ABSTRACT
OBJECTIVES: A subset of human circulating FoxP3+ regulatory T cells expresses CD39 (cTreg39+) and hydrolyses pro-inflammatory adenine nucleotides released at inflammatory foci, rendering the anti-inflammatory agent adenosine. Methotrexate (MTX), inhibiting ATIC, enhances the extrusion of adenine nucleotides and may help Treg39+ cells control inflammation. Therefore, we examined the relation of cTreg39+ cells with the effect of MTX in early Rheumatoid Arthritis (eRA). METHODS: Freshly isolated peripheral blood lymphocytes from 98 untreated eRA patients and 98 healthy controls (HC) were examined by cytometry. Twelve months (12m) after initiating MTX, 82 patients were clinically re-evaluated and cytometry was repeated in 40 of them. The effect of MTX on Treg cell potency was assessed in Treg/Tresp cocultures. RESULTS: The baseline (0m) cTreg39+ cell frequency was elevated in eRA above HC levels. Patients who reached low disease activity at 12 months (12m-LDA, DAS28-ESR≤ 3.2, n = 51) had presented with a significantly higher 0m cTreg39+ frequency vs those who did not (n = 31). The 0m cTreg39+ cutoff for attaining 12 m-LDA was 42.0% (Sensitivity=90.4%/Specificity=96.8%). At 12m, the cTreg39+ frequency was no longer elevated but its association with disease activity remained: it was still significantly higher in patients who had reached LDA vs those who had not. In vitro, MTX augmented the Treg39+ cell potency but had no effect on Treg39- cells. CONCLUSION: MTX cooperates with Treg39+ cells and the baseline cTreg39+ frequency predicts the response to MTX in eRA. In addition, the transiently elevated baseline cTreg39+ frequency in eRA may provide a slot for prompt MTX initiation.
ABSTRACT
OBJECTIVES: To evaluate the survival of different biologic or targeted-synthetic disease-modifying antirheumatic drugs (b/tsDMARD) administered after fulfilling difficult-to-treat rheumatoid arthritis (D2TRA) criteria, and to assess factors related to treatment discontinuation. METHODS: Retrospective study including D2TRA patients. Drug retention of the b/tsDMARD administered after fulfilling D2TRA was assessed by Kaplan-Meier plots and the log-rank test. Cox hazard models were used to identify factors affecting treatment discontinuation. RESULTS: Of the 122 patients included, 75 maintained active treatment (61.5%) with a subsequent line after D2T compared to 47 (38.5%) who discontinued and required more successive lines of b/tsDMARDs. The median survival of the treatments was 78.3(7.6) months and the treatment after D2T with the better rate of survival was rituximab, followed by JAKi and IL6Ri, while worse survival rates were associated with abatacept and TNFi. Significant differences were noted among b/tsDMARDs (log-rank p < 0.01) and to evaluate these differences, a Cox regression was performed, taking each b/tsDMARD as a reference and comparing it with the others. DAS28 values 6-months after initiation of treatment were higher in those patients who discontinued treatment [4.4(1.2) vs 3.5(1.3), p = 0.01]. The multivariate cox regression model revealed that treatment choice after D2T [HR = 1.26(95%CI 1.06-1.05)] and lower DAS28 values at 6 months [HR = 1.49(95%CI 1.16-1.52)] were independent risk factors associated with treatment discontinuation. CONCLUSIONS: Once patients met the D2TRA criteria, the subsequent line of b/tsDMARDs with the best survival rates were rituximab, JAKi and IL6Ri. Moreover, DAS28 at 6-months of treatment after D2T was an independent risk factor for drug discontinuation. Key Points ⢠Rituximab, IL6Ri and JAKi have better retention rates in patients after fulfilling D2TRA criteria ⢠Clinical disease activity in the first six months after fulfillment of D2TRA criteria is an independent risk factor of subsequent treatment survival.

