OBJECTIVES: Children with liver disease have increased risk of long-term cognitive deficits. We differentiated between the effects of chronic liver disease from that associated with transplantation by recruiting children with cholestatic liver disease with and without transplantation.

METHODS: Psychometric measures and magnetic resonance spectroscopy were obtained for 3 groups of children: stable liver disease (SLD) without transplantation; cholestatic liver disease (CLD) from birth with transplantation; and individuals healthy to 18 months of age, prior to transplantation for acute liver failure (ALF).

RESULTS: Cognitive outcomes between children with different disease histories were significantly associated with the duration of liver disease but not the effects of transplantation, including that of immune suppression. Lower intellectual ability was most frequently observed in the CLD group, whereas all of the ALF group scored within the normal range. Myo-inositol and glutamate/glutamine concentrations in cortex were significantly associated with disease duration across the cohort. Neuro-metabolite profiles in SLD were consistent with subclinical encephalopathy. Impaired growth in early childhood was associated with later cognitive performance.

CONCLUSION: Children with prolonged liver disease had the poorest cognitive outcomes despite successful transplantation, suggesting that prolonged cholestasis before transplantation adversely impacts neurodevelopment, and reinforces the need for timely interventions.
