The heart and cardiovascular manifestations in rheumatoid arthritis

Management of Rheumatoid Arthritis in Primary Care: A Scoping Review

Rheumatoid arthritis (RA) can lead to severe joint impairment and chronic disability. Primary care (PC), provided by general practitioners (GPs), is the first level of contact for the population with the healthcare system. The aim of this scoping review was to analyze the approach to RA in the PC setting. PubMed, Scopus, and Web of Science were searched using the MESH terms "rheumatoid arthritis" and "primary care" from 2013 to 2023. The search strategy followed the PRISMA-ScR guidelines. The 61 articles selected were analyzed qualitatively in a table and discussed in two sections, namely criticisms and strategies for the management of RA in PC. The main critical issues in the management of RA in PC are the following: difficulty and delay in diagnosis, in accessing rheumatological care, and in using DMARDs by GPs; ineffective communication between GPs and specialists; poor patient education; lack of cardiovascular prevention; and increase in healthcare costs. To overcome these criticisms, several management strategies have been identified, namely early diagnosis of RA, quick access to rheumatology care, effective communication between GPs and specialists, active patient involvement, screening for risk factors and comorbidities, clinical audit, interdisciplinary patient management, digital health, and cost analysis. PC appears to be the ideal healthcare setting to reduce the morbidity and mortality of chronic disease, including RA, if a widespread change in GPs' approach to the disease and patients is mandatory.

Novel Therapeutic Insights Into the Treatment of Pericarditis: Targeting the Innate Immune System

ABSTRACT

Acute pericarditis is characterized by pericardial inflammation that can be treated with anti-inflammatory drugs. A considerable percentage of patients develops recurrent pericarditis with several relapses. In developed countries, the idiopathic form is the most frequent and has a high risk of recurrences. Two pathophysiological mechanisms have been described for idiopathic recurrent pericarditis: autoimmune and autoinflammatory. The autoimmune mechanism is more frequently encountered in patients with rheumatologic disorders, especially systemic lupus erythematosus. The innate immune system plays a central role in the pathophysiology of pericarditis, especially in the autoinflammatory phenotype. Current evidence highlights the central role played by interleukin 1 and NLRP3 (NACHT, leucine-rich repeat, and pyrin domain-containing protein 3) in idiopathic recurrent pericarditis. Accordingly, interleukin 1 blockers have been approved for the treatment of this condition. Neutrophils are likely to be important in such setting; however, their role has only been partially investigated. In the present review, we have collected the current knowledge on the role of innate immune system in pericarditis pathophysiology and how this can be used to provide targeted treatments for patients with recurrent pericarditis.

Long-Term Outcomes After Transcatheter Aortic Valve Implantation in Patients With Chronic Inflammatory Disease

BACKGROUND

Chronic inflammatory disease (CID) accelerates atherosclerosis and the development of aortic stenosis. Data on long-term outcomes after transcatheter aortic valve implantation (TAVI) in those patients are missing. The aim of this study was to investigate the clinical long-term outcomes of patients with and without autoimmune-related CID undergoing TAVI for the treatment of severe aortic stenosis.

METHODS AND RESULTS

From a prospective registry, consecutive patients with TAVI were included. Baseline clinic and imaging data (echocardiographic and computed tomography) were analyzed. Long-term (up to 5 years) clinical and echocardiographic outcomes were studied. Of 1000 consecutive patients (mean age 81±6 years, 46% female), 107 (11%) had CID; the most frequent entities included polymyalgia rheumatica (31%) and rheumatoid arthritis (28%). Patients with CID were predominantly female (60% versus 44%, P=0.002) and more often had pulmonary disorders (21% versus 13%, P=0.046) and atrial fibrillation (32% versus 20%, P=0.003). The presence of CID was associated with a higher rate of postinterventional infection (5% versus 1%, P=0.007) and further emerged as a risk factor for rehospitalization for bleeding or infection (hazard ratio, 1.93 and 1.62, respectively). Premature valve degeneration, endocarditis, and all-cause mortality were not increased among patients with CID.

CONCLUSIONS

This real-world analysis found that patients with CID undergoing TAVI were associated with a higher risk of postinterventional infectious complications and rehospitalization due to infection. However, valve durability and survival seem not to differ between patients with TAVI with versus without CID.

Cardiovascular Manifestations in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a systemic inflammatory disorder that characteristically affects the joints. RA has extra-articular manifestations that can impact multiple organ systems including the heart, lungs, eyes, skin, and brain. Cardiovascular involvement is a leading cause of mortality in RA. Cardiovascular manifestations of RA include accelerated atherosclerosis, heart failure, pericarditis, myocarditis, endocarditis, rheumatoid nodules, and amyloidosis. Inflammation is an important mediator of endothelial dysfunction and is a key driver of cardiovascular risk and complications in patients with RA. Prompt identification of cardiac pathologies in patients with RA is essential for appropriate management and treatment. Choosing the most appropriate treatment regimen is based on individual patient factors. In this article, we provide a comprehensive review of the epidemiology, pathophysiology, clinical manifestations, diagnosis, and medical management of cardiovascular manifestations of RA. We also discuss the relationship between anti-rheumatic medications, specifically non-steroidal anti-inflammatory drugs, corticosteroids, methotrexate, statins, tumor necrosis factor inhibitors, interleukin-6 inhibitors, Janus kinase inhibitors, and cardiovascular disease.

The inflammatory spectrum of cardiomyopathies

Infiltration of the myocardium with various cell types, cytokines and chemokines plays a crucial role in the pathogenesis of cardiomyopathies including inflammatory cardiomyopathies and myocarditis. A more comprehensive understanding of the precise immune mechanisms involved in acute and chronic myocarditis is essential to develop novel therapeutic approaches. This review offers a comprehensive overview of the current knowledge of the immune landscape in cardiomyopathies based on etiology. It identifies gaps in our knowledge about cardiac inflammation and emphasizes the need for new translational approaches to improve our understanding thus enabling development of novel early detection methods and more effective treatments.

Immune-mediated inflammatory diseases and the risk of valvular heart disease: a Mendelian randomization study

BACKGROUND

Observational studies have suggested that immune-mediated inflammatory diseases (IMIDs) are associated with a higher risk of valvular heart disease (VHD). But the potential causal association is not clear. Therefore, we used Mendelian randomization (MR) analysis to assess the causal association of IMIDs with VHD risk.

