Abstract
PURPOSE Iron deficiency anemia (IDA) is the most common form of anemia worldwide, resulting in a high burden of disease. Accumulating evidence suggests that IDA is associated with the development of gastrointestinal (GI) cancers. METHODS Data from the IDA database (IQVIA) of primary care practices in Germany of adult patients first diagnosed with IDA between January 2005 and December 2021 were retrospectively analyzed and compared with a 1:1 propensity score-adjusted cohort without IDA. Study outcomes were first stomach cancer or colorectal cancer (CRC) diagnosis up to 10 years after the index date as a function of IDA. RESULTS A total of 122,502 individuals with IDA and 122,502 individuals without IDA were included. The 10-year cumulative incidence of CRC was 1.4% in the IDA patients compared to 0.8% in the cohort without IDA (p < 0.001). Regression analysis revealed a significant association between IDA and subsequent CRC (HR 2.05; 95% CI 1.83-2.30). Stomach cancer was diagnosed in 0.3% of IDA patients compared to 0.2% in the non-IDA cohort during the 10-year follow-up period (p = 0.002). However, this was significant only in the age group > 80 years (HR 2.73; 95% CI 1.60-4.67) and in men (HR 1.90; 95% CI 1.38-2.61). CONCLUSION These findings add to the literature and suggest an association between IDA and GI cancers. The extent to which this association is due to GI bleeding or other pathophysiological processes that may be caused by IDA requires further investigation, particularly experimental studies.

Prevalence of gastrointestinal malignancy in non-anemic iron deficiency and significance for endoscopic screening: A Western Australian multicenter cohort study. J Gastroenterol Hepatol 2023; 38:1530-1534. [PMID: 37198146 DOI: 10.1111/jgh.16215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Revised: 04/25/2023] [Accepted: 04/28/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND AND AIM There is a paucity of evidence regarding non-anemic iron deficiency as a predictor for colorectal cancer and therefore the indication for endoscopic evaluation. This study explores the rates of malignancy in adults with iron deficiency with and without anemia. METHODS A retrospective multicenter diagnostic cohort study was conducted across two Australian health services. All cases that underwent both esophagogastroduodenoscopy and colonoscopy between September 1, 2018, and December 31, 2019, for the investigation of iron deficiency were included, and the cohort was divided into anemic and non-anemic arms. Multivariate binomial logistic regression was performed to establish clinical characteristics associated with neoplasia. RESULTS Five hundred eighty-four patients underwent endoscopic evaluation over a 16-month period. There was a significantly higher rate of malignancy in the iron deficiency anemia arm as compared with those without anemia (8.76% vs 1.20%, P < 0.01). Gastrointestinal pathology to account for iron deficiency was identified in > 60% of the total cohort. The presence of anemia (odds ratio [OR] 6.87, P < 0.01) and male gender (OR 3.01, P = 0.01) were significant predictors of malignancy. CONCLUSION This study demonstrates that anemic iron deficiency confers a significantly greater risk of gastrointestinal cancer compared with non-anemic iron deficiency. Additionally, over 60% of patients had gastrointestinal pathology to account for iron deficiency overall, supporting the need to perform baseline endoscopy in patients with iron deficiency.

Abstract
BACKGROUND AND AIMS Bleeding from the gastrointestinal tract can contribute to the development of iron deficiency anemia (IDA) among individuals without another obvious source of bleeding. In order to identify patients most likely to benefit from examination of the small bowel, our aim was to create a risk score for positive video capsule endoscopy (VCE) in IDA utilizing a multicenter collection of studies. METHODS We performed a retrospective multicenter study utilizing VCE studies performed for an indication of IDA between 1/1/2005 and 7/31/2018. VCE findings were graded based on the P0-P2 grading system. The primary outcome of interest was a positive (P2) VCE. Data were analyzed with Student's t test for continuous variables and the Fisher's exact test for categorical variables. Logistic regression was used to identify independent associations with positive VCE. RESULTS In total, 765 VCE procedures were included with 355 (46.5%) male subjects and a median age of 63.2 (SD 15.3) years. One hundred ninety studies (24.8%) were positive (P2) for small bowel bleeding. Four variables associated with positive VCE which were incorporated into a point scoring system: (+) 1 for age ≥ 66 years, active smoking and cardiac arrythmia and (-) 1 for preceding hemoglobin level ≥ 8.5. The risk probabilities for positive VCE-assigned scores - 1, 0, 1, and 2 + were 12.3% (95% CI 7.3-17.3%), 20% (14.9-25.1%), 34.8% (28.6-41%), and 39% (30-47.8%). CONCLUSION In order to improve the diagnostic yield of capsule examinations, risk factors should be applied to clinical decision-making. We created a risk score for positive VCE in IDA, including the risk factors of age, smoking, history of cardiac arrythmia, and preceding hemoglobin level.

Abstract
BACKGROUND Childhood cancer may be related to maternal health in pregnancy. Maternal anemia is a common condition in pregnancy, especially in low-income countries, but the association between maternal anemia and childhood cancer has not been widely studied. OBJECTIVE To examine the potential relation between maternal anemia during pregnancy and childhood cancers in a population-based cohort study in Taiwan. METHODS We examined the relationship between maternal anemia and childhood cancer in Taiwan (N = 2160 cancer cases, 2,076,877 noncases). Cases were taken from the National Cancer Registry, and noncases were selected from birth records. Using national health registries, we obtained maternal anemia diagnoses. We estimated the risks for childhood cancers using Cox proportional hazard analysis. RESULTS There was an increased risk of cancers in children born to mothers with nutritional anemia (hazard ratio (HR): 1.32, 95% CI 0.99, 1.76). Iron deficiency anemia (HR: 1.30, 95% CI 0.97-1.75) carried an increased risk, while non-nutritional anemias were not associated with childhood cancer risk. CONCLUSION Our results provide additional support for screening for anemia during pregnancy. Adequate nutrition and vitamin supplementation may help to prevent some childhood cancer.

Small Bowel Malignancies in Patients Undergoing Capsule Endoscopy for Iron Deficiency Anemia. Diagnostics (Basel) 2021; 12:diagnostics12010091.

Abstract
Small bowel malignancies are rare and usually asymptomatic or symptoms are nonspecific. Therefore, small bowel tumors are difficult to diagnose. In patients with iron deficiency anemia (IDA) who have negative bidirectional endoscopy results, the small bowel may be considered the source of bleeding. However, in asymptomatic IDA patients with negative bidirectional endoscopy results, evidence supporting the routine use of capsule endoscopy (CE) is insufficient. CE can be considered in selected patients with recurrent or persistent IDA. The frequency of small bowel malignancies is low in patients undergoing CE for IDA, but the usefulness of CE for the diagnosis of small bowel malignancies in younger age groups with IDA has been reported. For patients with risk factors for small bowel malignancy, investigation of the small bowel should be considered. Efforts should be made to prevent adverse events, such as capsule retention or capsule aspiration, through meticulous history taking and endoscopic capsule delivery as necessary.

