Clinical Trial Summary

The investigators will conduct a prospective observational study of non-invasive S. pneumoniae infections in Belgium and characterize serotype distributions to evaluate national vaccination programs.

Description:

The investigators will conduct a surveillance of non-invasive S. pneumoniae infections in Belgium (September 2020-May 2025). Monthly, 12 peripheral hospitals will send the first 15 unduplicated clinical S. pneumoniae samples (coming from patients diagnosed with pneumonia, otitits media or sinusitis) to the investigators. The investigators will determine the serotype and the antibiotic resistance profile of these clinical isolates. Whole genome sequencing will be performed on a subset of these isolates.

From May 2021, 13 extra participating centers have been added to the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Establish insight in serotype dynamics for non-invasive pneumococcal diseases in Belgium prospectively, in association with changing vaccination programs (campaigns).	There is a wealth of information available on the serotype distribution of S. pneumoniae causing inavsive pneumococcal disease (IPD). However, much less is known about the serotype distribution of S. pneumoniae causing non-invasive pneumococcal disease (NIPD). The goal of this study is to characterize the serotype distribution of of S. pneumoniae causing NIPD in Belgium, compare is with IPD data and link it with the changing national vaccinations programs.	September 2020-May 2025
Secondary	Surveillance of emerging serotypes, clones and drug resistances. Study of the genetic divergences between invasive and non-invasive pneumococcal diseases isolates.	To date, little is known about serotype distribution in NIPD and how this relate with the more widely studied serotype distribution in IPD. This study aims to shed light onto this topic.