METHODS

A two-sample MR analysis was performed to confirm the causal association of several common IMIDs (systemic lupus erythematosus, SLE; rheumatoid arthritis, RA; multiple sclerosis, MS; ankylosing spondylitis, AS; psoriasis, PSO; inflammatory bowel disease, IBD) with the risk of VHD. The exposure data is derived from published genome-wide association studies (GWASs) and outcome data come from the FinnGen database (47,003 cases and 182,971 controls). Inverse-variance weighted (IVW), MR-Egger, and weighted median methods were performed to assess the causal association. The study design applied univariable MR and multivariable MR.

RESULTS

The MR analysis indicated that several genetically predicted IMIDs increased the risk of VHD, including SLE (odds ratio (OR) = 1.014; 95% confidence interval (CI) =  < 1.001,1.028 > ; p = 0.036), RA (OR = 1.017; 95% CI =  < 1.002,1.031 > ; p = 0.025), and IBD (OR = 1.018; 95% CI =  < 1.002,1.033 > ; p = 0.023). Multivariable MR indicated that the adverse effect of these IMIDs on VHD was dampened to varying degrees after adjusting for smoking, obesity, coronary artery disease, and hypertension.

CONCLUSION

Our findings support the first genetic evidence of the causality of genetically predicted IMIDs with the risk of developing into VHD. Our results deliver a viewpoint that further active intervention needs to be explored to mitigate VHD risk in patients with SLE, RA, and IBD. Key Points • Genetically predicted systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and inflammatory bowel disease (IBD) are causally associated with valvular heart disease (VHD). • To reduce the risk of VHD in patients with SLE, RA, and IBD, active interventions should be further explored.

The usual Interstitial pneumonia pattern in autoimmune rheumatic diseases

Usual Interstitial Pneumonia (UIP) is characterized by progression of lung parenchyma that may be observed in various autoimmune rheumatic diseases (ARDs), including rheumatoid arthritis and connective tissue diseases. From a diagnostic point of view, a UIP pattern related to ARDs may display imaging and pathological features able to distinguish it from that related to IPF, such as the "straight-edge" sign at HRCT and lymphoplasmacytic infiltrates at histologic specimens. Multidisciplinary approach (MDD), involving at least pulmonologist, rheumatologist and radiologist, is fundamental in the differential diagnosis process, but MDD is also required in the evaluation of severity, progression and response to treatment, that is based on the combination of changes in symptoms, pulmonary function trends, and, in selected patients, serial CT evaluation. Differently from IPF, in patients with ARDs both functional evaluation and patient-reported outcomes may be affected by systemic involvement and comorbidities, including musculoskeletal manifestations of disease. Finally, in regards to pharmacological treatment, immunosuppressants have been considered the cornerstone of therapy, despite the lack of solid evidence in most cases; recently, antifibrotic drugs were also proposed for the treatment of progressive fibrosing ILDs other than IPF. In ARD-ILD, the therapeutic choice should balance the need for the control of systemic and lung involvements with the risk of adverse events from multi-morbidities and -therapies. Purpose of this review is to summarize the definition, the radiological and morphological features of the UIP pattern in ARDs, together with risk factors, diagnostic criteria, prognostic evaluation, monitoring and management approaches of the UIP-ARDs.

Chronic constrictive pericarditis: a rare cardiac involvement in primary Sjögren's syndrome

BACKGROUND

Constrictive pericarditis represents a chronic condition and systemic inflammatory diseases are a known, yet uncommon, cause. Pericardial involvement is seldom reported in primary Sjögren's syndrome, usually occurring in association with pericardial effusion or pericarditis. We report a case of constrictive pericarditis with an insidious course and unusual evolution associated with primary Sjögren's syndrome. Due to the challenging nature of the diagnosis, clinical suspicion and multimodality imaging are essential for early identification and prompt initiation of treatment. Long-term outcomes remain uncertain. To the best of our knowledge, no other cases linking this autoimmune disease to constrictive pericarditis have been reported.

CASE PRESENTATION

We present the case of a 48-year-old male patient with moderate alcohol habits and a history of two prior hospitalizations. On the first, the patient was diagnosed with primary Sjögren's syndrome after presenting with pleural effusion and ascites, and empirical corticosteroid regiment was initiated. On the second, two-years later, he was readmitted with complaints of dyspnea and abdominal distension. Thoracic computed tomography revealed a localized pericardial thickening and a thin pericardial effusion, both of which were attributed to his rheumatic disease. A liver biopsy showed hepatic peliosis, which was considered to be a consequence of glucocorticoid therapy. Diuretic therapy was adjusted to symptom-relief, and a tapering corticosteroid regimen was adopted. Four years after the initial diagnosis, the patient was admitted again with recurrent dyspnea, orthopnea and ascites. At this time, constrictive pericarditis was diagnosed and a partial pericardiectomy was performed. Although not completely asymptomatic, the patient reported clinical improvement since the surgery, but still with a need for baseline diuretic therapy.

CONCLUSION

Albeit uncommon, connective tissue disorders, such as primary Sjögren's syndrome, should be considered as a potential cause of constrictive pericarditis, especially in young patients with no other classical risk factors for constriction. In this case, after excluding possible infectious, neoplastic and autoimmune conditions, a primary Sjögren´s syndrome in association with constrictive pericarditis was assumed. This case presents an interesting and challenging clinical scenario, highlighting the importance of clinical awareness and the use of multimodal cardiac imaging for early recognition and treatment.

