22 In Chronic anemia In Urgent treatment ESA ineffective: hemoglobinopathies/BM failure/ ESA resistanceESA gives risk outweigh benefit: previous or current malignancy, previous strokeIn Urgent treatmentrapid correction of anemia: bleeding/ hemorrhagic shockrapid pre-operative Hb correction
23 Rapid correction of anemia 1. rapid acute hemorrhage without immediate control of bleeding 2. estimated BL > 30–40% of BV (1500–2000 ml) with symptoms of severe BL 3. estimated BL < 25–30% BV without evidence of uncontrolled hemorrhage, if signs of hypovolemia recur despite colloid/crystalloid resuscitation 4. in patients with co-morbid factors, transfusions may be necessary with lesser degrees BLMurphy MF, Wallington TB, Kelsey P et al.

27 Erythropoietin stimulating agents The response to EPO is dose-dependent, but great variationThe response depends on the route (iv. versus sc.) and the frequency of administration.The response may be limited by many factorsStroke, mortality, and hypertension may complicated
31 Darbepoetin alfa structurally different from endogenous erythropoietin Epoetin alfa and beta = endogenous erythropoietin (immunological/biological)N-linked oligosaccharideDarbepoetin alfa structurally different from endogenous erythropoietin- oligosaccharide chains- amino acid sequence rearranged- larger molecular weightClinical significance of different molecular structure is unknownThe terminal half-life of Aranesp® was ~ 3-fold longer than that of Epoetin alfa when administered intravenously.

45 IV. ironPrefer IV route of iron administration in CKD 5HD patients over oral iron with and without concomitantESA treatmentInadequacy of oral iron- Low intestinal absorption of oral iron- Poor patient adherenceAdditional IV iron should not routinely be administered
46 Iron targets Individualized depend on pt status If serum ferritin > 500 ng/mlSerum ferritin is not predictive for iron responseTSAT > 25 is not predictive for iron responseKDOQI AJKD 2006
48 IV Iron therapyCommon approach IV iron treatment in CKD 5HD patients: (1) periodic iron repletion, consisting of a series of IV iron doses administered episodically to replenish iron stores (2) maintenance treatment, smaller doses at regular intervals to maintain iron status in specific limits
49 IV.

51 Current concept: partial correction D-CKD and ND-CKD treated with ESARecommend NOT targeting Hgb levels above 13 g/dL.Trials in predialysis-CKD, suggest thatHb levels near normal range ~ moderate anemiasame in clinical benefit but increased risk of adverse outcomesD-CKD : dialysis dependent CKDND-CKD: non-dialysis dependent CKD
52 FDA: the New FDA Labeling for ESA Individualizing therapy for each ptUsing the lowest possible ESA dose requiredto reduce the need for transfusionsThe new labels recommend reducing the ESA dose when Hb > 10 g/dL in ND-CKD andHb > 11 g/dL in D-CKD patientsDoes not seem to be factually correct, because trials found higher risks in patients randomized to near-normal hemoglobin targets (i.e., >130 g/L and not >110 g/L). Information from clinical trials is not available to inform the selection of a hemoglobin target between 11.5 and 13 g/L.The New FDA Labeling for ESA—Implications for Patients and Providers B J. Manns, M Tonelli.
53 FDA: the New FDA Labeling for ESA For D-CKDInitiate ESA when Hb <10 g/dl.If the Hb level > 11 g/dl, reduce or interrupt the dose of ESA.When initiating or adjusting therapy, monitor Hb levels at least q1wk until stable, then at least q1mo.If pts do not respond adequately over a 12-wk escalation period, increase ESA dose further unlikely to improve response may increase risks.FDA: FDA Drug Safety Communication: Modified Dosing Recommendations to Improve the Safe Use of Erythropoiesis-Stimulating Agents in CKD, 2011.The New FDA Labeling for ESA—Implications for Patients and Providers.
