The advantages of intravenous renal anaemia treatment in an undernourished patient with chronic kidney disease

The subcutaneous (SC) treatment of renal anaemia in undernourished patients has potential limitations. In this case report we demonstrate the value of intravenous (IV) darbepoetin alfa in such a patient who experienced difficulty tolerating SC recombinant human erythropoietin (rHuEPO) therapy due to severe malnutrition. Intravenous treatment of renal anaemia in a malnourished patient is preferred because the absence of SC fat makes SC administration difficult. In such patients, darbepoetin alfa is the treatment of choice as it is administered less frequently than other erythropoietic therapies and is more effective at maintaining target haemoglobin (Hb) concentrations. In contrast to rHuEPO, darbepoetin alfa also has the additional advantage of bioequivalent IV and SC dose requirements.

Achieving therapeutic targets in renal anaemia: considering cost-efficacy

SUMMARY

Erythropoietin treatment for anaemia in chronic kidney disease (CKD) brings important clinical benefits, but restricted healthcare budgets necessitate value-for-money therapies, requiring economic considerations also to be taken into account when selecting a treatment regimen. Subcutaneous (SC) administration of epoetin is effective at a lower dose than intravenous (IV) administration, offering the potential for substantial reductions in costs of treatment. Unlike epoetin alfa, which is contra-indicated by the SC route in Europe in patients with CKD, epoetin beta (NeoRecormon*) can be safely and effectively given by either route. The multidose presentations of epoetin beta (Reco-Pen?, multidose vials) may provide further opportunity for dose reduction. The tolerability of SC epoetin beta is excellent and superior compared with epoetin alfa or darbepoetin alfa. Epoetin beta given once weekly is as effective as two- or three-times weekly, and the dosing frequency can be further reduced to once every 2^?weeks in patients who are stable on once-weekly dosing. Reduced dosing frequency is more convenient for the patient and may save nursing time in dialysis units. Overall, SC epoetin beta, compared with alternative treatments, may represent a cost-effective treatment option for anaemia management as it combines a well-established safety and efficacy record, favourable local tolerability, and the convenience of once-weekly dosing with the potential to reduce treatment costs by up to 30%.     

Improved haemoglobin concentrations with IV darbepoetin alfa--case studies of haemodialysis patients

Over 5 years of darbepoetin alfa: two case histories

Anaemia is one of the most serious complications of renal dysfunction and is associated with severe, often life-threatening clinical sequelae including cardiovascular disease [1]. Anaemia of renal insufficiency originates from a reduced ability of the kidney to produce the protein hormone erythropoietin (EPO), which is responsible for the initiation of red blood cell (RBC) production from precursor cells produced by the bone marrow. Currently, European Best Practice Guidelines for the Management of Anaemia in Patients with Chronic Renal Failure recommend that treatment of renal anaemia should be achieved by the supplementation of endogenous EPO with recombinant human EPO (rHuEPO), which stimulates erythropoiesis, thereby inducing a rise in haemoglobin (Hb) concentrations [2]. Usually, rHuEPO therapy is given two or three times per week and can be administered by the intravenous or subcutaneous routes in patients undergoing haemodialysis (HD) or subcutaneously in patients receiving peritoneal dialysis (PD). Darbepoetin alfa (Aranesp^®, Amgen, Inc.) is an erythropoiesis-stimulating protein that is molecularly distinct from rHuEPO. It is super-sialated, which leads to a longer serum half-life than that of rHuEPO [3,4], resulting in extended in vivo erythropoietic activity. Darbepoetin alfa can be given less frequently and can be used subcutaneously or intravenously with the same, or equivalent Hb responses and dosing [7], offering simplified dosing for new patients and those currently treated with rHuEPO. Clinical trials with darbepoetin alfa began in 1997 and this brief article reports on two patients whose long-term anaemia management has been simplified by its use.

