Analysis of misdiagnosis of 14 patients with polymyositis (PM/DM) complicated by interstitial lung disease

目的 提高对多发性肌炎 皮肌炎 (PM DM )合并肺间质病变 (ILD)的认识。方法 对 14例PM DM合并ILD进行回顾性临床分析。结果 14例中男女之比为 8∶6 ,平均年龄 4 3.7岁 ,平均误诊时间 6 .2个月 ,误诊为呼吸系统疾病 2 2例次 ,误诊为感染性疾病 2 1例次。结论 误诊原因 :年龄及性别反差 ;ILD症状在前为主掩盖了PM DM ;检查手段特异性和敏感性差。电视引导下经胸腔镜 (VATS)活检 ,可提高PM

Objective To know more about polymyositis (PM/DM) complicated by interstitical lung disease (ILD).Methods Clinical analysis of 14 patients with PM/DM complicated by inters titial lung disease (ILD).Results Male to female ration was 8∶6,averge age is 43.7,and average duration of misdiagnosis was 6.2 months,there were 22 patients misdiagnosed for respiratory system diseases and 21 patients for inflammation diseases.Conclusion Misdiagnoses are unusual between age and sex.The syndromes of ILD,which occur before those of PM/DM easily.limitations of acknowledge of PM/DM,the low specificity and sensitivity of examination.Biopsy through video-assistant thorascope (VATS) can increase the diagnoses of PM/DM with ILD.
