34413630 Biological Therapies for Rheumatoid Arthritis: An Overview for the Clinician. 2021 Rheumatoid arthritis (RA) is a disease characterised by inflammation of synovial joints and poses a substantial healthcare burden on both the individual and society. One of the most significant shifts in the RA therapeutic landscape has occurred with the introduction of biological disease modifying anti-rheumatic drugs (bDMARDs). There are five classes of bDMARDs currently available, each with a different molecular target and subtle differences in their efficacy and safety profile. This review also describes the "real-world" use of bDMARDs and how they fit into the overall RA treatment guidelines.
34916763 Does non-surgical periodontal treatment influence on rheumatoid arthritis? A systematic r 2021 Dec OBJECTIVE: The objective of this systematic review was to evaluate the efficacy of non-surgical periodontal therapy on rheumatoid arthritis activity. MATERIAL AND METHODS: Articles published until April 2019 were electronically searched and screened using PubMed / MEDLINE, Scopus, and Cochrane databases according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). This study was recorded in the international PROSPERO database (CRD42019132205). The PICO question (population, intervention, comparison, results) was: in adult patients with rheumatoid arthritis and periodontitis (P), does non-surgical periodontal treatment (I), as compared to no treatment (C), provides better outcomes in rheumatoid arthritis activity (O). RESULTS: After searching the databases, seven articles were selected for qualitative and five for quantitative analysis. The total number of participants included was 292, with an average age of 50.5 years. All patients had rheumatoid arthritis and periodontal disease. Non-surgical periodontal treatment significantly reduced Disease Activity Score 28 (P = 0.004; I(2) = 92%) and erythrocyte sedimentation rate (P = 0.01; I(2) = 78%), but with no significant effect on C-reactive protein (P = 0.34; I(2) = 92%). CONCLUSIONS: It can be concluded that non-surgical periodontal treatment can benefit patients with rheumatoid arthritis.
34849628 Rheumatoid arthritis patients treated with Janus kinase inhibitors show reduced humoral im 2021 Nov 25 OBJECTIVES: The mRNA-based COVID-19 vaccines are now employed globally and have shown high efficacy in preventing SARS-CoV-2 infection. However, less is known about the vaccine efficacy in immune suppressed individuals. This study sought to explore whether humoral immunity to the COVID-19 vaccine BNT162b2 is altered in rheumatoid arthritis patients treated with Janus kinase inhibitors by analyzing antibodies titer, neutralization activity and B cell responses. METHODS: We collected plasma samples from 12 rheumatoid arthritis patients who were treated with Janus kinase inhibitors and received two doses of the BNT162b2 vaccine, as well as 26 healthy individuals who were vaccinated with the same vaccine. We analyzed the quantity of the anti-spike IgG and IgA antibodies that were elicited following the BNT162b2 vaccination, the plasma neutralization capacity and the responsiveness of the B-lymphocytes. We used ELISA to quantify antibody titers, and plasma neutralization assay was used to determine virus neutralization capacity. Alteration in expression of genes that are associated with B cell activation and germinal center response were analyzed by qPCR. RESULTS: Reduced levels of anti-spike IgG antibodies and neutralization capacity were seen in the rheumatoid arthritis patients who were treated with JAK inhibitors in comparison with healthy individuals. Furthermore, B cell responsiveness to the SARS-CoV-2 spike protein were reduced in the rheumatoid arthritis patients. CONCLUSION: Rheumatoid arthritis patients who are treated with JAK inhibitors show suppressed humoral response following BNT162b2 vaccination, as revealed by the quantity and quality of the anti-spike antibodies.
34065638 Probiotics and Amelioration of Rheumatoid Arthritis: Significant Roles of Lactobacillus ca 2021 May 16 Rheumatoid arthritis is a chronic autoimmune disorder that can lead to disability conditions with swollen joints, pain, stiffness, cartilage degradation, and osteoporosis. Genetic, epigenetic, sex-specific factors, smoking, air pollution, food, oral hygiene, periodontitis, Prevotella, and imbalance in the gastrointestinal microbiota are possible sources of the initiation or progression of rheumatoid arthritis, although the detailed mechanisms still need to be elucidated. Probiotics containing Lactobacillus spp. are commonly used as alleviating agents or food supplements to manage diarrhea, dysentery, develop immunity, and maintain general health. The mechanism of action of Lactobacillus spp. against rheumatoid arthritis is still not clearly known to date. In this narrative review, we recapitulate the findings of recent studies to understand the overall pathogenesis of rheumatoid arthritis and the roles of probiotics, particularly L. casei or L. acidophilus, in the management of rheumatoid arthritis in clinical and preclinical studies.
