An inverse association between alcohol consumption and disease activity and functional impairment has been observed in patients with spondyloarthritis (SpA). However, neither this association nor the ...influence of smoking has been investigated in peripheral manifestations of SpA.
The objective of this study was to analyze the association between smoking and alcohol consumption and the presence of peripheral musculoskeletal manifestations (arthritis, enthesitis or dactylitis) and to determine the specific location of these manifestations.
Patients from the worldwide cross-sectional ASAS-PerSpA study with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or psoriatic arthritis (PsA) according to their rheumatologist were included. Generalised linear mixed models used peripheral manifestation (or location) as a dependent variable, smoking status and alcohol consumption as fixed effects and country as a random effect. The interaction between smoking and alcohol was tested. Analyses were performed for each diagnosis (axSpA, pSpA and PsA).
A total of 4181 patients were included. In axSpA patients, smoking was associated with a lower prevalence of any peripheral manifestation, and current alcohol consumption was associated with a lower prevalence of both current arthritis and current enthesitis. In pSpA patients, current alcohol consumption was associated with a lower prevalence of current arthritis or enthesitis. In PsA patients, a significant association was found for arthritis with smoking and for enthesitis with alcohol consumption, and current alcohol consumption was associated with a lower prevalence of current arthritis or enthesitis.
Taking into account the country, smoking and alcohol are associated with a lower prevalence of peripheral manifestations.

Objectives
(1) To evaluate clinical and molecular cardiovascular disease (CVD) signs and their relationship with psoriatic arthritis (PsA) features and (2) to identify a clinical patient profile ...susceptible to benefit from methotrexate (MTX) and/or apremilast regarding CVD risk.
Methods
This cross‐sectional study included 100 patients with PsA and 100 age‐matched healthy donors. In addition, an exploratory cohort of 45 biologically naïve patients treated for 6 months with apremilast, MTX or combined therapy according to routine clinical practice was recruited. Extensive clinical and metabolic profiles were obtained. Ninety‐nine surrogate CVD‐related molecules were analysed in plasma and peripheral blood mononuclear cells (PBMCs). Hard cluster analysis was performed to identify the clinical and molecular phenotypes. Mechanistic studies were performed on adipocytes.
Results
Cardiometabolic comorbidities were associated with disease activity and long‐term inflammatory status. Thirty‐five CVD‐related proteins were altered in the plasma and PBMCs of PsA patients and were associated with the key clinical features of the disease. Plasma levels of some of the CVD‐related molecules might distinguish insulin‐resistant patients (MMP‐3, CD163, FABP‐4), high disease activity (GAL‐3 and FABP‐4) and poor therapy outcomes (CD‐163, LTBR and CNTN‐1). Hard cluster analysis identified two phenotypes of patients according to the rates of cardiometabolic comorbidities with distinctive clinical and molecular responses to each treatment.
Conclusions
(1) Novel CVD‐related proteins associated with clinical features could be emerging therapeutic targets in the context of PsA and (2) the pleiotropic action of apremilast could make it an excellent choice for the management of PsA patients with high CVD risk, targeting metabolic alterations and CVD‐related molecules.
•The prevalence of acute anterior uveitis in the REGISPONSER population was 16.2%.•Patients with acute anterior uveitis as first symptom showed a better function and less structural damage than ...patients with uveitis after the rheumatic symptoms onset.•The moment of appearance of acute anterior uveitis had no impact on the treatment received.
To describe the time of onset of acute anterior uveitis (AAU) relative to the appearance of rheumatic symptoms and to determine its association with the evolution of the spondyloarthritis (SpA) in terms of activity, structural damage, functional ability and treatment.
This was a cross-sectional study with data extracted from the REGISPONSER (SpA Registry of the Spanish Rheumatology Society). Thirty-one centres participated, and patients with SpA according to the ESSG criteria were included from 2004 to 2007. Patients were classified according to the time of uveitis appearance with regard to rheumatic symptom onset (before, concomitant with, or after rheumatic symptom onset). We compared the clinical characteristics, disease activity, radiographic damage and functional ability between “AAU before or concomitant with rheumatic symptoms” and “AAU after rheumatic symptoms onset”. Finally, we compared whether the time of appearance of AAU had an impact on the use of conventional and biological disease-modifying antirheumatic drugs (csDMARDs and bDMARDs, respectively).
