Abstract
The inflammatory bowel diseases (IBDs) are systemic conditions that affect not only the gastrointestinal tract but also other parts of the body. The presence of extraintestinal manifestations can significantly impact the quality of life in IBD patients. Peripheral arthritis, episcleritis, and erythema nodosum are frequently associated with active intestinal inflammation and often improve with standard treatment targeting intestinal inflammation. In contrast, anterior uveitis, ankylosing spondylitis, and primary sclerosing cholangitis typically occur independently of disease flares. The incidence of these conditions in individuals with IBD can reach up to 50% of patients over the course of their lifetime. In addition, some advanced therapies utilized for the treatment of IBD potentially result in side effects that may resemble extraintestinal manifestations. This review provides a thorough analysis of the pathophysiology and treatment of extraintestinal manifestations associated with Crohn's disease and ulcerative colitis.

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
Iron deficiency (ID) is a common and challenging problem in adolescence. In order to prevent, recognize, and treat ID in this age range, it is critical to understand the recommended daily intake of iron in relation to an adolescent's activity, dietary habits, and basal iron losses. Adolescents following vegetarian or vegan diets exclusively rely on plant-based, nonheme iron, which has decreased bioavailability compared with heme iron and requires increased total iron intake. Individuals with disordered eating habits, excessive menstrual blood loss, and certain chronic health conditions (including inflammatory bowel disease and heart failure) are at high risk of ID and the development of symptomatic iron deficiency anemia (IDA). Adolescent athletes and those with sleep and movement disorders may also be more sensitive to changes in iron status. Iron deficiency is typically treated with oral iron supplementation. To maximize iron absorption, oral iron should be administered no more than once daily, ideally in the morning, while avoiding foods and drinks that inhibit iron absorption. Oral iron therapy should be provided for ≥3 mo in the setting of ID to reach a ferritin of 20 ng/mL before discontinuation. Intravenous iron is being increasingly used in this population and has demonstrated efficacy and safety in adolescents. It should be considered in those with persistent ID despite a course of oral iron, severe and/or symptomatic IDA, and chronic inflammatory conditions characterized by decreased gastrointestinal iron absorption.

Abstract
OBJECTIVES Anemia is one of the most common extraintestinal manifestations of pediatric inflammatory bowel disease (IBD). We aimed to evaluate the prevalence of anemia in children newly diagnosed with IBD and assess the efficacy and safety of oral iron therapy over a 12-month follow-up period. METHODS This single-center, retrospective, observational cohort study included all children newly diagnosed with IBD at the Pediatric Gastroenterology Unit of Sapienza University of Rome from May 2015 to May 2019 presenting with anemia. At baseline, demographic, clinical, laboratory data (hemoglobin, mean corpuscular volume, serum iron, ferritin, transferrin levels, erythrocyte sedimentation rate, and C-reactive protein), and treatment received, were recorded. Clinical and laboratory data, as well as anemia therapy and adverse events (AEs), were collected every 3 months during the 1-year follow-up. RESULTS Eighty-nine out of 140 patients newly diagnosed with IBD presented with anemia (64%); 13 were excluded due to incomplete follow-up, thus 76 were included [median age 12.7 (interquartile range 9.8-15), 25 (33%) Crohn disease, 51 (67%) ulcerative colitis]. All patients received sucrosomial iron (SI) alone or in combination with intravenous ferric carboxymaltose. Treatment with SI was effective in 67 (88%) patients at the end of follow-up [37 (48%) within 3 months], regardless of anemia severity at baseline. No serious AEs related to SI treatment were reported. CONCLUSIONS We confirmed a high prevalence of anemia at the time of the diagnosis of pediatric IBD. Our data suggest that SI is safe and effective, leading to anemia resolution in approximately half of the patients within 3 months.

Abstract
BACKGROUND/AIMS Clinical characteristics of inflammatory bowel disease (IBD) with anemia have not been fully elucidated. This study aimed to investigate the frequency of, risk factors for, and management of anemia in IBD patients and to evaluate the quality of life (QOL) in IBD patients with anemia. METHODS We included two patient cohorts. In cohort 1, clinical data from 697 IBD patients were retrospectively collected. In cohort 2, the Short Form-36 Health Survey (SF-36) and Fatigue Scale-14 (FS-14) questionnaires for IBD patients were completed to evaluate the QOL. RESULTS Anemia was present in 35.6% of IBD patients [38.2% of Crohn's disease (CD) patients vs. 29.3% of ulcerative colitis (UC) patients, P = 0.025]. Elevated platelet (PLT) count (CD: OR, 1.004; 95% CI, 1.001-1.007; P = 0.007; UC: OR, 1.010; 95% CI, 1.004-1.016; P = 0.001), elevated erythrocyte sedimentation rate (ESR) (CD: OR, 1.024; 95% CI, 1.012-1.036; P < 0.001; UC: OR, 1.025; 95% CI, 1.001-1.051; P = 0.044), and lower albumin levels (CD: OR, 0.801; 95% CI, 0.749-0.857; P < 0.001; UC: OR, 0.789; 95% CI, 0.720-0.864; P < 0.001) were associated with anemia. Among the IBD patients with anemia, only 25.8% received treatment for anemia. IBD patients with anemia had significantly lower SF-36 scores (P = 0.011) and higher FS-14 scores (P = 0.026) than those without anemia. CONCLUSION Anemia is common in IBD patients. Elevated PLT count and ESR are risk factors for anemia in IBD patients. Anemia may negatively impact IBD patients' QOL, but few anemia patients receive treatment for anemia.

Abstract
Anemia is a major health issue and associated with increased morbidity. Iron deficiency anemia (IDA) is the most prevalent, followed by anemia of chronic disease (ACD). IDA and ACD often co-exist, challenging diagnosis and treatment. While iron supplementation is the first-line therapy for IDA, its optimal route of administration and the efficacy of different repletion strategies in ACD are elusive. Female Lewis rats were injected with group A streptococcal peptidoglycan-polysaccharide (PG-APS) to induce inflammatory arthritis with associated ACD and/or repeatedly phlebotomized and fed with a low iron diet to induce IDA, or a combination thereof (ACD/IDA). Iron was either supplemented by daily oral gavage of ferric maltol or by weekly intravenous (i.v.) injection of ferric carboxymaltose for up to 4 weeks. While both strategies reversed IDA, they remained ineffective to improve hemoglobin (Hb) levels in ACD, although oral iron showed slight amelioration of various erythropoiesis-associated parameters. In contrast, both iron treatments significantly increased Hb in ACD/IDA. In ACD and ACD/IDA animals, i.v. iron administration resulted in iron trapping in liver and splenic macrophages, induction of ferritin expression and increased circulating levels of the iron hormone hepcidin and the inflammatory cytokine interleukin-6, while oral iron supplementation reduced interleukin-6 levels. Thus, oral and i.v. iron resulted in divergent effects on systemic and tissue iron homeostasis and inflammation. Our results indicate that both iron supplements improve Hb in ACD/IDA, but are ineffective in ACD with pronounced inflammation, and that under the latter condition, i.v. iron is trapped in macrophages and may enhance inflammation.

