Often underestimated or misunderstood in chronic renal failure (CRF), muscle wasting is nevertheless common and concerns about 50% of dialysis patients. The consequences of this myopathy on quality of life and outcomes of patients are unfavorable, identical to those observed in sarcopenia in elderly subjects with sarcopenia. The similarities between the two situations also concern the symptoms, the underlying muscle damages and the pathogenic mechanisms and may be partly explained by the frequently high age of ESRD patients. Skeletal muscle involvement should be systematically investigated in the IRC patient as in the elderly with sarcopenia to propose as early as possible a treatment of which physical activity and nutritional interventions are the mainstay.
