When his mentor, Dr.
Belding H. Scribner, challenged Dr. Eschbach, at the time a young nephrology researcher at the
University of Washington, to find a way to correct the anemia in kidney dialysis patients, Dr. Eschbach accepted the challenge. Working with a hematologist, Dr. John W. Adamson, Eschbach looked at various forms of
renal failure and the role a natural hormone,
erythropoietin, had in preventing
anemia. By studying the urine of sheep and other animals in the 1970s, the two scientists helped establish that
erythropoietin did stimulate the bone marrow to produce red blood cells. In the 1980s, Dr. Eschbach helped lead a clinical trial at the
Northwest Kidney Centers studying whether an artificial
erythropoietin hormone,
Epogen, manufactured by
Amgen, could replace or supplement the naturally occurring hormone. The trial was successful, and its results were published in The
New England Journal of Medicine in 1987: Administering artificial erythropoietin did reverse anemia in kidney patients. His research helped to inform and lead to the
Food and Drug Administration's 1989 approval of the replacement hormone
Epogen.
Epogen and its derivative
Erythropoietin Stimulating Agents remain in use throughout the world. == Affiliations ==
