The etiology of psoriatic arthritis (PsA) is poorly understood but current evidence supports an interaction between genetic and environmental factors that coalesce to promote local tissue inflammation.1-3 The pivotal cytokines that underlie the local inflammatory response in a wide range of tissues are interleukin (IL) 23, IL-17 and tumor necrosis factor (TNF).4 The central contribution…

Background & objectives: Patients with rheumatic and musculoskeletal diseases (RMDs) may be at an increased risk of SARS-CO-V2 infection as a result of underlying disease, associated comorbidities and use of potentially immunosuppressive treatments. Further, concern exists regarding whether individuals with rheumatic diseases potentially experience more severe COVID-19 and poorer outcomes. This study was undertaken to…
A study found DNA methylation profiling may predict if a patient will progress from a diagnosis of undifferentiated arthritis to that of rheumatoid arthritis (RA). The findings also suggest a pre-established epigenetic signature exists in patients diagnosed with undifferentiated arthritis that evolves into RA.
Secher et al. evaluated the risk of pre-eclampsia in pregnant patients with RA, axSpA or PsA, assessing the effect of disease activity and disease-modifying anti-rheumatic drugs on this risk.
COVID-19 vaccinations are safe for patients with systemic lupus erythematosus (SLE), with manageable side effects and a low incidence of flare, according to a recently published study in The Lancet.1 The use of mRNA vaccines, such as those from Pfizer-BioNTech and Moderna, which have been viewed as riskier than traditional vaccines because of a concern…
Sarcoidosis is a multisystem disease characterized by noncaseating granulomas in affected tissues, mostly involving the lungs and lymph nodes.1,2 The etiology of sarcoidosis remains unknown but is thought to be due to an inflammatory response to an antigen exposure in genetically predisposed individuals.1 Tumor necrosis factor-α (TNF‑α), a pro-inflammatory cytokine, plays an essential role in…
A 26-year-old woman presented to our emergency department (ED) with intermittent fevers, nausea and vomiting. She had a past medical history of well-controlled, anti-nuclear antibody positive and rheumatoid factor negative polyarticular juvenile idiopathic arthritis (pJIA) and Crohn’s disease. Her maintenance treatment consisted of monthly intravenous infliximab, 10 mg of oral methotrexate weekly and 20 mg…
A 44-year-old woman presented to the emergency department with bifrontal headaches that had started approximately one month earlier. She was diagnosed with migraines and discharged home. Three days later, the patient returned to the emergency department upon recurrence of her headaches, and this time she also reported abnormal leg movements. A computerized tomography (CT) scan…
A 17-year-old woman presents with chronic finger pain experienced over six months that is worse in the mornings. On physical exam, the patient has no joint swelling, pain on range of motion or limitation of range of motion in any of her finger joints. She has a tender, subcutaneous, firm, flesh-colored nodule on the lateral…
