Major advances in the treatment of ANCA associated-renal vasculitides, IGA nephropathy and renal autosomal dominant polycystic disease were published within the past year. There is neither clear benefit of early initiation of renal replacement therapy in the intensive care unit nor with the use of chloride-poor solutions to prevent kidney failure. Maintenance parenteral iron supplementation in hemodialysis patients is neither associated with infectious nor cardiovascular risks. Cognitive decline may be more associated with hemodialysis than peritoneal dialysis. In transplantation, the persistence of complement-binding donor-specific antibodies after treatment is predictor of graft loss. Tocilizumab is a promising treatment for chronic antibody-mediated rejection.
