Abstract
Abstract
Anemia is a common finding in the elderly. Approximately 10 percent of the elderly suffers from anemia. Anemia per se is an independent factor of mortality in older patients regardless its cause. Frailty is also frequent in geriatric patients. That means that there is a decreased reserve capacity to react to different stress factors including anemia. The frequent presence of heart failure and also impaired cerebrovascular circulation makes more difficult to tolerate anemia in older age.
Anemia is a symptom, finding and treating the underlying cause is also important.
Treatment always depends on clinical findings: the more severe the symptoms, the more important to treat them. Severity of anemia depends not only the underlying cause, degree of anemia, co-morbidities and frailty of the patients, but also the speed of its development. Sudden blood loss due to an accident is less well tolerated than the same degree of anemia due to B12 deficiency.
Main causes of anemia in the elderly include nutritional deficiencies, chronic diseases, tumors, and certain hematological malignancies such as chronic lymphocytic leukemia, multiple myeloma, myelodysplastic syndrome.

Abstract
Iron is an essential micronutrient for a myriad of physiological processes in the body beyond erythropoiesis. Iron deficiency (ID) is a common comorbidity in patients with heart failure (HF), with a prevalence reaching up to 59% even in non-anaemic patients. ID impairs exercise capacity, reduces the quality of life, increases hospitalisation rate and mortality risk regardless of anaemia. Intravenously correcting ID has emerged as a promising treatment in HF as it has been shown to alleviate symptoms, improve quality of life and exercise capacity and reduce hospitalisations. However, the pathophysiology of ID in HF remains poorly characterised. Recognition of ID in HF triggered more research with the aim to explain how correcting ID improves HF status as well as the underlying causes of ID in the first place. In the past few years, significant progress has been made in understanding iron homeostasis by characterising the role of the iron-regulating hormone hepcidin, the effects of ID on skeletal and cardiac myocytes, kidneys and the immune system. In this review, we summarise the current knowledge and recent advances in the pathophysiology of ID in heart failure, the deleterious systemic and cellular consequences of ID.

Abstract
Aim Investigating the prevalence of hospital-acquired anaemia in a United Kingdom (UK) secondary care setting to describe the level of appropriate management prior to discharge back to primary care. Design and settings An observational study of 13 medical and surgical wards in a UK district general hospital. Method Single-day examination of notes, blood results and drug charts, with a 30-day follow up, using pre-set definitions of anaemia and exclusion criteria. Results Two hundred and sixty-seven patients were included. Of them, 52% were anaemic on admission, 62.2% were anaemic on the study day, 16% had hospital-acquired anaemia and 49%-82% had no biochemical indices checked during the admission or in the last 12 months. Also, 53% of anaemic patients are being discharged without appropriate treatment, with over a third being under-investigated. Conclusion The prevalence of anaemia in a UK district general hospital is high. Causes of anaemia are complex, posing a potentially modifiable risk factor for falls, readmission and mortality.

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.

[PMID: 30415506 PMCID: PMC6351899 DOI: 10.1002/ehf2.12379] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Revised: 07/22/2018] [Accepted: 10/10/2018] [Indexed: 12/15/2022] Open
Abstract
Aims Anaemia and iron deficiency (ferritin level < 100 or 100–300 μg/L with transferrin saturation < 20%) are prevalent in heart failure. Mechanistically, iron deficiency is linked to poor intestinal uptake, increased intestinal loss, and chronic inflammation. However, the prevalence of underlying gastrointestinal malignancies is not established in iron‐deficient heart failure with or without anaemia. Methods and results Patients followed up in a single‐centre, heart failure database with baseline registration of haemoglobin and iron status were retrospectively evaluated. The proportion of patients undergoing upper and lower gastrointestinal endoscopy between inclusion and censoring was determined. Afterwards, the prevalence of biopsy that confirmed intestinal malignancies in relation to baseline iron and haemoglobin status was determined. Anaemia was defined as a haemoglobin level <12 g/dL, and iron deficiency according to the aforementioned criteria. Of the 1197 patients in the database, 699 (59%) patients underwent full endoscopic workup over a mean follow‐up of 50 ± 27 months. A total of 50 intestinal malignancies were identified (n = 42, 84%, in iron‐deficient vs. n = 8, 16%, non‐iron‐deficient patients; P < 0.001). The prevalence of intestinal malignancies was non‐statistically different in iron‐deficient patients with anaemia (n = 12/129, 9.3%) or without anaemia (n = 30/287, 10.5%; P = 0.551). The prevalence was much lower in patients without iron deficiency with anaemia (n = 5/83, 6%) or without anaemia (n = 3/200, 1.5%). In patients with iron deficiency but without anaemia (a group in which the role of endoscopic workup is less established), ferritin levels carried an inverse diagnostic capacity in detecting patients with an underlying malignancy (area under the curve = 0.741, P < 0.001). A ferritin level < 56 μg/L had the best acuity, detecting malignancies with a sensitivity of 80% and a specificity of 71%. Conclusions Endoscopic evaluation is warranted in heart failure patients with iron‐deficient anaemia given the high prevalence of underlying intestinal malignancies, as advised by gastroenterology guidelines. However, additional research is needed assessing the best approach to patients with iron deficiency without anaemia, given the high occurrence of intestinal malignancies in these patients. A lower ferritin level could potentially help stratify the need for an endoscopic workup in these patients.

