Iron Supplementation and Anemia After Sleeve Gastrectomy

The goal of this observational study is to learn if taking extra iron pills after weight loss surgery helps prevent low iron and anemia compared to just taking a standard multivitamin. The main question it aims to answer is: Does a specific iron supplementation plan lower the number of patients who develop iron deficiency anemia in the 6 months after sleeve gastrectomy surgery? Researchers will compare two groups of patients from different hospital units to see if the extra iron works: Patients from one unit who take a prophylactic iron supplement (Ferrodep, 60 mg per day) in addition to their standard multivitamin. Patients from another unit who take only a standard multivitamin (Centrum Silver). Participants in this study will: * Have their blood tested for iron and anemia levels before surgery, and again at 3 and 6 months after surgery, as part of their regular post-operative care. * Be asked about their health and quality of life during follow-up clinic visits. * Have their medical information from their hospital records reviewed by the study team to track their progress.

Sucrosomial Vs Intravenous Iron for Preoperative Anemia

50 patients with anemia scheduled for heart surgery or procedures will be randomized to receive either oral sucrosomial iron or standard-of-care intravenous iron before surgery to see if the oral iron is as effective as intravenous iron in increasing the red blood cell count.

Reticulocyte Hemoglobin Equivalent (RET-He) in Early Detection of Iron Deficiency Among Blood Donors and Its Potential Impact on Donor Eligibility and Transfusion Safety

Blood donation is essential for healthcare, but repeated whole-blood donation can deplete the body's iron stores. Standard pre-donation screening relies on hemoglobin levels to ensure donor safety; however, a drop in hemoglobin is a late sign of iron deficiency. Consequently, donors with subclinical or latent iron depletion often pass standard pre-donation screening unnoticed. The primary purpose of this study is to evaluate the clinical utility of Reticulocyte Hemoglobin Equivalent (RET-He) as an early laboratory marker for detecting iron deficiency among accepted blood donors. Because reticulocytes are newly formed red blood cells, RET-He reflects iron availability for hemoglobin production over the preceding few days, potentially detecting iron limitation much earlier than mature red blood cell indices or standard hemoglobin testing. In this prospective observational study, approximately 300 eligible voluntary blood donors aged 18 to 60 years will be enrolled at the Main Blood Bank of Assiut University Hospitals. At the time of routine donation, blood samples will be analyzed for complete blood count (CBC) with RET-He, serum ferritin, iron profile (serum iron, total iron-binding capacity, and transferrin saturation), and C-reactive protein (CRP) to control for inflammation. Participants will also be reassessed at their subsequent regular donation visit (after 90 days for males and 120 days for females) to evaluate changes in iron indices over time and explore whether adding RET-He improves donor eligibility assessment and long-term donor health.

Preconception vs First-Trimester Screening and Treatment for Iron Deficiency Anemia

Non-Interventional Study of Ferretab® Comp. (Ferrous Fumarate + Folic Acid Prolonged-Release Capsules) Effects in Adult Patients With Iron Deficiency Anemia and Cardiovascular Disease

The goal of this observational study is to learn how well Ferretab® comp. works and how safe it is for adults with iron deficiency anemia and cardiovascular disease who are receiving treatment as part of their usual medical care. The main questions it aims to answer are: * Does treatment with Ferretab® comp. improve anemia? * Does treatment with Ferretab® comp. improve heart-related symptoms, exercise tolerance, and overall well-being? * What side effects do participants have while taking Ferretab® comp.? This is a non-interventional study. Participants will receive Ferretab® comp. because their doctor has already decided to prescribe it as part of routine medical care. Ferretab® comp. is an oral medicine that contains iron (as iron fumarate) and folic acid. The study will not change their treatment. Participants will: * Take Ferretab® comp. for 12 weeks as prescribed by their doctor. * Attend study visits at the start of treatment, after about 4 weeks, and after about 12 weeks. * Have routine blood tests and health assessments during the study. * Report any side effects and record information in a patient diary. * Answer questions about their symptoms, exercise tolerance, and how easy the treatment is to use.

