摘要: 目的 评价血清抗环瓜氨酸肽抗体 (anti-CCP)、 类风湿因子 (RF) 及14-3-3η蛋白联合检测对类风湿关节炎 (RA) 的诊断价值。方法 选取RA患者94例作为RA组, 年龄、 性别相匹配的疾病对照组和健康对照组各40例。采用酶联免疫吸附试验检测所有受试者的血清14-3-3η和anti-CCP, 散射免疫比浊法检测RF水平。将以上3个指标分别进行串联和并联试验, 采用敏感度、 特异度、 阳性预测值、 阴性预测值、 准确度及约登指数 (YI) 分析各试验方案对RA的诊断效能。结果 在anti-CCP、 RF及14-3-3η蛋白3个指标中, anti-CCP的准确度 (87.4%)、 YI (0.753) 最高, 同时敏感度 (84.0%) 也最高, 是最好的RA诊断指标; 双项目检测方案中, anti-CCP与RF并联的准确度 (87.4%) 和 YI (0.742) 最高, 同时敏感度 (90.4%) 也较高, 是较为理想的组合; 三项目检测方案中,[(14-3-3η+anti-CCP) /RF]、[(14-3-3η+RF) /anti-CCP]、[(14-3-3η/RF) +anti-CCP] 和 [(14-3-3η+anti-CCP) / (14-3-3η+RF) / (anti-CCP+RF)] 的准确度 (87.4%、 87.9%、 87.4%、 87.9%) 及YI (0.745、 0.756、 0.757、 0.760) 在联合检测方案中较高, 而 [(14-3-3η+anti- CCP) /RF]、[(14-3-3η+RF) /anti-CCP] 和 [(14-3-3η+anti-CCP) / (14-3-3η+RF) / (anti-CCP+RF)] 的敏感度 (88.3%、 89.4%、 87.2%) 较 [(14-3-3η/RF) +anti-CCP] 的敏感度 (81.9%) 高, 是较为理想的组合。结论 在anti-CCP、 RF及14- 3-3η蛋白3个指标中, anti-CCP准确度、 YI和敏感度最高。联合检测方案 [(14-3-3η+ anti-CCP) /RF]、[(14-3-3η+ RF) /anti-CCP]、[(14-3-3η+anti-CCP) / (14-3-3η+RF) / (anti-CCP+RF)] 的准确度和YI较高, 兼有较高的敏感度。

Abstract: Objective To evaluate the clinical value of combined detection of serum rheumatoid factor (RF), anti- cyclic citrullinated peptide antibody (anti-CCP)and 14-3-3η protein in the diagnosis of rheumatoid arthritis (RA). Methods A total of 94 RA patients were selected as RA group, and 40 healthy people with age, sex matched were used as control group. Serum 14-3-3η protein and anti-CCP were analyzed by enzyme linked immunosorbent assay (ELISA). RF levels were measured by scattering immune turbidimetry. Series and parallel tests were carried out respectively with the above 3 indexes. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and Youden’ s index (YI) were used to analyze the diagnostic efficacy of each test for RA. Results Among anti-CCP, RF and 14-3-3η protein, anti-CCP showed the highest accuracy (87.4%), YI (0.753) and the highest sensitivity (84.0%), therefore, it was the best measure of RA diagnosis. When using two serum makers, anti-CCP together with RF were an ideal combination with the highest accuracy (87.4%), YI (0.742) and the highest sensitivity (90.4%). While using three serum markers, [(14-3-3η + anti-CCP) / RF], [(14-3-3η + RF) / anti-CCP], [(14-3-3η / RF) + anti-CCP] and [(14-3-3η+anti-CCP) / (14-3-3η+ RF) / (anti-CCP + RF)] showed the higher accuracy (87.4%, 87.9%, 87.4%, 87.9%) and YI (0.745, 0.756, 0.757, 0.760). [(14-3- 3η + anti-CCP) / RF], [(14-3-3η + RF) / anti-CCP] and [(14-3-3η+anti-CCP) / (14-3-3η+ RF) / (anti-CCP + RF)] were the higher sensitivity (88.3%, 89.4%, 87.2%) than [(14-3-3η / RF) + anti-CCP] (81.9%), which was an ideal combination. Conclusion Among anti-CCP, RF and 14-3-3η protein, anti-CCP has the highest accuracy, YI has the highest sensitivity. The combination detection [(14-3-3η + anti-CCP) / RF], [(14-3-3η + RF) / anti-CCP] and [(14-3-3η+anti- CCP) / (14-3-3η+ RF) / (anti-CCP + RF)] has higher accuracy and higher YI, along with good sensitivity.
