Measuring biomarkers of acute kidney injury during renal replacement therapy: Wisdom or folly?

Abstract

Early data are now appearing relating to the measurement of biomarkers of acute kidney injury during renal replacement therapy. These data go some way in describing the clearance of these molecules during renal support. Understanding the potential clearance, or otherwise, of these proteins may lead to directing our therapies in the future particularly with regard to cessation of renal support. We describe a recent study which has provided data that may aid in addressing this issue. © 2014 Ostermann and Forni; licensee BioMed Central Ltd.