Abstract
Iron deficiency anaemia (IDA) is a major cause of morbidity and burden of disease worldwide. It can generally be diagnosed by blood testing and remedied by iron replacement therapy (IRT) using the oral or intravenous route. The many causes of iron deficiency include poor dietary intake and malabsorption of dietary iron, as well as a number of significant gastrointestinal (GI) pathologies. Because blood is iron-rich it can result from chronic blood loss, and this is a common mechanism underlying the development of IDA-for example, as a consequence of menstrual or GI blood loss.Approximately a third of men and postmenopausal women presenting with IDA have an underlying pathological abnormality, most commonly in the GI tract. Therefore optimal management of IDA requires IRT in combination with appropriate investigation to establish the underlying cause. Unexplained IDA in all at-risk individuals is an accepted indication for fast-track secondary care referral in the UK because GI malignancies can present in this way, often in the absence of specific symptoms. Bidirectional GI endoscopy is the standard diagnostic approach to examination of the upper and lower GI tract, though radiological scanning is an alternative in some situations for assessing the large bowel. In recurrent or refractory IDA, wireless capsule endoscopy plays an important role in assessment of the small bowel.IDA may present in primary care or across a range of specialties in secondary care, and because of this and the insidious nature of the condition it has not always been optimally managed despite the considerable burden of disease- with investigation sometimes being inappropriate, incorrectly timed or incomplete, and the role of IRT for symptom relief neglected. It is therefore important that contemporary guidelines for the management of IDA are available to all clinicians. This document is a revision of previous British Society of Gastroenterology guidelines, updated in the light of subsequent evidence and developments.

Abstract
Background Blood loss from the gastrointestinal (GI) tract is the most common cause of iron deficiency anaemia (IDA) in adult men and postmenopausal women. Gastroduodenal endoscopy (GDE) and colonoscopy are frequently recommended, despite uncertainty regarding the coexistence of lesions in the upper and lower GI tract. The faecal immunochemical test (FIT) measures the concentration of faecal haemoglobin (f-Hb) originating only from the colon or rectum. We aimed to assess whether the FIT was able to select the best endoscopic procedure for detecting the cause of IDA. Methods A prospective study of 120 men and postmenopausal women referred for a diagnostic study of IDA were evaluated with an FIT, GDE and colonoscopy. The endoscopic finding of a significant upper lesion (SUL) or a significant bowel lesion (SBL) was considered to be the cause of the IDA. Results The diagnoses were 35.0% SUL and 20.0% SBL, including 13.3% GI cancer. In the multivariate analysis, the concentration of blood haemoglobin (b-Hb) <9 g/dL (OR: 2.60; 95% CI 1.13-6.00; p = 0.025) and non-steroidal anti-inflammatory drugs NSAIDs (2.56; 1.13-5.88; p = 0.024) were associated with an SUL. Age (0.93; 0.88-0.99; p = 0.042) and f-Hb ≥ 15 μg Hb/g faeces (38.53; 8.60-172.50; p < 0.001) were associated with an SBL. A "FIT plus gastroscopy" strategy, in which colonoscopy is performed only when f-Hb ≥15 μg Hb/g faeces, would be able to detect 92.4% of lesions and be 100% accurate in the detection of cancer while avoiding 71.6% of colonoscopies. Conclusions The FIT is an accurate method for selecting the best endoscopy study for the evaluation of IDA. An FIT-based strategy is more cost-effective than the current bidirectional endoscopy-based strategy and could improve endoscopic resource allocation.

Abstract
Iron deficiency, with or without anemia, is the most frequent hematological manifestation in individuals with cancer, and is especially common in patients with colorectal cancer. Iron is a vital micronutrient that plays an essential role in many biological functions, in the context of which it has been found to be intimately linked to cancer biology. To date, however, whereas a large number of studies have comprehensively investigated and reviewed the effects of excess iron on cancer initiation and progression, potential interrelations of iron deficiency with cancer have been largely neglected and are not well-defined. Emerging evidence indicates that reduced iron intake and low systemic iron levels are associated with the pathogenesis of colorectal cancer, suggesting that optimal iron intake must be carefully balanced to avoid both iron deficiency and iron excess. Since iron is vital in the maintenance of immunological functions, insufficient iron availability may enhance oncogenicity by impairing immunosurveillance for neoplastic changes and potentially altering the tumor immune microenvironment. Data from clinical studies support these concepts, showing that iron deficiency is associated with inferior outcomes and reduced response to therapy in patients with colorectal cancer. Here, we elucidate cancer-related effects of iron deficiency, examine preclinical and clinical evidence of its role in tumorigenesis, cancer progression and treatment response. and highlight the importance of adequate iron supplementation to limit these outcomes.

[PMID: 34966529 PMCID: PMC8666872 DOI: 10.1136/flgastro-2020-101470] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2020] [Revised: 08/03/2020] [Accepted: 08/11/2020] [Indexed: 02/04/2023] Open
Abstract
OBJECTIVE To report our cumulative experience from a dedicated iron deficiency anaemia (IDA) clinic over the last 15 years-with particular emphasis on referral rate, uptake of investigation, impact on endoscopy services, diagnostic yield of gastrointestinal (GI) investigation and the issue of recurrent IDA. METHOD A series of analyses of a register of 2808 referrals to the Poole IDA clinic between 2004 and 2018. RESULTS The study population of 2808 had a sex ratio of 1.9 (female/male ratio) and a median age of 72 years (IQR: 60-79). A rising referral rate over the study period appears to be plateauing at around 2 cases per 1000 population per annum. On the basis of a snapshot audit, investigation of IDA may now account for over 20% of all diagnostic endoscopies.Overall, 86% of cases underwent examination of the upper and lower GI tract. Significant GI pathology was identified in 27% of the investigated cohort. Adenocarcinoma of the upper or lower GI tract was found in 8.3%, the majority in the right colon. The prevalence of recurrent IDA was estimated at 12.4%, and the results of investigation of this subgroup are reported. CONCLUSION Unexplained IDA is common, particularly in those over 60 years, and may be the first indication of underlying GI malignancy in over 8% of cases. Unresolved challenges include accommodating the resulting endoscopy workload, establishing a risk/benefit ratio for investigating those with major comorbidities and the management of recurrent IDA.

Abstract
Introduction The diagnosis of iron deficiency anemia (IDA) relies heavily on symptom presentation, and patients lacking typical gastrointestinal (GI) symptoms represent a diagnostic challenge. IDA may be the initial manifestation of underlying pathology. This study sought to evaluate the effectiveness of different GI endoscopic studies in patients with IDA who lack GI symptoms. Methods We conducted an observational, multicenter retrospective analysis of 398 asymptomatic IDA patients admitted for GI endoscopic diagnosis from 2006 to 2016. Baseline measurements included hemoglobin, serum ferritin, mean corpuscular volume, serum iron, total iron-binding capacity, and transferrin saturation. We analyzed demographic characteristics, duration of hospital stay, the degree of severity of anemia, and endoscopic findings. Results The mean age of the study population was 52±9 years (range, 23 to 85 years), and 53% were men. Most patients were older than 45 years (n=353, 89%) with mild to moderate IDA. Patients underwent esophagogastroduodenoscopy (EGD, n=102), colonoscopy (n=271), or bidirectional endoscopy (n=25). The mean hospital stay was 2.72±1.66 days. The most common EGD results were atrophic gastritis (n=31), peptic ulcer (n=25), and negative findings (n=25). The most common colonoscopic results were negative findings (n=118), nonspecific colonic inflammatory changes (n=117), and non-bleeding hemorrhoids (n=29). We found no significant association between any endoscopic findings and age, gender, the severity of anemia, and length of hospitalization. Conclusions The presence of symptoms is of limited value in guiding diagnostic procedures concerning GI etiologies. Asymptomatic patients with IDA patients should receive an endoscopic examination irrespective of iron parameters, age, or gender for potentially treatable pathologies, especially for patients with suspected malignancies.

