Active clinical trials for "Anemia"

Addressing micronutrient deficiencies in Zambia is recognized as a national priority by the government due to its major contribution to morbidity and mortality among children, especially infants in their formative years. One of the most successful, cost-effective, and recommended strategy to address micronutrient malnutrition is 'in-home fortification' with micronutrient powders (Sprinkles being the most widely recognized) along with nutrition education. While this intervention has proven to be safe, effective, and efficacious in numerous other countries, a specific national protocol must be developed to maximize its effect on reducing anaemia in Zambian children. The proposed research aims to inform such protocol.

Sickle Cell disease is caused by an inherited hemoglobin disorder. Healthy red blood cells are discoid and can deform and move through small blood vessels to carry oxygen to all parts of the body. In Sickle Cell disease, as red blood cells circulate and oxygen is released, the deoxygenated abnormal Hemoglobin S can begin to polymerize and cause red cells to become sticky and elongated. These "sickled" red cells are less flexible and will obstruct small blood vessels and prevent normal red cells from circulating freely, which limits oxygen delivery to tissues and organs. This is known as a "sickling crisis" or "vaso-occlusive crisis" and is the leading cause of hospitalization in patients with Sickle Cell disease. Patients suffering from a sickle crisis experience severe pain and are at risk of stroke, heart attack or even death. Current therapy is limited to hydration and symptomatic pain relief. The administration of MP4CO as an adjunct treatment to standard therapy may alleviate pain associated with a sickling crisis and potentially reduce the severity and duration of a crisis. This may shorten the time in hospital and potentially improve the quality of life for patients with sickle cell anemia.

Background: - Anemia occurs commonly and is associated with poor outcomes in the elderly. In about a third of anemia cases in older people (over age 65), the cause of anemia is unexplained. Anemia in older adults may be caused by the bone marrow's inability to produce red blood cells fast enough to replace older red blood cells that have died. Researchers want to look at unexplained anemia by studying the life span of red blood cells in younger adults and older adults. To do so, a vitamin called Biotin will be used as a marker on the red blood cells. Objectives: - To investigate possible causes of unexplained anemia in older people. Eligibility: Individuals in the following groups: Men and women between 18 and 50 years of age who do not have anemia Men and women at least 70 years of age who do not have anemia. Men and women at least 70 years of age who have iron-deficiency anemia. Men and women at least 70 years of age who have anemia with no known cause. Design: Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Participants will have an overnight stay for the first study visit. They will provide a blood sample to which Biotin will be added. The blood sample with Biotin will then be returned to the participant. Twenty-four hours later, another blood sample will be collected. Participants will have up to 14 additional study visits. At each visit, blood samples will be collected to measure the amount of Biotin remaining in the blood. Participants may also provide a separate blood sample for genetic testing. These tests may provide more information about genetic causes of unexplained anemia.

Several studies using new forms of intravenous iron showed that it is effective in treating perioperative anemia in orthopedic and digestive surgery. Effects of ferric carboxymaltose have not been assessed in the settings of cardiac surgery. This study will compare ferric carboxymaltose to placebo in a randomized trial design where ferric carboxymaltose / placebo will be administered in the postoperative period (Day 1) after cardiac surgery. A total sample size of 200 patients (100 per group) will be needed. The FCAACS trial will assess the impact of administering intravenous iron (Ferric carboxymaltose) after cardiac surgery with cardiopulmonary bypass (CPB) on the: incidence of postoperative anemia incidence of postoperative transfusion incidence of complications related to intravenous iron All the surgeries will be performed by the same surgical team and follow-up will be ensured by the same Cardiac Surgery Unit (CSU) team according to department's standard protocols. Participants in the Ferric carboxymaltose group will receive 1g of Ferric carboxymaltose diluted in 100 mL of IV isotonic serum saline, whereas participants in the Placebo group will receive 100 mL of IV Placebo

