Abstract
OBJECTIVE To assess the risk of major adverse cardiovascular events (MACE) in patients with rheumatoid arthritis (RA) treated with tocilizumab compared to those treated with the tumor necrosis factor inhibitor etanercept. METHODS This randomized, open-label, parallel-group trial enrolled patients with active seropositive RA (n = 3,080) who had an inadequate response to conventional synthetic disease-modifying antirheumatic drugs and who had at least 1 cardiovascular (CV) risk factor. Patients were randomly assigned 1:1 to receive open-label tocilizumab at 8 mg/kg/month or etanercept at 50 mg/week. All patients were followed up for a mean of 3.2 years. The primary end point was comparison of time to first occurrence of MACE. The trial was powered to exclude a relative hazard ratio for MACE of 1.8 or higher in the tocilizumab group compared to the etanercept group. RESULTS By week 4 of treatment, the serum low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglyceride levels were a median 11.1%, 5.7%, and 13.6% higher, respectively, in patients receiving tocilizumab compared to those receiving etanercept (each P < 0.001). During follow-up, 83 MACE occurred in the tocilizumab group compared to 78 MACE in the etanercept group. The estimated hazard ratio for occurrence of MACE in the tocilizumab group relative to the etanercept group was 1.05 (95% confidence interval 0.77-1.43). Results were similar in sensitivity analyses and in the on-treatment population analysis. Adverse events occurred more frequently in the tocilizumab group, including serious infection and gastrointestinal perforation. CONCLUSION The results of this trial, which provide insights into the CV safety of tocilizumab as compared to etanercept, ruled out a risk for occurrence of MACE of 1.43 or higher in patients treated with tocilizumab. This result should be interpreted in the context of the clinical efficacy and non-CV safety of tocilizumab.

Journal of clinical pharmacy and therapeutics. 2020;(4):674-681
Abstract
WHAT IS KNOWN AND OBJECTIVE Several clinical trials have attempted to evaluate the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy in patients with active rheumatoid arthritis (RA), but their relative efficacy and safety as monotherapy remain unclear due to the lack of data from head-to-head comparison trials. The relative efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy for rheumatoid arthritis (RA) were assessed. METHODS We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) and examine the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy relative to placebo in patients with RA. RESULTS AND DISCUSSION Five RCTs comprising 1547 patients met the inclusion criteria. Compared with placebo, tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib as monotherapy showed a significantly higher American College of Rheumatology 20% (ACR20) response rate. Peficitinib 150 mg monotherapy showed the highest ACR20 response rate (odds ratio, 17.24.39; 95% credible interval, 6.57-51.80). The ranking probability based on the surface under the cumulative ranking curve indicated that peficitinib 150 mg had the highest probability of being the best treatment for achieving the ACR20 response rate, followed by peficitinib 100 mg, filgotinib 200 mg, filgotinib 100 mg, tofacitinib 5 mg, upadacitinib 15 mg, baricitinib 4 mg and placebo. However, the number of patients who experienced serious adverse events did not differ significantly between the JAK inhibitors, except for tofacitinib 5 mg, and placebo. WHAT IS NEW AND CONCLUSION All five JAK inhibitors-tofacitinib, baricitinib, upadacitinib, filgotinib and peficitinib-were efficacious monotherapy interventions for active RA, and differences were noted in their efficacy and safety in monotherapy.

How does methotrexate work?
Alqarni, AM, Zeidler, MP
Biochemical Society transactions. 2020;(2):559-567
Abstract
Developed over 70 years ago as an anti-folate chemotherapy agent, methotrexate (MTX) is a WHO 'essential medicine' that is now widely employed as a first-line treatment in auto-immune, inflammatory diseases such as rheumatoid arthritis (RA), psoriasis and Crone's disease. When used for these diseases patients typically take a once weekly low-dose of MTX - a therapy which provides effective inflammatory control to tens of millions of people worldwide. While undoubtedly effective, our understanding of the anti-inflammatory mechanism-of-action of low-dose MTX is incomplete. In particular, the long-held dogma that this disease-modifying anti-rheumatic drug (DMARD) acts via the folate pathway does not appear to hold up to scrutiny. Recently, MTX has been identified as an inhibitor of JAK/STAT pathway activity, a suggestion supported by many independent threads of evidence. Intriguingly, the JAK/STAT pathway is central to both the inflammatory and immune systems and is a pathway already targeted by other RA treatments. We suggest that the DMARD activity of MTX is likely to be largely mediated by its inhibition of JAK/STAT pathway signalling while many of its side effects are likely associated with the folate pathway. This insight into the mechanism-of-action of MTX opens the possibility for repurposing this low cost, safe and effective drug for the treatment of other JAK/STAT pathway-associated diseases.

