Ingestion of protein is known to increase urinary calcium excretion. By studying the effect of intravenous amino acid infusion on calcium excretion, the variables of diets and intestinal absorption are avoided. Five patients on total parenteral nutrition with otherwise constant nutrient infusions containing 240 mg of calcium were randomized to two different levels of amino acid infusion. On 1 g/kg ideal body weight amino acid infusion, two patients excreted more than 240 mg of calcium in the… CONTINUE READING
