Cardiovascular events in early RA are a result of inflammatory burden and traditional risk factors: a five year prospective study

Beneficial effects of hydroxychloroquine on blood lipids and glycated haemoglobin: A randomised interventional study in patients with rheumatoid arthritis and systemic lupus erythematosus

INTRODUCTION

Hydroxychloroquine (HCQ) exerts a large reduction of cardiovascular risk in patients with inflammatory diseases, but the mechanisms are not fully known. The aim of this study was to study potential mechanisms for this.

METHODS

This interventional study (EudraCT 2014-005418-45) in 30 patients (23 with rheumatoid arthritis, 7 with systemic lupus erythematosus) investigates the effects of HCQ on cardiovascular risk factors and arterial stiffness in patients with inflammatory disease. Blood lipids, blood pressure, blood glucose, glycated haemoglobin (HbA1c) and arterial stiffness was assessed at initiation, after four weeks of treatment and after eight weeks of treatment with 200 mg HCQ daily.

RESULTS

After four weeks of treatment with HCQ, total cholesterol had decreased from 5.4 mmol/L to 5.1 mmol/L (p<0.001), low-density lipoproteins from 3,0 mmol/L to 2.7 mmol/L (p<0.001) and apolipoprotein B from 0.96 g/L to 0.90 g/L (p<0.01). Those levels remained unchanged after eight weeks of treatment with HCQ. Levels of triglycerides, high-density lipoproteins and apolipoprotein A1 remained unchanged during the study. HbA1c decreased in most patients, especially in patients with high levels at start of HCQ, but increased HbA1c was seen in patients with low levels at start of treatment with HCQ. No significant effect was seen on blood pressure or any measure of arterial stiffness.

CONCLUSION

This study does not identify the mechanisms of cardiovascular risk reduction from HCQ. Arterial stiffness is not affected by HCQ. The impact of HCQ on HbA1c and blood lipids is rapid, but of modest magnitude, and these effects do not fully explain the reduced risk of cardiovascular disease seen in observational studies. The mechanisms of cardiovascular risk reduction from HCQ are yet not completely known.

Prevalence of Cardiovascular and Cancer Risk Factors Among Rheumatoid Arthritis Patients Prescribed JAK Inhibitors and Tumor Necrosis Factor Inhibitors: A Cross-Sectional Study

OBJECTIVE

The study was to determine the prevalence of baseline risk factors for cardiovascular outcomes and cancer among commercially-insured patients with rheumatoid arthritis (RA) during their first dispensed treatment for either tumor necrosis factor inhibitors (TNFi) or JAK inhibitors (JAKi).

METHODS

Patients with RA from August 16, 2019 to March 31, 2022 were identified in the Merative MarketScan Commercial and Medicare databases. The first date that a TNFi or JAKi was dispensed was the index date, and baseline risk factors were assessed among patients continuously eligible for 12 months before the index date. Patients who had the following were stratified into an elevated risk category: age ≥65 years, smoking, or a history of a major adverse cardiovascular event, venous thromboembolism, or cancer. The prevalence of modifiable risk factors was also reported: hypertension, hyperlipidemia, obesity, and diabetes. The crude prevalence and prevalence difference (PD) were reported.

RESULTS

A total of 12,673 patients (TNFi [n = 7,748; 61%] and JAKi [n = 4,925; 39%]) met inclusion criteria. The prevalence of elevated risk was the same for all patients using TNFi (n = 2,051; 26%) and JAKi (n = 1,262; 26%). Compared with patients having low risk, patients with an elevated risk also had a higher prevalence of at least one primary modifiable risk factor for both patients using JAKi (79% vs 58%; PD 21%, 95% confidence interval [CI] 18%-24%) and TNFi (81% vs 60%; PD 21%, 95% CI 19%-23%).

CONCLUSION

In recent years, JAKi and TNFi were used in similar proportions to treat RA among commercially-insured patients at elevated cardiovascular and cancer risk. Because uncontrolled disease, modifiable comorbidities, and treatment with JAKi are associated with these adverse events, future studies evaluating how practice patterns may be affected by the emergence of safety data will be of value.

Association of serum concentrations of remnant cholesterol with incident cardiovascular disease in patients with rheumatoid arthritis: A real-world data from 2001 to 2022

BACKGROUND

Remnant cholesterol (RC) promotes cardiovascular disease (CVD) in the general population, but its role among rheumatoid arthritis (RA) patients remains unknown. We aimed to investigate circulating RC levels associated with incident CVD among Chinese patients with RA.

METHODS

A total of 1018 RA patients free of baseline CVD were included and followed up in a prospective RA CVD cohort from 2001 to 2022. Fasting serum levels of triglycerides, total cholesterol (TC), low-density (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured, while RC and Non-HDL-C levels were calculated. The primary exposure was RC levels. A LASSO Cox model was used to select covariates. The Fine-Gray competing risk model was used to estimate hazard ratios (HRs).

RESULTS

RA patients had a mean age of 53.9 years, and 802 (78.8%) were females. After a median follow-up of 5.54 years, 131 patients developed CVD with an incidence rate of 21.6 per 1000 person-years. Continuous and quartile-categorized RC levels were associated with incident CVD before and after multivariate adjustment and Bonferroni correction (all P < 0.001). There were no robust associations of other lipids with incident CVD. The fully adjusted HRs for RC were 2.30 (95% CI 1.58-3.35) per 1 mmol/L increase, and 2.40 (1.36-4.25) and 2.81 (1.60-4.94) for patients in the 3rd and 4th versus the 1st quartile, respectively.

CONCLUSIONS

Circulating RC levels are positively associated with incident CVD among Chinese RA patients independent of known risk factors, implying its clinically preferable use for improving the stratification of CVD risk in RA patients.

Factors associated with incident cardiovascular disease in patients with rheumatoid arthritis: A scoping review

INTRODUCTION

Rheumatoid arthritis (RA) is the most common form of autoimmune inflammatory arthritis and is associated with various comorbidities including cardiovascular disease (CVD). This scoping review summarizes the current evidence on longitudinal cohort studies assessing potential factors associated with the incidence of cardiovascular events among patients with RA.

METHODS

Scopus, PubMed, Ovid MEDLINE and Cochrane databases were used to identify longitudinal cohort studies investigating the incidence of CVD among RA patients. Using predetermined inclusion and exclusion criteria, two reviewers screened and extracted the relevant studies independently to map the existing literature on this topic. The extracted data included study characteristics, demographics, comorbidities, behavioural and RA-related factors.

RESULTS

Thirty-three research papers were included with a mean follow-up duration of 7.8 years. The sample size of the studies ranged from 182 to 4,311,022 subjects, the mean age from 46.1 to 72.3 years, and on average, 34.6% of the participants were male. The following factors were reported to be associated with a higher incidence of CVD in RA patients: older age, male sex, co-morbid hypertension, diabetes, and/or dyslipidemia, the presence of rheumatoid factor (RF) and/or acute phase reactants. Among RA treatments, glucocorticoids were shown to increase CVD incidence while DMARDs, especially methotrexate, were associated with a lower incidence of CVD.

CONCLUSION

This review offers a comprehensive summary of the current literature reporting on risk factors for CVD incidence among RA patients. Future research should focus on the less studied factors, including socioeconomic status, physical inactivity, alcohol consumption, sleep habits and dietary patterns as well as some RA-related factors such as anti-citrullinated protein antibodies and functional impairment.

Participation in cardiovascular screening consultations, the who, when and why - A cohort study on patients with rheumatoid arthritis

BACKGROUND

In accordance with the EULAR recommendations, the Danish Hospital for Rheumatic Diseases have systematically invited patients with rheumatoid arthritis (RA) to cardiovascular (CV) risk assessment since 2011. Patients with high risk are invited to a follow-up screening after one year. To optimize the screening and tailor it to individual needs, information about who accepts vs. declines follow-up is needed. Thus, the aim of this study was to explore participation in systematic CV risk assessment among patients with RA. Furthermore, to explore differences between patients with low vs. high risk, and between patients with high risk who accept vs. decline follow-up.

METHODS

Data from 2,222 outpatients with RA in the period 2011-2021 were retrieved, and of these 1,522 were under 75 years and eligible to be invited. To assess the 10-year risk for CV death, the modified Systematic Coronary Risk Evaluation (mSCORE), derived by multiplying the SCORE by 1.5, was used. Logistic regression analyses were used to explore differences in CV risk factors (triglycerides, HbA1c, lifestyle factors) and measures of disease impact (pain, fatigue, patient global assessment, HAQ, EQ-5D-5L) between patients with low vs. high risk. Differences between high risk patients who accepted vs. declined follow-up were analysed using Wilcoxon rank sum test and chi-squared test for groups.

RESULTS

One thousand one hundred forty-nine received a CV screening invitation and 91 declined participation. Patients with high risk had significantly longer disease duration (OR; 95 CI) (1.017; 1.002-1.032), higher levels of triglycerides (1.834; 1.475-2.280), HbA1C (1.046; 1.020-1.070), pain (1.006; 1.001-1.012), and HAQ-score (1.305; 1.057-1.612) compared to patients with low risk and they more often declined follow-up (43% vs. 28%, p < 0.001). Those who declined a follow-up invitation were older (p = 0.016) and had shorter disease duration (p = 0.006) compared to those who accepted follow-up.

CONCLUSION

A first CV screening consultation was accepted by most patients with RA, while only every other patient with high to very high CV risk adhered to a follow-up screening consultation. Neither measures of disease impact nor lifestyle factors were associated with adherence. Further studies are needed to explore the patients' motivation, barriers and facilitators for adherence or non-adherence to a follow-up consultation.

Cardiovascular disease risk in early rheumatoid arthritis: the impact of cartilage oligomeric matrix protein (COMP) and disease activity

BACKGROUND

To investigate whether baseline serum cartilage oligomeric matrix protein (COMP), patient characteristics, traditional cardiovascular disease (CVD) risk factors and disease activity over time predict CVD, in early rheumatoid arthritis (RA).

