Wangbi Tablets are widely used in the treatment of rheumatoid arthritis, knee osteoarthritis and other diseases at pre-sent. Long-term clinical application and research have shown that this drug has a good effect in reducing the pain of related diseases and improving symptoms. Due to the lack of guidance in the instructions and currently no relevant norms to guide the clinical application of Wangbi Tablets, in order to further improve clinicians' understanding of the drug and fully tap the clinical advantages of the drug, the Professional Committee of Orthopedics and Traumatology Drug Research of China Association of Chinese Medicine organized experts in the fields of rheumatism, orthopedics, pharmacy and methodology in Chinese and western medicine to develop expert consensus on Chinese patent medicines in accordance with the relevant requirements of the consensus methodology. Based on full consideration of clinical research evidence and expert experience, the clinical issues were summarized in the consensus, and for those clinical problems supported by evidences, the internationally recognized recommendation evaluation and formulation method GRADE was used to evaluate the evidence and form recommendations; for those clinical issues not supported by evidences, a consensus was reached through the nominal group method to form consensus recommendations. The consensus adopted a concise and clear format to form re-commendations or reach consensus suggestions on the medication regimen, medication characteristics, intervention timing, usage and dosage, course of use and safety issues for the treatment of rheumatoid arthritis and knee osteoarthritis with Wangbi Tablets. It is suggested that its application will better improve the efficacy of Wangbi Tablets in the treatment of rheumatoid arthritis and knee osteoarthritis, at the same time provide a reference for clinicians to use Wangbi Tablets in a standardized, reasonable and safe manner.

During the pathogensis of rheumatoid arthritis (RA), activated RA fibroblast-like synoviocytes (RA-FLSs) combines similar proliferative features as tumor and inflammatory features as osteoarthritis, which eventually leads to joint erosion. Therefore, it is imperative to research and develop new compounds, which can effectively inhibit abnormal activation of RA-FLSs and retard RA progression. Neohesperidin (Neo) is a major active component of flavonoid compounds with anti-inflammation and anti-oxidant properties. In this study, the anti-inflammation, anti-migration, anti-invasion, anti-oxidant and apoptosis-induced effects of Neo on RA-FLSs were explored to investigate the underlying mechanism. The results suggested that Neo decreased the levels of interleukin IL-1β, IL-6, IL-8, TNF-α, MMP-3, MMP-9 and MMP-13 in FLSs. Moreover, Neo blocked the activation of the MAPK signaling pathway. Furthermore, treatment with Neo induced the apoptosis of FLSs, and inhibited the migration of FLSs. It was also found that Neo reduced the accumulation of reactive oxygen species (ROS) induced by TNF-α. Taken together, our results highlighted that Neo may act as a potential and promising therapeutic drug for the management of RA.

To systemically evaluate the efficacy and safety of sinomenine combined with methotrexate(SIN+MTX) in the treatment of rheumatoid arthritis(RA). Literature databases of Wanfang, CNKI, VIP, SinoMed, PubMed, Cochrane Library and Web of Science were retrieved comprehensively for relevant clinical trials. The literature retrieval time was from database establishment to February 4, 2020. The quality of literatures was assessed by the Cochrane Evaluation Handbook 5.1.0, and qualified literature was reviewed and analyzed by using the RevMan 5.3 statistical software. Twenty randomized controlled trials met the inclusion criteria, and were enrolled in the Meta-analysis. The results showed that SIN+MTX remarkably reduced DAS28(MD=-0.85, 95%CI[-1.03,-0.67], P<0.000 01), and improved total efficiency(P<0.000 01). SIN+MTX could inhibit swollen joint count(MD=-1.19, 95%CI[-1.75,-0.63], P<0.000 1), tender joint count(MD=-1.58, 95%CI[-2.89,-0.28], P=0.02) and reduce morning stiffness time(MD=-8.44, 95%CI[-11.82,-5.07], P<0.000 01) compared with control group. The results showed that SIN+MTX was equal to control group in grip strength(SMD=0.20,95%CI[-1.11,1.51],P=0.77). SIN+MTX remarkably alleviated the erythrocyte sedimentation rate(MD=-9.87, 95%CI[-14.52,-5.22], P<0.000 1), C-reactive protein(SMD=-0.30, 95%CI[-0.51,-0.09], P=0.005), and rheumatoid factor(MD=-11.23,95%CI[-13.81,-8.65],P<0.000 01). The frequency of adverse reactions were reduced compared with that in the control group(P<0.000 01). Current clinical studies demonstrate that the efficacy and safety of SIN+MTX in the treatment of RA were superior to control group. However, due to the low quality and quantity of the included studies, high-quality randomized controlled trials are necessary to support the clinical evidences.

