Filter by:Slow release iron capsules have been designed based on the gastric delivery system. Iron absorption from those capsules administered with and without meals will be measured using stable iron isotopes.
This is a pilot study designed to compare the tolerance of ionic iron (ferrous sulphate) with heme iron polypeptide. Subjects will take one week of one product followed by a week with no product followed by a week with the other product. Subjects will complete a daily diary to assess side effects. Hypothesis: Heme iron polypeptide is associated with fewer gastrointestinal side effects than ionic iron.
Anemia is a common complication in patients with chronic kidney disease (CKD). In addition to erythropoietin deficiency, many studies have identified iron deficiency as a cause of anemia in CKD patients. Most patients with CKD are iron deficient because of: inadequate intake and absorption, gastroenteric bleeding, urinary iron loss in patient with significant proteinuria. The iron treatment is pivotal to manage anemic patients with CKD: the prescription of iron is usually oral because of practicality and safety, but often it is inevitable to administer intravenous iron because of gastroenteric malabsorption, intolerance to oral administration, irregular intake. There're few randomized controlled studies about the efficacy of oral iron versus intravenous iron in patients not on dialysis; most of them demonstrate superiority of intravenous therapy to restore iron deficiency and hemoglobin levels. A particular formulation of iron, liposomal iron has a high gastroenteric absorption and high bioavailability with lower incidence of side effects. The investigators study aims to evaluate the efficacy of treatment with liposomal oral iron compared to intravenous iron in CKD anemic patients not on dialysis in the presence of iron deficiency.
The purpose of this study is to determine whether intravenous or oral iron are effective in the treatment of postoperative anemia and iron deficiency in patients submitted in postbariatric abdominoplasty.
On exposure to hypoxia (low oxygen) the normal response is for pulmonary arterial systolic blood pressure (PASP, blood pressure through the lungs) to increase. We have previously shown that raising iron by giving an infusion of iron into a vein reduces this pressure rise and that lowering iron by giving a drug that binds iron, magnifies this response. This is potentially a clinically important observation since iron-deficient people may be at increased risk of pulmonary hypertension if exposed transiently or permanently to hypoxia due to lung disease or residence at high altitude; furthermore if this were true then intravenous iron could be an important treatment in this patient group in the event of hypoxic exposure. The observed effects of iron on PASP are likely to be because iron levels affect oxygen sensing. Low iron levels make the body behave as if exposed to low oxygen by inhibiting the breakdown of the family of oxygen-sensing transcription factors, 'hypoxia inducible factor' or HIF. This includes one of the body's normal responses to low oxygen levels - raising blood pressure through the lungs. This study will answer the question (1) do iron-deficient volunteers have a greater rise in PASP with hypoxia than those who are iron-replete, and (2) does giving intravenous iron cause a greater reduction in the rise in PASP in those who are iron-deficient than iron-replete? The purpose of this study is not to test the safety or clinical efficacy of iron which is already known.
Problematic and state of the art Obesity and its associated non communicable diseases (NCDs) are rising rapidly in middle income countries, such as those in the Maghreb (North Africa). This progression is related to the context of a nutrition transition (changing food and physical activity environment) and profound changes in technological advances and in society. These societies and their health systems are insufficiently prepared for this evolution, which has enormous health and socioeconomic consequences. In the context of limited resources, the priority has been given on an international level to prevention. But several problems arise: - these countries are still confronted by undernutrition in terms of micronutrient deficiencies, which coexist with obesity and NCDs, including at a family level and also individual level. Known as the 'double burden', this coexistence is relatively new and has been rarely documented until recently. Educational measures could be ineffective in a society where cultural norms do not recognise obesity and where changes in lifestyle are possibly not seen as acceptable. As well as information about citizen's knowledge of risk factors, data on their perceptions and attitudes are indispensable. Policies that involve changing the 'obesogenic' environment that individuals occupy is a priority. Objectives of the project Overall aim: to contribute to the development of preventive strategies for obesity and chronic NCDs in the context of a nutrition transition. Specific objectives: characterise the nature and size of the double burden (obesity/undernutrition) in regions, families and individuals; estimate the prevalence of biological and behavioural risk factors; characterise the psycho-sociocultural determinants of behaviour.
This study is initiated to investigate the effect of multi micronutrient supplementation for 12 months on serum haemoglobin level in Indonesian young children.
The hypothesis to be tested is whether treatment with intravenous iron (ferric carboxymaltose) will improve left-ventricular ejection fraction in patients with heart failure and iron deficiency as determined by cardiac magnetic resonance imaging.
Extra iron may not be necessary in the treatment of iron deficiency anemia in Crohn's Disease;Oxidative Stress and Inflammation may be Caused by Intravenous Iron in Crohn's Disease Patients With Iron Deficiency Anemia.
2-3% of the population participates in blood donation programmes. Traditionally, safety issues in transfusion medicine have been concentrating on product and recipient safety. Extensive efforts including strict donor inclusion criteria and testing for important transmissible infections have substantially improved product quality. One of the most common risks of blood donation is iatrogenic iron deficiency. It may affect up to 30% of regular blood donors because each whole blood donation causes a loss of 200 to 250 mg of iron. Although this has been known for at least 50 years, iron deficiency is not routinely assessed or treated in this population. Contributing factors include donation frequency, lower weight and female gender. Women have lower iron reserves and in premenopausal women, the daily required amount of iron is higher than in men. Besides anemia, iron deficiency may lead to fatigue and impaired cognitive and physical performance. Oral iron substitution is often associated with significant gastrointestinal side effects leading to poor compliance. Today, intravenous (iv.) iron preparations are well tolerated and allow the application of a large dose of 1000mg in one visit. Our hypothesis is that in blood donors with iron deficiency intravenous iron is feasible and preferable to oral iron because of its high efficacy and optimal compliance with a similar safety profile that has been extensively studied in other populations than blood donors.
