Púrpura trombocitopénica trombótica - Treatment

Nombres alternativos

PTT ADAMTS13

Tratamiento:

Se utiliza el intercambio de plasma (plasmaféresis más infusión de plasma donado) para remover los anticuerpos que están afectando la coagulación de la sangre y también reponer la enzima faltante.

  • Primero, se le sacará la sangre como si usted estuviera donándola.
  • La porción de plasma de la sangre se pasa a través de un separador celular. Se guarda la porción restante de la sangre.
  • Se le agrega plasma y la sangre se le retorna a usted a través de una transfusión.

Este tratamiento se repite diariamente hasta que los exámenes de sangre muestran mejoría.

Las personas que no responden a este tratamiento o cuya afección a menudo reaparece posiblemente necesiten:

  • Someterse a una cirugía para extirparles el bazo.
  • Recibir medicamentos para inhibir el sistema inmunitario, como corticosteroides o rituximab.

Pronóstico:

El intercambio de plasma ha mejorado enormemente el pronóstico de esta enfermedad y la mayoría de los pacientes ahora se recupera por completo. Sin embargo, algunas personas mueren a causa de esta enfermedad, en especial si no se detecta inmediatamente. En las personas que no se recuperan, esta afección puede volverse prolongada ( crónica).

Posibles complicaciones:

Cuándo contactar a un profesional médico:

Consulte con el médico si tiene cualquier sangrado inexplicable.
