摘要
目的 评价多西环素(DOX)不同给药时间对大环内酯耐药肺炎支原体肺炎(MR-MPP)患儿的影响.方法 分析2022年1月至2023年12月杭州市儿童医院诊断为MR-MPP患儿临床资料.根据治疗方案分为DOX组、静脉注射阿奇霉素改为口服DOX(ATD)组和单独静脉注射阿奇霉素(AZI)组.ATD组根据阿奇霉素治疗时间分为ATD1组(＜3 d)和ATD2组(≥3 d).比较各组的临床症状,并采用倾向性评分匹配(PSM)对DOX+ATD1组和ATD2组患儿进行1:1匹配分析.结果 研究共纳入156例MR-MPP患儿,DOX组、ATD组和AZI组分别为25例、85例和46例.与ATD组和AZI组相比,DOX组治疗后住院时间和发热时间较短,胸片改善率较高,糖皮质激素使用率低(P＜0.05).DOX组和ATD1组住院时间、治疗后发热持续时间和糖皮质激素使用率均低于ATD2组,且96 h退热率和胸部X线改善率高于ATD2组(P＜0.05).DOX组72 h内退热率高于ATD1组和ATD2组(P＜0.05).PSM分析显示DOX+ATD1组的住院时间、治疗后发热时间和糖皮质激素使用率均低于ATD2组,72 h退热率高于ATD2组(均P＜0.05).治疗期间未观察到与DOX相关的不良反应.结论 早期(72h内)口服DOX可显著改善MR-MPP患儿的临床疗效.
Abstract
Objective To evaluate the impact of different dosing times of doxycycline(DOX)on children with macrolide-resistant Mycoplasma pneumoniae pneumonia(MR-MPP).Methods Clinical data of children diagnosed with MR-MPP at Hangzhou Children's Hospital from January 2022 to December 2023 were analyzed.Children were divided into three groups based on treatment regimens:the doxycycline(DOX)group,the intravenous azithromycin converted to oral DOX(ATD)group,and the intravenous azithromycin alone(AZI)group..The ATD group was further divided into ATD1 group(＜3 days)and ATD2 group(＞3 days)according to the duration of azithromycin treatment.Clinical symptoms of each group were compared,and propensity score matching(PSM)analysis was used for adjustment.Results A total of 156 children with MR-MPP were included in the study,with 25 in the DOX group,85 in the ATD group,and 46 in the AZI group.Compared with the ATD and AZI groups,the DOX group had a shorter hospital stay and fever duration,higher chest radiograph improvement rate,and lower glucocorticoid usage rate(P＜0.05).The DOX group and ATD1 group had lower hospital stays,post-treatment fever durations,and glucocorticoid usage rates than the ATD2 group,and higher 96-hour fever resolution rates and chest X-ray improvement rates than the ATD2 group(P＜0.05).The DOX group had a higher fever resolution rate within 72 hours compared to the ATD1 and ATD2 groups(P＜0.05).PSM analysis showed that the DOX-ATD1 group had a lower hospital stay,post-treatment fever duration,and glucocorticoid usage rate than the ATD2 group,and a higher 72-hour fever resolution rate than the ATD2 group(all P＜0.05).No adverse reactions related to DOX were observed during the treatment period.Conclusion Early oral administration of DOX within 72 hours can significantly improve the clinical efficacy in children with MR-MPP.
