ICU 危重病患者深部真菌感染血清中降钙素原和（1，3）-β-D 葡聚糖联合检测的临床意义

摘要

目的：探讨降钙素原（PCT）和（1，3）-β-D 葡聚糖（G 试验）联合检测在 ICU 危重病患者深部真菌感染诊断中的临床应用价值。方法对2012年11月～2014年8月确诊为深部真菌感染的 ICU 危重病患者106例进行血清 PCT 和（1，3）-β-D 葡聚糖含量检测，并与 ICU 非深部真菌感染的危重患者519例进行对比分析，以配对 t 检验来比较结果之间的差异性。结果106例深部真菌感染的 ICU 危重病患者血清中 PCT 为0.701±0.22 pg／ml 及（1，3）-β-D 葡聚糖为37.82±18.43 pg／ml，明显高于519例 ICU 非深部真菌感染的危重患者血清中的 PCT（0.238±0.12 pg／ml）及（1，3）-β-D 葡聚糖（14.96±4.37 pg／ml），两者结果比较差异有统计学意义（t＝7.426，8.179，P 均＜0.05）；106例深部真菌感染的 ICU 危重病患者血清中 PCT 阳性检出率为57.5％（61／106），明显低于（1，3）-β-D 葡聚糖阳性检出率89.6％（95／106），差异有统计学意义（χ2＝13.645，P ＜0.05）。结论ICU 深部真菌感染危重病患者血清中的 PCT 和（1，3）-β-D 葡聚糖含量明显高于ICU 非深部真菌感染的危重患者，PCT 和（1，3）-β-D 葡聚糖联合检测对 ICU 危重病患者深部真菌感染诊断有重要的临床意义。%Objective To explore the clinical application of jiont detection of critical patients procalcitomin (PCT)and (1,3)-beta D-glucan with deep fungus infection in ICU.Methods From November 2012 to August 2014 diagnosed with deep fun-gal infection of ICU critical patients,106 cases of patients with serum PCT and (1,3)-beta-D glucan content detection,and ICU of deep fungal infection in critically ill patients,519 cases were analyzed,with differencesbetween the paired t test to compare the results.Results 106 patients with deep fungal infection of ICU critical patients serum PCT for 0.701 ±0.22 pg/ml and (1,3)-beta-D glucan for 37.82±18.43 pg/ml,significantly higher than the 519 cases of ICU of deep fungal infec-tion in critically ill patients in the serum PCT for 0.238±0.12 pg/ml and (1,3)-beta-D glucan for 14.96 ±4.37 pg/ml, comparing differences between both results was statistically significant (t=7.426,8.179,P <0.05).106 patients with deep fungal infection of ICU critical patients serum PCT positive detection rate was 57.5% (61/106),significantly lower than the (1,3)-beta-D glucan positive detection rate 89.6% (95/106),difference was statistically significant (χ2 = 13.645,P <0.05).Conclusion Deep fungal infection in critical care patients in the ICU in the serum PCT and (1,3)-beta-D glucan con-tent of deep fungus infection in critically ill patients was significantly higher than the ICU,PCT and (1,3)-beta-D glucan joint detection of deep fungal infection in patients with ICU critical patients diagnosis has important clinical significance.
