✦ Synopsis

Erythrocyte 2,3-diphosphoglycerate (2,3-DPG ) and adenosinetriphosphate (ATP) levels were determined in 43 children with chronic renal failure on conservative treatment (CT), and 12 children on regular hemodialysis (HD) immediately before and after a HD session. The results were compared to non-anemic and anemic controls. In spite of anemia, erythrocyte 2,3-DPG in renal failure was similar to non-anemic controls at normal blood pH, but rose during dialysis as a result of alkalosis. In contrast, ATP levels were high already at a normal blood pH. 2,3-DPG correlated with packed cell volume (PCV) in children with renal failure but at lower concentrations compared to controls. Both organic phosphates in the erythrocytes showed a significant correlation with blood pH. The poor increase of 2,3-DPG, in combination with elevated ATP levels, suggests uremia-induced inhibition of 2,3-DPG synthesis.

The anemia associated with renal failure is largely due to inappropriate erythropoietin production. There is also good evidence, however, that substances present in uremic serum can inhibit erythropoiesis, although the exact identity of these substances and the mechanism(s) by which they exert this
