Alcaptonuria - Symptom

Nombres alternativos

Ocronosis alcaptonúrica; ACU; Deficiencia de la oxidasa del ácido homogentísico

Síntomas:

La orina en el pañal de un bebé se puede oscurecer y tornarse casi negra después de varias horas. Sin embargo, muchas personas con esta afección pueden no saber que la padecen hasta mediados de la edad adulta (alrededor de los 40 años) cuando se presentan problemas articulares y de otro tipo.

Los síntomas pueden abarcar:

  • Artritis, especialmente de la columna, que empeora con el tiempo
  • Oscurecimiento de la oreja
  • Puntos oscuros sobre la parte blanca del ojo ( esclerótica) y la córnea

Pruebas y exámenes:

Para verificar si hay presencia de alcaptonuria, se hace un examen de orina ( análisis de orina). Si a la orina se le agrega cloruro férrico, éste hará que la orina se torne de un color negro en pacientes con esta afección.
