Background: Though biologic agents have significantly improved the treatment of inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, and axial spondyloarthritis), high costs, stringent regulations, strict reimbursement criteria, and existing patents have limited patient access to treatments. While being highly similar in quality, safety, and efficacy to biologic reference products, biosimilars can reduce the financial burden and prevent underutilization of medication.

Objective: The objective of this initiative was to develop an evidence-based consensus of overarching principles and recommendations aimed at standardizing the use of biosimilars in treating inflammatory arthritis in the Gulf region.

Background: Autoimmune rheumatic diseases (ARDs) are characterized by immune dysfunction and associated with an increased risk of infections, which were of significant concern during the coronavirus disease 2019 (COVID-19) pandemic. Variable rates of COVID-19 incidence have been reported in patients with ARDs; however, the true effect of this infection on this patient population is still unclear. We, therefore, aimed to evaluate the COVID-19 prevalence among a multiethnic cohort of patients with ARDs in Qatar.

Background: Severe COVID-19 is thought to be caused by immune overdrive and cytokine storm. One of the cytokine storm syndromes frequently induced by infections is secondary hemophagocytic lymphohistiocytosis (HLH) which can be assessed using H-score. In this study, we aimed to evaluate the rate of patients with COVID-19 who meet HLH criteria based on H-score and the association of H-score with poor outcomes.

Article Synopsis
  • Anti-TNF agents, commonly used to treat autoimmune and inflammatory bowel diseases, have been associated with neurological adverse events, including demyelination.
  • Three case studies documented patients who developed neurological symptoms, such as dizziness and numbness, after using adalimumab or infliximab, with MRI scans suggesting multiple sclerosis.
  • Discontinuing anti-TNF treatment led to symptom resolution in one case, but relapses occurred in others, indicating a potential causal link between these medications and demyelination that needs further investigation.