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
Anemia in older adults is a risk factor for numerous negative outcomes. There is no standard definition, but in most studies, anemia is defined as a hemoglobin value <12 g/dL for women and <13 g/dL for men. Absolute iron deficiency anemia is defined as the combination of anemia and the absence of total body iron. Serum ferritin is the most frequently used diagnostic parameter, but its concentration increases with age and in the presence of inflammatory diseases. Other laboratory tests, such as transferrin saturation, soluble transferrin receptor and the soluble transferrin receptor/ferritin index might provide useful information, but there is a wide variety in the cut-off values and interpretation of the results. Recent research regarding hepcidin as a central regulator of iron homeostasis is promising, but it has not been used yet for the routine diagnosis of iron deficiency anemia. In older iron deficiency anemia patients, an esophagogastroduodenoscopy and colonoscopy should be initiated in order to identify the underlying bleeding cause. CT colonography can replace a colonoscopy, and in specific cases, a video capsule is recommended. It remains crucial to keep in mind which potential benefits might be expected from these investigations in this vulnerable population, taking into account the comorbidity and life expectancy, and one should discuss in advance the possible therapeutic options and complications with the patient, a family member or a proxy. Oral iron administration is the standard treatment, but parenteral iron is a convenient and safe way to provide the total iron dose in one or a few sessions. Geriatr Gerontol Int 2018; 18: 373-379.

The evaluation of anaemia in an older primary care population: retrospective population-based study. BJGP Open 2017; 1:bjgpopen17X101157.

Abstract
Background Anaemia is common in older people and the identification of potentially reversible haematinic deficiencies relies on appropriate investigation, often undertaken in primary care. Aim To determine the laboratory prevalence of anaemia, the types of anaemia observed, and the biochemical and haematological investigations undertaken to characterise any associated haematinic abnormality in older primary care patients. Design & setting A retrospective primary care based study of patients aged >65 years undergoing a full blood count in Oxfordshire, UK between 1 January 2012 and 31 December 2013. Method Consecutive patients aged >65 years with a full blood count were identified retrospectively from a laboratory database. Patient demographics, number of blood tests and additional laboratory investigations requested were recorded. World Health Organisation (WHO) criteria were used to define anaemia. Results In total 151 473 full blood counts from 53 890 participants were included: 29.6% of patients were anaemic. The majority had a normocytic anaemia (82.4%) and 46.0% of participants with anaemia had no additional investigations performed. The mean haemoglobin was lower in the anaemic group that underwent further investigation than those who did not (Hb 10.68 g/dl versus 11.24 g/dl, P<0.05): 33.2 % of patients with a microcytic anaemia (mean cell volume <80) did not have any markers of iron status measured. Conclusion A large proportion of older adults in primary care with a recent blood test are anaemic, the majority with a normocytic anaemia, with evidence of inadequate investigation. Those with lower haemoglobin are more likely to be further investigated. Further work is needed to understand the approach to anaemia in older adults in primary care.

Abstract
OBJECTIVE The need for endoscopic investigation in patients with iron deficiency without anemia (ID) is not established. METHODS Data from patients with ID (serum ferritin ≤20 ng/mL, normal hemoglobin) studied with upper and lower endoscopies were retrospectively analyzed. Patients evaluated for iron deficiency anemia (IDA) served as controls, matched by sex and age in the proportion of 2:1. The groups were compared for the presence, type, location and age distribution of endoscopic findings. RESULTS Altogether 109 patients (55% women; mean age 59.6 ± 13.5 years; aged <50 years [27.5%]; 50-69 years [43.1%]; ≥70 years [29.4%]) were included in the ID group and 218 matched controls in the IDA group. Lesions were found in a similar proportion of patients (53.2% in the ID group vs 49.1% in the IDA group, P = 0.48) irrespective of age (P = 0.92). The colonoscopy diagnostic yield was low in both the ID and IDA subgroups of aged <50 years (6.3% vs 4.2%, P = 0.76). Multivariate analysis revealed a significant relationship between age (odds ratio [OR] 1.04, 95% confidence interval [CI] 1.02-1.06) and male sex (OR 2.28, 95% CI 1.18-4.39) with a positive colonoscopy. Malignancy was significantly less frequent in the ID group (1.8% vs 14.2%, P < 0.05). CONCLUSIONS The prevalence of gastrointestinal lesions in patients with and without anemia was similar but malignancy was eight times less frequent in the ID group. Systematic endoscopic evaluation in patients with ID is therefore questionable.

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/Aims. To evaluate the incidence of gastric adenoma and gastric cancer in colorectal cancer patients, as well as the clinicopathological features that affect their incidence. Methods. Among patients who underwent surgery after being diagnosed with colorectal cancer between January 2004 and December 2013 at Chungnam National University Hospital, 142 patients who underwent follow-up upper gastrointestinal endoscopy were assigned to the patient group. The control group included 426 subjects randomly selected. The patient group was subdivided into two: one that developed gastric adenoma or cancer and one that did not. Clinicopathological characteristics were compared between these groups. Results. In total, 35 (24.6%) colorectal cancer patients developed a gastric adenoma or gastric cancer, which was higher than the number in the control group (20 [4.7%] patients; p < 0.001). Age, alcohol history, and differentiation of colorectal cancer were associated with higher risks of gastric adenoma or gastric cancer, with odds ratios of 1.062, 6.506, and 5.901, respectively. Conclusions. In colorectal cancer patients, screening with upper gastrointestinal endoscopy is important, even if no lesions are noted in the upper gastrointestinal tract at colorectal cancer diagnosis. Endoscopic screening is particularly important with increasing age, history of alcohol consumption, and poor cancer differentiation.

