Artificial Intelligence Quantification of Enhanced Synovium Throughout the Entire Hand in Rheumatoid Arthritis on Dynamic Contrast-Enhanced MRI.

Challenges persist in achieving automatic and efficient inflammation quantification using dynamic contrast-enhanced (DCE) MRI in rheumatoid arthritis (RA) patients. To investigate an automatic artificial intelligence (AI) approach and an optimized dynamic MRI protocol for quantifying disease activity in RA in whole hands while excluding arterial pixels. Retrospective. Twelve RA patients underwent DCE-MRI with 27 phases for creating the AI model and tested on images with a variable number of phases from 35 RA patients. 3.0 T/DCE T1-weighted gradient echo sequence (mDixon, water image). The model was trained with various DCE-MRI time-intensity number of phases. Evaluations were conducted for similarity between AI segmentation and manual outlining in 51 ROIs with synovitis. The relationship between synovial volume via AI segmentation with rheumatoid arthritis magnetic resonance imaging scoring (RAMRIS) across whole hands was then evaluated. The reference standard was determined by an experienced musculoskeletal radiologist. Area under the curve (AUC) of receiver operating characteristic (ROC), Dice and Spearman's rank correlation coefficients, and interclass correlation coefficient (ICC). A P-value <0.05 was considered statistically significant. A minimum of 15 phases (acquisition time at least 2.5 minutes) was found to be necessary. AUC ranged from 0.941 ± 0.009 to 0.965 ± 0.009. The Dice score was 0.557-0.615. Spearman's correlation coefficients between the AI model and ground truth were 0.884-0.927 and 0.736-0.831, for joint ROIs and whole hands, respectively. The Spearman's correlation coefficient for the additional test set between the model trained with 15 phases and RAMRIS was 0.768. The AI-based classification model effectively identified synovitis pixels while excluding arteries. The optimal performance was achieved with at least 15 phases, providing a quantitative assessment of inflammatory activity in RA while minimizing acquisition time. 3 TECHNICAL EFFICACY: Stage 2.

Design of ANCHOR-RA: a multi-national cross-sectional study on screening for interstitial lung disease in patients with rheumatoid arthritis

BackgroundPatients with rheumatoid arthritis (RA) are at risk of developing interstitial lung disease (ILD), which is associated with high mortality. Screening tools based on risk factors are needed to decide which patients with RA should be screened for ILD using high-resolution computed tomography (HRCT). The ANCHOR-RA study is a multi-national cross-sectional study that will develop a multivariable model for prediction of RA-ILD, which can be used to inform screening for RA-ILD in clinical practice.MethodsInvestigators will enrol consecutive patients with RA who have ≥ 2 of the following risk factors for RA-ILD: male; current or previous smoker; age ≥ 60 years at RA diagnosis; high-positive rheumatoid factor and/or anti-cyclic citrullinated peptide (titre > 3 x upper limit of normal); presence or history of certain extra-articular manifestations of RA (vasculitis, Felty’s syndrome, secondary Sjögren’s syndrome, cutaneous rheumatoid nodules, serositis, and/or scleritis/uveitis); high RA disease activity in the prior 12 months. Patients previously identified as having ILD, or who have had a CT scan in the prior 2 years, will not be eligible. Participants will undergo an HRCT scan at their local site, which will be assessed centrally by two expert radiologists. Data will be collected prospectively on demographic and RA-related characteristics, patient-reported outcomes, comorbidities and pulmonary function. The primary outcomes will be the development of a probability score for RA-ILD, based on a multivariable model incorporating potential risk factors commonly assessed in clinical practice, and an estimate of the prevalence of RA-ILD in the study population. It is planned that 1200 participants will be enrolled at approximately 30 sites in the USA, UK, Germany, France, Italy, Spain.DiscussionData from the ANCHOR-RA study will add to the body of evidence to support recommendations for screening for RA-ILD to improve detection of this important complication of RA and enable early intervention.Trial registrationclinicaltrials.gov NCT05855109 (submission date: 3 May 2023).

Perinatal Use and Discontinuation of Disease-Modifying Antirheumatic Drugs: Outcomes of Patients Seen at a Pregnancy and Rheumatic Diseases Clinic.

