Primary immunodeficiency

What is PI?

Primary immunodeficiency (PI) is also known as PID or PIDD (for primary immunodeficiency disorders, or diseases). It describes a group of more than 450 disorders that can affect a person’s immune system.

The immune system protects the body from bacteria and viruses. If it’s not working the way it should, a person will be more likely to get infections that are frequent or hard to treat.

The most common type of PI is selective immunoglobulin A (IgA) deficiency. Other types of PI include:

  • Common variable immune deficiency (CVID)
  • X-linked agammaglobulinemia (XLA)
  • Severe combined immunodeficiency (SCID)

PI symptoms

Frequent infections are one of the most common symptoms of PI. It can be difficult to diagnose a person with PI. Symptoms can vary and are easily mistaken for common infections.

The Immune Deficiency Foundation (IDF) recommends that people ask their healthcare provider to check for possible PI if they have an infection that is:

  • Severe - requires hospitalization or intravenous antibiotics
  • Persistent - won’t completely clear up or clears very slowly
  • Unusual - caused by an uncommon organism
  • Recurrent - keeps coming back
  • Running in the family - other family members have also been prone to infection

Living with PI

Along with working with your healthcare team and taking your prescribed treatment, there are a few things you can do to help prevent infection:

  • Wash your hands
  • Take care of your teeth
  • Start healthy habits like exercising, eating healthy, and getting a good night’s sleep
  • Try to stay away from crowds and people who are sick
  • Discuss vaccinations with your healthcare provider
