摘要:

目的 分析儿童难治性肺炎支原体肺炎(refractory M y c o p l a s m a p n e u m o n i a e pneumonia, RMPP)的危险因素。方法 选取2020年1月-2023年9月罗源县医院儿科收治的RMPP患儿67例为病例组,选取同时期临床资料完整且符合普通肺炎支原体肺炎诊断的患儿134例为对照组。两组初始治疗方案均为单用大环内酯类抗生素。采用单因素分析和多因素Logistic回归分析探究RMPP危险因素,并绘制受试者工作特征曲线评估危险因素的预测价值。结果 白蛋白下降、血小板下降、热峰大鱼等于40 ℃、乳酸脱氢酶大鱼等于500 U/L、肺部影像学呈大叶性肺炎是RMPP的危险因素;ROC曲线临界值分别为白蛋白<40 g/L(AUC=0.765,95% CI=0.803⁃0.901)、乳酸脱氢酶大鱼等于500 U/L(AUC=0.753,95% CI=0.772⁃0.877)、血小板计数小鱼120乘109/L(AUC=0.821,95% CI=0.761⁃0.868)、热峰≥40 ℃(AUC=0.750,95% CI=0.685⁃0.807)、肺部影像学呈大叶性肺炎(AUC=0.541,95% CI=0.469⁃0.611)。结论 当临床患儿出现白蛋白<40 g/L、血小板计数<120×109/L、热峰≥40 ℃、乳酸脱氢酶大鱼等于500 U/L、肺部影像学呈大叶性肺炎时应警惕为RMPP。

Abstract:

Objective To analyze risk factors for refractory M y c o p l a s m a p n e u m o n i a e pneumonia (RMPP) in children. Methods A total of 67 children with RMPP who were admitted in the Department of Paediatrics, Luoyuan County Hospital from January 2020 to September 2023 were enrolled in the case group. During the same period, 134 children with common M y c o p l a s m a p n e u m o n i a e pneumonia and complete clinical data were selected in the control group. Children in both groups were initially treated with macrolide antibiotics. Univariate and multivariate logistic regression analyses were used to analyze the risk factors for RMPP in children. The predictive potentials of risk factors for RMPP in children were assessed by plotting the receiver operating characteristic (ROC) curves. Results Decreased albumin, decreased platelet count, heat peak≥40 ℃, lactate dehydrogenase≥500 U/L, and lobar pneumonia changes on pulmonary imaging were risk factors for RMPP in children. The area under the curve (AUC) and cut-off value of risk factors were as follows: albumin<40 g/L (AUC=0.765, 95% C I=0.803-0.901), lactate dehydrogenase≥500 U/L (AUC=0.753, 95% C I=0.772-0.877), platelet count<120×109/L (AUC=0.821, 95% C I:0.761-0.868), heat peak≥40 ℃ (AUC=0.750, 95% C I: 0.685-0.807), and lobar pneumonia changes on pulmonary imaging (AUC=0.541, 95% C I: 0.469-0.611). Conclusion RMPP should be alerted in children with albumin<40 g/L, platelet count<120×109/L, heat peak≥40 ℃, lactate dehydrogenase≥500 U/L, and lobar pneumonia changes on pulmonary imaging.