Abstract
BACKGROUND AND AIMS The etiology of iron deficiency (ID) without anemia in young men is unclear, and there are no evidence-based recommendations for the required gastrointestinal (GI) evaluation. The aims of this study were to examine the incidence of significant GI pathology and the development of anemia during the follow-up of young men presenting with ID, but without anemia. METHODS All young men (18-30 years) who served in the Israel Defense Forces during the years 2005-2013 and had at least a single laboratory test indicative of ID without anemia were followed until the diagnosis of significant GI pathology or discharge from military service. RESULTS The study population included 2061 young men (mean age 20.7±1.8). During follow-up of 3150 person years, significant GI pathologies were diagnosed in 39 patients: inflammatory bowel disease in 25 (1.2%), celiac disease in 8 (0.4%), and peptic disease in 4 (0.1%). No cases of GI-related cancer were diagnosed. ID anemia developed during follow-up in 203 (9.8%). Lower baseline hemoglobin levels, lower ferritin levels, and younger age at diagnosis were more common among those who developed anemia. The development of anemia was a predisposing factor for the diagnosis of GI pathology (risk ratio=3.60, 95% confidence interval 1.34-8.32, P=0.012). CONCLUSION Significant GI pathology is very uncommon in young men presenting with ID. Overt anemia developed in close to 10% of the study cohort. Therefore, we advise simple GI evaluation (celiac serology, C-reactive protein or fecal calprotectin, and urease breath test) as well as follow-up in this population.

Abstract
BACKGROUND AND STUDY AIMS Gastric cancer is highly prevalent in Kashmir, as are lower gastrointestinal (LGI) malignancies. Colonic cancer, gastric cancer, and coeliac disease are the most important gastrointestinal (GI) causes of iron deficiency anaemia (IDA) worldwide. Approximately 9% of patients with IDA present with a suspicious lesion in the GI tract upon examination. However, the absence of GI symptoms and a possible lesion accounting for blood loss in IDA have not been studied in this zone with a high prevalence of GI malignancy. We aimed to examine IDA patients without GI symptoms to determine the most plausible cause of their blood loss. PATIENTS AND METHODS A total of 100 patients with IDA and 250 control subjects without IDA and referred for gastrointestinal endoscopy were enrolled in a cross-sectional, comparative study. Patients presenting with a significant lesion proportionate to their anaemia in the upper GI tract were not examined further, if no further strong indications were present. RESULTS Twenty-nine patients (29%) were found to have malignancy: 13 with gastric cancer and 16 with colonic malignancies. Other apparent causes of GI blood loss included peptic ulcer disease in 10 (10%) patients, haemorrhoids in 22 (25%), polyps in eight (three in the upper GI tract and five in the LGI tract), gastric erosions in eight (8%), and angiodysplasia, diverticulitis, and trichuriasis in two (2%) each. CONCLUSION In light of the high incidence of GI malignancies in this patient group, a low threshold for GI screening as well as mass screening for IDA is needed.

Abstract
Anemia is a common diagnosis in the geriatric population, especially in institutionalized and hospitalized elderly. Most common etiologies for anemia in elderly people admitted to a geriatric ward are iron-deficiency anemia and anemia associated with chronic disease. Determination of serum ferritin is the most used assay in the differential diagnosis, despite low sensitivity and moderate specificity. New insights into iron homeostasis lead to new diagnostic assays such as serum hepcidin, serum transferrin receptor and reticulocyte hemoglobin equivalent.Importance of proper diagnosis and treatment for this population is large since there is a correlation between anemia and morbidity - mortality. Anemia is usually defined as hemoglobin less than 12 g/dl for women and less than 13 g/dl for men. There is no consensus for which hemoglobinvalue an investigation into underlying pathology is obligatory. This needs to be evaluated depending on functional condition of the patient.

Abstract
AIM: To determine whether patients hospitalized with gastrointestinal (GI) blood loss anemia are being checked and treated for iron deficiency.
METHODS: Retrospective chart review was conducted for all patients admitted to a single tertiary care hospital between 11/1/2011 and 1/31/2012 for any type of GI bleeding. The primary endpoint was the percentage of patients who had their iron studies checked during a hospitalization for GI blood loss anemia. Secondary outcomes included percentage of anemic GI bleeders who had adequate documentation of anemia and iron deficiency, and those who were treated for their iron deficiency. Then we tried to identify possible predictors of checking iron studies in an attempt to understand the thought process that physicians go through when managing these patients. Iron deficiency was defined as Iron saturation less than 15% or ferritin level less than 45 μg/L. Anemia was defined as hemoglobin level less than 13 g/dL for males and 12 g/dL for females.
RESULTS: Three hundred and seven GI bleeders were hospitalized during the study period, and 282 of those (91.9%) had anemia during their hospital stay. Ninety-five patients (30.9%) had iron studies performed during hospitalization, and 45 of those (47.4%) were actually found to be iron deficient. Only 29 of those 45 iron deficient patients were discharged home on iron supplements. Of the 282 patients that had anemia during hospitalization, 50 (17.7%) had no documentation of the anemia in their hospital chart. Of the 45 patients that had lab proven iron deficiency anemia (IDA), only 22 (48.5%) had documentation of IDA in at least one note in their chart. Predictors of checking iron studies in anemic GI bleeders were lower mean corpuscular volume, documentation of anemia, having fecal occult blood testing, not having hematemesis or past history of GI bleeding. There were no significant differences between the teaching and non-teaching services in any patient characteristics or outcomes.
CONCLUSION: Iron deficiency is under-diagnosed, under-recognized even when iron studies were checked, and under-treated in hospitalized patients with GI bleeding.

