概括
甲状腺刺激激素 (TSH) 抑制疗法在差异化甲状腺癌患者中显著增加动脉炎症标志物. 这种较高的血管[18F]-氧葡萄糖摄取量表明心血管疾病的潜在风险增加.
科学领域:
- 内分泌学 在内分泌学.
- 核医学是一种核医学.
- 心血管医学 心血管医学
背景情况:
- 血管炎症是动脉样硬化斑块的关键危险因素.
- 甲状腺刺激激素 (TSH) 抑制是差异化甲状腺癌的标准治疗方法.
- 使用[18F]-氧葡萄糖 (FDG) 定子发射断层扫描 (PET) /计算机断层扫描 (CT) 评估动脉炎症是一种经过验证的方法.
研究的目的:
- 研究TSH抑制治疗对血管壁炎症的影响.
- 评估在经过TSH抑制的分化甲状腺癌患者的动脉[18F]-FDG吸收.
- 为了比较TSH抑制患者和euthyroid对照患者之间的动脉炎症标志物.
主要方法:
- 追溯病例控制研究,涉及40名特异化甲状腺癌患者的TSH抑制和25名甲状腺控制.
- 进行了[18F]-FDG PET/CT扫描,以测量大动脉 (心脏动脉,大动脉) 中的标记物吸收.
- 摄入量以目标与背景比率 (TBRs) 量化,以体重正常化,并根据血液池活动进行校正.
主要成果:
- 治疗TSH抑制的患者在多个动脉段中显著增加了动脉[18F]-FDG吸收,而非甲状腺控制组 (p < 0.001).
- 综合动脉血管的平均TBRmax值在TSH抑制组为1.7 ± 0.2,对照组为1.3 ± 0.1.
- 在持续的TSH抑制后平均1.9年的随访后,在一小组患者中没有观察到动脉[18F]-FDG吸收的显著变化.
结论:
- TSH抑制疗法与血管[18F]-FDG吸收增加有关,这表明动脉炎症增加.
- 接受TSH抑制的患者可能面临心血管疾病的风险增加.
- 抑制TSH的持续时间没有显著影响观察到的动脉炎症增加.

Synthesis and Regulation of Thyroid Hormones
4.1K
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
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...

Psychoneuroimmunology: Cardiovascular Disease
23
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
