概括
孕期特定的甲状腺参考间隔可能导致亚临床甲状腺功能低下症的过度诊断. 根据这项研究,自由T3 (FT3) 测量在怀孕期间诊断甲状腺疾病的价值有限.
科学领域:
- 生殖内分泌学和新陈代谢.
- 临床诊断和实验室医学.
背景情况:
- 甲状腺生理在怀孕期间经历了显著的变化,需要怀孕特定的参考间隔来准确诊断.
- 然而,这些专业间隔与标准非怀孕间隔的临床实用性和优越性仍未得到证实.
- 预设数据为比较诊断准确性提供了有价值的基线.
研究的目的:
- 为了评估甲状腺疾病的患病率,使用怀孕期间的怀孕特异和非怀孕参考间隔.
- 为了将这些患病率与怀孕前的数据进行比较.
- 评估在孕妇中自由T3 (FT3) 测量的诊断贡献.
主要方法:
- 在鹿特丹进行了一项基于人口的前性队列研究 (Generation R Next).
- 评估甲状腺疾病患病率使用怀孕期间的怀孕特定和非怀孕参考间隔.
- 与怀孕前期的非怀孕参考间隔进行比较;在甲状腺和甲状腺受影响的参与者中分析了FT3水平.
主要成果:
- 这项研究包括1,058名孕前妇女和2,084名怀孕期间妇女.
- 孕期特定的间隔显示出较高的亚临床甲状腺功能低下 (3.6%) 与非孕 (1.5%),较低的亚临床甲状腺功能高 (1.5%) 与非孕 (11.1%).
- FT3测试可以重新分类14.3%的孕妇亚临床甲状腺功能障碍病例.
结论:
- 这项研究是首次将甲状腺疾病患病率的怀孕与非怀孕参考间隔与怀孕前数据进行比较.
- 孕期特定的参考间隔可能导致亚临床甲状腺功能低下症的过度诊断.
- 在怀孕期间诊断甲状腺功能障碍时,FT3测量似乎具有有限的附加价值.

Synthesis and Regulation of Thyroid Hormones
8.4K
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...

Regression Toward the Mean
7.2K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Functions of Thyroid Hormones
6.0K
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...

Therapeutic Drug Monitoring: Affecting Factors
289
Therapeutic Drug Monitoring (TDM) is the clinical practice of measuring specific drug levels in a patient's blood or body tissues to manage and optimize therapy. TDM is crucial for drugs with narrow therapeutic windows, like warfarin and phenytoin, where incorrect doses can lead to treatment failure or severe side effects. This monitoring ensures the dosage administered is within a safe and effective range. The factors affecting therapeutic drug monitoring include:Patient-Specific Factors:a.
