Juvenile systemic sclerosis (jSSc) is an orphan autoimmune disease. Several publications in adults looked at the differences between limited and diffuse subtypes. There is rarity of data regarding this topic in pediatric jSSc. The juvenile scleroderma inception cohort (www.juvenile-scleroderma.com) is a prospective standardized register for patients with jSSc.
Patients with jSSc were included worldwide into the juvenile scleroderma inception cohort. We compared the demographics and clinical features of the ljSSc and djSSc. Data of the juvenile systemic sclerosis inception cohort have been contributed to the DeSScipher project which was funded by a grant of theEuropean Community’s Framework Programme 7 under grant agreement N° 305495.
Up till now 50 patients were enrolled, 34 (68%) with djSSc and 16 (32%) with ljSSc. 5 in the diffuse (15%) and 3 in the limited subtype (19%) had an overlap feature. The mean follow up of the patients in the cohort was 6.4 years in the djSSc and 5.5 years in ljSSc. 74% in the djSSc and 75% in the ljSSc group were female. The mean age at the onset of Raynaud´s Phenomenon was 8.4 years in the jdSSc and 10.8 years in ljSSc group (p=0.061) while the mean age at the onset of the first non-Raynaud presentation was 8.8 years in djSSc and 11.6 years ljSSc (p=0.010). At the time of the inclusion the mean modified Rodnan Skin Score was 20.4 in the djSSc and 8.9 in ljSSc (p=0.002). 72% in jdSSc and 56% in the ljSSc of patients (p=0.35) had already capillary changes, but 64% in djSSc and only 26% in ljSSc (p=0.015) had already history of ulcerations and 33% presented with active ulceration in the djSSc and 6% in the ljSSc (p=0.074). 71% of djSSc and 68 % of ljSSc had cardiopulmonary involvement. Four patients had pulmonary hypertension. 3 of them had djSSc. 44% in djSSc and 19% in ljSSc group (p=0.117) showed signs of interstitial lung disease on imaging. Four patients had renal involvement, 3 of them had djSSc, no renal crisis was reported. 47% in the djSSc and 25% in the ljSSc (p=0.216) had gastrointestinal involvement. Around 76% in djSSc and 81% in ljSSc had musculoskeletal involvement. Anti-Scl 70 positivity was found in 10/27 (37%) of djSSc and 5/13 (38%) in ljSSc. Only 2 patients and only in the djSSc group had anticentromere antibody.
We present the data on the first 50 patients with jSSc included in our cohort. Patients with djSSc and ljSSc differ in several characteristics. Patients with djSSc were younger at onset, had more often capillary changes and active ulcerations, pulmonary hypertension and renal involvement. The characteristics of the pediatric subtypes differs from adults with SSc.
