Active clinical trials for "Anemia"

This study will explore what may cause people with sickle cell anemia to have heart problems and an increased risk of sudden death. People 18 years of age and older with sickle cell anemia may be eligible for this study. Candidates are screened with a medical history and physical examination, electrocardiogram (EKG), echocardiogram (heart ultrasound), and blood tests. Participants undergo the following tests and procedures: Holter monitoring: The patient wears a small, battery-operated device to record heart rate and rhythm over 24 to 48 hours. QRST surface mapping: An EKG using 64 electrodes is done at rest and during exercise to provide a detailed look at the heart and its conduction system. Chest x-rays are taken to examine the lungs. Bicycle exercise echocardiography test: Blood pressure, pulse, heart rhythm and oxygen use are monitored while the patient exercises on a stationary bicycle. Ultrasound pictures are also obtained during the exercise. Echocardiogram: A heart ultrasound is done to check how well the heart is pumping blood. Pulmonary artery catheterization: A catheter (plastic tube) is inserted into a vein and advanced to the chambers of the heart, through the heart valve and into the lung artery. The pressures in the heart and lung blood vessels are measured while the patient is resting and during exercise, with the bed tilted up and down, and after giving 500 mls of fluid into a vein. Blood tests are done to measure a hormone called brain natriuretic peptide, which can increase with the development of heart failure, and nitrite, a substance that can affect blood vessel dilation. Some blood is stored to test for inflammatory markers and for possible future gene and protein analysis. Cardiac magnetic resonance imaging (cMRI): The patient lies in a donut-shaped magnet while pictures of the heart are obtained using a magnetic field and radio waves. Earplugs are worn to muffle the loud sounds that occur with electrical switching of the magnetic fields. A contrast agent called gadolinium may be injected to enhance the quality of the images. Invasive electrocardiographic (reveal) monitoring: This procedure permits study of the heart rhythms over a long time period. A small device is placed just under the skin on the left side of the chest. It can be left in for up to 14 months to monitor the heartbeat continuously during this time.

To conduct incidence and case-control studies of aplastic anemia in metropolitan Bangkok, Thailand

The human intestinal tract harbours a diverse and complex microbial community which plays a central role in human health. It has been estimated that our gut contains in the range of 1000 bacterial species and 100-fold more genes than are found in the human genome . This community is commonly referred to as our hidden metabolic 'organ' due to their immense impact on human wellbeing, including host metabolism, physiology, nutrition and immune function. It is now apparent that our gut microbiome coevolves with us and that changes to this population can have major consequences, both beneficial and harmful, for human health. Indeed, it has been suggested that disruption of the gut microbiota (or dysbiosis) can be significant with respect to pathological intestinal conditions such as obesity and malnutritio, systematic diseases such as diabetes and chronic inflammatory diseases such as inflammatory bowel disease (IBD), encompassing ulcerative colitis (UC) and Crohn's disease (CD) . The role of the gut microbiome in human health and disease is becoming clearer thanks to high throughput sequencing technologies (HTS) as well as parallel recent developments in non genomic techniques.

Perioperative anemia is very common in patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA). This study retrospectively analyzes the use of rHuEPO and iron sucrose in patients undergoing total hip and knee arthroplasty in order to observe the short-term efficacy and safety of rHuEPO and iron sucrose.

Anemia is a common problem with pregnant women around the world. There are high rates even within industrialized nations. The main cause of anemia in pregnancy is a lack of iron. There have been medical programs that give iron vitamins to all pregnant patients at the beginning of care to decrease anemia. These programs did not adequately decrease anemia in pregnancy. Many of them gave iron vitamins in doses that were low because pregnant patients sometimes have side effects to it. The next idea was to figure out which women were more at risk to get anemia and then treat them with a higher amount of iron. There are different blood tests to see how much iron stores are in the blood, but many do not work well during pregnancy. The test study staff think is the best for this is ferritin. The goal of this first small study is to see if healthcare providers can use the level of ferritin to predict anemia in pregnancy. This would then help to better screen, diagnose, and treat anemia during pregnancy. Study staff will enroll obstetric patients from the Women's Medicine Center and compare ferritin levels in these patients early in pregnancy with diagnosis of anemia later in pregnancy.

Efficacy of BCR Inhibitors in the Treatment of Autoimmune Cytopenias Associated with Chronic Lymphocytic Leukemia (CLL): A Retrospective Analysis of the French Innovative Leukemia Organization (FILO)

This is a sub-study parallel to ProPBM : A Randomised Control Trial Comparing a Modified Patient Blood Management Protocol Against Standard Care for Patients Undergoing Major Surgery (NCT03888768). Only female participants of ProPBM will be included in this sub-study. Association between anaemia and handgrip strength and the effect of intravenous iron therapy as part of ProPBM protocol within female participants is elucidated in this study.

Oncologic patients experience anemia and anemia is associated with poor prognosis. Transfusion is associated with adverse events, and equipoise remains on the optimal transfusion strategy in oncologic patients in surgical setting. The primary objective of this study is to determine the impact of anemia and red blood cells (RBC) transfusion on post-operative complications and mortality.

A number of RCT studies have shown the safety and effectiveness of oral Roxadustat in the treatment of renal anemia, but there is a lack of evidence from cohort studies. A prospective cohort study is planed to conduct to evaluate the efficacy and safety of Roxadustat for renal anemia in the real world.