Abstract
Anemia in elderly population have a great incidence and is related to increased mortality risk. The incidence of nutrition in anemia is about one third of the total. Caloric and protein restriction, iron, vitamin B12, folic deficiency are the causes of nutritional anemia. Protein and energy malnutrition stimulate an increased cytokines production with induction of inflammation, immunodeficiency and anemia. Anorexia and obesity can be associated with anemia due to increased cytokines and hepdicin serum level. Macrophages activity is inhibited and a decrease in red blood cells (RBC), hemoglobin (Hb) concentration due to ineffective erythropoiesis is observed. An adequate energy and protein diet is necessary to reduce inflammation and increase iron absorption. A minimum of 1700 kcal/day and 1.7 gr/kg/day of protein intake are necessary to maintain anabolism in chronic patients to prevent and treat anemia. Iron supplementation by intravenous injection is safe and effective to correct severe iron deficiency. The supplementation of vitamins and oligomineral are useful to reduce oxidative stress and improve RBC longevity. Anemia in elderly could be prevented by an adequate nutrition, a simple and not expensive intervention, and associated to physical exercise reduce the incidence of mortality rate.

Abstract
INTRODUCTION We receive fast track referrals on the basis of iron deficiency anaemia (IDA) for patients with normocytic anaemia or for patients with no iron studies. This study examined the yield of colorectal cancer (CRC) among fast track patients to ascertain whether awaiting confirmation of IDA is necessary prior to performing bowel investigations. METHODS A review was undertaken of 321 and 930 consecutive fast track referrals from Centre A and Centre B respectively. Contingency tables were analysed using Fisher's exact test. Logistic regression analyses were performed to investigate significant predictors of CRC. RESULTS Overall, 229 patients were included from Centre A and 689 from Centre B. The odds ratio for microcytic anaemia versus normocytic anaemia in the outcome of CRC was 1.3 (95% confidence interval [CI]: 0.5-3.9) for Centre A and 1.6 (95% CI: 0.8-3.3) for Centre B. In a logistic regression analysis (Centre B only), no significant difference in CRC rates was seen between microcytic and normocytic anaemia (adjusted odds ratio: 1.9, 95% CI: 0.9-3.9). There was no statistically significant difference in the yield of CRC between microcytic and normocytic anaemia (p=0.515, Fisher's exact test) in patients with anaemia only and no colorectal symptoms. Finally, CRC cases were seen in both microcytic and normocytic groups with or without low ferritin. CONCLUSIONS There is no significant difference in the yield of CRC between fast track patients with microcytic and normocytic anaemia. This study provides insufficient evidence to support awaiting confirmation of IDA in fast track patients with normocytic anaemia prior to requesting bowel investigations.

Abstract
Anemia is now recognized as a risk factor for a number of adverse outcomes in the elderly, including hospitalization, morbidity, and mortality. What constitutes appropriate evaluation and management for an elderly patient with anemia, and when to initiate a referral to a hematologist, are significant issues. Attempts to identify suggested hemoglobin levels for blood transfusion therapy have been confounded for elderly patients with their co-morbidities. Since no specific recommended hemoglobin threshold has stood the test of time, prudent transfusion practices to maintain hemoglobin thresholds of 9-10 g/dL in the elderly are indicated, unless or until evidence emerges to indicate otherwise.

Abstract
Anemia is not physiologically associated with increasing age but a symptom of an underlying disease. The individual patient's wish, results of geriatric assessment, and therapeutic options regarding life expectancy and quality of life must be taken into consideration when determining the diagnostic steps to be taken. Prevalence of anemia is high, reaching up to 40% among geriatric inpatients. There are various reasons for anemia, but the three most frequent forms of anemia in the elderly are iron deficient anemia (IDA), anemia of chronic diseases (ACD), and unexplained anemia (UA). This article will, therefore, be limited to these forms. Until now no guidelines have been developed concerning diagnostic and therapeutic steps for anemia in the elderly. For basic diagnostics, the analysis of hematologic parameters such as hemoglobin, ferritin, and the saturation of transferrin are recommended. Therapeutic options have to be chosen according to the underlying disease.

Abstract
Anemia is a common concern in older people and can have significant morbidity and mortality. Because anemia is a sign, not a diagnosis, an evaluation is almost always warranted to identify the underlying cause. The purpose of this study was to study the clinical profile of elderly patients with anemia and to study characteristics of hematological types of anemia in such patients as well as the closest possible etiological profile. Hundred patients above the age of 60 years were included in the study. Clinical profile with laboratory studies of Hemoglobin and diagnostic tests to fix the etiology. Majority of patients had normocytic blood picture. Renal failure was the most common underlying chronic disease. Significant number of patients were on non steroidal anti-inflammatory drugs which could contribute to the anaemia. 14% of the patients had an underlying malignancy. 73.3% of the patients in the microcytic group had an underlying GI lesion on endoscopy. Identifying anemia as an important aspect of a comprehensive geriatric assessment is absolutely essential further to clinical detection. Confirming the type of anemia is critical to direct the investigation for profiling the etiology since it is well known that the treatment of anemia goes a long way in improving the overall outcome and quality of life.

Abstract
Iron deficiency anemia (IDA) is a frequent disorder. Also, it may be a sign of underlying serious diseases. Iron deficiency points to an occult or frank bleeding lesion when occurred in men or postmenopausal women. In this study, we aimed to evaluate the diagnostic yield of endoscopy in patients with IDA and to define predictive factors of gastrointestinal (GI) lesions causing IDA. Ninety-one patients (77 women, 14 men; mean age: 43 years) who were decided to have esophago-duodenoscopy and/or colonoscopy for iron deficiency anemia were interviewed and responded to a questionnaire that included clinical and biochemical variables. The endoscopic findings were recorded as GI lesions causing IDA or not causing IDA. Endoscopy revealed a source of IDA in 18.6 % of cases. The risk factors for finding GI lesions causing IDA were as follows: male gender (p= 0.004), advanced age (> 50 years) (p= 0.010), weight loss (over 20% of total body weight lost in last 6 month) (p= 0.020), chronic diarrhea (p= 0.006), change of bowel habits (p= 0.043), epigastric tenderness (p= 0.037), raised carcinoembryonic antigen (CEA) level (normal range: 0-7 ng/mL) (p= 0.039), < 10 gr/dl hemoglobin (Hb) level (p=0.054). None of these risk factors had been present in 21 (23%) women younger than 51 years. In this group, no patient had any GI lesion likely to cause IDA (negative predictive value= 100%). In multivariate analysis, advanced age (p=0.017), male gender (p< 0.01) and weight lost (p=0.012) found that associated with GI lesions in all patients. It may be an appropriate clinical approach to consider these risk factors when deciding for gastrointestinal endoscopic evaluation in iron deficiency anemia.

