摘要
目的系统评价CRP对不明原因发热儿童严重细菌感染的诊断价值。方法检索Medline、EMBASE、Cochrane图书馆、维普中文科技期刊数据库、中国知网、万方数据库和中国生物医学文献数据库,纳入CRP对不明原因发热儿童严重细菌感染诊断价值的文献,检索时间均为建库至2012年10月。采用QUADAS量表对纳入文献进行质量评估,使用MetaDisc1.4软件对纳入文献进行异质性检验及Meta分析。结果初检到314篇文献,7篇文献符合纳入标准进入系统评价(n=2179)。6篇为前瞻性研究,1篇为回顾性研究。CRP的最适界值为30~91mg.L-1。严重细菌感染的患病率为1.7%~29.3%。4篇文献采用多变量Logistic回归分析显示,CRP是严重细菌感染独立的预测因素。报道敏感度和特异度文献间具有高度的异质性,采用描述性分析,CRP不同最适界值诊断严重细菌感染的敏感度为33%~89%,特异度为75%~97%。报道阳性似然比和阴性似然比的文献间具中度异质性,采用随机效应模式合并,合并阳性似然比为4.43(95%CI:3.49~5.63),阴性似然比为0.39(95%CI:0.29~0.54)。SROC曲线下面积为0.85,Q指数为0.78。结论在以不明原因发热就诊的婴幼儿中,CRP对严重细菌感染具有中等的诊断价值,应用时尚需结合临床表现及其他实验室检查指标。
