Valores de referencia para el 1-minute sit-to-stand test en pacientes pediátricos con artritis idiopática juvenil / Reference values for the 1-minute sit-to-stand test in pediatric patients with juvenile idiopathic arthritis

Introducción: los niños con artritis idiopática juvenil (AIJ) experimentan períodos de dolor e inmovilidad que afectan sus capacidades condicionales. Objetivos: describir los valores de referencia para el 1-minute Sit-to-Stand Test(1-STS; test de 1 minuto de sentarse y pararse) en niños con AIJ como evaluación de la capacidad aeróbico-funcional y de la fuerza muscular de los miembros inferiores (MMII).Materiales y métodos: se realizó un estudio observacional que incluyó a 15 niños con AIJ de entre 5 y 16 años. Se evaluó su rendimiento en el 1-STS. Resultados: se encontró una correlación positiva significativa entre el 1-STS y el test de la marcha de 6 minutos (r=0,56; p=0,03), como con el índice de capacidad funcional (CAPFUN) (r=0,54; p=0,03). No se observaron correlaciones significati-vas entre el Childhood Health Assessment Questionnaire (CHAQ) y el 1-STS (r=-0,21; p=0,44), tampoco con el Juvenile Arthritis Disease Activity Score (JADAS-10) (p=0,83). Conclusiones: el 1-STS parece prometedor para medir la capacidad aeróbi-co-funcional y la fuerza muscular de los miembros inferiores en niños con AIJ oligoarticular.

Telemedicine usability and satisfaction among pediatric rheumatology patients and their caregivers during COVID-19 pandemic

Background@#The 2019 coronavirus disease pandemic opened an opportunity to explore the role of telemedicine in pediatric rheumatology clinic as well as patient satisfaction with virtual visits.@*Objective@#To determine the usability and satisfaction rate of telemedicine among pediatric rheumatology patients and their caregivers.@*Method@#A cross-sectional online survey was conducted among patients and caregivers consulting via telemedicine at a pediatric rheumatology clinic of University of the Philippines – Philippine General Hospital (UP – PGH), a tertiary government hospital. Collected data included socio-demographics and the validated Telehealth Usability Questionnaire (TUQ).@*Results@#There were 39 (55.7%) patients and 31 (44.3%) primary caregivers included in the study. Across all usability factors, the response of primary caregivers did not significantly differ from those of patients. The average scores across all questions for both patients and primary caregivers were 5.96±1.19 and 6.04±1.34, respectively. This showed a high level of agreement that they were highly satisfied with telemedicine experience. Among the different usability factors, questions related to usefulness obtained the highest mean score for both patients (6.11±1.17) and primary caregivers (6.12±1.38). While the lowest mean score was observed on questions related to reliability, 5.65±1.33 for patients and 5.89±1.31 for primary caregivers.@*Conclusion@#Pediatric rheumatology patients as well as their caregivers are generally highly satisfied with telemedicine during this time of pandemic. With high patient and caregiver satisfaction, telemedicine could be an option for ambulatory patient care even after pandemic.

Pattern of prescription drugs used for patients diagnosed with systemic vasculitis / Patrón de prescripción de medicamentos utilizados en pacientes con diagnóstico de vasculitis sistémicas

ABSTRACT Introduction: Vasculitis is a heterogeneous group of diseases characterized by inflammation of the blood vessel wall, which can cause thrombosis, stenosis, or occlusion. Its pharmacological management involves corticosteroids and conventional and biological disease-modifying antirheumatic drugs. Objectives: The objective was to determine the different types of systemic vasculitis and their pharmacological treatment in a group of patients from Colombia, 2019-2020. Materials and methods: This was a cross-sectional study that identified different types of systemic vasculitis and their pharmacological management in a group of patients from a drug-dispensing database of approximately 8.5 million people. Sociodemographic, comorbidity and pharmacological variables were considered. A descriptive analysis was performed. Results: A total of 621 patients with a diagnosis of systemic vasculitis were identified. The patients had a median age of 55.0 years, and 74.4% were women. The most common vasculitis types were those limited to the skin (30.1%), granulomatosis with polyangiitis (17.6%), and necrotizing vasculopathy (10.8%). A total of 81.0% of cases received corticosteroid prescriptions, 44.0% received azathioprine, and 24.0% received methotrexate; only 1.6% were prescribed biological antirheumatic drugs. Cardiovascular diseases were the most common comorbidity. Conclusions: The pattern of prescription medications used for patients diagnosed with systemic vasculitis is heterogeneous. Much of this population has associated comorbidities, which increases the use of medications according to the current management guidelines.

