Darbepoetin alfa: review in the management of anemia in patients with chronic kidney disease

Chronic kidney disease (CKD) is a significant clinical problem across the world including India. The SEEK (Screening and Early Evaluation of Kidney Disease) study from India reported the prevalence of CKD as 17.2%. Diabetic nephropathy, undetermined etiology, chronic glomerulonephritis and hypertensive nephrosclerosis are the common causes of CKD in India. Rising rates of diabetes and hypertension, late presentation of patients to nephrologists and limited number of nephrologists in India adds to the concerns related to management of CKD. Considering the pathophysiology of CKD, anemia is almost an inevitable complication in these patients. Untreated anemia significantly contributes to the morbidity and mortality associated with CKD. Early recognition, timely management with appropriate therapy helps to reduce the complications of anemia. Erythropoiesis-stimulating agents (ESAs) are one of the important measures for correction of anemia in CKD patients. Darbepoetin, an ESA is a valuable therapeutic option for the treatment of anemia in CKD patients and has played a vital role in enhancing anemia management. In this article we reviewed the efficacy and safety data along with key benefits and place of darbepoetin alfa in the management of anemia in CKD patients.

Management of anemia in patients with congestive heart failure.

Anemia is an independent risk factor for adverse patient outcomes. There are no guidelines for management of anemia in patients with congestive heart failure (CHF), despite its high incidence. Four objectives were defined by the International Anemia Management and Clinical Outcomes Expert Panel (AMCO), a multinational group of interdisciplinary experts identified by the Society for the Advancement of Blood Management (SABM) to: determine the prevalence of anemia in outpatients; to determine the prevalence of hospital-acquired anemia; to assess the impact of anemia management on clinical outcomes such as quality of life and functional status; and to provide recommendations for primary care physicians and specialists for the diagnosis, evaluation, and management of anemia in patients with CHF. Anemia and iron deficiency were confirmed to be highly prevalent in patients with CHF. Intravenous iron therapy improves anemia, cardiac function and exercise tolerance, leading to improvement in quality of life. Anemia management has been demonstrated to be cost-effective. Clinical care pathways to manage anemia in patients with CHF are recommended as best practices in order to improve patient outcomes. Am. J. Hematol. 92:88-93, 2017. © 2016 Wiley Periodicals, Inc.

Hemoglobin levels and blood transfusion in patients with sepsis in Internal Medicine Departments.

BackgroundAcute reduction in hemoglobin levels is frequently seen during sepsis. Previous studies have focused on the management of anemia in patients with septic shock admitted to intensive care units (ICU’s), including aggressive blood transfusion aiming to enhance tissue oxygenation.AimTo study the changes in hemoglobin concentrations during the first week of sepsis in the setting of Internal Medicine (IM) units, and their correlation to survival.DesignObservational prospective study.MethodsWe recorded hemoglobin values upon admission and throughout the first week of hospital stay in a consecutive cohort of septic patients admitted to IM units at a community hospital, the patients were enrolled into a prospective registry.Data on blood transfusions was also collected, we examined the correlation between hemoglobin concentrations during the first week of sepsis and survival, the effect of blood transfusion was also assessed.ResultsEight hundred and fifteen patients (815) with sepsis were enrolled between February 2008 to January 2009. More than 20 % of them had hemoglobin levels less than 10g/dL on admission, a rate that was doubled during the first week of sepsis. Overall, 68 (8.3 %) received blood transfusions, 14 of them (20.6 %) due to bleeding. Typically, blood transfusion was given to older patients with a higher rate of malignancy and lower hemoglobin levels. While hemoglobin concentration on admission had strong correlation with in-hospital mortality (O.R-0.83 [95 % C.I. 0.74–0.92], blood transfusion was not found to be an independent predicting factor for mortality.ConclusionAnemia is very common in sepsis. While hemoglobin level on admission exhibit independent correlation with survival, blood transfusion do not.

