概括
对皮肤T细胞淋巴瘤 (CTCL) 的贝克萨罗 (BXT) 治疗可以导致中央甲状腺功能低下症. 这一案例凸显了需要高剂量的勒沃甲状腺素 (LT4) 和甲状腺素 (LT3) 来控制这种副作用.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 贝克萨罗 (BXT) 是一种合成的视网,用于治疗皮肤T细胞淋巴瘤 (CTCL).
- 已知BXT通过抑制TSH分泌和改变甲状腺激素代谢来引起中央甲状腺功能低下症.
- 有限的数据存在于BXT诱导的中央甲状腺功能低下症中最佳的甲状腺激素替代剂量.
研究的目的:
- 在接受BCT治疗CTCL的患者中报告中央甲状腺功能低下病例.
- 描述该患者甲状腺激素水平正常化所需的levothyroxine (LT4) 和liothyronine (LT3) 剂量.
- 为了强调可能需要高剂量的LT4/LT3联合治疗.
主要方法:
- 一名41岁的CTCL男性患者接受了BXT的治疗.
- 患者在BXT启动后一个月内发展出中央甲状腺功能低下症.
- 甲状腺激素水平受到监测,LT4剂量在15个月内升级,并添加LT3补充剂.
主要成果:
- 患者需要明显高于基于体重的LT4剂量 (约2.8倍) 和补充的LT3 (每天15微克).
- 甲状腺激素水平 (自由T4和总T3) 在每天600微克的LT4和15微克的LT3治疗方案下正常化.
- 这表明需要大量的LT4/LT3组合剂量来管理BXT诱导的中央甲状腺功能低下症.
结论:
- 由BXT诱导的中央甲状腺功能低下症可能需要积极的甲状腺激素替代疗法.
- 在受影响的患者中,可能需要高剂量的组合LT4和LT3来实现类甲状腺症.
- 需要进一步的研究,以建立标准化剂量指南来管理BXT诱导的中央甲状腺功能低下症.

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...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers
162
Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...

Oral Hypoglycemic Agents: Biguanides and Glitazones
196
Biguanides, particularly metformin (Glucophage), are insulin sensitizers that enhance glucose uptake, thereby reducing insulin resistance. Unlike sulfonylureas, metformin doesn't prompt insulin secretion, which helps to curb hypoglycemia risk. Metformin is beneficial in treating conditions like polycystic ovary syndrome due to its insulin-resistance reduction capability. The drug's primary action involves curtailing hepatic gluconeogenesis, a significant contributor to high blood...

Functions of Thyroid Hormones
2.7K
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...

Treatment for Pulmonary Arterial Hypertension: Endothelin Receptor Antagonists
159
Endothelins (ETs) are potent vasoactive peptides critical in the human body's various physiological and pathological processes. One of the most promising therapeutic strategies for treating pulmonary arterial hypertension (PAH) involves counteracting the effects of these endothelins using a class of drugs known as endothelin receptor antagonists.
ETs are synthesized through a complex sequence of enzymatic steps, primarily involving an enzyme referred to as endothelin-converting enzyme...