Análisis probabilístico de minimización de costes de darbepoetin alfa frente a epoetina alfa en el tratamiento de la anemia secundaria a insuficiencia renal crónica. Valoración en la práctica clínica española

IntroductionThe direct transfer of the results of pharmaco-economic studies between countries may not be suitable if the proper adaptations are not made to take into account differences in treatment patterns, resource use and costs from country to country.ObjectiveTo estimate the cost in Spain of treating anaemia secondary to chronic renal failure with darbepoetin alpha or epoetin alpha from a review and analysis of available current information. In addition, the role of the route of administration as a main driver of the cost will be analysed.MethodPopulation: patients with chronic kidney failure induced anaemia. Data: Medline and Embase search of studies directly comparing erythropoiesis stimulating agents. Analysis: Cost minimization analysis from the perspective of a hospital pharmacy department. The main outcome chosen was the difference between the average cost per patient undergoing a 30-day treatment with epoetin alpha versus darbepoetin alpha.Resultsa) haemodialysis: changing from epoetin alpha to darbepoetin alpha is associated with a cost reduction of 8.67 %; CI 95 %, ?1.34 to 17.92 (€ 17.48; CI 95 %, ?2.70 to 36.13); probabilistic analysis showed that the use of darbepoetin alpha could be associated with a cost-saving probability of 94.9 %. The IV administration yielded a decrease in costs of about 16.00 %; CI 95 %, ?2.38 to 36.77 (€ 41.78, CI 95 %: ?6.21 to 96.04). b) Pre-dialysis: darbepoetin alpha is associated with a cost reduction of about 11-32 %.ConclusionsThe use of darbepoetin alpha for the treatment of chronic renal failure induced anaemia (haemodialysis and pre-dialysis) shows higher cost efficiency than epoetin alpha in Spain; these differences increase with IV administration.     

Pharmacokinetics of darbepoetin alfa after intravenous or subcutaneous administration in patients with non-myeloid malignancies undergoing chemotherapy

BACKGROUND AND OBJECTIVE: The pharmacokinetics of darbepoetin alfa after intravenous (IV) administration in the oncology setting have not been previously reported. The objective of this study was to evaluate the pharmacokinetics of IV or subcutaneous (SC) darbepoetin alfa in patients with non-myeloid malignancies undergoing multicycle chemotherapy.

Darbepoetin alfa: a review of its use in the treatment of anaemia in patients with cancer receiving chemotherapy

Darbepoetin alfa (Aranesp) is an analogue of recombinant human erythropoietin (rHuEPO) produced using recombinant DNA technology. The high number of sialic acid moieties in darbepoetin alfa results in a prolonged half-life and enhanced in vivo biological activity compared with rHuEPO (as demonstrated in animal studies) and permits a reduction in the frequency of administration.Subcutaneous darbepoetin alfa 2.25 microg/kg once weekly or 500 microg once every 3 weeks (with a provision for dose adjustments) is an effective and well tolerated erythropoietic agent in anaemic patients with cancer receiving chemotherapy. In randomised, controlled clinical trials, the drug increased haemoglobin levels and reduced the need for blood transfusions in patients with various types of nonmyeloid malignancies and also ameliorated anaemia-related fatigue, thereby improving their health-related quality of life (HR-QOL) scores. The once-every-3-weeks dosage regimen provides further convenience by offering the possibility of synchronising its administration with most chemotherapy regimens. Direct comparisons between approved dosages of darbepoetin alfa and other erythropoietic agents have not been conducted. Such comparisons would be very helpful in formulating definitive conclusions about their relative efficacy and cost effectiveness. Darbepoetin alfa provides an effective and well tolerated treatment option for the treatment of anaemia in patients with cancer receiving chemotherapy.     

Darbepoetin alfa.

Darbepoetin alfa is a novel erythropoiesis-stimulating protein developed for the treatment of anaemia associated with chronic kidney disease. In single-dose studies in patients undergoing dialysis, the mean terminal half-life for intravenous darbepoetin alfa was approximately 3-fold longer than for intravenous recombinant human erythropoitin (r-HuEPO, epoetin alfa; 25.3 vs 8.5 hours). The mean terminal half-life after subcutaneous administration of darbepoetin alfa was 48.8 hours. In randomised nonblind trials in patients undergoing dialysis, darbepoetin alfa (0.45 pg/kg) given once weekly for the correction of anaemia increased haemoglobin (Hb) levels to a similar extent as darbepoetin alfa three times weekly or r-HuEPO two or three times weekly. A double-blind, randomised clinical trial reported that switching patients from a three-times weekly regimen of r-HuEPO to once weekly darbepoetin alfa with additional placebo twice weekly (all intravenously) maintained Hb levels between 9.0 and 13.0 g/dl to a similar extent as continued treatment with r-HuEPO three times weekly. In a randomised nonblind study, r-HuEPO-naive patients with chronic renal insufficiency received either subcutaneous darbepoetin alfa once weekly or r-HuEPO twice weekly. 93% of patients receiving darbepoetin alfa and 92% of patients receiving r-HuEPO achieved a Hb increase of > or = 1.0 g/dl from baseline and the mean increase in Hb level over the initial 4 weeks was similar for both treatments. The number and frequency of adverse events, withdrawals and deaths reported in clinical trials did not differ between patients receiving darbepoetin alfa and patients receiving r-HuEPO. There have been no reports of immune responses to darbepoetin alfa in 1534 patients receiving treatment for up to 2 years.     

