Evaluation of the presence of endothelial dysfunction in children with Henoch-Schonlein purpura in terms of doppler ultrasound

Abstract

Purpose - to assess the presence of endothelial dysfunction in children with Henoch-Schonlein purpura in terms of Doppler ultrasound. Material and methods. We examined 123 children with Henoch - Schonlein purpura from 1 to 18 years old. Assessment of functional status and vasoregulatory vascular endothelial function was performed using Doppler ultrasound using ultrasound scanner "Philips HDII XE" B-mode sensor linear format in the frequency range from 5 MHz to 15 MHz at rest. The Results. Using doppler ultrasound, we found that the endothelial dysfunction observed in all children with at Henoch - Schonlein purpura. In patients with maximum disease activity index of structural and functional state of the endothelium of the carotid and brachial arteries were 1.3 - 1.5 times more than in healthy children. Also, more severe violations of hemodynamic characteristics of blood flow in the brachial artery (speed reduction) were observed at the III degree of activity and accounted for - Vsp 34,59 ± 3,18 mm / sec, Ved 2,72 ± 0,57 mm / sec, S / D 10 15 ± 0,82.
