Rationale: Autosomal dominant mutations in STAT3 lead to HIES. Since HIES is a rare condition, it is difficult to study the characteristics of these patients.  Pneumonia with cavitation/abscess leading to pneumatoceles and secondary fungal infections are major causes of mortality and morbidity in patients with HIES.

Methods: We examined the clinical and biological findings of patients with HIES entered in USIDNET, focusing on patients with lung abscess.

Results: 85 patients, born between 1950 and 2013 were entered in USIDNET. 58.8% (50/85) were female and 41.1% (35/85) were male. 62.3% (53/85) were Caucasian, 15.3%(13/85) Hispanic or African American, 13% (11/85) Asian and 8% (7/85) were unknown.  54.2% (45/83) had family history of HIES. Mean age at diagnosis of HIES was 14 years (standard deviation: 13.9), mean IgE: 8,383.7mg/dL (standard deviation: 10,050). 72% (32/85) had skin abscesses, 40% (34/85) had retained teeth, 37.6% (32/85) had fractures and 33% (28/85) had scoliosis. 49.4% (42/85) had eosinophilia. 47.0% (40/85) were known to be on trimethoprim-sulfamethoxazole, 16.4% (14/85) on antifungal coverage, and 30.60% (26/85) on immunoglobulin replacement therapy. Pneumonias were attributed to Staphylococcus aureus (45.3%-24/53) or Aspergillus fumigatus (26.4%-14/53). 18.8% (16/85) had a history of lung abscess. Lung abscesses were associated with drug reactions (p[χ2]=0.01; OR: 4.03 [1.2-12.97), also with significantly more depression (p[Fisher's exact test]=0.036 and lower Karnofsky index scores (median [25th­75th percentiles]: 80 [70-90] versus 90 [80-100], p[Mann-Whitney]=0.007). 

Conclusions: Data from USIDNET provides a resource to examine the characteristics of patients with these rare diseases.
