[Comment on the article "Elevated neutrophil-lymphocyte ratio and delayed graft function"]

Kidney transplantation is the replacement therapy of choice in patients with end-stage chronic kidney disease; however, complications such as delayed graft function increase the risk of rejection and reduce survival. It has been made a search of biomarkers as accessible, and reproducible low-cost tools that allow to predict risk. Among them, it has been evaluated the neutrophil-lymphocyte index, an inflammatory biomarker associated with ischemia-reperfusion lesion present in these patients. It was made a review to evaluate its predictive usefulness in post-transplant evaluation and follow-up.