Peginesatide for the treatment of anemia due to chronic kidney disease – an unfulfilled promise

ABSTRACTIntroduction: The introduction of recombinant human erythropoietin revolutionized the management of anemia in patients with chronic kidney disease (CKD). In order to circumvent costly recombinant DNA technology, synthetic chemistry techniques were used to manufacture peginesatide, a synthetic peptide that bore no resemblance to previous erythropoiesis-stimulating agents (ESAs), and yet was capable of stimulating erythropoiesis. Compared with other ESAs, peginesatide was deemed to have advantages related to immunogenicity, administration schedule, and cost. Marketing approval was restricted to CKD patients on dialysis because cardiovascular events were more common with peginesatide than with darbepoetin in non-dialysis CKD patients. Unfortunately, unexplained serious adverse drug reactions (sADR) led to quick withdrawal of peginesatide from the market.Areas covered: This review describes the efficacy and safety of peginesatide in pre-approval clinical trials, sADRs after marketing approval, and lessons learned during its short life-span.Expert opinion: The case of peginesatide illustrates the difficulties in detecting rare sADRs in trials with limited patient populations and the need for improved pharmacovigilance after marketing approval. However, the need for simpler drug production methods as a result of non-dependence on recombinant DNA techniques and mammalian cell lines remains. Lessons learned during the scientific development of peginesatide can be used in developing other drugs.

Anemia of Chronic Disease and Iron Deficiency Anemia in Inflammatory Bowel Diseases: Pathophysiology, Diagnosis, and Treatment.

Anemia coexists with inflammatory bowel disease (IBD) in up to two-thirds of patients, significantly impairing quality of life. The most common types of anemia in patients with IBD are iron deficiency anemia and anemia of chronic disease, which often overlap. In most cases, available laboratory tests allow successful diagnosis of iron deficiency, where difficulties appear, recently established indices such as soluble transferrin-ferritin ratio or percentage of hypochromic red cells are used. In this review, we discuss the management of the most common types of anemia in respect of the latest available data. Thus, we provide the mechanisms underlying pathophysiology of these entities; furthermore, we discuss the role of hepcidin in developing anemia in IBD. Next, we present the treatment options for each type of anemia and highlight the importance of individual choice of action. We also focus on newly developed intravenous iron preparations and novel, promising drug candidates targeting hepcidin. Concurrently, we talk about difficulties in differentiating between the true and functional iron deficiency, and discuss tools facilitating the process. Finally, we emphasize the importance of proper diagnosis and treatment of anemia in IBD. We conclude that management of anemia in patients with IBD is tricky, and appropriate screening of patients regarding anemia is substantial.

Abstract P1-10-02: Usage of epoetin alfa biosimilars in the management of chemotherapy-induced anemia in patients with breast cancer: A subanalysis of the ORHEO study

Abstract Introduction Chemotherapy-induced anemia (CIA) is a frequent complication of breast cancer patients that is associated with fatigue and impaired quality of life. Biosimilars of erythropoietin-stimulating agents have now been approved to treat CIA in Europe. The ORHEO (biOsimilaRs in the management of anaemia secondary to chemotherapy in HaEmatology and Oncology) study was an observational study conducted in France to evaluate the efficacy and safety of a biosimilar epoetin alfa in an oncology setting. The large number of patients who enrolled in the study permitted indication-specific subanalyses to be undertaken. Herein we report the results of the subanalysis that focuses on the subpopulation of breast cancer patients. Methods The ORHEO study was a prospective, observational, longitudinal, multicenter postmarketing study. Patients ≥18 years with CIA (hemoglobin [Hb] <11 g/dL)-associated solid tumors, lymphomas, or myelomas who were eligible for treatment with an epoetin alfa biosimilar were enrolled. The primary endpoint was Hb response (defined as Hb reaching ≥10 g/dL, an increase of Hb ≥1 g/dL since inclusion, or reaching target Hb) measured at 3 and 6 months (M3 and M6, respectively). Secondary endpoints included safety and tolerability. Only breast cancer patients with CIA were included in this subanalysis. Results The ORHEO study enrolled 2333 patients; of these, 266 patients presented with CIA associated with breast cancer and were included in this subanalysis. The mean age was 61 years, the majority had ECOG PS 1 (51.5%) and metastatic disease (56.0%), and 99.6% received an epoetin alfa biosimilar. At baseline, the mean Hb level was 9.9 g/dL. At the M3 and M6 time points, an Hb response was observed in 86.8% and 91.7% of patients, respectively; average Hb levels increased by 1.3 g/dL (M3) and 1.8 g/dL (M6). By M3, 44% of patients reached their target Hb level; this increased to 53.7% at M6. At M3 and M6, of those patients who definitively or temporarily discontinued treatment, over half did so because the target Hb had been reached (M3: 55.6% [n = 74/133]; M6: 53.2% [n = 81/152]). Clinically significant adverse events (AEs) were observed in 9.9% of patients; the most common AE was infection (7.9%), while thrombotic events were only reported in 0.8% of patients. High baseline systolic blood pressure, high hematocrit levels at M3, and clinical improvement by M3 were identified as potential indicators of a positive response to an epoetin alfa biosimilar. Conclusion This subanalysis of the large ORHEO observational study has demonstrated the utility of biosimilar epoetin alfa in a real-world setting. Biosimilar epoetin alfa was seen to be efficacious and well tolerated in patients with breast cancer who presented with CIA, and no new safety signals were identified in this subpopulation. These data support the results observed in the parent ORHEO study, and confirm that biosimilar epoetin alfa (Hospira) is a therapeutic alternative for treating CIA in patients with breast cancer. Several potential prognostic indicators were identified that may warrant further study. Citation Format: Albrand H, Luporsi E, Michallet M, Soubeyran P.

