RESUMO

Fundamento y objetivo: La arteritis de células gigantes (ACG) es la vasculitis sistémica más frecuente en adultos. En los últimos años, existe un interés creciente en evaluar la utilidad de la ecografía de arterias temporales superficiales (EATS), que permite valorar la inflamación de la pared vascular. Material y métodos: Estudio de cohorte observacional y descriptivo de 120 EATS a 60 pacientes con sospecha clínica de ACG según criterios clásicos de ACR (American College of Rheumatology). Resultados: De todos los pacientes a quienes se les realizó la EATS, el 42,3% presentó diagnóstico de ACG según los criterios de clasificación ACR. La sensibilidad y la especificidad de la ecografía en nuestra cohorte de pacientes con alta sospecha clínica fueron de 81,8 y 93,3%, respectivamente, con un VPP de 90,1% y un VPN de 87,5%. Conclusión: Los resultados avalan la ecografía de arteria temporal bilateral como una técnica útil, indolora, rápida, accesible, de alta especificidad y amplia validez diagnóstica

RESUMO

To assess the hypothesis if tocilizumab (TCZ) is effective on disease activity, and also its effect in fatigue and other clinical and psychological disease-related factors in patients with rheumatoid arthritis (RA) treated with TCZ.A 24-week, multicenter, prospective, observational study in patients with moderate to severe RA receiving TCZ after failure or intolerance to disease-modifying antirheumatic drugs or tumor necrosis factor-alpha was conducted.Of the 122 patients included, 85 were evaluable for effectiveness (85% female, 51.9 ±â€Š12.5 years, disease duration 8.7 ±â€Š7.4 years). Mean change in C-reactive protein level from baseline to week 12 was -11.2 ±â€Š4.0 (P < .001). Mean Disease Activity Index score (DAS28) decreased from 5.5 ±â€Š1.0 at baseline to 2.7 ±â€Š1.3 (P < .001) at week 24. Mean change in Functional Assessment of Chronic Illness Therapy score was -5.4 ±â€Š11.2 points at week 24. Multiple regression analysis showed that the improvement in DAS28, sleep, and depression explained 56% and 47% of fatigue variance at week 12 and 24, respectively.Tocilizumab is effective in reducing disease activity and results in a clinically significant improvement in fatigue, pain, swollen joint count, morning stiffness, sleepiness, depression, and DAS28; the last 3 were specifically identified as factors explaining fatigue variance with the use of TCZ in RA patients.

RESUMO

Background: Rheumatoid arthritis (RA) is the most frequent autoimmune disease involving the joints. Although anti-TNF therapies have proven effective in the management of RA, approximately one third of patients do not show a significant clinical response. The objective of this study was to identify new genetic variation associated with the clinical response to anti-TNF therapy in RA. Methods: We performed a sequential multi-omic analysis integrating different sources of molecular information. First, we extracted the RNA from synovial biopsies of 11 RA patients starting anti-TNF therapy to identify gene coexpression modules (GCMs) in the RA synovium. Second, we analyzed the transcriptomic association between each GCM and the clinical response to anti-TNF therapy. The clinical response was determined at week 14 using the EULAR criteria. Third, we analyzed the association between the GCMs and anti-TNF response at the genetic level. For this objective, we used genome-wide data from a cohort of 348 anti-TNF treated patients from Spain. The GCMs that were significantly associated with the anti-TNF response were then tested for validation in an independent cohort of 2,706 anti-TNF treated patients. Finally, the functional implication of the validated GCMs was evaluated via pathway and cell type epigenetic enrichment analyses. Results: A total of 149 GCMs were identified in the RA synovium. From these, 13 GCMs were found to be significantly associated with anti-TNF response (P < 0.05). At the genetic level, we detected two of the 13 GCMs to be significantly associated with the response to adalimumab (P = 0.0015) and infliximab (P = 0.021) in the Spain cohort. Using the independent cohort of RA patients, we replicated the association of the GCM associated with the response to adalimumab (P = 0.0019). The validated module was found to be significantly enriched for genes involved in the nucleotide metabolism (P = 2.41e-5) and epigenetic marks from immune cells, including CD4+ regulatory T cells (P = 0.041). Conclusions: These findings show the existence of a drug-specific genetic basis for anti-TNF response, thereby supporting treatment stratification in the search for response biomarkers in RA.

