The regression analysis that examined the relationship between mean weekly ESA doses in the two evaluation periods indicated that the DCR is not linear; a significant (P=0.008) quadratic term was observed in the regression analysis, indicating that the predicted DCR decreased at higher pre-switch doses of DA (Fig. 2001;38:80312. 5) shows that most transfusions occurred in the first 4months post-switch.

No difference in conversion dosage could be determined between patients who were epoetin sensitive (<200 units/kg per week) or resistant (>200 units/kg per week, P = NS). Further exploration of the relationship between DA and PEG-Epo doses using the BlandAltman method [10], which circumvents the limitations of the regression method in this type of investigation, indicated that the variability in the dose differences increased as doses increased, while the level of concordance decreased with increasing ESA dose. In particular, the likelihood of a transfusion during the post-switch period was significantly higher in patients with a dose ratio below 1 at switch. When initiating or adjusting therapy, monitor hemoglobin levels at least weekly until stable, then monitor at least monthly.

Macdougall IC. In controlled clinical trials, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and the risk of deep venous thrombosis (DVT) in patients undergoing orthopedic procedures. Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events [see Boxed Warning and Clinical Studies (14)]. The WHO has set the daily-defined dose (DDD) for epoetin beta and darbepoetin at 1000 U and 4.5 g respectively, which gives a conversion factor of 222:1 . A BlandAltman analysis [10] was also performed to assess the agreement between ESA doses in the evaluation periods. The aims of the Aranesp Efficiency Relative to Mircera (AFFIRM) study were primarily to estimate the maintenance dose conversion ratio (DCR) of PEG-Epo to DA in a population of European hemodialysis patients switched from DA to PEG-Epo and with comparable mean hemoglobin (Hb) in the pre- and post-switch periods, and secondarily to investigate In the absence of PRCA, follow dosing recommendations for management of patients with an insufficient response to MIRCERA, Cases of PRCA and of severe anemia, with or without other cytopenias that arise following the development of neutralizing antibodies to erythropoietin have been reported in the postmarketing setting in patients treated with MIRCERA, PRCA has also been reported in patients receiving ESAs for anemia related to hepatitis C treatment (an indication for which MIRCERA, If severe anemia and low reticulocyte count develop during treatment with MIRCERA, Serious allergic reactions, including anaphylactic reactions, angioedema, bronchospasm, tachycardia, pruritus, skin rash and urticaria have been reported in patients treated with MIRCERA, Blistering and skin exfoliation reactions including Erythema multiforme and Stevens-Johnson Syndrome (SJS)/Toxic Epidermal Necrolysis (TEN), have been reported in patients treated with ESAs (including MIRCERA, Patients may require adjustments in their dialysis prescription after initiation of MIRCERA, Most frequent adverse reactions ( 5%) in adult patients with CKD treated with MIRCERA. Eschbach JW, Adamson JW. The study sample comprised adult patients (age 18years) with CKD who received maintenance hemodialysis between January 2008 and August 2011 and whose ESA treatment was switched from IV DA to IV PEG-Epo. An additional analysis was performed to explore the effect of transfusions on the DCR, by exclusion of patients with a transfusion within 90days prior to or during either EP from the analysis. In recent years, the trend has been to use higher doses of epoetin alfa (eg, 60,000 U once per week), recognizing that MDS RBC precursors may have relative intrinsic resistance to EPO.

Regardless of possible differences in their clinical characteristics it should be borne in mind that patients were not selected for inclusion in the DCR analysis on the basis of their fulfilling any clinical, Hb or ESA dose requirements: all patients who had Hb measurements in both EPs, a DA dose in the pre-switch EP and a PEG-Epo dose in the post-switch EP were eligible for inclusion.

There are significant negative consequences associated with increased transfusion requirement in dialysis patients, including production of sensitizing anti-human leukocyte antigen (HLA) antibodies which, despite advances in immunosuppressant therapy [13], may impair or prevent transplantation in patients otherwise eligible for receipt of a kidney graft. J Manag Care Pharm. Although the reasons for transfusion were not recorded, the pre-transfusion Hb concentrations within 14days prior to transfusion remained similar for transfusions occurring both pre- and post-switch. Following administration, remove the needle from the injection site and then release the plunger to allow the needle guard to move up until the entire needle is covered. 2012;59:44451.

You may also report negative side effects of prescription drugs to the Food and Drug Administration (FDA). Epoetin beta and methoxy polyethylene glycol may increase tumor growth or decrease survival time in people with certain types of cancer. Cases of PRCA and of severe anemia, with or without other cytopenias that arise following the development of neutralizing antibodies to erythropoietin have been reported in patients treated with Aranesp or EPOGEN. This suggests that the decision to transfuse was consistent with respect to Hb over the observation period (Fig. Slider with three articles shown per slide.

Over the last 25years, several originator and biosimilar ESAs have been introduced for the management of CKD anemia, starting with the first generation short-acting recombinant erythropoietin agents (epoetin alfa and beta) and latterly with two longer-acting molecules, darbepoetin alfa (DA) and methoxy polyethylene glycol-epoetin beta (PEG-Epo), which combine a significantly increased half-life and lower binding affinity for the EPO receptor, allowing them to stimulate erythropoiesis for longer periods and to be administered less frequently [5, 6]. randomized patients to darbepoetin or epoetin beta once weekly after the patients had been treated with epoetin beta three times weekly. Conversion from Another ESA: dosed once monthly or once every two weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion (2.2). Geometric mean weekly PEG-Epo dose at Month 1 post-switch was 26.7g (95% CI 24.4, 29.3), rising to 29g (95% CI 26.2, 32.2) by Month 7 post-switch.
