Long-term sustainability of response to upadacitinib among patients with active rheumatoid arthritis refractory to biological treatments: results up to 5 years from SELECT-BEYOND. RMD Open 2024; 10:e004037. [PMID: 39053948 DOI: 10.1136/rmdopen-2023-004037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 05/04/2024] [Indexed: 07/27/2024] Open
Abstract
OBJECTIVE To evaluate the long-term sustainability of response to the Janus kinase inhibitor upadacitinib among patients with rheumatoid arthritis and an inadequate response or intolerance to biological disease-modifying antirheumatic drugs (bDMARD-IR) in the SELECT-BEYOND phase 3 trial. METHODS Patients on background conventional synthetic DMARDs (csDMARDs) were treated once daily with upadacitinib 15 mg or placebo. Patients who completed the week 24 visit could enter a long-term extension of up to 5 years. The sustainability of response was assessed based on achievement of Clinical Disease Activity Index (CDAI), Simplified Disease Activity Index (SDAI) and Disease Activity Score 28-joint count using C-reactive protein (DAS28 (CRP)) targets and evaluated up to week 260 in all patients receiving the approved upadacitinib 15 mg dose, including those randomised to upadacitinib 15 mg and those who switched from placebo to upadacitinib 15 mg at week 12. RESULTS In this bDMARD-IR population, 45% (n=104/229) and 79% (n=172/219) of patients treated with upadacitinib 15 mg plus background csDMARD(s) achieved CDAI remission or CDAI low disease activity (LDA) at any point during the 5-year study, respectively. Of those who achieved CDAI remission/LDA, 25%/43% maintained their initial response through 240 weeks of follow-up after first achieving response. Most patients who lost remission or LDA were able to recapture that response by the cut-off date. Similar overall results were observed for SDAI and DAS28 (CRP). No strong predictors of response were identified. CONCLUSIONS Over three-quarters of bDMARD-IR patients achieved CDAI LDA with upadacitinib, and almost half of those maintained LDA through 240 weeks of follow-up. Remission was achieved by nearly half of all patients and maintained in approximately a quarter of those achieving remission. TRIAL REGISTRATION NUMBER NCT02706847.

Abstract
PURPOSE This study aimed to investigate the efficacy and safety of ultrasound-guided percutaneous radiofrequency ablation (RFA) for the treatment of synovial hyperplasia in the knee joints of antigen-induced arthritis (AIA) model rabbits. METHODS Forty Japanese large-eared white rabbits were divided into AIA and control groups. After successful induction of the AIA model, the knee joints were randomly assigned to RFA and non-RFA groups. The RFA group underwent ultrasound-guided RFA to treat synovial hyperplasia in the knee joint. Dynamic observation of various detection indices was conducted to evaluate the safety and effectiveness of the RFA procedure. RESULTS Successful synovial ablation was achieved in the RFA group, with no intraoperative or perioperative mortality. Postoperative the circumference of the knee joint reached a peak before decreasing in the third week after surgery. The incidence and diameter of postoperative skin ulcers were not significantly different compared to the non-RFA group (p > .05). Anatomical examination revealed an intact intermuscular fascia around the ablated area in the RFA group. The ablated synovial tissue initially presented as a white mass, which subsequently liquefied into a milky white viscous fluid. Gross articular cartilage was observed, along with liquefied necrosis of the synovium on pathological histology and infiltration of inflammatory cells in the surrounding soft tissue. CONCLUSION The experimental results demonstrated that ultrasound-guided RFA of the knee in the treatment of synovial hyperplasia in AIA model animals was both effective and safe.

Arch Biochem Biophys 2024; 755:109965. [PMID: 38552763 DOI: 10.1016/j.abb.2024.109965] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 03/17/2024] [Accepted: 03/21/2024] [Indexed: 04/24/2024]
Abstract
BACKGROUND Rheumatoid arthritis (RA) is currently an autoimmune inflammatory disease with an unclear pathogenesis. Fibroblast-like synoviocytes (FLSs) have tumor-like properties, and their activation and secretion of pro-inflammatory factors are important factors in joint destruction. Wogonin (5,7-dihydroxy-8-methoxyflavone), a natural flavonoid isolated from Scutellaria baicalensis root, has been shown to have significant anti-inflammatory, anti-oxidative stress, and anti-tumor effects in a variety of diseases. However, the role of wogonin in RA has not yet been demonstrated. PURPOSE To investigate the inhibitory effect of wogonin on the invasive behavior of fibroblast-like synoviocytes and to explore the mechanism of action of wogonin in RA. METHODS CCK-8, EdU, cell migration and invasion, immunofluorescence staining, RT-qPCR, and protein blot analysis were used to study the inhibitory effects of wogonin on migration, invasion, and pro-inflammatory cytokine overexpression in the immortalized rheumatoid synovial cell line MH7A. The therapeutic effects of wogonin were validated in vivo using arthritis scores and histopathological evaluation of collagen-induced arthritis mice. RESULTS Wogonin inhibited the migration and invasion of MH7A cells, reduced the production of TNF-α, IL-1β, IL-6, MMP-3 and MMP-9, and increased the expression of IL-10. Moreover, wogonin also inhibited the myofibrillar differentiation of MH7A cells, increased the expression of E-cadherin (E-Cad) and decreased the expression of α-smooth muscle actin (α-SMA). In addition, wogonin treatment effectively ameliorated joint destruction in CIA mice. Further molecular mechanism studies showed that wogonin treatment significantly inhibited the activation of PI3K/AKT/NF-κB signaling pathway in TNF-α-induced arthritic FLSs. CONCLUSION Wogonin effectively inhibits migration, invasion and pro-inflammatory cytokine production of RA fibroblast-like synoviocytes through the PI3K/AKT/NF-κB pathway, and thus wogonin, as a natural flavonoid, has great potential for treating RA.

PLoS One 2024; 19:e0299450.

Abstract
OBJECTIVES Compared to conventional disease-modifying antirheumatic drugs (DMARDs), biological DMARDs demonstrate superior efficacy but come with higher costs and increased infection risks. The ability to stop and resume biological DMARD treatment while maintaining remission would significantly alleviate these barriers and anxieties. The objective of this study was to identify biomarkers that can predict an imminent relapse, hopefully enabling the timely resumption of biological DMARDs before relapse occurs. METHODS Forty patients with rheumatoid arthritis who had been in remission for more than 12 months were included in the study. The patients discontinued their biological DMARD treatment and were monitored monthly for the next 24 months. Out of the 40 patients, 14 (35%) remained in remission at the end of the 24-month period, while 26 (65%) experienced relapses at different time points. Among the relapse cases, 13 patients experienced early relapse within 6 months, and another 13 patients had late relapse between 6 months and 24 months. Seventy-three cytokines in the sera collected longitudinally from the 13 patients with late relapse were measured by multiplex immunoassay. Using cytokines at two time points, immediately after withdrawal and just before relapse, volcano plot and area under the receiver operating characteristic curves (AUC) were drawn to select cytokines that distinguished imminent relapse. Univariate and multivariate logistic regression analyses were used for the imminent relapse prediction model. RESULTS IL-6, IL-29, MMP-3, and thymic stromal lymphopoietin (TSLP) were selected as potential biomarkers for imminent relapse prediction. All four cytokines were upregulated at imminent relapse time point. Univariate and multivariate logistic regression showed that a combination model with IL-6, MMP-3, and TSLP yielded an AUC of 0.828 as top predictors of imminent relapse. CONCLUSIONS This methodology allows for the prediction of imminent relapse while patients are in remission, potentially enabling the implementation of on- and off-treatments while maintaining remission. It also helps alleviate patient anxiety regarding the high cost and infection risks associated with biological DMARDs, which are the main obstacles to benefiting from their superb efficacy.