RESUMEN Introducción: Las vasculitis son un grupo heterogéneo de enfermedades caracterizadas por la inflamación de la pared de los vasos sanguíneos, lo cual puede llegar a ocasionar trombosis, estenosis u oclusión. Su manejo farmacológico incluye corticoesteroides, antirreumáticos modificadores de enfermedad convencionales y biológicos. Objetivos: El objetivo de este estudio fue determinar los diferentes tipos de vasculitis sistémicas y su tratamiento farmacológico en un grupo de pacientes de Colombia. Materiales y métodos: Se trató de un estudio de corte transversal que identificó los diferentes tipos de vasculitis sistémicas y su manejo farmacológico en un grupo de pacientes, a partir de una base de datos de dispensación de medicamentos de aproximadamente 8,5 millones de personas. Se consideraron variables sociodemográficas, comorbilidades y variables farmacológicas, y se hizo un análisis descriptivo. Resultados: Se identificaron 621 pacientes con diagnóstico de vasculitis sistémicas, con una mediana de edad de 55,0 anos, el 74,4% mujeres, siendo las vasculitis más frecuentes las limitadas a la piel (30,1%), la granulomatosis con poliangeitis (17,6%) y la vasculopatía necrosante (10,8%). El 81,0% de los casos recibió corticoesteroides, el 44,0% azatioprina y el 24,0 metotrexate, mientras que solo el 1,6% tenía prescritos antirreumáticos biológicos. Las comorbilidades cardiovasculares fueron las más comunes. Conclusiones: El patrón de prescripción de medicamentos utilizados en pacientes con diagnóstico de vasculitis sistémicas es heterogéneo y acorde con las guías actuales de manejo. Gran parte de esta población cursa con comorbilidades asociadas, lo cual incrementa el uso de medicamentos.

Short communication: Differences in clinical outcomes according to the healthcare regime in Colombian patients with rheumatoid arthritis / Comunicación corta: diferencias en los desenlaces clínicos según el régimen de salud en pacientes colombianos con artritis reumatoide

ABSTRACT Introduction/Objectives: Rheumatoid arthritis (RA) is a burdensome disease from both individual and societal perspectives, in which access to a rheumatologist plays a pivotal role in disease activity and reduction of its impact. We describe preliminary results of our study aimed at exploring whether healthcare regime affiliation influences disease outcomes of Colombian patients with RA. Materials and methods: We performed a retrospective observational study of RA patients (2010 ACR/EULAR classification criteria) with at least 3 assessments in rheumatology clinics from different healthcare regimes: Contributory (CR), Subsidized (SR), a centre of clinical excellence (C3) that follows CR patients. We retrieved data from clinical charts including a follow-up period of 2 years. Results: We included one hundred and sixty patients (C3: 79 [49.4%], CR: 26 [16.2%], SR: 55 [34.2%]). Median initial age was 54 years (IQR 48-62) and most patients were women (77.8%). Of the patients, 79% had established RA and 70% had high disease activity at the beginning of the follow-up. We observed statistical differences between groups with regards to (1) median time to scheduled visits, (2) percentage of visits accomplished in scheduled time, (3) median time to real visit, (4) adherence, (5) median percentage of time in high disease activity, and (6) percentage of patients in high disease activity at the end of follow-up. The best outcomes were observed in the C3 cohort. Conclusions: Access opportunity and clinical outcomes of Colombian patients with RA appear to differ between healthcare regimes. Although systematic bias may be present due to sample size, these data imply the healthcare regime is a major determinant of disease outcomes.

