Hyper IgE recurrent infection syndrome (HIES, or Job's syndrome) is a primary immunodeficiency characterized by recurrent skin and lung infections, eczema, elevated serum immunoglobulin E (IgE) levels, and various connective tissue and skeletal system abnormalities including characteristic facies, scoliosis, joint hyperextensibility, retained primary dentition, craniosynostosis, osteopenia, and pathologic fractures. We have identified two patients with aneurysmal coronary artery disease. One was a forty-three-year-old man with HIES and coronary artery aneurysms and ectasia identified on cardiac catheterization following myocardial infarction. The other was a 48-year-old man with coronary artery ectasia-aneurysm identified after cardiac catheterization for evaluation of chest pain. Although connective tissue abnormalities are common in HIES, this is the first report of coronary artery aneurysms in HIES. Further studies are necessary to determine the incidence, pathogenesis, and optimal therapy of these arterial abnormalities in HIES.

Hyper-IgE syndrome (HIES) is a primary immunodeficiency characterized by atopic manifestations and susceptibility to infections with extracellular bacteria and fungi, which frequently occur in the skin and lung. Atopic manifestations in HIES include extremely high serum IgE levels, eczema and eosinophilia. Most of the extracellular bacterial infections are associated with disproportionally milder inflammation than normal, which was originally described as having a 'cold abscess'. Non-immunological abnormalities are also observed in most patients with HIES, including a distinctive facial appearance, scoliosis, hyper-extensive joints and retained primary teeth. Recent studies have demonstrated that hypomorphic mutations in signal transducer and activator of transcription 3 result in the classical multisystem form of HIES, whereas a null mutation in tyrosine kinase 2 causes the autosomal recessive form of HIES that is associated with viral and mycobacterial infections. Analyses of cytokine responses in both types of HIES have revealed defects in signal transduction for multiple cytokines including IL-6 and IL-23, leading to impaired T(h)17 function. These results suggest that the defect in multiple cytokine signals is the molecular basis of the immunological and non-immunological abnormalities in HIES and that the susceptibility to infections with extracellular bacteria and fungi in HIES might be associated with the defect in T(h)17 cell differentiation.

Autosomal dominant Hyper-IgE syndrome (AD-HIES) is a rare primary immunodeficiency characterized by eczema, recurrent skin and lung infections, elevated serum IgE, and various connective tissue, skeletal, and vascular abnormalities. Mutations in signal transducer and activator of transcription 3 (STAT3) have recently been found to account for most cases; however, the pathogenesis of the varied features remains poorly defined. A distinct syndrome, known as autosomal recessive HIES (AR-HIES) manifests as severe eczema, recurrent bacterial and viral skin infections, and sinopulmonary infections. As opposed to STAT3 deficient HIES, AR-HIES lacks the connective tissue and skeletal manifestations but has an increase in neurologic abnormalities. In this review, we discuss the clinical presentations, genetic etiologies, and immunologic abnormalities of these two syndromes. In addition, we discuss animal models of STAT3 deficiency that provide insight into the pathogenesis of HIES. Further understanding of how STAT3 results in the diverse manifestations of HIES will allow us to develop more specific therapies for HIES as well as for many of the manifestations, such as scoliosis, recurrent staphylococcal infections, and eczema, which are common in the general population.

Hyper-IgE syndrome (HIES) is a complex primary immunodeficiency characterized by atopic dermatitis associated with extremely high serum IgE levels and susceptibility to infections with extracellular bacteria. Nonimmunological abnormalities, including a distinctive facial appearance, fracture following minor trauma, scoliosis, hyperextensive joints, and the retention of deciduous teeth are also observed in most patients. Recent studies have demonstrated that dominant-negative mutations in the signal transducer and activator of transcription 3 (STAT3) gene result in the classical multisystem form of HIES, whereas a null mutation in the tyrosine kinase 2 (TYK2) gene causes an autosomal recessive HIES associated with viral and mycobacterial infections. In both patients, signal transduction for multiple cytokines, including IL-6 and IL-23, was defective, resulting in impaired T(H)17 function. These findings suggest that the defect in cytokine signaling constitutes the molecular basis for the immunological and nonimmunological abnormalities observed in HIES.

