RESUMEN
Introducción. A pesar de que las nuevas terapias inmunosupresoras han mejorado notablemente la evolución clínica de los trasplantes renales, los rechazos agudo y crónico siguen limitando la sobrevida a largo plazo del injerto. En base a lo anterior, el objetivo de este estudio fue determinar la presencia de anticuerpos séricos contra antígenos de histocompatibilidad (HLA) clase I y clase II en niños con rechazo agudo del injerto renal.
Métodos. Se realizó un estudio clínico prospectivo en pacientes con trasplante renal que presentaron rechazo agudo del injerto. Se les tomó muestra de suero al momento de la biopsia renal, misma que fue utilizada para la detección de anticuerpos contra antígenos HLA de clase I y II por ensayo basado en equipo fluoroanalizador (Luminex) y microperlas cubiertas con antígenos clase I y clase II de One Lambda.
Resultados. De 21 pacientes estudiados, 17 pacientes (81%), fueron diagnosticados con rechazo celular y cuatro (19%) con rechazo agudo mediado por anticuerpos.
El tiempo post-trasplante promedio de presentación del rechazo humoral agudo fue de 18.7 meses y para el rechazo celular de 36.7 meses.
Once pacientes (52.3%) presentaron anticuerpos específicos contra el donador. Los anticuerpos contra antígenos HLA clase I donador específicos se encontraron en seis pacientes, siendo más frecuente el rechazo agudo mediado por anticuerpos (humoral), donde todos los pacientes tuvieron anti HLA clase I con Chi cuadrada (
P =0.004). En cuanto a los anticuerpos inespecíficos, el 95.2% de los pacientes desarrollaron este tipo de anticuerpos.
Conclusiones. El 95% de los niños con rechazo del injerto renal presentan anticuerpos anti HLA, específicos y/o no específicos contra el donador. Los anticuerpos anti HLA donador específicos clase I se presentan con mayor frecuencia en el rechazo humoral.
