Objectives: The aim of this study was to describe the bacterial profile of middle ear fluid from spontaneous perforation of the tympanic membrane (SPTM) prior to widespread utilization of third- generation pneumococcal conjugate vaccines (PCVs).
Patients and methods: From October 2015 to January 2023, children with SPTM were prospectively enrolled by pediatricians.
Results: Among the 852 children with SPTM, 73.2% were less than 3 years old; more frequently than older children, they were and suffering from complex acute otitis media (AOM) (27.9%) and conjunctivitis (13.1%). In children under 3 years of age, NT Haemophilus influenzae (49.7%) was the main otopathogen isolated, particularly in those with complex AOM (57.1%). In children over 3 years of age, Group A Streptococcus accounted for 57%. In pneumococcal cases (25.1%), serotype 3 was the main serotype isolated (16.2%), followed by 23B (15.2%).
Conclusion: Our data from 2015 to 2023 represent a robust baseline preceding the widespread utilization of next-generation PCVs.
