Abstract

IPF is a progressive fibrotic lung disease with a median survival of 3–5 years post-diagnosis. Fifty cases are diagnosed per 100 000 people in the UK. The incidence has been rising over the last two decades, with no cure at present. Furthermore, considerable heterogeneity exists within the disease course, making management and prognostication challenging. Kraven et al (DOI: 10.1136/thoraxjnl-2021–218563) have identified 3 IPF endotypes, termed clusters, that exhibit statistically significant differences in the GAP index (gender-age-physiology index), mortality and gas transfer (DLCO). 220 patients were identified from three pooled, publicly available blood transcriptomic datasets found on the Gene Expression Omnibus, where intermittently, data such as force vital capacity (FVC) was missing. Cluster one heavily displayed genes correlating to electron transport, cellular respiration and TGFβ. Cluster two demonstrated genes related to DNA repair, cell cycle, and apoptosis. Cluster three expressed genes corresponding to immune responses. Cluster 2 patients had the most favourable outcomes, achieving higher DLCO values, and lower GAP scores. Cluster one had the highest GAP score. Cluster three had the poorest prognosis, being 3.59 times more likely to die than patients in cluster 2. Following this discovery phase, the authors created a validated …

IPF 是一种进行性纤维化肺病,确诊后的中位生存期为 3-5 年。在英国,每 10 万人中就有 50 例确诊病例。在过去的二十年里,发病率一直在上升,目前还没有治愈的方法。此外,病程中存在相当大的异质性,使得管理和预后具有挑战性。Kraven 等人(DOI: 10.1136/thoraxjnl-2021-218563)发现了 3 种 IPF 内型,称为群组,它们在 GAP 指数(性别-年龄-生理学指数)、死亡率和气体转移(DLCO)方面表现出显著的统计学差异。我们从基因表达总库(Gene Expression Omnibus)上公开发布的三个集合血液转录组数据集中确定了 220 名患者,这些数据集间歇性地缺失了力量生命容量(FVC)等数据。第一组大量显示了与电子传递、细胞呼吸和 TGFβ 相关的基因。第二组显示了与 DNA 修复、细胞周期和细胞凋亡有关的基因。第三组显示了与免疫反应相关的基因。第二组患者的预后最理想,DLCO值较高,GAP评分较低。第一组的 GAP 评分最高。第三组患者的预后最差,死亡几率是第二组患者的 3.59 倍。在这一发现阶段之后,作者创建了一个经过验证的...
