Factors of ILD in Newly Diagnosed Rheumatoid Arthritis

To determine factors associated with early RA-ILD (which may be asymptomatic). It is planned to recruit all patients with a newly diagnosed RA (symptoms since less than 3 years). In this study, all relevant demographic and clinical data will be collected. All patients will undergo lung function tests and high-resolution CT-scan of the lungs. Blood sample will be collected for measurement of (1) anti-CCP and rheumatoid factor measurement (good clinical practice) and a specific sample for the detection of the MUC5 promoter variant rs35705950. Our aim is thus to identify determinants of RA-ILD in the following population: - Adults aged 18 to 90 years-old - Diagnosis of rheumatoid arthritis (RA) based on ACR-EULAR 2010 criteria - Onset of disease duration at least 1 year and at most 10 years prior to inclusion

NCT04002765 Rheumatoid Arthritis
MeSH: Arthritis Arthritis, Rheumatoid
HPO: Arthritis Polyarticular arthritis Rheumatoid arthritis

1 Interventions

Name: pulmonary function tests

Description: Lung function tests (standard of care) Dynamic and static volumes (FVC, FEV1, TPC, RV) Lung diffusion capacity for CO (DLCO) Chest Xrays High resolution CT scanner (HRCT)

Type: Diagnostic Test

New RA patients


Primary Outcomes

Description: Detection of an interstitial lung disease associated with RA. We define RA-ILD by the presence of reticulations, ground-glass opacity and/or honeycombing at HRCT not explained by another cause (i.e. cardiac disease, infection or neoplasia).

Measure: Presence of an interstitial lung disease

Time: from enrollment of patient to 3 months post enrollment

Secondary Outcomes

Description: usual interstitial pneumonia, non-specific interstitial pneumonia, others

Measure: Proportion of different ILD subtypes

Time: from enrollment of patient to 3 months post enrollment

Description: Non-ILD lung involvement is a composite of the following variables: rheumatoid nodules, emphysema, bronchiectasis and bronchiolitis obliterans

Measure: Proportion of patients presenting with a non-ILD lung involvement of RA

Time: from enrollment of patient to 3 months post enrollment

Description: Proportion of patients carrying the variant rs35705950 of the MUC5B promoter

Measure: rs35705950 variant of the MUC5B promoter

Time: from enrollment of patient to 3 months post enrollment

Description: Proportion of patients with anti-CCP antibodies

Measure: anti-CCP antibodies

Time: from enrollment of patient to 3 months post enrollment

Description: Proportion of patients with a relevant toxic exposure (smoking, drug, occupational or domestic exposure)

Measure: relevant exposure

Time: from enrollment of patient to 3 months post enrollment

Purpose: Diagnostic

1 rs35705950

Blood sample will be collected for measurement of (1) anti-CCP and rheumatoid factor measurement (good clinical practice) and a specific sample for the detection of the MUC5 promoter variant rs35705950.

rs35705950 variant of the MUC5B promoter.

Proportion of patients carrying the variant rs35705950 of the MUC5B promoter.

Detection of the rs35705950 variant for MUC5B promoter Lung assessment (SOC) 1. Lung function tests (standard of care) 1. Dynamic and static volumes (FVC, FEV1, TPC, RV) 2. Lung diffusion capacity for CO (DLCO) 2. Chest Xrays 3. High resolution CT scanner (HRCT) 1. Good clinical practice (INAMI/RIZIV) 2. Including expiratory slices (detection of early air trapping) Primary outcome Detection of an interstitial lung disease associated with RA.

Secondary outcomes 1. Proportion of different ILD subtypes (usual interstitial pneumonia, non-specific interstitial pneumonia, others) 2. Detection of non-ILD lung involvement of RA including: - Rheumatoid nodules - Emphysema - Bronchiectasis not related to an ILD - Bronchiolitis obliterans 3. Proportion of patients carrying the variant rs35705950 of the MUC5B promoter 4. Proportion of patients with anti-CCP antibodies 5. Proportion of patients with a relevant toxic exposure (smoking, drug, occupational or domestic exposure) 4.4 Expected timeline Start of recruitment: 01-July-2019 End of recruitment: 31-Dec-2022 Based on our local recruitment of RA patients, it is expect to recruit 300 patients.