RESUMO

Objetivo: El paradigma actual en el tratamiento de la artritis reumatoide (AR) contempla el diagnóstico temprano y el uso precoz de fármacos modificadores de enfermedad (FAME) para alcanzar la remisión o baja actividad inflamatoria, lo cual, se conoce como «treat to target» (T2T). El objetivo del trabajo es desarrollar un indicador compuesto (IC) para evaluar la calidad asistencial en el manejo de los pacientes con AR atendiendo a la estrategia T2T y a otras recomendaciones generales para la atención de estos pacientes. Material y método: La construcción del IC siguió las fases: 1) selección de los criterios de calidad mediante un juicio de expertos; 2) priorización de los criterios, a partir de un Delphi con 20 expertos; 3) diseño de los indicadores de calidad, y 4) cálculo del IC ponderado. La fuente de información para el cálculo del IC son las historias clínicas de los pacientes con AR. Resultados: De los 37 criterios seleccionados, 12 necesitaron una segunda ronda Delphi. Se priorizaron 31 criterios, los cuales presentaron una mediana en relevancia y factibilidad, en las rondas Delphi, mayor o igual a 7,5, con un rango intercuartílico inferior a 3,5, y un grado de acuerdo (puntuación mayor o igual a 8) igual o superior al 80%. Conclusiones: El IC construido, consensuado y ponderado, permite evaluar la calidad asistencial de los pacientes con AR, en las Unidades de Reumatología de hospitales españoles, ofreciendo una medida resumen válida y fácilmente interpretable


Objective: The current guidelines in the treatment of rheumatoid arthritis (RA) include the early diagnosis and early use of disease modifying drugs to achieve remission or low disease activity level, known as "Treat to Target" (T2T). The objective of this study is to develop a composite indicator (CI) to evaluate the quality of care in the management of patients with RA, according to the T2T strategy and other general recommendations concerning the management of these patients. Material and method: The phases of the construction of the CI were: 1) selection of quality criteria through expert judgment; 2) prioritization of the criteria, according to relevance and feasibility, applying the Delphi methodology (two rounds) involving 20 experts; 3) design of quality indicators; and 4) calculation of the weighted CI, using the mean value in relevance and feasibility granted by the experts. The source of information for the calculation of the CI are the medical records of patients with RA. Results: Twelve criteria out of 37 required a second Delphi round. Thirty-one criteria were prioritized. These criteria presented a median in relevance and feasibility greater than or equal to 7.5, with an interquartile range of less than 3.5, and a level of agreement (score greater than or equal to 8) greater than or equal to 80%. Conclusions: The constructed CI allows us to evaluate the quality of care of patients with RA following the T2T strategy in the rheumatology units of Spanish hospitals, offering a valid and easily interpretable summary measure

RESUMO

Systemic lupus erythematosus (SLE) is an autoimmune disease associated with the polyclonal activation of B lymphocytes and the production of autoantibodies that cause immune complex-related inflammation. Immunological factors derived from platelets modulate B cell function in SLE disease. However, platelets do not only modify the immune system by soluble factors. The binding of platelets to lymphocytes can modulate immune response. Thus, we speculate that the binding of platelets to lymphocytes in SLE patients may play a role in abnormal B lymphocyte response and the pathogenesis of SLE. We observed that levels of lymphocytes with bound platelets were higher in SLE patients than in healthy donors (HD). In SLE patients, the percentage of B lymphocytes with bound platelets positively correlated with plasmatic levels of IgG, IgA, IL-10, and soluble CD40L and negatively correlated with IgM levels, though not in HD. Preswitched memory B lymphocytes were the subpopulation with more bound platelets. Lymphocytes with bound platelets from both HD and SLE patients had major levels of CD86 and BAFFR and a greater production of IL-10 than lymphocytes without bound platelets. However, only B lymphocytes with bound platelets from SLE patients had increased levels of IgG and IgA on their surface. SLE patients with a suggestive renal manifestation had the highest levels of B and T lymphocytes with bound platelets. These results suggest that the binding of platelets to lymphocytes plays a role in SLE disease and that controlling this binding may be a promising therapeutic approach.

