cardiomyopathy, angiopathy). Additionally 6 of them had diabetic encephalopathy , 4 - diabetic encephalopathy and peripheral neuropathy, 4 - nephropathy and retinal antipathy. Level of glycosides hemoglobin was 8-11%, level of glucose 4 to 15 mmole/L. Control group included 20 healthy children of the same age. In group I ECG is less informative. Hypertrophies of left ventricle and atrium and disorders of repolarization were mainly found in group II. In 62.5% of cases rhythm and conduction disorders were revealed, which were more often in group II. Capillaroscopy changes (pale and cyanotic background, decreasing of the number of capillaries in sight, dilated and contracted diameter, pathological shape and order of capillaries, slow blood flow) were seen both in I and II groups with more prevalence and intensity in the latter one. In children and adolescents with Diabetes mellitus type 1 ECG and capillaroscopy should be performed on the regular basis in order to reveal early changes and start the appropriate treatment in time.
