Insights
Children with liver diseases often experience neurodevelopmental deficits, impacting cognitive, behavioral, and motor skills. Early identification of risk factors is crucial for improving long-term outcomes in these vulnerable children.
Area of Science:
- Pediatric Hepatology
- Neurodevelopmental Pediatrics
- Systematic Review Methodology
Background:
- Liver diseases in children can significantly impact neurological development.
- Increasing survival rates in children with liver diseases highlight the need to understand long-term neurodevelopmental outcomes.
Purpose of the Study:
- To systematically review and synthesize the literature on the neurodevelopmental outcomes of children with liver diseases.
- To identify the prevalence and nature of neurodevelopmental deficits in this population.
Main Methods:
- A systematic literature search was conducted across PubMed, Cochrane Library, and PsycINFO following PRISMA guidelines.
- Studies published from 2000 onwards, focusing on term-born children with liver diseases and their neurodevelopmental outcomes, were included.
- A narrative synthesis approach was employed to analyze the selected studies.
Main Results:
- Over two-thirds of studies indicated neurodevelopmental deficits in children with liver diseases, affecting cognitive, behavioral, and motor domains.
- Children post-liver transplantation (LTx) showed higher rates of impaired outcomes (82%) compared to those with native livers (67%).
- Motor development was impaired in 82% of studies for both groups, and 42% of post-LTx children required special education.
Conclusions:
- Neurodevelopmental deficits are prevalent in children with liver diseases, encompassing all developmental areas.
- Limited knowledge exists regarding risk factors and long-term follow-up, necessitating further research.
- Early identification of predictors and risk factors is essential for developing effective intervention strategies to improve long-term neurodevelopmental health.
Objective:
The aim of the study was to determine the neurodevelopmental outcomes of children with liver diseases based on a systematical review of the literature.
Method:
A literature search according to the PRISMA statement was conducted using predefined search terms in PubMed, Cochrane Library, and PsycINFO. The inclusion criterion was studies published from 2000 onwards that reported on the neurodevelopmental outcomes of term-born children with liver diseases. A narrative synthesis was done to appraise the studies.
Results:
Twenty-five studies were included (1913 children), 19 of which described children after liver transplantation (LTx; 1372 children). Sixty-seven percentage of the studies on children with liver diseases who survived with their native livers showed low-average or abnormal scores on specific subscales of cognitive and behavioral measures. In studies on children after LTx, this was 82%. After LTx, 83% of studies demonstrated impaired outcomes on behavior, whereas 42% of children received special education. Motor development was impaired in 82% of studies in children with native liver and after LTx.
Limitations:
Studies were heterogenic because of sample sizes, etiology of liver disease and type of assessment tools used.
Conclusions:
More than two-third of included studies showed neurodevelopmental deficits in children with liver diseases, affecting all neurodevelopmental areas. Knowledge on risk factors for impaired neurodevelopment is limited and lack of long-term follow-up is worrying, especially considering the increasing survival rates, resulting in more at-risk patients. Studying early predictors and risk factors of abnormal developmental trajectories of children with liver diseases is indicated to assess strategies to improve their long-term neurodevelopmental outcomes.
