Trial summary

The relationship between exposure to air pollution and spondyloarthritis (SpA) has been poorly studied. Based on data from the literature on other inflammatory pathologies such as rheumatoid arthritis, we hypothesize that there is a relationship between exposure to air pollution and the risk of presenting a flare-up… Read more about this study

About this study

The relationship between exposure to air pollution and spondyloarthritis (SpA) has been poorly studied. Based on data from the literature on other inflammatory pathologies such as rheumatoid arthritis, we hypothesize that there is a relationship between exposure to air pollution and the risk of presenting a flare-up in SpA patients following and living in Franche-Comté (France).

Primary objective:The potential relationship between exposure to air pollution (nitrogen dioxide, fine particles with a diameter of less than 10 or 2.5 microns and Ozone) and the onset of a spondyloarthritis flare-up will be explored in patients with this pathology.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Assessment of exposure to air pollutionOther

    For each patient, exposure to air pollution will be assessed over a period immediately prior to any flare-up and over four periods at a distance from the flare-up.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Occurrence of a SpA flare-up

    The occurrence of a SpA flare-up measured by disease activity, defined according to the BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) and/or ASDAS-CRP (Ankylosing Spondylitis Disease Activity Score - C reactive protein) scores (BASDAI score ≥4/10 and/or ASDAS-CRP score ≥2.1) according to ASAS group

    Measured: 6 to 24 months

Questions about this trial

What is this clinical trial studying?

An observational study of Spondyloarthritis, Axial, run by Centre Hospitalier Universitaire de Besancon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Occurrence of a SpA flare-up (time frame: 6 to 24 months). 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 9 Jul 2025.
