[Urinary erythropoietin excretion: an unknown cause of anemia during nephrotic syndrome].
BACKGROUND
Nephrotic syndrome (NS) is characterized by an excessive urinary protein excretion.


METHODS
A woman, followed-up for NS, present progressive anemia, with no simple explanation. Plasma EPO is low with significant urinary EPO excretion. Treatment with EPO corrects hemoglobin level.


CONCLUSIONS
EPO deficiency due to excessive urinary excretion is an underestimated cause of anemia during NS.