BACKGROUND@#Disease activity indices (DAIs) including disease activity score 28 (DAS28), simplified disease activity index (SDAI), and clinical disease activity index (CDAI) have been widely used in clinical practice and research studies of rheumatoid arthritis (RA). The objective of our study was to evaluate the correlation and concordance among different DAIs in Chinese patients with RA.@*METHODS@#A cross-sectional study, including patients enrolled in the Chinese registry of rheumatoid arthritis from November 2016 to August 2018, was conducted. The correlations were evaluated using Spearman correlation coefficient and concordance with Bland-Altman plots, quadratic weighted kappa, and discordance rates in the crosstab. For other indices, the optimal cutoff points corresponding to SDAI remission were explored through receiver operating characteristic curve analysis.@*RESULTS@#A total of 30,501 patients were included, of whom 80.46% were women. Most individuals were with moderate disease activity or high disease activity. High correlations among DAS28-erythrocyte sedimentation rate (ESR) and DAS28-C-reactive protein (CRP), SDAI and CDAI were observed. Similarly, the weighted kappa value among the indices was high. In Bland-Altman plots, a positive difference between DAS28-ESR and DAS28-CRP was observed, with an absolute difference of >1.2 in 3079 (10.09%) patients. In crosstab, approximately 30% of the patients were classified into different groups. Concordance values between SDAI remission and the optimal cutoff points of DAS28-ESR, DAS28-CRP, and CDAI were 3.06, 2.37, and 3.20, respectively.@*CONCLUSIONS@#Although DAIs had high correlations and weighted kappa values, the discordance between DAIs was significant in Chinese patients with RA. The four DAIs are not interchangeable.

BACKGROUND@#Clinical observational studies revealed that 99Tc-methylene diphosphonate (99Tc-MDP) could reduce joint pain and swollenness in rheumatoid arthritis (RA) patients. This multicenter, randomized, double-blind, double-dummy study aimed to evaluate the effects of 99Tc-MDP plus methotrexate (MTX) vs. MTX alone or 99Tc-MDP alone on disease activity and structural damage in MTX-naïve Chinese patients with moderate to severe RA.@*METHODS@#Eligible patients with moderate to severely active RA were randomized to receive 99Tc-MDP plus MTX (n = 59) vs. MTX (n = 59) alone or 99Tc-MDP (n = 59) alone for 48 weeks from six study sites across four provinces in China. The primary outcomes were the American College of Rheumatology 20% improvement (ACR20) response rates at week 24 and changes in modified total Sharp score at week 48.@*RESULTS@#At week 24, the proportion of participants achieving ACR20 was significantly higher in the MTX + 99Tc-MDP combination group (69.5%) than that in the MTX group (50.8%) or 99Tc-MDP group (47.5%) (P = 0.03 for MTX + 99Tc-MDP vs. MTX, and MTX + 99Tc-MDP vs.99Tc-MDP, respectively). The participants in the MTX + 99Tc-MDP group and the 99Tc-MDP group had significantly less important radiographic progression than the participants in the MTX group over the 48 weeks (MTX + 99Tc-MDP vs. MTX: P = 0.03, 99Tc-MDP vs. MTX: P = 0.03, respectively). There was no significant difference in terms of adverse events (AEs) among the groups. No serious AEs were observed.@*CONCLUSIONS@#This study demonstrated that the combination of 99Tc-MDP with MTX inhibited structural damage and improved disease activity in RA patients compared with MTX and 99Tc-MDP monotherapies, without increasing the rate of AEs. Additional clinical studies of 99Tc-MDP therapy in patients with RA are warranted.@*TRIAL, ChiCTR-IPR-14005684;

