Heart involvement in rheumatoid arthritis: systematic review and meta-analysis

Proposal of a radiation-free screening protocol for early detection of interstitial lung involvement in seropositive and ACPA-positive rheumatoid arthritis

BACKGROUND

Seropositive rheumatoid arthritis (RA) is associated with significant cardiovascular and pulmonary morbidity. However, screening for early detection of pulmonary involvement especially interstitial lung disease (ILD) is not established in RA.

METHODS

We propose a non-invasive radiation-free approach to screen for interstitial lung involvement (ILI) by means of pulmonary function tests (PFT) and pleuro-pulmonary transthoracic ultrasound (LUS) with additional cardiopulmonary exercise tests (CPET) with ECG, and echocardiography. We included patients with confirmed diagnosis of seropositive RA according to ACR criteria, but without symptoms for or known cardiopulmonary disease. ILD was suspected when significant LUS abnormalities and additional PFT changes were present.

RESULTS

We included 67 consecutive patients (78% female, mean age 61 ± 12 years, 48% active or previous smokers), who fulfilled the inclusion criteria and gave written informed consent. We found 48% of patients with suspected changes in PFT with a diffusion capacity (DLCOc-SB) ≤ 80%, among them 7% with forced vital capacity (FVC) ≤ 80%. In 40% of patients, we found noticeable changes in LUS, 24% with an ILD compatible pattern. In 16% of cases, LUS abnormalities and additional PFT changes were present, and ILI was suspected. Additional findings included obstructive lung disease (n = 11), subpleural consolidation (n = 6) including one confirmed lung cancer, minimal pleural effusion (n = 6), and ischemic cardiac disease (n = 2). None of the patients showed signs of pulmonary vascular involvement.

CONCLUSIONS

ILI was suspected in 16% of cases using a new radiation-free screening protocol in asymptomatic RA patients.

Aortic Regurgitation and Rheumatoid Arthritis

Rheumatoid cardiac nodules are a rare finding in patients with seropositive rheumatoid arthritis. They infrequently become symptomatic but can present as valvular insufficiency. A 53-year-old man with rheumatoid arthritis was found to have worsening aortic insufficiency. Echocardiography revealed nodular densities on the valve, consistent with rheumatoid nodules, causing significant regurgitation.

Managing rheumatoid arthritis and cardiovascular disease: the role of physical medicine and rehabilitation

INTRODUCTION

Cardiovascular disease (CVD) presents a significant challenge in rheumatoid arthritis (RA), a systemic chronic ailment affecting the joints and causing systemic inflammation. Effective RA management, including pharmacological and non-pharmacological interventions, is crucial for mitigating cardiac risk. Pharmacotherapy, though effective, can have adverse effects, leading many patients to seek complementary therapies. This study investigates the impact of physical medicine and rehabilitation on RA management in patients with cardiovascular disease, analyzing clinical data to assess the efficacy of integrated therapeutic approaches.

METHODS

This retrospective monocentric study draws upon data from patient records at the Rheumatology Department of the Regional Clinical Hospital of Shymkent, Kazakhstan, spanning 2019 to 2022. Data collected included demographic information, diagnoses, comorbidities, medical anamneses, lab results, and treatment regimens, including physical medicine and rehabilitation interventions. Data were summarized in Microsoft Excel. Statistical analysis was performed using IBM SPSS Statistics (version 26.0).

RESULTS

An analysis of 350 patients with RA identified 143 cases of concomitant CVD, with arterial hypertension being the most common cardiovascular disease. The prevalence of CVD among patients with RA was 40%, with a mean age of 58 years, peaking between 50 and 65 years. The majority of patients were women. A strong association was found between increased RA activity and elevated cardiovascular risk. Despite the widespread use of glucocorticosteroid therapy, rehabilitation coverage remained limited. A significant proportion of patients had elevated cholesterol and C-reactive protein levels, while those who engaged in physical therapy and rehabilitation had lower cholesterol levels. Comparative analysis of yoga integration into rehabilitation programs for patients with RA, alongside other modalities (kinesiotherapy, balneotherapy, and pilates), showed that yoga participants exhibited lower pain levels, reduced morning stiffness duration, and lower mean DAS-28 scores compared to those using alternative rehabilitation methods.

CONCLUSION

Integrating physical medicine and rehabilitation, particularly yoga, with pharmacological treatments appears promising for improving patient outcomes. Yoga has demonstrated benefits in reducing pain, morning stiffness, and disease activity. Continued research is essential to refine these approaches and enhance RA and CVD management in patients.

