Primary Immunodeficiency Primary immunodeficiency (PI) is a disorder that describes a group of
over 100 diseases
that: 2-4
- Have a wide range of symptoms
- Are caused by errors in the genes of the cells that make up the immune system
The
immune system is made up of organs, tissues, cells, and proteins that work
together to protect the body from many of the bacteria and viruses that
cause the infections that can make people sick. The immune system provides
protection by recognizing and helping the body destroy these bacteria and
viruses during an infection. When any part of a person's immune system is
missing or not functioning correctly, he or she may have PI. 2,3
While it's normal for people - especially kids- to get infections like colds, the flu, and ear or sinus infections, those with PI are at higher risk of getting infections. Their infections are usually more frequent, and can get very serious or take a long time to go away, even when treated with antibiotics. The infections may also keep coming back.
As a result, people with PI may have their quality of life, as well as their work, or school days, affected by illness.
