概括
对晚发佩病 (LOPD) 的新生儿查 (NBS) 揭示了早期的表型和不同的临床表现. 早期酶替代疗法 (ERT) 可能有利于通过NBS识别的选择婴儿,突出需要长期跟踪和明确的治疗指南.
科学领域:
- 遗传学和罕见疾病.
- 溶酶体储存障碍 溶酶体储存障碍
- 新生儿查的进展 新生儿查的进展
背景情况:
- 晚发佩病 (LOPD) 是一种进展性神经肌肉溶酶体疾病.
- 新生儿查 (NBS) 可以更早地发现LOPD,揭示了比以前理解的更广泛的疾病谱.
- 将LOPD与婴儿发病的庞培病 (IOPD) 区分开来,取决于早期心肌病不存在.
研究的目的:
- 系统地审查来自台湾和美国的新生儿查 (NBS) 数据,以发现晚发佩病 (LOPD).
- 分析通过NBS识别的LOPD病例中的临床表现,基因型,生物标志物,治疗方法和后续数据.
- 了解NBS对LOPD诊断和管理的影响.
主要方法:
- 系统的PubMed文献搜索到2026年1月使用关键词:"佩病"",晚发佩病"和"新生儿查".
- 包括通过NBS诊断的LOPD报告的研究;排除非英语文章和仅关于婴儿发病的庞培病的研究.
- 数据提取包括基因型,生物标志物,肌肉成像,酶替代疗法 (ERT) 状态和结果;由于数据异质性而导致叙事合成.
主要成果:
- 在GAA中常见的拼接部位变异c.-32-13 T > G (IVS1) 在台湾不存在,但在美国队列中很常见,通常与较轻的LOPD表型有关.
- 对IVS1和另一种致病性GAA变体的复合异质合体个体显示出不同的表现,有些人经历了高的生物标志物和早期运动征兆.
- 台湾的人口层面数据显示,39例LOPD病例中有21%在1.6个月至3岁之间启动了ERT;美国数据显示,早期启动ERT改善了一些NBS确定的婴儿的生化和运动结果.
结论:
- 新生儿查 (NBS) 扩大了对以前未被识别的LOPD表型的理解.
- 异质的随访协议,缺乏统一的诊断标准,以及有限的长期数据在LOPD管理中带来了挑战.
- 未来的研究应该专注于长期跟踪,详细的表型,并制定更明确的指导方针,以在NBS检测到的LOPD病例中启动ERT.

Lysosomal Hydrolases
4.7K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

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...