Abstract
Crohn's disease is a chronic inflammatory condition that can involve any area in the gastrointestinal tract often involving the distal ileum where vitamin B12 is specifically absorbed. The aim of this study was to ascertain serum vitamin B12 and folate levels in order to investigate the correlation among these vitamin levels and disease activation, localization, duration and age at the onset of the disease. Study population included 103 patients with Crohn's disease and a healthy control group of 114 individuals. C-reactive protein, vitamin B12, folate levels were studied along with hemogram analyses. The results were evaluated in statistical comparisons. While serum vitamin B12 levels and serum folate levels were 161.9 ± 63.2(73-496) pg/mL and 4.9 ± 1.4(1.2-9.4) ng/mL in the Crohn's patient group respectively, they were 321.7 ± 126.3(85-680) pg/mL and 7.6 ± 3.8(3-25.1) ng/mL in the control group respectively. Vitamin B12 and folate levels were distinctly lower in patients with Chron's disease than those of the control group (P < .001). The intragroup analysis of the patient group revealed that low vitamin B12 levels were significantly lower in the moderate group classified according to the Crohn's Disease Activity Index (P < .001), along with those in the L1 group with terminal/distal ileal involvement (P < .001). Vitamin B12 and folate deficiencies are quite prevalent in patients with Crohn's disease while this condition can lead to various complications and they prove to be important risk factors associated especially with thrombosis and its complications. Patients must be regularly followed-up for vitamin B12 and folate levels to supplement them where needed.

Abstract
One of the most common extraintestinal manifestations of inflammatory bowel disease is iron deficiency anemia. It is often an untreated condition that significantly impairs patients' quality of life and elevates mortality and morbidity. Although it is often accompanied by mild symptoms (e.g., fatigue, lethargy), it can provoke severe health conditions, such as dyspnea, palpitation, angina, and mental disorders, and increases hospitalization and mortality rate as well. As anemia develops through several pathomechanisms, such as occult bleeding, chronic inflammation, and medicines (e.g., methotrexate), treating anemia effectively requires to manage the underlying pathological changes as well. Based on international publications and data, it is a frequent condition and more frequent in pediatrics. According to Goodhand et al., iron deficiency is present in more than 60% of children, whereas only 14% of them received oral iron therapy. Compared to adult patients, 22% have iron deficiency, and 48% of them received oral and 41% intravenous iron therapy. Miller et al. also highlighted that among young patients iron deficiency anemia is a frequent condition, as almost 50% of the patients were anemic in their cohort. European Crohn's and Colitis Organisation's statements are clear regarding the diagnosis of iron deficiency anemia, and the iron supplementation as well. Third-generation parenteral iron supplementations seem to be safer and more effective than oral iron pills. Oral iron in many cases cannot replace the iron homeostasis as well; furthermore, it can provoke dysbiosis, which can potentially lead to relapse. As a result, we claim that both oral and parenteral should be used more frequently; furthermore, intravenous iron could replace oral medicines as well in certain cases. Despite the fact that iron deficiency anemia is examined by many aspects, further questions can be raised. Can it imply underlying pathological lesions? Are both oral and intravenous iron therapy safe and effective? When and how are they used? We demand that more studies should be conducted regarding these issues.

Abstract
Introduction: Iron Deficiency Anemia (IDA) is a leading cause of anemia in Inflammatory Bowel disease (IBD). IDA affects quality of life (QoL) and lead to developmental and cognitive abnormalities. Diagnosis of IDA in IBD is complicated as biochemical tests available at present cannot help distinguish between IDA and anemia of chronic disease. Soluble transferrin receptor ferritin index has been gaining popularity as it can diagnose IDA in presence of chronic inflammation. ECCO guidelines recommend a Hb increase of >2 g/dL and a TfS of >30% within 4 weeks as adequate therapeutic response. IV iron is preferred over oral iron as it bypasses gastrointestinal tract, rapidly increases haemoglobin, and is not associated with intestinal inflammation. Our aim in this review is to provide apathway for physicians to help them diagnose and appropriately treat IDA in IBD.Areas covered: In this review article, we have discussed current diagnosis and treatment in detail and have proposed new directions on how future research can help manage IDA in IBD effectively.Expert opinion: Understanding the pathogenesis of IDA in IBD will further lead to exploring new potential diagnostic tests and treatment regimens for effective management of IDA in IBD.

Abstract
Mucosal damage, barrier breach, inflammation, and iron-deficiency anemia (IDA) typify ulcerative colitis (UC) in humans. The anemia in UC appears to mainly relate to systemic inflammation. The pathogenesis of this ‘anemia of inflammation’ (AI) involves cytokine-mediated transactivation of hepatic Hamp (encoding the iron-regulatory hormone, hepcidin). In AI, high hepcidin represses iron absorption (and iron release from stores), thus lowering serum iron, and restricting iron for erythropoiesis (causing anemia). In less-severe disease states, inflammation may be limited to the intestine, but whether this perturbs iron homeostasis is uncertain. We hypothesized that localized gut inflammation will increase overall iron demand (to support the immune response and tissue repair), and that hepatic Hamp expression will decrease in response, thus derepressing (i.e., enhancing) iron absorption. Accordingly, we developed a rat model of mild, acute colitis, and studied iron absorption and homeostasis. Rats exposed (orally) to DSS (4%) for 7 days had intestinal (but not systemic) inflammation, and biomarker analyses demonstrated that iron utilization was elevated. Iron absorption was enhanced (by 2-3-fold) in DSS-treated, WT rats of both sexes, but unexpectedly, hepatic Hamp expression was not suppressed. Therefore, to gain a better understanding of regulation of iron absorption during acute colitis, Hamp KO rats were used for further experimentation. The severity of DSS-colitis was similar in Hamp KOs as in WT controls. In the KOs, increased iron requirements associated with the physiological response to colitis were satisfied by mobilizing hepatic storage iron, rather than by increasing absorption of enteral iron (as occurred in WT rats). In conclusion then, in both sexes and genotypes of rats, iron absorption was appropriately modulated to match physiological demand for dietary iron during acute intestinal inflammation, but regulatory mechanisms may not involve hepcidin.

Abstract
Celiac disease (CD) is an autoimmune disorder characterized by intolerance to dietary gluten in genetically predisposed subjects. Iron deficiency anemia (IDA) is a common sign in CD, being the only abnormality in approximately 40% of celiac patients. A multifactorial etiology leads to IDA in CD. The two main causes are the villous atrophy of the mucosa at the site of iron absorption (the duodenum) and the resulting inflammation, which triggers the mechanism that leads to the anemia of chronic disease. Until now, it has been unclear why some patients with CD continue to have IDA despite a careful gluten-free diet (GFD) and the normalization of villous atrophy. Furthermore, some celiac patients are refractory to oral iron supplementation despite the healing of the mucosa, and they thus require periodic intravenous iron administration. The Marsh classification evaluates the degree of inflammation and villous atrophy, but it does not assess the possible persistence of ultrastructural and molecular alterations in enterocytes. The latter was found in CD in remission after adopting a GFD and could be responsible for the persistently reduced absorption of iron and IDA. Even in non-celiac gluten sensitivity, anemia is present in 18.5-22% of patients and appears to be related to ultrastructural and molecular alterations in intestinal microvilli. It is possible that a genetic component may also play a role in IDA. In this review, we evaluate and discuss the main mechanisms of IDA in CD and the possible causes of its persistence after adopting a GFD, as well as their therapeutic implications.