Abstract
INTRODUCTION The study aimed to optimize medical care for elderly patients with rheumatoid arthritis (RA) by examining the 3-year continuation rate of different molecular targeted therapies across age groups in Japan, which has a significant elderly population. METHODS The study included patients with RA who started molecular targeted therapies between 2013 and 2019 and divided them into three age groups. The primary outcome was to assess the 3-year continuation rate of each drug and analyze reasons for treatment discontinuation using inverse probability of treatment weighting. RESULTS Among 2292 patients analyzed, tumor necrosis factor (TNF) inhibitors were most commonly used in those younger than 65 years of age (43.5%), while Janus kinase (JAK) inhibitors were also utilized (17.1%). In contrast, JAK inhibitors were less frequently used in patients aged 75 years and older (7.8%), with cytotoxic T lymphocyte antigen 4 immunoglobulin fusion proteins (CTLA4-Ig) being the most common (39.2%). JAK inhibitors and anti-interleukin-6 receptor (IL-6R) antibodies had higher continuation rates than other drugs in patients under 65 years (p < 0.001). For those aged 65-74 years, JAK inhibitors and CTLA4-Ig had higher continuation rates (p < 0.001), while among those aged 75 years and older, CTLA4-Ig and IL-6R antibodies had higher continuation rates (p < 0.001). Inadequate efficacy was the main reason for discontinuation in all age groups, while infection leading to discontinuation increased with age. CONCLUSIONS The study highlights the need to consider different age groups separately in elderly RA care. Among patients aged 75 years and older, abatacept and anti-IL-6R antibodies showed the highest continuation rates, suggesting their potential suitability and efficacy for this specific age cohort.

Abstract
Janus kinase inhibitors (JAKis) are the most recent new drug class to arrive to the market for rheumatoid arthritis (RA) treatment. While they have proven to be a very effective treatment option, there remains significant concern regarding the risk of cardiovascular events, thrombosis and malignancy, particularly given the findings of the post-marketing ORAL Surveillance study and FDA black box warnings. This article reviews the key findings of the most impactful cohort of studies and registry data since ORAL Surveillance. It also evaluates the role of JAKis in practice and offers guidance on risk stratifying patients and determining their suitability for a JAKi.

Abstract
OBJECTIVE The most used drug for the treatment of rheumatoid arthritis (RA) remains methotrexate (MTX). Unfortunately, up to 50% of patients do not achieve a clinically adequate outcome. Here we study whether the gut microbiota patterns can aid in the prediction of MTX efficacy for RA. METHOD To dissect gut microbiome profiles of RA patients (n = 145), 16S rRNA gene sequencing was performed. Dirichlet multinomial mixture (DMM) clustering was used to identify enterotypes at genus level. The relationships between enterotypes and clinical measures (such as lymphocyte subsets and cytokines detected by flow cytometry) were explored. Then, enterotype stability was evaluated by the stratification of the RA patient cohort (n = 66) in Shanghai, China, using the same method. Finally, the enterotype-based gut microbial human index classifier was applied to another independent RA patient cohort (n = 27) to identify the factors associated with MTX clinical response. RESULTS Our analysis revealed that the RA patients always displayed two different dysbiotic microbiota patterns: RA E1 comprised predominantly Prevotella and RA E2 comprised predominantly Bacteroides. Among all of the lymphocyte subsets and cytokines, only the number of CD8+ T cells showed a significant difference between RA E1 and RA E2. These results were validated in the RA patient cohort in Shanghai, China. Significant associations of RA E1 with clinical response to subsequent MTX treatment were confirmed by another independent RA patient cohort. CONCLUSION Together, the enterotype-based gut microbial human index (EGMI) classifier was useful to precisely and effectively identify enterotypes of individual RA patients, which could effectively evaluate MTX clinical responses.

Abstract
Abstract
Background
Methotrexate (MTX) is an anchor drug used for the treatment of rheumatoid arthritis (RA); hence, understanding the reasons for MTX discontinuation in RA can help improve its treatment. Therefore, this study aimed to investigate the reasons for MTX discontinuation and to identify future challenges in RA treatment regarding the discontinuation and resumption of MTX treatment.
Results
MTX administration was discontinued in 771 patients with RA. The reasons for MTX discontinuation were as follows: (1) infectious diseases (20.0%), (2) malignancy (14.1%), and (3) respiratory problems (10.2%). Some patients did not resume MTX therapy even after the infections were cured. Liver dysfunction (8.0%) did not improve with MTX discontinuation and was often associated with fatty liver disease. In addition to adverse events, MTX discontinuation was due to patient preference (4.3%), planning for pregnancy (5.1%), invalidity (5.7%), remission (5.6%), remission with biologics (4.7%), old age (2.6%), and poor compliance (1.6%).
Conclusions
This study revealed diverse reasons for the discontinuation of MTX; there are cases in which MTX is discontinued but should be considered for resumption. Furthermore, issues such as the indications for MTX discontinuation should still be debated, and multicenter evidence must be collected and examined in future studies.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) pathogenesis is driven by a complex network of proinflammatory cytokines, among which interleukin-6 (IL-6) plays a key role in inducing and perpetuating chronic inflammation. Targeting the IL-6 pathway has shown to be an invaluable treatment strategy, as demonstrated by the results accrued in the last decade with the first IL-6 inhibitor, tocilizumab. More recently, a second monoclonal antibody blocking IL-6, sarilumab, has enriched our armamentarium by proving outstanding efficacy in RA treatment. AREAS COVERED After exploring the IL-6 pathway under physiological conditions and in the RA pathogenesis, in this review we discuss the pharmacologic properties of sarilumab and the clinical trials that constitute the sarilumab development program and have enabled its licensed application. EXPERT OPINION Results from clinical trials confirmed the efficacy and safety of sarilumab for the treatment of RA, similar to its precursor tocilizumab. Blocking IL-6 pathway results in comprehensive control of the disease, from both physician's and patient's perspective, and of RA comorbidities and extra-articular manifestations which are largely IL-6 driven. Finally, the proven efficacy of sarilumab as monotherapy arises the drug as a required therapeutic alternative considering the large proportion of patients intolerant or inadequate to receive conventional synthetic disease-modifying drugs (csDMARDs).

Abstract
Background Severe coronavirus disease 2019 (COVID -19) has led to a rapid increase in mortality worldwide. Rheumatoid arthritis (RA) was a high-risk factor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, whereas the molecular mechanisms underlying RA and CVOID-19 are not well understood. The objectives of this study were to analyze potential molecular mechanisms and identify potential drugs for the treatment of COVID-19 and RA using bioinformatics and a systems biology approach. Methods Two Differentially expressed genes (DEGs) sets extracted from GSE171110 and GSE1775544 datasets were intersected to generate common DEGs, which were used for functional enrichment, pathway analysis, and candidate drugs analysis. Results A total of 103 common DEGs were identified in the two datasets between RA and COVID-19. A protein-protein interaction (PPI) was constructed using various combinatorial statistical methods and bioinformatics tools. Subsequently, hub genes and essential modules were identified from the PPI network. In addition, we performed functional analysis and pathway analysis under ontological conditions and found that there was common association between RA and progression of COVID-19 infection. Finally, transcription factor-gene interactions, protein-drug interactions, and DEGs-miRNAs coregulatory networks with common DEGs were also identified in the datasets. Conclusion We successfully identified the top 10 hub genes that could serve as novel targeted therapy for COVID-19 and screened out some potential drugs useful for COVID-19 patients with RA.

