摘要:
目的 分析新生儿危重病例评分(neonatal critical illness score,NCIS)、脐血巨噬细胞移动抑制因子(migrationinhibitoryfactor,MIF)、白细胞介素-1β(interleukin-1β,IL-1β)对新生儿呼吸窘迫综合征(acute respiratory distress syndrome,ARDS)临床疗效评估价值。 方法 采用定群抽样的方法连续收集登记住本院新生儿科2023年1月至2024年12月住院的120例ARDS患儿作为观察组,另选取同期本院出生的120例健康新生儿作为对照组,以NCIS评分评估疾病严重程度,采集所有受检者出生即刻5 mL脐血,检测脐血MIF、IL-1β,比较两组NCIS评分、脐血MIF、IL-1β水平,根据肺部X线评估ARDS患儿疾病严重程度,比较轻度组、重度组NCIS评分、脐血MIF、IL-1β水平。120例ARDS患儿均给予经鼻间歇正压通气(nasal intermittent positive pressure ventilation,NIPPV)联合肺表面活性物质(pulmonarysurfactant,PS)治疗。比较有效组、无效组NCIS评分、脐血MIF、IL-1β水平,绘制受试者工作曲线(receiver operating characteristic curve,ROC),计算曲线下面积(area under curve,AUC),分析NCIS评分、脐血MIF、IL-1β对临床疗效的预测价值,单因素、多因素Logistic回归分析治疗无效的危险因素。 结果 观察组NCIS评分低于对照组(P < 0.05),观察组脐血MIF、IL-1β水平均高于对照组(P < 0.05)。重度组NCIS评分低于轻度组(P < 0.05),重度组脐血MIF、IL-1β水平均高于轻度组(P < 0.05)。无效组NCIS评分低于有效组(P < 0.05),无效组脐血MIF、IL-1β水平均高于有效组(P < 0.05)。NCIS评分、脐血MIF、IL-1β联合检测预测临床疗效AUC是0.798(95%CI: 0.702~0.947),灵敏度是93.13%,特异度是91.08%,均高于单一检测(71.85%、69.07%、76.24%、75.09%、74.82%、73.31%)(P < 0.05)。胎龄、出生体质量、产前使用糖皮质激素、治疗前PCaO2、PaO2、FiO2是导致治疗无效的危险因素(P < 0.05)。 结论 ARDS患儿脐血MIF、IL-1β水平越高,病情越重,治疗无效的风险越高,NCIS评分、脐血MIF、IL-1β联合检测可提高对临床疗效的预测效能,且胎龄、出生体质量、产前使用糖皮质激素、治疗前PCaO2、PaO2、FiO2等均为影响临床疗效的危险因素,应当引起临床重视与关注。 -

Abstract:Objective To analyze the clinical efficacy evaluation value of neonatal critical illness score (NCIS), umbilical cord blood macrophage migration inhibitory factor (MIF), and interleukin-1β (IL-1β) in neonatal acute respiratory distress syndrome (ARDS). Methods Using cluster sampling method, 120 neonates with ARDS hospitalized in the neonatal intensive care unit from January 2023 to December 2024 were consecutively enrolled as the observation group, while 120 healthy neonates born in the same period were selected as the control group. Disease severity was assessed using NCIS score. 5 mL of umbilical cord blood was collected immediately after birth from all the subjects to detect MIF and IL-1β levels. NCIS scores and umbilical cord blood MIF and IL-1β levels were compared between the two groups. ARDS patients were further stratified into mild and severe groups based on chest X-ray findings, and NCIS scores and umbilical cord blood MIF and IL-1β levels were compared between these subgroups. All 120 ARDS patients received treatment with nasal intermittent positive pressure ventilation (NIPPV) combined with pulmonary surfactant (PS). NCIS scores and umbilical cord blood MIF and IL-1β levels were compared between effective and ineffective treatment groups. Receiver operating characteristic (ROC) curves were plotted and area under curve (AUC) was calculated to analyze the predictive value of NCIS score, umbilical cord blood MIF, and IL-1β for clinical efficacy. Univariate and multivariate logistic regression analyses were performed to identify risk factors for treatment failure. Results NCIS scores in the observation group were lower than in the control group(P < 0.05), while umbilical cord blood MIF and IL-1β levels were significantly higher in the observation group compared to the control group (P < 0.05). NCIS scores in the severe group were lower than in the mild group (P < 0.05), while MIF and IL-1β levels were higher in the severe group(P < 0.05). NCIS scores in the ineffective group were lower than in the effective group (P < 0.05), while umbilical cord blood MIF and IL-1β levels were higher in the ineffective group (P < 0.05). The AUC of combined detection of NCIS score, umbilical cord blood MIF, and IL-1β for predicting clinical efficacy was 0.798 (95% CI: 0.702-0.947), with sensitivity of 93.13% and specificity of 91.08%, both significantly higher than single-factor detection (71.85%, 69.07%, 76.24%, 75.09%, 74.82%, 73.31%) (P < 0.05). Gestational age, birth weight, prenatal glucocorticoid use, and pretreatment PCaO2, PaO2 and FiO2 were identified as risk factors for treatment failure (P < 0.05). Conclusion In neonates with ARDS, higher umbilical cord blood MIF and IL-1β levels indicate more severe illness and higher risk of treatment failure. Combined detection of NCIS score, umbilical cord blood MIF, and IL-1β can improve the predictive efficacy for clinical outcomes. Gestational age, birth weight, prenatal corticosteroid use, and pretreatment PaCO2, PaO2, and FiO2 are all risk factors affecting clinical efficacy and warrant clinical attention and vigilance. -