OBJECTIVES: To investigate whether hypoechoic wall thickness is influenced by the systole or diastole moment in the cardiac cycle and if this can influence ultrasound (US) assessments of giant cell arteritis (GCA). METHODS: US videos of 100 consecutive patients (50 with GCA, 50 without) performed between January 2021 and June 2023 were reviewed. Intima-media thickness (IMT) of temporal (including common trunk, frontal and parietal branches), axillary and subclavian arteries were measured at two different time points, at systolic peak (SP) and at the end-diastole (ED). Differences between SP IMT and ED IMT, as well as in the halo count (HC) and in the OMERACT GCA Ultrasonography Score (OGUS) between these two times, were analyzed. RESULTS: IMT was significantly higher (4.8-5%) at ED in all arteries, in both GCA and non-GCA groups. HC and OGUS were also higher in ED in both groups. In 4 non-GCA patients (8%), the HC was positive in ED and negative in SP; in all of them the HC in ED was 1. In the GCA group, the timing of the cardiac cycle did not influence the final US diagnosis; however, it did modify the HC in 14 patients (28%). CONCLUSION: IMT can fluctuate during the cardiac cycle, with higher measurements occurring at ED. This variability could potentially impact the accuracy of US diagnoses and assessments of GCA. If further research corroborates these findings, it may be imperative to revise the guidelines for employing US in diagnosing GCA in order to incorporate these nuanced aspects.
ABSTRACT
BACKGROUND: Rheumatic and musculoskeletal diseases (RMDs) are chronic diseases that may alternate between asymptomatic periods and flares. These conditions require complex treatments and close monitoring by rheumatologists to mitigate their effects and improve the patient's quality of life. Often, delays in outpatient consultations or the patient's difficulties in keeping appointments make such close follow-up challenging. For this reason, it is very important to have open communication between patients and health professionals. In this context, implementing telemonitoring in the field of rheumatology has great potential, as it can facilitate the close monitoring of patients with RMDs. The use of these tools helps patients self-manage certain aspects of their disease. This could result in fewer visits to emergency departments and consultations, as well as enable better therapeutic compliance and identification of issues that would otherwise go unnoticed. OBJECTIVE: The main objective of this study is to evaluate the implementation of a hybrid care model called the mixed attention model (MAM) in clinical practice and determine whether its implementation improves clinical outcomes compared to conventional follow-up. METHODS: This is a multicenter prospective observational study involving 360 patients with rheumatoid arthritis (RA) and spondylarthritis (SpA) from 5 Spanish hospitals. The patients will be followed up by the MAM protocol, which is a care model that incorporates a digital tool consisting of a mobile app that patients can use at home and professionals can review asynchronously to detect incidents and follow patients' clinical evolution between face-to-face visits. Another group of patients, whose follow-up will be conducted in accordance with a traditional face-to-face care model, will be assessed as the control group. Sociodemographic characteristics, treatments, laboratory parameters, assessment of tender and swollen joints, visual analog scale for pain, and electronic patient-reported outcome (ePRO) reports will be collected for all participants. In the MAM group, these items will be self-assessed via both the mobile app and during face-to-face visits with the rheumatologist, who will do the same for patients included in the traditional care model. The patients will be able to report any incidence related to their disease or treatment through the mobile app. RESULTS: Participant recruitment began in March 2024 and will continue until December 2024. The follow-up period will be extended by 12 months for all patients. Data collection and analysis are scheduled for completion in December 2025. CONCLUSIONS: This paper aims to provide a detailed description of the development and implementation of a digital solution, specifically an MAM. The goal is to achieve significant economic and psychosocial impact within our health care system by enhancing control over RMDs.

OBJECTIVE: CD4+CXCR5+PD-1hi follicular helper T (Tfh) cells dwell in the germinal centers (GCs) of lymphoid organs and participate in Rheumatoid Arthritis (RA) pathogenesis; the frequency of their circulating counterparts (cTfh-frequency) is expanded in RA and correlates with the pool of GC Tfh cells. Our objective was to study the effect of abatacept (ABT) or TNF blockers (TNFb) on the cTfh-frequency in RA. METHODS: Peripheral blood was drawn from seropositive-longstanding RA patients chronically receiving csDMARDS (n = 45), TNFb (n = 59), or ABT (n = 34), and healthy controls (HC) (n = 137). Also, patients with an incomplete response to csDMARDS (n = 41) who initiated TNFb (n = 19) or ABT (n = 22), were studied at 0 and 12 months. The cTfh-frequency was examined by cytometry. RESULTS: As compared with HC, an increased cTfh-frequency was seen in seropositive-longstanding RA chronically receiving csDMARDs or TNFb but not ABT. After escalating from csDMARDs, the cTfh-frequency did not vary in patients who were given TNFb but decreased to HC levels in those given ABT. In the ABT group, the baseline cTfh-frequency was higher for patients who attained 12M remission (12Mr), vs those who remained active (12Ma): 0m cutoff for remission >0.38% (Sens. 92%, Sp. 90%), OR 25.3. Conversely, in the TNFb group, the baseline cTfh-frequency was lower for 12Mr vs 12Ma: 0m cutoff for non-remission >0.44% (Sens. 67%, Sp. 90%), OR 8.5. CONCLUSION: ABT but not TNFb, is able to curtail the cTfh-frequency in RA. A higher baseline cTfh-frequency predicts a good response to ABT but a poor response to TNFb.
