概括
甲状腺功能测试 (TFT) 在治疗甲状腺素替代的甲状腺功能低下患者中显示,在两年内,大约六分之十的甲状腺功能低下. 男性性别和肥胖与不足的替代性有关,较短的TFT间隔增加了次优控制的风险.
科学领域:
- 内分泌学 在内分泌学.
- 初级医疗保健医学 一级医疗保健医学
- 药物治疗监测 药物治疗监测
背景情况:
- 甲状腺功能低下症的长期管理需要定期进行甲状腺功能测试 (TFT),根据指导方针每6-12个月进行一次监测.
- 这项研究评估了甲状腺功能状况,影响因素,以及治疗甲状腺素替代治疗的初级保健患者在两年内最佳的TFT间隔.
研究的目的:
- 在为期两年的初级保健随访期间,确定甲状腺功能状态的甲状腺功能下降患者甲状腺素替代.
- 为了确定与非最佳甲状腺控制相关的因素.
- 为了评估TFT监控的最佳间隔.
主要方法:
- 新加坡成人甲状腺功能低下症患者的回顾性队列研究 (2017年7月至2020年6月).
- 甲状腺状况被分类为补充不足 (TSH ≥3.70mIU/L),补充过多 (TSH ≤0.65mIU/L) 或安甲状腺 (TSH 0.65-3.70mIU/L).
- 包括分步后勤回归和卡普兰-梅尔分析在内的统计分析被用来确定因素,并根据监测间隔对结果进行比较.
主要成果:
- 对5,749名受试者的分析显示,两年后,61.9%的受试者是甲状腺功能良好的,29.5%的受试者是甲状腺功能不足的,8.6%的受试者是甲状腺功能过度的.
- 甲状腺素不足的替代与男性性别和肥胖症有显著的关联.
- 较短的TFT监测间隔 (≤12个月) 不太可能检测到不足或过多的替换,而优甲状腺患者的比例在6,12和24个月的间隔下翻了一番.
结论:
- 大约60%的甲状腺功能低下症患者在甲状腺素替代药物治疗中,在两年内在初级保健中获得了euthyroid状态.
- 男性性别和肥胖是甲状腺素不足的风险因素.
- 该研究表明,目前的TFT监测间隔可能不适合所有患者,较短的间隔可能会掩盖次优的甲状腺控制.

Synthesis and Regulation of Thyroid Hormones
4.2K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Functions of Thyroid Hormones
2.6K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

The Thyroid Gland
3.6K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Major Hormones and Their Functions
334
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...

Hormones and Bone Tissue
2.6K
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...

Target Cell Response to Hormones
2.9K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
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...