RESUMEN Introducción/Objetivos: La artritis reumatoide (AR) presenta una alta carga de enfermedad tanto desde una perspectiva individual como social. La posibilidad de acceder a un reumatólogo desempeña un papel fundamental en la actividad de la enfermedad y la reducción de su impacto. Se describen los resultados preliminares de un estudio que tiene por objetivo explorar la influencia del régimen de afiliación en salud en los desenlaces de la enfermedad en pacientes colombianos con AR. Materiales y métodos: Se realizó un estudio observacional retrospectivo en pacientes colombianos con AR (criterios de clasificación ACR/EULAR 2010), con al menos 3 consultas por reumatología, en 3 servicios ambulatorios de diferentes regímenes de atención: contributivo (RC), subsidiado (RS) y un centro de cuidado clínico de excelencia (C3). Se recogieron datos de las historias clínicas, incluyendo un periodo de seguimiento de 2 años. Resultados: Se incluyó un total de 160 pacientes (C3: 79 [49,4%], RC: 26 [16,2%], RS: 55 [34,2%]). La mediana de la edad inicial fue de 54 años (RIC 48-62) y la mayoría fueron mujeres (77,8%). El 79% de los pacientes tenía AR establecida y el 70% presentaba una alta actividad de la enfermedad al inicio del seguimiento. Se encontraron diferencias estadísticas entre los grupos en: 1) la mediana del tiempo programado para la siguiente consulta; 2) el porcentaje de las consultas cumplidas en el tiempo previsto; 3) la mediana del tiempo real en consulta; 4) la mediana de la adherencia a la toma de laboratorios; 5) la mediana del porcentaje de tiempo durante el seguimiento en alta actividad, y 6) el porcentaje de pacientes con alta actividad al final del seguimiento. Los mejores desenlaces se observaron en el grupo C3. Conclusiones: La oportunidad de acceso y los desenlaces clínicos de pacientes colombianos con AR parecen diferir según el régimen de afiliación en salud. Aunque puede existir un sesgo sistemático debido al tamaño de la muestra, estos datos apuntan a que el régimen de afiliación en salud es un determinante mayor en los desenlaces de la enfermedad.

Current status of musculoskeletal ultrasound in Colombian rheumatology

Introduction: Ultrasound is very useful in the management of rheumatological pathology today. Despite this, in Colombia, progress towards its implementation is limited and entails great difficulties. This deficit is also related to the difficulties in training new human talent. In Colombia, there is no study that identifies the current status of ultrasound among rheumatologists in the country. Methods: This is a descriptive cross-sectional study where medical specialists in Rheumatology practising in Colombia were surveyed through an online form. They were asked about general aspects and for their opinion regarding ultrasound in rheumatology and, if they practiced it, they were asked about specific aspects of its application in clinical practice. Additionally, questions were asked of the rheumatologists who are part of the specialist training processes in the country. Closed multiple-choice or Likert scale assessment questions were presented as required. The main objective was to describe the current use and opinion of musculoskeletal ultrasound in Colombian rheumatologists, as well as the limitations for its implementation. Frequency measurements were performed of the categorical variables of nominal type and ordinal type. The intention was to survey all rheumatologists in the country, who according to Colombian Society of Rheumatology data for the end of 2019 totalled 186. Results: Taking into account the number of rheumatologists of the Colombian Association of Rheumatology (Asoreuma) for 2019 totalling 186, a participation of 139 specialists (74.7%) was obtained, of which 22 of the respondents performed ultrasound in their daily practice (15.8%) the majority in this group being trained in Colombian territory (80.6%). Of the 139 respondents, 64.7% have received some type of training in ultrasound, generally pre-congress courses (22.5%), EULAR courses (16.7%) and training included in their residency curriculum outside the rheumatology service (9.8%). The acceptance of ultrasound is high among rheumatologists practicing in Colombia, 75.5% consider it important or very important and 84.9% indicated that for a comprehensive rheumatology service it is important or very important to have ultrasound. From the responses, however, they consider that its use could change their behaviour frequently, and very frequently in less than half of the cases at 46.7%. Regarding the opinion on the use of ultrasound in specific pathologies, rheumatoid arthritis (77.7%) and crystal arthropathies (72.7%) were considered the highest and most important, as well as in the performance of procedures at 87%. For decision-making in the inflammatory pathology study, 60.4% would consider performing ultrasound compared to 28.8% who responded MRI. Regarding the limitations for implementation, the lack of training in the country (25.6%), followed by the lack of resources to procure equipment (17.9%) and ignorance and lack of interest on the part of the health entities (17.1%) were the most recognized. Conclusion: Musculoskeletal ultrasound is only practiced by a minority of rheumatologists practicing in Colombia, even though the majority consider it important. Its importance lies in its use to treat patients with rheumatoid arthritis, crystal arthropathies and psoriatic arthropathy, as well as for the performance of procedures. More than half of the rheumatologists have received some type of training in ultrasound, usually very few hours' education and without practical or informal training, this being the main problem for its implementation.

