Insights
Chronic adenoiditis often co-occurs with chronic rhinosinusitis (CRS) in children. This study found anaerobic bacteria predominantly in adenoid tissue, suggesting antibiotics targeting anaerobes may help manage adenoid hypertrophy and CRS.
Area of Science:
- Otolaryngology
- Pediatric Infectious Diseases
- Microbiology
Background:
- Chronic adenoiditis causing adenoid hypertrophy is prevalent in children.
- Co-existing chronic rhinosinusitis (CRS) is common, with adenoid infections hypothesized as a cause.
- Understanding the microbial landscape in adenoid hypertrophy and CRS is crucial for effective management.
Purpose of the Study:
- To investigate the microbiological profile of adenoid tissue and nasal swabs in children with adenoid hypertrophy and CRS.
- To explore potential microbial correlations between adenoid hypertrophy and CRS.
- To inform treatment strategies for pediatric adenoiditis and associated CRS.
Main Methods:
- A cross-sectional study involving 20 children diagnosed with CRS and adenoid hypertrophy.
- Aerobic, anaerobic, and fungal cultures of adenoid tissue.
- Aerobic and fungal cultures of nasal swabs from the middle meatus.
Main Results:
- Adenoid samples showed mixed flora with a predominance of anaerobic organisms (19/20).
- Nasal swabs revealed aerobic bacteria (7/20) and fungal organisms (2/20).
- A direct microbial correlation between adenoid hypertrophy and CRS was observed in only one case (MRSA).
Conclusions:
- The study highlights a significant presence of anaerobic bacteria within inflamed adenoid tissue.
- While a direct bacteriological link to CRS was not established, anaerobic predominance suggests their role.
- Inclusion of anaerobic-targeting antibiotics in medical management for these children is recommended to mitigate adenoid hypertrophy.
Abstract:
Chronic adenoiditis leading to adenoid hypertrophy is common in children. Many cases would also have co-existing chronic rhinosinusitis (CRS). Infact, long lasting bacterial infection of the adenoids has been hypothesized to be the cause for CRS in these children. A cross-sectional study was conducted in the departments of ENT and Micro-biology at Kasturba Hospital, Manipal, India between 2016 and 2017. 20 subjects who were diagnosed with CRS and adenoid hypertrophy took part in the study. Aerobic, anaerobic and fungal culture sensitivity of adenoid tissue was done along with aerobic and fungal culture sensitivity of nasal swabs from middle meatus. 2 out of 20 adenoid samples showed positive culture for aerobes and 19 adenoid samples grew anaerobic organisms. 7 out of 20 nasal swabs grew some aerobes and 2 were positive for fungal organisms. The correlation of microorganisms between adenoid hypertrophy and CRS was seen only in one patient in which methicillin resistant Staphylococcus aureus was grown. The present study showed mixed flora in the adenoid samples with anaerobic predominance. Aerobes were predominantly grown in nasal swabs from patients with CRS along with fungal colonizers. Though the study does not establish any bacteriological association with the CRS in our cohorts, the significant growth of the anaerobes from the core of the inflamed adenoids has prompted us to suggest the inclusion of the antibiotics against the anaerobes in the medical management of these children, whenever feasible. We think the addition of specific antibiotics to tackle anaerobes helps by hampering the further inflammatory hypertrophy of adenoid tissue.

Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
