Abstract: | Patients with systemic sclerosis (SSc) are at a high risk of the development of ischaemic digital ulcers (DUs) that can be complicated with infections, gangrene, and osteomyelitis. The aim of this study is to evaluate the role of endostatin in scleroderma DUs.In total, 90 SSc patients were enrolled in this study. Serum endostatin levels and DU assessment were determined in all SSc patients. The serum levels of endostatin significantly increased with progression of capillaroscopic damage (P < .01). The serum levels of endostatin are significantly (P < .05) higher in SSc patients with new DUs than in SSc patients without new DUs (127 ± 31.1 ng/mL vs 116.3 ± 39.7 ng/mL). The Receiver Operating Characteristic (ROC) curves demonstrated good accuracy of new DU prediction for the serum level of endostatin (0.70, P < .01 95% confidence interval (CI) 0.59‐0.81]). Using a cut‐off value of 116 ng/mL, the odds ratio was 2.609 (CI 1.075‐6.330, P < .05). The serum levels of endostatin are significantly (P < .01) higher in SSc patients with infected DUs than in SSc patients without infected DUs (139.2 114.6‐340.91] ng/mL vs 117.5 64.3‐163.9] ng/mL). Serum levels of endostatin are higher in patients with DUs, especially in those with infected DUs. |
