概括
皮皮性甲状腺癌 (PTC) 患者的自身免疫甲状腺疾病 (AITD) 与较高的甲状腺蛋白抗体 (TgAb) 水平和较慢的抗体清除有关. 然而,AITD不会对放射性治疗 (RAIT) 的有效性产生负面影响.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 在乳头甲状腺癌 (PTC) 手术后,提升的甲状腺蛋白抗体 (TgAb) 水平往往被误认为是复发.
- 同时自身免疫性甲状腺疾病 (AITD) 对TgAb动态和PTC治疗结果的影响经常被低估.
研究的目的:
- 研究AITD对PTC患者基线TgAb水平的影响.
- 分析放射性治疗 (RAIT) 后TgAb正常化的动力学.
- 评估AITD与持久性结构性疾病风险之间的关联以及PTC中的RAIT疗效.
主要方法:
- 对287名TgAb阳性PTC患者进行了回顾性队列研究,这些患者接受了全甲状腺切除术和RAIT.
- 患者根据术后病理和甲状腺过氧化酶抗体 (TPOAb) 状态被分为非AITD (A0组) 和并发AITD (A1组).
- 组间临床病理学特征,TgAb正常化和RAIT反应的比较.
主要成果:
- 同时的AITD在75.6%的TgAb阳性PTC患者中存在.
- 与A0.0组相比,A1组 (AITD) 的TgAb基线水平较高,RAIT前结构性疾病持续率增加.
- 在A1组,TgAb正常化显著延长,尽管RAIT疗效和总剂量相似.
结论:
- 同时的AITD与TgAb升高,抗体清除延迟以及PTC患者持续性结构性疾病的风险更高有关.
- 在PTC管理中,AITD不会影响放射性治疗 (RAIT) 的整体疗效.
- 了解AITD的双重作用对于准确解释TgAb水平和PTC预后至关重要.

01:20Synthesis 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...

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...

01:29Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
93
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
