Abstract
Gastrointestinal (GI) bleeding is associated with considerable morbidity and mortality. Red blood cell (RBC) transfusion has long been the cornerstone of treatment for anemia due to GI bleeding. However, blood is not devoid of potential adverse effects, and it is also a precious resource, with limited supplies in blood banks. Nowadays, all patients should benefit from a patient blood management (PBM) program that aims to minimize blood loss, optimize hematopoiesis (mainly by using iron replacement therapy), maximize tolerance of anemia, and avoid unnecessary transfusions. Integration of PBM into healthcare management reduces patient mortality and morbidity and supports a restrictive RBC transfusion approach by reducing transfusion rates. The European Commission has outlined strategies to support hospitals with the implementation of PBM, but it is vital that these initiatives are translated into clinical practice. To help optimize management of anemia and iron deficiency in adults with acute or chronic GI bleeding, we developed a protocol under the auspices of the Spanish Association of Gastroenterology, in collaboration with healthcare professionals from 16 hospitals across Spain, including expert advice from different specialties involved in PBM strategies, such as internal medicine physicians, intensive care specialists, and hematologists. Recommendations include how to identify patients who have anemia (or iron deficiency) requiring oral/intravenous iron replacement therapy and/or RBC transfusion (using a restrictive approach to transfusion), and transfusing RBC units 1 unit at a time, with assessment of patients after each given unit (i.e., “don’t give two without review”). The advantages and limitations of oral versus intravenous iron and guidance on the safe and effective use of intravenous iron are also described. Implementation of a PBM strategy and clinical decision-making support, including early treatment of anemia with iron supplementation in patients with GI bleeding, may improve patient outcomes and lower hospital costs.

Abstract
This study aimed to investigate whether serum indicators related to iron stores in the body are associated with clinical and endoscopic disease severity. Eighty-four patients with Crohn’s disease (CD) and twenty-four healthy volunteers were included. The indicators related to iron stores were detected within one week after endoscopic and CT enterography examinations. Patients were divided into three groups according to the CDAI(Crohn's disease activity index)scores. Serum iron levels were decreased in all groups (p < 0.05), and the values of remission group were higher than those of moderate group (p < 0.001). The total iron binding capacity(TIBC)values of the moderate group were lower than those of the controls and the other groups (p < 0.05). None of the indicators differed significantly among the patients classified by SES-CD (p > 0.05). Underweight, decreased serum iron and TIBC were independent risk factors for moderate clinical disease. Combined detection of decreased serum iron and TIBC was helpful in differentiating severe patients. The sensitivity and specificity were 32.7% and 100%, respectively (AUC = 0.812, p < 0.01). Decreases in serum iron and TIBC were associated with the clinical activity of CD. Combined detection of the two indicators was conducive to screening serious disease.

Abstract
BACKGROUND Iron deficiency (ID) is a frequent condition in patients with inflammatory bowel disease (IBD). AIM Our aim was to investigate the prevalence of ID in patients with IBD. METHODS This was a prospective multicenter cross-sectional study conducted in 21 gastroenterology departments in France between January and March 2020. All adult patients with confirmed IBD who were admitted to the hospital were eligible for inclusion. ID was defined as ferritinemia ≤ 100 μg/L in patients with signs of inflammation (C-reactive protein (CRP) ≥ 5 mg/L) or ferritinemia < 30 μg/L in the absence of inflammation. RESULTS In total, 1036 IBD (685 Crohn's disease and 351 ulcerative colitis) patients (52.1% women) with a mean age of 41.8 ± 15.5 years were recruited. Approximately half of the patients (504, 51.1%) were in disease remission at the time of enrollment. Systematic monitoring of iron status was performed in 12/21 (57%) participating centers, including measurements of ferritin (12/12, 100%), hemoglobin (11/12, 92%), transferrin saturation (TSAT) (6/12, 50.0%), and serum iron (5/12, 42%). About one-fifth of the patients had been treated with intravenous iron (218, 21.0%), whereas only a small percentage received oral iron (36, 3.5%). ID occurred in 97 patients (23.7% CI 95% 19.8-28.1). Patients with moderate/severe IBD activity (OR: 3.66; CI 95% 24.4-61.2; p = 0.007) or concomitant anemia (OR: 3.66; CI 95% 1.97-6.78; p < 0.001) had an increased likelihood of having ID. CONCLUSION Patients with moderate/severe IBD activity or concomitant anemia are at increased risk of ID. Early detection and management of ID in patients with IBD is recommended.

