OBJECTIVE To evaluate the relation between iron status and physical working capacity, and to assess the effect of oral iron treatment on these variables, in athletes with borderline iron status. METHODS Blood haemoglobin (Hb), packed cell volume (PCV), red blood cell count (RBC), serum iron, total iron binding capacity (TIBC), and ferritin determinations were compared in 71 male and 18 female...

CONTEXT Obesity and iron deficiency are two of the most common nutritional disorders worldwide. Several studies found higher rates of iron deficiency in obese than in normal-weight children. Hepcidin represents the main inhibitor of intestinal iron absorption, and its expression is increased in adipose tissue of obese patients. Leptin is able, in vitro, to raise hepcidin expression. OBJECTIVE...

OBJECTIVES To assess nutritional iron status and anemia prevalence in children less than 5 years old at public daycare centers in the city of Recife, PE, Brazil. METHODS A cross-sectional study, with a systematic random sampling of 162 children aged 6 to 59 months. Nutritional iron status was assessed in terms of body iron reserves (serum ferritin), transferrinemia (serum iron, total iron bin...

OBJECTIVE This study is to investigate anemia management trends in patients on peritoneal dialysis in Huashan Hospital in the past 10 years. METHODS A total of 463 cases of patients receiving peritoneal dialysis from July 2004 to March 2014 were analyzed retrospectively. The patients enrolled in this study all were elder than 18 years old, those who had been followed up for at least 1 quarter...

BACKGROUND Genetic variants of human transferrin (TF) have been described, but little is known about their functional differences. We studied iron status according to TF phenotype in a healthy Zimbabwean population and in subjects at risk of African iron overload. METHODS The study population consisted of 483 nondrinkers, 31 drinking spouse pairs, and 5 family pedigrees (n = 88) with index ca...

The ability of potential pathogens to acquire iron in a host is an important determinant of both their virulence and the nature of the infection produced. Virulent gram-negative bacteria are capable of acquiring sufficient iron from the host because their virulence (for chick embryos) is unaffected by exogenous iron. Avirulent mutants which are apparently limited in their ability to acquire iro...

OBJECTIVE Our purpose was to investigate iron status parameters in preeclampsia with a view to exploring their possible contribution to the etiology. STUDY DESIGN In prepared serum samples from 40 preeclamptic women and matched pregnant control subjects at the John Radcliffe Hospital, Oxford, a number of iron status parameters were measured. Statistical analysis was by the Wilcoxon signed ran...

We demonstrate that simple correlation between the various tests of iron status is not sufficient for examining their value in diagnosing iron deficiency (ID). Three degrees of ID are recognized: Iron depletion (ID grade I) is defined by decreased total body iron and normal iron support to erythropoiesis, as diagnosed by decreased storage iron, decreased ferritin, normal sideroblast count, norm...

1. Iron was added to hen ovotransferrin to 30% saturation and the protein was digested with trypsin or chymotrypsin. 2. Iron-binding fragments were isolated. They carried one atom of iron/mol (mol.wt. 35000) and consisted of a single polypeptide chain derived from the N-terminal half of the protein. Carbohydrate was not present. 3. The fragments were able to bind a variety of metals and to dona...

Background: The aim of the present study was to assess the mean corpuscular volume (MCV) as a surrogate marker for detecting early iron deficiency prior to definitive investigation and treatment. Materials and Methods: This study was done on one hundred students in Swada Preparatory School – Sharkia Governorate from 2010 to 2011. They were subdivided into three groups: Group (A): comprised of...