Managing rheumatic disease activity using pregnancy-compatible medications is essential for reducing adverse maternal and fetal outcomes. We characterized medication use and discontinuation before, during, and after pregnancy, among female patients with rheumatic diseases attending a targeted pregnancy and rheumatic diseases clinic. We conducted a cross-sectional medical record review of female patients with rheumatic diseases at a Canadian clinic between January 2017 and July 2020. Patients were categorized by pregnancy stage at their latest clinic visit: (1) preconception; (2) pregnant; (3) postpartum. We assessed use of conventional, biologic, and targeted synthetic disease-modifying antirheumatic drugs (DMARDs), prednisone, and nonsteroidal anti-inflammatory drugs across 6 perinatal windows: 24 and 12 months preconception, each pregnancy trimester, and 3 months postpartum. We reported adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for medication discontinuation in the first trimester and subsequent disease flare. Of 230 included patients, 85 (37.0%), 12 (5.2%), and 133 (57.8%) were preconception, pregnant, and postpartum, respectively. Approximately half experienced at least 1 disease flare during each pregnancy stage (56.4% preconception, 58.1% during pregnancy, and 53.7% postpartum). Most used at least 1 DMARD throughout the perinatal period (82.6% preconception, 55.6% during pregnancy, and 45.1% postpartum). Overall, 25.5% discontinued at least 1 DMARD in the first trimester. DMARD discontinuation was associated with disease flare during pregnancy (aOR, 1.49; 95% CI, 0.55-4.03; p = 0.87) and postpartum (aOR, 3.09; 95% CI, 0.83-11.47; p = 0.09). Patients receiving care at a pregnancy and rheumatic disease clinic show perinatal medication use patterns consistent with recent recommendations and clinical guidelines.

Evaluating factors associated with telehealth appropriateness in outpatient rheumatoid arthritis encounters using the Encounter Appropriateness Score for You (EASY).

Telehealth has been proposed as a safe and effective alternative to in-person care for rheumatoid arthritis (RA). The purpose of this study was to evaluate factors associated with telehealth appropriateness in outpatient RA encounters. A prospective cohort study (1/1/21-8/31/21) was conducted using electronic health record data from outpatient RA encounters in a single academic rheumatology practice. Rheumatology providers rated the telehealth appropriateness of their own encounters using the Encounter Appropriateness Score for You (EASY) immediately following each encounter. Robust Poisson regression with Generalized Estimating Equations (GEE) modeling was used to evaluate the association of telehealth appropriateness with patient demographics, RA clinical characteristics, comorbid non-inflammatory causes of joint pain, previous and current encounter characteristics, and provider characteristics. During the study period, 1,823 outpatient encounters with 1,177 unique RA patients received an EASY score from 25 rheumatology providers. In the final multivariate model [Relative Risk (95% Confidence Interval)], factors associated with increased telehealth appropriateness included higher average provider preference for telehealth in prior encounters [1.26 (1.21-1.31)], telehealth as the current encounter modality [2.27 (1.95-2.64)], and increased patient age [1.05 (1.01-1.09)]. Factors associated with decreased telehealth appropriateness included moderate [0.81 (0.68-0.96)] and high [0.57 (0.46-0.70)] RA disease activity and if the previous encounter were conducted via telehealth [0.83 (0.73-0.95)]. In this study, telehealth appropriateness was most associated with provider preference, the current and previous encounter modality, and RA disease activity. Other factors like patient demographics, RA medications, and comorbid non-inflammatory causes of joint pain were not associated with telehealth appropriateness.

Active Rheumatoid Arthritis and Scoliosis: A Mid-Term Cohort Study.

Retrospective cohort study. To elucidate the factors related to progression of scoliosis in patients with rheumatoid arthritis (RA) using longitudinal cohort data. Thirty percent of patients with RA have lumbar scoliosis. However, the effectiveness of current treatment methods in preventing the progression of scoliosis is not well-understood due to a lack of longitudinal studies. We enrolled 180 patients with RA who were followed up for over two years, all of whom underwent standing spinal X-rays. These patients were categorized based on their disease activity score-28 with erythrocyte sedimentation rate (DAS28-ESR) into two groups: those in remission (n=76) and those in non-remission (n=104). We evaluated various radiographic measures, including C7 center sacral vertical line (C7-CSVL), pelvic obliquity, major Cobb angle, and curve location. Fifty-three (29.4%) patients presented progression of scoliosis during a mean follow-up period of 4.8 years. Patients in the non-remission showed larger Cobb angle at baseline and final follow-up, compared to those in remission. The annual progression rate of the curve was also greater in the non-remission group (1.04 degree /year), than in the remission group (0.59 degree /year, P=0.001). There was no difference in the incidence of new vertebral fractures. The presence of a baseline cobb angle of 10 degree or more (OR: 3.14; 95% CI: 1.38-7.13; P=0.006), glucocorticoid use (OR: 2.88; 95% CI: 1.18-7.06; P=0.021), and non-remission at baseline (OR: 2.83; 95% CI: 1.25-6.41; P=0.012) were significant risk factors for progression of scoliosis. RA disease activity is linked to progression of scoliosis in patients with RA. Patients with RA who present with an initial scoliosis of 10 degrees or greater, require glucocorticoids for treatment and are in non-remission at baseline may be at high risk for scoliosis progression.