Abstract
PURPOSE OF REVIEW This article reviews iron deficiency anemia (IDA) and suspected small bowel bleeding (SSBB) from initial consultation through laboratory evaluation, endoscopic evaluation, and therapeutic options. RECENT FINDINGS Recent guidelines on management of SSBB, IDA, video capsule endoscopy (VCE), and device-assisted enteroscopy (DAE) are reviewed. The advantages and limitations of VCE, DAE, and imaging are discussed. Medical treatment for refractory small bowel bleeding is discussed. Evaluation of IDA starts with a detailed history and physical exam. Additional lab work can establish the diagnosis of IDA and evaluate for associated conditions. If initial endoscopic tests are unrevealing, SSBB should be ruled out. Further investigation can be performed using video capsule endoscopy (VCE), device-assisted enteroscopy (DAE), and imaging. The mainstay of medical treatment of IDA secondary to SSBB is iron supplementation. Additional treatment is tailored to the pathology and may include medical, endoscopic and surgical options.

Abstract
ABSTRACT BACKGROUND: Data regarding the prevalence of anemia in inflammatory bowel disease (IBD) patients are scarce in Brazil. Anemia and iron deficiency anemia have been known to cause significant functional impairment, lower quality of life, and higher morbidity and mortality and may be correlated with an impact on the cost of treatment. OBJECTIVE: The aim of this study was to estimate the prevalence and risk factors for anemia and iron deficiency anemia in patients with IBD in a tertiary IBD unit in Southeast Brazil. METHODS: We conducted an Institutional Review Board-approved retrospective analysis of an adult IBD cohort (IBD Unit, Ribeirão Preto Medical School, University of São Paulo, Brazil) consisting of 579 patients between January 2014 and July 2018. Clinicoepidemiological data, hemoglobin measurements and serum ferritin were extracted from electronic medical records. Anemia prevalence was calculated among ulcerative colitis (UC) and Crohn’s disease (CD) phenotypes. Risk factors for anemia were also calculated. RESULTS: A total of 529 (91%) patients had complete blood counts available in their medical records. Only 35.5% of IBD patients were fully screened for anemia. The prevalence of anemia in IBD patients was 24.6% (29.1% in CD and 19.1% in UC, P=0.008). The anemia was moderate to severe in 16.9% (19.8% in CD and 11.4% in UC, P=0.34). The prevalence of iron deficiency was 52.3% (53.6% in CD and 51.2% in UC, P=0.95). Anemia of chronic disease was present in 14.1% of IBD patients. A total of 53.8% of patients with anemia were in clinical remission. CD was associated with an increased prevalence of anemia (P=0.008; OR=1.76; CI 95% =1.16-2.66) compared to UC. The penetrant disease phenotype in CD was associated with a lower risk of anemia (P<0.0001; OR=0.25; CI 95% =0.14-0.43). Active disease compared to the disease in clinical remission was associated with an increased risk of anemia (P=0.0003; OR=2.61; CI 95% =1.56-4.36) in CD. The presence of anemia was less frequent in patients with CD who underwent surgical bowel resection compared to those who did not undergo surgery (P<0.0001; OR=0.24; CI 95% =0.14-0.40). No differences in anemia prevalence were observed regarding CD localization, age at diagnosis, UC extension or biological therapy (P>0.05). CONCLUSION: Despite the low levels of full screening, anemia and iron deficiency anemia were common manifestations of IBD. CD was associated with an increased risk of anemia, especially with active disease. In addition, patients with CD who underwent surgical bowel resection and penetrant disease phenotype in CD were associated with lower risk of anemia.

