Patients with selective immunoglobulin A (IgA) deficiency can face a range of symptoms, from sinus and ear infections to bronchitis, pneumonia and even GI tract infections. But through treatment, education and support, we are here to guide them at every turn of their wellness journey. We understand the unique needs of patients, the concerns of their caregivers and the level of communication expected from prescribers. That’s why we help in any way we can by delivering immune globulin treatments on time and answering all questions. If cost is an issue, our funding team goes to work, looking for ways to provide patients with the medication they need. Along the way, we do whatever it takes to help make treatments a success.

Selective Immunoglobulin A Deficiency

One of the first steps after a selective immunoglobulin A (IgA) deficiency diagnosis is understanding the condition. The information on this site and linked sites is not meant to replace your physician’s advice, medical care or a diagnosis. If you have questions about your disease, please ask your prescriber.


Selective immunoglobulin A deficiency involves a weakening of the immune system rooted in the body’s B cells not being able to produce IgA, which protects the body’s mucous membranes (eyes, mouth, nose, etc.) from infection.

Most people with selective IgA deficiency are not likely to suffer any more infections than someone without the deficiency. That said, a wide range of health conditions are possible. Patients with IgA deficiency are most at risk of recurring ear, lung, sinus, and gastrointestinal infection. Other possibilities include allergies, asthma, autoimmune diseases (e.g., rheumatoid arthritis, celiac disease, etc.) and chronic diarrhea.