Abstract
Anemia is a common disorder in the elderly and is associated with increased morbidity and mortality. In elderly subjects, in whom anemia is highly prevalent, there are several aspects, such as a hemoglobin at a level which should concern us limit, or identifying its causes, that are not easy to establish. This review focuses on knowing what is considered to be normal hemoglobin levels in adults and the common causes and potential consequences of anemia in elderly patients. It provides a diagnostic algorithm and an approach to treatment that addresses new treatments such as parenteral iron drugs and erythropoiesis-stimulating agents.

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
There is definitive evidence that iron overload induces oxidative stress and DNA damage, which can enhance carcinogenic risk. However, other evidence suggests that iron deficiency and anemia also increase oxidative stress and DNA damage, which might increase carcinogenesis risk, especially in the gastrointestinal (GI) tract. The aim of this review is to provide essential background information for the accurate interpretation of future research on iron deficiency and increased GI cancer risk. Based on clinical, epidemiological, and experimental evidence, we discuss how iron deficiency might contribute to increased cancer risk through the impairment of several iron-dependent metabolic functions that are related to genome protection and maintenance (e.g., immune responses against cancer-initiated cells, metabolism of toxic compounds, and redox regulation of DNA biosynthesis and repair). Some epidemiological studies have indicated increased risk of GI tumors among individuals with low iron intake or low somatic iron stores, and in vivo data from rodent cancer models indicates the early progression of GI tumors during iron deficiency. Given the preliminary but consistent evidence relating iron deficiency to cancer risk and the fact that iron deficiency affects about one third of the world's population, further studies are needed to define the extent to which iron deficiency might increase GI cancer risk.

Abstract
Anaemia is highly prevalent in elderly populations, particularly in long term care facilities and geriatric wards. Even mild anaemia is associated with adverse health outcomes. Although senescence is considered to be a contributing factor, underlying pathology always has to be thoroughly explored. The most frequent etiologies of anaemia in the elderly are anaemia of chronic disease/inflammation; iron, folate and cobalamin deficiency; and myelodysplastic syndrome. Multiple concomitant etiologies are frequently present. The diagnostic workup is straightforward, not very invasive and should be done systematically. Nutrient deficiencies require complete workup and cure. Anaemia of chronic disease/inflammation ideally is taken care of by treating the underlying disease. If this is not possible and if glomerular filtration rate is significantly decreased, treatment with erythropoietin should be considered. Most cases of myelodysplastic syndrome will benefit from supportive care, but a specific subgroup responds particularly well to oral thalidomide analogues. Transfusions should be avoided.

Abstract
Anemia is a common, multifactorial condition among older adults. The World Health Organization (WHO) definition of anemia (hemoglobin concentration <12 g/dL in women and <13 g/dL in men) is most often used in epidemiologic studies of older adults. More than 10% of community-dwelling adults age 65 years and older has WHO-defined anemia. After age 50 years, prevalence of anemia increases with advancing age and exceeds 20% in those 85 years and older. In nursing homes, anemia is present in 48% to 63% of residents. Incidence of anemia in older adults is not well characterized. Among older adults with anemia, approximately one third have evidence of iron, folate, and/or vitamin B(12) deficiency, another third have renal insufficiency and/or chronic inflammation, and the remaining third have anemia that is unexplained. Several studies demonstrate that anemia is associated with poorer survival in older adults. This review details the distribution and consequences of anemia in older adults and identifies future epidemiologic research needs.

Abstract
Nutritional anemias are important because they are easily reversed and because their underlying causes, most often unrelated to dietary intake, require individualized assessment. Iron-deficiency anemia (IDA) usually results from iron losses accompanying chronic bleeding, including loss to intestinal parasites, or from gastric disorders or malabsorption in the elderly. Cobalamin-deficiency anemia, the only nutritional anemia with predilection for the elderly, nearly always stems from failure of intrinsic factor (IF)-related absorption. Folate-deficiency anemia, the only nutritional anemia usually caused by poor intake, has nearly disappeared in countries that fortify food with folic acid. Copper-deficiency anemia, which usually results from malabsorptive disorders or from medical or nutritional interventions that provide inadequate copper or excess zinc, is uncommon but increasingly recognized. The prevalences of nutritional anemias, which are not always distinguished from non-anemic deficiency, are uncertain. The mean corpuscular volume (MCV) provides an essential diagnostic tool leading to judicious matching of relevant biochemical changes with relevant anemia. Nutritional anemias usually feature abnormal MCV, whereas the predominant anemias in the aged, especially the anemias of chronic disease/chronic inflammation (ACD/ACI), of renal failure, and of unknown causes, are typically normocytic.

