Background Endemic goiter is present in most parts of Iran. Iron deficiency adversely affects the physiology of thyroid. The initial steps of thyroid hormone synthesis are catalyzed by thyroperoxidases and are dependent on iron. In many developing countries, children are at high risk of both goiter and iron deficiency anemia. In addition, iron deficiency may alter central nervous system contro...

CONTEXT Iron deficiency anemia in infants can cause developmental problems. However, the relationship between iron status and cognitive achievement in older children is less clear. OBJECTIVE To investigate the relationship between iron deficiency and cognitive test scores among a nationally representative sample of school-aged children and adolescents. DESIGN The National Health and Nutriti...

Hephaestin is a vertebrate multicopper ferroxidase important for the transfer of dietary iron from intestinal cells to the blood. Hephaestin is mutated in the sex-linked anemia mouse, resulting in iron deficiency. However, sex-linked anemia mice still retain some hephaestin ferroxidase activity. They survive, breed, and their anemia improves with age. To gain a better understanding of the role ...

BACKGROUND Helicobacter pylori (H. pylori) infection and iron deficiency anemia are prevalent in disadvantaged populations worldwide. The benefit of H. pylori eradiation for iron deficiency anemia has been extensively studied, but data are still equivocal. METHODS A search in The Cochrane Library, PUBMED, EMBASE, EBM Review databases, Science Citation Index Expanded, and CMB (Chinese Biomedic...

The aim of this study was to assess the prevalence of iron deficiency and iron deficiency anemia in relation to variables such as: age, weight, height, mother s education, number of family members, and nutritional habits among female elementary school children (age 6-12 years) in the western province of Saudi Arabia. A total of 123 female children were selected for this study. Complete blood co...

Understanding iron metabolism has been enhanced by identification of genes for iron deficiency mouse mutants. We characterized the genetics and iron metabolism of the severe anemia mutant hea (hereditary erythroblastic anemia), which is lethal at 5 to 7 days. The hea mutation results in reduced red blood cell number, hematocrit, and hemoglobin. The hea mice also have elevated Zn protoporphyrin ...

Autoimmune gastritis is an organ-specific autoimmune disease of the stomach associated with pernicious anemia. The previous work from us and other groups identified MCPIP1 as an essential factor controlling inflammation and immune homeostasis. MCPIP1(-/-) developed severe anemia. However, the mechanisms underlying this phenotype remain unclear. In the present study, we found that MCPIP1 deficie...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of mature red cell and reticulocyte parameters under three conditions: iron deficiency anemia, anemia of chronic disease, and anemia of chronic disease associated with absolute iron deficiency. METHODS Peripheral blood cells from 117 adult patients with anemia were classified according to iron status, and inflammatory activ...

Iron deficiency anemia is extremely common, particularly in the developing world, reaching a state of global epidemic. Iron deficiency during pregnancy is one of the leading causes of anemia in infants and young children. Many women go through the entire pregnancy without attaining the minimum required intake of iron. This review aims to determine the impact of maternal iron deficiency and iron...