ABSTRACT
Introduction: RA patients are at higher risk of cardiovascular disease, influenced by therapies. Studying their cardiovascular and cardiometabolic proteome can unveil biomarkers and insights into related biological pathways. Methods: This study included two cohorts of RA patients: newly diagnosed individuals (n=25) and those with established RA (disease duration >25 years, n=25). Both cohorts were age and sex-matched with a control group (n=25). Additionally, a longitudinal investigation was conducted on a cohort of 25 RA patients treated with methotrexate and another cohort of 25 RA patients treated with tofacitinib for 6 months. Clinical and analytical variables were recorded, and serum profiling of 184 proteins was performed using the Olink technology platform. Results: RA patients exhibited elevated levels of 75 proteins that might be associated with cardiovascular disease. In addition, 24 proteins were increased in RA patients with established disease. Twenty proteins were commonly altered in both cohorts of RA patients. Among these, elevated levels of CTSL1, SORT1, SAA4, TNFRSF10A, ST6GAL1 and CCL18 discriminated RA patients and HDs with high specificity and sensitivity. Methotrexate treatment significantly reduced the levels of 13 proteins, while tofacitinib therapy modulated the expression of 10 proteins. These reductions were associated with a decrease in DAS28. Baseline levels of SAA4 and high levels of BNP were associated to the non-response to methotrexate. Changes in IL6 levels were specifically linked to the response to methotrexate. Regarding tofacitinib, differences in baseline levels of LOX1 and CNDP1 were noted between non-responder and responder RA patients. In addition, response to tofacitinib correlated with changes in SAA4 and TIMD4 levels. Conclusion: In summary, this study pinpoints molecular changes linked to cardiovascular disease in RA and proposes candidate protein biomarkers for distinguishing RA patients from healthy individuals. It also highlights how methotrexate and tofacitinib impact these proteins, with distinct alterations corresponding to each drug's response, identifying potential candidates, as SAA4, for the response to these therapies.

ABSTRACT
OBJECTIVES: To investigate the appearance of anti-drug antibodies (ADA) against infliximab (IFX) determined by drug-sensitive and drug-tolerant assays and their relationship with drug levels and drug survival. METHODS: This longitudinal observational study included 45 patients with rheumatoid arthritis (RA) and 61 with spondyloarthritis (SpA). Serum samples were obtained at weeks 2, 6, 12, 24, and 52. Serum IFX levels were measured by a capture enzyme-linked immunosorbent assay (ELISA) and ADA by an in-house drug-sensitive two-site (bridging) enzyme-linked immunosorbent assay (bELISA) and a commercially available drug-tolerant ELISA (IDK, Immundiagnostik, Germany). RESULTS: Anti-drug antibodies were detected earlier by IDK than by bELISA. Once ADA appeared, positivity persisted throughout the study period. Patients who were bELISA ADA+ had higher IDK ADA levels (than bELISA ADA- patients). Circulating IFX levels were detected in all patients except those found to be bELISA ADA+. Serum IFX levels were lower in IDK ADA+ than in IDK ADA-patients.Most patients (64%) discontinued due to inefficacy. The early onset of immunogenicity was related to IFX survival. Both in RA and SpA, the median survival (years) was shorter in patients with earlier development of ADA (IDK+ before or at week 24) than those who became IDK+ later (after week 24) or never developed ADA. CONCLUSION: A drug-tolerant assay detects ADA during IFX therapy earlier and more frequently than a drug-sensitive assay. The onset of immunogenicity detected by drug-tolerant assays is related to the subsequent detection of ADA by drug-sensitive assays and drug survival.
