[摘要]目的 探讨早期类风湿关节炎患者予以ROC曲线评价Logistic回归联合指标的应用价值。方法 选取2017年9月~2018年8月我院收治的136例类风湿关节炎患者及38例同期健康体检者,检测其抗环瓜氨酸肽抗体(CCP)、C反应蛋白(CRP)、类风湿因子(RF)、红细胞沉降率(ESR),绘制ROC曲线并计算曲线下面积(AUC),把4个指标通过Logistic回归模型建立A组(CCP+RF)、B组(CCP+RF+CRP)、C组(CCP+RF+CRP+ESR),并分别进行比较。结果 C组具有最大的AUC(P<0.05),A、B、C组的AUC分别为0.887、0.892、0.916;B组的特异性(94.96%)高于A组(91.77%)与C组(93.72%)(P<0.05);C组的灵敏度(86.54%)高于A组(79.54%)与B组(82.28%),差异有统计学意义(P<0.05)。结论 通過ROC曲线评价Logistic回归模型得出,4项指标联合检测能够提高早期类风湿关节炎的诊断效能,为临床对类风湿关节早发现早治疗提供重要依据。

[Abstract] Objective To investigate the application value of receiver operating characteristic (ROC) curve evaluation in Logistic regression models in early rheumatoid arthritis patients. Methods A total of 136 patients with rheumatoid arthritis and 38 healthy subjects who were admitted to our hospital from September 2017 to August 2018 were enrolled in this study. The anti-cyclic citrullinated peptide antibody (CCP) and C-reactive protein (CRP), rheumatoid factor (RF), and erythrocyte sedimentation rate (ESR) were detected and ROC was plotted and area under ROC curve (AUC) was calculated. Using logistic regression, three groups were established based on the above-mentioned four indicators: group A (CCP+RF) and group B (CCP+RF+CRP), and group C (CCP+RF+CRP+ESR), and each of which was compared. Results The largest AUC in the group C, followed by group B, and group A in 0.916, 0.892, and 0.887 accordingly (P<0.05). The specificity of group B was 94.96%, higher than that of group A (91.77%) and group C (93.72%) (P<0.05). The sensitivity of group C was 86.54%, higher than that of group A (79.54%) and group B (82.28%), with statistical differences (P<0.05). Conclusion The ROC curve evaluation on Logistic regression model shows that the joint detection of the four indicators can improve the diagnostic efficiency of early rheumatoid arthritis, and provide an important basis for clinical early detection of rheumatoid joints.

类风湿关节炎作为临床上较为常见的自身免疫性疾病,患者在临床上的主要特征为滑膜炎,患者通常从小关节症状逐渐累及大关节,病情严重者甚至会出现僵硬变形状况,影响患者的生活质量与身心健康[1]。现阶段,关于类风湿关节炎预防的最佳方式便是及早发现与治疗,但由于大部分患者在疾病早期并无典型症状,且临床症状复杂多样,难以通过临床症状进行准确判断,进而对该病的诊断造成了阻碍。目前最常用的检查手段为类风湿因子(RF)的检测及X线检查,但是一般患者出现骨关节破坏才被检出,而RF缺乏特异性,不利于早期诊断及治疗。本研究对136例类风湿关节炎患者及38例健康体检者的抗环氨酸肽抗体(CCP)、C反应蛋白(CRP)、类风湿因子(RF)、红细胞沉降率(ESR)指标进行检测,并建立Logistic回归模型,采用ROC曲线评价其临床应用价值,现报道如下。
