概括
propionic acidemia (PA) 是一种罕见的代谢障碍. 代谢失补偿事件 (MDEs) 在PA患者中很常见,特别是在幼儿和成年人中,导致死亡率增加并突出未满足的需求.
科学领域:
- 生物化学 生物化学
- 遗传学 是一个遗传学.
- 儿科 儿科 儿科
- 内部医学 内部医学
背景情况:
- propionic acidemia (PA) 是一种影响氨基酸代谢的遗传代谢疾病.
- 胰腺炎的特征是代谢失补偿事件 (MDEs),通常呈现为代谢性酸或超氨血.
- 这些事件意味着代谢期和严重的临床挑战受影响的个体.
研究的目的:
- 描述美国PA患者中MDEs的临床概况和负担.
- 分析MDE的发病率,相关的临床参数和医疗保健资源利用情况.
- 为了识别MDE表现和结果的人口差异.
主要方法:
- 使用TrinetX电子医疗记录数据库 (2015-2022) 的回顾性研究.
- 包括269名被诊断患有PA的患者,从2015年1月起进行索引.
- 评估MDE的发病率,临床特征,触发因素,症状,并发症和死亡率.
主要成果:
- 29.4%的PA患者在住院/急救机构中经历了MDEs;47.6%在任何环境中.
- 在非常年轻的 (0-<2岁) 和成年 (≥18岁) 患者中,MDE的发病率更高.
- 成年人MDE通常涉及代谢性酸症,而儿科MDE通常涉及高氨血症;感染是最常见的触发因素.
结论:
- 与没有 (14.7%) 相比,患有MDEs的PA患者的死亡率较高 (21.5%).
- 患有MDE的患者也呈现出增加的并发症和治疗使用率.
- 这项研究强调了与PA中MDEs相关的显著临床负担和死亡率,表明存在大量未满足的需求.

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...
