Main Line Health treats people who have primary immunodeficiency diseases (PI)—a group of rare, chronic disorders in which part of the body’s immune system is missing or functions improperly.
Because one of the most important functions of the normal immune system is to protect us against infection, patients with a missing or improperly functioning immune systems, have an increased vulnerability to infections.
People with PI can face frequent health problems from recurrent or severe infections, and often develop serious and debilitating illnesses.
PI illnesses treated at Main Line Health include:
- X-Linked Agammaglobulinemia (XLA) – a rare inherited immunodeficiency in which the body is unable to produce the antibodies needed to defend against bacteria and viruses.
- Common Variable Immune Deficiency (CVID) – immunodeficiency diagnosed in adults aged 20 to 40, characterized by low levels of antibody function.
