Tailoring Optic Neuritis Evaluation Using Risk Profiles - NMOSD: Current Perspectives

A new report calls for high clinical suspicion of optic neuritis in patients with neuromyelitis optica spectrum disorder (NMOSD) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD).

The significant relative risk of optic neuritis seen in these—and other inflammatory conditions— should escalate suspicion and guide evaluation for appropriate treatment when patients with these diagnoses present with new visual symptoms, according to James B. Davis, MBA, a research fellow at

Psoriasis is Frequently Underdiagnosed in Patients with Axial Spondyloarthritis - Spondyloarthritis Peer-to-Peer

Results from a cross-sectional survey of a Dutch axial spondyloarthritis (axSpA) cohort, recently published in Arthritis Research & Therapy by Rondags and colleagues, suggest that psoriasis is likely underdiagnosed, especially milder cases, when relying solely on previous doctor-made diagnoses.1

Using a self-reported screening tool with photos of psoriasis lesions, 13% of axSpA patients indicated having psoriasis symptoms currently or in the past. However, only about half of those patients had

Respiratory Syncytial Virus: Are Platelets Partly to Blame? - RSV in Adults

Platelets did not undergo activation or degranulation upon respiratory syncytial virus (RSV) exposure in vitro, suggesting they may not directly participate in the immune pathology underlying severe RSV infections, according to the results of a study recently published in the open-access journal Access Microbiology.1

RSV is a major cause of lower respiratory tract infections. A subset of patients develop severe lower respiratory tract infections requiring hospitalization and supplemental oxygen

Early Onset of Spondyloarthritis Symptoms Challenges Diagnostic Delay - Spondyloarthritis Peer-to-Peer

A recent cross-sectional study of over 4000 patients with spondyloarthritis (SpA) reveals that those with early onset of extra-musculoskeletal manifestations (EMMs), such as psoriasis, face shorter diagnostic delays compared to onset with common musculoskeletal symptoms (MMs) such as back pain.1

These findings, which were published in August 2023 in the journal RMD Open by Puche-Larrubia and colleagues, challenge the perception that most SpA begins with musculoskeletal manifestations and sugges
