Nature reviews. Rheumatology. 2019;(7):391-402
Abstract
The management of inflammatory rheumatic diseases during pregnancy and breastfeeding has undergone considerable change in the past few years. Modern therapeutics, including biologic and targeted synthetic DMARDs, have enabled substantial improvements in the control of rheumatic diseases, resulting in more patients with severe disease considering pregnancy. Therefore, management of disease for these patients needs to be discussed with clinicians before, during and after pregnancy and patients need to know what complications they might experience before they become pregnant. This Review summarizes the effects pregnancy has on various rheumatic diseases and the effects these diseases have on pregnancy, as well as providing advice regarding the alteration and monitoring of therapy before, during and after pregnancy.

Arthritis & rheumatology (Hoboken, N.J.). 2019;(11):1788-1800
Abstract
OBJECTIVE To evaluate the efficacy, including capacity for inhibition of radiographic progression, and safety of upadacitinib, a JAK1-selective inhibitor, as compared to placebo or adalimumab in patients with rheumatoid arthritis (RA) who have experienced an inadequate response to methotrexate (MTX). METHODS In total, 1,629 RA patients with an inadequate response to MTX were randomized (2:2:1) to receive upadacitinib (15 mg once daily), placebo, or adalimumab (40 mg every other week) while continuing to take a stable background dose of MTX. The primary end points were achievement of an American College of Rheumatology 20% (ACR20) improvement response and a Disease Activity Score in 28 joints using C-reactive protein level (DAS28-CRP) of <2.6 in the upadacitinib group compared to the placebo group at week 12; inhibition of radiographic progression was evaluated at week 26. The study was also designed and powered to test for the noninferiority and superiority of upadacitinib compared to adalimumab, as measured both clinically and functionally. RESULTS At week 12, both primary end points were met in patients receiving upadacitinib compared to those receiving placebo (P ≤ 0.001). An ACR20 improvement response was achieved by 71% of patients in the upadacitinib group compared to 36% in the placebo group, and a DAS28-CRP score of <2.6 was observed in 29% of patients receiving upadacitinib compared to 6% of patients receiving placebo. Upadacitinib was superior to adalimumab based on the ACR50 response rate, achievement of a DAS28-CRP score of ≤3.2, change in pain severity score, and change in the Health Assessment Questionnaire disability index. At week 26, more patients receiving upadacitinib than those receiving placebo or adalimumab achieved low disease activity or remission (P ≤ 0.001). Radiographic progression was significantly inhibited in patients receiving upadacitinib and was observed in fewer upadacitinib-treated patients than placebo-treated patients (P ≤ 0.001). Up to week 26, adverse events (AEs), including serious infections, were comparable between the upadacitinib and adalimumab groups. The proportions of patients with serious AEs and AEs leading to discontinuation were highest in the adalimumab group; the proportions of patients with herpes zoster and those with creatine phosphokinase (CPK) elevations were highest in the upadacitinib group. Three malignancies, 5 major adverse cardiovascular events, and 4 deaths were reported among the groups, but none occurred in patients receiving upadacitinib. Six venous thromboembolic events were reported (1 in the placebo group, 2 in the upadacitinib group, and 3 in the adalimumab group). CONCLUSION Upadacitinib was superior to placebo and adalimumab for improving signs, symptoms, and physical function in RA patients who were receiving background MTX. In addition, radiographic progression was significantly inhibited by upadacitinib as compared to placebo. The overall safety profile of upadacitinib was generally similar to that of adalimumab, except for higher rates of herpes zoster and CPK elevations in patients receiving upadacitinib.

