摘要:

目的 探讨纤维蛋白原/白蛋白比值(FAR)在系统性红斑狼疮(SLE)疾病活动度和狼疮性肾炎(LN)诊断中的价值。方法 选取2023年1—12月上海交通大学医学院附属瑞金医院SLE患者99例(SLE组)和健康体检者50名(正常对照组)。根据有无肾脏受累将SLE患者分为LN组(40例)和无LN组(59例)。检测所有研究对象红细胞沉降率(ESR)、肌酐(Cr)、血尿素氮(BUN)、纤维蛋白原(Fib)、白蛋白(Alb),计算FAR。采用系统性红斑狼疮疾病活动度指数2000(SLEDAI-2000)评分评估SLE患者的疾病活动度。采用Pearson相关分析或Spearman相关分析评估FAR与其他指标的相关性。采用Logistic回归分析评估LN发生的影响因素。采用受试者工作特征(ROC)曲线评价FAR诊断SLE、SLE中重度活动度、LN的效能。结果 SLE组FAR显著高于正常对照组(P<0.001)。LN组FAR显著高于无LN组和正常对照组(P<0.001),其他指标LN组、无LN组和正常对照组之间差异均无统计学意义(P>0.05)。FAR与ESR、Cr、BUN、Fib和SLEDAI-2000评分呈正相关(r值分别为0.459、0.249、0.223、0.806、0.450,P<0.05),与Alb呈负相关(r=-0.604,P<0.05)。FAR是SLE患者发生LN的危险因素[比值比(OR)=1.013,95%可信区间(CI)为1.002~1.024]。对LN患者进行四分位分组,调整混杂因素(年龄、性别、ESR、Cr、BUN、CRP、Fib、Alb)后,Q3组(83.33 mg·g-1<FAR≤110.71 mg·g-1)发生LN的风险是Q1组(FAR≤64.10 mg·g-1)的2.633倍(OR=2.633,95%CI为1.180~5.878)。FAR诊断SLE的曲线下面积(AUC)为0.723 8,判断SLE中重度活动度的AUC为0.748 3,诊断LN的AUC为0.633 9。结论 FAR在SLE疾病活动度评估和LN诊断中均有一定的价值。

Abstract:

Objective To investigate the role of fibrinogen/albumin ratio(FAR)in disease activity and diagnosis of systemic lupus erythematosus(SLE)and lupus nephritis(LN). Methods A total of 99 SLE patients(SLE group)and 50 healthy subjects(healthy control group) from Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January to December 2023 were enrolled. SLE patients were classified into LN group(40 cases)and non-LN group(59 cases). The erythrocyte sedimentation rate(ESR),creatinine(Cr),blood urea nitrogen(BUN),fibrinogen(Fib)and albumin(Alb)were determined,and the FAR was calculated. The disease activity of SLE patients was evaluated using the systemic lupus erythematosus disease activity index 2000(SLEDAI-2000). Pearson correlation analysis or Spearman correlation analysis was used to evaluate the correlation between FAR and other indicators. Logistic regression analysis was used to evaluate the influencing factors of LN occurrence. Receiver operating characteristic(ROC)curve was used to evaluate the efficacy of FAR in diagnosing SLE,SLE moderate-severe activity and LN. Results The FAR in SLE group was higher than that in healthy control group (P<0.001). The FAR in LN group was higher than those in non-LN group and healthy control group (P<0.001),while there was no statistical significance in the other indicators among LN group,non-LN group and healthy control group (P>0.05). FAR was positively correlated with ESR,Cr,BUN,Fib and SLEDAI-2000 score (r values were 0.459,0.249,0.223,0.806 and 0.450,respectively,P<0.05),and it was negatively correlated with Alb (r=-0.604,P<0.05). FAR was a risk factor for LN occurrence in SLE patients [odds ratio (OR)=1.013,95% confidence interval (CI) 1.002-1.024]. After adjusting for confounding factors (age,gender,ESR,Cr,BUN,CRP,Fib,Alb),the risk of LN in the Q3 group (83.33 mg·g-1< FAR≤110.71 mg·g-1) was 2.633 times than that of the Q1 group (FAR≤64.10 mg·g-1) (OR=2.633,95% CI 1.180-5.878). The area under curve(AUC)of FAR for diagnosing SLE was 0.723 8,that for diagnosing moderate-severe SLE activity was 0.748 3,and that for diagnosing LN was 0.633 9. Conclusions FAR has certain value in the assessment of SLE disease activity and the diagnosis of LN.
