Background There are limited data regarding the contribution of advanced glycation end products in the presence of rheumatoid arthritis. We investigated whether serum Nɛ-carboxymethyllysine and pentosidine were related to the presence and the severity of rheumatoid arthritis. Methods Eighty patients with rheumatoid arthritis and 30 control subjects were included in a cross-sectional study. The severity of rheumatoid arthritis was assessed using the disease activity score for 28 joints. Serum Nɛ-carboxymethyllysine and pentosidine were measured by enzyme-linked immunosorbent assay. Results Serum Nɛ-carboxymethyllysine and pentosidine concentrations were significantly higher in patients with rheumatoid arthritis vs. control subjects ( P < 0.001). Serum Nɛ-carboxymethyllysine and pentosidine concentrations were significantly higher in rheumatoid arthritis patients with high disease activity vs. rheumatoid arthritis patients with moderate disease activity ( P < 0.001, P = 0.019, respectively). A multiple logistic regression analysis demonstrated that Nɛ-carboxymethyllysine was independently associated with the presence of rheumatoid arthritis (OR = 1.21, 95% CI: 1.05–1.39, P = 0.006). Furthermore, in a multivariate stepwise regression analysis, Nɛ-carboxymethyllysine was independently correlated with disease activity score for 28 joints (standardized β = 0.43, P = 0.001). Conclusion Serum Nɛ-carboxymethyllysine and pentosidine were increased during rheumatoid arthritis, and Nɛ-carboxymethyllysine was independently associated with the presence and the severity of rheumatoid arthritis.

Background. The contribution of methylglyoxal (MGO) and soluble receptor for advanced glycation end products (sRAGE) in the presence of rheumatoid arthritis (RA) is still unknown. We investigated whether serum MGO and sRAGE were related to the presence of disease activity in RA. Methods. 80 patients with RA and 30 control subjects were included in a cross-sectional study. The severity of RA was assessed using the disease activity score for 28 joints (DAS28). Serum MGO and sRAGE were measured by ELISA. Results. Serum MGO levels were significantly higher in patients with RA versus control subjects (P<0.001) and were increased in RA patients with higher disease activity versus RA patients with moderate disease activity (P=0.019). Serum sRAGE concentrations were significantly decreased in RA patients with higher disease activity versus RA patients with moderate disease activity and versus control subjects (P=0.004; P=0.002, resp.). A multiple logistic regression analysis demonstrated that MGO was independently associated with the presence of activity disease in RA (OR = 1.17, 95% CI: 1.02–1.31, P=0.01). Conclusion. Serum MGO and sRAGE levels are inversely related to the activity of RA, and MGO is independently associated with a higher disease activity of RA.

Background/aim: Nailfold video capillaroscopy is considered as a reliable method for evaluating peripheral microangiopathy in rheumatologic diseases. In this study, we aimed to demonstrate the utility of handheld dermatoscopy as an easy-to-use nailfold capillaroscopic instrument in patients with rheumatoid arthritis.Materials and methods: This cross-sectional study included patients with rheumatoid arthritis and healthy subjects. A handheld dermatoscopic examination of proximal nail fold was performed in each subject. The possible correlation of capillaroscopic findings with disease activity was evaluated using the disease activity score 28 (DAS28).Results: A total of 59 patients with rheumatoid arthritis and 60 healthy subjects were enrolled in the study. The presence of capillaryenlargement, avascular areas, capillary deformities, and capillary vascular anomalies in the group of patients showed a statistically significant difference when compared with the healthy subjects. No correlation was found between the nail fold capillaroscopic findings and DAS28 score.Conclusion: Hand-held dermatoscopy seems to be a useful technique in the evaluation of nail fold capillary changes. We suggest that in patients with rheumatoid arthritis, when capillaroscopic examination is needed, it can be evaluated using handheld dermatoscopy. Selected patients who showed findings using this method can be further examined with classical capillaroscopy to obtain more quantitative data.

Highlight:The correlation of IL-17 to disease activity by The Ankylosing Spondylitis Disease Activity Score C-Reactive Protein (ASDAS-CRP) was identified. IL-17 level is strongly correlated to disease activity in SpA patients. Abstract:IL-17 is a new cytokine involved in the pathogenesis of Spondyloarthritis (SpA). Recent studies show that IL-17 level correlates to disease activity, and it is used as a basis in treating SpA patients who do not respond to anti-TNF-α. This study identified the correlation of IL-17 to disease activity measured by The Ankylosing Spondylitis Disease Activity Score C-Reactive Protein (ASDAS-CRP). This study was a cross-sectional study involving SpA patients according to the 2009 ASAS criteria in Dr. Soetomo General Academic Hospital, Surabaya. Disease activity and IL-17 level were analyzed using Spearman correlation test to see the strength of correlation. Forty SpA patients showed mean age of 53.58 ± 9.28 years with a body mass index of 24.36 ± 3.23 kg/m2, ESR of 39.50 ± 18.76 mm/hour, clinically obtained Schober Test of 13.11 ± 1.22 cm, chest extension test of 1.45 ± 0.77 cm, and tragus-to-wall test 13.53 ± 1.99 cm. The median CRP and IL-17 were 0.3 (0.10-5.70) mg/dL and 9.30 (7.70-13.60) pg/dL, respectively. Based on the ASDAS-CRP system, the patients showed disease activities that fall into the category was high (62.5%), moderate (35%), and inactivity (2.5%). IL-17 level is strongly correlated to disease activity in SpA patients (p=0.000, r = 0.711).

