Abstract
PURPOSE To assess whether erythropoiesis-stimulating agents (ESA) administration impacts the outcomes of patients with HER2-positive early breast cancer (EBC). METHODS ALTTO (NCT00490139) patients were categorized by ESA use during adjuvant anti-HER2 treatment. Disease-free-survival (DFS), overall survival (OS), and time-to-distant recurrence (TTDR) were analyzed by ESA administration, with subgroup analyses according to prognostic factors. Log-rank tests and Cox modeling were performed. Adverse events (AEs) of ESA-interest were compared. RESULTS Among 8381 patients recruited in ALTTO, 123 (1.5%) received ESA concomitantly with study treatment. The median age of patients receiving ESA was 54 years, 39.0% premenopausal, most had tumor size > 2 cm (56.9%), node-positive (58.5%), and positive estrogen receptor expression (61.8%). Median follow-up was shorter in the ESA group [6.1 years (IQR 5.3-7.0) vs. 6.9 years (6.0-7.1); p < 0.001]. There was no DFS difference by ESA administration (log-rank p = 0.70), with 3- and 7-year DFS of 89.2% (95% CI 81.8-93.8%) and 81.6% (71.4-88.5%) in ESA group vs. 88.3% (87.6-89.0%) and 80.0% (79.1-80.9%) in No-ESA group. In subgroup analyses, the interaction of ESA administration with menopausal status was statistically significant (unadjusted p = 0.024; stratified p = 0.033), favoring premenopausal women receiving ESA. We observed no significant association of ESA administration with OS (log-rank p = 0.57; 7-year OS in ESA 88.6% vs. 90.0% in non-ESA) or TTDR. ESA-interest AEs were experienced by eight (6.5%) patients receiving ESA and 417 (5.1%) in the No-ESA group (p = 0.41). CONCLUSION ESA administration to patients receiving adjuvant anti-HER2 treatment for HER2-positive EBC was safe and not associated with a negative impact on survival outcomes.

Abstract
PURPOSE Anemia in cancer should be diagnosed and treated according to guideline recommendations. The implementation of ESMO and German guidelines and their effect on anemia correction was analyzed. METHODS This retrospective epidemiological study, representative for Germany, analyzed data on anemia management of cancer patients with anemia ≥ grade 2. The Guideline Adherence Score (GLAD) for diagnosis (GLAD-D) and therapy (GLAD-T) was defined as follows: 2 points for complete, 1 point for partial, 0 point for no adherence. RESULTS Data were analyzed for 1046 patients. Hb levels at diagnosis of anemia were 8-10 g/dL in 899 (85.9%) patients, 7-8 g/dL in 92 (8.7%), and < 7 g/dL (5.0%) in 52. Transferrin saturation was determined in 19% of patients. Four hundred fifty-six patients received RBC (43.6%), 198 (18.9%) iron replacement, 106 (10.1%) ESA, and 60 (5.7%) vitamin B12 replacement. 60.6% of patients receiving iron replacement were treated intravenously and 39.4% were treated orally. Two hundred eighty-eight (36.6%) of 785 patients receiving transfusions had no guideline-directed indication. GLAD-D was 2 in 310 patients (29.6%), 1 in 168 (16.1%), and 0 in 568 (54.3%). GLAD-T was 2 in 270 patients (25.8%), 1 in 320 patients (30.6%), and 0 in 456 patients (43.6%). Higher GLAD-D significantly correlated with higher GLAD-T (τB = 0.176, p < 0.001). GLAD-T 2 was significantly associated with greater Hb increase than GLAD-T 0/1 (p < 0.001) at 28 days (10.2 vs. 9.7 g/dL) and at 2 months (10.4 vs. 9.9 g/dL). CONCLUSIONS Anemia assessment is inadequate, transfusion rates too high, and iron and ESA therapy too infrequent. TRIAL REGISTRATION ClinicalTrials.gov, NCT05190263, date: 2022-01-13.

Abstract
Anemia is a frequent and early chronic kidney disease (CKD) complication. Its management is currently based on oral or intravenous iron supplements, erythropoiesis-stimulating agents, and red blood cell transfusions, when the benefits of transfusion outweigh the risks. Anemia in CKD patients is underdiagnosed and undertreated. Current standard of care is associated with challenges and therefore new treatment approaches have been sought. Hypoxia-inducible factor-prolyl-hydroxylase enzyme inhibitors are a new class of orally administered drugs used to treat anemia associated with CKD. Small-molecule hypoxia-inducible factor-prolyl-hydroxylase inhibitors have a novel mechanism of action that activates the hypoxia-inducible factor (oxygen-sensing) pathway resulting in a coordinated erythropoietic response, leading to increased endogenous erythropoietin production, improved iron absorption and transport, and reduced hepcidin. Roxadustat is the first hypoxia-inducible factor-prolyl-hydroxylase inhibitor approved by the European Medicines Agency (EMA) and reimbursed in Italy by the Italian Medicines Agency (AIFA) for the treatment of adult patients with symptomatic CKD-related anemia. This authorization was based on the outcome of a globally-conducted phase 3 clinical trial program comprising eight pivotal multicenter randomized studies. In the absence of up-to-date guidelines, we performed a critical appraisal of the placement and use of roxadustat in this therapeutic context.

Abstract
BACKGROUND AND OBJECTIVE Studies on the prevalence of anaemia in chronic kidney disease in adults not on dialysis (CKD-ND) and in dialysis programmes (CKD-D) in Spain are not recent or focus on certain subgroups. The aim of this study was to know the epidemiology and current treatment patterns of anaemia associated with CKD in Spain. MATERIALS AND METHODS Multicentre, non-interventional, retrospective study with CKD-ND stage 3a-5 and CKD-D patients treated in Spain between 2015 and 2017 (RIKAS study). RESULTS The prevalence of anaemia in CKD-ND and CKD-D in 2015 was 33.8% and 91.5%, respectively, with similar results during 2016-2017. The prevalence of systemic inflammation in anaemic patients (18.1% and 51.8% for CKD-ND and CKD-D, respectively) was higher, especially in those treated with erythropoiesis-stimulating agents (ESA), compared to the general population with CKD-ND. After 12 months of follow-up, mean ferritin and transferrin saturation index (TSI) values in anaemic patients with CKD-ND were 187.1 ng/mL and 22.2%, respectively, while in CKD-D were 254.6 ng/mL and 20.2%. In ESA-treated patients, mean values were 190.6 ng/mL and 22.0% in ND-CKD, and 255.0 ng/mL and 20.2% in D-CKD. CONCLUSIONS The prevalence of anaemia and inflammation increased with the disease severity, being higher in D-CKD. Iron parameters in anaemic patients treated or not with ESA are insufficient according to the guidelines, so there is room for improvement in the treatment of anaemia associated with CKD.

Abstract
Erythropoiesis-stimulating agents (ESAs) have been reported to increase the risk of death in cancer patients. In this study, we selected breast cancer, which is currently the most prevalent cancer worldwide, for a meta-analysis to re-examine the advantages and disadvantages of using ESAs. All relevant studies were searched by PubMed, Embase, Web of science, and Cochrane Library. Endpoints including mortality, incidence of thrombo-vascular events, hemoglobin, and transfusion requirements were meta-analyzed based on random-effects model or fixed-effect model. 10 studies were finally included, with a total sample size of 6785 patients. The risk of mortality was higher in patients using ESA than in controls (RR 1.07, 95% CI 1.01-1.13, P = 0.03); subgroup analysis found that the mortality rate was higher in patients treating with ESA for > 6 months (RR 1.27, 95% CI 1.05-1.55, P = 0.01) and epoetin α (RR 1.07, 95% CI 1.01-1.14, P = 0.03). The incidence of thrombo-vascular adverse events was higher in patients using ESA than in controls (RR 1.53, 95% CI 1.27-1.86, P < 0.0001). The ESA group was more effective in improving anemia in cancer patients (MD 1.20, 95% CI 0.77-1.63, P < 0.00001). The blood transfusion needs of patients in the ESA group were significantly lower (RR 0.52, 95%CI 0.44-0.60, P < 0.00001). There was no statistically significant difference between the two groups in disease progression-related conditions (HR 1.03, 95%CI 0.95-1.12, P = 0.52). ESAs increase the risk of mortality and the incidence of thrombo-vascular adverse events in breast cancer patients, while reducing their anemia symptoms and transfusion requirements.

