Total parenteral nutrition in the management of acute renal failure.

Malnutrition is frequently present in patients with acute renal failure and may affect morbidity and mortality in this condition. When adequate nourishment cannot be given through the gastrointestinal tract, total parental nutrition with amino acids and hypertonic glucose may have beneficial results. Total parenteral nutrition has been reported to stabilize or reduce serum urea nitrogen, potassium and phosphorus levels, improve wound healing, enhance survival from acute renal failure, and possibly increase the rate of recovery of renal function. The optimal composition of the total parenteral nutrition infusate is unknown. Preliminary results of a double-blind study are reported in which one man received hypertonic glucose alone, two received glucose with essential amino acids (21 g/day), and three received glucose with essential (21 g/day) and nonessential (21 g/day) amino acids. All infusates were isocaloric. No differences were observed in serum urea nitrogen levels, serum urea nitrogen/creatinine ratios or urea appearance rates. Nitrogen balance was negative in all patients. The ratio of essential amino acids/nonessential amino acids were higher and the tyrosine/phenylalanine ratios were lower in plasma in the two patients receiving glucose with essential amino acids. No patient survived the hospitalization. In view of the markedly negative nitrogen balance frequently observed in these and earlier studies, the use of a different composition or quantity of amino acids, a higher energy intake, and anabolic hormones deserve further investigation.

Charcoal-induced lipid reduction in uremia.

Charcoal, in divided oral doses totalling 35 g/day, was administered to six patients with renal insufficiency (creatinine clearance of 0 to 45 ml/min). Significant (P less than 0.01) reductions in serum cholesterol and triglycerides were observed in the three most hyperlipidemic patients. Maximal decreases in charcoal responders, as compared with control values, were for cholesterol (43%, 23.4% and 40.4%) and for triglycerides (76%, 60.3% and 64.3%). None of the patients showed altered concentrations of BUN, serum creatinine, uric acid, or vitamin A. Because of its safety and the profundity of its hypolipidemic action, it is suggested that charcoal may find applicability in the management of azotemic diabetic and nephrotic hyperlipidemia.
