概括
高剂量的氧巴胺 (OH-Cbl) 在患有巴胺C (Cbl-C) 缺陷的婴儿中显著改善了代谢和神经认知结果. 剂量调整对于这些患者的更好的长期结果至关重要.
科学领域:
- 生物化学 生物化学
- 遗传学 遗传学 是一个
- 神经学 神经学
背景情况:
- 哥巴胺C (Cbl-C) 缺陷是一种导致严重健康问题的代谢障碍.
- 目前用氧巴胺 (OH-Cbl) 治疗的有效性受到不清楚的剂量指南的限制.
研究的目的:
- 评估不同OH-Cbl剂量对早期Cbl-C患者生化,神经认知和视觉结果的影响.
- 在通过新生儿查 (NBS) 诊断的患者中,比较高剂量与低剂量OH-Cbl治疗.
主要方法:
- 在3年内对20名早期Cbl-C患者进行了回顾性分析.
- 患者被分为高剂量 (A组) 和低剂量 (B1和B2组) 的OH-Cbl治疗组.
- 生物化学标志物,神经发育评估和视觉检查进行了评估.
主要成果:
- 与低剂量组相比,高剂量OH-Cbl (A组) 显著改善了同型半氨酸,氨酸和甲基马龙酸水平.
- 组A表现出更好的神经认知结果,特别是在发育系数,听力和言语和表现子表.
- 所有组的黄斑病发病率都很高,这表明OH-Cbl剂量可能不会影响视觉结果.
结论:
- 在被诊断为NBS的Cbl-C患者中,高剂量OH-Cbl治疗导致了卓越的代谢和神经认知改善.
- 最佳的OH-Cbl剂量对于提高Cbl-C缺陷的长期结果至关重要.
- 需要进一步的研究来了解对视力障碍的影响.

592
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

50
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
