title: Severe hyperhomocysteinaemia and 5-oxoprolinuria secondary to antiproliferative and antimicrobial drug treatment.
abstract: A hitherto healthy 7-year-old girl underwent antiproliferative and antibiotic treatment owing to the diagnosis of T-cell lymphoma and concomitant bacterial infection. She developed an encephalopathic crisis associated with metabolic acidosis, hyponatraemia and severe hyperhomocysteinaemia and 5-oxoprolinuria. Laboratory tests normalized completely after recovery. Primary defects in glutathione metabolism could be excluded.