METHODS

This study included patients with early RA (< 12 months disease duration) (n = 233) recruited 1995-2005. Potential predictors of CVD and coronary artery disease (CAD) were assessed using Cox regression.

RESULTS

A first ever diagnosis of CVD occurred in 70 patients, and CAD in 52. Age, sex, hypertension and diabetes predicted CVD and CAD. COMP was associated with increased risk of CVD and CAD [crude hazard ratios (HRs) per SD 1.45; 95% CI 1.17-1.80 and 1.51; 95% CI 1.18-1.92, respectively]. When adjusted for age, sex, hypertension, diabetes and ESR, results where similar but did not reach significance [HRs 1.32, 95% CI 0.99-1.74 and 1.35, 95% CI 0.99-1.86]. Baseline disease activity did not independently predict CVD. High DAS28 (> 5.1) at two years was associated with increased risk of subsequent CVD [adjusted HR 2.58; 95% CI 1.10-6.04] and CAD. ESR and CRP at two years as well as cumulative disease activity over 2 years independently predicted CVD and CAD.

CONCLUSION

COMP may be a novel predictor of CVD and CAD in RA. Active disease two years after RA diagnosis, as well as cumulative disease activity, was associated with increased risk of CVD and CAD, independent of traditional CVD risk factors. Awareness of the particularly increased CVD risk among difficult to treat patients is important in order to further reduce CVD in RA.

The Influence of Rheumatoid Arthritis and Osteoarthritis on the Occurrence of Arterial Hypertension: An 8-Year Prospective Clinical Observational Cohort Study

Rheumatoid arthritis (RA) increases the risk of cardiovascular mortality and morbidity, including a 50-60% increased risk of cardiovascular disease (CVD). Arterial hypertension (HT) is considered the major contributing risk factor for CVD development in RA patients. In this investigation, we compared the incidence and prevalence of HT between RA and osteoarthritis (OA) and the influence of HT on CVD development in CVD-naive patients in both groups. This was a prospective clinical cohort investigation with an 8-year follow-up period. A total of 201 participants, 124 with RA (investigation group) and 77 with OA (control group), without diagnosed CVD or symptomatic heart failure were included. After selection according to inclusion and exclusion criteria, both groups underwent initial and final visits, and the investigation group underwent annual visits to assess disease activity. Case report forms were completed for each visit. The obtained data were analyzed by a statistician. No difference in the incidence or prevalence of HT was found between the investigation and control groups. No difference in the prevalence of HT was reported between the study groups and age-standardized data from the general population. The investigation group had a higher incidence of CVD than the control group. RA participants with long-term remission had a marginally lower HT prevalence. Although previous studies reported a higher HT prevalence in RA than in OA and the general population, our findings did not support this. The RA group had a higher incidence of CVD, but it is possible that optimal disease control with long-term remission could reduce HT incidence and prevalence while also having beneficial effects on other cardiovascular risk factors (CV) and, consequently, CVD occurrence.

The role of glucocorticoids in increasing cardiovascular risk

Introduction

Different studies provide conflicting evidence regarding the potential for glucocorticoids (GCs) to increase the risk of cardiovascular diseases. This study performed a systematic review and meta-analysis to determine the correlation between GCs and cardiovascular risk, including major adverse cardiovascular events (MACE), death from any cause, coronary heart disease (CHD), heart failure (HF), and stroke.

Methods

We performed a comprehensive search in PubMed and Embase (from inception to June 1, 2022). Studies that reported relative risk (RR) estimates with 95% confidence intervals (CIs) for the associations of interest were included.

Results

A total of 43 studies with 15,572,512 subjects were included. Patients taking GCs had a higher risk of MACE (RR = 1.27, 95% CI: 1.15-1.40), CHD (RR = 1.25, 95% CI: 1.11-1.41), and HF (RR = 1.92, 95% CI: 1.51-2.45). The MACE risk increased by 10% (95% CI: 6%-15%) for each additional gram of GCs cumulative dose or by 63% (95% CI: 46%-83%) for an additional 10 μg daily dose. The subgroup analysis suggested that not inhaled GCs and current GCs use were associated with increasing MACE risk. Similarly, GCs were linked to an increase in absolute MACE risk of 13.94 (95% CI: 10.29-17.58) cases per 1,000 person-years.

Conclusions

Administration of GCs is possibly related with increased risk for MACE, CHD, and HF but not increased all-cause death or stroke. Furthermore, it seems that the risk of MACE increased with increasing cumulative or daily dose of GCs.

Disease-modifying anti-rheumatic drugs associated with different diabetes risks in patients with rheumatoid arthritis

OBJECTIVES

Patients with rheumatoid arthritis are prone to developing diabetes, which may lead to various sequelae and even cardiovascular diseases, the most common cause of death in such patients. Previous research has shown that some rheumatoid arthritis treatments may help prevent the development of diabetes. This study aimed to investigate whether patients using disease-modifying anti-rheumatic drugs (DMARDs) may have different levels of risk for diabetes and to analyse other risk factors for diabetes.

METHODS

This cohort study used data from the Chang Gung Research Database. 5530 adults with rheumatoid arthritis but without diabetes were eligible for the analysis. The endpoint of this study was new-onset diabetes, defined as an HbA1c value ≥7% during follow-up. The entire follow-up period was divided into monthly subunits. These 1-month units were then divided into methotrexate (MTX) monotherapy, any biological DMARDs (bDMARDs), MTX combination, other conventional DMARDs (cDMARDs) and non-DMARDs.

RESULTS

A total of 546 participants (9.87%) developed diabetes between 2001 and 2018. The risk of diabetes was significantly lower in the bDMARD periods (HR 0.51; 95% CI 0.32 to 0.83), MTX combination periods (HR 0.50; 95% CI 0.32 to 0.78) and other cDMARD periods (HR 0.56; 95% CI 0.37 to 0.84) than in the MTX monotherapy periods. Individual drug analysis showed that hydroxychloroquine (HR 0.52; 95% CI 0.42 to 0.65) reduced the risk of diabetes. Tumour necrosis factor-α inhibitors (HR 0.69; 95% CI 0.46 to 1.03) tended to be protective.

CONCLUSION

Patients with rheumatoid arthritis may have different levels of risk of diabetes depending on the treatment options.

Remotely Supervised Weight Loss and Exercise Training to Improve Rheumatoid Arthritis Cardiovascular Risk: Rationale and Design of the Supervised Weight Loss Plus Exercise Training-Rheumatoid Arthritis Trial

Patients with rheumatoid arthritis (RA) remain at an increased risk for cardiovascular disease (CVD) and mortality. RA CVD results from a combination of traditional risk factors and RA-related systemic inflammation. One hypothetical means of improving overall RA CVD risk is through reduction of excess body weight and increased physical activity. Together, weight loss and physical activity can improve traditional cardiometabolic health through fat mass loss, while also improving skeletal muscle health. Additionally, disease-related CVD risk may improve as both fat mass loss and exercise reduce systemic inflammation. To explore this hypothesis, 26 older persons with RA and overweight/obesity will be randomized to 16 weeks of a usual care control arm or to a remotely Supervised Weight Loss Plus Exercise Training (SWET) program. A caloric restriction diet (targeting 7% weight loss) will occur via a dietitian-led intervention, with weekly weigh-ins and group support sessions. Exercise training will consist of both aerobic training (150 minutes/week moderate-to-vigorous exercise) and resistance training (twice weekly). The SWET remote program will be delivered via a combination of video conference, the study YouTube channel, and study mobile applications. The primary cardiometabolic outcome is the metabolic syndrome Z score, calculated from blood pressure, waist circumference, high-density lipoprotein cholesterol, triglycerides, and glucose. RA-specific CVD risk will be assessed with measures of systemic inflammation, disease activity, patient-reported outcomes, and immune cell function. The SWET-RA trial will be the first to assess whether a remotely supervised, combined lifestyle intervention improves cardiometabolic health in an at-risk population of older individuals with RA and overweight/obesity.

Cardiovascular Disease and Cardiac Imaging in Inflammatory Arthritis

Cardiovascular morbidity and mortality are more prevalent in inflammatory arthritis (IA) compared to the general population. Recognizing the importance of addressing this issue, the European League Against Rheumatism (EULAR) published guidelines on cardiovascular disease (CVD) risk management in IA in 2016, with plans to update going forward based on the latest emerging evidence. Herein we review the latest evidence on cardiovascular disease in IA, taking a focus on rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis, reflecting on the scale of the problem and imaging modalities to identify disease. Evidence demonstrates that both traditional CVD factors and inflammation contribute to the higher CVD burden. Whereas CVD has decreased with the newer anti-rheumatic treatments currently available, CVD continues to remain an important comorbidity in IA patients calling for prompt screening and management of CVD and related risk factors. Non-invasive cardiovascular imaging has been attracting much attention in view of the possibility of detecting cardiovascular lesions in IA accurately and promptly, even at the pre-clinical stage. We reflect on imaging modalities to screen for CVD in IA and on the important role of rheumatologists and cardiologists working closely together.

Atherosclerotic Cardiovascular Risk Stratification in the Rheumatic Diseases:: An Integrative, Multiparametric Approach

Cardiovascular disease (CVD) risk is increased in most inflammatory rheumatic diseases (IRDs), reiterating the role of inflammation in the initiation and progression of atherosclerosis. An inverse association of CVD risk with body weight and lipid levels has been described in IRDs. Coronary artery calcium scores, plaque burden and characteristics, and carotid plaques on ultrasound optimize CVD risk estimate in IRDs. Biomarkers of cardiac injury, autoantibodies, lipid biomarkers, and cytokines also improve risk assessment in IRDs. Machine learning and deep learning algorithms for phenotype and image analysis hold promise to improve CVD risk stratification in IRDs.

