Requirement of parenteral fat in infants with biliary atresia
Insights
Infants with biliary atresia may develop essential fatty acid (EFA) deficiency during parenteral nutrition (PN). Providing 20% of calories from fat emulsion corrected EFA deficiency and was well-tolerated in these infants.
Area of Science:
- Pediatric Gastroenterology
- Nutritional Science
- Neonatology
Background:
- Biliary atresia (BA) is a serious condition in infants requiring surgical intervention.
- Parenteral nutrition (PN) is often necessary post-surgery for infants with BA.
- Essential fatty acid (EFA) deficiency is a potential complication during PN.
Purpose of the Study:
- To determine the optimal fat emulsion requirement in infants with BA receiving PN.
- To assess the impact of different fat emulsion doses on EFA status.
- To evaluate the safety and efficacy of fat emulsion in this population.
Main Methods:
- Prospective study involving 14 infants with BA undergoing surgery.
- Plasma fatty acid composition was analyzed pre- and post-PN.
- Infants received PN with varying fat emulsion doses: 0%, 10%, or 20% of total calories.
Main Results:
- Essential fatty acid deficiency was evident before surgery and worsened with fat-free PN.
- EFA deficiency improved significantly when fat emulsion provided 20% of total calories.
- No adverse effects on liver function tests or serum lipids were observed with fat emulsion administration.
Conclusions:
- A fat emulsion dose of 20% of total caloric intake is recommended for correcting EFA deficiency in infants with BA on PN.
- This fat intake level is generally well-tolerated and safe in infants with obstructive liver disease.
- Careful clinical and biochemical monitoring remains essential during PN therapy.
Abstract:
In a prospective study on infants with biliary atresia (BA) we measured the composition of the plasma fatty acid to determine the requirement of fat emulsion. In 14 infants who underwent initial operation for treatment of BA, a trend toward essential fatty acid (EFA) deficiency was evident before the surgery. Fourteen infants given parenteral nutrition (PN) after surgery were grouped into three according to the dose of fat emulsion, fat free in 4, 10% of the total calories in 5 and 20% of the total calories in 5. After operation, EFA deficiency gradually progressed when on fat free PN. Improvement in EFA deficiency occurred with the administration of fat which corresponded to 20% of the total caloric intake. During PN including fat emulsion, abnormal changes in liver function tests and serum lipid values due to fat emulsion were nil. Infusion of fat which supplies 20% of the total calories is thus recommended for correction of EFA deficiency and is tolerable in infants with obstructive liver disease. However, clinical and biochemical monitoring should be carefully done.
