Lung function in hyper IgE syndrome

Area of Science:

• Pulmonology
• Immunology
• Genetics

Background:

• Hyper IgE syndrome (HIgES) is a primary immunodeficiency characterized by elevated IgE levels.
• Recurrent sinopulmonary infections are a hallmark of HIgES.
• Pneumatoceles and bronchiectasis are known but severe pulmonary sequelae.

Observation:

• A case of HIgES presenting with recurrent pneumonias from infancy.
• Progressive lung disease with development of pneumatoceles and bronchiectasis.
• Fatal outcome due to disseminated infection, with suspected allergic bronchopulmonary aspergillosis.

Findings:

• Sequential spirometric assessment was performed throughout the patient's clinical course.
• The study highlights the early onset and progression of respiratory infections and pulmonary sequelae.
• Early functional diagnosis and follow-up are critical for managing HIgES-related lung disease.

Implications:

• This case underscores the severe pulmonary manifestations of HIgES.
• Emphasizes the importance of early and consistent pulmonary function testing in HIgES patients.
• Highlights the need for comprehensive management strategies for lung complications in HIgES.