Abstract
Repurposing of antirheumatic drugs has garnered global attention. The aim of this article is to overview available evidence on the use of widely used antirheumatic drugs hydroxychloroquine, methotrexate and colchicine for additional indications. Hydroxychloroquine has endothelial stabilizing and anti-thrombotic effects. Its use has been explored as an adjunctive therapy in refractory thrombosis in antiphospholipid syndrome. It may also prevent recurrent pregnancy losses in the absence of antiphospholipid antibodies. Hydroxychloroquine favourably modulates atherogenic lipid and glycaemic profiles. Methotrexate has been tried for modulation of cardiovascular events in non-rheumatic clinical conditions, although a large clinical trial failed to demonstrate a benefit. Colchicine has been shown to successfully reduce the risk of recurrent cardiovascular events in a large multicentric trial. Potential antifibrotic effects of colchicine require further exploration. Hydroxychloroquine, methotrexate and colchicine are also being tried at different stages of the ongoing Coronavirus Disease 19 (COVID-19) pandemic for prophylaxis and treatment. While the use of these agents is being diversified, their adverse effects should be timely diagnosed and prevented. Hydroxychloroquine can cause retinopathy and rarely cardiac and auditory toxicity, retinopathy being dose and time dependent. Methotrexate can cause transaminitis, cytopenias and renal failure, particularly in acute overdoses. Colchicine can rarely cause myopathies, cardiomyopathy, cytopenias and transaminitis. Strong evidence is warranted to keep balance between benefits of repurposing these old antirheumatic drugs and risk of their adverse effects.

Atherosclerotic cardiovascular disease prevention in rheumatoid arthritis.
Semb, AG, Ikdahl, E, Wibetoe, G, Crowson, C, Rollefstad, S
Nature reviews. Rheumatology. 2020;(7):361-379
Abstract
Patients with rheumatoid arthritis (RA) are at high risk of developing cardiovascular disease (CVD). Inflammation has a pivotal role in the pathogenesis of CVD. RA is an inflammatory joint disease and, compared with the general population, patients with RA have approximately double the risk of atherosclerotic CVD, stroke, heart failure and atrial fibrillation. Although this high risk of CVD has been known for decades, patients with RA receive poorer primary and secondary CVD preventive care than other high-risk patients, and an unmet need exists for improved CVD preventive measures for patients with RA. This Review summarizes the evidence for atherosclerotic CVD in patients with RA and provides a contemporary analysis of what is known and what needs to be further clarified about recommendations for CVD prevention in patients with RA compared with the general population. The management of traditional CVD risk factors, including blood pressure, lipids, diabetes mellitus and lifestyle-related risk factors, as well as the effects of inflammation and the use of antirheumatic medication on CVD risk and risk management in patients with RA are discussed. The main aim is to provide a roadmap of atherosclerotic CVD risk management and prevention for patients with RA.

Expert Perspectives On Clinical Challenges: Expert Perspectives: Challenges in Scleroderma.
Simms, RW
Arthritis & rheumatology (Hoboken, N.J.). 2020;(9):1415-1426
Abstract
You are consulted to evaluate a 56-year-old woman with known Raynaud's phenomenon, finger swelling of several; months' duration, and new hypertension with a blood pressure of 160/100 mm/Hg. She also reports progressive shortness of breath. Physical examination reveals telangiectasias, sclerodactyly, and proximal skin sclerosis (thick shiny skin on the chest and upper arms), and bibasilar crackles are found on chest examination. Laboratory tests reveal evidence of microangiopathic hemolytic anemia, thrombocytopenia, and elevation of the serum creatinine level (previously normal), and chest computed tomography shows evidence of ground-glass opacification in both lower lung fields.