Abstract
Red blood cell distribution width is a parameter measured automatically in every complete blood count that actually reflects the degree of anisocytosis of the red blood cell population. It is a cost-effective tool used in everyday clinical practice along with other parameters to define and narrow the cause of anemia. In a series of pathologic entities, such as cardiovascular diseases, autoimmune diseases, malignancy, chronic renal diseases and chronic respiratory diseases, where inflammation and oxidative stress comprise the major pathophysiologic insults, red cell distribution width behaves as a significant and competent marker able to predict and assess disease activity and severity. A number of clinical studies based on these observations have aimed to evaluate its potential utility as an index of activity in inflammatory bowel disease. In this narrative review we present data from the international literature regarding its ability to express disease activity and we look into its relation with clinical, laboratory and endoscopic indices used to identify active disease. According to the results of published clinical trials, red cell distribution width is considerably correlated with disease activity and might serve as an index to differentiate Crohn's disease from ulcerative colitis.

Abstract
OBJECTIVES Iron deficiency anemia (IDA) is very common in children with inflammatory bowel disease (IBD). While health-related quality of life (HRQL) is a key outcome measure, no long-term studies have evaluated the effect of correction of IDA on HRQL in children with IBD. Our goal was to prospectively study changes in HRQL in iron-deficient children with IBD receiving routine iron supplementation with periodic intravenous iron sucrose (IVIS). METHODS Thirty-eight children with IBD treated with infliximab participated. Hematology and inflammatory markers were assessed before each infliximab treatment. Iron-deficient patients (transferrin saturation below 20% and/or ferritin below 30 ng/mL or 100 ng/mL with normal or elevated C-reactive protein, respectively) received IVIS after each infliximab infusion until iron indices stayed normal for two consecutive measurements. HRQL was assessed with Pediatric Quality of Life Inventory every 4 months. Correlation between changes in mean hemoglobin levels and HRQL scores was analyzed prospectively in 3-month periods over a period exceeding 3 years. RESULTS At enrollment, 27 patients had already been established on infliximab; 11 had not started or completed induction. Mean iron indices and hemoglobin normalized after 3 and 6 month of starting IVIS, respectively. Multiple HRQL parameters significantly improved, regardless of the duration of infliximab treatment at the time of enrollment. There was a statistically significant positive correlation between correction of anemia and improvement in parent-reported emotional and physical HRQL scores. CONCLUSIONS Periodic IVIS resulted in long-term correction of IDA in children with IBD. Correction of IDA contributed to some improvements in HRQL.

Abstract
Inflammatory bowel disease (IBD) is a worldwide healthcare problem calling for the development of new therapeutic drugs. Angelica sinensis and Zingiber officinale Roscoe are two common dietetic Chinese herbs, which are traditionally used for complementary treatment of gastrointestinal disorders. As bioactive constituents, volatile and pungent substances of these two herbs could be effectively extracted together by supercritical fluid extraction. In this study, the supercritical fluid extract of Angelica sinensis and Zingiber officinale Roscoe (AZ-SFE) was obtained by an optimized extraction process and it was chemically characterized. The anti-inflammatory effect and underlying mechanism of AZ-SFE were evaluated in a lipopolysaccharide (LPS)-induced RAW264.7 cell model and a 2, 4, 6-trinitrobenzenesulfonic acid (TNBS)-induced colitis rat model. AZ-SFE notably inhibited the production of NO in LPS-stimulated macrophages, and it inhibited the proliferation of Concanavalin A (Con A)-induced splenocytes with suppression of the Th1 immune response. In vivo, the study demonstrated that AZ-SFE significantly alleviated disease activity, colonic shortening, macroscopic damage and histological injury of TNBS-treated rats with reduction of oxidative stress, suppression of inflammatory cytokines, and modulation of hepcidin and serum iron. These findings suggested that AZ-SFE may be a promising supplement for current IBD therapy.

Abstract
Fatigue is an important clinical problem in patients with IBD, affecting nearly 50% of patients in clinical remission and > 80% of those with active disease. The resulting decrease in quality of life and impaired work productivity and functioning contribute markedly to the societal costs of fatigue. However, despite the burden and effects of fatigue, little is known about its aetiology and pathophysiology, which impairs our ability to effectively treat this symptom. Here, we review the theories behind the development of fatigue in IBD and the role of contributing factors, including nutritional deficiency, inflammation and altered metabolism. We also explore the potential role of the gut microbiome in mediating fatigue and other psychological symptoms through the gut-brain axis. We discuss the efficacy of nutrient repletion and various psychological and pharmacological interventions on relieving fatigue in patients with IBD and expand the discussion to non-IBD-related fatigue when evidence exists. Finally, we present a therapeutic strategy for the management of fatigue in IBD and call for further mechanistic and clinical research into this poorly studied symptom.

Abstract
BACKGROUND While very low birth weight (VLBW) infants often require multiple red blood cell transfusions, efforts to minimize transfusion-associated risks have resulted in more restrictive neonatal transfusion practices. However, whether restrictive transfusion strategies limit transfusions without increasing morbidity and mortality in this population remains unclear. Recent epidemiologic studies suggest that severe anemia may be an important risk factor for the development of necrotizing enterocolitis (NEC). However, the mechanism whereby anemia may lead to NEC remains unknown. STUDY DESIGN AND METHODS The potential impact of anemia on neonatal inflammation and intestinal barrier disruption, two well-characterized predisposing features of NEC, was defined by correlation of hemoglobin values to cytokine levels in premature infants and by direct evaluation of intestinal hypoxia, inflammation and gut barrier disruption using a pre-clinical neonatal murine model of phlebotomy-induced anemia (PIA). RESULTS Increasing severity of anemia in the preterm infant correlated with the level of IFN-gamma, a key pro-inflammatory cytokine that may predispose an infant to NEC. Gradual induction of PIA in a pre-clinical model resulted in significant hypoxia throughout the intestinal mucosa, including areas where intestinal macrophages reside. PIA-induced hypoxia significantly increased macrophage pro-inflammatory cytokine levels, while reducing tight junction protein ZO-1 expression and increasing intestinal barrier permeability. Macrophage depletion reversed the impact of anemia on intestinal ZO-1 expression and barrier function. CONCLUSIONS Taken together, these results suggest that anemia can increase intestinal inflammation and barrier disruption likely through altered macrophage function, leading to the type of predisposing intestinal injury that may increase the risk for NEC.

