Hyperalimentation-induced cholestasis. Increased incidence and severity in premature infants
Insights
Parenteral nutrition can cause cholestatic jaundice in neonates, especially premature infants. Early detection and monitoring for liver dysfunction are crucial in infants receiving this form of nutritional support.
Area of Science:
- Neonatology
- Pediatric Gastroenterology
- Clinical Nutrition
Background:
- Parenteral nutrition (PN) is essential for neonates unable to receive enteral feeding.
- Liver dysfunction, including cholestatic jaundice, is a known complication of PN in infants.
- The incidence and risk factors for PN-associated cholestasis in neonates require further elucidation.
Purpose of the Study:
- To investigate the incidence of liver dysfunction, specifically cholestatic jaundice, in neonates receiving parenteral nutrition.
- To identify factors associated with the development of cholestasis in this vulnerable population.
Main Methods:
- A cohort of 267 neonates receiving parenteral nutrition was retrospectively monitored.
- Data collected included clinical signs of liver dysfunction, degree of prematurity, duration of PN, and protein infusate levels.
- Incidence of cholestatic jaundice and associated factors were analyzed.
Main Results:
- Cholestatic jaundice occurred in a significant proportion of neonates, with higher incidence in more premature infants.
- Severity of jaundice showed an inverse correlation with the degree of prematurity.
- Infants with cholestasis required longer durations of PN and had a higher incidence of sepsis.
Conclusions:
- Neonates receiving parenteral nutrition are at risk for developing cholestatic jaundice, particularly those who are highly premature.
- Prolonged PN and sepsis are associated with cholestasis.
- Close monitoring for liver dysfunction in neonates on PN is strongly recommended.
Abstract:
Two hundren sixty-seven neonates who received parenteral nutrition were monitored for signs of liver dysfunction. Cholestatic jaundice occurred in we infants, with a higher incidence in the more immature infants. There was an inverse correlation between severity of jaundice and the degree of prematurity. Infants with cholestasis remained without gastrointestinal feedings and received parenteral nutrition for periods of time significantly higher than infants without cholestasis. The incidence of this complication did not seem to correlate with the amount of protein infusate (amino acid solution). A higher incidence of sepsis was noted in infants who were affected by cholestasis. Close monitoring for signs of liver dysfunction in all neonates receiving parenteral nutrition is strongly recommended.
