摘要

目的:探究甲泼尼松龙使用时机对儿童难治性肺炎支原体肺炎(RMPP)临床疗效的影响。方法:选取2023年1月至2025年1月间中国人民解放军联勤保障部队第九八九医院儿科收治的RMPP患儿82例,根据治疗时机的不同分为早期组和晚期组,早期组在患儿病程<5 d时使用甲泼尼松龙,晚期组在患儿病程≥5d时使用甲泼尼松龙,比较两组患儿治疗前后炎症因子[C反应蛋白(CRP)、白细胞介素(IL)-6、干扰素(IFN)-γ],肺功能[呼气峰值流速(PEF)、第1s用力呼气容积(FEV1)、用力肺活量(FVC)],免疫功能[免疫球蛋白(Ig)A、IgM及CD4+/CD8+],治疗后恢复情况(发热、咳嗽、肺部啰音改善时间及住院时间)、临床疗效及不良反应发生情况。结果:治疗后相较于晚期组,早期组患儿CRP、IL-6、IFN-γ等炎症因子显著低,PEF、FEV1、FVC水平显著高(P<0.05),两组患儿治疗后IgA、IgM、CD4+/CD8+等免疫指标水平比较差异无统计学意义(P>0.05),但两组患儿治疗后炎症因子、肺功能及免疫功能指标均较治疗前有明显改善(P<0.05),治疗后早期组发热、咳嗽、肺部啰音改善时间及住院时间较晚期组显著低(P<0.05),两组临床总有效率及不良反应发生率比较差异无统计学意义(P>0.05)。结论:甲泼尼松龙使用时机虽对RMPP患儿免疫功能、临床疗效及不良反应发生风险无明显影响,但尽早使用甲泼尼松龙有利于降低RMPP患儿的炎症因子水平,增强其肺功能,促进临床症状的改善。

Abstract

Objective: To investigate the impact of the timing of methylprednisolone administration on clinical efficacy in children with refractory Mycoplasma pneumoniae pneumonia (RMPP). Methods: A total of 82 children with RMPP admitted to the Department of Pediatrics, 989 Hospital of the Chinese PLA Joint Logistics Support Force from January 2023 to January 2025 were enrolled in this study. According to the timing of treatment, they were divided into the early group and the late group. The early group was treated with methylprednisolone when the disease course was less than 5 d, while the late group was treated with methylprednisolone when the disease course was 5 d or more. Comparisons were made between the two groups on inflammatory factors [C-reactive protein (CRP), interleukin (IL)-6, interferon (IFN)-γ], pulmonary function [peak expiratory flow (PEF), forced expiratory volume in the first second (FEV1), forced vital capacity (FVC)], immune function [immunoglobulin (Ig) A, IgM and CD4+/CD8+], recovery after treatment (improvement time of fever, cough and pulmonary rales, length of hospital stay), clinical efficacy and adverse reactions. Results: After treatment, the levels of CRP, IL-6 and IFN-γ in the early group were significantly lower than those in the late group. PEF, FEV1 and FVC were significantly higher than those in the late group (P<0.05). There was no statistically significant difference in IgA, IgM, or CD4+/CD8+ between the two groups after treatment (P>0.05). After treatment, inflammatory factors, pulmonary function, and immune function indicators in both groups were significantly improved (P<0.05). Compared with the late group after treatment, the early group showed significant reductions in the improvement time of fever, cough and pulmonary rales, and length of hospital stay (P<0.05). The total clinical effective rates and the incidence of adverse reactions of the two groups were comparable (P>0.05). Conclusion: Although the timing of methylprednisolone administration has no significant influence on immune function, clinical efficacy and risk of adverse reactions in children with RMPP, early use of methylprednisolone is conducive to lowering the levels of inflammatory factors, enhancing pulmonary function, and promoting the improvement of clinical symptoms.
