Twenty-one patients developed acute renal failure in association with nontraumatic rhabdomyolysis and myoglobinuria. The illness followed an overdose of ethanol, heroin, or other depressant drug in 18 patients. Lethargy or coma was present in 17 patients and muscle swelling in 11. Evidence of rhabdomyolysis included markedly elevated creatine phosphokinase, myoglobinuria, and aldolase in blood. Initial biochemical findings were similar to those of acute renal failure due to other causes, but the abnormalities were exaggerated. There was a disproportionate rise in serum creatinine concentration in relation to serum urea nitrogen concentration. Profound hyperuricemia was present in most patients. Transient hypercalcemia developed during the diuretic phase in 5 patients. One patient died. We conclude that nontraumatic myoglobinuria with acute renal failure is not infrequent and may occur after an overdose of ethanol or heroin. The disease has good prognosis despite severe hypercatbolism and untreated profound hyperuricemia.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
