Residual pain and fatigue are affected by disease perception in rheumatoid arthritis in sustained clinical and ultrasound remission.

Objective: Regardless of remission status, residual pain (RP) might persist in rheumatoid arthritis (RA). The aim of this study was to characterize RP, its perception, and patient-dependent features and to evaluate its possible association with residual synovitis in patients with RA in remission.

Methods: Ninety-seven patients with RA, including 68 in sustained clinical and ultrasound remission (Rem/RA) and 29 in high/moderate DAS28-CRP disease activity (H-Mo/RA) were enrolled in the study.

Modulation of IL-6 receptor/STAT3 downstream signaling in rheumatoid arthritis patients.

Interleukin-6 (IL-6) is a relevant cytokine in rheumatoid arthritis (RA) pathogenesis, potentially activating Janus kinases (JAK)-1, -2, and tyrosine kinase 2 (TYK2), and thus, three signal transducer and activator of transcription (STAT)-1, -3 or - 5 pathways. This pilot study aims to explore differences in phosphorylated (p)STAT3 levels among patients with RA, those not classified as RA (nRA), and healthy donors (HD), providing some clues on the relative contribution of each JAK protein to the downstream of the IL-6-induced STAT3 pathway. Clinical data and blood samples from 80 subjects (41 RA, 14 nRA, and 25 HD) were collected.

Target Therapy in Chronic Arthritis: The Unmet Needs, State-of-the-Art on Dual Biologic Treatments, and Future Perspectives.

Since the early 1990s, the introduction of biologic disease-modifying antirheumatic drugs (b-DMARDs) in managing rheumatological diseases has revolutionised the course of inflammatory chronic arthritis, improving the quality of life, slowing the radiographic progression, avoiding disability, preserving workability, and reducing mortality [...

Synovial tissue myeloid dendritic cell subsets exhibit distinct tissue-niche localization and function in health and rheumatoid arthritis.

Current rheumatoid arthritis (RA) treatments do not restore immune tolerance. Investigating dendritic cell (DC) populations in human synovial tissue (ST) may reveal pathways to reinstate tolerance in RA. Using single-cell and spatial transcriptomics of ST biopsies, as well as co-culture systems, we identified condition- and niche-specific DC clusters with distinct functions.

Methods: We retrospectively selected 81 seronegative and 404 seropositive RA patients receiving treatment with abatacept, anti-TNF alpha or tocilizumab. Effectiveness was evaluated by analysing drug survival using Kaplan-Meyer analysis over 10-year follow-up.

Serum Albumin Levels: A Biomarker to Be Repurposed in Different Disease Settings in Clinical Practice.

Serum albumin (ALB), one of the most important proteins in human physiology, has the main functions of maintaining plasma oncotic pressure and plasma volume, transporting hormones, vitamins, oligominerals and drugs, and exerting a powerful antioxidant-anti-inflammatory role. Its prognostic value in liver and malabsorption syndromes is well known. In this narrative review, an analysis of the most important studies evaluating the prognostic significance of low serum ALB levels in hospitalized patients was performed.

COVID-19 illness: Different comorbidities may require different immunological therapeutic targets.

Background: The SARS-CoV-2 pandemic has led to more than 6,870.000 deaths worldwide. Despite recent therapeutic advances, deaths in Intensive Care Units still range between 34 and 72%, comprising substantial unmet need as we move to an endemic phase.

Rheumatoid Arthritis from Easy to Complex Disease: From the "2022 GISEA International Symposium".

Rheumatoid Arthritis (RA) is a systemic disease with many different clinical phenotypes. RA could be classified according to disease duration, seropositivity for rheumatoid factor (RF) and/or anti-citrullinated protein antibodies (ACPA), joint subtype, clinical behaviourbehavior and many other subgroups. In this review, we summarize and discuss the multifaceted aspects of RA, focusing on the relationship between autoimmunity status and clinical outcome, achievement of remission and influence on treatment response, from the 2022 International GISEA/OEG Symposium.

The forgotten key players in rheumatoid arthritis: IL-8 and IL-17 - Unmet needs and therapeutic perspectives.

Despite the relevant advances in our understanding of the pathogenetic mechanisms regulating inflammation in rheumatoid arthritis (RA) and the development of effective therapeutics, to date, there is still a proportion of patients with RA who do not respond to treatment and end up progressing toward the development of joint damage, extra-articular complications, and disability. This is mainly due to the inter-individual heterogeneity of the molecular and cellular taxonomy of the synovial membrane, which represents the target tissue of RA inflammation. Tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) are crucial key players in RA pathogenesis fueling the inflammatory cascade, as supported by experimental evidence derived from animal models and the effectiveness of biologic-Disease Modifying Anti-Rheumatic Drugs (b-DMARDs) in patients with RA.

