JAMA Pediatr:慢性肺疾病早产儿呼吸道合胞病毒感染年龄与住院风险的关系研究!

目前,尚不清楚美国儿科学会指南推荐的慢性肺疾病(CLD)早产儿接受呼吸道合胞病毒(RSV)免疫预防的年龄阈值(≤24个月)是否能正确识别住院发生RSV风险较高的新生儿。近期,一项发表在杂志JAMA Pediatr上的研究旨在确定与健康的不符合免疫预防的1个月足月儿相等的CLD早产儿RSV住院风险的年龄。此项研究对1999年1月1日至2010年12月31日期间,使用Medicaid记录(Medica

目前,尚不清楚美国儿科学会指南推荐的慢性肺疾病(CLD)早产儿接受呼吸道合胞病毒(RSV)免疫预防的年龄阈值(≤24个月)是否能正确识别住院发生RSV风险较高的新生儿。

近期,一项发表在杂志JAMA Pediatr上的研究旨在确定与健康的不符合免疫预防的1个月足月儿相等的CLD早产儿RSV住院风险的年龄。

此项研究对1999年1月1日至2010年12月31日期间,使用Medicaid记录(Medicaid Analytic eXtract文件)的1018593名健康足月婴儿和5181名CLD早产儿进行了回顾性队列研究。

研究者们使用生存分析框架内开发年龄趋势离散时间逻辑回归模型,调整包括使用免疫预防在内的协变量,比较了3至34个月的CLD早产儿(<32周胎龄)的住院风险年龄与1个月大的足月儿(37-41周胎龄)的住院风险。此项研究的主要结果是CLD早产儿RSV住院风险的年龄等于1个月健康足月儿的风险。

最终,此项研究共包括1018593名健康足月婴儿和5181名CLD早产儿;因为患者可以重新进入第二或第三季的队列,所以研究队列包括1880531个健康的足月婴儿(926206名女孩和954325名男孩;第一季进入时的平均年龄为12.6岁[9.6]个月)和8680个CLD婴儿(3519个女孩和5161个男孩;进入第一季的平均[SD]年龄,15.1 [9.1]个月)。

在足月同胞的婴儿中,1个月龄时所有协变量组平均住院风险为每1000个病人的季节-月9.0(95%可信区间,8.4-9.6) 。 CLD早产儿RSV的住院风险在18.5个月龄时(95%CI,15.6-22.8)与1个月的足月儿相似。

此项研究结果表明:CLD早产儿合并RSV住院风险的年龄临界值近似于健康足月儿,这支持了目前的美国儿科学会的实践指南,建议RSV预防直至最长24个月的年龄。

JAMA Pediatr:预防早产儿慢性肺疾病——INSURE治疗似乎优于NCPAP治疗

重要性:目前用来预防早产儿慢性肺疾病(CLD)的两大主要措施仍存在争议: 无创持续气道正压通气(NCPAP)及气管插管表面活性剂拔管(INSURE)。因呼吸窘迫综合症早产儿常需要表面活性剂治疗。目标:探讨INSURE或NCPAP单独预防CLD,死亡,或两者的有效性。数据源:研究者检索了2015年1月2日以前MEDLINE,EMBASE,Cochrane对照试验注册以及护理与医疗健康文献累积索引数据