Darbepoetin alfa: in patients with chemotherapy-related anaemia

Darbepoetin alfa, novel erythropoiesis stimulating protein closely related to human erythropoietin, has been developed for the treatment of chemotherapy-related anaemia in patients with non-myeloid malignancies. In three 12-week, phase II studies in patients with cancer and chemotherapy-related anaemia, subcutaneous darbepoetin alfa, administered in once-weekly or 2-, 3- or 4-weekly regimens, dose-dependently increased the mean haemoglobin levels. In a randomised, double-blind, phase III study in 320 patients with lung cancer and chemotherapy-related anaemia, recipients of subcutaneous darbepoetin alfa 2.25 micro g/kg once weekly, received red blood cell (RBC) transfusion approximate, equals 2-fold less frequently than placebo recipients (p < 0.001). In the same study, patients receiving darbepoetin alfa also received fewer standard units of RBC for transfusion and had greater haematopoietic response rate than placebo recipients (both p < 0.001). Subcutaneous darbepoetin alfa 2.25 micro g/kg once weekly also reduced patient-reported fatigue (assessed by a quality-of-life questionnaire) [p = 0.019 vs placebo]. black triangle Darbepoetin alfa was generally well tolerated in clinical trials. The most frequent darbepoetin alfa-related adverse events were: body oedema, arthralgia and skin rash.     

Darbepoetin alfa: new indication/new dosage. No proven advantage in chemotherapy-induced anaemia

(1) Current treatments for anaemia in patients receiving cancer chemotherapy include blood transfusion and epoetin alfa and beta. These epoetins correct anaemia in 40% to 65% of patients and reduce the number of patients who require transfusions during the second and third months of treatment by 12-35% in absolute terms. (2) Darbepoetin alfa is slightly more glycosylated than epoetin alfa and beta. It is no more effective than these two drugs in chronic renal failure. Darbepoetin alfa is now approved for the treatment of anaemia in patients who are receiving chemotherapy for non myeloid malignancies. (3) Two placebo-controlled dose-finding studies and two placebo-controlled trials involving nearly 1000 patients in total have shown that darbepoetin alfa decreases the number of transfused patients by 17-25% in absolute terms, and that it probably reduces fatigue. However, one-quarter of patients receiving darbepoetin were nonetheless transfused. (4) In the absence of reliable comparisons, there is no firm evidence that darbepoetin alfa is more effective than other epoetins. (5) According to relatively imprecise company reports, darbepoetin alfa increased the risk of thromboembolic events during clinical trials (6% versus 3%), including pulmonary embolism (1.3% versus 0%); the company also states that darbepoetin alfa does not increase the risk of arterial hypertension, a classical effect of epoetin that is mentioned in the summary of product characteristics (SPC). Placebo-controlled trials and dose-finding studies show no impact on the outcome of cancer, but follow-up is limited and a negative effect cannot be ruled out. The company states that no cases of erythroblastopenia have occurred among more than 70 000 treated patients. (6) According to the SPC, darbepoetin alfa can be given once a week. However, the optimal epoetin dosing schedule is unknown. Epoetin therapy takes several weeks to correct anaemia, whereas transfusion is immediately effective. (7) In practice, darbepoetin alfa seems a little easier to administer than epoetin alfa or beta, but the advantages and disadvantages of these drugs as compared with blood transfusion are not entirely clear.     

Subcutaneous injection pain with C.E.R.A., a continuous erythropoietin receptor activator,compared with darbepoetin alfa

ABSTRACT

Objective: This study assessed injection site pain following subcutaneous (SC) administration with a continuous erythropoietin receptor activator (C.E.R.A.), compared with darbepoetin alfa in healthy adults.

