Do the Activity Indices Used in Axial Spondyloarthritis Capture the Relationships Between Obesity, Smoking and Disease Activity in the Same Way?

Obesity and smoking have been related to increased disease activity in axial spondyloarthritis (axSpA), but these associations might vary depending on the composite index chosen to assess disease activity. We aimed to check this possibility. Three hundred and thirty consecutive patients were recruited from the monographic axSpA unit of a university center.

F-FDG positron emission tomography as a marker of disease activity and treatment response in ankylosing spondylitis and psoriatic arthritis.

The ability of F-FDG positron emission tomography (PET) to track disease activity and treatment response in patients with Ankylosing Spondylitis (AS) or Psoriatic Arthritis (PsA) remains unclear. Here, we assessed whether F-FDG uptake is a marker of disease activity and treatment response in AS or PsA, and explored the ability of F-FDG to predict treatment response. Patients with AS (n = 16) or PsA (n = 8) who were scheduled to initiate treatment with biologics were recruited.

Acroosteolysis and facial dysmorphia: a new case of Hajdu-Cheney syndrome.

Hajdu-Cheney syndrome or acro-dento-osteo-dysplasia syndrome is a rare disease characterized by band osteolysis of distal phalanges and facial dysmorphia, among other manifestations. We present the case of a 45-year-old male who consulted for mechanical joint pain of both hands, facial dysmorphism, cranio-facial alterations, and digital telescoping with acroosteolysis.

Interleukin-17-targeted treatment in patients with spondyloarthritis and associated cardiometabolic risk profile.

Spondyloarthritis is a group of immune-mediated rheumatic disorders that significantly impact patients' physical function and quality of life. Patients with spondyloarthritis experience a greater prevalence of cardiometabolic disorders, such as obesity, hypertension, dyslipidemia and diabetes mellitus, and these comorbidities are associated with increased spondyloarthritis disease activity and risk of cardiovascular events. This narrative review summarizes the evidence for a physiological link between inflammatory status and cardiometabolic comorbidities in spondyloarthritis, as well as the impact of interleukin (IL)-17 blockade versus other molecular mechanisms in patients with cardiometabolic conditions.

Differentiated Effect of Smoking on Disease Activity and Quality of Life among Different Spondyloarthritis Phenotypes.

Background And Aims: The effect of smoking on disease activity and quality of life (QoL) in spondyloarthritis (SpA) is far from clear. We aimed to evaluate the relationship between smoking and these outcomes in patients with axial SpA (axSpA) and psoriatic arthritis (PsA).

Patients And Methods: This cross-sectional observational multicenter study included 242 patients with axSpA and 90 with PsA.

Humoral responses against HDL are linked to lipoprotein traits, atherosclerosis, inflammation and pathogenic pathways during early arthritis stages.

Objective: Chronic inflammation and immune dysregulation are crucial mechanisms for atherosclerosis in RA. Recent evidence suggests a link via humoral responses against high-density lipoproteins (HDL). This study aimed to characterize the specificity, clinical relevance and emergence of humoral responses against HDL along disease course, especially during the earliest phases of arthritis.

Do NSAIDs Take Us Away From Treatment Goals in Axial Spondyloarthritis: A Story About Dysbiosis or Just a Matter of Bias?

Non-steroidal anti-inflammatory drugs (NSAIDs) remain the mainstay of treatment for spondyloarthritides (SpA), a group of entities with common clinical and pathophysiological aspects, but also with differential features. Although NSAIDs provide significant symptomatic relief, especially for joint pain and morning stiffness, their role in achieving and maintaining the treatment goals advocated by the treat to target strategy in SpA is not entirely clear. These agents can induce changes in the composition of the intestinal microbiota, also favoring an alteration of the barrier function in the gut epithelium.

Performance of the ASAS Health Index for the Evaluation of Spondyloarthritis in Daily Practice.

Objective: The Assessment of SpondyloArthritis international Society Health Index (ASAS HI) is a tool designed to assess disease impact in spondyloarthritis (SpA), but its clinical performance is barely known. We aimed to test the clinimetric properties of ASAS HI in a real clinical setting.

Methods: This cross-sectional study included 111 consecutive patients with SpA.

Biological Dose Tapering in Daily Clinical Practice: A 10 Year Follow-up Study.

Objective: To describe practice patterns, long-term outcome, and related factors, in relation to biological therapies tapering in rheumatoid arthritis (RA) patients in a well-controlled real-world setting.

Methods: An observational longitudinal retrospective 10-year study was conducted in all RA patients receiving biological agents in an RA clinic from May 2003 to October 2013. Biological treatment of patients with sustained DAS28<3.

