摘要
目的了解类风湿关节炎(RA)患者血清涎液化糖链抗原6(KL-6)和白细胞介素33(IL-33)的表达水平,探讨检测血清KL-6和IL-33对RA相关间质性肺病(RA-ILD)的诊断价值。方法选择2022年5月-2023年2月在蚌埠医学院第一附属医院和安徽理工大学第一附属医院风湿科住院并确诊为RA的患者88例,根据肺部CT有无间质性肺病(ILD)分为一般RA组(40例)和RA-ILD组(48例)。所有患者均检测与RA相关的血清学指标,如血清类风湿因子(RF)、红细胞沉降率(ESR)和抗环瓜氨酸肽抗体(抗CCP抗体)等。同时检测上述患者血清KL-6和IL-33水平,分析各项指标与ILD的相关性,通过受试者工作特征(ROC)曲线分析各指标对RA-ILD的诊断效能。结果RA-ILD组患者血清KL-6、IL-33水平显著升高;血清KL-6与ESR、CRP、D-二聚体呈正相关关系,血清IL-33与IgG、球蛋白呈正相关关系。经ROC曲线分析发现,各项指标(RF、ESR、CRP、D-二聚体、IgA、KL-6、IL-33)诊断RA-ILD的曲线下面积(AUC)分别为0.678、0.667、0.716、0.702、0.666、0.773和0.705。KL-6、IL-33联合检测诊断RA-ILD的AUC为0.816,均优于各项单独检测。结论联合检测RA患者血清KL-6和IL-33,对RA-ILD的早期诊断及病情严重性判断有较高的参考价值。
Objective To understand the expression levels of serum Krebs von den Lungen-6(KL-6)and interleukin 33(IL-33)in patients with rheumatoid arthritis(RA),and to investigate the diagnostic value of detecting serum KL-6 and IL-33 in RA-associated interstitial lung disease(RA-ILD).Methods A total of 88 patients diagnosed with RA who were admitted to the Rheumatology Department of the First Affiliated Hospital of Bengbu Medical College and the First Affiliated Hospital of Anhui Hospital of Science and Technology from May 2022 to February 2023 were selected.They were divided into general RA group(40 cases)and RA-ILD group(48 cases)according to the presence of interstitial lung disease(ILD)on lung CT.Serological indicators of RA,such as serum rheumatoidfactors(RF),erythrocytesedimentationrate(ESR)and anticyclic citrullinated peptide antibody(anti-CCP)were found in all patients.At the same time,the levels of serum KL-6 and IL-33 in the above patients were determined,the correlation between each index and ILD was analyzed,and the diagnostic efficiency of each index for RA-ILD was analyzed by receiver operating characteristic(ROC)curve.Results Serum KL-6 and IL-33 levels were significantly increased in RA-ILD group;serum KL-6 was positively correlated with ESR,CRP,and D-dimer,and serum IL-33 was positively correlated with IgG and globulin.After ROC analysis,the area under the curve(AUC)of each index for diagnosing RA-ILD was RF(0.678),ESR(0.667),CRP(0.716),D-dimer(0.702),IgA(0.666),KL-6(0.773)and IL-33(0.705).The AUC of combined detection of KL-6 and IL-33 in diagnosing RA-ILD was 0.816,both of which were superior to individual detection.Conclusion The combined detection of serum KL-6 and IL-33 in RA patients has a high reference value for the early diagnosis of RA-ILD and the assessment of disease severity.