Abstract
OBJECTIVE To investigate the effectiveness a cream onjoint pain and swelling in patients with rheumatoid arthritis (RA). The cream, topically used, in was prepared with Tripterygium wilfordii Hook F (TwHF), Mangxiao (Nalrii Sulfas), Chuanxiong (Rhizoma Chuanxiong), stir-frying with liquid adjuvant Ruxiang (Olibanum), and stir-frying with liquid adjuvant Moyao (Myrrh). METHODS Patients were 1∶1 randomized to add-on TwHF cream twice a day or placebo for 4 weeks. The primary endpoint was achievement rate of 20% improvement in American College of Rheumatology criteria (ACR20) at week 4. Secondary endpoints were ACR50, 28-joint count Disease Activity Score (DAS28) improvement and safety profiles. Statistical analyses were performed using intention to treat analysis (ITT) set. RESULTS A total of 70 active RA patients were enrolled. At week 4, the ACR20 was 34.3% (12/35) in TwHF cream group and 11.4% (4/35) in placebo group (P = 0.015). Similarly, a higher ACR50 responder proportion was seen in TwHF cream group with 17.1% (6/35) comparing to it in placebo group with 2.9% (1/35) (P = 0.046). The TwHF cream group also had more improvement than the placebo group on DAS28-ESR (1.1 vs 0.5, P = 0.001), DAS28- CRP (1.4 vs 0.7, P = 0.001), tender joint count (5.5 vs 2.6, P = 0.018), swollen joint count (3.5 vs 1.6, P = 0.003) and Physician's global assessment (25.8 vs 13.0, P = 0.002), as well as C-reactive protein (11.2 vs 2.7, P = 0.048). Except 2 skin allergy events in TwHF cream group, no other substantive adverse events were observed. CONCLUSION On the short term, TwHF cream is likely to be an effective and safety complimentary treatment in patients with active RA.

Castagné, B, Viprey, M, Martin, J, Schott, AM, Cucherat, M, Soubrier, M
PloS one. 2019;(8):e0220178
Abstract
OBJECTIVES Our objective was to compare the cardiovascular safety of tocilizumab and other biological disease-modifying antirheumatic drugs (bDMARD) in rheumatoid arthritis using a network meta-analysis (NMA). METHODS A systematic literature search through May 2018 identified randomized controlled trials (RCT) or observational studies (cohort only) reporting cardiovascular outcomes of tocilizumab (TCZ) and/or abatacept (ABA) and/or rituximab (RTX) and/or tumor necrosis factor inhibitors (TNFi) in rheumatoid arthritis patients. The composite primary outcome was the rate of major adverse cardiovascular outcomes (MACE, myocardial infarction (MI), peripheral artery disease (PAD) and cardiac heart failure (CHF)). RESULTS 19 studies were included in the NMA, including 11 RCTs and 8 cohort studies. We found less events with RTX (5.41 [1.70;17.26]. We found no difference between TCZ and other treatments. Concerning MI, we found no difference between TCZ and csDMARD (4.23 [0.22;80.64]), no difference between TCZ and TNFi (2.00 [0.18;21.84]). There was no difference between TCZ and csDMARD (1.51[0.02;103.50] and between TCZ and TNFi (1.00 [0.06;15.85]) for stroke event. With cohorts and RCT NMA, we found no difference between TCZ and other treatments for MACE (0.66 [0.42;1.03] with ABA, 1.04 [0.60;1.81] with RTX, 0.78[0.53;1.16] and 0.91 [0.54;1.51] with csDMARD), but the risk of myocardial infarction was lower with TCZ compared to ABA (0.67 [0.47;0.97]). We lacked data to compare TCZ and other bDMARD for stoke and MI. Not enough data was available to perform a NMA for CHF and PAD. CONCLUSIONS Despite an increase in cholesterol levels, TCZ has safe cardiovascular outcomes compared to other bDMARD.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic systemic autoimmune inflammatory disorder that increases the risk of developing cardiovascular disease. There is accumulating evidence that the RA disease state accelerates the formation of atherosclerotic plaques. Treatments for RA improve joint symptomatology and may reduce inflammation, but consideration of their effects on the cardiovascular system is generally low priority. OBJECTIVE Since cardiovascular disease is the leading cause of mortality in RA patients, the impact of RA therapies on atherosclerosis is an area in need of attention and the focus of this review. RESULTS The drugs used to treat RA may be analgesics, conventional disease-modifying anti-rheumatic drugs, and/or biologics, including antibodies against the cytokine tumor necrosis factor-α. Pain relievers such as nonselective non-steroidal anti-inflammatory drugs and cyclooxygenase inhibitors may adversely affect lipid metabolism and cyclooxygenase inhibitors have been associated with increased adverse cardiovascular events, such as myocardial infarction and stroke. Methotrexate, the anchor disease-modifying anti-rheumatic drug in RA treatment has multiple atheroprotective advantages and is often combined with other therapies. Biologic inhibitors of tumor necrosis factor-α may be beneficial in preventing cardiovascular disease because tumor necrosis factor-α promotes the initiation and progression of atherosclerosis. However, some studies show a worsening of the lipid profile in RA with blockade of this cytokine, leading to higher total cholesterol and triglycerides. CONCLUSION Greater understanding of the pharmacologic activity of RA treatments on the atherosclerotic process may lead to improved care, addressing both damages to the joints and heart.