Time Trends of Cardiovascular Disease in the General Population and Inflammatory Arthritis

Cardiovascular diseases (CVDs) are the leading causes of death in the world, but declining trends for cardiovascular (CV) mortality and morbidity have been observed during the last decades. Reports on secular trends regarding the excess CV mortality and morbidity in rheumatoid arthritis show diverging results. Data support that also patients with inflammatory arthritis have benefited from improved treatment and prevention for CVD, which can be observed, for example, in decreased case fatality after CV event. However, several recent studies indicate a remaining excess CV risk in patients with inflammatory arthritis.

Hormonal and Reproductive Factors in Relation to Cardiovascular Events in Women with Early Rheumatoid Arthritis

Hormonal and reproductive factors affect the risk for cardiovascular events (CVE) in the general population. Although the risk of CVE is increased in rheumatoid arthritis (RA), the knowledge about the impact of hormonal factors for CVE in RA is sparse. Female postmenopausal patients ≤80 years with early RA were consecutively included in this observational study (n = 803) between 1 January 1996 until 31 December 2017. Questionnaires regarding hormonal factors were distributed from the index date. Data regarding CVE were obtained from the Swedish National Health Register and Cause of Death Register. Associations between CVE and hormonal factors were analyzed using Cox proportional hazard regression. Of the postmenopausal women, 64 women had a CVE after RA onset. The time period from menopause to RA onset was significantly longer for CVE cases with higher proportion of postmenopausal women. In Cox proportional hazard regression models, years from last childbirth and multiparity were associated with higher CVE risk. Adjustments for traditional risk factors did not affect the results except for hypertension. RA onset after menopause and a longer duration from menopause until onset increased the CVE risk. Multiparity was associated with higher CVE risk whilst oral contraceptives decreased the risk. These results can contribute to identification of high-risk patients for CVE beyond traditional risk factors.

Construction of Rheumatoid Arthritis Risk Prediction and Medical Image Applications from Rheumatoid Factor Levels

Objective

To study the value of rheumatoid factor (RF) levels in the risk assessment of rheumatoid arthritis (RA) and combined hypertension and diabetes mellitus (DM) and construct RA risk prediction and medical image applications from rheumatoid factor levels.

Methods

A total of 249 RA patients who were treated in the First People's Hospital of Yunnan Province, and another 149 non-RA people were selected as the controls. The clinical data and the detection results of serum circulating RF_IgA, RF_IgG, and RF_IgM were collected. The receiver operating curve (ROC) and logistic regression were used to analyze the value of RF levels in the risk assessment of RA and combined hypertension and DM.

Results

After adjusting for age, BMI, smoking, drinking, hypertension, and diabetes, logistic regression analysis showed that RF_IgA positive, RF_IgG positive, and RF_IgM positive were all independent risk factors for RA (P < 0.05). The area under the curve (AUC) of circulating RF_IgA, RF_IgG, and RF_IgM levels in predicting RA was 0.79 (95% CI: 0.74-0.83, P < 0.001), 0.73 (95% CI: 0.68-0.78, P < 0.001), and 0.87 (95% CI: 0.84-0.91, P < 0.001), respectively. The AUC for predicting RA was 0.88 (95% CI: 0.85-0.92, P < 0.001) when combined detection of circulating RF_IgA, RF_IgG, and RF_IgM levels in peripheral blood. After adjusting for age and sex, logistic regression analysis showed that RF_IgA positive, RF_IgG positive, and RF_IgM positive were not independent risk factors for DM in RA patients (P > 0.05).

Conclusion

The levels of serum circulating RF_IgA, RF_IgG, and RF_IgM are valuable indicators for predicting the risk of RA, but not for the risk of RA complicated with hypertension and DM.

Short-term, intermediate-term and long-term risks of acute coronary syndrome in cohorts of patients with RA starting biologic DMARDs: results from four Nordic countries

OBJECTIVES

To compare the 1-year, 2-year and 5-year incidences of acute coronary syndrome (ACS) in patients with rheumatoid arthritis (RA) starting any of the biologic disease-modifying antirheumatic drugs (bDMARDs) currently available in clinical practice and to anchor these results with a general population comparator.

METHODS

Observational cohort study, with patients from Denmark, Finland, Norway and Sweden starting a bDMARD during 2008-2017. Time to first ACS was identified through register linkages. We calculated the 1-year, 2-year and 5-year incidence rates (IR) (on drug and ever since treatment start) and used Cox regression (HRs) to compare ACS incidences across treatments taking ACS risk factors into account. Analyses were further performed separately in subgroups defined by age, number of previous bDMARDs and history of cardiovascular disease. We also compared ACS incidences to an individually matched general population cohort.

RESULTS

24 083 patients (75% women, mean age 56 years) contributing 40 850 treatment courses were included. During the maximum (5 years) follow-up (141 257 person-years (pyrs)), 780 ACS events occurred (crude IR 5.5 per 1000 pyrs). Overall, the incidence of ACS in RA was 80% higher than that in the general population. For all bDMARDs and follow-up definitions, HRs were close to 1 (etanercept as reference) with the exception of the 5-year risk window, where signals for abatacept, infliximab and rituximab were noted.

CONCLUSION

The rate of ACS among patients with RA initiating bDMARDs remains elevated compared with the general population. As used in routine care, the short-term, intermediate-term and longer-term risks of ACS vary little across individual bDMARDs.

Managing Cardiovascular Risk in Patients with Rheumatic Disease

Individuals with rheumatoid arthritis, systemic lupus erythematosus, or gout have increased risk of cardiovascular disease (CVD) compared with the general population. This risk relates to a combination of traditional cardiovascular risk factors and disease-specific factors. Screening for CVD is important because CVD contributes to significant morbidity and mortality. Management includes tight control of disease activity to reduce inflammation, but with care to minimize use of nonsteroidal anti-inflammatory drugs and prolonged courses of high-dose corticosteroids. Traditional cardiovascular risk factors should be managed with a combination of lifestyle interventions and pharmacotherapy. The decision to start antihypertensive and lipid-lowering therapy should be based on individual CVD risk.

Trends in the occurrence of ischaemic heart disease over time in rheumatoid arthritis: 1821 patients from 1972 to 2017

OBJECTIVE

To evaluate trends of acute myocardial infarction (AMI) and ischaemic heart disease (IHD) in rheumatoid arthritis (RA) patients compared with the general population over time.

METHOD

We performed a retrospective cohort study of 1821 RA patients diagnosed from 1972 to 2013. Aggregated counts of the total population of the same county (Hordaland, Norway) and period were used for comparison. Information on AMI and IHD events was obtained from hospital patient administrative systems or cardiovascular registries. We estimated incidence rates and excess of events [standardized event ratio (SER) with 95% confidence interval (CI)] compared with the general population by Poisson regression.

RESULTS

There was an average annual decline of 1.6% in age- and gender-adjusted AMI incidence rates from 1972 to 2017 (p < 0.035). The difference in events (excess events) in RA patients compared with the general population declined on average by 1.3% per year for AMI and by 2.3% for IHD from 1972 to 2014. There were no significant excess AMI (SER 1.05, 95% CI 0.82-1.35) or IHD events (SER 1.02, 95% CI 0.89-1.16) for RA patients diagnosed after 1998 compared with the general population.

CONCLUSION

Incidence rates and excess events of AMI and IHD in RA patients declined from 1972 to 2017. There were no excess AMI or IHD events in RA patients diagnosed after 1998 compared with the general population.

The Complex Role of C-Reactive Protein in Systemic Lupus Erythematosus

C-reactive protein (CRP) is well-known as a sensitive albeit unspecific biomarker of inflammation. In most rheumatic conditions, the level of this evolutionarily highly conserved pattern recognition molecule conveys reliable information regarding the degree of ongoing inflammation, driven mainly by interleukin-6. However, the underlying causes of increased CRP levels are numerous, including both infections and malignancies. In addition, low to moderate increases in CRP predict subsequent cardiovascular events, often occurring years later, in patients with angina and in healthy individuals. However, autoimmune diseases characterized by the Type I interferon gene signature (e.g., systemic lupus erythematosus, primary Sjögren’s syndrome and inflammatory myopathies) represent exceptions to the general rule that the concentrations of CRP correlate with the extent and severity of inflammation. In fact, adequate levels of CRP can be beneficial in autoimmune conditions, in that they contribute to efficient clearance of cell remnants and immune complexes through complement activation/modulation, opsonization and phagocytosis. Furthermore, emerging data indicate that CRP constitutes an autoantigen in systemic lupus erythematosus. At the same time, the increased risks of cardiovascular and cerebrovascular diseases in patients diagnosed with systemic lupus erythematosus and rheumatoid arthritis are well-established, with significant impacts on quality of life, accrual of organ damage, and premature mortality. This review describes CRP-mediated biological effects and the regulation of CRP release in relation to aspects of cardiovascular disease and mechanisms of autoimmunity, with particular focus on systemic lupus erythematosus.

Rheumatoid Arthritis and Cardiovascular Risk: Retrospective Matched-Cohort Analysis Based on the RECORD Study of the Italian Society for Rheumatology

Background: Rheumatoid arthritis (RA) is associated with an increase in cardiovascular (CV) risk. This issue maybe not only explained by a genetic component, as well as by the traditional CV risk factors, but also by an underestimation and undertreatment of concomitant CV comorbidities.

Method: This was a retrospective matched-cohort analysis in the Italian RA real-world population based on the healthcare-administrative databases to assess the CV risk factors and incidence of CV events in comparison with the general population. Persistence and adherence to the CV therapy were also evaluated in both groups.

