Background and aims: Assessments of disease activity in rheumatoid arthritis plays an important role in determining treatment plans and patient response to treatment. The aims of this study was to describe the power Doppler ultrasound features of wrist joints in patients with rheumatoid arthritis and evaluate role of power Doppler ultrasoundin assessing disease activity in patients withrheumatoid arthritis. Material and method: This present study included 30patients diagnosed with rheumatoid arthritis according to the 2010 ACR/EULAR classification criteria, who were admitted in the period July 2017 to April 2018 in Department of Nephrology and Rheumatology, Hue Central Hospital. All patients were physical examination, laboratory investigations, assessment disease activity score in 28 joints using CRP (DAS28-CRP), clinical disease activity index (CDAI), simplified disease activity index (SDAI). Grey scale ultrasound and power Doppler ultrasound were used to assess synovitis, effusion and tenosynovitis and synovial vascularity of 60 wrist joints. Power Doppler was graded using a validated semiquantitative scroring system, which consists of scale of 0-3. Result: Twenty-seven wrist joints (45.0%) had synovitis in grey scale ultrasound. Thirty-seven wrist joints (61.7%) had a power doppler signal, 18.3% had grade 1 (low), 21.7% had grade 2 (moderate) and 21.7% had grade 3 (high). Level of angiogenesis in PDUS with semiquantitative scroring systemweresignificantly correlated with tender joint count, swollen joint count, global VAS, CRP and CDAI, SDAI, DAS28-CRP. Conclusions: Power Doppler ultrasound of wrist joints could be used as a non-invasive and feasible method to assessing disease activity in patients with rheumatoid arthritis. Key words: rheumatoid arthritis, power Doppler ultrasound

Background:Baricitinib, an oral Janus kinase (JAK) 1-2 inhibitor, is currently used among biologic DMARDs (bDMARDs) after the failure of methotrexate (MTX) in rheumatoid arthritis (RA). Power Doppler ultrasound (PDUS) is a promising, non-invasive imaging method to assess synovitis in RA: results from numerous studies suggest that it provides additional information to clinical and conventional radiographic examinations.Objectives:The main objective of our study was to evaluate short-term efficacy of Baricitinib in reducing synovitis, using the composite semi quantitative scale (0–3 grades) PDUS synovitis score, developed by the Outcome Measures in Rheumatology– European League Against Rheumatism (OMERACT– EULAR)-Ultrasound Task Force. Moreover both synovial hyperplasia and intrasynovial power Doppler (PD) signal were also scored as single components/parameters on 0-3 scales. Secondary objective was to assess the concordance between patient reported outcomes (PROs), markers of inflammation, physical examination and US.Methods:We enrolled 30 patients fulfilling 2010 ACR and EULAR criteria for RA. All patients had failed at least one anti-TNF. Each patient was prescribed Baricitinib 4 mg/daily at T0, in addition to MTX and/or oral steroids at a dosage ≤ 7, 5 mg/day of Prednisone or equivalent, at T’. All patients were evaluated at baseline (T0) and then after one month (T1), 3 months (T2) and 6 months (T3) of treatment. Swollen and tender joints (out of 28)were evaluated and recorded, as well as patient (PGA) and physician global assessment (PhGA) and pain, expressed in a visual analog scale (VAS). Disease activity was evaluated at each visit using DAS28 (Disease activity score 28), CDAI (Clinical disease activity index)and SDAI(Simplified disease activity index), accompanied by a complete blood count, Erythrocyte sedimentation rate (ESR) and C- reactive protein (CRP) collection. Statistical analysis was performed using GraphPad version 9.0.0. PDUS examination, was carried out by two rheumatologists (PF and CB) blinded to clinical conditions of the patients, using an Esaote Mylab Twice (Genoa, Italy), equipped with a high-frequency (6-18 MHz) linear probe. With standardised Doppler parameters (pulse repetition frequency between 500-750 Hz; Doppler frequency between 7–11.1 MHz). PDUS was performed at each visit bilaterally for 22 joint sites [MCPs 1–5, proximal interphalangeal joints (PIPs) 1–5, wrist, elbow, glenohumeral, knee, tibiotalar, talonavicular and calcaneocuboidal and metatarsophalangeal joints (MTPs) 1–5] for a total of 44 joints for each patient.Results:we observed a reduction of VAS pain (T0 vs, T6<0,0001) PDUS composite score (T0 vs. T6 p<0,0001), Power Doppler (T0 vs. T6 p<0,0001) synovial hyperplasia (T0 vs. T6 p=0,0002), CRP (T0 vs. T6 p<0,0001) and ESR (T0 vs. T6 p <0,0001) was observed in our patients. Accordingly, DAS-28, CDAI and SDAI displayed a significant reduction too (DAS-28: T0 vs. T6 p< 0, 0001; CDAI: T0 vs. T6 p< <0, 0001; SDAI: T0 vs. T6 p= 0, 0003).Conclusion:We investigated the efficacy of Baricitinib in real life, evaluating both from a clinimetric and ultrasound point of view. Baricitinib, demonstrated a significant parallel and fast improvement in VAS, PDUS and CRP was found at follow up assessment as early as one month of therapy. In conclusion, these results demonstrated the short term efficacy of Baricitinib 4mg for up to 6 months and providing a prompt improvement of PROs within the first weeks of treatment.Figure 1.The difference between the means of PD and of the VAS pain over time (T0, T1, T3 and T6).

