There has been much concern about impaired immune function in children receiving infused lipid emulsions. Immunologic studies were carried out on 15 infants maintained on parenteral nutrition with intravenous safflower oil emulsion as part of the infusate. Significant increases in percentage rosette formation, total circulating T-cells, and mitogenesis to phytohemagglutinin and pokeweed mitogen were demonstrated after only 1 wk of lipid infusion. Additional parenteral nutrition did not further increase any immunologic parameter. These results suggest that infused safflower oil emulsion does not adversely alter cellular immune function.
