1 Introduction Sarcopenia is defined as loss of muscle mass, strength and/or performance that worsens with age. It can arise in association with systemic illnesses, particularly those that invoke an inflammatory process, such as chronic kidney disease (CKD) [1]. The reported prevalence of sarcopenia in CKD has varied markedly, ranging from 3.8% to 98.5% in maintenance dialysis patients, depending on the definitions and diagnostic thresholds used [2-7].