Methods: In a randomized, placebo-controlled, single-centre, single-blind, three-way crossover study, subjects received one of six treatment sequences (ABC/ACB/BAC/BCA/CBA/CAB) involving SC injection of (A) C.E.R.A. 50?μg, (B) darbepoetin alfa 50?μg, or (C) placebo on days 1, 29, and 57. An initial pilot phase (n = 12) was used to determine the sample size for the confirmatory phase (n = 72), and data were combined for the final analysis (n = 84).

Main outcome measures: The primary endpoint was pain on the 100?mm visual analog scale (VAS) immediately after dosing. Secondary endpoints included VAS at 1 hour after dosing and pain on the six-point verbal rating scale (VRS) immediately and at 1 hour after dosing.

Results: C.E.R.A. was associated with significantly less pain immediately after SC injection compared with darbepoetin alfa: least squares mean VAS 21.5 (95% confidence interval [CI]: 17.5, 25.5) versus 33.4 (95% CI: 28.4, 38.4) (?p < 0.0001). Incidence of pain on the VRS was lower with C.E.R.A. compared with darbepoetin alfa immediately after dosing (?p < 0.0001). One hour after administration, most subjects had no VRS pain. A study limitation is the small sample size and the findings need to be confirmed in a large trial of chronic kidney disease patients.

Conclusions: SC injection with C.E.R.A. is significantly less painful than SC darbepoetin alfa in healthy adults. Treatment of anemia in chronic kidney disease with SC injection of C.E.R.A. may provide a lower pain burden compared with darbepoetin alfa.     

A randomised,cross-over study comparing injection site pain with subcutaneous epoetin beta and subcutaneous darbepoetin alfa in patients with chronic kidney disease*

ABSTRACT

Objective: To compare injection site pain of subcutaneous (sc) epoetin beta and darbepoetin alfa in adult patients with chronic kidney disease.

Research design and methods: This was a multi-centre, randomised, two-arm, single-blind, cross-over study. Patients were randomised to receive weekly sc darbepoetin alfa 30?μg or weekly sc epoetin beta 6000?IU for 2 weeks and were then crossed over to the alternative treatment for 2 weeks. Injection site pain was assessed using a 10?cm ungraduated visual analogue scale (0?=?no pain, 10?=?worst pain) and a six-point verbal rating scale. Patient preference for treatment was also assessed.

Trial registration: http://clinicaltrials.gov/(NCT00377481).

Results: All randomised patients (N?=?48) completed the study. The sample comprised 29 chronic kidney disease patients (Stage 3 or Stage 4), 11 peritoneal dialysis patients and 8 renal transplant patients. Patients perceived significantly less pain with epoetin beta than darbepoetin alfa, using the visual analogue scale (relative pain score?=?2.75, darbepoetin alfa:epoetin beta, 95% CI: 1.85, 4.07; p?<?0.0001) and the verbal rating scale (median: 0.5, 95% CI: 0.5, 1.0 vs. median: 1.5, 95% CI: 1.0, 2.0; p?<?0.0001). Epoetin beta was preferred by significantly more patients (65%) than darbepoetin alfa (10%) (p?<?0.001); 25% of patients reported no preference.

Conclusions: Limitations included lack of an epoetin alfa comparator and limited blinding (patients were blinded to treatment, however, an unblinded nurse administered treatment). We show that sc injection of epoetin beta is significantly less painful than darbepoetin alfa and patient preference for epoetin beta confirms that the difference is clinically meaningful.     

Preference for monthly darbepoetin alfa dosing in patients with chronic kidney disease not receiving dialysis

ABSTRACT

Objective: To determine patient preference for once-weekly Epoetin alfa versus once-monthly (QM) darbepoetin alfa in patients with chronic kidney disease (CKD) not receiving dialysis.

Methods: AMPS (Aranesp Monthly Preference Study) consisted of two studies of similar design, each with a 2-week screening/baseline period, a 20-week QM darbepoetin alfa dosing period, and an 8-week follow-up period. Patients aged ≥18 years had a nephrologist-reported diagnosis of CKD but were not receiving dialysis, and were required to have at least two hemoglobin levels within 10–12?g/dL and to have been receiving a stable dose (< 25% change) of once-weekly or once- every-other-weekly Epoetin alfa for at least 8 weeks. At week 21, patients could continue on QM darbepoetin alfa or revert back to their previous Epoetin alfa regimen. The primary analysis assessed patient preference at week 21 for QM darbepoetin alfa versus previous onceweekly Epoetin alfa.

