Therapeutic challenges in the management of osmotic demyelination syndrome: A case report of a favorable outcome from a tertiary center.
Overview
abstract
RATIONALE: There is an increasing and compelling need for early recognition of features of osmotic demyelination syndrome (ODS), and a further attempt at correcting this even where presentation is late. PATIENT CONCERNS: A 49-year-old male admitted into the emergency department with a complaint of lethargy and severe hyponatremia, with subsequent ODS supervening on initial attempts at correction. DIAGNOSIS: Rapid rise in serum sodium concentration (121 mmol/L in 8 hours from a nadir of 101 mmol/L), concomitant deterioration in patient's conscious level support the diagnosis of ODS. INTERVENTION: Concomitant administration of 5% dextrose water with desmopressin with a therapeutic objective of gradual relowering of serum sodium concentration. OUTCOMES: Significant improvement in patients' conscious level and motor function with the commencement of sodium relowering therapy. The patient was eventually discharged home. LESSONS: Regardless of the temporal profile of neurologic sequelae following ODS due to hyponatremia, its worthwhile attempting initial sodium relowering with dextrose 5% and desmopressin and then monitoring of biochemical and neurologic markers.
