Abstract
Anemia is one of the most frequent extra-intestinal manifestations of inflammatory bowel disease. Insidious onset, variability of symptoms and lack of standardized screening practices may increase the risk of underestimating its burden in children with IBD. Despite its relevance and peculiarity in everyday clinical practice, this topic is only dealt with in a few documents specifically for the pediatric field. The aim of the current guidelines is therefore to provide pediatric gastroenterologists with a practical update to support the clinical and therapeutic management of children with IBD and anemia. A panel of 19 pediatric gastroenterologists and 1 pediatric hematologist with experience in the field of pediatric IBD was agreed by IBD Working group of the Italian Society of Gastroenterology, Hepatology and Nutrition (SIGENP) to produce the present article outlining practical clinical approaches to the pediatric patient with IBD and anemia. The levels of evidence and recommendations have been defined for each part of the statement according to the GRADE system.

Abstract
INTRODUCTION Anemia is a common complication of gastrointestinal (GI) disorders, with a prevalence up to 60% in celiac disease (CeD) and inflammatory bowel disease (IBD). Iron deficiency anemia (IDA) is the most prevalent form of anemia in these conditions, but chronic inflammation and vitamin B12 deficiency represent other common contributing mechanisms, especially in IBD. AREAS COVERED We discuss the pathogenesis of anemia in various medical GI disorders, the sometime problematic distinction between IDA, anemia of inflammation (AI) and the association of the two, and therapeutic and preventive measures that can be useful for the management of anemia in GI disorders. Unfortunately, with the exception of IDA and AI in IBD, large RCT concerning the treatment of anemia in GI disorders are lacking. EXPERT OPINION Anemia management strategies in GI disorders are outlined, with a focus on the main prevention, diagnostic, and therapeutic measures. Specific problems and situations such as the role of gluten-free diet for IDA treatment in CeD, the choice between oral and parenteral supplementation of iron or vitamin B12 in carential anemias, the use of endoscopic procedures to stop bleeding in intestinal angiodysplasia and preventive/treatment strategies for NSAID-associated GI bleeding are discussed.

Abstract
Immune-mediated disorders affecting the gastrointestinal (GI) tract may compromise GI integrity, interfere with the absorption of nutrients and cause bleeding and inflammation. All these features contribute to the pathogenesis of anaemia, the most prevalent extra-intestinal manifestation of immune-mediated GI disorders. Anaemia is most commonly due to iron deficiency and/or inflammation, but vitamin deficiencies and, more infrequently, autoimmune haemolysis or drug-induced myelosuppression can be involved. Here we address several issues related to the differential diagnosis and treatment of anaemia in immune-mediated GI disorders, giving particular relevance to the problem of iron deficiency anaemia associated with inflammation. It is emphasized how, in most cases, anaemias due to iron or vitamin deficiencies are best treated by parenteral administration of the deficient factor(s), and how the available high dose intravenous (IV) iron formulations can reduce ambulatory and social costs of IV iron supplementation, while improving patient's compliance to treatment. Actual and future treatment possibilities for anaemia of inflammation, involving the use of erythropoiesis stimulating agents, biologicals and hepcidin inhibitors are discussed.

Abstract
Iron deficiency or iron deficiency anemia (IDA) are some of the most common systemic complications of inflammatory bowel diseases (IBD). Symptoms such as fatigue, reduced ability to concentrate and reduced exercise tolerance can mimic common symptoms of IBD and can therefore easily be overseen. Furthermore, clinicians tend to see mild to moderate anemia as an inevitable accompaniment of IBD that is sufficiently explained by the underlying disease and does not require further workup. But in contrast to these clinical routines, current guidelines recommend that any degree of anemia in patients with IBD should be further evaluated and treated. Multiple studies have shown that anemia is a main factor for decreased quality of life (QoL) in patients with IBD. Correction of anemia, however, can significantly improve the QoL of patients with IBD. It is therefore recommended that every patient with IBD is regularly screened for iron deficiency and anemia. If detected, appropriate workup and treatment should be initiated. Over the last years, a number of new diagnostic tools and treatment options have been developed. Multiple studies have demonstrated the safety of newer formulations of intravenous iron in patients with IBD and have compared oral and intravenous iron in various situations. Treatment recommendations have changed and new evidence-based guidelines were developed. However, to date these guidelines are still not widely implemented in clinical practice. The aim of this review is to draw attention to the need for treatment for every level of anemia in patients with IBD and to provide some practical guidance for screening, diagnostics, treatment and follow up of IDA in patients with IBD following current international guidelines.

