D'Agostino, et al. aimed to evaluate whether treatment with secukinumab inhibits synovitis in patients with active PsA, as measured by PDUS. They found that secukinumab rapidly and significantly decreased synovitis, indicating a direct effect of IL-17 inhibition on the synovium in patients with PsA.

Thought to be the first study of its kind, Hamar, et al. have demonstrated the effect of one-year tofacitinib treatment on bone mineral density (BMD) in RA patients. While the association between RA and osteoporosis is well known, and evidence indicates that up to 70% of these patients have reduced BMD, little information is available on how the JAK inhibitor tofacitinib affects bone status, areal and volumetric BMD, and bone turnover markers. In this prospective study, 30 patients were assessed...

MRI studies have shown that BARI reduces joint inflammation and damage in patients with moderate-to-severe active RA. This review summarises the effects of BARI on structural joint damage progression and the mechanisms underlying these effects, using MRI data from across the clinical trial program. Early preclinical animal models showed a significant reduction in joint inflammation, ankle width, and bone resorption. Efficacy and safety of BARI have been confirmed in an extensive programme, inclu...

2020 unfolded apace, dominated by COVID-19 - we have all had to adapt in our practice and in our knowledge base. Amid this there have continued to be a constant flow of publications and science in cytokine signaling, and as in previous years as we come the end of 2020, I will highlight some of the notable papers of the year. You can find the most notable papers, as selected by CSF Steering Committee Chair Professor Iain McInnes, with links to their respective detailed summaries below:

Assessment of the association of baseline anti-CarbV and anti-MCV antibodies with response to treatment and radiographic progression in an RA population treated with either methotrexate or baricitinib: post-hoc analyses from RA-BEGIN

Autoantibodies associated with the onset of RA have gained attention in recent years as prognostic biomarkers. Though not used diagnostically, anti-CarbV (carbamylated vimentin) and anti-MCV (vimentin modified by citrullination) baseline titers are being investigated as predictors of treatment response. In this post-hoc analysis of data from the RA-BEGIN cohort of active RA patients, López-Romero and colleagues consider the potential predictive values of baseline anti-CarbV and anti-MCV titers r...

TOF demonstrated a dose-dependent promotion of human mesenchymal stromal cell (hMSC) recruitment under hypoxia, while inhibiting recruitment under normoxia. TOF also dose-dependently enhances osteogenic differentiation of hMSCs and reduces osteoclast differentiation and activity. As people age, they are more likely to suffer from fractures and delayed bone healing, as well as degenerative joint diseases or osteoporosis. Bone metabolism and fracture healing may be negatively affected by underlyin...

JAKi significantly increased osteoblast function but showed no direct effects on osteoclasts.JAK signalling has emerged as an important therapeutic target for inflammatory disease, and the immunomodulation of JAK inhibition is well defined. Less well understood is the influence of this new class of drugs on bone homeostasis. This is important, as cytokine dysregulation triggers bone loss, and periarticular erosions contribute to the pathogenesis of RA. This study investigated the effect of BARI ...

Data showing that TOF can inhibit unbalanced osteoclastogenesis in RA suggests that targeting the JAK-STAT pathway can halt bone erosion, as TOF has been shown to reduce articular bone erosion in RA and PsA.The authors in this review summarise current knowledge on the relationship between the immune system and the skeleton before examining the involvement of JAK-STAT signalling in bone homeostasis while discussing the evidence on the benefit of TOF on prevention of bone involvement in RA and PsA...

BTK is involved in both adaptive and innate immune responses and mediates signalling of several immune receptors of relevance to RA and SLE pathogenesis. Targeting BTK is a promising approach therefore for autoimmune disorders with aberrant B cell responses. Evobrutinib is a novel, highly specific, and irreversible BTK inhibitor. In vivo and animal models showed that evobrutinib modulated B cell and innate immune cell activation, was efficacious, and prevented joint damage. The potency of evobru...

Once daily baricitinib (BARI) inhibited radiographic progression of structural joint damage in patients with an inadequate response or intolerance to csDMARDs over 48 weeks.Current treatment goals aim to use DMARDs to inhibit structural joint damage and prevent long-term functional disability. In RA-BUILD¹, BARI was shown to significantly reduce radiographic joint damage progression in patients with active RA, with an intolerance or inadequate response to csDMARDs. Here, the authors report the l...
