Chronic hepatic encephalopathy(CHE) is a serious neuropsychiatric disease with altered neurological status and changes in brain metabolites (among others, decrease in brain tCr). If CHE is acquired in childhood these conditions might perturb normal brain development. Our aim was to test whether oral Cr supplementation dampens the neurometabolic changes observed in CHE in a longitudinal model of chronic liver disease in young rats. Using in vivo longitudinal brain 1H and 31P-MRS, we showed rescued tCr levels, enhanced energy metabolism (restoration of ATP), improved antioxidant capacity (increased Asc), positive effect on phospholipid metabolism and smaller increase in Gln (marker of CHE).
