What causes dysregulation of the immune system?
Immune dysregulation disorders (IDD) comprise a group of disorders that can be clinically and biologically distinguished from primary immunodeficiencies. They are caused by distinct genetic defects in immune regulatory pathways, some of which can also cause immunodeficiency.
What are examples of immune disorders?
Three common autoimmune diseases are:
- Type 1 diabetes. The immune system attacks the cells in the pancreas that make insulin.
- Rheumatoid arthritis. This type of arthritis causes swelling and deformities of the joints.
- Lupus. This disease that attacks body tissues, including the lungs, kidneys, and skin.
What happens when immune system overreact?
A: In many cases, an immune system that overreacts is as harmful and dangerous as one that stops working. In general, an overactive immune system leads to many autoimmune disorders — because of hyperactive immune responses your body can’t tell the difference between your healthy, normal cells and invaders.
How is immune dysregulation treated?
Treatment for immune dysregulation syndromes vary as much as the diseases themselves, and may include:
- Steroids.
- Immunomodulatory medications.
- Chemotherapy.
- Bone marrow transplant.
What happens when inflammation is dysregulated?
A successful outcome of inflammation is the elimination of the noxious stimuli and infection. A dysregulated inflammation can become harmful and healthy cells may be damaged. As a result, further inflammatory responses are activated, which can lead to organ failure and sepsis.
What is immune dysfunction?
Immune system disorders cause abnormally low activity or over activity of the immune system. In cases of immune system overactivity, the body attacks and damages its own tissues (autoimmune diseases). Immune deficiency diseases decrease the body’s ability to fight invaders, causing vulnerability to infections.
