OBJECTIVE To report a case of valproic acid overdose treated successfully with high-flux hemodialysis without the addition of charcoal hemoperfusion. CASE SUMMARY A 25-year-old white woman with a history of multiple suicide attempts and schizophrenia presented after ingesting an unknown amount of valproic acid. She became comatose and developed hypotension and lactic acidosis as valproic acid...

INTRODUCTION An epileptic child had been long treated with valproic acid and lamotrigine. After a few years of treatment, he manifested severe clinical signs of hypocalcemia. We retain that valproic acid could have caused such metabolic dysfunction. CASE PRESENTATION We report here the involvement of valproic acid in symptomatic hypocalcemia in an 11-year-old epileptic white patient in treatm...

A patient with valproic acid induced hyperammonaemic encephalopathy is presented. During chronic treatment with valproic acid this patient developed a potentially life-threatening encephalopathy without signs of liver failure. After discontinuing the valproic acid the patient recovered completely. In the case of a patient presenting with hyperammonaemic encephalopathy, the possibility of the us...

The biochemical mechanisms mediating the rapid distribution of valproic acid across placenta are not precisely known. We have characterized valproic acid transport by the human trophoblast using the human choriocarcinoma cell line, BeWo. The uptake of [14C]valproic acid by BeWo cells was found to be saturable and blocked by pre-exposure to the metabolic inhibitors, sodium azide and 2,4-dinitrop...

OBJECTIVE To investigate the relationship between platelet count and serum valproic acid level, age, duration of valproic acid therapy, and polytherapy, and to determine the clinical significance of thrombocytopenia associated with high-dosage valproic acid therapy. DESIGN Cross-sectional study. SETTING Residential unit for neurologically impaired children and paediatric out-patient clinic,...

OBJECTIVE To investigate the effect of valproic acid on plasma levels of risperidone and its active metabolite, 9-hydroxyrisperidone under steady state conditions in 12 schizophrenic patients. METHODS The efficacy and tolerability for the combination treatment of valproic acid and risperidone were examined. RESULTS The addition of valproic acid to risperidone significantly reduced total sco...

A girl with intractable epilepsy who received high dose valproic acid showed bone marrow suppression, which improved after the end of valproic acid treatment and the administration of supportive treatments. Valproic acid markedly suppressed the in vitro colony growth in this patient. It is believed that high dose valproic acid treatment directly suppressed the growth of haematopoietic progenito...

objective(s): t-cell acute lymphoblastic leukemia (t-all) is an aggressive hematologic malignant tumor. administration of chemical compounds influencing apoptosis and t cell development has been discussed as promising novel therapeutic strategies. valproic acid (vpa) as a recently emerged anti-neoplastic histone deacetylase (hdac) inhibitor and pioglitazone (pgz) as a high-affinity peroxisome p...

objective(s): valproic acid (vpa) has proven to be as one of the most promising useful drug with anticancer properties.in this study, we investigate the vpa effects on e-cadherin expression in hela, tc1, mkn45, and hct116 cell lines.  this study assesses the effects of vpa on human papillomavirus e7 expression in hpv positive cell lines. materials and methods: cell lines were treated by2 mmol/l...