Rheumatoid arthritis, cardiometabolic comorbidities, and related conditions: need to take action

Rheumatoid Arthritis (RA) is associated with an increased risk of cardiovascular disease and mortality, however, traditional cardiovascular risk factors do not fully explain this relationship. This high risk of cardiovascular morbidity and mortality in RA has been increasingly acknowledged in past decades, with accumulating evidence that RA is an independent cardiovascular risk factor; RA is also associated with metabolic syndrome, which correlates with disease activity, contributing to the increased prevalence of coronary heart disease in RA patients. Moreover, multimorbidity, including the presence of long-term conditions, impacts adverse clinical outcomes in RA patients, emphasizing the need for holistic management that requires an understanding of shared pathophysiological mechanisms, such as systemic inflammation and immune dysregulation. For all these reasons, the management of RA patients with cardiometabolic comorbidities is a complex endeavor that requires a patient-centered, multidisciplinary approach. In this sense, there is a need to re-evaluate the approach toward a proactive model of care, moving away from a reactive medical paradigm to a multidimensional integrated management model, including aggressive screening, preventive strategies, and tailored therapeutic interventions. The aim of this review was to thoroughly review the literature on cardiometabolic comorbidities and related conditions linked to RA to enable us to identify the necessary actions required to effectively tackle the increasing burden of illness from a fully comprehensive perspective.

Cardiovascular multimodality imaging in women: a scientific statement of the European Association of Cardiovascular Imaging of the European Society of Cardiology

Cardiovascular diseases (CVD) represent an important cause of mortality and morbidity in women. It is now recognized that there are sex differences regarding the prevalence and the clinical significance of the traditional cardiovascular (CV) risk factors as well as the pathology underlying a range of CVDs. Unfortunately, women have been under-represented in most CVD imaging studies and trials regarding diagnosis, prognosis, and therapeutics. There is therefore a clear need for further investigation of how CVD affects women along their life span. Multimodality CV imaging plays a key role in the diagnosis of CVD in women as well as in prognosis, decision-making, and monitoring of therapeutics and interventions. However, multimodality imaging in women requires specific consideration given the differences in CVD between the sexes. These differences relate to physiological changes that only women experience (e.g. pregnancy and menopause) as well as variation in the underlying pathophysiology of CVD and also differences in the prevalence of certain conditions such as connective tissue disorders, Takotsubo, and spontaneous coronary artery dissection, which are all more common in women. This scientific statement on CV multimodality in women, an initiative of the European Association of Cardiovascular Imaging of the European Society of Cardiology, reviews the role of multimodality CV imaging in the diagnosis, management, and risk stratification of CVD, as well as highlights important gaps in our knowledge that require further investigation.

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.

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.

Cardiac tamponade

Cardiac tamponade is a medical emergency caused by the progressive accumulation of pericardial fluid (effusion), blood, pus or air in the pericardium, compressing the heart chambers and leading to haemodynamic compromise, circulatory shock, cardiac arrest and death. Pericardial diseases of any aetiology as well as complications of interventional and surgical procedures or chest trauma can cause cardiac tamponade. Tamponade can be precipitated in patients with pericardial effusion by dehydration or exposure to certain medications, particularly vasodilators or intravenous diuretics. Key clinical findings in patients with cardiac tamponade are hypotension, increased jugular venous pressure and distant heart sounds (Beck triad). Dyspnoea can progress to orthopnoea (with no rales on lung auscultation) accompanied by weakness, fatigue, tachycardia and oliguria. In tamponade caused by acute pericarditis, the patient can experience fever and typical chest pain increasing on inspiration and radiating to the trapezius ridge. Generally, cardiac tamponade is a clinical diagnosis that can be confirmed using various imaging modalities, principally echocardiography. Cardiac tamponade is preferably resolved by echocardiography-guided pericardiocentesis. In patients who have recently undergone cardiac surgery and in those with neoplastic infiltration, effusive-constrictive pericarditis, or loculated effusions, fluoroscopic guidance can increase the feasibility and safety of the procedure. Surgical management is indicated in patients with aortic dissection, chest trauma, bleeding or purulent infection that cannot be controlled percutaneously. After pericardiocentesis or pericardiotomy, NSAIDs and colchicine can be considered to prevent recurrence and effusive-constrictive pericarditis.

Inflammatory and thrombotic valvulopathies in autoimmune disease

Rheumatologic diseases are characterised by loss of immune tolerance, resulting in systemic inflammation. Inflammation and scarring of the endocardium, which lines the inner surface of the heart chambers and valves, can result in valvular thickening and dysfunction. Estimates of prevalence vary depending on the sensitivity of the screening methodology used and range from 30%-50% in systemic lupus and rheumatoid arthritis to 10%-30% in ankylosing spondylitis. Progression of valve disease is a slow process but can result in haemodynamically significant complications. Thromboembolic complications such as cerebrovascular occlusions pose a serious risk of morbidity. The presence of antiphospholipid antibodies increases the risk of valvular disease and thrombotic complications. Anticoagulation is recommended in the presence of antiphospholipid antibodies, but the guidance on the role of immunosuppressive therapy to treat valvular disease is lacking. Surgical valve therapy may be considered in severe disease, but there is increased risk in patients with an autoimmune disease which includes a higher risk of infection, thromboembolic and bleeding complications, as well as cardiovascular events in the setting of premature atherosclerotic heart disease. Therefore, management should be provided in a multidisciplinary team that includes a rheumatologist, a cardiologist and a cardiothoracic surgeon; medical therapy should be optimised before considering a high-risk valve surgery.

