Filter by:Examination of iron supplements routinely used in pregnancy to compare these with one another regarding effectiveness in the prevention of iron deficiency. Determination of ferritin / hemoglobin every pregnant woman under the first routine check. Classification into one of three subgroups (group 1: iron sulfate, Group 2: iron polymaltose, Group 3: multivitamin- multimineral) depending on the measured values. Repetition of hemoglobin every 8 weeks, at the entrance to birth and postpartum day 1, additional provision of ferritin at the entrance to birth. In addition, registration of each child's birth weight and gestational age.
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.
Iron deficiency has a high prevalence in colorectal cancer patients ranging at ca. 60%. About 70% of these patients suffer from iron deficiency anemia (IDA) which adds both physical and cognitive impediments to an already straining chemotherapy. Moreover, a chronic disease like cancer often results in a reduced availability of iron for the body. In clinical practice iron substitution is usually administered orally. Due to low resorption rates, frequent gastric side effects and thus poor patient compliance a parenteral substitution seems to be a better option in terms of efficacy. In the framework of a randomized multicenter clinical trial ('FerInject') a comparison of efficacy parameters of parenteral vs. oral iron substitution will now be conducted in order to identify the best treatment form for clinical practice in oncology. Furthermore detailed quality of life-data (QoL) will be collected in both treatment arms for effect comparison.
This is a Phase II, open-label, non-randomized, multi-center, single arm study to characterize the pharmacokinetic and pharmacodynamics (PK/PD) profile of Ferric Carboxymaltose dosing in pediatric subjects with IDA after receiving either a 7.5 mg/kg or 15 mg/kg dose of Ferric Carboxymaltose.
This study investigates the efficacy and safety of an IV iron Injectafer in the treatment of iron deficient patients with fibromyalgia. Eligible subjects will be randomized in a 1:1 ratio to receive Injectafer or Placebo on days 0 and 5. All treated subjects will be followed for efficacy and safety for 42 days.
There is a high prevalence of iron deficiency in patients who undergo bariatric surgery and effective therapies are lacking. Thus, there is a critical need for an effective, non-invasive, and inexpensive form of iron supplementation to treat iron deficiency and improve tolerance, the associated cognitive symptoms, and quality of life in the bariatric surgery patient population. Often, patients do not participate in bariatric programs, are not compliant, and/or are lost to follow-up. If there is a more effective and evidence-based guideline for repletion of iron deficiency, patients are more likely to be compliant. Therefore, in a randomized controlled study, the investigators propose to test the effectiveness of various iron formulations versus ferrous sulfate, which is the standard of care, for oral iron supplementation of iron deficient patients who have had RYGB or SG bariatric surgery. By randomizing patients into the two groups, the investigators will be able to determine the most effective regimen to improve blood biomarkers of iron status, cognitive function, and quality of life. Other outcomes will include adverse effects and compliance to the supplementation. The investigators will also analyze three-day food records to determine the contribution of dietary factors to changes in iron status. To test for improvement of iron status, serial blood draws will be performed during a time period of ~10 weeks. Serial blood draws from iron deficient patients have routinely been performed in past studies and have not been found to be harmful. Because this is a relatively short study (10 weeks), subjects will be able to recover quickly from the blood loss during the study. The investigators expect to find that iron supplementation with organic formulations of iron will be as effective than ferrous sulfate for repletion of iron deficiency, and they will be better tolerated. This project will address a significant health issue in individuals who have had bariatric surgery, which is a growing population in the United States. It is estimated that almost 1.5 million individuals have undergone bariatric surgery since the year 1990.
Recurrent upper respiratory infections ( RURTIs) are common in school aged children. An adequate iron status might reduce their prevalence. The aim of the study is to assess the percentage and type of RURTIs in Egyptian school children, assessing the percentage of iron deficiency anemia (IDA) and the effect of iron supplementation on the recurrence and severity of upper respiratory tract infections .
Iron deficiency, independent of anemia, appears to increase morbidity and mortality as well as impairing health-related quality of life in chronic heart failure (CHF), and these effects are compounded when patients also experience chronic kidney disease (CKD). This study was designed to determine the effects of intravenous iron treatment on morbidity and mortality following an initial 6-month period and a longer period of up to 5 years.
The purpose of this study is to investigate the inhibition effect of tea consumption on non haem iron absorption with the use of an iron tracer. The study also aims to assess the effect of time variability of tea consumption on non haem iron absorption from a typical western breakfast.
