新生儿感染诊断中降钙素原及超敏C-反应蛋白检测的临床意义

摘要

目的 探讨采用超敏C-反应蛋白(hs-CRP)和降钙素原(PCT)作为检测指标在新生儿感染诊断中的临床价值.方法 选取本院新生儿科2014年9月至2016年10月期间所收治新生儿60例作为观察对象,所有患儿均经诊断确诊为感染性疾病,将其作为观察组,另选取同期本院体检健康新生儿60例作为对照组,对两组新生儿进行血清降钙素原、超敏C反应蛋白检测,其中超敏C反应蛋白行散射比浊法检测,降钙素原行双抗体夹心精标法检测,对两组新生儿相关指标检测结果进行对比分析.结果 观察组新生儿其白细胞计数、hs-CRP水平、PCT水平均明显高于对照组,差异具有统计学意义(P＜0.05);同PCT相比,hs-CRP对于新生儿感染性疾病的诊断灵敏度、特异性均处于较低水平;同单一指标检测相比,PCT联合hs-CPR检测对于新生儿感染性疾病的诊断灵敏度、特异性均处于较高水平.结论 在新生儿感染性疾病中,血清超敏C-反应蛋白、降钙素原均存在显著的特异性变化,可作为感染性疾病的鉴别、诊断指标,其中降钙素原对于新生儿感染性疾病的诊断灵敏度、特异性优于超敏C-反应蛋白,采用二者进行联合检测可有效提高对于此类患儿的临床诊断价值.%Objective To evaluate high sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) as the detection index in the diagnosis of neonatal infection.Methods Sixty newborn infants were enrolled in the Department of Neonatology from September 2014 to October 2016.All the children were diagnosed as infectious diseases and treated as observation group.60 cases of neonatal healthy neonates were taken as the control group.Serum neonates were tested for PCT and Hs-CRP.Hs-CRP was detected by turbidimetric assay.Standard test and the two groups of neonatal related indicators test results were compared and analyzed.Results The white blood cell count,hs-CRP level and PCT level of the neonates in the observation group were significantly higher than those in the control group,and the difference was significant (P ＜ 0.05).Compared with the PCT,hs-CRP for neonatal infectious diseases in the diagnosis of sensitivity and specificity were at a low level;compared with a single index test,PCT joint hs-CPR detection of neonatal infectious disease diagnostic sensitivity andspecificity were at a high level.Conclusion In neonatal infectious diseases,serum allergy-sensitive C-reactive protein and procalcitoninhave significant specific changes,and can be used as identification of infectious diseases anddiagnostic indicators.Calcitonin is betterfor neonatal infectious diseases of the diagnostic sensitivity and specificity than the high-sensitivity C-reactive protein.The combination of the two can be used to effectively improve the clinical diagnosis of such children.