Donor Breast Milk 2

The goal of this clinical trial is to determine the serum ferritin level and hematocrit level in very preterm infants receiving donor breast milk(DBM) with an early iron supplementation protocol . The main questions it aims to answer are: Does earlier iron supplementation provide increased ferritin levels at 14 and 28 days of life in subjects fed primarily donor breast milk? Iron supplementation will be implemented when the infant achieves 80ml/kg/day of enteral feeds, as contrasted to the current protocol of full feeds (140 to 160ml/kg/day), the latter usually by Day 14 of life. At day of life(DOL) 14 (± 4 days), a blood sample will be obtained for serum ferritin determination. Similarly, a second blood draw would be performed at day of life 28 (± 4 days) or prior to discharge, whichever comes earlier

Daily Iron vs Every-other-day Iron for Pediatric Patients With IDA

Iron Deficiency Anemia (IDA) is a prevalent global health issue affecting a significant proportion of the population, including children. While daily oral iron supplementation is a common approach to treat IDA, concerns regarding side effects and compliance have led to exploration of alternative dosing schedules, such as every-other-day. This study aims to investigate the efficacy and safety of daily versus every other day oral iron supplementation in the management of IDA in pediatric patients.

FACE-APPS-Based Approach for Improving Iron Deficiency Anaemia Indicators Among Female Adolescents at Marginalized Communities

This study aims to evaluate the effect of the Face-to-face Assisted Counselling with Enhanced Application School-Based Approach (FACE-APPS-Based Approach) on anemia indicators among female adolescents. The study is a prospective, randomized controlled trial. A total of 160 female adolescents with hemoglobin levels below 12.0 g/dL will be recruited from 7 secondary schools. Random assignment at the individual level, stratified by baseline anemia status, will be used to ensure balance. For participants in the intervention group, the intervention will be designed by an interdisciplinary team and administered over 4 months, comprising 8 face-to-face counseling sessions and 8 parallel mobile application modules. Control group participants will receive standard care (diagnosis and referral). The primary outcomes are the mean differences in hemoglobin and serum ferritin levels. Secondary outcomes are engagement among female adolescents (attendance at counseling sessions and completion of mobile application modules).

The Effect of Combined Iron Protocols on Perioperative Allogeneic Transfusion

The goal of this clinical trial is to learn if a combined iron supplementation regimen can reduce the need for blood transfusions in adults with iron-deficiency anemia undergoing major elective cardiac surgery. The trial will also look at whether this regimen is safe and well tolerated. The main questions it aims to answer are: Does the combined regimen lower the amount of allogeneic red blood cell transfusion needed during and after surgery? Are there any side effects or safety concerns associated with the regimen? Researchers will compare the combined iron supplementation (sucrose iron, erythropoietin, and vitamin C) to standard care to see if it helps reduce blood transfusions. Participants will: Receive either the combined regimen or standard care before surgery Undergo major elective cardiac surgery under general anesthesia Be monitored for blood transfusion needs and recovery up to 90 days after surgery

Darbe Plus IV Iron to Decrease Transfusions While Maintaining Iron Sufficiency in Preterm Infants

In this phase II trial, the investigators overarching goal is to demonstrate the feasibility and potential benefit of darbepoetin (Darbe) plus slow-release intravenous (IV) iron to decrease transfusions, maintain iron sufficiency and improve the neurodevelopmental outcomes of preterm infants. Investigators hypothesize that in infants \< 32 completed weeks of gestation, combined treatment with Darbe plus Ferumoxytol (FMX) or Darbe plus low molecular weight iron dextran (LMW-ID) will: 1) be safe, 2) decrease or eliminate transfusions, 3) maintain iron sufficiency, 4) result in higher hematocrit and 5) improve neurodevelopment. Investigators further hypothesize that when compared to oral iron supplementation (standard care), IV iron will be better tolerated, with less effect on the gastrointestinal (GI) microbiome

Acupoint TENS vs Resistance Training for Iron Deficiency Anemia

The current study is designed to compare between the effect of transcutaneous electrical acupoint stimulation and resistance exercises on hemoglobin level in women with iron deficiency anemia.The design of this study will be a randomized controlled trial (RCT) pretest post-test assessment.Sixty women diagnosed with iron deficiency anemia will be recruited in this study from Kafrelshiekh University Hospital, Kafrelshiekh Governorate, Egypt. Their ages will be ranged from 20 to 30 years old, and they will be randomly divided into three equal (n= 20) groups. Change in hemoglobin concentration (g/dL) after the intervention period and changes in RBC count, MCV, MCH, RDW, serum ferritin, fatigue level, and functional exercise capacity after treatment will be measured.

