摘　　要：目的:探讨降钙素原(procalcitonin,PCT)、网织血小板百分数(reticulated platelet percent,RP%)、C反应蛋白(C reactive protein,CRP)在白血病合并肺部感染预后评估中的价值。方法:选取2010年1月-2019年12月于本院就诊的白血病合并肺部感染患儿60例作为研究组,另选取同期于本院进行健康体检的健康儿童50例作为对照组。以入院当日为起点,入院3个月或患儿死亡为终点,将研究组患儿分为存活组23例和死亡组37例。所有患儿均进行对症支持和抗生素治疗,检测并比较各组血清PCT、RP%、CRP水平。结果:研究组PCT、RP%、CRP水平均显著高于对照组,差异均有统计学意义(P<0.05)。第1、5、9天,死亡组PCT、RP%、CRP水平均显著高于存活组,差异均有统计学意义(P<0.05)。死亡组PCT、RP%、CRP水平随着时间的延长而逐渐升高,存活组PCT、RP%、CRP水平在第5天达到高峰,而后其水平开始下降,差异均有统计学意义(P<0.05)。PCT、RP%、CRP联合检测的敏感度、AUC均高于单一指标检测。结论:联合检测PCT、RP%、CRP水平对白血病合并肺部感染患儿预后评估具有较好的临床应用价值。Objective:To investigate the prognostic value of procalcitonin(PCT),reticulated platelet percent(RP%)and C reactive protein(CRP)in patients with leukemia complicated with pulmonary infection.Method:A total of 60 children with leukemia complicated with pulmonary infection in our hospital from January 2010 to December 2019 were selected as the study group,and 50 healthy children who received physical examination in our hospital during the same period were selected as the control group.The children in the study group were divided into the survival group(n=23)and the death group(n=37),starting from the day of admission and ending at 3 months after admission or death.All children received symptomatic support and antibiotic treatment.Serum PCT,RP%and CRP levels in each group were detected and compared.Result:The levels of PCT,RP%and CRP in the study group were significantly higher than those in the control group,with statistical significance(P<0.05).On day 1,5 and 9,the levels of PCT,RP%and CRP in the death group were significantly higher than those in the survival group,with statistical significance(P<0.05).The levels of PCT,RP%and CRP in the death group increased gradually with the extension of time,while the levels of PCT,RP%and CRP in the survival group reached the peak on the 5th day and then began to decline,with statistical significance(P<0.05).The sensitivity,AUC of combined detection of PCT,RP%and CRP were higher than those of single index detection.Conclusion:Combined detection of PCT,RP%and CRP levels has good clinical application value in prognosis assessment of children with leukemia complicated with pulmonary infection.