Abstract
Iron-deficiency anemia (IDA) was the main condition contributing to higher rates of years lived with disabilities in women in 2016. To date, few studies have investigated gender differences in determinants of IDA in Europe. The aim of the present study was to evaluate the determinants of IDA among females and males in four European countries. IDA determinants were estimated using multivariable Cox regression based on information gathered from national primary care databases, namely Italy (for years 2002-2013), Belgium, Germany, and Spain (for years 2007-2012). Adjusted hazard ratios (aHR) with 95% confidence intervals (CIs) were estimated. Age was significantly associated with IDA in females of childbearing age in all four countries, as well as pregnancy, for which the aHR ranged from 1.20 (95% CI 1.15-1.25) in Italy to 1.88 (95% CI 1.53-2.31) in Germany. In males, the aHR increased with age starting from the 65-69 age group. Menometrorrhagia was associated with IDA in Germany (aHR 2.71, 95% CI 1.96-3.73), Italy (aHR 1.80, 95% CI 1.60-2.03), and Spain (aHR 1.52, 95% CI 1.31-1.76). A greater risk for women with alopecia was also observed. Weakness and headache indicated a higher risk in both men and women. Patients with diseases characterized by blood loss or gastrointestinal malabsorption were also at significantly increased risk. Physicians should encourage women of childbearing age to adhere to dietary recommendations regarding iron intake and regularly prescribe screening of iron status. Upper and lower gastrointestinal investigations should be recommended for patients with a confirmed diagnosis of IDA.

Abstract
Iron plays a key role in many physiological processes; cells need a very exact quantity of iron. In patients with inflammatory bowel disease, anaemia is a unique example of multifactorial origins, frequently being the result of a combination of iron deficiency and anaemia of chronic disease. The main cause of iron deficiency is the activity of the disease. Therefore, the first aim should be to reach complete clinical remission. The iron supplementation route should be determined according to symptoms, severity of anaemia and taking into account comorbidities and individual risks. Oral iron can only be used in patients with mild anaemia, whose disease is inactive and who have not been previously intolerant to oral iron. Intravenous iron should be the first line treatment in patients with moderate-severe anaemia, in patients with active disease, in patients with poor tolerance to oral iron and when erythropoietin agents or a fast response is needed. Erythropoietin is used in a few patients with anaemia to overcome functional iron deficiency, and blood transfusion is being restricted to refractory cases or acute life-threatening situations.

Abstract
AIMS To compare the efficacy and safety of intravenous (IV) ferric carboxymaltose (FCM) versus oral iron and other IV iron therapies in patients with iron-deficiency anemia (IDA) resulting from gastrointestinal (GI) disorders. METHODS A pooled analysis of four prospective, randomized, active-controlled trials in patients with IDA was performed. Efficacy measures included change from baseline in hemoglobin (Hb), ferritin, and transferrin saturation (TSAT) and correlations of baseline Hb, ferritin, and TSAT to change in Hb. The incidence and type of adverse events were evaluated. RESULTS A total of 191 patients were evaluated. The mean change in Hb from baseline to the maximum value was 0.8 g/dL with oral iron (P = 0.001 vs. FCM), 2.2 g/dL with FCM, 2.0 g/dL with any IV iron (P = 0.391 vs. FCM), and 1.9 g/dL with iron sucrose (P = 0.329 vs. FCM). Patients treated with FCM and iron sucrose had larger increases in Hb. This effect may have been attributed to a lower baseline Hb level. Drug-related adverse events occurred in 11.9, 12, 26.2, and 25% and serious adverse events (SAEs) occurred in 6.9, 4, 9.8, and 12.5% of patients in the FCM, oral iron, other IV iron therapies, and iron sucrose groups, respectively. No SAEs were considered treatment related in the FCM group, compared with two treatment-related SAEs in two patients (6.3%) in the iron sucrose group. CONCLUSIONS FCM is an effective therapy in patients with IDA who have GI disorders and has a safety profile comparable to that of other IV iron agents.

Abstract
INTRODUCTION Iron deficiency is a frequent comorbidity of chronic diseases such as inflammatory bowel disease that can severely impact the health and quality of life of affected individuals. It can exist as a silent condition and manifest in non-specific symptoms even in the absence of anemia. Even though iron deficiency anemia is the most common complication and extra-intestinal manifestation of inflammatory bowel disease, the majority of inflammatory bowel disease patients who are diagnosed with iron deficiency anemia are not treated. Areas covered: In this review, we discuss iron deficiency and iron deficiency anemia in patients with inflammatory bowel disease, and review diagnostic and therapeutic options. Expert commentary: We invite international gastroenterological societies and associations to refine the practice guidelines and include iron deficiency as a potential morbidity associated with IBD in analogy to arthritis, uveitis or any other extra intestinal manifestations. There should a more unanimous agreement among different societies on the specific diagnostic cutoff values for C-reactive protein levels, serum ferritin, and transferrin saturation in order to differentiate iron deficiency anemia from anemia of chronic disease.

