• W2018181892 abstract "Background: The issues surrounding anemia management in patients receiving dialysis therapy are complex and widely debated. Although numerous trials have been published, clinical practice patterns may differ, particularly in the presence of uncertainty about the optimal management of anemia in this setting. Methods: We examined data from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) regarding use of erythropoietic agents (EA), hemoglobin, and ferritin concentrations and transferrin saturation in 8476 prevalent dialysis patients in Australia and New Zealand during the 6 months preceding March 31, 2001. From this cross-sectional survey, we examined the distribution of reported hemoglobin concentration, transferrin saturation, and ferritin concentration. Among hemodialysis patients, other predictors of hemoglobin examined included urea reduction ratio (URR), age, sex, and the presence of comorbidities. Results: In Australia, 87% of dialysis patients received an EA; in contrast, only 42% of New Zealand patients received an EA. Hemoglobin concentrations were significantly higher in Australia, where 16% of reported values were <100 g/L, compared to New Zealand where 37% reported values were <100 g/L. Transferrin saturation and serum ferritin concentrations were significantly correlated, but less strongly among those receiving EA than those not receiving these agents. Both transferrin saturation and serum ferritin were significantly and independently associated with hemoglobin concentration, as were age and sex. The association with ferritin was inverse: higher serum ferritin concentrations were associated with lower hemoglobin concentrations. There was poor agreement (κ = 0.15) between categories of low transferrin saturation (<20%) and low ferritin concentrations (<200 ng/mL). Among the Australian hemodialysis patients, there was no significant variation in Hb between categories where reported URR was ≥65%, whereas the group with a reported URR <65% had a significantly lower hemoglobin concentration. Conclusions: There was a wide variation in reported hemoglobin concentrations in this population. Potential contributing factors include variable patient responsiveness to EA and iron, differing regulations in Australia and New Zealand regarding government subsidy of EA, and the lack of consensus among physicians regarding hemoglobin target values. Although a cross-sectional study cannot directly address the predictive value of iron indices for iron deficiency, it appears likely that transferrin and ferritin have different relationships with hemoglobin, and measurement of both may have greater clinical utility than either parameter alone." @default.
