Abstract: (5062 Views)
Serum erythropoietin (EPO) concentration was measured by an enzyme-linked
immunosorbent assay (ELISA) in 31 cases of chronic renal failure (CRF),
including 20 hemodialysis (HD) patients, and compared with that of 31 healthy
normal controls. Each patient served as a self-control comparing his or her
pretreatment level with post-treatment values. There was a significant negative
correlation between serum EPO and serum iron ( SI) concentration in HD patients
(p<0.05) the correlation was more prominent after three months of hemodialysis
(p<0.00l). The mean hemoglobin (Hb) concentration was significantly higher in
patients who underwent HD more than once per week as compared with those who
received HD once a week (p<0.00 1). In addition, patients on three months of HD
had a higher Hb level as compared to those who had received HD for one month
(p<0.001). Moreover, there was also a significant negative correlation between
serum EPO concentration and dialysis adequacy (p<0.05), indicating that the
erythropoietin-hematocrit feedback inhibition mechanism had improved due to
general improvement of the patients' metabolism and possible removal of dialyzable
toxins.