Introducción: En la actualidad, la ecografía es de gran utilidad en el manejo de la patología reumatológica. A pesar de esto, en Colombia, los avances para su implementación son escasos y han enfrentado grandes dificultades. Este déficit también se encuentra relacionado con las complicaciones para la formación del nuevo talento humano. En Colombia no se dispone de ningún estudio en el que se identifique el estado actual de la ecografía entre los reumatólogos del país. Métodos: Se trata de un estudio descriptivo de carácter transversal en el cual se encuestó, por medio de un formulario on-line, a médicos especialistas en reumatología que hacen su práctica en el territorio colombiano. Se les preguntó acerca de los aspectos generales y su opinión sobre la ecografía en la reumatología, si la practicaban, como también en torno a los aspectos específicos de su aplicación en la práctica clínica. De manera adicional, se formularon preguntas dirigidas a aquellos reumatólogos que hacen parte de los procesos de capacitación de especialistas en el país; se presentaron preguntas cerradas de opción múltiple o de valoración por escala de Likert según se requirió. El objetivo principal fue describir el uso y la opinión actual sobre la ecografía musculoesquelética en reumatólogos colombianos, así como las limitantes para su implementación. A las variables categóricas de tipo nominal y de tipo ordinal se les hicieron medidas de frecuencia. Se pretendía encuestar a la totalidad de los reumatólogos en el país, los cuales, según información de la Asociación Colombiana de Reumatología (Asoreuma) de finales del 2019, eran 186. Resultados: De acuerdo con el número de reumatólogos proporcionado por la Asoreuma, de 186 especialistas en el año 2019, se obtuvo una participación de 139 de estos (74,7%), de los cuales 22 realizaban ecografía en su práctica diaria (15,8%), siendo este grupo en su mayoría formado en Colombia (80,6%). De los 139 encuestados, el 64,7% había recibido algún tipo de estudios en ecografía, generalmente cursos precongreso (22,5%), cursos de la Liga Europea Contra el Reumatismo (EULAR) (16,7%) y formación incluida en el pensum de su residencia fuera del servicio de reumatología (9,8%). La aceptación de la ecografía es alta entre los reumatólogos que ejercen en Colombia, el 75,5% la consideraron importante o muy importante. Asimismo, el 84,9% indicó que para un servicio de reumatología integral es importante o muy importante contar con ecografía. Sin embargo, los encuestados consideraron que su uso podría llegar a cambiar su conducta de manera frecuente, y muy frecuentemente en menos de la mitad de los casos (46,7%). Con respecto a la opinión sobre el uso de la ecografía en patologías específicas, se consideró con importancia y mucha importancia en artritis reumatoide (77,7%) y artropatías por cristales (72,7%), que fueron las más altas, así como para la realizaron de procedimientos (87%). Para la toma de decisiones en estudio de patología inflamatoria, el 60,4% consideraría realizar ecografía, comparado con 28,8% que se inclina por la resonancia. En relación con las limitaciones para la implementación, la falta de entrenamiento en el país (25,6%), seguida de la carencia de recursos para la consecución del equipo (17,9%) y el desconocimiento y la falta de interés por parte de los entes de salud (17,1%) fueron las más reconocidas. Conclusiones: La ecografía musculoesquelética solamente es practicada por una minoría de los reumatólogos que ejercen en Colombia, a pesar de que la mayoría la considera importante. Su relevancia radica en su uso para tratar a los pacientes con artritis reumatoide, artropatías por cristales y por artropatía psoriásica, así como para la realización de procedimientos. Más de la mitad de los reumatólogos ha recibido algún tipo de formación en ecografía, la mayoría de las veces educación de muy pocas horas o sin entrenamiento práctico, o no formal, lo cual constituye el principal problema para su implementación.

Acercamiento teórico al uso de la imagenología en el diagnóstico temprano de la artritis reumatoide / Theoretical approach to the use of imaging in the early diagnosis of rheumatoid arthritis

La artritis reumatoide es una enfermedad progresiva, con manifestaciones clásicas y tempranas como es la afectación de las articulaciones pequeñas de las manos y los tobillos. Se realizó una revisión bibliográfica de los documentos publicados entre 2017 y 2022. Se realizó una lectura preliminar de 37 artículos que cumplían con los criterios de inclusión, y finalmente se seleccionaron 23 artículos, de los cuales se tomó el contenido de mayor importancia. La ecografía es una técnica fiable y más sensible que la exploración clínica en el estudio de la enfermedad músculo-esquelética, pues permite una exploración multiplanar y dinámica, lo que resulta en un diagnóstico más exacto. La técnica Doppler constituye un complemento útil en el seguimiento de estos pacientes. Esta enfermedad es recurrente en las consultas de Reumatología, por tanto, en su valoración inicial, la utilidad de los medios diagnósticos, especialmente la ecografía, tiene gran importancia.

