Growth evaluation in infants with neonatal cholestasis

Area of Science:

• Pediatric Gastroenterology
• Neonatal Medicine
• Growth and Development

Background:

• Chronic childhood liver diseases frequently lead to undernutrition and growth failure.
• Growth parameters in infants diagnosed with neonatal cholestasis are not well-documented.

Purpose of the Study:

• To assess the nutritional status and growth patterns in infants experiencing intrahepatic cholestasis and extrahepatic cholestasis.

Main Methods:

• A retrospective review of 144 infants with neonatal cholestasis from 1980-2003.
• Patients were categorized into intrahepatic (Group 1) and extrahepatic (Group 2) cholestasis groups.
• Weight-by-age and height-by-age Z-scores were calculated at four distinct growth stages within the first year of life.

Main Results:

• Both groups exhibited weight-by-age Z-score declines, with Group 2 showing a significant deficit from the second stage onwards.
• Height-by-age Z-scores also decreased in both groups, with Group 2 experiencing a more pronounced deficit from the third stage.
• Significant differences in both weight and height Z-scores between Group 1 and Group 2 emerged by the third and fourth growth stages.

Conclusions:

• Weight and height deficits become statistically significant from the third measurement onwards, with extrahepatic cholestasis presenting the most substantial growth impairment.
• Evidence suggests the onset of weight and height deficits in the extrahepatic group occurs between the first and second evaluation stages.
• These findings underscore the critical need for early nutritional and growth monitoring in infants with neonatal cholestasis, especially those with extrahepatic forms.
