Intravenous linoleic acid supplementation in children with cystic fibrosis
Insights
Intralipid infusions significantly improved growth in children with cystic fibrosis (CF) compared to glucose infusions over one year. This highlights the importance of essential fatty acids in CF nutrition management.
Area of Science:
- Pediatric Nutrition
- Metabolic Disorders
- Cystic Fibrosis Pathophysiology
Background:
- Cystic Fibrosis (CF) is a genetic disorder affecting multiple organs, often leading to malnutrition and growth deficits.
- Nutritional status is a critical factor in the health outcomes and quality of life for individuals with CF.
Purpose of the Study:
- To investigate the impact of Intralipid (fat emulsion) versus 10% glucose on growth parameters in children with CF.
- To assess the role of essential fatty acids in the nutritional management of CF.
Main Methods:
- A double-blind, randomized controlled trial involving ten children with CF, paired and treated every other week for one year.
- Infusions of Intralipid or 10% glucose were administered, with height and weight gains monitored.
Main Results:
- Both groups showed greater improvement in height and weight compared to the previous year, with statistically significant gains in the Intralipid group.
- Cumulative data analysis revealed substantial improvement for the Intralipid group (23 points) versus a decline for the glucose group (-2 points; P < .02).
Conclusions:
- Intralipid supplementation appears beneficial for improving growth in children with CF.
- Routine monitoring of plasma linoleic acid levels and supplementation when low is recommended for all children with CF.
Abstract:
Ten children with CF in matched pairs were infused with either Intralipid or with 10% glucose on a double blind basis every other week for one year. Although statistically there was significantly greater gain in height and weight in the study year compared to the previous year only for the test group, both groups improved more than expected. Cumulative data analysis showed greater improvement for the Intralipid group (23 of a possible 45 points) compared to the glucose group (-2 points; P less than .02). This study indicates the need to better define the role of nutrition in the pathophysiology of CF. Meanwhile, it is recommended that all children with CF have plasma linoleic acid levels measured at least once yearly, and if levels are low, appropriate supplements should be given.
