Trace metal and essential fatty acid deficiency during total parenteral nutrition. 1978

D M McCarthy, and R J May, and M Maher, and M F Brennan

While deficiences of trace metals and essential fatty acids are rare in humans fed orally, the widespread use of total parenteral nutrition (TPN) has increased the likelihood of encountering these deficiences. A 14-year-old boy, with total villous atrophy of the small intestine, suffered from severe malnutrition and was placed on a conventional TPN regimen. Although not immediately recognized, he rapidly developed deficiencies of zinc, copper and essential fatty acids. Careful monitoring of the course of the illness and the responses to sequential treatments with zinc, lipid, and copper given intravenously allowed examination of the effects of the deficiencies on skin, intestine, liver, and hemopoietic systems and helped to establish normal requirements for the metals. The progress of the illness suggested that patients with intestinal malabsorption may be especially at risk of developing some of these lesser known complications of TPN.

D010288	Parenteral Nutrition	The administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously).

D010289	Parenteral Nutrition, Total	The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.