BACKGROUND Ghana has reduced food insecurity prevalence by 49.2% in two decades. However, prevalence of malnutrition especially stunting (in <children5yr) has not matched the changes in food security levels. Of several key nutritional factors that lead to stunting, nutritional status of such trace minerals as iodine, iron and zinc has not been studied. Nutritional inadequacy of these trace minerals may be detected by estimation of dietary intake, and time-consuming and costly biochemical measurements of respective biomarkers. Since there is no means to estimate dietary intake of the trace minerals in Ghana, due to incomplete food composition data of the nutrients, identifying validated non-invasive, dietary approaches to predict the biomarker status of these trace minerals are critical in counteracting the challenges surrounding the persistent stunting due to micronutrient deficiencies in Ghana. Additionally, exploring alternative approaches to providing access to foods rich in trace minerals at household level is crucial. STUDY AIMS AND HYPOTHESIS The ultimate goal of this research is to increase knowledge base on improving trace mineral status in mother-child (6-23 mo) dyads through a sustainable community-based interventions in northern Ghana. Investigators will begin with iron and iodine that impair mothers and young children's growth and cognitive development most with three aims: 1) to develop dietary screening tools that are validated by biomarkers for early detection of deficiencies, 2) to determine efficacy (dose responses) of feeding indigenous nutrient-rich meals in preventing deficiencies and improving iron and iodine status, and 3) to demonstrate sustainable and scalable improvement of food systems through a container gardening project for iron-rich Hibiscus sabdarifa for consumption and income by empowering women during the dry/lean season in northern Ghana. • Aims 1: To develop dietary screening tools that are validated by biomarkers for early detection of deficiencies among children 6-23 months and their mothers H1.1: Dietary diversity score can predict iron deficiency among children 6-23 months and their mothers. H1.2: Dietary diversity score can predict iodine status deficiency among children 6-23 months and their mothers. Aims 2: Indigenous nutrient-rich meals of hibiscus sabdarifa improves iron and iodine status of dyads H2.1: Indigenous nutrient-rich meals of hibiscus sabdarifa improves iron status of dyads H2.2: Indigenous nutrient-rich meals of hibiscus sabdarifa improves iodine status of dyads Aims 3: to demonstrate that container gardening can provide sustainable and scalable improvement of food systems for iron-rich Hibiscus sabdarifa for consumption and income during the dry/lean season in northern Ghana H3.1: Container gardening can provide adequate amounts of vegetables for mother and child dyad during the dry season H3.2: Container gardening can provide adequate income to purchase iodized salt and Amani for mother and child dyad during the dry season SIGNIFICANCE This project addresses the gap in our knowledge and practices pertaining to serious and persisting trace mineral deficiencies that result in stunting and cognitive impairment in northern Ghana. Early detection of iron and iodine deficiencies with validated non-invasive dietary screening tools (aim 1), effective indigenous nutrient-rich meal-based programs (aim 2) and sustainable/scalable and women-led community-based food-system changing agricultural project (aim 3) are expected to be the most creative approach to counteract iron and iodine deficiencies in northern Ghana. This project will utilize science and education to change practices, environments and policies to reduce the prevalence of trace mineral deficiencies at the local, regional, national and global levels.

Good nutritional status among adolescents is a window of opportunity to produce healthy adults or pregnant individuals. Modifying the dietary habits during adolescent girls may be a sustainable approach to ensure good nutritional status among population because those habits tend to stay for a life time. Over many years, there has much effort to overcome anemia. Iron supplementation and fortification have been the most popular and convenient strategies to combat anemia. However, there has not much success due to the high still prevalence of anemia among children and women reproductive age. Food-based approach has been defined as one of the most effective programs to combat or reduce the prevalence of anemia. In the meantime, food based recommendations (FBR) formulation through linear programming (LP) approach has been found to be more effective than the traditional method of developing FBRs called "trial and error". LP approach allows us to develop optimized diet for target population with addition to detect the nutrient problem in specific region. This study therefore aims to identify the nutrient problems in the community, to develop optimized FBR employing the LP approach and to assess effect of nutrition education using optimized FBR in order to improve the nutritional and hemoglobin status among adolescent schoolgirls in rural Malang City. This study was conducted in several phases: 1) cross-sectional study 2) intervention study. Cross-sectional study was aimed to formulate optimized food based recommendations using linear programming. Intervention study was performed during 20 weeks with Remaja ASIK as the tagline which means Active, Healthy, Smart, and Creative. Adolescent schoolgirls aged 14-18 years was the subject of this study and 496 subjects were selected, including 152 for first phase and 344 for third phase. In addition, selected school based on inclusion criteria: 1) not boarding schools; and 2) having large number of students. In doing data collection, we collected socioecodemoghraphic data, anthropometry, biochemical data, dietary data, and cogitive performance.