A total of 2367 patients were included in REGISPONSER, with an AAU prevalence of 16.2% (379 patients). Patients with AAU before/concomitant with rheumatic symptom onset (n=59) exhibited better functional ability (BASFI, OR 0.85 0.73-0.99) and less structural damage (spinal BASRI, OR 0.88 0.79-0.99). Additionally, this group of patients was older at SpA symptom onset (OR 1.05 1.02-1.09) and had a shorter diagnosis delay (OR 0.90 0.84-0.96) compared patients with AAU after rheumatic symptom onset (n=229). No statistically significant differences in the use of DMARDs were noted (27.9% vs 23.2% for csDMARD use and 15.3% vs 20.3% for bDMARD use in patients with AAU before or concomitant with rheumatic symptom onset vs after rheumatic symptom onset, respectively).
Patients presenting with a first episode of AAU before/concomitant with the onset of rheumatic symptoms had less severe disease (better functional ability and less structural damage) and a shorter diagnosis delay; however, the time of AAU onset did not impact the treatments received.
To determine the potential impact of sex-specific disease-related characteristics on cardiovascular (CV) disease in axial spondyloarthritis (axSpA).
Cross-sectional study of the Spanish AtheSpAin ...cohort to study CV disease in axSpA. Data on carotid ultrasound and CV disease and disease-related features were collected.
611 men and 301 women were recruited. Classic CV risk factors were significantly less prevalent in women, who also showed a lower frequency of carotid plaques (p = 0.001), lower carotid intima-media thickness (IMT) values (p<0.001) and CV events (p = 0.008). However, after adjustment for classic CV risk factors, only the differences with respect to carotid IMT remained statistically significant. Women showed higher ESR at diagnosis (p = 0.038), and more active disease (ASDAS, p = 0.012, and BASDAI, p<0.001). They had shorter disease duration (p<0.001), lower prevalence of psoriasis (p = 0.008), less structural damage (mSASSS, p<0.001), and less mobility limitation (BASMI, p = 0.033). To establish whether these findings could lead to sex differences in CV disease burden, we compared the prevalence of carotid plaques in men and women with the same level of CV risk stratified according to the Systematic Coronary Risk Evaluation (SCORE). Men included in the low-moderate CV risk SCORE category had more carotid plaques (p = 0.050), along with longer disease duration (p = 0.004), higher mSASSS (p = 0.001) and psoriasis (p = 0.023). In contrast, in the high-very high-risk SCORE category, carotid plaques were observed more frequently in women (p = 0.028), who were characterized as having worse BASFI (p = 0.011), BASDAI (p<0.001) and ASDAS (p = 0.027).
Disease-related features may influence the expression of atherosclerosis in patients with axSpA. This may be especially applicable to women at high CV risk, characterized by greater disease severity and more severe subclinical atherosclerosis than men, suggesting a stronger interaction between disease activity and atherosclerosis in women with axSpA.
1) To characterize the inflammatory proteome of synovial fluid (SF) from patients with Psoriatic Arthritis (PsA) using a high-quality throughput proteomic platform, and 2) to evaluate its potential ...to stratify patients according to clinical features.
Inflammatory proteome profile of SF from thirteen PsA patients with active knee arthritis were analyzed using proximity extension assay (PEA) technology (Olink Target 96 Inflammation panel). Four patients with OA were included as control group.
Seventy-nine inflammation-related proteins were detected in SF from PsA patients (SF-PsA). Unsupervised analyzes of the molecular proteome profile in SF-PsA identified two specific phenotypes characterized by higher or lower levels of inflammation-related proteins. Clinically, SF-PsA with higher levels of inflammatory proteins also showed increased systemic inflammation and altered glucose and lipid metabolisms. Besides, SF from PsA patients showed 39 out of 79 proteins significantly altered compared to SF-OA specifically related to cell migration and inflammatory response. Among these, molecules such as TNFα, IL-17A, IL-6, IL-10, IL-8, ENRAGE, CCL20, TNFSF-14, OSM, IFNγ, MCP-3, CXCL-11, MCP4, CASP-8, CXCL-6, CD-6, ADA, CXCL-10, TNFβ and IL-7 showed the most significantly change.
This is the first study that characterizes the inflammatory landscape of synovial fluid of PsA patients by analyzing a panel of 92 inflammatory proteins using PEA technology. Novel SF proteins have been described as potential pathogenic molecules involved in the pathogenesis of PsA. Despite the flare, inflammatory proteome could distinguish two different phenotypes related to systemic inflammation and lipid and glucose alterations.
To compare the effect of inflammation on subclinical atherosclerosis using carotid ultrasound in patients with rheumatoid arthritis (RA) and spondyloarthritis (SpA).
