Filter by:Background: Iron deficiency in early childhood may impair neurodevelopment. Aim: To examine whether early iron supplementation improved neurodevelopment in preterm infants. Method: Children who participated in a clinical trial of iron supplementation were invited for a neurodevelopmental follow-up examination at the time of school entry.
Infants should receive prophylacatic iron supplementation since age 4 months till one year. Patients suffering from malabsorption, mainly Giardia infestation may develop iron deficiency resistent to further iron treatment. The purpose of this study is to assess the incidence of malabsorption in those infants and to examine the results of empiric treatment with metronidazole.
The purpose of this study is to determine the extend and the nature of anemia in school children and the correlation between anemia and schistosomiasis infections, malaria infections and/or malnutrition (iron deficiency).
The objective of the study is to develop a simple, noninvasive test for evaluation of iron absorption as a tool to determine the cause of iron deficiency anemia. Healthy, premenopausal women with iron deficiency with or without anemia will be recruited for the study. Participants will, over the course of two months, ingest an iron solution three times; after each iron ingestion, participants will collect their stool and bring it to the study investigators for assessment of iron content.
The aim of this study is to evaluate the effect of muscular exercise on iron metabolism in healthy volunteers. Fourteen healthy male subjects will have to pedal on an ergocycle for 45 minutes, and urine and blood samples will be collected regularly to measure hemojuvelin, hepcidin, iron and transferrin levels.
The investigators hypothesize that the Helicobacter pylori bacterium decreases iron from the stomach and that this effect of the infection can be identified among persons with iron deficiency as well as among persons with normal iron stores. The aim of this study is to determine whether Helicobacter pylori eradication in children is followed by an increase in markers of iron stores after six to twelve months of treatment.
This pilot study will compare the effects of sodium ferric gluconate complex and iron sucrose on urine concentrations of various chemicals including protein
Blood donors who have a low fingerstick hemoglobin level are usually deferred from donating. A possible solution to the problem of repeated deferrals might be for Blood Banks to offer donors with low hemoglobin levels oral iron supplements. To determine the feasibility of such a program, this study will: - Determine the frequency of iron deficiency in first-time and repeat blood donors - Examine the effects of long-term blood donation on donor hemoglobin levels and iron stores - Compare body iron stores in donors who have low hemoglobin values with that of donors who have acceptable hemoglobin values at the time of donation - Determine what conditions other than iron deficiency lead to low hemoglobin levels in blood donors - Determine the safety and effectiveness of giving oral iron tablets to donors with low hemoglobin levels - Monitor the effect of oral iron administration on donor satisfaction and donor retention. First-time and repeat blood donors at the NIH Clinical Center Blood Bank 18 years of age and older may be eligible for this study. Participants include prospective donors who have an acceptable hemoglobin value at the time of donation and those whose hemoglobin level is determined to be too low for donation. All participants do the following: - Answer medical questions about their diet, health, and family history of blood disorders. - Have blood samples drawn from their arm for testing blood cell counts, iron stores, and other hemoglobin-related tests as appropriate. Donors with low hemoglobin also: - Take iron supplements (ferrous sulfate) to replenish iron stores. (Donors who have previously had unpleasant side effects from ferrous sulfate are offered ferrous gluconate as an alternative.) - Undergo evaluation with medical screening and laboratory tests at the time of future blood donations.
The purpose of this study is to determine if oral Heme Iron Polypeptide is as effective as intravenous (IV) iron sucrose in the treatment of iron-deficiency anemia for patients with chronic kidney disease.
The purpose of this study is to determine whether the frequency of intravenous iron administration has an effect on anemia correction and oxidative stress formation in hemodialysis patients.
