目的

探讨脑血流动力学参数联合血清高敏C反应蛋白(hs-CRP)、白细胞介素-6(IL-6)水平对早产儿脑损伤(BIPI)的早期诊断价值。

方法

选择黄冈市中心医院新生儿重症监护室自2021年1月至2024年1月收治的胎龄≤32周、体质量<1500 g的94例早产儿为研究对象。出院前或矫正胎龄36周完善颅脑MRI,根据MRI检查结果和临床表现将患儿分为BIPI组(36例)和非BIPI组(58例)。分析2组患儿的围生期一般资料,以及生后第3天大脑中动脉(MCA)血流动力学参数[收缩期峰值流速(Vs)、阻力指数(RI)]与hs-CRP、IL-6水平;采用二元Logistic回归分析探讨BIPI发生的危险因素,并采用受试者工作特征(ROC)曲线分析血清hs-CRP、IL-6水平、MCA血流动力学参数及联合预测对早期BIPI的诊断价值。

结果

BIPI组患儿3 d内扩容、3 d内高血糖发生率及生后第3天Vs、RI、hs-CRP、IL-6水平均较非BIPI组高,差异均有统计学意义(P<0.05)。Logistic回归分析显示,3 d内扩容、3 d内高血糖,以及生后第3天Vs、RI、hs-CRP、IL-6是早期BIPI发生的独立危险因素。ROC曲线分析显示,血清hs-CRP、IL-6水平、Vs、RI单独及联合预测BIPI的曲线下面积(AUC)(95%CI)分别为0.762(0.659~0.864)、0.780(0.674~0.885)、0.785(0.675~0.896)、0.696(0.572~0.821)和0.940(0.894~0.985);与血清hs-CRP、IL-6水平和Vs、RI任意检测项目比较,联合预测效能更高(P<0.05)。

结论

血清hs-CRP、IL-6水平联合Vs、RI对于早期BIPI具有良好的预测效能。

Objective

To explore the value of cerebral hemodynamics parameters combined with serum levels of High-sensitivity C-reactive protein (hs-CRP) and interleukin-6 (IL-6) in the early diagnosis of brain injury in premature infants (BIPI).

Methods

From January 2021 to January 2024, 94 premature infants with gestational age≤32 weeks and birth weight<1500 g were admitted to the Neonatal Intensive Care Unit of Huanggang Central Hospital. Cranial magnetic resonance imaging (MRI) was performed before discharge or at a corrected gestational age of 36 weeks. The diagnosis of BIPI was based on Expert Consensus on Diagnosis and Prevention of Brain Injury in Premature Infants. Infants were assigned to the BIPI group (n=36) and non-BIPI group (n=58). The cerebral hemodynamic parameters of middle cerebral artery (MCA) including peak systolic velocity (Vs) and resistance index (RI) and serum levels of hs-CRP and IL-6 were analyzed and compared between the two groups on the third postnatal day. Binary Logistic regression analysis was used to identify risk factors for BIPI. The diagnostic value of serum hs-CRP and IL-6 levels, hemodynamic parameters of MCA (Vs, RI), and their combination for early BIPI were evaluated using receiver operating characteristic (ROC) curve analysis.

Results

Univariate Analysis showed that the incidence of volume expansion and hyperglycemia within 3 d, Vs, RI, hs-CRP and IL-6 levels in BIPI group were higher than those in non-BIPI group (P<0.05). Logistics regression analysis showed that volume expansion and hyperglycemia within 3 d, Vs, RI, hs-CRP, IL-6 were independent risk factors of BIPI on the third postnatal day. ROC curve analysis shows that the areas under the curve (AUC) (95%CI) of serum hs-CRP, IL-6 level, Vs, RI alone and the combined prediction of BIPI were 0.762 (0.659-0.864), 0.780 (0.674-0.885), 0.785 (0.675-0.896), 0.696 (0.572-0.821), and 0.940 (0.894-0.985), respectively, compared with hs-CRP, IL-6, Vs and RI, the AUC of the combined prediction was higher (P<0.05).

Conclusions

The combination of serum hs-CRP, IL-6, Vs and RI has good predictive efficacy for early diagnosis of BIPI.
