Haematologica 2011; 96:1761. Not to be confused with high-molecular-weight dextran (discontinued); 4-wk interval recommended before MRI. This is the largest study showing an impact of systemic inflammation on iron absorption in anemic IBD patients. The study design has been reported previously [15]. Vermeire S, Van AG, Rutgeerts P. Laboratory markers in IBD: useful, magic, or unnecessary toys? I. In conclusion, assessment of inflammatory status in terms of easily available CRP measurements could be useful in identifying patients who may initially benefit from first-line i.v. While iron deficiency remains the most common cause of anemia worldwide, low iron stores are associated with symptoms regardless of the presence of typical microcytic, hypochromic anemia and may be hard to recognize in patients with concurrent inflammation. Because of Ferritin is an acute phase reactant, It may increase disproportionately relative to iron stores.Accordingly in this case, serum . WHO guidelines recommend a ferritin level <15 g/L as a sign of absolute ID in adults,8 although a cutoff of 30 g/L is more often used because of its higher sensitivity (92%) and high specificity (98%).9 Unfortunately, its high accuracy is lost in the presence of inflammation. As shown in our and one other study [25], responsiveness to i.v. To be absorbed, the folate must be deconjugated by a brush border peptidase of enterocytes; the intestinal mucosal . You have had a history of viral flu. Normal or high levels of ferritin do not exclude iron deficiency, because ferritin acts as an acute phase reactant. MATTHEW W. SHORT, LTC, MC, USA, AND JASON E. DOMAGALSKI, MAJ, MC, USA. The https:// ensures that you are connecting to the Crohns disease, Ulcerative colitis, Inflammatory bowel disease, C-reactive protein, Iron deficiency, Iron therapy, Anemia. Burning pain in the hands or feet. Lastly, a recently presented investigation from our group has shown that IBD patients with ACD respond differently to oral iron treatment compared to those with IDA [12]. Statistical significance was assumed to be at p<0.05. 1Department of Gastroenterology, University Hospital Birmingham, Vincent Drive, Birmingham, B15 2TH UK, 2Interdisciplinary Crohn Colitis Centre Rhein-Main, Schifferstrasse 59, 60594 Frankfurt am Main, Germany, 3Department of Gastroenterology, Heartlands Hospital, Birmingham, B9 5SS UK, 4Division of Gastroenterology and Hepatology, Department of Medicine III, Medical University of Vienna, Whringer Grtel 18-20, 1090 Vienna, Austria, 5Vifor Pharma Ltd., Flughofstrasse 61, 8152 Glattbrugg, Switzerland. Statistical presentation includes least-squares means (LS means), standard errors (SE) split by baseline CRP or IL-6 (high vs. low) group, and associated level of significance. 12- (US) to 24- (Europe) wk interval recommended before MRI. Erichsen K, Hausken T, Ulvik RJ, Svardal A, Berstad A, Berge RK. Phosphate binder, approved for use in ID in ndCKD. All adult men and postmenopausal women with iron deficiency anemia should be screened for gastrointestinal malignancy. Our results are supported by the findings of three other studies. Iron is an essential mineral needed to make red blood cells, and low amounts can lead to anemia, causing headaches, pale skin, fatigue, and other symptoms. ferric carboxymaltose (FCM) with oral ferrous sulfate (FS) in IBD patients, were retrospectively analyzed. In multiple myeloma, the level of one type may be high while the others are low. This should also be considered in the selection of diagnostic markers for assessment of iron status. The guideline may not apply to all patients with chronic inflammatory conditions (CICs), such as obesity, chronic kidney disease (CKD), liver disease, and heart failure (HF), in whom an increase in CRP is frequently absent, or where AGP measurements are not routinely available. Low transferrin saturation (TSAT), calculated by serum iron divided by total iron-binding capacity (TIBC), indicates iron deficiency. Because the anemia is mild and the history and laboratory values are consistent with iron. Serum protein electrophoresis (SPEP) is a test that measures the antibodies in the blood and can find a monoclonal antibody. Blood loss may also increase with frequent blood draws during an admission or in equipment circuits, in patients on hemodialysis, for example. The measurement of evaluated variables by local laboratories in this multicenter study may have added some additional variability into the data. Women should be screened during pregnancy, and children screened at one year of age. For children at low risk for acute inflammation, concurrent measurement of CRP may not be necessary. A randomized, open-label, non-inferiority study of intravenous iron isomaltoside 1,000 (Monofer) compared with oral iron for treatment of anemia in IBD (PROCEED). Can iron