2025-09-16

Are frequent, severe infections a part of your life? Understanding Primary Immunodeficiency Diseases could be the key to finding answers and improving your health. Don't ignore the warning signs - discover what you need to know about these complex genetic conditions today.

What are the main causes of Primary Immunodeficiency Diseases?

  • These are inherited genetic disorders that impair immune system development and function, not diseases caused by lifestyle factors or environment.
  • There are many types of primary immunodeficiency, including agammaglobulinemia and selective IgA deficiency, each from a different genetic mutation.
  • These genetic defects can affect various immune cells, like T-cells and B-cells, or the proteins they produce to fight infection.

Key symptoms of Primary Immunodeficiency Diseases to watch for

  • The most common signs are recurrent, severe, or unusual infections that are very difficult to treat with standard antibiotic courses.
  • Other symptoms include poor growth, autoimmune disorders, and unexplained inflammation of internal organs without a clear infectious cause.
  • Specific types like Common Variable Immunodeficiency (CVID) or the severe SCID present with distinct patterns of infection and immune issues.

How can you manage Primary Immunodeficiency Diseases effectively?

  • A primary immunodeficiency diagnosis is confirmed through specialized blood tests that measure immune cells, their function, and genetic analysis.
  • Primary immunodeficiency treatment often involves lifelong immunoglobulin replacement therapy to provide antibodies the body cannot make on its own.
  • For severe types like SCID, treatment may involve a stem cell transplant; support is available from the Primary Immunodeficiency Foundation.