Methotrexate preferentially affects Tc1 and Tc17 subset of CD8 T lymphocytes.
Sandhu, A, Ahmad, S, Kaur, P, Bhatnagar, A, Dhawan, V, Dhir, V
Clinical rheumatology. 2019;(1):37-44
Abstract
Rheumatoid arthritis is considered a T-lymphocyte-mediated disease. However, studies have focussed on CD4 T-lymphocytes, ignoring CD8 T-lymphocytes despite the latter being found abundantly in the synovium. Specifically, there is little data of the effect of methotrexate, the gold-standard DMARD, on various CD8 cytokine T-lymphocyte subsets and conflicting data on CD4 subsets. In this prospective study, patients with active rheumatoid arthritis, who were 18 to 65 years of age, were treated with methotrexate (up to 25 mg per week) for 24 weeks. At baseline and 24 weeks, frequencies of CD8+IFNγ+, CD8+IL17+, CD8+IL4+, corresponding CD4 subsets and plasma levels of IFNγ, IL-12, IL-10, IL-4 and IL-17 were determined by flow cytometry. These are summarised as median (IQR = interquartile range, 25th-75th percentile) and paired data compared using Wilcoxon signed rank test. This study included 67 patients (F/M = 4:1) with rheumatoid arthritis, 57 (85%) being RF positive and 20 receiving prednisolone at baseline. Mean (± SD) dose of methotrexate at 24 weeks was 22.9 ± 3.0 mg per week. On treatment with methotrexate, there was a significant (p = 0.04) decline in CD8+IFNγ+ cells from 37.2 (IQR 19.4-60.2) to 22.7% (IQR 8.5-49.7) and a marginal increase in CD8+IL17+ cells from 0.3 (IQR 0.1-0.6) to 0.4 (IQR 0.2-1.2), p = 0.006. There was no significant change in the other subsets. There was also a significant decline in circulating levels of IL-12, IL-10 and IL-17 and marginal increase in IL-4. On evaluating by response, non-responders but not responders had a significant increase in CD8+IL17+ (p = 0.01). There is a significant decline of CD8+IFNγ+ T cells and marginal increase in CD8+IL17+ T cells after methotrexate. Change in Tc1 subset may be mediated through reduction in IL-12 levels.

