Hyper-IgE syndrome (Job's syndrome), first described in 1961, is a rare immunodeficiency disorder characterized by:
- extremely elevated IgE levels
- pneumonias which lead to pneumatoceles
- recurrent cold staphylococcal abscesses
- retained primary dentition
- and bone abnormalities
Many patients with autosomal dominant hyper-IgE syndrome (HIES) fail to lose their baby teeth and have two sets of teeth simultaneously. HIES was first described by Davis et al. in 1966 in two girls with chronic dermatitis, recurrent staphylococcal abscesses and pneumonias. They named the disease after the biblical character Job, whose body was covered with boils by Satan.
HIES inheritance is autosomal dominant but sporadic cases also occur.
A recent study published in the NEJM suggest that mutations in STAT3 underlie hyper-IgE immunodeficiency syndrome. STAT3 is an abbreviation for Signal Transducer and Activator of Transcription 3 gene (STAT3).
In conclusion, STAT3 mutations are a newly recognized genetic cause of hyper-IgE syndrome.
The discovery of the genetic cause will hopefully lead to better understanding of organ-specific infections and effective therapy in the future.
