RESUMEN
Neurotoxicity caused by cefepime may occur predominantly in patients with impaired renal function. A case of a cefepime-induced non-convulsive status epilepticus (NCSE) is presented. A 65-year-old woman suffered a severe NCSE due to cefepime in the presence of acute renal failure, requiring coma induction with sodium thiopental. A serious interaction between valproic acid (VPA) and meropenem was also produced after changing cefepime to meropenem. Continuous veno-venous haemofiltration was employed to improve cefepime clearance, and the patient progressively regained her previous mental condition. In conclusion, the cefepime dose must be adjusted according to renal function in order to avoid toxicity in patients with renal failure. Electroencephalogram should be considered in cases of acute confusional state in patients receiving cefepime, to achieve early detection of NCSE. Continuous renal replacement therapy may be successfully employed in severe cases in order to accelerate cefepime removal. Likewise, meropenem should not be used concomitantly with VPA (AU)
La neurotoxicidad por cefepime puede producirse principalmente en pacientes con insuficiencia renal. Presentamos un caso de status epiléptico no convulsivo producido por cefepime. Una mujer de 65 años con fracaso renal agudo en tratamiento con cefepime sufrió un episodio grave de status epiléptico no convulsivo que requirió inducción de coma barbitúrico con tiopental sódico. Tras el cambio de cefepime a meropenem se produjo también una interacción grave entre meropenem y ácido valproico. Se utilizó hemofiltración venovenosa continua para acelerar el aclaramiento de cefepime y la paciente recuperó progresivamente su situación neurológica previa. En conclusión, la dosis de cefepime debe ser ajustada a la función renal para evitar toxicidad en pacientes con insuficiencia renal. Debería considerarse la utilización del electroencefalograma en casos de estado confusional agudo en pacientes en tratamiento con cefepime para un diagnóstico precoz del status epiléptico no convulsivo. La terapia continua de reemplazo renal puede ser empleada en casos graves para acelerar la eliminación de cefepime. Además el meropenem no debe de utilizarse concomitantemente con el ácido valproico (AU)