Methotrexate mechanism in treatment of rheumatoid arthritis.
Friedman, B, Cronstein, B
Joint bone spine. 2019;(3):301-307
Abstract
Methotrexate has been used in treatment of rheumatoid arthritis (RA) since the 1980s and to this day is often the first line medication for RA treatment. In this review, we examine multiple hypotheses to explain the mechanism of methotrexate efficacy in RA. These include folate antagonism, adenosine signaling, generation of reactive oxygen species (ROS), decrease in adhesion molecules, alteration of cytokine profiles, and polyamine inhibition amongst some others. Currently, adenosine signaling is probably the most widely accepted explanation for the methotrexate mechanism in RA given that methotrexate increases adenosine levels and on engagement of adenosine with its extracellular receptors an intracellular cascade is activated promoting an overall anti-inflammatory state. In addition to these hypotheses, we examine the mechanism of methotrexate in RA from the perspective of its adverse effects and consider some of the newer genetic markers of methotrexate efficacy and toxicity in RA. Lastly, we briefly discuss the mechanism of additive methotrexate in the setting of TNF-α inhibitor treatment of RA. Ultimately, finding a clear explanation for the pathway and mechanism leading to methotrexate efficacy in RA, there may be a way to formulate more potent therapies with fewer side effects.

Abstract
Social determinants of health play a crucial role in health and disease. In current times, it has become increasingly known that biological and non-biological factors are potentially linked and help to drive disease. For example, links between various comorbidities, both physical and mental illnesses, are known to be driven by social, environmental and economic determinants. This contributes to worse disease outcomes. This article discusses the concept of syndemics, which although well-described in some conditions, represents a novel concept in the context of rheumatic and musculoskeletal diseases. Written in the form of a viewpoint, the article focuses on a novel theoretical framework for studying inflammatory arthritis, based on a syndemic approach that takes into account the social context, biocultural disease interaction, and socio-economic characteristics of the setting. Syndemics involving inflammatory arthritis may be most likely in a social context involving limited access to health care, lack of physical activity and obesogenic diets, high rates of alcohol consumption, and high exposure to stressful life events.

Verberne, EA, de Haan, E, van Tintelen, JP, Lindhout, D, van Haelst, MM
Reproductive toxicology (Elmsford, N.Y.). 2019;:125-139
Abstract
Methotrexate is a folic acid antagonist known to be teratogenic in humans. Several cases of congenital malformations after fetal exposure to methotrexate have been published, resulting in the establishment of the 'fetal methotrexate syndrome'. However, it is unclear which congenital anomalies can truly be attributed to methotrexate exposure. The objective of this review is to delineate a consistent phenotype of the fetal methotrexate syndrome. We performed a systematic review that yielded 29 cases of (congenital) anomalies after in utero exposure to methotrexate and compared their malformation pattern to that of children and fetuses with congenital anomalies in general. Statistically significant higher proportions of microcephaly, craniosynostosis, tetralogy of Fallot, pulmonary valve atresia, limb reduction defects and syndactyly were found in the methotrexate group, indicating that these congenital anomalies are truly part of the fetal methotrexate syndrome. These results aid clinicians with diagnosing fetal methotrexate syndrome.

Abstract
BACKGROUND Rheumatoid arthritis (RA) is a chronic immune-mediated inflammatory disease which can cause significant disability, morbidity, mortality, and impaired fertility. It commonly affects women of childbearing age. Managing rheumatoid arthritis (RA) in the perinatal period poses challenges. There is concern about the teratogenic effects of many traditional disease-modifying anti-rheumatic drugs (DMARDs) and an ever-growing list of new therapeutic options with limited data in pregnancy and breastfeeding. AIMS We aimed to create a standardized approach to pharmacological management of RA patients seen in our newly established Rheumatology and Reproductive Health Service. METHODS We reviewed relevant publications on the use of anti-rheumatic drugs in pregnancy. These include recent guidelines from The British Society for Rheumatology (BSR) and British Health Professionals in Rheumatology (BHPR) and the European League Against Rheumatism (EULAR). RESULTS After considering relevant publications, we developed a Saint Vincent's University Hospital/National Maternity Hospital consensus protocol for evidence-based medication in pregnancy in RA. CONCLUSIONS RA tends to improve during pregnancy and flare postpartum. Several anti-rheumatic medication options during pregnancy and breastfeeding are now available including anti-tumor necrosis factor (anti-TNF) agents. Good disease control at all stages of reproduction is important to ensure best outcome for both mother and baby.
