Evaluate Pathogens and Immunity to Acute Otitis Media in Healthy Children. (AOM)

November 21, 2023 updated by: Michael Pichichero, Rochester General Hospital

A Study Evaluating Pathogens and Immunity to Acute Otitis Media and Nasopharyngeal Colonization in Healthy Children.

The purpose of this study is to Evaluate Pathogens and Immunity to Acute Otitis Media in Healthy Children.

Study Overview

Status

Active, not recruiting

Intervention / Treatment

Detailed Description

A prospective evaluation of bacterial pathogens Streptococcus. pneumoniae, Haemophilus influenzae, Moraxella. catarrhalis and Staphylococcus aureus and their antibiotic susceptibility when colonizing the nasopharynx and/or causing acute otitis media in the years 2015-2025. The goal will be to recruit children into a prospective group beginning at 6 months of age and followed to 36 months of age in suburban Rochester, New York. Nasopharyngeal and nasal wash samples will be obtained at each well child visit and at acute otitis media (AOM) episodes. Middle ear fluid will be obtained from every child with an acute otitis media episode who undergoes a tympanocentesis procedure. All of the nasopharyngeal and middle ear fluid samples collected will be tested by standard microbiologic techniques to identify the presence of 4 potential otopathogens (S. pneumoniae, H. influenzae, M. catarrhalis and S. aureus). All S. pneumoniae will undergo serotyping and antibiotic susceptibility testing. All samples that are culture negative will be evaluated with a multi-locus PCR test to examine for presence of potential otopathogens.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The distribution of bacteria causing acute otitis media.
Time Frame: 10 years
In this study, we are exploring the three main bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis) isolated from middle ear fluid samples (obtained by tympanocentesis) during acute otitis media episode in children ages 6-36 months.
10 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The distribution of potential otopathogens colonizing the nasopharynx.
Time Frame: 10 years
In this study we are exploring the three main bacteria (Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis) isolated from nasopharynx of children during their routine healthy visits at 6-36 months of age during an AOM episode.
