Relative etiological importance of adenoid hypertrophy versus sinusitis in children with persistent rhinorrhoea

Area of Science:

• Pediatrics
• Otolaryngology
• Infectious Diseases

Background:

• Persistent rhinorrhea is a common pediatric issue in India, often overlooked.
• The primary causes, adenoid hypertrophy and sinusitis, require further etiological investigation.
• The role of Streptococcus pneumoniae colonization in this condition is also unclear.

Purpose of the Study:

• To determine the relative importance of adenoid hypertrophy versus sinusitis in persistent rhinorrhea among children.
• To investigate the association between Streptococcus pneumoniae colonization and adenoid hypertrophy.
• To explore the potential link between nasal allergy and adenoid hypertrophy.

Main Methods:

• Clinical evaluation, rigid nasal endoscopy, and radiographic imaging (nasopharynx and paranasal sinuses) were used.
• Standard criteria were applied to diagnose adenoid hypertrophy and sinusitis.
• Nasopharyngeal swabs were collected to identify Streptococcus pneumoniae colonization.

Main Results:

• Adenoid hypertrophy showed a stronger association with persistent rhinorrhea than sinusitis (p < 0.0001).
• Co-existing adenoid hypertrophy and sinusitis were observed in 57% of cases.
• Streptococcus pneumoniae was cultured in only 29% of children, with no significant association with adenoid hypertrophy (p = 0.1).
• Nasal allergy features were present in 47% of patients, potentially contributing to adenoid hypertrophy.

Conclusions:

• Adenoid hypertrophy is a significant etiological factor in persistent rhinorrhea in children.
• Early assessment and management of adenoid hypertrophy are recommended.
• Streptococcus pneumoniae colonization is not a primary cause of persistent rhinorrhea in this population.
• Nasal allergy may play a role in the development of adenoid hypertrophy in approximately half of the affected children.