The Pretreatment Gut Microbiome Is Associated With Lack of Response to Methotrexate in New-Onset Rheumatoid Arthritis. Arthritis Rheumatol 2021; 73:931-942. [PMID: 33314800 PMCID: PMC11293279 DOI: 10.1002/art.41622] [Citation(s) in RCA: 69] [Impact Index Per Article: 23.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 11/15/2020] [Accepted: 12/02/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVE Although oral methotrexate (MTX) remains the anchor drug for rheumatoid arthritis (RA), up to 50% of patients do not achieve a clinically adequate outcome. In addition, there is a lack of prognostic tools for treatment response prior to drug initiation. This study was undertaken to investigate whether interindividual differences in the human gut microbiome can aid in the prediction of MTX efficacy in new-onset RA. METHODS We performed 16S ribosomal RNA gene and shotgun metagenomic sequencing on the baseline gut microbiomes of drug-naive patients with new-onset RA (n = 26). Results were validated in an additional independent cohort (n = 21). To gain insight into potential microbial mechanisms, we conducted ex vivo experiments coupled with metabolomics analysis to evaluate the association between microbiome-driven MTX depletion and clinical response. RESULTS Our analysis revealed significant associations of the abundance of gut bacterial taxa and their genes with future clinical response (q < 0.05), including orthologs related to purine and MTX metabolism. Machine learning techniques were applied to the metagenomic data, resulting in a microbiome-based model that predicted lack of response to MTX in an independent group of patients. Finally, MTX levels remaining after ex vivo incubation with distal gut samples from pretreatment RA patients significantly correlated with the magnitude of future clinical response, suggesting a possible direct effect of the gut microbiome on MTX metabolism and treatment outcomes. CONCLUSION Taken together, these findings are the first step toward predicting lack of response to oral MTX in patients with new-onset RA and support the value of the gut microbiome as a possible prognostic tool and as a potential target in RA therapeutics.

Abstract
SARS-CoV-2 infection is a major concern and a new threat to immunocompromised patients. Patients with chronic inflammatory bowel diseases (IBDs) are at increased risk of infections, in particular when they have active disease and are on immunosuppressive treatment. The purpose of this study was to assess the clinical, biological and radiological features of three patients with COVID-19 associated with chronic IBD as well as their management and outcomes. The study was conducted at the Hassan II University Teaching Hospital in Fes, Morocco over a 3-month period. We assessed all patients with disease onset. All patients had mild symptoms or were asymptomatic. No changes or delays in treatment regimens occurred and none of patients developed severe COVID-19. Reverse transcription polymerase chain reaction (RT-PCR) test results were positive in all patients. Radiological examinations were conducted. Chest scanner showed ground-glass opacities in one case. Treatment was based on hydroxychloroquine with azithromycin. Outcome was good in all cases. This preliminary report suggests that patients with chronic IBD aren't at higher risk of developing COVID-19 compared to the general population.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic autoimmune disease, whose natural course has been deeply modified thanks to the development of new therapeutic approaches. The Janus kinase inhibitors (Jakinibs) represent the newest class of drugs introduced for treating RA. Among these, Filgotinib (FIL) has been developed as Janus kinase1 (JAK1) selective inhibitor, specifically targeting key pro-inflammatory mediators in RA pathogenesis. AREAS COVERED This narrative review provides an overview on FIL as new therapeutic approach for RA, with focus on its pharmacological properties, clinical efficacy, and safety profile. The following electronic databases were adopted for the study search: PubMed, Google Scholar, ClinicalTrials.gov and Abstract archive from the American College of Rheumatology and the European Alliance of Associations for Rheumatology. EXPERT OPINION The phase II and phase III randomized controlled trials (RCTs) performed so far and their long-term extensions showed a comparable clinical efficacy of FIL to biologic treatments, with an acceptable safety profile. Thanks to these data, FIL was approved in Europe and Japan for the treatment of active RA, increasing the spectrum of therapeutic approaches and improving the possibility of a more tailored therapeutic strategy. Real-life data and head-to-head clinical trials will be needed to confirm its efficacy and safety.

Abstract
Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disease that leads to joint destruction and disability. Despite a significant progress in administration of biological agents for RA patients, there is still a need for improved therapy. Intravenous immunoglobulins (IVIG), a pooled polyspecific immunoglobulin (Ig)G extracted from 5000 to 20 000 healthy subjects, showed beneficial therapeutic effect in patients with immune deficiency, sepsis and autoimmune diseases. The current study aimed to investigate the beneficial effect of treatment with IVIG in established collagen-induced arthritis in DBA/1j mice. Murine arthritis was induced in DBA/1j mice. Treatment with IVIG began when the disease was established. The clinical score was followed twice a week until day 48. The mice were bled for plasma and the paws were hematoxylin and eosin (H&E)-stained. Cytokine profile in the plasma was analyzed by Luminex technology and titers of circulating anti-collagen antibodies in the plasma was tested by enzyme-linked immunosorbent assay. Our results show that treatment with IVIG in murine significantly reduced the clinical arthritis score (P < 0·001). Moreover, mode of action showed that IVIG significantly reduced circulating levels of inflammatory cytokines [interferon (IFN)-γ, interleukin (IL)-1β, IL-17, IL-6, tumor necrosis factor (TNF)-α, P < 0·001], inhibiting anti-collagen antibodies (P < 0·001) in the plasma of collagen-induced arthritis mice. Importantly, histopathological examination revealed that IVIG treatment prevented the migration of inflammatory immune cells into the cartilage and synovium, reduced the extent of joint damage and preserved joint architecture. Our results proved for the first time the valuable anti-inflammatory treatment of IVIG in experimental RA. We propose IVIG therapy for a subgroup of patients with rheumatologically related diseases.

Abstract
Rheumatoid arthritis is a chronic inflammatory destructive disorder that affects the joints, muscles, and tendons accompanying various extra-articular manifestations. Traditional disease-modifying anti-rheumatic drugs (DMARDs) represent the basic treatment for rheumatoid arthritis. Over the last 20 years, biologic DMARDs (tumor necrosis factor inhibitors, interleukin-1 inhibitors, interleukin-6 inhibitors, T cell inhibitors, and B cell inhibitors) have been widely used as a novel class of DMARDs that have efficacy and efficiency. Discovery of the underlying pathogenesis of autoimmune disease enables us to develop new target therapies such as a Janus kinase (JAK) inhibitor. Activated JAK is known to activate signal transducers as well as activators of transcription (STAT) signaling. A JAK inhibitor is a type of medication that functions by inhibiting the JAK-STAT signaling pathway. In addition, it is easy to take a JAK inhibitor orally. In Korea, several JAK inhibitors have been approved. This review describes the types of JAK inhibitors, recommended doses, side effects, and updated European Alliance of Associations for Rheumatology guidelines. Clinicians should more often consider JAK inhibitors in the treatment of refractory rheumatoid arthritis in current rheumatology clinics

Abstract
Background: We investigated whether taking methotrexate (MTX) is associated with a lower risk of new-onset cancers in patients with rheumatoid arthritis (RA). Methods: We conducted a 12-year retrospective cohort study from a population-based National Health Insurance Research Database in Taiwan. A total of 21,699 patients with newly diagnosed RA were enrolled during 2000–2009. The overall cancer rate was compared between 10,352 new users of MTX and 11,347 non-users. We used the WHO Defined Daily Dose (DDD) as a tool to assess drug exposure. Cox proportional hazard regression models were used to estimate the hazard ratio (HR) of disease after controlling for demographics and other comorbidities. Results: After adjusting for age, sex, cancer-related comorbidities, and RA-combined medication, the HR of cancer risk was 0.87 (95% CI = 0.74–1.02) for the MTX user group compared with the MTX non-user group. The cumulative incidence of cancer in the MTX non-user group was significantly higher than that of the MTX user group (log-rank test p < 0.001). In the low accumulative dose group [cumulative dose <1125 mg, cumulative defined daily dose (cDDD) <450], the HR of cancer risk for MTX users was 1.20 (95% CI = 1.01–1.42) compared with the MTX-non-user group. However, the adjusted HR of cancer risk was reduced to 0.66 (95% CI = 0.49–0.87) in MTX middle-dose users (cumulative dose 1125–2250 mg, cDDD: 450–899) and 0.33 (95% CI = 0.23–0.48) for the MTX high-dose group (cumulative dose ⩾2250 mg, cDDD ⩾900), respectively (p for trend < 0.0001). Conclusion: MTX at middle and high accumulative doses might be associated with lower risk of new-onset cancers in patients with RA.