Abstract
PURPOSE OF REVIEW Anemia is the most common complication as well as an extra intestinal manifestation of inflammatory bowel disease (IBD). It is associated with a significant impact on patient's quality of life (QoL); as well it represents a common cause of frequent hospitalization, delay of hospital inpatient discharge and overall increased healthcare burden. In spite of all these, anemia is still often underdiagnosed and undertreated. Our aim in this review is to provide a pathway for physicians to help them achieve early diagnosis as well as timely and appropriate treatment of anemia which in turn would hopefully reduce the prevalence and subsequent complications of this condition among IBD patients. RECENT FINDINGS The etiology of anemia among IBD patients is most commonly due to iron deficiency anemia (IDA) followed by anemia of chronic disease. Despite this, more than a third of anemic ulcerative colitis (UC) patients are not tested for IDA and among those tested and diagnosed with IDA, a quarter are not treated with iron replacement therapy. A new algorithm has been validated to predict who will develop moderate to severe anemia at the time of UC diagnosis. While oral iron is effective for the treatment of mild iron deficiency-related anemia, the absorption of iron is influenced by chronic inflammatory states as a consequence of the presence of elevated levels of hepcidin. Also, it is important to recognize that ferritin is elevated in chronic inflammatory states and among patients with active IBD, ferritin levels less than 100 are considered to be diagnostic of iron deficiency. Newer formulations of intra-venous (IV) iron have a good safety profile and can be used for replenishment of iron stores and prevention of iron deficiency in the future. Routine screening for anemia is important among patients with IBD. The cornerstone for the accurate management of anemia in IBD patients lies in accurately diagnosing the type of anemia. All IBD patients with IDA should be considered appropriate for therapy with iron supplementation whereas IV administration of iron is recommended in patients with clinically active IBD, or for patients who are previously intolerant to oral iron, with hemoglobin levels below 10 g/dL, and in patients who need erythropoiesis-stimulating agents (ESAs). As the recurrence of anemia is common after resolution, the monitoring for recurrent anemia is equally important during the course of therapy.

Abstract
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
BACKGROUND The prevalence of inflammatory bowel disease (IBD) is increasing. Since patients usually need long-term treatment and suffer from reduced quality of life, there is a need to develop new therapeutic strategy. The aim of this study was to investigate the therapeutic potential of erythropoietin (EPO) for the treatment of IBD. METHODS Murine colitis was induced by 3.0% Dextran Sulfate Sodium (DSS). Recombinant human EPO (rhEPO) was given to evaluate the anti-inflammatory and regenerative effects on intestinal inflammation. The effect of rhEPO on human colon epithelial cells was also evaluated. Immunohistochemical analysis of EPO receptor was performed in human IBD tissues. RESULTS While about 62% of control mice with severe colitis induced by 5-day DSS died, 85% of mice treated with rhEPO survived. Histological analysis confirmed that EPO treatment reduced the colonic inflammation. Furthermore, EPO treatment significantly downregulated the local expressions of IFN-γ, TNF-α and E-selectin in the colon, suggesting that the effect was associated with inhibiting local immune activation. In a 4-day DSS-induced colitis model, rhEPO significantly improved the recovery of body weight loss compared to controls. Furthermore, proliferating cell nuclear antigen expression was significantly upregulated in the colon tissue from mice treated with rhEPO compared to controls. In addition, rhEPO increased the growth of cultured human colon epithelial cells in a dose-dependent manner. Furthermore, EPO-receptor expression was confirmed in human IBD colon tissues. CONCLUSION Three major functions of EPO, hematopoiesis, anti-inflammation and regeneration, may produce significant effects on intestinal inflammation, therefore suggesting that rhEPO might be useful for IBD.

Abstract
Anaemia is a common manifestation in inflammatory bowel disease (IBD) and impairs quality of life. Anaemia in IBD is typically caused by iron deficiency or anaemia of chronic disease. Treatment of iron deficiency with oral iron may lead to gastrointestinal intolerance though this may be related to the dose of iron replacement. New intravenous formulations have emerged which allow safe, rapid and effective correction of iron deficiency in IBD. In this article, we provide a review on the topic and cover recent progress in the field for the practicing gastroenterologist.