31606270 Anti-arthritic potential of ethanol and aqueous extracts of stem bark of Cleistopholis pat 2021 Jan BACKGROUND: Traditional medicine intervention has been used in rheumatoid arthritis (RA) treatment due to limitations of conventional drugs. OBJECTIVE: This study aimed at evaluating the anti-arthritic potentials of ethanol and aqueous extracts of stem bark of Cleistopholis patens (SBCP) in complete Freund's adjuvant (CFA) induced rheumatoid arthritis in rats. MATERIALS AND METHODS: Rheumatoid arthritis was induced in groups 2 to 9 by intradermal injection of 0.1 mlkg(-1) chicken type II collagen in CFA into the left hind paw of the rats. Group 1 served as normal control. Group 2 (negative control) received 5 mlkg(-1) body weight normal saline while group 3 (positive control) received 10 mg/kg body weight standard drug (indomethacin). Groups 4 to 9 received varied doses of the extracts. After 10 days of RA induction, rats were treated with ethanol and aqueous extracts of SBCP orally at a dose of 400, 600 and 800 mgkg(-1) for 21 days. The paw size, body weight changes, inflammatory parameters, lipid peroxidation maker and malondialdehyde (MDA) were assessed. RESULTS: Rheumatoid arthritis induction caused marked (p < 0.05) increase in paw size, inflammatory makers and MDA while significant (p < 0.05) reduction was observed in body weight relative to normal control. Treatment with extracts analogous to indomethacin markedly (p < 0.05) decreased the paw size and caused weight gain while the altered inflammatory parameters and MDA were reversed relative to negative control. CONCLUSION: The findings suggest that the extracts of SBCP have good antiarthritic potentials comparable to indomethacin and hence could be used in rheumatoid arthritis management.
33948124 The sonographic identification of cortical bone interruptions in rheumatoid arthritis: a m 2021 Bone erosions are the hallmark of structural damage in rheumatoid arthritis (RA). Among imaging techniques, ultrasonography (US) has emerged as an accurate, reliable, repeatable, low-cost and non-invasive imaging modality to detect erosive changes in RA. However, small interruptions of the cortical bone detectable by last generation US equipment do not necessarily represent bone erosions. According to the available data, in addition to cortical bone interruption itself, only a few morphological US findings have been proposed to define RA bone erosions. However, other additional features may be considered to facilitate the interpretation of US cortical bone interruptions in RA. These could be summarised using the following four domains: size, site, shape and scenery. This hypothesis article provides a critical literature review of US features characteristic of RA bone erosions and pictorial evidence supporting the potential role of a morphological analysis in the US identification of bone erosions in RA patients. PLAIN LANGUAGE SUMMARY: The ultrasonographic morphology of cortical interruptions is helpful for the identification of bone erosions in rheumatoid arthritis: the "four Ss" approach Bone erosions are characteristic features of rheumatoid arthritis. They are associated with a more aggressive disease and with irreversible physical disability. In recent years, ultrasonography has emerged as an accurate and reliable technique for the detection of bone erosions, that appear as interruptions of the cortical bone with variable size. However, cortical bone interruptions do not necessarily represent bone erosions. Since bone erosions represent the earliest evidence of the destructive behaviour of RA, their identification is crucial.Besides the cortical interruption itself, only a few morphological ultrasonographic features were proposed to characterise bone erosions in rheumatoid arthritis.We believe that a morphological approach, including size, site, shape and scenery, may be considered to facilitate the interpretation of ultrasonographic cortical bone interruptions in rheumatoid arthritis.In this hypothesis article we carried out a critical review of the scientific literature and provided extensive pictorial evidence of the ultrasonographic spectrum of cortical interruptions supporting the potential role of considering the "four Ss" for the ultrasonographic identification of bone erosions in rheumatoid arthritis.