Changes in Thyroid Hormone Signaling Mediate Cardiac Dysfunction in the Tg197 Mouse Model of Arthritis: Potential Therapeutic Implications

Background Rheumatoid Arthritis (RA) patients show a higher risk of heart failure. The present study investigated possible causes of cardiac dysfunction related to thyroid hormone (TH) signaling in a RA mouse model. Methods A TNF-driven mouse model of RA[TghuTNF (Tg197)] was used. Cardiac function was evaluated by echocardiography. SERCA2a and phospholamban protein levels in left ventricle (LV) tissue, thyroid hormone levels in serum, TH receptors in LV and TH-related kinase signaling pathways were measured. T3 hormone was administered in female Tg197 mice. Results We show LV and atrial dilatation with systolic dysfunction in Tg197 animals, accompanied by downregulated SERCA2a. We suggest an interaction of pro-inflammatory and thyroid hormone signaling indicated by increased p38 MAPK and downregulation of TRβ1 receptor in Tg197 hearts. Interestingly, female Tg197 mice showed a worse cardiac phenotype related to reduced T3 levels and Akt activation. T3 supplementation increased Akt activation, restored SERCA2a expression and improved cardiac function in female Tg197 mice. Conclusions TNF overexpression of Tg197 mice results in cardiac dysfunction via p38 MAPK activation and downregulation of TRβ1. Gender-specific reduction in T3 levels could cause the worse cardiac phenotype observed in female mice, while T3 administration improves cardiac function and calcium handling via modified Akt activation.

Valve Abnormalities, Risk Factors for Heart Valve Disease and Valve Replacement Surgery in Spondyloarthritis. A Systematic Review of the Literature

Objective: Evaluate the evidence on the abnormalities of the aortic root and heart valves, risk and prognostic factors for heart valve disease and valve replacement surgery in spondyloarthritis.

Methods: A systematic literature review was performed using Medline, EMBASE and Cochrane databases until July 2021. Prevalence, incidence, risk and prognostic factors for heart valve disease; dimension, morphology, and pathological abnormalities of the valves were analyzed. Patient characteristics (younger age, history of cardiac disease or longer disease duration) and period of realization were considered for the analysis. The SIGN Approach was used for rating the quality of the evidence of the studies.

Results: In total, 37 out of 555 studies were included. Overall, the level of evidence was low. The incidence of aortic insufficiency was 2.5–3.9‰. Hazard Ratio for aortic insufficiency was 1.8–2.0. Relative risk for aortic valve replacement surgery in ankylosing spondylitis patients was 1.22–1.46. Odds ratio for aortic insufficiency was 1.07 for age and 1.05 for disease duration. Mitral valve abnormalities described were mitral valve prolapse, calcification, and thickening. Aortic valve abnormalities described were calcification, thickening and an echocardiographic “subaortic bump.” Abnormalities of the aorta described were thickening of the wall and aortic root dilatation. The most common microscopic findings were scarring of the adventitia, lymphocytic infiltration, and intimal proliferation.

Conclusions: A higher prevalence and risk of aortic valve disease is observed in patients with ankylosing spondylitis. Studies were heterogeneous and analysis was not adjusted by potential confounders. Most studies did not define accurate outcomes and may have detected small effects as being statistically significant.

Ischemic Heart Disease and Rheumatoid Arthritis-Two Conditions, the Same Background

Rheumatoid arthritis (RA) is one of the most frequent inflammatory rheumatic diseases, having a considerably increased prevalence of mortality and morbidity due to cardiovascular disease (CVD). RA patients have an augmented risk for ischemic and non-ischemic heart disease. Increased cardiovascular (CV) risk is related to disease activity and chronic inflammation. Traditional risk factors and RA-related characteristics participate in vascular involvement, inducing subclinical changes in coronary microcirculation. RA is considered an independent risk factor for coronary artery disease (CAD). Endothelial dysfunction is a precocious marker of atherosclerosis (ATS). Pro-inflammatory cytokines (such as TNFα, IL-1, and IL-6) play an important role in synovial inflammation and ATS progression. Therefore, targeting inflammation is essential to controlling RA and preventing CVD. Present guidelines emphasize the importance of disease control, but studies show that RA- treatment has a different influence on CV risk. Based on the excessive risk for CV events in RA, permanent evaluation of CVD in these patients is critical. CVD risk calculators, designed for the general population, do not use RA-related predictive determinants; also, new scores that take into account RA-derived factors have restricted validity, with none of them encompassing imaging modalities or specific biomarkers involved in RA activity.

