Insights
Persistent allergic rhinitis in children is significantly associated with otitis media with effusion (OME) and delayed mucociliary transport time. Middle ear effusion also showed higher eosinophil cationic protein (ECP) levels in persistent cases.
Area of Science:
- Pediatric Otolaryngology
- Allergy and Immunology
- Pediatric Respiratory Medicine
Background:
- The link between middle ear pathology and nasal allergies has been a long-standing debate.
- Otitis media with effusion (OME) is a common pediatric condition, and allergic rhinitis affects a significant portion of children.
- Understanding the interplay between these conditions is crucial for effective diagnosis and management.
Purpose of the Study:
- To investigate the relationship between otitis media with effusion (OME) and persistent allergic rhinitis symptoms compared to intermittent rhinitis in children.
- To evaluate specific clinical and immunological markers associated with OME in children with allergic rhinitis.
Main Methods:
- A cohort of 100 atopic children aged 5-9 years with otological symptoms underwent comprehensive ear, nose, and throat evaluations.
- Diagnostic tools included tympanometry, skin prick tests (SPTs) for allergens, mucociliary transport time (MCTt) measurements, and Eustachian tube function tests.
- Middle ear effusion analysis included eosinophil cationic protein (ECP) levels.
Main Results:
- Skin prick tests identified sensitization to common allergens like Dermatophagoides pteronyssinus, grass pollen, and Parietaria.
- A significant proportion of children experienced moderate to severe symptoms, with a notable number having persistent rhinitis.
- Delayed mucociliary transport time (MCTt) was observed in children with persistent rhinitis (21 ± 2 mins) compared to intermittent rhinitis (16 ± 2 mins) (P <0.01).
- Middle ear effusion was present in 45 children, and significantly elevated eosinophil cationic protein (ECP) levels were found in middle ear effusions (251 ± 175.2 μg/L) and blood (25.5 ± 16.3 μg/L) (P < 0.001).
Conclusions:
- A significant association exists between otitis media with effusion (OME), delayed mucociliary transport time, and elevated eosinophil cationic protein (ECP) levels in middle ear effusions of children with persistent allergic rhinitis.
- These findings suggest that the middle ear mucosa may act as a direct target organ in the pathophysiology of persistent allergic rhinitis in children.
Objectives:
The correlation between middle ear pathology and nasal allergy has been debated for almost 30 years. This study aimed to evaluate the relationship between otitis media with effusion (OME) and persistent allergic rhinitis symptoms versus intermittent rhinitis in children.
Methods:
The study included 100 atopic children (52 boys, 48 girls) aged 5-9 years with otological symptoms who were patients of the University of Siena Hospital, Italy. Ear, nose and throat evaluations, tympanometry, skin prick tests (SPTs), mucociliary transport time (MCTt) and Eustachian tube function tests were performed.
Results:
The SPTs revealed 50 children sensitised to Dermatophagoides pteronyssinus, 34 to grass pollen and 16 to Parietaria. Of all patients, mild symptoms were intermittent in 19 children and persistent in 18; moderate/severe symptoms were intermittent in 22 and persistent in 41. Tubal dysfunction was present in 25 children, whereas middle ear effusion was present in 45 children undergoing myringotomy. The MCTt was slower in the persistent group (21 ± 2 mins) versus the intermittent group (16 ± 2 mins) with a significant difference (P <0.01). Mean eosinophil cationic protein (ECP) values in the middle ear effusions of children who had undergone myringotomy were 251 ± 175.2 μg/L, and mean ECP blood values were 25.5 ± 16.3 μg/L, with significant differences (P < 0.001).
Conclusion:
There was a significant association between OME, delayed MCTt, ECP values in middle ear effusion and persistent symptoms of allergic rhinitis. These results suggest a direct involvement of the middle ear mucosa as a target organ in persistent forms.