Rheumatoid arthritis disease activity significantly impacts on the severity of interstitial lung disease

ObjectivesRheumatoid arthritis (RA) related interstitial lung disease (ILD) impacts on the treatment strategy and its prognosis in patients with RA. However, the relationship between RA disease activity and the severity of comorbid ILD has not been fully investigated. This study aimed to investigate the impact of RA disease activity on the severity of comorbid ILD in detail based on currently established visual scoring method along with physiological severity.MethodsConsecutive patients with RA visiting to our Rheumatology Centre between December 2020 and December 2023 were analysed. The radiological severity of ILD was evaluated by averaging the extent of the combined lesion of ground glass opacity, reticulation and honeycombing in 5% increments in six representative high-resolution computed tomography slices ranging from 0% (no involvement) to 100% (all lung fields affected) according to Goh and Walsh’s method. Associations between the radiological and physiological severity of ILD and patients’ features were investigated using linear regression analysis.ResultsAmong 124 patients (32 men, 92 women), the median age was 70 years, and the median disease duration was 2.92 years. Radiological severity of ILD was 0% (without ILD) in 107 (86.2%), ILD with extent < 10% in nine (7.2%), ILD with extent ≥10% and < 20% in three (2.4%), ILD with extent ≥20% in five (4.0%). Both disease activity score (DAS)28-erythrocyte sedimentation rate (ESR) (standardized coefficient = 0.199, P = 0.03) and rheumatoid factor titre (standardized coefficient = 0.247, P = 0.01) were significantly associated with the radiological quantitative severity of ILD in multivariate analysis adjusted for age, sex, disease duration, smoking status and anti-citrullinated peptide antibody titre. DAS28-ESR was significantly associated with forced vital capacity% predicted (standardized coefficient = -0.230, P = 0.047).ConclusionsDisease activity of RA was significantly associated with the severity of RA-ILD both radiologically and physiologically.

Multimodal PA/US imaging in Rheumatoid Arthritis: Enhanced correlation with clinical scores

BackgroundAccurate assessment of Rheumatoid Arthritis (RA) activity remains a challenge. Multimodal photoacoustic/ultrasound (PA/US) joint imaging emerges as a novel imaging modality capable of depicting microvascularization and oxygenation levels in inflamed joints associated with RA. However, the scarcity of large-scale studies limits the exploration of correlating joint oxygenation status with disease activity. ObjectiveThis study aimed to explore the correlation between multimodal PA/US imaging scores and RA disease activity, assessing its clinical applicability in managing RA. MethodsIn this study, we recruited 111 patients diagnosed with RA and conducted examinations of seven small joints on their clinically dominant side using a PA/US imaging system. The PA and power Doppler ultrasound (PDUS) signals were semi-quantitatively assessed using a 0–3 grading system. The cumulative scores for PA and PDUS across these seven joints (PA-sum and PDUS-sum) were calculated. Relative oxygen saturation (So2) values of inflamed joints on the clinically dominant side were measured, and categorized into four distinct PA+So2 patterns. The correlation between PA/US imaging scores and disease activity indices was systematically evaluated. ResultsAnalysis of 777 small joints in 111 patients revealed that the PA-sum scores exhibited a strong positive correlation with standard clinical scores for RA, including DAS28 [ESR] (ρ = 0.682), DAS28 [CRP] (ρ = 0.683), CDAI (ρ = 0.738), and SDAI (ρ = 0.739), all with p < 0.001. These correlations were superior to those of the PDUS-sum scores (DAS28 [ESR] ρ = 0.559, DAS28 [CRP] ρ = 0.555, CDAI ρ = 0.575, SDAI ρ = 0.581, p < 0.001). Significantly, in patients with higher PA-sum scores, notable differences were observed in the erythrocyte sedimentation rate (ESR) (p < 0.01) and swollen joint count 28 (SJC28) (p < 0.01) between hypoxia and intermediate groups. Notably, RA patients in the hypoxia group exhibited higher clinical scores in certain clinical indices. ConclusionMulti-modal PA/US imaging introduces potential advancements in RA assessment, especially regarding So2 evaluations in synovial tissues and associated PA scores. However, further studies are warranted, particularly with more substantial sample sizes and in multi-center settings. SummaryThis study utilized multi-modal PA/US imaging to analyze Rheumatoid Arthritis (RA) patients' synovial tissues and affected joints. When juxtaposed with traditional PDUS imaging, the PA approach demonstrated enhanced sensitivity, especially concerning detecting small vessels in thickened synovium and inflamed tendon sheaths. Furthermore, correlations between the derived PA scores, PA+So2 patterns, and standard clinical RA scores were observed. These findings suggest that multi-modal PA/US imaging could be a valuable tool in the comprehensive assessment of RA, offering insights not only into disease activity but also into the oxygenation status of synovial tissues. However, as promising as these results are, further investigations, especially in larger and diverse patient populations, are imperative. Key points⸸ Multi-modal PA/US Imaging in RA: This novel technique was used to assess the So2 values in synovial tissues and determine PA scores of affected RA joints.⸸ Correlation significantly with Clinical RA Scores: Correlations significantly were noted between PA scores, PA+So2 patterns, and standard clinical RA metrics, hinting at the potential clinical applicability of the technique.

