Today three major nephrology societies -- the American Society of Nephrology (ASN), the European Renal Association - European Dialysis and Transplant Association (ERA-EDTA), and the International Society of Nephrology (ISN) ― signed a declaration of collaboration. The organizations agreed that kidney disease is a global challenge that respects no boundaries or borders. Therefore, all available synergies should be used to fight kidney disease and improve the standard of care for kidney patients worldwide.