Intravenous Iron to Treat Postoperative Anemia in Older Cardiac Surgery Patients

Postoperative anemia is common in cardiac surgery with cardiopulmonary bypass. Iron deficiency delays the recovery from postoperative anemia and may negatively affect the postoperative trajectory of cardiac surgery patients. The objective of the study is to determine the effect of treatment of postoperative iron deficiency anemia with intravenous iron on disability 90 days after surgery. This will be evaluated in a randomized placebo-controlled double blind two-center trial in which 310 elective cardiac surgery patients will be included.

Effect of Weight Loss on Hepcidin Levels and Iron Status in Subjects With Obesity.

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 Study to Evaluate Ferumoxytol for the Treatment of Iron Deficiency Anemia (IDA) in Pediatric Subjects

This is a Phase 3, randomized, open-label, multicenter, study in male and female pediatric subjects (2 years to \<18 years of age) with IDA, or felt by their clinician to be at risk of developing IDA. This study allows for enrollment of subjects with IDA regardless of etiology, except for CKD subjects (pediatric CKD subjects are being studied in a separate ferumoxytol protocol).

Observational, descriptive, prospective, longitudinal, multicenter, non-interventionist and multicentric study in Mexican subjects diagnosed with mild to moderate iron deficiency anemia (ADH). Main objective:To evaluate the effectiveness and acceptability of LISEFEX® supplement in patients with mild to moderate iron deficiency anemia.Design The minimal risk study, no therapeutic interventions were carried out by the research team. The indication for supplementation with LISEFEX® was made by the treating physician as part of standard clinical practice, while the study was limited to systematic collection of clinical and laboratory information during participant follow-up.

Alternate-day Versus Daily Oral Iron Therapy in Children With Iron Deficiency Anaemia

The goal of this clinical trial is to find out whether Iron (III)-hydroxide polymaltose complex (IPC) given on an alternate-day schedule works as well as daily dosing in treating iron deficiency anaemia in children. The study will also look at the safety and tolerability of IPC. The main questions this study aims to answer are: Does alternate-day oral IPC improve haemoglobin levels and serum ferritin level as effectively as daily oral IPC? Does alternate-day dosing reduce gastrointestinal side effects compared to daily dosing? Does alternate-day dosing improve treatment adherence in children? Researchers will compare alternate-day IPC with daily IPC to determine the most effective and well-tolerated dosing schedule for children with iron deficiency anaemia. Participants will: Receive oral Iron (III)-hydroxide polymaltose complex either daily or on alternate days for 12 weeks treatment period Attend regular clinic visits for clinical assessment and blood investigations Be monitored for adverse effects, adherence to treatment, and improvement in haemoglobin and serum ferritin levels

Postoperative Intravenous Ferric Derisomaltose for Prevention of Long-term Anemia After Cardiac Surgery

