Androgens for the treatment of anemia in peritoneal dialysis patients

Before the advent of recombinant human erythropoietin (EPO), androgens were used for treatment of anemia in dialysis patients. However, after the availability of recombinant EPO in the 1980s, the use of these substances was abondoned. We have previously reported that androgens have beneficial actions on anemia in selected hemodialysis patients. In the present study we have analyzed the effects of androgen administration on hematologic parameters in peritoneal dialysis patients. We evaluated 9 patients treated for 6 months with nandrolone decanoate (200 mg/week intramuscularly). Hemoglobin and hematocrit values experienced a significant increment with respect to basal values during the study (9.2 +/- 0.7 g/dL and 27.7% +/- 2.3% at basal vs. 11.9 +/- 0.5 g/dL and 35.3% +/- 1.6% at month 6, respectively; P < 0.001). In addition to the effects on the hematologic parameters, androgen administration also had beneficial anabolic actions with a significant increment in the serum concentration of total proteins and albumin (basal, 6.1 +/- 0.3 g/dL and 3.1 +/- 0.4 g/dL vs. 6.7 +/- 0.4 g/dL and 3.8 +/- 0.4 g/dL at month 6, respectively, P < 0.01). The only adverse effect was a rise in the serum concentration of triglycerides (176 +/- 54 mg/dL vs. 144 +/- 53 mg/dL, P < 0.01). In conclusion, androgen administration has beneficial effects on erythropoiesis as well as positive anabolic actions in patients under peritoneal dialysis.