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
AIM To evaluate long-term follow-up and predictors of relapse of anemia in a cohort of 102 very elderly patients previously explored for iron-deficiency anemia (IDA). METHODS One hundred and two patients [61 women and 41 men, mean age 82+/-5.8 y (75 to 98)] explored for IDA were prospectively followed up from inclusion (June 2003 to May 2005) until death or May 2006. Survival rate was estimated by the Kaplan-Meier method and compared by the log-rank test. Predictors of recurrence of anemia were identified by multivariate analysis in the 4 following subgroups: unexplained IDA (subgroup 1, n=27), benign lesion (subgroup 2, n=37), cancer treated curatively (subgroup 3, n=28), cancers treated palliatively (subgroup 4, n=10). RESULTS Median follow-up was 20 months. At baseline, main clinical and laboratory data were not significantly different in the 4 subgroups, especially as regards severe comorbidities. Thirty-three patients died, 10 (30%) of them in the first month. Ten (100%) belonged to subgroup 4 versus, respectively, n=7 (26%), n=8 (22%), and n=8 (29%) of patients from subgroups 1, 2, and 3 (P<0.001). No death was directly related to recurrence of anemia. Survival rate at 1 year was 10% in subgroup 4, significantly lower than the other 3 subgroups (subgroup 1: 84%; subgroup 2: 86%; subgroup 3: 78%; log-rank test, P<0.0001). Anemia recurred in 18 cases, and required red cell transfusion in 13 cases. Predictive factors of recurrence of anemia [odds ratio (confidence interval 95%), P] were cancers treated palliatively [14.9 (3-72), P<0.01] and angiodysplasias [4.5 (1.1-18.2), 0.035]. CONCLUSIONS In a cohort of very elderly patients explored for IDA, the mortality rate and the long-term survival were not different for patients with IDA related to a cancer treated curatively than those with unexplained IDA and those with IDA related to a benign lesion. Angiodysplasias and cancers treated palliatively were associated with recurrence of anemia. These results suggest interventionist strategies (including endoscopic investigation and appropriate surgery) for elderly patients with IDA.

Abstract
BACKGROUND Although endoscopy is recommended for patients with iron deficiency anaemia, there is, currently, no consensus on the role of endoscopy for iron-deficient patients without anaemia. The goal of this study was to determine the prevalence of serious gastrointestinal (GI) lesions, identified by endoscopy in patients with iron deficiency and anaemia compared with patients with iron deficiency without anaemia. METHODS One thousand five hundred and eighteen patients with a ferritin value of <or=50 ng/mL and a total iron-binding capacity >or=300 mg/dL were retrospectively investigated using oesophagogastroduodenoscopy and colonoscopy between January 2005 and September 2006. The lesions identified were classified as clinically important according to standard predetermined criteria. RESULTS Among the 1518 cases, 749 patients had anaemia and 769 had normal haemoglobin levels. Clinically important lesions were identified in 24.6% of the patients with anaemia and in 22.8% of the patients without anaemia (P > 0.05). The frequency of lower GI tract lesions (13.6 vs 11.4%, P > 0.05) and upper GI tract lesions (11.9 vs 12.5%, P > 0.05) was similar in the comparisons between the two groups. However, the frequency of malignant GI lesions was higher in the patients with anaemia (5.1 vs 0.7%, P < 0.01). In addition, the patients without anaemia were significantly more likely to have early-stage neoplasia (adenoma, early gastric cancer and Dukes' A and B colon cancer) than were the patients with anaemia (98.4 vs 52.5%, P < 0.01). CONCLUSION The results of this study suggest that patients with iron deficiency should undergo endoscopic evaluation of the GI tract, irrespective of whether they have anaemia. The endoscopic evaluation of the GI tract in patients with iron deficiency without anaemia could provide an opportunity for the detection of early-stage neoplasia at a curable stage.

Abstract
The most severe consequence of iron depletion is iron deficiency anemia (IDA), and it is still considered the most common nutrition deficiency worldwide. Although the etiology of IDA is multifaceted, it generally results when the iron demands by the body are not met by iron absorption, regardless of the reason. Individuals with IDA have inadequate intake, impaired absorption or transport, physiologic losses associated with chronological or reproductive age, or chronic blood loss secondary to disease. In adults, IDA can result in a wide variety of adverse outcomes including diminished work or exercise capacity, impaired thermoregulation, immune dysfunction, GI disturbances, and neurocognitive impairment. In addition, IDA concomitant with chronic kidney disease or congestive heart failure can worsen the outcome of both conditions. In this review, the prevalence of IDA related to confounding medical conditions will be described along with its diverse etiologies. Distinguishing IDA from anemia of chronic disease using hematologic measures is reviewed as well. In addition, current diagnostic strategies that are inclusive of clinical presentation, biochemical tests, and differential diagnosis will be outlined, followed by a discussion of treatment modalities and future research recommendations.

Abstract
BACKGROUND Many hospitalized anemic patients do not undergo appropriate evaluation. We hypothesized that specific clinical variables were likely to be important in triggering evaluation for iron deficiency anemia. METHODS We prospectively identified 637 consecutive anemic patients without acute gastrointestinal bleeding admitted over a three-month period to medical inpatient teams of two teaching hospitals and examined clinical variables that predicted diagnostic evaluation. RESULTS Serum ferritin or serum transferrin saturation (TS) were measured in 43% (271/637) of subjects and were low in 38% (102/271). Predictors of serum ferritin or TS measurement included low hemoglobin concentration and a history of iron supplementation. Predictors of iron deficiency included low hemoglobin concentration (OR 1.9, 95% CI 1.06-3.5) and low mean cell volume (OR 4.6, 95% CI 2.5-8.6). Of 102 patients with iron deficiency anemia, 31% underwent endoscopic evaluation, and 39% had serious gastrointestinal lesions. The only significant predictor of having an endoscopic evaluation was a positive fecal occult blood test (FOBT) (OR 5.2, 95% CI 1.7-16.2). CONCLUSIONS In patients with anemia, tests to ascertain iron status are not appropriately performed in hospitalized patients. Patients found to have iron deficiency anemia who are FOBT-positive undergo endoscopic evaluation more frequently than FOBT-negative patients.