Abstract
Anemia is a common complication of kidney disease and the prevalence increases as the disease progresses. It worsens the quality of life of patients and increases morbidity and mortality. The current rationale for treating renal anemia is based on the use of erythropoiesis-stimulating agents, iron supplementation and, to a lesser extent, the use of transfusions. Stimulation of endogenous erythropoietin synthesis and improvement of iron availability, through inhibition of prolil-hydroxilase- hypoxia-inducible factor (PH-HIF), represents a new oral alternative for renal anemia treatment. Clinical trials with PH-HIF inhibitors have demonstrated their efficacy in maintaining target hemoglobin levels. However, aspects concerning long-term safety are pending a clarification. In conclusion, advances in the pathogenesis of renal anemia make it possible to have current treatments to treat renal anemia. The development of new molecules, based on the inhibition of PH-HIF, represents a new effective alternative for anemia associated with kidney disease, especially in patients with resistance to erythropoiesis-stimulating agents.

Abstract
BACKGROUND Iron supplementation and erythropoiesis-stimulating agent (ESA) administration represent the hallmark therapies in preoperative anemia treatment, as reflected in a set of evidence-based treatment recommendations made during the 2018 International Consensus Conference on Patient Blood Management. However, little is known about the safety of these therapies. This systematic review investigated the occurrence of adverse events (AEs) during or after treatment with iron and/or ESAs. METHODS Five databases (The Cochrane Library, MEDLINE, Embase, Transfusion Evidence Library, Web of Science) and two trial registries (ClinicalTrials.gov, WHO ICTRP) were searched until 23 May 2022. Randomized controlled trials (RCTs), cohort, and case-control studies investigating any AE during or after iron and/or ESA administration in adult elective surgery patients with preoperative anemia were eligible for inclusion and judged using the Cochrane Risk of Bias tools. The GRADE approach was used to assess the overall certainty of evidence. RESULTS Data from 26 RCTs and 16 cohort studies involving a total of 6062 patients were extracted, on 6 treatment comparisons: (1) intravenous (IV) versus oral iron, (2) IV iron versus usual care/no iron, (3) IV ferric carboxymaltose versus IV iron sucrose, (4) ESA+iron versus control (placebo and/or iron, no treatment), (5) ESA+IV iron versus ESA+oral iron, and (6) ESA+IV iron versus ESA+IV iron (different ESA dosing regimens). Most AE data concerned mortality/survival (n=24 studies), thromboembolic (n=22), infectious (n=20), cardiovascular (n=19) and gastrointestinal (n=14) AEs. Very low certainty evidence was assigned to all but one outcome category. This uncertainty results from both the low quantity and quality of AE data due to the high risk of bias caused by limitations in the study design, data collection, and reporting. CONCLUSIONS It remains unclear if ESA and/or iron therapy is associated with AEs in preoperatively anemic elective surgery patients. Future trial investigators should pay more attention to the systematic collection, measurement, documentation, and reporting of AE data.

Abstract
Although many studies have shown that supplementation with iron and erythropoiesis-stimulating agents (ESA) is frequently used for managing chemotherapy-induced anemia (CIA), optimal combination therapy using these agents together to ameliorate anemia is not well characterized. To assess the effects of ESA combined with oral or intravenous (IV) iron on relieving CIA, PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI) were searched for articles. Data collected in the articles were meta-analyzed using RevMan 5.3 software with a random-effects model. Our comprehensive search yielded 1666 potentially relevant trials. A total of 41 trials randomizing 4200 patients with CIA fulfilled inclusion criteria, including 34 Chinese articles and 7 English articles. Meta-analysis showed that treatment with both ESA and iron more effectively improved CIA relative to iron supplementation alone, with increased hemoglobin, hematocrit, red blood cell count and haematopoietic response rate. Subgroup analyses revealed iron administration, both oral and IV iron, improved anemia in ESA-treated cancer patients with CIA. Our analysis demonstrates that iron supplementation combined with ESA more effectively ameliorates CIA relative to iron supplementation alone, without regard to whether IV or oral iron was used. Together, our findings may contribute to the clinical treatment of CIA using iron therapy with or without ESA. This article is protected by copyright. All rights reserved.

Abstract
INTRODUCTION This study examines factors associated with erythropoiesis-stimulating agent (ESA) hyporesponsiveness, the duration of ESA hyporesponsiveness, the frequency of new episodes, and variation across countries. METHODS We used international Dialysis Outcomes and Practice Patterns Study data from 2015 to 2018 (N = 26,656) to investigate changes in ESA Resistance Index (ERI), calculated as epoetin dose divided by [hemoglobin × body weight] in patients on hemodialysis. We illustrated the proportion of patients who moved to other ERI quintiles over 12 months, and we studied the incidence and duration of ESA resistance. We examined case-mix factors associated with quintiles of ERI. RESULTS Most patients migrated out of their original ERI quintile within 4 months. Only 22% of patients in the top quintile of ERI at baseline (4.4% of all patients) remained in the top quintile during all 12 months of follow-up. A total of 42% of patients manifested an upper-quintile ERI during at least 1 month. Median duration of a new episode of ESA resistance was 2 months. Catheter hemoaccess, elevated C-reactive protein, lower transferrin saturation, lower serum albumin concentration, and recent hospitalization occurred more frequently among patients in the highest ERI quintile at baseline. ERI values were highest in the USA, Italy, and Mideastern nations and lowest in Russia and Japan. DISCUSSION/CONCLUSION It is a misconception to envision a sizable, fixed segment of the population with permanent resistance to ESA - resistance fluctuates frequently. The implications of these findings for prescription of ESAs and of hypoxia-inducible factor-prolyl hydroxylase inhibitors are discussed.

Abstract
PURPOSE OF THE REVIEW In this review paper, we examine the latest evidence regarding the use of iron supplementation, erythropoiesis-stimulating agents (ESAs), and blood transfusions as therapeutic targets for anemia to mitigate morbidity and mortality in patients with cardiovascular disease. RECENT FINDINGS Intravenous ferric carboxymaltose (FC) injections in heart failure (HF) have resulted in improved self-reported patient symptoms; higher exercise capacity, as measured by 6-min walk test distance in anemic patients; and lower re-hospitalization rates in iron deficient patients. Darbepoetin alfa has shown evidence of improved Kansas City Cardiomyopathy Questionnaire scores. No mortality benefits have been noted thus far with FC injections or darbepoetin in HF, with an increase in adverse events with darbepoetin. Aggressive transfusions (Hg < 10 g/dL) are not associated with improved outcomes in cardiovascular disease. Quality of life metrics, rather than mortality, appear to improve with IV FC and ESA use in HF. More studies are required to see if these treatments have a role in coronary artery disease. Current evidence suggests that anemia is a marker of underlying disease severity, with a limited role in disease modification. Further studies are required to solidify our understanding of this topic.

Abstract
Erythropoiesis-stimulating agents (ESAs) have improved the quality of life and reduced the need for transfusions in patients with chronic kidney disease. However, randomized trials showed no benefit but possible safety issues following high doses of ESAs given to reach normal hemoglobin levels. Iron therapy is used together with ESA; when given proactively, it may reduce the risk of mortality and cardiovascular events in hemodialysis patients. Recent trials also showed benefits of intravenous iron therapy in patients with heart failure. New drugs for correcting anemia may retain the present efficacy of ESAs as antianemic drugs and reduce cardiovascular risks.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) constitute an important treatment option for anemia in hemodialysis (HD) patients. We investigated the relationships among the dosage of ESA, erythropoietin resistance index (ERI) scores, and mortality in Chinese MHD patients. METHODS This multicenter observational retrospective study included MHD patients from 16 blood purification centers (n = 824) who underwent HD in 2011-2015 and were followed up until December 31, 2016. We collected demographic variables, HD parameters, laboratory values, and ESA dosages. Patients were grouped into quartiles according to ESA dosage to study the effect of ESA dosage on all-cause mortality. The ERI was calculated as follows: ESA (IU/week)/weight (kg)/hemoglobin levels (g/dL). We also compared outcomes among the patients stratified into quartiles according to ERI scores. We used the Cox proportional hazards model to measure the relationships between the ESA dosage, ERI scores, and all-cause mortality. Using propensity score matching, we compared mortality between groups according to ERI scores, classified as either > or ≤12.80. RESULTS In total, 824 patients were enrolled in the study; 200 (24.3%) all-cause deaths occurred within the observation period. Kaplan-Meier analyses showed that patients administered high dosages of ESAs had significantly worse survival than those administered low dosages of ESAs. A multivariate Cox regression identified that high dosages of ESAs could significantly predict mortality (ESA dosage >10,000.0 IU/week, HR = 1.59, 95% confidence intervals (CIs) (1.04, 2.42), and p = 0.031). Our analysis also indicated a significant increase in the risk of mortality in patients with high ERI scores. Propensity score matching-analyses confirmed that ERI > 12.80 could significantly predict mortality (HR = 1.56, 95% CI [1.11, 2.18], and p = 0.010). CONCLUSIONS Our data suggested that ESA dosages >10,000.0 IU/week in the first 3 months constitute an independent predictor of all-cause mortality among Chinese MHD patients. A higher degree of resistance to ESA was related to a higher risk of all-cause mortality.

