血清1,25(OH)2D3、EOS%联合APACHEⅡ评分评估小儿肺炎病情严重程度的价值
Clinical value of serum 1,25-dihydroxyvitamin D3, eosinophil percentage, and APACHE Ⅱ score in assessing the severity of pediatric pneumonia
目的 探讨血清1,25二羟维生素D3[1,25(OH)2D3]和嗜酸性粒细胞百分比(EOS%)联合急性生理与慢性健康评价评分表(APACHEⅡ)评估在小儿肺炎病情严重程度的价值。 方法 选取2019年10月—2023年12月秦皇岛市妇幼保健院收治的123例小儿肺炎患者作为观察组,根据病情严重程度再分为轻症组(79例)和重症组(44例)。同时选取60例该院同期体检健康儿童作为对照组。比较不同组别的血清1,25(OH)2D3、EOS%表达水平和APACHEⅡ评分,比较血清1,25(OH)2D3、EOS%、APACHEⅡ评分与肺功能指标[潮气量(VT)、呼吸频率(RR)、吸呼比(TI/TE)、呼气峰时长占总呼气时间百分比(TPTEF/TE)]的相关性。通过受试者工作特征(ROC)曲线评估1,25(OH)2D3、EOS%和APACHEⅡ评分的联合使用在评估疾病严重程度的有效性。 结果 观察组1,25(OH)2D3水平低于对照组(P <0.05),血清EOS%高于对照组(P <0.05)。重症组1,25(OH)2D3水平低于轻症组(P <0.05),EOS%和APACHEⅡ评分均高于轻症组(P <0.05)。重症组患儿VT、TI/TE及TPTEF/TE低于轻症组(P <0.05),RR高于轻症组(P <0.05)。Pearson相关性分析结果显示,1,25(OH)2D3水平与VT、TI/TE、TPTEF/TE均呈正相关(r =0.395、0.478、0.344,均P <0.05),与RR呈负相关(r =-0.236,P <0.05)。EOS%与VT、TI/TE、TPTEF/TE均呈负相关(r =-0.319、-0.290、-0.308,均P <0.05),与RR呈正相关(r =0.301,P <0.05)。APACHEⅡ评分与VT、TI/TE、TPTEF/TE呈负相关(r =-0.285、-0.503、-0.302,均P <0.05),与RR呈正相关(r =0.324,P <0.05)。ROC曲线分析结果显示,1,25(OH)2D3、EOS%和APACHE Ⅱ评分联合预测的曲线下面积最大,为0.993(95% CI:0.983,1.000);敏感性最高,为90.9%(95% CI:0.783,0.975);特异性最高,为100.0%(95% CI:0.954,1.000)。 结论 血清1,25(OH)2D3水平和EOS%联合APACHEⅡ评分与小儿肺炎的严重程度密切相关,3项指标联合检测可有效评估病情严重程度。
Objective To analyze the clinical value of serum 1,25-dihydroxyvitamin D3 [1,25(OH)2D3] and eosinophil percentage (EOS%) combined with the Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score in assessing the severity of pediatric pneumonia. Methods A total of 123 pediatric pneumonia patients admitted to Qinhuangdao Maternal and Child Health Hospital from October 2019 to December 2023 were enrolled and divided into the mild (n = 79) and severe (n = 44) groups based on disease severity. Additionally, 60 healthy children undergoing routine health examinations in the hospital during the same period served as controls. Serum levels of 1,25(OH)2D3, EOS%, and APACHE Ⅱ scores were compared among the groups, and their correlations with pulmonary function parameters [tidal volume (VT), respiratory rate (RR), inspiratory-to-expiratory ratio (TI/TE), and time to peak expiratory flow as a percentage of total expiratory time (TPTEF/TE) ] were analyzed. The predictive efficacy of combining 1,25(OH)2D3, EOS%, and APACHE Ⅱ scores for disease severity was evaluated using the receiver operating characteristic (ROC) curve analysis. Results Compared with the controls, the pneumonia patients exhibited significantly lower serum 1,25(OH)2D3 levels and higher EOS% (P < 0.05). The severe group showed lower 1,25(OH)2D3 levels but higher EOS% and APACHE Ⅱ scores than the mild group (P < 0.05). The children in the severe group had reduced VT, TI/TE, and TPTEF/TE, along with elevated RR, compared with the mild group (P < 0.05). Pearson correlation analysis indicated positive correlations between 1,25(OH)2D3 levels and VT, TI/TE, and TPTEF/TE (r = 0.395, 0.478 and 0.344, all P < 0.05), but a negative correlation with RR (r = -0.236, P < 0.05). EOS% was negatively correlated with VT, TI/TE, and TPTEF/TE (r = -0.319, -0.290 and -0.308, all P < 0.05), and positively correlated with RR (r = 0.301, P < 0.05). APACHE II scores were negatively correlated with VT, TI/TE, and TPTEF/TE (r = -0.285, -0.503 and -0.302, all P < 0.05), and positively correlated with RR (r = 0.324, P < 0.05). ROC curve analysis showed that the combined prediction using 1,25(OH)₂D₃, EOS%, and APACHE II scores yielded the largest area under the curve 0.993 (95% CI: 0.983, 1.000), with the highest sensitivity 90.9% (95% CI: 0.783, 0.975) and specificity 100.0% (95% CI: 0.954, 1.000). Conclusion Serum 1,25(OH)2D3, EOS% and the APACHE Ⅱ score are closely associated with the severity of pediatric pneumonia, and their combination could serve as effective biomarkers for clinical assessment.