Abstract
Janus kinase (JAK) Inhibitors are the latest drug class of disease-modifying medication to emerge for the treatment of rheumatoid arthritis (RA). They are a small molecule-targeted treatment and are the first oral option to compare favourably to existing biologic disease-modifying anti-rheumatic drugs (DMARDs). Tofacitinib, baricitinib and upadacitinib are the first 3 JAK inhibitors to become commercially available in the field and are the core focus of this review. To date, they have demonstrated comparable efficacy to tumour necrosis factor (TNF) inhibitors in terms of American College of Rheumatology (ACR) response rates and disease activity (DAS28) scores with similar cost to the benchmark adalimumab. This narrative review article aims to synthesise and distil the key available trial data on JAK inhibitor efficacy and safety, along with their place in the ACR and European League Against Rheumatism (EULAR) guidelines for RA. The novel mechanism of action of the JAK/STAT pathway is highlighted along with the potential effects of modulating each pathway. The rapid onset of action, role in attenuation of central pain processing and effect on structural damage and radiographic progression are also all examined in detail. We also explore the latest meta-analyses and comparative performance of each of the 3 available JAKs in an effort to determine which is most efficacious and which has the most favourable safety profile. Post marketing concerns regarding thromboembolism risk and herpes zoster infection are also discussed. Additionally, we review the cost-benefit analyses of the available JAK inhibitors and address some of the pharmacoeconomic considerations for real-world practice in the UK and US by detailing the raw acquisition cost and the value they provide in comparison to the benchmark biologic adalimumab and the anchor DMARD methotrexate.

Abstract
Rheumatoid arthritis (RA) is a chronic, debilitating autoimmune disorder involving inflammation and progressive destruction of the joints, affecting up to 1% of the population. The majority of patients with RA have one or more comorbid conditions, the most common being cardiovascular disease, osteoporosis, and depression, the presence of which are associated with poorer clinical outcomes and lower health-related quality of life. RA pathogenesis is driven by a complex network of proinflammatory cells and cytokines, and of these, interleukin-6 (IL-6) plays a key role in the chronic inflammation associated with RA. Through cell signaling that can be initiated by both membrane-bound and soluble forms of its receptor, IL-6 acts both locally to promote joint inflammation and destruction, and in the circulation to mediate extra-articular manifestations of RA, including pain, fatigue, morning stiffness, anemia, and weight loss. This narrative review describes the role of IL-6 in the pathogenesis of RA, its comorbidities, and extra-articular systemic manifestations, and examines the effects of the IL-6 receptor inhibitors sarilumab and tocilizumab on clinical endpoints of RA, patient-reported outcomes, and common comorbidities and extra-articular manifestations.

Abstract
So far, available evidence suggests that patients with inflammatory bowel disease (IBD) are not at greater risk for developing COVID-19 infection. In regard to patients with IBD remission: 5-aminosalycylates (5-ASAs) do not increase the risk for infection and should be continued. There is no need to suspend them or lower the dose. Immunomodulating drugs, such as thiopurines and methotrexate, should be continued, without modifying doses (even in patients with positive SARS-CoV-2 infection). No type of biologic therapy should be suspended, unless there are signs of COVID-19. Regarding patients with IBD activity: the oral and/or topical 5-ASA dose should be optimized in cases of disease relapse. Budesonide MMX should be considered in cases of mild-to-moderate activity, to avoid systemic steroid use. Systemic steroids should be avoided whenever possible because doses above 20mg per day have an immunosuppressive effect, which could increase susceptibility to any type of infection, including COVID-19. The combined use of thiopurines with steroids and/or tumor necrosis factor (TNF) monoclonal antibodies should also be avoided because those combinations can increase the risk for infections, including COVID-19. Finally, biologic treatment with anti-TNF-alpha agents or any other mechanism of action, such as anti-integrins or anti-interleukins, should be suspended if patients become infected with SARS-CoV-2. The drugs can be restarted once the infectious process is resolved.

So far, available evidence suggests that patients with inflammatory bowel disease (IBD) are not at greater risk for developing COVID-19 infection. In regard to patients with IBD remission: 5-aminosalycylates (5-ASAs) do not increase the risk for infection and should be continued. There is no need to suspend them or lower the dose. Immunomodulating drugs, such as thiopurines and methotrexate, should be continued, without modifying doses (even in patients with positive SARS-CoV-2 infection). No type of biologic therapy should be suspended, unless there are signs of COVID-19. Regarding patients with IBD activity: the oral and/or topical 5-ASA dose should be optimized in cases of disease relapse. Budesonide MMX should be considered in cases of mild-to-moderate activity, to avoid systemic steroid use. Systemic steroids should be avoided whenever possible because doses above 20 mg per day have an immunosuppressive effect, which could increase susceptibility to any type of infection, including COVID-19. The combined use of thiopurines with steroids and/or tumor necrosis factor (TNF) monoclonal antibodies should also be avoided because those combinations can increase the risk for infections, including COVID-19. Finally, biologic treatment with anti-TNF-alpha agents or any other mechanism of action, such as anti-integrins or anti-interleukins, should be suspended if patients become infected with SARS-CoV-2. The drugs can be restarted once the infectious process is resolved.

Abstract
Introduction/objectives The current 2019 novel coronavirus outbreak is continuing to spread rapidly despite all efforts. Patients with rheumatic disease may have higher levels of anxiety due to their disease characteristics and medications. The web-based platforms are widely used sources for gaining medical information. YouTube presents a wide range of medical information, but there are concerns on its quality. Therefore, we aimed to evaluate the quality of the YouTube videos about COVID-19 and rheumatic diseases link. Method This is a descriptive study. A total of 360 videos listed by the YouTube search engine (www.youtube.com) in response to six search terms were evaluated. The Global Quality Scale (GQS) was performed to evaluate video quality. Three groups were formed according to GQS scores: high quality, moderate quality, and low quality. Video parameters were compared between these groups. Results After the exclusion criteria, 46 videos were reviewed. Of the videos, 41.4% (n = 19) were of high-quality group, 21.7% (n = 10) were moderate-quality group, and 36.9% (n = 17) were of low-quality group. Significant difference was detected between the quality groups in terms of views per day (p = 0.004). No significant difference was detected in comments per day (p = 0.139) and like ratio (p = 0.232). Conclusions Besides high-quality videos, there were substantially low-quality videos that could cause misleading information to spread rapidly during the pandemic. Videos from trustworthy sources such as universities, academics, and physicians should be kept in the foreground.Key Points •Web-based platforms have become an important source of health-related information. One of the most important online sources is YouTube because it is easy accessible and free. •Of the videos evaluating the link between COVID-19 and rheumatic diseases, 41.4% (n = 19) were of high quality. •The main sources of high-quality videos were academics/universities and physicians. •The most frequently discussed topics in videos were the place of hydroxychloroquine in the treatment of COVID-19 and whether to continue the use of existing rheumatological drugs. |