Abstract
Introduction: Iron deficiency anemia (IDA) is a risk factor for gastrointestinal (GI) malignancies. Little is known regarding the correlation between the depth of anemia and the risk for GI malignancy. The aim of this study was to test the hypothesis that very low hemoglobin levels pose an additional risk compared to low hemoglobin levels.Methods: Patients 40-70 years old, presenting to the ER with IDA during years 2016-2017 were retrospectively analyzed. Comparison was performed between two groups, one with a very low hemoglobin level (below 8 g/dL) and the other a low hemoglobin level (between 8-10 g/dL).Results: 1020 patients were analyzed, and 107 fulfilled the inclusion criteria. Seventy-five patients (70%) were in the very low hemoglobin group and 21 patients (19.6%) were diagnosed with a new GI malignancy. Mean age was 56, 49 (45%) were females, and 68 (63%) underwent esophagogastroduodenoscopy (EGD) or/and colonoscopy during the index hospitalization. The median hemoglobin and MCV were 7.3 G/dL, and 73 fL, respectively. New malignancies were found in 15/75 (20%) and 6/32 (19%) of patients with very low and low hemoglobin levels, respectively (p = .88). GI malignancies were more commonly found in females compared to males, 14 (29%) vs. 7 (12%), p = .032, respectively. The right colon was the most common site for malignancy. Active GI bleeding was not a risk factor for GI malignancy.Conclusions: Very low hemoglobin levels and overt GI bleeding do not pose an additional risk factor for GI malignancy, compared to low hemoglobin levels and no overt GI bleeding.

Abstract
There is a growing body of evidence on the incidence and negative prognostic impact of postdischarge hemorrhagic complications after an acute coronary syndrome (ACS). However, the risk of subsequent cancer after postdischarge bleeding in these patients is currently poorly known. The aim of this study was to assess the association of postdischarge bleeding with newly diagnosed cancers after an ACS. Data from a single-center registry of 3,644 ACS patients, who were discharged with dual antiplatelet therapy and treated with percutaneous coronary intervention, were used to investigate the association between postdischarge bleeding and diagnosis of cancer. During a median follow-up of 56.2 months, bleeding events were documented in 1,216 patients and newly diagnosed cancers in 227 patients. Postdischarge bleeding was associated with cancer diagnosis (adjusted hazard ratio [HR] 3.43, 95% confidence interval [CI] 2.62 to 4.50), but only spontaneous bleeding (adjusted HR 4.38, 95% CI 3.31 to 5.79). This association was stronger as the severity of the bleeding increased (HR 1.52, 4.88, 7.30, and 12.29, for BARC type 1, 2, 3a, and 3b bleeding, respectively). Positive predictive values for cancer diagnosis of postdischarge bleeding was 7.7%. Median time from bleeding to cancer was 4.6 months. In conclusion, spontaneous postdischarge bleeding in ACS patients is strongly associated with subsequent cancer diagnosis within the first 6 months. A prompt evaluation of bleeding could be useful for enabling an early detection of cancer in these patients.

Abstract
OBJECTIVE To refine and validate a model for predicting the risk of gastrointestinal (GI) cancer in iron deficiency anaemia (IDA) and to develop an app to facilitate use in clinical practice. DESIGN Three elements: (1) analysis of a dataset of 2390 cases of IDA to validate the predictive value of age, sex, blood haemoglobin concentration (Hb), mean cell volume (MCV) and iron studies on the probability of underlying GI cancer; (2) a pilot study of the benefit of adding faecal immunochemical testing (FIT) into the model; and (3) development of an app based on the model. RESULTS Age, sex and Hb were all strong, independent predictors of the risk of GI cancer, with ORs (95% CI) of 1.05 per year (1.03 to 1.07, p<0.00001), 2.86 for men (2.03 to 4.06, p<0.00001) and 1.03 for each g/L reduction in Hb (1.01 to 1.04, p<0.0001) respectively. An association with MCV was also revealed, with an OR of 1.03 for each fl reduction (1.01 to 1.05, p<0.02). The model was confirmed to be robust by an internal validation exercise. In the pilot study of high-risk cases, FIT was also predictive of GI cancer (OR 6.6, 95% CI 1.6 to 51.8), but the sensitivity was low at 23.5% (95% CI 6.8% to 49.9%). An app based on the model was developed. CONCLUSION This predictive model may help rationalise the use of investigational resources in IDA, by fast-tracking high-risk cases and, with appropriate safeguards, avoiding invasive investigation altogether in those at ultra-low predicted risk.

Abstract
Iron deficiency anaemia (IDA) is common in older adults and associated with a range of adverse outcomes. Differentiating iron deficiency from other causes of anaemia is important to ensure appropriate investigations and treatment. It is possible to make the diagnosis reliably using simple blood tests. Clinical evaluation and assessment are required to help determine the underlying cause and to initiate appropriate investigations. IDA in men and post-menopausal females is most commonly due to occult gastrointestinal blood loss until proven otherwise, although there is a spectrum of underlying causative pathologies. Investigation decisions should take account of the wishes of the patient and their competing comorbidities, individualising the approach. Management involves supplementation using oral or intravenous (IV) iron then consideration of treatment of the underlying cause of deficiency. Future research areas are outlined including the role of Hepcidin and serum soluble transferrin receptor measurement, quantitative faecal immunochemical testing, alternative dosing regimens and the potential role of IV iron preparations.

Abstract
BACKGROUND Iron deficiency anaemia is associated with gastrointestinal (GI) malignancy and is an indication for GI investigations. However, the relevance of iron deficiency without anaemia (IDWA) and the underlying risks of GI malignancy are uncertain. Therefore, the aim of this study was to estimate the prevalence of GI malignancy in patients with IDWA overall and in clinically relevant subgroups. METHODS We searched MEDLINE and EMBASE for studies that reported on the prevalence or risk of GI malignancy in patients with confirmed IDWA. We performed a random effects meta-analysis of proportions and assessed statistical heterogeneity using the I2 statistic. RESULTS A total of 1923 citations were screened and 5 studies (4 retrospective cohorts, 1 prospective cohort) comprising 3329 participants with IDWA were included in the meta-analysis. Overall pooled random-effects estimates for prevalence of GI malignancy in those with IDWA were low (0.38%, 95% CI 0.00%-1.84%, I2 = 87.7%). Older patients (2.58%, 95% CI 0.00%-8.77%); non-screening populations (2.45%, 95% CI 0.16%-6.39%) and men and post-menopausal women (0.90%, 95% CI 0.11%-3.23%) with IDWA were at increased risk of GI malignancy compared to younger patients (0.00%, 95% CI 0.00%-0.21%); screened populations (0.24%, 95% CI 0.00%-1.10%) and pre-menopausal women (0.00%, 95% CI 0.00%-1.05%). CONCLUSION Overall, IDWA is associated with a low risk of GI malignancy. Older patients and non-screening populations are at elevated risk and require GI investigations. Those not in these subgroups have a lower risk of GI malignancy and may wish to be monitored following discussion of the risk and potential benefits of GI investigations.

