Abstract BackgroundTrue remission is the ultimate goal for rheumatoid arthritis (RA) therapy. Our aim was to investigate the relationship between serum levels of rheumatoid factor (RF) and anti-cyclic citrullinated peptides (Anti-CCP) and ultrasonographic (US) findings in Egyptian RA patients in clinical remission.MethodsUsing data from a cross-sectional study on 50 RA patients in clinical remission or low disease activity (LDA) as defined by disease activity score (DAS28-ESR) cutoff points, performed in Alexandria University Hospital; we analyzed statistical relationships and correlations between RF, Anti-CCP) and Gray Scale (GS) and Power Doppler (PD) US using US7 score. US remission was defined as on a GS ≤ 1 and PD = 0. ResultsAmong 34 patients in clinical remission, 61.8% (21) of patients in clinical remission were in ultrasonographic remission, and 38.2% (13) of patients in clinical remission had subclinical ultrasonographic activity. Patients in clinical remission with US remission had significantly higher Anti-CCP (p= 0.006) but not RF (p= 0.086), than those in clinical remission with US subclinical activity. Anti-CCP positively correlated with synovitis score by power Doppler US (PDUS) (rs= 0.553, p= 0.001), and tenosynovitis/paratenonitis score by gray scale US(GSUS) (rs=0.389, p= 0.023).ConclusionWe demonstrated that patients in clinical RA remission with subclinical US activity had higher serum levels of Anti-CCP, but not RF. Such an association should guide further treatment decisions for those patients.

We investigated the importance of the baseline expression of genes involved in energy generation, as prognostic biomarkers of the treatment response to tofacitinib in patients with rheumatoid arthritis (RA). Peripheral blood samples were obtained from 28 patients with RA who received 3 months of tofacitinib therapy from 26 healthy controls. Clinical response was evaluated based on the disease activity score, the erythrocyte sedimentation rate (DAS28-ESR), and the serum levels of ACPA, RF, CRP, and ESR. Clinical remission was assessed based on DAS28 score <2.6. Protein concentrations were measured using ELISA. Total RNA isolated from whole blood was used for gene expression analysis using quantitative RT-PCR. All patients were diagnosed with Steinbrocker’s radiographic stage II-III at baseline, and most showed erosive arthritis with ACPA and RF positivity. Tofacitinib treatment significantly decreased the disease activity. Upon study completion, seven patients showed remission. Before and after TOFA therapy, a significantly higher expression of succinate dehydrogenase and pyruvate kinase genes was observed in all the examined patients compared to healthy subjects. However, the pre-therapy expression of these genes and corresponding proteins was significantly (p ≤ 0.05) lower in patients who showed remission than in other patients with RA. Moreover, we observed that, during follow-up, patients who developed remission showed an increasing trend in the expression of the examined genes, whereas the others showed some decreases in gene expression, although this was not statistically significant. We concluded that, compared with RA patients maintaining persistent moderate or high disease activity, those with clinical remission following tofacitinib treatment showed a significantly lower baseline expression of genes involved in energy generation.

Background: Tumor necrosis Factor-α (TNF-α) is encoded and controlled by TNF-α gene, which is involved in rheumatoid arthritis (RA) susceptibility. This research aimed to identify genetic variations of TNF-α (G308A) and to establish its association with inflammatory markers in Rheumatoid Arthritis predisposition. Methods: In the present study, fifty RA patients and fifty volunteers were involved and evaluated for the C-reactive protein, rheumatoid factor, and TNF-α were estimated by ELISA, Erythrocyte Sedimentation Rate (ESR) by Wintergreen method and for TNF-α-308 G>A polymorphism by polymerase chain reaction with amplification refractory mutation system (PCR-ARMS). Results: The CRP, RF, ESR and TNF-α were significantly elevated in RA patients relative to controls. The serum level TNF-α was also significantly elevated in female patients and in patients ≥50 years. Analysis of TNF-308 gene polymorphism revealed that GG genotypes were more prevalent in RA patients than in the healthy individuals and that GG genotype may be a potential factor to RA. The G allele was more common in RA than in the control. Elevated TNF-α serum levels were significantly associated the GG genotype and functional disability in RA patients. Conclusion: TNF-α promoter 308polymorphism GG genotype may be considered as a risk factor for RA and the TNF-α serum level was significantly related to the functional disability in the disease.