Rheumatoid arthritis(RA) is an autoimmune disease involving multiple joints bilaterally with symmetrical polyarthritis as the main symptom. The high disability rate of this disease seriously affects the quality of life of patients and even threatens their lives. The establishment of a good animal model is of great significance for the diagnosis and clinical prevention of RA. Based on the clinical characteristics of RA in traditional Chinese and Western medicine, the common animal models of RA were summarized, including drug-induced, gene-related, and syndrome and disease combined models. Joint swelling, pain, redness, nodules, and joint deformity are the main criteria for model evaluation, which have certain differences from the clinical diagnostic criteria of RA. From the perspective of syndrome differentiation, the animal model combining syndrome and disease only simulates the syndrome of traditional Chinese medicine and has no direct causal relationship with the formation of RA. In this paper, we analyzed the advantages and disadvantages of animal models of RA and the coincidence degree of the models with the clinical characteristics and then put forward the corresponding recommendations for the evaluation and improvement of these models, aiming to make the animal models of RA closer to the clinical symptoms and play an important role in the clinical diagnosis and treatment of RA.

El diagnóstico y el tratamiento de la artritis reumatoide temprana en el curso de la enfermedad proporcionan alivio de los síntomas y también previene el daño estructural a largo plazo y el deterioro funcional, con una mejora concomitante en la calidad de vida. El propósito de este estudio es exponer algunos enfoques de la artritis reumatoide en cuanto al tratamiento y comportamiento de la actividad de la enfermedad. El reconocimiento de los pacientes de que su enfermedad progresa rápidamente es fundamental para identificar candidatos en los cuales la terapia intensiva puede tener el mayor impacto, en términos de prevenir la progresión de la enfermedad. Los datos acumulados muestran que las estrategias de tratamiento intensivo con agentes biológicos, especialmente los inhibidores del factor de necrosis tumoral, son más eficaces que la monoterapia secuencial o la terapia de combinación progresiva. Estos muestran una eficacia sustancial en combinación con el metotrexato, ya que proporcionan beneficios y mejoras rápidas y sustanciales a los pacientes(AU)

Abstract Background: Methotrexate (MTX) intolerance is frequent, and its early identification may impact treatment, leading to timely changes in medication that may promote patient compliance and better control of rheumatoid arthritis (RA). The objective of this study was to identify the frequency of, and risk factors for, MTX intolerance using the Brazilian Portuguese version of the Methotrexate Intolerance Severity Score (MISS) questionnaire in patients with RA. Methods: This cross-sectional study was performed between April 2018 and April 2019 and enrolled patients with RA in regular use of oral or subcutaneous MTX for at least 3 months. Patients were invited to answer the Brazilian Portuguese version of the MISS questionnaire, and MTX intolerance was defined by a score ≥ 6 points. Age, sex, disease duration, time of MTX use, dose, route of administration, concomitant medications, comorbidities, smoking, and Disease Activity Score for 28joint (DAS28) data were collected from institutional medical records. Results: Among 120 patients, 103 (85.8%) were female, the mean age was 61 (±12.5) years, the mean duration of disease was 16 (±10.3) years, and the average duration of MTX use was 7 (±5.5) years. The frequency of MTX intolerance was 21.6%. The most frequent symptoms reported after the use of MTX were nausea (92.3%), abdominal pain (46.1%), and vomiting (30.7%). Behavioral symptoms occurred in 96.1% of patients with MTX intolerance, the most frequent being restlessness and irritability. Patients who used corticosteroids were more likely to develop MTX intolerance than those not using corticosteroids (odds ratio = 2.73; 95% confidence interval, 1.06 to 7.06; p = 0.038). Conversely, increasing age showed marginally significant association with decreased risk of MTX intolerance (p = 0.059). Conclusions: The use of the MISS questionnaire disclosed high frequencies of anticipatory, associative, and behavioral symptoms in MTX-intolerant patients, and the use of corticosteroid increases the risk of MTX intolerance. We suggest that the MISS questionnaire be used routinely in clinical practice.(AU)