Abstract
OBJECTIVES To describe all iron deficiency anaemia (IDA)-related causes during follow-up of patients newly diagnosed with IDA and to assess whether a delayed colorectal cancer (CRC) diagnosis influences survival. DESIGN AND SETTING Retrospective cohort study of patients from general practices in the Dordrecht area, the Netherlands. PARTICIPANTS Men and women aged ≥50 years with a new diagnosis of IDA (ie, no anaemia 2 years previously). METHOD From February 2007 to February 2018, all relevant data were collected from the files of the referral hospital. Early IDA-related cause was defined as established within 18 weeks after IDA diagnosis. Cox proportional-hazards regression was used to analyse survival of patients with CRC diagnosis. RESULTS 587 patients with IDA were included with a median follow-up of 4.6 years. Early and late IDA-related causes could be established in 32% and 8% of patients, respectively. Early and late CRC was found in 8% and 2% of patients, respectively, and were located mainly right sided. After adjustment for age, gender and TNM classification, mortality risk was lower in patients with IDA with early CRC diagnosis, but not significantly (HR 0.30, 95% CI 0.09 to 1.02). CONCLUSION Even with extended follow-up, the cause of IDA remains elusive in the majority of patients with IDA in general practice. However, patients with IDA are at increased risk for in particular right-sided CRC and a late diagnosis of CRC appears to have a detrimental effect on survival in patients with IDA.

Abstract
Iron deficiency anaemia (IDA) is the most common cause of anaemia and a frequent indication for colonoscopy, although the prevalence of colorectal cancer (CRC) in IDA is low. Measurement of faecal haemoglobin by immunochemical techniques (FIT) is used to detect symptomatic patients. We studied FIT in patients with anaemia attending a gastroenterology clinic in Plymouth and looked at an artificial intelligence (AI) learning algorithm (ColonFlag™) in these patients, together with a cohort who had undergone colonoscopy for IDA in London. Of 592 patients referred on the basis of haemoglobin concentration, 21 (3.5%) had CRC. Using ColonFlag™, rather than haemoglobin concentration, in combination with symptoms, would have resulted in prioritisation of 304 patients for urgent referral rather than 592. One CRC would have been missed but might have been detected by FIT, which was not available in this case. In patients aged <55 years in whom the incidence of CRC is low, 15 rather than 109 patients would have been prioritised for urgent referral with no cancers missed. FIT has a high negative predictive value in IDA so its use may enable some patients to avoid investigation and AI learning may be a more useful trigger than haemoglobin concentration for urgent referral for colonoscopy.

Abstract
BACKGROUND/AIMS There has been no evidence for the necessity of endoscopy in asymptomatic young men with iron deficiency anemia (IDA). To determine whether endoscopy should be recommended in asymptomatic young men with IDA, we compared the prevalence of gastrointestinal (GI) lesions between young men (< 50 years) with IDA and those without IDA. METHODS We conducted a case-control study on asymptomatic young men aged < 50 years who underwent both esophagogastroduodenoscopy (EGD) and colonoscopy as part of a health checkup between 2010 and 2014. RESULTS Of 77,864 participants, 128 (0.16%) had IDA and 512 subjects without IDA were matched for several variables including age. Young men with IDA had a significantly higher proportion of colorectal cancer (CRC) (0.8% vs. 0.0%, p = 0.045), villous adenoma (0.8% vs. 0.0%, p = 0.045), and inflammatory bowel disease (IBD; 2.3% vs. 0.4%, p = 0.025) than those without IDA. Additionally, the prevalence of advanced colorectal neoplasia (ACRN) tended to be higher in subjects with IDA than in those without IDA (3.1% vs. 1.0%, p = 0.084). The prevalence of significant lower GI lesions including ACRN and IBD was higher in subjects with IDA than in those without IDA (5.5% vs. 1.4%, p = 0.011). Regarding upper GI lesions, a positive association with IDA was observed only for gastric ulcer (4.7% vs. 1.0%, p = 0.011). CONCLUSION GI lesions including CRC, villous adenoma, IBD, and gastric ulcer were more common in asymptomatic young men with IDA. Our results suggest that EGD and particularly colonoscopy should be recommended even in asymptomatic young men with IDA.

Abstract
Iron Deficiency Anemia (IDA) is a universal health problem and a risk factor for the development of cancer. IDA changes the microenvironment of the human body by affecting both the biological and immunological systems. It increases DNA damage and genomic instability by different mechanisms. IDA is one of the leading causes of the imbalance between different antioxidant enzymes as well as enzymes involved in DNA damage and DNA repair systems of the body. It can affect the biogenesis/expression of microRNAs. IDA interrupts the oxidative phosphorylation energy metabolism and intestinal Cytochrome-P450 systems. It also disturbs multicellular signaling pathways involved in cell survival and helps in tumor angiogenesis. Moreover, IDA is also responsible for the functional deterioration of innate and adaptive immune systems that lead to immunological dysfunctions against invading pathogens. Genomic instability and immunological dysfunctions are the hallmarks of cancer development. In this review, we will review the evidence linking IDA to increased cancer risk.

Total iron-binding capacity is a novel prognostic marker after curative gastrectomy for gastric cancer. Int J Clin Oncol 2018; 23:671-680.

Abstract
BACKGROUND Patients with gastric cancer (GC) are affected by changes in iron status. Before surgery, GC patients are likely to have iron-deficiency anemia; and after gastrectomy, patients suffer from low nutritional status and low iron. This study investigated preoperative iron status associated with prognosis after curative gastrectomy for gastric cancer. METHODS We evaluated preoperative serum hemoglobin (Hgb), Fe and total iron-binding capacity (TIBC) in 298 patients who underwent curative gastrectomy for GC without preoperative chemotherapy, and analyzed these factors' associations with prognosis after surgery. RESULTS Of the 298 patients, 129 (43.2%) had low Hgb levels, and 33 (11.1%) had low TIBC (< 260 µg/dl) that was not associated with Hgb or Fe level. Patients with low TIBC were significantly associated with older age (≥ 65 years old; P = 0.0085), low albumin (< 3.9 g/dl; P = 0.0388) and high CRP (≥ 0.15 mg/dl; P = 0.0018) in multivariate analysis. Low Fe (< 60 µg/dl) was not associated with disease-free survival (DFS) or overall survival (OS); however, low Fe was associated with longer cancer-specific survival in Stage III GC patients (P = 0.0333). Both low Hgb and low TIBC were significantly associated with shorter DFS (Hgb: P = 0.0433; TIBC: P < 0.0001) and shorter OS (Hgb: P = 0.0352; TIBC: P < 0.0001). Low TIBC were significantly associated with shorter DFS (HR 2.167, 95% CI 1.231-3.639, P = 0.0086) and shorter OS (HR 2.065, 95% CI 1.144-3.570, P = 0.0173) in multivariate Cox hazard regression analysis. CONCLUSIONS Preoperative serum TIBC level of GC patients who undergo curative gastrectomy is a novel prognostic marker in univariate and multivariate analyses.

