Melas: aproximación diagnóstica y experiencia terapéutica reporte de dos casos. Hospital de San José, Bogotá DC.

Melas syndrome: a diagnostic and therapeutic approach - a report of two cases Hospital de San José, Bogotá DC.

La ocurrencia de encefalopatía, miopatía mitocondrial, acidosis láctica y episodios de strokelike es un raro síndrome clínico que se manifiesta por encefalopatía con convulsiones, acidosis láctica y episodios de strokelike (apoplejía) que constituyen una causa de enfermedad cerebrovascular en el adulto joven. Tiene expresión clínica distinta entre los mismos miembros de una familia y su base fisiopatológica se encuentra en la alteración de la fosforilación oxidativa con la subsecuente depleción de ATP en la célula, secundaria a una mutación en el ADNmt, siendo la 3243 A>G la más frecuente. No se ha establecido un protocolo de tratamiento adecuado para los pacientes con MELAS y lo recomendado está basado en reportes de casos o estudios abiertos no aleatorios. Se debe brindar una terapia apropiada a las comorbilidades encontradas, teniendo en cuenta el potencial de algunos fármacos para exacerbar la enfermedad.
