Filter by: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.
Anaemia continues to be one of the most common health problems affecting children and pregnant women in low-income countries. Nutritional iron deficiency is believed to be the main driver of anaemia, so mass iron supplementation and food fortification programs have been recommended by most public health organizations. However, these interventions are frequently ineffective and new strategies are desperately needed. Both anaemia and iron absorption are influenced by multiple factors, including nutritional status, infection, low grade inflammation and host genetics. The discovery of hepcidin, the master regulator of iron absorption and regulation has opened new avenues for investigation. Genome-wide association studies have identified several single nucleotide polymorphisms (SNPs) within hepcidin regulatory genes that are associated with altered iron status both in African populations. The study aims to investigate the impact of genetic alterations in hepcidin regulation on oral iron absorption. A recall-by-genotype study will be conducted using an existing database of pre-genotype individuals in rural Gambia (West Kiang). This database comprise of data on >3000 Gambians, with Illumina HumanExome array data on 80K directly genotyped putative functional variants as well as imputation data on 20M variants.
For Non-dialysis subjects with anemia associated with chronic kidney disease, demonstrate non-inferiority of MT-6548 compared to darbepoetin alfa using Hb value and evaluate long-term safety of MT-6548. For subjects not currently receiving ESAs, evaluate Hb correction and maintenance effect of MT-6548 and for subjects currently receiving ESAs, evaluate Hb conversion and maintenance effect of MT-6548
Anemia prevalence in orthopedic surgery is up to 30 %. Identifying those patients prior to surgery and treating them would be ideal. Different ways of determining hemoglobin Levels are available. In this study classical laboratory determination, determination with HemoCue® and Rad-67™ will be performed to compare precision of those three methods as well as their correlation.
To investigate the efficacy of posaconazole as prophylaxis antifungal agent in aplastic anemia / hypoplastic myelodysplastic syndrome (AA/hMDS) patients undergoing antithymocyte globulin (ATG) treatment
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.
The investigators assess and compare the efficacy of anemia treatment in pregnant women with anemia of chronic disease with true iron deficiency and in women with iron deficiency anemia.
The effectiveness of micronutrient powders or MNP as a strategy for the prevention of micronutrient deficiencies has been described in the literature. However, few studies have shown the impact of the inclusion of other simultaneous actions on the different dimensions of food and nutritional security (as in the case of the project "Papas más nutritivas") that will contribute to the improvement of nutritional status, obtaining potentially greater benefits. The objective is to establish the existence of difference in hemoglobin values (and other biochemical parameters as secondary outcomes) among children aged 6 months to 5 years who receive home fortification with micronutrient powders (MNP) belonging to the project "Papas más nutritivas", and children with home fortification with MNP but not belonging to the project.
The objective of this study to evaluate the efficacy FG-4592 for the treatment of anemia in Chinese participants with lower risk MDS.
This is a prospective observational study on incident peritoneal dialysis patients on the effect of hemoglobin level and vascular reactivity using the generic erythropoietin alpha. The objective of the study is to to describe the effect of improvement in hemoglobin level and the flow-mediated dilatation using Epoeitin Alpha (Renogen). Patients who will meet the inclusion and exclusion criteria will have their baseline laboratory test and ultrasound of the brachial artery to assess the flow mediated dilatation. This is a 3-month follow up study with a monthly laboratory test to monitor the patients. The following are the outcome measures: hemoglobin level, vascular reactivity by measuring the flow mediated dilatation of the brachial artery and blood pressure.
