概括
原发性偏甲状腺症 (PHPT) 扰乱了代谢,受影响的患者表现出更高的FGF23和1-25OH) 2维生素D水平. 手术治疗使这些调节剂正常化,PHPT中的低酸盐水平表明临床结果更差.
科学领域:
- 内分泌学和新陈代谢学
- 腎臟病學 (nephrology) 是一種醫學.
- 骨生物学 骨生物学 骨生物学
背景情况:
- 副甲状腺激素 (PTH) 是和平衡的关键调节者.
- 纤维细胞生长因子23 (FGF23) 和1,25-二氧维生素D (1-25(OH) 2D) 也在酸盐调节中起着至关重要的作用.
- 一种特定的FGF23基因变异 (c.716 C>T) 与酸盐消耗和结石有关.
研究的目的:
- 在患有原发性副甲状腺功能障碍症 (PHPT) 的患者中研究酸盐代谢.
- 评估PHPT对骨和脏健康的影响.
- 探索FGF23基因变异与临床表现的关联.
主要方法:
- 追溯分析比较339名PHPT患者与503名历史队列的对照.
- 在手术后两年,对51名PHPT患者的酸盐代谢重新评估.
- 在患者和对照中对FGF23 c.716 C>T变体进行基因型定型.
主要成果:
- 与对照组相比,PHPT患者表现出血清,PTH,性酸酶,CTx和尿液的升高,血清酸盐,25OH-VitaminD和TmPO4/GFR的降低.
- 在PHPT患者中观察到更高的FGF23水平. 在患有结石的患者中,716 T 基因组更为频繁.
- 手术后,PHPT患者的1-25(OH) 2D和FGF23.3降低. 血清酸盐较低的人 (<2.8 mg/dL) ,PTH,1-25(OH) 2D,尿路和结石的患病率较高.
结论:
- 酸盐代谢调节器在PHPT中失调,并在手术后恢复正常.
- 在PHPT患者中血清酸盐的低水平与更严重的生物化学和临床表型有关,包括增加结石风险.
- 在PHPT的背景下,FGF23基因变异可能导致结石病.

The Parathyroid Glands
1.8K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Roles of Electrolytes: Calcium and Phosphate
148
Calcium and phosphate are essential electrolytes in the human body, with calcium being the most abundant mineral. Around 99% of the body's calcium is stored in the skeleton and teeth, forming a crystal lattice of mineral salts in combination with phosphates. Calcium plays crucial roles in various bodily functions such as blood clotting, neurotransmitter release, muscle tone maintenance, and nervous and muscle tissue excitability.

Hormones and Bone Tissue
2.6K
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...

Skeleton and Calcium Homeostasis
4.4K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Bone Remodeling
38.1K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Synthesis and Functions of Calcitonin
1.5K
Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...