The Evolving Etiologic and Epidemiologic Portrait of Pericardial Disease

Pericardial disease includes a variety of conditions, including inflammatory pericarditis, pericardial effusions, constrictive pericarditis, pericardial cysts, and primary and secondary pericardial neoplasms. The true incidence of this varied condition is not well established, and the causes vary greatly across the world. This review aims to describe the changing pattern of epidemiology of pericardial disease and to provide an overview of causative etiologies. Idiopathic pericarditis (assumed most often to be viral) remains the most common etiology for pericardial disease globally, with tuberculous pericarditis being most common in developing countries. Other important etiologies include fungal, autoimmune, autoinflammatory, neoplastic (both benign and malignant), immunotherapy-related, radiation therapy-induced, metabolic, postcardiac injury, postoperative, and postprocedural causes. Improved understanding of the immune pathophysiological pathways has led to identification and reclassification of some idiopathic pericarditis cases into autoinflammatory etiologies, including immunoglobulin G (IgG)4-related pericarditis, tumour necrosis factor receptor-associated periodic syndrome (TRAPS), and familial Mediterranean fever in the current era. Contemporary advances in percutaneous cardiac interventions and the recent COVID-19 pandemic have also resulted in changes in the epidemiology of pericardial diseases. Further research is needed to improve our understanding of the etiologies of pericarditis, using the assistance of contemporary advanced imaging techniques and laboratory testing. Careful consideration of the range of potential causes and local epidemiologic patterns of causality are important for the optimization of diagnostic and therapeutic approaches.

Responsiveness to endurance training can be partly explained by the number of favorable single nucleotide polymorphisms an individual possesses

Cardiorespiratory fitness is a key component of health-related fitness. It is a necessary focus of improvement, especially for those that have poor fitness and are classed as untrained. However, much research has shown individuals respond differentially to identical training programs, suggesting the involvement of a genetic component in individual exercise responses. Previous research has focused predominantly on a relatively low number of candidate genes and their overall influence on exercise responsiveness. However, examination of gene-specific alleles may provide a greater level of understanding. Accordingly, this study aimed to investigate the associations between cardiorespiratory fitness and an individual's genotype following a field-based endurance program within a previously untrained population. Participants (age: 29 ± 7 years, height: 175 ± 9 cm, mass: 79 ± 21 kg, body mass index: 26 ± 7 kg/m2) were randomly assigned to either a training (n = 21) or control group (n = 24). The training group completed a periodized running program for 8-weeks (duration: 20-30-minutes per session, intensity: 6-7 Borg Category-Ratio-10 scale rating, frequency: 3 sessions per week). Both groups completed a Cooper 12-minute run test to estimate cardiorespiratory fitness at baseline, mid-study, and post-study. One thousand single nucleotide polymorphisms (SNPs) were assessed via saliva sample collections. Cooper run distance showed a significant improvement (0.23 ± 0.17 km [11.51 ± 9.09%], p < 0.001, ES = 0.48 [95%CI: 0.16-0.32]), following the 8-week program, whilst controls displayed no significant changes (0.03 ± 0.15 km [1.55 ± 6.98%], p = 0.346, ES = 0.08, [95%CI: -0.35-0.95]). A significant portion of the inter-individual variation in Cooper scores could be explained by the number of positive alleles a participant possessed (r = 0.92, R2 = 0.85, p < 0.001). These findings demonstrate the relative influence of key allele variants on an individual's responsiveness to endurance training.

Why and How Should We Assess the Cardiovascular Risk in Patients with Juvenile Idiopathic Arthritis? A Single-Centre Experience with Carotid Intima-Media Measurements

Background: Children diagnosed with juvenile idiopathic arthritis (JIA) are thought to be more likely to develop cardiovascular disease in adulthood. The factors modulating the cardiovascular risk, involving exposure to secondhand smoking, sedentary lifestyle and abnormal body mass index, might have had a stronger impact during the COVID-19 pandemic. The lack of reliable prognostic markers for a higher probability of cardiovascular events might be solved by carotid intima-media thickness (cIMT) measurement. The paramount goal of the study was to assess its usefulness in JIA patients. Materials and Methods: The results of cIMT measured by a single physician in 45 children diagnosed with JIA were compared to 37 age- and sex-matched healthy counterparts. The analysis also involved anthropometric parameters, laboratory tests, and a survey regarding lifestyle-related factors. Results: Four JIA patients appeared to have cIMT above the 94th percentile. A positive correlation between erythrocytes sedimentation rate (ESR) and right carotid artery percentiles was found. Passive smoking increased the cardiovascular risk regardless of JIA. Doubling the daily screen time during the pandemic led to a significant reduction in children’s physical activity. However, the number of enrolled subjects was not enough to make significant recommendations. Conclusions: cIMT measurements remain an interesting perspective for future cardiovascular screening of children with JIA. It has yet to be determined whether it should be considered in all JIA patients on a reliable basis.

Cardiac damage in autoimmune diseases: Target organ involvement that cannot be ignored

Autoimmune diseases are diseases that cause damage to the body's own tissues as a result of immune dysfunction, often involving multiple organs and systems. The heart is one of the common target organs of autoimmune diseases. The whole structure of the heart can be affected, causing microcirculatory disorders, arrhythmias, pericardial damage, myocarditis, myocardial fibrosis, and impaired valvular function. However, early clinical manifestations of autoimmune heart damage are often overlooked because they are insidious or have no typical features. The damage is often severe and irreversible when symptoms are apparent, even life-threatening. Therefore, early detection and treatment of heart damage in autoimmune diseases is particularly important. Herein, we review the clinical features and mechanisms of cardiac damage in common rheumatic diseases.

Autoimmune Pericarditis: Multimodality Imaging

PURPOSE OF THE REVIEW

The purpose of this review is to understand the underlying mechanism that leads to pericarditis in systemic autoimmune and autoinflammatory diseases. The underlying mechanism plays a vital role in the appropriate management of patients. In addition, we will review the current landscape of available cardiac imaging modalities with emphasis on pericardial conditions as well as proposed treatment and management tailored toward pericardial autoimmune and autoinflammatory processes.

RECENT FINDINGS

Approximately 22% of all cases of pericarditis with a known etiology are caused by systemic autoimmune diseases such as systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, and vasculitis. In recent years, there have been advancements of imaging modalities including cardiac MRI, cardiac CT scan, and PET scan and their respective nuances in regard to contrast use, technique, and views which clinicians may utilize to better understand the extent of a patient's pericardial pathology and the trajectory of his or her disease process. In this review, we will discuss systemic autoimmune and autoinflammatory diseases that involve the pericardium. We will also review different imaging modalities that are currently used to further characterize such conditions. Having a deeper understanding of such techniques will improve patient outcomes by helping clinicians tailor treatment plans according to the unique underlying condition.

