在这篇文章中,我们回顾了特发性肺纤维化(IPF)外周血生物标志物的证据,IPF是一种病因不明的危及生命的纤维化肺病。我们专注于外周血中存在的选定生物标志物,因为它们易于获得,可以纵向测量,并且最有可能实现临床实用性。这篇文章集中讨论了可能直接参与IPF发展的具有机械可接受性的生物标志物,包括KL-6、表面活性蛋白A和D、基质金属蛋白酶(MMP)1和7、CCL 18、VEGF、YKL-40、骨桥蛋白、循环纤维细胞和T细胞。在审查每种生物标志物的证据基础后,我们将其指定为:1)区分IPF与其他间质性肺病的诊断生物标志物,2)与疾病进展或死亡率相关的预后生物标志物,或3)可用作连续监测疾病严重程度的工具的生物标志物。虽然目前还没有经过验证的生物标志物,但对新兴疗法的诊断、预后和疾病过程监测的替代物的需求是巨大的。
In this article, we review the evidence for peripheral blood biomarkers in idiopathic pulmonary fibrosis (IPF), a life-threatening fibrotic lung disease of unknown etiology. We focus on selected biomarkers present in peripheral blood, as they are easy to obtain, can be measured longitudinally, and have the greatest likelihood of achieving clinical utility. This article concentrates on biomarkers with mechanistic plausibility that may be directly involved in the development of IPF, including KL-6, surfactant proteins A and D, matrix metalloproteases (MMP) 1 and 7, CCL18, VEGF, YKL-40, osteopontin, circulating fibrocytes, and T cells. After reviewing the evidence base for each, we designate the biomarkers that may have utility as: 1) diagnostic biomarkers to distinguish IPF from other interstitial lung diseases, 2) prognostic biomarkers that are correlated with disease progression or mortality, or 3) biomarkers that can be used as tools for serial monitoring of disease severity. Although there are no validated biomarkers that are currently available, the need for surrogates of diagnosis, prognosis, and monitoring of disease course with emerging therapies is great.
