INTRODUCTION: Early systemic sclerosis (SSc) is characterized by Raynaud's
phenomenon together with scleroderma marker autoantibodies and/or a scleroderma
pattern at capillaroscopy and no other distinctive feature of SSc. Patients
presenting with marker autoantibodies plus a capillaroscopic scleroderma pattern
seem to evolve into definite SSc more frequently than patients with either
feature. Whether early SSc patients with only marker autoantibodies or
capillaroscopic positivity differ in any aspect at presentation is unclear.
METHODS: Seventy-one consecutive early SSc patients were investigated for
preclinical cardiopulmonary alterations. Out of these, 44 patients and 25
controls affected by osteoarthritis or primary fibromyalgia syndrome were also
investigated for serum markers of fibroblast (carboxyterminal propeptide of
collagen I), endothelial (soluble E-selectin) and T-cell (soluble IL-2 receptor
alpha) activation. RESULTS: Thirty-two of the 71 patients (45.1%) had both a
marker autoantibody and a capillaroscopic scleroderma pattern (subset 1), 16
patients (22.5%) had only a marker autoantibody (subset 2), and 23 patients
(32.4%) had only a capillaroscopic scleroderma pattern (subset 3). Patients with
marker autoantibodies (n = 48, 67.6%) had a higher prevalence of impaired
diffusing lung capacity for carbon monoxide (P = 0.0217) and increased serum
levels of carboxyterminal propeptide of collagen I (P = 0.0037), regardless of
capillaroscopic alterations. Patients with a capillaroscopic scleroderma pattern
(n = 55, 77.5%) had a higher prevalence of puffy fingers (P = 0.0001) and
increased serum levels of soluble E-selectin (P = 0.0003) regardless of marker
autoantibodies. CONCLUSION: These results suggest that the autoantibody and
microvascular patterns in early SSc may each be related to different
clinical-preclinical features and circulating activation markers at presentation.
Longitudinal studies are warranted to investigate whether these subsets undergo a
different disease course over time.
