Objective: To gain insight into vitamin A deficiency as a cause of anemia.
Methods: Comprehensive review of the scientific literature.
Results: Although vitamin A deficiency is recognized to cause anemia, vitamin A deficiency anemia lacks complete characterization as a distinct clinical entity. Vitamin A appears to be involved in the pathogenesis of anemia through diverse biological mechanisms,
Background: Iron deficiency is assumed to be the major cause of anemia in northeast Thailand, but other factors may be involved.
Objective: We determined the prevalence of anemia among schoolchildren in northeast Thailand and the role of hemoglobinopathies, selected micronutrient deficiencies, and other factors in hemoglobin status.
Design: Blood samples were collected from 567 children aged 6–12.9 y attending 10 primary schools for the determination of a complete blood count and hemoglobin type [Hb AA (normal hemoglobin),
Background : Patients with sickle cell anemia have a higher potential for oxidative damage due to chronic redox imbalance in their red blood cells that often leads to hemolysis, endothelial injury and recurrent vaso-occlusive episodes. In this study, we evaluated plasma levels of the anti-oxidant vitamins A, C,& E and serum level of Zinc along with serum level of Copper (pro-oxidant ).
Background: Multiple micronutrient deficiencies are often the basic causative factor in stunting and anemia, 2 conditions that affect entire generations of children in deprived populations. No generally accepted recommendations for micronutrient intakes for recovery from stunting are available.
Objective: The objective was to assess the effect of a highly nutrient-dense spread fortified with vitamins and minerals,
Diets of infants across the world are commonly deficient in multiple micronutrients during the period of growth faltering and dietary transition from milk to solid foods. A randomized placebo controlled trial was carried out in Indonesia, Peru, South Africa, and Vietnam, using a common protocol to investigate whether improving status for multiple micronutrients prevented growth faltering and anemia during infancy.
OBJECTIVE: To evaluate the use of oral cyanocobalamin in the results of cobalamin (vitamin B(12))-deficient anemia.
DATA SOURCES: Primary and review articles were identified by MEDLINE search (1966-May 2000) and through secondary sources.
DATA SYNTHESIS: Cobalamin-deficient anemia is among the most common diagnoses in older populations.
Anemia is prevalent among pregnant adolescents, but few data exist on biochemical indicators of iron status in this group. We hypothesized that among an at-risk population of African-American, pregnant adolescents, the degree of iron depletion and deficiency would be marked, and that iron deficiency anemia would comprise the majority of the observed anemia. To examine this,
Vegetarian diets can be classified as either lactovegetarian, ovovegetarian, lactoovovegetarian, or vegan if they include, respectively, dairy products, eggs, both dairy products and eggs, or no animal products at all. Vegan diets have a very low cobalamin content, but a study by Herrmann et al (1) in this issue of the Journal forces us to reevaluate the shortcomings of the other forms of vegetarianism.
