National Cohort of Subjects at Risk of Developing Rheumatoid Arthritis
Source: ClinicalTrials.gov · Last updated 1 Oct 2026
Brief summary (registry, in English)
PROMESS 1 is a multicenter cohort interventional study aiming at analyzing the factors associated with the risk of developing clinical arthritis among exposures or combinations of exposures in patients at risk of rheumatoid arthritis (RA), as they have high levels of anti-citrullinated peptides autoantibodies (ACPA ≥2 N). The primary endpoint is the occurrence of clinical arthritis confirmed by ultrasound at two years of following for the subject's groups at risk of RA. This may be explained by the following exposures or combinations of exposures: smoking, occupational exposure, physical activity, diet, hormonal exposure, drug exposure, trauma and psychological stress. Other factors may also explain the occurrence of clinical arthritis: * Other symptoms * Comorbidities, medical history, drug exposures * Current biology: ACPA levels, rheumatoid factor levels and isotypes, CRP levels at baseline, etc. * Ultrasound and MRI abnormalities.