Abstract
The coronavirus disease 2019 (COVID-19), the result of an infection with the new virus, SARS-CoV-2, is rapidly spreading worldwide. It is largely unknown whether the occurrence of COVID-19 in patients with rheumatic immune diseases has some specific manifestations, or makes them more prone to rapidly progress into severe COVID-19. In this case report, we describe the clinical features of 5 rheumatic immune disease patients with the concomitant presence of COVID-19. Amongst these patients, 4 had rheumatoid arthritis (RA) and 1 had systemic sclerosis (SSc). Two patients had a history of close contact with a COVID-19 patient. The age of the patients ranged between 51 and 79 years. Fever (80%), cough (80%), dyspnea (40%), and fatigue (20%) were the most common presenting symptoms. Laboratory investigations revealed leukopenia and lymphopenia in 2 patients. In all the patients, chest computerized tomography (CT) revealed patchy ground glass opacities in the lungs. During the hospital stay, the condition of two patients remained the same (i.e., mild COVID-19), two patients progressed to the severe COVID-19, and one patient worsened to the critically ill COVID-19. These patients were treated with antiviral agents for COVID-19, antibiotics for secondary bacterial infections, and immunomodulatory agents for rheumatic immune diseases. All the patients responded well, were cured of COVID-19, and subsequently discharged.

Abstract
The outbreak of the new coronavirus infections COVID-19 in December 2019 in China has quickly become a global health emergency. Given the lack of specific anti-viral therapies, the current management of severe acute respiratory syndrome coronaviruses (SARS-CoV-2) is mainly supportive, even though several compounds are now under investigation for the treatment of this life-threatening disease. COVID-19 pandemic is certainly conditioning the treatment strategy of a complex disorder as rheumatoid arthritis (RA), whose infectious risk is increased compared to the general population because of an overall impairment of immune system typical of autoimmune diseases combined with the iatrogenic effect generated by corticosteroids and immunosuppressive drugs. However, the increasing knowledge about the pathophysiology of SARS-CoV-2 infection is leading to consider some anti-rheumatic drugs as potential treatment options for the management of COVID-19. In this review we will critically analyse the evidences on either positive or negative effect of drugs commonly used to treat RA in this particular scenario, in order to optimize the current approach to RA patients.

Abstract
In the past three decades, extraordinary advances have been made in the understanding of the pathogenesis of, and treatment options for, inflammatory arthritides, including rheumatoid arthritis and spondyloarthritis. The use of methotrexate and subsequently biologic therapies (such as TNF inhibitors, among others) and oral small molecules have substantially improved clinical outcomes for many patients with inflammatory arthritis; for others, however, these agents do not substantially improve their symptoms. The emerging field of pharmacomicrobiomics, which investigates the effect of variations within the human gut microbiome on drugs, has already provided important insights into these therapeutics. Pharmacomicrobiomic studies have demonstrated that human gut microorganisms and their enzymatic products can affect the bioavailability, clinical efficacy and toxicity of a wide array of drugs through direct and indirect mechanisms. This discipline promises to facilitate the advent of microbiome-based precision medicine approaches in inflammatory arthritis, including strategies for predicting response to treatment and for modulating the microbiome to improve response to therapy or reduce drug toxicity.

Abstract
Rheumatoid arthritis (RA) is a systemic, autoimmune disease that affects joints and extra-articular structures. In the last decade, the management of this chronic disease has dramatically changed with the introduction of several targeted mechanisms of action, such as tumor necrosis factor-α inhibition, T-cell costimulation inhibition, B-cell depletion, interleukin-6 blockade, and Janus kinase inhibition. Beyond its well-known hematopoietic role on the proliferation and differentiation of myeloid cells, granulocyte-monocyte colony-stimulating factor (GM-CSF) is a proinflammatory mediator acting as a cytokine, with a proven pathogenetic role in autoimmune disorders such as RA. In vitro studies clearly demonstrated the effect of GM-CSF in the communication between resident tissue cells and activated macrophages at chronic inflammation sites, and confirmed the elevation of GM-CSF levels in inflamed synovial tissue of RA subjects compared with healthy controls. Moreover, a pivotal role of GM-CSF in the perception of pain has been clearly confirmed. Therefore, blockade of the GM-CSF pathway by monoclonal antibodies directed against the cytokine itself or its receptor has been investigated in refractory RA patients. Overall, the safety profile of GM-CSF inhibitors seems to be very favorable, with a particularly low incidence of infectious complications. The efficacy of this new mechanism of action is comparable with main competitors, even though the response rates reported in phase II randomized controlled trials (RCTs) appear to be numerically lower than the response rates observed with other biological disease-modifying antirheumatic drugs already licensed for RA. Mainly because of this reason, nowadays the development program of most GM-CSF blockers for RA has been discontinued, with the exception of otilimab, which is under evaluation in two phase III RCTs with a head-to head non-inferiority design against tofacitinib. These studies will likely be useful for better defining the potential role of GM-CSF inhibition in the therapeutic algorithm of RA. On the other hand, the potential role of GM-CSF blockade in the treatment of other rheumatic diseases is now under investigation. Phase II trials are ongoing with the aim of evaluating mavrilimumab for the treatment of giant cell arteritis, and namilumab for the treatment of spondyloarthritis. Moreover, GM-CSF inhibitors have been tested in osteoarthritis and diffuse subtype of systemic sclerosis. This review aims to describe in detail the available evidence on the GM-CSF blocking pathway in RA management, paving the way to a possible alternative treatment for RA patients. Novel insights regarding the potential use of GM-CSF blockers for alternative indications will be also addressed.

Abstract
Rheumatoid arthritis (RA) is the most common autoimmune rheumatic disease, in which an epigenetic implication in the disease etiopathogenesis has been noted. Here in this meta-analysis, we attempted to investigate the pooled association of methylenetetrahydrofolate reductase (MTHFR) gene C677T and A1298C polymorphisms and susceptibility to RA risk. A systematic search was performed in the main databases, including MEDLINE and Scopus to search for studies assessing the association between MTHFR gene C677T and A1298C polymorphisms and the risk of RA prior to December 2019. In this meta-analysis, 15 studies with 2165 patients and 1751 healthy controls for C677T SNP and 14 studies containing 2021 patients and 1760 healthy controls for A1298C SNP were included. A significant positive association between C677T SNP and RA risk was recognized in the dominant, recessive, and allelic model, but not TT and CT genotypes. The results indicated that the risk of RA in African population was increased under all genotype models while these results were repeated in Asian population just for recessive model, allelic model, and TT genotype. Moreover, the analysis of A1298C SNP demonstrated a significant association in overall population according to only the recessive model and CC genotype. Subgroup analysis according to the genotyping method indicated that RFLP-PCR method could impress the results of association between MTHFR gene A1298C and C677T SNPs and RA risk. The outcome of this meta-analysis indicated that MTHFR gene C677T SNP was much possibly be associated with RA risk.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease that, if untreated, can lead to disability and reduce the life expectancy of affected patients. Over the last two decades the improvement of knowledge of the pathogenetic mechanisms leading to the development of the disease has profoundly changed the treatment strategies of RA through the development of biotechnological drugs (bDMARDs) directed towards specific pro-inflammatory targets involved in the RA network. To date, the therapeutic armamentarium for RA includes ten bDMARDs able to produce the depletion B-cells, the blockade of three different pro-inflammatory cytokines (tumour necrosis factor alpha, interleukin-6 and interleukin-1), or the inhibition of T-cell co-stimulation. The introduction of these new compounds has dramatically improved outcomes in the short and long term, although still a significant proportion of patients are unable to reach or maintain the treatment target over time. The identification of the fundamental role of Janus kinases in the process of transduction of the inflammatory signal within the immune cells has recently provided the opportunity to use the new pharmacological class of small molecules for the therapy of RA, further increasing the number of treatment options. In this review the PROS and CONS of these two drug classes will be discussed, trying to provide the evidence currently available to make the right choice based on the analysis of the efficacy and safety profile of the different drugs on the market and close to marketing.