Long-Term Outcomes of Surgical Aortic Valve Replacement in Patients with Rheumatoid Arthritis

Background: Patients with rheumatoid arthritis (RA) have increased risk of developing cardiovascular disease and events. Little is, however, known about the influence of RA to the outcomes after surgical aortic valve replacement (SAVR). Methods: In a retrospective, nationwide, multicenter cohort study, RA patients (n = 109) were compared to patients without RA (n = 1090) treated with isolated SAVR for aortic valve stenosis. Propensity score-matching adjustment for baseline features was used to study the outcome differences in a median follow-up of 5.6 years. Results: Patients with RA had higher all-cause mortality (HR 1.76; CI 1.21–2.57; p = 0.003), higher incidence of major adverse cardiovascular events (HR 1.63; CI 1.06–2.49; p = 0.025), and they needed more often coronary artery revascularization for coronary artery disease (HR 3.96; CI 1.21–12.90; p = 0.027) in long-term follow-up after SAVR. As well, cardiovascular mortality rate was higher in patients with RA (35.7% vs. 23.4%, p = 0.023). There was no difference in 30-day mortality (2.8% vs. 1.8%, p = 0.518) or in the need for aortic valve reoperations (3.7% vs. 4.0%, p = 0.532). Conclusions: Patients with rheumatoid arthritis had impaired long-term results and increased cardiovascular mortality after SAVR for aortic valve stenosis. Special attention is needed to improve outcomes of aortic valve stenosis patients with RA after SAVR.

Frequency of Cardiovascular Manifestation in Patients With Rheumatoid Arthritis

Introduction

Rheumatoid arthritis (RA) is a chronic, inflammatory, systemic autoimmune disease. The increased inflammatory burden in RA may result in atherosclerosis, myocardial infarction (MI), and subsequent mortality. In this study, we will determine the frequency of cardiovascular manifestation in RA patients through history, laboratory workup, and echocardiography.

Methods

This cross-sectional study was conducted in the rheumatology unit of a tertiary care hospital in Pakistan. Three hundred and twenty-two (n=322) participants with a previously confirmed diagnosis of RA were enrolled in this study via consecutive convenient non-probability sampling.

Results

Cardiovascular manifestations were present in 188 (58.3%) participants. More participants had positive rheumatoid factor (82.9% vs. 32.8%; p-value: < 0.0001) in RA patients with cardiovascular manifestation compared to RA patients without cardiovascular manifestation. Patients with cardiovascular manifestations have a significantly higher C-reactive protein (CRP; 10.21 ± 2.81 mg/L vs. 8.17± 2.01 mg/L; p value: < 0.0001) and erythrocyte sedimentation rate (ESR; 16.2 ± 3.14 mg/L vs. 15.1 ± 2.99 mg/L; p value: 0.0017).

Conclusion

In this study, patients with a cardiovascular manifestation had a higher frequency of patients with rheumatoid factor, higher mean values of CRP and ESR. The early diagnosis and management of cardiac manifestations would aid in controlling the severity of the disease and the overall mortality.

Pathogenesis of ischaemic and non-ischaemic heart diseases in rheumatoid arthritis

Rheumatoid arthritis (RA) is characterised by a chronic inflammatory condition of the joints, but the comorbidities of RA predominantly contribute to the reduced lifespan associated with this disease. Clinical data indicate that cardiovascular disease is the major comorbidity associated with mortality in RA. In this review, we aimed to describe the pathogenesis of heart failure in RA. First, we emphasised the fundamental differences between ischaemic and non-ischaemic heart diseases and referred to their relevance in excessive cardiovascular-dependent mortality in RA. Second, we highlighted aspects of asymptomatic changes in cardiac tissue and in coronary blood vessels that are commonly found in patients with diagnosed RA. Third, we focused on high-grade systemic inflammation as a key trigger of ischaemic and non-ischaemic heart diseases in RA, and described the implication of conventional and biologic antirheumatic medications on the development and progression of heart disease. In particular, we discussed the roles of tumour necrosis factor-alpha (TNF-α) and anti-TNF-α therapies on the development and progression of ischaemic and non-ischaemic heart diseases in RA.

DBA/1 mice display equivalent cardiac function to C57BL/6J mice

NEW FINDINGS

What is the central question of this study? Do normal adult DBA/1 mice have cardiac function and performance equal to those of C57BL/6J mice? What is the main finding and its importance? Male adult DBA/1 mice show equivalent cardiac function to C57BL/6J mice up to 8 months old. Therefore, cardiac dysfunction could be investigated in an autoimmune diseases model established with DBA/1 mice.

ABSTRACT

Cardiovascular mortality has been increasing, and in particular, cardiovascular damage caused by some chronic autoimmune diseases accounts for a large proportion of this. C57BL/6J mice have been used mostly in studies of cardiovascular diseases. However, for purposes of modelling, this strain of mouse has a very low incidence of some chronic immune diseases such as rheumatoid arthritis, to which instead DBA/1 mice are more susceptible. Basic cardiac function differs between mice with different genetic backgrounds. Therefore, we monitored cardiac function and structure of normal male C57BL/6J and DBA/1 mice for six consecutive months. Echocardiography was used to monitor cardiac functions once a month and cardiac systolic function was measured upon isoproterenol challenge at the end of observation. The Excitation-contraction coupling-related proteins were measured by western blotting. Heart tissue sections were subject to haematoxylin-eosin, TUNEL and Alizarin red staining. The results demonstrated that systolic and diastolic function did not vary significantly and both strains were indistinguishable in appearance and structure of hearts. DBA/1 mice showed a good cardiac β-adrenergic response comparable to C57BL/6J mice with isoproterenol treatment. The phosphorylation of phospholamban at either its protein kinase A or its Ca²⁺ /calmodulin-dependent protein kinase II site, as well as the activation of troponin I showed no significant difference between strains. These findings suggested that there was no obvious difference in the heart structure and function of normal male DBA/1 mice compared with C57BL/6J mice. The DBA/1 mouse is a strain applicable to investigating autoimmune disease-induced heart dysfunction and exploring potential interventions.