ObjectiveTo explore associations between remission, based on clinical and ultrasound definitions, and future good radiographic and physical outcome in early rheumatoid arthritis (RA).MethodsNewly diagnosed patients with RA followed a treat-to-target strategy incorporating ultrasound information in the Aiming for Remission in rheumatoid arthritis: a randomised trial examining the benefit of ultrasound in a Clinical TIght Control regimen (ARCTIC) trial. We defined 6-month remission according to Disease Activity Score, Disease Activity Score in 28 joints-erythrocyte sedimentation rate, American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) Boolean criteria, Simplified Disease Activity Index, Clinical Disease Activity Index and two ultrasound definitions (no power Doppler signal, grey scale score ≤2). Two outcomes were defined: no radiographic progression and good outcome (no radiographic progression+physical function≥general population median), both sustained 12–24 months. We calculated the ORs of these outcomes for the remission definitions.ResultsOf 103 patients, 42%–82% reached remission at 6 months, dependent on definition. Seventy-one per cent of patients had no radiographic progression and 37% had good outcome. An association between 6-month remission and no radiographic progression was observed for ACR/EULAR Boolean remission (44 joints, OR 3.2, 95% CI 1.2 to 8.4), ultrasound power Doppler (OR 3.6, 95% CI 1.3 to 10.0) and grey scale remission (OR 3.2, 95% CI 1.2 to 8.0). All clinical, but not ultrasound remission criteria were associated with achievement of a good outcome.ConclusionsOur data support ACR/EULAR Boolean remission based on 44 joints as the preferred treatment target in early RA. Absence of ultrasound inflammation was associated with no radiographic progression.Trial registration numberNCT01205854; Post-results.

Vitamin D Levels

Vitamin D deficiency is an important environmental risk factor that influences the prevalence and severity of several autoimmune diseases, including rheumatoid arthritis (RA). The aim of this study was to determine the incidence of vitamin D insufficiency and deficiency in patients with RA, to establish the relationship between serum vitamin D levels and indicators of disease activity. 156 patients with RA were included in the study, mean age 60.2 ± 13.9 years. Assessment of clinical status was performed, serum concentrations of rheumatoid factor (RF), C-reactive protein (CRP), total vitamin D (25(OH)D), antibodies to cyclic citrullinated peptide (ACCP) were determined. RA disease activity was evaluated using DAS28 (disease activity score), SDAI (Simplified Disease Activity Index) и CDAI (Clinical Disease Activity Index) scores. Average levels of 25(OH)D in the surveyed sample were 25.2 ± 13.2 ng/ml. The results of the study indicate a high prevalence of vitamin D deficiency in patients with RA. Normal indicators of vitamin D, its insufficiency and deficiency were observed in 47 (30.3 %), 45 (28.7 %) and 64 (40.7 %) patients, respectively. Low level of serum 25(OH)D was associated with higher indices of RA activity according to DAS28, SDAI and CDAI, as well as with greater tender joint count. Vitamin D should be prescribed as an adjunctive therapy in patients with active RA due to its potential immunomodulatory effect, as well as for the prevention and treatment of bone metabolism disorders.

