概括
患有基尿症 (PKU) 的成年人骨矿物质密度 (BMD) 比普通人群低,尽管大多数仍在预期范围之内. 不到10%的人低于年龄适当的值,这表明需要进一步研究促成因素.
科学领域:
- 代谢障碍 代谢障碍 代谢障碍
- 骨健康 骨健康 骨健康
- 营养科学 营养科学
背景情况:
- 基尿症 (PKU) 管理需要终身饮食氨 (Phe) 限制和专门的医疗食品.
- 以前的研究表明,Phe的长期限制与PKU群体的骨矿物质密度 (BMD) 降低之间存在潜在的联系.
- 需要进行元分析,以专门调查患有PKU的成年人骨硬化.
研究的目的:
- 进行元分析以评估患有基尿症 (PKU) 的成年人骨矿物质密度 (BMD).
- 为了确定汇总的平均 BMD Z-score 和该人群中低 BMD 的患病率.
- 根据研究发表十年,血液Phe控制和性别来探索BMD潜在的亚组差异.
主要方法:
- 系统性文献综述研究报告的BMD结果在PKU在Phe-限制饮食的成年人.
- 来自10项涉及4097人研究的BMD Z-score的元分析.
- 使用苏格兰大学间指南网络检查清单进行偏见风险评估.
主要成果:
- 与年龄相匹配的对照人群相比,患有PKU的成年人表现出统计学上显著较低的多个骨的BMD Z-score平均值,但仍保持在-2.0以上.
- 估计的BMD Z-score ≤ -2.0的患病率为8%,< -1.0为42%.
- 小组分析受到小样本规模的限制,这阻碍了最终的解释.
结论:
- 患有PKU的成年人通常比非PKU个体的BMDZ分数更低,但大多数人属于预期的年龄相关范围.
- 显著的比例 (8%) 的BMD Z-分数低于-2.0.
- 需要进行进一步的研究,以确定影响PKU BMD 的特定人群特征.

Inborn Errors of Metabolism
145
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Bone Disorders
3.4K
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...

Overview of Protein Metabolism
848
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

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.

Essential Minerals for Bone Health
3.8K
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...
