背景多发性肌炎/皮肌炎(PM/DM)是一种自身免疫性疾病,有时并发快速进展性间质性肺病(RPILD)。然而,可预测 RPILD 发展的血清和肺部生物标志物仍不清楚。 目的 确定可预测 PM/DM-ILD 患者 RPILD 发展的潜在血清和肺部生物标志物。方法 总共纳入 49 名 PM/DM-ILD 患者。我们测量了 41 种细胞因子/趋化因子、铁蛋白和抗 MDA5 抗体的血清水平,在 RPILD (n = 23) 和非 RPILD (n = 26) 组之间进行比较,并通过随机森林分析按重要性对它们进行排名。为了区分这两组,我们通过逻辑回归分析确定了生物标志物组合。我们还测量了支气管肺泡灌洗液 (BALF) 中 41 种细胞因子/趋化因子的水平。使用免疫组织化学,我们检测了肺组织中 IL-15 的表达。还使用 A549 和 BEAS-2B 细胞研究了 IL-15 的产生。结果 RPILD 组的 IL-15、IL-1RA、IL-6、CXCL10、VCAM-1、抗 MDA5 抗体和铁蛋白血清水平显着高于非 RPILD 组,但 ​​CCL22 水平显着较低。同时,抗MDA5抗体、IL-15、CXCL8、CCL22、IL-1RA和铁蛋白是区分两组的最佳组合。 IL-15 和 CCL22 也是抗 MDA5 抗体阳性患者 RPILD 发展的预测标志物。此外,RPILD 组 BALF 中 IL-15 水平显着升高。肺组织表达IL-15,在A549细胞中受到细胞因子刺激后IL-15增加。结论本研究确定了预测PM/DM-RPILD进展的生物标志物组合,IL-15是预测RPILD发展和反映ILD严重程度的重要细胞因子。
BackgroundPolymyositis/dermatomyositis (PM/DM) is an autoimmune disease that is sometimes complicated with rapidly progressive interstitial lung disease (RPILD). However, serum and lung biomarkers that can predict RPILD development remain unclear.ObjectivesTo determine potential serum and lung biomarkers that can predict RPILD development in patients with PM/DM‐ILD.MethodsIn total, 49 patients with PM/DM‐ILD were enrolled. We measured the serum levels of 41 cytokines/chemokines, ferritin and anti‐MDA5 antibody, compared them between the RPILD (n= 23) and non‐RPILD (n= 26) groups, and ranked them by their importance through random forest analysis. To distinguish the two groups, we determined biomarker combinations by logistic regression analysis. We also measured the bronchoalveolar lavage fluid (BALF) levels of 41 cytokines/chemokines. Using immunohistochemistry, we examined IL‐15 expression in lung tissues. The IL‐15 production was also investigated using A549 and BEAS‐2B cells.ResultsThe RPILD group had significantly higher IL‐15, IL‐1RA, IL‐6, CXCL10, VCAM‐1, anti‐MDA5 antibody and ferritin serum levels than the non‐RPILD group, but it had a significantly low CCL22 level. Meanwhile, anti‐MDA5 antibody, IL‐15, CXCL8, CCL22, IL‐1RA and ferritin were the best combination to distinguish the two groups. IL‐15 and CCL22 were also predictive marker for RPILD development in anti‐MDA5 antibody‐positive patients. Additionally, the RPILD group had significantly high IL‐15 levels in BALF. The lung tissues expressed IL‐15, which increased after cytokine stimulation in the A549 cells.ConclusionThis study identified a combination of biomarkers predicting PM/DM‐RPILD progression, and IL‐15 is an important cytokine for predicting RPILD development and reflecting ILD severity.
