降钙素原与血流感染相关性

The Association of Procalcitonin and Bloodstream Infectious

目的:探讨降钙素原(PCT)检测在血液感染性疾病中的诊断价值。方法:选择2014年5月-2015年5月笔者所在医院同时检测PCT和血培养的患者377例,分析比较其检测结果。结果:血培养阳性患者PCT送检率27.45%;血培养阳性组的PCT阳性率41.4%,高于血培养阴性组的11.7%,差异有统计学意义(P<0.05);血培养鉴定出革兰阴性菌的患者PCT中位数15.54 ng/ml,明显高于革兰阳性菌患者的0.14 ng/ml,差异有统计学意义(P<0.05).结论:血清PCT检测有助于细菌性血流感染的诊断,其检测方法简便、可靠,值得临床推广应用。

Objective： To explore the application value of procalcitonin（PCT） in blood infectious disease.Method： 377 patients who received the examination of PCT and blood culture in our hospital from May 2014 to May 2015 were selected.The testing results were analyzed.Result： PCT examination rate in the positive blood culture was 27.45%.The PCT positive rate of the positive blood culture group was 41.4%, higher than 11.7% of the negative blood culture group, the difference was statistically signifieant（P〈0.05）.The median level of serum PCT was 15.54 ng/ml in gram-negative bacteria, higher than 0.14 ng/ml in gram-positivebacteria, the difference was statistically significant（P〈0.05）.Conclusion： Serum PCT can help the diagnosis of bacterial bloodstream infeetions, its detection method is simple and reliable, which is worthy of clinical popularization and application.