Novel iron-containing phosphate binders and anemia treatment in CKD: oral iron intake revisited.

Recent reports have shown that novel phosphate binders containing iron are not only efficacious for the treatment of hyperphosphatemia but also may reduce the need for erythropoiesis-stimulating agents and intravenous (IV) iron for anemia management in patients on maintenance hemodialysis (MHD). Possible healthcare cost savings, which have not been demonstrated in a long-term study, may be an additional advantage of using such multi-pronged treatment strategies for the control of both hyperphosphatemia and iron needs. It is currently assumed that oral iron supplementation is less efficient than the IV route in patients with chronic kidney disease (CKD). The unexpected efficacy of novel iron-containing phosphate binders, such as ferric citrate, in repleting insufficient iron stores and improving the anemia of CKD could change this view. Previous assumptions of self-controlled iron uptake by 'mucosal block' or hepcidin, or else by impaired intestinal iron absorption due to CKD-associated inflammation cannot be reconciled with recent observations of the effects of ferric citrate administration. Citrate in the intestinal lumen may partly contribute to the acceleration of iron absorption. Animal experiments and clinical studies have also shown that oral iron overload can cause excessive iron accumulation despite high hepcidin levels, which are not able to block iron absorption completely. However, like with IV iron agents, no long-term safety data exist with respect to the effects of iron-containing phosphate binders on 'hard' patient outcomes. Future randomized prospective studies in patients with CKD are necessary to establish the safety of oral iron-containing phosphate binders for the control of both hyperphosphatemia and renal anemia.

PWE-045 Management of anaemia in patients with inflammatory bowel disease: are we following the guidelines?

Introduction Anaemia is a common finding in patients with Inflammatory Bowel Disease (IBD). The British Society of Gastroenterology (BSG) has published a comprehensive set of guidelines for approaching this problem in patients with IBD in 2010. The aim of this audit was to evaluate current practice in screening and managing anaemia in IBD patients compared to BSG guidelines standards. Method IBD patients attending clinic and telephone clinics during a 2 week period in July and August 2014 at St. James’s University Hospital, Leeds were assessed retrospectively. Data collection included any haematological tests performed during the preceding year, investigations and therapy for anaemia. Results Monitoring for anaemia during the preceding year occurred in 119 of 122 (98%) eligible patients. 3 patients didn’t have haemoglobin checked annually (one of them due to non-compliance). Of the included 119 patients 56% were female with a median age of 41 years (range 18–80). 49% had a diagnosis of Crohn’s disease and 51% of ulcerative colitis. Anaemia was detected in 33 (24 females, 9 males, 17 Crohns disease, 16 ulcerative colitis) patients (28%). 6 females with anaemia were above the age of 50 and likely post menopausal. Anaemia was significantly more common in female patients (p = 0.038). 15 patients had microcytic hypochromic anaemia, but only 8 patients (53%) had appropriate Iron studies (Ferritin + CRP, followed by Iron + Transferrin saturation + TIBC if indicated) performed as per guidelines. Iron therapy was commenced orally in 4 cases and intravenously in 2 cases. 3 patients (37.5%) with confirmed Iron deficiency Anaemia (IDA) did not receive iron therapy. 5 patients had macrocytic anaemia. In 80% of these Vitamin B12 and folate were checked as per guidelines. Conclusion Anaemia occurs in a third of IBD patients. While monitoring for anaemia was achieved in 98% overall compliance with guidelines was suboptimal. Especially investigations and treatment for iron deficiency anaemia requires further improvement. An emphasis on managing anaemia in IBD patients should be encouraged and appropriate educational measures implemented. Local guidelines for managing anaemia in IBD with a checklist style proforma to be added to patients’ notes may improve adherence to recommendations. Disclosure of interest None Declared.