ABSTRACT
OBJECTIVES: Certolizumab pegol (CZP), an Fc-free antibody fragment, has shown stable serum levels and steady efficacy in the treatment of RA patients, irrespective of RF levels at baseline. Here, we examine, in clinical practice, the effect of baseline RF and ACPA levels on serum drug levels of IFX, ADL and CZP an Fc-free antibody fragment. METHODS: This is a retrospective study performed in real-world patients. We assessed 170 patients with RA: 90 (53%) received IFX, 48 (28%) ADL and 32 (19%) CZP. Demographic and clinical variables, RF and ACPA levels were obtained at the baseline visit (T0), and patients were stratified based on negative, low, medium, or high levels. After 6 months (T6) serum drug levels and anti-drug antibodies (ADAb), were computed. RESULTS: While CZP serum levels did not differ across RF groups at T6, high baseline RF was linked to lower serum drug levels compared to RF negative status in treatment with complete monoclonal antibodies IFX and ADL. No differences in disease activity measured by DAS28 at baseline were observed across RF quartiles in patients treated with IFX or ADL. ADAb was observed in 26 patients with IFX, 3 with ADL and 1 with CZP, following 6 months of treatment. Patients with high baseline RF levels dropped out more frequently by secondary non-response in IFX or ADL than CZP (80% vs. 75% vs. 33%, p=0.002). CONCLUSIONS: In this real word data evaluation, CZP serum levels were independent of RF levels in patients however patients with high baseline RF levels who obtained IFX or ADL had lower serum drug levels at 6 months than baseline RF-negative patients. In addition, secondary non-response was more frequent in patients with high RF levels treated with IFX and ADL.

BACKGROUND: There is a lack of outcome measures for the assessment of physical activity in patients with axial spondyloarthritis (axSpA). For this matter, the modified Short QUestionnaire to Assess Health (mSQUASH) was developed and validated, originally in Dutch. OBJECTIVE: To translate and cross-culturally adapt the mSQUASH into Spanish and to evaluate the equivalence of the translated version in patients with axSpA. METHODS: The mSQUASH was translated following forward-backward procedure according to the protocol of Beaton. Two bi-lingual translators produced independent forward translations of the mSQUASH into Spanish, and the versions were harmonized in a consensual version. Another translator back translated the synthesized version into Dutch. A scientific committee reached consensus on discrepancies and developed a pre-final version of the questionnaire. The field test with cognitive debriefing involved 10 patients with axSpA with different gender, age, disease duration, educational level and working status. RESULTS: The translation process of the mSQUASH was completed without major issues. The first translation needed several iterations due to small discrepancies in the wording. Back-translation was performed without difficulties, and the scientific committee agreed upon a final version of the questionnaire. Cognitive debriefing showed the Spanish questionnaire to be clear, relevant, understandable and comprehensive. The preliminary version was accepted with minor modifications. CONCLUSIONS: The resulting Spanish version of the mSQUASH showed good linguistic and face validity according to the field test, revealing potential for use in clinical practice and research. In order to conclude the cross-cultural adaptation of the mSQUASH into Spanish, the next step is the assessment of psychometric properties of the Spanish version.

In this article, we review published literature on "telerheumatology", a term describing the use of telemedicine in rheumatology. This field has received considerable recent attention through the development of efficient digital technologies, resulting in a good level of satisfaction among patients and health care professionals. In 2020, the social distancing constraints during the COVID-19 pandemic accelerated more widespread adoption worldwide. Telerheumatology is particularly suited for patients with rheumatoid arthritis who have achieved a sustained therapeutic target of remission or low disease activity. To facilitate remote consultations and meet expectations of rheumatologists and patients, international and national guidelines have recently been proposed and existing tools, such as Patient-Reported Outcomes questionnaires, have had to be digitally adapted. In addition, telerheumatology toolkits are proposed by the Arab League of Associations for Rheumatology (ArLAR), the Association of American Medical College (AAMC), and the American College of Rheumatology (ACR) for all learners, from medical students to practicing clinicians, encouraging the acquisition of telehealth skills and facilitating their integration into their routine clinical practice. The main benefits reported for this mode of health care are greater access to specialty care, flexibility, reduced rates of missed appointments, as well as improved patient engagement and autonomy. Limitations include the absence of physical examination. However, to implement telerheumatology effectively and widely in daily clinical practice, some barriers still need to be addressed. These include training of health care professionals, technological restrictions and reimbursement mechanisms. Despite the advantages of telerheumatology, it is not intended to replace face-to-face visits, but rather as a way to enhance access to care, service delivery and health care support for patients.

