Pulmonary fibrosis refers to the development of diffuse parenchymal abnormalities in the lung that cause dyspnea, cough, hypoxemia, and impair gas exchange, ultimately leading to respiratory failure. Though pulmonary fibrosis can be caused by a variety of underlying etiologies, ranging from genetic defects to autoimmune diseases to environmental exposures, once fibrosis develops it is irreversible and most often progressive, such that fibrosis of the lung is one of the leading indications for lung transplantation. This review aims to provide a concise summary of the recent advances in our understanding of the genetics and genomics of pulmonary fibrosis, idiopathic pulmonary fibrosis in particular, and how these recent discoveries may be changing the clinical approach to diagnosing and treating patients with fibrotic interstitial lung disease.
肺纤维化是指肺部弥漫性实质异常导致呼吸困难、咳嗽、低氧血症和气体交换受损,最终导致呼吸衰竭。尽管肺纤维化可能由多种潜在病因引起,包括遗传缺陷、自身免疫性疾病和环境暴露等,但一旦纤维化形成,它就是不可逆转的,而且通常是进行性的,因此肺纤维化是肺移植的主要指征之一。本文旨在简要总结肺纤维化(特别是特发性肺纤维化)遗传学和基因组学研究的最新进展,以及这些新发现如何改变我们诊断和治疗纤维性间质性肺疾病患者的临床方法。