Abstract Background: Last decades witnessed great technological advances in rheumatoid arthritis (RA) management, but their implementation in clinical practice might prove difficult. Despite the efficacy demonstrated in controlled trials this information needs to be confirmed by real life data. This study assessed real-life treatment among RA patients. Methods: REAL study included Brazilian RA patients from eleven centers. Interview and medical records were performed. Continuous variables were compared using Student's t or Mann-Whitney and categorical variables were assessed with chi-square or Fisher's exact tests. Results: 1115 patients were included, women 89.5%. Median age 56.6 years, disease duration 152.5 months; 78.7% were rheumatoid fator positive; 55.2% had erosive disease; DAS28 (disease activity index-28 joints) = 3.5, HAQ (health assessment questionnaire) =0.875. The median duration of symptoms until the start of first DMARD was 12 months. A total of 529 (47.2%) patients used corticosteroids; 1022 (90.8%) were on conventional synthetic (cs) DMARDs and 406 (36.1%) on biological (b) DMARDs. Methotrexate (MTX) was the most frequent csDMARD: 748 (66.5%) patients, followed by leflunomide (LFN), used by 381 (33.9%) of patients. MTX was associated to LFN in 142 (12.6%) patients. Only five (0.4%) patients used triple therapy (MTX + hydroxychloroquine + sulfasalazine) or sulfasalazine in monotherapy. Conclusions: Despite advances in therapeutic resources, roughly half RA patients failed achieve T2T goals and 55.2% developed erosive disease. The frequent use of corticosteroids and delay in initiating DMARDs were demonstrated. Issues concerning timely access to medical care are crucial for effective management.(AU)

Rheumatoid arthritis (RA) is an autoimmune disease of knee joints involving pain and inflammation. Rhoifolin is a plant flavonoid known to have antioxidant and anti-inflammatory properties. This study was taken to identify the effect of rhoifolin on complete Freund's adjuvant (CFA)-induced arthritis in the rat model. Treatment with rhoifolin (10 and 20 mg/kg) showed a significant improvement in the overall health parameters such as paw edema and weight loss. This improvement in morphological parameters corroborated the findings with gross morphological changes observed in the histopathological analysis. Rhoifolin treatment also caused a significant decrease in oxidative stress, evident from changes in intracellular levels of glutathione, glutathione peroxidase, malondialdehyde, and superoxide dismutase in the articular cartilage tissue. Moreover, proinflammatory cytokines, tumor necrosis factor (TNF)-α, interleukin(IL)-1β, and IL-6 showed a significant downregulation of gene expression and intracellular protein concentration levels. The NF-κB pathway showed a significant attenuation as evident in the significant reduction in the levels of NF-κB p65 and p-IκB-α. These results indicated that rhoifolin can be a natural therapeutic alternative to the extant regimens, which include non-steroidal anti-inflammatory drugs and immunosuppressants. Additionally, the antioxidant and anti-inflammatory action of rhoifolin was probably mediated by the NF-κB pathway. However, the exact target molecules of this pathway need to be determined in further studies.

OBJECTIVE@#To explore the mechanism of @*METHODS@#Healthy male DBA/1 mice were used for CIA modeling. Twenty-five CIA mice with successful modeling and similar arthritis index (AI) scores were randomized equally into model group (CIA), methotrexate (MTX) group, and low-, medium-, and high-dose XWGD groups (0.975, 1.95, and 3.9 g/mL, respectively), with another 5 normal mice as the normal control group. The mice in normal control and CIA groups were given saline once a day, those in MTX group were given 0.1 mg/mL MTX once a week, and those in XWGD groups were treated daily via garage of XWGD containing crude drugs of different doses for 28 consecutive days. The AI score and HE staining were used to evaluate the changes in the joints of the CIA mice. The effect of XWGD on Th1, Th17, MDSC, G-MDSC and M-MDSC cells were evaluated with flow cytometry.@*RESULTS@#Treatment with MTX and different doses of XWGD significantly decreased the AI score of the mice and relieved joint inflammation as compared with the model group (@*CONCLUSIONS@#XWGD can improve joint inflammation in CIA mice by increasing the percentages of G-MDSC cells and decreasing the percentages of M-MDSC, Th1 and Th17 cells, and a high dose of XWGD can produce an equivalent therapeutic effect to methotrexate but with better safety.