Antecedentes: Las medidas de resultado para la evaluación de la actividad física en pacientes con espondiloartritis axial (EspAax) son escasas. Por ello, se desarrolló y validó el modified Short QUestionnaire to Assess Health (mSQUASH), originalmente en holandés. Objetivo: Desarrollar el proceso de traducción y adaptación transcultural del mSQUASH al español, y evaluar la equivalencia de la versión traducida en pacientes con EspAax. Métodos: El mSQUASH se tradujo siguiendo el procedimiento adelante-atrás según el protocolo de Beaton. Dos traductores bilingües realizaron traducciones directas independientes del mSQUASH al español, y las versiones se armonizaron en una versión consensuada. Otro traductor volvió a traducir la versión sintetizada al holandés. Un comité científico llegó a un consenso sobre las discrepancias y elaboró una versión pre-final del cuestionario. En las entrevistas cognitivas participaron 10 pacientes con EspAax de diferente sexo, edad, duración de la enfermedad, nivel educativo y situación laboral. Resultados: El proceso de traducción del mSQUASH se completó sin problemas mayores. La primera traducción necesitó varias iteraciones debido a pequeñas discrepancias en la redacción. La traducción inversa se realizó sin dificultades y el comité científico acordó la versión final del cuestionario. La evaluación cognitiva demostró que el cuestionario en español era claro, pertinente, comprensible y completo. La versión preliminar fue aceptada con pequeñas modificaciones. Conclusiones: La versión española resultante del mSQUASH mostró una buena validez lingüística y aparente, revelando potencial para su uso en práctica clínica e investigación. Para concluir la adaptación transcultural del mSQUASH al español, el siguiente paso es la evaluación de las propiedades psicométricas de la versión española. (AU)

INTRODUCTION: This post hoc analysis of the phase 3 rheumatoid arthritis (RA) filgotinib clinical trial program assessed the effect of filgotinib on body mass index (BMI) in patients with RA and the impact of BMI on the efficacy and safety of filgotinib. METHODS: FINCH 1-3 were randomized, double-blind, active- or placebo-controlled phase 3 trials of filgotinib 100 and 200 mg in patients with RA (N = 3452). BMI assessments included the mean change from baseline in BMI and the proportion of patients whose BMI increased by incremental thresholds. Efficacy measures included American College of Rheumatology (ACR) 20/50/70 response and low disease activity/remission according to Disease Activity Score 28 using C-reactive protein. The exposure-adjusted incident rate (EAIR) of adverse events (AEs) was assessed by baseline BMI, using integrated data from the FINCH 1-4 and the phase 2 DARWIN 1-3 studies (total filgotinib exposure = 8085 patient-years). RESULTS: Mean change from baseline in BMI over time was similar across treatment arms. In most patients, BMI increased by ≤ 1 or 2 kg/m2 at both weeks 12 and 24, regardless of treatment group or baseline BMI; few patients had increases of ≥ 4 kg/m2. For most efficacy measures, filgotinib 200 mg was more efficacious than filgotinib 100 mg or active comparators or placebo across BMI subgroups. For the higher filgotinib dose, the EAIR of serious treatment-emergent AEs, venous thrombotic and embolic events, and major adverse cardiovascular events increased with increasing BMI. CONCLUSIONS: Filgotinib did not lead to substantial changes in BMI, and BMI did not appear to affect the efficacy of filgotinib. TRIAL REGISTRATION: ClinicalTrials.gov identifiers: NCT02889796, NCT02873936, NCT02886728, NCT03025308, NCT01888874, NCT01894516, NCT02065700.