Abstract
BACKGROUND Recent studies have suggested that erythropoiesis-stimulating agents (ESAs) may accelerate not only angiogenesis but also vasculogenesis, beyond erythropoiesis. METHODS We conducted a 12-week prospective study in 51 dialysis patients; 13 were treated with recombinant human erythropoietin (EPO, 5290.4 ± 586.9 IU/week), 16 with darbepoetin (DA, 42.9 ± 4.3 µg/week), 12 with epoetin β pegol (CERA, 40.5 ± 4.1 µg/week) and 10 with no ESAs. Vascular mediators comprising endothelial progenitor cells (EPCs), vascular endothelial growth factor (VEGF), matrix metalloproteinase-2 (MMP-2), and high-sensitivity C-reactive protein (hs-CRP) were measured at 0 and 12 weeks. EPCs were measured by flow cytometry as CD45lowCD34+CD133+ cells. RESULTS The EPC count increased significantly to a greater extent in the EPO group than in the other three group, and increased significantly from 0 to 12 weeks in a EPO dose-dependent manner. In both the DA and CERA groups, the EPC count did not change at 12 weeks. Serum levels of VEGF, MMP-2 and hs-CRP were not affected by ESA treatment in all groups. In the CERA group, serum ferritin decreased significantly compared to the no-ESA group and correlated with CERA dose, although use of iron was permitted if required during the prospective study period of 12 weeks. CONCLUSIONS When patients on dialysis were treated with clinical doses of various ESAs, only EPO induced a significant increase of circulating EPCs from bone marrow, whereas, DA and CERA had no effect.

Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) have revolutionized the therapeutic strategy for anemia in chronic kidney disease. However, some cases are resistant or hyporesponsive to ESAs. Roxadustat is an oral hypoxia-inducible factor-prolyl hydroxylase inhibitor that stimulates erythropoiesis and regulates iron metabolism. Here, we describe a hemodialysis patient with refractory anemia who did not respond to traditional treatments and depended on blood transfusion for more than 1 year. After applying Roxadustat, the patient’s anemia improved significantly.
CASE SUMMARY A 44-year-old man was diagnosed with uremia accompanied by severe anemia with a hemoglobin (Hb) level ranging from 30-40 g/L. His anemia did not improve after sufficient dialysis or high doses of active ESAs; other causes of anemia were excluded. The patient required approximately 600-1000 mL of red blood cell suspension every 15-30 d for more than 1 year. After accepting Roxadustat therapy, the patient’s anemia symptoms improved significantly; his Hb level gradually increased to 50 g/L, and no further blood transfusions were administered. His Hb level reached 69 g/L by the 34th week. Although a Hb level of 60-70 g/L cannot be considered satisfactory, he no longer required blood transfusions and his quality of life was substantially improved. Roxadustat showed good efficacy and safety in this case.
CONCLUSION Roxadustat represents an innovative and effective agent for the clinical treatment of renal anemia caused by multiple complex factors.

Abstract
While pregnancy-related malignancies are quite rare, their incidence is increasing and thus affecting more and more women nowadays. Their management, however, with both chemotherapy and supportive agents remains quite challenging and it seems crucial to define the optimal treatment for this special population. Concerning supportive medication, it is clinically significant to determine whether commonly used agents, including Granulocyte Colony-Stimulating Factors, Erythropoiesis-stimulating agents, Bisphosphonates, Anticoagulation agents, Antiemetics and Glucocorticoids are indeed effective in ameliorating chemotherapy side effects. Meanwhile, it is of great importance that the administration of any of these agents is safe for both mother and fetus. This review aims to provide a précis of the current literature regarding both safety and efficacy of all categories of supportive medication during pregnancy.

Abstract
Doping tests for the illegal use of erythropoiesis-stimulating agents (ESAs) have been developed. We developed a new Western blotting method to detect and distinguish endogenous erythropoietin (Epo, 35-38 kDa) and exogenous ESAs (epoetin α and β, 38-42 kDa; darbepoetin α, 47-50 kDa; epoetin β pegol, 93-110 kDa). Epo and ESAs are glycoproteins and deglycosylation using peptide-N-glycosidase F shifted all Epo and ESA bands except epoetin β pegol to 22 kDa. We cut the bands of Epo and ESAs from SDS-PAGE gels and analyzed them by Liquid Chromatography/Mass Spectrometry (LC/MS). LC/MS detected all endogenous Epo and exogenous ESAs as deglycosylated 22 kDa Epo, indicating that LC/MS analysis could confirm the presence of Epo or ESA, but could not distinguish between endogenous Epo and exogenous ESAs. We propose the following Epo doping tests: 1) detect Epo or ESAs by Western blotting of the glycosylated form; 2) increase the reliability by the band shift following deglycosylation; and 3) complete confirmation of Epo or ESA by LC/MS analysis using cut gels. One of the advantages of our method is that pre-purification of samples for Epo is not required in our Western blotting.

Abstract
BACKGROUND Hyporesponsiveness to erythropoiesis-stimulating agents (ESAs) is associated with cardiovascular events and poor renal outcome in patients with chronic kidney disease (CKD). This study aimed to investigate the initial responsiveness to darbepoetin alfa (DA) and its contributing factors using the data from the BRIGHTEN. METHODS Of 1980 patients enrolled at 168 facilities, 1695 were included in this analysis [285 patients were excluded mainly due to lack of hemoglobin (Hb) values]. The initial ESA response index (iEResI) was defined as a ratio of Hb changes over 12 weeks after DA administration per weight-adjusted total DA dose and contributing factors to iEResI were analyzed. RESULTS The mean age was 70 ± 12 years (male 58.8%; diabetic nephropathy 27.6%). The median creatinine and mean Hb levels at DA initiation were 2.62 mg/dL and 9.8 g/dL, respectively. The most frequent number of DA administration during 12 weeks was 3 times (41.1%), followed by 4 (15.6%) times with a wide distribution of the total DA dose (15-900 μg). Remarkably, 225 patients (13.3%) did not respond to DA. Multivariate analysis showed that male gender, hypoglycemic agent use, iron supplementation, high eGFR, low Hb, low CRP, low NT-proBNP, and low urinary protein-creatinine ratio were independently associated with better initial response to DA (P = < 0.0001, 0.0108, < 0.0001, 0.0476, < 0.0001, 0.0004, 0.0435, and 0.0009, respectively). CONCLUSIONS Non-responder to DA accounted for 13.3% of patients with non-dialysis CKD. Iron supplementation, low CRP, low NT-proBNP, and less proteinuria were predictive and modifiable factors associated with better initial response to DA.

Abstract
Myelodysplastic syndromes (MDS) are hematopoietic stem cell malignancies associated with an erythroid maturation defect, resulting in anemia. Treatments for MDS include erythropoiesis-stimulating agents (ESAs). The identification of prognostic markers is important to help predict response and improve outcomes. Various scoring systems have been developed to help predict response to ESAs. Despite limitations in its assessment, serum erythropoietin (sEPO) level is an important predictor of hematologic response to ESAs in patients with lower-risk MDS. Numerous studies have reported significantly lower sEPO levels among responders versus non-responders. Furthermore, treatment response is significantly more likely among those with sEPO levels below versus those above various cutoffs. Other prognostic indicators for response to ESAs include lower transfusion requirement, fewer bone marrow blasts, higher hemoglobin, lower serum ferritin, lower-risk MDS, and more normal cytogenetics. Studies of other MDS therapies (e.g., lenalidomide and luspatercept) have also reported that lower sEPO levels are indicative of hematologic response. In addition, lower sEPO levels (up to 500 IU/L) have been included in treatment algorithms for patients with lower-risk MDS to define whether ESAs are indicated. Lower sEPO levels are predictive of hematologic response—particularly to ESAs. Further, clinical trials should use sEPO thresholds to ensure more homogeneous cohorts.

