血清降钙素原在儿童发热性疾病中的应用价值分析(1)
摘 要:目的 探讨降钙素原对儿童发热性疾病早期诊断及鉴别诊断的应用价值。方法 选取2015年7月~2016年3月我院收治的发热患儿270例,其中细菌感染组80例,非细菌感染组130例,对照组(非发热性疾病患儿)60例,入院前1 d已全部行WBC+CRP检测,入院当天全部行PCT检测,对比三组检测结果。结果 细菌感染组外周血WBC+CRP水平高于对照组,差异有统计学意义(P<0.05)。细菌感染组PCT水平均高于非细菌感染组及对照组,差异均有统计学意义(P<0.05)。结论 血清PCT可作为早期诊断细菌感染的可靠指标,对儿童发热性疾病的鉴别诊断及抗生素的使用具有重要意义。

Abstract:Objective To evaluate the value of procalcitonin(PCT)in early diagnosis and differential diagnosis of febrile diseases in children.Methods 270 children with fever were selected from July 2015 to March 2016 in our hospital.There were 80 cases of bacterial infection group,130 cases of non-bacterial infection group and 60 cases of control group(non-febrile disease).All of them were examined by WBC+CRP 1 d before admission.On the day of admission,all patients were examined with PCT,and the results of three groups were compared.Results The level of WBC+CRP in the peripheral blood of the bacterial infection group was higher than that of the control group,and the difference was statistically significant(P<0.05).The level of PCT in the bacterial infection group was higher than that of the non bacterial infection group and the control group,and the difference was statistically significant(P<0.05).Conclusion Serum PCT can be used as a reliable index for early diagnosis of bacterial infection,and it is of great significance in the differential diagnosis of febrile diseases in children and the use of antibiotics.

發热性疾病是儿童常见病,病因主要包括感染性和非感染性两大类,其中以感染性发热最常见。多数发热是由细菌、病毒、真菌或免疫因素所引起,尽早明确病因对患病儿童早期治疗及预后有重要的意义。常用的炎性指标包括外周血白细胞(WBC)、C-反应蛋白(CRP)及PCT。其中,WBC和CRP在儿童感染性疾病中广泛应用,两者的敏感性和特异性不高,对病毒感染与细菌感染或支(衣)原体感染、感染与非感染疾病等病原微生物感染的早期鉴别价值不高。而血清降钙素原(PCT)作为甲状腺C细胞分泌一种无激素活性的糖蛋白(降钙素的前体物),是一种敏感性、特异性均较高的感染相关性生物指标,且稳定性好[1]。自1993年Assicot等发现细菌感染的患者PCT水平明显增高以后,PCT在感染性疾病的早期诊断与鉴别诊断中的意义得到了充分肯定。本研究针对270例不同病因发热患儿,均进行WBC+CRP和降钙素原(PCT)的检测,探讨儿童发热性疾病中,降钙素原对疾病早期诊断和鉴别诊断中的意义,以及动态监测其对抗菌药物治疗的效果评估。

1资料与方法
1.1一般资料 选取2015年7月~2016年3月本科收治的患儿270例,所有程序通过医院伦理委员会批准。依据是否感染细菌将患儿分为细菌感染组80例、非细菌感染组130例、对照组(非发热性疾病组)60例。细菌感染组中,男43例,女37例;年龄2~11岁,平均年龄(4.98±0.45)岁;包括细菌性肺炎42例,急性化脓性扁桃体炎23例,细菌性肠炎9例,败血症6例。非细菌感染组中,男70例,女60例;年龄1~13岁,平均年龄(5.01±0.50)岁;包括急性细支气管炎67例,支原体感染39例,川崎病24例。对照组中,男34例,女26例;年龄1~14岁,平均年龄(5.11±0.62)岁;包括血小板减少性紫癜16例,营养性贫血17例,过敏性紫癜27例。三组患者的一般资料相比,差异无统计学意义(P>0.05),有可比性。
1.2方法 所有患儿在入院前1 d行外周血WBC+CRP检测,入院当天采静脉血2 ml用于PCT检测。PCT测定采用化学发光法,为定量指标。健康儿童血清PCT正常值为0~0.05 ng/ml,外周血WBC正常值为(4.00~10.00)×109/L,CRP正常值<5.0 mg/L。, 百拇医药(李娟 田鹏 刘琦)