deficiency cause high CRP? Copyright 2013 by the American Academy of Family Physicians. Data from a previously published phase III trial were retrospectively analyzed after stratification of patients according to baseline CRP (>4 vs. 4mg/L) and IL-6 (>6 vs. 6pg/mL) levels. Gasche C, Waldhoer T, Feichtenschlager T, Male C, et al. A growing portfolio is currently available in the United States: low-molecular-weight iron dextran, iron sucrose, ferric gluconate, ferumoxytol, ferric carboxymaltose (FCM), and ferric derisomaltose (previously known as iron isomaltoside; Table 3). In ID, iron stores are progressively exhausted before red cell morphology of hemoglobin levels are affected, and patients may experience early symptoms such as fatigue, reduced cognitive performance, and exercise intolerance. Elevated CRP 10 mg/L occurred in 3.3% (95% CI: 2.5 to 4.2). Ferritin and TSAT ranges reported by studies that evaluated BM iron in patients with CICs. In CICs, polypharmacy is the rule, and chronic use of some medications can predispose patients to GI bleeding (eg, corticosteroids, nonsteroidal anti-inflammatory drugs, aspirin, and anticoagulants), and use of other medications can impair iron absorption (eg, proton pump inhibitors and laxatives). Ferritin is an acute-phase protein and its serum levels are elevated during inflammation, reflecting the inflammatory state rather than iron stores. Iron deficiency at any yearly time point was associated with higher increases in hs-CRP (mean difference in change: 1.62 mg/L, 95%CI 0.98-2.26, P < . Patients with BMID have ferritin <160 g/L and TSAT <20%. As a library, NLM provides access to scientific literature. In clinical practice, many patients receive initial treatment with iron tablets although intravenous (i.v.) Skin discoloration from extravasation is also a possible complication and patients should be informed of that particular risk. 1-10%: fecal discoloration, constipation, diarrhea, abdominal pain, nausea, vomiting. She asked whether she could take iron tablets or should receive iron injections, which she had heard carry a risk for allergic reactions. Acute-phase reactions lead to substantial changes in iron metabolism and are characterized by high levels of ferritin and hepcidin and low levels of iron and transferrin. Data Sources: A PubMed search was completed in Clinical Queries using the key terms iron deficiency and anemia. Its indication in clinical practice by itself has become rare with the ease of the use of ferritin, but it may occasionally prove useful in patients who undergo BM sampling for other reasons. Patients can also call 8-1-1 to speak . Sharma N, Begum J, Eksteen B, Elagib A, et al. This prospective statistical approach resulted in a cutoff at 4mg/L (high CRP: >4mg/L; low CRP: 4mg/L) and ensured an equal number of patients in both groups. Myelodysplasia may also be associated with an increased RDW. Electrophoresis The antibody produced by myeloma cells is abnormal because it is monoclonal (all the exact same ). Once iron deficiency anemia is identified, the goal is to determine the underlying etiology. Correspondence Kleber Yotsumoto Fertrin, University of Washington, 825 Eastlake Ave, E MS CE3-300, Seattle, WA 98109; e-mail: kleber@uw.edu. Patients with iron deficiency anemia are often asymptomatic and have limited findings on examination. Because malnutrition and inflammation are associated with low . Iron deficiency is characterized by microcytosis with an elevated RBC distribution width. Long-term use of aspirin or other nonsteroidal anti-inflammatory drugs, Cameron ulcer (i.e., ulcer in large hiatal hernia), Based on weight and amount of desired change in hemoglobin, One to three tablets two or three times per day. Wiesenthal M, Dignass A, Hartmann F, Iqbal T, Stein J. Serum hepcidin levels predict intestinal iron absorption in IBD patients. Inflammation with increased cytokine production causes upregulation of liver hepcidin (H), which binds to ferroportin (F). In . Second European evidence-based consensus on the diagnosis and management of ulcerative colitis part 3: special situations. Least-squares meansstandard errors, adjusted for gender and baseline Hb. By contrast, an iron saturation <5% and an elevated . The World Health Organization (WHO) defines anemia as hemoglobin <13 g/dL and <12 g/dL in adult men and nonpregnant women, respectively, 1 a well-known trigger for an investigation of ID. Standardized AUC analysis confirmed a statistically significant difference between the CRP groups in oral iron-treated patients (high vs. low CRP, LS means: 21.3 vs. 29.3; p=0.012). sharing sensitive information, make sure youre on a federal Patients with high baseline CRP achieved a lower Hb response with oral iron therapy. Causes include inadequate iron intake, decreased iron absorption, increased iron