Rheumatoid arthritis mimicking infective endocarditis with severe aortic regurgitation and aortic root abscess: a case report

Background

Rheumatoid arthritis (RA) may involve the cardiovascular system and can cause significant structural cardiac disease. RA mimicking infective endocarditis (IE) is rarely reported.

Case summary

A 46-year-old man with a medical history of seropositive RA attended a planned outpatient visit for infliximab treatment. The pre-infusion examination revealed a pulse of 41 b.p.m. and the following electrocardiogram showed 3rd degree atrioventricular block. A temporary pacemaker was inserted, and subsequent transthoracic and transoesophageal echocardiograms showed severe aortic valve regurgitation with thickened cusps and thus raised suspicion of infective aortic endocarditis with root abscess. The patient underwent surgery with valve and root replacement the next day. What was thought to be IE, proved to be suppurative and granulomatous inflammation with sporadic necrosis and hyaline fibrosis, compatible with a rheumatoid nodule linked to the patient’s RA diagnosis.

Discussion

IE is a disease with high mortality and morbidity. In some cases of IE perivalvular cavities develop, most commonly abscesses and/or pseudoaneurysms, which necessitates surgery. Several conditions may mimic IE: for example, malignant and benign tumours, rheumatic diseases, and common age-related valve calcification. In patients with valvular vegetations that are ‘culture-negative’, alternative pathologies should be considered.

Concomitant Large Loculated Pleural and Pericardial Effusions in a Patient with Rheumatoid Arthritis on Methotrexate

Rheumatoid arthritis (RA) is the most common multisystemic autoimmune inflammatory joint disorder, affecting nearly 1.3 million adults in the US. RA has high economic and social burdens. Functional disability may arise in RA from the characteristic chronic progressive inflammation and the erosion of multiple joints and cartilage damage. Systemic manifestations of RA include rheumatoid nodules, pleuropulmonary complications, pericarditis, rheumatoid vasculitis, Felty's syndrome (the rare triad of rheumatoid arthritis, splenomegaly, and neutropenia), amyloidosis, and neurological complications. We present the diagnostic challenges of differentiating pleuropulmonary and pericardial complications of rheumatoid arthritis from side effects of therapy (rheumatoid pleural and pericardial effusions vs immune suppression associated side effects and infections). We use the Naranjo score to facilitate this decision-making process. A 52-year-old man with a history of RA, chronic small right pleural effusion, and hypertension on long-term oral methotrexate and corticosteroid therapy presented to the emergency room after 1 week of worsening respiratory symptoms. A chest radiograph demonstrated a large pleural effusion and pneumonia. Intravenous methylprednisolone and antibiotics were administered. A video-assisted thoracoscopic procedure was performed, chest tubes were inserted, and abatacept was eventually initiated as adjunctive therapy to methotrexate and corticosteroid therapy for the rheumatoid arthritis and lung condition. Abatacept is an immunosuppressive fusion protein composed of the Fc region of immunoglobulin G1 fused to the extracellular domain of cytotoxic T-lymphocyte-associated protein 4, which interferes with the immune activity of T cells.

Endothelial Dysfunction and Extra-Articular Neurological Manifestations in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory autoimmune disease that affects about 1% of the global population, with a female–male ratio of 3:1. RA preferably affects the joints, with consequent joint swelling and deformities followed by ankylosis. However, evidence has accumulated showing that patients suffering from RA can also develop extra-articular manifestations, including cardiovascular disease states, neuropathies, and multiorgan dysfunction. In particular, peripheral nerve disorders showed a consistent impact in the course of the disease (prevalence about 20%) mostly associated to vasculitis of the nerve vessels leading to vascular ischemia, axonal degeneration, and neuronal demyelination. The pathophysiological basis of this RA-associated microvascular disease, which leads to impairment of assonal functionality, is still to be better clarified. However, endothelial dysfunction and alterations of the so-called brain-nerve barrier (BNB) seem to play a fundamental role. This review aims to assess the potential mechanisms underlying the impairment of endothelial cell functionality in the development of RA and to identify the role of dysfunctional endothelium as a causative mechanism of extra-articular manifestation of RA. On the other hand, the potential impact of lifestyle and nutritional interventions targeting the maintenance of endothelial cell integrity in patients with RA will be discussed as a potential option when approaching therapeutic solutions in the course of the disease.

