title: Cardiovascular assessment of asymptomatic patients with juvenile-onset localized and systemic scleroderma: 10 years prospective observation.
abstract: OBJECTIVE
  The aim of the present study was non-invasive evaluation of the cardiovascular system in asymptomatic young adult patients with juvenile localized scleroderma (JLS) and juvenile systemic sclerosis (JSS).
  
  
  METHODS
  A group of 34 consecutive children with scleroderma were prospectively observed in the study. The control group (CG) consisted of 20 healthy subjects. In each subject 12-lead electrocardiographic, echocardiographic, ECG Holter, and ambulatory blood pressure monitoring examinations were performed at the baseline visit and after 10 years. Additionally, B-type natriuretic peptide (BNP) concentrations were measured after 10 years.
  
  
  RESULTS
  Examinations were performed in 13 patients with JLS and 15 with JSS at the final visit. Two children had died (one from each group). Four patients were alive but refused the final visit. After 10 years, a higher prevalence of ventricular extrasystoles (p = 0.01) and an elevated pulmonary arterial pressure (JLS: p = 0.04, JSS: p = 0.03) were observed in both groups, but in comparison with the controls there was no significant difference at the final visit. In JLS patients more cases of left ventricle diastolic dysfunction, hypertension, and sinus tachycardia were diagnosed at the final visit (p ≤ 0.05). More atrioventricular block episodes in both groups of scleroderma patients were observed. Over the 10 years, arterial hypertension was diagnosed in three patients from the JLS group and in two with JSS. There were no significant differences in BNP concentrations at the final visit.
  
  
  CONCLUSIONS
  The results of the present study show that juvenile scleroderma seems to be more benign than adult-onset disease. This observational study shows subclinical, not severe, cardiac abnormalities in adult patients with juvenile-onset disease.
