title: Case report: intestinal clearance of calcium and protein in Waldenstrom's macroglobulinemia.
abstract: A 63-year-old man with Waldenstrom's macroglobulinemia had severe steatorrhea, marked protein-losing enteropathy, and excessive endogenous fecal calcium clearance. The malabsorption and protein loss resulted in weight loss and hypoalbuminemia. In contrast, the striking enteric calcium loss was completely compensated by an increase in calcium absorption resulting in a positive calcium balance.