Thoracic Manifestations of Rheumatoid Arthritis

Rheumatoid arthritis (RA) is one of the most common chronic systemic inflammatory diseases and the most common chronic inflammatory arthritis. Classically a progressive symmetric polyarthritis, RA is characterized by inflammation, erosions, bone loss, and joint destruction. Up to half of patients with RA exhibit extra-articular manifestations (EAMs), which may precede articular disease and are more common in patients with seropositive RA (patients with detectable serum levels of rheumatoid factor and/or anticitrullinated peptide antibodies). Cardiovascular and pulmonary EAMs are the largest contributors to morbidity and mortality in RA and may be especially devastating. Imaging has a significant role in diagnosing these EAMs and assessing response to treatment. Although treatment with disease-modifying antirheumatic drugs has redefined the natural history of RA and helped many patients achieve low disease activity, patients are at risk for treatment-related complications, as well as infections. The clinical features of drug-induced lung disease and infection can overlap considerably with those of EAMs, presenting a diagnostic challenge. Radiologists, by recognizing the imaging characteristics and evolution of these various processes, are essential in diagnosing and distinguishing among EAMs, treatment-related complications, and unrelated processes and formulating an appropriate differential diagnosis. Moreover, recognizing these disease processes at imaging and contextualizing imaging findings with clinical information and laboratory and pathologic findings can facilitate definitive diagnosis and proper treatment. The authors review the articular and extra-articular thoracic imaging manifestations of RA, including cardiovascular, respiratory, and pleural diseases, as well as treatment-related complications and common infections. ^©RSNA, 2021.

Cardiovascular Risk of Synthetic, Non-Biologic Disease-Modifying Anti- Rheumatic Drugs (DMARDs)

Patients with rheumatoid diseases have an increased risk of cardiovascular disease (CVD) and CVD-related death compared with the general population. Both the traditional cardiovascular risk factors and systemic inflammation are contributors to this phenomenon. This review examines the available evidence about the effects of synthetic, non-biologic disease-modifying antirheumatic drugs (DMARDs) on CVD risk. This is an important issue for clinicians when deciding on individual treatment plans in patients with rheumatic diseases. Evidence suggests that synthetic, non-biologic DMARDs such as methotrexate, sulfasalazine, hydroxychloroquine, leflunomide and tofacitinib show decreased CVD morbidity and mortality. However, the strongest data in favour of a reduction in CVD events in rheumatoid patients are shown with methotrexate, which has been the focus of most studies. Adequate proof for a favourable effect also exists for hydroxychloroquine. Larger, prospective studies and randomized clinical trials are needed to better characterize the effect of synthetic, non-biologic DMARDs on CVD outcomes in these patients. Design of future studies should include areas with lack of evidence, such as the risk for heart failure, arrhythmias and valvular heart disease. The clinically relevant question whether synthetic, non-biologic DMARDs are inferior to biologic DMARDs in terms of CVD outcomes remains not adequately addressed.

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.

Identification of key genes in calcific aortic valve disease by integrated bioinformatics analysis

Calcific aortic valve disease (CAVD) is highly prevalent in our aging world and has no effective pharmaceutical treatment. Intense efforts have been made but the underlying molecular mechanisms of CAVD are still unclear.This study was designed to identify the critical genes and pathways in CAVD by bioinformatics analysis. Microarray datasets of GSE12644, GSE51472, and GSE83453 were obtained from Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified and functional and pathway enrichment analysis was performed. Subsequently, the protein-protein interaction network (PPI) was constructed with Search Tool for the Retrieval of Interacting Genes and was visualized with Cytoscape to identify the most significant module. Hub genes were identified by Cytoscape plugin cytoHubba.A total of 179 DEGs, including 101 upregulated genes and 78 downregulated genes, were identified. The enriched functions and pathways of the DEGs include inflammatory and immune response, chemotaxis, extracellular matrix (ECM) organization, complement and coagulation cascades, ECM receptor interaction, and focal adhesion. The most significant module in the PPI network was analyzed and genes among it were mainly enriched in chemotaxis, locomotory behavior, immune response, chemokine signaling pathway, and extracellular space. In addition, DEGs, with degrees ≥ 10 and the top 10 highest Maximal Chique Centrality (MCC) score, were identified as hub genes. CCR1, MMP9, VCAM1, and ITGAX, which were of the highest degree or MCC score, were manually reviewed.The DEGs and hub genes identified in the present study help us understand the molecular mechanisms underlying the pathogenesis of CAVD and might serve as candidate therapeutic targets for CAVD.

Disorders of the Aorta and Aortic Valve in Connective Tissue Diseases

PURPOSE OF REVIEW

The incidence of aortic valve disease in inherited connective tissue disorders is well documented; however, recent studies have only begun to unravel the pathology behind this association. In this review, we aim to describe the etiology, clinical manifestations, management, and prognosis of aortic and aortic valvular disorders that co-exist in a variety of connective tissue diseases. An extensive literature review was performed in PubMed. Articles from 2008 to 2018 were included for review. Predetermined search terms used in PubMed include "aortic manifestation of connective tissue diseases" and "aortic valve disorders in rheumatologic disease."