34725598 Septic Arthritis Masquerading as a Flare of Rheumatoid Arthritis: A Not So Straightforward 2021 Sep A typical presentation of septic arthritis (SA) includes pain, swelling, and erythema in the affected joint. Often, patients complain of inability to bear weight on the affected limb. However, some patients may present with subtle symptoms of pain and no fever or obvious swelling of the affected limb thus making the initial suspicion of SA low. Especially, patients with rheumatoid arthritis (RA) may present with polyarticular joint pain and initial synovial fluid analysis from an infected joint not consistent with overt septic arthritis. In such situations, the diagnosis of septic arthritis could be missed on delayed. In this case report, we present a 79-year-old female with a history of RA who presents with polyarticular pain, most notably in her right knee. SA was not initially suspected because of her history of RA and her current presentation with polyarticular pain. The initial synovial analysis did not suggest SA as well. However, cultures of synovial fluid from her right knee confirmed SA. Thus, we have highlighted that physicians should have a high suspicion for SA when addressing joint pain in RA patients.
34309127 Current status and influencing factors of fatigue in patients with rheumatoid arthritis: A 2021 Jul 26 AIM: This study aimed to explore the level and influencing factors of fatigue in patients with rheumatoid arthritis. METHODS: This cross-sectional study was conducted in 243 patients with rheumatoid arthritis from April 2016 to March 2017. The Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire, Arthritis Self-Efficacy Scale-8, Visual Analogue Scale for pain, physical function subscale of Short Form 36-Item Health Survey, Hospital Anxiety and Depression Scale, Perceived Social Support Scale, Pittsburgh Sleep Quality Index and a self-designed demographic and disease-related information questionnaire were used to collect the data. Stepwise linear multiple regression was used to clarify the impact of statistically significant variables (P < 0.05) in the independent sample t test, one-way ANOVA and correlation analysis on the level of fatigue. RESULTS: Stepwise linear multiple regression analyses showed that disease activity, self-efficacy, physical function, pain, depression, duration of morning stiffness and anxiety were major factors influencing fatigue in patients with rheumatoid arthritis, which explained 59.5% of the total variance. CONCLUSION: Our study demonstrated a moderate level of fatigue in Chinese patients with rheumatoid arthritis. In clinical practice, nurses should explore individualized intervention programmes based on related predictors of fatigue to help patients relieve fatigue.
31643529 Antirheumatic Agents. 2012 The term "antirheumatic drugs" refers to agents used in the therapy of inflammatory arthritis, predominantly rheumatoid arthritis, but also idiopathic juvenile arthritis, psoriatic arthritis, ankylosing spondylitis and others. Aspirin, the nonsteroidal antiinflammatory agents and corticosteroids are used commonly in these conditions, but have little effect in altering the natural history and outcomes of inflammatory arthritis, which can lead to cartilage and joint destruction and severe disability. More important and diverse are the "Disease-Modifying Anti-Rheumatic Drugs" (DMARDs) which are the mainstay of therapy in rheumatoid arthritis and have dramatically altered the outcome of these conditions, and improved the quality of life of patients with rheumatoid arthritis. The initial DMARDs were the gold preparations which were first used in the 1930s. More potent and better tolerated agents followed in the 1950s and 1960s, including methotrexate, hydroxychloroquine, sulfasalazine, penicillamine, azathioprine and the thiopurines. More modern DMARDs have included potent, small molecule immunosuppressive agents such as leflunomide, cyclosporine, tacrolimus and mycophenolate. More recently, monoclonal antibodies and biologics have been developed that act on the primary cytokines and inflammatory pathways that are active and play a major role in rheumatoid arthritis. These important agents include the tumor necrosis factor antagonists, anticytokines (such as anakinra) and other major immunosuppressive agents (rituximab, abatacept, and tocilizumab). Agents used predominantly as antirheumatic drugs are listed below with specific links to the individual drugs. Medications for gout are given under "Antigout Agents" and nonsteroid antiinflammatory agents under "NSAIDs".
