A 9-month randomized, double-blind, placebo-controlled study to compare the effect of fixed dose ferric citrate versus placebo in patients with advanced chronic kidney disease (eGFR ≤20 ml/min/1.73m2) on the composite endpoint of time to initiation of maintenance dialysis or all-cause mortality.

Prebiotic GOS and Lactoferrin With Iron Supplements

Iron-deficiency

The ultimate goal of this research is to develop a means to safely administer iron supplements to infants in settings with a high infection burden. The investigators will conduct a randomized clinical trial in 6 month-old Kenyan infants in conjunction with mechanistic microbiota studies using a novel long-term continuous polyfermenter platform inoculated with immobilized fecal microbiota from Kenyan infants. Oral iron supplements are associated with a significant 15% increase in the rate of diarrhea in children in malaria-endemic areas. The most recent studies have shown that prebiotic galacto-oligosaccharides (GOS) can provide partial amelioration of the adverse effects of iron supplementation by enhancing the growth of barrier populations of bifidobacteria and lactobacilli. The investigators hypothesize that the combination of GOS with bovine lactoferrin, adding iron sequestration as well as antimicrobial and immunomodulatory activities, will provide almost complete protection against the adverse effects of added iron on the intestinal microbiota.

Potential Harms of Untargeted Iron Supplementation in Cambodia Where Iron Deficiency is Not the...

AnemiaIron Deficiency4 more

In 2016, the World Health Organization (WHO) set a global policy recommending daily oral iron supplementation (60 mg iron) for 12 weeks for all women living in countries where anemia prevalence is >40%, such as in Cambodia. However, recent studies have shown the prevalence of iron deficiency to be low in Cambodian women and that supplementation would likely only benefit ~10% of women. Iron supplementation may be harmful in women with genetic blood disorders (e.g. thalassemia), which are common in Cambodia, as these individuals are already at an increased risk of iron overload. The risks are made greater by the fact that iron absorption from most common form of supplementation, ferrous sulfate, is low. Typically less than 20% is absorbed in the gut; the remaining 80% passes unabsorbed into the colon where it can increase the risk of pathogen growth and gut inflammation. Alternatively, ferrous bisglycinate is a newer supplemental form of iron. This amino acid chelate has 2-4x higher bioavailability than ferrous sulfate and is associated with fewer GI side-effects. In view of WHO policy and risks of supplementation, there is a need to determine the potential for harm, and if novel forms of iron supplements are safer.

Oral Iron Supplementation for Patients With Chronic Kidney Disease

The hypothesis of this research is that oral iron prescribed in a single dose in alternate day could mitigate the side effects with regard to intestinal microbiota, inflammation, oxidative stress and improve the hematological profile when compared to daily oral iron prescription

Effects of Intravenous Administered Iron in Non-anemic Iron Deficient Patients With Colorectal Cancer...

Iron-deficiencyColorectal Cancer

This double-blinded clinical randomized trial with a 1:1 recruitment ratio between placebo and the active group will aim to investigate the effects of intravenously administered iron in non-anemic iron deficient patients on physical capacity, immunological cells and their function prior to surgery. A total of 134 patients with colorectalcancer will be included in the study. Study outline: After initial inclusion the patient will undergo baseline testing with cardiopulmonary exercise test (CPET), then followed by an infusion of a weight dependent dosage of iron(III)isomaltoside or placebo. Then at the closest possible time to the surgery the patient will have drawn bloodwork and be re-tested by (CPET). The patient will be followed after surgery with evaluation of several outcomes including quality of recovery and complications. Further, the effects of the intervention on the patients immune function will be evaluated by two different methods: 1) by changes in neutrophil-to-lymphocyte ratio between baseline and preoperative bloodwork and 2) by evaluation mRNA expression in the tumor specimen by the Nanostring pancancer immune panel

Effects of Enhancers and Inhibitors on Absorption From Iron Supplements

Iron-deficiencyIron Deficiency Anemia

Iron deficiency (ID) is a major public health problem worldwide and oral iron supplementation can be an effective strategy to treat and prevent ID. To maximize iron bioavailability form oral iron supplements the simultaneous intake of the iron absorption enhancer ascorbic acid (AA) is recommended, and the simultaneous intake of coffee or tea containing the iron absorption inhibitors polyphenols should be avoided. Also, oral iron supplements are recommended to be taken on an empty stomach in the morning and without a meal to avoid any interaction with phytic acid, another iron absorption inhibitor present in many foods. However, the effects of these iron absorption enhancers and inhibitors have only been shown on iron absorption from dietary iron (up to 10mg). Also, the effect of the diurnal hepcidin increase on absorption from an iron supplement given in the afternoon without a preceding morning dose is unclear. Whether AA also increases iron bioavailability from a supplemental iron dose and whether a cup of coffee, a breakfast or iron administration in the afternoon decreases iron bioavailability from a supplemental dose is uncertain.

Neuroimaging Ancillary Study

Iron Deficiency AnemiaIron Deficiency Anemia of Pregnancy4 more

As a follow-up to the RAPIDIRON Trial (NCT05358509), and in combination with the RAPIDIRON-KIDS Study (NCT05504863), this study will involve infants of RAPIDIRON Trial participants recruited at one site in Karnataka and is designed to implement a magnetic resonance imaging (MRI) protocol and incorporate neuroimaging measures. Implementation of this study will promote an understanding of the effects on fetal and neonatal brain development, including iron deposition in brain tissues, when a woman is treated for iron deficiency anemia (IDA) by either (a) providing her oral iron tablets and instructions for use; or (b) administering a single-dose IV iron infusion for the treatment of IDA during pregnancy.

Iron Deficiency AnemiaNeurodevelopmental Abnormality1 more

As a follow-up to the RAPIDIRON Trial (NCT05358509), this study will follow the previously randomized mothers as well as their offspring after birth to assess neurodevelopmental, hematologic, and health outcomes. The study's overarching goal is to determine if the offspring born to RAPIDIRON Trial mothers in the intravenous iron groups, compared to the oral iron group, will achieve superior neurodevelopment, iron stores, and growth at specific time points during the first three years of life. Differences will be assessed between offspring based on the iron deficiency anemia (IDA) treatment of the mother.

Ferric Derisomaltose and Outcomes in the Recovery of Gynecologic Oncology: ERAS (Enhanced Recovery...

Gynecologic CancerAnemia1 more

Iron deficiency has been reported in approximately 35% of patients with a gynecologic malignancy. Blood transfusions are known to be immunosuppressive and carry immediate and long-term risks. Pre-operative blood transfusion in gynecologic oncology patients is associated with higher rates of surgical site infection, length of stay, composite morbidity, cancer recurrence, and mortality. Pre-operative intravenous iron formulations have been shown in benign gynecology and other surgical specialities to increase pre-operative hemoglobin and decrease post-operative transfusion rates. This is a randomized double-blinded clinical trial evaluating the effects of treating patients undergoing gynecologic oncology surgery with intravenous ferric derisomaltose to correct pre-operative iron-deficiency anemia. The study aims to assess the effectiveness of preoperative ferric derisomaltose/iron isomaltoside compared to placebo in correcting preoperative hemoglobin in patients undergoing surgery for gynecologic malignancy.