demand, and increased iron loss (Table 2).5,7,18,19, Premenopausal women with a negative evaluation for abnormal uterine bleeding can be given a trial of iron therapy. High levels of 40-200 mg/L ?will occur in active inflammation or chronic bacterial infection. In hepatocytes and macrophages, iron is also trapped intracellularly and is stored as iron-rich ferritin, whereas macrophages increase iron-poor serum ferritin in circulation. Author disclosure: No relevant financial affiliations to disclose. Occasionally, it can cause chest pain, a fast heartbeat and shortness of breath. In addition, gut luminal iron may induce oxidative stress [13] and increase local disease activity in IBD [3, 14]. official website and that any information you provide is encrypted 1. Mean baseline Hb and laboratory measures of inflammatory markers were similar between treatment groups [15]. Not surprisingly, a trend toward a positive correlation (p=0.075) between baseline CRP and serum ferritin levels was observed in the study. ALT, alanine transferase; AWP, average wholesale price (reported on UpToDate.com; last accessed 25 September 2020); GGT, -glutamyl transferase; LMW, low-molecular-weight; MRI, magnetic resonance imaging; NS, normal saline (0.9% sodium chloride); USD, US dollars. The patient underwent an upper endoscopy and colonoscopy, and a bleeding gastric ulcer was detected, for which omeprazole was prescribed. Iron deficiency was defined by soluble transferrin receptor levels > 28.1 nmol/L and baseline anemia by hemoglobin levels < 130 g/L for men and < 120 g/L for women. 8600 Rockville Pike CRP is a readily available laboratory value that is usually included in the routine assessment of IBD patients. Among iron tablet-treated patients, Hb increase was significantly smaller in the high- versus low-CRP subgroup (1.1 vs. 2.0, 2.3 vs. 3.1, and 3.0 vs. 4.0g/dL at weeks 2, 4, and 8, respectively; all p<0.05). The two most common causes of anemia in IBD patients are absolute iron deficiency and anemia of chronic disease (ACD; also referred to as anemia of chronic inflammation) [1, 3]. SKD received speaker honoraria from Vifor International. Federal government websites often end in .gov or .mil. In your attached reports (attachments are hidden to protect the patient's identity) ferritin level is low, and TIBC (total-iron binding capacity) increased, which is suggestive of mild iron deficiency anemia. A total of 196 patients were evaluated (oral iron: n=60; i.v. Symptoms People with high platelet levels often don't have signs or symptoms. by "Nutrients"; Food/cooking/nutrition C-reactive protein Health aspects EDTA Ethylenediaminetetraacetic acid Ferritin Functional foods Hemoglobin Hemoglobins Iron deficiency anemia Care and treatment . These effects may be reduced when iron is taken with meals, but absorption may decrease by 40 percent.1 Medications such as proton pump inhibitors and factors that induce gastric acid hyposecretion (e.g., chronic atrophic gastritis, recent gastrectomy or vagotomy) are associated with reduced absorption of dietary iron and iron tablets.31, Parenteral therapy may be used in patients who cannot tolerate or absorb oral preparations, such as those who have undergone gastrectomy, gastrojejunostomy, bariatric surgery, or other small bowel surgeries. The Biomarkers Reflecting Inflammation and Nutrition Determinants of Anemia (BRINDA) research group found that a regression correction of ferritin using CRP >5 mg/L and AGP >1 g/L increased the prevalence of ID by 3% to 7%, even in countries with a low burden of infection, such as the United States,15,16 and a different regression correction using CRP and albumin increased the prevalence of ID from 7% to 24% in another study.17 Therefore, in areas of widespread inflammation or infection, the 2020 WHO guidelines18 strongly endorse the measurement of CRP and AGP, but make a conditional recommendation to use a ferritin threshold of 70 g/L to define iron deficiency in patients with CRP >5 mg/L or AGP >1 g/L or to implement arithmetic or regression correction of ferritin levels based on those markers. Assessment of iron stores using ferritin and TSAT in CICs. A 56-year-old woman was referred for evaluation of anemia. For both markers, there was no significant relationship with baseline Hb levels (CRP: R=0.0191, p=0.791; IL-6: R=0.0393, p=0.590). Increased CRP and significantly elevated ESR support ACD. CRP is routinely measured in IBD patients and forms part of the recommended diagnostic workup in patients with anemia (hemoglobin [Hb]<12g/dL in non-pregnant women, <13g/dL in men) [3, 9]. iron supplementation is often preferable. However, the potential of hepcidin as a biomarker is limited, even though it is a more direct measure of iron sequestration than the well-established but unspecific inflammatory marker CRP. Consider