Abstract
Anemia, a common complication associated with inflammatory bowel disease (IBD), is frequently overlooked in the management of IBD patients. Unfortunately, it represents one of the major causes of both decreased quality of life and increased hospital admissions among this population. Anemia in IBD is pathogenically complex, with several factors contributing to its development. While iron deficiency is the most common cause, vitamin B12 and folic acid deficiencies, along with the effects of pro-inflammatory cytokines, hemolysis, drug therapies, and myelosuppression, have also been identified as the underlying etiology in a number of patients. Each of these etiological factors thus needs to be identified and corrected in order to effectively manage anemia in IBD. Because the diagnosis of anemia in IBD often presents a challenge, combinations of several hematimetric and biochemical parameters should be used. Recent studies underscore the importance of determining the ferritin index and hepcidin levels in order to distinguish between iron deficiency anemia, anemia due to chronic disease, or mixed anemia in IBD patients. With regard to treatment, the newly introduced intravenous iron formulations have several advantages over orally-administered iron compounds in treating iron deficiency in IBD. In special situations, erythropoietin supplementation and biological therapies should be considered. In conclusion, the management of anemia is a complex aspect of treating IBD patients, one that significantly influences the prognosis of the disease. As a consequence, its correction should be considered a specific, first-line therapeutic goal in the management of these patients.

Abstract
AIM OF THE STUDY To describe our 15-year experience on the patients' response and safety to the use of EPO in IBD patients with refractory anemia. PATIENTS-METHODS Single center retrospective chart analysis of all IBD patients receiving EPO for the period 1994-2009. Patients with resistant anemia not responding to I.V. iron therapy were enrolled. Concommitant medication, medical and laboratory data on short and long-term patients' responses and safety were recorded. RESULTS In total 820 IBD files were reviewed and among 78 patients treated with I.V. iron we identified 26 patients who received EPO in concordance to our inclusion criteria. Azathioprine or methotrexate was administered in 17 patients and 7 patients received concomitant Infliximab. After EPO, 22/26 patients (84.6%) responded and peripheral blood parameters were significantly improved and blood transfusions were significantly decreased (p<0.001). Erythropoietin dose was increased in three non-responders while two patients required emergency transfusions. No adverse events were recorded. CONCLUSIONS In anemic IBD patients who are refractory to I.V. iron monotherapy, administration of EPO significantly improved peripheral blood parameters with safety. Prospective controlled trials are needed to confirm positive patients' response to EPO and identify those patients who are more likely to benefit.

Abstract
The main types of anemia in inflammatory bowel disease (IBD) are iron deficiency anemia (IDA) and anemia of inflammatory etiology, or anemia of chronic disease (ACD). In the management of IBD patients with anemia it is essential for the physician to diagnose the type of anemia in order to decide in an evidence-based manner for the appropriate treatment. However, the assessment of iron status in IBD in many cases is rather difficult due to coexistent inflammation. For this assessment several indices and markers have been suggested. Ferritin, seems to play a central role in the definition and diagnosis of anemia in IBD and transferrin, transferrin saturation (Tsat), and soluble transferrin receptors are also valuable markers. All these biochemical markers have several limitations because they are not consistently reliable indices, since they are influenced by factors other than changes in iron balance. In this review, in addition to them, we discuss the newer alternative markers for iron status that may be useful when serum ferritin and Tsat are not sufficient. The iron metabolism regulators, hepcidin and prohepcidin, are still under investigation in IBD. Erythrocytes parameters like the red cell distribution width (RDW) and the percentage of hypochromic red cells as well as reticulocyte parameters such as hemoglobin concentration of reticulocytes, red blood cell size factor and reticulocyte distribution width could be useful markers for the evaluation of anemia in IBD.

