Filter by:Iron deficiency anemia during pregnancy is a significant worldwide health problem, affecting 22% of pregnant women in industrialized countries and 52% in non-industrialized countries. Iron deficiency anemia during pregnancy is associated with increased maternal as well as fetal morbidity, including prematurity, low birth-weight and perinatal and infant loss. Therefore, routine iron supplementation during the second half of pregnancy has been recommended once daily. Others, however, support a selective iron supplementation only for women with iron deficiency anemia, in order to avoid the increased risk of haemoconcentration associated with routine iron supplementation. Unfortunately, compliance to either iron-supplementation programs, especially among pregnant women, is poor, due in part to the side effects associated with these preparations. Currently, there are many iron preparations available containing different types of iron salts, including ferrous sulfate, ferrous fumarate, ferrous ascorbate but common adverse drug reactions found with these preparations are mainly gastrointestinal intolerance like nausea, vomiting, constipation, diarrhea, abdominal pain, while ferrous bis-glycinate (fully reacted chelated amino acid form of iron) rarely make complication. Product resulting from the reaction of a metal ion from a soluble salt with amino acids to form coordinate covalent bonds, the resulting molecule is called as chelate and chemical bonding process is called chelation. Ferrous bis-glycinate is highly stable and totally nutritionally functional chelate it is an amino acid fully reacted chelate which is formed by the binding of two molecules of glycine to one Fe2+ atom.
The investigators studies will compare iron, respectively iron and zinc bioavailability from fortified rice produced from different fortification techniques using stable isotopic labels. Study 1 aims to compare the iron bioavailability from hot and cold extruded rice, in Study 2 the iron and zinc bioavailability from rice using one coating technique and hot extrusion will be compared.
The study will assess the safety, tolerability and efficacy of CSJ137 in chronic hemodialysis patients. It is hypothesized that treatment with CSJ137 may improve the level of hemoglobin in patients on chronic hemodialysis with iron-restricted anemia while reducing the need for dosing with erythropoietin and intravenous iron in these patients.
The objective is to monitor and quality assure the efficacy, including effects on quality of life, and safety of Monofer® in Chronic Kidney Disease and Inflammatory Bowel Disease patient populations when Monofer® is used according to the Monofer® label (Summary of Product Characteristics, SPC) in current clinical practice and where standard routines are being followed.
This study evaluates auditory neural maturation by auditory brainstem evoked response in late preterm and term infants with in utero iron deficiency compared with neonates with normal in utero iron status.
The purpose of the study is to determine the relative effect size of standard IV and oral iron treatment of RLS with Iron deficiency anemia (IDA) and to determine the time course of treatment response.
At MRC Human Nutrition Research, the investigators have developed an engineered analogue of the ferritin-core for safe and effective iron supplementation. Iron hydroxide adipate tartrate (IHAT) is a tartrate-modified, nano-disperse Fe(III) oxo-hydroxide, formed in an adipate buffer, with similar functional properties and small primary particle size (~2 nm) as the iron found in the ferritin core; it better mimics iron absorption from food than the non-physiological bolus doses of ferrous sulphate currently used. This exploratory study will test the hypothesis that IHAT has equivalent bioavailability to ferrous sulphate but produces a less harmful post-ingestion rise in transferrin saturation. The design is a 3-arm (IDA, non-IDA and IDA-IHAT new manufacture), crossover, randomised, single-dose study. Primary endpoint: Relative bioavailability value of IHAT versus ferrous sulphate. This will be determined from the red blood cell incorporation of isotope-labelled iron 14 days following a single oral dose. Secondary endpoints: Serum iron at 0, 2, 4, 6 hours following a single dose of each iron compound. Transferrin saturation at 0, 2, 4, 6 hours following a single dose of each iron compound. Plasma 58Fe and 57Fe at 0, 2, 4, 6 hours. Pathogen growth using ex vivo assays in serum collected from each subject at 0, 2, 4 and 6 hours following a single dose.
