摘要:

目的:探讨支气管哮喘(BA)急性发作患儿白细胞计数/平均血小板体积(WMR)对短期预后的预测价值及相关危险因素分析。方法:选取20226月至202312月某院收治的94BA急性发作患儿作为研究组,另选取同期年龄相匹配的健康体检者52例作为对照组,比较两组白细胞计数(WBC)、平均血小板体积(MPV)、WMR水平。根据患儿病情严重程度分为轻度组、中度组和重度组,比较3组患儿临床资料、实验室指标及WMR水平。根据患儿短期预后分为预后良好组和预后不良组,比较两组患儿临床资料、实验室指标及WMR水平。绘制受试者工作特征曲线(ROC),分析WMR对短期预后的预测价值。采用多因素Logistic回归分析BA急性发作患儿短期预后的危险因素。结果:研究组患儿血清WBCMPVWMR水平均高于对照组(P<0.05);重度组患儿WBCMPVWMR水平均高于中度组和轻度组患儿(P<0.05);预后不良组和预后良好组在过敏史、呼吸道反复感染史、WMR方面差异均有统计学意义(P<0.05)。ROC曲线结果显示,WMRBA患儿短期预后预测的AUC0.72195%CI0.619~0.809,特异度为60.27%,敏感度为76.19%。二元Logistic回归分析结果显示,过敏史(OR=5.484P=0.006)、呼吸道反复感染史(OR=5.695P=0.015)、WMR>0.93OR=4.053P=0.022)均为BA急性发作患儿短期预后的独立危险因素(P<0.05)。结论:BA急性发作患儿血清WMR水平升高,且与病情相关,其在预测BA急性发作患儿短期预后具有一定预测价值。

Abstract:

Objective: To explore the predictive value of white blood cell count/mean platelet volume WMR in short-term prognosis and the risk factors in children with acute attack of bronchial asthma BA.Methods: 94 children with acute attack of BA and 52 healthy children controls with matched age were enrolled as the study group and the control group between June 2022 and December 2023 respectively. The levels of white blood cell count WBC), mean platelet volume MPV and WMR were compared between the two groups. According to disease severity children in the study group were divided into mild group moderate group and severe group. The clinical data laboratory indexes and WMR level of patients in the three groups were compared. According to short-term prognosis the patients were divided into the good prognosis group and the poor prognosis group. The clinical data laboratory indexes and WMR revels in the two groups were compared. The predictive value of WMR for short-term prognosis was analyzed by receiver operating characteristic ROC curves and risk factors of short-term prognosis were analyzed by multivariate Logistic regression analysis.Results: The levels of serum WBC MPV and WMR in the study group were higher than those in the control group P<0.05), and these indicators were higher in the severe group than in the moderate group and the mild group P<0.05. There were significant differences in allergy history history of repeated respiratory tract infection and WMR level between the poor prognosis group and the good prognosis group P<0.05. ROC curves analysis showed that AUC 95%CI specificity and sensitivity of WMR for predicting short-term prognosis of BA children were 0.721 0.619-0.809 60.27% and 76.19% respectively. Binary Logistic regression analysis showed that allergy history OR=5.484P=0.006), history of repeated respiratory tract infection OR=5.695P=0.015 and WMR >0.93 OR=4.053P=0.022 were independent risk factors of short-term prognosis in children with acute attack of BA P<0.05.Conclusion: The level of serum WMR increases in children with acute attack of BA. It is correlated with disease severity and has certain predictive value for short-term prognosis.
