概括

系统性初级卡尼缺乏症 (SPCD) 如果不及早发现,可能会导致严重的神经损伤. 这一案例凸显了对标准化新生儿查 (NBS) 和及时诊断的需要,以防止基底腺损伤等并发症.

科学领域:

生物化学生物化学
遗传学是一个遗传学.
神经学神经学

背景情况:

系统性初级卡尼缺乏症 (SPCD) 是一种罕见的代谢障碍,影响脂肪酸氧化.
在SPCD中能量生产受损可能导致低血糖症,脑病变和突然死亡.
目前针对SPCD的新生儿查 (NBS) 协议缺乏标准化,有可能错过诊断.

研究的目的:

报告NBS错过的SPCD病例,导致严重的神经系统后续.
强调早期诊断和SPCD管理的重要性.
倡导对SPCD进行标准化的NBS标准.

主要方法:

一个1岁9个月大的女孩的病例报告,临床表现表明脂肪酸代谢障碍.
诊断工作包括生物化学测试 (血清卡尼丁水平,葡萄糖,氨) 和遗传分析 (SLC22A5突变).
使用神经成像 (MRI) 来评估大脑参与,并监测治疗反应.

主要成果:

患者呈现出缺血性低血糖症,高血和心肌缩,尽管NBS结果正常.
确诊的SPCD与同卵性SLC22A5突变和临界低的肉蛋白水平.
开发了基底腺损伤和 dystonia,需要ECMO和L-DOPA治疗,部分恢复.

结论:

基底腺损伤是SPCD的严重并发症,即使在最初正常的NBS的情况下也是如此.
在怀疑脂肪酸代谢障碍时,迅速补充L-卡尼丁和早期测量是至关重要的.
标准化的NBS协议与定义的卡尼丁切断值对于早期SPCD检测和预防神经损伤至关重要.

关键词:

对于L-DOPA来说,这是一个很好的方法.迪斯托尼亚 (Dystonia) 是一种精神疾病.缺血性低血糖症 (hypoketoic hypoglycemia) 是一种低血糖症.代谢性脑病变是一种代谢性脑病变.系统性初级卡尼缺乏症

Parkinson's Disease: Overview

342

Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Lysosomal Hydrolases

3.7K

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,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
