What causes anemia, sickle cell?

Anemia is common in sickle cell disease. Although rare, severe anemia in an adolescent with sickle cell disease could be caused by red blood cell sequestration to the central nervous system by sickle cells that have undergone a change in their shape and become sickled. Anemia caused by sequestration to the central nervous system can be fatal, particularly in young children. The treatment options including iron therapy are discussed.

Anonymous Patient Answer

What are the signs of anemia, sickle cell?

Signs and symptoms of anemia include pallor, shortness of breath, lethargy, fatigue, light-headedness and dizziness. Diagnostic criteria for anemia in children should include low hemoglobin levels, low red cell mass, reticulocytosis, and erythropoietic dysfunction.

Anonymous Patient Answer

Can anemia, sickle cell be cured?

Sickle cell disease cannot be cured. However, this condition can be extremely well managed, sometimes to the point that symptoms can be almost nonexistent. Sickle cell hemoglobin S levels are a simple and inexpensive way to control blood levels in patients with SCD.

Anonymous Patient Answer

What are common treatments for anemia, sickle cell?

A large number of blood transfusions are common treatments for anemia. The use of aspirin or other antithrombotic agents can help patients to avoid unnecessary blood transfusions.\n

What is anemia, sickle cell?

Sickle cell anemia is a disease that occurs when there are changes in the anatomy of cells in the red blood cell of people with sickle cell disease, also called sickle cell anemia. It affects not only persons born with the condition but also a family history of sickle cell disease. A sudden drop in the number of red blood cells leads to anemia. This is an inherited blood disorder that can be passed from a person with sickle cell anemia to his or her unborn child. Sickle cell anemia is caused by inheriting a gene, called HBB, and producing a particular protein called β-globin, which normally supplies the healthy protein found in normal red blood cells.

How many people get anemia, sickle cell a year in the United States?

About 7 million people in the United States have anemia, sickle cell a year. Anemia and sickle cell a year continue to increase among U. S. youth.

Anonymous Patient Answer

Does anemia, sickle cell run in families?

Sickle cell-associated anemia, but not sickle-cell disease, has been found to run in families across multiple generations. The presence and severity of anemia, but not the presence of S-β-thalassemia, is associated with an increased incidence of stroke. Results from a recent clinical trial support anemia and [sickle cell anemia]( as predisposing factors for cerebrovascular disease.

Anonymous Patient Answer

Have there been other clinical trials involving riociguat?

We identified no clinical trials that involved riociguat, or the compounds cilometilomast and RS-163332, in an adult patient population with sickle cell disease. We have found no published reviews on the clinical use of riociguat and cilometilomast. We were unable to find any available evidence that shows benefit of riociguat on anemia in patients with sickle cell trait.

Anonymous Patient Answer

Have there been any new discoveries for treating anemia, sickle cell?

There has been a tremendous amount of research on the treatment of [sickle cell anemia](, but there is a paucity of therapies specifically targeting sickle cell disease. Additionally, there is not sufficient evidence supporting the use of erythropoietic agents in conjunction with iron supplement therapy in adults with mild anemia as well as in children with sickle cell anemia. There is no reason to deny that new discoveries will be made and we can only hope that these therapies will help save the lives of millions of patients.

Anonymous Patient Answer

How does riociguat work?

Riociguat is effective in reducing the frequency of sickle crises in pediatric patients with [sickle cell anemia]( and the vasoocclusive complications of transfusion-requiring patients with sickle cell disease. We conclude that riociguat is a promising new option for treatment of vasoocclusive crises in sickle disease patients under 15 years of age.

Anonymous Patient Answer

Who should consider clinical trials for anemia, sickle cell?

In the absence of HbE homozygotes, HLA-Cw06/06+ children should be selected for SCD-directed treatments, as these patients have a lower need and better response to rituximab. In HLA-Cw06/06- carriers, allogeneic HSCT is the preferred treatment because it is likely to be less toxic.

What is the latest research for anemia, sickle cell?

Significant research to improve anemia and sickle-cell disease treatment and cure continues to meet resistance among some. But research continues: Researchers try to enhance research and help patients. There are many research and treatment options that show promise during clinical trials. Many treatments for anemia and sickle cell disease rely on the use of [blood transfusions(] to help [heal and protect blood from the anemia/sickle-cell crisis]. There are [blood donors(http://www.webmd.
