Active clinical trials for "Anemia"

Vaccines often underperform in Africa compared to high-income countries. Why vaccines do not work as well in Africa remains uncertain. Malnutrition likely plays a role. Our study objective is to assess whether iron deficiency anaemia in young women impairs their immune response to the COVID-19 vaccine, and whether iron treatment improves their response.

Real-CHOICE - designed as a prospective, longitudinal, observational, non-interventional study - will investigate the attitude of patients and physicians towards IV (intravenous) iron therapy in general and IIM (iron isomaltoside 1000) treatment particularly before and after IIM treatment in iron deficient patients with or without anemia in the real-world clinical setting after commercial availability of this product in Switzerland.

Study to Assess the Pharmacokinetics of GSK1278863A Coadministered with a High Fat Meal or an Inhibitor of CYP2C8 (gemfibrozil),]

The purpose of this study is to evaluate the safety and efficacy of intravenous iron sucrose in patients with hip fracture and surgical intervention to prevent perioperative anemia.

Postpartum anemia (PPA) and Postpartum depression (PPD) are common afflictions affecting women after childbirth. Both disorders have a significant impact on women's health and functional status. Despite common symptoms and characteristics, a link between these entities has not been adequately studied. The objective of this study is to determine whether postpartum anemia is an independent risk factor for the development of postpartum depression. This prospective cohort study will include all women delivered by elective term cesarean delivery. Hemoglobin and iron levels will be measured, standardized questionnaires for assessment of PPD, functional status and lactation will be administered before discharge and at 3 & 6 weeks post partum. Hemoglobin levels at each time point will be analyzed for correlation with depressive symptoms, functional status and lactation success.

Sickle cell anemia (SCA) is an inherited blood disorder that can cause organ damage. The BABY HUG study is evaluating the use of the medication hydroxyurea at preventing organ damage in children with SCA. The purpose of this follow-up study is to evaluate the long-term effects of hydroxyurea in children who have participated in the BABY HUG study.

The main purpose of this study is to evaluate the safety and efficacy (% response) of epoetin alfa in the treatment of anemia in adults receiving chemotherapy for cancer.

The study quantified functional measures of red blood cell mass and oxygen in neonatal tissues using a non-invasive optical technique: near infrared optical spectroscopy . The study will determine the absolute concentrations of deoxygenated and oxygenated hemoglobin and calculate the tissue hemoglobin saturation and total hemoglobin concentration in viv. Near infrared optical spectroscopy technique use to assessing and defining tissue status in the anemic state and the tissue's response to transfusions, as well as in monitoring hemoglobin and hematocrit without pain or loss of blood.

RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that did not respond to treatment may help doctors learn more about the disease and plan the best treatment. PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia that did not respond to treatment.

This study will collect samples of blood, stool, bone marrow, or other tissues from patients with hepatitis-associated aplastic anemia to investigate a possible association between exposure to viruses and the development of aplastic anemia in these patients. Cells from the samples obtained may be grown in the laboratory for future studies. Patients samples may be used to: Study abnormalities that occur in hepatitis-associated aplastic anemia; Test for various viruses; Test immune function; Measure factors related to the patients disease or diseases they may be at risk for; Evaluate the effectiveness of current therapies, refine treatment approaches, and identify potential new therapies; Identify possible measures for disease prevention; Identify possible genetic factors associated with hepatitis-associated aplastic anemia. Patients 2 years of age and older with severe aplastic anemia that developed within 6 months of an episode of hepatitis may be eligible for this study. Participants will complete questionnaires and provide tissue samples as described below. Questionnaires All patients (or another respondent for the patient) will fill out a questionnaire including demographic information (age, gender, race, ethnic group, education level, state of residence), current symptoms, medications, medical history, and history of possible exposures to toxins or viruses. A second questionnaire, which includes questions related to mental health, sexual behavior, alcohol and drug use, is optional for participants age 21 and older. These questionnaires are designed to uncover features of hepatitis-associated aplastic anemia and possibly reveal a common cause of the disease. Sample Collections Blood- will be collected at the time of the patient s initial evaluation or upon enrollment into the study and possibly periodically during the study. Blood will be drawn through a needle in an arm vein. Bone marrow- may be collected as part of the patient s standard medical care or specifically for research purposes of this study. For this procedure, the skin over the hipbone and the outer surface of the bone itself are numbed with an injection of a local anesthesia. Then, a larger needle is inserted into the hipbone and marrow is drawn into a syringe. Marrow cells are suctioned two to six times during the 15-minute procedure. Stool- will be provided by the patient. Liver- tissue may be biopsied as part of the patient s general medical care or for NIH patients, as part of their enrollment in a treatment protocol.
