Research output: Contribution to journalArticlepeer-review


A 10-year-old severely disabled Italian boy on long-term treatment with valproic acid presented with tubular proteinuria, generalized aminoaciduria, normoglycemic glucosuria, and phosphate wasting. Since no other explanation for these renal tubular abnormalities was found, the treatment with valproic acid was discontinued. The abnormalities resolved within 5 months after discontinuing this anticonvulsant. We recommend screening patients on long-term anticonvulsant therapy with valproate periodically for renal tubular dysfunction, either via urinalysis or via measurement of urinary lactate/creatinine ratio, if clinical suspicion is high.
