概括
在接受levothyroxine治疗的甲状腺功能低下患者中,较高的自由甲状腺素水平是必不可少的,以保持足够的自由三甲状腺素. 监测自由甲状腺素和自由三甲状腺素水平对于优化治疗结果至关重要.
科学领域:
- 内分泌学 在内分泌学.
- 甲状腺疾病 甲状腺疾病
背景情况:
- 甲状腺功能低下症需要使用levothyroxine替代疗法.
- 监测甲状腺激素水平对于有效治疗至关重要.
研究的目的:
- 为了研究levothyroxine剂量与自由甲状腺素 (FT4) 水平之间的关系.
- 为了确定治疗患者的FT4升高是否表明过量服用药物或是必要的,以达到最佳的自由三甲基氨酸 (FT3) 水平.
- 为了指导改善Levothyroxine治疗中的监测实践.
主要方法:
- 从1,409名甲状腺功能低下患者 (2021年7月至2024年3月) 3,020次FT4测量的回顾性分析.
- 排除具有甲状腺素受体抗体或服用抗甲状腺药物的患者.
- 使用Elecsys FT4 III免疫试验,比较使用Levothyroxine治疗和未治疗组之间的FT4水平和FT3/FT4比率.
主要成果:
- 接受levothyroxine治疗的患者的FT4水平中位数明显高 (17.9 pmol/L) 比未接受治疗的患者 (16.2 pmol/L).
- 与未接受治疗的患者 (0.28) 相比,接受治疗的患者 (0.24) 的FT3/FT4比率明显较低.
- 增加的勒沃甲状腺激素剂量与更高的FT4水平和更低的FT3/FT4比率相关,在更高剂量时,轻微抑制甲状腺刺激激素.
结论:
- 在接受levothyroxine治疗的甲状腺功能低下患者中,提高FT4水平对于维持足够的FT3很重要.
- 建议对FT4,FT3和它们的比率进行监测,以优化levothyroxine治疗.
- 临床医生应注意,较高的勒沃西剂量可能导致FT4水平超过标准参考范围.

Synthesis and Regulation of Thyroid Hormones
5.1K
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
3.2K
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...

Renal Failure: Dose Adjustments
164
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Rational Dosage Regimen: Maintenance Dose and Loading Dose
4.4K
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...

The Thyroid Gland
4.4K
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...

Insulin: Dosing Regimen and Adverse Effects
265
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...