Objective.To explore 5 possible criteria for remission in rheumatoid arthritis (RA) based on a patient self-report index, the Routine Assessment of Patient Index Data (RAPID3), with a careful joint examination and possible physician global estimate (DOCGL), but without a formal joint count or laboratory test.Methods.The ESPOIR early RA cohort of 813 French patients recruited in 2002–2005 was analyzed to identify patients in remission 6 months after enrollment, according to 2 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria: Boolean ≤ 1 for total tender joint count-28, swollen joint count-28, C-reactive protein, and patient global estimate (PATGL), and Simplified Disease Activity Index (SDAI) ≤ 3.3. Agreement with 7 other remission criteria was analyzed — Disease Activity Score-28 (DAS28) ≤ 2.6, Clinical Disease Activity Index (CDAI) ≤ 2.8, and 5 candidate criteria based on RAPID3, joint examination, and DOCGL: “RAPID3R” (RAPID3 ≤ 3.0); “RAPID3R+SJ1” (RAPID3 ≤ 3.0, ≤ 1 swollen joint); “RAPID3R+SJ1+D1” (RAPID3 ≤ 3.0, ≤ 1 swollen joint, DOCGL ≤ 1); “RAPID3R+SJ0” (RAPID3 ≤ 3.0, 0 swollen joints); and “RAPID3R+SJ0+D1” (RAPID3 ≤ 3.0, 0 swollen joints, DOCGL ≤ 1), according to kappa statistics, sensitivity, and specificity. Residual global, articular, and questionnaire abnormalities according to each criteria set were analyzed.Results.Among 813 ESPOIR patients, 720 had complete data to compare all 9 possible criteria. Substantial agreement with the Boolean criteria was seen for SDAI, CDAI, RAPID3R+SJ1, RAPID3R+SJ1+D1, RAPID3R+SJ0, and RAPID3R+SJ0+D1 (92.2%–94.7%, kappa 0.67–0.79), versus only moderate agreement for DAS28 or RAPID3R (79.9%–85.8%, kappa 0.46–0.55).Conclusion.Remission according to CDAI and RAPID3R+SJ1, but not DAS28 or RAPID3R, is similar to that of the ACR/EULAR criteria. RAPID3 scores require a complementary careful joint examination for clinical decisions, do not preclude formal joint counts or other indices, and may be useful in busy clinical settings.

Objective.Predictors of remission in rheumatoid arthritis (RA) have been defined in cross-sectional analyses using the 28-joint Disease Activity Score (DAS28), but not with newer composite disease activity measures or using the more clinically relevant state of sustained remission. We have evaluated predictors of remission using cross-sectional and longitudinal durations of disease state, and by applying additional definitions of remission [American College of Rheumatology/European League Against Rheumatism Boolean, Simplified Disease Activity Index (SDAI), and Clinical Disease Activity Index (CDAI)].Methods.Individuals in the Alberta Biologics Pharmacosurveillance Program were classified for the presence of remission (point and/or sustained > 1 yr) by each of the 4 definitions. Multivariate models were constructed including all available variables in the dataset and refined to optimize model fit and predictive ability to calculate OR for remission.Results.Nonsmoking status independently predicted point remission by all definitions (OR range 1.20–2.71). Minority ethnicity decreased odds of remission by DAS28 (OR 0.13) and CDAI (OR 0.09) definitions. Male sex was associated with DAS28 remission (OR 2.85), whereas higher baseline physician global (OR 0.67) and erythrocyte sedimentation rate values (OR 0.98) decreased odds of DAS28 remission. Higher baseline patient global score (OR 0.77) and swollen joint counts (OR 0.93) were negative predictors for CDAI remission. Higher baseline Health Assessment Questionnaire (OR 0.62) reduced odds for remission by the SDAI definition, and educational attainment increased these odds (OR 2.13). Sustained remission was negatively predicted by baseline physician global for the DAS28 (OR 0.80), and higher tender joint count (OR 0.96) for the CDAI.Conclusion.We demonstrate the influence of duration of remission state and remission definition on defining independent predictors for remission in RA requiring anti-tumor necrosis factor therapy. These predictors offer improved applicability for modern rheumatology practice.

Objectives:The Simplified Disease Activity Index (SDAI) 50 has good agreement with European League Against Rheumatism (EULAR) response measures for early Rheumatoid Arthritis (RA). There have been reports on early RA, but not on long-established RA. In this study, we analysed the relationships between various baseline factors and SDAI 50 after three months of treatment with biological disease-modifying antirheumatic drugs (bDMARDs) to determine the prognostic factors for long-established RA.Methods:Subjects were 260 RA patients who had been treated with bDMARDs for 3 months. The following characteristics were investigated: Patient backgrounds, the erythrocyte sedimentation rate (ESR), C-reactive protein and serum matrix metalloproteinase-3 levels, SDAI scores, and health assessment questionnaire disability index and short form-36 scores. As a primary outcome index, the SDAI response was defined as a 50% reduction in the SDAI score between baseline and 3 months (SDAI 50).Results:Baseline values of disease duration (odds ratio: 0.942, 95% CI: 0.902-0.984), smoking history (odds ratio: 2.272, 1.064-4.850), 28-tender joint count (odds ratio: 0.899, 0.827-0.977), evaluator's global assessment (odds ratio: 1.029, 1.012-1.047) and ESR (odds ratio: 1.015, 1.001-1.030) were determined to be significant factors based on logistic regression analysis.Conclusion:Our study demonstrated that RA patients with shorter disease duration, no smoking, and higher RA disease activity are more likely to achieve SDAI 50 through bDMARD treatment.

