Bronchi Dilation in Polynesian Patients: Monocentric Retrospective Study
An observational study of Polynesian Bronchiectasis, run by Centre Hospitalier Intercommunal Creteil at 1 site in French Polynesia.
Trial summary
The study hypothesis is that dilations of idiopathic bronchi are particularly common in French Polynesia, and that there are arguments in favour of an underlying genetic factor. The study will retrieve retrospective data in the history of bronchial dilation, patients' personal and family history, microbiological and… Read more about this study

About this study
The study hypothesis is that dilations of idiopathic bronchi are particularly common in French Polynesia, and that there are arguments in favour of an underlying genetic factor.
The study will retrieve retrospective data in the history of bronchial dilation, patients' personal and family history, microbiological and scannographic data, and the latest cardio respiratory checkup.

What is being measured
The primary outcome is the main question the study is designed to answer.
Describe the detailed phenotype of bronchi dilation in the Polynesian population
- Clinical criteria: age of onset, personal or family history, smoking Changes in respiratory function
- Infectious complications: types of bronchial colonization (bacterial, mycobacterial and mycological)
- Scantographic aspect: Appearance of bronchectasis: cylindrical, varicose orcious, cystic Distributions: LSD, LM, LID, LSG, LIG
Measured: Day 1
Secondary outcomes (1)
Highlighting indirect arguments for a genetic cause
Age of onset of symptoms, frequency of so-called "idiopathic" bronchi dilatation, frequency of inbreeding, familial history
Measured: Day 1

Questions about this trial
What is this clinical trial studying?
An observational study of Polynesian Bronchiectasis, run by Centre Hospitalier Intercommunal Creteil at 1 site in French Polynesia.

Where is the study taking place?
The record lists 1 site in French Polynesia. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Describe the detailed phenotype of bronchi dilation in the Polynesian population (time frame: Day 1). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jun 2026.
