Mental and motor development correlates in patients with end-stage biliary atresia awaiting liver transplantation
Insights
Children with biliary atresia awaiting liver transplants show developmental delays. Early nutritional support and aggressive liver disease management are crucial for optimizing development in these young patients.
Area of Science:
- Pediatrics
- Developmental Psychology
- Hepatology
Background:
- Biliary atresia is a severe liver disease in infants and children.
- End-stage biliary atresia necessitates liver transplantation.
- Developmental outcomes in this population require further investigation.
Purpose of the Study:
- To assess mental and motor development in infants and children with end-stage biliary atresia.
- To identify relationships between developmental status and disease-related variables.
- To inform strategies for optimizing development in this patient group.
Main Methods:
- Bayley Scales of Infant Development and Stanford-Binet Intelligence Scales/Minnesota Child Development Inventory were used.
- Physical growth, liver function (serum bilirubin, albumin), and disease severity were measured.
- Statistical analyses, including multiple regression, were performed.
Main Results:
- Infants showed significantly related mental and motor development to height and weight.
- Infant mental development correlated with serum vitamin E levels.
- Children's development linked to liver function markers (bilirubin, albumin), not growth.
Conclusions:
- Growth and disease indices predict a significant portion of developmental variance in infants.
- Optimizing nutrition and managing liver disease pre-transplant are vital.
- Developmental support is critical for children with biliary atresia.
Abstract:
We measured mental and motor development in 27 infants and 14 children with end-stage biliary atresia who were awaiting liver transplantation, and we measured disease-related variables (physical growth, liver function, and severity and duration of disease) that may relate to development. We then determined the relationship between development and the disease-related variables. Infants were assessed with the Bayley scales, and children were assessed with the Stanford-Binet scales of intelligence and the Minnesota Child Development Inventory. The mean +/- SD mental and motor scores for infants were 79.5 +/- 19.6 and 69.7 +/- 17.6, respectively. The mean +/- SD IQ and motor development scores for children were 76.1 +/- 16.6 and 56.9 +/- 18.1, respectively. For infants, mental and motor development were related significantly to height and weight (r values ranged from .42 to .72). Mental development in infants was also related significantly to serum vitamin E levels (P = .03). Multiple regression analyses combining growth and disease-related indices predicted 70% of the variance in mental and motor development in infants (P = .001). For children, development was related to measures of liver function (ie, to serum bilirubin, r = -.51, P = -.08, and to serum albumin, r = .54, P = .06) but not to growth. Careful nutritional support during infancy and aggressive management of liver disease prior to transplantation may be important in optimizing the development of children with biliary atresia who subsequently undergo liver transplantation.
