Background: In the general population, aging induces changes in body composition, such as sarcopenia or a relative increase in visceral fat, but it remains unclear if similar changes occur in elderly haemodialysis (HD) patients.
Methods: Age-related changes in muscle and fat mass and fat distribution in the thigh and abdomen were cross-sectionally investigated in Japanese HD patients. The thigh muscle area (TMA), thigh intermuscular fat area (IMFA), thigh subcutaneous fat area (TSFA), abdominal muscle area (AMA), abdominal visceral fat area (AVFA) and abdominal subcutaneous fat area (ASFA) were measured by computed tomography in 134 non-diabetic patients between 21 and 82 years on HD.
Background: There is controversy about whether the dietary protein requirement of 1.2 g/kg/d for hemodialysis (HD) patients, in the nutritional guidelines recommended by the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative (NKF-KDOQI), is reasonable.
Methods: A cross-sectional study was conducted in 129 stable HD patients without diabetes (84 men, 45 women) to investigate the association between the protein equivalent of nitrogen appearance normalized by ideal body weight (nPNAibw), an index of protein intake, and skeletal muscle mass or other metabolic consequences.
Background: Muscle wasting is highly prevalent in long-term hemodialysis (HD) patients. Although inflammatory indices have been associated with malnutrition in these patients, the role of inflammation in muscle wasting has not yet been determined.
Methods: The relationship between the inflammatory mediators C-reactive protein (CRP) and interleukin-6 (IL-6) and the muscle mass indices thigh muscle area (TMA), measured by computed tomography, and creatinine (Cr) production, estimated by the Cr kinetic model (Cr-CKM), were investigated in 188 HD patients.
