What is

Hyper IgE syndrome

?

Hyper IgE syndrome (HIES) is also known as Job's syndrome. It is a primary immunodeficiency where recurrent skin boils, eczema and pneumonia are seen.

What are the

symptoms of Hyper IgE syndrome

?

Symptoms of Job's syndrome include eczema, recurrent abscesses, pneumonia and recurrent candida infections. Eczema usually occurs in the creases behind the ears, the back, buttocks and scalp. Boils and abscesses are commonly caused by bacteria called as staphylococcal aureus. Patients can also have recurrent sinusitis, otitis media, and ear infections. Pneumonia in patients with Hyper IgE syndrome leads to cavities in lung (pneumatoceles) or scarring of the lower air passages (bronchiectasis).

Adolescents have prominent forehead and chin, broad nose and thickened facial skin with lax joints. Fractures are common due to weak bones. Scoliosis (curved spine) is common. Primary teeth are retained for a longer time which in turn prevents eruption of the permanent teeth.

What is the

cause of Hyper IgE syndrome

?

Hyper IgE syndrome is rare with less than 850 cases reported worldwide. It affects both boys and girls equally. It is due to genetic mutation in the gene on chromosome 4. In some cases, the genetic mutation has not been identified.

Does Hyper IgE syndrome run in families?
There is a type of Hyper IgE syndrome which runs in families due to mutations in gene on chromosome 4. This kind of Hyper IgE syndrome is acquired by autosomal dominant inheritance whereby if one of the parent is affected, then chances of passing the abnormal gene to the child is about 50%.

How is the

diagnosis of Hyper IgE syndrome

made?

Measuring IgE levels is one of the laboratory test used for diagnosis of Hyper IgE syndrome. Usually, patients with Hyper IgE syndrome have levels above 2000 IU/ml. Presence of other clinical features such as boils, pneumonia, teeth abnormalities help to reach the diagnosis.

Elevated IgE levels may be seen in other conditions such as severe allergies and thus results must be interpreted with clinical features.

What is the

treatment of Hyper IgE syndrome

?

Skin care and prompt treatment of infections are essential. Eczema can be treated with moisturizing creams. Fungal infections can be treated with antifungals.

What are

complications of Hyper IgE syndrome

?

Patients with Jobs syndrome are at increased risk of certain types of cancers such as lymphoma or autoimmune diseases such as systemic lupus erythematosus (SLE).