Overlooked Management and Risk Factors for Anemia in Patients with Intestinal Behçet's Disease in Actual Clinical Practice.

Background/AimsAnemia in patients with inflammatory bowel disease significantly affects the quality of life. The aim of this study was to investigate the frequency of and risk factors for anemia and to describe the management of anemia in patients with intestinal Behçet’s disease (BD) in actual clinical practice.MethodsWe included 64 patients with intestinal BD who visited the outpatient clinic of a tertiary referral center in June 2011 and had available laboratory data for the subsequent 6 months.ResultsAnemia was detected in 26 patients (40.6%). After 6 months, anemia was still present in 14 of these patients (53.8%). The cause of anemia was investigated in eight patients (30.8%), and oral iron supplementation was prescribed to four patients (15.4%). Of these four patients, two (50%) recovered completely within 6 months. Anemia was associated with a high Disease Activity Index for Intestinal Behçet’s Disease (DAIBD, p=0.024), erythrocyte sedimentation rate (p=0.003), and C-reactive protein (p=0.049) in univariate analysis. In multivariate analysis, the factor predictive for anemia in patients with intestinal BD was a higher DAIBD (≥40; odds ratio, 4.08; 95% confidence interval, 1.21 to 13.71; p=0.023).ConclusionsAlthough anemia is common in intestinal BD patients, its clinical importance is overlooked in daily practice. Moderate to severe disease activity is predictive of anemia.

Anemia in patients on chronic hemodialysis in Cameroon: prevalence, characteristics and management in low resources setting.

Anemia is a common complication of chronic kidney disease. We investigated the prevalence, characteristics and management of anemia in patients on chronic hemodialysis and assessed the response to blood-transfusion based management in Cameroon. This was a cohort study of five months' duration (August-December 2008) conducted at the Yaoundé General Hospital's hemodialysis center, involving 95 patients (67 men, 70.5%) on chronic hemodialysis by a native arteriovenous fistula. A monthly evaluation included full blood counts, number of pints of red cell concentrates transfused, and vital status. At baseline, 75 (79%) patients had anemia which was microcytic and hypochromic in 32 (43%). Anemia was corrected in 67 (70.5%) patients using blood transfusion only, while 28 (29.5%) patients were receiving erythropoietin (11 regularly, 39%). Only 77.2% of 342 pints (median 3.0, range 0-17 per patients) of red cell concentrates prescribed were effectively received during the follow-up at an unacceptably high cost to patients and families. Mean hemoglobin and mean corpuscular hemoglobin levels remained stable during follow-up, while mean corpuscular volume increased. Erythropoietin treatment was the main determinant of favorable trajectories of hematological markers. Patients on chronic hemodialysis have predominantly microcytic hypochromic anemia, with limited capacity for correction using blood transfusion.

PREPARE: the prevalence of perioperative anaemia and need for patient blood management in elective orthopaedic surgery: a multicentre, observational study.

