Is this trial a fit for you?

Likely a good fit

Ideal candidates are newly diagnosed infants with classic cystic fibrosis who are not colonized with P. aeruginosa.

Probably not a fit

Patients who are already colonized with P. aeruginosa or have undergone grafting will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to assess the relevance of Porphyromonas as a biomarker for predicting the risk of P. aeruginosa colonization in children aged 0 to 18 years with cystic fibrosis. It is a monocentric study conducted in three phases: pre-inclusion, inclusion, and follow-up, with data and samples collected during routine clinical visits. The study will take place at the Roscoff CRCM, where clinical and paraclinical evaluations will be performed, along with annual dermatological and odontological follow-ups at the CHRU in Brest.

Why it matters

Potential benefit: If successful, this study could lead to improved early identification of children at risk for severe lung infections, enhancing their management and outcomes.

How similar studies have gone: While the approach of using biomarkers in cystic fibrosis is being explored, this specific study's focus on Porphyromonas is novel and has not been extensively tested.
