Active clinical trials for "Anemia, Iron-Deficiency"

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.

The goal of this clinical trial is to compare the pharmacokinetic profile of the developed drug product and reference product in participants with iron deficiency anaemia under fasting condition. The main questions it aims to answer are: [Question 1] Is there significant difference in the pharmacokinetic profile between the ferric carboxymaltose injection (10 mL: 500 mg [calculated by iron]) provided by Sichuan Huiyu Pharmaceutical Co., Ltd. and the ferric carboxymaltose injection (trade name: Ferinject®, strength: 10 mL: 500 mg [calculated by iron]) held by Vifor France? [Question 2] Is it safe for patient to take ferric carboxymaltose injection (10 mL: 500 mg [calculated by iron]) provided by Sichuan Huiyu Pharmaceutical Co., Ltd. under fasting condition? Participants will be randomly divided into two groups by stratified blocked randomization, with equal number of patients in each group,to receive test product or reference product according to the protocol below. Dosing on D1: Group T (Test product) Group R (Reference product) PK blood sample collection Safety evaluation

The INERTIA trial is a multicenter double-blinded randomized trial of intravenous iron supplementation in patients with severe aortic stenosis and iron deficiency undergoing TAVI or SAVR. The primary endpoint is the time to HF hospital admission or cardiovascular death. Secondary endpoints will assess quality of life indicators and functional capacity at 6 months.

The purpose of this study is to compare maternal outcomes such as increased hemoglobin need for blood transfusion and hemoglobin level before and post partum in women with hemoglobin <9 gr/dl , treated with venofer and women treated with ferinject.

Primary Hypothesis The 24-hour post-transfusion RBC recovery of units obtained from donors exhibiting iron-deficient erythropoiesis will not meet FDA standards for clinical use. The 24-hour post-transfusion RBC recovery of units obtained after intravenous iron repletion will improve significantly and will meet FDA standards for clinical use.

One of the most common nutritional deficiencies worldwide is iron deficiency. Iron deficiency is considered the main cause of anaemia in developing countries, including those in South America. The most recent surveys report that the prevalence of anaemia is as high as, 40 and 25% in Peru. Populations living at higher altitudes may have higher iron requirements, as body iron is naturally increased in long-term high-altitude residents to compensate for the lower oxygen in the air at high altitudes. However, the effects of chronic exposure to high altitude on iron status, body iron compartments and dietary iron requirements are incompletely understood. The primary objective of the proposed research is to determine iron bioavailability of iron from biofortified potatoes at different altitudes in populations of Andean descent. Human trials will be undertaken with volunteers in the Huancavelica region of Peru (elevation: 3676 meters) as well as in Lima (elevation close to sea level). The aim is to assess the effect of altitude on the absorption from a promising iron biofortified potato cultivar. These trials require incorporation of iron stable isotopes into the meals of the bio fortified potato and the analysis of the isotopes in subsequent blood (red blood cells) samples. Stable iron istotopes are considered the golden standard to assess human iron absorption and can be safely used as tracer substances in humans. The objective of the study is to compare, in volunteer females of childbearing age, the bioavailability of iron from bio-fortified potatoes in two locations of different altitudes and quantify the effect of altitude on iron bioavailability from a potato meal consumed over 5 consecutive days.

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.

The purpose of this trial is to compare the safety profile using equal doses of intravenous iron dextran versus iron sucrose. The researchers hypothesize that significantly more patients receiving intravenous iron dextran (using the current intermediate molecular weight product) will have severe adverse outcomes than patients receiving iron sucrose in the adult non-hemodialysis outpatient population. Secondly, since these severe reactions may require additional nursing time and physician interventions that may negate any cost advantage of iron dextran, the researchers hypothesize that iron sucrose will be more cost-effective than iron dextran.

Patients with IDA and for whom fast replenishment of iron stores is necessary, e.g. if its not appropriated to postpone surgery, will be identified within 28 to 42 days before surgery. Patients will be randomised to receive either Polyglucoferron intravenously (i.v.), Ferric Carboxymaltose i.v. or oral iron substitution with Ferrous sulfate.