Cross-sectional study including ...347 participants (148 RA, 159 SpA, and 40 controls). We measured the carotid intima media thickness (cIMT) and detection of atheromatous plaques using carotid ultrasound. We recorded disease activity (DAS28-CRP/ASDAS-CRP) and traditional cardiovascular risk factors. We performed descriptive, bivariate, and linear multivariate analyses (dependent variable: cIMT) to evaluate the influence of diagnosis on cIMT in all patients. Two additional multivariate analyses were performed by stratifying patients according to their inflammatory activity.
cIMT correlated with the mean CRP during the previous 5 years in RA, but not with CRP at the cut-off date. We did not find such differences in patients with SpA. The first multivariate model revealed that increased cIMT was more common in patients with RA than in those with SpA (β coefficient, 0.045; 95% confidence interval (95% CI), 0.0002-0.09;
= 0.048) after adjusting for age, sex, disease course, and differential cardiovascular risk factors (arterial hypertension, smoking, statins, and corticosteroids). The second model revealed no differences in cIMT between the 2 groups of patients classified as remission-low activity (β coefficient, 0.020; 95% CI, -0.03 to 0.080;
= 0.500). However, when only patients with moderate-high disease activity were analysed, the cIMT was 0.112 mm greater in those with RA (95% CI, 0.013-0.212;
= 0.026) than in those with SpA after adjusting for the same variables.
Subclinical atherosclerosis measured by carotid ultrasound in patients with RA and SpA is comparable when the disease is well controlled. However, when patients have moderate-high disease activity, cIMT is greater in patients with RA than in those with SpA after adjusting for age, sex, disease course, and cardiovascular risk factors. Our results point to greater involvement of disease activity in subclinical atherosclerosis in patients with RA than in those with SpA.
Radiographic axial spondyloarthritis (r-axSpA) is a chronic inflammatory form of arthritis in which tumor necrosis factor (TNF)-α, a potent inducer of inflammatory response and a key regulator of ...innate immunity and of Th1 immune responses, plays a central role. NETosis is a mechanism of innate immune defense that is involved in diverse rheumatology diseases. Nevertheless, spontaneous NETosis generation in r-axSpA, its association to disease pathogenesis, and the NETosis involvement on anti-TNF-α therapy's effects has never been explored.
Thirty r-axSpA patients and 32 healthy donors (HDs) were evaluated. Neutrophil extracellular trap (NET) formation, mediators of signal-transduction cascade required for NETosis induction and cell-free NETosis-derived products were quantified. An additional cohort of 15 r-axSpA patients treated with infliximab (IFX) for six months were further analyzed. In vitro studies were designed to assess the effects of IFX in NETosis generation and the inflammatory profile triggered.
Compared to HDs, neutrophils from r-axSpA patients displayed augmented spontaneous NET formation, elevated expression of NET-associated signaling components, nuclear peptidylarginine deiminase 4 translocation and increased citrullinated histone H3. Furthermore, patients exhibited altered circulating levels of cell-free NETosis-derived products (DNA, nucleosomes and elastase). Additional studies revealed that cell-free NETosis-derived products could be suitable biomarkers for distinguish r-axSpA patients from HDs. Correlation studies showed association between cell-free NETosis-derived products and clinical inflammatory parameters. Besides, nucleosomes displayed potential as a biomarker for discriminate patients according to disease activity. IFX therapy promoted a reduction in both NETosis generation and disease activity in r-axSpA patients. Mechanistic in vitro studies further unveiled the relevance of IFX in reducing NET release and normalizing the augmented inflammatory activities promoted by NETs in mononuclear cells.
This study reveals that NETosis is enhanced in r-axSpA patients and identifies the NETosis-derived products as potential disease activity biomarkers. In addition, the data suggests the potential role of NET generation analysis for assessment of therapeutic effectiveness in r-axSpA.
Background:
Axial spondyloarthritis (axSpA) patients are known to have a higher prevalence of several comorbidities, including, among others, an increased risk of atherosclerosis, hypertension, ...dyslipidemia, and diabetes. The purpose of the present study was to determine whether the sum of traditional cardiovascular (CV) risk factors is related to disease characteristics, such as disease activity, in patients with axSpA.
Methods:
A cross-sectional study that encompassed 804 patients with axSpA was conducted. Patients were assessed for the presence of five traditional CV risk factors (diabetes mellitus, dyslipidemia, hypertension, obesity, and smoking status), and disease activity measurements. A multivariable regression analysis was performed to evaluate whether the number of classic CV risk factors was independently associated with specific features of the disease, to include disease activity.
