Evaluation of Bone Erosions in Rheumatoid Arthritis: The Ultrasound Score for Erosions Versus the Modified Sharp/van der Heijde Score for Erosions.

Objective: To evaluate the relationship between the UltraSound Score for Erosions (USSe) and the modified Sharp/van der Heijde score for erosions (SHSe).

Methods: One hundred eight patients with rheumatoid arthritis (RA) were included. On radiography, SHSe was evaluated by 2 or 3 blinded readers (in case of discordance).

ACPA-positive versus ACPA-negative rheumatoid arthritis: two distinct erosive disease entities on radiography and ultrasonography.

The objective of this study is to assess the prevalence, localization, and severity of bone erosions on radiography (RX) and ultrasonography (US) according to ACPA status in patients with rheumatoid arthritis (RA). 78 patients with ACPA-positive (ACPA+) RA and 30 patients with ACPA-negative (ACPA-) RA fulfilling the ACR 1987 and/or ACR/EULAR 2010 criteria were consecutively included. On RX, a modified Sharp erosion score (SHSe) was evaluated by two blinded readers and one adjudicator for discordant cases (number of eroded joints ≤ three).

Optimization of ultrasonographic examination for the diagnosis of erosive Rheumatoid Arthritis in comparison to erosive hand Osteoarthritis.

Objective: to determine thresholds and better scenario for the diagnosis of erosive rheumatoid arthritis (RA) by ultrasonography (US) in RA in comparison to osteoarthritic (OA) patients.

Methods: Patients, prospectively included, fulfilling ACR 1987; ACR/EULAR 2010 criteria for RA or hand OA criteria. Radiographic assessment (RX): Sharp erosion score, evaluated by two blinded readers and one adjudicator for discordant cases (number of eroded joints ≤ three).

Ultrasonographic criteria for the diagnosis of erosive rheumatoid arthritis using osteoarthritic patients as controls compared to validated radiographic criteria.

Objectives: The aims of this study were to compare characteristics of radiography (RX) and ultrasound (US) erosive lesions in rheumatoid arthritis (RA) and osteoarthritis (OA) patients (prevalence, topography and severity), to determine thresholds for the diagnosis of erosive RA based on US and to evaluate the performance of US and RX to establish a diagnosis of erosive RA differentiated from hand OA.

Methods: Patients fulfilling ACR 1987 and/or ACR/EULAR 2010 criteria for RA or ACR hand OA criteria were prospectively included. A modified Sharp erosion score was assessed by two blinded readers and one adjudicator for discordant cases (number of eroded joints ≤ three).

Multireader assessment as an alternative to reference assessment to improve the detection of radiographic progression in a large longitudinal cohort of rheumatoid arthritis (ESPOIR).

Introduction: Structural damage progression is a major outcome in rheumatoid arthritis (RA). Its evaluation and follow-up in trials should involve radiographic scoring by 1 or 2 readers (reference assessment), which is challenging in large longitudinal cohorts with multiple assessments.

Objectives: To compare the reproducibility of multireader and reference assessment to improve the feasibility of detecting radiographic progression in a large cohort of patients with early arthritis (ESPOIR).
