Burn severity, copper dose, and plasma ceruloplasmin in burned children during total parenteral nutrition.
Copper (Cu) is an essential nutrient with known metabolic roles in wound healing. Ceruloplasmin (CP), the primary Cu-transport protein, responds as an acute-phase reactive protein after trauma. However, for severe burn trauma, this response is absent in the early catabolic phase despite Cu provision. We report data for 14 severely burned children receiving Cu in total parenteral nutrition (TPN-Cu) ranging from 7 to 26 micrograms Cu.kg-1 x day-1. All patients manifested low plasma levels of CP. The reduction in CP reflected burn severity but also appeared to be dependent on the Cu dose. Increasing Cu supplementation to improve CP raises a concern for hepatotoxicity, which is accompanied by an elevation in the plasma nonceruloplasmin Cu (nonCP-Cu). The calculated plasma nonCP-Cu in our series is consistent with a lack of increased risk and suggests that TPN-Cu at the general pediatric guideline of 20 micrograms.kg-1 x day-1 is safe and reasonable for severely burned children. Cu supplementation > 20 micrograms/kg may be beneficial; however, monitoring of both CP and total Cu should continue as standard practice in the management of these patients.
