Behcet's disease (BD) is a vasculitis. Lines of evidence suggest miRNAs as diagnostic and prognostic markers in autoimmune diseases. This study was designed to investigate the potential role of miR-21, miR-146b and miR-326 as biomarkers for diagnosis, predicting organs involvement and measuring BD activity. In this cross-sectional study, the study groups consisted of 46 BD patients and 70 age- and sex-matched healthy volunteers. The expression rates of three miRNAs were determined by quantitative real-time PCR. Our results demonstrated significantly lower expression of miR-21 and miR-146b and higher expression of miR-326 in BD patients. MiR-21 expression rate in patients with severe eye involvement and miR-326 expression rate in patients with uveitis and severe eye involvement were increased. MiR-326 expression rate can be used as a biomarker for prediction of uveitis and severe eye involvement in patients with BD.
贝赫切特病（BD）是一种血管炎。有证据表明，miRNA 可作为自身免疫性疾病的诊断和预后标志物。本研究旨在探讨 miR-21、miR-146b 和 miR-326 作为诊断、预测器官受累和衡量 BD 活动的生物标志物的潜在作用。在这项横断面研究中，研究组包括 46 名 BD 患者和 70 名年龄和性别匹配的健康志愿者。通过定量实时 PCR 测定了三种 miRNA 的表达率。我们的研究结果表明，BD 患者的 miR-21 和 miR-146b 表达水平显著降低，miR-326 表达水平升高。严重眼部受累患者的 miR-21 表达率和葡萄膜炎及严重眼部受累患者的 miR-326 表达率增加。miR-326 表达率可作为预测 BD 患者葡萄膜炎和严重眼部受累的生物标志物。
