    摘要:

    目的：评估中性粒细胞与淋巴细胞比值（neutrophil-to-lymphocyte ratio，NLR）和全身免疫炎症指数（systemic immune- inflammation index，SII）在预测抗黑色素瘤分化相关基因5阳性皮肌炎（anti-melanoma differentiation-associated gene 5-positive dermatomyositis，抗MDA5+ DM）患者发展为快速进展型间质性肺病（rapidly progressive interstitial lung disease，RPILD）的预测价值。方法：回顾性分析2019年3月—2023年9月南京医科大学第一附属医院124例抗MDA5+ DM患者的临床和实验室资料，采用 Cox 回归分析确定与 RPILD 发展和病死率相关的独立危险因素。进行受试者工作特征（receiver operating characteristic， ROC）曲线分析，以确定预测不良结局的最佳临界值。结果：124例患者中，36例（29.03%）发生RPILD，39例（31.45%）在随访期间死亡。多因素Cox回归分析发现NLR升高是RPILD的独立危险因素，而SII升高与病死率独立相关。根据ROC曲线确定， NLR＞6.12是RPILD的预测因子，SII＞875.79时死亡风险增加。结论：NLR和SII是抗MDA5 + DM患者简单、经济、可靠的预后指标，为临床管理和风险分层提供了有价值的指导。

    Abstract:

    Objective：To evaluate the predictive value of the neutrophil - to - lymphocyte ratio（NLR）and the systemic immune - inflammation index（SII）in predicting patients with anti - melanoma differentiation - associated gene 5 - positive（anti - MDA5 + ） dermatomyositis（DM）develop into the rapidly progressive interstitial lung disease（RPILD）. Methods：We retrospectively analyzed the clinical and laboratory data of 124 anti - MDA5 + DM patients from the First Affiliated Hospital of Nanjing Medical University between March 2019 and September 2023. We identified independent risk factors associated with the development and mortality of RPILD with the Cox regression analysis，and determined the optimal cut-off values for predicting adverse outcomes with the receiver operating characteristic（ROC）curve analysis. Results：Among the 124 patients，36 patients（29.03%）developed RPILD，and 39 patients（31.45%）died during the follow-up period. The results of multivariate Cox regression analysis showed that the elevated NLR was an independent risk factor for RPILD development，while the elevated SII expression was independently associated with the increased mortality of RPILD. Based on the ROC curve analysis，NLR＞6.12 was a predictor for RPILD，and SII ＞875.79 was associated with increased mortality risk of RPILD. Conclusion：Both NLR and SII are accessible，cost-effective，and reliable prognostic indicators for the prognosis of patients with anti-MDA5+ DM，providing a valuable guidance for clinical management and risk stratification of the disease.