Rheumatoid arthritis is a progressive disease, with classic and early manifestations such as involvement of the small joints of the hands and ankles. We conducted a bibliographic review of the documents published between 2017 and 2022. A preliminary reading of 37 articles that met the inclusion criteria was carried out, and 23 articles were finally selected, from which the most important content was taken. Ultrasound is a more sensitive and reliable technique than clinical examination for the study of musculoskeletal disease, since it allows a multiplanar and dynamic examination, which results in a more accurate diagnosis. Doppler technique is a useful complement in the follow-up of these patients. This disease is recurrent in Rheumatology consultations, that's why in its initial assessment, the usefulness of diagnostic means, especially ultrasound, is of great importance.

Practice of network platform teaching in standardized residency training of rheumatology and immunology / 中华医学教育探索杂志

This article intends to explore the application and implementation effect of network platform teaching in the standardized residency training of rheumatology and immunology. Through the implementation of online platform teaching (micro-class, online PBL teaching, and air class) for the training residents rotating in the rheumatology and immunology department, the questionnaire survey was carried out. The results showed that the satisfaction of the residents with the online platform teaching reached 96.88% (31/32), and more than 90.00% of the residents believed that their self-learning ability and clinical thinking ability have been improved, and their learning initiative and enthusiasm have also been improved, which deserves further promotion.

Application of case-based learning combined with online teaching in standardized residency training of rheumatology and immunology / 中华医学教育探索杂志

Objective:To investigate the effectiveness of case-based learning (CBL) combined with online teaching in standardized residency training of rheumatology and immunology.Methods:A total of 78 individuals who participated in standardized residency training in Department of Rheumatology and Immunology in our hospital from June 2019 to August 2020 were included and divided into observation group and control group. The individuals in the control group received traditional teaching, and those in the observation group received CBL combined with online teaching. The physicians receiving standardized residency training were evaluated by theoretical examination, clinical operation skill assessment, and instructor rating, and the degree of satisfaction with teaching, degree of satisfaction with teaching methods, and classroom learning atmosphere were also evaluated.Results:The observation group had a theoretical examination score of (94.10±2.01) and a clinical operation skill assessment score of (90.44±1.57), which were significantly higher than those of the control group ( P<0.05), and the observation group had a significantly better instructor rating (89.36±1.33) than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher degree of satisfaction with teaching (3.79±0.41), degree of satisfaction with teaching methods (3.92±0.27), and evaluation of classroom learning atmosphere (3.90±0.31) ( P<0.05).

Lúpus eritematoso sistêmico juvenil: manifestações clínicas, diagnóstico e tratamento / Juvenile systemic lupus erythematosus: clinical manifestations, diagnosis and treatment

Introdução: Lúpus eritematoso sistêmico juvenil é doença autoimune que se inicia em crianças e jovens com menos de 18 anos. Em comparação com a forma em adultos, ele geralmente apresenta maior morbidade, altas taxas de nefrite lúpica, manifestações reumatológicas e dermatológicas e envolvimento de mucosas. Objetivo: Revisão narrativa envolvendo alguns dos principais aspectos que concernem na doença. Métodos: Busca ativa no PubMed e Scielo, com textos em inglês e português entre 2016 e 2022, utilizando os seguintes descritores: lupus, pediatric, childhood, diagnosis. Foram eliminados artigos que não abordavam a população pediátrica ficando selecionados 12 artigos. Foram focados os aspectos gerais da doença, métodos diagnósticos, diagnósticos diferenciais, investigação laboratorial, manifestações clínicas e tratamento. Conclusão: Lúpus é doença que acomete tanto a população pediátrica quanto a adulta, mas há necessidade de mais estudos em crianças para o melhor entendimento das sutilezas que envolvem a doença em questão. Diante disso, é fundamental que os protocolos tanto de diagnóstico e tratamento, que hoje estão vigentes, sejam melhor entendidos e que mais estudos sejam realizados para aprimorar o manejo desses pacientes.

