Impact of the Persistence of Inflammation at Doppler Ultrasound Level on the Structural Evolution of Erosion in Rheumatoid Arthritis Treated With Biotherapy
- Conditions
- Rheumatoid Arthritis
- Interventions
- Device: HR-pQCT
- Registration Number
- NCT02531061
- Brief Summary
Since biological disease-modifying anti-rheumatic drugs (bDMARDs) are available in rheumatoid arthritis (RA) strategy an emerging question is the definition of remission in RA. Today some criteria were already proposed and the last one was proposed in 2011.
All these criteria integrated only clinical criteria without imaging assessment. In this context, ultrasound joint is daily performed without definition of remission. A discrepancy exists between clinical remission and persistence of active disease with ultrasound joint presence of a Doppler effect indicating inflammation and the risk of progression of joint damage. A definition of remission in RA could include erosions regression in subchondral bone (at best measured by high resolution peripheral quantitative computed tomography (HR-pQCT)).
The main hypothesis is that the reduction of erosion size assessed by HR-pQCT will be observed only in the absence of local inflammation measured by Doppler ultrasound in the erosion.
Tumor Necrosis Factor (TNF) blockers have strongly improved RA therapy outcome in terms of clinical improvement and structural damage (progression of radiographic lesions). Recent data showed that there could be joint bone rebuilt in case of inflammation suppression. HR-pQCT is a new technique emerging for bone erosions assessment in RA. Erosions size and volume could be reduced with anti-TNF, but with a large interindividual variability. There was no correlation between the activity of clinical or ultrasound synovium and evolution of erosion HR-pQCT.

Group Intervention Description inactive erosion HR-pQCT HR-pQCT for measure bone parameters in "active erosion" group. The "inactive erosion" group will be defined by grades 0 and 1, ie the absence of Doppler signal for grade 0 and the presence of some non confluence Doppler signals for the grade 1 active erosion HR-pQCT HR-pQCT for measure bone parameters in "active erosion" group. The "active erosion" group will be defined by grades 2 and 3, ie by the presence of Doppler signals confluence in less than 50% of the synovial surface (grade 2) and in over 50% of the surface synovial for grade 3
- Primary Outcome Measures
Name Time Method Change in depth of the erosion baseline from 1 year compare the change in the depth of the erosion of the second or third metacarpal head right or left at 12 months between patients with "active erosion" and those with "inactive erosion" in RA patients with low disease activity treated with bDMARD since at least 6 months (Remicade®, Enbrel®, Humira®, Cimzia®, Simponi®, Ro-Actemra®, or Orencia®).
- Secondary Outcome Measures
Name Time Method Change in width of erosion baseline from 1 year compare the change in width of erosion of the second or third metacarpal head right or left at 12 months between patients with "active erosion" and those with "inactive erosion" in RA patients with low disease activity treated with bDMARD since at least 6 months (Remicade®, Enbrel®, Humira®, Cimzia®, Simponi®, Ro-Actemra®, or Orencia®).
Change in density parameter of bone microarchitecture baseline from 1 year compare the change in density parameter of bone microarchitecture of erosion of the second or third metacarpal head right or left at 12 months between patients with "active erosion" and those with "inactive erosion" in RA patients with low disease activity treated with bDMARD since at least 6 months (Remicade®, Enbrel®, Humira®, Cimzia®, Simponi®, Ro-Actemra®, or Orencia®). Density parameter of bone microarchitecture is a composite outcome : Total mineral volumetric density (mg/ccm HA), Trabéculaire mineral volumetric density (mg/ccm HA), Cortical mineral volumetric density (mg/ccm HA), Trabecular Number (1/mm), Trabecular thickness (mm), Trabecular Separation (mm), Mean distance between trabeculae (mm), Presence of new erosions and volume
Change in volume of erosion baseline from 1 year compare the change in volume of erosion of the second or third metacarpal head right or left at 12 months between patients with "active erosion" and those with "inactive erosion" in RA patients with low disease activity treated with bDMARD since at least 6 months (Remicade®, Enbrel®, Humira®, Cimzia®, Simponi®, Ro-Actemra®, or Orencia®).
