Background. Neuropeptide Y (NPY) is a sympathetic neurotransmitter with effects on the regulation of inflammatory cells. The role of NPY on autoimmune inflammatory diseases such as rheumatoid arthritis (RA) is not completely understood. Therefore, we evaluate if NPY levels are markers of disease activity in RA and if there is a correlation between NPY levels and tumor necrosis factor-alpha (TNF-α), leptin, and interleukin 6 (IL-6) levels. Methods. Cross-sectional design, including 108 women with RA. We assessed disease activity by DAS28-ESR (considering active disease a score of ≥2.6). Serum NPY levels and anti-CCP2 antibody, TNF-α, IL-6, and leptin levels were quantified (ELISA). Results. Sixty-eight RA had an active disease (RA-active), and 40 were in remission (RA-remission). RA-active patients had higher NPY levels vs. RA-remission (22.8±13.6 vs. 17.8±10.3; p=0.04). NPY levels correlated with increased TNF-α levels (r=0.32, p=0.001). Leptin or IL-6 did not correlate with NPY levels. In the logistic regression analysis, NPY increased the risk of disease activity (OR: 1.04, 95% CI 1.006-1.09, and p=0.03). Conclusion. Higher NPY levels are an independent marker of disease activity in RA. This study encourages the quantification of NPY levels as a surrogate marker for RA-active. Future studies evaluating the role of NPY levels interacting with other proinflammatory cytokines are required.

Objective.Soluble CD14 (sCD14) is involved in innate immune responses and has been implicated to play a pathogenic role in inflammatory diseases including rheumatoid arthritis (RA). No studies have identified the specific factors that influence sCD14 expression in RA. We used cross-sectional data to evaluate the relationship of sCD14 concentrations in RA with measures of disease activity and severity. We hypothesized that sCD14 concentrations would be elevated in subjects with greater RA disease severity and markers of disease activity, compared to subjects with lower disease activity. We also examined whether well-defined polymorphisms in CD14 are associated with sCD14 expression in RA.Methods.Soluble CD14 concentrations were measured using banked serum from patients with RA (n = 1270) and controls (n = 186). Associations of patient factors including demographics, measures of RA disease activity/severity, and select CD14 single-nucleotide polymorphisms (SNP) with sCD14 concentration were examined in patients with RA using ordinal logistic regression.Results.Circulating concentrations of sCD14 were higher in patients with RA compared to controls (p < 0.0001). Factors significantly and independently associated with higher sCD14 levels in patients with RA included older age, being white (vs African American), lower body mass index, elevated high sensitivity C-reactive protein, and higher levels of disease activity based on the Disease Activity Score (DAS28). There were no significant associations of CD14 tagging SNP with sCD14 level in either univariate or multivariable analyses.Conclusion.Circulating levels of sCD14 are increased in RA and are highest in patients with increased levels of RA disease activity. In the context of RA, sCD14 concentrations also appear to be strongly influenced by specific patient factors including older age and race but not by genetic variation in CD14.

The aim of this research was to determine the clinical significance of tumor necrosis factor-alpha (TNF-alpha), IL-12, IL-15 and IL-18 in evaluation of the activity of rheumatoid arthritis. Cytokine concentrations in serum samples and synovial fluid were measured by immnnoenzymatic methods using kits for human interleukins and the Disease Activity Score 28 in 64 patients with active disease. The control group consisted of 25 subjects with arthritis of the knee and osteoarthrosis. Patients with rheumatoid arthritis have significantly high (p<0.01) concentrations of examined cytokines in relation to patients with osteoarthritis. By comparing concentrations in 30 patients with high, 14 patients with moderate and 20 patients with mild activity of rheumatoid arthritis, it was established that patients with high degree of disease activity have significantly high (p<0.01; p<0.05) concentrations of examined cytokines in the blood and synovial fluid in relation to patients with moderate and mild disease. We have concluded that cytokine concentrations are good indicators of the degree of rheumatoid arthritis activity. This research is a contribution to understanding the insufficiently known pathogenetic mechanisms of cytokines, especially IL-18, in active disease. .

ObjectivesTo investigate the relationship of socioeconomic status (SES) on an individual and country level with disease activity in rheumatoid arthritis (RA) and explore the mediating role of uptake of costly biological disease-modifying antirheumatic drugs (bDMARDs) in this relationship.MethodsData from a cross-sectional multinational study (COMOrbidities in RA) were used. Contribution of individual socioeconomic factors and country of residence to disease activity score with 28-joint assessment (DAS28) was explored in regression models, adjusting for relevant clinical confounders. Next, country of residence was replaced by gross domestic product (GDP) (low vs high) to investigate the contribution of SES by comparing R2 (model fit). The mediating role of uptake of bDMARDs in the relationship between education or GDP and DAS28 was explored by testing indirect effects.ResultsIn total, 3920 patients with RA were included (mean age 56 (SD 13) years, 82% women, mean DAS28 3.7 (1.6)). After adjustment, women (vs men) and low-educated (vs university) patients had 0.35 higher DAS28. Adjusted country differences in DAS28, compared with the Netherlands (lowest DAS28), varied from +0.2 (France) to +2.4 (Egypt). Patients from low GDP countries had 0.98 higher DAS28. No interactions between individual-level and country-level variables were observed. A small mediation effect of uptake of bDMARDs in the relationship between education and DAS28 (7.7%) and between GDP and DAS28 (6.7%) was observed.ConclusionsFemale gender and lower individual or country SES were independently associated with DAS28, but did not reinforce each other. The association between lower individual SES (education) or lower country welfare (GDP) with higher DAS28 was partially mediated by uptake of bDMARDs.