Sickle Cell Anaemia (SCA) is an inherited disease that makes the body produce red blood cells with abnormal sickle-shaped cells. The sickle-shaped cells are rigid, not flexible and break up easily resulting in anaemia. The abnormal cells also stick to the vessel walls, causing a blockage that slows or stops the flow of blood. When this happens, oxygen cannot reach nearby tissues. The lack of oxygen can cause attacks of sudden, severe pain, called pain crises, stroke or damage to important organs such as the spleen. All of these can lead to death. These attacks can occur without warning and are often started and made worse by infections such as malaria. Therefore, in many countries in Africa where malaria is common, children with SCA are given malaria medicines to prevent the infection. However, many of the medicines do not work effectively, are too difficult to take or they have side effects, resulting in poor adherence. The aim of this study is to find safe, acceptable and effective medicines for malaria prevention in children with SCA in eastern and southern Africa. The investigators propose to conduct a study to find out whether giving weekly doses of dihydroartemisinin-piperaquine, also called DP, is safe, more effective, acceptable and cost-effective than the current strategy of monthly sulphadoxine-pyrimethamine (SP) to prevent malaria in children with sickle cell anaemia. Overall, 548 children aged 6 months to 15 years will be chosen randomly to receive either weekly DP or monthly SP for about 18 months. To test if the study medicine is effective, the study will compare the case burden of malaria. The investigators will also monitor every child for any type of illness, blood transfusions and other complications of sickle cell anaemia and admissions to the hospital. In addition, the study will evaluate the impact of DP on the development of resistance by malaria parasites. The study will also include nested safety studies on the effect of DP on the heart. All study participants will receive all the other usual care and treatments, including patient education on home care, and daily penicillin if younger than 5 years. If proven safe and efficacious, chemoprophylaxis with DP may decrease the incidence of malaria in children with SCA, prevent ill-health and deaths, and improve wellbeing.

Anemia is known as a condition in which the hemoglobin level is lower than normal. Anemia is one of the most common complications during pregnancy. Anemia in pregnancy is defined as a hemoglobin level < 110 g/L . Anemia is an important risk factor in pregnancy which leads to both maternal and fetal morbidity and mortality. The pregnant woman needs more iron during pregnancy, so iron deficiency anemia is very common during pregnancy. In Egypt; iron deficiency anemia affects about one in every two pregnant women, especially in rural areas. Pregnant women require about 27 mg/day elemental iron to cover their increased need. The pregnant women should start taking a daily supplement of 30mg of elemental iron as a preventive measure against iron deficiency anemia especially in poor countries. Obesity is defined as having an excessive amount of body fat. The body mass index, a measurement based on height and weight, determines the obese if the figure more than 30 kg/m2. There is an increased rate of overweight and obesity among pregnant women. According to the World Health Organization, 46% of adult females in Egypt are obese. Many researches in the literature revealed a strong relationship between high BMI in pregnancy and iron deficiency anemia. Hepcidin is an iron regulating hormone in the body. Increases in iron levels in the plasma stimulate the production of hepcidin, which blocks iron absorption from the diet, so; hepcidin production is suppressed in the case of iron deficiency.

The purpose of this study is to find out more about darbepoetin alfa in children less than 1 year of age with anemia (a decrease in red blood cells) due to kidney failure. This study will see if darbepoetin alfa is safe and well tolerated and whether it causes any side effects by taking blood samples and checking vital signs (heart rate, body temperature, and blood pressure tests) at specific times throughout the study. In addition, the study will evaluate the amount of darbepoetin alfa in the blood over time and look at special markers in the blood to evaluate how darbepoetin alfa works on anemia. Darbepoetin alfa is approved by the United States Food and Drug Administration (FDA) and European Medicines Agency (EMA) for use in adults, but not for all ages of pediatric subjects. Therefore, studies need to be conducted in pediatric subjects (children) to determine the appropriate dose to use in younger children.

The purpose of this clinical trial was to determine if high-iron or low-iron formula, containing an average of 12.7 mg/L or 2.3 mg/L respectively, had differing effects on iron status in infancy and on development longitudinally.
