It is importantto keep in mind the natural change in IgE levels over time: they usually areundetectable in cord blood and rise to the adult range slowly over the years.The normal IgE level is less than 130 IU per milliliter, as indicated by the dark shading; the mean (±SD) IgE levelsof patients with the hyper-IgE syndrome in this study are indicated by light shading.

Over the period of the last 8 years, we have collected a cohort of 228patientswith the suspected diagnosis of HIES in a worldwide collaboration; 55of these patients have been published elsewhere เหลือ173 เอามา 10072 patients came from Europe, 20 from theMiddle East, 7 from South America, and 1 from North America.>40 suggesting that these patientsprobably had HIES, 20 patients had scores below 40, suggesting adiagnostic uncertainty or a variant of HIES
31 distinct mutations46 patients carried previously described mutations,18 patients harbored distinct, novel mutations.Prospectively scoredthe 100 patients according to the NIH-HIES leave-1-out error estimates for all feature sets testedThere were 12 sets with a leave-1-out accuracy of 85%Of the 12 sets, 1 had 5 features,and 11sets had more than 5 featuresAControl: 11/12 > 1% of IL-17–producing CD41 T cellsSTAT3 mutation group: 13/17 had <0.5% of IL-17–producing CD4+T cellsSTAT3 WT group: 3/17 had <0.5% of IL-17–producing CD4+T cellsBSTAT3 mutation:signiﬁcantly lower frequencies of IFN-g–producing CD41 T cells than healthy controls ; had but signiﬁcantly higher frequencies than patients without STAT3 mutation (P 5 .007)STAT3 WT group: IFN-g–producing CD41 T cells < controls ;1 had >5% IFN-g–producing CD41 T cells.
None of the scores should be used tokeep physicians from pursuing a molecular diagnosis in aparticular patient. Patients with HIES accrue ﬁndings over time.-Aggressive treatment with antibiotics can forestall infectiouscomplications that would be diagnostic if allowed to occur.-Moreover, the unique feature of HIES that abscesses or otherinfections are ‘‘cold,’’ or not accompanied by a normal intensity ofpain or inﬂammation, has not been captured by any score, butshould increase clinical suspicion. -HIES scoring will not replacegood clinical judgment but may help the diagnostic process.- The aim of the proposed guidelines is to discern patients withHIES carrying mutations in STAT3 to facilitate time-saving andresource-saving diagnosis of patients, thereby leading to an earlyand effective treatment. -This screening tool will need to be evaluated and updated as new knowledge is revealed and new mutations causing HIES are identiﬁed. -We acknowledge that mostclinicians will continue to diagnose HIES with its key clinical features.-When itcomes to the question whether to evaluate STAT3, however, thisscoring should be used.
Before the association with heterozygous STAT3 mutationswas discovered, the diagnosis of AD-HIES depended on clinical findings and was often delayed until complications developed. NIHscoring system based on the presenceand severity of 21 clinical and laboratory findingshas beenwidely used to identify patients with HIES.

This patient (Subject II-3),1 who is now 50 years of age, has had lifelong eczema, multiple atraumatic fractures, hyperkeratotic fin-gernails owing to candida infection, recurrent Staphylococcus aureus abscesses, and pneumonia with lung abscesses and formation of pneumatoceles. She gave birth to three boys by two fathers. Her first son (Subject III-1) died 3 days after birth from pneumonia and sepsis with Pseudomo-nasaeruginosa and acinetobacter. Her second son (Subject III-3) was hospitalized shortly after birth with S. aureus pneumonia. Later, eczema developed, along with rising IgE levels (104,000 IU per milliliter in his second year of life [normal value, <64]), multiple skin abscesses, candidiasis, pneumonia with formation of pneumatoceles, and spontaneous rib factures; he also retained his primary teeth. At 28 years of age, he underwent lobectomy because of multiple pneumatoceles and persistent S. aureus and aspergillus infections. He died at the age of 29 years from respiratory failure. His 8-month-old son (Subject IV-1) was hospitalized at 3 months of age with failure to thrive, pneumothorax, S. aureus pneumonia with ab-scess formation, empyema, and multiple rib fractures. His current IgE level is 45 IU per milliliter (normal value, <15).

function as a GEF for the Rho-GTPases Cdc42and Rac1 active, GTP-bound form on receptor engagement (eg, receptor tyrosinekinases, antigen receptors, and adhesion receptors). An unknown protein possibly stabilizes theinteraction of DOCK8 with Cdc42 and Rac1.GTPase activation induces dynamic ﬁlamentousactinrearrangements and lamellipodia formation, possibly via WASP cell growth, migration, andadhesion. Given the clinical phenotype of the AR-HIES patients with DOCK8 deﬁciency, we propose animportant role of DOCK8 in T-cell actin dynamics, which might be important for the formation of the im-munologic synapse, leading to T-cell activation, proliferation, and differentiation.

7 patients had de novo STAT3 mutations. 17 had familial transmission of STAT3 mutations. 26 had sporadic STAT3 mutations. 1 of whom had chimerism for the STAT3 mutation. Mutational “hot spots” were apparent in DNA binding or SH2 domains. All mutations are missense or in-frame deletions, consistent with protein expression. Not find mutations in the 158 unaffected control subjects. Holland SM, et al. NEJM 2007; 357:1608-19.
STAT3 Mutations STAT3 is located on human chromosome 17q21. Ubiquitously expressed and not limited to immune cells. Predominantly missense and in-frame deletions. Normal STAT3 expression and trafficking to nucleus is observed, but effector functions of are abnormal. Mutations are located predominantly in the SH2, transactivation, and DNA binding regions. No clear correlations between phenotype and the affected region of STAT3. Heimall J, Freeman AF, Holland SM. Clin Rev Allerg Immunol 2010;38:32-8.

Immunophenotype & STAT3 mutationManifestations Possible mechanismsBone • Myeloid-specific STAT3-deficient mice have increased osteoclast numbers and activity. • Increase formation of osteoclasts & higher bone resorption activity of osteoclasts in HIES patients • Decreased IL-10 activity and increased TNF-α levelBrain • Astrocyte-specific STAT3 deficiency in mice led to increased inflammation and demyelination after neurologic injury • ? Disruption of IL-6 signaling in astrocyte differentiationHeart • Cardiac myocyte-specific STAT3 deficiency in mice is associated with decreased endothelial but increased fibroblast proliferation. • After stimulation with LPS, increased TNFα levels with subsequent cardiac inflammation.
