ABSTRACT
PURPOSE:
This study was undertaken to examine whether differences exist in the hemoglobin variability according to the types of erythropoiesis stimulating agent (ESA) in hemodialysis (HD) patients.METHODS:
Clinical data were retrospectively analyzed from 72 patients on maintenance hemodialysis who were using darbepoetin alfa (n=27), epoetin beta (n=27), and epoetin alpha (n=18). As parameters of hemoglobin variability, hemoglobin cycling, the variance of hemoglobin and the SD/mean of hemoglobin were analyzed. Hemoglobin cycling was defined as the presence of cycles with an amplitude >1.5 g/dL and lasting more than 2 months.RESULTS:
Hemoglobin cycling was present in 53 (73.6%) out of 72 HD patients. Hemoglobin cycling in patients receiving darbepoetin alfa had greater frequency (1.63+/-0.93 vs. 1.00+/-0.88 times/year, p<0.05), amplitude (2.88+/-1.48 vs. 1.88+/-1.60 g/dL, p<0.05), and velocity (1.21+/-0.74 vs. 0.73+/-0.66 g/dL/month, p<0.05) than that in patients receiving epoetin beta. The variance of hemoglobin in patients receiving epoetin beta (0.79+/-0.53 g/dL) was smaller than that in patients receiving darbepoetin alfa (1.29+/-0.70 g/dL, p<0.05) and epoetin alfa (1.08+/-0.52 g/dL, p<0.05). Also, the ratio of SD/mean of hemoglobin in patients receiving epoetin beta (8.20+/-2.59%) was lower than that in patients receiving darbepoetin alfa (10.81+/-2.10%, p<0.05) and epoetin alfa (10.30+/-2.10%, p<0.05).CONCLUSION:
Hemoglobin variability is differential according to various ESAs, and it may be less with epoetin beta compared with darbepoetin alpha and epoetin alpha.