Abstract
Introduction Anaemia is the most common extraintestinal manifestation of inflammatory bowel disease, which has a negative impact on quality of life. Aim To determinate the prevalence, risk factors, and aetiology of anaemia in newly diagnosed patients with inflammatory bowel disease (IBD).Material and methods: We included 136 newly diagnosed patients with IBD. We analysed patient age, sex, laboratory tests, endoscopic and radiological examination, length of stay, and the course of hospitalisation. Results Anaemia at the time of IBD diagnosis was detected in 89 (65.4%) patients: 51 (57.3%) patients with ulcerative colitis vs. 38 (42.7%) patients with Crohn's disease; p = 0.052. Female patients were more frequently anaemic than male patients (59.6% vs. 40.4%; p = 0.001). Anaemia was more often diagnosed in Crohn's disease patients with ileocolonic involvement compared to other types of disease location (70.96% vs. 56.52%, respectively; p = 0.03). The prevalence of anaemia at the time of diagnosis for ulcerative colitis patients increased with disease extension: for extensive colitis anaemia was diagnosed in 64.71% compared to 35.29% in limited extension (p < 0.05). Anaemic patients were hospitalised for significantly longer than patients with no anaemia (7.95 ±3.8 days vs. 5.88 ±2.7 days for Crohn's disease; p = 0.02 and 9.02 ±5.0 days vs. 5.00 ±2.4 days for ulcerative colitis; p < 0.05). Conclusions Anaemia represents a frequent complication of IBD not only during the long-term course of the disease, but also at the moment of diagnosis. Anaemia is one of the factors extending the time of hospitalisation. Female sex and disease extent are strong determinant factors connected with anaemia.

Abstract
BACKGROUND In conditions associated with inflammation, biochemical parameters alone could be inadequate for assessing iron status. We investigated the potential utility of mean reticulocyte hemoglobin content (MCHr) in the assessment of the erythropoiesis status in inflammatory bowel disease (IBD). METHODS We recruited 124 anemic outpatients with IBD. Serum iron, transferrin and ferritin were tested. Complete blood counts were performed on a CELL-DYN Sapphire analyzer (Abbott Diagnostics). Differences among groups were assessed using analysis of variance, considering P < 0.05 to be significant. Receiver operating characteristic analysis was used to assess the diagnostic performance of MCHr for detecting iron deficient erythropoiesis. The reference used as an indicator of insufficient iron availability was transferrin saturation <20%. RESULTS Overall, 47.6% of the patients had iron deficiency anemia (IDA) and 31.5% anemia of chronic disease (ACD), while the others (20.9%) had mixed anemia. Patients with ACD or mixed anemia showed functional iron deficiency: normal or high ferritin and low MCHr. The area under curve was 0.858 (95% CI 0.742-0.942), considering a cut off 30.3 pg, the sensitivity was 82.2%, specificity 83.3%. CONCLUSIONS MCHr provides information on iron availability in IBD patients. It is a reliable test to assess iron supply for erythropoiesis.

Abstract
OBJECTIVES Anemia is the most frequent extra-intestinal finding in inflammatory bowel disease (IBD). The aim of this study is to determine the prevalence and types of anemia in pediatric patients with IBD at diagnosis and at approximately 1 year follow-up. METHODS This is a retrospective chart review of patients diagnosed with IBD from 2005 to 2012, ages 1 to 18 years. Patients who had hemoglobin, hematocrit, mean corpuscular volume, and iron indices obtained at the time of diagnosis and at approximately 1 year follow-up were included in the study. The prevalence of anemia at the beginning and the end of the study was recorded. Using the soluble transferrin receptor index the type of anemia was determined. RESULTS At diagnosis, 67.31% of patients were anemic. Overall, 28.85% of patients had either iron deficiency anemia (IDA) or a combination of IDA and anemia of chronic disease (ACD), whereas 38.46% had ACD alone. At follow-up, 20.51% were anemic. 15.38% had either IDA or a combination of IDA and ACD; 5.13% had ACD alone. The pattern of anemia and response to therapy differed among the IBD phenotypes CONCLUSIONS:: Anemia is frequent in inflammatory bowel disease. The prevalence was higher in Crohn disease (CD). At 1 year, the prevalence of anemia decreased significantly, but persisted. Anemia of chronic disease predominated in CD. Iron deficiency anemia continued to be present in CD and ulcerative colitis.

Abstract
BACKGROUND The incidence and short-term outcome of anaemia in inflammatory bowel disease (IBD) are largely unknown. AIM To determine the incidence, prevalence and clinical outcome of anaemia in terms of resolution of anaemia within 12 months. We also planned to assess risk factors for anaemia in IBD. METHODS A random sample of 342 patients was obtained from the population-based IBD cohort of Örebro University Hospital, Sweden, consisting of 1405 patients diagnosed between 1963 and 2010. Haemoglobin measurements recorded from 1 January 2011 to 31 December 2013 were extracted from the Clinical Chemistry data system. RESULTS In Crohn's disease, the incidence rate of anaemia was 19.3 (95% CI: 15.4-23.7) per 100 person-years and the prevalence was 28.7% (CI: 22.0-36.2), compared with 12.9 (CI: 9.8-16.5) and 16.5% (CI: 11.2-22.9) for ulcerative colitis. Crohn's disease was associated with an increased incidence (OR = 1.60; CI: 1.02-2.51) and prevalence of anaemia (OR = 2.04; CI: 1.20-3.46) compared to ulcerative colitis. Stricturing disease phenotype in Crohn's disease (HR = 2.59; CI: 1.00-6.79) and extensive disease in ulcerative colitis (HR = 2.40; CI: 1.10-5.36) were associated with an increased risk of anaemia. Despite a higher probability of receiving specific therapy within 3 months from the diagnosis of anaemia, Crohn's disease patients had a worse outcome in terms of resolution of anaemia within 12 months (56% vs 75%; P = 0.03). CONCLUSIONS Anaemia is a common manifestation of IBD even beyond the first years after the diagnosis of IBD. Crohn's disease is associated with both an increased risk and a worse outcome.

Abstract
BACKGROUND The objective of this study was to identify an association among dietary components, iron, and inflammatory status among adolescent girls. METHOD Dietary information for 85 adolescent girls was collected through food frequency questionnaires. Biomarkers of iron and inflammatory status were analyzed. RESULTS We found that 28.2% of adolescent girls had anemia and 65.9% girls were iron-deficient. Girls who did not consume guava had 3.8-fold (95% confidence interval =1.1-9.4; p = 0.020) increased the risk of having low serum iron levels. Girls who consumed amaranth had significantly (p = 0.024) higher serum hepcidin levels (n = 44; 129.7 ± 81.40 pg/mL vs n = 41; 94.6 ± 55.8 pg/mL) as well as ferritin levels (n = 44; 19.7 ± 16.4 µg/L vs n = 41; 14.0 ± 10.2 µg/L). Overall consumption of fruits and green leafy vegetables among girls significantly affects their iron status. CONCLUSIONS Regular consumption of vitamin C-rich fruits and green leafy vegetable intake are imperative for improvement of iron status among adolescent girls.

