1、医学检验与临床2014年第25卷第4期MedicalLaboratoryScienceandClinics,2014,Vo125,No.4·23·血清降钙素原在呼吸道感染疾病中临床应用价值李念顺王小丽彭琳马国良(山东省莱芜市人民医院检验科,山东莱芜271100)【摘要】目的:探讨血清降钙素原(PCT)在呼吸道感染疾病中的临床应用价值。方法:选取2013年1月~2014年2月呼吸道感染病人108例,健康体检人员50例,根据病原学检查及临床表现将入选病例分为细菌感染组57例、非细菌病原体感染组51例及
2、正常对照组50例,分别进行血清降钙素原(PCT)、C反应蛋白(CRP)及外周血白细胞计数(WBC)水平测定与比较,全部病例于治疗前、使用抗菌药物3d、6d及出院前测定血清PCT、CRP、WBC水平并分析比较。结果:治疗前PCT水平在细菌感染组显著升高,为(4.89±1.25)ng/ml、在非细菌病原体感染组轻度升高,为(0.52±0.32)ng/ml、在正常对照组极低,为(0.06±0.04)ng/ml,两两比较差异有统计学意义(P3、显高于非细菌病原体感染组,有统计学差异(P<0.05);动态监测细菌感染组发现,抗茵药物治疗后血清PCT可快速下降,由(4.89±1.25)ng/ml降至(2.34±2.08)ng/ml,而CRP、WBC在细菌感染被控制后仍维持在高水平,分别为(32.06±11.35)~(25.72±9.57)ng/ml、(11.5±6.7)~(9.2±5.1)×10/L,其回落速度慢于血清PCT;诊断呼吸道细菌感染,以PCT>0.5ng/ml为界,其敏感性为92.6%、特异性为93.8%,以CRP>8mg/L为4、界,其敏感性为87.4%、特异性为50.0%,以WBC>10×10/L为界,敏感性为60.2%、特异性为61.3%。结论:血清PCT检测可作为呼吸道细菌感染早期诊断指标,对细菌感染诊断具有良好的敏感性和特异性;动态监测PCT水平能反映呼吸道细菌感染的严重程度及抗菌药物的疗效,为临床医师及时调整抗茵药与评估病情转归提供客观依据。[关键词】降钙素原;细菌感染:c反应蛋白;白细胞计数Clinicalapplicationvalueofserumprocalcitonininrespiratorytrac5、tinfectiondiseaseLINian—Shun,WANGXiao—Li,PENGLin,etal(DepartmentofClinicalLaboratory,People’sHospitalofLaiwuCityinShandongProvince,Laiwu,Shandong271100,China)[Abstract]0bjective:Toinvestigatetheclinica1applicationvalueoftheserumprocalcitonin(PcT)inres6、piratorytractinfection.Methods:Atotalof108hospitalizedpatientswithrespiratorytractinfectionsfromJanuary2013toFebruary2014and50healthypersonsafterphysicalcheckwereselectedinstudy.Allpatientsweredeterminedthe1evelofserumPCT.C-reactiveprotein(CRP)andwhit7、ebloodcellcount(WBC)beforetreatment,aftertheuseofantibioticsfor3days,6daysandbeforedischarge.Results:Inpre-antibiotictreatmentserumPCTsignificantlyincreasedinthebacterialinfectiongroupf4.89±1.25)ng/ml,mildlyincreaseinthenon-bacterialinfectiongroupf0.58、2±0.32)ng/mlanddid’tincreaseinhealthycontrolgroupf0.06±0.04)ng/m1.Thedifierencewasstatisticallysignificantwitheachothergroupfp<0.011.WhiletheCRPandWBCaresignificantlyincreasedinthebacterialinfectiousgroupandnon-bacterialinfectiongroup.Thereexi
