EARLY UNDIFFERENTIATED CONNECTIVE TISSUE DISEASE

本研究的目的是评估EUCTD患者以确定 哪些历史、生理和血清学特征可以预测 这一疾病过程的进化。这项研究的另一个目的是 评估类风湿性关节炎、系统性红斑狼疮患者 少红斑症、多发性肌炎和进行性系统性硬化症 超过12个月的持续时间来确定10年内的总体预后 以及是否有任何历史、生理和血清学特征 对结果的预测。

The purpose of this study is to evaluate patients with EUCTD to determine what historical, physical, and serologic features are predictive of the evolution of this disease process. The other purpose of this study is to evaluate patients with rheumatoid arthritis, systemic lupus erythematosus, polymyositis, and progressive systemic sclerosis of less than 12 months duration to determine the overall prognosis over a 10 year period and whether any historical, physical, and serologic features are predictive of outcome.