Adv Pharm Bull 2016; 6:407-413. [PMID: 27766225 DOI: 10.15171/apb.2016.053] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2016] [Revised: 08/29/2016] [Accepted: 08/30/2016] [Indexed: 01/20/2023] Open
Abstract
Purpose: One of the most nutritional disorders around the world is iron deficiency. A novel iron compound was synthesized by chelating ferrous ions with alanine for prevention and treatment of iron deficiency anemia. Methods: The newly synthesized compound was characterized both qualitatively and quantitatively by Fourier Transform Infrared (FT-IR) spectroscopy. The bioavailability of newly synthesized iron micronutrient was evaluated in four groups of Wistar rats. The group I was a negative control group and the other three groups received three different iron formulations. After 14 days, the blood samples were taken and analyzed accordingly. Results: Calculations showed that more than 91.8% of iron was incorporated in the chelate formulation. In vivo studies showed that serum iron, total iron binding capacity and hemoglobin concentrations were significantly increased in group IV, which received ferrous bis alanine chelate compared with the negative control group (p<0.05) and also group II, which received ferrous sulfate.7H2O (p<0.05). It indicates that the new formulation considerably improves the blood iron status compared with the conventional iron compounds. There were no significant differences (p<0.05) in the serum iron between group IV and group III, which received ferrous bis glycine. Conclusion: The results showed better bioavailability of ferrous bis alanine as a new micronutrient for treatment of iron deficiency anemia in comparison with ferrous sulfate. Ferrous bis alanine could be considered as a suitable supplement for prevention and treatment of iron deficiency anemia.

High-dose intravenous treatment in iron deficiency anaemia in inflammatory bowel disease: early efficacy and impact on quality of life. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2016; 14:199-205.

Abstract
BACKGROUND Anaemia and iron deficiency are very common in inflammatory bowel disease. Clinical trials have shown intravenous iron to be effective and well tolerated. However, published experience in clinical practice with specific evaluation of the effect on quality of life is limited. MATERIAL AND METHODS We carried out a prospective, multicentre, observational study on the effects of ferric carboxymaltose in the treatment of iron deficiency anaemia in inflammatory bowel disease. Anaemia and iron deficiency were defined according to World Health Organization criteria. Efficacy and safety were evaluated at infusion, at 2 weeks and at 12 weeks. Quality of life was evaluated according to the SIBDQ-9 index. Complete response was defined as anaemia correction or more tan 2 g/dL increase in haemoglobin. RESULTS A total of 88 courses of ferric carboxymaltose in 72 patients were evaluated. Complete response was observed in 46% of patients at week 2, and 81.2% at week 12. Quality of life improved significatively at week 2 in both complete responders and partial responders (p<0.0005); complete responders showed siginficantly better response (p=0.016). No predictive factor was identified. Only one transient adverse effect was observed; however, this was severe. DISCUSSION Ferric carboxymaltose showed comparable efficacy to that demonstrated in clinical trials. After only two weeks of treatment, there was a significant improvement in quality of life, with a greater effect observed in those patients with a complete haematologic response. Intravenous iron can very quickly improve quality of life in inflammatory bowel disease.

Abstract
Background/Aims Quality of life is closely related to anemia in patients with inflammatory bowel disease (IBD). Several studies have reported on anemia in patients with IBD in Western countries. This study investigated the prevalence and clinical characteristics of anemia in Korean patients with IBD. Methods We reviewed the medical records of 92 patients with ulcerative colitis (UC) and 76 patients with Crohn's disease (CD) who were followed regularly at a single tertiary medical center in Korea between January 2003 and December 2012. Hemoglobin (Hb) thresholds used to define anemia were <13.0 g/dL in men and <12.0 g/dL in women according to the World Health Organization criteria. We chose the lowest Hb level in each year as a representative value because Hb levels changed at each examination and anemia was associated with disease deterioration. The relationship between clinical variables and lowest Hb level was assessed. Results The prevalence of anemia was 36.3% in patients with UC and 41.6% in patients with CD. Anemia in patients with CD was associated with hospital admission, 5-aminosalicylate (5-ASA) and infliximab treatment in men. Anemia in patients with UC was associated with hospital admission, oral steroid use, thiopurine and infliximab treatment in men. Conclusions The prevalence of anemia in Korean patients with IBD was comparable to that of patients in Western countries. Anemia was associated with male patients with CD who were admitted to the hospital and received medications including 5-ASA and infliximab, and men with UC who were admitted to the hospital and received medications including oral steroids, thiopurine and infliximab.

