ABSTRACT

Contexto la procalcitonina (PCT) podría ser útil en la evaluación de la función del injerto renal (IR) en el postrasplante inmediato, ya que sus niveles se incrementan posterior a la elevación de citocinas inflamatorias (IL-6, TNF-ß) durante eventos de disfunción renal. Objetivo determinar la asociación de la PCT sérica con la función del injerto renal en el periodo postrasplante inmediato. Metodología cohorte retrospectiva de septiembre del 2018 a abril del 2019 en la División de Nefrología y Trasplantes, del Centro Médico Nacional de Occidente (CMNO), del Instituto Mexicano del Seguro Social (IMSS). Se incluyeron 62 receptores de trasplante renal de donante vivo (DV) y fallecido (DF) con determinación de PCT antes del séptimo día del TR y el registro de eventos de disfunción temprana del injerto (DTI), comparados con pacientes sin DTI (sDTI). Resultados los receptores con DTI presentaron niveles más altos de PCT (13,90, 3,90, 1,22 ng/mL) comparado con el grupo sin DTI (0,32, 0,31 y 0,22 ng/ml) en los días 1, 3 y 5 respectivamente; p < 0,05. Conclusiones la PCT es un marcador biológico asociado a DTI en el postrasplante renal inmediato.


Background Procalcitonin (PCT) could be useful for evaluation of the renal allograft (RG) in the immediate post-transplant since its levels increase after elevation of the inflammatory cytokines (IL-6, TNF-ß) during events of renal failure. Purpose Our objective was to determine the association of serum PCT with the function of the RG in the immediate post-transplant. Methodology A retrospective cohort from September 2018- April 2019 in the National Western Medical Center of the Mexican Social Security Institute (IMSS), was performed. Sixty-two recipients of living donor (LD) and deceased donor (DD) renal transplant (RT) with PCT evaluation before the seventh days of RT were included; and, events of early renal allograft failure (EAF) were recorded and compared to patients no EAF (nEAF). Results The recipients with EAF presented with higher PCT levels (13.90, 3.90, 1.22 ng/mL) compared to the nEAF group (0.32, 0.31, and 0.22 ng/ml) on days 1, 3, and 5, respectively (p < 0.05). Conclusions The PCT is a biological marker associated with EAF in the immediate post-transplant.
