High calorie infusion-induced hepatic impairments in infants
Insights
Infants receiving long-term high calorie infusion may develop hepatic impairments. These liver dysfunctions present in three distinct types, but the exact cause remains unknown.
Area of Science:
- Pediatric Medicine
- Hepatology
- Clinical Nutrition
Background:
- Long-term high calorie infusion is a critical nutritional support for surgical infants.
- Sporadic reports suggest potential hepatic complications associated with this intensive therapy.
Observation:
- This study investigated 18 surgical infants experiencing hepatic impairments during high calorie infusion at Juntendo University Hospital.
- Liver function tests were monitored sequentially to classify the observed hepatic dysfunctions.
Findings:
- Three types of hepatic dysfunction were identified: Type I (transient elevated transaminase), Type II (elevated alkaline phosphatase and bilirubin), and Type III (marked elevation in alkaline phosphatase, bilirubin, and transaminase).
- The specific etiology linking high calorie infusion to these hepatic impairments in infants is currently unknown.
Implications:
- Understanding these distinct patterns of liver dysfunction is crucial for monitoring infants on long-term parenteral nutrition.
- Further research is needed to elucidate the mechanisms behind high calorie infusion-induced hepatotoxicity in pediatric patients.
- This classification may aid in early detection and management strategies for liver complications in vulnerable infant populations.
Abstract:
Hepatic impairments have been reported sporadically in infants receiving long-term high calorie infusion. Some characteristic hepatic impairments induced with high calorie infusion at the Juntendo University Hospital, Tokyo, are studied in 18 surgical infants, with discussion of the possible etiology of this complication in the context of high calorie infusion. The hepatic dysfunctions were classified into 3 types by sequential liver function determinations: Type I with a transient and slightly elevated serum transaminase without elevation of alkaline phosphatase; Type II, an elevation of alkaline phosphatase and total and direct bilirubin without elevation of serum transaminase; Type III, a marked and prolonged elevation of aklaline phosphatase, total and direct bilirubin, and serum transaminase. The etiology of these hepatic impairments during high calorie infusion is unknown.
