青少年的生长激素释放-2测试显示,在异常发育激素缺乏和矮身群体中,生长激素 (GH) 的分泌量强. 目前的切断值可能需要修改,以便在这个人群中准确诊断GHD.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 增长激素生理学 生理学
- 诊断测试 诊断测试 诊断测试
背景情况:
- 生长激素释放-2 (GHRP2) 用于挑性生长激素 (GHT) 测试.
- GHRP2引发了强大的GH分泌反应,与其他GHT相比,需要更高的峰值GH水平切断值.
- 关于青少年群体GHRP2T反应的数据有限.
研究的目的:
- 在青少年的GHRP2负载测试 (GHRP2T) 中调查GHH峰值水平.
- 评估GHRP2T在区分生长障碍的原因方面的诊断效用.
主要方法:
- 对接受GHRP2T的青少年的临床数据的回顾性分析.
- 患者根据潜在疾病分为几组:有机/遗传性GHD (o/gGHD),异常性GHD (iGHD) 和矮身 (SS).
主要成果:
- 这项研究包括23名青少年 (12名/gGHD,3名iGHD,8名SS).
- 平均峰值GH水平为3.4 ng/mL (o/gGHD),88.9 ng/mL (iGHD) 和90.1 ng/mL (SS),在iGHD和SS组中显示出强大的反应.
- 两名患者符合GHRP2T标准,但没有其他GHT标准,这表明当前GHRP2T切断时,GHD的潜在诊断不足.
结论:
- 在患有IGHD和SS的青少年中,GHRP2T会引起强烈的GH反应.
- 青少年GHRP2T的确定的切断峰值GH水平可能需要重新评估,以确保GHD的准确诊断,特别是在边界反应的情况下.
- 需要进一步的研究来完善使用GHRP2T的青少年GH缺乏症的诊断标准.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Target Cell Response to Hormones
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...
