患有支气管肺功能障碍 (BPD) 的早产婴儿在第一周内显示出较高水平的皮质醇前体和皮质醇相对于皮质醇. 这表明上腺轴无法满足高的皮质醇需求,容易发炎和BPD.
科学领域:
- 新生儿生理学 新生儿生理学
- 内分泌学 在内分泌学.
- 肺部医学 肺部医学
背景情况:
- 系统性炎症是支气管肺功能障碍 (BPD) 发展的关键因素.
- 皮质醇通常减少炎症,但早产婴儿在出生后表现出皮质醇不足和前体丰富.
- 这种上腺模式在BPD病变发生过程中的作用尚不清楚.
研究的目的:
- 调查是否高的皮质醇前体和皮质醇相对于皮质醇在早产婴儿有助于BPD的发展.
- 分析妊娠30周之前出生婴儿的上腺功能模式.
主要方法:
- 皮质醇,皮质素,17-OH孕激素 (17-OHP) 和11-脱氧皮质醇的血清水平通过液态染色学-并联质量谱测量.
- 测量是在产后第1,3,7,14和28天进行的.
- 经月经后36周,BPD诊断得到证实.
主要成果:
- 在65名婴儿中,32名 (49%) 患有BPD.
- 患有BPD的婴儿在生命的第一周内相对于皮质醇,17-OHP,11-脱氧皮质醇和皮质醇相对较高.
- 这种荷尔蒙模式在出生时或在第7天之后没有观察到.
结论:
- 患有BPD的早产婴儿在第一周表现出较高的皮质醇前体和相对于皮质醇的皮质醇.
- 这表明下丘脑-垂体-上腺轴被激活,无法满足高皮质醇需求.
- 这种葡萄糖皮质激素失衡可能会使婴儿易受炎症和随后的BPD.
