STAT3 hyper IgE syndrome (STAT3-HIES) is a primary immune deficiency syndrome characterized by elevated serum IgE, eczema, and recurrent skin and respiratory tract infections, together with several connective tissue and skeletal abnormalities.
Individuals with STAT3-HIES typically manifest in the newborn period with a rash, often diagnosed as eosinophilic pustulosis. The rash evolves into an eczematoid dermatitis that is often driven by staphylococcal infection .
Recurrent skin and sinopulmonary infections are noted in early childhood.

STAT3 function has not been fully characterized.
Hyper-IgE recurrent infection syndrome 1, autosomal dominant is caused by mutations in the STAT3 gene on chromosome 17.
No genotype-phenotype correlations for STAT3 missense pathogenic variants have been identified.

Intrafamilial variability is minimal and penetrance appears to be complete.

STAT3 hyper IgE syndrome (STAT3-HIES) should be suspected in individuals with the following findings:
Newborn rash and typically eczematous rash at least through childhood
Recurrent skin boils (often "cold," manifesting little inflammatory reaction)
Cyst-forming pneumonias
Mucocutaneous candidiasis
Nonimmune features such as three or more retained primary teeth, scoliosis, bone fractures following minimal trauma, hyperextensibility of joints, characteristic facial appearance, increased nasal width, high palate
Laboratory test results showing:
Elevations of serum concentration of immunoglobulin E (IgE) to levels above 2000 IU/mL (normal 100 IU/mL in adults);
Eosinophilia (700/L);
Diminished circulating memory T and B cells and near absence of IL-17-producing Th17 cells.

Biomarker and diagnostic research for hyper-IgE recurrent infection syndrome 1, autosomal dominant has been reported in the published literature.
No approved treatments are currently available for hyper-IgE recurrent infection syndrome 1, autosomal dominant. The disease remains an area of unmet medical need.
Evaluations Following Initial Diagnosis To establish the extent of disease in an individual diagnosed with STAT3 hyper IgE syndrome (STAT3-HIES), the evaluations summarized (if not performed as part of the evaluation that led to the diagnosis) are recommended. Table 3. Recommended Evaluations Following Initial Diagnosis in Individuals with STAT3 Hyper IgE Syndrome
System/Concern | Evaluation | Comment |
|---|---|---|
Skin | Dermatologic exam | Newborn rash eczema during childhood; often improves w/age |
Pulmonary | Chest imaging | Detection of bronchiectasis pneumatoceles |
Skeletal | Eval for scoliosis osteoporosis | Scoliosis typically progresses through adolescence.; Osteoporosis can be present in children adults; DXA screening recommended. |
Dental | Dental exam for possible retention of primary teeth | — |

DXA = dual-energy x-ray absorptiometry Currently, there is no complete cure or targeted treatment for STAT3-HIES. The mainstay of therapy is prevention of staphylococcal abscesses and pneumonias with prophylactic anti-staphylococcal antibiotics as well as early aggressive treatment of infections. |
Treatment of Manifestations in Individuals with STAT3 Hyper IgE Syndrome Manifestation/Concern | Treatment | Considerations/Other Eczema |
recurrent boils | Topical antiseptics, e.g., dilute bleach baths1 chlorhexidine; frequent swimming in chlorinated pool | Adequate skin lubrication is needed after bleach. Anti-staphylococcal prophylaxis, e.g., w/2x/day TMP/SMX |
pneumonias | Antibiotic prophylaxis, typically w/2x/day TMP/SMX | Targeting Staphylococcus aureus other pyogenic bacteria to prevent the pneumonias their complications In Coccidioides endemic regions use of prophylactic antifungals (e.g., fluconazole) can be considered. |
candidiasis | Antifungal prophylaxis | Consider fluconazole prophylaxis if living in a Coccidioides endemic region. Osteoporosis Minimal trauma |
fractures | Optimize calcium vitamin D intake | The role of bisphosphonates for those w/this disorder w/osteoporosis is unclear; some improvement seen in bone density but unclear improvement in fractures . Arterial |
aneurysms | Optimal blood pressure mgmt | Antiplatelet or anticoagulation therapies may be considered for individuals w/significant coronary artery aneurysms to prevent myocardial infarction related to clotting w/in the aneurysm. |
