概括
低骨肌量是患有罕见代谢障碍法布里病 (FD) 的儿童常见的早期症状. 这项研究发现,肌肉质量减少,而不仅仅是低BMI,在早期FD患者中很普遍.
科学领域:
- 生物化学 生物化学
- 遗传学 是一个遗传学.
- 儿科 儿科 儿科
背景情况:
- 费布里病 (FD) 是一种罕见的X链代谢疾病,由α-银酸酶A缺乏引起,导致葡萄糖脂积累.
- 低体重和低BMI在FD患者中曾经有过事报告,但早期患病率和潜在原因尚不清楚.
- 这项研究调查了被诊断患有FD的儿童的身体组成和肌肉质量.
研究的目的:
- 为了确定是否体重不足在法布里病的早期阶段是常见的.
- 分析儿科FD患者的身体组成,以确定低BMI的原因.
- 为了评估患有FD的儿童的骨肌肉质量.
主要方法:
- 从2014年7月至2022年12月期间诊断出FD的18名儿童的临床数据的回顾性分析.
- 使用双能X射线吸收计 (DXA) 扫描来评估身体成分.
- 测量包括脂肪质量 (FM),无脂肪质量 (FFM),骨质量,全身肌肉质量和尾骨肌肉质量 (ASM).
主要成果:
- 18名儿童中有16名 (88.9%) 的身高正常,这表明体重不足是低BMI的主要原因.
- 在12名儿童 (66.7%) 中观察到异常的无脂肪质量指数 (FFMI),13名经典表型患者中有10名 (76.9%) 显示肌肉质量减少.
- 与对照组相比,肌肉质量指数,ASM指数和下肢骨肌量指数 (LLSM) 的显著降低.
结论:
- 低骨肌量是患有法布里病的儿童常见的早期症状.
- 这一发现表明,即使在FD的早期阶段,骨肌也受到显著影响.
- 这是第一个在早期儿科FD患者身上检查身体组成和肌肉质量的研究.

Disorders of the Skeletal Muscle
996
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Satellite Stem Cells and Muscular Dystrophy
2.0K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...
