概括
在全甲状腺切除术后达到最佳的甲状腺激素水平仍然具有挑战性,只有大约三分之一的患者在早期达到甲状腺功能缓和症. 目前的勒沃甲状腺素 (LT4) 剂量策略缺乏一致的有效性,需要进一步研究个性化的方案.
科学领域:
- 内分泌学 在内分泌学.
- 手术瘤学手术瘤学
- 药理学 药理学是指药理学的学科.
背景情况:
- 整体甲状腺切除术需要终身甲状腺素 (LT4) 替代疗法.
- 手术后早期达到最佳甲状腺激素水平往往是困难的.
- 对于早期甲状腺功能减退症最有效的LT4剂量策略,目前还没有达成共识.
研究的目的:
- 在全甲状腺切除术后的首次随访中,系统地审查和元分析患者中达到安甲状腺症的比例.
- 为了比较不同LT4剂量策略的有效性.
主要方法:
- 对涉及2577名患者的11项研究 (2000-2024) 的系统综述和元分析.
- 分析固定剂量,基于体重 (剂量/公斤) 和基于算法的LT4剂量策略.
- 进行元回归和子组分析以确定异质性来源.
主要成果:
- 综合的甲状腺功能减缓率为33.9%,具有显著的异质性 (I2 = 82.68%).
- 没有一个单一的LT4剂量策略始终优于其他 (剂量/公斤:29%;固定的/算法:40%).
- 没有发现轻甲状腺症的显著预测因素;没有基于疾病类型或研究设计的差异.
结论:
- 大约三分之一的患者在甲状腺切除术后获得早期的甲状腺功能减退症,无论使用的LT4剂量策略如何.
- 当前的指导方针建议 (例如,剂量/公斤) 可能不足.
- 需要进一步的研究来制定精细的个性化剂量方案,并确定影响因素.

01:20Synthesis 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...

01:23The 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...

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...

01:15Drug Dosage Regimen: Overview
3.8K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

01:01Dosage Regimen: Fixed Dose
2.0K
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...

01:16Insulin: Dosing Regimen and Adverse Effects
262
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...
