Neurodevelopmental outcomes of infant intestinal transplant recipients.

Little is known about the impact of intestinal transplantation on development of the infant brain. In this study we report four neurodevelopmental studies on children receiving either liver or intestinal/multivisceral transplants. Our preliminary investigation examined the pretransplant status of 27 infants, who were either liver or intestinal/multivisceral candidates, using the Bayley Scales of Infant Development. A second study examined 23 infants after liver or intestinal/multivisceral transplant. A third study included pre- and posttransplant evaluations on 5 multivisceral infant transplants. In the fourth study, 10 children were tested several years after intestinal/multivisceral transplantation. Some children are able to achieve a normal development. However, even several years posttransplant most children can still experience significant cognitive delays. Children receiving a transplant during infancy may also suffer severe motor delays. Infants undergoing intestinal/multivisceral transplantation show significantly more cognitive delays than those undergoing single-organ liver transplantation. In addition, multivisceral transplanted infants are more likely to continue to be severely developmentally delayed at the time of hospital discharge. With improved survival rates for infant transplants, both cognitive and motor development must be evaluated to determine the need for early intervention. In addition, educating families on the importance of compliance with intervention services outside the hospital is essential to maximize long-term neurodevelopmental outcomes for these infants.
