摘要/Abstract

摘要：

肺炎支原体肺炎(Mycoplasma pneumoniae pneumonia,MPP)是我国儿童常见社区获得性肺炎,重症MPP可遗留严重后遗症。年龄是决定MPP临床表型与免疫应答的关键变量:<2岁患儿适应性免疫尚未完善,以喘息、弥漫性斑片影为主,免疫应答依赖天然免疫且呈1型辅助性T细胞/2型辅助性T细胞因子失衡;2~5岁为重症高发期,免疫系统呈现促炎因子(白细胞介素-6、干扰素γ等)显著升高、抗炎因子(白细胞介素-4、白细胞介素-10)降低的失衡状态;>5岁患儿适应性免疫应答强烈,易发生大叶性实变、肺坏死及肺外并发症。治疗策略需遵循年龄分层原则:抗生素选择需考虑耐药年龄差异,支气管镜灌洗应依据年龄差异把握指征。并发症谱与随访策略亦应随年龄调整。未来需深化年龄分层干预研究,推动MPP精准诊疗发展。
