Section of Gastroenterology, Department of Medicine, Clinical Nurition Research Center, and Department of Pharmacy, University of Chicago, Chicago, Illinois Hypercalciuria and negative calcium balance are potential complications of total parenteral nutrition (TPN). Dietary phosphorus has been observed to have an hypocalciuretic effect. The present study evaluates the effects of administration of increasing intravenous phosphorus (P) loads on urinary calcium excretion in TPN patients. Urinary calcium exceeded daily calcium intake by 50 mg/d when 700 mg/d P was administered, was equal to intake at 1000 mg/d P, and was 30 mg/d less than calcium intake when 1300 mg/d P was given. These findings suggest that TPN-induced hypercalciuria can be attenuated in the short-term by intravenous phosphate. Reevaluation of the phosphorus requirement in patients receiving long-term TPN should be considered. (Journal of Parenteral and Enteral Nutrition 10:188-190, 1986)
