Urinary glycosaminoglycans in patients with progressive myoclonus epilepsy.

Urinary GAGs analysis in Progressive Myoclonus Epilepsy (PME) showed an accumulation of uronic acid in the fraction eluted by 1 M NaCl and 3 M NaCl. As analogous changes were found in other myoclonic and epileptic patients receiving large doses of anticonvulsant drugs, these alterations in the GAG urinary pattern were not considered a primary disturbance of PME.