Abstract
Introduction: Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease, which affects joints as well as extra-articular tissues. In the last decades, increasing targeted therapeutic options dramatically improved RA management by doubling the rate of patients achieving clinical remission. Currently, there is a need for management strategies aimed at limiting treatment-related adverse events and costs in good responders.Areas covered: Data on de-escalation of biologic drugs (especially for anti-TNF agents) are mainly available from post-hoc analyses of randomized controlled trials and from registry-based observational studies. This narrative review illustrates the rationales for dose tapering and expands to provide an overview of the efficacy of the different available strategies for reducing the exposure to biologic drugs in patients achieving a sustained clinical response. Selected studies are discussed as illustrative examples.Expert opinion: Withdrawal of biologic therapy might be attempted in limited patients with very early RA; conversely, established RA is more suitably managed with a progressive decrease of drug regimen, by either dose reduction or injection/infusion spacing. Further studies investigating potential factors predicting post-tapering disease relapse are warranted, in order to better identify the best candidates for a decreased-dose approach.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease characterized by joint involvement, extra-articular manifestations, comorbidities, and increased mortality. In the last few decades, the management of RA has been dramatically improved by the introduction of a treat-to-target approach aiming to prevent joint damage progression. Moreover, the increasing knowledge about disease pathogenesis allowed the development of a new drug class of biologic agents targeted on immune cells and proinflammatory cytokines involved in RA network. Despite the introduction of several targeted drugs, a significant proportion of RA patients still fail to achieve the clinical target; so, more recently the focus of research has been shifted toward the inhibition of kinases involved in the transduction of the inflammatory signal into immune cells. In particular, two Janus kinase (JAK) inhibitors, baricitinib and tofacitinib, have been licensed for the treatment of RA as a consequence of a very favorable profile observed in randomized controlled trials (RCTs) conducted across different RA subpopulations. Both these new compounds are active on the majority of four JAK family members (JAK1, JAK2, JAK3, and TYK2), whereas the most recent emerging approach is directed toward the development of JAK1 selective inhibitors (upadacitinib and filgotinib) with the aim to improve the safety profile by minimizing the effects on JAK3 and, especially, JAK2. In this narrative review, we discuss the rationale for JAK inhibition in RA, with a special focus on the role of JAK1 selective blockade and a detailed description of available data from the results of clinical trials on upadacitinib and filgotinib.

Abstract
Introduction: Rheumatoid arthritis (RA) is a chronic, systemic, autoimmune disease, which affects joints and extra-articular structures. Nowadays, the armamentarium of therapeutic options is progressively expanding and embraces several mechanisms of action: TNF inhibition, B-cell depletion, T-cell co-stimulation inhibition, IL-6 blockade, and JAK-inhibition. Granulocyte-Monocyte-Colony-Stimulating-Factor (GM-CSF) is a mediator acting as a cytokine with a proven pathogenetic role in RA, providing a potential alternative target for the management of the disease. Mavrilimumab is a monoclonal antibody against GM-CSF receptor, which has been successfully tested in RA patients. Areas covered: Beginning with a description of the preclinical evidence and the rationale for GM-CSF blockade in RA, this review will provide a wide overview of mavrilimumab efficacy and safety profile by analyzing phase I/II RCTs conducted in patients with moderate to severe RA. Expert opinion: According to the promising results from phase I-II RCTs, mavrilimumab could be considered as an additional therapeutic option for RA patients multi-resistant to the available targeted drugs. However, the optimal dose and the profile of this new drug should be confirmed in phase III RCTs before the marketing.

Abstract
INTRODUCTION There are over 40,000 people living in Ireland with inflammatory arthritis (IA), a condition that is potentially destructive in nature and can have personal, social and economic consequences. Although we have witnessed dramatic changes in the treatment of IA in the last two decades, methotrexate (MTX) remains the first-line treatment for patients with a diagnosis of IA. Despite the fact that MTX is so commonly prescribed, there is a lack of educational materials both for healthcare professionals (HCPs) and patients. The aim of the present study was to develop a suite of MTX material for patients. METHODS A comprehensive literature review of MTX (evidence, educational materials and practice guidelines) in the treatment of IA was undertaken. The content of the documents was developed, and the format and structure of the documents were agreed. A tailored patient educational guide, information/monitoring booklet and alert card were designed to address the lack of educational materials for this condition. A national pilot study of the documents was conducted (a postal questionnaire for patients and electronic survey for clinical nurse specialists). Results and recommendations were incorporated into the final documents. These documents were also incorporated into the National Clinical Care Programme-rheumatology-methotrexate pathway. RESULTS A 26-page evidence-based educational guide was produced to support the HCP in educating patients taking MTX, in conjunction with a patient information/monitoring booklet and alert card to support the patient. CONCLUSIONS These documents are now widely available and used in clinical practice in Ireland, providing patients with standardized, evidence-based information about MTX.

Association of Baseline Peptidylarginine Deiminase 4 Autoantibodies With Favorable Response to Treatment Escalation in Rheumatoid Arthritis. Arthritis Rheumatol 2019; 71:696-702.

Abstract
OBJECTIVE To determine if the baseline presence of autoantibodies to peptidylarginine deiminase 4 (PAD4) predicts therapeutic response to biologic and conventional disease-modifying antirheumatic drugs (DMARDs) in patients with rheumatoid arthritis (RA) in whom methotrexate (MTX) monotherapy was unsuccessful. METHODS Baseline serum from 282 RA patients in whom MTX monotherapy was unsuccessful was screened for the presence of anti-PAD4 antibodies by immunoprecipitation. Clinical response to either triple DMARD (MTX, sulfasalazine, and hydroxychloroquine) or MTX/etanercept combination therapy was determined at 24 and 48 weeks post-treatment initiation. Disease activity was measured using the Disease Activity Score 28-joint assessment (DAS28), and erosive disease was quantified using the Sharp/van der Heijde scoring method. Generalized estimating equations (GEEs) were used to model the clinical responses to treatment in patients with and those without baseline anti-PAD4 antibodies. RESULTS Anti-PAD4 antibody positivity was associated with male sex, a history of never smoking, and anti-citrullinated protein antibodies. At baseline, patients with anti-PAD4 antibodies had longer disease duration and significantly more radiographic joint damage than anti-PAD4-negative patients, but did not differ in disease activity according to the DAS28. In unadjusted analyses and multivariable GEE models, patients with anti-PAD4 antibodies exhibited greater improvements in DAS28 (adjusted P = 0.02 and P = 0.008, respectively) and less radiographic progression (adjusted P = 0.01 and P = 0.002, respectively) compared to anti-PAD antibody-negative patients, independent of treatment received. CONCLUSION Although anti-PAD4 antibodies were associated with worse baseline radiographic joint damage, suggesting a history of active or undiagnosed disease, treatment escalation therapy was more effective in reducing disease activity and slowing the progression of joint damage in this patient subset.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by articular and systemic manifestations, such as anemia, fatigue, osteoporosis, and increased risk for cardiovascular diseases. The pathogenesis of RA is driven by a complex network of proinflammatory cytokines, with a pivotal role of IL-6 and tumor necrosis factor (TNF). The management of RA has been dramatically changed during the last years by the introduction of a treat-to-target approach aiming to achieve an acceptable disease control. Nowadays, TNF inhibitors (TNFis) are the most frequently prescribed class of biologic therapies, but the significant proportion of patients experiencing the failure of a TNFi led to the development of alternative therapeutic options targeted on different pathways. Considering the increasing number of targeted therapeutic options for RA, there is a growing interest in the identification of potential predictors of clinical response to each available mechanism of action, with the aim to drive the management of the disease toward a personalized approach according to the concept of precision medicine. Tocilizumab (TCZ) is the first humanized anti-IL-6 receptor subunit alpha (anti-IL-6R) monoclonal antibody approved for the treatment of RA refractory to methotrexate or TNFis. TCZ inhibits both the cis- and trans-signaling cascades involving the Janus kinase-signal transducer and the activator of transcription pathway, playing a crucial role in modulating not only joint inflammation but also the previously mentioned extra-articular manifestations and comorbidities of RA, such as fatigue, anemia, bone loss, depression, type 2 diabetes, and increased cardiovascular risk. In this review, moving from pathogenetic insights and evidence-based clinical data from randomized controlled trials and real-life observational studies, we will discuss the drivers for the selection of patient candidates to receive TCZ, in order to clarify the current positioning of this drug in the treatment algorithm of RA.

