• Recurrent staphylococcal abscesses,
sinopulmonary infections, and severe eczema
• Described in 1966; Job’s syndrome

• Not known incidence,
ranging 1:100,000-500,000

Pathogenesis
• Heterogeneous genetic origin; 2 forms
• AD-HIES:
– Signal transducer and activator of transcription 3 (STAT3), chromosome 17q21
• AR-HIES:
– Dedicator of cytokinesis 8 (DOCK8) • chromosome 9p24
– Tyrosine kinase 2 (TYK2) • chromosome 19p13.2

STAT3
• Signal transducers in many diverse pathways
• Many cytokines transmit signals through Jak-STAT pathways
– Bind to Jak proteins, STAT recruitment, phosphorylation, dimerizes, translocates to the nucleus, activation
• IL-6, IL-10, IL-21, IL-22, and IL-23
• Immunity, wound healing, angiogenesis, cancer

Hematopoietic stem cell
transplantation (HSCT)
• No any clinical benefit bone marrow
transplantation
• Successful immunologic reconstitution in
patients with both AD and AR-HIES esp.DOCK8
deficiency
• Should be early before development of life-
threatening complications, malignancies

• First report indicating HCT to be curative in
patients with AR-HIES
• Stable, full donor cell chimerism
• Exception of persistent low- IgA serum levels
and the exception of normal immune functions

• 2-year-old girl from consanguineous parents of Turkish
• HLA-matched related donor at 7 years of age
• 6 years after HSCT, alive and well and attending
regular school service
• No longer severe infections
• Still suffers from multiple food allergies (chocolate,
eggs, nuts) without respiratory or gastrointestinal
symptoms

Treatment
• IVIg
– Controversy
– Helpful in AD-HIES, difficult to control
infection despite prophylactic ATB

• IFN-γ therapy
– No clinical benefit
• Anti-IgE antibody (omalizumab)
– lack of data associating therapeutic benefits

IFN-γ therapy
• In vitro studies revealed an improvement in the
neutrophil chemotactic function with IFN-γ
• No clinical observations on IgE concentration
and on episodes of infection in patients with
HIES

Treatment
• H2-receptor antagonists: improve neutrophil
chemotactic function assessed in vitro
• Sodium cromoglycate: improve neutrophil
phagocytosis and in respiratory burst

Prognosis
• Infectious pulmonary complications appear
to be the leading cause of death, followed
by lymphoma
