概括
甲状腺功能,特别是治疗前较高的三甲状腺素 (FT3) 水平,预测在接受免疫抑制疗法 (IST) 的严重无性贫血 (SAA) 患者中,治疗反应更好. 这一发现为管理SAA结果提供了有价值的见解.
科学领域:
- 血液学 血液学 血液学
- 内分泌学 在内分泌学.
- 内部医学 内部医学
背景情况:
- 严重无塑性贫血 (SAA) 是一种危及生命的疾病,需要有效的治疗策略.
- 免疫抑制疗法 (IST) 是SAA的标准治疗方法,但预测治疗反应仍然具有挑战性.
- 甲状腺功能异常在严重疾病中很常见,可能会影响SAA的结果.
研究的目的:
- 调查甲状腺功能的预测价值,特别是自由三甲状腺素 (FT3) 水平,在接受IST的SAA患者中.
- 确定与SAA患者改善治疗反应和生存相关的因素.
主要方法:
- 分析了在2015年2月至2020年6月期间接受IST治疗的149名SAA患者的队列.
- 在134名没有先前存在甲状腺疾病的患者中进行了甲状腺功能测试.
- 响应率,整体存活率和无故障存活率在FT3水平和其他临床因素方面进行了评估.
主要成果:
- 在134名评估患者中,有89名患者 (66.4%) 呈现出异常的甲状腺激素水平,主要是低三甲状腺素 (T3).
- 治疗前FT3水平较高 (>5 pmol/L) 的患者在IST后3个月和6个月显示出显著更高的反应率 (分别为54.5%与35.4%和67.3%与46.9%).
- 较短的疾病持续时间 (≤56天) 和在6个月内获得反应是有利的整体生存和无衰竭生存的独立预测因素.
结论:
- 预处理FT3水平是SAA严重程度的有价值指标,可以预测治疗对IST的反应.
- 更高的FT3水平与更好的反应率有关,这表明甲状腺功能监测在SAA管理中可能发挥作用.
- 优化IST,考虑到疾病持续时间和使用的特定抗胆小细胞球蛋白 (ATG) 等因素,对于改善患者的治疗结果至关重要.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Synthesis and Regulation of Thyroid Hormones
4.6K
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...
