概括
在艾滋病毒和MASLD患者中,塞马格卢提德的使用导致肌肉体积减少,但保持了身体功能. 这表明,尽管体重减轻相关的肌肉变化,肌肉功能仍然可以保持.
科学领域:
- 与代谢功能障碍相关的脂肪性肝病 (MASLD)
- 人类免疫缺陷病毒 (HIV) 研究研究
- 药理干预措施 药理干预措施
背景情况:
- 塞马格卢提德是有效的减肥.
- 减肥往往会导致同时减少肌肉质量,这可能会影响身体功能.
- 了解这些影响在特定人群,如艾滋病毒感染者 (PWH) 中至关重要.
研究的目的:
- 分析塞马格卢提德对艾滋病毒 (PWH) 和MASLD患者肌肉体积和身体功能的影响.
- 评估psoas肌肉体积,脂肪分数和体能指标的变化.
- 为了确定是否semaglutide治疗影响肌肉功能,尽管肌肉体积的损失.
主要方法:
- 关于SLIM LIVER研究 (ACTG A5371) 的二次分析,该研究涉及PWH与MASLD.
- 参与者接受了24周的皮下塞马格卢提德,定位为每周1毫克.
- 通过MRI评估肌肉psoas体积和脂肪分数;通过10次椅子上升和4米步行速度测试测量身体功能.
主要成果:
- 在24周内,肌体积减少了9.3% (P<.001).
- 肌肉脂肪分数没有显著变化 (P = .16).
- 椅子上升时间和步行速度表现出无意义的改善,缓慢步行速度的流行率显著下降 (63%至46%,P = .029).
结论:
- 在PWH中用MASLD治疗塞马格卢提德导致psoas肌肉体积减少.
- 尽管肌肉体积减少,但身体功能 (椅子上升,步行速度) 仍保持不变.
- 这些发现表明,即使有相关的肌肉损失,semaglutide也可能在PWH中与MASLD保持身体功能.

Disorders of the Skeletal Muscle
921
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...

Myasthenia Gravis: Overview and Treatment
1.3K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
