View clinical trials related to Anemia, Iron Deficiency.
Filter by:Iron deficiency (ID) anaemia (IDA) is a global public health problem, with the highest prevalence in Africa and in South-East Asia. While immunization programs have achieved high global coverage, vaccines often underperform in low- and middle-income countries (LMIC). The cause remains uncertain, but undernutrition, including ID, likely plays a role. Our recent in vitro and in vivo studies have shown the importance of iron status in adaptive immunity and vaccine response. Hypoferremia blunted T cell, B cell, and neutralizing antibody responses to influenza virus infection in mice, allowing the virus to persist. Iron deficient anaemic Kenyan women receiving intravenous iron at time of vaccination had a better immune response to the first dose of the ChAdOx Coronavirus 19 (COVID-19) vaccine and yellow fever vaccine. Japanese encephalitis and typhoid fever are endemic in Thailand. Vaccines are available but show variable efficacy. Whether ID impairs adult vaccine response to the live attenuated Japanese encephalitis (JE) and the Typhoid Vi polysaccharide (Vi-PS) vaccine and whether iron repletion via iron fortification improves vaccine response is uncertain. The objective of this study is to assess whether IDA in Thai women impairs immune response to the JE and the Typhoid Vi-PS vaccine and whether fortification iron improves their response. In this double-blind randomized controlled trial, IDA women will be assigned to two study groups: group 1 (fortification group) will receive iron-fortified biscuits (15mg iron as ferrous fumarate) for 56 days; group 2 (control group) will receive non-fortified biscuits for 56 days. All women will receive live attenuated JE and Typhoid Vi-PS vaccine on study day 28. Vaccine response will be measured 28 days after vaccination (on day 56) in both groups.
Previous studies have shown that perioperative intravenous iron has a beneficial effect on patients with perioperative anaemia. To assess whether a combined iron supplementation regimen can reduce perioperative allogeneic blood transfusions in patients with iron deficiency anaemia undergoing major cardiac surgery under haemodynamic anaesthesia, a multicentre randomised clinical trial (CIPAT study) will be conducted. In the CIPAT study, patients undergoing elective major cardiac surgery under general anaesthesia will be randomly allocated to a control group and a combined iron supplementation group. Patients in the combined iron supplementation group will receive a combination iron supplementation regimen of iron sucrose in combination with Human Erythropoietin and vitamin C three times in the week prior to surgery, while patients in the control group will receive the same dose of placebo three times in the week prior to surgery. The primary endpoint is the volume of allogeneic erythrocyte infusion from the start of surgery to 5 days postoperatively. It is hypothesised that patients in the combined iron supplementation group will have fewer perioperative allogeneic red blood cell transfusions than those in the control group.
A significant percentage of patients with heart failure and reduced ejection fraction (HFrEF) or mildly reduced ejection fraction (HFmrEF) have iron deficiency who are symptomatic. This is independently associated with bad quality of life, low functional capacity, lower quality of, life and increased mortality. The prevalence of iron deficiency in HFrEF and HFmrEF patients in Jordan has not been studied in the past.
This study will address whether the additional use of Ferric Derisomaltose on top of standard care will improve exercise capacity and quality of life in patients with acute heart failure and iron deficiency. One group of participants will receive treatment with Ferric Derisomaltose and the other group will receive normal saline 0.9% as placebo.
The goal of this clinical trial is to determine if taking a mineral-enriched powder can raise blood iron levels compared to a placebo powder in reproductive-aged women with iron deficiency. The main questions it aims to answer are: - Does the mineral-enriched powder raise blood iron levels compared to a placebo powder in women when it is taken every day for six months? - How many participants still have iron deficiency after six months of taking the mineral-enriched powder compared to a placebo powder? Participants in this clinical trial will drink the mineral-enriched powder containing ferrous iron and zinc sulphate monohydrate or a placebo powder mixed with 1 litre of water daily for six months. The placebo is a look-alike substance that does not contain active ingredients (iron and zinc). Participants will also have to: - Complete an online "study diary" every two weeks for six months - Provide a blood sample once a month for six months - Attend three in-person visits with a researcher, at enrolment (baseline), midline (three months), and endline (six months) - Complete three sets of online questionnaires (following each in-person visit) - Complete three sets of dietary assessments (following each in-person visit) - Provide three stool samples (following each in-person visit)
Oral iron supplements are a cornerstone therapy for treating iron deficiency and iron deficiency anemia, aiming to replenish low iron levels in the body. These supplements typically contain various iron salts, such as ferrous sulfate, ferrous gluconate, ferrous fumarate, ferric maltose and ferric pyrophosphate. Each salt differs in elemental iron content and potential side effects, allowing for tailored treatment based on individual patient needs and tolerability. Moreover, advancements in carrier systems, such as microencapsulation or complexation can enhance the absorption and bioavailability of iron supplements. By improving absorption, these carrier systems may mitigate gastrointestinal side effects and increase the efficacy of iron therapy.
This study will address whether the additional use of Ferric Derisomaltose on top of standard care will improve exercise capacity and quality of life in patients with acute heart failure and iron deficiency. One group of participants will receive treatment with Ferric Derisomaltose and the other group will receive normal saline 0.9% as placebo.
Is there effect of yoga breathing exercises versus aerobic exercise on hematological parameters in iron deficiency anemic females? The purpose of the study is to investigate the effect of yoga breathing exercises versus aerobic exercise on hematological parameters in iron deficiency anemic females
Iron deficiency (ID) anemia (IDA) is a global public health problem, with the highest prevalence in Africa. Vaccines often underperform in low- and middle- income countries (LMIC), and undernutrition, including ID, likely plays a role. Recent studies have shown the importance of iron status in vaccine response. Intravenous iron given at time of vaccination improved response to yellow fever and COVID-19 vaccines in IDA Kenyan women. Whether oral iron treatment would have a similar beneficial effect on vaccine response is uncertain. Also, timing of oral iron treatment needs further investigation. The co-primary objectives of this study are to assess 1) whether IDA in Kenyan women impairs vaccine response, and whether oral iron treatment improves their response; 2) the timing of oral iron treatment to improve vaccine response (prior to vaccination vs at time of vaccination). We will conduct a double-blind randomized controlled trial in southern Kenya to assess the effects of iron supplementation on response to three single-shot vaccines: Johnson & Johnson COVID- 19 (JJ COVID-19), the quadrivalent meningococcal vaccine (MenACWY) and the typhoid Vi polysaccharide vaccine (Typhim Vi). Women with IDA will be recruited and randomly assigned to three study groups: group 1 (pre- treatment) will receive 100 mg oral iron as ferrous sulfate (FeSO4) daily on days 1-56; group 2 (simultaneous treatment) will receive matching placebo daily on days 1-28, and 200 mg oral iron as FeSO4 daily on days 29-56; and group 3 (control) will receive matching placebo daily on days 1-56. Women in all groups will receive the JJ COVID-19 vaccine, the MenACWY and the Typhim Vi vaccine on day 28. Cellular immune response and serology will be measured at 28 days after vaccination in all groups.

Secondary purpose: To evaluate the difference of hematopoietic response rate, tolerance, acute side effects, qualtiy of life at 2 months and 3 months after concurrent chemoradiotherapy between Iron Isomaltide and oral iron supplement for treating iron-deficiency anemia patients with locally advanced nasopharyngeal carcinoma.
