概括
和维生素D缺乏症在低度症 (HPP) 中很常见. 标准的补充指南有效地纠正这些缺陷在HPP患者没有恶化骨症状.
科学领域:
- 生物化学 生物化学
- 遗传学 是一个遗传学.
- 内分泌学 在内分泌学.
背景情况:
- 低酸性 (HPP) 是一种罕见的遗传疾病,由组织非特异性性酸酶 (TNSALP) 基因的突变引起,导致严重的骨异常.
- 作为TNSALP的辅助因子,而维生素D对骨矿化至关重要,使其在HPP病理生理学中的作用显著.
- 之前的研究表明,和维生素D缺乏症在HPP患者中发生的情况与普通人群相似,但它们在HPP中的目标补充疗效和安全性仍在调查中.
研究的目的:
- 调查和维生素D缺乏症在低酸盐症患者队列中的患病率.
- 评估标准和维生素D补充剂方案的有效性和安全性,以纠正HPP患者的这些缺陷.
- 为了确定标准补充剂是否会影响HPP患者的其他疾病或骨周转标志物.
主要方法:
- 对263名低酸盐症患者的回顾性分析,根据变异分类 (ACMG 3-5,非良性) 和数据完整性进行过.
- 在选定的HPP队列中评估维生素D和缺乏率.
- 在10名缺乏和38名缺乏维生素D的HPP患者中使用既定指南评估补充剂的效果.
主要成果:
- 维生素D缺乏症在73.5%的HPP子队列中被观察到,而缺乏症在27.2%中.
- 补充剂在各自缺乏HPP的患者群体中显著增加了血清和维生素D水平.
- 在补充剂后,关键疾病标志物 (性酸盐,pyrodoxal-5-phosphate) 或骨循环标志物 (酸盐,,PTH,BSAP,肌素,DPd) 没有显著变化.
结论:
- 和维生素D补充的标准指南适用于HPP患者,并且有效.
- 补充剂成功地解决了缺陷,而不会对骨和平衡产生不利影响,也不会加重疾病负担.
- 这支持使用已建立的补充协议来管理低酸性中微量营养素缺乏的情况.

Role of Vitamins in Maintaining Bone Health
3.4K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Essential Minerals for Bone Health
4.1K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Introduction to Electrolytes
10.3K
In humans, electrolytes play a vital role in various physiological processes. Balancing electrolyte levels is essential for normal body functions; their imbalance can be life-threatening. The major electrolytes include sodium, potassium, chloride, calcium, phosphate, and bicarbonate. They are primarily involved in physiological processes, such as nerve signal transmission, membrane trafficking, muscle contraction, buffering body fluids, and balancing water levels in the body.

Bone Disorders
3.7K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Skeleton and Calcium Homeostasis
4.6K
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.

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