Results: In a RA cohort (N = 21,201), there was a greater prevalence of hypertension and diabetes with respect to the non-RA subjects (N = 249,156) (36.9 vs. 33.4% and 10.2 vs. 9.6%, respectively), while dyslipidemia was more frequent in the non-RA group (15.4 vs. 16.5%). Compared with a non-RA cohort, the patients with RA had a higher incidence of atrial fibrillation (incidence rate ratio, IRR 1.28), heart failure (IRR 1.53), stroke (IRR 1.19), and myocardial infarction (IRR 1.48). The patients with RA presented a significantly lower persistence rate to glucose-lowering and lipid-lowering therapies than the controls (odds ratio, OR 0.73 [95% CI 0.6–0.8] and OR 0.82 [0.8–0.9], respectively). The difference in the adherence to glucose-lowering therapy was significant (OR 0.7 [0.6–0.8]), conversely no statistically significant differences emerged regarding the adherence to lipid-lowering therapy (OR 0.89 [95% CI 0.8–1.0]) and anti-hypertensive therapy (OR 0.96 [95% CI 0.9–1.0]).

Conclusion: The patients with RA have a higher risk of developing CV events compared with the general population, partially explained by the excess and undertreatment of CV risk factors.

Improvement of Inflammation and Pain after Three Months' Exclusion Diet in Rheumatoid Arthritis Patients

Introduction: Rheumatoid arthritis (RA) is a chronic systemic autoimmune disease affecting the synovial joints and causing severe disability. Environmental and lifestyle factors, including diet, have been proposed to play a role in the onset and severity of RA. Dietary manipulation may help to manage the symptoms of RA by lowering inflammation and potentially decreasing pain. Methods: In 40 patients with long-standing RA with stable symptoms and treated with conventional (c-) and biological (b-) disease modifying anti-rheumatic drugs (DMARDs), the effect of a 3-month diet avoiding meat, gluten, and lactose (and all dairy products; privative diet) was evaluated in comparison with a control balanced diet including those foods. Both diets were designed to reduce weight since all patients were overweight or obese. Patients were randomly assigned to one of the diets, and RA was clinically assessed at Time 0 (T0), through the Visual Analogue Scale (VAS), for pain, and the Disease Activity Score of 28 joints (DAS 28) for RA activity. Patients were also administered the Short Form Health survey (SF-36) and the Health Assessment Questionnaire (HAQ). At T0, a blood sample was collected for laboratory tests and adipokines measurements, and anthropometric measurements were compared. These evaluations were repeated at the end of the 3 months’ dietary regimens. Results: A significant decrease in VAS and the improvement of the overall state of physical and mental health, assessed through SF-36, was observed in patients assigned to the privative diet. Both dietary regimens resulted in the improvement of quality of life compared to baseline values; however, the change was significant only for the privative diet. With either diet, patients showed significant decreases in body weight and body mass index, with a reduction in waist and hips circumference and lower basal glucose and circulating leptin levels. A privative diet was also able to significantly reduce systolic (p = 0.003) and diastolic (p = 0.025) arterial pressure. The number of circulating leukocytes and neutrophils, and the level of hs-C-Reactive Protein also decreased after 3 months of the meat-, lactose-, and gluten-free diet. Conclusions: Our results suggest that a privative diet can result in a better control of inflammation in RA patients under stable optimized drug treatment.

The impact of statins on coronary atherosclerosis progression and long-term cardiovascular disease risk in rheumatoid arthritis

OBJECTIVES

To evaluate whether statins lower cardiovascular disease (CVD) risk in rheumatoid arthritis (RA) and if tentative benefits are related to changes in coronary plaque burden or composition.

METHODS

In an observational cohort study, 150 patients without CVD underwent coronary atherosclerosis evaluation (total, noncalcified, partially and fully calcified plaque) with computed tomography angiography. Prespecified cardiovascular events including cardiac death, myocardial infarction, unstable angina, revascularization, stroke, claudication, and heart failure were prospectively recorded. Change in plaque burden and composition was re-assessed in 102 patients within 6.9±0.3 years.

RESULTS

Time varying statin therapy, modeled using inverse probability treatment and censoring weights, did not significantly attenuate CVD risk in RA overall (adjusted- OR = 0.39 [95%CI=0.15-1.07], p = 0.067). However, statins associated with lower CVD risk in patients with baseline CRP>0.5mg/dL (adjusted-OR=0.09 [95%CI=0.03-0.30], p < 0.001) but not in those with CRP<0.5mg/dL (p-interaction=0.023), after controlling for Framingham-CVD score and time-varying bDMARD use. In patients treated with statin >50% of follow-up time, CRP did not associate with new plaque formation (adjusted-OR=0.42 [95%CI=0.09-1.94]), in contrast to statin-naïve (adjusted-OR=1.89 [95%CI=1.41-2.54]) and statin-treated <50% time (adjusted-OR=1.41 [95%CI=1.03-1.95], p-interaction=0.029). Statin therapy >50% follow-up time predicted dissipation (adjusted-OR=5.84 [95%CI=1.29-26.55]) and calcification of prevalent noncalcified lesions (adjusted-OR=4.16 [95%CI=1.11-15.54]), as well as new calcified plaque formation in segments without baseline plaque (adjusted-OR=2.84 [95%CI=1.09-7.41]).

CONCLUSION

Statin therapy associated with lower long-term cardiovascular risk in RA patients with higher inflammation. Moreover, statin therapy modified the impact of inflammation on new coronary plaque formation and predicted both regression and calcification of prevalent noncalcified lesions.

Comorbidities at diagnosis of rheumatoid arthritis: a population-based case-control study

OBJECTIVES

Comorbidities contribute to the morbidity and mortality in RA, and are thus important to capture and treat early. In contrast to the well-studied comorbidity risks in established RA, less is known about the comorbidity pattern up until diagnosis of RA. We therefore compared whether the occurrence of defined conditions, and the overall comorbidity burden at RA diagnosis, is different from that in the general population, and if it differs between seropositive and seronegative RA.

METHODS

Using Swedish national clinical and demographic registers, we identified new-onset RA patients (n = 11 086), and matched (1:5) to general population controls (n = 54 813). Comorbidities prior to RA diagnosis were identified in the Patient and Prescribed Drug Registers, and compared using logistic regression.

RESULTS

At diagnosis of RA, respiratory (odds ratio (OR) = 1.58, 95% CI: 1.44, 1.74), endocrine (OR = 1.39, 95% CI: 1.31, 1.47) and certain neurological diseases (OR = 1.73, 95% CI: 1.59, 1.89) were more common in RA vs controls, with a similar pattern in seropositive and seronegative RA. In contrast, psychiatric disorders (OR = 0.87, 95% CI: 0.82, 0.92) and malignancies (OR = 0.88, 95% CI: 0.79, 0.97) were less commonly diagnosed in RA vs controls. The comorbidity burden was slightly higher in RA patients compared with controls (P <0.0001).

CONCLUSION

We found several differences in comorbidity prevalence between patients with new-onset seropositive and seronegative RA compared with matched controls from the general population. These findings are important both for our understanding of the evolvement of comorbidities in established RA and for early detection of these conditions.

Tumour necrosis factor inhibitors reduce aortic stiffness progression in patients with long-standing rheumatoid arthritis

BACKGROUND

Aortic stiffness index (AoSI) has to be considered a proxy outcome measure in patients with rheumatoid arthritis (RA). The aim of this study was to comparatively describe AoSI progression in two groups of RA patients on long-term treatment with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) with or without tumour necrosis factor inhibitors (TNFi).

METHODS

AoSI was evaluated by Doppler echocardiography at the level of the aortic root, using a two-dimensional guided M-mode evaluation. Eligible participants were assessed at baseline and after 12 months. Changes in serum lipids, glucose and arterial blood pressure were assessed. All patients who did not change DMARD treatment during follow-up were consecutively selected for this study.

RESULTS

We included 107 (64 TNFi and 43 csDMARDs) RA patients. Most patients (74%) were in remission or low disease activity and had some CVD risk factors (45.8% hypertension, 59.8% dyslipidaemia, 45.3% smoking). The two groups did not differ significantly for baseline AoSI (5.95±3.73% vs 6.08±4.20%, p=0.867). Follow-up AoSI was significantly increased from baseline in the csDMARDs group (+1.00%; p<0.0001) but not in the TNFi group (+0.15%, p=0.477). Patients on TNFi had significantly lower follow-up AoSI from baseline than the csDMARDs group (-1.02%, p<0.001; ANCOVA corrected for baseline AoSI, age and systolic blood pressure). Furthermore, follow-up AoSI was significantly lower in TNFi than in csDMARDs users with an increasing number of CVD risk factors.

CONCLUSION

Long-term treatment with TNFi was associated with reduced aortic stiffness progression in patients with established RA and several CVD risk factors.

Improvement of HbA1c in Patients with Type 2 Diabetes Mellitus and Rheumatoid Arthritis Treated with bDMARDs

Objective

The aim of our study was to evaluate the possible role of biological treatments for rheumatoid arthritis (RA) in improving the glycemic profile in patients affected not only by RA but also by type 2 diabetes mellitus (2TDM).

Methods

An observational retrospective study was conducted using data from patients referred to our Rheumatology Unit. Patients with active RA despite standard DMARDs therapy and concomitant 2TDM were selected into one of five exposure groups to first-line bDMARDs (adalimumab, golimumab, etanercept, tocilizumab, sarilumab) and observed for the outcome of CRP, ESR, DAS28CRP and glycated hemoglobin (HbA1c) variations.

Results

After the start of treatment, there was a significant reduction in the values of acute phase reactants ESR and CRP (p<0.01), DAS28-CRP (p<0.01) and HbA1C (p<0.05), in the absence of any confounding factors such as a reduction in BMI or a change in steroid doses. There was no statistically significant difference between the various treatments. Anti-IL6 drugs appear to be associated with a slightly greater reduction in HbA1c values, bordering on statistical significance (p=0.047).