Relationship between Triglyceride-Glucose Index and Disease Activity and Subclinical Atherosclerosis in Rheumatoid Arthritis.

In rheumatoid arthritis (RA), insulin resistance (IR) is related to inflammatory markers, disease activity, and progression of atherosclerotic changes. Triglyceride-glucose (TyG) index is a relatively new indicator of IR. The present study aimed to investigate the relationship between TyG index, disease activity and subclinical atherosclerosis (SCA) in RA patients. The present case-control study included 100 RA patients and 50 age- and sex-matched healthy controls. All participants were subjected to careful history taking through clinical examination and standard laboratory assessment. The TyG index was calculated as TyG index = ln (Fasting triglyceride (mg/dL) × fasting glucose (mg/dL))/2. Carotid intima-media thickness (CIMT) measurement was done using B-mode ultrasound. Patients had significantly higher TyG index as compared to controls. Patients with high disease activity had significantly higher frequency of extraarticular manifestations (39.6% versus 51.6%, p = 0.028), higher Larsen score (3.8 ± 1.3 versus 2.8 ± 1.2, p < 0.001), higher anti-cyclic citrullinated peptide (anti-CCP) levels (median (IQR): 243.1 (205.0-408.0) U/ml versus 99.0 (78.0-332.5), p < 0.001), higher TyG index (4.8 ± 0.22 versus 4.67 ± 0.24, p = 0.006), and higher CIMT (0.87 ± 0.22 versus 0.77 ± 0.17 mm, p = 0.018). Patients with SCA had higher BMI (34.6 ± 6.2 versus 30.5 ± 5.3 Kg/m2, p < 0.001), higher Larsen score (3.7 ± 1.4 versus 3.1 ± 1.3, p = 0.028) and higher TyG index (4.89 ± 0.23 versus 4.64 ± 0.19, p < 0.001). Binary logistic regression analysis identified patients' age (OR (95% CI): 0.94 (0.89-0.99), p = 0.018), Larsen score (OR (95% CI): 1.93 (1.32-2.82), p = <0.001), anti-CCP (OR (95%): 1.04 (1.02-1.07), p = 0.032), and TyG index (OR (95% CI): 22.67 (2.14-240.4), p = 0.01) as significant predictors of high disease activity in multivariate analysis. IR estimated by the TyG index is related to disease activity and SCA in RA patients.

A study of carotid intima media thickness in patients with rheumatoid arthritis and its correlation with acute phase reactants and disease activity

Introduction: There is increased risk of cardiovascular morbidity and mortality in patients of rheumatoid arthritis (RA) due to accelerated atherosclerosis. In this study we measured Carotid artery intima media thickness (CIMT) as a surrogate marker for subclinical atherosclerosis in RA patients without pre-existing cardiovascular disease. This study also analyzed the correlation between CIMT, disease duration, Simplified Disease Activity Index (SDAI) and acute phase reactants. Methods: A cross-sectional study was conducted on 90 patients divided into two groups of 45 patients of RA and another 45 control subjects. Subjects with RA and age and sex matched healthy controls were included in the study without pre-existing CV risk factors. Complete clinical evaluation, hematological and biochemical profile done. ESR, CRP and platelet count were used as markers of acute phase reactants. All the RA patients included in the study were evaluated for their disease activity using Simplified Disease Activity Index (SDAI). All the subjects including the controls evaluated for carotid intima media thickness by using carotid ultrasonography. CIMT measured in common carotid artery bilaterally by examining throughout common carotid artery up to 2 cm proximal to bifurcation. CIMT measurement taken at the site of greatest thickness. All measurements taken in diastole, measured in phase when lumen diameter is at its smallest and IMT at its largest. Mean value of 6 readings (3 from each side) taken as final CIMT for evaluation. B mode (linear probe) USG was used to determine carotid IMT. Results: 45 cases and similar control subjects included in the study with mean age (SD) as 45.07 (14.81) years. We found female preponderance with 37 females out of 45 cases. Mean (SD) disease duration in male subjects was 5.38(2.40) years while in females was 5.09 (2.78) years. CRP was found to be significantly increased in cases group with mean (SD) of 5.75(8.85) mg/dl. ESR significantly raised to 35.22(13.55) mm/hour in cases group compared to control group where it was 16.16(5.71) mm/hr. Mean (SD) platelets (x10³/mm³) were 229.24(69.80) in cases while controls had 290.33(83.85), so platelets correlation with disease could not be established. CIMT was significantly raised in cases group. Mean (SD) CIMT in cases was 0.95(1.06) mm whereas in control group it was 0.60(0.16) mm with p value of 0.002. Moderate positive correlation was found between CIMT (mm) and SDAI and this correlation was statistically significant with p=0.001. For every 1 unit increase in CIMT, the SDAI increases by 2.92 units. A strong positive correlation between CIMT (mm) and Disease Duration (Years), and this correlation was statistically significant (rho = 0.9, p = &lt;0.001). For every 1 unit increase in CIMT (mm), the Disease Duration (Years) increases by 1.26 units. Conversely, for every 1 unit increase in Disease Duration (Years), the CIMT (mm) increases by 0.19 units. Conclusion: A strong correlation was observed between CIMT and disease duration in rheumatoid arthritis. Hence, CIMT can be a useful surrogate marker for detecting atherosclerosis in patients with RA. In view of the relation to duration of disease, established RA patients should regularly be screened to identify the evidence of atherosclerosis and manage it earlier. Prevention of cardiovascular disease in RA requires an integrated approach encompassing cardiovascular risk factors screening and management, effective and sustained control of RA disease activity, high index of suspicion and prompt investigation of suspected cardiac disease.

