Impact of Air Pollution on the Course of Inflammatory Rheumatism

France86 participantsStarted 2023-05-26

Plain-language summary

The objective of this study is to see if there is a link between air pollution and inflammatory rheumatism (rheumatoid arthritis and ankylosing spondylitis) To do this, the investigators are going to follow a cohort of about 200-400 patients for 6 months by means of a self-questionnaire, which the investigators ask the patient to fill in once a week on a fixed day, and opposite the corresponding week to put the letter corresponding to the question concerning the activity of your disease: 3 possible answers: A: no flare-up, B: short flare-up of 1 to 3 days, C: persistent flare-up of more than 3 days Then the investigators will collect the questionnaire at the end of these 6 months and at each visit to the consultation or day hospital (on average every 4 to 6 weeks), and they will look to see if any relapses have occurred. At the same time the investigators will calculate the disease activity score (DAS or BASDAI) to have an objective score. Then in parallel they will look at the level of exposure to air pollution according to the place of residence and work of each patient. The hypothesis is that air pollution has an influence on the activity of inflammatory rheumatism.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

Show that there is a difference in average exposure to regulated pollutants according to the occurrence or non-occurrence of inflammatory rheumatism (RA or APS).

Timeframe: Every week for 6 months