Some rheumatoid arthritis treatments cause patients to gain weight or are less effective in patients with obesity than in patients without obesity. Also, obesity can make rheumatoid arthritis worse. Filgotinib is a rheumatoid arthritis treatment that was evaluated in seven randomized clinical studies (FINCH 14 and DARWIN 13). We investigated whether filgotinib causes changes in weight and whether body mass index (BMI) affects the efficacy or safety of filgotinib. We analyzed how the BMI of patients who participated in FINCH 1, 2, or 3 changed over time. Most patients had a small increase in BMI (around 12 kg/m2) after 24 weeks of filgotinib treatment. This change in BMI was not affected by patients' BMI at baseline. Baseline BMI did not impact the efficacy of filgotinib, which was assessed using standard measures of disease activity. Filgotinib was more effective than other rheumatoid arthritis treatments and placebo in all patients, regardless of BMI subgroup. Using safety data from all seven clinical studies (FINCH 14 and DARWIN 13), we found that some adverse events occurred more often in patients with obesity (a BMI of ≥ 30 kg/m2) than in those without obesity. The increased adverse events included venous thrombotic and embolic events and major adverse cardiovascular events, for which obesity is a known risk factor. These results show that filgotinib did not substantially change BMI (which increased by around 12 kg/m2 in most patients), and that baseline BMI did not affect the efficacy of filgotinib.
ABSTRACT
OBJECTIVES: To analyse the trajectories of Disease Activity Score 28 (DAS28), patient global assessment (PGA) and physician global assessment (PhGA) and to assess their predictive capabilities on difficult-to-treat rheumatoid arthritis (D2TRA) classification. METHODS: Longitudinal study of patients with rheumatoid arthritis (RA) from 2020 to 2022. Based on the D2TRA EULAR (European Alliance of Associations for Rheumatology) definition, patients were classified as D2TRA according to biological or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) failure due to inefficacy (D2TRA-inefficacy) or other reasons (D2TRA-other). Patients who did not fulfil the D2TRA criteria were classified as NoD2TRA. DAS28, PGA and PhGA scores collected every 6 months during the first 24 months of b/tsDMARD treatment were used to identify different trajectories using latent class mixed models (LCMM). RESULTS: The study population comprised 255 patients with RA, of whom 167 were NoD2TRA, 58 D2TRA-inefficacy and 30 D2TRA-other. LCMM stratified patients into two different trajectories for DAS28 and PhGA and three for PGA according to the most stable model. The most notable variation occurred during the first 6 months of treatment, thereafter remaining stable during the follow-up period. Most D2TRA-inefficacy patients fitted the trajectory, showing higher values of the studied parameters. NoD2TRA followed the trajectory with lower values, and D2TRA-other were distributed more homogeneously across all trajectories. CONCLUSIONS: The assessment of disease activity, together with patients' and physicians' perceptions, form a key element in the correct discrimination of patients who are going to develop D2TRA-inefficacy. However, identifying those patients who will be D2TRA-other remains challenging, whether by subjective or objective parameters.

BACKGROUND: Real world data on the response to the SARS-CoV-2 vaccine in patients with immunomediated diseases (IMIDs) treated with immunesuppressants is of great interest because vaccine response may be impaired. The main aim was to study the humoral and cellular immune response after SARS-CoV-2 vaccination in patients with IMIDs treated with immunosuppressants. The secondary aim was to describe the frequency of SARS-CoV-2 infections after vaccination in these patients. MATERIAL AND METHODS: This is an observational study including 86 patients with IMIDs. All patients were treated with biologic or targeted synthetic disease-modifying antirheumatic drugs [b/tsDMARDs: TNF inhibitors (TNFi), rituximab, anti-interleukin 6 receptor (anti-IL6R) or JAK inhibitors (JAKi)]. Demographic and clinical information were collected. After 4-6 weeks of 2nd and 3rd vaccine doses, humoral response was assessed using the Thermo Scientific ELiA SARS-CoV-2-Sp1 IgG Test. Also, in patients with serum SARS-CoV-2 antibody levels under 100UI/ml, cellular response was analyzed using the QuantiFERON SARS-CoV-2 Starter Pack. RESULTS: A total of 86 patients under b/tsDMARDs and 38 healthy controls were included. Most patients received TNFi (45 with TNFi, 31 with rituximab, 5 with anti-IL6R and 5 with JAKi). SARS-CoV-2 antibodies (Ab) were present in an 86% of patients with IMIDs and in 100% healthy controls (p = 0.017). However, 12 (14%) patients had undetectable SARS-CoV-2 Ab levels, all treated with rituximab. In addition, SARS-CoV-2 Ab (IU/ml) were statistically lower in patients (Mdn (IQR): 59.5 (17-163) in patients vs 625 (405-932) in controls, p < 0.001). Patients treated with rituximab had lower Ab levels than those treated with TNFi and controls (p < 0.001). The cellular response to SARS-CoV-2 vaccine was evaluated in 30 patients. Eleven patients had a positive cellular response, being more frequent in patients treated with rituximab (p = 0.03). SARS-CoV-2 infection was reported in 43% of patients and 34% of controls after vaccination. Only 6 (7%) patients required hospitalization, most of whom treated with rituximab (67%). CONCLUSION: SARS-CoV-2 antibody levels were lower in patients than in controls, especially in patients treated with rituximab. A cellular response can be detected despite having a poor humoral response. Severe infections in vaccinated patients with IMIDs are rare, and are observed mainly in patients treated with rituximab.
