OBJECTIVES To identify the prevalence of iron deficiency in the population studied, as well as verifying if such deprivation is associated with vitamin A deficiency. METHODS One hundred seventy-nine children, > or = 24 months and < 72 months of age, with no diarrhea and/or fever at collection were studied. Vitamin A deficiency identification was carried out through serum 30-day dose-response ...

introduction: iron deficiency anemia is an important limiting factor for the number of donations in regular donors. limited data is available on the iron status in iranian donors. this study was conduced to evaluate the prevalence of iron deficiency and its related factors in blood donors at shiraz blood transfusion centre in 2005. methods: this descriptive study was done on all blood donors wh...

Background: This study was done to highlight the magnitude of iron deficiency anemia in Bahawalpur, a big city of Southern Punjab Region of Pakistan, so that affective remedies are carried out to address iron deficiency among vulnerable groups in this part of Pakistan. There have been no such study has been conducted to assess the prevalent type of anemia in Bahawalpur region in past. Method: O...

Vitamin A deficiency produces anemia and altered iron status. In this study with rats we tested two hypotheses regarding vitamin A deficiency: (1) that it impairs erythropoiesis, leading to an increased red cell turnover, and (2) that it inhibits the glycosylation of transferrin. Erythropoietic activity was assessed indirectly by determining the myeloid:erythroid ratio in bone marrow smears, th...

Objective: We posited a trade-off in iron nutrition, with iron deficiency decreasing risk for infection by depriving infectious agents of iron while increasing risk for infection by compromising immune protection. We described associations between iron deficiency and prevalent and incident infectious disease episodes and cell-mediated immunity (CMI) among 283 children in Kilimanjaro, Tanzania. ...

Rice plants (Oryza sativa L.) utilize the iron chelators known as mugineic acid family phytosiderophores (MAs) to acquire iron from the rhizosphere. Synthesis of MAs and uptake of MA-chelated iron are strongly induced under conditions of iron deficiency. Microarray analysis was used to characterize the expression profile of rice in response to iron deficiency at the genomic level. mRNA extracte...

BACKGROUND Diagnosis and treatment of iron deficiency anemia in older subjects improves their quality of life. Serum ferritin as a marker of iron stores is an acute phase protein. In older subjects who usually have many concomitant chronic medical conditions, serum ferritin may increase in response to inflammatory processes irrespective of iron stores. This study was performed to determine the ...

Anemia is a very common condition in patients with gastrointestinal tumors, with a negative impact on mortality, morbidity and quality of life. The underlying causes are blood loss, chemotherapyinduced myelosuppression and iron deficiency. Yet, anemia and more specifically iron deficiency remains undertreated in daily clinical practice, mainly because many clinicians are not familiar with using...