Abstract
INTRODUCTION Patients with anaemia are commonly referred for bidirectional endoscopy. The aim of this study was to determine if any haematological parameters could predict positive findings at endoscopy. PATIENTS AND METHODS A total of 209 patients had bidirectional endoscopies performed for anaemia between September 2002 and March 2004. The endoscopy reports, histology and full blood count results (haemoglobin [Hb], red blood cells [RBCs], packed cell volume [PCV], mean cell volume [MCV] and mean cell haemoglobin [MCH]) were then reviewed. Statistical analysis was performed using non-parametric tests. RESULTS Overall, 197 patients had successful bidirectional endoscopies with 12 requiring completion barium enema. In 48 (23%) of these patients, a cause of anaemia was found with 15 (7.2%) carcinomas detected (2 upper GI and 13 lower GI). There was a significant difference in haemoglobin (9.2 g/dl versus 10.1 g/dl; P = 0.0044), RBCs (3.56 x 10(12)/l versus 3.83 x 10(12)/l; P = 0.0325) and PCV (0.279 l/l versus 0.31 l/l; P = 0.0112) between patients with positive findings at endoscopy and those with a normal investigation. Cancer patients had significantly lower haemoglobin (8.65 g/dl versus 10.1 g/dl; P = 0.0103), RBCs (3.45 x 10(12)/l versus 3.83 x 10(12)/l; P = 0.0179) and PCV (0.27 l/l versus 0.31 l/l; P = 0.0298) compared with patients with normal endoscopies. There was no significant difference in the other haematological parameters between those found to have positive findings and those that had normal endoscopies. CONCLUSIONS Based on this study, the yield of bidirectional endoscopy is low, with haemoglobin and PCV being the most useful haematological indices of significant pathology. Ferritin and MCV did not predict the likelihood of finding a gastrointestinal cause for the anaemia.

Abstract
OBJECTIVES Iron deficiency anemia (IDA) is common in the elderly. It usually results from gastrointestinal (GI) bleeding and requires endoscopic exploration of the gastrointestinal tract. The aim of this prospective study in elderly patients was to evaluate the feasibility of endoscopy, the therapeutic impact, and identify predictors of early mortality. METHODS From June 2003 to May 2005, all patients over 75 years, hospitalized for anemia were screened for iron deficiency. Clinical (including serious comorbidities), biological, endoscopic and therapeutic data were collected. One month after treatment, a follow-up was carried out to assess the tolerance of such investigation and treatment. RESULTS One hundred and eleven patients (69 women, 82.3 +/- 6.4 years) had IDA, 102 (92%) underwent an upper endoscopy and 91 (82%) a colonoscopy. Nine (8%) patients were not investigated because of poor clinical condition (N=4) or dementia (N=5). Of the 75 (68%) patients with an identified source of bleeding, 12 (11%) had a synchronous lesion, 43 (39%) a colorectal source including 31 (72%) colorectal cancer, and 44 (40%) an upper GI source. Sixty-nine (92%) of the 75 patients received at least one of the following treatments: medical (N=27), endoscopic (N=20), and surgical (N=31). Surgery was curative in 28/31 (90%) cases of which 25/27 were colorectal cancers. One month after treatment, overall mortality was 11/111 (10%) and 4/31 (13%) after surgery. Predictors of early mortality (Odd ratio, 95% Confidence Interval) were: a malign cause (42; 3-588), no specific treatment (34; 3-423), at least 2 co-morbidities (20; 1-400). CONCLUSION In an unselected hospitalized population of elderly patients with IDA, endoscopy was generally feasible, allowing identification of a source of bleeding, especially colorectal cancer. A specific treatment was usually possible and proved curative without increase in early mortality.

Abstract
BACKGROUND Patients with unexplained iron deficiency anemia have a greater prevalence of colonic neoplasia, and should be evaluated for a colonoscopy. The approach to patients with anemia without iron deficiency remains unclear. OBJECTIVE To compare the prevalence of colonic neoplasia in anemic patients with normal ferritin (>50 ng/mL), to those with ferritin < or =50 ng/mL, and nonanemic individuals. METHODS Patients referred for colonoscopy for anemia evaluation were stratified into 3 groups: ferritin < or =50 ng/mL, 51-100 ng/mL, and >100 ng/mL. We compared these groups to each other, and to asymptomatic nonanemic individuals undergoing screening colonoscopy. The prevalence of advanced colonic neoplasia was determined for each group using existing records. RESULTS During the study period, 414 patients who underwent colonoscopy for anemia evaluation and 323 nonanemic individuals who underwent colonoscopy for cancer screening met inclusion criteria. Study subjects were mostly men. The prevalence of advanced colonic neoplasia in subjects with ferritin 51-100 ng/mL was 7.2% (95% CI 2.4-17.9%), similar to 7.9% (95% CI 5.1-11.9%) in those with ferritin < or =50 ng/mL. The incidence of advanced colonic neoplasia in subjects with ferritin >100 ng/mL was 1.7% (95% CI 0.1-6.6%), similar to 1.2% (95% CI 0.4-3.3%) in the asymptomatic nonanemic group. After adjusting for age, patients with ferritin < or =50 ng/mL and 51-100 ng/mL were almost 5 times more likely to harbor advanced colonic neoplasia than the other groups. The addition of other laboratory parameters did not improve the predictive value of ferritin. CONCLUSION A ferritin cutoff of 100 ng/mL can be used to determine the need for colonoscopy in men with anemia.

