The metabolic changes in a patient with succinic semialdehyde dehydrogenase deficiency were investigated following valproate administration using urease pretreatment and gas chromatography-mass spectrometry. A stable isotope dilution technique was used for quantification of urinary 4-hydroxybutyrate. Urinary levels of 4-hydroxybutyrate were 4-fold higher after 1-month valproate therapy. 4,5-Dihydrohexanoate, 2-deoxytetronate and 3-deoxytetronate were also 1.7-2.7-fold higher. The urinary excretions of 4-hydroxybutyrate in valproate non-medicated controls were age dependence and decreased with age. Relationships between 4-hydroxybutyrate excretion and 4-hydroxyvalproate or 5-hydroxyvalproate excretion were observed in valproate medicated controls. It seems that 4-hydroxyvalproate and 5-hydroxyvalproate as well as valproate are involved with increased excretion of 4-hydroxybutyrate following valproate administrations.