35027956 Naringenin nanocrystals for improving anti-rheumatoid arthritis activity. 2021 Nov Naringenin (NAR) is recognized for its anti-inflammatory activity. However, the clinical application of NAR is limited by low bioavailability, which is attributed to its poor aqueous solubility. In this study, we aimed to improve the therapeutic efficacy of NAR by formulating it into nanocrystals (NCs) via wet milling. The obtained NARNCs exhibited superior dissolution behaviors, increased cellular uptake, and enhanced transcellular diffusion relative to those of bulk NAR. Oral administration of NARNCs also significantly improved bioavailability in rats. In addition, the NARNCs effectively improved rheumatoid arthritis treatment in collagen-induced arthritic rats by reducing inflammatory cell infiltration and synovial damage. These results indicate that NARNCs provides a promising strategy for rheumatoid arthritis treatment.
34108880 Pharmacokinetics-Based Chronoefficacy of Semen Strychni and Tripterygium Glycoside Tablet 2021 Rheumatoid arthritis is a systemic autoimmune disease characterized by synovial inflammation and bone destruction. Identifying drugs with time-varying efficacy and toxicity, and elucidating the mechanisms would help to improve treatment efficacy and reduce adverse effects. Here, we aimed to determine the chronoefficacy of semen strychni (SS) and tripterygium glycoside tablet (TGT) against rheumatoid arthritis in mice, and to investigate a potential role of circadian pharmacokinetics in generating chronoefficacy. SS extract and TGT suspension were prepared with ultrasonication. Effects of SS and TGT on collagen-induced arthritis (CIA) were evaluated by measuring TNF-α and IL-6 levels. SS dosed at ZT18 was more effective in protecting against CIA than drug dosed at ZT6 (i.e., lower levels of key inflammatory factors at ZT18 than at ZT6). This was accompanied by higher systemic exposure levels of strychnine and brucine (two main putative active ingredients of SS) in ZT18-treated than in ZT6-treated CIA mice. TGT dosing at ZT2 showed a better efficacy against CIA as compared to herb doing at ZT14. Consistently, ZT2 dosing generated a higher exposure of triptolide (a main putative active ingredient of TGT) as compared to ZT14 dosing in CIA mice. Moreover, strychnine, brucine, and triptolide significantly inhibited the proliferation of fibroblast-like synoviocytes, and reduced the production of TNF-α and IL-6 and the mRNAs of TNF-α, IL-6, COX-2, and iNOS, suggesting that they possessed an anti-arthritis activity. In conclusion, SS and TGT display chronoefficacy against rheumatoid arthritis in mice, that is attributed to circadian pharmacokinetics of main active ingredients. Our findings have implications for improving treatment outcomes of SS and TGT via timed delivery.
33915757 The Immunomodulatory and Anti-Inflammatory Effect of Curcumin on Immune Cell Populations, 2021 Apr 1 Rheumatoid arthritis (RA) is a widespread chronic autoimmune disorder affecting the joints, causing irreversible cartilage, synovium, and bone degradation. During the course of the disease, many immune and joint cells are activated, causing inflammation. Immune cells including macrophages, lymphocytes, neutrophils, mast cells, natural killer cells, innate lymphoid cells, as well as synovial tissue cells, like fibroblast-like synoviocytes, chondrocytes, and osteoclasts secrete different proinflammatory factors, including many cytokines, angiogenesis-stimulating molecules and others. Recent studies reveal that curcumin, a natural dietary anti-inflammatory compound, can modulate the response of the cells engaging in RA course. This review comprises detailed data about the pathogenesis and inflammation process in rheumatoid arthritis and demonstrates scientific investigations about the molecular interactions between curcumin and immune cells responsible for rheumatoid arthritis development to discuss this herbal drug's immunoregulatory role in RA treatment.
34104009 Current and Emerging DMARDs for the Treatment of Rheumatoid Arthritis. 2021 Rheumatoid arthritis (RA) is the most prevalent form of inflammatory arthritis. It is a profoundly serious and severe disease that if it goes untreated could have severe consequences to the joints and health of the patient who carries this diagnosis. The treatment of RA has dramatically changed since the year 2000, with the discovery of the TNFis, then other biologics, and finally the JAKi. All these new medications with or without methotrexate in combination, tight control and treat to target have produced a revolution in the outcome of this disease. We reviewed and summarized the treatment options, and the most significant papers for each one of these new drugs. The reader could have a full picture with all the references of the recent publications. We also updated the biosimilar situation in RA, as well as the new drugs that will be coming to the market in the next 5 years.