Abstract
About 10% of oesophagogastroduodenoscopies (OGDs) and colonoscopies are done for investigation of iron deficiency anemia (IDA) . Much of the existing guidance on investigation of IDA predates CRC screening, which has driven significant improvements in colonoscopy quality and completion rates, as well as a reduction in Helicobacter pylori prevalence and increase in PPI usage, and therefore probably needs re-consideration. New investigations, e.g. CT colonography, enteroscopy and capsule endoscopy have also been introduced. Areas covered: This review updates the approach to practical investigation of IDA. Medline was searched using the terms iron deficiency AND anemia AND/OR gastroscopy, colonoscopy, capsule and enteroscopy, together with review of recent relevant published abstracts on the topic. Expert commentary: Gastrointestinal pathology is now a more common cause of IDA than upper GI causes, reflecting better colonoscopy accuracy and completion rates as well as changing disease patterns, and carcinomas are more likely cause IDA than benign adenomas. Increasing use of antiplatelet and anticoagulants is driving greater presentation of IDA. Capsule endoscopy, enteroscopy and CT colonography are increasingly used. Fecal occult blood testing may be a useful simple screening method in the frail, as a negative test can avoid the need for invasive tests.

Abstract
Background Establishing the underlying cause of anaemia in general practice is a diagnostic challenge. Currently, general practitioners individually determine which laboratory tests to request (routine work-up) in order to diagnose the underlying cause. However, an extensive work-up (consisting of 14 tests) increases the proportion of patients correctly diagnosed. This study investigates the cost-effectiveness of this extensive work-up. Methods A decision-analytic model was developed, incorporating all societal costs from the moment a patient presents to a general practitioner with symptoms suggestive of anaemia (aged ≥ 50 years), until the patient was (correctly) diagnosed and treated in primary care, or referred to (and diagnosed in) secondary care. Model inputs were derived from an online survey among general practitioners, expert estimates and published data. The primary outcome measure was expressed as incremental cost per additional patient diagnosed with the correct underlying cause of anaemia in either work-up. Results The probability of general practitioners diagnosing the correct underlying cause increased from 49.6% (95% CI: 44.8% to 54.5%) in the routine work-up to 56.0% (95% CI: 51.2% to 60.8%) in the extensive work-up (i.e. +6.4% [95% CI: -0.6% to 13.1%]). Costs are expected to increase slightly from €842/patient (95% CI: €704 to €994) to €845/patient (95% CI: €711 to €994), i.e. +€3/patient (95% CI: €-35 to €40) in the extensive work-up, indicating incremental costs of €43 per additional patient correctly diagnosed. Conclusions The extensive laboratory work-up is more effective for diagnosing the underlying cause of anaemia by general practitioners, at a minimal increase in costs. As accompanying benefits in terms of quality of life and reduced productivity losses could not be captured in this analysis, the extensive work-up is likely cost-effective.

Abstract
The present study aimed to clarify the staging and curative resectability of gastrointestinal cancer found through iron deficiency anemia (IDA). An electronic database was used and females >51 and males >18 years old were identified who had been diagnosed with IDA at the internal medicine outpatient clinic of Asahi General Hospital (Chiba, Japan) from 1 April 2010 to 31 March 2012. IDA was defined as a hemoglobin level of <135 g/l for males and <120 g/l for females, combined with a serum ferritin level of <33.71 pmol/l. Of the 472 patients who had been diagnosed with IDA, 347 patients underwent either a gastroscopy and/or colonoscopy, including 120 patients who had undergone both gastroscopy and colonoscopy, 197 patients who only underwent gastroscopy, and 30 patients who only underwent colonoscopy. In total, 125/472 patients diagnosed with IDA did not undergo a gastroscopy or a colonoscopy. From the 50 patients who were diagnosed with cancer as a result of the investigation, 24 patients had gastric cancer and 23 patients had colorectal cancer. Of the gastric cancer patients, 6 patients were stage I, 3 patients stage II, 5 patients were stage III and 9 patients were stage IV. In colorectal cancer, 9 patients were stage II, 8 patients were stage III and 4 patients were stage IV. Curative surgery including endoscopic treatment was performed on 14 gastric cancer patients and 17 colorectal cancer patients of stage III or lower. Malignancies were found in 50 patients with IDA, and curative surgery was performed on >50% of the patients.

Clin Gastroenterol Hepatol 2017; 15:682-690. [PMID: 27765728 DOI: 10.1016/j.cgh.2016.10.011] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2016] [Revised: 09/14/2016] [Accepted: 10/01/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Gastrointestinal (GI) bleeding in patients receiving anticoagulation agents can be caused by occult malignancies. We investigated the proportions and features of major GI bleeding (MGIB) events related to occult GI cancers in patients receiving anticoagulation therapy. METHODS We analyzed data from the Randomized Evaluation of Long Term Anticoagulant Therapy study (conducted between December 2005 and March 2009 in 951 clinical centers in 44 countries worldwide), which compared the abilities of dabigatran vs warfarin to prevent stroke and systemic embolism in 18,113 patients with atrial fibrillation. Two blinded gastroenterologists independently reviewed source documents of MGIB events (n = 595) that occurred during the study period. We collected data on MGIB events caused by previously unidentified GI malignancies, and compared characteristics of MGIB events in patients who received dabigatran vs warfarin (primary end point), and in patients with bleeding from cancer, vs patients bleeding from a nonmalignant or unidentified source. RESULTS Of 546 unique MGIB events, 44 (8.1%) were found to be from GI cancers (34 of 398 MGIB events in dabigatran users and 10 of 148 MGIB events in warfarin users; P = .60). Colorectal cancer accounted for 35 of 44 of all cancers identified. There were more colorectal cancer-associated MGIB events in the dabigatran group (30 of 34) than in the warfarin group (5 of 10) (P = .02), but more gastric cancer-associated MGIB events in the warfarin group (5 of 10) than in the dabigatran group (1 of 34) (P = .001). There were no differences in the short-term outcomes of cancer-related MGIB events in the dabigatran vs the warfarin group, but 75% of all cancer-related MGIB events required at least 1 blood transfusion and the mean hospital stay was 10.1 days. Compared with MGIB events from a nonmalignant or unidentified source, MGIB from cancer occurred sooner (343.0 vs 223.1 d; P = .003), but the bleeding was more likely to be chronic (for >7 d) (27.3% vs 63.6%; P < .001). CONCLUSIONS In evaluating data from a study of the effects of anticoagulation therapy, we found approximately 1 of every 12 MGIB events to be related to an occult cancer. Approximately two thirds of cancer-related MGIB presents with chronic bleeding, and morbidity, and resource utilization is high.

