特异性骨骼肌病变构成心力衰竭、慢性阻塞性肺病和2型糖尿病的共同特征,其中其特征在于骨骼肌氧化能力的丧失。有证据表明,在体外和动物研究,铁缺乏症影响骨骼肌功能,主要是在其能量的背景下,通过限制氧化代谢有利于糖酵解和改变碳水化合物和脂肪的分解代谢过程。在这篇综述中,我们描述了骨骼肌能量障碍的可能的分子病理机制,并假设缺铁是一个重要的因素,因果关系与肌肉氧化能力的损失,有助于骨骼肌病患者心力衰竭,慢性阻塞性肺疾病,2型糖尿病。
Specific skeletal myopathy constitutes a common feature of heart failure, chronic obstructive pulmonary disease, and type 2 diabetes mellitus, where it can be characterized by the loss of skeletal muscle oxidative capacity. There is evidence from in vitro and animal studies that iron deficiency affects skeletal muscle functioning mainly in the context of its energetics by limiting oxidative metabolism in favour of glycolysis and by alterations in both carbohydrate and fat catabolic processing. In this review, we depict the possible molecular pathomechanisms of skeletal muscle energetic impairment and postulate iron deficiency as an important factor causally linked to loss of muscle oxidative capacity that contributes to skeletal myopathy seen in patients with heart failure, chronic obstructive pulmonary disease, and type 2 diabetes mellitus.
