ITGA5+ synovial fibroblasts orchestrate proinflammatory niche formation by remodelling the local immune microenvironment in rheumatoid arthritis

  • Annals of the Rheumatic Diseases
  • February 2025
  • The aim of this study is to explore the phenotypic diversity of tissue-resident synovial fibroblasts and their involvement in the inflammatory response in rheumatoid arthritis (RA). The researchers found that ITGA5+ synovial fibroblasts may influence RA progression by promoting the differentiation of CXCL13hiPD–1hi TPHs and altering the proinflammatory microenvironments. Targeting this specific fibroblast subpopulation could, therefore, serve as a promising therapeutic approach for RA.

Delineating inflammatory from non-inflammatory mechanisms for therapy optimization in psoriatic arthritis

  • Nature Reviews. Rheumatology
  • March 2025
  • Psoriatic arthritis (PsA) is more anatomically diverse than rheumatoid arthritis, involving not only synovitis but also enthesitis, peritendinitis, tenosynovitis, osteitis, and periostitis. This complexity makes it difficult to define the resolution of inflammation post-treatment, especially in cases of enthesitis. Drawing from rheumatoid arthritis research, we categorize PsA patients with inadequate treatment response into two subgroups: persistent inflammatory PsA (PIPsA) and non-inflammatory PsA (NIPsA). NIPsA is characterized by the absence of joint inflammation, confirmed by clinical assessment and imaging, with normalized inflammatory markers. NIPsA may be linked to obesity, biomechanical pain, osteoarthritis, fibromyalgia, post-inflammatory damage, and central pain mechanisms. This article discusses how PsA composite outcome measures relate to these phenotypes and suggests that this framework could reduce unnecessary therapy cycles and guide future trial designs.

Nutritional guidance in spondyloarthritis: confronting the evidence gap

  • Current Opinion in Rheumatology
  • March 2025
  • The goal of this review is to synthesize the current evidence on the role of particular dietary patterns in managing spondyloarthritis (SpA). Most patients recognize the significance of a healthy diet and its potential advantages in controlling symptoms. Furthermore, there is growing patient demand for nutritional guidance, which should be incorporated into standard SpA treatment to improve patient outcomes.

The role of the immune system in osteoarthritis: mechanisms, challenges and future directions

  • Nature Reviews. Rheumatology
  • March 2025
  • Osteoarthritis (OA) was traditionally seen as a wear-and-tear condition, but recent research has highlighted its inflammatory aspects, such as low-grade peripheral inflammation and synovitis, which play a significant role in disease progression. Advances in technology have revealed a diverse array of immune cells in the joints, particularly in the synovium and infrapatellar fat pad. Notably, synovial lymphoid structures, circulating autoantibodies, and changes in memory T and B cell populations have been observed in OA, suggesting a potential autoimmune component. These immune changes vary across disease phenotypes, and better understanding their molecular endotypes is essential for patient stratification, novel therapies, and improved treatment strategies. Additionally, exploring systemic changes, including the gut-joint axis and microbial dysbiosis, could offer new management options for OA.

CD19-targeting CAR T-cell therapy in patients with diffuse systemic sclerosis: a case series

  • The Lancet Rheumatology
  • February 2025
  • CD19-targeting chimeric antigen receptor (CAR) T-cell therapy has shown significant success in treating patients with systemic lupus erythematosus. However, its effects on organ manifestations in systemic sclerosis remain unclear. Given that B cells play a key role in the pathogenesis of systemic sclerosis, this study offers an in-depth analysis of the impact of CD19-targeting CAR T-cell therapy in these patients. The findings provide the first evidence suggesting that this therapy may help slow the progression of fibrotic organ manifestations in systemic sclerosis.

Genome-Wide Aggregated Trans Effects Analysis Identifies Genes Encoding Immune Checkpoints as Core Genes for Rheumatoid Arthritis

  • Arthritis & Rheumatology
  • February 2025
  • The sparse effector "omnigenic" hypothesis suggests that the polygenic influence of common single nucleotide polymorphisms (SNPs) on complex traits is mediated by trans effects that converge on a small set of core genes. This study aimed to identify core genes involved in rheumatoid arthritis by examining the association between the disease and genome-wide aggregated trans effects (GATE) scores for gene expression, both as transcripts in whole blood and as circulating protein levels. The findings emphasize the importance of immune checkpoints in rheumatoid arthritis and point to potential therapeutic targets.

A Multicenter Study of Associations between Area-Level Child Opportunity, Initial Disease Severity and Outcomes among Children with Lupus

  • Arthritis Care & Research
  • March 2025
  • Child opportunity refers to the neighborhood resources and conditions that impact healthy childhood development. This study explored whether area-level opportunities are linked to disease severity or control in a diverse, multi-center cohort of patients with childhood-onset systemic lupus erythematosus (cSLE). Structural inequities in child opportunity at the community level may contribute to disparities in cSLE severity and management. Targeting interventions in communities with limited child opportunities could enhance access to pediatric subspecialty care and improve cSLE outcomes.

Non-Pharmacological Pain Management of Rheumatoid Arthritis

  • Current Rheumatology Reports
  • March 2025
  • Many people with rheumatoid arthritis (RA) continue to experience pain despite using disease-modifying antirheumatic drugs. This review aims to summarize the current evidence on non-pharmacological strategies for managing pain in RA. The researchers suggest using non-pharmacologic approaches primarily to improve pain-related outcomes, such as physical function and overall health, rather than directly targeting pain itself. However, the evidence supporting non-pharmacological interventions for pain is limited, highlighting the urgent need for large-scale randomized controlled trials focused specifically on pain management.
