Has been filed via the EU mutual recognition procedure [2]. Atgam is currently not licensed in the UK but is available on a named patient basis [3]. Atgam is composed of antibodies that bind a wide variety of proteins on the surface of lymphocytes. Atgam binds to granulocytes, platelets and bone marrow cells. Additional information. When used with cyclosporine , ATG improves blood counts in about 7 out of 10 cases.

If it works, ATG usually stops the need for blood transfusions within 3 months. Full success can take at least 9 months. Some patients may respond initially, but may later relapse and need another treatment. ATG is created injecting human white blood cells T cells into a horse or a rabbit, and extracting the antibodies produced. In other words, patients who took horse ATG had increased blood counts, and the counts stayed up longer when compared to patients given rabbit ATG.

Once the T-lymphocytes are turned off by the cyclosporine, they stop attacking stem cells in the bone marrow. In aplastic anemia patients, this allows bone marrow stem cells to grow back and start making blood cells again.

Cyclosporine is typically used in combination with ATG to treat acquired aplastic anemia. It is also used to prevent rejection after an organ transplant and to reduce immune response after a bone marrow transplant. Cyclosporine comes in liquid and pill forms. The first dose is based on how much you weigh. Later doses depend on the amount of cyclosporine in your blood. Too little cyclosporine will not work; too much will cause side effects. If you are responding well to cyclosporine, your doctor may decrease your dose over time.

When used alone, cyclosporine is less effective than ATG. When used with ATG, cyclosporine improves blood counts in about 7 out of 10 cases of acquired aplastic anemia. These problems can usually be fixed by taking medicine to lower your blood pressure and by replacing the lost magnesium or potassium.

Eltrombopag Promacta is used to increase the number of platelets cells that help blood clot and to decrease the risk of bleeding. It is a man-made platelet growth factor that signals your bone marrow to make more platelets. Eltrombopag was approved by the U. Food and Drug Administration in to treat refractory aplastic anemia. In , Eltrombopag was FDA approved as a first line therapy to treat aplastic anemia.
