Chest:非肺脏累及的肺外结节病临床特点分析!

2018-02-20 xing.T MedSci原创

由此可见,肺脏累及和非肺脏累及结节病患者有显著的人口统计学和性别差异。这些差异反映了以前关于皮肤和肺部累及结节病患者之间的差异,因为皮肤是NPS累及的主要器官。虽然肺脏很可能是肺结节病的主要暴露部位,但在NPS中皮肤受累率很高,表明皮肤是呼吸道外抗原捕获最有利的部位。

相比于肺结节病,不累即肺脏的结节病可能参与其他的免疫病理机制以及与其他人口统计学和临床特征有关。近日,呼吸领域权威杂志chest上针对这一问题发表了一篇研究文章。

该研究是一项对1686例来自于美国两所大学大型结节病门诊的经活检证实的结节病患者的实时临床资料进行的回顾性分析。研究人员比较了肺脏累及和非肺脏累及结节病患者的人口统计学特征和临床表现的差异。只有在正常的胸部成像并且根据目前公认的标准没有肺部受累特征的情况下,才被认为非肺脏累及结节病(NPS)。

研究人员发现8.3%的结节病队列患者符合NPS标准。NPS在白种人患者中比黑人患者更为常见,在女性中比男性更常见。皮肤是最常见的累及器官,可在近一半的NPS患者中观察到皮肤受累。孤立性皮肤结节病是NPS组最常见的器官受累形式(25%),5%以上的NPS患者无其他受累形式。

由此可见,肺脏累及和非肺脏累及结节病患者有显著的人口统计学和性别差异。这些差异反映了以前关于皮肤和肺部累及结节病患者之间的差异,因为皮肤是NPS累及的主要器官。虽然肺脏很可能是肺结节病的主要暴露部位,但在NPS中皮肤受累率很高,表明皮肤是呼吸道外抗原捕获最有利的部位。