All that Glitters is not Cholecystitis. A Rare Presentation of Acute Pericarditis Mimicking Cholecystitis and Review of the Literature

Acute pericarditis is the most common inflammatory disorder of the pericardium, responsible for approximately 5% of visits to the emergency departments, concerning chest pain without myocardial infarction. We report a case of a 41-year-old man who presented to our hospital, complaining about retrosternal and epigastrium pain. The transthoracic echocardiogram showed pericardial effusion while the electrocardiogram and laboratory findings revealed acute pericarditis. An abdominal ultrasound revealed gallbladder edema. The pericardial effusion was treated with pericardial catheter insertion, diuretics, and nonsteroidal anti-inflammatory drugs. This case shows that acute pericarditis can be clinically presented with many ways, one of them being gallbladder edema. Furthermore, in this case-based review we present all cases of simultaneous appearance of pericarditis and acalculous cholecystitis or gallbladder edema.

Autoimmune connective tissue diseases and aortic valve replacement outcomes: a population-based study

Aims

Patients with autoimmune connective tissue diseases (CTDs) have a high burden of valvular heart disease and are often thought of as high surgical risk patients.

Methods and results

Patients undergoing aortic valve replacement (AVR) were identified in the Nationwide Readmissions Database between January 2012 and December 2018. Patients with a history of systemic lupus erythematosus, rheumatoid arthritis, systemic sclerosis, mixed C, Sjögren syndrome, polymyositis, and dermatomyositis were included in the CTD cohort. Patients undergoing coronary artery bypass grafting concomitantly with AVR were excluded. A total of 569 600 hospitalizations were included, of which16 531 (2.9%) had CTD. CTD patients were more likely to be females, with higher rates of heart failure, pulmonary hypertension, and more likely to be insured by Medicare. CTD patients had lower mortality than non-CTD patients [odds ratio (OR) 0.66; 95% confidence interval (CI): 0.59–0.74] and stroke [OR 0.87; 95% (CI): 0.79–0.97]. CTD patients undergoing SAVR had lower mortality [OR 0.69; 95% (CI): 0.60–0.80] and stroke [OR 0.86; 95% (CI): 0.75–0.98). CTD patients undergoing TAVR had lower mortality outcomes [OR 0.67; 95% (CI): 0.56–0.80]; however, they had comparable stroke outcomes [OR 0.97; 95% (CI): 0.83–1.13, P = 0.69].

Conclusions

Outcomes for patients with CTD requiring AVR are not inferior to their non-CTD counterparts. A comprehensive heart team selection of patients undergoing AVR approaches should place CTD history under consideration; however, pre-existing CTD should not be prohibitive of AVR interventions.

Interleukin-1 Antagonists for the Treatment of Recurrent Pericarditis

Although most patients with acute pericarditis will recover, a minority will have recurrent, debilitating episodes. In these patients, refractory symptoms result in high morbidity, and typically require a prolonged duration of anti-inflammatory treatment. Initially, the efficacy of colchicine in both recurrent pericarditis and periodic fever syndromes suggested the central role of the inflammasome in pericarditis. Subsequently, the success of interleukin-1 antagonists in autoinflammatory diseases prompted further investigation in recurrent pericarditis. In current clinical practice, interleukin-1 antagonists include canakinumab, anakinra, and rilonacept. Both anakinra and rilonacept have demonstrated efficacy in randomized trials of patients with recurrent pericarditis. The aim of the current review is to explain the biological rationale for interleukin-1 antagonists in recurrent pericarditis, highlight supporting clinical evidence, and emphasizing future areas of investigation.

MicroRNAs (miRNAs) in Cardiovascular Complications of Rheumatoid Arthritis (RA): What Is New?

Rheumatoid Arthritis (RA) is among the most prevalent and impactful rheumatologic chronic autoimmune diseases (AIDs) worldwide. Within a framework that recognizes both immunological activation and inflammatory pathways, the exact cause of RA remains unclear. It seems however, that RA is initiated by a combination between genetic susceptibility, and environmental triggers, which result in an auto-perpetuating process. The subsequently, systemic inflammation associated with RA is linked with a variety of extra-articular comorbidities, including cardiovascular disease (CVD), resulting in increased mortality and morbidity. Hitherto, vast evidence demonstrated the key role of non-coding RNAs such as microRNAs (miRNAs) in RA, and in RA-CVD related complications. In this descriptive review, we aim to highlight the specific role of miRNAs in autoimmune processes, explicitly on their regulatory roles in the pathogenesis of RA, and its CV consequences, their main role as novel biomarkers, and their possible role as therapeutic targets.

Pericarditis With Cardiac Tamponade Mimicking Yellow Nail Syndrome in a Patient With Rheumatoid Arthritis and a Paucity of Joint Symptoms

Pericarditis is a cardiac disease that commonly manifests with rheumatoid arthritis, and its complications are related to rheumatoid arthritis disease activity. The diagnosis can be complicated in patients with multiple extra-joint complications of rheumatoid arthritis. We report a case of pericarditis in an 82-year-old woman with few joint symptoms who was admitted to the hospital due to worsening edema of the lower legs and dyspnea, which progressed to cardiac tamponade. The patient presented with gradual onset of edema of both lower limbs and bilateral pleural effusion and was initially diagnosed with yellow nail syndrome. Ultimately, the patient was diagnosed with rheumatoid pericarditis due to a rapid increase in pericardial effusion. She was treated with non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine; however, the symptoms were progressive and required pericardiocentesis. After pericardiocentesis, the patient responded well to NSAIDs and colchicine, and systemic edema was relieved. This case highlights the fact that pericarditis associated with rheumatoid arthritis is not necessarily related to the severity of joint symptoms. Moreover, it can be difficult to differentiate pericarditis from multiple other diseases, such as yellow nail syndrome, in patients with rheumatoid arthritis who mainly have extra-articular symptoms.