RECENT FINDINGS

Manifestations of aortic valve disease in the context of connective tissue disorders include valvular stenosis, regurgitation, and/or thoracic aortic aneurysms. Both inherited and inflammatory connective tissue disorders contribute to aortic valve damage with increased susceptibility associated with specific gene variants. Anti-inflammatory and immunosuppressive therapies have demonstrated beneficial results in Marfan's syndrome, Behcet disease, rheumatoid arthritis, ankylosing spondylitis, and systemic sclerosis, often leading to remission. Yet, such therapy is less effective in other disorders compared to alternative treatments such as surgical intervention. Additionally, regular echocardiographic studies should be recommended to those suffering from these disorders, especially those at higher risk for cardiovascular involvement. Given the rates of relapse with immunosuppressants, even following aortic valve replacement, further studies are needed to determine if certain dosing and/or combinations of immunosuppressants could be given to those diagnosed with connective tissue diseases to prevent progression of aortic valve involvement.

The effects of exercise on cardiovascular disease risk factors and cardiovascular physiology in rheumatoid arthritis

Cardiovascular disease (CVD) morbidity and mortality is highly prevalent in patients with rheumatoid arthritis (RA) with debilitating effects for the individual as well as significant healthcare impact. Current evidence demonstrates that engaging in aerobic and resistance exercise (i.e. structured physical activity) can significantly improve patient-reported and clinical index-assessed outcomes in RA. In addition to this, engagement in exercise programmes improves, in a dose-dependent manner, the risk of developing CVD as well as CVD symptoms and outcomes. The present narrative review uses evidence from systematic reviews and meta-analyses as well as controlled trials, to synthesize the current state-of-the-art on the potential effects of aerobic and resistance exercise on CVD risk factors as well as on cardiac and vascular function and structure in people with RA. Where there is a lack of evidence in RA to explain potential mechanisms, relevant studies from the general population are also discussed and linked to RA.

Imaging for screening cardiovascular involvement in patients with systemic rheumatologic diseases: more questions than answers

Cardiovascular involvement due to systemic rheumatologic diseases (SRDs) remains largely underdiagnosed despite causing excess mortality and limiting the favourable effect of therapeutic developments on survival. Traditional risk scoring systems are poorly calibrated for SRD patients. There is an unmet need to develop a cardiovascular (CV) risk stratification tool and screening algorithm for CV involvement dedicated to asymptomatic patients with SRDs. Even though accelerated atherosclerosis is the most prominent cause of major CV events, a more comprehensive approach is crucial to detect different pathological processes associated with SRDs that are leading to CV complications. In that regard, incorporation of imaging parameters obtained from echocardiography and carotid ultrasound (CUS) might help to improve risk models, to detect and monitor subclinical CV involvement. These two imaging modalities should be an integral part of screening SRD patients with suspicion of CV involvement on top of electrocardiogram (ECG). Cardiac magnetic resonance and multi-slice computerized tomography angiography and nuclear imaging modalities seem very important to complement echocardiography and CUS for further evaluation. However, to answer the question ‘Should asymptomatic patients with SRDs undergo screening with echocardiography and CUS on top of ECG?’ necessitates large studies performing cardiac screening with a standard approach by using these imaging methods to obtain longitudinal data with hard CV outcomes.

Cardiac and vascular complications in rheumatoid arthritis

Rheumatoid arthritis (RA) is an independent risk factor for the development of a variety of cardiovascular diseases, with a 1.5-factor increase in risk. This literature review aims to provide a global overview of the pathogenesis, effects of anti-rheumatoid treatment on cardiovascular risk, a description of the cardiovascular complications associated with RA, and current opinion on cardiovascular risk assessment and management in patients with RA. Author conducted a literature search in PubMed, Scopus, Web of Science and Embase regarding RA and associated cardiovascular complications. The mechanism of increased risk of cardiovascular disease in patients with RA is complex. There are specific genetic factors associated with both diseases, and traditional cardiovascular risk factors may be more prevalent in patients with RA. Most anti-rheumatic drugs decrease cardiovascular risk, and general recommendations focus on reduction of disease activity and strict management of cardiovascular risk as per the general population.

Cardiovascular Comorbidity in Inflammatory Rheumatological Conditions

BACKGROUND

Approximately 1.5 million adults in Germany suffer from an inflammatory rheumatological condition. The most common among these are rheumatoid arthritis and spondyloarthritis-above all axial spondyloarthritis, including ankylosing spondylitis (Bekhterev's disease) and psoriatic arthritis. These systemic inflammatory diseases often affect the heart as well.

METHODS

This review is based on pertinent articles retrieved by a selective literature search, on current European guidelines, and on the authors' clinical experience.

RESULTS

Rheumatic inflammation of cardiac structures can manifest itself as pericarditis, myocarditis, or endocarditis. The heart valves and the intracardiac conduction system can be affected as well, leading to AV block. Functional sequelae, e.g., congestive heart failure, can arise as a consequence of any inflammatory rheumatic disease. The long-term mortality of rheumatic diseases is elevated predominantly because of the increased risk for cardiovascular comorbidities. The cardiovascular risk profile should therefore be re-evaluated regularly (e.g., at 5-year intervals) in cooperation with the patient's primary care physician. The cardiovascular manifestations of rheumatic disease, such as pericarditis, myocarditis, and vasculitis, are treated initially with high-dose glucocorticoids and then over the long term with maintenance drugs such as methotrexate and azathioprine. Biological agents are sometimes used as well.

