JCEM:新生儿TSH延迟性升高的危险因素

2017-10-31 MedSci MedSci原创

促甲状腺激素(TSH)延迟性升高(dTSH)被定义为早产儿、低出生体重儿或患病新生儿在第二次新生儿筛查时TSH升高(在首次筛查时TSH正常),大多出现在新生儿重症监护室(NICU)。dTSH的发病是难以捉摸的。为确定在NICU中新生儿dTSH发病的风险因素,研究人员设计并完成了下述研究:这是一项回顾性总结研究,研究对象为八所大学附属医院的NICU中dTSH患儿。为每个患儿分配了两个对照组,分别为性

促甲状腺激素(TSH)延迟性升高(dTSH)被定义为早产儿、低出生体重儿或患病新生儿在第二次新生儿筛查时TSH升高(在首次筛查时TSH正常),大多出现在新生儿重症监护室(NICU)。dTSH的发病是难以捉摸的。

为确定在NICU中新生儿dTSH发病的风险因素,研究人员设计并完成了下述研究:

这是一项回顾性总结研究,研究对象为八所大学附属医院的NICU中dTSH患儿。为每个患儿分配了两个对照组,分别为性别或出生体重相匹配。单因素分析后的多元分析确定dTSH的危险因素。
主要观察指标:比较dTSH患儿和他们匹配的队列间的下列数据:
母亲的身体状况,NICU时治疗的类型、临床症状及各种医疗条件。


100名dTSH患儿和200名对照,及46个变量被纳入了该研究。通过单因素分析发现了12个dTSH的危险因素:剖宫产术、机械通气、动脉导管未闭(PDA)头孢噻肟、万古霉素、氟康唑、多巴胺、布洛芬,速尿、胰岛素及红细胞压积(PC)。通过多因素分析,确定了4个危险因素:PDA、万古霉素、胰岛素和速尿。在双胞胎中的有一名患有dTSH的26对双胞胎中,所有的变量都呈现出相似的风险。

虽然有一些变量对垂体-甲状腺轴功能产生了直接影响,所有这些变量反映在NICU管理中患儿临床症状的严重程度,这是dTSH的共同基础。
