【摘要】 目的 :探讨类风湿性关节炎患者早期肺损害临床诊断方法。方法 :对 2 7例无呼吸系统症状、2 1例有明显呼吸系统症状类风湿性关节炎患者行动脉血气分析、肺CT、肺功能检查 ,比较 3种方法对肺损害的诊断价值。结果 :无呼吸系统症状 2 7例 ,动脉血气分析、肺CT正常 ,肺功能检查VC、FVC正常 ,DLCO 降低 ;有呼吸系统症状 2 1例 ,血气分析PO2 降低 ,肺功能检查VC、DLCO降低 ,CT表现为肺间质病变、支气管扩张、胸膜病变。结论 :血气分析、CT、肺功能检查 3种方法比较 ,肺功能检查DLCO最早出现异常 ,对于类风湿性关节炎早期肺损害诊断有重要意义更多还原

【Abstract】 Objective:To evaluate the methods for the early diagnosis of lung injury in rheumatoid arthritis(RA)patients. Methods:27cases without respiratory symptoms and 21 cases with respiratory symptoms were studied by means of CT, blood gas analysis and pulmonary function tests. Results:27 cases without respiratory symptoms showed only decreased DL CO while 21 cases with respiratory symptoms showed decreased PO 2,VC and DL CO ,and CT result was abnormal. Conclusion:DL CO is important in the early diagnosis of lung injury in RA patients when PO 2 and CT are normal.更多还原