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
Anaemia is the most frequent, though often neglected, comorbidity of inflammatory bowel disease (IBD). Here we want to briefly present (1) the burden of anaemia in IBD, (2) its pathophysiology, which mostly arises from bleeding-associated iron deficiency, followed by (3) diagnostic evaluation of anaemia, (4) a balanced overview of the different modes of iron replacement therapy, (5) evidence for their therapeutic efficacy and subsequently, (6) an updated recommendation for the practical management of anaemia in IBD. Following the introduction of various intravenous iron preparations over the last decade, questions persist about when to use these preparations as opposed to traditional and other novel oral iron therapeutic agents. At present, oral iron therapy is generally preferred for patients with quiescent IBD and mild iron-deficiency anaemia. However, in patients with flaring IBD that hampers intestinal iron absorption and in those with inadequate responses to or side effects with oral preparations, intravenous iron supplementation is the therapy of choice, although information on the efficacy of intravenous iron in patients with active IBD and anaemia is scare. Importantly, anaemia in IBD is often multifactorial and a careful diagnostic workup is mandatory for optimized treatment. Nevertheless, limited information is available on optimal therapeutic start and end points for treatment of anaemia. Of note, neither oral nor intravenous therapies seem to exacerbate the clinical course of IBD. However, additional prospective studies are still warranted to determine the optimal therapy in complex conditions such as IBD.

Abstract
We investigated the association between iron status, B12, and inflammatory markers among 101 adolescent girls. We found that B12 showed significant negative association with tumor necrosis factor-alpha (TNF-α) (rs = -0.232, P = 0.020) and positive association with serum ferritin (SF) (rs = 0.209, P = 0.036) among girls. Our results showed that hepcidin discriminates anemic and non-anemic population under normal B12 conditions. The logistic regression analysis revealed that the risk of having higher TNF-α levels was 13.2 times higher in low B12 girls in the presence of anemia compared to the girls having normal hemoglobin and B12 levels.

Abstract
BACKGROUND AND AIM Inflammatory bowel diseases (IBD), including Crohn disease (CD) and ulcerative colitis (UC), are chronic pediatric disorders. Changes in vasculature are described in IBD, but these could be secondary to inflammation and the role in pathogenesis is poorly understood. Assessing circulatory changes in typically unaffected sites in IBD (eg, duodenum), when inflammation is absent, can identify vascular changes associated with pathogenesis. The aim of the study is to measure capillary flow rates in duodenal mucosa using probe-based confocal laser endomicroscopy (pCLE) during endoscopy in children with IBD. METHODS Images of villi with visible blood vessels obtained using pCLE were captured as video sequences. Capillary flow rate (mm/s) was calculated by dividing the distance travelled by blood cells by the duration of the sequence. Flow rates were correlated with various clinical parameters. RESULTS Forty-five patients (22 non-IBD, 14 CD, 9 UC) were included in the study. Duodenal capillary flow rates were significantly higher in UC patients (0.75 ± 0.07 mm/s) as compared to non-IBD (0.57 ± 0.03) and CD (0.65 ± 0.04). There was no correlation between serum hemoglobin and albumin, disease activity indices, serum inflammatory markers, and capillary flow rates in patients. CONCLUSIONS This pilot study shows, for the first time, increased capillary blood flow in the duodenum of UC patients that was unrelated to inflammatory markers or disease activity. Thus, early vascular changes can be assessed using pCLE during endoscopy.

Abstract
Primary sclerosing cholangitis (PSC) is a rare obliterative fibrotic condition of the bile ducts. We assessed PSC epidemiology and natural history within the UK Clinical Practice Research Datalink (CPRD).Incidence and natural history of PSC were evaluated in a retrospective cohort study using linkage of CPRD, Hospital Episode Statistics, and Office for National Statistics data. Data from age, sex, and general practice-matched population controls provided a context for the incident PSC patients. Liver disease other than PSC was defined as autoimmune hepatitis, hepatitis, hepatomegaly, liver failure, cirrhosis, portal hypertension, cholangiocarcinoma, or hepatobiliary cancer.The age-standardized incidence of PSC was 0.68 (95% confidence interval [CI] 0.45-0.99) per 100,000 person-years and the age-standardized prevalence was 5.58 (95% CI 4.82-7.35) per 100,000 during 1998 to 2014. In all, 250 incident PSC patients met the inclusion criteria and each was matched with 5 controls (mean age 54 ± 18 years, men 63.2%). A higher percentage of PSC patients had a history of inflammatory bowel disease (54% vs 2%) and liver disease other than PSC (22% vs 1%) than controls (standardized differenceweighted >0.1). During a median follow-up of 5 years, PSC patients were more likely to develop adverse health outcomes. The mortality rate per 1000 person-years was 3-fold higher in PSC than population controls (49.5 vs 16.1; incidence rate ratio 3.1, 95% CI 2.2-4.2).The incidence and prevalence of PSC observed in the UK CPRD were either comparable with or higher than previous studies. Compared with the general population, PSC patients had worse health outcomes including PSC disease progression, complications, and higher mortality.

Abstract
BACKGROUND Anemia and iron deficiency are common complications of ulcerative colitis (UC). We aimed to develop and internally validate a prediction model for the incidence of moderate to severe anemia and iron deficiency anemia (IDA) in newly diagnosed patients with UC. METHODS Multivariable logistic regression was performed among a nationwide cohort of patients who were newly diagnosed with UC in the VA health-care system. Model development was performed in a random two-third of the total cohort and then validated in the remaining one-third of the cohort. As candidate predictors, we examined routinely available data at the time of UC diagnosis including demographics, medications, laboratory results, and endoscopy findings. RESULTS A total of 789 patients met the inclusion criteria. For the outcome of moderate to severe anemia, age, albumin level and mild anemia at UC diagnosis were predictors selected for the model. The AUC for this model was 0.69 (95% CI 0.64-0.74). For the outcome of moderate to severe anemia with evidence of iron deficiency, the predictors included African-American ethnicity, mild anemia, age, and albumin level at UC diagnosis. The AUC was 0.76, (95% CI 0.69-0.82). Calibration was consistently good in all models (Hosmer-Lemeshow goodness of fit p > 0.05). The models performed similarly in the internal validation cohort. CONCLUSIONS We developed and internally validated a prognostic model for predicting the risk of moderate to severe anemia and IDA among newly diagnosed patients with UC. This will help identify patients at high risk of these complications, who could benefit from surveillance and preventive measures.

Abstract
Background/Aims Inflammatory bowel disease (IBD) primarily involves the intestinal tract and can affect vitamin absorption. This study was designed to assess the prevalence of vitamin B12 and folate deficiencies in patients with IBD, and to identify the risk factors associated with abnormal serum vitamin B12 and folate levels. Methods We evaluated the medical records of 195 patients with Crohn's disease (CD) and 62 patients with ulcerative colitis (UC), and selected 118 healthy subjects for the control group. Results There were more CD patients with vitamin B12 deficiency than UC patients (14.9% vs. 3.2%, P=0.014) and controls (14.9% vs. 4.2%, P=0.003). The prevalence of folate deficiency was higher in CD patients than in controls (13.3% vs. 3.4%, P=0.004). There were no significant differences in the serum vitamin B12 and folate statuses of the UC and control groups. Patients with prior ileal or ileocolic resection showed a higher prevalence of abnormal vitamin B12 levels than those without prior resection (n=6/16, n=23/179; P=0.018). A disease duration within 5 years was a risk factor of abnormal folate levels in CD patients. Conclusions This study showed that vitamin B12 and folate deficiencies were more common in patients with CD than in UC patients and controls. Prior ileal or ileocolonic resection was a risk factor of serum vitamin B12 abnormalities, and a disease duration within 5 years was a risk factor of low serum folate levels in CD patients.

