患有难以治愈的和感染的儿童可能患有谷氨过氧化酶缺乏症. 补充剂和停止抗发作药物改善了他们的健康状况,这表明,酶活性和神经疾病之间存在联系.
科学领域:
- 生物化学 生物化学
- 儿科神经学 儿科神经学
- 营养科学 营养科学
背景情况:
- 在儿童中,吸收性和复发性感染可能表明潜在的代谢或营养障碍.
- 氨酸过氧化酶 (GPx) 是一种关键的抗氧化酶,其缺乏可以损害细胞防御机制.
- 抗药物虽然对于控制发作是必要的,但有时会与代谢途径产生复杂的相互作用.
研究的目的:
- 调查谷氨过氧化酶缺乏症在儿科患者中具有难以治愈的发作,复发性感染和抗药不耐受性的作用.
- 探索细胞内和血谷过氧化酶活性,水平和临床结果之间的关系.
- 评估替代和停止抗药物的疗效,以管理这些复杂的儿科病例.
主要方法:
- 对四名患有严重神经和传染性症状的儿童进行案例研究分析.
- 生物化学测定测量细胞内和血谷过氧化酶活性.
- 评估全血的度.
- 在治疗干预之前和之后对患者状况的临床监测.
主要成果:
- 四名儿童表现出谷氨过氧化酶缺乏症的证据.
- 两个孩子的细胞内GPx活性较低,血正常,血高GPx.
- 另外两个孩子的细胞内GPx活性低,血GPx低,水平低.
- 在停止抗药物治疗和开始治疗后,观察到临床改善,包括和感染的消失.
结论:
- 氨酸过氧化酶缺乏,可能与状况有关,可能导致敏感儿童难以治愈的和复发性感染.
- 替代和抗药物的谨慎管理可以导致显著的临床改善.
- 这凸显了在儿童管理中考虑营养辅助因子缺乏的重要性.

Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