dietitian referral. In CD patients who received oral iron (n=16), early Hb increase was significantly smaller in the high-CRP group at week 2 (Fig. the contents by NLM or the National Institutes of Health. Iron deficiency anemia is diminished red blood cell production due to low iron stores in the body. A week later, she called the office to report that she was still feeling weak and wondered whether her anemia was getting worse. Cells of the immune system release pro-inflammatory cytokines, predominantly interleukin-6 (IL-6), which in turn up-regulate the expression of hepcidin, a key regulator of iron homeostasis. iron (CD: n=40; UC: n=96). Of note, baseline levels of CRP and IL-6 strongly correlated with each other (R=0.2442; p=0.0007). Anaemia is defined by the World Health Organization as a Hb level below 120 g/L in non-pregnant females and 130 g/L in males, which is consistent with the definition of anaemia in the National Blood Authority Patient Blood Management Guidelines. which is commonly affected by CD. Patients with iron stores estimated to be low (in black and red) should be considered for iron supplementation. A more practical approach is to recheck the patient periodically; no further follow-up is necessary if the patient is asymptomatic and the hematocrit level remains normal.7, There is no universally accepted threshold for transfusing packed red blood cells in patients with iron deficiency anemia. Iron deficiency anemia is a common complication of chronic kidney disease (CKD). Iatrogenic iron overload is another concern in the absence of reliable ferritin levels. Despite a ferritin level of 89 g/L (considered normal for healthy individuals), the presence of ferritin <200 g/L, a TSAT <20% in the presence of several CICs (liver disease, controlled rheumatoid arthritis, and stage 3 ndCKD), and hypoproliferative normochromic, normocytic anemia supported a diagnosis of IDA. The treatment of absolute IDA has been extensively reviewed elsewhere,26,27 but the mainstay of the recommendations for ID in patients with CIC must include investigating underlying causes and implementing appropriate iron supplementation. Chest pain. Anemia can have many different causes. The diagnosis of ID in this population can be complicated by the coexistence of systemic inflammation or other nutritional deficiencies which may mimic ID. Further evaluation should be based on risk factors (Figure 2).10,15,1721, Excessive menstruation is a common cause of iron deficiency anemia in premenopausal women in developed countries; however, a GI source (particularly erosive lesions in the stomach or esophagus) is present in 6 to 30 percent of cases.20,22,23 If the gynecologic workup is negative and the patient does not respond to iron therapy, endoscopy should be performed to exclude an occult GI source.20,22,23, Excessive or irregular menstrual bleeding affects 9 to 14 percent of all women and can lead to varying degrees of iron deficiency anemia.24 Etiologies include thyroid disease, uncontrolled diabetes mellitus, polycystic ovary syndrome, coagulopathies, uterine fibroids, endometrial hyperplasia, hyperprolactinemia, and use of antipsychotics or antiepileptics.

Gisbert JP, Gomollon F. Common misconceptions in the diagnosis and management of anemia in inflammatory bowel disease. She eventually completed her treatment with hemoglobin of 10.4 g/dL, ferritin of 359 g/L, and TSAT of 35%. Searches were also performed using Essential Evidence Plus, the Cochrane database, the National Guideline Clearinghouse database, the Trip Database, DynaMed, and the Agency for Healthcare Research and Quality evidence reports. Patients may be asymptomatic or present with nonspecific symptoms including fatigue, irritability, and dizziness. As the test subjects were not anemic, only a single dose of oral iron was administered. Efficacy and tolerability of oral iron therapy in inflammatory bowel disease: a prospective, comparative trial. government site. In patients with chronic diarrhea, high epithelial turnover impairs absorption and mucosal inflammation can cause bleeding. Prevalence and management of cancer-related anaemia, iron deficiency and the specific role of intravenous iron. CRP . Can anemia cause high CRP and ESR? Various ferritin cutoff values have been recommended to help detect ID in different patient populations, such as in those with CKD, HF, and IBD.3 There is a general consensus that the usual ferritin cutoff of 30 g/L is inappropriate in the presence of a CIC but the recommended ferritin values range between 50 and 500 g/L across guidelines. The search included meta-analyses, randomized controlled trials, controlled trials, and reviews. Low-molecular-weight iron deficiency, iron sucrose, and ferric gluconate may require several shorter infusions, whereas the remainder have become increasingly