Increased activities of MAOA and MAOB in autopsied brain tissue from cirrhotic patients with hepatic encephalopathy.

Using radioenzymatic assays, activities of MAOA and MAOB were measured in autopsied brain tissue from cirrhotic patients who died in hepatic coma and in material from an equal number of age-matched subjects who were free from hepatic, neurological or psychiatric disorders. Activities of both MAOA and MAOB were significantly increased in frontal cortex and caudate nucleus, two brain regions shown previously to be the site of functional and morphological alterations of astrocytes and increased concentrations of the acid metabolites of dopamine and serotonin. These findings suggest that increased monoamine metabolism and subsequent modifications of monoaminergic synaptic function could contribute to the pathogenesis of hepatic encephalopathy.[1]