Conclusion

Initiation of a bDMARD appears to be associated with an improvement in concomitant 2TDM in patients with active RA, which, in the first hypothesis, is linked with a reduction of the inflammatory milieu.

Glucocorticoid use is associated with an increased risk of hypertension

OBJECTIVES

Patients with RA are frequently treated with glucocorticoids (GCs), but evidence is conflicting about whether GCs are associated with hypertension. The aim of this study was to determine whether GCs are associated with incident hypertension in patients with RA.

METHODS

A retrospective cohort of patients with incident RA and without hypertension was identified from UK primary care electronic medical records (Clinical Practice Research Datalink). GC prescriptions were used to determine time-varying GC use, dose and cumulative dose, with a 3 month attribution window. Hypertension was identified through either: blood pressure measurements >140/90 mmHg, or antihypertensive prescriptions and a Read code for hypertension. Unadjusted and adjusted Cox proportional hazards regression models were fitted to determine whether there was an association between GC use and incident hypertension.

RESULTS

There were 17 760 patients in the cohort. A total of 7421 (42%) were prescribed GCs during follow-up. The incident rate of hypertension was 64.1 per 1000 person years (95% CI: 62.5, 65.7). The Cox proportional hazards model indicated that recent GC use was associated with a 17% increased hazard of hypertension (hazard ratio 1.17; 95% CI: 1.10, 1.24). When categorized by dose, only doses above 7.5 mg were significantly associated with hypertension. Cumulative dose did not indicate a clear pattern.

CONCLUSION

Recent GC use was associated with incident hypertension in patients with RA, in particular doses ≥7.5 mg were associated with hypertension. Clinicians need to consider cardiovascular risk when prescribing GCs, and ensure blood pressure is regularly monitored and treated where necessary.

Biologics and atherosclerotic cardiovascular risk in rheumatoid arthritis: a review of evidence and mechanistic insights

Introduction: Cardiovascular disease is a leading comorbidity in rheumatoid arthritis. Timely introduction of biologic therapies in a treat-to-target approach has optimized disease-related outcomes and attenuated accrual of comorbidities, including cardiovascular risk.Areas covered: A literature search in MEDLINE (via PubMed) was performed between January 2009 and November 2020. This manuscript explores recent developments in atherosclerotic cardiovascular risk in RA compared with non-RA individuals; it synopsizes differences in vascular function and inflammation, prevalence, burden, vulnerability, and progression of atherosclerotic plaque and their underlying cellular and molecular mechanisms. Finally, it reviews the recent literature on cardioprotective benefits of biologics and draws mechanistic links with inhibition of new plaque formation, stabilization of high-risk lesions and improvement in endothelial function, arterial stiffness, lipid metabolism, and traditional cardiac risk factors.Expert opinion: Increasing evidence points to a solid cardioprotective influence of earlier, longer, and ongoing use of biologic treatments in RA. Nevertheless, the precise mechanistic effects of plaque progression and remodeling, vascular stiffness, endothelial dysfunction, lipid metabolism, and traditional cardiac risk factors are less rigorously characterized.

Isotemporal Substitution of Time Between Sleep and Physical Activity: Associations With Cardiovascular Risk Factors in Early Rheumatoid Arthritis

OBJECTIVE

We aimed to determine relationships between objectively measured nightly sleep, sedentary behavior (SB), light physical activity (LPA), and moderate to vigorous physical activity (MVPA) with risk factors for cardiovascular disease (CVD) in patients with early rheumatoid arthritis (RA). Furthermore, we aimed to estimate consequences for these risk factors of theoretical displacements of 30 minutes per day in one behavior with the same duration of time in another.

METHODS

This cross-sectional study included 78 patients with early RA. Nightly sleep, SB, LPA, and MVPA were assessed by a combined heart rate and accelerometer monitor. Associations with risk factors for CVD were analyzed using linear regression models and consequences of reallocating time between the behaviors by isotemporal substitution modeling.

RESULTS

Median (Q1-Q3) nightly sleep duration was 4.6 (3.6-5.8) hours. Adjusted for monitor wear time, age, and sex, 30-minutes-longer sleep duration was associated with favorable changes in the values β (95% confidence interval [CI]) for waist circumference by -2.2 (-3.5, -0.9) cm, body mass index (BMI) by -0.9 (-1.4, -0.4) kg/m2 , body fat by -1.5 (-2.3, -0.8)%, fat-free mass by 1.6 (0.8, 2.3)%, sleeping heart rate by -0.8 (-1.5, -0.1) beats per minute, and systolic blood pressure by -2.5 (-4.0, -1.0) mm Hg. Thirty-minute decreases in SB, LPA, or MVPA replaced with increased sleep was associated with decreased android fat and lower systolic blood pressure levels. Replacement of SB or LPA with MVPA yielded lower BMIs.

CONCLUSION

Shorter sleep during the night is common among patients with early RA and is associated with adverse risk factors for CVD.

Managing Cardiovascular Risk in Patients with Rheumatic Disease

Individuals with rheumatoid arthritis, systemic lupus erythematosus, or gout have increased risk of cardiovascular disease (CVD) compared with the general population. This risk relates to a combination of traditional cardiovascular risk factors and disease-specific factors. Screening for CVD is important because CVD contributes to significant morbidity and mortality. Management includes tight control of disease activity to reduce inflammation, but with care to minimize use of nonsteroidal anti-inflammatory drugs and prolonged courses of high-dose corticosteroids. Traditional cardiovascular risk factors should be managed with a combination of lifestyle interventions and pharmacotherapy. The decision to start antihypertensive and lipid-lowering therapy should be based on individual CVD risk.

Patients with rheumatoid arthritis have impaired long-term outcomes after myocardial infarction - a nationwide case-control registry study

Objective

To investigate the long-term outcomes of patients with RA after myocardial infarction (MI).

Methods

All-comer, real-life MI patients with RA (n = 1614, mean age 74 years) were retrospectively compared with propensity score (1:5) matched MI patients without RA (n = 8070) in a multicentre, nationwide, cohort register study in Finland. The impact of RA duration and the usage of corticosteroids and antirheumatic drugs on RA patients’ outcomes were also studied. The median follow-up was 7.3 years.

Results

RA was associated with an increased 14-year mortality risk after MI compared with patients without RA [80.4% vs 72.3%; hazard ratio (HR) 1.25; CI: 1.16, 1.35; P <0.0001]. Patients with RA were at higher risk of new MI (HR 1.22; CI: 1.09, 1.36; P =0.0001) and revascularization (HR 1.28; CI: 1.10, 1.49; P =0.002) after discharge from index MI. Cumulative stroke rate after MI did not differ between RA and non-RA patients (P =0.322). RA duration and corticosteroid usage before MI, but not use of methotrexate or biologic antirheumatic drugs, were independently associated with higher mortality (P <0.001) and new MI (P =0.009). A higher dosage of corticosteroids prior to MI was independently associated with higher long-term mortality (P =0.002) and methotrexate usage with lower stroke rate (P =0.034). Serological status of RA was not associated with outcomes.

Conclusion

RA is independently associated with poorer prognosis after MI. RA duration and corticosteroid usage and dosage were independent predictors of mortality after MI in RA. Special attention is needed for improvement of outcomes after MI in this vulnerable population.

Risk factors for hypertension in rheumatoid arthritis patients-A systematic review

INTRODUCTION

Rheumatoid arthritis is frequently associated with hypertension, which has been shown to increase the risk of cardiovascular disease in these patients. The aim of this systematic review was to explore demographic, behavioural or clinical factors including medication use, associated with incident hypertension in rheumatoid arthritis.

METHODS

MEDLINE and Scopus were searched for eligible studies that longitudinally investigated incident hypertension or changes in blood pressure (BP) in rheumatoid arthritis patients. Publications were screened by two reviewers according to predetermined inclusion and exclusion criteria. The quality of included studies was assessed via the Newcastle Ottawa Scale and Cochrane Risk of Bias Tool.

RESULTS

Fourteen studies were deemed eligible and included in this review. The proportion of female subjects ranged from 12 to 87% and the mean age ranged from 47 to 61 years. Regular exercise was associated with a decrease in systolic BP, p = 0.021. Methotrexate was associated with decreased risk of hypertension in two studies. LEF was associated with increased BP in two studies. COX-2 inhibitors were associated with systolic BP and diastolic BP variability (p = 0.009, 0.039, respectively) in one study. Prednisone was found to increase BP and risk of hypertension in three studies. The risk of hypertension in patients taking biologic disease modifying anti-rheumatic drugs (DMARDs) is unclear as some studies report increased BP while others report no difference for biologic compared to conventional DMARDs.

CONCLUSION

Despite limited longitudinal studies exploring this topic, methotrexate and exercise were shown to protect against risk of hypertension in RA patients, while prednisone and COX-2 inhibitors may increase risk of hypertension.

