To understand how PI can raise your risk of autoimmune diseases, it’s helpful to know a bit more about how the immune system works. In immunology, there is a concept called self-tolerance, which is the immune system’s ability to differentiate between its own cells and foreign bodies, such as bacteria. If self-tolerance fails, says Dr. Ballow, the body may attack its own healthy cells, which is known as autoimmunity. The immune system abnormalities in PI can cause these disruptions, potentially causing autoimmune disease.

Autoimmune problems can affect both children and adults with PI. They’re especially common in certain types of PI, including common variable immune deficiency, complement deficiencies, Good syndrome, hyper immunoglobulin M syndrome, idiopathic T cell lymphocytopenia, selective immunoglobulin A deficiency, and Wiskott-Aldrich syndrome.

While there’s no proven way to prevent autoimmune diseases in people with PI, staying proactive about your healthcare may make a difference. “We can’t really predict which patients will develop autoimmune disease,” says Ballow. “However, if we do genetic testing and we define a genetic abnormality … we can follow you a little more closely and perhaps catch an autoimmune process a little earlier.”
