Active clinical trials for "Anemia, Iron-Deficiency"

The role of capsule endoscopy (CE) in patients with obscure / occult gastrointestinal (GI) bleeding remains unclear. This pragmatic randomized controlled trial is designed to determine the diagnostic yield and clinical outcomes of patients with obscure GI bleeding who receive CE compared to those who receive usual standard care.

This is a pilot prospective single blind controlled trial comparing magnetically steerable gastric capsule endoscopy to conventional oesophagogastroduodenoscopy in diagnosing upper gastrointestinal pathology in patients with recurrent/refractory iron-deficient anaemia.

The purpose of this study is to evaluate the feasibility and effectiveness of weekly iron and folic acid (IFA) supplementation and one-time deworming treatment at the community level in improving hemoglobin levels among adolescent girls in Liberia, West Africa, and to assess the feasibility and effectiveness of a targeted nutrition education program in improving nutrition knowledge, attitudes, and practices in the same population.

The objective is to determine if a set of clinical supports that includes computer-assisted identification, an EHR registry, facilitated GI referral, and an EHR tool for documentation improves the timely referral and completion of bidirectional endoscopy in men aged 18 years and older and women aged 40 years and older with iron deficiency anemia.

This study evaluates auditory neural maturation by auditory brainstem evoked response in late preterm and term infants with in utero iron deficiency compared with neonates with normal in utero iron status.

The study is a prospective, observational study of adult, non-cardiac, non-obstetric, elective surgical patients conducted over a period of one week. This large-scale clinical audit aims to assess the incidence rates of anaemia and hyperglycaemia amongst elective surgical patients in the Western Cape. A study such as this is essential in the assessment of the incidence rates of abnormal fasting blood glucose levels and reduce the risk of perioperative complications for patients. Preoperative anaemia is a modifiable risk factor and should be identified early and treated appropriately to improve patient outcomes.

During inflammation hepcidin concentrations are increased, leading to a decrease in iron absorption. In iron deficiency anemia hepcidin is suppressed due to the activation of erythropoiesis. Whether inflammation or anemia has the stronger effect on hepcidin is uncertain.

Iron-deficient anaemic subjects are likely to benefit most from oral iron supplements, but supplementation schedules vary widely in clinical practice, absorption is low and compliance is poor due to mild gastrointestinal side effects. The investigators will compare iron absorption from labeled oral iron doses of 100mg and 200mg administered either on two consecutive days or on alternate days in young anemic women.

Red blood cells contain a chemical called haemoglobin which carries oxygen from the lungs around the body. When the amount of haemoglobin is reduced, a patient is 'anaemic'. Anaemia can have many causes, but affects about a third of patients having major surgery in hospital. After their operation these anaemic patients are more likely to suffer serious complications. This may be because the body needs extra oxygen - and so enough haemoglobin - to heal and recover successfully from the trauma of surgery. For a similar reason, patients' overall fitness before surgery is very important. Less fit patients are much more likely to get complications after surgery. To help us assess the risk of complications, the investigators measure patients' fitness before surgery using a cycling exercise test. The investigators monitor a number of things that show us how well the heart, the lungs and the muscles respond when they are under stress. People who are very anaemic tend to perform less well on this cycling test. Anaemia is often due to a lack of iron, which helps make haemoglobin. Usually people get iron from foods such as red meat and spinach. Some conditions mean that patients lose iron, such as a tumour bleeding. Other illnesses make it difficult for the body to absorb iron from the gut in the first place. Both lead to a state of low iron in the body and eventually this leads to anaemia. One way to treat anaemia quickly before surgery is to give iron into the bloodstream (intra-venous). It is thought that this might reduce the risk of complications after surgery, but it is not known whether this is because it improves overall fitness, or for other reasons. The investigators plan to carry out a study called CAPOEIRA-I (CArdio PulmOnary Exercise testing and IntRAvenous Iron) to find out whether giving patients intravenous iron improves their fitness. The investigators will measure this by doing a cycle exercise test before and then at least 10 days after the iron is given. The investigators will also measure how much the total amount of haemoglobin chnages with iron treatment. Intravenous iron is already routinely used for these patients, so the only additional activity for the study is the extra exercise test, some extra blood tests and the measurement of haemoglobin after the iron has taken effect.

Iron deficiency anemia is a common complication of liver cirrhosis in childern and may affects there life this study to improve the outcome of these patients
