513 Hyper-IgE syndrome is a rare, hereditary multisystem disor- der characterized clinically by hyperimmuno-globulinemia E, recurrent infections, and eczematoid dermatitis. In 1966, Job reported two patients with eczematous dermatitis, recurrent staphylococcal boils, hyperextensible joints, and distinctive coarse facies. In 1972, Buckley et al. expanded the clinical picture by adding elevated immunoglobulin E (IgE).
GENETICS/BASIC DEFECTS
1. Inheritance:
a. Autosomal dominant with variable penetrance and expressivity
b. Linkage to a region on chromosome 4q demonstrated in several affected families
c. An up-regulating mutation in the interleukin-4 recep- tor gene on chromosome 16, demonstrated in some patients with hyper IgE syndrome
2. Etiology
a. The underlying cause of hyper IgE syndrome still unknown
b. Reduced neutrophil chemotaxis
c. Variable T cell defects demonstrated in some patients d. Cytokine and chemokine dysregulation
CLINICAL FEATURES
1. Classic triad (77%) a. Abscesses b. Pneumonia c. An elevated IgE 2. Skin manifestations
a. Onset with distinctive neonatal rash
i. Typically pruritic, secondary to intradermal mast cell histamine release triggered by the elevation of available IgE
ii. Often lichenified
iii. A distribution atypical for true atopic dermatitis b. Chronic eczema and dermatitis
c. Skin infections
i. Frequent presentation in infancy a) Furuncles
b) Occasional “Cold” abscesses c) Cellulitis
ii. Multiple staphylococcal abscesses on the skin (furunculosis)
a) Most common around the face b) Tender and warm to touch iii. Cold abscesses
a) A large fluctuant mass that feels like a tumor or cyst
b) Neither hot or tender
c) Not associated with systemic symptoms, fever or other signs of local or generalized inflammation
d) Filled with pus that always grows Staphylo- coccus aureus
e) Pathognomic to hyper IgE syndrome f) Not essential to the diagnosis d. Skin abscesses
e. Candidiasis 3. Infections
a. Pulmonary infections i. Recurrent and severe
ii. Most common infecting organism: Staphylo- coccus aureus
iii. Chronic infections a) Sinusitis
b) Discharging otitis media c) Otitis externa
d) Mastoiditis
iv. Long-term complications a) Bronchiectasis
b) Bronchopleural fistulae
c) Pneumatocele secondary to staphylococcal pneumonia
b. Mucocutaneous candidiasis and fungal infection i. Chronic candidiasis (83%)
a) Mucosa sites (oral moniliasis)
b) Nail fungal infection and dystrophy secondary to Candida albicans
ii. Aspergillus infection iii. Cryptococcal infection c. Other serious infections
i. Skin, sinopulmonary and bone infections: most common
ii. Staphylococcus: the most frequently infecting organisms
iii. Encapsulated organisms a) Haemophilus
b) Streptococcus pneumoniae
iv. Opportunistic infections: Pneumocystis carinii 4. Facial and dental abnormalities
a. Characteristic coarse facies i. Frontal bossing
ii. Wide alar base of the nose iii. Wide outer canthal distance
iv. Rare craniosynostosis v. Midline facial defects vi. High arched palate b. Red hair: uncommon finding
c. Retained primary teeth (72%): failure or delay of shedding of the primary teeth secondary to lack of root resorption

c. Perivascular dermatitis
GENETIC COUNSELING
1. Recurrence risk
a. Patient’s sib: not increased unless one of the parents is affected, in which case there will be 50% risk of sibling affected
b. Patient’s offspring: 50%
2. Prenatal diagnosis currently not available 3. Management
a. Antibiotics prophylaxis b. Dermatitis
i. Topical steroid ii. Topical antifungals iii. Emollient creams
c. Prompt treatment of infection with prolonged intra- venous antibiotics
d. Dental extraction of primary teeth
e. Surgical intervention by incision and drainage of abscesses
f. Chest tube drainage and lobectomy for complications of pneumonias
g. Orthopedic cares for fractures and scoliosis
h. Cimetidine, the histamine receptor-2 (H2) antagonist i. Shown to reverse the hyper-IgE syndrome neu-
trophil chemotactic defect in vitro
ii. A single patient showed a clinical improvement on treatment with improved neutrophil chemo- taxis in spite of a clinical relapse
iii. Another seven patients treated with H2 antago- nist with benefit
i. Cromoglycate tried in a single patient with good clinical effect
j. Isotretinoin used to improve dermatitis
k. High dose intravenous γ-globulin for patients with aberrant humoral immunity
l. Invasive approach with plasmapheresis with temporary improvement of skin condition and free of infections m. Bone marrow transplantation: only hope of cure at
present
n. A single report of a peripheral stem cell transplantation i. Serum IgE returned to normal
ii. Disappearance of symptoms
iii. Unfortunately, patient died of interstitial pneu- monia

Fig. 1. A 3 year 9 month old patient with hyperimmunoglobulin E syn- drome showing bowing of the legs. He had history of recurrent pneu- monias, otitis media, asthma, and fractures of the leg bones. At 2 year 10 month of age, IgE was 15,610 (≤93 KU/L). He is currently on intra- venous immunoglobulin therapy with antibiotic prophylaxis.