Introduction: Juvenile systemic lupus erythematosus is an autoimmune disease that begins in children and younger than 18 years. Compared with the disease in the adult, it usually has a higher morbidity, with high rates of lupus nephritis, rheumatologic and dermatologic manifestations, and mucosal involvement. Objective: To carry out a bibliographic review involving some of the main aspects concerning the disease. Methods: The research was carried out using articles in the PubMed and Scielo databases, with texts in English and Portuguese between 2016 and 2022. The search was carried out using the descriptors: lupus, pediatric, childhood, diagnosis. Articles that did not address the pediatric population were excluded. Thus, 12 articles were selected. Searched topics were: general aspects, diagnostic methods, differential diagnoses, laboratory investigation, clinical manifestations and treatment. Conclusion: Lupus is a disease that affects both the pediatric and adult populations, but there is a need for further studies in children to better understand the subtleties surrounding the disease in question. In view of this, it is essential that the protocols for both diagnosis and treatment, which are in force today, be better understood and more studies must be carried out to improve the management of these patients.

Arteritis de Takayasu como hallazgo incidental en un paciente con enfermedad celiaca: la importancia de la tomografía computarizada por emisión de positrones / Takayasu's arteritis as an incidental finding in a patient with celiac disease: the importance of positron emission computed tomography

Resumen Introducción: La arteritis de Takayasu es una vasculitis de grandes vasos que afecta a las arterias elásticas de gran calibre, fundamentalmente la aorta y sus ramas principales. Ocurre frecuentemente en mujeres entre los 20-30 años, por lo que es muy infrecuente en la edad pediátrica. Caso clínico: Se presenta el caso de una paciente de 15 años en seguimiento desde los 9 años por enfermedad celiaca. A los 13 años se detectó anemia de trastornos crónicos, elevación de proteína C reactiva y velocidad de sedimentación globular. La paciente permaneció en todo momento asintomática. Tras descartar otros procesos, se solicitó tomografía computarizada por emisión de positrones (PET-TC), donde se detectaron lesiones compatibles con vasculitis de grandes vasos. La valoración por Cardiología evidenció un aneurisma en coronaria derecha. Se realizó angio-TC, que sugirió arteritis de Takayasu tipo III. Conclusiones: Es frecuente un retraso en el diagnóstico de la arteritis de Takayasu en los pacientes pediátricos. En este caso se encontraron lesiones de la fase II sin la presencia de síntomas correspondientes a la fase I. El PET-TC permitió el diagnóstico de vasculitis, clave para el diagnóstico de la paciente.

Abstract Background: Takayasu arteritis is a large-vessel vasculitis which affects large-caliber elastic arteries, primarily the aorta and its main branches. It mainly affects women between 20-30 years, so it is rare in children. Case report: We describe the case of a 15-year-old female who was followed up since she was 9 years old due to celiac disease. At the age of 13, anaemia of chronic disorders associated to elevated C-reactive protein and erythrocyte sedimentation were detected. The patient remained asymptomatic. After excluding other diseases, we requested a positron emission computed tomography (PET-CT); lesions compatible with large-vessel vasculitis were detected. Cardiology evaluation showed an aneurysm in the right coronary artery. Angio-CT suggested Takayasu type III arteritis. Conclusions: The delay in the diagnosis of Takayasu arteritis in pediatric patients is quite common. In this case, we have found phase II lesions, with no previous phase I symptoms. However, PET-CT allowed the diagnosis of vasculitis, key to the diagnosis of the patient.

Compared efficacy of rituximab, abatacept, and tocilizumab in patients with rheumatoid arthritis refractory to methotrexate or TNF inhibitors agents: a systematic review and network meta-analysis