Background:Depression is thought to be common comorbidity in patients with rheumatoid arthritis (RA), which is one of the most frequent chronic inflammatory diseases.Objectives:This study aimed to screen for depression in RA patients, and study its relation to social and clinical parameters, as well as disease activity.Methods:Single-center cross-sectional study, involving patients with RA, according to ACR/EULAR criteria 2010, using the original Beck Depression Inventory (BDI) as a screening tool for depression: measures of 0–9 indicated that a patient was not depressed, 10–18 indicated mild to moderate depression, 19–29 indicated moderate to severe depression and 30–63 indicated severe depression.Results:Sixty-five patients were included (57 F / 8 M). The average age was 55 years [23-73]. The mean duration of the disease was 11.75 years [1-25]. Half of the patients had precarious socioeconomic conditions and no social security. Forty-two patients were unemployed. Seventeen percent of them experienced grief by losing a close family member. Both rheumatoid factor and anti-citrullinated peptides antibodies were positive in 83.1 % of cases. RA was erosive in 78.5% of cases, and deformed in 21.5 % of cases. Almost half of the patients (52.3 %) were followed for at least another chronic disease. Forty-eight percent of patients were on Methotrexate with an average weekly dose of 15.3 mg/week [10-22.5], 10% on Leflunomide, 10% on Sulfasalazine, and 45% on biotherapy. The analysis of BDI scores showed that 64.6 % of patients suffered from depression: mild to moderate in 35.4 % of cases, moderate to severe in 21.5% of cases and severe in 7.7% of cases. Depression was significantly associated with precarious socioeconomic conditions (p=0.018). A correlation between the BDI score and the Disease Activity Score (DAS28) as well as the Health Assessment Questionnaire was noted (p = 0.045 and p = 0.02, respectively). There were no statistically significant associations with the other studied data.Conclusion:Depression was frequent among RA patients. Our study suggests that better control of the disease may reduce the incidence of depression within this group of patients.References:[1]Beck, A.T., Ward, C., & Mendelson, M.

ObjectiveRheumatoid arthritis (RA) is a chronic systemic autoimmune disease that mainly targets joints. Monocytes and macrophages are critical in RA pathogenesis and contribute to inflammatory lesions. These extremely plastic cells respond to extracellular signals which cause epigenomic changes that define their pathogenic phenotype. Here, we interrogated how DNA methylation alterations in RA monocytes are determined by extracellular signals.MethodsHigh-throughput DNA methylation analyses of patients with RA and controls and in vitro cytokine stimulation were used to investigate the underlying mechanisms behind DNA methylation alterations in RA as well as their relationship with clinical parameters, including RA disease activity.ResultsThe DNA methylomes of peripheral blood monocytes displayed significant changes and increased variability in patients with RA with respect to healthy controls. Changes in the monocyte methylome correlate with DAS28, in which high-activity patients are divergent from healthy controls in contrast to remission patients whose methylome is virtually identical to healthy controls. Indeed, the notion of a changing monocyte methylome is supported after comparing the profiles of same individuals at different stages of activity. We show how these changes are mediated by an increase in disease activity-associated cytokines, such as tumour necrosis factor alpha and interferons, as they recapitulate the DNA methylation changes observed in patients in vitro.ConclusionWe demonstrate a direct link between RA disease activity and the monocyte methylome through the action of inflammation-associated cytokines. Finally, we have obtained a DNA methylation-based mathematical formula that predicts inflammation-mediated disease activity for RA and other chronic immune-mediated inflammatory diseases.