Inflammatory profile in patients with rheumatoid arthritis and sarcopenia.

Sarcopenia is characterized by the loss of muscle mass and strength associated with aging; however, individuals with chronic diseases are at risk at the early stages. In rheumatoid arthritis (RA), sustained chronic inflammation influences muscle deterioration. It may expedite the development of sarcopenia, which has been linked to physical disability, cardiovascular events, disease activity of RA, and premature death. We aimed to compare the inflammatory profiles of patients with RA with and without sarcopenia. This cross-sectional study involved 165 women with RA. Sarcopenia was diagnosed according to criteria established by the European Working Group on Sarcopenia in Older People. To assess the inflammatory profile, concentrations of cytokines such as EGF, IL-17, IL-1α, IL-1β, IL-6, TNFα, TNFβ, and creatine kinase (CK) were measured. The prevalence of sarcopenia was 15.8% (95% CI: 8.9-18.2). The median age of patients with sarcopenia was 59.5years (49.8-65.3), compared to 50years (43-59years) p = 0.001. The disease duration was also longer in patients with sarcopenia, 21years (15-30), compared to those without sarcopenia, 13years (7.3-20) p = 0.001. The inflammatory profile differed between patients with and without sarcopenia, revealing that the cytokines IL-1α, IL-6, and TNFβ concentrations were significantly higher (p < 0.05) in patients with sarcopenia, adjusted for BMI, age, and disease duration. Patients with RA and sarcopenia were older and exhibited longer disease duration and higher levels of inflammatory cytokines compared to those without sarcopenia. These findings suggest potential implications for clinical outcomes. Key Points • The prevalence of sarcopenia in women with rheumatoid arthritis was 15.8% (95% CI, 8.9-18.2). • Levels of IL-1α, IL-6, and TNFβ cytokines were significantly higher in women with rheumatoid arthritis and sarcopenia compared with those without sarcopenia, adjusted for BMI, age, and disease duration.

P114 Promoting physical activity using mobile health technology in people living with Rheumatoid Arthritis: MOTIVATE RA

Abstract Background/Aims People living with rheumatoid arthritis (RA) tend to be less active than the general population which may be due to RA associated musculoskeletal pain, stiffness and fatigue. The health benefits of physical activity (PA) are widely recognised in the general population and studies in RA have also highlighted improvement in RA associated symptoms. However, encouraging increased PA in people living with RA is challenging and adherence to PA is usually low. Mobile health (mHealth) technology (i.e., fitness watches and apps) may provide an effective and economical solution to promoting PA in this high-risk population. The aims of the current study were to assess whether use of mHealth technology in RA i) increases PA levels and ii) reduces RA disease activity. Methods People with RA were randomised to either the MOTIVATE (mHealth intervention) or conventional care (CC) groups. The CC group were provided with online educational materials, as provided in routine care (e.g., PA information leaflets), to increase PA whereas the MOTIVATE group were provided with a personalised, progressive walking programme delivered via mHealth technology with ongoing, individualised support throughout the 12-week intervention. All participants received a self-testing kit, via mail, at baseline (week 0) and post-intervention (12 weeks). Measures included anthropometrics, blood pressure, PA monitoring, health questionnaires and all were requested to self-report RA disease activity using RADAI-5. Change data between weeks 0 and 12 were compared between groups using One-Way ANCOVA, controlling for baseline, and reported as mean difference (95% CI). Results Of 50 participants, 25 were randomised to the MOTIVATE group (age 50±11years; BMI 29±7kg/m2; females n=23), and 25 to CC (n=25, age 50±11years; BMI 26±6 kg/m2; females n=24). An increase in moderate-to-vigorous PA was observed in the MOTIVATE group, compared to a decrease in CC [81min (1, 160) vs. -35min (-123, 53); P=0.09)]. This was accompanied by an increase in steps per day in the MOTIVATE group, and a decrease in CC [763 (-432, 1957) vs. -76 (-1267, 1115); P=0.40]. A reduction in PHQ-9 depression score was evident in the MOTIVATE group whilst CC were unchanged [-2 (-2, -3) vs. 0 (-2, 0); P=0.07]. RADAI-5 decreased in the MOTIVATE group and stayed the same in CC [-2 (-2, 0) vs. 0(-2, 0), P=0.27]. Conclusion These findings identify the potential effectiveness of an mHealth PA programme to increase PA levels in people living with RA. Use of remote PA monitoring, with support from exercise specialists, may be an effective strategy to improve engagement in exercise and PA in the RA population. Data is suggestive this could improve RA related symptoms, although we did not observe statistical significance. Disclosure D.J.

