Active clinical trials for "Anemia"

Autoimmune hemolytic anemia is characterized by shortened red blood cell survival and a positive Coombs test. The responsible autoantibodies may be either warm reactive or cold reactive. The rate of hemolysis and the severity of the anemia may vary from mild to severe and life-threatening. Diagnosis is made in the laboratory by the findings of anemia, reticulocytosis, a positive Coombs test, and specific serologic tests. The prognosis is generally good but renal failure and death sometimes occur, especially in cases mediated by drugs.

Hydroxyurea (HU) is approved by the United States Food and Drug Administration (FDA) to treat adults with sickle cell anemia. Hydroxyurea has also been tested and used with children with sickle cell anemia. However, there are not many studies describing the disposition of drug in children less than 5 years old. The FDA has requested this study to better understand how children ages 2 to 17 years with sickle anemia absorb and eliminate the drug (this is called pharmacokinetics). The investigators will measure how much Hydroxyurea (HU) gets into the bloodstream at different time points after taking this medication.

This study is a multi-site, retrospective chart review to determine the effect of Neevo® or Neevo®DHA (with higher folate and B12) versus standard prenatal vitamins on hemoglobin (Hgb) levels in pregnant women throughout the course of pregnancy. Neevo® is a prescription medical food indicated for the dietary management of women under a doctor's care who face high risk pregnancies, older overactive bladder (OB) patients and patients unable to fully metabolize folic acid. Data will be collected from existing patient charts of subjects administered Neevo® or Neevo®DHA daily compared to subjects administered a prenatal vitamin daily.

The investigators hypothesize that the post-hospitalized patient status is characterized by subacute and reversible metabolic and hematological changes that, if addressed and treated in a timely manner, would result in a reduced risk for repeat hospitalization. Consequently, a structured quality improvement program, focused on increasing adherence to company wide anemia management policies (ie hemoglobin monitoring within the first 3-5 days post-hospitalization, followed by an appropriate EPO dose modification within the 7 days post-hospitalization), will significantly decrease the risk of hospital re-admission in the 30 days after discharge.

The purpose of this study is to create a large Thailand database documenting the severity of anemia and its management in the cancer population.

RATIONALE: Collecting and storing samples of tumor tissue from patients with Fanconi anemia to test in the laboratory may help the study of cancer in the future. PURPOSE: This laboratory study is collecting and storing tumor tissue samples from patients with Fanconi anemia.

Background: Anemia in chronic heart failure (CHF) is directly linked to increased mortality and reduced exercise capacity. The pathomechanism for the development of anemia in CHF is not well understood. Impairment of iron homeostasis is discussed to be one of the major triggers in anemia of chronic disease. Hepcidin was recently described as the central regulator of iron homeostasis. Main hypothesis: Plasma hepcidin levels are altered in anemic CHF patients compared to non anemic controls and might be a main contributing factor of anemia in CHF. Iron regulator-hypothesis High levels of cytokines in CHF patients cause up-regulation of hepcidin, which in turn leads to low iron uptake causing anemia. In this case venous hepcidin and hemoglobin concentrations should both correlate with cytokine levels. Erythropoietin regulator-hypothesis Dysregulation of the erythropoietin system results in anemia, which represses hepcidin. This leads to a negative correlation between hemoglobin and hepcidin in plasma. Methods: 100 consecutive patients diagnosed with systolic CHF will be prospectively included in the study. Iron status will be assessed and hepcidin, erythropoietin as well as interleukin-1, interleukin-6 and soluble TNF alpha receptor levels will be measured by ELISA. Patients will be followed up for one year and mortality, rehospitalization and worsening of CHF will be documented.

The purpose of this study is to describe patient characteristics, treatment patterns, and clinical outcomes in adult patients with cancer who are receiving erythropoiesis-stimulating therapy (EST).

The risk of severe anemia is increased in patients treated by tri-therapy compared to patients treated by bitherapy. The underlying mechanisms involved in this toxicity remain unexplored but could also depend on the global exposure of telaprevir. The trough concentration or AUC of telaprevir could therefore be a predictive factor of the onset of anemia in patients treated by ribavirin/PEG-INF/telaprevir. The early measurement of telaprevir and ribavirin concentrations could help to manage HCV tri-therapy to improve tolerance and SVR.

This study looks at the causes of anemia in adults of all ages who are referred by their primary care physician.