Abstract
Iron deficiency anemia (IDA) continues to be very common worldwide. Intravenous (IV) iron is an infrequently used therapeutic option in children with IDA despite numerous studies in adults and several small but notable pediatric studies showing efficacy and safety. Presently, the availability of newer IV iron products allows for replacement of the total iron deficit at a single setting. These products appear safer compared to the high molecular weight iron dextrans of the past. Herein, we review the medical literature and suggest that front line use of IV iron should be strongly considered in diseases associated with IDA in children.

Abstract
Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD.

Abstract
OPINION STATEMENT Anaemia is a common multifactorial extraintestinal manifestation in IBD patients. Moreover, anaemia represents an important health problem among the elderly population and has a significant impact on healthcare utilisation and costs. Data on the prevalence, diagnosis and management of anaemia in elderly IBD patients are scarce, since clinical trials have largely excluded this population. In this review, we reconsider anaemia in older IBD patients in the light of new diagnostic and therapeutic tools.

Abstract
Objective. To provide clinicians with evidence-based guidance for iron therapy dosing in patients with iron deficiency anemia (IDA), we conducted a study examining the benefits of a higher cumulative dose of intravenous (IV) iron than what is typically administered. Methods. We first individually analyzed 5 clinical studies, averaging the total iron deficit across all patients utilizing a modified Ganzoni formula; we then similarly analyzed 2 larger clinical studies. For the second of the larger studies (Study 7), we also compared the efficacy and retreatment requirements of a cumulative dose of 1500 mg ferric carboxymaltose (FCM) to 1000 mg iron sucrose (IS). Results. The average iron deficit was calculated to be 1531 mg for patients in Studies 1-5 and 1392 mg for patients in Studies 6-7. The percentage of patients who were retreated with IV iron between Days 56 and 90 was significantly (p < 0.001) lower (5.6%) in the 1500 mg group, compared to the 1000 mg group (11.1%). Conclusions. Our data suggests that a total cumulative dose of 1000 mg of IV iron may be insufficient for iron repletion in a majority of patients with IDA and a dose of 1500 mg is closer to the actual iron deficit in these patients.

Abstract
Iron deficiency is common in patients with inflammatory bowel disease (IBD), but can be difficult to diagnose in the presence of inflammation because ferritin is an acute phase reactant. The transferrin receptor-ferritin index (TfR-F) has a high sensitivity and specificity for iron deficiency diagnosis in chronic diseases. The diagnostic efficacy of TfR-F is little known in patients with IBD. The aim of the study was to assess the added value of TfR-F to iron deficiency diagnosis in a prospective cohort of patients with IBD.Consecutive IBD patients were prospectively enrolled. Patients were excluded in case of blood transfusion, iron supplementation, or lack of consent. IBD activity was assessed on markers of inflammation (C-reactive protein, endoscopy, fecal calprotectin). Hemoglobin, ferritin, vitamin B9 and B12, Lactate dehydrogenase, haptoglobin, and soluble transferrin receptor (sTfR) were assayed. TfR-F was calculated as the ratio sTfR/log ferritin. Iron deficiency was defined by ferritin <30 ng/mL or TfR-F >2 in the presence of inflammation.One-hundred fifty patients with median age 38 years (16-78) and Crohn disease (n = 105), ulcerative colitis (n = 43), or unclassified colitis (n = 2) were included. Active disease was identified in 45.3%. Anemia was diagnosed in 28%. Thirty-six patients (24%) had ferritin <30 ng/mL. Thirty-two patients (21.3%) had ferritin levels from 30 to 100 ng/ml and inflammation: 2 had vitamin B12 deficiency excluding TfR-F analysis, 13 of 30 (43.3%) had TfR-F >2. Overall, iron deficiency was diagnosed in 32.7% of the patients.TfR-F in addition to ferritin <30 ng/mL criterion increased by 36% diagnosis rates of iron deficiency. TfR-F appeared as a useful biomarker that could help physicians to diagnose true iron deficiency in patients with active IBD.

