We compared the ability of soluble serum transferrin receptor (TfR) concentration, quantified using the R&D Systems (Minneapolis, MN) enzyme-linked immunosorbent TfR assay, with other, more traditional indicators of iron status (total iron binding capacity [TIBC], mean corpuscular volume [MCV], percent transferrin saturation [%TS], RBC distribution width [RDW], and serum iron concentration . The STFR will be increased in iron . Iron Deficiency Anemia: Evaluation and Management ... In patients with anemia in rheumatoid arthritis .

PDF Soluble Transferrin Receptor Discriminates Iron Deficiency ... Am J Clin Pathol 2001;115:112-118 . The aim of this study was to assess the value of the soluble serum transferrin receptor (sTfR) and the transferrin receptor-ferritin index (sTfR/logF) as new markers of iron status in patients with anemia of chronic kidney disease (ACKD) both treated and not treated with recombinant human erythropoietin (rHuEPO) therapy. Soluble Transferrin Receptor Discriminates Iron Deficiency Anemia from Anemia of Chronic Disease in Leukemic and Breast Cancer Patients 1Akanni E Olufemi, 2Mabayoje V. Olatunji, 3Oguntola A. Saliu 3Adeoti M. Layiwola, 4Adedeji A. Lawrence and 5Oparinde D. Pius. In general, to increase sensitivity and specificity, the measurement of serum soluble transferrin receptor should be performed in combination with other tests of iron status, including ferritin, TIBC, and serum iron (refer to . Refer to UpToDate topics on anemia for further details of the evaluation and interpretation. The dual "face" of the anemia in IBD remains a serious problem for the IBD practitioner, as its two main subgroups (iron deficiency anemia, IDA, and anemia of chronic disease, ACD) are rather often mixed and overlapped, providing a substantial difficulty in . sTfR, Soluble transferrin receptor; Tf, transferrin. It can be inferred that a ratio of >1.4 indicates co existence of iron deficiency anemia with anemia of chronic disease while ratio of up to 1.3 indicates anemia of chronic disease only. (PDF) Soluble transferrin receptor-ferritin index in the ... For instance, soluble transferrin receptor protein is a peptide deriving from transmembrane transferrin receptor, which is expressed in iron requiring cells; therefore, soluble transferring receptor concentration is directly proportional with cellular receptor density, revealing total iron demand. Hemotology Chapter 12 Flashcards | Quizlet Increased synthesis of TfR For this purpose, new tools are available today. N ENGL J MED 352;10. Soluble Transferrin Receptor (sTfR), Serum - Laboratory ... Nephrol Dial Transplant 2002; 17: 1063-1069. Comparing groups with each other revealed significant differences (p<0.05). Soluble Transferrin Receptor Level Improved differential diagnosis of anemia of chronic disease and iron deficiency anemia: A prospective multicenter evaluation of soluble transferrin receptor and the sTfR/log ferritin index. TIPS FOR DEALING WITH ANEMIA OF CHRONIC DISEASE (ACD) Serum soluble transferrin receptor results from cleavage of cell surface transferrin receptors, most of which are on developing red cells. sTfR is a truncated form of the tissue receptor and exists as a transferrin - receptor complex (1, 2). Other tests include folate, vitamin B12, blood smear, and blood in stools. STFR is useful in distinguishing anemia of chronic disease from iron deficiency. The sTfR concentration was determined in 118 patients divided according to their inflammatory statu … UpToDate, electronic clinical resource tool for physicians and patients that provides information on Adult Primary Care and Internal Medicine, Allergy and Immunology, Cardiovascular Medicine, Emergency Medicine, Endocrinology and Diabetes, Family Medicine, Gastroenterology and Hepatology, Hematology, Infectious Diseases, Nephrology and . Thomas L, Thomas C. Anemia in iron deficiency and disorders • There is evidence that soluble transferrin receptor of iron metabolism. 52 In contrast . The etiology for the anemia may be multifactorial and, in the setting of inflammatory process when the ferritin is increased, it is difficult to diagnose iron deficiency anemia. Soluble transferrin receptors in anemia of chronic disease are not significantly different from normal, because transferrin-receptor expression is negatively affected by inflammatory cytokines. We also have examined the results in relation to bone marrow iron status in an attempt to explain the reported difference between serum soluble transferrin receptor (sTfR) values in anemia of chronic disease (ACD) and iron deficiency anemia (IDA) in patients with RA. women <12 g/dL; men <13 g/dL. 1. 65, pp. Synonyms: sTfR. View at: Google Scholar Soluble transferrin receptor (sTfR) is a measure of iron deficiency and is particularly useful in persons with inflammation, infection, or chronic disease, where ferritin levels do not correlate with true iron levels. Transferrin Receptor. The degree of anemia in ACD is typically mild to moderate (Hb 8 g/dL to 11 g/dL). . Improved differential diagnosis of anemia of chronic disease and iron deficiency anemia: a prospective multicenter evaluation of soluble transferrin receptor and the sTfR/log ferritin index. The soluble transferrin receptor (sTfR) immunoassay should not be used for the routine clinical evaluation of patients for iron status when ferritin immunoassay (FERR / Ferritin, Serum) would be appropriate, such as in the absence of confounding pathologies (inflammation, infection, chronic disease, or malignancy). On Monday, December 17, 2001, the Clinical Chemistry Laboratory of the Department of Pathology will begin accepting specimens for the Soluble Transferrin Receptor assay (STFR). The soluble transferrin receptor (sTfR) test is primarily ordered to help distinguish between anemia that is caused by iron deficiency and anemia that is caused by inflammation or a chronic illness (so-called anemia of chronic disease or inflammation). 무엇보다 혈청 TfR은 철결핍성 빈혈에서 증가하고 만성질환에 영향 받지 않는다는 사실. The soluble transferrin receptor (sTfR) immunoassay should not be used for the routine clinical evaluation of patients for iron status when ferritin immunoassay (FERR / Ferritin, Serum) would be appropriate, such as in the absence of confounding pathologies (inflammation, infection, chronic disease, or malignancy). Role of soluble transferrin receptor and soluble transferrin receptor index in diagnosing iron deficiency anemia in patients with chronic kidney disease. Summary Ferritin concentration, as a parameter of iron status that is commonly used in the diagnosis of iron deficiency anaemia (IDA), often has limited values if the iron deficiency is accompanied by inflammatory disease. An increased soluble transferrin receptor is helpful in diagnosing Iron Deficiency Anemia in a pt that also has Anemia of Chronic Disease. Soluble transferrin receptor (sTfR) is a biochemical parameter used for the detection of iron deficiency in situations where ferritin has limited diagnostic value owing to the present chronic disease. Severe anemia may indicate an alternative or coexisting cause (e.g., blood loss, iron deficiency anemia, or a primary hematologic disorder). Determination of serum soluble transferrin receptor (sTfR) is proposed to distinguish between iron-deficiency anemia and anemia of chronic disease. NKF-K/DOQI Clinical Practice Guidelines For Anemia Of Chronic Kidney Disease: Update 2000. The circulating sTfR concentration is proportional to cellular expression of the membrane-associated TfR and increases with increased cellular iron . Serum soluble transferrin receptor increases in iron deficiency and is usually unaffected by chronic disease states. Anemia of chronic disease (ACD) and iron deficiency anemia (IDA) are the most prevalent forms of anemia and often occur concurrently.