Postoperative anemia is highly prevalent among patients undergoing cardiac surgery and is associated with delayed functional recovery, increased morbidity, and impaired long-term outcomes. Preoperative iron deficiency is common in this population and contributes to inadequate erythropoietic recovery after surgery. Functional iron deficiency frequently develops even in patients without preoperative deficiency due to blood loss, hemodilution, and inflammation-mediated disruption of iron homeostasis. Despite this clinical burden, standardized strategies for postoperative anemia management have not been established. This prospective, randomized, double-blind, placebo-controlled clinical trial evaluates whether early postoperative intravenous iron supplementation improves long-term anemia outcomes in patients undergoing cardiac surgery with cardiopulmonary bypass. Adult patients with preoperative anemia (hemoglobin \<13 g/dL) or iron deficiency (ferritin \<100 ng/mL or transferrin saturation \<20%) will be screened. Eligible participants with postoperative day (POD) 1 hemoglobin \<10 g/dL will be randomized in a 1:1 ratio to receive either ferric derisomaltose (20 mg/kg, maximum 1,000 mg) or a matched placebo administered intravenously over 30 minutes on POD 1. All perioperative management outside the intervention follows current institutional standards. The primary outcome is the incidence of anemia at 6 months following surgery. Secondary outcomes include perioperative hemoglobin trends, functional recovery assessed by cardiopulmonary exercise testing and the 6-minute walk test at 6 months, transfusion requirements, postoperative complications including MAKE-90 and STS major morbidity, and changes in biomarkers of erythropoiesis and iron metabolism (erythroferrone, erythropoietin, hepcidin, and iron profile). Blood samples for biomarker analysis are collected at predefined perioperative timepoints. Ferric derisomaltose allows high-dose single-session iron repletion with a favorable safety profile and minimal risk of anaphylaxis when administered slowly. Prior studies in cardiac surgery and heart failure populations support its efficacy and safety at doses up to 20 mg/kg. The intervention is expected to facilitate erythropoietic recovery, reduce the duration of postoperative anemia, and improve long-term functional status. The trial aims to generate evidence to inform postoperative anemia management strategies in cardiac surgery patients.

Trial of IV vs Oral Iron Treatment of Iron Deficiency Anemia in the Post-Operative Bariatric Surgical Patient

Given the limited long-term effectiveness of traditional weight loss methods, bariatric surgery is increasingly becoming the preferred option for sustained weight loss. With the ascendancy of the laparoscopic approach, the two most common procedures are the Roux-en-Y gastric bypass (RYGB) and the vertical sleeve gastrectomy (VSG). Because bariatric surgery decreases nutrient intake through restriction, malabsorption, or both, and given that obese patients are often malnourished even before surgery, postoperative micronutrient deficiency, particularly of iron, can be a serious complication and difficult to treat. Iron deficiency anemia has been reported to be as high as 49% in the post-bariatric surgical patient. The current standard for correcting iron deficiency anemia in the post-operative bariatric surgical patient is oral iron supplements. However, oral iron therapy is known for its caustic effects on the gastric mucosa causing gastric irritation, nausea, epigastric discomfort and constipation. These debilitating symptoms lead to poor adherence and lower long and short-term efficacy. Furthermore, iron absorption from oral iron supplements when taken with food in patients with low iron stores ranges from 2 to 13% and without food 5 to 28%. An alternative and more effective method of iron replenishment is the use of intravenous iron. A litany of published trials, without contradiction, show marked superiority of intravenous iron in improving hemoglobin concentrations and iron parameters when compared to historical controls. Nonetheless, the current recommendations of the American Society of Metabolic and Bariatric Surgery nutritional guidelines, state that oral iron supplementation for IDA is the recommended first line of treatment. Studies are lacking that compare the efficacy of oral versus intravenous (IV) iron therapy for the treatment of IDA in the post-bariatric surgical patient. The aim of our study is to compare two accepted treatments for iron deficiency anemia (oral ferrous sulfate and intravenous ferumoxytol) for efficacy and speed of response in the treatment of IDA in the post-operative bariatric surgical patient. In this study, 104 bariatric surgical post-operative patients will be randomly assigned 52 each to oral or 52 to a single dose IV iron treatment using double-blind procedures. The primary outcome will be determined at 6 weeks of treatment with a follow-up at 12 months after treatment. Non-responders at 6 weeks after treatment may, if they qualify (based on inclusion/exclusion criteria), have an open-label IV iron treatment and will be followed with the same evaluations used after the first IV iron treatments.

Intravenous Versus Oral Iron for Treating Iron-Deficiency Anemia in Pregnancy

Double blind, placebo controlled, multicenter randomized trial in pregnant women in the U.S. (N=300) to test the central hypothesis that IV iron in pregnant women with IDA (Hb\<11 g/dL and ferritin\<30 ng/mL) at 13 - 30 weeks will be effective, safe and cost-effective in reducing severe maternal morbidity-as measured by maternal anemia at delivery-and will also improve offspring neurodevelopment.