Abstract
Severe acute respiratory syndrome coranovirus-2 (SARS-CoV-2) infection has become an important health-care issue worldwide. The coronavirus disease 2019 (COVID-19) has also raised concerns among patients with inflammatory rheumatic conditions and their treating physicians. There are emerging data regarding the potential risks of SARS-CoV-2 for this particular patient group. However, less is known with regard to the course of COVID-19 among patients receiving IL-17 inhibitors. The aim of the current article is to review the growing body of knowledge on the course/management of COVID-19 in patients with inflammatory rheumatic diseases by presenting a SARS-CoV-2 infected case with ankylosing spondylitis under secukinumab therapy. A 61-year old patient with ankylosing spondylitis who was on secukinumab therapy for 5 months admitted with newly onset fever and gastrointestinal complaints. After being hospitalized, she developed respiratory manifestations with focal pulmonary ground-glass opacities and multiple nodular densities in both lungs. The patient was tested positive for SARS-CoV-2 infection. Substantial clinical improvement was obtained following a management plan, which included tocilizumab, hydroxychloroquine, prednisolone and enoxaparin sodium. PubMed/MEDLINE and Scopus databases were searched by using relevant keywords and their combinations. The literature search revealed four articles reporting the clinical course of COVID-19 in seven rheumatic patients on secukinumab. The clinical course of SARS-CoV-2 infection was mild in most of these patients, while one of them experienced severe COVID-19. Interleukin-17 has been related to the hyperinflammatory state in COVID-19 and IL-17 inhibitors were presented as promising targets for the prevention of aberrant inflammation and acute respiratory distress in COVID-19. However, this hypothesis still remains to be proved. Further studies are warranted in order to test the benefits and risks of IL-inhibitors in SARS-CoV-2 infected individuals.

Lupus. 2020;(3):303-310
Abstract
Juvenile-onset systemic lupus erythematosus (JSLE) presents with an aggressive course and high morbidity associated with disease and treatment. JSLE patients have a poorer health-related quality of life (HRQoL) when compared with age-matched patients with other rheumatologic disorders. We aim to summarize the impact of current pharmacological therapies on the HRQoL of JSLE patients. Search strategies were developed across seven databases. Randomized clinical trials (RCTs) and cohort studies comparing interventions to standard therapy, placebo or pre-post cohort comparisons for more than 4 weeks were included. The outcome included self-reported scales compared at baseline and a therapeutic time point. Risk of bias was evaluated by using the Cochrane risk of bias tool and the Newcastle-Ottawa quality assessment scale. A total of 2812 articles were narrowed down to 309 for full-text screening. Four RCTs and one prospective cohort study, with a total of 634 JSLE patients, met the inclusion criteria. Four of the studies had a controlled intervention plus standard therapy compared with standard therapy alone or placebo. Multiple indices were used to evaluate HRQoL. These included the Pediatric Quality of Life Inventory, Childhood Health Assessment Questionnaire, Simple Measure of Impact of Lupus Erythematosus in Youngsters tool, Kids Fatigue Severity Scale and Child Depression Inventory. A single study reported a significant improvement while remaining studies reported no difference or failed to report the statistical analysis. Although HRQoL is significantly impaired in JSLE, evidence regarding its improvement is limited due to the small number of eligible studies, heterogeneity in scales, and HRQoL domains. A universal HRQoL questionnaire for JSLE needs to be established and used in both the research and clinical setting. All studies should adhere to reporting guidelines.

Abstract
OBJECTIVE To conduct a systematic literature review and meta-analysis to estimate the incidence of anaemia, leucopoenia, neutropenia and thrombocytopenia associated with MTX plus folic acid among patients with rheumatic diseases. METHODS We searched MEDLINE, PubMed and EMBASE through August 2016 for all randomized controlled clinical trials with a MTX monotherapy arm. We excluded randomized controlled clinical trials for cancer and included only double-blind studies that reported on haematologic adverse events. Studies were excluded if patients did not receive folic acid or leucovorin supplementation. Full text articles were assessed by two independent reviewers. Incidence estimates were calculated using random-effects models. RESULTS Of 1601 studies identified, 30 (1.87%) were included, representing 3858 patients; all had RA. Seventeen trials reported on anaemia (n = 2032), 17 reported on leucopoenia (n = 2220), 16 reported on neutropenia (n = 2202) and 12 reported on thrombocytopenia (n = 1507). The incidence for any anaemia was 2.55% (95% CI 0.60-5.47%), any leucopoenia 1.17% (95% CI 0.16-2.80%), any neutropenia 1.77% (95% CI 0.33-4.00%), and any thrombocytopenia 0.19% (95% CI 0.00-0.86%). Four cases of severe anaemia were reported, as defined by authors, along with three cases of severe neutropenia. No cases of severe leucopoenia, severe thrombocytopenia or pancytopenia were reported. CONCLUSION Cytopenias are an uncommon side effect of low-dose MTX with folic acid supplementation among RA patients. Further research is needed to reach a more precise estimate.
