类风湿关节炎合并骶髂关节改变患者临床特点分析

目的 提高对类风湿关节炎合并骶髂关节改变的认识。方法 收集13例合并骶髂关节改变的类风湿关节炎患者及67例不合并骶髂关节改变的类风湿关节炎患者的临床和实验室检查资料，并加以分析比较。结果合并骶髂关节改变的类风湿关节炎患者，以男性为主，多以桡腕关节炎首发，下肢关节大多呈非对称性炎症改变，人类白细胞抗原(HLA)-B27阳性，或同时伴有类风湿因子(RF)阳性。结论 类风湿关节炎患者如出现臀部和／(或)下背部症状，要考虑合并骶髂关节改变，可做HLA-B27和骶髂关节CT检查。

Clinical feature of patients with rheumatoid arthritis combin sacroiliacpathy

Objective To improve recognition of sacroiliacpathy in patients with rheumatoid arthritis (RA). Methods Clinical features and laboratory markers of 13 patients with RA combined sacroiliacpathy were compared with 67 RA patients without sacroiliacpathy. Results Male was predominate in RA patients with combined sacroiliacpathy. HLA-B27 or/and RF positive was higher in combined case. Radiocarpal onset and unsymmetrical lower extremity arthritis was more frequent in combined cases. Conclusion When RA patients have buttocks and/or lumbar symptoms, sacroiliacpathy should be considered. HLA-B27 typing and CT should be applied to find early changes.