Immunogenicity of BNT162b2 mRNA SARS-CoV-2 vaccine in patients with psoriatic arthritis on TNF inhibitors.

Background: Scanty data on the immunogenicity of the BNT162b2 vaccine in patients with psoriatic arthritis (PsA) on Tumor Necrosis Factor inhibitors (TNFi) have been published.

Objective: To investigate the humoral response to BNT162b2 vaccination patients with PsA on TNFi, comparing immunogenicity with healthy controls.

Methods: Forty patients with classified PsA on TNFi undergoing vaccination with the BNT162b2 mRNA SARS-CoV-2 vaccine (BioNTech/Pfizer) were enrolled.

High CD14+ peripheral monocytes expression of ALX/FPR2 and BLT1 in low disease activity and remission status in rheumatoid arthritis: a piltot study.

Objectives: Specialised pro-resolving mediator (SPM) can dampen the acute inflammation through ERV1, ALX/FPR2 and BLT1 cell receptors and it is conceivable that their expression is dysregulated during chronic inflammation. The aim of this study was to evaluate the expression of ERV1, ALX/FPR2 and BLT1 on peripheral blood (PB) cells from rheumatoid arthritis (RA) patients.

Methods: At baseline, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), clinimetric indexes (28-joint disease activity score (DAS28) and clinical disease activity index (CDAI)), and PB samples were collected from 33 RA patients.

COVID-19 and RA share an SPP1 myeloid pathway that drives PD-L1+ neutrophils and CD14+ monocytes.

We explored the potential link between chronic inflammatory arthritis and COVID-19 pathogenic and resolving macrophage pathways and their role in COVID-19 pathogenesis. We found that bronchoalveolar lavage fluid (BALF) macrophage clusters FCN1+ and FCN1+SPP1+ predominant in severe COVID-19 were transcriptionally related to synovial tissue macrophage (STM) clusters CD48hiS100A12+ and CD48+SPP1+ that drive rheumatoid arthritis (RA) synovitis. BALF macrophage cluster FABP4+ predominant in healthy lung was transcriptionally related to STM cluster TREM2+ that governs resolution of synovitis in RA remission.

Inclusion of Synovial Tissue-Derived Characteristics in a Nomogram for the Prediction of Treatment Response in Treatment-Naive Rheumatoid Arthritis Patients.

Objective: This study applied a synovitis score obtained during routine care from ultrasound (US)-guided biopsies of synovial tissue (ST) in patients with rheumatoid arthritis (RA) and patients with other inflammatory and noninflammatory joint diseases to identify pretreatment synovial biomarkers associated with disease characteristics, and to integrate the findings into a multiparameter nomogram for use in baseline prediction of diagnosis and treatment response in treatment-naive rheumatoid arthritis (RA) patients.

Methods: The study enrolled a total of 1,015 patients with various autoimmune diseases (545 patients with RA, 167 patients with psoriatic arthritis [PsA], 199 patients with undifferentiated peripheral inflammatory arthritis [UPIA], 18 patients with crystal-induced arthritis, 26 patients with connective tissue diseases, and 60 patients with osteoarthritis [OA] [as part of the SYNGem cohort]). All patients underwent a US-guided ST biopsy at baseline, and patients were then stratified according to disease phase.

The Impact of Biologic Drugs on High-Density Lipoprotein Cholesterol Efflux Capacity in Rheumatoid Arthritis Patients.

Background: One of the most intriguing conundrums in patients with rheumatoid arthritis (RA) is the lack of correlation between cholesterol levels and cardiovascular (CV) events, diminishing the reliability of plasmatic lipid levels in estimating the CV risk. High-density lipoprotein cholesterol efflux capacity (HDLc-EC) directly indicates the functional ability of HDL to scavenge cholesterol from vascular wall and may provide better information on the atherogenic risk. The aim of this study was to examine the effects of different disease-modifying antirheumatic drugs on HDLc-EC in RA.

One year in review 2019: psoriatic arthritis.

Psoriatic arthritis (PsA) is an inflammatory arthritis belonging to spondyloarthritides (SpA), a group of rheumatologic diseases characterised bya wide spectrum of different clinical manifestations that tend to associate with various comorbidities and that may significantly compromise the quality of life of patients. Nowadays, it is well known how PsA may manifest in different clinical domains, in particular peripheral articular and periarticular involvement, axial involvement, skin and nail psoriasis. Moreover, the majority of patients with PsA develop comorbidities such as inflammatory bowel diseases, uveitis, but also cardiovascular diseases, psychiatric or pulmonary pathologies.
