Resumen
Introducción: El trasplante renal es la opción terapéutica que ofrece la mejor expectativa de vida en los pacientes con enfermedad renal crónica. Muchos pacientes sensibilizados permanecen largo tiempo en lista de espera, aumentando su morbi-mortalidad en diálisis.
Objetivos: evaluar el uso de terapia de desensibilización en pacientes con anticuerpos anti HLA Clase II contra su donante vivo relacionado, identificar factores de riesgo temprano de requerimiento de biopsia renal por sospecha de rechazo y evaluar los costos relacionados.
Resultados: Realizamos valoración de terapia de desensibilización a 3 pacientes, con una disminución en los valores de anticuerpos donante específico a menos de 1000 de MFI, con un índice de RIS bajo, por lo que se procedió con el trasplante, sin complicaciones inmediatas y con un seguimiento a 18 meses sin deterioro de función renal.
Conclusiones: La desensibilización previa a trasplante renal permite disminuir el título de anticuerpos donantes específicos preformados y llevar a cabo el trasplante renal, con una buena evolución del paciente y del injerto superior a permanecer en diálisis.
Abstract
Introduction: Renal transplantation is the therapeutic option that offers the best life expectancy in patients with chronic kidney disease. Many sensitized patients remain on the waiting list for a long time, increasing their morbidity-mortality on dialysis.
Objectives: to evaluate the use of desensitization therapy in patients with Class II HLA antibodies against their related living donor, identify early risk factors for renal biopsy requirement for suspected rejection, and assess related costs.
Results: We perform desensitization therapy assessment to 3 patients, with a decrease in specific donor antibody values to less than 1000 MFI, with a low RIS index, so transplantation was carried out, without immediate complications and with a follow-up to 18 months without impaired renal function.
Conclusions: Pre-renal transplant desensitization reduces the titles of preformed specific donor antibodies and performs renal transplantation, with a good evolution of the patient and the graft, superior than remaining on dialysis.
