J Infect:生物标志物指导的分诊能否降低社区获得性fUTI住院率?

2018年7月,发表在《J Infect》的一项由荷兰和德国学者进行的研究表明,生物标志物指导的分诊能降低社区获得性发热性尿路感染(fUTI)的住院率。

目的:门诊中,口服抗菌药物常能安全治疗fUTI。然而,少数患者会发生并发症,并可能进展为脓毒性休克。因此,在急诊(ED)中,为了指导最合适的分诊和治疗决策,准确评估疾病严重程度就显得至关重要。

方法:假定fUTI的连续患者从荷兰7个EDs中入组。使用受试者工作特征性曲线下面积(AUROC),比较了中间区肾上腺髓质素原(MR-proADM)、降钙素原(PCT)、C反应蛋白(CRP)和临床评分(PRACTICE)等生物标志物在预测fUTI临床重症病程、初始住院和随后再入院方面的能力。

结果:测量了313名患者的生物标志物浓度,其中259人(83%)来自于ED,54人(17%)来自于门诊。门诊患者中,12人(22%)后来住院。MR-proADM对于预测复杂性fUTI具有最高的诊断准确性(AUROC[95% CI]:0.86[0.79~0.92]),其次是PCT(AUROC[95% CI]:0.69[0.58~0.80])。与在家完成治疗者相比,MR-proADM浓度是仅有的在直接住院和需要后来住院的门诊患者中显着升高的生物标志物。MR-proADM临界值为0.80nmol/L的虚拟分诊算法可造成66%的住院率,仅有2%二次住院。

结论:MR-proADM可准确预测fUTI患者的重症病程,并可鉴别出更多的能在门诊中安全管理的患者数量。在ED中进行初始评估需要将资源集中给疾病严重程度最高的患者。