33573706 Potential contributors to low dose methotrexate toxicity in a patient with rheumatoid arth 2021 Feb 12 BACKGROUND: Low dose methotrexate toxicity rarely occurs, but may present with severe complications, such as pancytopenia, hepatotoxicity, mucositis, and pneumonitis. Known risk factors for methotrexate toxicity include dosing errors, metabolic syndrome, hypoalbuminemia, renal dysfunction, lack of folate supplementation, and the concomitant use of drugs that interfere with methotrexate metabolism. Vitamin B12 deficiency leads to megaloblastic anemia and may cause pancytopenia, but its role in methotrexate toxicity has not been described. CASE PRESENTATION: We present a case of a patient with rheumatoid arthritis who was admitted with febrile neutropenia, pancytopenia, and severe mucositis, likely secondary to low dose methotrexate toxicity. She had multiple factors that potentially contributed to the development of toxicity, including concurrent sulfasalazine use for rheumatoid arthritis. An evaluation of the patient's macrocytic anemia revealed pernicious anemia. The patient's illness resolved with cessation of methotrexate and sulfasalazine, leucovorin treatment and vitamin B12 repletion. CONCLUSIONS: This case illustrates the multiple factors that may potentially contribute to low dose methotrexate toxicity and highlights the importance of testing for vitamin B12 deficiency in rheumatoid arthritis patients with macrocytic anemia. Addressing all the modifiable factors that potentially contribute to low dose methotrexate toxicity may improve outcomes.
34291892 An m-Health Intervention for Rheumatoid Arthritis in China ("Rheumatism Center" app): Stud 2021 Jul 22 AIM: To study the feasibility and effectiveness of a m-Health app in improving the management of rheumatoid arthritis. DESIGN: Randomized controlled trial. METHODS: Sixty rheumatoid arthritis participants will be recruited for a 6-month feasibility study. Patients meeting the inclusion criteria will be randomly allocated to receive standard care or standard care plus the m-Health intervention. The primary outcome is the feasibility of a randomized controlled trial. In addition, we will investigate patient satisfaction in using the "Rheumatism Center" app in the intervention group. The secondary outcomes include the scores for the simplified disease activity index, clinical disease activity index, disease activity score 28, health assessment questionnaire and 6-item self-efficacy scale for chronic diseases. The assessments will be performed at baseline and at 4 weeks, 3 months and 6 months after the study is initiated. At the end of the study, we will also collect user views of the app through qualitative interviews. RESULTS: This study is ongoing. The findings of this study will determine the feasibility and effectiveness of m-Health intervention in the management of rheumatoid arthritis, hoping to enhance the awareness of disease management and quality of life for rheumatoid arthritis patients.
33531797 Adherence to Treatment in Patients with Rheumatoid Arthritis from Spain. 2021 OBJECTIVE: To evaluate adherence to treatment in a cohort of patients with rheumatoid arthritis in Spain and to identify potential predictors of adherence. METHODS: An observational, cross-sectional, multicenter study in outpatient clinics of Rheumatology Departments from 41 centers was conducted. A validated Spanish version of the compliance questionnaire in Rheumatology was used to measure adherence in a cohort of patients with rheumatoid arthritis, representative of the Spanish population. Univariate and multivariate analyses were performed to detect predictors of adherence. RESULTS: A total of 859 patients were recruited. An adherence rate of 79% was established. No differences were detected in adherence in patients receiving biologic disease-modifying antirheumatic drugs compared to conventional disease-modifying antirheumatic drugs, in patients receiving intravenous therapies compared to other routes of administration and in patients treated in specific day hospitals compared to polyvalent day hospitals. The number of drugs and cohabitation were independent predictors of adherence. CONCLUSION: An inexpensive and useful method was used to measure adherence in Spanish population. The adherence rate in rheumatoid arthritis is still suboptimal. Simpler, more convenient dosing regimens may improve compliance. Increased knowledge of compliance in patients with rheumatoid arthritis and the identification of possible predictors of adherence will allow to develop effective intervention strategies.
