Abstract
Chronic renal failure (CRF) is frequently complicated by malnutrition and wasting. The loss of lean body mass in CRF is the result of accele rated protein and amino acid degradation. Both appear to occur via aci dosis-induced, glucocorticoid-dependent processes. In skeletal muscle, acidosis stimulates the activity of the rate-limiting enzyme in branc hed-chain amino acid metabolism, branched-brain ketoacid dehydrogenase (BCKAD). The activation of BCKAD in acidosis is likely to be glucocor ticoid-dependent.
