探讨铁蛋白和C反应蛋白(CRP)对成年型斯蒂尔病(AOSD)患者巨噬细胞活化综合征(MAS)发生及死亡率的预测作用。
方法
方法:采用logistic回归分析评价诊断时血清铁蛋白和CRP水平对MAS发生和死亡率的预测作用,并建立ROC曲线分别识别MAS高危患者和死亡率。
结果
结果:在147例AOSD患者中,铁蛋白水平可预测MAS (OR: 1.971;P: 0.002;Ci 95%: 1.280-3.035),最佳临界值为1225ng/ml(灵敏度88%;特异性57%)。CRP水平可预测这些患者的死亡率(OR: 2.155;P: 0.007;Ci 95%: 1.228-3.783),最佳临界值为68.7 mg/L(敏感性80%;特异性为65%)。
结论
结论:铁蛋白和CRP在AOSD患者大队列中分别对MAS和死亡率的预测作用,确定了预后不良风险较高的亚群。考虑到CRP和铁蛋白的分析广泛可用,这些结果可以很容易地转移到临床实践中,从而改善AOSD患者的管理。

Abstract
Ferritinand C-reactive protein are predictive biomarkers of mortality and macrophage activation syndrome in adult onset Still's disease. Analysis of the multicentre Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale (GIRRCS) cohort.
Objective
Objective:To assess the predictive role of ferritin and C-reactive protein (CRP) on occurrence of macrophage activation syndrome (MAS) and mortality in patients with adult onset Still's disease (AOSD), a rare and severe disease, included in the multicentre Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale (GIRRCS) cohort.
Methods
Methods:The predictive role, at the time of diagnosis, of serum levels of ferritin and CRP on occurrence of MAS and mortality, was evaluated by logistic regression analyses and receiveroperating characteristic (ROC) curves were built to identify patients at high risk of MAS and mortality, respectively.
Results
Results:In assessed 147 patients with AOSD, levels of ferritin were predictive of MAS (OR: 1.971; P: 0.002; CI 95%:1.2803.035). The ROC curve showed that the best cut off for ferritin was 1225 ng/ml in predicting MAS (sensitivity 88%; specificity 57%). Levels of CRP were predictive of mortality in these patients (OR: 2.155; P: 0.007; CI 95%: 1.228-3.783). The ROC curve showed that the bestcutoff for CRP was 68.7 mg/L in predicting mortality (sensitivity 80%; specificity of 65%).
Conclusions
Conclusions:We reported the predictive role of ferritin and CRP on MAS and mortality, respectively, in a large cohort of patients with AOSD, identifying subsets at higher risk of poor prognosis. Considering that the analysis of CRP and ferritin is widely available, these results could be readily transferable into clinical practice, thus improving the management of patients with AOSD.
