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 [SIC...

Background. Chronic Helicobacter pylori infection and iron-deficiency anemia (IDA) are common in adults. Although the most common causes of IDA usually arise from the gastrointestinal tract, the association between chronic Helicobacter pylori infection and anemia remains unclear. Aim. To evaluate the association of chronic Helicobacter pylori infection and IDA. Materials and Methods. We enrolle...

The role of Tumor Necrosis Factor alpha, Malondialdehyde and serum Iron in inducing anemia in Tuberculosis patients was studied. The present study was conducted in the Department of Biochemistry, Shri Aurobindo Institute of Medical Sciences, Indore. The study comprised of sixty-eight anemic pulmonary tuberculosis patients. Levels of Hemoglobin, Iron, TIBC, Ferritin, MDA & TNF α were analyzed in...

A large group of bacterial virulence autotransporters including AIDA-I from diffusely adhering E. coli (DAEC) and TibA from enterotoxigenic E. coli (ETEC) require hyperglycosylation for functioning. Here we demonstrate that TibC from ETEC harbors a heptosyltransferase activity on TibA and AIDA-I, defining a large family of bacterial autotransporter heptosyltransferases (BAHTs). The crystal stru...

Serum iron may be directly measured without protein precipitation, by incubation in an acetate buffer in the presence of a reducing agent and sulfonated bathophenanthroline. Mercaptoacetic and ascorbic acids have proved to be suitable reductants. Values obtained for serum iron by this procedure show excellent correlation with a trichloroacetic acid precipitation technic. Bilirubin interference ...

A rapid procedure is described for determining total iron-binding capacity (TIBC) by use of a small, disposable resin column. Serum is saturated with excess ferric citrate, and iron not bound to protein is then removed by passing the mixture through the column of anion-exchanger. Transferrin-bound iron in the effluent, the TIBC, is determined colorimetrically (AutoAnalyzer), with 2,4,6-tripyrid...

Iron is an essential component of many important proteins and enzymes, including hemoglobin, which is responsible for carrying oxygen to the cells. African Americans (AAs) have a greater prevalence of iron deficiency compared with European Americans. We conducted genome-wide admixture-mapping and association studies for serum iron, serum ferritin, transferrin saturation (SAT) and total iron bin...

The serum iron concentration and Total Iron Binding Capacity (TIBC) status of 24 patients of oral squamous cell carcinoma (OSCC) were compared with the findings of 13 healthy subjects. OSCC was found to have association with low serum iron level. More patients were found to be with significantly lower iron content in serum (p<0.05). But no association between serum TIBC and increased risk of ca...

INTRODUCTION Oral submucous fibrosis (OSMF) is also considered as an Asian version of sideropenic dysphagia, wherein chronic iron deficiency leads to mucosal susceptibility to irritants, such as chillies and areca nut products. Hemoglobin (Hb) levels, in particular, serum iron levels, are considered as biochemical indicators for nutritional assessment. Serum iron content can thus be a predictor...

BACKGROUND Iron disorders are common and complex in chronic kidney disease (CKD). We sought to determine whether a 3-marker index would improve the classification of iron disorders in CKD anaemia. METHODS We studied the association between Hb level and iron indexes combining 2 or 3 of the following markers: serum ferritin (<40 ng/mL), transferrin saturation (TSAT<20%) and total iron binding c...
