Similarities and differences between systemic juvenile idiopathic arthritis and adult-onset Still's disease: a multicenter Spanish study.

To describe the characteristics of systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD), compare their presentation and evolution, and analyse possible complication predictors. Multicenter study. Data were retrieved from a hospital-based study of patients with a diagnosis or suspected diagnosis of sJIA or AOSD according to the responsible physician and followed-up for at least one year.

F-FDG positron emission tomography as a marker of disease activity and treatment response in ankylosing spondylitis and psoriatic arthritis.

The ability of F-FDG positron emission tomography (PET) to track disease activity and treatment response in patients with Ankylosing Spondylitis (AS) or Psoriatic Arthritis (PsA) remains unclear. Here, we assessed whether F-FDG uptake is a marker of disease activity and treatment response in AS or PsA, and explored the ability of F-FDG to predict treatment response. Patients with AS (n = 16) or PsA (n = 8) who were scheduled to initiate treatment with biologics were recruited.

Subcutaneous vs intravenous abatacept in rheumatoid arthritis-interstitial lung disease. National multicentre study of 397 patients.

Background: Evidence on abatacept (ABA) utility for rheumatoid arthritis (RA) - associated interstitial lung disease (ILD) is growing. Clinical trials have shown equivalence in subcutaneous (SC) and intravenous (IV) administration of ABA for articular manifestations. However, this has not been studied in respiratory outcomes.

Interleukin-17-targeted treatment in patients with spondyloarthritis and associated cardiometabolic risk profile.

Spondyloarthritis is a group of immune-mediated rheumatic disorders that significantly impact patients' physical function and quality of life. Patients with spondyloarthritis experience a greater prevalence of cardiometabolic disorders, such as obesity, hypertension, dyslipidemia and diabetes mellitus, and these comorbidities are associated with increased spondyloarthritis disease activity and risk of cardiovascular events. This narrative review summarizes the evidence for a physiological link between inflammatory status and cardiometabolic comorbidities in spondyloarthritis, as well as the impact of interleukin (IL)-17 blockade versus other molecular mechanisms in patients with cardiometabolic conditions.
