However, patients younger than 6 months of age may have very low to non-detectable IgE levels. An IgE level greater than 2,000 IU/mL is often considered diagnostic. TYK2 may present as HIES, although more often only with immunodeficiency.SPINK5 may present as HIES with skin and hair effects such as trichorrhexis invaginata (bamboo hair).PGM3, a Congenital Disorder of Glycosylation, may present as HIES with neurocognitive impairment and hypomyelination.Eczema is prominent, food and environmental allergies are common, and asthma and anaphylaxis has been variably reported. DOCK8 - DOCK8 Immunodeficiency Syndrome (DIDS) presents primarily with immune effects including HEIS.This altered pathway directly reduces the modulation capacity of interleukins 6 and 10 which, respectively, inhibit the genesis of Th17 cells that, in tandem with CD4 cells, protect against bacterial and fungal infections, and foster the inappropriate immune responses exhibited by those with Job Syndrome. The disease was linked to mutations in the STAT3 gene after cytokine profiles indicated alterations in the STAT3 pathway. A common mnemonic used to remember the symptoms is FATED: coarse or leonine facies, cold staph abscesses, retained primary teeth, increased Ig E, and dermatologic problems. STAT3 may present as HIES with characteristic facial, dental, and skeletal abnormalities that has been called Job's Syndrome.īoth autosomal dominant and recessive inheritance have been described: Pathophysiology Ībnormal neutrophil chemotaxis due to decreased production of interferon gamma by T lymphocytes is thought to cause the disease. Many patients with autosomal dominant STAT3 hyper-IgE syndrome have characteristic facial and dental abnormalities, fail to lose their primary teeth, and have two sets of teeth simultaneously. Inheritance can be autosomal dominant or autosomal recessive. It is characterized by recurrent " cold" staphylococcal infections (due to impaired recruitment of neutrophils), unusual eczema-like skin rashes, severe lung infections that result in pneumatoceles (balloon-like lesions that may be filled with air or pus or scar tissue) and very high (> 2000 IU/mL or 4800 mcg/L) concentrations of the serum antibody IgE. Job's is also very rare at about 300 cases currently in the literature. Hyperimmunoglobulinemia E syndrome ( HIES), of which the autosomal dominant form is called Job's syndrome or Buckley syndrome, is a heterogeneous group of immune disorders.