Abstract Background: Enthesitis related arthritis (ErA) is a specific subtype of juvenile idiopathic arthritis (JIA) which is often regarded as an undifferentiated form of juvenile spondyloarthritis (jSpA). Beside the arthritis of the peripheral joints, the crucial features of jSpA include enthesitis and/or arthritis of axial joints. Moreover, in adult onset spondyloarthritis gut is increasingly recognized as origin and/or target of inflammation, while the incidence of gut involvement in ErA patients is still largely unknown. The aim of this study was to assess the fCAL concentration, a surrogate marker of gut inflammation, in patients with various subtypes of JIA and non-inflammatory musculoskeletal conditions and to assess the correlation with various demographic, clinical, laboratory, imaging and treatment characteristics.Methods: This was a cross-sectional study involving 71 patients with various forms of JIA and other noninflammatory musculoskeletal diseases (NI-MSD). Along with detailed clinical and laboratory examination, fCAL and magnetic resonance imaging (MRI) of sacroiliac joints, thoracic and lumbar spine was routinely performed in all ErA patients, as well as in other patients who complained of abdominal and/or back pain, respectively. In all JIA patients, disease activity was measured using the juvenile arthritis (JADAS) or spondyloarthritis (jSpADA) disease activity score. Results: The median concentration of fCAL was highest in ErA subgroup (33.2 mg/kg, p=0.043), with a significant difference between patients with inactive and active disease (20.0 mg/kg vs 57.4 mg/kg, p=0.01), as well as between those with or without MRI signs of SIJ inflammation (22.6 mg/kg vs 54.3 mg/kg, p=0.048). In all patients, the fCAL concentration did not significantly differ among those receiving and not receiving NSAIDs (23 mg/kg vs 20 mg/kg, p=0.18), although weak correlation was found with the duration of the use (r=0.25, p=0.03).Conclusion: The (subclinical) gut inflammation might not be present only in adults with SpA, but also in children with undifferentiated forms of the jSpA, especially with active disease and/or MRI signs of SI inflammation.

Abstract Background Magnetic resonance index of activity (MaRIA) is composed of features independently associated with endoscopic disease activity and is surrogate marker of disease activity. The aim of this study was to evaluate correlation of global MaRIA (gMaRIA) with clinical and biochemical disease activity indices and diagnostic accuracy for active disease in patients with terminal ileum disease and ileocolonic disease. Methods This is a cross-sectional study which included 251 patients with diagnosed CD. Global MaRIA (gMaRIA) index was calculated on 6 bowel segments (the distal ileum, ascending, transverse, descending, sigmoid colon and rectum) using following parameters: bowel wall thickness, ulcers, edema and relative contrast enhancement. Disease activity was defined as combination of clinical and biochemical disease activity (CRP&gt;5 or HBI≥5). Disease extension was classified using Montreal classification (L1 ileum, L2 colon, L3 ileum and colon). Results This study included 251 CD patients [age 35 (25–47), 55.3% males, BMI 21.8 (18–25) kg/m2, median disease duration 7 (2–15) years]. Ileal disease (L1) was present in 84 (33.5%) and ileocolonic disease (L3) in 151 (60.1%) patients. Correlation of gMARIA with biochemical indices of disease activity (CRP) was r=0.48, p&lt;0.001 and with HBI r=0.33, p&lt;0.001. Diagnostic accuracy of gMARIA in defining active disease in patients with L1 disease was considerably high [AUC 0.83 (95%CI 0.72–0.91)]. On the other hand, diagnostic accuracy in defining active disease in patients with L3 disease was good [AUC 0.71 (95%CI 0.62–0.79)], which is lower compared to L1 disease. In surgically naïve patients diagnostic accuracy of L1 disease was [AUC 0.88 (95%CI 0.72–0.96)], and for L3 disease [AUC 0.78 (95%CI 0.64–0.89)]. Conclusion Global MaRIA index showed higher diagnostic accuracy in detecting clinically and biochemically active disease in terminal ileum compared to ileocolic disease. These results emphasize the important role of magnetic resonance enterography in monitoring disease activity in patients with isolated ileal disease. Global MaRIA score correlates better with biochemical disease activity compared to clinical disease activity, which points out to the significance of biochemical remission.

Background: Rheumatoid Arthritis (RA) is the most common type of chronic inflammatory arthritis with unknown etiology marked by a symmetric, peripheral polyarthritis. Calprotectin also can be used as a biomarker of disease activity in inflammatory arthritis and other autoimmune diseases. Objective: In this study, we evaluated the association between serum calprotectin level and severity of RA activity. Methods: A cross-sectional study was conducted on 44 RA patients with disease flare-up. Serum samples were obtained from all patients to measure calprotectin, ESR, CRP prior to starting the treatment and after treatment period in the remission phase. Based on Disease Activity Score 28 (DAS28), disease activity was calculated. Results: Of 44 RA patients, 9(20.5%) were male and 35(79.5%) were female. The mean age of our cases was 53±1.6 years. Seventeen (38.6%) patients had moderate DAS28 and 27(61.4%) had high DAS28. The average level of calprotectin in the flare-up phase was 347.12±203.60 ng/ml and 188.04±23.58 ng/ml in the remission phase. We did not find any significant association between calprotectin and tender joint count (TJC; P=0.22), swollen joint count (SJC; P=0.87), and general health (GH; P=0.59), whereas significant associations were found between the calprotectin level and ESR (p=0.001) and DAS28 (p=0.02). The average calprotectin level in moderate DAS28 (275.21±217.96 ng/ml) was significantly lower than that in high DAS28 (392.4±183.88 ng/ml) (p=0.05). Conclusion: We showed that the serum level of calprotectin can be a useful and reliable biomarker in RA activity and its severity. It also can predict treatment response.
