[摘要]目的 研究降鈣素(PCT)和C反應(yīng)蛋白(CRP)聯(lián)合檢測在新生兒感染性疾病診斷中的價值。方法 研究對象選取我院2016年3月~2017年4月收治的確診有感染性疾病新生兒44例(觀察組)及正常新生兒44例(對照組),于治療前采集感染性疾病患兒3 ml靜脈血,對照組在出生后7 d內(nèi)采集靜脈血3 ml,檢測兩組PCT、CRP;取觀察組患兒治療前及治療后10 d的靜脈血,檢測PCT、CRP、中性粒細(xì)胞(NEUT)含量,使用Spearman秩相關(guān)系數(shù)檢驗(yàn)PCT、CRP與NEUT含量的相關(guān)性。結(jié)果 兩組PCT、CRP血清濃度比較,觀察組均顯著高于對照組(P<0.05),觀察組PCT及CRP陽性率顯著高于對照組(P<0.05)。治療后,觀察組患兒PCT、CRP與NEUT含量與治療前比較,均顯著降低,差異均有統(tǒng)計(jì)學(xué)意義(P<0.05),PCT、CRP與NEUT兩兩間做基于Spearman秩相關(guān)系數(shù)顯示,PCT、CRP與NEUT兩兩間比較均成正相關(guān)(P<0.05)。結(jié)論 PCT和CRP對新生兒感染性疾病的早期診斷,判斷感染程度,確定治療效果有重要價值,應(yīng)在臨床推廣使用。

[Abstract]Objective To study the value of combined detection of calcitonin(PCT) and C-reactive protein (CRP) in the diagnosis of neonatal infectious diseases.Methods Participants 44 newborns (observation group) and 44 normal newborns (control group) admitted to our hospital from March 2016 to April 2017 were enrolled in this study.Infections were collected before treatment 3 ml venous in children with disease and 3 ml venous blood in control group within 7 days after birth.PCT and CRP were measured in two groups.Venous blood before treatment and 10 days after treatment were collected in the observation group,CRP,neutrophil(NEUT) content,using Spearman rank correlation coefficient test PCT,CRP NEUT content correlation.Results The serum levels of PCT and CRP in the two groups were significantly higher than those in the control group (P<0.05).The positive rate of PCT and CRP in the observation group was significantly higher than that in the control group (P<0.05).The levels of PCT,CRP and NEUT in the observation group were significantly lower than those before treatment,the differences were statistically significant (P<0.05).The results of PCT,CRP and NEUT were based on the Spearman rank correlation coefficient.The results showed that PCT,CRP and NEUT were related (P<0.05).Conclusion PCT and CRP haveimportant value in the early diagnosis of neonatal infectious diseases,determine the degree of infection,and determine the therapeutic effect,and apply them to clinical practice.

新生兒感染性疾病是臨床常見病,該病病情發(fā)展快,病死率較高[1]。感染后的新生兒容易出現(xiàn)休克、敗血癥等癥狀,嚴(yán)重者甚至造成死亡。研究表明[2],早期診斷和及時治療對此病危重者的搶救及患兒預(yù)后均有重要價值。但由于患兒無特異性癥狀和體征,只能從實(shí)驗(yàn)室檢查來診斷,而病原體培養(yǎng)耗時長,患兒易錯過最佳治療期而影響預(yù)后[3]。血清降鈣素(PCT)和C-反應(yīng)蛋白(CRP)是近年來臨床上診斷感染性疾病較為常用的指標(biāo),PCT可以快速檢測感染的存在,CRP在感染發(fā)生6~8 h開始升高,且在24~48 h達(dá)到峰值,而在感染消除后會迅速下降[4]。本研究就PCT和CRP聯(lián)合檢測在新生兒感染性疾病診斷中的價值展開探討,旨在為臨床提供指導(dǎo)。
