概括

早期诊断单碳酸输送物8 (MCT8) 缺乏是非常重要的. 在发育迟缓的婴儿中测试自由T3和自由T3 / T4比率可以改善这种可治疗疾病的结果.

科学领域:

内分泌学在内分泌学.
遗传学是一个遗传学.
儿科儿科儿科

背景情况:

单碳酸转运体-8 (MCT8) 缺乏,或艾伦-赫伦顿-达德利综合征 (AHDS),是一种罕见的X相关疾病,影响甲状腺激素运输.
在SLC16A2基因的致病变体导致T3和T4运输受损,导致中央甲状腺功能低下和外周甲状腺功能过高.
由于正常的TSH水平和不完整的遗传检测,延迟诊断是常见的,阻碍了早期干预.

研究的目的:

突出早期诊断MCT8缺乏的标志物的重要性.
强调更广泛的遗传小组纳入和新生儿查AHDS的潜在好处.

主要方法:

一个5个月大的婴儿被诊断出MCT8缺乏症的案例研究.
甲状腺功能测试显示正常的TSH,低的自由T4和高的自由T3/T4比率.
启动三甲酸 (TRIAC) 治疗并进行监测.

主要成果:

婴儿出现低血压,发育迟缓,甲状腺功能测试异常.
使用TRIAC的治疗导致了一些发育进展,并减少了甲状腺功能障碍,尽管持续存在运动缺陷.
这个案例说明了自由T3和FT3/FT4比率的诊断实用性.

结论:

通过特定的甲状腺激素检测及早发现MCT8缺乏症对于患有不明原因发育迟缓的婴儿至关重要.
扩大基因小组和实施新生儿查SLC16A2变体可以显著改善早期诊断和患者的结果.

Inborn Errors of Metabolism

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...

Cystic Fibrosis: Management

Cystic Fibrosis: Management

Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.
Sinus disease and chronic...
