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.

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.

Objectives:To compare the efficacy of Disease Activity Score (DAS)-driven therapy and routine care in patients with recent-onset rheumatoid arthritis.Methods:Patients with recent-onset rheumatoid arthritis receiving traditional antirheumatic therapy from either the BeSt study, a randomised controlled trial comparing different treatment strategies (group A), or two Early Arthritis Clinics (group B) were included. In group A, systematic DAS-driven treatment adjustments aimed to achieve low disease activity (DAS ⩽2.4). In group B, treatment was left to the discretion of the treating doctor. Functional ability (Health Assessment Questionnaire (HAQ)), Disease Activity Score in 28 joints (DAS28) and Sharp/van der Heijde radiographic score (SHS) were evaluated.Results:At baseline, patients in group A (n = 234) and group B (n = 201) had comparable demographic characteristics and a mean HAQ of 1.4. Group A had a longer median disease duration than group B (0.5 vs 0.4 years, p = 0.016), a higher mean DAS28 (6.1 vs 5.7, p<0.001), more rheumatoid factor-positive patients (66% vs 42%, p<0.001) and more patients with erosions (71% vs 53%, p<0.001). After 1 year, the HAQ improvement was 0.7 vs 0.5 (p = 0.029), and the percentage in remission (DAS28 <2.6) 31% vs 18% (p<0.005) in groups A and B, respectively. In group A, the median SHS progression was 2.0 (expected progression 7.0), in group B, the SHS progression was 1.0 (expected progression 4.4).Conclusions:In patients with recent-onset rheumatoid arthritis receiving traditional treatment, systematic DAS-driven therapy results in significantly better clinical improvement and possibly improves the suppression of joint damage progression.

Abstract Objective To assess the utility of Patient Based Disease Activity Score 2 (PDAS 2) in assessing the disease activity in Rheumatoid arthritis (RA). Methods A prospective cohort study was conducted on 80 patients of RA. The demographic and clinical characteristics of the patients were recorded. They were assessed for disease activity using “Disease Activity Score 28” (DAS 28), “Clinical Disease Activity Index” (CDAI) and PDAS 2 score at baseline (M0), at 2 months (M2) and at 4 months(M4) while they were on treatment. Data was analyzed for correlation of PDAS-2 with other scores and internal reliability. P < 0.05 was considered for statistical significance. Results The mean age was 40.13\(\pm\) 11.74 years with 70 females and 10 males. There was significant reduction in DAS28, CDAI and PDAS 2 score over 4 month follow up (all scores’ p values < 0.001). Internal reliability (as assessed by Cronbach’s Alpha) of PDAS 2 was 0.578. PDAS 2 showed significant correlation with DAS28 at M0, M2 and M4 (r = 0.792, 0.757 and 0.669 respectively, p value < 0.001) and CDAI (r = 0.861, 0.832 and 0.695 respectively, p value < 0.001). Overall there was a significant agreement between DAS 28 and PDAS 2 (K = 0.788,p < 0.001) and between CDAI and PDAS 2 (K = 0.766,p < 0.001). Conclusion PDAS-2 score can be routinely used in the clinical practice owing to its correlation with DAS-28/CDAI and because of the advantage that it assessed the patients’ daily living activities.

Objective.This article reports 1-year clinical outcomes in the subgroup of patients with rheumatoid arthritis in the Abatacept study to Gauge Remission and joint damage progression in methotrexate-naive patients with Early Erosive rheumatoid arthritis (AGREE) who achieved radiographic nonprogression at the end of the double-blind phase.Methods.Patients who achieved radiographic nonprogression (change from baseline in total Sharp score ≤ 0 at 12 months) with abatacept plus methotrexate (MTX) or MTX alone were eligible for this analysis. Clinical outcomes were remission, defined by 28-joint Disease Activity Score (DAS28) using C-reactive protein (CRP), low Disease Activity Score (LDAS), American College of Rheumatology (ACR) scores, physical function (Health Assessment Questionnaire), and tender and swollen joint counts. Safety was assessed at each visit.Results.Patients in the abatacept plus MTX and MTX monotherapy groups had similar baseline characteristics and were similar to the overall study population. The proportion of patients who achieved DAS28 (CRP) remission or LDAS was greater with abatacept plus MTX vs MTX alone [43.2% vs 22.7% (p < 0.001) and 57.4% vs 40.6% (p = 0.008), respectively]. More patients receiving abatacept plus MTX achieved key ACR responses, including major clinical response (27.3% vs 11.9%; p < 0.001). Safety profiles were similar in both treatment groups.Conclusion.More MTX-naive patients with early RA who achieved radiographic nonprogression taking abatacept plus MTX also achieved DAS28 (CRP)-defined remission and LDAS compared with patients who received MTX alone, supporting the use of abatacept as a first-line biologic in combination with disease-modifying antirheumatic drugs.