popular because of the lower number of visits required to administer high-dose infusions, despite the higher cost of the medication. An acute-phase reaction is triggered by proinflammatory cytokines, particularly interleukin-6 (IL-6), IL-1, and tumor necrosis factor (TNF), in response to infection or tissue injury, making hepatocytes increase the synthesis of acute-phase proteins,5 including ferritin and hepcidin. Diagnosing and treating iron deficiency become more of a challenge because markers of iron status are influenced by low-grade inflammation present in common conditions, such as chronic kidney disease, cirrhosis, or heart failure. In patients with HF, TSAT >20% essentially excluded the possibility of BMID, regardless of ferritin levels.23 In patients with nondialysis CKD (ndCKD) who underwent BM evaluation, TSAT below 20% had only 50% sensitivity but 83% specificity to detect BMID, and the specificity for BMID improved to 98% if associated with a ferritin level <100 g/L, with a reduction in sensitivity to 33%. Our results suggest that CRP may be useful to identify IBD patients who can benefit from first-line treatment with i.v. Sharma N, Laftah AH, Brookes MJ, Cooper B, Iqbal T, Tselepis C. A role for tumour necrosis factor alpha in human small bowel iron transport. iron was mainly independent of baseline CRP. Published data suggest that IL-6 levels may be more relevant in CD than those in UC patients [29]. Patients with an underlying condition that causes iron deficiency anemia should be treated or referred to a subspecialist (e.g., gynecologist, gastroenterologist) for definitive treatment. In patients with celiac disease, a correlation between iron deficiency and increased expression of ferritin in enterocytes of the duodenum was observed, indicating a link between iron absorption and local mucosal inflammation [20]. Nevertheless, ESR varies with hematocrit and is driven mostly by the production of fibrinogen and immunoglobulins, which last for several days in the circulation, whereas CRP is mainly produced by the liver in response to cytokines, particularly IL-6, and has a much shorter half-life; discrepancies between ESR and CRP are unsurprisingly common.12 CRP >50 mg/L is frequent in bacterial infections, making it an excellent marker of acute inflammation, whereas the less-noted -1-acid glycoprotein (AGP) increases later in the inflammatory process and is more suitable for confirming chronic inflammation.13 Because ferritin increases >5 times in patients with CRP >80 mg/L than in those with CRP <10 mg/L,14 studies have examined the possibility of correcting ferritin for inflammatory activity. The relevance of a single significant difference between the high- and low-CRP groups among i.v. Studies that reported only ferritin levels are represented by red lines beneath the x-axis that encompass the range, and means are represented by diamonds situated on the lines. Data from a randomized, multicenter, controlled phase III trial [15], which compared the efficacy and safety of i.v. . Iron depletion occurs commonly and is related to associations among blood loss, low dietary iron intake, and malabsorption. Initial Hb response to oral iron was significantly lower in IBD patients with a high baseline CRP level (>4mg/L), compared to those with low baseline CRPat least for the first 2months of treatment. Relationship of functional and antigenic interleukin 6 to disease activity in inflammatory bowel disease. ID is defined as a health-related condition in which iron availability is insufficient to meet the bodys needs and which can be present with or without anemia,3(p1069) and it is fundamentally recognized that IDA is simply the most advanced stage of ID. Most IBD patients become iron deficient at some stages of the disease [3, 4]. Examples include: Headache. Hb response to i.v. Intravenous iron can for the most part overcome the hepcidin block [24] and is therefore advisable in IBD patients with pronounced disease activity [3, 9]. A comparison between absolute ID (Figure 1) and FID (Figure 2) shows that both have low serum iron and elevated ferritin, and low TIBC characterizes FID. Previously recommended, but currently not on label; >20%: hypotension, vomiting, nausea, headache, diarrhea, injection site reaction, muscle cramps; 1-10%: hypotension, edema, chest pain, hypertension, dizziness, headache, pruritus, rash, diarrhea, nausea, constipation, vomiting, abdominal pain, hypersensitivity reaction, cough, dyspnea, fever. Haemoglobin concentrations for the diagnosis of anaemia and assessment of severity, Iron deficiency across chronic inflammatory conditions: International expert opinion on definition, diagnosis, and management, Plasma ferritin determination as a diagnostic tool, Ferritin is secreted via 2 distinct nonclassical vesicular pathways, Serum ferritin is