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.

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.

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

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

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.

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.

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.

Effect of Cow's Milk Kefir on Short Chain Fatty Acid (SCFA), Haemoglobin, and Ferritin Levels of Anemic Adolescent Girls

Introduction: The prevalence of anemia among adolescent girls in Indonesia is still quite high. According to the Indonesian Health Survey (IHS) in 2023, it was 18% and is still a national problem. Long-term supplementation of blood supplement tablets (TTD) as an effort made by the government to prevent/overcome anemia has caused side effects, namely dysbiosis by pathogenic bacteria. Giving cow's milk kefir containing various probiotics can overcome the side effects of supplementation, and its metabolites accelerate iron absorption so that iron status in the blood increases and ultimately restores anemia in adolescent girls. Method: It's research is an experimental study, with a Randomized Controlled Trial (RCT) design, pre-posttest design, involving research subjects of adolescent girls (15-18 years) with mild and moderate anemia, at SMKN 1, 2, and 3 Kasihan, Bantul Regency, Yogyakarta as many as 80 students. Subjects were divided into 2 groups, namely group 1 (treatment group), which was given 120 ml of cow's milk kefir every day and TTD 1 grain/week, and group 2 (control group), which was given 120 ml of cow's milk every day and TTD 1 grain/week. The duration of administration was 2 months. The study outcomes were Short Chain Fatty Acid (SCFA) levels in feces by Gas Chromatography-Mass Spectrometry (GC-MS) method, hemoglobin by Hematology Analyser method, and serum ferritin by Ferritin ELISA measured at the beginning and end of the study. Statistical analysis included univariate, bivariate, and multivariate analysis. Clinical analysis was also conducted to estimate the effect size of the treatment

Evaluating the Effectiveness of Various Iron Salts in Oral Iron Therapy for Iron Deficiency and Anemia in Healthy Adults

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, ferric maltol, ferrous gluconate, and ferric pyrophosphate. 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.

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

Effect of the Combined Programme on Perioperative Anaemia（CPPA）

We used the preoperative intervention of iron sucrose in combination with human erythropoietin and vitamin C as an innovative combination therapy. This combined treatment strategy aims to improve perioperative anaemia in patients by promoting erythropoiesis and improving iron metabolism. Compared with previous perioperative intravenous iron supplementation, this innovative combination therapy strategy takes into account multiple aspects of iron metabolism as well as the biological mechanisms of erythropoiesis, providing a more comprehensive intervention. Management of perioperative anaemia in previous studies has largely relied on single intravenous iron supplementation therapy, and although this approach has been effective in raising iron levels, its effectiveness may be limited in patients who have impaired iron utilisation or in situations where concurrent stimulation of erythropoiesis is required. The use of iron sucrose in combination with human erythropoietin and vitamin C, on the other hand, is based on an integrative therapeutic concept aimed at providing a more comprehensive response to perioperative anaemia by simultaneously promoting effective iron utilisation and erythropoiesis.

Comparison Of Efficacy Of Iron Polymaltose Complex And Ferrous Sulphate In Iron Deficiency Anemia In Pediatric Patients

This study aims to compare the efficacy of two iron preparation for the management of children presented with iron deficiency anemia. Ferrous sulphate and lron polymaltose (ferric form) are most commonly used preparations. Both drugs are easily available in market and are often recommended by pediatriclans. The efficacy, bioavail.tbilily, side effects and cost of these preparations vary. This study is designed to find out a drug with better efficacy that can be used for treatment of iron deficiency anemia in local population.

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.

Liposomal Iron 30 mg Supplement in Non-anemic Pregnant Females

Protocol Summary: Liposomal Iron Supplementation in Non-anemic Pregnant Females This observational study aims to evaluate the efficacy and safety of daily liposomal iron supplementation (30 mg) in non-anemic pregnant women during their second trimester of pregnancy. The study will focus on pregnant females aged 18-45 years with low-risk, singleton pregnancies who are non-anemic (hemoglobin ≥10.5) at 14-16 weeks gestation. Primary Research Question: Does daily supplementation with 30 mg liposomal iron effectively maintain maternal hemoglobin levels over 90 days? Measured by: The difference in maternal hemoglobin levels between baseline and after 90 days of treatment in women recruited at 14-16 weeks gestation. Secondary Research Questions: What are the effects of liposomal iron supplementation on serum ferritin levels? Measured by: Changes in serum ferritin levels between baseline and after 90 days of treatment. What is the safety profile of liposomal iron supplementation during pregnancy? Measured by: Maternal gastrointestinal side effects monitored at each prenatal visit (day 30, 60, and 90). What is the compliance rate with liposomal iron supplementation? Measured by: Participant-reported compliance assessed at each prenatal visit (day 30, 60, and 90). Participants will: Receive daily liposomal iron supplementation (30 mg) for 90 days. Attend regular prenatal visits for monitoring at days 30, 60, and 90. Complete questionnaires about compliance and any adverse effects at each visit. Undergo blood tests to measure hemoglobin and serum ferritin levels at baseline and day 90. This multi-center study will involve 714 participants across 100 sites, with recruitment beginning in November 2024 and study completion expected by July 2025. The study's findings will contribute to understanding the role of liposomal iron supplementation in preventing iron deficiency during pregnancy and its potential advantages over traditional iron supplements in terms of tolerability and compliance.