Abstract
Erythropoietin (EPO) is an important hormone responsible for the stimulation of hematopoiesis which is impaired in a variety of diseases, such as chronic kidney disease, cancer chemotherapy, and the use of some anti-HIV drugs. Difficulties in the purification of endogenous EPO due to problems such as technical limitations, heterogeneity of target cells, inadequate amount and immunogenicity of the resultant product, had limited the entry of endogenous EPO in the clinical applications. The integration of medical biotechnology and hematology has introduced novel procedures for the production of human recombinant erythropoietin (rHuEPO), and other erythropoiesis-stimulating agents (ESAs). To investigate and produce rHuEPO, the first step is to recognize the molecular biology and functional pathways, structure, metabolism, and basic physiology of EPO. In this review, all clinical indications, side effects, challenges and notable points regarding EPO, rHuEPO, and other ESAs have also been addressed along with its molecular characterization, such as the modifications needed to optimize their rHuEPO biosynthesis.

Abstract
Background Evidences show that around 20% of biosimilar or originator erythropoiesis-stimulating agents (ESAs) users are hyporesponsive. Controversial post-marketing data exist on the predictors of ESA hyporesponsiveness. The aim of this study was to identify predictors of ESA hyporesponsiveness in patients with chronic kidney disease (CKD) or cancer in clinical practice. Methods During the years 2009–2015, a multi-center, population-based, cohort study was conducted using claims databases of Treviso and Caserta Local Health Units (LHUs). All incident ESA users were characterized at baseline and the differences between the baseline hemoglobin (Hb) value, that is the Hb registered within 30 days prior to the first ESA dispensing (index date, ID) and each outcome Hb value (registered between 30 and 180 days after ID) were calculated and defined as delta Hb (ΔHb). Incident ESA users were defined as hyporesponsive if, during follow-up, they registered at least one ΔHb < 0 g/dL. Including all potential predictors of ESA hyporesponsiveness and stratifying by indication for use, univariate and multivariate binary logistic regression models and Receiver Operating Characteristic (ROC) curves were carried out. Results In general, 1080 incident ESA users (CKD: 57.0%; cancer: 43.0%) were identified. In CKD, predictors of ESA hyporesponsiveness were C-reactive protein (OR = 1.2, 95% CI: 1.0–1.5; P-value = 0.060) and high levels of baseline Hb (OR = 1.7, 95% CI: 1.2–2.2; P-value< 0,001), the latter being also predictor of ESA hyporesponsiveness in cancer (OR = 1.7, 95% CI: 1.1–2.4; P-value = 0.007). Both in CKD and in cancer, the type of ESA, biosimilar or originator, was not a predictor of ESA hyporesponsiveness. In CKD, concomitant use of iron preparations (OR = 0.3, 95% CI: 0.2–0.7; P-value = 0.002) and of high dosage of angiotensin-converting enzyme inhibitors/angiotensin II-receptor blockers (OR = 0.5, 95% CI: 0.3–0.9; P-value = 0.022) were protective factors against ESA hyporesponsiveness. Conclusions The study confirmed traditional potential predictors of hyporesponsiveness to ESA. The use of biosimilar or originator ESA was not a predictor of hyporesponsiveness in an outpatient setting from two large Italian areas. A better knowledge of the predictors of ESA response would allow a better anemia management to improve patients’ quality of life.

Abstract
BACKGROUND A decreased response to erythropoiesis-stimulating agents (ESAs) leads to refractory anemia and worse prognosis in patients with chronic kidney disease. We examined the association between autoantibodies to the erythropoietin receptor (EPOR) and responsiveness to ESAs in patients on maintenance hemodialysis. METHODS A total of 108 Japanese patients on maintenance hemodialysis at three institutions were enrolled. Sera from these patients were screened for anti-EPOR antibodies using an enzyme-linked immunosorbent assay. An ESA resistance index (ERI) was calculated, and patients in the highest ERI quartile were defined as ESA hyporesponsive. RESULTS Anti-EPOR antibodies were detected in 11 patients (10%). Body mass index and hemoglobin, platelet, magnesium, and ferritin levels decreased with higher ERI levels. On the other hand, C-reactive protein (CRP) levels and the prevalence of anti-EPOR antibodies increased with higher ERI levels. In multivariate analysis, the presence of anti-EPOR antibodies together with CRP was a significant risk factor for ESA hyporesponsiveness. CONCLUSIONS Anti-EPOR antibodies were detected in patients on maintenance hemodialysis, and these autoantibodies were independent factors for hyporesponsiveness to ESAs in these patients.

Abstract
Bloodless autologous hematopoietic cell transplantation is associated with risks of severe bleeding and profound anemia. RBC or platelet transfusions are often used to prevent these hematologic complications. However, in patients such as Jehovah's Witnesses who refuse major blood components, the lack of transfusion support is not an absolute contraindication to an autologous hematopoietic cell transplant. Pennsylvania Hospital performed the world's first bloodless hematopoietic cell transplant more than 15 years ago and has gradually improved its technique with a sizable patient population. Erythropoiesis-stimulating agents were successfully employed as part of their pretransplant regimen to prevent severe anemia. Thrombopoietin agonists' potential role in bloodless transplant is also currently being explored. Although there is limited literature, available reports in combination with physiologic reasoning may support the use of these growth factors to promote transplant success. These agents offer potential benefit and may be of utility in minimizing complications of a bloodless transplant. In this review, we summarize the available literature and offer insight into how we may incorporate growth factors to allow bloodless autologous hematopoietic cell transplantation to be an available option to patients who may otherwise be denied.

Abstract
Since the introduction of erythropoiesis-stimulating agents (ESAs) into clinical practice in 1989, considerable effort has been put forth toward identifying the optimal treatment strategy for managing anemia of CKD. After initial treatment of only the most severely anemic patients, therapy was subsequently expanded to include most patients on dialysis and many nondialysis CKD patients. Many nephrology societies and regulatory agencies have sought to identify the most appropriate hemoglobin levels to which ESA therapy should be targeted. As increasing evidence became available about the impacts of ESAs on varying endpoints including morbidity, mortality, and quality of life, the guidelines put forth by such agencies evolved over time. We review the literature impacting these determinations through the past 3 decades and comment on how this informs the application of this knowledge to the care of patients today.

Abstract
Background Previous randomized-controlled trials have shown that targeting higher hemoglobin (Hb) levels using high dose of ESA in non-dialysis chronic kidney disease (NDCKD) patients resulted in poorer cardiovascular outcome; however, it remains unknown how high Hb levels achieved by ESA in clinical practice dose could affect renal outcome. Methods In a multicenter prospective observational study, Japanese NDCKD patients with an estimated glomerular filtration rate (eGFR) of ≥ 6 mL/min/1.73 m2 and renal anemia (Hb < 11 g/dL) treated with epoetin beta pegol (C.E.R.A.) for the first time were divided into two groups by Hb level (< 11 g/dL or ≥ 11 g/dL) in Week 12 of C.E.R.A. treatment (Week 12 Hb). Renal outcome was defined as time until the first occurrence of one of the following: progression to renal replacement therapy, serum creatinine doubling, or eGFR falling below 6 mL/min/1.73 m2. The effect of Week 12 Hb on the onset of renal events was assessed by the Kaplan–Meier and multivariate Cox regression analyses. Results In the landmark analysis which included 2851 patients, Kaplan–Meier renal survival rate was 37.57% in the < 11 g/dL group and was significantly higher (51.47%) in the ≥ 11 g/dL group (P < 0.0001). Multivariate Cox regression analysis revealed significantly higher risk of renal events in the < 11 g/dL group than in the ≥ 11 g/dL group (hazard ratio: 1.26; 95% confidence interval: 1.05–1.51; P = 0.0103). Conclusions The results suggest that week 12 Hb levels ≥ 11 g/dL achieved with C.E.R.A. treatment were associated with better renal outcomes than Hb levels < 11 g/dL.

Abstract
Background In dialysis patients, the obesity-survival paradox still requires an explanation. Anemia and high doses of erythropoiesis-stimulating agents (ESAs) are associated with worse outcomes in the hemodialysis (HD) population. In the present study, we explored the relation between obesity and anemia control in a sample of maintenance HD patients in Egypt. Methods This multicenter observational study included 733 patients on maintenance HD from 9 hemodialysis centers in Egypt. Clinical and laboratory data as well as average doses of ESAs and parenteral iron were recorded. The erythropoietin resistance index (ERI) was calculated. Results Obesity, defined as a body mass index (BMI) ≥ 30 kg/m2, was present in 22.6% of the studied population. The target hemoglobin level (10.0–11.5 g/dL) was achieved in 27.3% of non-obese and 25.3% of obese patients, with no significant difference. The median serum ferritin and the values of transferrin saturation index did not differ significantly between these two groups. The weekly ESA dose was significantly lower in obese than in non-obese patients (P = 0.0001). A trend toward higher ESA doses and ERI values was observed in patients with lower BMIs (P < 0.0001). Multiple linear regression revealed that the BMI and urea reduction ratio were the strongest predictors of the ERI. Conclusion Our study adds more evidence to obesity-associated advantages in HD patients. BMI may determine ESA response, with better responses observed in patients with higher BMIs.