34539070 Quality of life and life-space mobility after total knee arthroplasty in patients with rhe 2021 Sep [Purpose] The purpose of this study was to identify factors inhibiting improvement in the quality of life after total knee arthroplasty in patients with rheumatoid arthritis. [Participants and Methods] This was a pilot case-control study. The sample comprised of five participants with rheumatoid arthritis and 11 participants with osteoarthritis, who underwent total knee arthroplasty. We compared the groups in terms of physical function, walking ability, Japanese Knee Osteoarthritis Measure, and Life-Space Assessment. Measurements were taken before surgery and at four weeks and five months post-surgery. All patients underwent rehabilitation for five months postoperatively, first as inpatients, and then as outpatients after discharge. [Results] In the period from 4 weeks to 5 months post-surgery, physical function improved similarly in both groups in terms of muscle strength and walking ability. Despite the patients with rheumatoid arthritis being younger, their self-health assessment score by the Japanese Knee Osteoarthritis Measure and measures of life-space mobility by Life-Space Assessment were lower. [Conclusion] It is important to consider exercise therapy, and gait instruction to alleviate anxiety about health status and improve the quality of life and life-space mobility in patients with rheumatoid arthritis who undergo total knee arthroplasty.
34417134 Recurrent Pericarditis After Covid-19. 2021 Jul 30 Patient with rheumatoid arthritis who has Covid-19 with recurrent pericaditis debut, differential diagnosis.
34842780 Rationale and Design of the Orencia Atherosclerosis and Rheumatoid Arthritis Study (ORACLE 2021 Nov 15 To explore the biological and immunological basis of human rheumatoid arthritis and human atherosclerosis, we planned and reported a detailed design and rationale for Orencia Atherosclerosis and Rheumatoid Arthritis Study (ORACLE Arthritis Study) using highly sensitive, high-throughput, human autoantibody measurement methods with cell-free protein synthesis technologies. Our previous study revealed that subjects with atherosclerosis had various autoantibodies in their sera, and the titers of anti-Th2 cytokine antibodies were correlated with the severity of atherosclerosis. Because rheumatoid arthritis is a representative autoimmune disease, we hypothesized that both rheumatoid arthritis and atherosclerosis are commonly developed by autoantibody-mediated autoimmune processes, leading to incessant inflammatory changes in both articular joint tissues and vessel walls. We planned a detailed examination involving carotid artery ultrasonography, measurements of adhesion molecules, such as ICAM-1 (intercellular adhesion molecule 1) and VCAM-1 (vascular cell adhesion molecule 1) for the evaluation of atherosclerosis progression, and high-throughput, high-sensitivity, autoantibody analyses using cell-free technologies, with detailed examinations of the disease activity of rheumatoid arthritis. Analyses of correlations and associations between biological markers and degrees of carotid atherosclerosis over time under consistent conditions may enable us to understand the biological and humoral immunity background of human atherosclerosis and autoimmune diseases.
34068884 Rheumatoid Arthritis Associated Episcleritis and Scleritis: An Update on Treatment Perspec 2021 May 14 Episcleritis and scleritis are the most common ocular inflammatory manifestation of rheumatoid arthritis. Rheumatoid arthritis (RA) accounts for 8% to 15% of the cases of scleritis, and 2% of patients with RA will develop scleritis. These patients are more likely to present with diffuse or necrotizing forms of scleritis and have an increased risk of ocular complications and refractory scleral inflammation. In this review we provide an overview of diagnosis and management of rheumatoid arthritis-associated episcleritis and scleritis with a focus on recent treatment perspectives. Episcleritis is usually benign and treated with oral non-steroidal anti- inflammatory drugs (NSAIDs) and/or topical steroids. Treatment of scleritis will classically include oral NSAIDs and steroids but may require disease-modifying anti-rheumatic drugs (DMARDs). In refractory cases, treatment with anti TNF biologic agents (infliximab, and adalimumab) is now recommended. Evidence suggests that rituximab may be an effective option, and further studies are needed to investigate the potential role of gevokizumab, tocilizumab, abatacept, tofacitinib, or ACTH gel. A close cooperation is needed between the rheumatology or internal medicine specialist and the ophthalmologist, especially when scleritis may be the first indicator of an underlying rheumatoid vasculitis.
