Description of the localized scleroderma subgroup of CARRAnet

Results Data were available on 44 children. 81.8% were female and 88.6% were Caucasian, of which 13.6% were Latino. Mean age at onset was 8.2 years (± 4.0), yet first evaluation by a pediatric rheumatologist was 9.9 years (± 4.2). Reported subtypes were: 34 linear scleroderma (LiScl: 25 trunk/limbs, 9 face/neck), 7 with circumscribed morphea (CM: 5 deep, 2 superficial), 6 with generalized morphea (GenM), 3 with eosinophilic fasciitis (EF), and 1 with pansclerotic morphea. There were 5 cases of mixed morphea (2 CM and LiScl, 1 with facial LiScl and GM, 2 with EF and linear lesions). Eight subjects had new lesions at time of enrollment. Features of active lesions included extension of existing lesions (13), warmth (13), erythematous/violacious color (13), and skin induration at lesion perimeter (10). Damage included subcutaneous atrophy (36), hyperpigmentation (35), dermal atrophy (31), hypopigmentation (19), hair loss (17), muscle atrophy (13), joint contracture (10), limb shortening (5), and hemifacial atrophy(1). Only three patients had extracutaneous manifestations, including two with arthritis. ANA positivity was found in 45% of tested patients, otherwise there were no consistent laboratory or imaging abnormalities. Table 1. Mean physician global assessment was 1.61 (range 08) and mean CHAQ score was 0.19 (0-1.13). On a visual analog scale (0-10), mean parent/subject score of overall well-being was 1.80 (± 1.66) and pain was 1.41 (±2.03). Health related quality of life was reported as excellent in 13, very good in 22, good in 7, and poor in 2 subjects. A worst ever and current ACR functional class > I was reported in 33% and 20.5%, respectively. Medications used are listed in table 2.