It is the investigators hypothesis that participants treated with Ferric Citrate (FC) during the non-dialysis CKD stage (4/5) with sufficient duration prior to initiating RRT, will result in improved biochemical control of anemia (Hb, TSAT) and mineral metabolism (P, FGF23) and furthermore, will result in a reduced need for ESA and intravenous iron. The investigators further hypothesize that effective treatment of anemia and mineral metabolism with FC in the pre-dialysis and transition period will result in improved physical functioning, reduced hospitalization and reduced total cost of care when compared to participants receiving contemporaneously provided standard of care therapy.
ID in children is the most frequent micronutrient deficiency in industrialized countries, including France. ID induces neurological impairment reducing cognitive, motor, and behavioral capacities in children in the short and long term. The purpose of this study is to evaluate the principal determinants of ID in France in two-year-old children and to improve strategies for prevention and screening. The main objective is to study the association between iron status in two-year-old infants living in France and the consumption of toddler milk formula after taking non-dairy iron ingestion, parental socioeconomic status and educational level into account. The secondary objectives are the following : - to estimate the prevalence of ID and ID anemia in 2-year-old children living in France. - to improve clinical tools for ID screening. to improve strategies for laboratory screening.
Globally, the most common cause of anemia is thought to be iron deficiency anemia (IDA). This was assumed to be the major cause of anemia in Cambodia, because Cambodian diets, which consist mainly of rice, lack iron-rich animal food sources. However, our findings from a previous study in Cambodia (a Canadian government funded study investigating multiple interventions to improve food and nutrition security) showed that IDA is almost non-existent and challenges this assumption. In a cross-sectional survey of 450 women from rural Cambodia, only 1.0% had Hb and ferritin levels indicative of IDA (Hb <120 g/L and ferritin <15 μg/L). A national survey conducted by UNICEF in 2014 found similarly low rates of IDA (Dr. Arnaud Laillou, UNICEF Cambodia). Further, other micronutrients known to be associated with anemia were also low (<3%) including folate and vitamins B12 and B6. In addition, 54% of the Prey Veng women had a genetic Hb disorder (e.g., α-thalassemias), which are inherited diseases that can result in a defective Hb structure and/or impair Hb production, either of which can reduce Hb concentration and increase the risk of anemia. Further, genetic Hb disorders cause ferritin and soluble transferrin receptor (sTfR) concentrations to increase, which reduce the diagnostic sensitivity of these biomarkers to identify IDA. In 2011, the Cambodian Ministry of Health (MOH) recommended weekly iron and folic acid (IFA) supplementation for all women of reproductive age, consistent with WHO guidelines. However, if iron deficiency is not a major cause of anemia, then at best supplementation is a waste of valuable resources and at worst could cause harm. Further, the justification for provision of multiple micronutrients among this population has not yet been proven, despite the push from some organizations such as the WHO. There is an urgent need to conduct a trial to clarify whether iron or other micronutrient deficiencies are a major cause of anemia in Cambodia. Research Objectives: 1. To compare Hb concentration (g/L) after 12-weeks of supplementation in women to determine if iron significantly improves Hb concentration, compared to a placebo; 2. To compare Hb concentration (g/L) across the four groups (multiple micronutrients with iron, multiple micronutrients without iron, iron alone, and placebo) after 12-weeks; and 3. To determine which of the hematological indicators (ferritin, sTfR, reticulocyte count and hepcidin) have the strongest diagnostic ability to predict responsiveness to iron therapy after 12-weeks using receiver operating characteristic (ROC) analyses. Methods: A 2 x 2 factorial randomized controlled trial will be conducted over 12 weeks. A total of ~800 women (18-45 y) with mild or moderate anemia will be recruited and randomized to 1 of 4 groups: multiple micronutrients with iron, multiple micronutrients without iron, iron alone or placebo. Blood will be collected at baseline and at 1 and 12 weeks after the intervention and assessed for Hb, hematological biomarkers, inflammation and genetic Hb disorders. The investigators will use a general linear model to measure differences in Hb concentration across the four groups after the intervention. Receiver operating characteristic curves will be used to determine the diagnostic ability of the multiple hematological indicators to predict responsiveness to iron therapy.