Abstract
Methotrexate (MTX) is used as an anchor disease-modifying anti-rheumatic drugs (DMARDs) in treating rheumatoid arthritis (RA) because of its potent efficacy and tolerability. MTX benefits a large number of RA patients but partially suffered from side effects. A variety of side effects can be associated with MTX when treating RA patients, from mild to severe or discontinuation of the treatment. In this report, we reviewed the possible side effects that MTX might cause from the most common gastrointestinal toxicity effects to less frequent malignant diseases. In order to achieve regimen with less side effects, the administration of MTX with appropriate dose and a careful pretreatment inspection is necessary. Further investigations are required when combining MTX with other drugs so as to enhance the efficacy and reduce side effects at the same time. The management of MTX treatment is also discussed to provide strategies for occurred side effects. Thus, this review will provide scholars with a comprehensive understanding the side effects of MTX administration by RA patients.

Helminths-based bi-functional molecule, tuftsin-phosphorylcholine (TPC), ameliorates an established murine arthritis. PLoS One 2018; 13:e0200615.

Abstract
A novel small molecule named tuftsin-phosphorylcholine (TPC), which is linked to the biological activity of helminths, was constructed. The current study address the effect of TPC treatment in established collagen-induced arthritis (CIA) mice and propose TPC bi-functional activity. TPC treatment was initiated when clinical score was 2 to 4. Arthritis scores in TPC treated mice were lower compared to mice treated with vehicle (P < 0.001). Joint staining showed normal joint structure in TPC-treated mice compared to control groups treated with phosphate buffered saline (PBS), phosphorylcholine, or tuftsin, which exhibited severely inflamed joints. TPC enhanced anti-inflammatory response due to increased IL-10 secretion, and reduced pro-inflammatory cytokine secretion (IL-1-β, IL-6, TNF-αP < 0.001). Furthermore, TPC therapy increased expansion of CD4+CD25+FOXP3+T regulatory cells and IL-10+CD5+CD1d+B regulatory cells. We propose that the immunomodulatory activity of TPC can be a result of a bi-specific activity of TPC: (a) The tuftsin part of the TPC shifts RAW macrophage cells from pro-inflammatory macrophages M1 to anti-inflammatory M2-secreting IL-10 (P < 0.001) through neuropilin-1 and (b) TPC significantly reduce mouse TLR4 expression via NFkB pathway by HEKTM cells (P < 0.02) via the phosphorylcholine site of the molecule. Our results indicate that TPC, significantly ameliorated established CIA by its immunomodulatory activity. These data could lead to a novel self bi-functional small molecule for treating patients with progressive RA.

Abstract
Antigen-specific tolerizing DNA vaccines are one of the most promising strategies for rheumatoid arthritis (RA) treatment. They act by inducing potent immune tolerance instead of generalized immunosuppression. Recently, we developed a novel antigen-specific tolerizing DNA vaccine pcDNA-CCOL2A1 coding for chicken type II collagen (CCII) and confirmed its potent therapeutic efficacy in an established rat model of collagen-induced arthritis (CIA). Here we report the prophylactic vaccination efficacy of a single 300 μg/kg dose of pcDNA-CCOL2A1 against CIA incidence, severity, and onset. CCOL2A1 transcripts were detected in the blood of CIA rats 14-42 days after intramuscular injection by 300 μg/kg pcDNA-CCOL2A1. The expression of CCOL2A1 transcripts increased quickly on day 21, peaked at day 28, and then gradually decreased thereafter. Importantly, a single prophylactic vaccination of pcDNA-CCOL2A1 14 days before CIA establishment significantly reduced CIA incidence and severity, deferred its onset, and was as efficacious as the current gold standard drug, methotrexate. The marked effects on CIA incidence and severity closely corresponded to the expression of CCOL2A1. Furthermore, prophylactic vaccination with pcDNA-CCOL2A1 markedly decreased serum content of anti-type II collagen (CII) immunoglobulin G (IgG) antibodies, induced Th1-to-Th2 and Tc1-to-Tc2 shifts, and decreased the percentages of CD4+CD29+ and Th17 T cells. Prophylactic vaccination with pcDNA-CCOL2A1 also downregulated various Th1 cytokines, while upregulating both the Th2-type cytokine interleukin-10 and the Th3-type cytokine transforming growth factor β. Our results indicate that the pcDNA-CCOL2A1 DNA vaccine acts as a highly efficient inducer of specific immunotolerance that could be a promising option for RA treatment in the near future.

Abstract
OBJECTIVE To evaluate the pattern of prescription and maintenance over time of concomitant methotrexate (MTX), and its impact on a 2-year clinical response in a cohort of rheumatoid arthritis (RA) patients treated with a first-line tumor necrosis factor alpha inhibitor (TNFi). PATIENTS AND METHODS The study population included all RA patients receiving adalimumab or etanercept a as first-line biologic drug, extracted from a local registry. Enrolled patients were stratified into 3 subgroups according to baseline concomitant MTX: no MTX, low-dose MTX (≤10 mg/wk), and high-dose MTX (≥12.5 mg/wk). The 2-year persistence of the initial MTX regimen was computed by the Kaplan-Meier method, and a Cox proportional hazard model was developed to examine potential predictors of MTX withdrawal/change of dosage. European League Against Rheumatism remission and good-to-moderate response were evaluated according to baseline MTX regimen and MTX maintenance over time. RESULTS A total of 330 patients (163 treated with adalimumab and 167 with etanercept) were included; 141 were prescribed TNFi without MTX and 112 received low-dose and 77 high-dose concomitant MTX. Male sex, younger age, and shorter mean disease duration were predictors of high-dose MTX use. Among MTX users (76.2% parenteral and 23.8% oral), initial MTX dose persisted over time in 79.9% at 1 year and 70.2% at 2 years. Fifty-one patients (27%) underwent MTX dose de-escalation/discontinuation because of intolerance/adverse events. The 2-year EULAR remission rate was higher in the patients receiving and maintaining high-dose MTX than in those receiving low-dose or no MTX (46.2% vs 29.5% and 23.4%, respectively; p=0.009). The same was true for good-to-moderate response rate (71.2% vs 52.6% and 50.4%, respectively; p=0.031). CONCLUSION In a real-life setting, about one-third of RA patients treated with TNFis experienced dose reduction/discontinuation of concomitant MTX because of intolerance/adverse events over a 2-year follow-up period. Initial high-dose MTX and its maintenance over time are associated with better 2-year clinical response.