Factors of Progression and Occurrence of Atherosclerosis in Rheumatoid Arthritis

Aim      To determine in a prospective study factors of progressive atherosclerotic lesion of blood vessels in patients with rheumatoid arthritis (RA).Material and methods  This prospective study included 124 patients with RA and suspected ischemic heart disease (IHD) and 30 patients with IHD (comparison group) aged 58 [52; 63] years. On enrollment to the study and at 3 years of follow-up, all patients underwent clinical and instrumental examination according to European and Russian guidelines for diagnosis and treatment of stable IHD (2013), including coronography as indicated. For all RA patients of the comparison group, risk factors (RF) were evaluated, including arterial hypertension, smoking, excessive body weight, family history of cardiovascular diseases (CVD), diabetes mellitus, and dyslipidemia. The following laboratory data were evaluated: blood count; biochemistry, including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), rheumatoid factor (RhF), cyclic citrullinated peptide antibodies, and high-sensitivity C-reactive protein (hsCRP). Proinflammatory cytokines, including interleukin (IL)-1β, IL-6, and tumor necrosis factor-α (TNF- α), were measured in RA patients once, at 3 years of follow-up.Results Incidence of FRs for CVD was similar in RA patients and in the comparison group. Median RA duration before inclusion into the study was 11 years, and median DAS28 index score was 3.8. Incidence of dyslipidemia due to increased TC, LDL-C, and HDL-C was higher for RA patients at baseline. The LDL-C goal (&lt;1.8 mmol/l) was achieved only in 3 (10 %) patients of the comparison group and 10 (8 %) RA patients. RA patients had higher levels of the inflammation indexes, hsCRP (0.75 mg/dl vs. 0.16 mg/dl; p&lt;0.05) and erythrocyte sedimentation rate (ESR) (15 mm/h vs. 11.5 mm/h; p&lt;0.05). In the RA group at baseline, atherosclerotic plaques with carotid artery (CTA) stenosis of 20% or more were found in 94 (77 %) patients; in 3 of them, CA stenosis was &gt;50%. Patients with RA frequently had unchanged or slightly changed coronary arteries (CA) (47% of patients), and less frequently they had hemodynamically significant multi-arterial coronary atherosclerotic lesions (7 % vs. 57 % of patients in comparison group). At 37.5 months, 21 (23 %) of 94 RA patients had progressive atherosclerosis in CA and/or CTA; 12 (13 %) RA patients had only progressive CA atherosclerosis; 7 (8 %) had only progressive CTA atherosclerosis; and 2 (2 %) had simultaneous progression of CA and CTA atherosclerosis. Two groups of RA patients were formed, with the progression of atherosclerosis (n=21) and without the progression of atherosclerosis (n=69). RFs for the development/progression of atherosclerosis in RA patients included smoking, family history of CVD, and duration of the disease. Levels of lipids did not differ. Levels of proinflammatory cytokines (IL-1β, IL-6, TNF-α) were higher in RA patients with progressive atherosclerosis. No effects of the anti-rheumatic therapy on the progression of atherosclerosis were observed.Conclusion      Progression of atherosclerosis in RA remains in disease with low and moderate activity during the anti-rheumatic and hypolipidemic treatment. The development of atherosclerosis in RA is determined by lipid, inflammatory, and immune disorders.

Similar lipid level changes in early rheumatoid arthritis patients following 1-year treat-to-target strategy with adalimumab plus methotrexate versus placebo plus methotrexate: secondary analyses from the randomised controlled OPERA trial

To compare changes in low-density lipoprotein cholesterol and other lipids in patients with rheumatoid arthritis (RA) randomised to a 1-year treat-to-target strategy with either adalimumab plus methotrexate or placebo plus methotrexate. Prespecified secondary analyses from the OPERA trial, where 180 early and treatment-naïve RA patients received methotrexate 20 mg once weekly in combination with either placebo or subcutaneous adalimumab 40 mg every other week. Serum lipid levels were measured at baseline and after 1 year. Changes in lipid levels were analysed using mixed linear models based on the intention-to-treat (ITT) population. Overall, 174 patients were included in the ITT population (adalimumab plus methotrexate n = 86; placebo plus methotrexate n = 88). Differences between changes in lipid levels were low-density lipoprotein cholesterol 0.18 mmol/l [95% CI - 0.05 to 0.42], total cholesterol 0.27 mmol/l [- 0.002 to 0.54], high-density lipoprotein cholesterol 0.05 mmol/l [- 0.06 to 0.15], triglycerides 0.11 mmol/l [- 0.08 to 0.29], very-low-density lipoprotein cholesterol 0.03 mmol/l [- 0.05 to 0.12], and non-high-density lipoprotein cholesterol 0.22 mmol/l [- 0.02 to 0.46]. In early RA patients treated to tight control of inflammation over a period of 1 year with either adalimumab plus methotrexate or placebo plus methotrexate, changes in lipid levels were similar. Trial registration number: NCT00660647.

The Lipid Paradox as a Metabolic Checkpoint and Its Therapeutic Significance in Ameliorating the Associated Cardiovascular Risks in Rheumatoid Arthritis Patients

While the most common manifestations associated with rheumatoid arthritis (RA) are synovial damage and inflammation, the systemic effects of this autoimmune disorder are life-threatening, and are prevalent in 0.5–1% of the population, mainly associated with cardiovascular disorders (CVDs). Such effects have been instigated by an altered lipid profile in RA patients, which has been reported to correlate with CV risks. Altered lipid paradox is related to inflammatory burden in RA patients. The review highlights general lipid pathways (exogenous and endogenous), along with the changes in different forms of lipids and lipoproteins in RA conditions, which further contribute to elevated risks of CVDs like ischemic heart disease, atherosclerosis, myocardial infarction etc. The authors provide a deep insight on altered levels of low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglycerides (TGs) in RA patients and their consequence on the cardiovascular health of the patient. This is followed by a detailed description of the impact of anti-rheumatoid therapy on the lipid profile in RA patients, comprising DMARDs, corticosteroids, anti-TNF agents, anti-IL-6 agents, JAK inhibitors and statins. Furthermore, this review elaborates on the prospects to be considered to optimize future investigation on management of RA and treatment therapies targeting altered lipid paradigms in patients.

Cardiovascular Risk in Rheumatoid Arthritis and Mechanistic Links: From Pathophysiology to Treatment

Rheumatoid arthritis (RA) is an autoimmune inflammatory arthritis. Inflammation, however, can spread beyond the joints to involve other organs. During the past few years, it has been well recognized that RA associates with increased risk for cardiovascular (CV) disease (CVD) compared with the general population. This seems to be due not only to the increased occurrence in RA of classical CVD risk factors and comorbidities like smoking, obesity, hypertension, diabetes, metabolic syndrome, and others but also to the inflammatory burden that RA itself carries. This is not unexpected given the strong links between inflammation and atherosclerosis and CVD. It has been shown that inflammatory cytokines which are present in abundance in RA play a significant role in every step of plaque formation and rupture. Most of the therapeutic regimes used in RA treatment seem to offer significant benefits to that end. However, more studies are needed to clarify the effect of these drugs on various parameters, including the lipid profile. Of note, although pharmacological intervention significantly helps reduce the inflammatory burden and therefore the CVD risk, control of the so-called classical risk factors is equally important. Herein, we review the current evidence for the underlying pathogenic mechanisms linking inflammation with CVD in the context of RA and reflect on the possible impact of treatments used in RA.

Cardiovascular risk estimation with 5 different algorithms before and after 5 years of bDMARD treatment in rheumatoid arthritis

BACKGROUND

Assessing cardiovascular (CV) risk represents a challenge for clinicians because more variables can impact CV risk. The aim of this study was to evaluate the change of CV risk after 5 years of biological treatment in rheumatoid arthritis (RA) patients and impact of prolonged low disease activity on 5 different CV risk algorithms.

MATERIALS AND METHODS

We estimated the CV risk, at baseline and at 5-year follow-up (FU), with the Systematic COronary Risk Evaluation(SCORE) charts, the algorithm 'Progetto Cuore', the QRISK3-2018 score, the Reynold Risk Score(RRS) and the Expanded Risk Score in RA(ERS-RA). Clinical disease activity index(CDAI) was used to define RA activity. Wilcoxon signed-rank test was used to compare CV risk scores.

RESULTS

In 110 patients with a 5-year FU on biological disease-modifying anti-rheumatic drug treatment, we observed an increase in the 10-year CV risk estimated by SCORE charts [from mean (SD) 0.9% (1.4) to 1.1% (1.5), P < .001], 'Progetto Cuore' [from mean (SD) 5.5% (7.2) to 6.2% (6.8), P < .001], QRISK3-2018 [from mean (SD) 9.3% (10.1) to 11.9% (10.8), P < .001) and RRS [from mean (SD) 5.6% (6.4) to 6.2% (7.5), P < .05], mainly due to age raise. ERS-RA highlighted a significant decrease of estimated CV risk in patients with persistent CDAI ≤ 10[from mean (SD) 9.6% (11.2) to 7.3% (6.4), P < .05], despite age increase and its impact on the CV risk score.

CONCLUSIONS

Algorithms commonly used to estimate 10-year CV risk in RA perform differently. Scores that include specific inflammatory RA-related variables seem to decrease with amelioration of disease activity. Further investigations are warranted to explore the predictive value of their changing over time.

Diet as a Modulator of Intestinal Microbiota in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic immune-driven inflammatory disease characterised by synovial inflammation, leading to progressive cartilage and bone destruction, impacting patients' functional capacity and quality of life. Patients with RA have significant differences in gut microbiota composition when compared to controls. Intestinal dysbiosis influences the intestinal barrier strength, integrity and function, and diet is considered the main environmental factor impacting gut microbiota. Over the last few years, researchers have focused on the influence of single components of the diet in the modulation of intestinal microbiota in RA rather than whole dietary patterns. In this review, we focus on how the Mediterranean diet (MD), a whole dietary pattern, could possibly act as an adjuvant therapeutic approach, modulating intestinal microbiota and intestinal barrier function in order to improve RA-related outcomes. We also review the potential effects of particular components of the MD, such as n-3 polyunsaturated fatty acids (PUFAs), polyphenols and fibre.

Acute Coronary Syndrome in a Male with Elevated Anti-Cyclic Citrullinated Peptide and no Evidence of Longstanding Rheumatoid Arthritis

A 55-year-old male, previously known to be healthy, presented to the emergency department with a 30-minute history of chest pain radiating to the upper extremities. Vital signs were within normal limits. Four days prior to this presentation, the patient presented for acute onset of polyarthritis and morning stiffness. Significantly elevated titres of anti-cyclic citrullinated peptides (anti-CCP) were found. In the emergency department, electrocardiography showed ST segment elevations in leads V1 to V5 and aVL. Cardiac enzymes were elevated. The patient underwent cardiac catheterization. A coronary angiography revealed an ectatic proximal left anterior descending (LAD) coronary artery with critical (90–99%) stenosis at the mid segment. A drug-eluting stent was successfully inserted in the LAD without any residual stenosis. Although it is known that anti-CCP positivity is a key element in the pathogenesis of atherosclerosis in RA patients, this case report adds to the existing body of literature which demonstrates that anti-CCP positivity is an independent risk factor for development of cardiovascular events.