Results: AMPS enrolled 442 patients: 54% were female, 67% were Caucasian, and mean (SD) age was 68.3 (13.5) years. At week 21, 346 patients remained on study. Of the patients converted from once-weekly Epoetin alfa, 86% (138/161) preferred darbepoetin alfa QM, and of all patients who expressed a preference, regardless of previous Epoetin alfa dosing frequency, 96% (305/319) preferred QM darbepoetin alfa. Mean (SD) hemoglobin at week 29 of the study was similar to mean hemoglobin at baseline (for those who completed the study and were receiving QM darbepoetin alfa at week 29: 11.2 [1.1]?g/dL at week 29 versus 11.4 [0.7]?g/dL at baseline). QM darbepoetin alfa was well tolerated.

Conclusion: These data show that the majority of study patients preferred QM darbepoetin alfa to more frequent Epoetin alfa, and that QM darbepoetin alfa maintained hemoglobin levels at week 29 and was well tolerated over the study period. The single-item questionnaire could be a potential limitation of this study and further investigation with a multi-question instrument may be helpful in confirming these results.     

Epoetins and [symbol: see text] darbepoetin alfa in malignant disease

Anaemia is common in people with cancer, and may reduce their quality of life and life expectancy. Blood transfusion can increase haemoglobin levels but is usually reserved for those with moderate anaemia (haemoglobin level below 10 g/dL). A potential alternative is treatment with one of the human recombinant forms of erythropoietin, epoetin alfa (Eprex--Janssen-Cilag) or epoetin beta (NeoRecormon--Roche), or their hyperglycosylated derivative [symbol: see text] darbepoetin alfa (Aranesp--Amgen). These products have improved the management of patients with chronic renal failure who are anaemic. Here we assess the place of the epoetins and darbepoetin alfa in managing anaemia in patients with cancer.     

The relative dosing of epoetin alfa and darbepoetin alfa in chronic kidney disease

ABSTRACT

Objective: The purpose of this study was to review and analyze current research to evaluate the dose ratio of epoetin alfa and darbepoetin alfa for the treatment of anemia in chronic kidney disease (CKD) and to identify determinants of the variation in epoetin alfa: darbepoetin alfa dose ratios across studies.

Methods: A systematic review of the literature for comparative switch and non-switch studies of epoetin alfa and darbepoetin alfa treatments in CKD for the period 2000–2005 was performed. Two reviewers independently assessed the quality of the information. Data on the study design and outcomes were collected for each selected study. The dose ratio from epoetin alfa to darbepoetin alfa was calculated for each study, and the results were reported stratified by study characteristics. To control for differences in study design and characteristics that could explain the variability in the relative dosages of the two agents across studies, multivariate regression analysis was conducted. Based on these results, a dose conversion ratio for Canada was estimated.

Results: A total of 21 studies involving 16?378 patients exposed to epoetin alfa or darbepoetin alfa in CKD were identified. Univariate analysis of the dose ratios indicated a mean dose ratio of 217:1 (IU of epoetin alfa:µg of darbepoetin alfa). Results from the multivariate analysis demonstrated that the study design (i.e., switch study versus straight comparison studies) and geographical coverage (i.e., United States) affected the results. Based on the multivariate analysis, the dose conversion ratio between epoetin alfa and darbepoetin alfa for Canada was 169:1.

Conclusions: Despite limitations associated with switching studies and the limited total number of studies available, this systematic review based on aggregated results provides further evidence to the clinical community that the dose conversion ratio for epoetin alfa:darbepoetin alfa in CKD patients in Canada is approximately 169:1. At that ratio, treatment with epoetin alfa is 11–18% cheaper than treatment with darbepoetin alfa in Canada.     