OA20 Serious infections hospital admissions and mortality in patients with early inflammatory arthritis: results from the National Early Inflammatory Arthritis Audit

Abstract Background/Aims To identify the risk of serious infections (SI) according to initial treatment strategy, using conventional synthetic disease modifying anti-rheumatic drugs (csDMARD) and corticosteroids, in patients recruited to the National Early Inflammatory Arthritis Audit (NEIAA). Methods An observational cohort study design was used. The population included adults in England with a new onset rheumatoid arthritis (RA), fulfilling ACR/EULAR 2010 criteria, between April 2018-March 2021. Outcomes studied were SI, defined by infections requiring hospitalisation (primary admission diagnosis/nosocomial acquisition) or death (SI stated on death certificate), identified using NHS Digital linkage. Patients' characteristics were tabulated by treatment strategies. Hazard ratios (HR) were calculated using single failure Cox proportional-hazards models, with confounders-adjusted models (age, gender, smoking status, comorbidities, social deprivation) and fully-adjusted models including disease factors (seropositivity, DAS28). Individuals were considered at risk from the date of RA diagnosis, and censored at SI event, death, or March 2021 (whichever was earliest). Results 20,060 patients with RA were included. Initial DMARD therapy was known for 19,572 patients, of whom 11,966 were on methotrexate/MTX based strategies (mono or combo), 5,059 on csDMARD combination strategies (other than MTX) and 2,547 on no DMARD strategy. 15,319 patients were on corticosteroids at baseline. Mean age 59.5 years (+/-15); 63% female; smoking status (20% current; 30% ex-smokers); comorbidities (21% hypertension; 10% diabetes; and 12% lung disease). Rheumatoid Factor/CCP antibodies were positive in 68%. At presentation, median disease scores were 5.1 (interquartile range [IQR]: 4.0-5.9) for DAS28, 1.1 (IQR: 0.6-1.7) for health assessment questionnaire (HAQ) and 24 (IQR: 16.0-33.0) for musculoskeletal health questionnaire (MSKHQ).There were 519 SI admissions and 17 SI deaths, corresponding to incidence rates per 100 person-years for admissions: 3.19 (95% CI: 2.93-3.48) and deaths: 0.10 (95% CI: 0.06-0.16). In fully-adjusted models, increasing age predicted both SI admissions and deaths. Being a smoker, having a comorbidity, higher disease activity (DAS28), symptom burden (MSKHQ) and disability (HAQ) at presentation associated with more SI admissions. For each 1 unit increase in DAS28, the risk of SI increased by 8% (HR 1.08 [95% CI:1.01-1.16]). Seropositivity did not associate with SI. MTX-based strategies 0.75 (95% CI:0.62-0.91) and csDMARD combination therapy 0.70 (95% CI:0.53-0.94) associated with fewer SI admissions compared to no DMARD. In unadjusted models, corticosteroid associated with more SI admissions 1.29 (95% CI:1.10 -1.62); however, in fully-adjusted models this association was no longer statistically significant. csDMARD strategies did not associated with SI deaths in any of the models. Conclusion Patient and disease factors at diagnosis appear to be important predictors of admissions and mortality for serious infections. Infection risk appears to be greatest in those with higher RA disease activity. An important limitation is that NEIAA does not capture data on treatment changes over time and steroid use beyond baseline. Disclosure M. Adas: None. K. Bechman: None. M.

Association of the multi-biomarker disease activity score with arterial 18-fluorodeoxyglucose uptake in rheumatoid arthritis.

Rheumatoid arthritis (RA) and atherosclerosis share many common inflammatory pathways. We studied whether a multi-biomarker panel for RA disease activity (MBDA) would associate with changes in arterial inflammation in an interventional trial. In the TARGET Trial, RA patients with active disease despite methotrexate were randomly assigned to the addition of either a TNF inhibitor or sulfasalazine+hydroxychloroquine (triple therapy). Baseline and 24-week follow-up 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography scans were assessed for change in arterial inflammation measured as the maximal arterial target-to-blood background ratio of FDG uptake in the most diseased segment of the carotid arteries or aorta (MDS-TBRmax). The MBDA test, measured at baseline and weeks 6, 18, and 24, was assessed for its association with the change in MDS-TBRmax. Interpretable scans were available at baseline and week 24 for n = 112 patients. The MBDA score at week 24 was significantly correlated with the change in MDR-TBRmax (Spearman's rho = 0.239; p= 0.011) and remained significantly associated after adjustment for relevant confounders. Those with low MBDA at week 24 had a statistically significant adjusted reduction in arterial inflammation of 0.35 units vs no significant reduction in those who did not achieve low MBDA. Neither DAS28-CRP nor CRP predicted change in arterial inflammation. The MBDA component with the strongest association with change in arterial inflammation was serum amyloid A (SAA). Among treated RA patients, achieved MBDA predicts of changes in arterial inflammation. Achieving low MBDA at 24 weeks was associated with clinically meaningful reductions in arterial inflammation, regardless of treatment.

Ultrasonographic Evaluation of the Ankle Joint in Relation to Rheumatoid Factor Status and Disease Activity in Patients with Rheumatoid Arthritis

Abstract Background: Rheumatoid arthritis (RA) is a form of inflammatory disease whose clinical pattern is largely dependent on the presence of both anti-citrullinated protein antibodies and rheumatoid factor (RF). Although this is still debatable, seronegative RA seems to be a somewhat less serious condition. The present study aimed to evaluate ankle joint ultrasound in relation to RF status and disease activity in RA patients. Methods: A cross-sectional study involving RA patients from a single center was conducted. Laboratory test evaluations and clinical activity assessments were carried out. The ankle joint was examined using musculoskeletal ultrasound (US). Results: The study included 100 patients with established RA in total. Eighty-two patients tested positive for RF with a mean age of 42.3, whereas only 18 tested negative with a mean age of 39.6. Patients who tested positive for RF had a longer duration of illness (9.39 ± 5.39 vs. 4.56 ± 3.24). There were no differences in clinical activity scores between the seropositive and seronegative groups. The pathological US findings of any ankle joint showed no differences between the seropositive and seronegative groups. Patients with US findings of tibialis posterior tenosynovitis in the left ankle and synovitis and erosion in the right ankle, particularly in the tibiotalar and talonavicular joints, had significantly high Disease Activity Score 28-Erythrocyte sedimentation rate-scores. The increased disease activity was accompanied by significant erosions on both ankles. Conclusion: In terms of disease activity, there is no clinically significant difference between seropositive and seronegative RA patients. Sonographic ankle joint abnormalities do not appear to be associated with the patients’ RF status. High RA disease activity, on the other hand, is associated with synovitis and erosions, particularly in the talonavicular and tibiotalar joints, as well as tibialis posterior tenosynovitis.

CCR9+CD4+ T cells are associated with disease activity in patients with rheumatoid arthritis.

An increase in CD4+ T cells in the synovium is closely linked to the pathogenesis of rheumatoid arthritis (RA). We aimed to identify the possible causes of the elevated CD4+ T cell levels and to explore the factors influencing disease activity in RA. Fifty-five RA patients, including 28 with active RA (ARA), 27 with inactive RA, and 22 healthy controls, were recruited for this study. The proportion of CCR9+CD4+ T cells and the expression of chemokine receptor 9 (CCR9) on CD4+ T cells were analyzed by flow cytometry. Enzyme-linked immunosorbent assay and chemiluminescent immunoassay were used to evaluate interleukin (IL)-17A and IL-6 levels, respectively. The proportion of CCR9+CD4+ T cells and the expression of CCR9 on CD4+ T cells increased significantly in peripheral blood (PB) and synovial fluid (SF) in ARA compared to those in inactive RA. Furthermore, SF contained more CCR9+CD4+ T cells, IL-6, and IL-17A than PB in RA patients. Moreover, CD4+ T cells in the PB of patients with RA, especially ARA, expressed more CCR9 and secreted more IL-6 and IL-17A after activation. Here, we also demonstrated that both the percentage of CCR9+ cells in CD4+ T cells and the expression of CCR9 on circulating CD4+ T cells were positively correlated with erythrocyte sedimentation rate, hypersensitive C-reactive protein, rheumatoid factor, and anti-cyclic citrullinated peptide antibody. CCR9+CD4+ T cells are elevated in PB and SF, and are associated with disease activity in patients with RA.

Are There Sex-Related Differences in the Effectiveness of Janus Kinase Inhibitors in Rheumatoid Arthritis Patients?

Background: There is evidence suggesting the existence of sex differences in the effectiveness of specific drug classes for rheumatoid arthritis (RA). Our study stands as the first to elucidate sex-related differences in the effectiveness of Janus kinase (JAK) inhibitors. Methods: The study involved 150 RA patients treated with tofacitinib, baricitinib, upadacitinib, or filgotinib between September 2017 and October 2023. Sex differences in achieving remission and low disease activity (LDA) were identified through logistic regression analyses. Sex disparities in treatment effectiveness survival were evaluated through the Kaplan-Meier estimate, employing the log-rank test for comparison. The Cox model was applied to analyze the variable sex as a potential factor that could influence the maintenance of the JAK inhibitor treatment effectiveness. Results: Concerning the achievement of remission and LDA, no differences were observed between sexes in terms of the 28-joint Disease Activity Score (DAS28) C-reactive protein (CRP), the Clinical Disease Activity Index (CDAI), and the Simplified Disease Activity Index (SDAI). With respect to the DAS28-erythrocyte sedimentation rate (ESR), female patients, compared to males, possessed 70% lower odds of achieving remission (p = 0.018) and 66% lower odds of achieving LDA (p = 0.023). No differences were observed in treatment effectiveness survival between sexes (p = 0.703). Sex was not found to influence the survival of JAK inhibitor treatment effectiveness (p = 0.704). Conclusions: Being a female or male patient does not entail differences in the effectiveness of the JAK inhibitor treatment. Our findings encourage the consideration of a global pool of composite indices (DAS28-ESR/CRP, CDAI, SDAI) to measure RA disease activity, thus individualizing the target value as advocated by the treat-to-target strategy.

Intradermal acupuncture in the treatment of rheumatoid arthritis with liver and kidney deficiency syndrome – A sham-controlled, randomized, clinical trial

Background and purposeRheumatoid arthritis (RA) is called “immortal cancer”, and it affects the quality of life, disability rate and even the survival of patients. This study aimed to observe the clinical efficacy, and adverse reactions of intradermal acupuncture (IA) in the treatment of RA patients with liver and kidney deficiency syndrome. Materials and methods132 RA patients were split into an IA group and a sham IA group at a 1:1 ratio. Both groups were assessed before and after the intervention with the assessments: a traditional Chinese medicine (TCM) syndrome evaluation, the Health Assessment Questionnaire (HAQ), the Disease Activity Score 28 (DAS28) and serum C-reactive protein (CRP). ResultsThere was a statistically significant difference in TCM syndrome evaluation, HAQ, DAS28, and CRP between both groups before and after treatment (P < 0.01). The improvement of TCM syndrome evaluation (95% CI [1.14(0.38–1.89)]; P = 0.001), HAQ (95% CI [2.00(1.00–3.00)]; P = 0.003), and DAS28 (95% CI [0.11(0.02–0.20)]; P = 0.021) in the IA group was more obvious than that in the sham IA group (P < 0.05), except for CRP (95% CI [0.50(− 2.09 to 7.08)], P = 0.786). The difference in CRP outcome changes between the two groups was not statistically significant (P > 0.05). Both groups had comparable results in the implementation of RA in the upper and lower extremity acupoints and did not differ due to different sites (IA group: P = 0.852; sham IA group: P = 0.861). The comparison of effective rate of the upper limb as well as that of the lower limb was statistically significant (P = 0.001). Besides, patients reported no adverse effects. ConclusionThe IA intervention was associated with a promising effect on the decrease in RA disease activity and delayed overall disease progression.

Pregnancy and the Autoimmune Patient.

This article will review the current understanding of the immunologic changes that occur during pregnancy. It will discuss the impact of pregnancy on the disease activity of autoimmune or inflammatory rheumatic diseases (AIRD). Lastly, it will highlight the most recent data on pre-conception and pregnancy management practices that can improve pregnancy outcomes in autoimmune patients. Pregnancy is an immunologically complex and dynamic state that may affect the activity of AIRDs, with more patients having active disease during pregnancy than previously thought. Uncontrolled inflammatory diseases are associated with poor pregnancy outcomes such as preeclampsia, small for gestational age infants, and prematurity. Pre-conception counseling and early pregnancy planning discussions can help ensure optimal disease control and medication management prior to attempting conception. Adequate control of AIRDs on pregnancy-compatible medications during the pre-conception, pregnancy, and postpartum periods is required for optimal pregnancy outcomes.
