- 胃肠病学 胃肠病学
- 外科手术患者管理
背景情况:
- 患有甲状腺功能低下症的患者需要甲状腺激素替代疗法,通常是口服levothyroxine (T4).
- 小肠切除可以改变口服药物的吸收和新陈代谢,包括levothyroxine.
- 现有的指导方针可能无法充分解决小肠切除后的勒沃西替代药物的特定风险.
研究的目的:
- 为了突出显著的甲状腺功能低下症的风险,在小肠切除后的甲状腺功能低下症患者.

- 对潜在的药理动力学和药理动力学变化的分析,这些变化会影响小肠切除后的勒沃西 (T4) 吸收和疗效.
- 关于手术患者甲状腺激素替代疗法的当前临床指南和文献的审查.
主要成果:
- 接受稳定口服levothyroxine (T4) 的甲状腺功能低下症患者在小肠切除后容易出现明显的甲状腺功能低下症.
- 这种风险仍然存在,尽管在术前进行静脉注射 (IV) 补充和早期口服T4恢复.
- 在这种情况下,目前的治疗策略可能无法预防手术后的甲状腺功能低下症.
结论:
- 小肠切除术后的甲状腺功能低下症是接受levothyroxine (T4) 治疗的患者的重大风险.

Synthesis and Regulation of Thyroid Hormones
8.5K
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 Gland
8.2K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.

Histology of the Small Intestine
4.3K
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Hormones and Bone Tissue
4.1K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Factors Influencing Drug Absorption: Disease States and Pharmacology
1.6K
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...