Incident arterial vascular events in a cohort of Puerto Ricans with rheumatoid arthritis

Objective

The increased morbidity and mortality associated with cardiovascular events in patients with rheumatoid arthritis has been linked to traditional and nontraditional factors. However, these factors vary among different ethnicities. Few studies have described these features in Hispanic populations. Thus, we determined the clinical correlates of arterial vascular events in Hispanics from Puerto Rico.

Methods

A cross-sectional study was performed in a cohort of 405 Puerto Ricans with rheumatoid arthritis. Demographic parameters, health-related behaviors, clinical manifestations, disease activity (per Disease Activity Score 28), functional status (per Health Assessment Questionnaire), comorbidities, and pharmacotherapy were compared in patients with and without incident arterial vascular events. The latter was defined as the occurrence of myocardial infarction, angina pectoris, vascular procedures for coronary artery disease, stroke, or peripheral artery disease. Study groups were analyzed using bivariate and multivariate analyses.

Results

Of the total study population, 87.2% were woman. The mean age at study visit was 56.1 ± 13.9 years, and the mean disease duration was 15.0 ± 13.2 years. Arterial vascular events occurred in 43 patients (10.6%). In the multivariate analysis adjusted for age and sex, arterial hypertension, dyslipidemia, metabolic syndrome, extra-articular manifestations, higher Health Assessment Questionnaire score, and number of hospitalizations were associated with arterial cardiovascular events.

Conclusion

In this cohort of Puerto Ricans with rheumatoid arthritis, traditional and nontraditional factors, particularly extra-articular manifestations and functional disability, were associated with arterial vascular events. Awareness of these associations may help to implement clinical strategies in this group of rheumatoid arthritis patients at risk of arterial vascular events.

Health Assessment Questionnaire at One Year Predicts All-Cause Mortality in Patients With Early Rheumatoid Arthritis

OBJECTIVE

Higher self-reported disability (high Health Assessment Questionnaire [HAQ] score) has been associated with hospitalizations and mortality in established rheumatoid arthritis (RA), but associations in early RA are unknown.

METHODS

Patients with early RA (symptom duration <1 year) enrolled in the Canadian Early Arthritis Cohort who initiated disease-modifying antirheumatic drugs and had completed HAQ data at baseline and 1 year were included in the study. Discrete-time proportional hazards models were used to estimate crude and multi-adjusted associations of baseline HAQ and HAQ at 1 year with all-cause mortality in each year of follow-up.

RESULTS

A total of 1,724 patients with early RA were included. The mean age was 55 years, and 72% were women. Over 10 years, 62 deaths (3.6%) were recorded. Deceased patients had higher HAQ scores at baseline (mean ± SD 1.2 ± 0.7) and at 1 year (0.9 ± 0.7) than living patients (1.0 ± 0.7 and 0.5 ± 0.6, respectively; P < 0.001). Disease Activity Score in 28 joints (DAS28) was higher in deceased versus living patients at baseline (mean ± SD 5.4 ± 1.3 versus 4.9 ± 1.4) and at 1 year (mean ± SD 3.6 ± 1.4 versus 2.8 ± 1.4) (P < 0.001). Older age, male sex, lower education level, smoking, more comorbidities, higher baseline DAS28, and glucocorticoid use were associated with mortality. Contrary to HAQ score at baseline, the association between all-cause mortality and HAQ score at 1 year remained significant even after adjustment for confounders. For baseline HAQ score, the unadjusted hazard ratio (HR) was 1.46 (95% confidence interval [95% CI] 1.02-2.09), and the adjusted HR was 1.25 (95% CI 0.81-1.94). For HAQ score at 1 year, the unadjusted HR was 2.58 (95% CI 1.78-3.72), and the adjusted HR was 1.75 (95% CI 1.10-2.77).

CONCLUSION

Our findings indicate that higher HAQ score and DAS28 at 1 year are significantly associated with all-cause mortality in a large early RA cohort.

The role of inflammation and genetics in periodontal disease

Periodontitis is a complex disease: (a) various causative factors play a role simultaneously and interact with each other; and (b) the disease is episodic in nature, and bursts of disease activity can be recognized, ie, the disease develops and cycles in a nonlinear fashion. We recognize that various causative factors determine the immune blueprint and, consequently, the immune fitness of a subject. Normally, the host lives in a state of homeostasis or symbiosis with the oral microbiome; however, disturbances in homeostatic balance can occur, because of an aberrant host response (inherited and/or acquired during life). This imbalance results from hyper- or hyporesponsiveness and/or lack of sufficient resolution of inflammation, which in turn is responsible for much of the disease destruction seen in periodontitis. The control of this destruction by anti-inflammatory processes and proresolution processes limits the destruction to the tissues surrounding the teeth. The local inflammatory processes can also become systemic, which in turn affect organs such as the heart. Gingival inflammation also elicits changes in the ecology of the subgingival environment providing optimal conditions for the outgrowth of gram-negative, anaerobic species, which become pathobionts and can propagate periodontal inflammation and can further negatively impact immune fitness. The factors that determine immune fitness are often the same factors that determine the response to the resident biofilm, and are clustered as follows: (a) genetic and epigenetic factors; (b) lifestyle factors, such as smoking, diet, and psychosocial conditions; (c) comorbidities, such as diabetes; and (d) local and dental factors, as well as randomly determined factors (stochasticity). Of critical importance are the pathobionts in a dysbiotic biofilm that drive the viscious cycle. Focusing on genetic factors, currently variants in at least 65 genes have been suggested as being associated with periodontitis based on genome-wide association studies and candidate gene case control studies. These studies have found pleiotropy between periodontitis and cardiovascular diseases. Most of these studies point to potential pathways in the pathogenesis of periodontal disease. Also, most contribute to a small portion of the total risk profile of periodontitis, often limited to specific racial and ethnic groups. To date, 4 genetic loci are shared between atherosclerotic cardiovascular diseases and periodontitis, ie, CDKN2B-AS1(ANRIL), a conserved noncoding element within CAMTA1 upstream of VAMP3, PLG, and a haplotype block at the VAMP8 locus. The shared genes suggest that periodontitis is not causally related to atherosclerotic diseases, but rather both conditions are sequelae of similar (the same?) aberrant inflammatory pathways. In addition to variations in genomic sequences, epigenetic modifications of DNA can affect the genetic blueprint of the host responses. This emerging field will yield new valuable information about susceptibility to periodontitis and subsequent persisting inflammatory reactions in periodontitis. Further studies are required to verify and expand our knowledge base before final cause and effect conclusions about the role of inflammation and genetic factors in periodontitis can be made.

Extent of atherosclerosis after 11-year prospective follow-up in patients with early rheumatoid arthritis was affected by disease severity at diagnosis

Objective: Cardiovascular disease (CVD) is increased among patients with rheumatoid arthritis (RA). The underlying cause is not clear. In this prospective study, patients with early RA were investigated for associations between subclinical atherosclerosis and CVD risk factors as well as inflammation. Method: At diagnosis, RA patients were recruited into a prospective study. A subgroup was included (n = 55) for ultrasound measurements of intima-media thickness (IMT) at inclusion (T0), and after 5 years (T5) and 11 years (T11). Thirty-one age and gender-matched controls were also included for comparison. Results: IMT increased significantly between T0 and T11 among patients and controls (p < 0.0001). No statistically significant differences in IMT between patients and controls were detected at T11, T5, or T0 (p > 0.05 for all). In simple regression models, IMT at T11 was significantly associated with age (p < 0.0001), as well as systolic blood pressure at T0 (p < 0.01) and T11 (p < 0.01) among RA patients. Furthermore, the composite Systematic COronary Risk Evaluation (SCORE) measurements (p < 0.0001) and Reynolds risk score (p < 0.01) and the radiographic Larsen score (p < 0.05) at T0 were all significantly associated with IMT at T11. Results from conditional logistic regression analysis showed an increased progression rate between T0 and T11 in the RA group compared with controls (p < 0.05). Conclusion: We found increased atherosclerotic development among patients with RA compared with controls 11 years after diagnosis. The atherosclerotic burden was associated with disease severity at baseline.

Effect of methotrexate use on the development of type 2 diabetes in rheumatoid arthritis patients: A systematic review and meta-analysis

BACKGROUND

The high risk of cardiovascular disease is well recognized in rheumatoid arthritis. Type 2 diabetes also attributes to this increase in risk. Rheumatoid arthritis is a chronic inflammatory condition, which aggravates insulin resistance, placing the patients at a higher risk of type 2 diabetes and subsequent cardiovascular outcomes. Methotrexate treatment, as a gold standard anti-inflammatory drug in the treatment of rheumatoid arthritis has shown beneficial effects on cardiovascular health. However, its impact on type 2 diabetes is still unknown.

OBJECTIVE

To assess the strength of the association between exposure to methotrexate and the rate of development of type 2 diabetes in rheumatoid arthritis patients.

METHODS

All rheumatoid arthritis studies reporting the use of methotrexate as an exposure and type 2 diabetes as an outcome were searched until March 2020 using MEDLINE, Cochrane and Scopus databases. Studies were included if the diagnosis of rheumatoid arthritis was made according to current guidelines or by a rheumatologist, and if there was information about methotrexate exposure and the type 2 diabetes outcome. The author and an independent assessor evaluated the articles for eligibility. Meta-analyses combined relative risk estimates from each study where raw counts were available.