RESUMO

OBJECTIVE: To formulate SER recommendations for the use of biological agents in primary Sjögren's syndrome (pSS). METHODS: Relevant clinical research questions were identified on the use of biological agents in pSS. The clinical questions were reformulated into 4PICO questions. A search strategy was designed and a review of the scientific evidence of studies published until May 2017 was carried out. The scientific evidence available was systematically reviewed. The overall level of scientific evidence was assessed using the SIGN evidence levels. After that, specific recommendations were made. RESULTS: Rituximab is recommended as the biological agent of choice for extraglandular manifestations refractory to conventional treatment. The use of anti-TNF agents is discouraged. The scientific evidence with belimumab and abatacept is scarce, so they should be considered only in cases refractory to rituximab. CONCLUSIONS: Rituximab is the biological agent of choice in severe extraglandular manifestations of pSS. Belimumab or abatacept may be useful in selected cases.

RESUMO

OBJECTIVE: Psoriatic arthritis (PsA) is a chronic inflammatory arthritis affecting up to 30% of patients with psoriasis (Ps). To date, most of the known risk loci for PsA are shared with Ps, and identifying disease-specific variation has proven very challenging. The objective of the present study was to identify genetic variation specific for PsA. METHODS: We performed a genome-wide association study in a cohort of 835 patients with PsA and 1558 controls from Spain. Genetic association was tested at the single marker level and at the pathway level. Meta-analysis was performed with a case-control cohort of 2847 individuals from North America. To confirm the specificity of the genetic associations with PsA, we tested the associated variation using a purely cutaneous psoriasis cohort (PsC, n=614) and a rheumatoid arthritis cohort (RA, n=1191). Using network and drug-repurposing analyses, we further investigated the potential of the PsA-specific associations to guide the development of new drugs in PsA. RESULTS: We identified a new PsA risk single-nucleotide polymorphism at B3GNT2 locus (p=1.10e-08). At the pathway level, we found 14 genetic pathways significantly associated with PsA (pFDR<0.05). From these, the glycosaminoglycan (GAG) metabolism pathway was confirmed to be disease-specific after comparing the PsA cohort with the cohorts of patients with PsC and RA. Finally, we identified candidate drug targets in the GAG metabolism pathway as well as new PsA indications for approved drugs. CONCLUSION: These findings provide insights into the biological mechanisms that are specific for PsA and could contribute to develop more effective therapies.

RESUMO

INTRODUCTION: Given the lack of standardized tools to assess tolerability from patient's perspective, we carried out the validation of a questionnaire to asses treatment tolerability for rheumatoid arthritis (RA): TOL-AR-18. METHODS: The TOL-AR-18 was validated in the cross-sectional observational study in adult patients with RA. Socio-demographic and clinical variables were collected. Patients completed the TOL-AR-18 and ARTS questionnaires and a question about their general health status. RESULTS: Data of 66 patients with a mean age (standard deviation; SD) of 56.71 (10.50) years were analyzed; 66.7% were women. Mean (SD) time to disease progression was 10.76 (8.23) years, and time from first treatment initiation was 9.24 (7.70) years. Patients did not report other adverse events rather than those included in the TOL-AR-18. The questionnaire was feasible with high internal consistency (Cronbach's α >0.90). Discriminant validity was moderate, with significant differences between patients in remission and all other, and between patients who did not report adverse events and the rest (P<.05). Convergent validity was moderate-low when correlated with the ARTS questionnaire. CONCLUSION: The TOL-AR-18 is valid for use in a clinical setting and useful as an additional tool for all professionals to manage and assess tolerability in RA.

RESUMO

Ultrasonography has been rarely used to measure musculoskeletal and joint activity in systemic lupus erythematosus (SLE). The aim of this review is to discuss the utility and reliability of this non-invasive diagnostic tool for the assessment of joint disease in SLE patients. In the last decade, several reports have highlighted the role of ultrasonography for a better evaluation of SLE-related musculoskeletal symptoms. The symptoms have also been associated with worse outcomes in SLE; therefore, it is essential to seek useful and accessible techniques for better understanding of such patients who are insufficiently assessed by standard physical examination.

