摘要:
目的 讨论血清前B细胞克隆增强因子(pre-B cell colony-enhancing factor,PBEF)、Kruppel样转录因子2(kruppel like factor 2,KLF2)、白介素-26(Interleukin-26,IL-26)与重症肺炎(severe pneumonia,SP)患儿病情严重程度及预后转归的关系。 方法 选择西安市儿童医院2023年3月-2025年3月收治的180例SP患儿作为研究对象,使用ELISA试剂盒分别检测血清中PBEF、KLF2、IL-26的蛋白水平;根据急性生理与慢性健康评分Ⅱ(acute physiology and chronic health score,APACHE Ⅱ评分)判定患儿的病情严重程度并分组为非危重症组(n = 60)、危重症组(n = 75)和极危重症组(n = 45);根据SP患儿预后分为预后良好组(n = 127)和预后不良组(n = 53);血清PBEF、KLF2、IL-26水平与APACHE Ⅱ评分的相关性采用Pearson法分析;多因素Logistics回归分析影响SP患儿预后转归的因素;ROC曲线分析血清PBEF、KLF2、IL-26水平对SP患儿预后转归的预测价值。 结果 与非危重症组比较,危重症组、极危重症组APACHE Ⅱ评分及血清PBEF、IL-26水平升高(P < 0.05),血清KLF2水平均低(P < 0.05);与危重症组比较,极危重症组APACHE Ⅱ评分及血清PBEF、IL-26水平升高,血清KLF2水平降低(P < 0.05);SP患儿血清PBEF、IL-26水平与APACHE Ⅱ评分呈正相关,血清KLF2水平与APACHE Ⅱ评分呈负相关(P < 0.05);预后不良组较预后良好组极危重症患者比例、APACHE Ⅱ评分及血清PBEF、IL-26水平升高,血清KLF2水平降低(P < 0.05);血清PBEF、IL-26水平升高,KLF2水平降低是SP患儿发生预后不良的危险因素(P < 0.05);血清PBEF、KLF2、IL-26水平单独及联合预测患儿预后不良的AUC分别为0.769、0.820、0.814、0.933,三者联合预测价值更高(Z = 4.112、3.893、4.035,P < 0.001)。 结论 伴随SP患儿病情严重程度的增加,血清PBEF、IL-26水平升高,KLF2水平降低,三者可作为预测患儿预后转归的指标。 -

Abstract:Objective To discuss the relationship between serum pre-B cell colony-enhancing factor (PBEF), Kruppel like factor 2 (KLF2), interleukin-26 (IL-26) and the severity and prognosis of severe pneumonia (SP) in children. Methods A total of 180 children with SP admitted to Xi 'an Children's Hospital from March 2023 to March 2025 were selected as the research subjects. The protein levels of PBEF, KLF2 and IL-26 in serum were detected respectively using ELISA kits. The severity of the children's conditions was determined based on the acute physiology and chronic health score Ⅱ (APACHE Ⅱ score), and they were grouped into the non-critical group (n = 60), the critical group (n = 75), and the extremely critical group (n = 45). According to the prognosis of children with SP, they were divided into the good prognosis group (n = 127) and the poor prognosis group (n = 53). The correlations between the levels of serum PBEF, KLF2 and IL-26 and the APACHE Ⅱ score were analyzed by the Pearson method. Multivariate logistic regression analysis was conducted to analyze the factors influencing the prognosis and outcome of children with SP. ROC curve was used to analyze the predictive value of serum PBEF, KLF2 and IL-26 levels for the prognosis and outcome of children with SP. Results Compared with the non-critical group, the APACHE Ⅱ score, serum PBEF and IL-26 levels in the critical group and the extremely critical group were all increased (P < 0.05), and the serum KLF2 level was all decreased (P < 0.05). Compared with the critical group, the APACHE Ⅱ score and the levels of serum PBEF and IL-26 in the extremely critical group were increased, while the level of serum KLF2 was decreased (P < 0.05). The levels of serum PBEF and IL-26 in children with SP were positively correlated with the APACHE Ⅱ score, while the level of serum KLF2 was negatively correlated with the APACHE Ⅱ score (P < 0.05). The proportion of extremely critical patients, APACHE Ⅱ score, serum PBEF and IL-26 levels in the poor prognosis group were increased compared with those in the good prognosis group, while the serum KLF2 level was decreased (P < 0.05). The elevated levels of serum PBEF and IL-26 and the decreased level of KLF2 are risk factors for poor prognosis in children with SP (P < 0.05). The AUCs of serum PBEF, KLF2, and IL-26 levels alone and in combination for predicting poor prognosis in children were 0.769, 0.820, 0.814, and 0.933, respectively. The combined predictive value of the three was higher (Z=4.112, 3.893, 4.035, all P < 0.001). Conclusion With the increase of the severity of the disease in children with SP, the levels of serum PBEF and IL-26 were increased, and the level of KLF2 was decreased. The three can be used as indicators for predicting the prognosis and outcome of children. -