Abstract
INTRODUCTION Anaemia is common in haemodialysis patients and treating it with erythropoiesis-stimulating agents (ESAs) is complex due to many factors. OBJECTIVES To assess the usefulness of the Anaemia Control Model (ACM) in the treatment of anaemia in haemodialysis. METHODS ACM is a software that predicts the optimal dose of darbepoetin and iron sucrose to achieve target haemoglobin (Hb) and ferritin levels, and makes prescription suggestions. Study conducted in dialysis clinics lasting 18months with two intervention phases (IPs) with ACM (IP1, n:213; IP2, n:218) separated by a control phase (CP, n:219). The primary outcome was the percentage of Hb in range and the median dose of ESAs, and the secondary outcomes were transfusion, hospitalisation and cardiovascular events. Clinical and patient analyses were performed. Hb variability was assessed by the standard deviation (SD) of the Hb. We also analysed the patients with most of the suggestions confirmed (ACM compliant group). RESULTS ACM increased the percentage of Hb in range: 80.9% in IP2, compared with 72.7% in the CP and reduced the intake of darbepoetin (IP1: 20 [70]; CP 30 [80] μg P=0.032) with less Hb fluctuation (0.91±0.49 in the CP to 0.82±0.37g/dl in IP2, P<0.05), improving in the ACM compliant group. The secondary outcomes decreased with the use of ACM. CONCLUSIONS ACM helps to obtain better anaemia results in haemodialysis patients, minimising the risks of treatment with ESAs and reducing costs.

Abstract
PURPOSE The aim of this multicenter prospective study was to evaluate efficacy and safety of biosimilar erythropoiesis-stimulating agents (ESAs) vs originator, based on data from clinical practice in patients with chronic kidney disease (CKD). METHODS We collected data of the patients with diagnosis of CKD on conservative treatment from nine Italian structures. Patients were enrolled applying different exclusion criteria, and various individual parameters were registered at the beginning for descriptive analysis. Patients were treated with epoetin alfa, beta, and darbepoetin as originator and epoetin zeta as biosimilar. Hemoglobin levels have been analyzed at baseline and after 3, 6, and 12 months. Descriptive statistics were used to analyze the results. RESULTS At baseline, 47 patients were in the biosimilar group and 57 in the originator; the basal level of hemoglobin was similar between the groups (mean Hb 9.4 and 9.3 g/dL, respectively). Median age, weight, and comorbidities were almost comparable. After 3 months, 44 patients remained in the biosimilar group and 48 in the originator; hemoglobin increase was significantly greater in patients treated with biosimilar [absolute increase 1.6 vs 1.0 g/dL, p < 0.001]. After 6 and 12 months, number of patients fall furthermore. Hemoglobin levels increased more in the biosimilar group after 6 months (2.1 vs 1.1 g/dL, p < 0.001) and 12 months (2.0 vs 1.0 g/dL, p < 0.001). CONCLUSIONS Biosimilar ESAs have similar risk/benefit profile compared to originators. Our data are in agreement with relevant scientific literature and, on the other hand, they are in contrast with common thought that considers biosimilar less efficacious and less safe than originators.

Abstract
BACKGROUND International guidelines recommend treatment of anaemia due to chronic kidney disease (CKD) with erythropoiesis-stimulating agents (ESAs). OBJECTIVE To document the time required and the cost in terms of nursing time to prepare and administer ESAs to patients on facility based haemodialysis (HD) with anaemia due to CKD before and after the introduction of long-acting ESAs. DESIGN A time and motion study was implemented at four HD units in Australia to determine the time and costs associated with preparing and administering ESAs before and after the introduction of long-acting ESAs. PARTICIPANTS This was a prospective, observational study of workplace practices at four HD units in Australia. MEASUREMENTS Outcome data included the time taken to prepare, and administer ESAs. RESULTS The time costs of preparation and administration per patient per year had a wide variability within each unit and ranged from Australian AUD$55.75 (38 euros) to AUD$90.49 (62 euros) before the introduction of long-acting ESAs. This dropped by 73-80% following the introduction of long-acting ESAs, representing an annual cost savings of between AUD$2,591 and AUD$5,914 if all patients on HD were switched to a long acting ESA. CONCLUSION Switching from a short-acting to a long-acting ESA in HD units leads to a significant reduction in time costs of health professionals in preparation and administration of ESAs by up to 80%. Practical application: This time and motion study has added further evidence on reduction of human effort by taking advantages of new research development, such as the long acting ESAs.

Abstract
AIMS The aim of this study was to evaluate the efficacy of levocarnitine injection for renal anemia in hemodialysis patients. METHODS In this randomized controlled clinical trial, we randomly assigned patients on maintenance hemodialysis at our hospital to receive levocarnitine injections (n = 30) or no injection (n = 30) and monitored the patients during 12 months of treatment. In the treatment group, patients received an injection of levocarnitine 1,000 mg 3 times weekly after hemodialysis sessions. All patients received recombinant human erythropoietin as an erythropoiesis-stimulating agent (ESA). Response to ESA therapy was determined by calculating the erythropoietin responsiveness index (ERI; ESA dose·kg-1·g-1· dL-1·week-1). RESULTS (1) The target levels of hemoglobin and hematocrit were maintained during the study period in both the levocarnitine group and the control group. (2) The dose of ESAs required to maintain these levels decreased gradually in the levocarnitine group and was significantly lower at 6 and 12 months than at study initiation. Furthermore, the dose of ESAs was significantly lower than that in the control group at 12 months. (3) The ERI showed a significant decrease at 6 and 12 months in the levocarnitine group, with a significant difference between the 2 groups at 12 months. CONCLUSION Our results suggest that levocarnitine administration can reduce the dose of ESAs required in patients with renal anemia on hemodialysis and improve the response to ESA therapy.

Abstract
Based on available literature and on the present review, IV iron administration to anemic cancer patients can increase significantly the level of Hb, probably independently from the precise mechanism of anemia itself. However, in future studies, the benefit should be evaluated taking into account whether the anemia is due to absolute or functional iron deficiency; therapeutic modalities might be different for these two conditions. Along the same lines, it appears important to further evaluate the respective roles of PO and IV iron therapies and the modalities of their use in clinical practice. Until the results of such studies are available, it appears reasonable to propose IV iron therapy to anemic cancer patients as the resulting rise of Hb level may increase their quality of life and performance status and reduce the need for erythropoietin-stimulating agents and/or blood transfusions.

Abstract
OBJECTIVE The aim of this study was to analyze the factors that are associated with the response to erythropoiesis-stimulating agents (ESAs) and its association with hospitalization and mortality rates; to evaluate the serum hepcidin level and its associations with iron profile, inflammatory markers, ESA responsiveness, and mortality; and to determine independent factors affecting ERI and hepcidin. MATERIALS AND METHODS To evaluate a dose-response effect of ESAs we used the erythropoietin resistance index (ERI). Patients were stratified in two groups: nonresponders and responders (ERI>15, n=20, and ERI ≤15U/kg/week/g per 100mL, n=153, respectively). Hematological data, hepcidin levels, iron parameters, inflammatory markers, hospitalization and mortality rates were compared between the groups. Multiple regression analysis was used to determine independent factors affecting ERI and hepcidin. RESULTS C-reactive protein (CRP) (β=0.078, P=0.007), albumin (β=-0.436, P=0.004), body mass index (β=-0.374, P<0.001), and hospitalization rate per year (β=3.017, P<0.001) were found to be significant determinants of ERI in maintenance hemodialysis (MHD) patients. Inadequate dialysis was associated with higher ERI. Patients with concomitant oncological diseases had higher ERI (31.2±12.4 vs 9.7±8.1U/kg/week/g per 100mL, P=0.002). The hepcidin level was 158.51±162.57 and 120.65±67.28ng/mL in nonresponders and responders, respectively (P=0.33). Hepcidin correlated directly with ERI, dose of ESAs, ferritin and inversely with Hb, transferrin saturation, and albumin. ERI (β=4.869, P=0.002) and ferritin (β=0.242, P=0.003) were found to be significant determinants of hepcidin in MHD patients. The hospitalization rate per year was 2.35±1.8 and 1.04±1.04 in nonresponders and responders, respectively (P=0.011). The mean length of one hospitalization was 25.12±21.26 and 10.82±17.25 days, respectively (P=0.012). Death occurred in 30% of the patients from the responders' group and in 50% from the nonresponders' group (P=0.289). The mean hepcidin concentration of patients who died was 141.9±129.62ng/mL and who survived, 132.98±109.27ng/mL (P=0.797). CONCLUSIONS CRP, albumin, BMI, and hospitalization rate per year were found to be significant determinants of ERI in MHD patients. Inadequate dialysis was associated with higher epoetin requirements. There were no difference in patient mortality by ERI, but a significant difference in hospitalization rates and mean length of one hospitalization was revealed. A significant positive relation between hepcidin and ERI was revealed. ERI and ferritin were found to be significant determinants of hepcidin in MHD patients. Hepcidin was not related to mortality.

