[The significance of erythropoietin for nephrology]

The analysis of the structure of erythropoietin and the subsequent production of recombinant human erythropoietin opened a new era in the understanding of the pathogenesis and therapy of renal anaemia. From the diagnostic point of view sufficiently accurate radioimmunoassays are currently available to throw new light on the pathogenesis of renal anaemia, and enable pharmacokinetic studies of the recombinant hormone to be carried on. For the first time a causal therapy is available for renal anaemia. The following review summarizes the consequences of these innovations on the different aspects of nephrology.
