The unaccomplished mission of reducing mortality in patients on kidney replacement therapy

摘要

Six years ago, a comprehensive review by the EURECA-m working group of the ERA-EDTA thoroughly addressed the drivers of mortality in patients with end-stage kidney disease. Not unexpectedly, the key global driver of early death in these patients was the lack of access to kidney replacement therapy. However, and contrary to the expectations of non-nephrologists, mortality was still high when kidney replacement therapy was provided. This was due to excess cardiovascular and non-cardiovascular mortality, and the need to further characterize correctable risk factors and eventually test the impact of correcting them was emphasized. In this issue of ckj, seven reports address risk factors for death in non-dialysis chronic kidney disease (CKD), dialysis and kidney transplant patients. They characterize irreversible (e.g. sex; age; genetic variants of the KL gene encoding the anti-ageing protein Klotho) and reversible (obesity; mineral and bone disorder parameters; anti-depressant drugs, especially those that increase the QT; amputation; public health investments) factors associated with mortality of CKD patients on or off kidney replacement therapy.