High triglycerides and low high-density lipoprotein cholesterol lipid profile in rheumatoid arthritis: A potential link among inflammation, oxidative status, and dysfunctional high-density lipoprotein.

Background: The interactions between inflammation and lipid profile in rheumatoid arthritis (RA) are poorly understood. The lipid profile study in RA has been biased toward lipoprotein levels, whereas those of triglycerides (TGs) and lipoprotein functionality have been underestimated.

Objectives: Since recent findings suggest a role for TG and TG-rich lipoproteins (TRL) on inflammation, we aimed to evaluate a combined lipid profile characterized by high TG and low high-density lipoprotein cholesterol levels (TGHDL) in RA.

Red cell distribution width is associated with endothelial progenitor cell depletion and vascular-related mediators in rheumatoid arthritis.

Objectives: The role of Red Cell Distribution Width (RDW) as a predictor of cardiovascular (CV) events has been proposed in a variety of conditions, including Rheumatoid Arthritis (RA). However, the mechanisms underlying this effect are still unknown. Since inflammation and Endothelial Progenitor Cells (EPCs) imbalance have been reported in RA patients to be related to CV disease, we wondered whether RDW could be linked to endothelial repair failure in RA.

TNFα polymorphism as marker of immunosenescence for rheumatoid arthritis patients.

Background: Expansion of CD4(+)CD28(null), a common feature of immunosenescence, which has been reported in rheumatoid arthritis (RA) patients, may also be associated with a CD4(+) imbalance. Although the increase of CD4(+)CD28(null) cells has been related to TNFα exposure, nothing is known about the possible role of genetic variants of this cytokine.

Methods: Participants were genotyped for TNFA rs1800629 (-308 G>A) and frequency of the CD4(+)CD28(null), regulatory T cells and Th1 cells subsets were quantified in peripheral blood samples by flow cytometry in 129 RA patients and 33 healthy controls.

Altered profile of circulating microparticles in rheumatoid arthritis patients.

Microparticles (MPs) could be considered biomarkers of cell damage and activation as well as novel signalling structures. Since rheumatoid arthritis (RA) is characterized by immune and endothelial activation, the main aim of the present study was to analyse MP counts in RA patients. Citrated-blood samples were obtained from 114 RA patients, 33 healthy controls (HC) and 72 individuals with marked cardiovascular (CV) risk without autoimmune manifestations (CVR).

Red cell distribution width is associated with cardiovascular risk and disease parameters in rheumatoid arthritis.

Objective: Since red cell distribution width (RDW) has been associated with cardiovascular (CV) disease and inflammation in several conditions, the main aim of this study was to evaluate its prognostic value in RA patients and its potential associations with clinical features.

Methods: The history of CV events was retrospectively reviewed in 160 RA patients and RDW was recorded at disease onset and 6 and 12 months after diagnosis to calculate the accumulated value [area under the curve (AUC) RDW] and change during the first year (ΔRDW). In addition, RDW was analysed in 110 patients with established disease in relation to clinical features.

Angiogenic T cells are decreased in rheumatoid arthritis patients.

Objective: The mechanisms underlying the increased cardiovascular risk (CVR) of rheumatoid arthritis (RA) patients remain unclear. Since the recently discovered angiogenic T cells (Tang) could have a role in endothelial repair through cooperating with endothelial progenitor cells (EPC), the main aim of this study was to analyse the Tang and EPC populations in relation to disease-specific features and traditional CVR factors.

Methods: Tang (CD3(+)CD31(+)CXCR4(+)) and EPC (CD34(+)VEGFR2(+)CD133(+)) populations were quantified by flow cytometry in peripheral blood samples from 103 RA patients and 18 matched healthy controls (HC).

Patients with psoriatic arthritis may show differences in their clinical and genetic profiles depending on their age at psoriasis onset.

Objectives: The age of psoriasis onset has an important impact on the clinical expression and heritability of psoriasis. Psoriasis characteristics according to the age at disease onset have been extensively studied. However, the impact of the age of psoriasis onset on psoriatic arthritis (PsA) features has not been analysed in depth.

[Biologic therapies different from the anti-TNFα therapy in psoriasis and psoriatic arthritis].

Psoriasis and psoriatic arthritis (PsA) are common conditions in the clinical practice of both dermatologists and rheumatologists. Both entities may cause an important loss in quality of life, and in the case of PsA, joint structural damage may arise over time. For these reasons, clinicians may be faced with the need for treating these cases with highly effective therapies, such as TNFα blocking agents, although these drugs may be paradoxically related with de novo onset (or exacerbation of previous lesions) of psoriasis or psoriasiform lesions.
