Living with Hyper-IgE syndrome

A rare immune condition that causes high IgE levels, skin inflammation, and repeated skin and lung infections.

Understanding Hyper-IgE syndrome

Hyper-IgE syndrome is a rare immune system disease that affects how the body fights infections.

It causes high levels of immunoglobulin E (IgE), a type of antibody in the blood. People may have skin inflammation (dermatitis) and repeated infections of the skin and lungs.

Signs & symptoms

Symptoms vary from person to person. GARD's summary describes:

  • Skin inflammation (dermatitis)
  • Repeated skin infections
  • Repeated lung infections
  • High IgE levels in the blood

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include allergy and immune system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Autoimmune Association and Immune Deficiency Foundation may keep lists of experts for this condition.