Abstract
BACKGROUND Anemia is defined as hemoglobin below the cutoff of normal in studies examining the gastrointestinal (GI) tract in iron-deficiency anemia (IDA). Although the risk of GI cancer (GIC) increases as hemoglobin decreases, guidelines do not usually recommend hemoglobin thresholds for IDA investigation. METHODS To elucidate whether underlying GI disorders explain the different hemoglobin values and clinical outcomes observed initially in IDA patients referred for GI workup, we prospectively investigated the diagnostic yield of a thorough GI examination in consecutive IDA adults with predefined hemoglobin <9g/dL and no extraintestinal bleeding. RESULTS 4552 patients were enrolled over 10 years. 96% of 4038 GI lesions were consistent with occult bleeding disorders and 4% with non-bleeding disorders. Predominant bleeding disorders included upper GI ulcerative/erosive lesions (51%), GIC (15%), and angiodysplasias (12%). Diffuse angiodysplasias (45% of angiodysplasias) and GIC showed the lowest hemoglobin values (6.3 [1.5] and 6.4 [1.3]g/dL, respectively). While the spread (diffuse vs. localized) and number (<3 vs. ≥3) of angiodysplasias correlated with the degree of anemia, hemoglobin values were lower in GIC with vs. without ulcerated/friable lesions (6.0 [1.1] vs. 7.0 [1.2]g/dL, P<0.001). CONCLUSION Not only GIC but also diffuse angiodysplasias caused the most severe anemia in IDA with predefined hemoglobin values <9g/dL.

Abstract
BACKGROUND AND OBJECTIVES Red blood cell (RBC) transfusion may be justified in iron deficiency anaemia (IDA) when an increase in oxygen delivery is needed, as sometimes occurs in subjects with haemoglobin <8·0 mg/dL, serious comorbidities or at risk of cardiovascular instability. Earlier investigations showed that some patients with severe IDA requiring transfusion had lower than expected post-transfusion haemoglobin levels with poorer clinical outcomes than other patients. After hypothesizing that haemoglobin responses to transfusion were different and that the underlying gastrointestinal (GI) disorders causing IDA could be a confounder explaining this association, these responses were analysed in a prospective cohort of IDA adults referred for outpatient GI investigation. MATERIALS AND METHODS Transfused patients with proven IDA, baseline haemoglobin at referral <9·0 g/dL and no extraintestinal bleeding were eligible. To assess a homogeneous population, only GI disorders known to cause occult bleeding were considered. Haemoglobin increments per 100 mL of RBCs were investigated. RESULTS In total, 2818 patients were enrolled over 10·5 years. On multivariable regression, diffuse angiodysplasias and GI cancer independently predicted for reduced increments in post-transfusion haemoglobin [adjusted regression coefficients: -0·082 (95% confidence interval, -0·093 to -0·072) and -0·073 (95% confidence interval, -0·081 to -0·066), respectively, P < 0·001 in both]. Haemoglobin responses in the remaining bleeding disorders were adequate and agreed with the principle that one RBC unit increases the haemoglobin an average of 1 g/dL. CONCLUSION The potential differential impact of GI disorders on changes in haemoglobin levels after RBC transfusion could be useful for transfusing physicians, especially for diagnostic purposes.

Abstract
Gastric cancer has high incidence and fatality rates, making chemoprevention agents necessary. There is an ongoing debate about aspirin/nonsteroidal anti-inflammatory drugs (NSAIDs) use can significant reduce the risk of GC. We conducted a meta-analysis of existing studies evaluating the association of anti-inflammatory drug and GC. We performed a systematic literature search of PubMed, Web of Science, Embase, OVID, Cochrane Library and Clincialtrials.gov up to August 31, 2015. Either a fixed-effects or a random-effects model using was based on the result of homogeneity analysis. Subgroup, sensitivity, meta-regression, and publication bias analyses were evaluated. Forty-seven studies were finally included in this meta-analysis. The overall GC risk reduction benefit associated with anti-inflammatory drug use represented an RR of 0.78 (95% CI 0.71 to 0.85) and an adjusted RR of 0.74 (95% CI 0.71 to 0.77). Besides, the prevention benefit of aspirin/NSAIDs ingestion appeared to be confined to those patients with regiment of short or middle-term (≤5 years), high-frequency (>30 times per month) and low dose (<200 mg per day). Further, our data also suggest that COX-2 inhibitors use is a more effective approach in GC prevention (RR, 0.45; 95% CI, 0.29-0.70). In this meta-analysis, our finding support short or middle-term (≤5 years), high-frequency (>30 times per month) and low dose (<200 mg per day) aspirin/NSAIDs intake is a well method for GC prevention and also confirm the inverse association between aspirin/NSAIDs use and GC risk. Additionally, selective COX-2 inhibitors use probably a more effective approach to reduce GC risk.

Abstract
Anemia is a prevalent disease with multiple possible etiologies and resultant complications. Iron deficiency anemia is a common cause of anemia and is typically due to insufficient intake, poor absorption, or overt or occult blood loss. Distinguishing iron deficiency from other causes of anemia is integral to initiating the appropriate treatment. In addition, identifying the underlying cause of iron deficiency is also necessary to help guide management of these patients. We review the key components to an evidence-based, cost-conscious evaluation of suspected iron deficiency anemia.

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
Iron deficiency anemia is the most common type of anemia and can cause asthenia, cognitive and functional impairment, and decompensation of underlying diseases. Iron deficiency anemia is not a disease but is the result of a potentially serious medical problem. Consequently, patients should always undergo investigation of the underlying cause. In men and postmenopausal women, the condition is caused by gastrointestinal loss and malabsorption of iron. In this group, recommended procedures are gastroscopy, colonoscopy and serological testing for celiac disease. If the results of these tests are negative, repeat examinations and iron therapy should be considered. In treatment-refractory or recurrent anemia, the small intestine should be investigated. In this case, the procedure of choice is capsule endoscopy. Iron deficiency anemia should always be treated until iron deposits have returned to normal levels. A wide variety of preparations are available, in both oral and parental formulations.

Abstract
OBJECTIVE Ten percent of adults presenting with iron deficiency anaemia (IDA) have underlying cancer. This analysis - the Iron Deficiency as an Indicator Of Malignancy (IDIOM) study - was undertaken to assess whether five simple clinical parameters can usefully predict the likelihood of gastrointestinal (GI) malignancy on subsequent investigation of patients with IDA. DESIGN Retrospective observational study, with multivariable analysis of the predictive value of sex, age, haemoglobin concentration (Hb), mean red cell volume (MCV) and iron studies for the risk of underlying GI malignancy. SETTING District General Hospital IDA clinic. PATIENTS 720 adults with confirmed IDA. RESULTS Sex, age and Hb were strongly associated with the risk of GI malignancy-the parsimonious model including only these variables yielded ORs of 4.0 (95% CI 2.3 to 7.0) for males compared with females; 3.3 (95% CI 1.7 to 6.4) for age >70 years compared with ≤70 years; and 5.3 (95% CI 2.4 to 11.7) for a Hb of ≤91.4 g/L compared with ≥111.5 g/L. Combining these risk factors identified a subgroup (12% of the study population) at particularly low risk (<2% likelihood), and a second subgroup (16% of the study population) at especially high risk (>20% likelihood) of underlying GI malignancy. CONCLUSIONS Three simple and objective clinical parameters can be combined to provide a clinically useful cancer risk stratification model for subjects with IDA. This may assist with patient counselling and the prioritisation of investigational resources.