ABSTRACT
BACKGROUND: Rheumatic and Musculoskeletal Diseases (RMDs) substantially impact the lives of patients, with complex associations between disease severity and self-perceived health status. In this regard, the Coping with Rheumatic Stressors (CORS) questionnaire was developed to measure how patients with RMDs cope with stressors such as pain, limitations or dependency. The CORS is not currently available in Spanish, and therefore the adaptation of this instrument is needed. OBJECTIVE: First, to cross-culturally adapt the CORS into Spanish for Spain. Secondly, to test the conceptual equivalence of the translated version in patients with axial spondyloarthritis (axSpA). METHODS: A translation of the CORS into Spanish was performed adhering to the forward-backward procedure described by Beaton. Two translators produced independent forward translations of the item content, response options, and instructions of the CORS into Spanish. Both versions were harmonized in a consensual version. Another translator back-translated the synthesized version into Dutch. A scientific committee including all the translators, one methodologist and a rheumatologist, held a meeting and reached consensus on discrepancies to develop a final draft version of the Spanish CORS. Then, a field test with cognitive debriefing was conducted, involving a sample of 10 patients with axSpA. RESULTS: The translation process of the CORS was completed after the discussion of some discrepancies throughout the process. The first translation was done without major complications. Back-translation presented some discrepancies. These led to minor modifications in the wording in one response option and 15 questionnaire items. The scientific committee agreed upon a final version of the questionnaire. Cognitive debriefing, led to minor modifications; for example, three respondents indicated that one of the statements in the instructions was syntactically complex ("indique cuán a menudo usted ha llevado a cabo dicho comportamiento") which led to its adjustment. The process indicated that the final CORS Spanish questionnaire was clear and understandable to all patients. CONCLUSIONS: The Spanish version of the CORS showed good cross-cultural validity and good face validity according to the field test. Before the Spanish CORS is implemented, further validation is in progress to test the psychometric properties of the instrument in patients with axSpA.

OBJECTIVES: To analyse the influence of adipokines on attaining the clinical outcomes in patients with axial spondyloarthritis (axSpA) treated with TNF inhibitors (TNFi), and then, to investigate the association of patients' characteristics and adipokine concentrations. METHODS: This was a longitudinal study including 110 patients with axSpA who were initiated at TNFi and were followed-up for 6 months (m). Disease activity was assessed by Ankylosing Spondylitis Disease Activity Score (ASDAS) at baseline and at 6 m of treatment. Clinical outcomes at 6 m of treatment were defined as remission (ASDAS <1.3) and the attainment of low disease activity (LDA; ASDAS<2.1). Leptin and adiponectin concentrations were measured in serum samples collected at baseline and after 6 m. RESULTS: Both leptin and adiponectin were constitutively elevated in female axSpA patients. At time of TNFi initiation, leptin concentrations were higher in patients with high body mass index (overweight or obese). On the contrary, adiponectin was higher in normalweight patients. After 6 m of TNFi treatment, 24% of patients attained remission. They had significant lower leptin concentration at baseline compared with patients who did not attain remission. Furthermore, this difference remained significant after 6 m of treatment meaning that TNFi did not modify adipokine concentration. Similar results were found considering LDA as the clinical outcome, obtained in 48% of the patients. CONCLUSIONS: The present study showed that low leptin concentrations were associated with attaining clinical outcomes in axSpA patients treated with TNFi. In addition, since leptin secretion by white adipocytes is enhanced during obesity and considering that TNFi do not seem to modulate its expression, obese patients should be encouraged to decrease BMI to attain a successful therapy.