Role of non-invasive multimodality imaging in autoimmune pericarditis

Systemic autoimmune diseases are an important cause of pericardial involvement and contribute to up to ∼22% cases of pericarditis with a known aetiology. The underlying mechanism for pericardial involvement varies with each systemic disease and leads to a poor understanding of its management. Multimodality imaging establishes the diagnosis and determines the type and extent of pericardial involvement. In this review, we elaborate upon various pericardial syndromes associated with different systemic autoimmune and autoinflammatory diseases and the multitude of imaging modalities that can be used to further characterize autoimmune pericardial involvement. Lastly, these forms of pericarditis have a greater likelihood of recurrence, and clinicians need to understand their unique treatment approaches to improve patient outcomes.

Evolving Chest Pain in a Young Male

A 33-year-old Hispanic male with a history of recent orchiectomy for suspected testicular cancer presented to the emergency department with worsening exertional chest pain and dyspnea in the setting of a 2-month history of diffuse myalgias and symmetric polyarthralgias.

[Redo aortic valve reconstruction as saving surgery in a patient with severe rheumatoid cardiac disease]

The combination of aortic regurgitation, rheumatoid aortitis, and subaortic stenosis is rare in patients with rheumatoid arthritis. Moreover, the surgical treatment of these entities can be challenging and with non-adequate results. We report a case of a patient with severe aortic regurgitation, inaccessible aortic root secondary to rheumatoid aortitis, and severe subaortic stenosis initially treated by aortic valve replacement. We reoperated the patient due to acute prosthetic valve failure by an aortic valve reconstruction using bovine pericardium and Ozaki technique with good outcomes.

Increased Risk of Valvular Heart Disease in Systemic Sclerosis: An Underrecognized Cardiac Complication

OBJECTIVE

Cardiac involvement is a poor prognostic marker in systemic sclerosis (SSc). While diastolic dysfunction, myocardial fibrosis, and arrhythmias are traditionally considered features of primary cardiac involvement in SSc, the incidence of valvular heart disease (VHD) is not well reported. Our objective was to examine the prevalence of VHD at the time of SSc diagnosis and incidence of VHD during follow-up compared to non-SSc subjects.

METHODS

Medical records of patients with suspicion of SSc were reviewed to identify incident cases. SSc subjects were matched 1:2 by age and sex to non-SSc subjects.

RESULTS

The study included 78 incident SSc cases and 156 non-SSc comparators (56 yrs [± 15.7], 91% female). A nearly 4-fold increase in the prevalence of moderate/severe VHD prior to SSc diagnosis compared to non-SSc subjects (6% vs 0%; P = 0.004) was identified. During follow-up, 18 SSc and 12 non-SSc patients developed moderate/severe VHD. The cumulative incidence of VHD at 10 years after SSc incidence/index was 17.9% (95% CI 10.7-29.9) in patients with SSc compared with 2.3% (95% CI 0.7-7.0) in non-SSc subjects (HR 4.23, 95% CI 2.03-8.83). Coronary artery disease was the only significant risk factor for VHD.

CONCLUSION

Patients with SSc have a 4-fold increase in the prevalence of moderate/severe VHD at diagnosis compared to non-SSc patients. They also have a 4-fold increased risk of developing moderate/severe VHD after diagnosis of SSc. Aortic stenosis and mitral regurgitation have a much higher prevalence in patients with SSc, besides secondary tricuspid regurgitation. Underlying mechanisms for this association require further elucidation.

Incidence of congestive heart failure in rheumatoid arthritis: a review of literature and meta-regression analysis

AIMS

Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disorder that not only affects peripheral joints but also increases the risk for cardiovascular disease (CVD) and mortality. Heart failure (HF) appears to be one of the most important contributors to the excess mortality risk among patients with RA. We assessed the incidence of HF in patients with RA compared with age-matched and sex-matched non-RA subjects, after accounting for traditional cardiovascular risk factors and clinical ischemic heart disease.

METHODS AND RESULTS

We performed an aggregate analysis on three studies of RA patients having listed manifestations of HF. We performed a meta-regression analysis to evaluate the incidence of HF in RA patients with increased age and noted for any gender correlation. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using both fixed-effects and random-effects models. In the cumulative analysis of 5, 220, 883 patients, the incidence of HF was noted to be almost two-fold higher in patients with RA compared with a matched control population (OR 1.78, 95% CI 1.22-2.60, P < 0.003), HTN (OR 1.66, 95% CI 1.24-2.23, P < 0.001), and diabetes (OR 1.57, 95% CI 1.36-1.81, P < 0.001). Women had three-fold higher incidence of HF with RA (OR 3.38, 95% CI 2.59-4.40, P < 0.001). On meta-regression, the incidence of HF increased further with older age (coefficient = 0.12, P = 0.0004).

CONCLUSIONS

Our systematic review that included over 5 million subjects confirms the suspected increased incidence of HF in RA patients. Women have the greatest risk for HF. Our analysis advocates the need for updating the current guidelines to incorporate screening and preventive methods for HF in RA patients.

Pericarditis in Systemic Rheumatologic Diseases

PURPOSE OF REVIEW

We review the epidemiology, pathophysiology, and management of pericarditis most commonly complicating autoimmune and autoinflammatory conditions.

RECENT FINDINGS

Typically, pericarditis occurs in the context of a systemic flare of the underlying disease but infrequently, it is the presenting manifestation requiring a high index of suspicion to unravel the indolent cause. Pericardial involvement in rheumatic diseases encompasses a clinical spectrum to include acute, recurrent and incessant pericarditis, constrictive pericarditis, asymptomatic pericardial effusion, and pericardial tamponade. Direct evidence on the pathophysiology of pericarditis in the context of rheumatic diseases is scant. It is theorized that immune perturbations within pericardial tissue result from the underlying central immunopathology of the respective autoimmune or autoinflammatory disease. Pericarditis management depends on acuity, the underlying cause and epidemiological features such as patient's immune status and geographic prevalence of infections such as tuberculosis. Immunosuppressive medications including biologics such as interleukin 1 blockers emerge as possible steroid sparing agents for pericarditis treatment.

