Ferric Carboxymaltose to Improve Skeletal Muscle Metabolism in Heart Failure Patients With Functional Iron Deficiency

The purpose of this study is to better understand how body levels of iron affect the ability to exercise in patients with heart failure. Heart failure is a condition in which abnormal pumping action of the heart reduces the flow of blood to the body. Patients with heart failure may feel shortness of breath or leg fatigue when they exercise. Iron is an essential nutrient in the diet. In heart failure patients, low body levels of iron might increase shortness of breath and fatigue.

Patient Blood Management In CARdiac sUrgical patientS

Nowadays up to 40% of patients undergoing cardiac surgery receives at least 1 unit of red blood cell transfusion during surgery or during the first week after surgery. Moreover up to 40% of these patients shows an absolute or relative iron deficiency, with or without anaemia. The objective of this study is to assess whether to implement an adequate correction of iron according to current "patients blood management" recommendations might reduce RBC transfusion requirements in patients undergoing heart surgery. Data obtained in patients included in the study will be compared to those of a case-control population selected from patients consecutively treated at the same department in the previous 2 years.

Preoperative Anaemia prevaLence In surgiCal patiEnts

Preoperative anaemia is common in surgery, with a prevalence between 10 and 50 %, and is an independent risk factor for morbidity and mortality. Anaemia is mostly the result of an inadequate erythropoiesis due to iron deficiency, lack of vitamin B12 or folate, and bone marrow diseases. Among the elderly, renal disease and chronic inflammation account for approximately one-third of all anaemia incidences. The aim of this study is to provide detailed data about the prevalence of preoperative deficiencies in iron, vitamin B12 and/or folate and the presence of underlying renal or chronic diseases in patients undergoing major surgery.

Improvement of Fatigue Symptoms in the Iron Deficiency Anemia With Iron Succinylate Therapy

The treatment of anemia depends on its cause. Patients with underlying iron-deficient anemia should be treated or referred to a specialist (eg gynecologist, gastroenterologist) for treatment.deficiency anemia are global health problems and common medical conditions seen in everyday clinical practice. Iron is vital for biological functions, such as breathing, energy production, DNA synthesis, and cell proliferation. Iron deficiency refers to the reduction of iron stores and precedes the occurrence of iron deficiency anemia. Iron deficiency anemia is a more severe condition in which low levels of iron are associated with anemia and the presence of small cellular red blood cells.

Iron Supplementation and Neurodevelopmental Outcome in ELGANs

This study explores the relationship between iron deficiency and neurological outcome of extremely premature infants. Premature birth occurs during a critical period of brain development and maturation, and before adequate transfer of iron across the placenta. Nutrition has a significant impact on ultimate outcome of survivors of prematurity. One of the biomarkers of nutrition in the premature infant is iron, and iron supplementation is essential for growth and brain development at low gestational age. As a result, the Committee on Nutrition of the American Academy of Pediatrics (AAP) recommends daily oral iron supplementation, of at least 2-4 mg/kg/day from 2 weeks of age, to prevent iron deficiency in extremely premature infants. Nevertheless, studies have shown that even with this regular care dose of iron, started from 2 weeks of age, a significant number of premature infants will still develop iron-deficiency. Our hypothesis states that starting high dose iron supplementation early will improve neurological development and outcome in extremely premature infants (those born at less than 28 weeks gestational age). This study will provide data showing whether individualized iron supplementation using higher doses of iron, started earlier (after the first week of life) when guided by periodic screening of their body's iron status with ferritin levels, will mitigate iron deficiency and promote improved neurodevelopmental outcome in this vulnerable infant population.

