Abstract

Object: To investigate whether the prevalence of positive ANA was increased in COPD with interstitial lung abnormality (ILA).

Methods: Patients with COPD from 1 September, 2019 to 31 August, 2022 were consecutively enrolled in this cross-sectional study. The characteristics, PFTs, visual assessment of ILA and emphysema on chest CT, and tests for ANA and CRP were recorded for analysis.

Results: In the study period, 100 patients with COPD were enrolled, with 90 (90.0%) males, aging 69.4 ± 8.3 years. ILA was present in 42% (n = 42) of the patients, with subpleural non-fibrotic ILA being the most common pattern. In patients with ILA, the prevalence of positive ANA was higher (45.2%) as compared to those without ILA (13.3%); between whom the difference in D_LCO was also significant. In patients with positive ANA, the scores of ILA were higher, while FEV₁, D_LCO, D_LCO % predicted, FVC, total lung capacity (TLC), and TLC % predicted were significantly lower, as compared to those with negative ANA.

Conclusion: The presence of ILA in patients with COPD was associated with a higher prevalence of positive ANA. Patients with positive ANA tended to have lower FEV₁, D_LCO and lung volume.

COPD患者肺间质异常与抗核抗体的高患病率有关。

目的：探讨ANA阳性在COPD伴间质性肺异常（ILA）患者中的患病率是否增加。方法：将2019年9月1日至2022年8月31日的COPD患者连续纳入本横断面研究。记录特征、PFTs、胸部CT对ILA和肺气肿的视觉评估以及ANA和CRP的测试以进行分析。结果：在研究期间，100名COPD患者入选，其中90名（90.0%）男性，年龄69.4岁 ± 8.3 年。ILA存在于42%（n = 其中胸膜下非纤维化ILA是最常见的模式。在ILA患者中，ANA阳性的患病率（45.2%）高于无ILA患者（13.3%）；DLCO差异也有显著性。与ANA阴性患者相比，ANA阳性患者的ILA评分较高，而FEV1、DLCO、DLCO%预测值、FVC、总肺活量（TLC）和TLC%预测值显著较低。结论：COPD患者ILA的存在与ANA阳性率较高有关。ANA阳性患者的FEV1、DLCO和肺容量往往较低。
