Warm reacting autoimmune hemolytic anemia (AIHA) is a rare type of anemia in which the body's immune system mistakenly attacks and destroys healthy red blood cells. It is caused by the production of autoantibodies, which are proteins that mistakenly attack the body's own red blood cells. AIHA can be either acquired or inherited, and can occur in people of any age.
Symptoms of Warm Reacting Autoimmune Hemolytic Anemia
The most common symptoms of AIHA include fatigue, shortness of breath, jaundice (yellowing of the skin and eyes), and dark urine. Other symptoms may include fever, weight loss, decreased appetite, and abdominal pain.
Diagnosis and Treatment of Warm Reacting Autoimmune Hemolytic Anemia
In order to diagnose AIHA, a doctor will perform a variety of tests, including a complete blood count (CBC) and a reticulocyte count. They may also use a Coombs test, which looks for antibodies on the surface of red blood cells. Treatment for AIHA may include corticosteroids, intravenous immunoglobulin (IVIG), and/or other medications. In some cases, a blood transfusion may be necessary.
Prevention of Warm Reacting Autoimmune Hemolytic Anemia
There is no known way to prevent AIHA, but it is important to avoid any triggers that may cause the condition to flare up. These triggers can include certain medications, infections, and stress.
