CERA HEMODIALYSIS

Erythropoiesis-stimulating agents (ESA) are used to treat anemia in hemodialysis (HD) patients. We investigated the role of inflammation and accumulation of environmental toxins (perfluorinated chemicals (PFCs), such as perfluorooctanoic acid and perfluorooctane sulfonate) in the erythropoietic response of HD patients who receive a fixed monthly continuous erythropoietin receptor activator (CERA) dosage. Forty-five patients underwent three successive phases of ESA treatment for two months each (phase one: 100 µg CERA once monthly; phase two: 50 µg CERA twice monthly; phase three: 100 µg CERA once monthly)...

BACKGROUND: Responsiveness to erythropoiesis-stimulating agents (ESAs) has been reported to be associated with increased cardiovascular disease (CVD) and mortality in patients undergoing hemodialysis (HD). However, the association between hyporesponsiveness to the long-acting ESA, epoetin beta pegol (CERA), and CVD remains unknown. METHODS: This multicenter prospective study included 4034 patients undergoing maintenance HD. After shifting from prior ESA to CERA, we studied the association between erythropoietin resistance index (ERI) at six months and outcomes, including cardiac events, major adverse cardiovascular events (MACE), and all-cause mortality, using Cox proportional hazards models (Landmark analyses) and marginal structural models to adjust for time-dependent confounding factors, including iron-containing medications and hemodiafiltration (HDF)...

BACKGROUND: The monthly continuous erythropoietin receptor activator (CERA) utilization maintains stable hemoglobin (Hb) after conversion from weekly epoetin-β (EB); however, how the different pharmacologic properties affect the red blood cell (RBC) size determined by RBC distribution width (RDW) has not been evaluated yet. We assess the potential differences in iron metabolism, plasma erythropoietin (EPO), hepcidin, and soluble α-Klotho (α-Klotho) levels as an emergent hematopoiesis factor...

Our previous randomized controlled trial comparing the total dose of weekly versus biweekly continuous erythropoietin receptor activator (CERA) therapy to maintain optimal hemoglobin (Hb) levels showed no significant differences between the two therapies. This post-hoc analysis assessed whether the total dose of weekly versus biweekly CERA therapy to maintain Hb levels among HD patients differed among groups with or without iron supplementation. Of 107 patients, 40 received intravenous iron supplementation due to iron deficiency (iron group) and 67 did not (non-iron group)...

BACKGROUND: This study aimed to determine associations among short- and long-acting erythropoiesis stimulating agents (ESAs), changes in serum fibroblast growth factor 23 (FGF23) and biomarkers of iron metabolism. METHODS: Among 108 patients on hemodialysis (HD), 44 received every 2 weeks or monthly doses of continuous erythropoiesis receptor activator (CERA), 31 received weekly doses of darbepoetin-α, 24 received three doses per week of epoetin-β and 9 were not treated with an ESA...

Although continuous erythropoietin receptor activators (CERAs) are widely used erythropoiesis-stimulating agents for correcting renal anemia in patients undergoing hemodialysis (HD), few reports have examined weekly CERA administration. In this randomized controlled trial, we compared the efficacy and changes in the parameters of iron metabolism and erythropoiesis between weekly and biweekly CERA administration. In total, 120 patients undergoing maintenance HD were randomized to the weekly or biweekly group...

PURPOSE: Anemia is a common complication in dialysis patients, usually treated with erythropoietin (EPO). Among available EPOs and analogs, continuous erythropoietin receptor activator (CERA) and darbepoetin alfa (DA) are the only two agents with a long duration of action, although they have almost never been formally compared in terms of efficacy. We took advantage of an accidental disruption in CERA supply to study the effect of its replacement with DA in the same patients. METHODS: The clinical and biological characteristics of 154 hemodialysis patients were retrospectively reviewed during the last 3 months on CERA compared to the first 4 months after replacement by DA, both ASE being administered by IV route...

Objectives: There is a lack of data in Panama on the potential differences in total healthcare professional (HCP) time between routine administrations of short-acting erythropoietin simulating agents (ESAs) (i.e. epoetin alfa) and continuous erythropoietin receptor activator (CERA) (i.e. methoxy polyethylene glycol-epoetin beta). This study aimed to quantify the HCP time associated with a single administration of epoetin alfa and CERA for the treatment of anemic patients with chronic kidney disease (CKD) on hemodialysis...

This national, prospective and multicenter study aimed to describe the real-life impact of comorbidities on hemoglobin stability in patients with chronic kidney disease on hemodialysis, treated with CERA in relay of an erythropoietin stimulating agent. Comorbidities were defined by the Charlson Index (adjusted on age) and hemoglobin stability as a variation of ±1g/dL after the 6-month treatment period. The 585 analyzed patients were distributed as follows according to the adjusted Charlson index: score≤3 (12% of patients), 4≤score≤5 (17%), 6≤score≤7 (31%) and score≥8 (40%)...