Abstract
Background and aims Iron deficiency is common in inflammatory bowel disease, yet oral iron therapy may worsen the disease symptoms and increase systemic and local oxidative stress. The aim of this study was to compare the effects of oral ferrous sulfate and iron polymaltose complex on inflammatory and oxidative stress markers in colitic rats. Methods Animals were divided into four groups with ten animals each. Rats of three groups received dextran sodium sulfate to induce colitis and animals of two of these groups received 5 mg iron/kg of body weight a day, as ferrous sulfate or iron polymaltose complex, for 7 days. Gross colon anatomy, histology of colon and liver, stainings of L-ferritin, Prussian blue, hepcidin, tumor necrosis factor-α, and interleukin-6, as well serum levels of liver enzymes, inflammatory markers, and iron markers, were assessed. Results Body weight, gross anatomy, crypt injury and inflammation scores, inflammatory parameters in liver and colon, as well as serum and liver hepcidin levels were not significantly different between colitic animals without iron treatment and colitic animals treated with iron polymaltose complex. In contrast, ferrous sulfate treatment caused significant worsening of these parameters. As opposed to ferrous sulfate, iron polymaltose complex caused less or no additional oxidative stress in the colon and liver compared to colitic animals without iron treatment. Conclusion Iron polymaltose complex had negligible effects on colonic tissue erosion, local or systemic oxidative stress, and local or systemic inflammation, even at high therapeutic doses, and may thus represent a valuable oral treatment of iron deficiency in inflammatory bowel disease.

Abstract
OBJECTIVE Anaemia is frequently seen in inflammatory bowel disease (IBD) and needs appropriate treatment. This online questionnaire investigated the patients' perceptions of anaemia: symptoms, prevalence, treatment and impact on quality of life. METHODS Patients participated in this survey in 2012. Respondents were mainly from Europe, but also from North America and Asia Pacific. RESULTS A total of 631 patients completed the questionnaire; most had Crohn's disease, and 41.2% were in remission, 29.8% had mildly active flares, 16.8% had moderately active flares, and 5.4% had severely active flares. When asked about anaemia, 67% believed that anaemia occurred frequently in IBD and was associated with blood loss (45%), iron deficiency (31%), or inflammation (18%). Symptoms commonly reported by patients with anaemia were fatigue and weakness. Fatigue associated with anaemia occurred daily in 53% of patients and negatively impacted the quality of life.A number of patients had not discussed anaemia with a healthcare professional, and 33% of patients with anaemia had not received treatment. Of those treated, 42% took oral prescription iron, 27% intravenous iron, 19% nonprescription iron supplements and 10% prescription liquid or syrup iron. The majority of patients taking liquid or syrup iron (77%), oral iron (74%) and iron supplements (68%) were dissatisfied with their treatment, primarily because of poor tolerability. In contrast, 72% were satisfied with intravenous iron treatment. CONCLUSION IBD patients are mostly aware of the main signs and symptoms of anaemia. Oral iron is most commonly prescribed, but may cause dissatisfaction because of tolerability issues. Most patients prescribed intravenous iron are satisfied with treatment.

Abstract
Nutritional anemia is the most common type of anemia, affecting millions of people in all age groups worldwide. While inadequate access to food and nutrients can lead to anemia, patients with certain health status or medical conditions are also at increased risk of developing nutritional anemia. Iron, cobalamin, and folate are the most recognized micronutrients that are vital for the generation of erythrocytes. Iron deficiency is associated with insufficient production of hemoglobin. Deficiency of cobalamin or folate leads to impaired synthesis of deoxyribonucleic acid, proteins, and cell division. Recent research has demonstrated that the status of copper and zinc in the body can significantly affect iron absorption and utilization. With an increasing number of patients undergoing bariatric surgical procedures, more cases of anemia associated with copper and zinc deficiencies have also emerged. The intestinal absorption of these 5 critical micronutrients are highly regulated and mediated by specific apical transport mechanisms in the enterocytes. Health conditions that persistently alter the histology of the upper intestinal architecture, expression, or function of these substrate-specific transporters, or the normal digestion and flow of these key micronutrients, can lead to nutritional anemia. The focus of this article is to review the science of intestinal micronutrient absorption, discuss the clinical assessment of micronutrient deficiencies in relation to anemia, and suggest an effective treatment plan and monitoring strategies using an evidence-based approach.

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.
