ABSTRACT

ElsíndromedeDownpredisponeatrastornosmieloproliferativos. Se estima que del 5 % al 30 % de los neonatos con esta condición desarrollarán mielopoyesis anormal transitoria. El tratamiento no está estandarizado; la exanguinotransfusión y la citarabina podrían ser efectivos. Se describen dos casos de pacientes con síndrome de Down, quienes durante el período neonatal presentaron leucemia mieloide aguda y mielopoyesis anormal transitoria, los tratamientos utilizados y sus desenlaces. Se considera que la sospecha y el diagnóstico temprano de esta entidad son factores determinantes en el pronóstico.


Down syndrome predisposes to haematological disorders. It is estimated that 5-30% of neonates with this condition will develop transient abnormal myelopoiesis. Treatment is not standardized; exchange transfusion and the use of cytarabine could be effective. We present two clinical cases of patients with Down syndrome, who during the neonatal period showed acute myeloid leukemia and transient abnormal myelopoiesis, the treatments used and their outcomes. Suspicion and early diagnosis of this entity are considered determining factors in prognosis.