Aim: The aim of this study was to investigate the effect of dietary education on cardiovascular risk factors in patients with rheumatoid arthritis. Method: In this randomized clinical trial, 112 patients with rheumatoid arthritis were randomly assigned into two groups, intervention and control. Dietary education was provided for the intervention group in 4 sessions; anthropometric measurements, serum levels of RF, triglycerides, cholesterol, HDL, LDL, and fasting blood sugar were measured before and three months after intervention. Data was analyzed using SPSS software and appropriate statistical tests. Results: The mean of total cholesterol (p <0.001), triglycerides (p = 0.004), LDL (p <0.001), systolic blood pressure (p = 0.001), diastolic blood pressure (p = 0.003), FBS and BMI (p <0.001) were decreased significantly in the intervention group after education compared the control group. Conclusion: Traditional care for rheumatoid arthritis patients is not enough. Patients need more education in order to improve their situation.

Background:Sustained remission (SR) is an ultimate treatment goal in the management of patients with rheumatoid arthritis (RA) (1) and is associated with better RA prognosis, reflected by the quality of life, physical function and radiographic progression (2).Objectives:To investigate the prevalence and predictors of SR in RA patients.Methods:A longitudinal prospective study of patients with RA. At the inclusion, the patients were in remission DAS28 ESR≤ 2.6 for at least 6 months. A B-mode and power doppler (PD) ultrasound of 42 joints and 20 tendons was performed. Synovial hypertrophy (SH) and tenosynovitis in B-mode and PD were defined and scored from 0 to 3 using the OMERACT. The CDAI, SDAI, Boolean remission criteria, the health assessment questionnaire (HAQ) and the radiological Sharp score were calculated. Then, the DAS28 erythrocyte sedimentation rate (ESR) was evaluated at 6 and 12 months. SR was defined as the persistence of a DAS28 ESR≤2.6 at 6 or 12 months without any change in RA therapy during the follow-up. Unstable remission (UR) was defined either as DAS28 ESR > 2.6 at 6 or 12 months or an increase in RA therapy because of a relapse during the follow-up.Results:At baseline, thirty-seven patients were included. At 6 and 12 months, 28 and 24 patients completed follow-up, respectively. In decreasing order, Boolean remission (92.2%), DAS28ESRremission (85.7%), SDAI remission (85%) and CDAI remission (83.3%) achieved SR at 6 months. At 12 months, SR was found in 100% in Boolean remission, 87.5% in SDAI remission, 86.7% in CDAI remission and in 79.7% in DAS28 ESR remission. At 6 months, only the ESR (17mm/1h in SR versus 32 mm/1h in UR, p=0.04) was associated with SR. The disease duration, remission duration, swollen and tender joints, DAS28ESR, HAQ, rheumatoid factor, radiological Sharp score and ultrasound parameters weren’t associated with SR. At 12 months, the squeeze test (15% in SR vs 80% in UR, P=0.01), the ESR (15 mm/1h in SR versus 30 mm/1h in UR, p=0.03), the Boolean remission (61.1% in SR versus 0% in UR, p=0.04) and the DAS28ESR (mean: 1.8 in SR versus 2.5 in UR, P=0.01) were associated with SR. However, no association was found with radiological Sharp score and ultrasound parameters. On multivariate analysis, the ESR (OR=1.13, CI95%=1.01-1.2, p=0.03) and the Squeeze test (OR=21.3, CI95%=1.7-263, p=0.01) were predictors of SR, at 12 months.Conclusion:At 6 and 12 months, 79.7%-85.7% of patients in DAS28 ESR remission achieved sustained remission, respectively. Boolean and DAS28 ESR remission were associated with SR. Unlike DAS28 ESR, Boolean remission seems to reflect more the SR. The squeeze test and the ESR were predictors’ factor. However, the radiological and the ultrasound parameters didn’t show any association.References:[1]Ajeganova S, Huizinga T.

