Immunodeficiency Q & A

What is immunodeficiency?

Immune system problems fall into two broad categories: overactivity or underactivity. Allergies and autoimmune diseases are examples of an overactive immune system.

Immunodeficiency refers to an immune system that’s underactive or weak. This problem develops when key components of your immune system, such as white blood cells and specialized proteins, can’t fight off bacteria, viruses, toxins, and illness because they’re damaged or not functioning properly.

What types of immunodeficiency diseases might I develop?

Primary immunodeficiency diseases are directly caused by a problem with your immune system. There are more than 300 primary immunodeficiency diseases. Many are inherited but not diagnosed until late childhood or into adulthood. Getting a late diagnosis is common because it takes many years before an identifiable pattern of symptoms appears.

Secondary immunodeficiency diseases are caused by an underlying health condition that weakens your immune system. AIDS and viral hepatitis are two examples of secondary immunodeficiency diseases.

What symptoms develop due to an immunodeficiency?

The different immunodeficiency diseases each have their own set of symptoms. However, all immunodeficiency diseases make you vulnerable to infections. As a result, it’s common to have symptoms such as:

  • Frequent infections
  • Recurring sinusitis, ear infections, or pneumonia
  • Bronchitis or recurring lung infections
  • Swollen lymph nodes
  • Persistent skin abscesses
  • Nausea, cramping, diarrhea
  • Failure to grow in children

When you have an immunodeficiency disease, your respiratory symptoms may hide allergy symptoms, making it hard to get an accurate diagnosis. 

The best way to get to the source of your symptoms is with a thorough exam performed by Dr. Herrscher, who specializes in allergies and immunodeficiency diseases.

How is an immunodeficiency treated?

After diagnosing a primary immunodeficiency disease, most patients receive intravenous or subcutaneous gamma globulin. In many cases, you’ll need to keep getting this treatment for the rest of your life. 

Gamma globulin, also called immunoglobulin G, refers to a group of infection-fighting antibodies that are normally found in your bloodstream. When you have an immunodeficiency, however, your levels are low, so the first line of treatment is gamma globulin to boost your immune system and help you fight infections.

You may need additional treatment that targets the underlying disease or immune defect. For example, some patients benefit from bone marrow or stem cell transplants, while others need additional antibiotics for specific infections.

If you have frequent infections, call AIR Care or schedule an appointment for a thorough evaluation of your immune system.
