Active clinical trials for "Anemia"

To establish a link among Chlamydia infection, sickle cell anemia, and stroke risk.

The purposes of this study are threefold: 1) to evaluate the prevalence and risks of oral complications in patients with aplastic anemia; 2) to evaluate if oral problems in these patients can predict their response to treatment; and 3) to review complications of dental treatment in these patients in order to establish treatment guidelines. This study will be performed through a review of medical charts of 79 patients with aplastic anemia and 67 patients with schizophrenia who were treated at the National Institutes of Health Dental Clinic between 1993 and 1999. The schizophrenia patients will serve as a control population. Demographic, clinical and radiographic information will be collected for all patients. Additional data collected only for aplastic anemia patients will include medical therapy, disease duration, blood cell counts, oral problems that developed during treatment and treatment response.

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.

Blood transfusion is an expensive and finite resource and optimum transfusion threshold in surgical patients is yet to be defined. Patients commonly receive blood transfusions to reduce the risk of myocardial ischaemia or improve perfusion of other organs (e.g. the kidneys), but this treatment may have important adverse effects including postoperative infection. Patients undergoing surgery for fractured neck of femur are often elderly, with co-morbidities and a high risk of postoperative complications, including MI and AKI. We propose to conduct a study with the following aims: To describe the incidence of anaemia and transfusion in patients undergoing surgery for fractured neck of femur. To use clinical and biochemical data to measure the incidence of perioperative cardiac and kidney injury in this group. To evaluate highly sensitive serum troponin and urinary MALDI-MS as possible endpoints in a future prospective randomised trial of perioperative transfusion.

Preoperative anemia is a known risk factor for morbidity, mortality and increased healthcare resource utilisation. The Investigator's previous study demonstrated the rate of preoperative anemia in Singapore General Hospital (SGH) to be at 26.6%. The rate is highest in the elderly group which stands at 49.9%. The main objective of this study is to investigate the perioperative morbidity and mortality, blood transfusion rate, healthcare outcomes and patient-centric outcomes among anemic elderly patients undergoing major surgery. The investigators hypothesize that elderly patients who undergoes major abdominal surgery with preoperative anemia will have higher composite morbidity and mortality rates (primary outcome), longer length of hospital stay, higher blood transfusion requirements and lower health-related quality of life (HRQoL) at 1, 3 and 6 months (secondary outcomes) when compared to elderly patients without preoperative anemia. The investigators will conduct a prospective observational study of 450 consecutive patients above 65 years, who are undergoing elective major open abdominal surgery in SGH over 12 months. Baseline clinical assessment, including iron studies for anemic patients, will be done within 14 days prior to surgery. To determine the primary outcome, patients will be followed up prospectively for 30 days from the day of surgery. This will be done via a mixture of medical records review and phone interview. For secondary outcomes, the length of hospital stay and readmissions for any reason within 3 and 6 months will be recorded. HRQoL questionnaires will be done through phone calls by a study team member. Findings from this study will hopefully fill the knowledge gaps such as how anemia impacts elderly people in terms of perioperative morbidity, mortality, postsurgical quality of life and their eventual return to the community as well as providing local data on the healthcare resource utilisation in this group.