Recent evidence on maintenance administration of epoetin beta pegol, a continuous erythropoiesis receptor activator (CERA), in dialysis patients shows the clinical benefit of bi-weekly administration (Q2W) in improving hematopoiesis and iron use efficiency. We undertook a single-center observational study of 33 Japanese maintenance dialysis patients, whose anemia had been kept stable through weekly administration (Q1W) of darbepoetin (DA), to evaluate the effectiveness of CERA Q2W switched from DA in maintaining hemoglobin (Hb) levels over a 12-month period...

BACKGROUND: Clinicians providing dialysis care have numerous erythropoiesis-stimulating agents (ESAs) available for treating anemia. We sought to provide a contemporary description of ESA types used in hemodialysis (HD) settings in nine European countries. METHODS: Our study uses Dialysis Outcomes and Practice Patterns Study phase 5 (2012-2015) data from nine European countries (Belgium, France, -Germany, Italy, Russia, Spain, Sweden, Turkey, and the United Kingdom)...

Background: We determined optimal serum ferritin for oral iron therapy (OIT) in hemodialysis (HD) patients with iron deficiency anemia (IDA)/minor inflammation, and benefit of intravenous iron therapy (IIT) for OIT-nonresponders. Methods: Inclusion criteria were IDA (Hb <120 g/L, serum ferritin <227.4 pmol/L). Exclusion criteria were inflammation (C-reactive protein (CRP) ≥ 5 mg/L), bleeding, or cancer. IIT was withheld >3 months before the study. ΔHb ≥ 20 g/L above baseline or maintaining target Hb (tHB; 120-130 g/L) was considered responsive...

Anemia in chronic kidney disease (CKD) is a risk factor for cardiovascular diseases and is treated by long-acting erythropoiesis-stimulating agents (ESAs). Although the results of previous studies have shown that hemoglobin levels could not be maintained at the initiation of dialysis in CKD patients treated with recombinant human erythropoietin, it remains undetermined whether long-acting ESAs are effective in preventing the progression of anemia at the initiation of dialysis. In the present study, hemoglobin levels in 40 CKD patients treated with darbepoetin alfa (DA) and 15 CKD patients treated with a continuous erythropoietin receptor activator (CERA) were retrospectively compared during the 6 months period before the initiation of dialysis...

OBJECTIVE: The response of erythropoietic stimulating agents (ESA) in uremic patients may be associated with the changes of biochemical parameters, metal elements and inflammation status during the shift from one ESA to another. METHOD: We compared changes in above mentioned factors after switching from darbepoetin-α (DPO) 20μg weekly for 10 weeks to continuous erythropoietin receptor activator (CERA) 100μg monthly for 10 weeks in uremic patients on hemodialysis...

BACKGROUND: We aimed to identify associations between erythroferrone (ERFE), a regulator of hepcidin 25, and biomarkers of erythropoiesis and iron metabolism. We also aimed to determine the effects of erythropoiesis-stimulating agents (ESA), continuous erythropoietin receptor activator (CERA) and darbepoetin-α (DA) on ERFE production in patients on hemodialysis (HD). METHODS: Blood samples were obtained from 59 patients before HD sessions on day 0 (baseline). Twenty patients who were injected with either CERA (N = 10) or DA (N = 10) at the end of the dialysis week (day 0), who had ferritin ≥ 100 ng/mL and/or transferrin saturation ≥ 20%, and hemoglobin > 9 g/dL were selected from among the 59 patients...

OBJECTIVE: The purpose of this study was to determine the cost-utility of treating anemic dialysis patients with continuous erythropoietin receptor activator (CERA) once monthly or Epoetin Beta (EpoB) thrice weekly compared with a reference strategy of managing anemia with red blood cell transfusion (RBCT). METHODS: Cost-utility analysis study design. Decision analysis model, National health care payer, over 1 year with the publicly funded health care system. Chronic hemodialysis patients with renal anemia were included...

Continuous erythropoietin receptor activator (CERA) and darbepoetin-α (DA) might differently affect iron metabolism and erythropoiesis in patients on hemodialysis (HD). This prospective study examined a cohort of patients on HD who had received either intravenous CERA every 2 or 4 weeks (N = 25) or DA once each week (N = 47). Blood was sampled before HD sessions on days 0, 2, 4, 7 and 14, and on days 0, 3, 5, 7 and 14 from patients who were injected with ESA at the beginning and end of the dialysis week, respectively...

In early 2012, due to national supply disruption, the methoxy-polyethylene glycol-epoetin beta (CERA) was no longer available and has been replaced by darbepoetin alfa (DA) in all dialysis patients. Official recommendations for the replacement of one by the other is missing or unclear. On this occasion, we wanted to examine how the shift from CERA to DA was done in terms of dose conversion factor and the other factors that could have influenced the dose of DA prescribed (hemoglobin, patient weight, dose of CERA)...

Hypo-responsiveness to erythropoiesis-stimulating agents (ESAs) has been associated with increased mortality in end-stage renal disease patients. It is not clear if this effect is related to the elevated ESAs dosage for targeting hemoglobin levels or underlying morbid conditions that lead to ESA resistance. We retrospectively evaluated from 2008 to death or December 2011, 28 consecutive incident hemodialysis patients. We identified 2 cohort of patients based on their mean annual ESAs dosage. The correlation between data was evaluated with the Spearman's rho test...
