Enhanced Association of Novel Cardiovascular Biomarkers Fetuin-A and Catestatin with Serological and Inflammatory Markers in Rheumatoid Arthritis Patients.

Rheumatoid arthritis (RA) is a chronic autoimmune disease associated with increased cardiovascular disease (CVD) risk and mortality. This work aimed to evaluate the serum levels of the novel CV biomarkers fetuin-A (fet-A), Dickkopf-1 (DKK-1), galectin-3 (Gal-3), interleukin-32 (IL-32), and catestatin (CST) in RA patients and their associations with RA parameters and CVD markers. A cohort of 199 RA patients was assessed for traditional CVD risk factors, RA disease activity, and biomarker levels. Carotid ultrasound was used to measure carotid intima-media thickness (cIMT) and carotid plaque presence (cPP). Multivariate analyses examined correlations between biomarkers and RA parameters, serological markers, and CVD markers. Adjusted models showed that elevated CST expression levels were associated with rheumatoid factor (RF) and anti-citrullinated protein antibody (ACPA) positivity (OR = 2.45, p = 0.0001 and OR = 1.48, p = 0.04, respectively) in the overall cohort and for RF in men and women, respectively. In addition, fet-A concentration was inversely associated with the erythrocyte sedimentation rate (ESR) in the overall cohort (ß = -0.15, p = 0.038) and in women (ß = -0.25, p = 0.004). Fet-A levels were also negatively correlated with disease activity (DAS28-ESR) scores (ß = -0.29, p = 0.01) and fibrinogen concentration (ß = -0.22, p = 0.01) in women. No adjusted associations were observed for Gal-3, DKK-1 or IL32 concentration. The study revealed no significant associations between the biomarkers and cIMT or cPP. The measurement of CST and fet-A levels could enhance RA patient management and prognosis. However, the utility of biomarkers for evaluating CV risk via traditional surrogate markers is limited, highlighting the need for continued investigations into their roles in RA.

Angiopoietin-2, vascular endothelial growth factor family, and heparin binding endothelial growth factor are associated with subclinical atherosclerosis in rheumatoid arthritis.

Introduction: Patients with RA are at a higher risk of developing CV diseases than the general population. The precise mechanisms are still unknown. We evaluated the associations between 8 plasma growth factors (GFs) (angiopoietin-2, EGF, HB-EGF, PLGF, TGF-α, VEGFa, VEGFc, and VEGFd) and subclinical arteriosclerosis in RA patients. Materials and methods: A total of 199 patients with RA treated at the Hospital Universitari Sant Joan de Reus (Spain) between 2011 and 2015 were included in this cross-sectional study. Carotid intima media thickness (cIMT), carotid plaque presence (cPP) and pulse wave velocity (PWV) were measured. GFs were measured with Bio-Plex Pro Human Cancer Biomarker Panel 2 (Bio-Rad). Multivariate models and partial least square discriminant analysis (PLS-DA) were used for analysis (RStudio, version 4.0.1). Results: Multivariate models showed that angiopoietin-2 was associated with cPP and PWV in the overall cohort (OR = 1.53 and ß = 0.20, respectively). VEGFc (ß = 0.29), VEGFa (ß = 0.26) and HB-EGF (ß = 0.22) were also associated with PWV. VEGFa (OR = 2.36), VEGFd (OR = 2.29), EGF (OR = 2.62), PLGF (OR = 2.54), and HB-EGF (OR = 2.24) were associated with cPP in men. According to PLS-DA, GFs were able to distinguish between patients with and without cPP in the overall cohort, male cohort, and female cohort. In women, angiopoietin-2 was associated with PWV (ß = 0.18). Conclusions: The selected GFs were closely related to atherosclerosis in patients with RA and are potential predictors of CV disease in patients with RA.

Association of bone edema with the progression of bone erosions quantified by hand magnetic resonance imaging in patients with rheumatoid arthritis in remission.

OBJECTIVE: To evaluate the association of synovitis, bone marrow edema (BME), and tenosynovitis in the progression of erosions quantified by hand magnetic resonance imaging (MRI) at 1 year in patients with early rheumatoid arthritis (RA) in remission. METHODS: A total of 56 of 196 patients with early RA in remission at 1 year and with available MRI data at baseline and at 12 months were included. MRI images were assessed according to the Rheumatoid Arthritis Magnetic Resonance Imaging Scoring (RAMRIS) system. Persistent remission was defined as 28-joint Disease Activity Score-erythrocyte sedimentation rate ≤ 2.6 and/or Simplified Disease Activity Index ≤ 3.3 and/or the new boolean American College of Rheumatology/European League Against Rheumatism remission criteria for a continuous period of at least 6 months. Progression of bone erosions was defined as an increase of 1 or more units in annual RAMRIS score for erosions compared to baseline. RESULTS: At 1 year, the majority of patients with RA in sustained remission showed some inflammatory activity on MRI (94.6% synovitis, 46.4% BME, and 58.9% tenosynovitis) and 19 of the 56 patients (33.9%) showed MRI progression of bone erosions. A significant difference was observed in MRI BME at 1 year, with higher mean score in patients with progression compared to nonprogression of erosions (4.8 ± 5.6 and 1.4 ± 2.6, p = 0.03). CONCLUSION: Subclinical inflammation was identified by MRI in 96.4% of patients with RA in sustained clinical remission. Significantly higher scores of BME after sustained remission were observed in patients with progression of erosions compared to patients with no progression. The persistence of higher scores of BME may explain the progression of bone erosions in patients with persistent clinical remission.