Abstract
Malnutrition is a major complication of inflammatory bowel disease (IBD). This mini review is focusing on main determinants of malnutrition in IBD, the most important components of malnutrition, including lean mass loss and sarcopenia, as an emerging problem. Each one of these components needs to be well considered in a correct nutritional evaluation of an IBD patient in order to build a correct multidisciplinary approach. The review is then focusing on possible instrumental and clinical armamentarium for the nutritional evaluation.

Anti-TNF-Mediated Modulation of Prohepcidin Improves Iron Availability in Inflammatory Bowel Disease, in an IL-6-Mediated Fashion. Can J Gastroenterol Hepatol 2017; 2017:6843976.

Abstract
Background. Anaemia is common in inflammatory bowel disease (IBD), frequently resulting from a combination of iron deficiency and of anaemia of chronic disease (ACD). ACD is characterized by macrophage iron retention induced by proinflammatory cytokines. Hepcidin is the master inducer of iron accumulation during ACD, and its production is mainly regulated by IL-6 and the novel erythroid hormone erythroferrone (ERFE). This study evaluates whether anti-TNF monoclonal antibodies therapy modurates hepcidin production and the levels of its main regulators, leading to a restoration of iron homeostasis. Methods. Sera were collected from 21 IBD patients, before each anti-TNF administration, for the first 6 weeks of therapy. Prohepcidin, erythropoietin, erythroferrone, C reactive protein, interleukin-6, iron markers, and haemoglobin levels were measured and clinical activity indexes were evaluated. Results. Serum prohepcidin, IL-6, CRP, and ferritin were significantly reduced after 6-week treatment; an increase in serum iron and total transferrin was observed. No changes in the EPO-ERFE axis were found. Remarkably, haemoglobin was significantly increased. Conclusions. Anti-TNF therapy improves iron metabolism and, subsequently, anaemia in IBD. This effect appears to be related to the modulation of the cytokine network and specifically IL-6 leading to a relevant decrease of hepcidin, a master regulator of ACD.

Abstract
OBJECTIVES Iron deficiency anemia (IDA) is common in children with inflammatory bowel disease (IBD) affecting their cognitive development and school performance. Oral iron supplementation has serious limitations including poor adherence and iron malabsorption related to chronic inflammation. Our objective was to evaluate the feasibility of periodic intravenous (IV) iron treatments for correction of IDA in children with IBD. METHODS This prospective study was conducted in 24 children with IBD treated with infliximab (IFX). Participants received 3 mg/kg (maximum 200 mg) IV iron sucrose (IS) after IFX treatments if they were iron deficient according to criteria: ferritin <30 ng/mL or transferrin saturation (TSAT) <20% with normal C-reactive protein (CRP), or ferritin <100 ng/mL and TSAT <20% with elevated CRP. They continued to receive IV IS with each IFX treatment until 2 consecutive laboratories showed no evidence of iron deficiency. Hematology and iron indices obtained during the study were compared with historic controls from the same patients. RESULTS Mean ferritin, TSAT, and hemoglobin (Hb) (±SE) rose from 21.9 (±3.2) to 48.8 (±6.3) ng/mL (P = 0.0004), 13.2 (±1.8) to 23.6 (±2.6)%, (P = 0.0009) and 11.4 (±0.3) to 12.7 (±0.3) g/dL, (P = 0.006) respectively. The proportion of patients with normal mean ferritin, TSAT, and Hb rose from 33% to 75% (P = 0.002), 21% to 63% (P = 0.006), and 25% to 79% (P = 0.0002), respectively. There were no adverse reactions. CONCLUSIONS Periodic IV IS is safe and effective for routine management of IDA in children with IBD.

Abstract
Anemia affects a fourth of the global population, with iron deficiency remaining the primary cause. It is associated with diminished work capacity, fatigue, impaired cognitive function, and can negatively impact the course of diseases like chronic heart failure or chronic kidney disease. Treatment options include oral and intravenous iron; however, conditions such as inflammatory bowel disease, celiac disease, or autoimmune gastritis can diminish the efficacy of oral iron. Timely recognition of iron deficiency anemia and administration of appropriate therapy not only improves quality of life, but also reduces the need for blood transfusions. Proper selection of iron-deficient patients for whom further diagnostic testing is necessary facilitates identification of underlying diseases that require specific treatment, and avoids unnecessary invasive testing.

Abstract
In recent decades, the prevalence of ulcerative colitis (UC) presents a gradually upward trend. A considerable part of UC patients with anemia have dizziness, fatigue, chest tightness, heart palpitations and other symptoms. Anemia is one of the common complications of UC. Studies indicate that the severity of anemia is related to the degree of activity of UC. Compared with other extra-intestinal complications, most experts believe that anemia is inevitable in UC. Since anemia can affect the quality of life, cognitive ability, work ability and therapeutic effect, early diagnosis and active treatment of anemia in patients with UC can improve the outcomes of patients. Here we review the recent progress in the diagnosis and treatment of UC with anemia by traditional Chinese medicine combined with Western medicine.

Abstract
BACKGROUND AND AIMS We sought to correlate hepcidin levels in inflammatory bowel disease [IBD] children with disease activity, inflammatory markers, and iron load test [ILT] and to compare IBD patients with coeliac and healthy patients. METHODS Between December 2012 and June 2013, 145 subjects [50 IBD patients, 45 coeliac patients and 50 healthy controls] were included in the study. All patients underwent the following examinations: blood count, iron status, erythropoiesis parameters, serum hepcidin, C-reactive protein [CRP], and erythrocyte sedimentation rate [ESR]. In order to evaluate the efficacy of iron absorption, ILT was performed in IBD patients. Disease activity indexes and IBD duration, localisation, and therapy were also evaluated, and a faecal sample for calprotectin collected. RESULTS Serum hepcidin was significantly higher in IBD patients with active disease compared with both coeliac and healthy patients [p = 0.005, p = 0.003 respectively]. In a multivariate logistic regression model, having a Paediatric Crohn's Disease Activity Index [PCDAI] / Paediatric Ulcerative Colitis Activity Index [PUCAI] ≥ 30 resulted in the only variable independently associated with a positive serum hepcidin (odds ratio [OR] = 6.87; 95% confidence interval [CI] 1.4-33, p = 0.01]]. Patients with iron malabsorption [IM] showed higher values of ESR, CRP, and hepcidin [p = 0.02, p = 0.001, and p = 0.06, respectively]. Eight out of 12 [66.7%] children with IM showed an active disease compared with 6/31 [19.3%] children with normal ILT [p = 0.01]. Hepcidin levels correlated negatively with ILT [r = -0.451, p = 0.002], and positively with ferritin and CRP [r = 0.442, p = 0.0001; r = 0.243, p = 0.009, respectively] CONCLUSIONS Our study demonstrates that serum hepcidin is increased in IBD children with active disease and it is responsible for IM.

