Summary
Haemophilus influenzae was the most common cause of acute maxillary sinusitis in a European study. Streptococcus pneumoniae and Moraxella catarrhalis were also significant pathogens, highlighting the need for direct sinus aspiration for accurate bacteriology.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Medical Microbiology
Background:
- Acute maxillary sinusitis is a common condition often treated empirically.
- Bacteriological data is crucial for guiding appropriate antibiotic therapy.
- Previous studies have shown varying etiological patterns across different regions.
Purpose of the Study:
- To investigate the bacteriology of acute maxillary sinusitis across multiple European centers.
- To identify the most prevalent pathogens and their regional variations.
- To assess the prevalence of beta-lactamase producing strains.
Main Methods:
- A multicenter study involving 569 patients with acute maxillary sinusitis.
- Diagnosis confirmed by sinus radiography/ultrasonography and maxillary sinus puncture.
- Bacteriological analysis of sinus aspirates to identify causative pathogens.
Main Results:
- Pathogens were isolated from 66% of patients; 56% had a single pathogen, 10% had multiple.
- Haemophilus influenzae was the most frequent isolate (39.5%), followed by Streptococcus pneumoniae (17.9%) and Moraxella catarrhalis (7.7%).
- Regional variations observed, with H. influenzae more common in Finland, and S. aureus more prevalent in other European centers.
Conclusions:
- Haemophilus influenzae is a primary pathogen in acute maxillary sinusitis across Europe.
- Regional differences in pathogen prevalence and resistance patterns exist.
- Direct antral aspiration is recommended for reliable bacteriological diagnosis.
