View clinical trials related to Iron Deficiency Anemia.
Filter by:Iron deficiency anaemia (IDA) is common in inflammatory bowel disease (IBD). However, although iron is commonly prescribed, the amount of elemental iron needed to achieve clinical efficacy, and the optimal method of supplementation, are under debate. This pilot study aims to investigate the efficacy and safety of low dose and standard dose oral iron preparations for the treatment of IDA in patients with IBD.
Iron deficiency anemia (IDA) is a widespread condition affecting many people globally. Despite the many cases of IDA, there are few studies that compare the effectiveness of different types of iron supplements with a greater emphasis on the cost of supplements and their tolerability. This study aims to conduct a comparison between different iron supplements to determine the superiority of the iron supplements Ferrous Ascorbate (EBMfer) and Ferrous Fumarate (Eurofer) over polysaccharide iron (FeraMax). This comparison will be conducted by determining the change in hemoglobin levels for participants in this trial over a 3-month period.
The prevalence of iron deficiency in pediatric cardiac surgery patients is not very well known. Iron deficiency can lead to anemia, higher transfusion rates and possibly higher complication rates. In this retrospective study, the iron status of all patients undergoing pediatric cardiac surgery at our institution between January 2019 and december 2023 will be analyzed. Together with iron status, transfusion requirements as well as complications will be recorded. Iron status will be reported with descriptive statistics, patients with or without iron deficiency will be compared using non-parametric tests.
The goal of this clinical trial is to evaluate, if a change in dosing strategy in oral iron supplementation from leads to an improvement of iron absorption and consequently a faster therapy in patients with iron deficiency anemia. The main question the study aims to answer is: Does a treatment effect (measured by change in hemoglobin after 12 weeks of treatment) exist between daily oral iron supplementation and interval administration (every second day)? Participants will receive oral iron supplementation every second day with double the standard dose (intervention group). Researchers will compare this group with the active control group, that receives oral iron supplementation every day with the standard dose. Participants will present for three patient visits (at baseline, after 6 and after 12 weeks of treatment).
This project aim to investigate whether wireless capsule endoscopy(WCE) has a similar diagnostic yield as conventional endoscopy in detecting the cause of iron deficiency anemia (IDA)
a randomized clinical trial to compare the effect of twice weekly versus daily iron therapy in treating anemia in children with cerebral palsy, to be conducted at Department of pediatric medicine children's hospital PIMS islamabad.
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.
Obesity and iron deficiency are the nutritional disorders with the highest prevalence worldwide. Different mechanisms have been proposed to explain iron deficiency secondary to obesity. Among the most studied is the deficit in dietary iron intake or the increase in blood volume that increases the need for the metal. However, one of the most plausible mechanisms linking obesity and iron deficiency is low-grade systemic inflammation, through the iron metabolism intermediate known as hepcidin. The investigators objective is to evaluate the effect of weight loss by caloric restriction on hepcidin and serum iron concentration in people living with obesity and iron deficiency. The study will be divided into two phases: Phase 1: A cross-sectional study (cases and controls) to compare hepcidin levels, iron status and inflammatory markers in people living with and without obesity. The second phase consists of an open-label randomized controlled clinical trial. Individuals living with obesity who are iron deficient will be recruited and randomized to one of 2 dietary intervention groups with 60-day follow-up. The intervention groups will be: diet with caloric restriction rich in protein (with red meat) and diet with caloric restriction rich in protein (without red meat). Hepcidin levels, iron status and inflammatory markers will be determined at the beginning and end of the intervention. The nutritional intervention will have the following distribution of macronutrients in the diet: protein 1.5 g/kg of ideal weight, 50% carbohydrates and 25-30% fats.
- Rationale and background: Surgical patients' transfusions have changed from replacing surgically lost blood with allogenic blood transfusions to implementing strategies that reduce transfusion requirements. Patient Blood Management (PBM) is designed to maintain hemoglobin concentration, optimize hemostasis, and minimize blood loss to improve patient outcomes. There is mounting evidence that multimodal PBM programs can improve postoperative outcomes and reduce perioperative blood transfusions and costs. The TULIP study in Turkey showed higher uses of blood transfusions in major surgical patients, including coronary artery surgeries in Turkey. The current studies also support the preoperative use of intravenous iron and/or vitamin B12/folic acid in major surgical patients. So, we aim to evaluate the efficacy of implantation of PBM in CABG surgeries in Turkey. - Research question and objectives: Is it possible to decrease the amount of perioperative blood and blood products transfusions by implementing PBM in patients who underwent CABG surgeries? The primary objective of the study is to demonstrate the reduction in perioperative RBC units transfused, when PBM is implemented in cardiac surgery in Turkey. The secondary objectives are to evaluate the concurrent reduction of FFP, platelet and total blood products used as compared to a control group, length of hospital and ICU stay following the surgery. - Study design: A prospective, multicenter, non-interventional study with a historical/retrospective control group. - Population: Patients who are operated on for coronary artery bypass grafting. - Variables: Demographic (age, sex), clinical (body mass index, comorbidities, ASA score, P-POSSUM score, Charlson Comorbidity Index), operative (type and duration of operations), laboratory (hemoglobin, platelet count, coagulation profile), laboratory for anemia (transferrin saturation, ferritin, creatinine clearance), preoperative treatment, transfusion data, and outcome (morbidity, mortality, lengths of hospital stay). - Exposures: Preoperative IV iron treatment of anemia. - Data sources: Medical data of the patients are obtained after entering a prespecified database (e-CRF) for the study subjects. For the control group, the medical data of the patients will be obtained retrospectively from the database of the TULIP study. - Study size: Study group: A total of 368 patients from five different centers across Turkey. Control group: at least 368 patients from the same centers attending the TULIP study. Finally, 736 patients will be included for the study.
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.
