Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Risk of developing clinical arthritis
To analyze the factors associated with the risk of developing clinical arthritis confirmed by ultrasound among exposures or combinations of exposures in patients at high risk of RA.
From the baseline to the end of the follow-up at 2 years
Secondary Outcomes (61)
Quantitative difference in Food Frequency Questionnaire (FFQ) between the 4 groups of subjects included, varying from never or rarely to daily or multiple times per day.
At baseline
Quantitative difference in National Observatory for Physical Activity and Sedentariness -Physical Activity Questionnaire (ONAPS-PAQ) expressed in MET (Metabolic Equivalent of Task) per week between the 4 groups of subjects included.
At baseline
Quantitative difference in patient-reported exposure outcome Alcohol and Substance Involvement Screening Test (ASSIST) score between the 4 groups of subjects included.
At baseline
Quantitative difference in Fagerström Test for Nicotine Dependence (FTND) score between the 4 groups of subjects included.
At baseline
Compare the exposure to pollution between the 4 groups of subjects included. "Exposure to pollution will be assessed by cross-referencing residential addresses with the Chimère database.
At baseline
- +56 more secondary outcomes
Study Arms (4)
Group 1
A total of 50 subjects will be recruited: individuals with ACPA≥2 N and clinically suspect arthralgia (CSA criteria ≥4) or those with ACPA≥N and rheumatoid factor≥2N along with clinically suspect arthralgia (CSA criteria ≥4). These subjects have an estimated 50% risk of progression to RA within 2 years.
Group 2
A total of 50 subjects will be recruited: individuals with ACPA≥2 N who do not meet the criteria for clinically suspect arthralgia (CSA criteria \<4) or those with ACPA≥N and rheumatoid factor≥2N who also do not meet the criteria for clinically suspect arthralgia (CSA criteria \<4). These subjects have an estimated 30% risk of progression to RA within 2 years.
Group 3
A total 25 subjects will be recruited: asymptomatic subjects (CSA criteria \<4) with a family history of RA in a first-degree relative (negative controls).
Group 4
A total of 25 subjects will be recruited: individuals with RA diagnosed at polyarthritis onset (diagnosis \<6 months) who have not yet been treated, with ACPA≥2 N or ACPA≥N and rheumatoid factor≥2N (positive controls).
Interventions
A total of 60 ml of blood will be collected while fasting, using the following tubes: one PAXGene Blood RNA Tube, one PAXGene Blood DNA Tube, five 5 mL serum tubes, five 5 mL EDTA tubes and one 2 mL EDTA tube for microbiota DNA analysis.
Urine will be collected, while fasting and after the administration of lactulose/ mannitol to assess intestinal permeability.
Stool samples will be collected either at the hospital or at home using a dedicated kit.
5 ml of saliva will be collected and saliva microbiome DNA will be collected using an OMNIgene Oral kit.
inhalation of salbutamol, measurement of peak expiratory flow by screening spirometry (15 min later), inhalation of a hypertonic aerosol for 3 periods of 7 min. At the end of each inhalation period, the induced sputum is collected and the peak expiratory flow is measured to prevent possible bronchospasms
To assess the risk of RA in high-risk subjects by evaluating for synovitis, tenosynovitis, or intermetatarsal-phalangeal bursitis.
MRI of the dominant or painful hand will be performed to assess the risk of RA in high-risk subjects.
Self-questionnaires will assess factors such as ethnic origin, family history of RA, diet, physical activity, exposure to toxic substances, pollution, occupational exposures, psychological and clinical factors.
Performed as part of routine care to assess dental health
The short-CTQ will be completed during this consultation, only in centers offering consultations with a psychologist.
The patient will wear a belt throughout the visit 1. At the end of the day, the heart rate variability data measured by the belt will be recorded in the CRF (RR interval, heart rate variability SDNN, RMSSD, and LF/HF sympathovagal balance).
Eligibility Criteria
The patients will be recruted during consultation or hospitalization.
You may qualify if:
- Age between 18 and 80 years old
- Group 1: Individuals with high risk of RA (ACPA ≥ 2N or ACPA ≥ N and rheumatoid factor ≥ 2N) and clinical signs of arthralgia (CSA criteria ≥ 4).
- Group 2: High-risk individuals (ACPA ≥ 2N or ACPA ≥ N and rheumatoid factor ≥ 2N) without clinical arthralgia (CSA criteria \< 4).
- Group 3: First-degree relatives of RA patients (no symptoms, negative controls).
- Group 4: Newly diagnosed untreated RA patients (ACPA ≥ 2N or ACPA ≥ N and rheumatoid factor ≥ 2N) (positive controls).
You may not qualify if:
- Groupe1-2-3:
- All groups:
- Taking current or past background treatment for RA, even for another indication
- Corticosteroid therapy ≥10 mg at baseline and in the previous week
- Presence of another connective tissue disease (Sjögren's, dermatomyositis, scleroderma, Sharp syndrome, etc.)
- Subject unable to read and/or write
- Inability to follow the patient during the study period
- Failure to obtain consent
- Non-affiliation to a social security scheme,
- Persons placed under legal protection, under curatorship or under guardianship
- Pregnant or breastfeeding women
- Person participating in another intervention research including an
