However, the relationship between the pre- and post-switch ESA doses during the two evaluation periods was non-linear. 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. Mircera solution for injection in pre-filled syringe Months 7 to 1 constituted the pre-switch period, with switch defined as the date of first administration of PEG-Epo, and Months +1 to +7 constituted the post-switch period. Decreases in dose can occur more frequently. Nephrol Dial Transplant. DA can be administered once a week (QW) or once every 2weeks (Q2W) to hemodialysis patients. Concerning RBC transfusions, 36 patients received a transfusion; 7 were transfused in the pre-switch period only, 4 received a transfusion both pre- and post-switch, and 25 had a transfusion in the post-switch period only. doi: 10.1053/ajkd.2001.27699. If the hemoglobin rises rapidly (e.g., more than 1 g/dL in any 2-week period), reduce the dose of MIRCERA. Individualize dosing and use the lowest dose of MIRCERA. Values are means (arithmetic for hemoglobin, geometric for dose) with 95% confidence intervals.

Article Conversion from Epoetin alfa or Darbepoetin alfa to Mircera in Pediatric Patients with CKD Treated with Hemodialysis Administer Mircera intravenously once every 4 weeks to pediatric patients (ages 5 to 17 years) whose hemoglobin level has been stabilized by treatment with an ESA. Aranesp (darbepoetin alfa) and EPOGEN (epoetin alfa) are contraindicated in patients with: Pure red cell aplasia (PRCA) that begins after treatment with Aranesp, EPOGEN, or other erythropoietin protein drugs, Serious allergic reactions to Aranesp or EPOGEN. Aranesp and EPOGEN increase the risk of seizures in patients with CKD. OK 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. A single hemoglobin excursion may not require a dosing change. A BlandAltman analysis [10] was also performed to assess the agreement between ESA doses in the evaluation periods. Changes in ESA dosing and number of transfusions post-switch may have important health-economic implications. 4 x previous weekly epoetin alfa dose (Units)/125, e.g., 4 x 1500 Units of epoetin alfa per week/125 = 48 mcg of Mircera once every 4 weeks, 4 x previous weekly darbepoetin alfa dose (mcg)/0.55, e.g., 4 x 20 mcg of darbepoetin alfa per week/0.55 = 145.5 mcg of Mircera once every 4 weeks. New anemia therapies: translating novel strategies from bench to bedside. Data were also manually reviewed prior to final analysis. The initial conversion factor was 200:1. The odds ratio for receiving a transfusion was twice as high in patients switched at a dose ratio less than 1 when compared to those switched at 1:1 or higher. Disclaimer. MIRCERA- methoxy polyethylene glycol-epoetin beta 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.

Dosage form: injection, solution Epoetin alfa (Eprex [JanssenCilag], Binocrit [Sandoz], and epoetin zeta (Retacrit, - Hospira UK): the initial dose is 150 IU kg-1 given subcutaneously three times per week.5 -7 Alternatively, epoetin alfa can be administered at an initial dose of 450 IU kg 1 subcutaneously once weekly.5-7 The maximum recommended dose is 900 IU kg-1 Secondly, the DCR was calculated on a subset of patients which constituted approximately two-thirds of the total enrolled. The study comprised a 14-month observation period. For patients who do not respond adequately, if the hemoglobin has not increased by more than 1 g/dL after 4 weeks of therapy, increase the dose by 25%. 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. These adverse reactions included myocardial infarction and stroke. In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL.
