“…The survival of erythrocytes in a dialyzed patient is reduced; the phenomenon is, at least in part, connected with the trauma tism caused by the pumps used for the blood flux [11,13]. Concurring factors may be a deficiency of folate lost through the dialyzer [6] and a deficiency of iron due to both blood loss and impaired absorption [2,5], However, K ominami et al [11a] have observed normal serum iron values in a group of dialyzed patients. According to L awson et al [14], a defi cient erythrocyte incorporation of r,9Fe exists.…”

“…According to L awson et al [14], a defi cient erythrocyte incorporation of r,9Fe exists. Transferrin values are con stantly reduced [10,23], Finally, the reduction or absence of erythropoie tin production appears to be of great importance in the genesis of anemia [5],…”

“…The possibility of using the dialysate as a vehicle to remove iron has been suggested by a number of preliminary attempts [2,3,6] utilizing various chelating agents but, whether the iron in parenchy matous organs was susceptible to depletion of the plasma iron pool is uncertain. Our preliminary experiments seem to answer this question in the affirmative [7].…”

“…Zus/itzliche Stfitze ffir diese Bewertung des Erythropoietinmangles in der Pathogenese der renalen Anfimie sind die Ergebnisse frfiherer Untersuchungen, die bei Anwendung des in vivo-Bioassays an der polyzythfimischen Maus bei urfimischen, anfimischen Patienten nur in Ausnahmef~illen erh6hte Serum-Erythropoie-tinspiegel ergaben. [5,7,9,12,19,20,27,28]. Da in der Regel das Ausmal3 der Anfimie mit dem Schweregrad der Azotfimie korreliert ist [9,11], wird angenommen, dab der Abfall der exkretorischen Leistung der Niere begleitet wird von einer entsprechenden Verminderung der inkretorischen Funktion, d.h. auch der Erythropoietinproduktion und -freisetzung.…”

“…Z u einer Verbesserung der Gewebsoxygenierung ffihrt auch die bei Patienten mit renaler An/imie in der Regel zu beobachtende adaptative Steigerung des Herz-Zeit-Volumens [32]. Die Ergebnisse belegen im Obrigen, dab die Korrektur der renalen An~imie durch die Hfimodialysetherapie nicht -wie diskutiert wurde [1,12,20,27] -Folge einer Z u n a h m e der renalen oder extrarenalen E r y t h r o p o i e t i n p r o d u k t i o n ist. In A n b e t r a c h t der von uns an einer G r u p p e anephrischer Patienten e r h o b e n e n Befunde [36] erscheint es fraglich, ob auch bei diesen Patienten im Individualfall eine Regulierbarkeit der Serumerythropoiet i n k o n z e n t r a t i o n fiber den Hfimatokrit im Sinne eines negativen feedback erfolgt.…”
