目的对血清降钙素原(PCT)的检测在儿科感染性疾病中的应用价值进行研究。方法 75例疑似感染患儿作为研究对象,根据出院诊断标准将其分为细菌感染组30例、病毒感染组25例以及非感染组20例,并根据感染程度将细菌感染组分为重症感染组12例与局部感染组18例。检测各组血清PCT、全血细胞计数(CBC)及C-反应蛋白(CRP)水平。结果细菌感染组患儿的血清PCT、CBC及CRP水平均明显高于病毒感染组和非感染组(P<0.05);重症感染组的血清PCT水平明显高于局部感染组(P<0.05);细菌感染组中,PCT阳性检出率显著高于CRP阳性检出率(P<0.05)。结论可将血清PCT水平作为诊断儿科细菌感染与判别感染严重程度的重要指标,临床应用价值较高。
Objective To investigate the value of serum procalcitonin (PCT) detection in pediatric infectious diseases. Methods Seventy-five children with suspected infection were divided into bacterial infection group (n = 30), virus infection group (n = 25) and non-infected group (n = 20) according to the diagnostic criteria of discharge. According to the degree of infection, the bacterial infection was divided into severe infection group 12 cases and 18 cases of local infection group. The levels of serum PCT, CBC and CRP in each group were detected. Results The levels of serum PCT, CBC and CRP in bacterial infection group were significantly higher than those in viral infection group and non - infected group (P <0.05). The serum PCT level in severe infection group was significantly higher than that in local infection group (P <0.05). Among the bacterial infection groups, the positive rate of PCT was significantly higher than that of CRP (P <0.05). Conclusion Serum PCT levels can be used as an important index in diagnosis of pediatric bacterial infection and discrimination of infection severity, with high clinical value.
