Profilaxis combinada con inmunoglobulina intravenosa y plasmaféresis en pacientes altamente sensibilizados, receptores de trasplante renal o combinado hígado-riñón: experiencia en un centro médico colombiano

Introduction. Kidney transplantation is the best treatment option for patients with terminal chronic kidney disease, regardless of the etiology, making graft survival an important feature, which may be affected by immunological or non-immunological factors. This, added to the increasing number of patients on waiting lists, makes it necessary to define management strategies for these patients that allow better long-term results. Objectives. To determine the clinical, humoral and outcome characteristics in highly sensitized recipients of kidney and simultaneous kidney- liver transplant who received combined prophylaxis with intravenous immunoglobulin and plasmapheresis therapy in a Colombian medical center. Materials and methods. A retrospective, observational, descriptive study was carried out that included the transplanted patients between July 4, 2010 and April 19, 2017. Variables included the etiology of chronic kidney disease, the type of therapy received, and waiting time in days, among others. As outcomes, the presence of rejection, type of rejection, graft loss, complications and death were evaluated. Results. From a total of 25 patients, 100% received intravenous immunoglobulin and 84% plasmapheresis. Twelve percent presented graft rejection, all humoral, and 20% lost the graft. Discussion. Despite the great variety of protocols proposed in the literature, an optimal immunosuppression protocol has not been established for this particular population. The protocol in our small cohort did not have a negative impact on the percentage of post-transplant infections nor in the loss of the renal graft, but it did reduce waiting time; therefore, additional studies are required to confirm the findings in this study. Introducción. El trasplante renal constituye la mejor opción de tratamiento para los pacientes con enfermedad renal crónica terminal. La supervivencia del injerto es de gran importancia y puede ser afectada por factores inmunológicos o no inmunológicos; esto unido al número de pacientes en las listas de espera, hace necesario definir estrategias de manejo que permitan tener mejores resultados a largo plazo. Objetivo. Determinar las características clínicas y humorales, y los de- senlaces en receptores de trasplante renal o combinado hígado-riñón, altamente sensibilizados, que recibieron profilaxis combinada con inmunoglobulina intravenosa y plasmaféresis en el Hospital San Vicente Fundación, en Colombia. Materiales y métodos. Se realizó un estudio
