Overview
Recurrent respiratory tract infections (RTIs) involve repeated infections of the upper and lower respiratory tract, often indicating underlying host defense deficiencies or structural abnormalities. 1Diagnosis
Ultrastructural analysis of bronchial cilia: Useful in identifying atypical cilia patterns indicative of impaired mucociliary clearance. 1
Exclusion of other conditions: Rule out Kartagener's syndrome, bronchiectasis, pneumonia, asthma, and cystic fibrosis through clinical evaluation and specific tests. 1
Ciliopathy assessment: Look for anomalies such as dynein arm defects, aberrant axonemal patterns, naked axonemes, and megacilia. 1Management
Address underlying causes: Target conditions like bronchiectasis or primary ciliary dyskinesia with specific interventions. 1
Antibiotics: For acute bacterial infections, use appropriate antibiotics based on culture and sensitivity results. 1
Supportive care: Include hydration, symptomatic relief, and respiratory physiotherapy to enhance mucociliary clearance. 1Special Populations
Pediatrics: Atypical cilia are noted in children with recurrent RTIs, suggesting acquired defects may play a role. 1
Comorbidities: Patients with bronchiectasis or suspected ciliopathies require specialized evaluation and management beyond standard RTI protocols. 1Key Recommendations
Perform ultrastructural analysis of bronchial cilia in children and adults with recurrent RTIs to identify potential ciliopathy contributing to impaired clearance. (Evidence: Moderate) 1
Exclude primary ciliary dyskinesia and other ciliopathies through detailed ciliary ultrastructural examination to guide specific management strategies. (Evidence: Moderate) 1
Tailor antibiotic therapy based on clinical suspicion and microbiological evidence rather than empirical broad-spectrum use in recurrent infections. (Evidence: Expert opinion) 1References
