Filter by:The overall objective of this study is to evaluate the iron absorption from iron chlorophyllin. Iron deficiency is a public health problem in both developing and industrialized countries. There are several approaches to combat iron deficiency. Most supplements in the present day, to address the problem of iron deficiency, are in the form of iron salts, known as ferrous salts, especially ferrous sulfate. However, we can only usually absorb about 20% of the total iron content in ferrous sulfate. The common strategy of food supplement companies is to increase the amount of iron in the supplements to compensate for the low absorption rate. However, this often causes gastrointestinal side effects. In the present study, we would like to measure the iron bioavailability from sodium iron chlorophyllin, which made up from ferrous salts and chlorophyllin and where we hypothesize that it is absorbed via a different pathway than ferrous sulfate. Via this mechanism, we further hypothesize that sodium iron chlorophyllin will therefore have an enhanced bioavailability and more favorable side effect profile than ferrous sulfate and other iron salts.
The target population for our study is pregnant women in the first or second trimester with a diagnosis of iron deficiency anemia. If a subject is eligible, written consent will be obtained by person to person contact. Eligible participants will be randomized to receive either daily oral iron supplementation or every other day oral iron supplementation.
Anemia is the most common extraintestinal manifestation of inflammatory bowel diseases (IBD), Although most cases of anemia in IBD are due to iron deficiency, many patients with iron deficiency anemia (IDA) are not treated with iron supplementation. In addition, it has not been firmly established which iron supplementation modality provides the best results in terms of effectiveness and safety. In the present study the investigators will compare the effectiveness and efficacy of three iron supplementation modalities in IBD-associated IDA. There will be two arms of parenteral (iv) iron supplementation (ferric carboxymaltose and ferric gluconate) and one arm of oral supplementation (sucrosomial iron). Primary objective of the study is is to compare the efficacy of oral iron with that of the iv iron supplementation regimens. The primary outcome is measured as the percentage of patients responsive to iron supplementation. Response is defined by Hb normalization or by an Hb increase ≥2 g/dL by week 8 from start of therapy. As secondary objectives the influence of anemia and its treatment on fatigue, quality of life, hospitalizations, additional outpatient visits, number of endoscopic examinations; further treatments and relative side effects will be evaluated.
Iron deficiency may play a critical role in human infertility, oocyte quality and may even play a role in endometrial receptivity. By correcting iron deficiency, low ferritin values, in infertile women with intravenous iron supplementation, embryo quality and pregnancy rates may improve. The main objective is to evaluate the effect of intravenous iron supplementation on embryo quality (number of good quality blastocysts). Randomized, double blind, parallel group, cross-over study of ferric carboxymaltose compared to placebo (NaCl infusion).
Due to the growing world population, there is a need to develop viable ecological and nutritional alternatives to animal food products. However, animal products are a key dietary source of well-absorbed iron, and iron deficiency and iron deficiency anemia remain highly prevalent in high- and low-income countries. Meat and fish provide a substantial proportion of absorbed iron in the western diet by two distinct components: a) heme iron is well absorbed (20-45% fractional absorption) and is not affected by most dietary enhancers and inhibitors, which often affect non-heme iron absorption; b) peptides in muscle meat exert an enhancing effect the absorption of non-heme iron contained in other meal components. The potential of edible insects as a dietary source of well-absorbed iron has not been investigated in detail. In particular, it is unclear whether insects provide an iron moiety similar to hemoglobin which would be well absorbed and unaffected by other dietary components, and whether their presence in a test meal exerts an enhancing effect on iron bioavailability from the whole meal. Furthermore, chitin, a major component of insect biomass, is a known iron binder and is potentially responsible for a decreased iron absorption from insect-based foods. Decreasing chitin content could allow the high amounts of iron in insects to be well-absorbed, and enhance the absorption of iron from plant-based foods. To differentiate iron absorption from insect biomass from other sources, insects will be intrinsically labelled with the stable iron isotope 57Fe, while other food iron components will be labelled with the iron isotope 58Fe.The present study will provide novel data to elucidate the nutritional value as sources of dietary iron of insect species (Tenebrio molitor). Since 2017 T.molitor is recognised as an edible insect in the Swiss food legislation and commercially available (Essento Food AG, Zürich; Insekterei, GmbH, Zürich).
The purpose of this study is to describe the prevalence of anemia and iron deficiency in pregnancy through a multi-center, prospective follow-up study . To explore the influence factors of anemia and iron deficiency in pregnancy; to explore the influence of anemia and iron deficiency in pregnancy on maternal and fetal outcomes.
INTRODUCTION: Iron is a vital nutrient for many physiological processes including DNA production, oxygen transport and neuronal processes. However, several factors limit iron absorption including: limited bioavailability of iron (dietary or supplementation sources), can be subject to dietary iron inhibitors (e.g. calcium). Excess iron can cause cellular oxidative stress in the body. Curcumin is an active component found in turmeric, known for its anti-oxidant and anti-inflammatory properties. Co-administration of iron and curcumin may influence iron, inflammatory status and/or neurotrophic markers in the body.
This study is aim to compare the efficacy of intravenous versus oral iron therapy regarding the hemoglobin levels, iron status and erythropoietin dosage in maintenance hemodialysis patients
This project is an observational controlled randomized counterbalance study. One hundred and three physically active and healthy women were selected to participate in the IronFEMME Study, of which 57 were eumenorrheic, 30 were oral contraceptive users (OCP) and 16 were postmenopausal women. The project consisted on two sections carrying out at the same time: Iron metabolism (Study I) and Muscle damage (Study II). For the study I, the exercise protocol consisted on an interval running test (8 bouts of 3 min at 85% of the maximal aerobic speed), whereas the study II protocol was based on an eccentric-based resistance exercise protocol (10 sets of 10 repetitions of plate-loaded barbell parallel back squats at 60% of their 1RM with 2 min of rest between sets). In both studies, eumenorrheic participants were evaluated at three specific moments of the menstrual cycle: Early-follicular phase, late-follicular phase and mid-luteal phase; OCP performed the trial at two moments: Withdrawal phase and active pill phase. Lastly, postmenopausal women were tested only once, since their hormonal status does not fluctuate. The three-step method was used to verify the menstrual cycle phase: calendar counting, blood analyses confirmation and urine-based ovulation kits. Blood samples were obtained to measure sexual hormones (e.g., 17β-Estradiol, Progesterone), iron metabolism parameters (e.g., Hepcidin, Iron, Ferritin, Transferrin) and muscle damage related markers (e.g., Creatine Kinase, Myoglobin, Lactate Dehydrogenase).
Anemia is a great public health problem affecting both developing and developed countries. Iron deficiency anemia represents about 50% of causes of anemia worldwide. Lactoferrin fortified milk has a positive effect on Hb and iron status of infants. the hypothesis of this study is "lactoferrin may have comparable efficacy to ferrous sulfate therapy with more tolerability and fewer side effects". the research question of this study is whether oral lactoferrin is effective for treatment of iron deficiency anemia, compared to traditional ferrous sulfate therapy regarding hemoglobin rise and side effects and tolerability.