Abstract
Anemia is the most prevalent extraintestinal complication of IBD. It can affect quality of life and ability to work, and can also increase the hospitalization rate in patients with IBD. Although the causes of anemia in IBD are multifactorial, iron deficiency anemia (IDA) is the most common. Assessment of the iron status of patients who have a condition associated with inflammation, such as IBD, by using common biochemical values is insufficient. However, new indices of iron metabolism (for instance ferritin:transferrin receptor ratio, reticulocyte hemoglobin content or percentage of hypochromic red blood cells) may help to improve the assessment of iron status in patients with IBD. The treatment of IDA traditionally involves oral iron supplementation. However, because of extensive gastrointestinal adverse effects, and data showing that the use of oral iron in IBD may be associated with disease exacerbation, current guidelines suggest that iron supplementation in IBD should be administered intravenously. This Review provides an overview of iron homeostasis in health before discussing diagnostic and therapeutic strategies for IDA in patients with IBD.

Abstract
BACKGROUND Intravenous iron has been suggested as a safe and effective treatment of anemia complicating inflammatory bowel disease (IBD). Low molecular weight (LMW) iron dextran has the ability to administer the patient's total iron requirement in a single infusion. AIMS The aim of this study was to assess the safety and efficacy of the total dose of LMW iron dextran infusion for the treatment of iron deficiency in IBD. METHODS Fifty IBD patients (27 female, 35 Crohn's disease, 15 ulcerative colitis) were included in the study. Mean +/- standard deviation (SD) hemoglobin and ferritin levels before the infusion were 9.88 +/- 1.42 g/dl and 13.9 +/- 10.9 ng/ml, respectively. A 25-mg test dose was followed by infusion of the total dose of LMW iron dextran based on the iron deficit. Several clinical and laboratory parameters were measured before and on week 4 after infusion. RESULTS Four patients (8%) developed adverse reactions during the test infusion and did not receive the total-dose infusion. Only one patient developed an allergic reaction during the total-dose infusion. In the remaining 45 patients, the mean +/- SD iron dose that was given was 1,075 +/- 269 mg. The mean +/- SD elevation of hematocrit and hemoglobin on week 4 was 4.9 +/- 1.9% and 1.7 +/- 0.8 g/dl, respectively. Hematopoietic response was observed in 23 of 45 patients (51.1%). CONCLUSION Total parenteral iron replacement with LMW iron dextran is an easy, safe, and effective alternative method for treating iron deficiency anemia in IBD. Harmless adverse reactions may develop in a minority of patients.

Abstract
Anemia is a significant problem in elderly patients. Although many anemic elderly patients can be diagnosed with nutritional deficiency, anemia of chronic inflammation or comorbid diseases that explain their decreased hematocrit, the etiology of anemia in a significant fraction remains obscure. There is evidence to suggest that the hematopoietic stem cell displays increasing erythropoietin (EPO) resistance with age. EPO levels rise in elderly, nonanemic patients, and it is hypothesized that there is an interplay between this rising demand for EPO and the decreasing ability of the aging kidney to produce adequate hormone to meet that need. There is further considerable evidence that aging is associated with increased proinflammatory cytokine expression and that many of these cytokines can contribute to EPO insensitivity. Consequently, genetic variation in the expression of these proinflammatory cytokines may influence the development of anemia in elderly patients, both through induction of hepcidin expression (anemia of inflammation) and through cytokine suppression of erythroid colony formation. The impact of inflammatory mediators, EPO insensitivity, and other factors that may act on the hematopoietic stem cell to decrease erythropoiesis are under active study and should serve to elucidate the pathophysiology of this important cause of morbidity and mortality in elderly individuals. A better understanding of the pathophysiology of anemia in elderly patients should provide critical entry points for interventions that will improve survival and quality of life in the aging population.

Abstract
Anemia is the most common complication of inflammatory bowel disease (IBD). Control and inadequate treatment leads to a worse quality of life and increased morbidity and hospitalization. Blood loss, and to a lesser extent, malabsorption of iron are the main causes of iron deficiency in IBD. There is also a variable component of anemia related to chronic inflammation. The anemia of chronic renal failure has been treated for many years with recombinant human erythropoietin (rHuEPO), which significantly improves quality of life and survival. Subsequently, rHuEPO has been used progressively in other conditions that occur with anemia of chronic processes such as cancer, rheumatoid arthritis or IBD, and anemia associated with the treatment of hepatitis C virus. Erythropoietic agents complete the range of available therapeutic options for treatment of anemia associated with IBD, which begins by treating the basis of the inflammatory disease, along with intravenous iron therapy as first choice. In cases of resistance to treatment with iron, combined therapy with erythropoietic agents aims to achieve near-normal levels of hemoglobin/hematocrit (11-12 g/dL). New formulations of intravenous iron (iron carboxymaltose) and the new generation of erythropoietic agents (darbepoetin and continuous erythropoietin receptor activator) will allow better dosing with the same efficacy and safety.

