概括
患有GH缺乏症的儿童的峰值生长激素 (PGH) 水平与更好的脂质样本和较低的肝酶有关,独立于BMI. 这突出了PGH.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 代谢障碍 代谢障碍 代谢障碍
- 生长激素研究 研究生生长激素研究
背景情况:
- 青春期前儿童的生长激素缺乏症 (GHD) 可能会影响代谢健康.
- 了解生长激素和代谢标志物之间的关系对于管理GHD至关重要.
- 肝硬化和代谢失调是GHD的潜在并发症.
研究的目的:
- 为了研究刺激的峰值生长激素 (PGH) 水平和GHD的青春期前儿童的代谢参数之间的关联.
- 探索PGH与葡萄糖/脂质新陈代谢以及肝脏肥胖症之间的关系.
- 要确定这些关联是否根据身体质量指数 (BMI) 状态有所不同.
主要方法:
- 69名患有GHD的青春期前儿童被分为超重/肥胖 (BMI≥85百分位) 和正常的BMI组.
- 评估了PGH水平与代谢标志物之间的关联,包括HOMA-IR,脂质样本 (LDL-C,HDL-C,TG),AST和ALT.
- 进行了多变量分析,根据年龄,性别,BMI SDS,HOMA-IR和TG水平进行了调整.
主要成果:
- 与正常的BMI儿童相比,患有GHD的超重/肥胖儿童的LDL胆固醇水平显著更高.
- 孕激素水平与BMI,SDS和ALT有负相关性,与HDL-C有正相关性.
- 多变量分析证实PGH与HDL-C正相关,与ALT负相关,独立于其他因素.
结论:
- 在患有GHD的青春期前儿童中,刺激的PGH水平与改善的脂质样本 (更高的HDL-C) 和降低的肝酶水平 (更低的ALT) 显著相关.
- 这些关联即使在PGH水平处于正常范围内并且独立于BMI状态时也存在.
- 这些发现表明,PGH在代谢调节中发挥着作用,除了对生长的直接影响.

Nature and Nurture
20.8K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...

Major Hormones and Their Functions
718
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Signs of Puberty
614
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

Regulation of Metabolism
9.9K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Hypoglycemia and Glucagon
338
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...