Iron Deficiency Anemia (IDA) and the Brain

This is a trial with an observational and an interventional arm, in patients with moderate to severe anemia and control subjects. The main purposes of this study is to phenotype the scope of neurocognitive deficits from iron deficiency anemia (IDA) in adult women, determine derangements in cerebral perfusion, vascular reactivity, functional connectivity, and blood brain barrier permeability in adult-onset IDA and relate them to neurocognitive deficits, as well as determine the reversibility and durability of both the physiologic and neurocognitive derangements by iron replacement therapy. All eligible subjects will be asked to provide informed consent before participating in the study.

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).

Short-term Intravenous Iron Isomaltose Anhydride for IDA

This prospective, randomized, controlled study aims to evaluate the impact of short-term intravenous iron isomaltose anhydride on postoperative recovery and the requirement for allogeneic red blood cells (RBC) transfusion in preoperative Iron-deficiency anemia (IDA) patients receiving orthopedic surgery, thus facilitating developing a simple and effective iron supplement approach for patients' recovery.

Effect of Altitude on Iron Absorption in Iron Depleted Women

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.

Impact of Benazir Nashonuma Program (BNP) on Maternal and Child Nutritional Status

The purpose of this study is to evaluate the impact of Benazir Nashonuma Program (BNP) which includes specialized nutritious food (SNF) augmented with specific reproductive health interventions during pregnancy on proportion of low birthweight babies and stunting among children, in low income setting of Pakistan. The study aims to answer if: 1. Utilization of Benazir Nashonuma Program (BNP) among pregnant women is effective in reducing the proportion of low birthweight babies, compared to pregnant women who are not utilizing the program, among low income setting population. 2. Utilization of Benazir Nashonuma Program (BNP) is effective in reducing the proportion of stunting among children, compared to those not utilizing the program, among low income setting population. Participants who are enrolled in the Benazir Nashonuma Program (receiving intervention) and those who are not enrolled (not receiving intervention) will be followed throughout pregnancy till delivery. After delivery mother-baby dyad will be followed for a period of 12 months. Compliance of supplementation will be measured, and outcomes (low birthweight and stunting) observed throughout the follow up.

Impact of Intravenous Iron on Musculoskeletal Function in Older Adults

Anaemia is a risk factor for functional decline and frailty in older adults including decreased physical performance and muscle strength, increased hospitalisation risk and mortality, falls, and poorer recovery from activities of daily living. Despite a major gap in human studies, research in animals has demonstrated an interrelationship between iron deficiency anaemia and deteriorated functional capacity and physical performance particularly in older adults. Iron deficiency and associated anaemia is a frequent accompanier of debilitating chronic diseases such as heart failure and chronic lung diseases. These conditions, more commonly seen in older patients, are strongly linked to deterioration in physical function, reduced skeletal muscle mass and quality, frailty, and poor quality of life. Exercise intolerance is also a common feature of these conditions as iron deficiency impairs the capacity of carrying oxygen leading to inability to sustain physical activities. Furthermore, the age-related decline in the muscle mass and quality (so called sarcopenia) and associated frailty has rapidly become a major health concern in the older adults particularly when accompanied by other chronic diseases. Recently, there has been an increasing interest in exploring the role of iron as a causative factor in the development of sarcopenia and related frailty. In summary, there is a substantial gap of evidence whether Iron repletion leads to meaningful enhancements in the skeletal muscle function and physical performance in older adults suffering from iron deficiency anaemia. This study will investigate the impact of a standard care intervention (intravenous iron therapy) on muscular function and physical performance in older patients through a range of laboratory assessments.

Preoperative Intravenous Iron Therapy in Patients With Gastric Cancer

The main objective of this investigator initiated study is to study if preoperative intravenous iron is effective in reducing need for allogenic blood transfusion in patients with gastric cancer who will undergo a standardized gastrectomy including both total and subtotal gastrectomies. The hypothesis is that intravenous iron reduces the need for perioperative blood transfusions.