Abstract
Too often anemia is considered a rare or unimportant manifestation in inflammatory bowel disease (IBD). However, over the last 10 years a number of studies have been conducted and the most relevant conclusions obtained are: (1) anemia is quite common in IBD; (2) although in many cases anemia parallels the clinical activity of the disease, many patients in remission have anemia, and iron, vitamin B12 and/or folic acid deficiency; (3) anemia, and also iron deficiency without anemia, have important consequences in the clinical status and quality of life of the patient; (4) oral iron can lead to gastrointestinal intolerance and failure of treatment; (5) intravenous iron is an effective and safe way to treat iron deficiency; (6) erythropoietin is needed in a significant number of cases to achieve normal hemoglobin levels. Thus, the clinician caring for IBD patients should have a comprehensive knowledge of anemia, and apply recently published guidelines in clinical practice.

Abstract
OBJECTIVES Anemia is a common complication of inflammatory bowel disease (IBD) and iron deficiency (ID) is its predominant cause. Therefore, oral and intravenous iron replacements are widely used. This study was performed to evaluate the frequency and timing of anemia and ID recurrence after a successful treatment cycle. METHODS Medical records of patients who had received iron sucrose with or without erythropoietin (EPO) in one of three prospective clinical trials that had been conducted at our center (Ann Intern Med 1997, Digestion 1999, and Am J Gastroenterol 2001) were analyzed for a 5-year follow-up period. The risk for recurrence of anemia (hemoglobin (Hb)<12/13 g per 100 ml) and ID (ferritin <30 microg/l) was evaluated by Kaplan-Meier analysis using the log-rank test. RESULTS Eighty-eight patients were available for analysis. Patients had received a mean iron dose of 2,500 mg (range 600-3,600 mg); 33 (37.1%) patients had also received EPO. Anemia recurred in a median of 10 months (95% confidence interval (CI) 8-12) and ID recurred within 19 months (95% CI 11-28). The iron dose had no influence on recurrence of ID or anemia. ID (but not anemia) recurred faster in patients with a post-treatment ferritin level <100 microg/l (median 4 months, 95% CI 1-7) than in patients with ferritin level between 100 and 400 microg/l (median 11 months, 95% CI 6-16) and >400 microg/l (median 49 months, 95% CI 32-66; P<0.001). CONCLUSIONS IBD-associated ID and anemia recur surprisingly fast, indicating that maintenance treatment may be needed in a portion of the patient population. Recurrence of ID (but not anemia) can be delayed by aiming for high post-treatment ferritin levels.

Abstract
Anemia is the most common systemic complication of inflammatory bowel disease (IBD); so common that it is almost invariably not investigated and rarely treated. Several misconceptions are the reason for these clinical errors, and our goal will be to review them. The most common misconceptions are: anemia is uncommon in IBD; iron deficiency is also uncommon; just by treating the intestinal disease, anemia will be corrected; iron deficiency is the only cause for anemia in IBD; ferritin is an accurate parameter for the diagnosis of iron deficiency in IBD; the impact of anemia on the quality of life of IBD patients is limited; iron supplementation is rarely needed in IBD; high-dose oral iron solves the problem of iron malabsorption in IBD; intravenous (IV) iron is dangerous and of no proven benefit in IBD; IV iron is useful only for severe anemia; and erythropoietin has no role in the treatment of IBD anemia. These misconceptions are not evidence-based. On the contrary, there is enough evidence to support the following statements: (a) anemia is very common in IBD, (b) anemia should be investigated with care because many factors can be responsible, (c) treatment of anemia results in clear improvement in the objective parameters of well-being, especially in the quality of life, (d) IV iron is safe and effective in the treatment of iron deficiency anemia in IBD patients, and (e) erythropoietin is useful in a subset of patients with refractory anemia. Anemia diagnosis and treatment must not be neglected in IBD patients, and several misconceptions should be promptly abandoned.