Echocardiography in Autoimmune Rheumatic Diseases for Diagnosis and Prognosis of Cardiovascular Complications

Autoimmune rheumatic diseases are systemic diseases frequently affecting the heart and vessels. The main cardiovascular complications are pericarditis, myocarditis, valvular disease, obstructive coronary artery disease and coronary microcirculatory dysfunction, cardiac failure and pulmonary hypertension. Echocardiography, including transthoracic two and three-dimensional echocardiography, Doppler imaging, myocardial deformation and transesophageal echo, is an established and widely available imaging technique for the identification of cardiovascular manifestations that are crucial for prognosis in rheumatic diseases. Echocardiography is also important for monitoring the impact of drug treatment on cardiac function, coronary microcirculatory function, valvular function and pulmonary artery pressures. In this article we summarize established and evolving knowledge on the role of echocardiography for diagnosis and prognosis of cardiovascular abnormalities in rheumatic diseases.

Multiple coronary aneurysms and acute myocardial infarction in a female patient with rhupus: case report and literature review

Coronary artery aneurysms (CAA) are an infrequent cause of coronary artery disease in both systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA), most occurring as a result of acute coronary syndromes (ACS). Until now, no cases of CAA have been described in a patient with rhupus syndrome (RhS). Differentiating whether CAA stem from primary vasculitis, atherosclerosis, or a combination of both continues to pose a significant challenge. We present the first described clinical case of a 43-year-old patient with RhS and multiple CAA identified by the presentation of an acute myocardial infarction. The presence of multiple cardiovascular risk factors and the absence of inflammatory findings, both in PET-CT and arterial biopsy, favored an atherosclerotic versus a vasculitic etiology of the CAA. At the time of the aneurysms diagnosis, the patient showed no signs of SLE activity and only moderate RA activity, which underscores the importance of screening for silent coronary aneurysms in these patients, even in subjects exhibiting little apparent activity from their underlying disease. This case also exemplifies the severe impact of atherosclerotic burdens on such patients, demanding vigilance and aggressiveness in its prevention, early diagnosis, and treatment. We hypothesize that RhS could engender an even greater risk of presenting CAA than either SLE or RA on their own, which therefore warrants more careful follow-up in these patients.

Chronic inflammatory diseases, myocardial function and cardioprotection

The association between chronic inflammatory diseases (CIDs) and increased cardiovascular (CV) risk is well documented and can be a most threatening complication in these patients. However, the pathogenetic mechanisms underlying increased CV risk remain elusive, especially in their cellular and biochemical pathways. Using animal models to understand mechanisms underlying cardiac involvement are limited. Additionally, treatments may influence cardiovascular events through different outcomes. Some drugs used to treat CIDs can negatively affect cardiac function by a direct toxicity, whereas others may protect the myocardium. In the present article, we focus on the cardiac manifestations and risk factors, the pathogenetic mechanisms, and the effect of treatments on myocardial function and cardioprotection for five common worldwide CIDs (rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, psoriasis and inflammatory bowel disease). We also give recommendations in order to evaluate common targets between CID and CV disease (CVD) and to design therapies to alleviate CID-related CVD.

Asymmetric and symmetric dimethylarginine concentration as an indicator of cardiovascular diseases in rheumatoid arthritis patients: a systematic review and meta-analysis of case-control studies

Rheumatoid arthritis (RA) is the most common type of inflammatory arthritis leading to joint damage and physical disability. Cardiovascular diseases (CVDs) are considered a common comorbidity in patients with RA. However, the mechanism underlying its pathogenesis is not definitively explained. Endothelial dysfunction caused by impaired nitric oxide synthesis is an early indicator of cardiovascular disease. Asymmetric and symmetric dimethylarginine (ADMA and SDMA, respectively) the inhibitors of endothelial nitric oxide synthase (NOS) have emerged as novel CVD risk factor determiners. Concerning the unmet need to identify a salutary biomarker for CVD prediction, the purpose of this meta-analysis was to assess the serum/plasma ADMA and SDMA levels in RA patients compared with the healthy controls. A thorough literature search was performed in PubMed, Scopus, Web of Science, and Google Scholar to identify all studies reporting ADMA and/or SDMA levels in RA patients compared with healthy controls. The quality of studies was evaluated using the Newcastle-Ottawa scale (NOS). Pooled standard mean difference (SMD) with 95% confidence interval (CI) was used as the effect size in this study. We also conducted stratified analysis based on assay methods and median age of the participants. Fourteen articles were included. The pooled serum/plasma levels of ADMA were higher in RA patients compared with those of healthy controls (SMD = 1.02, 95% CI = 0.49 to 1.55); However, no statistical differences between RA patients and healthy controls in serum/plasma SDMA levels was seen (SMD = 0.57, 95% CI = -0.21 to 1.36). Subgroup analyses suggested that participants aged > 50 years had higher levels of ADMA rather than controls and the measurement method was a source of heterogeneity for ADMA. According to the results of this meta-analysis, ADMA measurement but not SDMA, can be useful for assessment of endothelial dysfunction as a predictor of CVD risk in RA patients.

Sex and Cardiovascular Involvement in Inflammatory Joint Diseases

The term inflammatory joint disease (IJD) encompasses a group of chronic conditions with predominant joint involvement. They share an increased risk of cardiovascular (CV) complications. However, the implication of the sex in the risk of CV disease in IJD has not been specifically addressed. The aim of this work is to assess the influence of sex on the clinical expression of CV manifestations associated to IJD. With this objective, an update of the current knowledge of the sex influence on CV disease in patients with IJD was conducted. A PubMed database search of the most relevant literature on this topic was performed mainly based on studies published in English over the last 10 years. Although most studies on IJD were not specifically designed to address sex differences regarding CV complications, it seems that men with rheumatoid arthritis (RA) are at higher risk of pericarditis, ischemic heart disease, heart failure (HF) with reduced ejection fraction (EF), and CV mortality than women with RA. In contrast, HF with preserved EF and diastolic dysfunction is more frequent in women with RA. Men with ankylosing spondylitis present more frequently disorders of the conduction system and aortic valvulopathy than women. A limited number of studies addressed CV differences according to sex in psoriatic arthritis. Although there are some differences according to sex in the clinical expression of CV complications in patients with IJD, much research is still needed to better identify the implication of sex in the risk of CV disease in these patients.

Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement in Patients With Rheumatoid Arthritis (from the Nationwide Inpatient Database)

Little is known on the outcomes of surgical aortic valve replacement (SAVR) versus transcatheter aortic valve implantation (TAVI) in patients with rheumatoid arthritis (RA). We queried the Nationwide Inpatient Sample Database (2012 to 2016). We performed a propensity-score-matched analysis based on 25 clinical and hospital variables to compare patients with RA who underwent SAVR versus TAVI. Our primary outcome was in-hospital mortality. Our final analysis included 5,640 hospitalizations with RA who underwent isolated AVR; of whom, 2,465 (43.7%) underwent TAVI. There was an increasing trend in TAVI procedures during the study years (p_trend= 0.001). There was a trend toward reduced in-hospital mortality among TAVI compared with SAVR but did not reach statistical significance (0.8% vs 1.6%, odds ratio = 0.50; 95% confidence interval 0.23 to 1.06, p = 0.097). TAVI was associated with lower rates of postoperative bleeding (28.7% vs 43.9%, p <0.001), blood transfusion (12.3% vs 40.2%, p <0.001), acute kidney injury (9.8% vs 16.0%, p <0.001), cardiac tamponade (0.0% vs 1.6%, p <0.001), and discharges to skilled nursing facility (SNF) (20.1% vs 42.2%, p <0.001). However, TAVI was associated with a higher rate of complete heart block (14.3% vs 6.1%, p <0.001) and pacemaker implantations (14.8% vs 5.7%, p <0.001). There were no differences between both groups in cardiogenic shock, acute stroke, acute myocardial infarction, and vascular complications. In conclusion, real-word data showed no significant difference in in-hospital mortality between TAVI and SAVR in patients with RA. TAVI was associated with lower rates of acute kidney injury and bleeding complications at the expense of higher incidence of pacemaker implantations.

The incidence of extra-articular manifestations in southern Chinese patients with inflammatory joint diseases

AIM

Inflammatory joint diseases (IJDs) are chronic arthritis, but frequently present with co-morbidities of other organs and systems, which is known as extra-articular manifestations (EAMs). It is still unclear which clinical characteristics or bio-markers can predict the development of EAMs. The aim of this study was to estimate the proportion of EAMs in southern Chinese patients with IJDs and to explore the risk factors.

METHODS

This was a retrospective cohort study of a total 1135 IJDs patients, including 788 rheumatoid arthritis (RA) patients, 307 ankylosing spondylitis (AS) patients and 40 psoriatic arthritis (PsA) patients. Demographic data, disease characteristics, laboratory blood tests, medical imaging, and the presence of EAMs were recorded.

RESULTS

We found 459 (40.44%) patients presented with EAMs: 30.84% had cardiovascular involvement, 7.67% had pulmonary involvement, 5.29% had osteoporosis/low bone mineral density, 2.29% had ocular, 0.79% had gastrointestinal and 0.26% had renal involvements. Multivariate logistic regression showed older age (odds ratio [OR] 1.06, P < .001) and higher anti-cyclic citrullinated peptide antibody (anti-CCP) levels (OR 1.003, P = .019) were independent risks of EAMs in RA patients. In the AS group, older age (OR 1.07, P < .001) and higher disease activity (OR 3.24-7.42, both P < .05), were independent risks of EAMs. In the PsA group, longer disease duration (OR 1.01, P = .036) and higher disease activity (OR 1.15, P = .004) were univariate associated factors.

CONCLUSION

These results suggested the high prevalence of EAMs, and it is important to regularly screen for EAMs, as they influence treatment decisions and impact on patients' quality of life.

Identification of Target Genes at Juvenile Idiopathic Arthritis GWAS Loci in Human Neutrophils

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease among children which could cause severe disability. Genomic studies have discovered substantial number of risk loci for JIA, however, the mechanism of how these loci affect JIA development is not fully understood. Neutrophil is an important cell type involved in autoimmune diseases. To better understand the biological function of genetic loci in neutrophils during JIA development, we took an integrated multi-omics approach to identify target genes at JIA risk loci in neutrophils and constructed a protein-protein interaction network via a machine learning approach. We identified genes likely to be JIA risk loci targeted genes in neutrophils which could contribute to JIA development.

Cardiac phenotype in mouse models of systemic autoimmunity

Patients suffering from systemic autoimmune diseases are at significant risk of cardiovascular complications. This can be due to systemically increased levels of inflammation leading to accelerated atherosclerosis, or due to direct damage to the tissues and cells of the heart. Cardiac complications include an increased risk of myocardial infarction, myocarditis and dilated cardiomyopathy, valve disease, endothelial dysfunction, excessive fibrosis, and bona fide autoimmune-mediated tissue damage by autoantibodies or auto-reactive cells. There is, however, still a considerable need to better understand how to diagnose and treat cardiac complications in autoimmune patients. A range of inducible and spontaneous mouse models of systemic autoimmune diseases is available for mechanistic and therapeutic studies. For this Review, we systematically collated information on the cardiac phenotype in the most common inducible, spontaneous and engineered mouse models of systemic lupus erythematosus, rheumatoid arthritis and systemic sclerosis. We also highlight selected lesser-known models of interest to provide researchers with a decision framework to choose the most suitable model for their study of heart involvement in systemic autoimmunity.

Mechanisms of Sex Disparities in Cardiovascular Function and Remodeling

Epidemiological studies demonstrate disparities between men and women in cardiovascular disease prevalence, clinical symptoms, treatments, and outcomes. Enrollment of women in clinical trials is lower than men, and experimental studies investigating molecular mechanisms and efficacy of certain therapeutics in cardiovascular disease have been primarily conducted in male animals. These practices bias data interpretation and limit the implication of research findings in female clinical populations. This review will focus on the biological origins of sex differences in cardiovascular physiology, health, and disease, with an emphasis on the sex hormones, estrogen and testosterone. First, we will briefly discuss epidemiological evidence of sex disparities in cardiovascular disease prevalence and clinical manifestation. Second, we will describe studies suggesting sexual dimorphism in normal cardiovascular function from fetal life to older age. Third, we will summarize and critically discuss the current literature regarding the molecular mechanisms underlying the effects of estrogens and androgens on cardiac and vascular physiology and the contribution of these hormones to sex differences in cardiovascular disease. Fourth, we will present cardiovascular disease risk factors that are positively associated with the female sex, and thus, contributing to increased cardiovascular risk in women. We conclude that inclusion of both men and women in the investigation of the role of estrogens and androgens in cardiovascular physiology will advance our understanding of the mechanisms underlying sex differences in cardiovascular disease. In addition, investigating the role of sex-specific factors in the development of cardiovascular disease will reduce sex and gender disparities in the treatment and diagnosis of cardiovascular disease. © 2019 American Physiological Society.

