Motor delays remain post-liver transplant in children

Posted on

Children who undergo liver transplantation are at risk of motor delays both before and after liver transplant (LT), according to a study. The severity of liver disease and growth delays may impact motor development.

In this retrospective review, 33 children <6 years old with cholestatic liver disease, including diagnoses of biliary atresia (70%), Alagille syndrome (21%), and others (9%), were assessed before and 1 year following post-isolated LT.

There was a risk of motor delay in >75% of children pre-LT, while post-LT, 52% of children scored ≥1 SD below the mean gross motor quotient (GMQ) compared with 22% fine motor quotient (FMQ).

There was an increased risk of motor delay on GMQ post-LT in patients who were delayed or at-risk pre-LT.

Longer time on the waitlist correlated with lower FMQ post-LT.

GMQ post-LT and height z-scores pre-LT and post-LT were positively correlated.

The authors said the results of this study highlight the need for ongoing rehabilitation before and after LT.
