E-rosette formation, total T-cells, and lymphocyte transformation in infants receiving intravenous safflower oil
Insights
Infused safflower oil emulsion in infants receiving parenteral nutrition did not impair immune function. Studies showed increased T-cells and immune responses after 1 week of lipid infusion, suggesting safety for pediatric patients.
Area of Science:
- Pediatric Immunology
- Nutritional Science
- Intravenous Lipid Emulsions
Background:
- Concerns exist regarding immune function impairment in children receiving infused lipid emulsions.
- Parenteral nutrition is crucial for infants unable to obtain nutrition orally.
- Assessing the immunologic effects of specific lipid emulsions is vital for pediatric care.
Purpose of the Study:
- To investigate the impact of intravenous safflower oil emulsion on cellular immune function in infants.
- To determine if safflower oil emulsion adversely affects key immunologic parameters.
- To evaluate the safety of safflower oil emulsion in the context of parenteral nutrition.
Main Methods:
- Immunologic studies were conducted on 15 infants receiving parenteral nutrition.
- Safflower oil emulsion was administered intravenously as part of the infusate.
- Immune parameters including rosette formation, T-cell counts, and mitogenesis were measured.
Main Results:
- A significant increase in percentage rosette formation was observed after 1 week of lipid infusion.
- Total circulating T-cells and mitogenesis response to phytohemagglutinin and pokeweed mitogen increased significantly.
- No further increase in immunologic parameters was noted with additional parenteral nutrition.
Conclusions:
- Intravenous safflower oil emulsion, as part of parenteral nutrition, does not appear to adversely affect cellular immune function in infants.
- The findings suggest that safflower oil emulsion is safe for use in pediatric parenteral nutrition.
- Early administration of lipid emulsions may positively influence infant immune responses.
Abstract:
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.