Abstract
Purpose In the general population, haemoglobin (Hb) concentration is higher in men than in women. However, target Hb levels in dialysis patients are set constant regardless of the patient’s sex. The aim of this study was to evaluate Hb concentration and the use of erythropoiesis-stimulating agents (ESA) in peritoneal dialysis (PD) patients taking gender and dialysis adequacy into account. Methods The study comprised two parts. The first was a cross-sectional analysis of Hb and ESA in 2180 prevalent PD patients. The second included 88 incident PD patients, followed for 36 months. During this time, the major parameters recorded at 12-month intervals included: Hb concentration, weekly ESA, total, renal, and peritoneal Kt/V. Erythropoietin resistance index (ERI) was calculated as the ratio between ESA dose and achieved Hb. Results In prevalent PD patients, Hb concentration was significantly lower in women, (11.2 ± 1.4 vs. 11.5 ± 1.6 g/dl; p < 0.001), despite higher doses of ESA (2691 ± 1821 vs. 2344 ± 1422; p = 0.001). Hb concentrations were related to dialysis adequacy in both cohorts. However, despite significantly higher Kt/V, women were characterized by a lower Hb level. In incident patients, this association was present throughout the observation period, while the ESA dose in women was significantly higher at every time point. In multiple regression analysis, gender was an independent determinant of ERI (b = 0.34; p < 0.05). Conclusions Despite higher dialysis adequacy, Hb concentration in women treated with PD is significantly lower, and the ability to correct it impaired, as compared to men.

Abstract
BACKGROUND A number of policy and labeling interventions aimed at reducing inappropriate prescribing of erythropoiesis-stimulating agents (ESAs) were implemented in the U.S. between 2006 and 2010. These interventions included the addition of an FDA Black Box Warning to ESA labeling, the implementation of a Risk Evaluation and Mitigation Strategy program, and the adoption of payment restrictions by the Centers for Medicare and Medicaid Services (CMS). The impact of these safety interventions on different types of ESA prescribing (on-label, off-label; evidence-based, not evidence-based) has not been investigated in a single study. OBJECTIVES The objective of this study was to explore the prescribing patterns of ESAs for on- and off-label indications in the U.S. hospital inpatients during the period of major policy and labeling changes. METHODS A retrospective analysis of ESAs utilization patterns was conducted using Cerner Health Facts® database from January 1, 2005 to June 30, 2011. The study population consisted of adult patients admitted to hospitals during the study period who received at least one ESAs order. Indications for ESA use were assigned based on ICD-9 CM diagnosis codes, procedure codes, and medication records. ESA use was then classified based on FDA-approval and the strength of scientific evidence supporting its use. Indication categories included (1) on-label use (ONS); (2) off-label use, supported (OFS); and (3) off-label use, unsupported (OFU). Descriptive statistics were used to examine ESA use by patient, hospital, and physician characteristics and over time. RESULTS ESAs were most frequently prescribed for ONS (48.7%), followed by OFU (42.7%) and OFS indications (8.6%). Of all off-label use, 83.2% were for unsupported indications. Between 2005 and 2010, the percent of inpatient visits with ESA use decreased for supported indications, both on-label (-63.2%) and off-label (-78.2%), but increased for unsupported indications (80%). OFU use surpassed ONS use as the most common type of ESA use in 2009. CONCLUSIONS Total and ONS ESA use decreased markedly, while OFU ESA use continued to increase during the period of major policy and labeling changes.

Abstract
PURPOSE We systematically reviewed published observational studies and randomized controlled trials (RCT) reports of clinical trials on erythropoiesis-stimulating agents (ESA's). Only studies evaluating the risk of developing anti-drug antibodies (ADA) of both original and biosimilar drugs were chosen. METHODS Databases including PubMed, EMBASE and Cochrane Library were searched up to 17 March 2015. Two reviewers independently assessed the relevant studies for risk of bias. RESULTS Twenty-one publications were included. The overall prevalence of ADA in the studies was about 0.2 to 0.5 %. Most studies were not designed to monitor the development of ADA and often the study duration was too short (less than 6 months) and the patient population too small. Moreover, in many studies, the assays used only determined the presence of ADA and did not measure therapy failure due to ADA. In one RCT, as many as 13 cases (4 %) of ADA were identified. CONCLUSION ADA development seems to be low in short-term studies with ESA. None of the efficacy and safety issues for ESA biosimilars were judged to be adequately addressed in the evaluated literature, with respect to ADA formation, due to the study design and the assay method used.

Abstract
Background There is limited data showing that early treatment for anemia could prolong renal survival in non-dialysis chronic kidney disease (CKD) patients. We therefore investigated the relationship between hemoglobin (Hb) levels at initiation of epoetin beta therapy and renal outcome in non-dialysis CKD patients with anemia. Methods In this prospective, multi-center, observational study, non-dialysis CKD patients with anemia who were naïve to erythropoiesis-stimulating agents (ESAs) were divided into three groups based on their Hb levels at initiation of epoetin beta therapy (Group I: 10 ≤ Hb < 11 g/dL, Group II: 9 ≤ Hb < 10 g/dL, and Group III: Hb < 9 g/dL). The primary endpoint was time to first occurrence of any renal event. For the primary analysis, an inverse probability weighted Cox regression model was used to adjust time-dependent selection bias in the artificially censored data. Results A total of 1113 patients were eligible for primary endpoint analysis. Risk of renal events was significantly higher in Group III compared with Group I (HR, 2.52; 95 % CI, 1.98–3.21; P < 0.0001); although not significant, the risk was also higher in Group II compared with Group I (HR, 1.48; 95 % CI, 0.91–2.40; P = 0.11). Conclusion Initiation of ESA therapy when Hb levels decreased below 11 g/dL but not below 10 g/dL could be more effective at reducing the risk of renal events in non-dialysis CKD patients with anemia compared with initiation of ESA therapy at below 9 g/dL or even 10 g/dL.

Abstract
This meta-analysis was planned to define the role of erythropoiesis-stimulating agents (ESAs) in gynecological cancer patients, receiving myelosuppressive treatment. Pubmed, Medline and Scopus were searched to select English-language articles. Only randomized controlled trials (RCTs) were included. Endpoints were incidence of transfusions, thrombotic events (TE), deaths, and failures. Odd ratio (OR) with 95% confidence interval (CI) was calculated using fixed or random effects model. In seven RCTs ESAs studies of 892 patients under treatment, use of ESAs correlates with a significant reduction of transfusions rate (OR=0.35; 95% CI: 0.19-0.65; p=0.008). OR for overall mortality was 1.10 (95% CI 0.82-1.49; p=0.53). ESAs OR for disease failure in 5 studies was 1.71 (95% CI: 0.90-3.24; p=0.1). This meta-analysis, even if limited by few RCTs, suggests that ESAs reduce transfusions without increasing mortality or disease progression in gynecological cancer patients receiving treatment.

