AFFIRM may therefore help to guide expectations around potential differences in ESA dose requirements when switching hemodialysis patients from DA to PEG-Epo, although the reported mean maintenance DCR is not intended to predict the dose conversion ratio at the individual patient level. ou toutes les 2 semaines (ou par mois en prdialyse) la dose requise Avant 1 an : non indiqu 11 ans : comme chez l'adulte MIRCERA (potine bta - MPG [mthoxy-polythylne glycol]) 1 injection mensuelle la dose requise Non indiqu .

Administer Mircera either intravenously or subcutaneously in adult patients and only intravenously in pediatric patients. 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. The dose of MIRCERA , given as a single intravenous or subcutaneous injection, should be based on the total weekly ESA dose at the time of conversion. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2022;53(5):333-342. doi: 10.1159/000523947.

Anyone you share the following link with will be able to read this content: Sorry, a shareable link is not currently available for this article. Aranesp (darbepoetin alfa) is indicated for the treatment of anemia due to chronic kidney disease (CKD), including patients on dialysis and patients not on dialysis. Administer Mircera as an intravenous injection at the dose (in micrograms) based on the total weekly ESA dose at the time of conversion (see Table 2). Mircera (methoxy polyethylene glycol-epoetin beta) is an erythropoiesis-stimulating agent (ESA). Eligible patients had received hemodialysis for 12 months and DA for 7 months. Due to the skewed nature of the dosing data, mean weekly ESA doses were reported using geometric means; these were derived by calculating the arithmetic mean of the data transformed on the natural logarithmic scale. Epub 2011 Dec 2. ferrous sulfate, Aranesp, Procrit, Retacrit. The pre-transfusion Hb concentrations were similar for transfusions occurring both pre- and post-switch (Fig. There were 16 transfusion events in the pre-switch period and 48 post-switch, with a total of 34 units transfused pre-switch and 95 units in the post-switch period (Fig. 2. There is limited information published on switching erythropoiesis-stimulating agent (ESA) treatment for anemia associated with chronic kidney disease (CKD) from darbepoetin alfa (DA) to methoxy polyethylene glycol-epoetin beta (PEG-Epo) outside the protocol of interventional clinical studies. ?Ij{JVv:oC*#]}V#$M_T.zC>~] L%lq[Tn`QbWB./@ClVgrk)U-j#(0(D reaction occurs.

Patients included in the analysis were less likely to be diabetic (32% vs. 40%), more likely to be receiving DA at a longer dosing interval (60% vs. 73% at QW; 19% vs. 3% less frequently than Q2W), and received a lower geometric mean weekly dose of DA during the pre-switch EP (24.1 vs. 37.7g). However, healthcare-resource utilization and cost data were not collected in this study, preventing comparison of these variables between the pre-switch and post-switch periods. Please click to see accompanying Aranesp full prescribing information and EPOGEN full prescribing information, including Boxed WARNINGS and Medication Guide. Treatment: Treat to anemia in people with chronic kidney disease. Hemoglobin level and weekly equivalent erythropoiesis-stimulating agent dose during the 14-month observation period.

This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. 4! Regression analysis indicated a non-linear relationship between pre- and post-switch ESA doses; DCR decreased with increasing pre-switch DA dose. There are limitations in generalizing the findings of this study to the broader hemodialysis population. MIRCERA Interactions: May require increased anticoagulation (heparin) during hemodialysis.

In controlled clinical trials of patients with cancer, ESAs increased the risks for death and serious adverse cardiovascular reactions. DA can be administered once a week (QW) or once every 2weeks (Q2W) to hemodialysis patients. Mircera is a prescription medicine used to treat the symptoms of Anemia associated with Chronic Renal Failure. DCR was calculated for patients with Hb and ESA data available in both evaluation periods (EP; Months 1 and 2 were defined as the pre-switch EP, and Months 6 and 7 as the post-switch EP). Dosing patterns, drug costs, and hematologic outcome in anemic patients with chronic kidney disease switching from darbepoetin alfa to epoetin alfa. Horowitz J, Agarwal A, Huang F, Gitlin M, Gandra SR, Cangialose CB. The dose of Mircera, given as a single intravenous or subcutaneous injection, should be based on the Clin Kidney J. The remaining enrolment was at four sites divided between three other countries. Changes in ESA dosing and number of transfusions post-switch may have important health-economic implications. Carrera F, Lok CE, de Francisco A, et al. Mean Hb was 11.5 g/dL in the pre-switch EP and 11.4 g/dL in the post-switch EP. PRCA has also been reported in patients receiving ESAs for anemia related to hepatitis C treatment (an indication for which Aranesp and EPOGEN are not approved).

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). The number of transfusions and units transfused increased approximately threefold from the pre-switch to the post-switch period.
