Pontine and extrapontine osmotic myelinolysis after the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) associated with fluoxetine: case report

Abstract: -Osmotic demyelination syndrome (ODS) may be precipitated by aggressive correction of a hypo or hyper-osmolar states. We describe the case of a 53-year-old woman that was started on fluoxetine 20 mg/day for depression and nine days later was found to have fluoxetine-induced syndrome of inappropriate secretion of antidiuretic hormone. After hyponatremia correction the mental status of the patient gradually improved, but subsequently she had intermittent difficulty in speaking, naming objects, memory deficits an… Show more

“…We found 54 cases (63% female, median age 45 years, interquartile range 45-58 years) of osmotic demyelination syndrome published since 1997: 45 individual case reports and three case series including a total of nine patients (72,129,130,131,132,133,134,135,136,137,138,139,140,141,142,143,144,145,146,147,148,149,150,151,152,153,154,155,156,157,158,159,160,161,162,163,164,165,166,167,168,169,170,171,172,173,174,175). In 96% (52/54), the diagnosis of osmotic demyelination syndrome was based on magnetic...…”

“…Other causes of edema could be heart or hepatic failure; nevertheless, there were no physical or complementary data to support these possibilities. Additional hypotheses included adverse effects of fluoxetine, as the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) 15 and/or paradoxal weight gain 16 . Although a rapid loss of weight was observed following the fluoxetine interruption, the patient did not show hyponatremia or hypokalemia.…”

“…Existem relatos de hiponatremia com todos os ISRS, entre os quais se incluem o citalopram [15][16][17][18][19] , o escitalopram 14,[20][21][22][23] , a fluoxetina [24][25][26] , a paroxetina 12,13,27,28 e a sertralina [29][30][31][32][33] . A hiponatremia pode surgir em 0,5% a 32% dos utilizadores de ISRS 10,34 .…”

“…A hiponatremia sintomática aguda desenvolve-se em menos de 48 horas e, quando o Na + sérico é mais baixo que 125 mEq/L, predominam os sintomas neurológicos, devido ao desenvolvimento de edema cerebral. Quando a hiponatremia se desenvolve rapidamente, o risco das complicações de edema cerebral é superior ao risco de desmielinização osmótica associada à correção demasiado rápida do Na + sérico, e o tratamento deve começar de imediato, com o objetivo de elevar o Na + sérico em 1,5 a 2 mEq/L/hora até a melhoria dos sintomas ou até o Na + sérico atingir um nível seguro (superior a 118 a 120 mEq/L) 5,24 . O nível de sódio não deve aumentar mais que 12 mEq/L nas primeiras 24 horas e mais do que 18 mEq/L nas primeiras 48 horas, para evitar a desmielinização osmótica.…”