Abstract
BACKGROUND AND AIMS Infliximab (IFX) and iron sucrose (FeS) are of high value in inflammatory bowel disease (IBD). We aimed to assess the relative role of both therapies in IBD related anaemia and their safety when used in combination. METHODS IBD patients with anaemia receiving a first series of FeS infusions in addition to IFX were prospectively followed. We investigated serum kinetics of erythropoietin (EPO), soluble transferrin receptors (sTFRs) and vascular endothelial growth factor (VEGF). RESULTS Data analysis included 87 patients of whom 49.4% achieved the target Hb level of 12.0 g/dL. IFX resulted in a significant increase of EPO and sTFR compared to baseline pre-IFX levels (p=0.029 and p=0.005 respectively) and after a 12-week combined FeS and IFX treatment, EPO and sTFR levels dropped significantly compared to pre-FeS levels (p<0.001 for both). Infusion related adverse events were recorded in 2 IFX treated patients (2.3%, 0.7% of the infusions) and were mild. Disease activity and quality of life were not affected. CONCLUSIONS In anaemic IBD patients treated with IFX, combined administration of FeS is safe. Infliximab significantly increases serum EPO and sTFR levels resulting in an increased functional iron deficiency, which is restored after combined treatment with I.V. iron sucrose.

Abstract
Anemia is a common complication of inflammatory bowel diseases. An international working party has formed and developed guidelines for evaluation and treatment of anemia and iron deficiency that should serve practicing gastroenterologists. Within a total of 16 statements, recommendations are made regarding diagnostic measures to screen for iron- and other anemia-related deficiencies regarding the triggers for medical intervention, treatment goals, and appropriate therapies. Anemia is a common cause of hospitalization, prevents physicians from discharging hospitalized patients, and is one of the most frequent comorbid conditions in patients with inflammatory bowel disease. It therefore needs appropriate attention and specific care.

Anemia is a frequent complication in patients with inflammatory bowel disease (IBD), and is associated with decreased quality of life and increased rate of hospitalization. The primary therapeutic targets of IBD-associated anemia are iron deficiency and anemia of chronic disease. An important prognostic parameter of the success or failure of therapy is the outcome of the underlying disease. Iron deficiency should be appropriately managed with iron supplementation. However, the use of oral iron therapy is limited by several problems, the most important being gastrointestinal side effects leading occasionally to disease relapse and poor iron absorption. Intravenous iron preparations are more reliable, with iron sucrose demonstrating the best efficacy and tolerability. Treatment with erythropoietin or darbepoetin has been proven to be effective in patients with anemia, who fail to respond to intravenous iron. Patients with ongoing inflammation have anemia of chronic disease and may require combination therapy comprising of intravenous iron sucrose and erythropoietin. After initiating treatment, careful monitoring of hemoglobin levels and iron parameters is needed in order to avoid recurrence of anemia. In conclusion, anemia in the setting of IBD should be aggressively diagnosed, investigated, and treated. Future studies should define the optimal dose and schedule of intravenous iron supplementation and appropriate erythropoietin therapy in these patients.

Abstract
BACKGROUND Anaemia is a serious complication of Crohn's disease that triggers hospitalization and, if not interfered with, may lead to death. AIMS To systematically summarize and compare the literature on anaemia in Crohn's disease. METHODS For this systematic review the literature was searched for English-language articles using anaemia, Crohn* and IBD as key words. 144 articles were identified and sorted according to the following topics: prevalence, aetiology, diagnostic tests and therapy. RESULTS The reported prevalence of anaemia varied between 6.2% and 73.7%, with higher reported frequencies in older studies and in in-patients. Iron deficiency is the most common underlying condition. Vitamin B12 deficiency is related to the extent of ileal resection but has rarely impact on anaemia. Diagnostic criteria are not established and treatment guidelines are missing. Oral iron supplementation seems effective for short periods but intolerance leads to discontinuation in up to 21%. Eleven of 11 studies show that oral iron enhances intestinal inflammation and colon carcinogenesis in animal models of colitis. Intravenous iron supplementation with iron sucrose has been tested in over 250 Crohn's disease patients, is safe, effective and does not carry such hazards. CONCLUSIONS As disease activity is determining the degree of anaemia in Crohn's disease, implementation of more effective therapy for Crohn's disease will lower its incidence. However, further studies regarding the safety and effectiveness of iron supplementation are needed.