RESUMO

OBJECTIVE: To draft recommendations on interleukin 6 (IL-6) blockade in rheumatoid arthritis (RA), based on best evidence and experience. METHODS: A group of 10 experts on IL-6 blockade in RA was selected. The 2 coordinators formulated 23 questions about IL-6 blockade (indications, efficacy, safety, etc.). A systematic review was conducted to answer the questions. Using this information, inclusion and exclusion criteria were established, as were the search strategies (Medline, EMBASE and the Cochrane Library were searched). Two different reviewers selected the articles. Evidence tables were created. At the same time, European League Against Rheumatism and American College of Rheumatology abstracts were evaluated. Based on this evidence, the coordinators proposed preliminary recommendations that the experts discussed and voted on in a nominal group meeting. The level of evidence and grade of recommendation were established using the Oxford Centre for Evidence Based Medicine and the level of agreement with the Delphi technique (2 rounds). Agreement was established if at least 80% of the experts voted yes (yes/no). RESULTS: The 8 preliminary recommendations were accepted after the Delphi process. They covered aspects such as the use of these therapies in monotherapy, in combination, in patients with refractory disease or intolerant patients, response evaluation, optimization and risk management. CONCLUSIONS: The manuscript aims to solve frequently asked questions and aid in decision making strategies when treating RA patients with IL-6 blockade.

RESUMO

Objetivos. Desarrollar recomendaciones sobre el uso de metrotexato (MTX) parenteral en pacientes con enfermedades reumáticas, fundamentalmente en la artritis reumatoide, basadas en la mejor evidencia y experiencia. Métodos. Se seleccionó un grupo de 21 expertos reumatólogos en el manejo de MTX. El coordinador generó 13 preguntas sobre el uso de MTX parenteral (perfiles de indicación, eficacia, seguridad, costo-eficacia y biodisponibilidad) para ser contestadas mediante una revisión sistemática de la literatura. Con base en las preguntas se definieron los criterios de inclusión y exclusión, y las estrategias de búsqueda (en Medline, EMBASE y la Cochrane Library). Tres revisores seleccionaron los artículos resultantes de la búsqueda. Se generaron tablas de evidencia. Paralelamente se evaluaron abstracts de congresos de la European League Against Rheumatism (EULAR) y del American College of Rheumatology (ACR). Con toda esta evidencia el coordinador generó 13 recomendaciones preliminares que se evaluaron, discutieron y votaron en una reunión del grupo nominal con los expertos. Para cada recomendación se estableció el nivel de evidencia y grado de recomendación, y el grado de acuerdo mediante un Delphi. Se definió acuerdo si al menos el 80% de los participantes contestaron sí a la recomendación (sí o no). Resultados. La mayoría de la evidencia proviene de la artritis reumatoide. De las 13 recomendaciones preliminares se aceptaron 11 recomendaciones sobre el uso de MTX parenteral en reumatología. Dos no se llegaron a votar y se decidió no incluirlas, pero se comentan en el texto final. Conclusiones. Este documento pretende resolver algunos interrogantes clínicos habituales y facilitar la toma de decisiones con el uso de MTX parenteral

RESUMO

En junio de 2017, la European Medicines Agency aprobó sarilumab para el tratamiento de la artritis reumatoide, un nuevo anticuerpo monoclonal (subtipo IgG1) totalmente humano, que impide la unión de la interleucina (IL) 6 a las formas soluble y unida a la membrana del receptor de la IL-6, e inhibe la señal a través de IL-6. Administrado cada 2 semanas en dosis de 200 mg (con una dosis de 150 mg cada 2 semanas para el tratamiento de anormalidades de laboratorio), tiene una afinidad por el receptor muy elevada y ha demostrado ser un fármaco eficaz y seguro en el tratamiento de la artritis reumatoide. Esta eficacia se ha demostrado en diferentes ensayos clínicos evaluados en distintos escenarios: falta de respuesta a metotrexato, intolerancia y/o fallo a antifactor de necrosis tumoral alfa y en pacientes con intolerancia a metotrexato. Su doble dosis, su doble dispositivo de administración, su mecanismo dual y su beneficio reconocido lo sitúan como una nueva alternativa potencial en el tratamiento de la artritis reumatoide


