Primary immune deficiency (PID) is the name given to chronic illnesses caused by hereditary or genetic defects in the immune system. There are over 150 forms of PID. Some are mild, some are severe.
The immune system protects our bodies from germs such as bacteria and viruses that cause infections. People with PID do not have properly working immune systems. Often, they do not make enough antibodies, which fight off these germs. The result is infections that last a long time, frequently come back, and are hard to treat.
Here is a list of 10 warning signs of PID:
- Eight or more new ear infections within 1 year.
- Two or more serious sinus infections within 1 year.
- Two or more months on antibiotics with little effect.
- Two or more lung infections within 1 year.
- Failure of a baby to gain weight or grow normally.
- Deep skin or organ abscesses that keep coming back.
- Thrush in mouth or elsewhere on skin, after age 1, that won't get better.
- Need for intravenous (IV) antibiotics to clear infections.
- Two or more deep-seated infections.
- A family history of PID.
If your child has 2 or more of these signs, you should see your doctor about PID.
