[摘要]目的 探討早期類風(fēng)濕關(guān)節(jié)炎患者予以ROC曲線評價Logistic回歸聯(lián)合指標(biāo)的應(yīng)用價值。方法 選取2017年9月~2018年8月我院收治的136例類風(fēng)濕關(guān)節(jié)炎患者及38例同期健康體檢者,檢測其抗環(huán)瓜氨酸肽抗體(CCP)、C反應(yīng)蛋白(CRP)、類風(fēng)濕因子(RF)、紅細(xì)胞沉降率(ESR),繪制ROC曲線并計算曲線下面積(AUC),把4個指標(biāo)通過Logistic回歸模型建立A組(CCP+RF)、B組(CCP+RF+CRP)、C組(CCP+RF+CRP+ESR),并分別進行比較。結(jié)果 C組具有最大的AUC(P<0.05),A、B、C組的AUC分別為0.887、0.892、0.916;B組的特異性(94.96%)高于A組(91.77%)與C組(93.72%)(P<0.05);C組的靈敏度(86.54%)高于A組(79.54%)與B組(82.28%),差異有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論 通過ROC曲線評價Logistic回歸模型得出,4項指標(biāo)聯(lián)合檢測能夠提高早期類風(fēng)濕關(guān)節(jié)炎的診斷效能,為臨床對類風(fēng)濕關(guān)節(jié)早發(fā)現(xiàn)早治療提供重要依據(jù)。

[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.

類風(fēng)濕關(guān)節(jié)炎作為臨床上較為常見的自身免疫性疾病,患者在臨床上的主要特征為滑膜炎,患者通常從小關(guān)節(jié)癥狀逐漸累及大關(guān)節(jié),病情嚴(yán)重者甚至?xí)霈F(xiàn)僵硬變形狀況,影響患者的生活質(zhì)量與身心健康[1]?,F(xiàn)階段,關(guān)于類風(fēng)濕關(guān)節(jié)炎預(yù)防的最佳方式便是及早發(fā)現(xiàn)與治療,但由于大部分患者在疾病早期并無典型癥狀,且臨床癥狀復(fù)雜多樣,難以通過臨床癥狀進行準(zhǔn)確判斷,進而對該病的診斷造成了阻礙。目前最常用的檢查手段為類風(fēng)濕因子(RF)的檢測及X線檢查,但是一般患者出現(xiàn)骨關(guān)節(jié)破壞才被檢出,而RF缺乏特異性,不利于早期診斷及治療。本研究對136例類風(fēng)濕關(guān)節(jié)炎患者及38例健康體檢者的抗環(huán)氨酸肽抗體(CCP)、C反應(yīng)蛋白(CRP)、類風(fēng)濕因子(RF)、紅細(xì)胞沉降率(ESR)指標(biāo)進行檢測,并建立Logistic回歸模型,采用ROC曲線評價其臨床應(yīng)用價值,現(xiàn)報道如下。
