Abstract

Rheological tests were performed in four rigorously defined groups of patients with Raynaud's phenomenon: primary family-related (n = 21), primary family-unrelated (n = 30), 'possible scleroderma' (n = 26), and scleroderma (n = 19). Whole blood and plasma viscosity, and hematocrit were significantly higher in the 'possible scleroderma' group. We conclude that the contribution of central rheological abnormalities in the pathogenesis of Raynaud's phenomenon is limited.

雷诺现象中血液的流变特性。
流变学试验在四组严格定义的雷诺氏现象患者中进行:原发性家族相关(n = 21)、原发性家族无关(n = 30)、“可能的硬皮病”(n = 26)和硬皮病(n = 19)。“可能患有硬皮病”组的全血和血浆粘度以及红细胞压积明显更高。我们得出结论,中枢流变异常在雷诺现象发病机制中的作用是有限的。