As demências rapidamente progressivas são condições que impactam a vida do paciente, entretanto nem sempre são consideradas durante a investigação da síndrome demencial. Este relato descreve uma paciente portadora de artrite reumatoide em uso crônico de corticoterapia que evoluiu com um quadro de demência rapidamente progressiva no período de cinco meses. Durante a investigação, evidenciou-se o linfoma primário de sistema nervoso central como causa de sua síndrome demencial. Faz-se importante destacar que o uso prolongado de corticoide pode estar associado a um estado de imunossupressão, o que é fator de risco para o surgimento do linfoma de sistema nervoso central.

Rapidly progressive dementias are conditions that worsening the patient's life; however they are not always considered during the investigation of dementia syndrome. This report describes the case of a patient with rheumatoid arthritis and chronic use of corticosteroid therapy, who developed rapidly progressive dementia within 5 months. During the investigation, the primary lymphoma of the central nervous system was evidenced as the cause of its dementia syndrome. Importantly, prolonged use of corticosteroids may be associated with a state of immunosuppression, which is a risk factor for the onset of central nervous system lymphoma.

ABSTRACT Purpose: To investigate the frequency of toxic retinopathy in patients with lupus erythematosus and rheumatoid arthritis with long-term use of chloroquine diphosphate or hydroxychloroquine through spectral domain optical coherence tomography and the outcomes of ophthalmological exams (visual acuity - Snellen's table, color vision test - Ishihara's table, fundoscopy, and retinography - red-free). Methods: A cross-sectional study was carried out involving the ophthalmologic evaluation of patients using regular chloroquine diphosphate or hydroxychloroquine for a period of 1 year or longer. The patients completed a questionnaire on their opinions and treatment regularity. The same patients underwent ophthalmologic examination and spectral domain optical coherence tomography. Results: The prevalence of toxic retinopathy caused by antimalarials was 4.15% (9 of 217 patients), 7.4% (4 of 54 patients) following chloroquine diphosphate usage, and 0.82% (1 of 121 patients) following hydroxychloroquine usage. Only patients with advanced stage maculopathy presented abnormalities during the ophthalmologic exam: the color vision test was altered in 11.1%, and visual acuity and fundoscopy were altered in 33.3%. Identification of early toxic retinopathy, detected in six patients, was possible using spectral domain optical coherence tomography. The mean duration of antimalarial drug usage among patients with toxic retinopathy was 10.4 years. Only 31% of the patients reported some symptoms during treatment, and although 24% were afraid to use the medication, they did so as prescribed. Conclusion: Use of spectral domain optical coherence tomography was essential for the diagnosis of early-stage antimalarial toxic retinopathy in patients with the following characteristics: asymptomatic, antimalarial use 7 days a week for a period of more than 5 years, and normal clinical ophthalmologic examination.

RESUMO Objetivo: Investigar a frequência da retinopatia tóxica em pacientes com lúpus eritematoso e artrite reumatóide com uso crônico de difosfato de cloroquina ou hidroxicloroquina, através de tomografia de coerência óptica de domínio espectral e os resultados dos exames oftalmológicos (acuidade visual - tabela de Snellen, teste de visão de cor - tabela de Ishihara, fundoscopia e retinografia - red free). Métodos: Foi realizado um estudo transversal envolvendo a avaliação oftalmológica de pacientes em uso regular de difosfato de cloroquina ou hidroxicloroquina por um período de um ano ou mais. Os pacientes responderam a um questionário sobre a sua opinião e regularidade do tratamento. Os mesmos pacientes realizaram exame oftalmológico clínico e tomografia de coerência óptica de domínio espectral. Resultados: A prevalência de retinopatia tóxica por antimaláricos foi de 4,15% (9 dos 217 pacientes), 7,4% (4 de 54 pacientes) após uso de difosfato de cloroquina e 0,82% (1 de 121 pacientes) após uso de hidroxicloroquina. Apenas os pacientes com maculopatia em fase avançada apresentaram alterações durante os exames clínicos: teste de visão de cores alterado em 11,1%, e a acuidade visual e fundoscopia foram alteradas em 33,3%. A identificação de retinopatia tóxica precoce, detectada em seis pacientes, foi possível por meio da tomografia de coerência óptica de domínio espectral. A duração média do tempo de uso de drogas antimaláricas entre os pacientes com retinopatia tóxica foi de 10,4 anos. Apenas 31% dos pacientes relataram algum sintoma durante o tratamento e apesar de 24% terem medo de usar a medicação, eles o fizeram conforme prescrito. Conclusão: O uso da tomografia de coerência óptica de domínio espectral foi essencial para o diagnóstico de retinopatia tóxica antimalárica em estágio inicial em pacientes com as seguintes características: uso assintomático, antimalárico 7 dias por semana por um período maior que cinco anos e exame oftalmológico clínico normal.

