Anaemia affects roughly a third of the world's population; half the cases are due to iron deficiency. It is a major and global public health problem that affects maternal and child mortality, physical performance, and referral to health-care professionals. Children aged 0-5 years, women of childbearing age, and pregnant women are particularly at risk. Several chronic diseases are frequently associated with iron deficiency anaemia--notably chronic kidney disease, chronic heart failure, cancer, and inflammatory bowel disease...

Anemia is a common complication in patients with chronic kidney disease (CKD), mainly due to inadequate renal production of erythropoietin. In hemodialysis (HD) patients this condition may be aggravated by iron deficiency (absolute or functional). The correction of this anemia is usually achieved by treatment with erythropoiesis stimulating agents (ESAs) and iron (oral or intravenous). Studies questioning the safety of ESAs (especially at higher doses) changed the pattern of anemia treatment in CKD patients...

Deirdre Hahn, June D Cody, Elisabeth M Hodson
BACKGROUND: The benefits of erythropoiesis-stimulating agents (ESA) for dialysis patients have been demonstrated. However, it remains unclear whether the efficacy and safety of new, longer-acting ESA given less frequently is equivalent to recombinant human erythropoietin (rHuEPO) preparations. This is an update of a review first published in 2002 and last updated in 2005. OBJECTIVES: This review aimed to establish the optimal frequency of ESA administration in terms of effectiveness (correction of anaemia, and freedom from adverse events) and efficiency (optimal resource use) of different ESA dose regimens...

BACKGROUND: Intravenous iron use in hemodialysis patients has greatly increased over the last decade, despite limited studies on the safety of iron. METHODS: We studied the association of receipt of intravenous iron with hospitalizations in an incident cohort of hemodialysis patients. We examined 9544 patients from Dialysis Clinic, Inc. (DCI). We ascertained intravenous iron use from DCI electronic medical record and USRDS data files, and hospitalizations through Medicare claims...

Anemia is a common feature of CKD associated with poor outcomes. The current management of patients with anemia in CKD is controversial, with recent clinical trials demonstrating increased morbidity and mortality related to erythropoiesis stimulating agents. Here, we examine recent insights into the molecular mechanisms underlying anemia of CKD. These insights hold promise for the development of new diagnostic tests and therapies that directly target the pathophysiologic processes underlying this form of anemia...

BACKGROUND: The elderly hemodialyzed population is growing. However, little is known about the relationship between hemoglobin level and survival according to age. We investigated the effect of age on the relationship between hemoglobin and survival within the Japan Dialysis Outcomes and Practice Patterns Study (DOPPS) cohort. METHODS: We enrolled the entire Japan DOPPS phases 3 and 4 population. Patients were divided by the age of 75 years into two groups. Cox's proportional hazard model was used with hemoglobin at every 4 months treated as a time-dependent variable...

BACKGROUND: Endogenous erythropoietin is increased in patients with heart failure (HF). Previous small-scale data suggest that these erythropoietin levels are related to prognosis. This study aims to analyze the clinical and prognostic value of erythropoietin levels in relation to hemoglobin in a large cohort of HF patients. METHODS AND RESULTS: In patients hospitalized for HF, endogenous erythropoietin levels were measured at discharge and after 6 months. In anemic patients, the relation between erythropoietin and hemoglobin levels was determined by calculating the observed/predicted ratio of erythropoietin levels...

AIMS: Over half of chronic heart failure (CHF) patients are anaemic, and iron deficiency is common. Iron replacement therapy (oral or i.v.) might improve exercise capacity and quality of life (QOL). METHODS AND RESULTS: We carried out a systematic review and meta-analysis of all randomized control trials that compared iron with no therapy for CHF patients with iron deficiency, whether or not they were anaemic. We searched electronic databases as well as haematology and cardiology conferences up to August 2011...

Heart failure and kidney disease often coexist, and each of the two conditions may lead to progression of the other. Kidney dysfunction is an independent prognostic factor in patients with either acute or chronic heart failure. Worsening renal function may be related with poorer outcomes as well. Multiple mechanisms are involved in the cardio-renal interaction, including hemodynamic abnormalities, neurohormonal and inflammatory activation, oxidative stress, anemia, and abnormalities in mineral and vitamin D metabolism...

RANDOMIZED CONTROLLED TRIAL
I H Kraai, M L A Luttik, P Johansson, R M De Jong, D J Van Veldhuisen, H L Hillege, T Jaarsma
BACKGROUND: Anemia is a serious and highly prevalent co-morbidity in chronic heart failure (HF) patients. Its influence on health-related quality of life (HR-QoL) has rarely been studied, and no data is available regarding the role it plays in hospitalized HF patients. METHODS: Baseline data from the COACH study (Coordinating study evaluating Outcomes of Advising and Counselling in Heart Failure) were used. HR-QoL was assessed by means of generic and disease-specific questionnaires...

REVIEW
W H Wilson Tang
Anemia is commonly observed in patients with heart failure, and portends worsening functional capacity and poorer long-term prognosis. Nevertheless, uncertainty remains regarding the underlying pathophysiology and natural history of anemia in the setting of chronic heart failure. The optimal therapeutic targets and treatment options for this "anemia of heart failure" are also uncertain. Careful evaluation of potential underlying reversible causes, particularly renal insufficiency and iron or nutritional deficiencies, may lead to potential treatment options...

BACKGROUND: Anemia in heart failure patients and has been associated with increased morbi-mortality. Previous studies have treated anemia in heart failure patients with either erythropoietin alone or combination of erythropoietin and intravenous (i.v.) iron. However, the effect of i.v. or oral (p.o.) iron supplementation alone in heart failure patients with anemia was virtually unknown. AIM: To compare, in a double-blind design, the effects of i.v. iron versus p...

AIMS: Suicidal death of erythrocytes (eryptosis) is characterized by cell shrinkage and exposure of phosphatidylserine (PS) residues at the cell surface. Excessive eryptosis may lead to anaemia. We aimed to study the role of eryptosis in heart failure (HF)-associated anaemia. METHODS AND RESULTS: We measured eryptosis in rodent models of HF. Typical measures of eryptosis including PS-exposure, increased intracellular Ca(2+) levels, and decreased cell volume were determined by flow cytometry...

REVIEW

Anemia has been identified as an independent prognostic factor of both morbidity and mortality for patients with congestive heart failure (CHF). The association between anemia and adverse outcomes has raised the hypothesis that anemia correction might lead to an improvement in the prognosis of patients with CHF. Nevertheless, data from large randomized trials about the effect of anemia correction on patient outcome are still lacking. Numerous clinical studies, randomized and nonrandomized, have evaluated the efficacy of erythropoietin or iron supplementation for treating anemia in patients with CHF, and their effect on patient symptoms and functional status...