RESULTS

Sixteen studies reporting sufficient data for inclusion in the meta-analyses were identified. Methotrexate showed a promising effect on the risk of type 2 diabetes as this risk decreased in rheumatoid arthritis patients using methotrexate (Relative risk 0.48, 95% CI 0.16, 1.43).

CONCLUSION

Rheumatoid arthritis patients on methotrexate treatment had a lower risk of developing type 2 diabetes compared to rheumatoid arthritis patients not exposed to methotrexate. This finding highlights the need for future, randomized control trials to confirm the beneficial effect of methotrexate on type 2 diabetes in the rheumatoid arthritis population.

Similar risk of cardiovascular events in idiopathic inflammatory myopathy and rheumatoid arthritis in the first 5 years after diagnosis

OBJECTIVES

To estimate the incidence of cardiovascular (CV) events in idiopathic inflammatory myopathy (IIM) compared to patients with rheumatoid arthritis (RA) and the general population. To explore the contribution of traditional CV risk factors to any difference observed.

METHODS

A retrospective matched population-based cohort study was conducted using UK Clinical Practice Research Datalink (CPRD) from 1987 to 2013. The incidence of CV events was calculated for each cohort over time and compared using Cox proportional hazards models. Multivariable analyses were used to adjust for traditional CV risk factors.

RESULTS

A total of 603 patients with IIM 4047 RA and 4061 healthy controls were included. The rate of CV events in IIM was significantly greater than healthy controls [hazard ratio (HR) 1.47 (95% confidence interval (CI) 1.18-1.83)] and remained significant after adjustment for CV risk factors [HR 1.38 (95% CI 1.11-1.72)]. Risk was similar between IIM and RA [HR 1.01 (95% CI 0.78-1.31)]. The rate of myocardial infarction [HR 1.61 (95% CI 1.27-2.04)] but not stroke [HR 0.92 (95% CI 0.59-1.44)] was significantly greater in IIM compared to healthy controls. After the first 5 years, the rate of CV events for RA remained significantly greater compared to the control group, but appeared to return to that of the healthy controls in the IIM group.

CONCLUSION

IIM is associated with an increased risk of CV events in the first 5 years after diagnosis similar to that of RA. Beyond 5 years, the risk appears to return to that of the general population in IIM but not RA. Key Points • The excess risk of cardiovascular events in IIM is similar to that found in RA. • The excess risk of cardiovascular events is greatest in the first 5 years after diagnosis.

Pharmacological management of cardiovascular risk in chronic inflammatory rheumatic diseases

INTRODUCTION

Cardiovascular comorbidity is a major burden in patients with chronic inflammatory rheumatic diseases and a significant determinant of their outcome. In addition to optimal management of the underlying inflammatory condition according to current guidelines, individual cardiovascular risk factors, particularly dyslipidaemia, hypertension, and impaired glucose tolerance should be assessed regularly and guide risk stratification and requirement for treatment.

AREAS DISCUSSED

We critically reviewed manuscripts and guidelines on the pharmacological management of dyslipidaemia, hypertension, and diabetes in patients with chronic inflammatory rheumatic diseases (PubMed, MEDLINE, EMBASE, Scopus, Web of Science and Google Scholar, up to 1 March 2020). Lifestyle changes are of paramount importance for the management of these risk factors. In the current narrative review, we discuss pharmacological therapies available and emerging therapies aiming to help patients achieve recommended targets, depending on their individual risk.

EXPERT OPINION

CVD risk is increased in people with chronic inflammatory rheumatic diseases. Cardiovascular risk factor management is an essential part of their care. Although relevant guidance exists, there are still major gaps in knowledge and risk factor management implementation in these patient groups. Some practical guidance based on our interpretation of existing data and experience in the field is provided in this review.

Screening of Hyperlipidemia Among Patients With Rheumatoid Arthritis in the United States

OBJECTIVE

To determine the proportion of primary lipid screening among patients with rheumatoid arthritis (RA) and compare it with those among patients with diabetes mellitus (DM) and patients with neither RA nor DM, and to assess whether primary lipid screening varied according to the health care provider (rheumatologist versus non-rheumatologist).

METHODS

We analyzed claims data from US private and public health plans from 2006-2010. Eligibility requirements included continuous medical and pharmacy coverage for ≥12 months (baseline period) and >2 physician diagnoses and relevant medications to define RA, DM, RA and DM, or neither condition. Among the 330,695 eligible participants, we calculated the proportion with a lipid profile ordered during the 2 years following baseline. Time-varying Cox proportional hazard models were used to determine the probability of hyperlipidemia screening in participants with RA according to provider specialty.

RESULTS

More than half of the patients were ages 41-71 years. Among patients with RA (n = 12,182), DM (n = 62,834), RA and DM (n = 1,082), and those who did not have either condition (n = 167,811), the proportion screened for hyperlipidemia was 37%, 60%, 55%, and 41%, respectively. Patients with RA who visited a rheumatologist and a non-rheumatology clinician during follow-up had a 55% (95% confidence interval 1.36-1.78) higher screening probability than those who only visited a rheumatologist.

CONCLUSION

Primary lipid screening was suboptimal among patients with RA. It was also lower for patients with DM and minimally different from the general population. Screening was higher for RA patients who received care from both a rheumatologist and a non-rheumatologist (e.g., primary care physician).

Comparative Risk of Diabetes Mellitus in Patients With Rheumatoid Arthritis Treated With Biologic or Targeted Synthetic Disease-Modifying Drugs: A Cohort Study

Objective

The objective of this study is to compare the risk of incident diabetes mellitus (DM) in patients with rheumatoid arthritis (RA) treated with biologic or targeted synthetic disease‐modifying antirheumatic drugs.

Methods

A new‐user observational cohort study was conducted using data from a US commercial (Truven MarketScan, 2005‐2016) claims database and a public insurance (Medicare, 2010‐2014) claims database. Patients with RA who did not have DM were selected into one of eight exposure groups (abatacept, infliximab, adalimumab, golimumab, certolizumab, etanercept, tocilizumab, or tofacitinib) and observed for the outcome of incident DM, defined as a combination of a diagnosis code and initiation of a hypoglycemic treatment. A stabilized inverse probability–weighted Cox proportional hazards model was used to account for 56 confounding variables and estimate hazard ratios (HRs) and 95% confidence intervals (CIs). All analyses were conducted separately in two databases, and estimates were combined using inverse variance meta‐analysis.

Results

Among a total of 50 505 patients with RA from Truven and 17 251 patients with RA from Medicare, incidence rates (95% CI) for DM were 6.8 (6.1‐7.6) and 6.6 (5.4‐7.9) per 1000 person‐years, respectively. After confounding adjustment, the pooled HRs (95% CI) indicated a significantly higher risk of DM among adalimumab (2.00 [1.11‐3.03]) and infliximab initiators (2.34 [1.38‐3.98]) compared with abatacept initiators. The pooled HR (95% CI) for the etanercept versus abatacept comparison was elevated but not statistically significant (1.65 [0.91‐2.98]). The effect estimates for certolizumab, golimumab, tocilizumab, and tofacitinib, compared with abatacept, were highly imprecise because of a limited sample size.

Conclusion

Initiation of abatacept was associated with a lower risk of incident DM in patients with RA compared with infliximab or adalimumab.

Cardiovascular MRI evidence of reduced systolic function and reduced LV mass in rheumatoid arthritis: impact of disease phenotype

The accelerated risk of cardiovascular disease (CVD) in Rheumatoid Arthritis (RA) requires further study of the underlying pathophysiology and determination of the at-risk RA phenotype. Our objectives were to describe the cardiac structure and function and arterial stiffness, and association with disease phenotype in patients with established) RA, in comparison to healthy controls, as measured by cardiovascular magnetic resonance imaging (CMR). 76 patients with established RA and no history of CVD/diabetes mellitus were assessed for RA and cardiovascular profile and underwent a non-contrast 3T-CMR, and compared to 26 healthy controls. A univariable analysis and multivariable linear regression model determined associations between baseline variables and CMR-measures. Ten-year cardiovascular risk scores were increased in RA compared with controls. Adjusting for age, sex and traditional cardiovascular risk factors, patients with RA had reduced left ventricular ejection fraction (mean difference - 2.86% (- 5.17, - 0.55) p = 0.016), reduced absolute values of mid systolic strain rate (p < 0.001) and lower late/active diastolic strain rate (p < 0.001) compared to controls. There was evidence of reduced LV mass index (LVMI) (- 4.56 g/m2 (- 8.92, - 0.20), p = 0.041). CMR-measures predominantly associated with traditional cardiovascular risk factors; male sex and systolic blood pressure independently with increasing LVMI. Patients with established RA and no history of CVD have evidence of reduced LV systolic function and LVMI after adjustment for traditional cardiovascular risk factors; the latter suggesting cardiac pathology other than atherosclerosis in RA. Traditional cardiovascular risk factors, rather than RA disease phenotype, appear to be key determinants of subclinical CVD in RA potentially warranting more effective cardiovascular risk reduction programs.

The epidemiology of established rheumatoid arthritis

No published epidemiological study has specifically focused on the prevalence of established rheumatoid arthritis (RA), as epidemiologists do not study established RA separated from RA as a whole; especially no incidence studies can be found, as incidence refers to new cases (early RA). Such a study, if it existed, would find a prevalence much larger than that of recent-onset RA, and should be planned based on clear definitions that currently do not exist in epidemiology. As a result, any study addressing RA as a whole, leaving aside early arthritis, would be actually studying established RA. This work reviews the epidemiology of RA, in contraposition of early RA, and tried to highlight epidemiological characteristics of established RA in published studies as well as methodological issues, including differences between recent-onset and established RA regarding the prevalence of comorbidities and other characteristics, and differences across countries. The global epidemiology of established RA teaches us that long-term outcomes could largely depend on health care models and are modifiable.