Abstract Background Rheumatoid arthritis (RA) is a progressive, systemic autoimmune disorder characterized by articular and extra-articular manifestations. The lung is commonly a site of extra-articular disease. The lung manifestations of RA vary and may include airways, parenchymal, vascular, and pleural disease. Manifestations of lung disease in RA typically follow the development of articular disease. Methotrexate (MTX)has shown efficacy for the treatment of several diseases, especially RA. Methotrexate has also been implicated as a causative agent in interstitial lung disease. Objective to find any association between MTX intake and lung abnormalities in RA patients. Patients and Methods This study included sixty adult RA patients, recruited from Ain Shams University Hospitals. Patients were divided into thirty patients on MTX therapy, and another thirty patients on non-methotrexate therapy. All underwent history, clinical examination, chest examination, evaluation of RA by modified disease activity score 28 (DAS 28) and pulmonary function tests(PFT). Results The age of patients receiving MTX ranged from 35-65 years and the non-MTX group was 35-57 years with a mean ±SD of 47.733±5.265 and 40.700 ±5.187, respectively. Male to female ratio of MTX group was about 1:3, while Non MTX group was about 1:9.There was no significant difference regarding age and sex. There was no difference between both group regarding modified DAS score and chest manifestations. There was no difference in PFT findings between patients on high or low dose of MTX therapy .Similarly, no association was found between disease activity score and PFT findings in both groups. On the other hand, a significant association between chest symptoms and PFT, P value&lt;0.05 . Also a strong significant association was found between anticitrullinated protein antibodies (ACPA) status and PFT in both group, p value &lt;0.05. Conclusion MTX treatment was not associated with an increased risk of RA-ILD diagnosis. On the contrary, evidence showed that MTX may delay the onset of ILD. There seems no reason to confuse the association of MTX and hypersensitivity pneumonitis with the onset of RAILD.ACPA antibody is considered a major risk factor in RA-ILD, ACPA titers constitute an independent factor associated not only with the presence but also with the severity of RA-ILD

Objective.To determine whether a multibiomarker disease activity (MBDA) score predicts radiographic damage progression in the subsequent year in patients with early rheumatoid arthritis.Methods.There were 180 serum samples available in the BeSt study (trial numbers NTR262, NTR 265): 91 at baseline (84 with radiographs available) and 89 at 1-year followup (81 with radiographs available). Radiographs were assessed using the Sharp/van der Heijde Score (SvdH). Twelve serum biomarkers were measured to determine MBDA scores using a validated algorithm. Receiver-operating curves and Poisson regression analyses were performed, with Disease Activity Score (DAS) and MBDA score as independent variables, and radiographic progression as dependent variable.Results.At baseline, MBDA scores discriminated more between patients who developed radiographic progression (increase in SvdH ≥ 5 points) and patients who did not [area under the curve (AUC) 0.767, 95% CI 0.639–0.896] than did DAS (AUC 0.521, 95% CI 0.358–0.684). At 1 year, MBDA score had an AUC of 0.691 (95% CI 0.453–0.929) and DAS had an AUC of 0.649 (95% CI 0.417–0.880). Adjusted for anticitrullinated protein antibody status and DAS, higher MBDA scores were associated with an increased risk for SvdH progression [relative risk (RR) 1.039, 95% CI 1.018–1.059 for baseline MBDA score; 1.037, 95% CI 1.009–1.065 for Year 1 MBDA score]. Categorized high MBDA scores were also correlated with SvdH progression (RR for high MBDA score at baseline 3.7; low or moderate MBDA score as reference). At 1 year, high MBDA score gave a RR of 4.6 compared to low MBDA score.Conclusion.MBDA scores predict radiographic damage progression at baseline and during disease course.