The hyper-IgE syndrome (HIES) is a rare primary immunodeficiency characterized by a highly elevated serum IgE, recurrent staphylococcal skin abscesses and cyst-forming pneumonia. Non-immunological abnormalities, including a distinctive facial appearance, hyperextensive joints, scoliosis, fracture following minor trauma, and the retention of primary teeth are also observed in many patients. Recently, it was shown that heterozygous mutations in signal transducer and activator of transcription 3 (STAT3), can cause autosomal-dominant HIES. Here we identify and characterize a novel mutation in the DNA-binding domain of STAT3 in a patient with hyper-IgE syndrome. Sequence analysis revealed a de novo heterozygous transition of a G-to-A, causing a substitution of a glycine residue for an aspartic acid in the translated sequence (G342D). The patient has normal levels of STAT3, which is able to translocate to the nucleus upon IL-6 stimulation. However, enzyme-linked DNA-protein interaction analysis showed that the G342D mutation affects the binding ability of STAT3 to target DNA sequences. In addition, as shown by qRT-PCR, the mutation abrogates the STAT3-dependent transcription of the retinoid-related orphan receptor gammat (ROR gammat) gene, an indispensable transcription factor for the commitment of naive CD4+ T cells to the Th17 lineage. These data suggest that the novel G342D mutation affects the binding of STAT3 on DNA and the STAT3-dependent expression of ROR gammat mRNA, leading to the HIES phenotype.

Autosomal dominant HIES (AD-HIES) is a primary immunodeficiency caused by dominant negative mutations in STAT3 clustered in the DNA binding and SH2 domains. Although in vitro differences in mutational constructs are observed, clinical phenotypic correlates of these genetic changes have not been described. We reviewed the charts of 65 AD-HIES patients (DNA binding n=35; SH2 n=30), recorded the components of the NIH HIES clinical scoring system as well as brain and coronary artery abnormalities and analyzed data by mutation region in adults and children. Patients with SH2 domain mutations had increased frequency of high palate, broad inter-alar distance, upper respiratory tract infections and, in the pediatric sub-group, significant scoliosis. There was suggestion of increased mortality for patients with DNA binding mutations. Although subtle differences in phenotype were observed to depend on the STAT3 genotype, overall the clinical phenotypes were similar between individuals with DNA binding and SH2 domain mutations.

Cell proliferation has generally been considered dispensable for anteroposterior extension of embryonic axis during vertebrate gastrulation. Signal transducer and activator of transcription 3 (Stat3), a conserved controller of cell proliferation, survival and regeneration, is associated with human scoliosis, cancer and Hyper IgE Syndrome. Zebrafish Stat3 was proposed to govern convergence and extension gastrulation movements in part by promoting Wnt/Planar Cell Polarity (PCP) signaling, a conserved regulator of mediolaterally polarized cell behaviors. Here, using zebrafish stat3 null mutants and pharmacological tools, we demonstrate that cell proliferation contributes to anteroposterior embryonic axis extension. Zebrafish embryos lacking maternal and zygotic Stat3 expression exhibit normal convergence movements and planar cell polarity signaling, but transient axis elongation defect due to insufficient number of cells resulting largely from reduced cell proliferation and increased apoptosis. Pharmacologic inhibition of cell proliferation during gastrulation phenocopied axis elongation defects. Stat3 regulates cell proliferation and axis extension in part via upregulation of Cdc25a expression during oogenesis. Accordingly, restoring Cdc25a expression in stat3 mutants partially suppressed cell proliferation and gastrulation defects. During later development, stat3 mutant zebrafish exhibit stunted growth, scoliosis, excessive inflammation, and fail to thrive, affording a genetic tool to study Stat3 function in vertebrate development, regeneration, and disease.