Abstract
Side effects of methotrexate (MTX) especially hepatotoxicity limits clinical applications of this anticancer agent. Carboxypeptidase G2 (CPG2) is administrated for the treatment of elevated plasma concentrations of MTX. In this study, we have investigated the intracellular delivery of CPG2 fused to the transactivator transduction domain (TAT) and its protective effects against MTX-induced cell death of HepG2 cells. We have observed that both native and denatured forms of the enzyme transduced into the HepG2 cells efficiently in a concentration and time-dependent manner. The denatured protein transduced with higher efficiency than the native form and was functional inside the cells. MTX exposure significantly decreased HepG2 cell viability in a dose- and time-dependent manner. The cell viability after 24 and 48 h of incubation with 100 μM MTX was reduced to 44.37% and 17.69%, respectively. In cells pretreated with native and denatured TAT-CPG2 protein the cell viability was 98.63% and 86.31% after 24 and 48 h, respectively. Treatment with MTX increased the number of apoptotic HepG2 cells to 90.23% after 48 h. However, the apoptosis percentage in cells pretreated with native and denatured TAT-CPG2 was 21.49% and 22.28%, respectively. Our results showed that TAT-CPG2 significantly prevents MTX-induced oxidative stress by decreasing the formation of ROS and increasing the content of glutathione (GSH) and catalase activity. Our finding indicates that both native and denatured TAT-CPG2 strongly protect HepG2 cells against MTX-induced oxidative stress and apoptosis. Hence, intracellular delivery of CPG2 might provide a new therapeutic strategy for protecting against MTX mediated cytotoxicity.

Abstract
Rheumatoid arthritis (RA) is an autoimmune disease characterized by progressive cartilage and bone destruction. Activated macrophages that overexpress folic acid (FA) receptors play an important role in RA, due to their abundance in inflamed synovial membrane and joints. In an effort to deliver drugs to the inflamed tissues, multifunctional FA receptor-targeting and pH-responsive nanocarriers were developed. They were composed of lipids, polyethylene glycol (PEG)-poly(lactic-co-glycolic acid) (PLGA) forming a hydrophilic shell, FA around the hydrophilic shell as a targeting ligand, and poly(cyclohexane-1,4-diylacetone dimethylene ketal) (PCADK) and PLGA as a hydrophobic core. PCADK also acts as a pH-responsive material. Methotrexate (Mtx) was encapsulated in the nanoparticles, which exhibited pH-responsive release in vitro. Cellular uptake and cytotoxicity experiments revealed that FA-PEG-PLGA/PCADK-lipid nanoparticles loaded with Mtx (FA-PPLNPs) exhibited superior cellular uptake and higher cytotoxicity to activated macrophages than PPLNPs/Mtx. The therapeutic effect of FA-PPLNPs/Mtx in RA was confirmed in an adjuvant-induced arthritis rat model. These results suggest that the multifunctional folate receptor-targeting and pH-responsive nanocarriers are promising for the treatment of RA.

Abstract
BACKGROUND Methotrexate (MTX) treatment in rheumatoid arthritis (RA) has been associated with lower cardiovascular risk compared to other disease-modifying antirheumatic drugs (DMARDs). We sought to identify whether the MTX-associated cardioprotection involves changes in blood pressure (BP) and/or arterial function. METHODS Clinic and 24-hour peripheral and central systolic and diastolic BP (SBP and DBP), augmentation index (AIx), pulse wave velocity (PWV) and plasma asymmetric dimethylarginine (ADMA) were assessed in RA patients on stable treatment with either MTX ± other DMARDs (MTX group, n = 56, age 61 ± 13 years, 70% females) or other DMARDs (non-MTX group, n = 30, age 63 ± 12 years, 76% females). Measurements were performed at baseline and after 8 months. RESULTS After adjusting for visit, age, gender, body mass index, folic acid use and 28-joint disease activity score, the MTX group had significantly lower clinic peripheral SBP (-7.7 mmHg, 95% CI -13.2 to -2.3, p = 0.006) and DBP (-6.1 mmHg, 95% CI -9.8 to -2.4, p = 0.001) and clinic central SBP (-7.8 mmHg, 95% CI -13.1 to -2.6, p = 0.003) and DBP (-5.4 mmHg, 95% CI -9.1 to -1.6, p = 0.005) versus the non-MTX group. Furthermore, the MTX group had significantly lower 24-hour peripheral and central SBP and DBP and PWV versus the non-MTX group (p < 0.01 for all comparisons). By contrast, there were no significant between-group differences in AIx and ADMA. CONCLUSIONS RA patients on MTX treatment had significantly lower clinic and 24-hour peripheral and central BP compared to those who did not take MTX. The lower BP with MTX may be related to differences in PWV, but not in AIx or ADMA concentrations. Further longitudinal studies including randomized controlled trials are warranted to confirm these findings, to identify other possible mechanisms responsible for the effects of MTX on BP and PWV, and to establish whether these effects might account for the reduced cardiovascular risk with MTX.

Abstract
Although initially described as an anti-tumor mediator, tumor necrosis factor-alpha (TNF) is generally considered as the master pro-inflammatory cytokine. It plays a crucial role in the pathogenesis of inflammatory diseases, such as rheumatoid arthritis (RA), inflammatory bowel disease, ankylosing spondylitis (AS), and psoriasis. Consequently, anti-TNF therapy has become mainstay treatment for autoimmune diseases. Historically, anti-inflammatory agents were developed before the identification of TNF. Salicylates, the active components of Willow spp., were identified in the mid-19th century for the alleviation of pain, fever, and inflammatory responses. Study of this naturally occurring compound led to the discovery of aspirin, which was followed by the development of non-steroidal anti-inflammatory drugs (NSAIDs) due to the chemical advances in the 19th–20th centuries. Initially, the most of NSAIDs were organic acid, but the non-acidic compounds were also identified as NSAIDs. Although effective in the treatment of inflammatory diseases, NSAIDs have some undesirable and adverse effect, such as ulcers, kidney injury, and bleeding in the gastrointestinal tract. In the past two decades, anti-TNF biologics were developed. Drugs belong to this class include soluble TNF receptor 2 fusion protein and anti-TNF antibodies. The introduction of anti-TNF therapeutics has revolutionized the management of autoimmune diseases, such as RA, psoriatic arthritis (PsA), plaque psoriasis (PP), AS, CD and ulcerative colitis (UC). Nevertheless, up to 40% of patients have no response to anti-TNF treatment. Furthermore, this treatment is associated with some adverse effects such as increased risk of infection, and even triggered the de novo development of autoimmune diseases. Such harmful effect of anti-TNF treatment is likely caused by the global inhibition of TNF biological functions. Therefore, specific inhibition of TNF receptor (TNFR1 or TNFR2) may represent a safer and more effective treatment, as proposed by some recent studies. In this review article, the historical development of anti-inflammatory drugs after World War II as briefly described above will be reviewed and analyzed. The future trend in the development of novel TNF receptor-targeting therapeutics will be discussed in the context of latest progress in the research of TNF biology.

Abstract
Medical errors associated with low-dose methotrexate may be life-threatening. Prescribers should be cognizant of the medication's toxicities and the persistent challenges in preventing adverse events. This article reviews the properties of methotrexate and its common drug-drug interactions. Best practices from the Institute for Safe Medication Practices, aimed at reducing methotrexate errors, are highlighted.