Abstract
INTRODUCTION Small bowel capsule endoscopy (SBCE) is a useful diagnostic modality in small bowel disorders. Iron deficiency anaemia (IDA) is one of the most common indications for SBCE. However, there are limited data on the diagnostic yield for IDA alone, and little is known about the clinical impact and long-term outcome of patients following SBCE. AIM To determine the diagnostic yield of SBCE in IDA and to examine outcome. MATERIALS AND METHODS A retrospective review of a tertiary referral centre's database over a 21-month time period was carried out. Information on follow-up and management was obtained through chart review. RESULTS In all, 309 SBCEs were identified, 30% (n=93) for anaemia and in 70% (n=65), follow-up data were available. The small bowel diagnostic yield for IDA was 53% (n=35), including angiodysplasia 49% (n=17), nonspecific inflammation 34% (n=12), active bleeding 11% (n=4) and Crohn's disease 6% (n=2). In addition, 16% (n=10) had abnormalities (gastritis, gastric antral vascular ectasia, duodenitis) outside the small bowel. In all, 42% (n=27) were persistently anaemic after a mean follow-up of 9.3 months. Of these, 52% (n=14) and 48% (n=13) had positive and negative SBCEs, respectively. In total, SBCE led to a change in treatment in 28 patients (44%), of whom 17 (61%) remained anaemic. CONCLUSION This study shows a high overall diagnostic yield for SBCE in IDA 71% (n=45). Despite the majority, 53% (n=24), of patients with positive tests receiving specific treatment, 61% (n=17) remained anaemic in the long term. SBCE results were not predictive of long-term outcome even when stratified for a change in management.

Abstract
BACKGROUND Iron-deficiency anemia (IDA) is the most common cause of anemia worldwide. Current guidelines recommend the use of small-bowel capsule endoscopy (SBCE) in IDA. Evidence of the validity of SBCE in patients with IDA alone is still limited. OBJECTIVE To assess the diagnostic yield (DY) of SBCE in IDA by pooling data from relevant studies. DESIGN Systematic review and meta-analysis. Fixed-effects or random-effects models were used as appropriate. SETTING Studies that estimated the DY of SCBE in IDA were identified. Two investigators independently conducted the search and data extraction. PATIENTS A total of 24 studies enrolling 1960 patients with IDA who underwent SBCE were included. MAIN OUTCOME MEASUREMENTS Per-patient DY, with 95% confidence intervals. Subgroup analysis was also performed. RESULTS The pooled DY of SBCE in IDA, evaluated by a random-effects model, was 47% (95% CI, 42%-52%), but there was statistically significant heterogeneity among the included studies (inconsistency index [I(2)] = 78.8%, P < .0001). The pooled DY of SBCE in studies focused solely on patients with IDA (subset 1, 4 studies) was 66.6% (95% CI, 61.0%-72.3%; I(2) = 44.3%); conversely, that of studies not focusing only on IDA patients (subset 2, 20 studies) was 44% (95% CI, 39%-48%; I(2) = 64.9%). In particular, more vascular (31% vs 22.6%, P = .007), inflammatory (17.8% vs 11.3%, P = .009), and mass/tumor (7.95% vs 2.25%, P < .0001) lesions were detected with SBCE in patients participating in the studies in subset 1. LIMITATIONS Heterogeneity of studies, retrospective design, and selection bias. CONCLUSIONS This analysis demonstrates the validity of SBCE in the investigation of patients with IDA and negative findings on a previous diagnostic workup, although certain factors such as heterogeneity and quality of the included studies should be taken into account.

Abstract
BACKGROUND & AIM The role of Small-Bowel Capsule Endoscopy (SBCE) in Iron Deficiency Anemia (IDA) alone is still under validation. We aim to assess the usefulness of SBCE in patients with IDA alone. METHODS Retrospective study; patients with IDA (no GI symptoms or known previous diagnosis), who underwent SBCE were included. SBCE findings were classified as clinically significant/sinister (small-bowel malignancy, significant/sinister inflammation and/or strictures and coeliac disease) or vascular, i.e., signifcant/angioectasias (P1/P2 lesions). RESULTS A total of 221 (151F/70M) patients had SBCE for IDA as the sole indication. The diagnostic yield (DY) was 30.7% (68/221). The DY for significant/sinister pathology and significant/angioectasias was 9% and 21.7%, respectively. In those ≤ 40 years (20; 13F/7M), significant pathology was found in 25% (5/20); in the >40-year group (201; 138F/63M), significant/sinister pathology was found in 7.5% (15/201), p = 0.0231. None of the patients ≤40 years had angioectasias, such lesions were found in 48/201 (21.7%) of those >40 years, p = 0.009. Fifty percent of those >80 years (16; 12F/4M) had angioectasias, but none had significant/sinister pathology (p = 0.0126). On multiple regression analysis, only prior blood transfusion was predictive of higher DY in SBCE. CONCLUSIONS IDA alone is one of the main indications (27%) for referral to SBCE; the majority of patients are >40 years. In our cohort, the DY of SBCE for IDA was 30.7% and the commonest finding was angioectasias. The detection rate of sinister small-bowel pathology for those >40 years is low decreasing to zero in the >80 age group. In contrast, 25% of those ≤40 years had a sinister diagnosis.

Abstract
Iron deficiency anaemia (IDA) is the most common form of anaemia worldwide. In men and postmenopausal women the commonest cause of IDA is blood loss from lesions in the gastrointestinal tract, making it a common cause of referral to gastroenterologists. Causes of IDA relate either to blood loss or iron malabsorption. After confirmation with laboratory tests, gastrointestinal evaluation is almost always indicated to exclude gastrointestinal malignancy. Specific patient groups such as premenopausal women, patients with low-normal ferritin and iron-deficient patients without anaemia may need an individualized approach. A small proportion of patients have recurrent or persistent IDA despite negative standard endoscopies. These patients with obscure gastrointestinal bleeding usually require evaluation of the small bowel with capsule endoscopy or double balloon enteroscopy. Treatment should involve prompt iron replacement plus diagnostic steps directed towards correcting the underlying cause of IDA. Oral iron replacement is cheap and effective, but parenteral (intravenous) therapy may be required due to intolerance, noncompliance or treatment failure with oral therapy.

Abstract
BACKGROUND Both upper and lower endoscopies are indicated in patients with iron deficiency anaemia. However, these examinations are negative in a high proportion of cases. AIMS To assess whether faecal-immunochemical test (FIT) may be useful in selecting patients at higher risk of bleeding lesions in iron deficiency anaemia patients. METHODS Iron deficiency anaemia patients without overt bleeding were prospectively enrolled. All patients performed FIT, and underwent both upper and lower endoscopy. Predictive factors of potential bleeding lesions were evaluated at multivariate analysis. RESULTS FIT was positive in 48 (34.3%) out of 140 enrolled patients, and a potential bleeding lesion was present in 63 (45%) patients. An endoscopic lesion was detected more frequently in FIT-positive than -negative patients (79.2% vs 27.2%; p<0.0001), at both upper endoscopy (52.1% vs 18.5%; p=0.0002) and colonoscopy (33.3% vs 8.7%; p=0.001). At multivariate analysis, FIT was found to be an independent predictor of both bleeding lesions (OR=9.5; 95% CI: 4.1-22; p<0.001) and cancer (OR=4.0, CI: 1.1-15; p=0.029). CONCLUSIONS FIT positive-iron deficiency anaemia patients without overt bleeding are at increased risk to present with a bleeding lesion at endoscopy, including cancer. FIT positivity in this setting could be useful to prioritize urgent endoscopy.