Abstract
Iron deficiency anemia (IDA) is a universal problem involving individuals of all ages and both sexes and is a common cause of referral to medical departments. This anemia is one of the most common types of anemia. IDA impairs growth and intellectual development in children and adolescent. In women IDA is most common in reproductive period because of menstrual and pregnancy iron losses. IDA affects roughly 10-30% of all pregnancies and, among others morbidities, may contribute of developing postpartum depression. Among other adult patient, chronic occult gastrointestinal bleeding is the leading cause of IDA. Approximately, one third of patients with anemia have iron deficiency and up to two thirds of patients with IDA have serious gastrointestinal lesions detected with esophagogastroduodenoscopy and colonoscopy, including 10-15% with malignancy. However, in practice not all anemic patients undergo appropriate diagnostic tests to detect iron deficiency. Furthermore, a substantial proportion of patients with IDA do not undergo endoscopic evaluation. The approach to its investigation and subsequent therapy depends upon a comprehensive understanding of iron metabolism and heme synthesis. Once diagnosis of iron deficiency or IDA is established, evaluation for the cause of anemia must be appropriate performed and treatment must include corrective replenishment of body stores.

Abstract
BACKGROUND Most practice guidelines recommend endoscopic evaluation of the gastrointestinal (GI) tract in men and postmenopausal women with anemia and a serum ferritin less than 20-40 ng/ml. The diagnostic yield of endoscopy in patients with anemia, no GI symptoms or signs, and low normal ferritin is not known. OBJECTIVE The aim of this study was to investigate the yield of upper and lower GI endoscopic evaluations in anemic patients with ferritin levels between 40 and 100 ng/ml. DESIGN A retrospective review of patients' charts was conducted. SUBJECTS AND METHODS Patients at the Veterans Affairs Connecticut Healthcare System who underwent GI endoscopic evaluation for the sole indication of anemia and ferritin in the low normal range (40-100 ng/ml) were included in this study. MEASUREMENTS Incidence of pathology of the upper and lower GI tract was determined. RESULTS We identified 54 male patients who had a ferritin level of 40-100 ng/ml and no GI symptoms or known GI bleeding. Upper GI findings (malignancy, peptic ulcers, Helicobacter pylori gastritis, arteriovenous malformations) were found in 14/47 cases (30%). Lower gastrointestinal findings, including large tubular adenomas and arteriovenous malformation, were identified in 3/53 cases (6.7%). CONCLUSION Our study supports GI endoscopy in anemic patients with ferritin between 40 and 100 ng/ml, even in the absence of GI symptoms or documented bleeding.

Abstract
BACKGROUND Iron deficiency anaemia (IDA) in men and postmenopausal women is mostly due to chronic gastrointestinal blood loss. One of the most common missed lesions while performing upper endoscopy in the work-up of IDA, are Cameron lesions, located at the neck of a large hiatal hernia. AIMS Description of the bio-clinical and endoscopic findings of a large hiatal hernia, diagnosed in patients presenting with iron deficiency anaemia. Furthermore, a review of the literature concerning the diagnostic and therapeutic management of these patients will be outlined. STUDY We retrospectively evaluated 36 patients, presenting with IDA (hemoglobin < 10 g/dl) associated with a large hiatal hernia. RESULTS Cardiopulmonary complications of anaemia were the presenting symptoms, rather than gastrointestinal related complaints or bleeding. Cameron lesions were visualized only in 18 (50%) of our patients at their first presentation. There was no obvious correlation between the presence of Cameron lesions and visible gastrointestinal blood loss. Initially, almost all of our patients were treated medically. Seven underwent surgical repair of the hiatal hernia and all remained asymptomatic afterwards. CONCLUSION We conclude that a hiatal hernia, with or without visible Cameron lesions, is a real and maybe underestimated cause of IDA. Finding a large hiatal hernia on upper endoscopy, together with a negative colonoscopy, completes the diagnostic work-up of IDA in most of these elderly patients. Currently, no guidelines concerning the optimal therapeutic management of this problem are available. Therapy may depend upon the need of transfusion, the efficiency of medical treatment, the risks of surgery and the preference and general condition of the patient.

BACKGROUND Iron deficiency anaemia (IDA) may be a sign of significant gastrointestinal disease, and delayed diagnosis may result in chronic morbidity. Studies in patients referred to hospital for investigation of their anaemia have shown that 5%-15% have a gastrointestinal cancer but there are few studies of patients presenting to primary care. Factors influencing further investigation in these patients have not previously been identified. PATIENTS AND METHODS A cohort of patients presenting to their general practitioners (GPs) with IDA was identified and clinical outcomes recorded. Logistic regression was used to determine which factors influenced GPs to investigate the anaemia. RESULTS 43% of patients had investigations within three months and serious pathology was found in 30% of these; 13% of patients were considered unfit for further investigation and 8% refused to have any. Independent predictors of non-investigation were a mild anaemia (odds ratio (OR) 0.38, confidence interval (CI) 0.23 to 0.61, p<0.001), female gender (OR 0.49, CI 0.3 to 0.8, p = 0.004), a previous history of anaemia (OR 0.39, CI 0.24 to 0.64, p<0.001), and age <65 years (OR 0.44, CI 0.26 to 0.74, p = 0.002). During the entire study period gastrointestinal cancer was diagnosed in 48 patients (11%); 17% of men had colorectal cancer. Of 263 patients alive at 12 months without a confirmed diagnosis, 113 (43%) had recurrent or persistent anaemia during the study period. CONCLUSION Although the overall prevalence of gastrointestinal cancer in patients presenting to primary care is similar to that seen in secondary care, the diagnosis may be delayed due to lack of appropriate investigations resulting in significant morbidity.
