Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is an observational study that does not change routine care.

The primary objective of this study is to investigate the role of antibiogramme-antibiofilmogramme concordance (in terms of S. aureus strains and prescribed antibiotics) in the presence/absence of S. aureus strains at the end of a first regimen of antibiotics.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The secondary objectives are:

A. Should a first regimen of antibiotics fail, to describe the bacterial community present in the wound, and its potential to create biofilms.

B. To investigate the role of antibiogramme-antibiofilmogramme concordance (in terms of S. aureus strains and prescribed antibiotics) in wound healing.

C. To study the potential role of additional antibiofilmogramme data, as well as that of other pre-defined co-factors, in predicting wound changes.

D. Create an S. aureus strain collection for future ancillary studies.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Exposure: Concordance between tests

The study population is composed of diabetic patients with foot wounds (at least stage \>=2) that are infected by at least 1 strain of S. aureus. Patients whose antibiogrammes and Antibiofilmogrammes are concordant will fall into this group (the "exposed" group).

Upon inclusion, 1) all patients' wounds will be sampled, and 2) the associated bacterial strains identified via Vitek and 3) antibiograms performed; the latter are all part of routine procedure. 4) S. aureus isolates will be further analysed via an antiobiofilmogramme, which is an experimental element added by this research. At the end of the 1st regimen of antibiotics prescribed, if the treatment failed steps 1 to 4 can be repeated. 30 days after the end of the 1st regimen of antibiotics prescribed, steps 1 to 4 are systematically performed.

Group Type EXPERIMENTAL

Antibiofilmogramme

Intervention Type BIOLOGICAL

An Antibiofilmogramme (BioFilm Control) evaluates the capacity of a series of antibiotics to inhibit the growth of bacterial biofilms for a given bacterial isolate.

Non exposure: Not concordance between tests.

The study population is composed of diabetic patients with foot wounds (at least stage \>=2) that are infected by at least 1 strain of S. aureus. Patients who do not fall into the concordance (exposure) group, will fall into the non exposure group. The latter includes semi-concordance or discordance between antibiogrammes and Antiobiofilmogrammes.

Upon inclusion, 1) all patients' wounds will be sampled, and 2) the associated bacterial strains identified via Vitek and 3) antibiograms performed; the latter are all part of routine procedure. 4) S. aureus isolates will be further analysed via an antiobiofilmogramme, which is an experimental element added by this research. At the end of the 1st regimen of antibiotics prescribed, if the treatment failed steps 1 to 4 can be repeated. 30 days after the end of the 1st regimen of antibiotics prescribed, steps 1 to 4 are systematically performed.
