For example, exposure to body fluids infected with HIV or organ removal and replacement can both be causes.Īging can also weaken your immune system. People who have a family history of primary immunodeficiency disorders have a higher risk for developing primary disorders themselves.Īnything that weakens your immune system can lead to a secondary immunodeficiency disorder.

chronic conditions (like diabetes or cancer).

Secondary immunodeficiency disorders can be caused by a variety of things, including:

Primary immunodeficiency disorders are most commonly caused by inherited gene mutations. multiple myeloma (cancer of the plasma cells, which produce antibodies).immune-complex diseases, like viral hepatitis.cancers of the immune system, like leukemia.The following can cause a secondary immunodeficiency disorder:Įxamples of secondary immunodeficiency disorders include: Secondary immunodeficiency disorders happen when an outside source like a chemical or infection weakens your body. severe combined immunodeficiency (SCID), which is also known as alymphocytosis.common variable immunodeficiency (CVID).There are more than 200 primary immunodeficiency disorders.Įxamples of primary immunodeficiency disorders include: If you’re born with a deficiency from a genetic cause, it’s called primary immunodeficiency disease. What are the different types of immunodeficiency disorders?Īn immune deficiency disease or disorder occurs when the immune system is not working as expected. Your immune system can also be temporarily weakened by a stem cell or organ transplant.

This means your body can’t fight off infections or viruses as well as people who are not immunocompromised. If you have a weaker immune system, you’re immunocompromised. Certain T cells destroy foreign or atypical cells.Įxamples of antigens that your B and T cells might need to fight off include:Īn immunodeficiency disorder disrupts your body’s ability to defend itself against these antigens. B cells release antibodies specific to the disease your body detects. B and T cells fight invaders called antigens. These are white blood cells classified as B cells and T cells. These organs process and release lymphocytes. Your immune system includes the following organs:
