RESUMEN
OBJECTIVE: To assess organ damage, with emphasis on the cardiovascular system, over the different stages of the disease in a large SLE cohort. METHODS: Multicentre, longitudinal study of a cohort of 4219 patients with SLE enrolled in the Spanish Society of Rheumatology Lupus Registry. Organ damage was ascertained using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI). We longitudinally analysed SDI (globally and for each domain) over time only in the 1274 patients whose dates of damage events had been recorded. RESULTS: During the first year after diagnosis of SLE, 20% of the 1274 patients presented with new damage manifestations. At years 2 and 3, new damage was recorded in 11% and 9% of patients. The annual percentage of patients with new damage after year 5 decreased to 5%. In the first year with the disease, most damage was accumulated in the musculoskeletal, neuropsychiatric and renal systems; in later stages, most damage was in the musculoskeletal, ocular and cardiovascular systems. Considering 'cerebrovascular accident' and 'claudication for 6 months' as cardiovascular items, the cardiovascular system was the second most affected system during the early stages of SLE, with 19% of the patients who presented with damage affected at first year after diagnosis. During the late stages, 20-25% of the patients presenting with new damage did so in this modified cardiovascular domain of the SDI. CONCLUSIONS: New damage occurs mainly during the first year following diagnosis of SLE. Cardiovascular damage is relevant in both the early and the late stages of the disease. Strategies to prevent cardiovascular damage should be implemented early after diagnosis of SLE.

BACKGROUND: Hydroxychloroquine (HCQ) is the first-line treatment for systemic lupus erythematosus (SLE); however, there is heterogeneity in its clinical use. This consensus aims to bridge the gap in SLE treatment by providing practical and valuable recommendations for health professionals. METHODS: The methodology used is based on a systematic literature review and a nominal group technique (NGT). A ten-member scientific committee formulated eight clinically relevant questions. First, a systematic review was conducted to identify the available evidence, which the scientific committee evaluated to developed recommendations based on their expertise, achieving consensus through NGT. RESULTS: 1673 titles and abstracts were screened, and 43 studies were included for meeting the inclusion criteria. The scientific committee established 11 recommendations for HCQ use in initiation, maintenance, and monitoring, considering benefits and potential adverse effects of HCQ. Unanimous agreement was achieved on all recommendations. CONCLUSIONS: The available evidence supports HCQ's effectiveness and safety for SLE. Individualized assessment of the initial HCQ dose is important, especially in situations requiring dose reduction or discontinuation. This risk-benefit assessment, specifically focusing on the balance between retinal toxicity and the risk of SLE relapse, should guide decisions regarding medication withdrawal, considering disease activity, risk factors, and HCQ potential benefits. Close monitoring is essential for optimal disease management and minimize potential risks, such as QT prolongation or retinal toxicity.

OBJECTIVE: To evaluate cognitive function in patients with rheumatoid arthritis (RA) and inflammatory activity. PATIENTS AND METHODS: We performed a cross-sectional study of a cohort of patients with RA initiating their first biological treatment due to moderate-to-high inflammation and a healthy control group (no inflammatory diseases) matched for age, sex and educational level. All participants underwent a comprehensive neuropsychological assessment, with cognitive impairment defined as a Montreal Cognitive Assessment (MoCA) score<26. Additional assessments included various cognitive tests (STROOP, forward and backward digit spans), anxiety and depression scales (Hospital Anxiety and Depression Scale), quality of life measures (Quality of Life-Rheumatoid Arthritis) and average inflammatory activity according to the 28-joint Disease Activity Score (DAS28)-C-reactive protein (CRP) into high activity (DAS28≥3.2) and low activity (DAS28<3.2) groups, also CRP levels and interleukin 6 (IL-6) levels were measured using an ELISA. RESULTS: The study population comprised 140 participants, 70 patients with RA and 70 controls. Patients more frequently experienced cognitive impairment than controls (60% vs 40%; p=0.019) and had lower mean (SD) values in the MoCA (23.6 (3.9) vs 25.1 (3.4); p=0.019. As for subtests of the MoCA, involvement was more marked in patients than in controls for the visuospatial-executive (p=0.030), memory (p=0.026) and abstraction (p=0.039) domains. Additionally, patients scored lower on executive function, as assessed by the backward digit span test (4.0 (1.7) vs 4.7 (1.9); p=0.039). Cognitive impairment is associated with age and a lower educational level in the general population, and among patients with RA with educational level, obesity and average inflammatory activity (DAS28, CRP, and IL-6). CONCLUSIONS: Patients with RA with high inflammatory activity are more susceptible to cognitive impairment, which specifically affects the domains of visuospatial, memory, abstraction and executive function.

AIM: To describe the impact of the COVID-19 on the psychosocial health of patients with rheumatoid arthritis (RA), spondyloarthritis (SpA), and systemic lupus erythematosus (SLE). DESIGN: Longitudinal observational study of a series of patients with rheumatic disease. METHODS: The main outcome measure was impairment of the ability to participate in social activities, as measured using the PROMIS-APS instrument Short Form-8a. We evaluated social activities in various settings and performed a multivariate analysis to study the association between worsening of social participation during the COVID-19 pandemic and implicated factors. RESULTS: One hundred and twenty-five patients had completed the prospective follow-up: 40 with AR (32%), 42 with SpA (33.6%), and 43 with SLE (34.4%). Overall, poorer mean PROMIS scores were recorded after the COVID-19 pandemic for: satisfaction with social roles (p=0.029), depression (p=0.039), and ability to participate in social activities (p=0.024). The factors associated with ability to participate in social activities after the COVID-19 pandemic were older age (ß=-0.215; p=0.012), diagnosis of SLE (ß=-0.203; p=0.015), depression (ß=-0.295; p=0.003) and satisfaction with social roles (ß=0.211; p=0.037). CONCLUSION: The ability to participate in social activities after the COVID-19 pandemic is affected in patients with rheumatic disease, especially in SLE.

OBJECTIVES: To describe the severity and impact of gastrointestinal involvement in patients with systemic sclerosis (SSc) and identify associated factors. PATIENTS AND METHODS: Non-controlled cross-sectional study of patients with SSc (2013 American College of Rheumatology/European League Against Rheumatism criteria). The main variables were severity of gastrointestinal involvement according to the University of California, Los Angeles Scleroderma Clinical Trials Consortium Gastrointestinal Tract 2.0 instrument (UCLA SCTC GIT 2.0) and dysphagia according to the Eating Assessment Tool-10 (EAT-10). We evaluated reflux, distension, diarrhoea, faecal soilage, constipation, emotional well-being and social functioning, as well as dysphagia. Clinical and epidemiological data were collected using the Mini Nutritional Assessment Short Form (MNA-SF) and the EuroQol-5D-3L. The degree of skin fibrosis was assessed using the modified Rodnan skin score (mRSS). Multivariate models were constructed to analyse factors associated with gastrointestinal involvement and dysphagia. RESULTS: Of the 75 patients with SSc included, 58.7% had moderate, severe or very severe reflux, 57.4% had constipation according to UCLA SCTC GIT 2.0 and 49.7% had abdominal distension. Gastrointestinal symptoms interfered significantly with social functioning (42.7%) and emotional well-being (40.0%). Dysphagia (EAT-10≥3) was recorded in 52% of patients, and according to MNA-SF poor nutrition in 30.7%, and clear malnutrition requiring a nutritional intervention in 5.3%. Multivariate adjustment revealed an association between severity of gastrointestinal symptoms according to the mRSS (ß=0.249; p=0.002) and Visual Analogue Scale 3-Level EuroQol-5D (VAS-EQ-5D-3L) (ß=-0.302; p=0.001), whereas presence of dysphagia was associated with the mRSS (OR=2.794; p=0.015), VAS-EQ-5D-3L (OR=0.950; p=0.005) and malnutrition (MNA-SF≤7; OR=3.920; p=0.041). CONCLUSIONS: Patients with SSc frequently present severe gastrointestinal symptoms. These are associated with poor quality of life, more severe skin involvement and malnutrition.

OBJECTIVE: To develop an improved score for prediction of severe infection in patients with systemic lupus erythematosus (SLE), namely, the SLE Severe Infection Score-Revised (SLESIS-R) and to validate it in a large multicentre lupus cohort. METHODS: We used data from the prospective phase of RELESSER (RELESSER-PROS), the SLE register of the Spanish Society of Rheumatology. A multivariable logistic model was constructed taking into account the variables already forming the SLESIS score, plus all other potential predictors identified in a literature review. Performance was analysed using the C-statistic and the area under the receiver operating characteristic curve (AUROC). Internal validation was carried out using a 100-sample bootstrapping procedure. ORs were transformed into score items, and the AUROC was used to determine performance. RESULTS: A total of 1459 patients who had completed 1 year of follow-up were included in the development cohort (mean age, 49±13 years; 90% women). Twenty-five (1.7%) had experienced ≥1 severe infection. According to the adjusted multivariate model, severe infection could be predicted from four variables: age (years) ≥60, previous SLE-related hospitalisation, previous serious infection and glucocorticoid dose. A score was built from the best model, taking values from 0 to 17. The AUROC was 0.861 (0.777-0.946). The cut-off chosen was ≥6, which exhibited an accuracy of 85.9% and a positive likelihood ratio of 5.48. CONCLUSIONS: SLESIS-R is an accurate and feasible instrument for predicting infections in patients with SLE. SLESIS-R could help to make informed decisions on the use of immunosuppressants and the implementation of preventive measures.

Objective: To describe severe infection, foci of infection, microorganisms, associated factors, and impact on mortality in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD). Patients and methods: The study was based on a multicenter prospective cohort of patients with RA-ILD followed up from 2015 to 2023. The main outcome measures were incident severe infection and fatal infection. We evaluated infectious foci, etiologic agents, vaccination status, variables associated with lung function, and clinical-therapeutic variables in RA. The incidence rate (IR) for infection and mortality was calculated per 100 person-years, and 3 multivariate models were constructed to explore factors associated with infection. Results: We followed up 148 patients with RA-ILD for a median 56.7 months (699.3 person-years). During this period, 142 patients (96%) had at least 1 infection. A total of 368 infectious episodes were recorded, with an IR of 52.6 per 100 person-years. Of the 48 patients who died, 65% did so from infection. Respiratory infections were the most common first infection (74%), infection overall (74%), and fatal infection (80%) and were caused mostly by SARS CoV-2, Streptococcus pneumoniae, Pseudomonas aeruginosa, and influenza A virus. The factors associated with an increased risk of infection and death in patients with RA-ILD were age, inflammatory activity, and therapy with corticosteroids and immunosuppressants. Conclusion: Patients with RA-ILD have a high risk of serious infection, especially respiratory infection. Infection develops early, is recurrent, and is frequently fatal. The presence of associated factors such as advanced age, joint inflammation, and treatment highlight the importance of integrated and preventive medical care.

BACKGROUND: In rheumatoid arthritis (RA), the activation of T and B cell clones specific for self-antigens leads to the chronic inflammation of the synovium. Here, we perform an in-depth quantitative analysis of the seven chains that comprise the adaptive immune receptor repertoire (AIRR) in RA. RESULTS: In comparison to controls, we show that RA patients have multiple and strong differences in the B cell receptor repertoire including reduced diversity as well as altered isotype, chain, and segment frequencies. We demonstrate that therapeutic tumor necrosis factor inhibition partially restores this alteration but find a profound difference in the underlying biochemical reactivities between responders and non-responders. Combining the AIRR with HLA typing, we identify the specific T cell receptor repertoire associated with disease risk variants. Integrating these features, we further develop a molecular classifier that shows the utility of the AIRR as a diagnostic tool. CONCLUSIONS: Simultaneous sequencing of the seven chains of the human AIRR reveals novel features associated with the disease and clinically relevant phenotypes, including response to therapy. These findings show the unique potential of AIRR to address precision medicine in immune-related diseases.

BACKGROUND & OBJECTIVES: This study aimed to: 1) analyze the inflammatory profile of Rheumatoid Arthritis (RA) patients, identifying clinical phenotypes associated with cardiovascular (CV) risk; 2) evaluate biologic and targeted-synthetic disease-modifying antirheumatic drugs (b-DMARDs and ts-DMARDs': TNFi, IL6Ri, JAKinibs) effects; and 3) characterize molecular mechanisms in immune-cell activation and endothelial dysfunction. PATIENTS & METHODS: A total of 387 RA patients and 45 healthy donors were recruited, forming three cohorts: i) 208 RA patients with established disease but without previous CV events; ii) RA-CVD: 96 RA patients with CV events, and iii) 83 RA patients treated with b-DMARDs/ts-DMARDs for 6 months. Serum inflammatory profiles (cytokines/chemokines/growth factors) and NETosis/oxidative stress-linked biomolecules were evaluated. Mechanistic in vitro studies were performed on monocytes, neutrophils and endothelial cells (EC). RESULTS: In the first RA-cohort, unsupervised clustering unveiled three distinct groups: cluster 3 (C3) displayed the highest inflammatory profile, significant CV-risk score, and greater atheroma plaques prevalence. In contrast, cluster 1 (C1) exhibited the lowest inflammatory profile and CV risk score, while cluster 2 (C2) displayed an intermediate phenotype. Notably, 2nd cohort RA-CVD patients mirrored C3's inflammation. Treatment with b-DMARDs or ts-DMARDs effectively reduced disease-activity scores (DAS28) and restored normal biomolecules levels, controlling CV risk. In vitro, serum from C3-RA or RA-CVD patients increased neutrophils activity and CV-related protein levels in cultured monocytes and EC, which were partially prevented by pre-incubation with TNFi, IL6Ri, and JAKinibs. CONCLUSIONS: Overall, analyzing circulating molecular profiles in RA patients holds potential for personalized clinical management, addressing CV risk and assisting healthcare professionals in tailoring treatment, ultimately improving outcomes.

OBJECTIVE: To evaluate sleep disorders and associated factors in patients with rheumatoid-arthritis-associated interstitial lung disease (RA-ILD). METHODS: We performed an observational study of 35 patients with RA-ILD (cases) and 35 age- and sex-matched RA patients without ILD (controls). We evaluated sleep disorders (Oviedo Sleep Questionnaire), positive psychological factors (resilience using the Wagnild and Young Resilience Scale, emotional intelligence using the 24-item Trait Meta-Mood Scale), anxiety and depression (Hospital Anxiety and Depression Scale), quality of life (36-item short-form survey), and fatigue (Functional Assessment of Chronic Illness Therapy Questionnaire). Other variables studied included the Charlson Comorbidity Index (CCI) and RA activity according to the DAS28-ESR. RESULTS: Compared to the controls, the cases were characterized by poorer sleep quality with a higher prevalence of insomnia (42% vs. 20%; p = 0.039), greater severity of insomnia (p = 0.001), and lower sleep satisfaction (p = 0.033). They also had poorer resilience and emotional recovery and more severe anxiety and depression. A diagnosis of ILD was the only factor independently associated with the three dimensions of sleep quality. The predictors of poorer sleep satisfaction in patients with RA-ILD were age (ß = -0.379), DAS28-ESR (ß = -0.331), and usual interstitial pneumonia pattern (ß = -0.438). The predictors of insomnia were DAS28-ESR (ß = 0.294), resilience (ß = -0.352), and CCI (ß = 0.377). CONCLUSIONS: RA-ILD is associated with significant sleep disorders. RA-ILD seems to be an independent risk factor for sleep alterations, with a greater impact on insomnia. Age, disease activity, and comorbidity also play a role in sleep disorders in patients with RA-ILD.
RESUMEN
Background: Spondyloarthritis (SpA) is a group of related but phenotypically distinct inflammatory disorders that include axial SpA (axSpA) and psoriatic arthritis (PsA). Information on the characteristics and management of these patients in the real world remains scarce. Objectives: To explore the characteristics and management [disease activity assessment and treatment with secukinumab (SEC) or other biologic disease-modifying antirheumatic drugs (bDMARDs)] of axSpA and PsA patients using natural language processing (NLP) in Electronic Health Records (EHRs). Design: National, multicenter, observational, and retrospective study. Methods: We analyzed free-text and structured clinical information from EHR at three hospitals. All adult patients with axSpA, PsA or non-classified SpA from 2018 to 2021 with minimum follow-up of three months were included when starting SEC or other bDMARDs. Clinical variables were extracted using EHRead® technology based on Systemized Nomenclature of Medicine-Clinical Terms (SNOMED CT) terminology. Results: Out of 887,735 patients, 758 were included, of which 328 had axSpA [58.5% male; mean (SD) age of 50.7 (12.7) years], 365 PsA [54.8% female, 53.9 (12.4) years], and 65 non-classified SpA. Mean (SD) time since diagnosis was 36.8 (61.0) and 24.1 (35.2) months for axSpA and PsA, respectively. Only 116 axSpA patients (35.3%) had available Ankylosing Spondylitis Disease Activity Score (ASDAS) or Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at bDMARD onset, of which 61 presented active disease. Disease Activity in PSoriatic Arthritis (DAPSA) or Disease Assessment Score - 28 joints (DAS-28) values at bDMARD onset were available for only 61 PsA (16.7%) patients, with 23 of them having active disease. The number of patients with available tender joint count or swollen joint count assessment was 68 (20.7%) and 59 (18%) for axSpA, and 115 (31.5%) and 119 (32.6%) for PsA, respectively. SEC was used in 63 (19.2%) axSpA patients and in 63 (17.3%) PsA patients. Conclusion: Using NLP, the study showed that around one-third of axSpA and one-sixth of PsA patients have disease activity assessments with ASDAS/BASDAI or DAPSA/DAS-28, respectively, highlighting an area of improvement in these patients' management.
Investigating axial spondyloarthritis and psoriatic arthritis patients using natural language processing We conducted a study in Spain to better understand patients with specific rheumatic conditions known as axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA). To analyze their characteristics, we used a computer technology called EHRead, which uses Natural Language Processing (NLP) to analyze free text from electronic health records. Out of a large group of patients, we focused on 758 individuals who had axSpA or PsA. Most of the axSpA patients were men, and they were around 51 years old on average. For the PsA patients, most were women, and their average age was about 54 years. We analyzed outcomes and treatments of these patients. Our findings showed that we can describe and assess a cohort of patients from real world using NLP. Besides, only about one-third of axSpA patients and one-sixth of PsA patients had their respective outcomes completely assessed, which indicates that there is potential room for improvement in the management of axSpA and PsA. The most promising feature in our study is the use of NLP, an artificial intelligence technology that helps us understand information in medical records written in free text. This can help us explore the characteristics of patients and their management in the real world, bringing an opportunity to enhance the care of patients with axSpA and PsA.
RESUMEN
OBJECTIVE: To describe the frequency of malnutrition in older patients with rheumatoid arthritis (RA) and investigate associated risk factors. METHODS: This multicenter, cross-sectional study included participants aged ≥65 years who met the 2010 ACR/EULAR criteria for RA. Nutritional status was assessed using the Mini Nutritional Assessment Short Form (MNA-SF) and based on variables, such as albumin level, the Geriatric Nutritional Risk Index (GNRI), and vitamin D. Data were also collected on epidemiological variables, inflammatory disease activity, quality of life, physical function, and frailty. Multivariate models were used to study factors associated with nutritional status. RESULTS: The study population comprised 76 RA patients aged ≥65 years, of whom 68.4% had a normal nutritional status, and 31.5% had an impaired nutritional status: 28.9% were at risk of malnutrition, and 2.6% were malnourished. Additionally, 10% had albumin levels <3.8 g/L. Patients with impaired nutritional status had poorer quality of life and physical function. The factors associated with compromised nutritional status (OR [95% CI]) were age (1.0 [1.0-1.1]; p = 0.035), DAS28-ESR (1.8 [1.0-3.2]; p = 0.024), and EuroQoL-5D-5L (0.9 [0.9-0.9]; p = 0.040). Furthermore, the GNRI was associated with the MNA score (0.06 [0.0-0.1]; p = 0.014). CONCLUSIONS: Approximately one-third of older patients with RA have impaired nutritional status. Older age, higher inflammatory disease activity, and decreased quality of life are associated with impaired nutritional status. The MNA and GNRI are valuable tools for assessing the nutritional status of patients with RA.

OBJECTIVE: To describe the prevalence of sarcopenia in rheumatoid arthritis (RA) patients aged ≥65 years and identify the risk factors associated with sarcopenia. METHODS: This is a multicenter, controlled, cross-sectional study of 76 RA patients and 76 age- and sex-matched healthy controls. Sarcopenia was defined according to the revised criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2). Whole-body dual-energy X-ray absorptiometry (DXA) was performed. Binary regression was used to assess the relationship between sarcopenia and sex, age, duration of RA, Mini Nutritional Assessment (MNA) score, and Short Physical Performance Battery (SPPB) score in patients with RA. RESULTS: Nearly 80% of participants were female, and the average age was >70 years. Patients with RA had lower muscle mass and greater adiposity (fat-to-muscle ratio mean [SD] 0.9 [0.2] vs. 0.8 [0.2]; p = 0.017) than controls, mainly in the central area (android/gynoid ratio, median [p25-p75]: 1.0 [0.9-1.2] vs. 0.9 [0.8-1.1]; p < 0.001). Twelve patients (15.8%) and three controls (3.9%) had confirmed sarcopenia (p = 0.014). Sarcopenic obesity was observed in 8/76 patients with RA (10.5%) and in 1/76 controls (1.3%) (p = 0.016). The factors associated with sarcopenia were male sex (OR [95% CI]: 9.3 [1.1-80.4]; p = 0.042), disease duration (OR [95% CI]: 1.1 [1.0-1.2]; p = 0.012), and nutritional status according to the MNA (OR [95% CI]: 0.7 [0.5-0.9]; p = 0.042). CONCLUSIONS: Our results suggest that patients with RA aged ≥65 years may be at increased risk for sarcopenia, adiposity, and malnutrition (especially male patients with long-standing disease) and have poor nutritional status.

This study aimed to identify inflammatory factors and soluble cytokines that act as biomarkers in the diagnosis and prognosis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD). We performed a nested prospective observational case-control study of patients with RA-ILD matched by sex, age, and time since the diagnosis of RA. All participants underwent pulmonary function testing and high-resolution computed tomography. ILD was defined according to the criteria of the American Thoracic Society/European Respiratory Society; the progression of lung disease was defined as the worsening of FVC > 10% or DLCO > 15%. Inflammation-related variables included the inflammatory activity measured using the DAS28-ESR and a multiplex cytokine assay. Two Cox regression models were run to identify factors associated with ILD and the progression of ILD. The study population comprised 70 patients: 35 patients with RA-ILD (cases) and 35 RA patients without ILD (controls). A greater percentage of cases had higher DAS28-ESR (p = 0.032) and HAQ values (p = 0.003). The variables associated with RA-ILD in the Cox regression analysis were disease activity (DAS28) (HR [95% CI], 2.47 [1.17-5.22]; p = 0.017) and high levels of ACPA (HR [95% CI], 2.90 [1.24-6.78]; p = 0.014), IL-18 in pg/mL (HR [95% CI], 1.06 [1.00-1.12]; p = 0.044), MCP-1/CCL2 in pg/mL (HR [95% CI], 1.03 [1.00-1.06]; p = 0.049), and SDF-1 in pg/mL (HR [95% CI], 1.00 [1.00-1.00]; p = 0.010). The only variable associated with the progression of ILD was IL-18 in pg/mL (HR [95% CI], 1.25 [1.07-1.46]; p = 0.004). Our data support that the inflammatory activity was higher in patients with RA-ILD than RA patients without ILD. Some cytokines were associated with both diagnosis and poorer prognosis in patients with RA-ILD.

OBJECTIVE: To analyze the intestinal microbiota of patients with rheumatoid arthritis (RA) and obesity and a higher percentage of fatty tissue. METHODS: Nested case-control study of 80 RA patients and 80 age and sex-matched controls. Obesity was defined as a body mass index ≥ 30, and body composition using dual-energy x-ray absorptiometry. The gut microbiota was analyzed using 16 S rRNA gene sequencing; bioinformatics analysis was performed using QIIME2 and PICRUSt. Other variables included averaged 28-joint Disease Activity Score (DAS28-ESR), cytokines and adipokines. Two multivariate were constructed with obesity and fat mass index (FMI). RESULTS: Obesity was more frequent in RA patients than in controls (36.3 % vs 25.1 %; p = 0.026), as was a higher FMI value (mean [SE]=11.6 [3.9] vs 10.2 [3.9]; p = 0.032). Alpha and beta diversity analysis revealed differences in gut microbiota between RA patients with and without obesity. Dialister and Odoribacter were more abundant in RA patients with obesity than in RA patients without obesity, while the genus Clostridium was more abundant in RA patients without obesity. The factors associated with obesity in RA patients were age (OR [95 % CI], 1.09 [1.02-1.17]), mean DAS28-ESR (OR [95 % CI], 1.46 [1.12-1.67]), leptin levels (OR [95 % CI], 1.06 [1.01-1.10]), the genus Dialister (OR [95 % CI], 1.03 [1.01-1.07]), and the genus Clostridium (OR [95 % CI], 0.013 [0.00-0.36]). The associations observed for FMI were similar. CONCLUSIONS: In patients with RA, obesity, and a higher percentage of fatty tissue, intestinal microbiota differed from that of controls and of the other patients. The genus Dialister was associated with obesity and FMI.

OBJECTIVES: To describe comorbid conditions in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and to analyze factors associated with multimorbidity. METHODS: Nested case-cohort study of 2 prospective cohorts: one with RA-ILD (cases) and another with RA but not ILD (controls). The cohorts were matched for age, sex, and time since diagnosis. Multimorbidity was defined as the co-occurrence of 2 or more chronic diseases, in addition to RA and ILD. We evaluated the comorbid conditions included in the Charlson Comorbidity Index, cardiovascular risk factors, neuropsychiatric conditions, and other frequent conditions in RA. We also recorded clinical-laboratory variables, inflammatory activity according to the 28-joint Disease Activity Score, C-reactive protein (CRP), physical function, and pulmonary function. We performed 2 multivariate analyses to identify factors associated with multimorbidity in RA and RA-ILD. RESULTS: The final study population comprised 110 cases and 104 controls. Multimorbidity was more frequent among cases than controls (80 [72.7] vs 60 [57.7]; p = 0.021). In both groups, multimorbidity was associated with ILD (OR [95% CI] 1.92 [1.03-3.59]; p = 0.039), age (OR [95% CI] 1.05 [1.01-1.08]; p = 0.004), CRP (OR [95% CI] 1.16 [1.05-1.29]; p = 0.003), and erosions (OR [95% CI] 1.05 [1.01-1.08]; p = 0.004); in the cases, it was associated with CRP (OR [95% CI] 1.17 [1.01-1.35]; p = 0.027), anti-citrullinated peptide antibody (OR [95% CI] 1.23 [1.14-13.02]; p = 0.049), and forced vital capacity (OR [95% CI] 0.79 [0.96-0.99]; p = 0.036). CONCLUSION: In patients with RA, multimorbidity was associated with ILD, systemic inflammation, and advanced age.

Objective: To evaluate the effectiveness and safety of tocilizumab (TCZ) monotherapy in biologic-naïve patients with rheumatoid arthritis (RA) versus patients with previous biologic exposure in a real-world setting. Materials and methods: Non-controlled clinical-trial, 32-week prospective multicenter study including RA patients with moderate-severe disease activity starting TCZ in monotherapy who had a prior inadequate response or were intolerant to methotrexate (MTX). Effectiveness according to EULAR response evaluated at 24-week and safety at 32-weekwere assessed. Results: Of the 93 were enrolled of whom 84 (90%) were eligible for the effectiveness analysis. Biologic-naïve patients (n=46, 54.8%) were younger (51.5 versus 57.9) with shorter disease duration (6.4 versus 13.3) but presented similar comorbidities in comparison with non-naïve patients. DAS28 remission was achieved in a higher percentage in the group of patients with prior biological treatment. 89 adverse events (AE) were recorded in 50 patients, most of them non-serious AE (non-SAE) (86.3%). Conclusions: In a real world setting, TCZ exhibit similar effectiveness and safety in monotherapy in patients with RA regardless previous exposure to other biologic therapies. This study provides additional and valuable real-world findings on the use of TCZ in patients with RA.(AU)
Objetivo: Evaluar la efectividad y seguridad de la monoterapia con tocilizumab (TCZ) en pacientes con artritis reumatoide (AR) sin tratamiento biológico en comparación con pacientes con exposición previa a biológico en un entorno real.Materiales y métodos: Ensayo clínico no controlado, estudio multicéntrico prospectivo de 32 semanas que incluyó pacientes con AR con actividad de la enfermedad moderada-grave que comenzaron con TCZ en monoterapia y que tuvieron una respuesta inadecuada previa o fueron intolerantes al metotrexato. La eficacia de acuerdo con la respuesta EULAR fue evaluada a las 24 semanas y la seguridad a las 32 semanas. Resultados: De los 93 pacientes seleccionados, 84 (90%) fueron elegibles para el análisis de efectividad. Los pacientes sin tratamiento biológico previo (n=46, 54,8%) eran más jóvenes (51,5 frente a 57,9 años), con una duración más corta de la enfermedad (6,4 frente a 13,3 años), pero presentaban comorbilidades similares en comparación con los pacientes con tratamiento previo. La remisión de DAS28 se logró en un mayor porcentaje en el grupo de pacientes con tratamiento biológico previo. Se registraron 89 eventos adversos en 50 pacientes, la mayoría de ellos no graves (86,3%). Conclusiones: En un entorno del mundo real, TCZ exhibe una eficacia y seguridad similares en monoterapia en pacientes con AR, independientemente de la exposición previa a otras terapias biológicas. Este estudio proporciona hallazgos adicionales y valiosos en el contexto del mundo real sobre el uso de TCZ en pacientes con AR.(UA)

Objectives: To describe the characteristics of patients between late-onset rheumatoid arthritis (LORA) with young-onset (YORA), and analyze their association with cumulative inflammatory burden. Methods: We performed a nested cohort study in a prospective cohort comprising 110 patients with rheumatoid arthritis (RA) and 110 age- and sex-matched controls. The main variable was cumulative inflammatory activity according to the 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR). High activity was defined as DAS28 ≥ 3.2 and low activity as DAS28 < 3.2. The other variables recorded were inflammatory cytokines, physical function, and comorbid conditions. Two multivariate models were run to identify factors associated with cumulative inflammatory activity. Results: A total of 22/110 patients (20%) met the criteria for LORA (≥ 60 years). Patients with LORA more frequently had comorbid conditions than patients with YORA and controls. Compared with YORA patients, more LORA patients had cumulative high inflammatory activity from onset [13 (59%) vs. 28 (31%); p = 0.018] and high values for CRP (p = 0.039) and IL-6 (p = 0.045). Cumulative high inflammatory activity in patients with RA was associated with LORA [OR (95% CI) 4.69 (1.49-10.71); p = 0.008], smoking [OR (95% CI) 2.07 (1.13-3.78); p = 0.017], anti-citrullinated peptide antibody [OR (95% CI) 3.24 (1.15-9.13); p = 0.025], average Health Assessment Questionnaire (HAQ) score [OR (95% CI) 2.09 (1.03-14.23); p = 0.034], and physical activity [OR (95% CI) 0.99 (0.99-0.99); p = 0.010]. The second model revealed similar associations with inflammatory activity in patients with LORA. Conclusion: Control of inflammation after diagnosis is poorer and comorbidity more frequent in patients with LORA than in YORA patients and healthy controls.
RESUMEN
This study aimed to evaluate the role of microRNAs (miRNA) as biomarkers of treatment response in rheumatoid arthritis (RA) patients through a systematic review of the literature. The MEDLINE and Embase databases were searched for studies including RA-diagnosed patients treated with disease-modifying antirheumatic drugs (DMARDs) that identify miRNAs as response predictors. Review inclusion criteria were met by 10 studies. The main outcome of the study was the response to treatment, defined according to EULAR criteria. A total of 839 RA patients and 67 healthy donors were included in the selected studies. RA patients presented seropositivity for the rheumatoid factor of 74.7% and anti-citrullinated C-peptide antibodies of 63.6%. After revision, 15 miRNAs were described as treatment response biomarkers for methotrexate, anti-tumour necrosis factor (TNF), and rituximab. Among treatments, methotrexate presented the highest number of predictor miRNAs: miR-16, miR-22, miR-132, miR-146a and miR-155. The most polyvalent miRNAs were miR-146a, predicting response to methotrexate and anti-TNF, and miR-125b, which predicts response to infliximab and rituximab. Our data support the role of miRNAs as biomarkers of treatment response in RA and point to DMARDs modifying the miRNAs expression. Nevertheless, further studies are needed since a meta-analysis that allows definitive conclusions is not possible due to the lack of studies in this field.