INTRODUCCIÓN Se ha planteado que factores ambientales y relacionados con el estilo de vida pueden contribuir a la severidad y progresión de la inflamación en la artritis reumatoide. Una intervención que genera un alto interés, debido a sus supuestas propiedades antiinflamatorias es la dieta mediterránea. MÉTODOS Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES Identificamos siete revisiones sistemáticas que en conjunto incluyeron cuatro estudios primarios, de los cuales sólo uno corresponde a un ensayo aleatorizado. Concluimos que la dieta mediterránea podría hacer poca o nula diferencia en el dolor articular o actividad de la enfermedad, y aumentar levemente el peso en pacientes con artritis reumatoide, pero la certeza de la evidencia es baja. Por otra parte, no es posible establecer con claridad si la dieta mediterránea tiene algún efecto sobre la funcionalidad, rigidez matinal o calidad de vida, debido a que la certeza de la evidencia existente ha sido evaluada como muy baja.

INTRODUCTION It has been suggested that environmental and lifestyle factors might contribute to the severity and progression of inflammation in rheumatoid arthritis. An intervention generating high interest due to its supposed anti-inflammatory properties is the Mediterranean diet. METHODS We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS We identified seven systematic reviews including four primary studies, of which only one corresponded to a randomized trial. We concluded Mediterranean diet may make little or no difference in pain or disease activity and may slightly increase weight in rheumatoid arthritis patients, but the certainty of the evidence is low. On the other hand, it was not possible to clearly establish whether Mediterranean diet has any effect on functionality, morning stiffness or quality of life as the certainty of the existing evidence has been assessed as very low.

La artritis reumatoide (AR) es una enfermedad inflamatoria sistémica de origen autoinmune, caracterizada por una evolución variable, con remisiones y reacti-vaciones. Se considera que un diagnóstico y tratamiento precoz permiten evitar el daño articular, mejorar el pronóstico y la calidad de vida del paciente. El trata-miento actual está basado en el uso de fármacos antirreumáticos sintéticos mo-dificadores de la enfermedad (sDMARDS), asociado a glucocorticoides en dosis bajas. Frente al fracaso o intolerancia de este tratamiento o bien en casos de una enfermedad inicial muy severa, en especial con manifestaciones extraarticulares, se recomienda el uso de fármacos biológicos modificadores de la enfermedad (bDMARD). Estos fármacos, usados en las condiciones señaladas, han significado un avance importante en el control y pronóstico de la enfermedad. Sin embargo, no están exentos de la presencia de reacciones adversas, por lo que deben ser monitorizados permanentemente.

Rheumatoid arthritis (RA) is a systemic inflammatory disease of autoimmune ori-gin, characterized by a variable evolution, with remissions and reactivations. It is considered that a diagnosis and early treatment allow avoiding the joint damage, improving the prognosis and the quality of life of the patient. The current treat-ment is based on the use of synthetic antirheumatic drugs modifying the disease (sDMARDS), associated with low-dose glucocorticoids. Faced with the failure or intolerance of this treatment or in cases of a very severe initial disease, especially with extra-articular manifestations, the use of biological drugs that modify the disease (bDMARD) is recommended. These drugs, used in the indicated condi-tions, have meant an important advance in the control and prognosis of the dis-ease. However, they are not exempt from the presence of adverse reactions, so they should be monitored permanently.