Abstract
A substantial volume of the consultations requested of gastroenterologists are directed towards the evaluation of anemia. Since iron deficiency anemia often arises from bleeding gastrointestinal lesions, many of which are malignant, establishment of a firm diagnosis usually obligates an endoscopic evaluation. Although the laboratory tests used to make the diagnosis have not changed in many decades, their interpretation has, and this is possibly due to the availability of extensive testing in key populations. We provide data supporting the use of the serum ferritin as the sole useful measure of iron stores, setting the lower limit at 100 microg/l for some populations in order to increase the sensitivity of the test. Trends of the commonly obtained red cell indices, mean corpuscular volume, and the red cell distribution width can provide valuable diagnostic information. Once the diagnosis is established, upper and lower gastrointestinal endoscopy is usually indicated. Nevertheless, in many cases a gastrointestinal source is not found after routine evaluation. Additional studies, including repeat upper and lower endoscopy and often investigation of the small intestine may thus be required. Although oral iron is inexpensive and usually effective, there are many gastrointestinal conditions that warrant treatment of iron deficiency with intravenous iron.

Abstract
GOAL To review the literature on the significance, risk factors, and management of occult and gross gastrointestinal (GI) bleeding in patients on antiplatelets and/or anticoagulants. STUDY Relevant original and review articles and their bibliographies were analyzed. Estimates of risks and therapeutic outcomes were obtained from randomized trials, whereas risk factor identification was gathered from cross-control and prospective cohort studies. RESULTS Antiplatelets and anticoagulants do not diminish the positive predictive value of fecal occult blood testing to find GI pathology. They increase the risk of gross GI bleeding, and predictors of hemorrhage include history of GI bleeding or ulcer disease, higher intensity of anticoagulation, combination therapy, and presence of comorbid conditions. A bleeding site is identified in most patients with peptic ulcer being the most common. In case of significant bleeding, complete or partial reversal of anticoagulation is undertaken on the basis of the balance of risks between bleeding and thromboembolic events. Early endoscopy can reveal lesions requiring endoscopic hemostasis, which can be performed in the setting of low-intensity anticoagulation. In patients with history of peptic disease or bleeding from an acid-related lesion, proton-pump inhibitors and Helicobacter pylori eradication reduce the risk of upper GI bleeding even when antiplatelet therapy is continued. CONCLUSIONS Predictors of bleeding on antiplatelets and/or antithrombotics therapy have been identified, but formulation and validation of a GI bleeding index for stratification of risk in individual patients is suggested. Reversal of anticoagulation in bleeding patients is associated with a low risk of thromboembolic events and permits the performance of diagnostic and therapeutic endoscopy. Proton-pump inhibitors and H. pylori eradication reduce the risk of rebleeding in those with acid-related disease.

Abstract
OBJECTIVE The study aim is to determine the relationship between the prevalence of colorectal cancer and iron status in elderly anemic and non-anemic patients. METHODS We retrospectively investigated 359 consecutive elderly patients, aged 70 years and more, who presented to a geriatric department and who underwent a total colonoscopy. The histopathologic diagnosis of colorectal carcinoma was the primary outcome measure, and its presence was compared with the iron status, evaluated by serum ferritin and hemoglobin levels. RESULTS Less than half of the patients with colorectal carcinoma had iron-deficiency anemia. The prevalence of colorectal carcinoma was similar among patients with a serum ferritin level less than 50 microg/L (16%), between 50 and 100 mirog/L (20%), and greater than 100 microg/L (13%), and was not different between anemic and non-anemic patients. Sex (odds ratio for men 2.1; 95% confidence interval [CI], 1.2-3.9) and increasing age (6.6% per year; 95% CI, 1.2-12.4), but not hemoglobin and serum ferritin, were independent risk factors for colorectal carcinoma. Those with a proximal colorectal carcinoma had a lower hemoglobin and ferritin level and a higher prevalence of iron-deficiency anemia compared with patients with a distal colorectal carcinoma. CONCLUSION The prevalence of colorectal carcinoma is high in anemic and non-anemic elderly symptomatic patients, irrespective of the iron status. Therefore, the decision to order a colonoscopy in older patients should not only be considered in patients with anemia or iron deficiency but also in patients with suspicious symptoms without anemia or iron deficiency.

Abstract
BACKGROUND Iron deficiency anaemia (IDA) due to occult gastrointestinal (GI) blood loss usually remains unnoticed until patient become symptomatic. There is sparse data in IDA patients without gastrointestinal symptoms. This study was designed to find out the frequency and predictors of endoscopic lesions in IDA without gastrointestinal symptoms. Cross-sectional study performed on a convenience sample of consecutive subjects. METHODS Ninety five consecutive patients with laboratory based diagnosis of IDA having no gastrointestinal symptoms were interviewed and their clinical and biochemical variables were recorded. All the study patients underwent esophago-gastroduodenoscopy (EGD) and colonoscopy. Endoscopic findings were documented as presence/absence of bleeding related lesion and presence/absence of cause of IDA. Multiple logistic regressions were performed to identify variables significantly related to outcome variables. RESULTS Possible cause of anaemia was found in 71% and bleeding related lesions were found in 53% of patients. Upper gastrointestinal tract lesions were found in 41% of patients with bleeding related lesions. On multivariable logistic regression; advancing age, low mean corpuscular volume (MCV

Abstract
Although anaemia is recognised as a feature of colorectal cancer, the precise risk is unknown. We performed a case–control study using electronic primary care records from the Health Improvement Network database, UK. A total of 6442 patients had a diagnosis of colorectal cancer, and were matched to 45 066 controls on age, sex, and practice. We calculated likelihood ratios and positive predictive values for colorectal cancer in both sexes across 1 g dl−1 haemoglobin and 10-year age bands, and examined the features of iron deficiency.In men, 178 (5.2%) of 3421 cases and 47 (0.2%) of 23 928 controls had a haemoglobin <9.0 g dl−1, giving a likelihood ratio (95% confidence interval) of 27 (19, 36). In women, the corresponding figures were 227 (7.5%) of 3021 cases and 58 (0.3%) of 21 138 controls, a likelihood ratio of 41 (30, 61). Positive predictive values increased with age and for each 1 g dl−1 reduction in haemoglobin. The risk of cancer for current referral guidance was quantified. For men over 60 years with a haemoglobin <11 g dl−1 and features of iron deficiency, the positive predictive value was 13.3% (9.7, 18) and for women with a haemoglobin <10 g dl−1 and iron deficiency, the positive predictive value was 7.7% (5.7, 11). Current guidance for urgent investigation of anaemia misses some patients with a moderate risk of cancer, particularly men.
