Filter by: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.
A randomized, double-blind, parallel, three-arms, placebo-controlled, safety and efficacy study of Botanical Extract Standardized for Iron + Vitamin C and Botanical Extract Standardized for Iron in adult human subjects with anemia or iron-deficiency anemia. A total of up to 96 adult male and female subjects of age 26 to 55 years (32 subjects/arm) will be enrolled to get 90 evaluable subjects (30 subjects/arm) in the study
- 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 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.
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.
Iron deficiency (ID) is the most common micronutrient deficiency worldwide, and poor iron bioavailability is a major cause. While 30% of female athletes are affected by ID, and its consequences are highly relevant to athletic performance, ID affects women and children around the world with consequences just as relevant, if not more so (e.g. school performance, work capacity and thus wage earning). With poor iron absorption being a cause of ID in active women, it is especially important to discover simple ways to improve iron (Fe) uptake. While some studies have suggested that consumption of prebiotic fiber may improve Fe absorption in animal models, there have been few studies examining the effects of synbiotic supplementation (consumption of both a prebiotic and probiotic that work together) on Fe uptake in adult females (athletes and non-athletes). A recent pilot study demonstrated a substantial improvement in Fe uptake in female athletes after 4 and 8 weeks of synbiotic supplementation compared to placebo during Fe repletion with a low dose of ferrous sulfate (FeSO4). If synbiotic supplementation can improve the Fe bioavailability of FeSO4 (which is ~30%) in ID women during repletion of Fe status, it could possibly improve the Fe bioavailability of non-heme Fe sources, as well as mixed meals. Research Question: What is the effect of synbiotic supplementation (a supplement containing a prebiotic + a probiotic), compared to prebiotic supplementation or a placebo, on Fe uptake and the gut microbiome in ID athletes during low-dose Fe repletion? Hypothesis: In the proposed study, we hypothesize that synbiotic supplementation along with Fe repletion with a low dose of FeSO4 will have greatest impact on athletes' Fe uptake due to alterations in the microbiome, which will be assessed.
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.