Abstract
Iron overload (IOL) portends inferior outcome in myelodysplastic syndromes (MDS). Erythropoiesis-stimulating agents (ESA) may reduce red blood cell transfusion requirements. MDS patients receiving ESA were reviewed for characteristics, response to ESA by International Working Group 2006 criteria and ferritin levels. Forty-nine patients received an ESA, had ferritin levels available, and were not receiving iron chelation therapy. Baseline characteristics were not significantly different between ESA responders (ER) and non-responders (ENR; P = NS). The median ESA treatment duration was 6.7 (1.5-85.9) months. Twenty-one (43 %) patients had an ESA response. Median ferritin level in ER was pre-ESA, 473 (range 91-2727) and post-ESA, 801 (130-11,164) ng/mL (P = 0.01), and in ENR pre-ESA, 672 (76-3285) and post-ESA, 1423 (431-6593) ng/mL (P < 0.0001). There was a significant association between ESA response, post-ESA hemoglobin ≥100 g/L, and post-ESA ferritin <1000 ng/mL (P = 0.0003 and 0.03, respectively). At a median follow-up of 28 months, the 2-year overall survival for ER and ENR, respectively, were 80 % and 86 % (P = NS). In lower-risk MDS patients responding to ESA, although an expected decrease in ferritin levels over treatment was not seen, ferritin levels increased less than in non-responders. Whether IOL may be reduced by ESA over a longer treatment duration may require analysis of larger numbers of patients.

Abstract
BACKGROUND Some data in literature indicate increased apoptosis of polymorphonuclear cells (PMNs) in chronic kidney disease (CKD), what seems to be connected with anemia. Erythropoiesis-stimulating agents, used in anemia treatment in CKD may affect cells apoptosis. Aim of this study was to investigate impact of anemia treatment with methoxy polyethylene glycol-epoetin beta (CERA) on PMNs apoptosis in predialysis patients with CKD. METHODS Percentage of early and late apoptotic PMNs was measured by flow cytometry based on annexin V and propidium iodide binding. CD90 (Fas), CD95L (FasL), CD16 and CD11b expression on PMNs were evaluated by flow cytometry after incubation with respective monoclonal antibody. RESULTS Percentage of PMNs in early and late apoptosis in CKD patients before CERA treatment was significantly higher to control group, which was accompanied by significantly higher Fas and Fas-L expression and significantly lower expression of CD16. CERA treatment downregulated significantly percentage of early, apoptotic PMNs but percentage of late apoptotic cells did not change and was still significantly higher to control group. In all investigated groups we observed a significant negative correlation between hemoglobin concentration and percentage of apoptotic PMNs, as well as Fas and FasL expression and significant positive correlation between Hb and CD16 expression. CONCLUSIONS Our results indicate that PMNs apoptosis is increased in predialysis patients with CKD and anemia treatment with CERA may diminish readiness of PMNs to undergo apoptosis. This antiapoptotic impact of anemia treatment with CERA seems to concern early apoptotic PMNs before they undergo to late, irreversible stage of apoptosis.

Abstract
Background Anemia is considered a negative prognostic risk factor for survival in patients with myelofibrosis. Most patients with myelofibrosis are anemic, and 35–54 % present with anemia at diagnosis. Ruxolitinib, a potent inhibitor of Janus kinase (JAK) 1 and JAK2, was associated with an overall survival benefit and improvements in splenomegaly and patient-reported outcomes in patients with myelofibrosis in the two phase 3 COMFORT studies. Consistent with the ruxolitinib mechanism of action, anemia was a frequently reported adverse event. In clinical practice, anemia is sometimes managed with erythropoiesis-stimulating agents (ESAs). This post hoc analysis evaluated the safety and efficacy of concomitant ruxolitinib and ESA administration in patients enrolled in COMFORT-II, an open-label, phase 3 study comparing the efficacy and safety of ruxolitinib with best available therapy for treatment of myelofibrosis. Patients were randomized (2:1) to receive ruxolitinib 15 or 20 mg twice daily or best available therapy. Spleen volume was assessed by magnetic resonance imaging or computed tomography scan. Results Thirteen of 146 ruxolitinib-treated patients had concomitant ESA administration (+ESA). The median exposure to ruxolitinib was 114 weeks in the +ESA group and 111 weeks in the overall ruxolitinib arm; the median ruxolitinib dose intensity was 33 mg/day for each group. Six weeks before the first ESA administration, 10 of the 13 patients had grade 3/4 hemoglobin abnormalities. These had improved to grade 2 in 7 of the 13 patients by 6 weeks after the first ESA administration. The rate of packed red blood cell transfusions per month within 12 weeks before and after first ESA administration remained the same in 1 patient, decreased in 2 patients, and increased in 3 patients; 7 patients remained transfusion independent. Reductions in splenomegaly were observed in 69 % of evaluable patients (9/13) following first ESA administration. Conclusions Concomitant use of an ESA with ruxolitinib was well tolerated and did not affect the efficacy of ruxolitinib. Further investigations evaluating the effects of ESAs to alleviate anemia in ruxolitinib-treated patients are warranted (ClinicalTrials.gov identifier, NCT00934544; July 6, 2009).

Abstract
Erythropoiesis-stimulating agents (ESAs) such as erythropoietin have been studied as red cell growth factors in preterm and term infants for more than 20 years. Recent studies have evaluated darbepoetin (Darbe, a long-acting ESA) for both erythropoietic effects and potential neuroprotection. We review clinical trials of Darbe in term and preterm infants, which have reported significant erythropoietic uses and neuroprotective effects. ESAs show great promise in decreasing or eliminating transfusions, and in preventing and treating brain injury in term and preterm infants.

Abstract
BACKGROUND The treatment of anemia in patients with cardiorenal syndrome (CRS) is based mainly on intravenous (IV) iron therapy and/or erythropoiesis-stimulating agents (ESAs). There are concerns about the safety of ESAs due to a potentially higher risk for stroke and malignancy. OBJECTIVE We aimed to explore whether IV iron alone is sufficient to improve anemia in CRS patients and to define the predictors of treatment response. METHODS We retrospectively analyzed data of 81 CRS patient treated for anemia at our clinic. All patients received IV iron for 6 weeks. A subset of patients was additionally given subcutaneous ESAs. The end point was the improvement from baseline in hemoglobin (Hb) and ferritin levels at week 7. RESULTS We retrieved the files of 81 patients; 34 received IV iron alone and 47 were given IV iron and ESAs (the combination group). The Hb levels significantly increased in both groups (in the IV iron alone group: 10.6 ± 1.1 to 11.9 ±1.1 g/dl, p < 0.001; in the combination group: 10.2 ± 0.9 to 12.4 ± 1.3 g/dl, p < 0.001), but more pronouncedly in the combination group (2.17 vs. 1.24 g/dl; p = 0.001). The platelet count decreased significantly in the IV iron alone group but was unchanged in the combination group. Eighty percent of patients attained a Hb target of 11 g/dl, with no significant difference between the two groups (73.5 vs. 85.1%; p = 0.197). Low baseline Hb was the only predictor of a favorable outcome to treatment. CONCLUSION Our observational study suggests that IV iron treatment without ESAs may substantially raise the Hb level to ≥11 g/dl in CRS patients. This treatment strategy may reduce the use of ESAs and hence its potential adverse effects.

Abstract
BACKGROUND AND OBJECTIVE The Anemia Working Group of ERBP in 2010 recommended a target hemoglobin (Hb) level in the range of 11-12 g/dL, without intentionally exceeding 13 g/dL during the treatment with erythropoiesis stimulating agents (ESAs). This study evaluated if there was a clinical impact of this statement in the anemia management of chronic kidney disease (CKD) patients treated with ESAs not on dialysis in routine clinical practice in Spain. METHODS This was an observational and cross-sectional study carried out in CKD patients not on dialysis in Spain who initiated ESA treatment (naïve), or were shifted from a previous ESA to another ESAs (converted) since January 2011. RESULTS Of 441 patients evaluated, 67.6% were naïve and 32.4% were converted. At the study visit, 42.5% of naïve patients achieved the Hb target of 11-12 g/dL, with a mean Hb of 11.3±1.3 g/dL (vs 10.1±0.9 g/dL at the start of ESA therapy). Only 35.3% of converted patients maintained Hb levels within the recommended target at the study visit. Yet, 8.2% of naïve patients and 7.9% of those converted had Hb levels >13 g/dL. Hb levels were similar across subgroups of patients, regardless of the presence of significant comorbidities. CONCLUSIONS Anemia management in CKD patients treated with ESAs by Spanish nephrologists seems to be aimed at preventing Hb levels <11 g/dL, while <50% of patients were within the narrow recommended Hb target range. This, together with the lack of individualization in Hb targets according to patients' comorbidities show that there is still room for improvement in renal anemia management in the clinical setting.

