Purpose of Review
The aim of this review is as follows: (1) to present the role of otitis as a warning sign for inborn errors of immunity (IEI), (2) to establish which patients presenting otitis should be investigated for IEI, (3) to review data about main IEI associated with otitis-prone patients.
Recent Findings
Otitis media is a very common infection in general population. The concept of otitis-prone children established a certain frequency of the infections in order to look for conditions leading to them. The confirmation of middle ear impairment by specialists has demonstrated better confiability. The hallmarks for immunologic evaluation are the presence of complications as mastoiditis and membrane perforation, failure to thrive, and additional respiratory symptoms. Humoral immunodeficiencies have been more frequently described in association with otitis-prone patients, for example, hypogammaglobulinemia, MBL deficiency, and IEI associated with major syndromes.
Summary
Most of the patients with confirmed IEI present otitis as one of the recurrent infections. It is suggested the investigation of immune defects in patients with otitis, and the following warning signs are suggested: Otitis evolving with mastoiditis, abscesses, or systemic infections; no response to appropriate antibiotic therapy; otitis media associated with other infections; recurrent otitis leading to failure to thrive and general developmental delay; and family history of primary immunodeficiency and/or consanguinity.
