Enthesopathy in rheumatoid arthritis and spondyloarthritis: An ultrasound study.

Objective: We aimed to compare the prevalence of enthesopathy seen on ultrasonography (US) in spondyloarthritis (SpA) and rheumatoid arthritis (RA) and compared it to healthy controls.

Methods: All included patients with RA (2010 ACR/EULAR criteria) and SpA (ASAS criteria) and healthy controls underwent clinical and US evaluation of enthesis at seven sites (quadriceps, proximal and distal patellar, Achilles and triceps tendons, plantar aponeurosis and lateral epicondyle enthesis). The Glasgow Ultrasound Enthesitis Scoring System (GUESS) and the Madrid Sonographic Enthesitis Index (MASEI) scores were determined by two sonographers blinded to clinical data.

Arthritis secondary to meningococcal disease: A case series of 7 patients.

Arthritis secondary to invasive meningococcemia is rare and has been described as a direct result of bacteremia or as immunoallergic-type arthritis, related to the immune complex. Only a few case series have been reported.This multicenter study aimed to describe the clinical characteristics and therapeutic outcomes of arthritis secondary to meningococcal infection.

Diagnostic delay in axial spondyloarthritis: A cross-sectional study of 432 patients.

Objectives: The diagnostic delay of axial spondyloarthritis (axSpA) is usually reported to be more than seven years but may have decreased recently. The objective was to quantify the diagnostic delay in patients with axSpA in France and to explore its associated factors.

Methods: Two cross-sectional observational studies included consecutively patients with axSpA (according to both ASAS criteria and rheumatologist expert opinion).