Management of anaemia: a critical and systematic review of the cost effectiveness of erythropoiesis-stimulating agents

Erythropoiesis-stimulating agents (ESAs) are genetically engineered forms of erythropoietin that are used in the treatment of anaemia. Their successful use in the treatment of anaemia associated with renal disease, cancer and other diseases, as well as the development of multiple agents, has increased the visibility of these agents in the clinical and health economics literature. The circumstances under which the use of ESAs is cost effective, or indeed, whether it is cost effective, is of central concern for clinicians and payers who must make informed decisions regarding the management of these costly resources. Much of the recent literature on ESAs in the treatment of anaemia associated with chronic kidney disease and cancer, the two major therapeutic areas for ESA treatment, has focused on comparisons between individual ESAs, particularly epoetin alfa and darbepoetin alfa. While there have been some studies of cost effectiveness, many studies in these treatment areas have employed a cost-minimization approach and have relied on published prices rather than actual market prices. In general, this review of the literature suggests a cost advantage for epoetin alfa relative to darbepoetin alfa in the treatment of anaemia in renal and oncology indications. For other indications in which the literature is less developed, such as anaemia induced by antiviral therapy and blood management in surgery, small prospective studies or decision-analytic models comparing ESA therapy and standard care have been most common. Few conclusions can be drawn about the overall and relative costs or cost effectiveness of ESAs in these treatment areas.With the recent concerns about the safety of ESAs, especially when used outside the approved product labelling, future evaluations of epoetin alfa and darbepoetin alfa should factor their safety profiles into estimates of cost effectiveness. Moreover, additional studies are needed to evaluate whether the treatment of anaemia with ESAs is cost effective compared with no treatment or minimal blood transfusions, and whether the cost effectiveness of ESAs would be improved if ESA doses and durations were reduced.With the introduction of new longer-acting ESAs, such as the continuous erythropoietin receptor activator, the relative cost effectiveness among the different ESAs will continue to be an important question for public and private payers, policy makers and clinicians who must consider the emergence of new data and changing dosing patterns when making decisions about the use of these important but costly agents.     

Guidelines and recommendations for the management of anaemia in patients with lymphoid malignancies

Patients with lymphoid malignancies frequently require repetitive and intensive anticancer treatments to induce and maintain disease remission. Anaemia (haemoglobin [Hb] <12 g/dL) is a common and debilitating problem associated with both the malignancy itself and its treatment burden. Anaemia negatively impacts on all aspects of patient quality of life (QOL) and treatment outcomes and survival, particularly in this disease setting.Widely acknowledged goals of anaemia treatment include Hb correction to approximately 12 g/dL, reduction in transfusion requirements and optimisation of patient QOL. Since the introduction of recombinant human erythropoietic therapy, transfusion (once the only anaemia treatment option available) is now primarily reserved for non-responders or those with severe or life-threatening anaemia. Data from randomised, double-blind, placebo-controlled studies, and large, non-randomised, open-label, community-based studies, along with almost 15 years of practical experience, support the assertion that epoetin alfa administered at a dosage of 150-300 U/kg three times weekly or 40,000-60,000U once weekly, both of which are US FDA-approved dose administration schedules, can effectively and safely achieve anaemia treatment goals for the majority of patients with lymphoid malignancies. Data and practical experience collected over the last 5 years on another erythropoietic agent with a slightly longer half-life but lower binding affinity, darbepoetin alfa, show that this agent when administered according to the FDA-approved dose administration schedules (2.25-4.5 microg/kg once weekly or 500microg once every 3 weeks) or according to a commonly-administered dose in clinical practice (3.0-5.0 microg/kg once every 2 weeks) can also effectively and safely correct anaemia, reduce transfusion requirements and improve QOL in many patients with lymphoid malignancies. One comparative head-to-head trial suggested that epoetin alfa might be superior to darbepoetin alfa in anaemic cancer patients receiving chemotherapy with respect to timing and magnitude of Hb correction, although further study is necessary, especially concerning optimal dose administration. Alternative dose administration schedules, such as epoetin alfa 80,000U every 2 weeks from initiation or 80,000U every 3 weeks following initiation with once weekly administration and darbepoetin alfa 4.5 microg/kg every 3 weeks following initiation with once weekly administration, are being actively investigated with the goal of increased flexibility for patients and healthcare providers.The treatment of anaemia in patients with lymphoid malignancies is an important part of overall disease management, as evidenced by continuous investigation of existing erythropoietic agents and new agents. Although treatment guidelines issued by organisations such as the National Comprehensive Cancer Network (NCCN) and American Society of Hematology (ASH)/American Society of Clinical Oncology (ASCO) suggest intervention with erythropoietic therapy when Hb falls below 10-11 g/dL or based on clinical symptoms, data suggest that anaemia is vastly under-recognised and under-treated. Clearly, an update on the definition, identification and optimal management of anaemia in patients with lymphoid malignancies is warranted.
