Autoimmune hemolytic anemia (AIHA) is an immune-mediated disorder in which the body's own immune system attacks and destroys red blood cells. It can be a primary disorder or caused by an underlying condition. AIHA can be a recurrent condition, meaning that it can return after treatment or remission.
Risk Factors
There are several factors that can increase a person's risk of developing autoimmune hemolytic anemia. These include having certain autoimmune disorders, a history of blood transfusions, being of older age, and having certain infections. It is also more common in males than females.
Recurrence of AIHA
AIHA can recur after treatment or remission, although the exact cause is unknown. It is thought that some people may have a genetic predisposition to the condition. The recurrence can be triggered by a number of factors, including infections, medications, or other illnesses.
Managing Recurrence
When AIHA recurs, it is important to work with a doctor to determine the best treatment plan. Treatment may include medications to suppress the immune system, blood transfusions, or a stem cell transplant. In some cases, supportive care such as fluids and oxygen may be needed.
Prevention
There is no way to prevent the recurrence of autoimmune hemolytic anemia, but there are steps you can take to reduce your risk. These include avoiding infections, avoiding certain medications, and getting timely treatment for any underlying conditions. It is also important to follow your doctor's instructions and keep all of your follow-up appointments.
