Bone density and fractures in autosomal dominant hyper IgE syndrome.

Purpose: Autosomal Dominant Hyper IgE Recurrent Infection Syndrome (AD-HIES) is caused by mutations in STAT3 and characterized by eczema, recurrent bacterial infections, and skeletal and connective tissue abnormalities. To further understand the minimal trauma fractures of AD-HIES, we examined bone mineral density (BMD) and laboratory markers of bone turnover.

Methods: Patients with AD-HIES enrolled in a prospective natural history study were examined with dual x-ray absorptiometry (DEXA) scans and laboratory studies of bone metabolism.

Coronary artery aneurysms in patients with hyper IgE recurrent infection syndrome.

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.