ARQUIVOS DE GASTROENTEROLOGIA 2015; 52:255-9. [DOI: 10.1590/s0004-28032015000400002] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Accepted: 09/09/2015] [Indexed: 12/16/2022]
Abstract
Objectives - Anemia is the most common hematological alteration in patients with Crohn's disease, and is frequently related to intestinal inflammatory activity. Its cause is multifactorial and mostly associated with absolute iron deficiency (iron deficiency anemia) and/or functional iron deficiency (inflammation anemia or anemia of chronic disease). It may also be identified through other causes, such as folic acid or vitamin B12 deficiency and secondary to adverse effects from medications (salicylic derivatives and immunosuppressive drugs). In the present study, patients with active Crohn's disease and anemia were evaluated and treated with intravenous ferric carboxymaltose. We discuss the therapeutic schemes (doses), safety, results and improvement of quality of life. Methods - In the present prospective study, 10 consecutive patients with Crohn's disease, with moderate to severe activity, with anemia (Hb: 6.7 to 10 g/dL), who were attended between March 2014 and March 2015, were evaluated. Six (60%) were men and four were women, all with moderate or severe anemia (hemoglobin <10 g/dL). They were treated with a maximum of three intravenous infusions of 1000 mg of ferric carboxymaltose, of at least 15 minutes in duration. It was also sought to correlate the inflammatory Crohn's disease activity degree (measured using the Crohn's Disease Activity Index, CDAI) and C-reactive protein level with the severity of anemia. The primary outcome was an increase in Hb of ≥2 g/dL and the secondary outcome was the normalization of anemia (Hb ≥12 g/dL for women and ≥13 g/dL for men) and the improvement in quality of life seen 12 weeks after the last application of carboxymaltose. Results - Among the 10 patients studied, parenteral iron supplementation was administered in three cases during hospitalization and the others received this on an outpatient basis. The total iron dose ranged from 1,000 to 2,000 mg, with an average of 1,650 mg. Crohn's disease activity measured using CDAI and C-reactive protein correlated with the intensity of anemia. An increase of 2 g/dL occurred in eight (80%) patients after 12 weeks and normalization of anemia was found in seven (70%) patients. Improvements in quality-of-life scores were found for all (100%) patients after 12 weeks. Carboxymaltose was well tolerated. Three patients presented adverse reactions (two with nausea and one with headache) of mild intensity. Conclusions - Anemia is a frequent complication for Crohn's disease patients. Intravenous iron therapy has been recommended for Crohn's disease patients, because for these patients, oral iron absorption is very limited. This is because of the inflammatory state and "blocking" of iron entry into enterocytes through hepcidin action on ferroportin, along with the elevated rates of gastrointestinal adverse events that compromise adherence to treatment and possibly aggravate the intestinal inflammatory state. The degree of Crohn's disease activity, as measured using CDAI and C-reactive protein, correlates with the severity of anemia. Carboxymaltose is a safe drug, which can be administrated in high doses (up to 1,000 mg per application per week) and corrects anemia and iron stocks over a short period of time, with consequent improvement in quality of life.

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
Anemia is the most frequent complication of inflammatory bowel disease (IBD), but anemia, mostly due to iron deficiency, has long been neglected in these patients. The aim was to briefly present the pathophysiology, followed by a balanced overview of the different forms of iron replacement available, and subsequently, to perform a systematic review of studies performed in the last decade on the treatment of iron-deficiency anemia in IBD. Given that intravenous therapies have been introduced in the last decade, a systematic review performed in PubMed, EMBASE, the Cochrane Library, and the websites of WHO, FDA, and EMA covered prospective trials investigating the management of iron-deficiency anemia in IBD published since 2004. A total of 632 articles were reviewed, and 13 articles (2906 patients) with unique content were included. In general, oral supplementation in iron-deficiency anemia should be administered with a target to restore/replenish the iron stores and the hemoglobin level in a suitable way. However, in patients with IBD flares and inadequate responses to or side effects with oral preparations, intravenous iron supplementation is the therapy of choice. Neither oral nor intravenous therapy seems to exacerbate the clinical course of IBD, and intravenous iron therapy can be administered even in active disease stages and concomitantly with biologics. In conclusion, because many physicians are in doubt as to how to manage anemia and iron deficiency in IBD, there is a clear need for the implementation of evidence-based recommendations on this matter. Based on the data presented, oral iron therapy should be preferred for patients with quiescent disease stages and trivial iron deficiency anemia unless such patients are intolerant or have an inadequate response, whereas intravenous iron supplementation may be of advantage in patients with aggravated anemia or flares of IBD because inflammation hampers intestinal absorption of iron.

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

Abstract
Background: Nutritional deficiency, bleeding, and inflammation are three main causes of anemia. On the other hand, erythropoietin (EPO) production, iron availability, and a healthy bone marrow are essential for erythropoiesis. Recently, recombinant human erythropoietin (rhEPO) has been used to treat the patients already taking iron supplements. In Iranian traditional medicine literature, much has been written about anemia and its treatment. Objectives: This study aimed to review Iranian traditional medicine theories in the treatment of anemia. Materials and Methods: In the present study, authors have attempted to find the etiology and pathogenesis of anemia in Iranian traditional Medicine Literature and the views of ancient physicians in this field. Results: Our findings proved that Iranian traditional medicine defined anemia as blood humor production dysfunction, which is caused by several reasons mainly hepatic dysfunction. Thus, liver is supposed to be the most important organ in this regard. This will make considering hepatoprotective medicines in anemia even in patients with non-hepatic problems. Conclusions: The article presents the relation between anemia and liver dysfunction viewed by Iranian traditional medicine as an important finding in designing a treatment plan. Despite the new findings on the evaluation of liver function (i.e. laboratory tests), it seems that further studies for earlier evaluation of liver function in anemia are highly required.

Abstract
BACKGROUND AND AIMS Anemia is a frequent complication of inflammatory bowel disease (IBD). Hepcidin, a key mediator in this anemia, is up-regulated by high iron levels and inflammation, and serum levels are elevated in IBD. However, the extent of inflammatory activity and iron deficiency for the regulation of hepcidin is not known. This study aimed to evaluate serum hepcidin levels in anemic and non-anemic IBD patients, with iron or non-iron deficiency, and active or inactive disease. METHODS This retrospective, observational study analyzed serum hepcidin levels from 247 patients with IBD (130 Crohn's patients and 117 with ulcerative colitis) recruited at Swiss Inflammatory Bowel Disease Cohort Study centers. Patients were divided into 5 different groups using criteria of active and inactive diseases (C-reactive protein, and CDAI/MTWAI=disease activity-index), anemia (hemoglobin) and iron deficiency (ferritin) and compared to healthy controls with no signs of anemia and normal ferritin levels. Hepcidin was measured using enzyme-linked immunosorbent assay. RESULTS Independent of inflammatory activity, all patients with decreased ferritin (<30μg/L) had significantly lower hepcidin levels when compared to patients and healthy controls having normal ferritin (>30μg/L). A significant correlation between serum ferritin levels and serum hepcidin was found (Spearman's Rho=0.491; p<0.001). A backward multi-linear stepwise regression analysis showed that only ferritin, and none of the inflammatory markers or age and sex correlated significantly (p=0.005) with hepcidin. CONCLUSION This retrospective analysis suggests that iron deficiency is the key trigger for hepcidin regulation in IBD patients with anemia.

