摘要 目的:探讨儿童重症肺炎的危险因素、病原体感染情况及mHLA-DR、IL-10表达水平。方法:选取我院重症监护病房收治的100例重症肺炎儿童作为观察组,分析病原体感染情况,并根据血培养结果将观察组分为细菌培养阳性组和阴性组。分析儿童重症肺炎感染发生的风险因素。同时选取同期行健康体检的儿童100例作为对照组,对比两组的IL-10、mHLA-DR表达水平。结果:病原检测阳性者63例,阳性率为63.00%,其中单纯病毒感染23例,2种以上病毒感染合计11例;单纯细菌感染合计17例,2种以上细菌感染合计5例,单纯肺炎支原体感染合计4例;混合感染3例。单因素分析结果显示:儿童年龄、住院时间、发病季节、非单人间病房及抗生素不合理应用与其发生重症肺炎感染存在显著相关性,而两组性别、贫血史与先天性心脏病史等情况比较,差异显著(P>0.05)。logistic回归分析结果显示:年龄≤2岁、住院时间≥2 w、春夏季节、非单人间住房及抗生素不合理应用均是导致儿童发生重症肺炎的独立危险因素。较对照组,观察组IL-10水平明显更高,而mHLA-DR水平显著更低(P<0.05)。结论:病毒感染是导致儿童重症肺炎的常见病原体,其次为细菌感染。此疾病在≤2岁的幼儿中较为多见,秋冬季节较为频发,且与住院时间、非单人间病人及抗生素不合理应用等影响因素密切相关,同时患儿的免疫炎症机制紊乱,检测IL-10、mHLA-DR水平有利于防治儿童重症肺炎。
