概括
在重症监护室 (ICU) 入院时,低的自由甲状腺素 (fT4) 水平与败血症患者的死亡率较高有关. 测量fT4可以改善早期毒症风险评估结果.
科学领域:
- 关键护理医学 关键护理医学
- 内分泌学 在内分泌学.
- 内部医学 内部医学
背景情况:
- 甲状腺疾病综合征 (ESS) 和低三甲状腺素 (T3) 与败血症的死亡率增加有关.
- 在败血症患者中,自由甲状腺素 (fT4) 的预后价值仍然存在争议.
研究的目的:
- 为了评估血清自由甲状腺素 (fT4) 水平在ICU入院和败血症或败血性休克患者的死亡率之间的关联.
- 评估fT4对败血症死亡率的预测性能.
主要方法:
- 对149名患有败血症或败血性休克的成年患者进行了回顾性观察研究.
- 在ICU入院后24小时内测量血清fT4和甲状腺刺激激素 (TSH).
- 分析了28天死亡率和住院死亡率,使用单变量和多变量逻辑回归,以及AUROC用于预测能力.
主要成果:
- 较低的血清fT4水平与28天和住院死亡率的增加显著相关 (p=0.01和p=0.014).
- 在幸存者和非幸存者之间,TSH水平没有显著差异.
- 结合fT4的多变量模型表明,对死亡率的歧视性性能有所改善 (AUROC 0.805-0.799).
结论:
- 在ICU入院时,低fT4水平与败血症患者的死亡率增加独立相关.
- 将ft4纳入多参数模型可能会增强败血症早期风险分层.
- 在资源有限的环境中,fT4测量可能是有价值的,因为其他甲状腺测试是不可用的.

Synthesis and Regulation of Thyroid Hormones
8.6K
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...

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...

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
