Circulatory system in children with localized scleroderma.
The circulatory system was studied in 43 children (ages 3-18 years, mean 10.6 years; 32 girls, 11 boys) suffering from localized cutaneous forms of scleroderma. The following studies were undertaken: general pediatric examination, cardiologic examination including routine electrocardiogram (ECG), 24-h Holter ECG monitoring, echocardiography plus Doppler study, and a treadmill exercise test. Three children found to have congenital heart malformations were excluded from the study. Children with localized scleroderma were often lighter and shorter than their appropriate controls. The most common ECG abnormality was incomplete right bundle branch block, but other ECG and Holter abnormalities were found as well. Abnormal echocardiographic results were obtained in 16 cases. The abnormalities concerned valvar function (in all heart valves but predominantly in the mitral valve). It was found that the children suffering from scleroderma had different indices than controls for left ventricular mass index, mitral valve function and left ventricular filling. During the exercise test (conducted according to Bruce's protocol) we found no difference between patients and controls.
