Rheumatoid arthritis is an inflammatory rheumatic disease with unknown etiology characterized by symmetric, chronic and erosive arthritis (synovitis) of the peripheral joints and systemic inflammatory involvement of the viscera. Lung pathology, including interstitial lung disease, is one of the common extra-articular manifestations at the гheumatoid arthritis. The leading diagnosis method of interstitial lung disease is a computed tomography high resolution, which allows to identifying interstitial lung changes in 70% of the cases. The study of prognosis in patients with rheumatoid arthritis interstitial lung disease has been the subject of several studies in the past decade. In most studies it was stated that the average life expectancy from diagnosis is around 3 years. This work is devoted to study of interstitial lung disease as one of the most frequent extra-articular ma-nifestations of rheumatoid arthritis. The authors defined the significance of computed tomography high resolu-tion for the diagnosis of pulmonary interstitial lung changes at rheumatoid arthritis. They give comparative clini-cal and immunological, instrumental characteristics of rheumatoid arthritis patients with interstitial lung disease and without it. The role of smoking and positivity of anti-cyclic citrullinated peptide (anti-CCP) according to antibodies are determined as risk factors of interstitial lung disease development in patients with rheumatoid arthritis. The interrelation of the X-ray tomography symptom of interstitial lung disease "ground glass opacity" with the activity and duration of rheumatoid arthritis is revealed. "Ground glass opacity" symptom is associated with high index of DAS28 in patients with rheumatoid arthritis with interstitial lung disease.

Abstract Introduction Interstitial lung disease in rheumatoid arthritis (RA-ILD) is an extra-articular involvement that impairs the prognosis and for which there is still no well-coded treatment. The aim of this study was to evaluate abatacept (ABA) effectiveness and safety in patients with RA-ILD. Methods RA-ILD patients who started ABA treatment were consecutively enrolled. Chest high-resolution computed tomography (HRCT), clinical, laboratory and respiratory function variables were collected at baseline and after 18 months of ABA treatment. HRCT abnormalities were evaluated using a computer-aided method (CaM). ABA response was established based on the change in the percentage of fibrosis evaluated at HRCT-CaM, dividing patients into “worsened” (progression ≥ 15%), “improved” (reduction ≥ 15%), and “stable” (changes within the 15% range). The multivariate regression model was used to assess the associations between RA characteristics and ABA response. Results Forty-four patients (81% women, mean age 59.1 ± 8.0, mean disease duration of 7.5 ± 3.1 years) were studied. Five patients (11.4%) showed RA-ILD progression, 32 patients (72.6%) were considered stable, and 7 patients (16.0%) showed an RA-ILD improvement. The proportion of current smokers was significantly different between “worsened” patients, respect to those defined as "improved/stable” (p = 0.01). Current smoking habit (p = 0.005) and concomitant methotrexate treatment (p = 0.0078) were the two variables related to RA-ILD progression in multivariate regression analysis. Conclusion Treatment with ABA is associated with a RA-ILD stability or improvement in the 88.6% of patients. Current smoking habit and concomitant treatment with methotrexate are the modifiable factors associated with RA-ILD worsening. Key Points• Abatacept plays a favourable role in the control of RA-ILD, with a significant worsening in only 11.4% of patients during a 18-month follow-up period.• The predictive variables related to RA-ILD progression during abatacept therapy are the concomitant treatment with methotrexate and current smoking habit.

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

ABSTRACT Objectives Interstitial lung disease (ILD) associated with the antimelanoma differentiation-associated protein 5 (anti-MDA5) antibody is a rapidly progressive disease that requires timely, aggressive treatment. However, prompt diagnosis is difficult due to the longer time required for antibody detection. This study described the computed tomography (CT) findings of anti-MDA5 antibody-positive ILD (anti-MDA5-ILD). Methods CT findings of 20 patients (7 men, 13 women; mean age, 53.6 ± 13.5 years) with anti-MDA5-ILD were retrospectively reviewed. All patients had clinical diagnoses of dermatomyositis, and 14 patients presented with amyopathic findings. Results Bilateral ground-glass attenuation, air-space consolidation, and reticular shadows were observed in 20 (100%), 15 (75%), and 3 (15%) patients, respectively. The spread of air-space consolidation was 6.0 ± 5.6% (mean ± standard deviation). Univariate analysis revealed that high Krebs von den Lungen-6, high spread of consolidation, low partial pressure of oxygen, and low forced vital capacity were significant predictors for poor survival. The final radiological diagnoses were nonspecific interstitial pneumonia and organising pneumonia (OP) in 2 (10%) and 16 (80%) patients, respectively. Further, 30% of OP patients showed fibrosis. Conclusion The characteristic CT findings of patients with anti-MDA5-ILD were ground-glass attenuation, air-space consolidation, and less reticulation. These CT findings were compatible with those of OP.