Abstract Background Our aim was to compare the efficacy of rituximab, tocilizumab, and abatacept in individuals with rheumatoid arthritis (RA) refractory to treatments with MTX or TNFi agents. Methods We searched 6 databases until January 2023 for phase 2-4 RCTs evaluating patients with RA refractory to MTX or TNFi therapy treated with rituximab, abatacept, and tocilizumab (intervention arm) compared to controls. Study data were independently assessed by two investigators. The primary outcome was considered as achieving ACR70 response. Results The meta-analysis included 19 RCTs, with 7,835 patients and a mean study duration of 1.2 years. Hazard ratios for achieving an ACR70 response at six months were not different among the bDMARDs, however, we found high heterogeneity. Three factors showing a critical imbalance among the bDMARD classes were identified: baseline HAQ score, study duration, and frequency of TNFi treatment in control arm. Multivariate meta-regression adjusted to these three factors were conducted for the relative risk (RR) for ACR70. Thus, heterogeneity was attenuated (I2 = 24%) and the explanatory power of the model increased (R2 = 85%). In this model, rituximab did not modify the chance of achieving an ACR70 response compared to abatacept (RR = 1.773, 95%CI 0.113-10.21, p = 0.765). In contrast, abatacept was associated with RR = 2.217 (95%CI 1.554-3.161, p < 0.001) for ACR70 compared to tocilizumab. Conclusion We found high heterogeneity among studies comparing rituximab, abatacept, and tocilizumab. On multivariate metaregressions, if the conditions of the RCTs were similar, we estimate that abatacept could increase the chance of reaching an ACR70 response by 2.2-fold compared to tocilizumab. Key messages Abatacept could increase the chance of reaching an ACR70 response by 2.2-fold compared to tocilizumab.

Do it fast! Early access to specialized care improved long-term outcomes in rheumatoid arthritis: data from the REAL multicenter observational study

Abstract Background Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. Methods Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed "early" when the rheumatologist was the first or second physician consulted after symptoms onset, and "late" when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. Results We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6-36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: −0.25 [−0.46, −0.04] and − 0.196 [−0.306, −0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. Conclusions Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

Brazilian society of rheumatology methodological guide for the development of evidence-based clinical guidelines in rheumatology

Abstract Clinical practice guidelines (CPG) are developed to align standards of health care around the world, aiming to reduce the incidence of misconducts and enabling more effective use of health resources. Considering the complexity, cost, and time involved in formulating CPG, strategies should be used to facilitate and guide authors through each step of this process. The main objective of this document is to present a methodological guide prepared by the Epidemiology Committee of the Brazilian Society of Rheumatology for the elaboration of CPG in rheumatology. Through an extensive review of the literature, this study compiles the main practical recommendations regarding the following steps of CPG drafting: distribution of working groups, development of the research question, search, identification and selection of relevant studies, evidence synthesis and quality assessment of the body of evidence, the Delphi methodology for consensus achievement, presentation and dissemination ofthe recommendations, CPG quality assessment and updating. This methodological guide serves as an important tool for rheumatologists to develop reliable and high-quality CPG, standardizing clinical practices worldwide.

Introdução: As espondiloartrites são doenças musculoesqueléticas crônicas que podem ter envolvimento axial, periférico ou misto. Devido ao grande comprometimento físico esta doença causa importante redução da qualidade de vida, mas não se sabe se isto acontece de igual maneira nas 3 formas. Objetivo: Estudar a associação entre qualidade de vida e formas de espondiloartrites. Método: Coletaram-se dados acerca de epidemiologia, perfil clínico, comorbidades e de qualidade de vida (através do SF-12 ou Short Form Health Survey­12 questions). Resultados: Incluíram-se 120 indivíduos: 60 EpA e 60 controles. O SF-12 físico tinha mediana de 38,05 para espondiloartrites e 55,1 para controle (p<0,0001). No quesito mental as medianas foram de 42,1 e 50,1 com p=0,04. Não foi possível demonstrar diferenças nos subgrupos de espondiloartrites, tanto no aspecto físico como mental (p=0,33 e 0,30 respectivamente). Conclusão: Existem diferenças significativas na qualidade de vida entre espondiloartrites e controles, mas não entre os subgrupos das espondiloartrites.

Introduction: Spondyloarthritis are chronic musculoskeletal diseases divided as axial, peripherical and mixed diseases. Due to a great physical involvement, it reduces patients' quality of life, but it is unknown how the 3 forms of the disease behave in such context. Objective: To study the quality of life association with spondyloarthritis forms. Methods: Data collection included: epidemiologic data, clinical profile, and quality of life data evaluated through the SF-12 (Short Form Health Survey­12 questions). Results: About 120 individuals were included: 60 spondyloarthritis and 60 controls. The physical SF-12 showed median of 38.05 for spondyloarthritis and 55.1 for controls (p<0.0001). The medians in mental SF-12 were 42.1 and 50.1 with p= 0.04. No differences in quality of life in the spondyloarthritis subgroups could be detected (with p=0.33 and 0.30 for physical and mental aspects). Conclusion: There was a significant difference in quality of life between spondyloarthritis sample and controls but not among the spondyloarthritis subgroups.
