Detection of systemic autoimmune diseases in an ongoing assessment program for hand arthralgias. A comparative analysis with inflammatory and non-inflammatory arthropathies.

Introduction: Arthralgias are prevalent in systemic autoimmune rheumatic diseases (SARD), emphasizing the need for early recognition. This study aimed to estimate SARD frequency and compare clinical, laboratory, and imaging findings among SARD, non-inflammatory arthralgia (NIA), and RA in patients with hand arthralgias.

Methods: A prospective evaluation program included individuals aged ≥18 with hand arthralgias.

"Reuma-Check": Performance of a Comprehensive Fast-Track Program for the Diagnosis of Axial Spondyloarthritis in South America.

Objectives: The aim of this study was to evaluate the performance of a comprehensive diagnosis program called "Reuma-check" for the diagnosis of axial spondyloarthritis (SpA) in patients with low back pain (LBP).

Methods: This is a cross-sectional study. Patients with LBP aged 18 years or older were preselected, and those with at least 1 SpA feature completed the circuit.

EULAR definition of "arthralgia suspicious for progression to rheumatoid arthritis" in a large cohort of patients included in a program for rapid diagnosis: role of auto-antibodies and ultrasound.

Objectives: To evaluate the performance of the European League Against Rheumatism (EULAR) definition of arthralgias suspicious for progression to RA in patients with hand arthralgias and to estimate the added value of both auto-antibodies and ultrasound (US) with power Doppler (PD).

Methods: Consecutive patients admitted for hand arthralgias to "Reuma-check" ® program were included. This program includes the following at baseline: clinical assessment, laboratory tests, US with PD of both hands, and radiography of both hands and feet.