Abstract
UNLABELLED Inflammatory bowel diseases (IBDs) are chronic and progressive inflammatory disorders of the gastrointestinal tract. In IBD, protein serological biomarkers could be relevant tools for assessing disease activity, performing early-stage diagnosis and managing the treatment. Using the interleukin-10 knockout (IL-10(-/-)) mouse, a model that develops a time-dependent IBD-like disorder that predominates in the colon; we performed longitudinal studies of circulating protein biomarkers in IBD. Circulating protein profiles in serum samples collected from 30-, 93-, to 135-day-old IL-10(-/-) mice were investigated using two-dimensional differential gel electrophoresis and MALDI-TOF/TOF tandem mass spectrometry. A total of 15 different proteins were identified and confirmed by ELISA and Western blot to be differentially accumulated in serum samples from mid- to late-stage IL-10(-/-) mice compared to early non-inflamed IL-10(-/-) mice. The use of another model of colitis and an extra-intestinal inflammation model validated this biomarker panel and demonstrated that comprised some global inflammatory markers, some intestinal inflammation-specific markers and some chronic intestinal inflammation markers. Statistical analyses using misclassification error rate charts validated the use of these identified proteins as powerful biomarkers of colitis. Unlike standard biomarker screening studies, our analyses identified a panel of proteins that allowed the definition of protein signatures that reflect colitis status. BIOLOGICAL SIGNIFICANCE Crohn's disease (CD) and ulcerative colitis (UC) are the most common inflammatory bowel diseases (IBDs) occurring in humans. The major current diagnosis tool is colonoscopy, which is invasive and could lead to false diagnosis. The emergence of serological biomarkers enables the use of new diagnosis tools such as protein signatures for IBD diagnosis/management. Using 2D-DIGE coupled to mass spectrometry, our longitudinal study in a mouse model of colitis identified a signature of protein biomarkers for specific stages of disease.

Abstract
CONTEXT AND OBJECTIVES Anemia is the most frequent extraintestinal complication of inflammatory bowel disease. This study aimed to: 1) determine the prevalence of anemia among patients with inflammatory bowel disease; 2) investigate whether routine laboratory markers are useful for diagnosing anemia; and 3) evaluate whether any association exists between anemia and clinical/laboratory variables. DESIGN AND SETTING Cross-sectional at a federal university. METHODS 44 outpatients with Crohn's disease and 55 with ulcerative colitis were evaluated. Clinical variables (disease activity index, location of disease and pharmacological treatment) and laboratory variables (blood count, iron laboratory, vitamin B12 and folic acid) were investigated. RESULTS Anemia and/or iron laboratory disorders were present in 75% of the patients with Crohn's disease and in 78.2% with ulcerative colitis. Anemia was observed in 20.5% of the patients with Crohn's disease and in 23.6% with ulcerative colitis. Iron-deficiency anemia was highly prevalent in patients with Crohn's disease (69.6%) and ulcerative colitis (76.7%). Anemia of chronic disease in combination with iron deficiency anemia was present in 3% of the patients with Crohn's disease and in 7% of the patients with ulcerative colitis. There was no association between anemia and disease location. In ulcerative colitis, anemia was associated with the disease activity index. CONCLUSIONS Most patients present iron laboratory disorders, with or without anemia, mainly due to iron deficiency. The differential diagnosis between the two most prevalent types of anemia was made based on clinical data and routine laboratory tests. In ulcerative colitis, anemia was associated with the disease activity index.

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.

The variation is probably due to differences in the definition of anaemia and the study populations. AIM To retrospectively determine the prevalence of anaemia at diagnosis and at the 1-, 5- and 10-year follow-ups in patients with IBD from a prospectively followed, population-based inception cohort (the IBSEN Study). To compare the prevalence of anaemia after a 10-year disease course with the prevalence of anaemia in the background population, and to assess clinical factors associated with anaemia at diagnosis and during follow-up. METHODS Newly diagnosed IBD patients were included in a population-based, prospective cohort. Follow-up was performed at 1, 5 and 10 years. All visits included clinical examinations and blood samples. Anaemia was defined according to the WHO. RESULTS A total of 756 patients (UC, n = 519 and CD, n = 237) were included; 48.8% of CD and 20.2% of UC patients were anaemic at diagnosis (P < 0.001). The proportion of patients with anaemia decreased during the disease course in all patients, except in women with CD. After 10 years of disease, the relative risk for anaemia was increased in all groups, except for women with UC. The variables associated with anaemia were generally unchanged during the disease course, and elevated CRP was the strongest predictor of risk. CONCLUSIONS Anaemia was more common in CD than in UC. The prevalence of anaemia decreased during the disease course. Women with CD were at high risk for anaemia. Elevated CRP was independently associated with anaemia.

Abstract
BACKGROUND Iron deficiency is a common and undertreated problem in inflammatory bowel disease (IBD). AIM To develop an online tool to support treatment choice at the patient-specific level. METHODS Using the RAND/UCLA Appropriateness Method (RUAM), a European expert panel assessed the appropriateness of treatment regimens for a variety of clinical scenarios in patients with non-anaemic iron deficiency (NAID) and iron deficiency anaemia (IDA). Treatment options included adjustment of IBD medication only, oral iron supplementation, high-/low-dose intravenous (IV) regimens, IV iron plus erythropoietin-stimulating agent (ESA), and blood transfusion. The panel process consisted of two individual rating rounds (1148 treatment indications; 9-point scale) and three plenary discussion meetings. RESULTS The panel reached agreement on 71% of treatment indications. 'No treatment' was never considered appropriate, and repeat treatment after previous failure was generally discouraged. For 98% of scenarios, at least one treatment was appropriate. Adjustment of IBD medication was deemed appropriate in all patients with active disease. Use of oral iron was mainly considered an option in NAID and mildly anaemic patients without disease activity. IV regimens were often judged appropriate, with high-dose IV iron being the preferred option in 77% of IDA scenarios. Blood transfusion and IV+ESA were indicated in exceptional cases only. CONCLUSIONS The RUAM revealed high agreement amongst experts on the management of iron deficiency in patients with IBD. High-dose IV iron was more often considered appropriate than other options. To facilitate dissemination of the recommendations, panel outcomes were embedded in an online tool, accessible via http://ferroscope.com/.
