About Immunodeficiency Disorders

Overview

Symptoms

Diagnosis

Management

The immune system is made up of white blood cells, antibodies, and other specialized cells and proteins that work together to defend the body against bacteria, viruses, and parasites. Immunodeficiency disorders compromise your immune system, disrupting your body’s ability to fight off disease.

There are two types of immunodeficiency disorders:

  1. Primary Immunodeficiency
  2. Acquired Immunodeficiency

Immunodeficiency is usually noticed by a pattern of repeated infections that are unusually hard to cure. Infections may attack the skin, respiratory system, ears, brain, spinal cord, urinary tract, or gastrointestinal tract.

Primary Immunodeficiency Disorders

Primary immunodeficiency is hereditary or genetic, meaning that you are born with it. Primary immunodeficiency can target specific and/or multiple organs, glands, cells, and tissues, leading to a wide variety of different defects, such as heart defects, altered facial features, stunted growth, and autoimmune disorders like rheumatoid arthritis.

There are over 300 different primary immunodeficiency disorders. Specific primary immunodeficiency disorders include:

  • X-linked agammaglobulinemia (XLA)
  • Common variable immunodeficiency (CVID)
  • Severe combined immunodeficiency (SCID), also known as alymphocytosis

Acquired Immunodeficiency Disorders

Acquired immunodeficiency, also called secondary immunodeficiency, can occur when something weakens your immune system. Severe burns, malnutrition, HIV, and certain medications like chemotherapy or systemic steroids can cause acquired immunodeficiency. Acquired immunodeficiency disorders include:

  • AIDS (Acquired Immunodeficiency Syndrome)
  • Cancers of the immune system
  • Immune-complex diseases, like viral hepatitis
  • Multiple myeloma (cancer of the plasma cells, which produce antibodies)
  • Immunodeficiency Signs & Symptoms

    Recurrent infections are the most telling symptom of an immunodeficiency disorder. Other symptoms include:

    • Poor growth or loss of weight
    • Recurrent pneumonia, ear infections or sinusitis
    • Multiple courses of antibiotics or IV antibiotics necessary to clear infections
    • Recurrent deep abscesses of the organs or skin
    • A family history of primary immunodeficiency
    • Swollen lymph glands or an enlarged spleen
    • Autoimmune disease

    Serious primary immunodeficiency disorders typically become apparent in infancy, however, antibody deficiencies may present in older children or adults.

    Immunodeficiency Diagnosis

    Diagnosing an immunodeficiency disorder starts with seeing the right specialist. An immunologist has specialized training and expertise to diagnose and coordinate a management plan for immunodeficiency disorders.

    Blood Tests

    If your immunologist suspects an immunodeficiency disorder, blood tests are used to determine your white blood cell, T cell, and immunoglobulin counts. Abnormal numbers of certain cells can indicate an immune system defect.

    Prenatal Testing

    If you have a child with a primary immunodeficiency disorder, you may want to be tested for certain immunodeficiency disorders during future pregnancies. Prenatal testing is done by taking samples of amniotic fluid, blood or cells from tissue that will become the placenta; or testing for a genetic defect in DNA.

    Immunodeficiency Management

    Treatment for immunodeficiency disorders is targeted toward the specific immune defects, so the exact course of management varies from person to person. Treatments can include:

    • Bone marrow, stem cell, or thymus transplantation
    • Immunoglobulin (antibody) replacement
    • Gene therapy
    • Antibiotics to manage and prevent infections
    • Strategies to manage autoimmune disease