Results:
A multivariable analysis showed that Ankylosing Spondylitis Disease Activity Score–C reactive protein (ASDAS-CRP) activity score was significantly higher in patients with 1 beta coefficient 0.3 (95% confidence interval (CI) 0.1–0.5), p = 0.001 and ⩾2 beta coefficient 0.5 (95% CI 0.3–0.7), p = 0.000 CV risk factors compared with those without CV risk factors. Similarly, patients with 1 OR 2.00 (95%CI 0.99–4.02), p = 0.053 and ⩾2 OR 3.39 (95%CI 1.82–6.31), p = 0.000 CV risk factors had a higher odds ratio for the presence of high disease activity compared with the zero CV category. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) activity score was significantly associated with the number of CV risk factors, being higher in patients with more CV risk factors. These relationships showed a CV risk factor-dependent effect being beta coefficients and ORs higher for the effect of ⩾2 over 1 CV risk factor.
Conclusion:
Among patients with axSpA, as the number of traditional CV risk factors increased, disease activity similarly increases in an independent manner.
Aims:
To evaluate the association of estimated cardiovascular (CV) risk and subclinical atherosclerosis with radiographic structural damage in patients with axial spondyloarthritis (axSpA).
Methods:
...Cross-sectional study including 114 patients axSpA from the SpA registry of Córdoba (CASTRO) and 132 age- and sex-matched healthy controls (HCs). Disease activity and the presence of traditional CV risk factors were recorded. The presence of atherosclerotic plaques and carotid intima media thickness (cIMT) were evaluated through carotid ultrasound and the SCORE index was calculated. Radiographic damage was measured though modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS). The association between mSASSS and SCORE was tested using generalized linear models (GLM), and an age-adjusted cluster analysis was performed to identify different phenotypes dependent on the subclinical CV risk.
Results:
Increased traditional CV risk factors, SCORE, and the presence of carotid plaques were found in axSpA patients compared with HCs. The presence of atherosclerotic plaques and SCORE were associated with radiographic structural damage. The GLM showed that the total mSASSS was associated independently with the SCORE β coefficient 0.24; 95% confidence interval (CI) 0.10–0.38 adjusted for disease duration, age, tobacco, C-reactive protein, and non-steroidal anti-inflammatory drugs (NSAID) intake. Hard cluster analysis identified two phenotypes of patients. Patients from cluster 1, characterized by the presence of plaques and increased cIMT, had a higher prevalence of CV risk factors and SCORE, and more structural damage than cluster two patients.
Conclusion:
Radiographic structural damage is associated closely with increased estimated CV risk: higher SCORE levels in axSpA patients were found to be associated independently with mSASSS after adjusting for age, disease duration, CRP, tobacco and NSAID intake.
To determine the potential impact of extra-articular manifestations (EAMs) on disease characteristics and cardiovascular (CV) risk in patients with axial spondylarthritis (axSpA).
This is a ...cross-sectional study from the AtheSpAin cohort, a Spanish multicenter cohort to study atherosclerosis in axSpA. Data on the history of CV events, subclinical carotid atherosclerosis, and disease-related features, including EAMs, were collected.
888 axSpA patients were recruited. Concomitant acute anterior uveitis (AAU), psoriasis (PSO), and inflammatory bowel disease (IBD) were present in 177 (19.9%), 96 (10.8%), and 57 (6.4%) patients, respectively. When compared with axSpA patients without EAMs, a significant increase in past CV events was observed in patients with PSO (9% versus 4%, p = 0.048) and in those with at least one EAM (7% versus 4%, p = 0.032) or with more than one EAM (11% versus 4%, p = 0.022). The frequency of carotid plaques and the values of cIMT were higher in patients with EAMs than in those without EAMs, although only the univariable analysis for carotid plaques in patients with PSO (39% versus 30%, p = 0.038) and for cIMT in patients with AAU (665 ± 156 µm versus 637 ± 139 µm, p = 0.042) and those with at least one EAM (661 ± 155 µm versus 637 ± 139 µm, p = 0.024) showed significant results. In addition, patients with PSO or IBD were found to have specific disease-related features, such as higher ESR at diagnosis, and more frequent use of glucocorticoids and TNF inhibitors than those without EAMs. Also, PSO patients had more commonly peripheral involvement and those with AAU more severe radiographic damage than those without EAMs. The frequency of HLA B27 was higher in patients with AAU and lower in those with PSO or IBD compared to those without EAMs.
Patients with axSpA and EAMs, in addition to displaying their own disease-related features, are likely to have an increased CV risk that appears proportional to the number of EAMs and could be related to proatherogenic factors other than traditional CV risk factors, such as the inflammatory load and the use of glucocorticoids.
