The association between the use of erythropoietin and urea or creatinine clearance was studied in two populations on continuous peritoneal dialysis (CPD) residing either at an altitude of 1600 m (n = 194) or at sea level (n = 108). Among peritoneal and total KT/V urea and creatinine clearance (CCr) indices, only total CCr was lower in the high altitude group receiving erythropoietin than in the corresponding group not receiving erythropoietin (68.0 +/- 34.9 vs 82.9 +/- 40.9 L/1.73 m2 weekly, p < 0.01). However, 24-hour urine volume and urinary KT/V urea and CCr were consistently lower in the groups receiving erythropoietin than in those not receiving erythropoietin. Total weekly KT/V urea < or = 1.70 and CCr < or = 52 L/1.73 m2 were considered indicators of inadequate CPD. Although the percent of patients receiving erythropoietin did not differ overall between groups with adequate and those with inadequate CPD, a trend towards more frequent use of erythropoietin was found in the sea level group with inadequate CCr versus the group with adequate CCr (28.2% vs 16.9%, p = 0.084). In CPD decreased renal function is associated with more frequent use of erythropoietin. Whether inadequate total urea or creatinine clearance is also associated with more frequent erythropoietin use requires further study.