Patient blood management (PBM) can prevent preoperative anaemia, but little is known about practice in Europe. To assess the pre and postoperative prevalence and perioperative management of anaemia in patients undergoing elective orthopaedic surgery in Europe. An observational study; data were collected from patient records via electronic case report forms. Seventeen centres in six European countries. Centres were stratified according to whether they had a PBM programme or not. One thousand five hundred and thirty-four patients undergoing major elective hip, knee or spine surgery [49.9% hip, 37.2% knee, 13.0% spine; age 64.0 years (range 18 to 80), 61.3% female]. Prevalence of preoperative (primary endpoint) and postoperative anaemia [haemoglobin (Hb) <13 g dl (male), Hb <12 g dl (female)], perioperative anaemia management, time to first blood transfusion and number of transfused units. Data are shown as mean (SD) or median (interquartile range). Anaemia prevalence increased from 14.1% preoperatively to 85.8% postoperatively. Mean Hb decrease was 1.9 (1.5) and 3.0 (1.3) g dl in preoperatively anaemic and nonanaemic patients, respectively (P < 0.001). In PBM (n = 7) vs. non-PBM centres, preoperative anaemia was less frequent (8.0 vs. 18.5%; P < 0.001) and iron status was assessed more frequently (ferritin 11.0 vs. 2.6%, transferrin saturation 11.0 vs. 0.1%; P < 0.001). Perioperative anaemia correction (mainly transfusion) was given to 34.3%. Intraoperatively, 14.8% of preoperatively anaemic and 2.8% of nonanaemic patients received transfusions [units per patient: 2.4 (1.5) and 2.2 (1.4), median time to first intraoperative transfusion: 130 (88, 158) vs. 179 (135, 256) min; P < 0.001]. Postoperative complications were more frequent in preoperatively anaemic vs. nonanaemic patients (36.9 vs. 22.2%; P = 0.009). Most patients who underwent elective orthopaedic surgery had normal preoperative Hb levels but became anaemic after the procedure. Those who were anaemic prior to surgery had an increased intraoperative transfusion risk and postoperative complication rate. PBM measures such as iron status assessment and strategies to avoid transfusion are still underused in Europe.

Management of anemia in patients with inflammatory bowel disease

Anemia is one of the commonest extraintestinal manifestations of inflammatory bowel disease (IBD). The pathogenesis of anemia in IBD is complex but iron deficiency combined with inflammation is the most common factor related to the development of anemia. However, other causes such as vitamin B12 and folate deficiency, hemolysis, myelosuppression and drug also should not be overlooked. In addition to ferritin, inflammatory markers and new biochemical parameters such as hepcidin and ferritin index are being tested as diagnostic a tool. First step for treatment is disease activity control and iron supplementation. Although oral iron is widely used, intravenous iron therapy should be considered in patients who are intolerant to oral iron therapy, have severe and refractory anemia or are in active disease state. Recently, new intravenous iron formulations have been introduced and due to their safety and easy usage, they have become the standard treatment modality for managing anemia in IBD. Erythropoietin and transfusion can be considered in specific situations. Vitamin B12 and folate supplementation is also important in patients who are deficient of these micronutrients. Since anemia in IBD patients could significantly influence the disease outcome, further studies and standard guideline for IBD are needed.

Helicobacter pylori infection and its association with anemia among adult dyspeptic patients attending Butajira Hospital, Ethiopia.

BackgroundHelicobacter pylori infection is associated with anemia. Understanding the magnitude of H.pylori infection and its association with anemia is important in the management of anemic patients. The aim of this study was to assess the association between H.pylori infection and anemia among dyspeptic patients.MethodsA cross-sectional study was conducted in Butajira Hospital, Southern Ethiopia among 401 systematically dyspeptic patients. A structured questionnaire was used to collected data about the patient characteristics. Blood samples were analyzed for red blood cell parameters. Stool samples were assessed for the presence of H.pylori antigens and the presence of intestinal helminthes. Data were summarized in frequencies (%) and mean (SD) as appropriate. Chi-square test, logistic regression and independent t-tests were used in the analysis as needed. In all cases P-value <0.05 was considered as statistically significant.ResultsThe overall prevalence of H. pylori infection was 52.4% and it was significantly associated with age, presence of intestinal parasites, smoking habit, alcohol drinking habit and body mass index. The prevalence of anemia among H.pylori infected patients (30.9%) was significantly (P < 0.001) higher than uninfected patients (22.5%). The mean (SD) values of HGB, MCV, MCH, MCHC, HCT and RBC count was significantly different between H.pylori infected and uninfected patients.ConclusionThis study showed high prevalence of H.pylori infection among dyspeptic patients and this was associated with age and some behavioral characteristics of the patients. H.pylori infected patients showed high rate of anemia prevalence as compared to their H.pylori unifected counter parts. From this study it can be recommended that intervention activities related to the behavioral characteristics and prevention of intestinal parasitic infections should be in place. The cross sectional nature of the study has a limitation to show cause and effect associations and hence association between H.pylori infections with anemia need to be investigated in cohort type studies.

