Task: Question Generation
Input (English): To assess the serum profile of factors involved in endothelial, T-cell, and fibroblast interplay in patients with Raynaud's phenomenon (RP) associated with nailfold vodeocapillaroscopy (NVC) scleroderma findings and/or systemic sclerosis (SSc) marker autoantibodies, recently labeled as early SSc patients.", 'Serum levels of soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule-1 (sVCAM-1), CCL2, CXCL8, IL-13, IL-33, and transforming growth factor-β (TGF-β) were measured in 24 early SSc patients, 48 definite SSc patients, and 24 osteoarthritis/fibromyalgia controls by multiplex suspension immunoassay. All SSc patients were investigated for the presence/absence of preclinical and clinical organ involvement, SSc marker autoantibodies, and NVC abnormalities.', 'Serum sICAM-1, CCL2, CXCL8, and IL-13 were increased in all SSc patients as compared to controls, and paralleled the severity of the disease subset (early SSc < limited cutaneous SSc < diffuse cutaneous SSc; p\u2009<\u20090.0001). Surprisingly, IL-33 was significantly higher in early SSc patients as compared to both controls (p\u2009<\u20090.01) and definite SSc patients (p\u2009<\u20090.05). In early SSc there were no differences in the investigated markers according to the functional and serological features assessed.
Output (English): Is early systemic sclerosis : serum profiling of factors involved in endothelial , T-cell , and fibroblast interplay marked by elevated interleukin-33 levels?