Abstract Background: Rheumatoid arthritis (RA) is chronic inflammatory arthritis with multi-joint involvement, especially small synovial joints in hands and feet. So far, the synovitis of which joint in hands or feet is better correlated with clinical disease activity indices is unknown; the correlation of synovitis detected by ultrasound in an individual joint with global disease activity is unclear either.Objectives: To explore the correlation between the ultrasound-detected synovitis in metacarpophalangeal (MCP), metatarsophalangeal (MTP), proximal interphalangeal (PIP) joints and the clinical disease activity indices in patients with RA.Methods: 30 joints, including bilateral MCP, PIP and MTP, were scanned for synovitis by ultrasound, semi-quantitatively scored for gray scale(GS) and power Doppler(PD). The correlation between Disease Activity Score-28 joints(DAS28), Simplified Disease Activity Index (SDAI), Clinical Disease Activity Index (CDAI) and ultrasound-detected synovitis score in each joint was assessed using Spearman’s rank correlation test. Results: 211 RA patients were included in this study. The whole GS scores of all MCP joints showed highest correlation with all clinical disease activity indices (r=0.403-0.452, p<0.01), followed by PIPs (r=0.318-0.331, p<0.01) and MTPs (r=0.277-0.301, p<0.01). Likewise, the whole PD scores of all MCP joints also showed highest correlation with the disease activity (r=0.332-0.396, p<0.01), followed by PIPs (r=0.211-0.242, p<0.01), and MTPs (r=0.198-0.222, p<0.01). The highest correlation of GS score with DAS28-ESR (r=0.411, p<0.01), DAS28-CRP (r=0.459, p<0.01), SDAI (r=0.444, p<0.01) was observed in MCP3 joint, while with CDAI (r=0.421, p<0.01) in MCP2 joint. The highest correlation of PD score with DAS28-ESR (r=0.353, p<0.01), DAS28-CRP (r=0.399, p<0.01), CDAI (r=0.368, p<0.01), SDAI (r=0.377, p<0.01) was in MCP5 joint. Conclusions: The ultrasound-detected synovitis at MCP joints, especially MCP2, MCP3, and MCP5 joints, was best correlated with composite disease activity of RA, in contrast to PIP and MTP joints. MCP joints should take greater weight in clinical disease activity assessment.

Abstract Background Musculoskeletal ultrasound (MSUS) and the multi-biomarker disease activity (MBDA) score are outcome measures that may aid in the management of rheumatoid arthritis (RA) patients. This study evaluated tofacitinib response by MSUS/MBDA scores and assessed whether baseline MSUS/MBDA scores or their early changes predict later clinical response. Methods Twenty-five RA patients treated with tofacitinib were assessed at baseline, 2, 6 and 12-weeks. Power doppler (PDUS) and gray scale (GSUS) ultrasound scores, MBDA score, clinical disease activity index (CDAI), and disease activity score (DAS28) were obtained. Pearson correlations and multiple linear regression models were used to evaluate associations and identify predictors of response to therapy. Results MSUS, MBDA scores, CDAI, and DAS28 improved significantly over 12 weeks (p < 0.0001). Baseline MSUS and MBDA score correlated with each other, and with 12-week changes in CDAI/DAS28 (r = 0.45–0.62, p < 0.05), except for GSUS with DAS28. Two-week change in MSUS correlated significantly with 12-week changes in CDAI/DAS28 (r = 0.42–0.57, p < 0.05), except for early change in PDUS with 12-week change in CDAI. Regression analysis demonstrated significant independent associations between baseline PDUS/MBDA score and 6-week change in CDAI/DAS28, with adjustment for baseline CDAI/DAS28 (all p < 0.05); and between baseline MBDA scores and 12-week change in DAS28 (p = 0.03). Conclusions RA patients treated with tofacitinib for 12 weeks demonstrated improvement by clinical, imaging, and biomarker end-points. Baseline PDUS and MBDA score were predictive of CDAI and DAS28 responses. This is the first study to evaluate early measurements of MSUS and MBDA score as predictors of clinical response in RA patients treated with tofacitinib.