Established and novel pathophysiological mechanisms of pericardial injury and constrictive pericarditis

This review article aims to: (1) discern from the literature the immune and inflammatory processes occurring in the pericardium following injury; and (2) to delve into the molecular mechanisms which may play a role in the progression to constrictive pericarditis. Pericarditis arises as a result of a wide spectrum of pathologies of both infectious and non-infectious aetiology, which lead to various degrees of fibrogenesis. Current understanding of the sequence of molecular events leading to pathological manifestations of constrictive pericarditis is poor. The identification of key mechanisms and pathways common to most fibrotic events in the pericardium can aid in the design and development of novel interventions for the prevention and management of constriction. We have identified through this review various cellular events and signalling cascades which are likely to contribute to the pathological fibrotic phenotype. An initial classical pattern of inflammation arises as a result of insult to the pericardium and can exacerbate into an exaggerated or prolonged inflammatory state. Whilst the implication of major drivers of inflammation and fibrosis such as tumour necrosis factor and transforming growth factor β were foreseeable, the identification of pericardial deregulation of other mediators (basic fibroblast growth factor, galectin-3 and the tetrapeptide Ac-SDKP) provides important avenues for further research.

Symptomatic cardiac rheumatoid nodules are a rare but recognized manifestation of rheumatoid arthritis. We describe the surgical management of a rheumatic nodule involving the anterior leaflet of the mitral valve.

EXTRA-ARTICULAR MANIFESTATIONS OF RHEUMATOID ARTHRITIS

Rheumatoid arthritis (RA) is an immune inflammatory (autoimmune) rheumatic disease of unknown etiology, which is characterized by chronic erosive arthritis and systemic damage to the viscera, and leads to early disability and reduced survival in patients. For its diagnosis, it is currently recommended to use the 2010 ACR/EULAR classification criteria for RA, which should be applied in clinical trials to identify at least one swollen joint, i.e. the presence of arthritis; therefore, the problem of extra-articular manifestations of RA is apparent to stay in the background.

Mesenchymal TNFR2 promotes the development of polyarthritis and comorbid heart valve stenosis

Mesenchymal TNF signaling is etiopathogenic for inflammatory diseases such as rheumatoid arthritis and spondyloarthritis (SpA). The role of Tnfr1 in arthritis has been documented; however, Tnfr2 functions are unknown. Here, we investigate the mesenchymal-specific role of Tnfr2 in the TnfΔARE mouse model of SpA in arthritis and heart valve stenosis comorbidity by cell-specific, Col6a1-cre-driven gene targeting. We find that TNF/Tnfr2 signaling in resident synovial fibroblasts (SFs) and valvular interstitial cells (VICs) is detrimental for both pathologies, pointing to common cellular mechanisms. In contrast, systemic Tnfr2 provides protective signaling, since its complete deletion leads to severe deterioration of both pathologies. SFs and VICs lacking Tnfr2 fail to acquire pathogenic activated phenotypes and display increased expression of antiinflammatory cytokines associated with decreased Akt signaling. Comparative RNA sequencing experiments showed that the majority of the deregulated pathways in TnfΔARE mesenchymal-origin SFs and VICs, including proliferation, inflammation, migration, and disease-specific genes, are regulated by Tnfr2; thus, in its absence, they are maintained in a quiescent nonpathogenic state. Our data indicate a pleiotropy of Tnfr2 functions, with mesenchymal Tnfr2 driving cell activation and arthritis/valve stenosis pathogenesis only in the presence of systemic Tnfr2, whereas nonmesenchymal Tnfr2 overcomes this function, providing protective signals and, thus, containing both pathologies.

Comorbid TNF-mediated heart valve disease and chronic polyarthritis share common mesenchymal cell-mediated aetiopathogenesis

Objectives

Patients with rheumatoid arthritis and spondyloarthritisshow higher mortality rates, mainly caused by cardiac comorbidities. The TghuTNF (Tg197) arthritis model develops tumour necrosis factor (TNF)-driven and mesenchymalsynovial fibroblast (SF)-dependent polyarthritis. Here, we investigate whether this model develops, similarly to human patients, comorbid heart pathology and explore cellular and molecular mechanisms linking arthritis to cardiac comorbidities.

Methods

Histopathological analysis and echocardiographic evaluation of cardiac function were performed in the Tg197 model. Valve interstitial cells (VICs) were targeted by mice carrying the ColVI-Cretransgene. Tg197 ColVI-Cre Tnfr1^fl/fl and Tg197 ColVI-Cre Tnfr1^cneo/cneo mutant mice were used to explore the role of mesenchymal TNF signalling in the development of heart valve disease. Pathogenic VICs and SFs were further analysed by comparative RNA-sequencing analysis.

Results

Tg197 mice develop left-sided heart valve disease, characterised by valvular fibrosis with minimal signs of inflammation. Thickened valve areas consist almost entirely of hyperproliferative ColVI-expressing mesenchymal VICs. Development of pathology results in valve stenosis and left ventricular dysfunction, accompanied by arrhythmic episodes and, occasionally, valvular regurgitation. TNF dependency of the pathology was indicated by disease modulation following pharmacological inhibition or mesenchymal-specific genetic ablation or activation of TNF/TNFR1 signalling. Tg197-derived VICs exhibited an activated phenotype ex vivo, reminiscent of the activated pathogenic phenotype of Tg197-derived SFs. Significant functional similarities between SFs and VICs were revealed by RNA-seq analysis, demonstrating common cellular mechanisms underlying TNF-mediated arthritides and cardiac comorbidities.

Conclusions

Comorbidheart valve disease and chronic polyarthritis are efficiently modelled in the Tg197 arthritis model and share common TNF/TNFR1-mediated, mesenchymal cell-specific aetiopathogenic mechanisms.
