概括
在 pegvaliase 治疗中患有基尿症 (PKU) 的成年人可以自由饮食,保持营养状况并改善饮食行为. 一些微量营养素摄入量下降,但整体健康标志物保持稳定.
科学领域:
- 代谢障碍 代谢障碍 代谢障碍
- 营养科学 营养科学
- 药理学 药理学是指药理学的学科.
背景情况:
- 基尿症 (PKU) 是一种遗传性疾病,需要限制氨酸 (Phe) 的饮食.
- 佩格瓦利酶使得患有PKU的成年人能够通过降低血液Phe水平来消耗不受限制的饮食.
- 有限的数据存在的营养状况和饮食后的饮食过渡后的饮食行为在PKU患者 pegvaliase.
研究的目的:
- 评估早期治疗PKU的成年人的营养状况和饮食行为的变化,在开始佩格瓦里酶并过渡到无限制饮食后.
- 评估人类学,饮食摄入量,营养标志物,骨矿物质密度,身体组成,休息能量消耗和饮食行为.
主要方法:
- 这是一项为期15个月的前性纵向研究.
- 参与者是早期治疗PKU的成年人,在佩格瓦里酶启动之前接受了限制Phe的饮食.
- 从基线到第15个月对营养状况和饮食行为的评估变化.
主要成果:
- 完整蛋白质摄入量在响应者和部分响应者中显著增加.
- 大多数维生素,矿物质和必需脂肪酸水平保持正常,尽管微量营养素摄入量随着医疗食品消费减少而减少.
- 受访者报告说,食物享受增加,食物恐惧症减少,不受控制的饮食和情绪性饮食.
结论:
- 患有PKU的成年人过渡到不受限制的二酶饮食通常保持了足够的营养状况.
- 受访者在饮食行为上显著改善,包括减少与食物相关的心理痛苦.
- 需要进一步研究更大的样本大小和更长的随访时间来证实这些发现.

Inborn Errors of Metabolism

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...

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...