In June 2017, the EMA approved sarilumab for the treatment of rheumatoid arthritis, a new monoclonal (subtype IgG1) fully human antibody directed against the alpha subunit of the interleukin-6 receptor complex that inhibits the signal through IL-6. The drug is administered every other week at a dose of 200 mg (or a dose of 150 mg every two weeks if there are laboratory abnormalities), shows very high affinity for the receptor and has proven to be an effective and safe drug in the treatment of rheumatoid arthritis (RA). Its efficacy has been demonstrated in several clinical trials in a variety of scenarios (lack of response to MTX, intolerance and / or failure to anti-TNF). Due to its double dose, the availability of two different devices for its administration, and its dual signaling mode of action and recognised benefit, sarilumab is a new potential alternative in the treatment of RA

RESUMO

Rosai-Dorfman disease (RDD) is uncommon in daily practice, but needs to be ruled out in rheumatologic conditions to elucidate a wide differential diagnosis. Beside its typical presentation, soft tissue masses can be easily seen in our Rheumatology clinics. Ultrasonography widely extended in our specialty, could also play a role in the diagnosis, to end up with the histological confirmation of the disease.

RESUMO

Objetivo. Existen pacientes con artritis reumatoide (AR) que no responden de la forma deseada a la terapia biológica. Nuestro objetivo fue reconocer los atributos del FAME biológico (FAMEb) que podrían identificar al más adecuado en las primeras líneas de tratamiento de la AR. Métodos. Para reconocer los atributos que podrían definir el FAMEb, se realizó una búsqueda sistemática de la literatura acerca de aspectos generales, farmacología, eficacia, seguridad, administración y coste. A continuación, se realizó un proceso Delphi a 2 rondas entre un grupo de reumatólogos expertos en el manejo de la AR para determinar el grado de acuerdo con los atributos identificados, indicando el grado de importancia que se le daba a cada atributo. Se aplicaron 2 criterios para determinar la consistencia de los resultados: 1) sobre la base de la mediana y el rango intercuartílico, y 2) el cumplimiento simultáneo de media, mediana, desviación estándar, rango intercuartílico y coeficiente de variación. Se determinaron también la concordancia y la ratificación final del panel de expertos. Resultados. Ochenta y tres reumatólogos españoles completaron las 2 circulaciones del proceso Delphi. Ninguno de los 77 atributos identificados se consideró de baja importancia, 75 de los 77 (97,4%) se consideraron de alta importancia y 76 de los 77 (98,7%) fueron ratificados. Quince tuvieron el apoyo del 100% del grupo de trabajo. Conclusiones. Quince atributos tuvieron el apoyo del 100% del grupo de trabajo y podrían considerarse los que definirían el FAMEb ideal en las primeras líneas de tratamiento de la AR (AU)


Objective. To date, between 17% and 35% of patients with rheumatoid arthritis (RA) do not respond as expected to the initial biological therapy. The objective of this project is to recognize and weigh the attributes of biologic DMARD (bDMARD) to identify the most appropriate for each case, in the first lines of treatment of RA (after inadequate response to at least one synthetic DMARD or previous bDMARD). Methods. To recognize the possible attributes that could define the bDMARD, we performed a systematic search of the literature that recognized the possible attributes involving general aspects, pharmacology, efficacy, safety, management, and cost. Then a Delphi process was conducted with two rounds among a group of selected expert rheumatologists in the management of RA indicating the degree of agreement with the attributes identified in the literature. The project was completed between February and September 2015, indicating the degree of importance that was ascribed to each attribute. Two criteria were applied to determine the consistency of results: 1) based on the median and interquartile range; and 2) on the simultaneous compliance with mean, median, standard deviation, interquartile range and coefficient of variation. The agreement and final ratification of the expert panel were also determined. Results. Eighty-three Spanish rheumatologists participated and completed both rounds of the Delphi process. In no case was the importance of the 77 attributes identified considered to be low; 75 of 77 (97.4%) were considered highly important and 76 of 77 (98.7%) were ratified. Fifteen attributes had the support of 100% of the working group. Conclusions. There was a high degree of agreement concerning the selected attributes. Fifteen of them had the support of 100% of the working group and could be considered the definition of the ideal bDMARD in the first lines of RA treatment (AU)