Abstract
INTRODUCTION Erythropoiesis-stimulating agents (ESAs) reduce red blood cell (RBC) transfusions in approximately 40% of patients with myelodysplastic syndrome (MDS) in clinical trials. We studied the association of timing of ESA initiation, agent (epoetin alfa, darbepoetin) and number of weeks of ESA use with response in MDS patients in routine practice. METHODS Patients diagnosed with MDS from 2001 to 2005 were identified in the Surveillance Epidemiology and End Results-Medicare linked database. The study cohort consisted of patients with new-onset transfusion dependence (TD). All patients received an ESA at least once during the study period, which began the week that criteria for TD were met and continued until transfusion independence (TI). Kaplan-Meier statistics and Cox Proportional Hazard models were used to assess relationships between time to ESA initiation, agent and number of weeks of ESA use and TI attainment. RESULTS Of 610 TD patients treated with ESAs, 210 (34.4%) achieved TI. Median time from ESA initiation to TI was 13 weeks. Shorter time from TD to ESA initiation and use of darbepoetin were associated with higher probability of achieving TI. The probability of achieving TI decreased beyond 8 weeks of treatment, and was very low beyond 16 weeks (8-15 weeks: HR=0.64, 16-31 weeks: HR=0.25, 32+ weeks HR=0.10). CONCLUSIONS In this observational, population-based study, variations in ESA administration impacted response in transfusion-dependent MDS patients, with higher response rates with early administration and use of darbepoetin, and low response likelihood in non-responders beyond 16 weeks of therapy.

Abstract
BACKGROUND Epoetin alfa (EPO) and darbepoetin alfa (DPO) are erythropoiesis-stimulating agents that are widely and interchangeably used for the treatment of anemia in patients with advanced chronic kidney disease and end-stage renal disease. No study has specifically compared the risks of hard study outcomes between EPO and DPO, including mortality. STUDY DESIGN Systematic review of the literature and meta-analysis. SETTING & POPULATION Patients enrolled in randomized trials comparing EPO versus DPO for the treatment of anemia in adults with chronic kidney disease, including those requiring dialysis. SELECTION CRITERIA FOR STUDIES We conducted a systematic search of the literature (PubMed, CENTRAL, SCOPUS, and EMBASE, all years) and industry resources, using predefined search terms and data abstraction tools. We then summarized key characteristics and findings of these trials and performed a random-effects meta-analysis of trials with at least 3 months' duration to identify the summary OR of mortality between patients randomly assigned to DPO versus EPO. INTERVENTION DPO versus EPO. OUTCOME All-cause mortality. RESULTS We identified 9 trials that met the stated inclusion criteria. Overall, 2,024 patients were included in the meta-analysis, of whom 126 died during follow-up, which ranged from 20 to 52 weeks. We found no significant difference in mortality between patients randomly assigned to DPO versus EPO (OR, 1.33; 95% CI, 0.88-2.01). No treatment heterogeneity across studies was detected (Q statistic=4.60; P=0.8). LIMITATIONS Generalizability to nontrial populations is uncertain. CONCLUSIONS Few trials directly comparing DPO and EPO have been conducted and follow-up was limited. In aggregate, no effect of specific erythropoiesis-stimulating agent on mortality was identified, but the confidence limits were wide and remained compatible with considerable harm from DPO. Absent adequately powered randomized trials, observational postmarketing comparative effectiveness studies comparing these erythropoiesis-stimulating agents are required to better characterize the long-term safety profiles of these agents.

Abstract
Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. It is diagnosed when serum iron concentrations are low despite adequate iron stores, as evidenced by serum ferritin that is not low. In the setting of inflammation, it may be difficult to differentiate AI from iron deficiency anemia, and the 2 conditions may coexist. Treatment should focus on the underlying disease. Recent advances in molecular understanding of AI are stimulating the development of new pathophysiologically targeted experimental therapies.

Abstract
After being a neglected and poorly-understood disorder for many years, there has been a recent explosion of data regarding the complex pathogenesis of myelodysplastic syndromes (MDS). On the therapeutic front, the approval of azacitidine, decitabine, and lenalidomide in the last decade was a major breakthrough. Nonetheless, the responses to these agents are limited and most patients progress within 2 years. Allogeneic stem cell transplantation remains the only potentially curative therapy, but it is associated with significant toxicity and limited efficacy. Lack or loss of response after standard therapies is associated with dismal outcomes. Many unanswered questions remain regarding the optimal use of current therapies including patient selection, response prediction, therapy sequencing and combinations, and management of resistance. It is hoped that the improved understanding of the underpinnings of the complex mechanisms of pathogenesis will be translated into novel therapeutic approaches and better prognostic/predictive tools that would facilitate accurate risk-adaptive therapy.

Abstract
Perioperative anemia is common in patients undergoing surgery and is associated with increased morbidity and mortality and a decreased quality of life. The main causes of anemia in the perioperative context are iron deficiency and chronic inflammation. Anemia can be aggravated by blood loss during surgery, and is most commonly treated with allogeneic transfusion. Moreover, blood transfusions are not without risks, once again increasing patient morbidity and mortality. Given these concerns, we propose to review the pathophysiology of anemia in the surgical environment, as well as its treatment through the consumption of iron-rich foods and by oral or intravenous iron therapy (iron sucrose and iron carboxymaltose). In chronic inflammatory anemia, we use erythropoiesis-stimulating agents (erythropoietin alpha) and, in cases of mixed anemia, the combination of both treatments. The objective is always to reduce the need for perioperative transfusions and speed the recovery from postoperative anemia, as well as decrease the patient morbidity and mortality rate.

Abstract
PURPOSE Anemia in cancer patients can be a result of the underlying cancer or related to treatment. Erythropoiesis-stimulating agents (ESAs) are an important option for many patients with chemotherapy-induced anemia, but are immersed in controversy. This article aims to reconcile conflicting opinions and provide expert guidance for appropriate ESA use. METHODS Teleconference, email, and a face-to-face meeting were used to assess ESA therapy "interpretive" data, which included two current meta-analyses, expert guidelines, and regulatory approved indications from Canada, Europe, and the USA. RESULTS Risks and benefits are associated with both red blood cell transfusions and ESA therapy, including improvements in hemoglobin levels and quality of life. ESAs have been associated with concerns regarding survival and progression of cancer, particularly when used in patients with cancer-related anemia. CONCLUSION Although safety concerns do exist, ESA therapy can be considered for use in patients with chemotherapy-induced anemia in accordance with Health Canada labeling.

Abstract
Objectives Little is known about erythropoiesis-stimulating agents (ESAs) utilization among lupus nephritis (LN) patients with incipient ESRD. We aimed to identify sociodemographic and clinical factors associated with ESA use among incident LN ESRD patients. Methods Among all individuals age ≥18 with incident ESRD from 1995-2008 in the U.S. Renal Data System (USRDS), we identified those with systemic lupus erythematosus (ICD-9 code 710.0) as the cause of ESRD. ESA use at ESRD onset was ascertained from the Medical Evidence Report. Year of onset, age, sex, race/ethnicity, medical insurance, employment status, residential region, clinical factors and comorbidities were considered potentially associated with ESA use in multivariable-adjusted logistic regression analyses. Results We identified 12,533 individuals with incident LN ESRD (1% of entire population). Of those, 4,288 (34%) received an ESA preceding ESRD. In multivariable-adjusted models, ESA users had higher serum albumin and hemoglobin concentrations, were more likely to be women, and to live in the Northeast. Conversely, Medicaid beneficiaries, the uninsured, unemployed, African Americans, Hispanics, and those with IV drug use, congestive heart failure and obesity had lower ESA use. Conclusion Among all U.S. patients and those with LN who developed ESRD, approximately one third received ESAs. Patient sex, race, age, medical insurance, residential region and clinical factors were significantly associated with ESA therapy. While there are no guidelines for ESA use in LN patients approaching ESRD, there has been wide sociodemographic variation, raising questions about ESA prescription practices.

Abstract
Anemia, already common in cancer patients, is often exacerbated by chemotherapy. Cancer patients who are anemic have been shown to have a blunted response for production of endogenous erythropoietin growth factor. This anemia can be corrected with exogenous erythropoietin growth factors, of which three available are worldwide: epoetin alfa, epoetin beta, and darbepoetin alfa. Collectively, these drugs are known as erythropoiesis-stimulating agents (ESAS). Orders for ESAS have been used not only to reverse anemia so as to avoid blood transfusion, but also to improve quality of life. Guidelines have been developed for initiation, dosage titration, and termination of these agents. Since the late 1990s, trials have been conducted using ESAS in unapproved dosing regimens or to reach hemoglobin levels outside of approved guidelines, raising several safety concerns. The present article explores the risks and benefits of ESAS.
