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.