Anaemia management in patients with chronic kidney disease: Taiwan practice guidelines.

The introduction of erythropoiesis-stimulating agents (ESAs) markedly improved the lives of many anaemic patients with chronic kidney disease (CKD). In Taiwan, the strategy of management of anaemia in patients with CKD was different from many other parts of the world. In 1996, the National Health Insurance Administration of Taiwan applied a more restrictive reimbursement criteria for ESA use in patients with CKD. ESA is to be initiated when non-dialysis CKD patients have a serum creatinine >6 mg/dL and a hematocrit <28% to maintain a hematocrit level not exceeding 30%. The maximal dose of epoetin-α or β was 20 000 U per month. The target haemoglobin range and dose limitation for ESAs were the same for dialysis CKD patients. Thus, long before randomized controlled trials showing an increased risk for cardiovascular events at nearly normal haemoglobin concentrations and higher ESA doses in CKD, nephrologists in Taiwan had avoided the use of disproportionately high dosages of ESAs to achieve a haemoglobin level of 10-11 g/dL. Moreover, intravenous iron supplementation was encouraged earlier in Taiwan in 1996, when we reached consensus on the diagnostic criteria for iron deficiency (serum ferritin <300 ng/mL and/or transferrin saturation <30%). The experience of CKD anaemia management in Taiwan demonstrated that a reasonable haemoglobin target can be achieved by using the lowest possible ESA dose and intravenous iron supplementation.

Safety and Efficacy of PDpoetin for Management of Anemia in Patients with end Stage Renal Disease on Maintenance Hemodialysis: Results from a Phase IV Clinical Trial.

Recombinant human erythropoietin (rHuEPO) is available for correcting anemia. PDpoetin, a new brand of rHuEPO, has been certified by Food and Drug Department of Ministry of Health and Medical Education of Iran for clinical use in patients with chronic kidney disease. We conducted this post-marketing survey to further evaluate the safety and efficacy of PDpoetin for management of anemia in patients on maintenance hemodialysis. Patients from 4 centers in Iran were enrolled for this multicenter, open-label, uncontrolled phase IV clinical trial. Changes in blood chemistry, hemoglobin and hematocrit levels, renal function, and other characteristics of the patients were recorded for 4 months; 501 of the patients recruited, completed this study. Mean age of the patients was 50.9 (±16.2) years. 48.7% of patients were female. Mean of the hemoglobin value in all of the 4 centers was 9.29 (±1.43) g/dL at beginning of the study and reached 10.96 (±2.23) g/dL after 4 months and showed significant increase overall (P<0.001). PDpoetin dose was stable at 50-100 U/kg thrice weekly. Hemorheologic disturbancesand changes in blood electrolytes was not observed. No case of immunological reactions to PDpoetin was observed. Our study, therefore, showed that PDpoetin has significantly raised the level of hemoglobin in the hemodialysis patients (about 1.7±0.6 g/dL). Anemia were successfully corrected in 49% of patients under study. Use of this biosimilar was shown to be safe and effective for the maintenance of hemoglobin in patients on maintenance hemodialysis.

Iron dosing in kidney disease: inconsistency of evidence and clinical practice.

The management of anemia in patients with chronic kidney disease (CKD) is difficult. The availability of erythropoiesis-stimulating agents (ESAs) has increased treatment options for previously transfusion-requiring patients, but the recent evidence of ESA side effects has prompted the search for complementary or alternative approaches. Next to ESA, parenteral iron supplementation is the second main form of anemia treatment. However, as of now, no systematic approach has been proposed to balance the concurrent administration of both agents according to individual patient's needs. Furthermore, the potential risks of excessive iron dosing remain a topic of controversy. How, when and whether to monitor CKD patients for potential iron overload remain to be elucidated. This review addresses the question of risk and benefit of iron administration in CKD, highlights the evidence supporting current practice, provides an overview of standard and potential new markers of iron status and outlines a new pharmacometric approach to physiologically compatible individualized dosing of ESA and iron in CKD patients.
