概括
补充剂有效降低甲状腺刺激激素 (TSH) 和甲状腺过氧化酶抗体 (TPOAb) 在哈希莫托甲状腺炎 (HT) 患者. 这种微量元素是安全的,可能有助于管理HT,特别是那些没有接受甲状腺激素替代疗法的人.
科学领域:
- 内分泌学 在内分泌学.
- 营养科学 营养科学
- 自免疫性疾病 自免疫性疾病
背景情况:
- 哈西莫托甲状腺炎 (HT) 是充足地区甲状腺功能低下的主要原因.
- 是一种必不可少的微量元素,在甲状腺激素合成中起作用,并具有抗氧化特性,表明其在HT管理中的潜在治疗价值.
研究的目的:
- 系统地审查和对随机对照试验 (RCT) 进行元分析.

主要方法:
- 从创立到2023年1月,在多个数据库 (MEDLINE,Embase,CINHAL,Web of Science,Google Scholar,Cochrane CENTRAL) 进行系统的文献搜索.
- 包括35个独特的随机对照试验 (RCT) 涉及元分析.
- 主要结局:没有甲状腺激素替代疗法 (THRT) 的患者的TSH. 二级结局包括甲状腺抗体 (TPOAb,TGAb,TRAb),甲状腺激素,超声检测结果,免疫标志物和不良事件.

Synthesis and Regulation of Thyroid Hormones
4.6K
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
2.8K
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...
