  • The Value of Serum KL-6 Level as An Diagnostic Indicator in Patients with Interstitial Lung Diseases

    ObjectiveTo determine the diagnostic value of serum KL-6 level in patients with interstitial lung diseases (ILD). MethodsAll the ILD patients enrolled were hospitalized from April 2013 to April 2014. Patients with other pulmonary diseases and healthy subjects were chosen as control groups simultaneously. Serum KL-6 concentrations were measured by chemiluminescent enzyme immunoassay. The association with serum KL-6 level and pulmonary function was analyzed. ResultsThere were 149 ILD patients, 155 patients with other pulmonary diseases, and 64 healthy subjects. The average serum levels of KL-6 were (1 801.86±2 831.36) U/mL, (267.00±124.41) U/mL, (201.28±81.18) U/mL in the patients with ILD, the patients with other pulmonary diseases and the healthy controls, respectively. The sensitivity and the specificity of the serum KL-6 for the diagnosis of ILD was 83.89% and 92.24% respectively when the cut-off level was set at 500 U/mL. The Kappa value was 0.767 (P < 0.001). The best cut-off value of KL-6 was 469.5 U/mL. Serum KL-6 levels in the patients with ILD were significantly higher compared with the patients with chronic obstructive pulmonary disease, pneumonia, tuberculosis, bronchiectasis and the healthy controls, respectively (all P < 0.001). The KL-6 levels in the pulmonary alveolar proteinosis patients were significantly higher compared with the patients with cryptogenic organizing pneumonia (COP), the patients with idiopathic pulmonary fibrosis (IPF) and the patients with connective tissue disease (CTD-ILD) (all P < 0.001). While the KL-6 concentration in IPF and CTD-ILD were significantly higher than that in COP (P=0.003 and P=0.008, respectively). Significant negative correlations were found between the levels of serum KL-6 and vital capacity as a percentage of the predicted value, forced vital capacity as a percentage of the predicted value, forced expiratory volume in one second as a percentage of the predicted value and carbon monoxide diffusing capacity as a percentage of the predicted value (all P < 0.001). Follow-up study showed the levels of serum KL-6 were consistent with clinical efficacy. ConclusionSerum KL-6 level is a reliable serum marker for ILD, and is related with the severity of disease and clinical efficacy.

  • KL-6联合肺功能在多发性肌炎/皮肌炎合并间质性肺疾病中的应用价值

    目的 探讨血清KL-6和肺功能检测在多发性肌炎(polymyositis,PM)/皮肌炎(dermatomyositis,DM)合并间质性肺疾病(interstitial lung disease,ILD)中的临床应用价值。方法 采用回顾性分析,纳入初发PM/DM患者(n=64)临床资料,分为间质肺组(n=40)和无间质肺组(n=44),另选健康对照组40例,比较三组患者血清KL-6水平及肺功能在两组的差异并分析其在PM/DM-ILD组中的应用价值。结果 间质肺组患者KL-6水平明显高于无间质肺组(P<0.01);间质肺组患者VC%pred、MVV%pred、FEV1%pred、DLCO%pred、DLCO/VA%pred、TLC%pred均低于无间质肺组(P均<0.05);ROC曲线分析得出PM/DM患者中血清KL-6诊断ILD敏感性为84%,特异性为87.5%,DLCO%pred诊断ILD的敏感性为97.7%,特异性为57.5%,而二者联合检测敏感性为90.5%,特异性为82.5%;间质肺组血清KL-6与VC%pred、MVV%pred、FVC%pred、FEV1%pred、DLCO%pred成反比,与FEV1/FVC%pred成正比(P均<0.05);PM/DM发生ILD的危险因素:AST降低、KL-6升高及DLCO%pred降低。结论 PM/DM患者联合检测血清KL-6和肺弥散功能可提高ILD诊断效能,KL-6和肺功能可能预测ILD的发生及疾病活动度,可指导临床。
