Filter by:Anemia (decreased number of red blood cells) is common in critically ill trauma patients admitted to an Intensive Care Unit and is associated with a high rate of blood transfusions. This "anemia of inflammation" is a result of three mechanisms: impaired iron regulation, shortened red blood cell life span, and reduced rate of erythropoiesis (a protein that helps make new red blood cells). Hepcidin, a protein made in the liver, regulates iron and is decreased when iron in the blood is low. This can lead to anemia. This research study is being conducted to learn how inflammation, hepcidin, and erythropoietin interact in critically ill patients. The findings will help in determining effective treatment for patients with anemia of inflammation.
The purpose of this study is to determine whether Levamisole plus prednisone can further improve the efficacy，extend the remission duration and reduce the dosage of prednisone for newly diagnosed warm antibody autoimmune hemolytic anemia.
Background: - Anemia occurs commonly and is associated with poor outcomes in the elderly. In about a third of anemia cases in older people (over age 65), the cause of anemia is unexplained. Anemia in older adults may be caused by the bone marrow's inability to produce red blood cells fast enough to replace older red blood cells that have died. Researchers want to look at unexplained anemia by studying the life span of red blood cells in younger adults and older adults. To do so, a vitamin called Biotin will be used as a marker on the red blood cells. Objectives: - To investigate possible causes of unexplained anemia in older people. Eligibility: - Individuals in the following groups: - Men and women between 18 and 50 years of age who do not have anemia - Men and women at least 70 years of age who do not have anemia. - Men and women at least 70 years of age who have iron-deficiency anemia. - Men and women at least 70 years of age who have anemia with no known cause. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - Participants will have an overnight stay for the first study visit. They will provide a blood sample to which Biotin will be added. The blood sample with Biotin will then be returned to the participant. Twenty-four hours later, another blood sample will be collected. - Participants will have up to 14 additional study visits. At each visit, blood samples will be collected to measure the amount of Biotin remaining in the blood. - Participants may also provide a separate blood sample for genetic testing. These tests may provide more information about genetic causes of unexplained anemia.
Sickle cell disease (SCD) is an inherited blood disorder that causes the red blood cells to change their shape from a round shape to a half-moon/crescent or sickled shape. Sickle-shaped cells can cause problems by getting stuck in blood vessels, blocking blood flow, and can cause inflammation and injury to important body parts. There are no specific treatments that improve this condition and promote blood flow hindered by sickle cell blockages. Another big challenge in managing sickle cell disease is that there are no good measures to determine changes and improvements in blood flow. Contrast-enhanced ultrasound is a technique currently used to detect blood flow in the heart, muscles, and other organs. It is extremely sensitive and can detect blood flow in the smallest of blood vessels. It would be very useful in helping healthcare providers know whether treatment strategies are improving blood flow during sickle cell blockages. The hypothesis is that contrast-enhanced ultrasound will be a feasible tool for determining changes in blood flow of subjects with sickle cell disease.
The purpose of this study is to use comprehensive exercise testing to examine longitudinal changes in exercise capacity over a 2 year period in children and young adults with sickle cell anemia.
In this End Stage Renal Disease (ESRD) patients who need Erythropoietin (epo) hormone will get it by a small implant of skin using their own skin, the implant will be treated in the laboratory and programmed to secrete Epo. The implant secretes the patients own epo minimizing the need for injections for a period of up to 6 months.
SchistoVAN aims to study the role of schistosomiasis infection in the modulation of the immune response of children to childhood vaccine antigens, as well as the impact of this infection on their nutritional status and their haemoglobinaemia.
Background: - Some people with sickle cell disease have different health problems than others. This may be related to how easily and frequently the red blood cells break apart in the blood. Researchers want to test breath and blood samples from people with sickle cell disease to look for very small amounts of carbon monoxide, which is produced when red blood cells break apart. They will compare these results with breath samples from healthy volunteers. Studying different levels of carbon monoxide may help predict what health problems a person with sickle cell disease may get. It may also provide more information on possible treatments. Objectives: - To study breath carbon monoxide levels and their possible relation to the severity of sickle cell disease. Eligibility: - Individuals at least 18 years of age with sickle cell disease. - Healthy volunteers who are matched for age, sex, and race with the sickle cell disease group. Design: - Participants will be screened with a medical history. - Participants with sickle cell disease will provide a blood sample and have a heart function test. They will also breathe into a bag to provide an exhaled breath sample. - Healthy volunteers will provide an exhaled breath sample. - No treatment or care will be provided as part of this study.
Anemia is common among cancer patients and the treatment of choice is now Erythropoiesis-Stimulating Agents (ESAs). However, some patients do not respond to treatment. The purpose of this study is to evaluate the predictive value of endogenous erythropoietin rate on the response to erythropoietin beta. First, by confirming the predictive value of endogenous erythropoietin observed / predicted ratio on this response. Then if it is confirmed by establishing the optimal value of this ratio.
The purpose of this study is to estimate the incidence of Pure Red Cell Aplasia (PRCA), neutralising antibodies, lack of efficacy, and thromboembolic events under treatment with Retacrit™ (epoetin zeta) administered subcutaneously in patients with renal anaemia. The other key objective of this study is to obtain information on adverse drug reactions (ADR) associated with Retacrit™ (epoetin zeta), use of epoetin zeta during pregnancy and lactation and data on long term use.
