孟鲁司特钠联合N-乙酰半胱氨酸治疗儿童呼吸道合胞病毒下呼吸道感染的疗效分析
Efficacy analysis of montelukast sodium combined with N-acetylcysteine in treating children with respiratory syncytial virus lower respiratory tract infection
目的 探讨呼吸道合胞病毒(RSV)下呼吸道感染儿童采用孟鲁司特钠联合N-乙酰半胱氨酸治疗的疗效。 方法 选取2024年7月—2025年8月天津市人民医院收治的RSV下呼吸道感染患儿100例,随机分为试验组和对照组,分别有51、49例。对照组采用孟鲁司特钠治疗,每次口服4 mg,1次/d。试验组在对照组的基础上采用N-乙酰半胱氨酸治疗,雾化吸入N-乙酰半胱氨酸,1次/d。两组均持续治疗1周。对比两组体征及临床症状缓解时间、免疫功能、肺功能、炎症反应、临床疗效及不良反应。 结果 试验组呼吸困难、气促、经皮血氧饱和度下降、喘息症状缓解时间均短于对照组(P <0.05)。对照组与试验组治疗前CD4+、CD3+、CD4+/CD8+、第1秒内用力呼气容积(FEV1)、用力肺活量(FVC)及每分钟最大通气量(MVV)、血清淀粉样蛋白A(SAA)、P物质(SP)、白细胞介素-10(IL-10)比较,差异均无统计学意义(P >0.05)。试验组治疗后CD4+、CD3+、CD4+/CD8+、MVV、FVC、FEV1、IL-10均高于对照组(P <0.05),SAA、SP均低于对照组(P <0.05)。试验组治疗前后CD4+、CD3+、CD4+/CD8+、MVV、FVC、FEV1、SAA、SP、IL-10差值均大于对照组(P <0.05)。试验组总有效率高于对照组高(P <0.05)。两组不良反应总发生率比较,差异无统计学意义(P >0.05)。 结论 孟鲁司特钠与N-乙酰半胱氨酸联用对RSV下呼吸道感染儿童下呼吸道炎症显现良好疗效,可显著加快临床症状缓解速度,改善肺通气功能与免疫指标水平,并有效抑制血清炎症因子释放,且治疗期间未见严重药物不良反应。
Objective To analyze the efficacy of montelukast sodium combined with N-acetylcysteine in the treatment of children with respiratory syncytial virus (RSV) lower respiratory tract infection. Methods The 100 children with RSV lower respiratory tract infection admitted to our hospital from July 2024 to August 2025 were randomly divided into a control group and an experimental group, with 51 and 49 cases in each group, respectively. The control group received montelukast sodium (4 mg orally, once daily). The experimental group received additional N-acetylcysteine (aerosol inhalation, once daily) besides the control group's treatment. Both groups were treated for one week. The relief times of signs and clinical symptoms, immune function, pulmonary function, inflammatory response, clinical efficacy, and adverse reactions were compared between the two groups. Results The relief times of dyspnea, shortness of breath, decreased percutaneous oxygen saturation, and wheezing symptoms were significantly shorter in the experimental group than in the control group (P < 0.05). Before treatment, no significant differences were observed between the control and experimental groups in CD4+ T-cell levels, CD3+ T-cell levels, CD4+/CD8+ ratio, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), maximum voluntary ventilation (MVV), serum amyloid A (SAA), substance P (SP), or interleukin-10 (IL-10) levels (P > 0.05). After treatment, the experimental group showed significantly higher CD4+ T-cell levels, CD3+ T-cell levels, CD4+/CD8+ ratio, MVV, FVC, FEV1, and IL-10 levels than the control group (P < 0.05), whereas SAA and SP levels were significantly lower in the experimental group (P < 0.05). The pre- to post-treatment changes in CD4+ T-cell levels, CD3+ T-cell levels, CD4+/CD8+ ratio, MVV, FVC, FEV1, and levels of SAA, SP, and IL-10 were greater in the experimental group than in the control group (P < 0.05). The overall response rate was higher in the experimental group than in the control group (P < 0.05). No significant difference was found in the overall incidence of adverse reactions between the two groups (P > 0.05). Conclusion The combination of montelukast sodium and N-acetylcysteine demonstrates favorable therapeutic efficacy in children with RSV lower respiratory tract infection. It can significantly accelerate the resolution of clinical symptoms, improve pulmonary ventilation function and immune indicators, and effectively suppress the release of serum inflammatory mediators, without causing serious drug-related adverse events during treatment.
