Tratamiento de la Infección Urinaria por Candida Albicans

Para cistitis sintomática por Candida albicans, el tratamiento de elección es fluconazol oral 200 mg (3 mg/kg) diarios durante 14 días. 1

Diferenciación Crítica: Candiduria Asintomática vs. Sintomática

La candiduria asintomática generalmente NO requiere tratamiento antifúngico, excepto en pacientes de alto riesgo 1:

  • Pacientes neutropénicos
  • Neonatos de muy bajo peso al nacer
  • Pacientes que se someterán a procedimientos urológicos 1

La eliminación de factores predisponentes (especialmente retiro de catéter urinario) resuelve la candiduria en 40-50% de casos sin necesidad de antifúngicos 2, 3

Algoritmo de Tratamiento Según Localización

Cistitis Sintomática por C. albicans (Susceptible a Fluconazol)

Tratamiento de primera línea:

  • Fluconazol oral 200 mg (3 mg/kg) diarios por 14 días 4, 1, 5
  • Remover catéter urinario si está presente 6, 3

Alternativas para cepas resistentes a fluconazol:

  • Anfotericina B deoxicolato 0.3-0.6 mg/kg/día por 1-7 días 1
  • Flucitosina oral 25 mg/kg cuatro veces al día por 7-10 días 1

Pielonefritis por C. albicans (Susceptible a Fluconazol)

Tratamiento recomendado:

  • Fluconazol 200-400 mg (3-6 mg/kg) diarios por 14 días 4, 1

Para cepas resistentes a fluconazol:

  • Anfotericina B deoxicolato 0.5-0.7 mg/kg/día con o sin flucitosina 25 mg/kg cuatro veces al día por 14 días 1, 7
  • Flucitosina sola 25 mg/kg cuatro veces al día por 14 días 1

Si hay sospecha de candidiasis diseminada asociada, tratar como candidemia 1

Consideraciones Especiales para C. albicans

C. albicans es típicamente susceptible a fluconazol, lo que lo convierte en el agente de elección 4, 7, 8. Esta especie representa aproximadamente 60% de los aislamientos en candiduria 7.

El fluconazol alcanza concentraciones urinarias muy altas, lo que explica su eficacia superior en infecciones del tracto urinario 8, 3.

Errores Críticos a Evitar

NO utilizar equinocandinas para infecciones del tracto urinario bajo por Candida, ya que no alcanzan concentraciones urinarias adecuadas 2, 8, 3. Las equinocandinas pueden tener éxito variable, pero también se han reportado fracasos 3.

NO utilizar irrigación vesical con anfotericina B como tratamiento primario, aunque puede ser útil como terapia adyuvante en casos seleccionados de especies resistentes a fluconazol, especialmente C. glabrata 1.

NO tratar candiduria asintomática de rutina, ya que esto representa colonización en la mayoría de casos 1, 8.

Manejo de Factores Predisponentes

Identificar y corregir factores de riesgo es fundamental 1:

  • Diabetes mellitus descontrolada 7, 8, 9
  • Uso de antibióticos de amplio espectro 8, 9
  • Obstrucción urinaria 7, 8
  • Catéteres urinarios permanentes 7, 8, 9
  • Inmunosupresión 7, 9

Monitoreo y Seguimiento

Evaluar respuesta clínica y considerar urocultivo de seguimiento para confirmar erradicación micológica 4, 3.

En pacientes con factores de riesgo adicionales (neutropenia, inmunosupresión severa), evaluar para candidiasis diseminada 2, 6.

Si hay retención urinaria u obstrucción, la resolución urgente de la obstrucción es prioritaria junto con la terapia antifúngica, ya que la obstrucción impide el éxito del tratamiento antifúngico solo 2.
