Contributed by. 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. 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). Response rates are defined in two ways: 1) Hgb levels > 12 g/dL or 2) an increase in Hgb of 2 g/dL from baseline. Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality than other patients. 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). Careers. pediatric patients 5 to 17 years of age on hemodialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA. Logistic regression analysis showed a higher likelihood of a transfusion during the post-switch period among patients with a dose ratio at switching of <1. Erythropoietins: A common mechanism of action - Academia.edu Pure red cell aplasia (PRCA) that begins after treatment with Mircera or other erythropoietin protein drugs. 5). Hb hemoglobin. Injection: 2,000 Units/mL, 3,000 Units/mL, 4,000 Units/mL, 10,000 Units/mL, and 40,000 Units/mL of RETACRIT as a clear and colorless liquid in single-dose vials. 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). x]r9r}W#k Excluding patients receiving a transfusion within 90 days of or during either EP, the DCR was 1.21 (95% CI 1.09, 1.35). Reasons for low Hb, e.g., acute intercurrent events such as bleeding, were not reported. 1:1 reference line, BlandAltman analysis of agreement between, BlandAltman analysis of agreement between pre- and post-switch erythropoiesis-stimulating agent dose ( n, Hemoglobin level and weekly equivalent erythropoiesis-stimulating agent dose during the 14-month observation period., Red blood cell transfusions pre- and post-switch, Summary of the last hemoglobin concentrations recorded within 14 days prior to red, MeSH Excursions of Hb values above and below the range of 1012g/dL [9] were more common in the post-switch compared to the pre-switch period. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. New anemia therapies: translating novel strategies from bench to bedside.

Prise en charge anmie rnale - Nephro.blog Provided by the Springer Nature SharedIt content-sharing initiative, Over 10 million scientific documents at your fingertips, Not logged in For Adult Patients with CKD not on dialysis: Refer patients who self-administer Mircera to the Instructions for Use [see Patient Counseling Information (17)]. [3] It is the first approved, chemically modified erythropoiesis-stimulating agent (ESA). Conclusion: A dose approximating 0. Mircera would also have competed with Aranesp and with Procrit . By Month 7 post-switch, the proportions of patients with Hb in these ranges were 9.7%, 48.1%, and 30.1%, respectively. This article does not contain any studies with human or animal subjects performed by any of the authors. 1: 21% of the excluded patients had died or were lost to follow-up during the post-switch period; 45% were no longer receiving PEG-Epo by Months +6 and +7 post-switch; and 34% had no Hb value reported for one or both EPs. W\iA* Individualize dosing and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions [see Warnings and Precautions (5.1)]. Accessibility The baseline (i.e., at time of switch) demographic and clinical characteristics of enrolled patients and those included in and excluded from the DCR analysis are displayed in Table1. 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. Administer supplemental iron therapy when serum ferritin is less than 100 mcg/L or when serum transferrin saturation is less than 20%. Inflammation and Erythropoiesis-Stimulating Agent Response in Hemodialysis Patients: A Self-matched Longitudinal Study of Anemia Management in the Dialysis Outcomes and Practice Patterns Study (DOPPS). Longer-acting PEG-Epo contains a chemical bond between an amino group present in epoetin beta and methoxy polyethylene glycol (PEG) butanoic acid; the addition of PEG is responsible for an increase in serum half-life of epoetin beta, and in CKD patients on dialysis the terminal half-life of PEG-Epo after IV administration is 134h [6, 8]. 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 .