Impact of Iron Deficiency and Its Correction on Mitochondrial Metabolism of the Cardiomyocyte (MitoCardioFer)

Iron is involved in essential functions of the body. It allows the transport of oxygen in the blood, via hemoglobin, at the muscular level, via myoglobin, and it is also involved in cellular metabolism in general, in particular for the production of ATP at the mitochondrial level, within the cytochromes and iron-sulfur proteins of the respiratory chain. Recently, iron deficiency has been identified as an important prognostic factor in heart failure patients. Iron therapy improves symptoms and physical performances of heart failure patients, even in the absence of anemia. As a result, the correction of iron deficiency is now proposed as one of the therapies for heart failure. However, the pathophysiology of the association between cardiac dysfunction and iron deficiency is still poorly understood. The investigators previously developed a mouse model of iron deficiency without anemia, in which the investigators observed impaired physical performances, a decrease of left ventricular ejection fraction, and a decrease in mitochondrial complex I activity. These abnormalities were normalized after iron injection. These animal data suggest that iron deficiency is responsible for left ventricular dysfunction secondary to mitochondrial I complex abnormalities, and that iron therapy corrects them. Iron deficiency is very common in the preoperative period of cardiac surgery, affecting 40 to 50% of patients. During this surgery, it is possible to perform a myocardial biopsy without risk to the patient. The purpose of this study is to verify in patients requiring valvular heart surgery, if iron deficiency is responsible for a decrease in mitochondrial complex I activity and a decrease in cardiac function during the perioperative period, and to verify whether iron treatment improves these abnormalities.

Iron-fortified Lentils to Improve Iron (Fe) Status in Bangladesh

We designed a double-blind, community-based, cluster-randomized control trial which will test to establish novel evidence on the efficacy of iron-fortified lentil in improving body Fe status of non-pregnant adolescents in rural Mymensingh district of Bangladesh. Lentils will be fortified with iron in the lab setting at the Crop Development Center (CDC) of the University of Saskatchewan in Canada. There will be three lentils based dietary intervention arm in this efficacy trial. Arm 1 will be intervened with iron-fortified lentils, Arm 2 will be non-iron fortified lentils, and Arm 3 arm will be the usual intake of lentil (no additional lentil). Arm 2 will be served as a comparison group and arm 3 will be served as control group. A total of 420 adolescent girls (including 20% drop-outs) - aged 10 - 17y; non-smoking, not pregnant, not breastfeeding, and generally healthy will be included in each arm - a total of 1260 adolescent girls in all three arms. Participating adolescents will be served thick preparation of cooked lentils (37.5gm raw lentil) 5 days a week for 85 feeding days (around 4+months). Socio-demographic characteristics, household food security status, and adolescent food habits will be collected at baseline and endline data point. Furthermore, venous blood will be collected to measure adolescents' Fe status at baseline, midline, and endline for 85 feeding days (5 days a week)- approx. 4+ months. In addition, Ravens Progressive Matrices will be used for non-verbal measurement of the cognitive ability of advanced observation and thinking skills specific to capacity for analyzing and solving problems, abstract reasoning, and the ability to learn of the adolescents. Both descriptive and inferential statistics will be used for this study. Serum ferritin level and cognitive performance is the primary outcome. The trial expects that the supplemental Fe from the iron-fortified lentils will improve body Fe status and cognitive performance after controlling for baseline Fe status and dietary Fe intake in this group of adolescent girls. The secondary outcome is the participants' anthropometries. Considering the amount of plant protein from lentils that need to be consumed to for the study, it is expected to have significant improvement in growth of the participants which will lead to increased productivity.

Intravenous Iron Carboxymaltose, Isomaltoside and Oral Iron Sulphate for Postpartum Anemia

Anemia affects between 20 and 50 % of women in the postpartum period. It is associated with several adverse health consequences, such as impaired physical work capacity, deficits in cognitive function and mood, reduced immune function and reduced duration of breastfeeding. Postpartum anemia has also been shown to be a major risk factor for postpartum depression and to significantly disrupt maternal-infant interactions. Iron deficiency is the principal cause of anemia after delivery. Oral iron supplementation with ferrous sulfate has been considered the standard of care with blood transfusion reserved for more severe or symptomatic cases. In the last decade, two new intravenous iron compounds have been registered for clinical use: ferric carboxymaltose (Iroprem®) and iron isomaltoside (Monofer®). No study to date compared efficacy of iron carboxymaltose to iron isomaltoside for treatment of postpartum anemia. The objective of the study is to compare efficacy of intravenous iron carboxymaltose to intravenous iron isomaltoside and oral iron sulphate for treatment of postpartum anemia.