BACKGROUND Rheumatoid arthritis (RA) is an autoimmune chronic inflammatory disorder. Uric acid is a by-product of purine metabolism, associated with diseases such as gouty arthritis, hypertension and cardiovascular disease (CVD). The association between serum uric acid concentrations and inflammation in patients with RA has been controversial. Some case reports suggest coexistence of gout and RA. Uric acid crystals can induce robust inflammation causing joint destruction and fibrosis. The purpose of this study was to estimate the serum uric acid levels in subjects with recently diagnosed rheumatoid arthritis and to correlate with disease activity. METHODS This cross-sectional study was done on 55 recently diagnosed RA subjects [American college of Rheumatology (ACR) criteria 2010] attending the rheumatology out-patient department (OPD) of a tertiary care institute in Chennai, Tamil Nadu. After clinical examination, evaluation of disease activity score (DAS), serum uric acid and rheumatoid factor (RF) were done. Data was analysed using Statistical Package for Social Sciences (SPSS trial version 28). Descriptive and inferential analysis was done. Correlation between serum uric acid levels and DAS was the main outcome. RESULTS The mean age was 41.51 ± 11.7 years. 87.3 % were females. Majority (58.2 %) were aged between 31 to 50 years. The mean duration of symptoms was 4.78 months. The mean serum uric acid level was 4.99 ± 1.2 mg/dl with 95 % C.I. of 4.66 to 5.31. The mean DAS was 5.34 ± 0.96. 56 % had high disease activity while only 44 % had moderate disease activity. 44 % were RF positive. There was no significant difference in serum uric acid levels across groups based on RF positivity and DAS severity respectively. There was no statistically significant correlation serum uric acid levels and DAS (-0.024, P value = 0.861). CONCLUSIONS Mean serum uric acid levels were elevated in recently diagnosed rheumatoid arthritis. Serum uric acid levels have no association with DAS and RF positivity in rheumatoid arthritis. Further studies are needed to investigate the role of specific treatment of elevated uric acid levels in rheumatoid arthritis independent of rheumatoid arthritis treatment.

Background: Rheumatoid Arthritis (RA) is an autoimmune, chronic, and systematic disease. It affects joints and bones. The exact etiology of RA is still unclear. Varied genetic and environmental factors have been associated with the increased risk for RA. Overactivation of Toll-Like Receptors (TLRs) could initiate the development of autoimmune diseases including RA. Objective: The aim of the study was to evaluate TLR2 gene expression in rheumatoid arthritis patients and investigate its correlation with the disease activity. Materials and Methods: This study included 60 patients and 20 healthy individuals. The patients were diagnosed with RA according to the 2010 American College of Rheumatology/ European League Against Rheumatism criteria (ACR/EULAR). All included subjects did not have any joint disorders and /or autoimmune diseases. RA disease activity was determined by the disease activity score of 28 joints. Whole blood was collected from all participants. Total RNA extraction was done. TLR2 mRNA expression was assessed by reverse transcription-PCR (RT-PCR). Results: TLR2 mRNA expression was found to be significantly higher in RA patients compared to healthy controls. Also, a strong positive correlation was found between TLR2 expression level and the disease activity score. A non significant positive correlation was found between TLR2 expression and serum Rheumatoid Factor (RF) level. Conclusion: TLR2 pathway may have an important role in RA pathogenesis and could be a new biomarker for diagnosis and monitoring disease activity.

Background: Rheumatoid arthritis (RA) is a common progressive chronic inflammatory autoimmune disease which affects mostly small joints, causing pain, swelling, deformity, and disability. Although progress has been made in exploring RA nature, still there is a lot to know about the disease pathogenesis, diagnosis, and treatment. Aim of the Work: To investigate the role of serum anti-carbamylated protein antibodies and 14-3-3η in the diagnosis of RA compared to rheumatoid factor (RF), anti-CCP antibodies, and highfrequency musculoskeletal ultrasound used to assess the disease activity and joint damage. Methods: Serum anti-carbamylated protein antibodies and 14-3-3η were measured using ELISA in 61 RA patients and 26 normal controls. RA Disease Activity Score (DAS 28), X-ray and musculoskeletal ultrasound (hands and feet), carotid ultrasound (Intima-Media Thickness IMT) were used in assessing the RA disease. Results: Anti-carbamylated protein antibodies were significantly elevated in RA patients 4.5 (4.1- 8.9 U⁄ml) compared to the control 3.2(1.9- 4.3 U⁄ml) (p< 0.001) but 14-3-3η showed no significant difference. There was a significant positive correlation between anti-carbamylated protein antibodies, 14-3-3η levels and disease activity score assessed by DAS 28, increased IMT measured by carotid duplex, total synovitis and total erosion score were assessed by musculoskeletal ultrasound. There was no correlation between RF and anti-CCP antibodies. Anti-carbamylated protein antibodies were found to have 66.7% sensitivity and 85.2% specificity in RA diagnosis, while 14- 3-3η had 51.9% sensitivity and 72.1% specificity. Conclusion: Anti-carbamylated protein antibodies and 14-3-3η have a high sensitivity and specificity in RA diagnosis and had a correlation with the disease activity and joint damage.