derived primarily from macrophages through a nonclassical secretory pathway, Vitamin and Mineral Nutrition Information System (WHO/NMH/NHD/MNM/11.2). These values were rounded down to the next integer. Another common symptom is restless leg syndrome (RLS), which is an unpleasant urge to move the legs during periods of inactivity. Prominent anisocytosis and poikilocytosis, including pencil-shaped RBC forms, on the peripheral smear, tend to favor iron deficiency over ACD. Fever (p<0.0001), arthritis (p<0.03) were significantly related and CRP was elevated (p<0.04) in cases with high SLEDAI (severe flare). If initial endoscopy findings are negative and patients with iron deficiency anemia do not respond to iron therapy, repeat upper and lower endoscopy may be justified. Iron deficiency anemia (IDA) is the most common cause of anemia worldwide. The .gov means its official. 2b). This study aimed to investigate the effect of baseline systemic inflammation (as assessed by CRP and IL-6) on the treatment efficacy of iron supplementation comparing tablets to intravenous injections. Anemia of chronic disease. In clinical practice, CRP levels 5 mg/L are usually considered elevated. Mild (1.8-2.5 mg/dL or 0.6-0.8 mmol/L) to moderate (1.0-1.8 mg/dL or 0.3-0.6 mmol/L) decreases in phosphate levels can be managed with dietary changes to increase ingestion of phosphate-rich food (eg, dairy, poultry) and/or oral potassium phosphate. The diagnosis of iron deficiency anemia is confirmed by the findings of low iron stores and a hemoglobin level two standard deviations below normal. Screening serology for celiac disease should be considered for all adults with iron deficiency anemia. This study investigated whether systemic inflammation at initiation of treatment (assessed by C-reactive protein [CRP] and interleukin-6 [IL-6] measurements) predicts response to iron therapy. Based on the data from this relatively small patient group, patients with high CRP levels take longer to respond to oral iron but eventually reach similar responses at 3months. Most patients with CICs in association with true ID are found to have TSAT<20% and ferritin <200 g/L (red). Less commonly, very high platelet levels may cause bleeding. Iron deficiency anemia signs and symptoms may include: Extreme fatigue Weakness Pale skin Chest pain, fast heartbeat or shortness of breath Headache, dizziness or lightheadedness Cold hands and feet Inflammation or soreness of your tongue Brittle nails Unusual cravings for non-nutritive substances, such as ice, dirt or starch Our current findings are in line with the established link between inflammation and iron sequestration. Preventing Iron-Deficiency Anemia. Parenteral iron is often used because numerous systematic reviews have identified the superiority of parenteral iron over oral iron for patients with IBD, HF, CKD, or perioperative anemia. Summary and statistical analyses were performed using SAS version 8 or later and R version 3.0.2. Iron deficiency anemia (IDA) is the most common acquired anemia and should be the first consideration in a patient with unexplained anemia. Tumour necrosis factor alpha causes hypoferraemia and reduced intestinal iron absorption in mice. Hepcidin regulates cellular iron efflux by binding to ferroportin and inducing its internalization. The type of iron deficiency anaemia, but not the underlying disease, predicts intestinal iron absorption in IBD patients. for 12weeks) [15]. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Low iron also upregulates hepatic production of transferrin, resulting in high TIBC, contributing to low TSAT. Methods: We collected all patients seen at a university hospital in 2004 with at least one CRP level above 500 mg/l and retrospectively analyzed their electronic files, focusing on patient characteristics, clinical . Correlations were estimated with Pearsons product-moment method. Measurement of the serum ferritin level is the most accurate test to diagnose iron deficiency anemia. In some instances, lesions may not be detected on initial examination (e.g., missed mucosal erosions in a large hiatal hernia, suboptimal preparation for colonoscopy, inadequate biopsy of a suspected lesion).13 Colonoscopy can fail to diagnose up to 5 percent of colorectal tumors.13, Additional evaluation of the small intestine is not necessary unless there is inadequate response to iron therapy, the patient is transfusion dependent, or fecal occult blood testing suggests that the patient has had obscure GI bleeding with the source undiscovered on initial or repeat endoscopy.30 In these cases, further evaluation with capsule endoscopy should be considered.30 Enteroscopy is an upper endoscopy procedure using a longer scope to visualize the proximal jejunum; it should be reserved to treat or biopsy lesions identified by capsule endoscopy.
