2 chronic diseases of the immune system?

Answer 1

Probably the disease most commonly recognized as a disease of the immune system is Human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS), which is known as a secondary immune deficiency disorder (secondary = caused by something acting on the body, like the HIV virus that causes AIDS, as opposed to being primary = caused by inherited genetic mutations). There are many primary immune deficiency disorders, but these are less well-known, examples are: Severe Combined Immunodeficiency (SCID) and Selective Immunoglobulin A Deficiency.

Other diseases or disorders that affect the immune system are those that cause autoimmune diseases, such as Lupus Erythematosis, Rheumatoid Arthritis, Multiple Sclerosis, and Pernicious Anemia. These cause the the immune system to get confused and attack your cells as if they are foreign invaders to try to destroy the cells.

There are also medications that can affect the immune system to depress the immune response so that people with transplanted organs do not have the immune system attacking the "foreign" organ and creating "rejection".
