CERA HEMODIALYSIS

BACKGROUND/AIMS: We investigated the method of switching EPO to CERA that does not cause a decrease in the Hb level. METHODS: Fifty EPO-treated patients were randomly divided into two groups in which CERA was administered every two weeks (Q2W) or every four weeks (Q4W). After 8 weeks of treatment, the frequency of administration was changed to Q4W in the former. Follow-up was performed for 24 weeks. RESULTS: There was no difference in the Hb level between the two groups until 6 weeks...

Epoetin beta pegol is a continuous erythropoietin receptor activator (CERA) with a long half-life. Although CERA has been shown to maintain adequate hemoglobin (Hb) levels at prolonged dosing intervals, the optimal dosing schedule remains unclear. We therefore compared the efficacy of maintaining hemoglobin levels with administration of twice-monthly CERA (TWICE) versus once-monthly CERA (ONCE). Twenty hemodialysis patients receiving epoetin beta (EPO) were enrolled in this crossover study. Patients were assigned to either the TWICE or the ONCE group based on matching Hb levels and EPO doses...

This study aimed to evaluate the effect of different timings of iron administration during erythropoiesis activated by continuous erythropoietin receptor activator (CERA) on reticulocyte iron uptake in hemodialysis patients. In total, 110 patients were randomized to receive 40 mg intravenous elemental iron doses at all three hemodialysis sessions in the first week (IW1 group: n = 57) or in the third week (IW3 group: n = 53) after CERA administration. Following CERA administration at day 0, reticulocyte count increased, peaking at day 7...

Despite extensive use, to the best of our knowledge, no trial has simultaneously compared the three currently used erythropoietin-stimulating agents (ESAs) in a prospective manner in the treatment of anemia of end-stage renal disease patients. All hemodialysis patients in Qatar who were treated with short-acting epoetin alfa or beta have been screened. Eligible patients had been prospectively randomized, either to continue on the previous regimen of epoetin or to receive darbepoetin alfa or continuous erythropoietin receptor activator (CERA) for a total period of 40 weeks...

Epoetin beta pegol (a continuous erythropoietin receptor activator; CERA) is usually administered once in 4 weeks or once monthly. However, the optimal dosing interval remains unknown. We, therefore, compared the effect of CERA administration between dosing intervals of 2 weeks (TWICE group) and 4 weeks (ONCE group) on erythropoiesis and iron metabolism in 20 hemodialysis patients. CERA was administered intravenously at weeks 0 and 2 for the TWICE group, and at week 0 for the ONCE group. Levels of hemoglobin (Hb), reticulocyte count, ferritin, transferrin saturation, content of Hb in reticulocytes and hepcidin-25 were monitored weekly for 4 weeks...

Inadequate iron availability limits the response to erythropoiesis-stimulating agents (ESA) and hepcidin is a key regulator of iron metabolism. However, there is little information concerning time-dependent changes in hepcidin in response to the change of accelerated iron demand due to ESA-induced erythropoiesis. In this study, iron-related parameters, including hepcidin levels, were explored in comparison to patients receiving continuous erythropoietin receptor activator (CERA) and epoetin beta (EPO) treatment...

Continuous erythropoietin receptor activator (CERA) is an erythropoietin with a long-half life. This study investigated the efficacy of CERA for correcting anemia in Korean patients on dialysis. Patients (≥ 18 yr) who were not receiving any ESAs for more than 8 weeks were randomly assigned to either intravenous CERA once every 2 weeks (n=39) or epoetin beta thrice-weekly (n=41) during a 24-week correction phase. Hemoglobin (Hb) response was defined as increase of Hb by at least 1 g/dL and Hb ≥ 11 g/dL without red blood cell (RBC) transfusion...

Methoxy polyethylene glycol-epoetin beta, a continuous erythropoietin receptor activator (CERA), is reported to be effective in managing renal anemia but there is little data about CERA in Japan. This study aimed to ascertain the effects of CERA in Japanese hemodialysis patients and the appropriate starting dose of CERA when switching from other erythropoiesis-stimulating agents. We switched 61 stable hemodialysis patients to 4-weekly intravenous CERA, from either epoetin beta (rHuEPO) or darbepoetin alpha (DA)...

INTRODUCTION: Anemia is a well-documented consequence of chronic kidney disease, its frequency increases with the progression of renal failure and occurs in up to 95% of patients with end stage renal disease (ESRD). Erythropoietin stimulating agents (ESAs) have become the standard of care in the treatment of renal anemia. The use of methoxy polyethylene glycol-epoetin beta, continuous erythropoietin receptor activator, represents an important benefit in clinical practice. AIM: The aim of the OPATIJA study was to compare the efficacy and safety of maintaining hemoglobin levels in dialysis patients and to assess its variability in a parallel-group design...

Epoetin-induced pure red cell aplasia (PRCA) is most commonly associated with epoetin-a; nevertheless, its occurrence has been reported in epoetin-β and darbepoetin-a. We report a young hemodialysis patient who developed PRCA 2 years after receiving intravenous epoetin-β. Epoetin- induced PRCA was confirmed by bone marrow aspiration, associated with markedly elevated anti-erythropoietin antibody. He was treated with prednisolone and cyclophosphamide for 3 months but continued to be transfusion-dependent. 17 months after the development of PRCA, he was started on intravenous continuous erythropoiesis receptor stimulator (CERA) in view of frequent transfusions...

OBJECTIVES: Erythropoiesis-stimulating agents (ESA) are the main treatment for anemia in hemodialysis (HD) patients. We evaluated factors determining the response after treatment of a new ESA (continuous erythropoietin erythropoietin receptor activator (CERA)). METHODS: 61 HD patients were classified by their response at two different timings. First, patients whose hematocrit (Hct) increased 1.5% in the first week were defined as initial responders (IR, n = 16)...

Once-monthly administration of CERA, a continuous erythropoietin receptor activator, has shown equivalent efficacy to shorter-acting erythropoiesis-stimulating agents (ESAs) that require more frequent dosing, but data on routine use of once-monthly CERA in hemodialysis patients are lacking. Study on Efficacy, Safety and Applicability of Mircera (SESAM) was a prospective, multicenter, noninterventional trial with a duration of up to 9 months (month 0-5 "titration phase"; month 6-8 "evaluation phase") to test the stability of Hb control in hemodialysis patients under routine conditions...

Anemia has been linked to increased mortality and morbidity in renal hemodialysis patients. Other risk factors that contribute to an adverse outcome include the variability of hemoglobin (Hb) levels and the decreased response to erythropoiesis-stimulating factors (ESFs). In this study we evaluated the effectiveness of four different ESFs (epoetin-A, epoetin-B, darbepoetin, and CERA), assessed the variability of Hb levels, and compared ESF dosages which contributed to the achievement of Hb levels in each individual patient with renal failure undergoing chronic hemodialysis maintenance...

BACKGROUND: Recently cell-free plasma DNA has been described as a marker of apoptosis during hemodialysis (HD), but little is known about how different dialysis membranes may contribute to this process or whether pre-HD levels are restored afterwards. Here we evaluate the influence of the dialysis membrane on cell-free plasma DNA levels and investigate the clearance of plasma circulating DNA after HD. METHODS: Cell-free plasma DNA was measured using a real-time quantitative PCR for the beta-globin gene...
