Rationale and Strategies for Preserving Residual Kidney Function in Dialysis Patients.

Background: Residual kidney function (RKF) conveys a survival benefit among dialysis patients, but the mechanism remains unclear. Improved volume control, clearance of protein-bound and middle molecules, reduced inflammation and preserved erythropoietin and vitamin D production are among the proposed mechanisms. Preservation of RKF requires techniques to measure it accurately to be able to uncover factors that accelerate its loss and interventions that preserve it and ultimately to individualize therapy.

In-Hospital Mortality in Cirrhotic Patients with End-Stage Renal Disease Treated with Hemodialysis Versus Peritoneal Dialysis: A Nationwide Study.

Background: Cirrhotic patients often develop end-stage renal disease (ESRD) requiring renal replacement therapy in the form of hemodialysis (HD) or peritoneal dialysis (PD). Studies comparing the outcomes and difference in in-hospital mortality between these 2 groups, particularly among those with ascites, are sparse. We set our objective to determine the dialysis modality with a better in-hospital survival rate among cirrhotic patients with ESRD (ESRD-cirrhosis).
