Otitis Media and Inborn Errors of Immunity.

Area of Science:

• Pediatrics
• Immunology
• Otolaryngology

Background:

• Otitis media is a frequent infection, with 'otitis-prone' children requiring further investigation.
• Specialist confirmation of middle ear issues improves diagnostic reliability.
• Key indicators for immunologic evaluation include complications, failure to thrive, and respiratory symptoms.

Purpose of the Study:

• To highlight otitis as a potential warning sign for inborn errors of immunity (IEI).
• To define criteria for investigating otitis patients for IEI.
• To review IEI commonly associated with recurrent otitis.

Main Methods:

• Literature review focusing on otitis and inborn errors of immunity.
• Analysis of warning signs and diagnostic hallmarks for immunologic evaluation.
• Identification of IEI frequently seen in otitis-prone individuals.

Main Results:

• Humoral immunodeficiencies are common in otitis-prone patients (e.g., hypogammaglobulinemia, MBL deficiency).
• Otitis is a recurrent infection in most patients with confirmed IEI.
• Specific warning signs warrant immune defect investigation: mastoiditis, systemic infections, antibiotic resistance, associated infections, failure to thrive, developmental delay, and family history.

Conclusions:

• Investigating immune defects in patients with recurrent otitis is recommended.
• Early identification of IEI through otitis warning signs can improve patient outcomes.
• Understanding the link between otitis and IEI is vital for comprehensive patient care.
