Filter by:Iron deficiency anemia is a very common problem accompanying pregnancy. in this study, the investigators are going to compare the efficacy and tolerability of two preparations of oral iron in treatment of iron deficiency anemia with pregnancy.
Previous studies on iron absorption have focused on the effects on the addition of iron absorption enhancers like ascorbic acid and EDTA to a meal and more recently the enzymatic phytic acid removal through phytase. The investigators want here to investigate the effects of fat on iron absorption with and without the addition of exogenous phytase as a potential iron absorption enhancer in lipid nutrient supplements (LNS) products compared to micronutrient powder(MNP) products. Furthermore the investigators will evaluate the effects of Lipids- on iron absorption to induce the ileal brake by ingestion of a fat emulsion prior to a meal. Increasing the caloric density of a meal by increasing its fat content might enhance iron absorption by delaying gastric emptying, gastric acid secretion and increasing Fe stomach residence time.
Iron deficiency is the most common micronutrient deficiency in the world today, affecting more than 60% of the global population (www.who.int/nut/ida.htm). The two main strategies for the prevention and treatment of iron deficiency involve fortification of food with iron, or direct supplementation with iron tablets. Simple iron salts (e.g. ferrous sulphate) are well absorbed but at supplemental levels (and potentially at lower levels, as used in food fortificants) can induce free radical activity resulting in gastrointestinal side effects and systematic oxidative stress. As a result, supplementation has poor compliance and improvement in iron status is compromised. Ferric salts are less inclined to produce side effects and although they are relatively well absorbed at fortification levels in food, they are poorly absorbed at the higher supplemental doses. Because certain components of food, such as organic acids, can facilitate ferric iron absorption, we now wish to determine whether dietary organic acids may similarly enable efficient absorption of supplemental ferric iron while preventing the formation of non-transferrin-bound iron (NTBI) which is a proxy for free radical activity. Our strategy is to use an iterative process between in vitro and in vivo experimentation, aimed at identifying the best choice of organic acid and the optimal ratio of iron:organic acid. The study was a cross-over, single-dose comparison against standard-of-care therapy (namely ferrous sulphate) in mildly iron deficient anaemic women. Both the investigational products and the active comparator were administered as a single dose on 2 different occasions, i.e. the investigational products on the first study visit and the active comparator 14 days later on the second study visit.
Iron deficiency anaemia is common in inflammatory bowel disease (IBD), affecting at least 20% patients at any one time. Hepcidin, a recently described anti-microbial peptide synthesized by the liver, is a key regulator of iron homeostasis. It interferes with absorption of iron into enterocytes, macrophages and hepatocytes by binding to ferroportin. Hepcidin levels rise when total body iron levels rise and protect against iron overload; conversely, in iron deficiency, levels are low. Hepcidin levels also rise under the influence of interleukins (IL)-6 and -1, a factor likely to contribute to iron deficient erythropoesis in active IBD. Whether hepcidin levels predict resistance to oral iron therapy in IBD is unknown, though it may impair its immediate oral absorption. Adult IBD patients who are anaemic report quality of life and fatigue scores comparable to those seen in malignancy. IBD diagnosed in adolescence interferes with growth, education and employment as well as psychosocial and sexual development. Not surprisingly, adolescents with IBD have a high prevalence of psychological distress, particular depression. Limited historical, and our own data suggest that children and adolescents with IBD are more anaemic than adults, and less often treated with oral iron. What is not clear is whether the apparent under-utilisation of oral iron in paediatric care is because of a perceived lack of benefit or doctors' concerns about possible side effects including worsening disease activity. To address these questions, the investigators propose a comparative study of 6 weeks of oral iron supplementation in adolescents and adults with iron deficiency anaemia in IBD. Patients will be given oral iron supplementation. Before and after iron therapy, the investigators shall assess haemoglobin concentrations; IBD activity; quality of life (QOL), perceived stress, mood and fatigue; iron metabolism, including serum hepcidin.
Slow release iron capsules containing ferrous sulfate 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.
The primary objective of this study is to compare the total costs to sites and payers of administering IV iron over the 30-day observation period for subjects with IDA who receive Ferric Carboxymaltose (FCM) relative to those who receive iron sucrose, iron dextran, and ferumoxytol.
The purpose of this study is to investigate the efficacy of ferumoxytol for the repletion of iron stores and correction of iron deficiency anaemia in patients with severe chronic kidney disease or end-stage chronic kidney disease on peritoneal dialysis, and to assess the impact of the administration of a ferumoxytol dose on various markers for iron stores, as well as on various markers for inflammation and oxidative stress.
Intravenous iron replacement has been shown to benefit patients with heart failure and iron deficiency, but the weekly outpatient regimens studied to date are impractical for many patients. Our purpose is to evaluate the short-term effects and safety of an accelerated intravenous iron regimen in hospitalized patients with these two conditions.
Heart failure (HF) is a major global public health issue which also affects Asia. Data from the National Registry of Disease in Singapore shows a 9.4% rise in HF admissions in public hospitals from 2008 to 2009 (4140 to 4530). Anaemia (low blood Haemoglobin level) is a common problem occurring in HF, ranging from 14% to 56% in outpatient registries and clinical trials. Anaemia exacerbates the basic symptoms of HF of dyspnea and exercise intolerance, thereby reducing quality of life (QoL). However, recent approaches aimed at improving and normalizing Haemoglobin have been unsuccessful.Novel approaches are required to address this problem. Iron deficiency (ID) is a well-understood cause of anaemia. ID without overt anaemia may be present in HF patients. A recent study by Jankowska et al published in 2010 of 546 HF patients showed a 37% prevalence of ID, regardless of Haemoglobin level. This was associated with worse outcomes including impaired exercise capacity. The presence of ID indicates a higher likelihood of deteriorating and dying early. A landmark study published in the New England Journal of Medicine (The Ferinject Assessment in Patients with Iron Deficiency and Chronic Heart Failure (FAIR-HF) study) showed that HF patients who were treated with IV iron in the form of Ferric Carboxymaltose (FCM) had better outcomes, including improved exercise capacity, overall function, and quality of life. There is a lack of contemporary data on ID in HF patients in Asia, including data on treatment with this novel IV iron FCM. Hypothesis We hypothesise that treating ID in HF patients in Asia using FCM will improve outcomes including exercise capacity, quality of life, overall functional status, and the need to be hospitalised for complications arising from HF.
This study is a randomized, controlled, double-blinded single center trial to compare the efficacy of NovaFerrum® to ferrous sulfate for the treatment of nutritional iron deficiency anemia (IDA) in infants and young children. Hypothesis: NovaFerrum® has greater efficacy than ferrous sulfate in increasing hemoglobin concentration during a twelve week course of treatment to subjects with iron deficiency anemia. Primary Aim: To compare the efficacy of NovaFerrum® to ferrous sulfate for the treatment of nutritional IDA in infants and young children as determined by increase in hemoglobin concentration. Secondary Aims: 1. To compare the adverse effects of treatment for IDA between ferrous sulfate and NovaFerrum® 2. To compare normalization of iron stores as demonstrated by laboratory measures of IDA (ferritin, TIBC, reticulocyte hemoglobin content) between subjects treated with ferrous sulfate or NovaFerrum® 3. To compare the adherence to study medication between subjects on ferrous sulfate and NovaFerrum® 4. To demonstrate efficacy of a once daily dosing regimen in the treatment of nutritional IDA
