摘要:

目的 分析空军军医大学唐都医院风湿免疫科多发性肌炎(PM)/皮肌炎(DM)患者并发间 质性肺病(ILD)的危险因素,构建临床预测模型。方法 2015 1 1日至2021 1 1日空军军医大 学唐都医院379 PM/DM 住院患者纳入研究,将其分为对照组(PM/DM)和病例组(PM/DM⁃ILD)。回顾性 收集整理患者的临床病例资料,采用 logistic 回归总结 PM/DM⁃ILD 的危险因素,利用 R 软件构建临床预测 模型。结果 病例组患者的年龄、关节痛、发热、技工手、雷诺现象、胸闷、气短、咳嗽、咳痰发生情况,红细 胞沉降率(ESR)、血清铁蛋白(FER)、癌胚抗原(CEA)、糖类抗原 153(CA153)水平,抗 Jo⁃1 抗体、抗 Ro52 抗体、抗 MDA5 抗体阳性率高于对照组,血清白蛋白(ALB)水平低于对照组(P < 0.05)。logistic 回归分 析显示,年龄、发热、技工手、雷诺现象、铁蛋白(FER)水平、癌胚抗原(CEA)水平、血清白蛋白(ALB)水 平、抗 Jo⁃1 抗体、抗 Ro52 抗体、抗 MDA5 抗体为 ILD 发生的危险因素(P < 0.05)。构建的临床预测模型的 AUC 0.899(95%CI:0.864 ~ 0.934),敏感性为 79.5%,特异性为 86.4%。结论 年龄大、发热、技工手、雷 诺现象,铁蛋白(FER)水平、癌胚抗原(CEA)水平升高,血清白蛋白(ALB)水平降低,抗 Jo⁃1 抗体、抗 Ro52 抗体、抗 MDA5 抗体阳性为 PM/DM⁃ILD 发生的危险因素,本研究构建的模型可以较好地预测 PM/DM⁃ILD 发生,对临床早期防治工作具有一定的参考价值。

Abstract:

Objective To analyze the risk factors for interstitial lung disease (ILD)in hospitalized patients with polymyositis(PM)or dermatomyositis(DM)and to establish a clinical prediction model. Methods 379 in patients with PM or DM in Tangdu Hospital of Air Force Military Medical University from January 1,2015 to January 1,2021 were included in the study and they were divided into a control group(PM/DM)and a case group(PM/DM⁃ILD). The clinical data on the patients were retrospectively collected. The risk factors of PM/DM⁃ ILD were summarized by binary logistic regression. A clinical prediction model was constructed by using the R software. Results The patients′ age was older;the incidences of joint pain,fever,mechanic′s hand,Raynaud′s phenomenon,chest tightness,shortness of breath,cough and expectoration were greater;and erythrocyte sedimen⁃ tation rate(ESR),serum ferritin(FER)and levels of carcinoembryonic antigen(CEA),carbohydrate antigen 153(CA153),anti⁃Jo⁃1 antibody,anti⁃Ro52 antibody and anti⁃mda5 antibody were higher in the control group than in the control group;while level of serum albumin(ALB)was lower(P < 0.05). Binary logistic regression analysis showed that age,fever,mechanic′s hand,Reynolds phenomenon,FER,CEA,serum albumin(ALB), anti⁃Jo⁃1 antibody,anti⁃Ro52 antibody and anti⁃mda5 antibody were the risk factors of ILD(P < 0.05). The AUC of the constructed clinical prediction model was 0.899(95%CI:0.864 ~ 0.934). The sensitivity was 79.5% and the specificity was 86.4%. Conclusions The risk factors of PM/DM⁃ILD are old age,fever,mechanic′s hand,Reyn⁃ olds phenomenon,increased levels of FER and CEA,a decrease in serum albumin(ALB),and positive anti⁃Jo⁃1 anti⁃Ro52 and anti⁃mda5 antibodies. The model constructed in this study can better predict the occurrence of PM/ DM⁃ILD,and it has certain reference value for early clinical prevention and treatment.