Abstract Objectives To examine whether serum antibodies against selected periodontal pathogens are associated with early symptoms of rheumatoid arthritis (RA) development in healthy individuals at risk of developing the disease. Methods Within an ongoing study cohort of first-degree relatives of patients with RA (RA-FDRs), we selected four groups corresponding to specific preclinical phases of RA development (n = 201). (1) RA-FDR controls without signs and symptoms of arthritis nor RA-related autoimmunity (n = 51); (2) RA-FDRs with RA-related autoimmunity (n = 51); (3) RA-FDRs with inflammatory arthralgias without clinical arthritis (n = 51); (4) RA-FDRs who have presented at least one swollen joint (“unclassified arthritis”) (n = 48). Groups were matched for smoking, age, sex and shared epitope status. The primary outcome was IgG serum levels against five selected periodontal pathogens and one commensal oral species assessed using validated-in-house ELISA assays. Associations between IgG measurements and preclinical phases of RA development were examined using Kruskal-Wallis or Mann-Whitney tests (α = 0.05). Results None of the IgGs directed against individual periodontal pathogens significantly differed between the four groups of RA-FDRs. Further analyses of cumulated IgG levels into bacterial clusters representative of periodontal infections, revealed significantly higher IgG titers against periodontopathogens in anti-citrullinated protein antibodies (ACPA)-positive RA-FDRs (p = 0.015). Current smoking displayed a marked trend towards reduced IgG titers against periodontopathogens. Conclusion Our results do not suggest an association between serum IgG titers against individual periodontal pathogens and specific preclinical phases of RA development. However, associations between cumulative IgG titers against periodontopathogens and the presence of ACPAs suggest a synergistic contribution of periodontopathogens to ACPA development.

Background:Rituximab (RTX) is a chimeric monoclonal antibody against CD20. There is a paucity of studies done with RTX biosimilars. This is a Retrospective and Observational study from January 2018 to December 2019 done in the Department of Clinical Immunology & Rheumatology, Sri Ramachandra Institute of Higher Education and Research, Chennai, India.Objectives:1.To find the effects of varying doses of RTX in attaining clinical remission in RA.2.To find if CD19, CD20 & IgG help in identifying impending flare & if these levels help in deciding the timing of the next dose of RTX.Methods:Rheumatoid arthritis (RA) cases who were given Rituximab from January 2018 were selected. Clinical Response at 6 & 12 months & wherever feasible at 18 & 24 months was assessed by Simplified Disease Activity index (SDAI). RTX initial dose was given at 0 and 14 days followed by fixed dose at six months interval.CD19, CD20 B cell count, IgG levels were tested in patients in whom it was feasible at baseline & 6 months (select patients at 12,18 &24 months). Patients were divided in to 5 groups (DMARD naïve, DMARD resistant & Interstitial Lung disease (ILD) [Lung involvement>20% in Computed Tomography (CT)]) and (500mg & 1g). Patients were divided into three clinical groups, (DMARD naïve, DMARD resistant & Interstitial Lung disease (ILD) [Lung involvement>20% in Computed Tomography (CT)]) and two treatment groups (500mg & 1g) based on clinical indication for RTX and dose of RTX, respectively. In patients with ILD, CT scan & FVC were compared at baseline & 12 months.Results:29 patients (seropositive 28 (RF/Anti CCP/BOTH+VE), seronegative 1) were given RTX for RA over a 2-year period of which 12 had CD19, CD20 & IgG tested. Mean SDAI reduction from baseline to 6 months post treatment was 30%, 32% & 14% while complete remission (SDAI<3.3) was attained in 100%, 18% & 20% in DMARD naïve, DMARD resistant & ILD groups, respectively. CD19, CD20 & IgG reduced from 18.6%, 18.4% & 18.53g/L to 3.7%,3.7% & 9.7g/L respectively FVC improved from 62.4% to 67% at 12. The percentage of patients with lung involvement >20% reduced from 53.3% to 46.7%. Flare was observed in one patient who received 500mg RTX. CD19, CD20 & IgG levels increased from 7.9%, 8% & 9.8g/L to 27%, 25% & 13g/L respectively. 3 patients in the 1g group were followed up at 12,18 & 24 months. In these patients there were no flares or worsening symptoms. 1 patient was double negative for RF & Anti CCP and this patient did not attain clinical remission even after 2 doses of 1g RTX.Conclusion:[1]Patients with early arthritis (diagnosis made within 1 year) and who were DMARD naïve had an excellent response to Rituximab.[2]Complete remission was observed in more patients the 1g compared to 500mg group.[3]Reduction in CD19 & CD20 was associated with significant reduction in the SDAI score.[4]There was no significant reduction of CD19 & CD20 with 500mg dose of Rituximab where either a partial remission or mild flare was observed.[5]There was reduction in the lung involvement to less than 20%(CT) in few patients with 1g dose.[6]Double negative Rheumatoid arthritis poorly responded to Rituximab.[7]The positive effects of 1g Rituximab could be noted up to 24 months.[8]Flare of RA was associated with significant increase in CD19 & CD20.Disclosure of Interests:None declared
