Juvenile Scleroderma: A Referral Center Experience

This study aims to evaluate the demographic and clinical features, laboratory data, treatment modalities, and outcomes of juvenile systemic sclerosis (JSS) and juvenile localized scleroderma (JLS) patients at a referral pediatric rheumatology center in Turkey.

Medical records of a total of 57 patients, including 29 with JSS (1 male, 28 females; mean age 18.3±3.2 years; range 14 to 27 years) and 28 with JLS (6 males, 22 females; mean age 14.4±4.8 years; range 6 to 23 years), diagnosed betweenJanuary 2006 and Mart 2015 and followed-up for at least six months were evaluated in this retrospective longitudinal study. All medical records were retrospectively analyzed for demographic, clinical, and laboratory findings.

Mean age at disease onset was 9.9±4.2 years and 7.7±3.9 years for JSS and JLS, respectively. Mean ages at diagnosis and at the time of study were lower in JLS: 9.1±3.5 years vs. 11.7±3.7 years and 14.4±4.8 years vs. 18.3±3.2 years, respectively. Mean disease duration was 7.8±5.2 years and 8.0±4.3 years for JSS and JLS, respectively. Among JSS patients, interstitial lung disease was seen in eight (27%), pulmonary hypertension in three (10%), and arrhythmia in one (3%). One JSS patient (3%) died as a consequence of cardiac sclerosis. Corticosteroids with methotrexate were used in 29 JSS patients (100%) and in 21 JLS patients (75%). Patients with vasculopathy were treated with nifedipine (n=18, 62%) and bosentan (n=12, 41%). Internal organ involvement was treated with high-dose cyclophosphamide (n=10, 34%) or biological agent (n=3, 10%).

Close monitoring of internal organ involvement is of great importance in preventing disease-related complications in JSS and JLS. Although rare, vital organ involvement has a devastating effect on prognosis. Biological agents represent an option for patients resistant to standard immunosuppressive treatment.
