Erythropoietin therapy, hemoglobin targets, and quality of life in healthy hemodialysis patients: a randomized trial.

ABSTRACT:

Background and objectives

The effects of different hemoglobin targets when using erythropoiesis-stimulating agents on quality of life are somewhat controversial, and predictors of change in quality of life in endstage renal disease have not been well characterized.

Design, setting, participants, & measurements

Five hundred ninety-six incident hemodialysis patients without symptomatic cardiac disease were randomly assigned to hemoglobin targets of 9.5 to 11.5 g/dl or 13.5 to 14.5 g/dl for 96 weeks, using epoetin_alfa as primary therapy. Patients and attending physicians were masked to treatment assignment. Quality of life, a secondary outcome, was prospectively recorded using the Kidney Disease Quality of Life (KDQoL) questionnaire at weeks 0, 24, 36, 48, 60, 72, 84, and 96, with prespecified outcomes being fatigue and quality of social interaction.

Results

The mean age and prior duration of dialysis therapy of the study population were 50.8 and 0.8 yr. Mortality was low, reflecting the relatively healthy group enrolled. Of 20 domains within the KDQoL only the prespecified domain of fatigue showed significant change over time between the two groups. Improvement in fatigue scores in the high-target group ranged from 3.2 to 7.9 over time (P = 0.007) compared with change in the low-target group. Higher body mass index and lower erythropoietin dose at baseline were independent predictors of improvement in multiple KDQoL domains.

Conclusions

In relatively healthy hemodialysis patients, normal hemoglobin targets may have beneficial effects on fatigue. Improvement in multiple domains of quality of life is associated with higher body mass index and lower erythropoietin requirements.

Project description:Background:There is no consensus on intravenous (IV) iron supplement dose, schedule, and serum ferritin target in functional iron deficiency anemia to maintain optimum target levels of iron stores by several guidelines. Objective:To examine the effect of IV iron supplementation to different targets of serum ferritin on erythropoietin dose and inflammatory markers in chronic hemodialysis (HD) patients with functional iron deficiency anemia. Design:A multicenter, randomized, open-label study. Setting:In a developing country, Thailand. Patients:Chronic HD patients with functional iron deficiency anemia. Measurements:Erythropoietin resistance index, high-sensitivity C-reactive protein, and fibroblast growth factor 23. Methods:Two hundred adult chronic HD patients with transferrin saturation less than 30% and serum ferritin of 200 to 400 ng/mL were randomized 1:1 to maintain serum ferritin 200 to 400 ng/mL (low-serum ferritin group, N = 100) or 600 to 700 ng/mL (high-serum ferritin group, N = 100). During a 6-week titration period, participants randomized to the high-serum ferritin group initially received 600 mg IV iron (100 mg every week), while the participants in the low-serum ferritin group did not receive IV iron. During the 6-month follow-up period, the dose of IV iron was adjusted by protocol. Results:The mean dose of IV iron was 108.3 ± 28.2 mg/month in the low-serum ferritin group and 192.3 ± 36.2 mg/month in the high-serum ferritin group. The mean serum ferritin was 367.0 ± 224.9 ng/mL in the low ferritin group and 619.6 ± 265.2 ng/mL in the high ferritin group. The erythropoietin resistance index was significantly decreased in the high-serum ferritin group compared to the low-serum ferritin group after receiving IV iron in the 6-week titration period (mean difference: -113.43 ± 189.14 vs 41.08 ± 207.38 unit/week/g/dL; P < .001) and 3-month follow-up period (mean differences: -88.88 ± 234.43 vs -10.48 ± 217.75 unit/week/g/dL; P = .02). Limitations:Short follow-up period. Conclusion:Maintaining a serum ferritin level of 600 to 700 ng/mL by IV iron administration of approximately 200 mg per month as a maintenance protocol can decrease erythropoietin dose requirements in chronic HD patients with functional iron deficiency anemia. Trials registration:The study was registered with the Thai Clinical Trials Registry TCTR20180903003.
