概括
缓释三甲胺 (SRT3) 单疗法治疗甲状腺功能低下症,维持正常的血清三甲胺 (T3) 水平. 然而,在甲状腺功能低下患者中,对甲状腺刺激激素 (TSH) 进行持续调节是不够的.
科学领域:
- 内分泌学 在内分泌学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 甲状腺功能低下症的治疗通常涉及levothyroxine (L-T4) 单疗法.
- 使用L-T4和缓释T3 (SRT3) 的联合治疗可以使T3/T4比率正常化.
- 之前没有任何临床研究研究过SRT3单疗法治疗甲状腺功能低下症.
研究的目的:
- 评估SRT3单疗法在治疗原发性甲状腺功能低下症中的疗效.
- 评估SRT3对血清自由甲状腺素 (fT4),三甲状腺素 (T3) 和甲状腺素 (TSH) 水平的影响.
主要方法:
- 第一部分:对20名甲状腺功能低下患者进行随机试验,比较L-T4,SRT3和L-T3 (0.55μg/kg) 持续4周.
- 第二部分:每天接受L-T4治疗的9名甲状腺功能低下患者转换为每天接受SRT3 (0.55μg/kg).
- 血清fT4,T3和TSH水平每周在两个部分都被测量.
主要成果:
- 单独治疗SRT3显著增加了血清T3水平.
- 在第一部分中,SRT3和L-T3使TSH正常化,而L-T4则没有.
- 在第二部分中,SRT3保持了正常的T3,但到21日,TSH水平上升至正常以上.
结论:
- 在低甲状腺患者中,SRT3单疗可以维持正常的血清T3水平.
- 单独治疗SRT3不足以持续维持正常的血清TSH水平.
- 需要进一步的研究来优化SRT3的剂量和评估其长期影响.

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
2.5K
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...

Myasthenia Gravis: Overview and Treatment
1.1K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Drug Therapy

The advent of drug therapy has profoundly shaped modern mental health care, providing targeted treatments for a range of psychological disorders. Psychotherapeutic drugs, classified into antianxiety, antidepressant, and antipsychotic medications, address symptoms across anxiety disorders, mood disorders, and schizophrenia. While these medications have transformed patient outcomes, they require careful management due to their potential side effects and limitations.

The Thyroid Gland
3.5K
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...

Antidepressant Drugs: MAOIs and Other Agents
185
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
