J Rheumatol:原发性干燥综合征的气道和肺实质病变

2020-06-19 xiangting MedSci原创

气道和肺实质疾病在pSS患者很常见,且阻塞性和限制性肺功能障碍并存,后者随着时间的推移趋于恶化。

这项研究旨在评估原发性干燥综合症(pSS)患者肺功能和慢性阻塞性肺疾病(COPD)随时间的进展,以及肺功能、影像学表现、呼吸道症状与pSS临床特征之间的关联,将吸烟状况考虑在内。

既往参加pSS肺部受累横断面研究的40例pSS患者(平均年龄66岁,范围42-81岁,39名女性),平均随访6年后重新进行肺功能评估。随访时,还评估了胸部高分辨率CT(HRCT)和pSS疾病活动性、呼吸道症状和吸烟量。

pSS患者肺总量占预计值百分比(TLC)、残气量(RV)、RV/TLC比和一氧化碳弥散能力(DLCO)显著下降,而从基线到随访1秒率(FEV1/VC)占预计值百分比明显升高。从基线到随访,COPD的比例没有明显变化(38%vs.40%)。分别在38%的患者中发现了支气管受累和间质性肺病的影像学征象。

气道和肺实质疾病在pSS患者很常见,且阻塞性和限制性肺功能障碍并存,后者随着时间的推移趋于恶化。COPD仍很常见。pSS的气道和肺部受累可能被漏诊,因此必须特别注意对pSS患者的肺部受累进行临床评估。

糖尿病时长期存在的高血糖,导致各种组织,特别是眼、肾、心脏、血管、神经的慢性损害、功能障碍。而肺功能损害是糖尿病晚期并发症的新靶点。生物标记物可能有助于鉴别患者是否需要进行功能性呼吸试验。因此,来自西班牙的研究人员探讨了血清表面活性蛋白D(SP-D)和血清表面活性蛋白A(SP-A)是否能作为既往没有肺部病变的肥胖2型糖尿病患者,出现肺损伤时的有效生物标志物。这是一项在肥胖门诊进行的病例对照研究。研
