摘要

背景:类风湿性关节炎(RA)和骨关节炎(OA)的完整循环长非编码RNA(lncRNA)特征仍未被发现。lncRNA整合素亚单位β2(ITGB2)-反义RNA 1(ITGB2-AS1)会影响ITGB2的表达;然而,关于它在RA和OA中的表达和临床用途的知识还存在空白。本研究调查了血清 ITGB2-AS1作为新型诊断生物标记物的潜力,以及它与 ITGB2 表达及其配体细胞间粘附分子-1(ICAM-1)、疾病活动性和 RA 及原发性膝关节 OA 患者严重程度的相关性:43名RA患者、35名膝关节OA患者和22名健康志愿者:与健康对照组相比,RA 患者血清中 ITGB2-AS1 表达上调,而膝关节 OA 患者血清中 ICAM-1 蛋白水平无明显变化。在接受者操作特征分析中,ITGB2-AS1显示出对RA与对照组的鉴别潜力(AUC = 0.772),而ICAM-1显示出对RA和膝关节OA与对照组的诊断潜力(AUC分别为0.804和0.914)。在多变量分析中,血清 ITGB2-AS1 和 ICAM-1 与罹患 RA 的风险有关,而只有 ICAM-1 与罹患膝关节 OA 的风险有关。结合 ITGB2-AS1 和 ICAM-1 的面板显示出对 RA 有很强的诊断能力(AUC = 0.9,灵敏度 = 86.05%,特异性 = 91.67%)。有趣的是,血清 ITGB2-AS1 与 RA 患者的疾病活动度(DAS28)以及这两种疾病的 ITGB2 mRNA 表达呈正相关,而 ICAM-1 与膝关节 OA 患者的 ITGB2 表达呈正相关:我们的研究表明,血清 ITGB2-AS1是一种新的潜在的 RA 诊断生物标记物,与疾病活动性相关。结合 ITGB2-AS1 和 ICAM-1 的预测面板可能在 RA 诊断中具有临床实用性。我们还重点研究了 ICAM-1 与膝关节 OA 诊断的相关性。在这两种疾病中,血清 ITGB2-AS1 与 ITGB2 表达的相关性可能对进一步的机理研究具有启发意义。

Serum lncRNA ITGB2-AS1 and ICAM-1 as novel biomarkers for rheumatoid arthritis and osteoarthritis diagnosis.

Background: The complete circulating long non-coding RNAs (lncRNAs) signature of rheumatoid arthritis (RA) and osteoarthritis (OA) is still uncovered. The lncRNA integrin subunit beta 2 (ITGB2)-anti-sense RNA 1 (ITGB2-AS1) affects ITGB2 expression; however, there is a gap in knowledge regarding its expression and clinical usefulness in RA and OA. This study investigated the potential of serum ITGB2-AS1 as a novel diagnostic biomarker and its correlation with ITGB2 expression and its ligand intercellular adhesion molecule-1 (ICAM-1), disease activity, and severity in RA and primary knee OA patients.

Subjects: Forty-three RA patients, 35 knee OA patients, and 22 healthy volunteers were included.

Results: Compared with healthy controls, serum ITGB2-AS1 expression was upregulated in RA patients but wasn't significantly altered in knee OA patients, whereas serum ICAM-1 protein levels were elevated in both diseases. ITGB2-AS1 showed discriminative potential for RA versus controls (AUC = 0.772), while ICAM-1 displayed diagnostic potential for both RA and knee OA versus controls (AUC = 0.804, 0.914, respectively) in receiver-operating characteristic analysis. In the multivariate analysis, serum ITGB2-AS1 and ICAM-1 were associated with the risk of developing RA, while only ICAM-1 was associated with the risk of developing knee OA. A panel combining ITGB2-AS1 and ICAM-1 showed profound diagnostic power for RA (AUC = 0.9, sensitivity = 86.05%, and specificity = 91.67%). Interestingly, serum ITGB2-AS1 positively correlated with disease activity (DAS28) in RA patients and with ITGB2 mRNA expression in both diseases, while ICAM-1 positively correlated with ITGB2 expression in knee OA patients.

Conclusion: Our study portrays serum ITGB2-AS1 as a novel potential diagnostic biomarker of RA that correlates with disease activity. A predictive panel combining ITGB2-AS1 and ICAM-1 could have clinical utility in RA diagnosis. We also spotlight the association of ICAM-1 with knee OA diagnosis. The correlation of serum ITGB2-AS1 with ITGB2 expression in both diseases may be insightful for further mechanistic studies.
