Clin Chem Lab Med:降钙素原对上呼吸道感染患者抗生素使用及临床转归的影响

2017-07-02 MedSci MedSci原创

目前已有项试验发现降钙素原(PCT)有助于指导下呼吸道感染和脓毒症患者的抗生素治疗方案。本篇meta分析旨在于分析PCT是否对指导上呼吸道感染(URTI)患者的抗生素治疗方案有利。

目前已有项试验发现降钙素原(PCT)有助于指导下呼吸道感染和脓毒症患者的抗生素治疗方案。本篇meta分析旨在于分析PCT是否对指导上呼吸道感染(URTI)患者的抗生素治疗方案有利。

使用PubMed(MEDLINE)和Cochrane对2016年9月前发表的相关研究文献进行检索。我们对临床诊断为上呼吸道感染成年患者的个体数据进行重新分析,以PRISMA-IPD作为指标对两组数据进行分析。主要可分析的结果为(1)治疗失败:死亡、住院、严重并发症、感染复发或恶化、持续使用抗生素大于28天;(2)使用抗生素14天的后细菌活动得到抑制。次要分析目标是开始抗生素治疗的时机和使用抗生素的总天数。

本分析总共包括644例随访了28天的已确诊上呼吸道感染的患者。在治疗失败的分析显示没有显着差异(33.1% vs 34%,OR 1.0,95% CI 0.7-1.4;P=0.896);细菌活性得到抑制的天数【8 vs 8天,OR 0.2(95% CI 0.4-0.9),P=0.465】。然而, PCT指导抗生素治疗组使用抗生素的总共时间(17.8% vs 51%,OR 0.2,95% CI 0.1-0.3;P<0.001)比与处方指导治疗组短2.4天(95% CI 2.9-1.9;P<0.001)。

因此我们可以得出结论:使用PCT指导抗生素治疗方案,与上呼吸道感染患者预后紧密相连,可明显减少使用抗生素总天数。

在生活中想必我们每个人多多少少都服用过抗生素,有些朋友甚至会把抗生素当做“神药”,不管什么病,首先就服用几粒抗生素。但随着医学知识的慢慢普及,有些人对抗生素唯恐避之而不及,不管病的多严重,坚决不用抗生素。这两种极端现象的存在,足以说明大众对抗生素产生了很大误解。抗生素并不是什么“神药”,也并非一点都不能碰,只要我们消除掉平时用药的一些误区,抗生素也能被我们很好的利用。01误区一:感冒就用抗生素病毒