CONCLUSION

In patients with inflammatory rheumatic diseases, the elevated cardiovascular risk should be kept in mind and preventive measures should be initiated early. This subject should be further studied in controlled trials so that the treatment options for patients with cardiac involvement can be evaluated.

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 Tnfr1fl/fl and Tg197 ColVI-Cre Tnfr1cneo/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.

One-Year Follow-up Study Detects Myocardial Changes with Cardiovascular Magnetic Resonance Tagging in Active Rheumatoid Arthritis

RATIONALE AND OBJECTIVES

To evaluate the effects of 1 year of medical treatment on myocardial function in active rheumatoid arthritis (RA).

MATERIALS AND METHODS

Thirty-nine female patients with RA without any known cardiovascular disease underwent a cardiovascular magnetic resonance (CMR) examination before and after 1 year of antirheumatic treatment. The population comprised untreated active early RA (ERA) and chronic RA patients, who were grouped accordingly. The CMR protocol included volumetric determinations, late gadolinium enhancement imaging, myocardial tagging, and native T1 mapping. DAS28-CRP disease activity scores were calculated before and after the treatment.

RESULTS

Results are reported as median (quartile 1-quartile 3). Time to peak diastolic filling rate improved in ERA (495 [443-561] ms vs 441 [340-518] ms, P = .018). Peak diastolic mean mid short-axis circumferential strain rate of all six segments was improved (82 [74-91] %/s vs 91 [77-100] %/s, P = .05), particularly in the anterior segment (82 [63-98] %/s vs 86 [77-109] %/s, P = .013). DAS28-CRP decreased in ERA (3.8 [3.2-4.1] vs 1.6 [1.4-2.2], P < .001). In chronic RA, no statistically significant improvement was detected.

CONCLUSIONS

Early treatment of active RA is important, as myocardial function detected with CMR tagging improved in ERA in parallel with decreasing inflammatory activity.

Echocardiography in the Assessment of Patients with Rheumatologic Diseases

Cardiovascular disease is an important extra-articular manifestation of rheumatologic diseases leading to considerable mortality and morbidity. Echocardiography emerges as a useful non-invasive technique for the screening and evaluation of cardiac involvement in these patients. With the technological advancement in echocardiographic techniques, we have gained a greater appreciation of the prevalence and nature of the cardiac involvement in these patients, as detection of subclinical disease is increasingly feasible. This review discusses cardiac involvement in patients with rheumatoid arthritis, systemic lupus erythematosus, anti-phospholipid antibody syndrome, systemic sclerosis and ankylosing spondylitis, and the role of different echocardiographic modalities in their evaluation.

Chest Pain Due to Pericardial Effusion as Initial Presenting Feature of Rheumatoid Arthritis: Case Report and Review of the Literature

Pericardial effusions are not uncommon in rheumatoid arthritis (RA); however, they are rarely the presenting symptom of the disease. We describe a 55-year-old female who presented to the emergency department with complaints of chest pain and dyspnea on exertion. Initial workup revealed a medium-sized pericardial effusion. The wide spectrum of etiologies, including infectious and non-infectious disease, was explored. Eventually, after ruling out an array of disease states, rheumatologic workup was positive for RA. The initial presentation in our case was atypical due to absence of small joint polyarthritis and other common symptoms of RA. In difficult cases, extensive workup including laboratory tests, electrocardiography, echocardiography and imaging studies can aid in narrowing the causes of pericardial effusion. This case demonstrates that pericardial effusion could be an early presenting feature of RA, even in the absence of more common symptoms, and should be considered in differential diagnosis.

Features of cardiac remodeling in Patients with Acute Coronary Syndrome Complicated with Rheumatoid Arthritis

Cardiovascular diseases are important factors to increased morbidity and mortality in patients with rheumatoid arthritis (RA). The aim of this study is to investigate the effects of RA on cardiac remodeling in patients with acute coronary syndrome (ACS). Sixty-one patients with ACS complicated with RA (RA group) and 55 age- and sex-matched patients with ACS without RA (control group) were enrolled. We compared the parameters of laboratory and echocardiogram across the 2 groups. Levels of serum brain natriuretic peptide in patients with RA were significantly higher than control group. Prevalence of left ventricular hypertrophy (LVH), and LV diastolic dysfunction (E/A < 1) were significantly higher in the RA patients, while the LV ejection fraction (EF%) was significantly lower in RA patients. Incidence of tricuspid regurgitation and pulmonary regurgitation were significantly higher in ACS patients with RA than in the ACS patients without RA. In RA group, levels of serum high density lipoprotein cholesterol were negatively correlated with C reactive protein (CRP), EF% was also negatively correlated with CRP. The prevalence of LVH and mitral regurgitation showed positive correlations with ESR. Early intervention for controlling the inflammation associated with RA can play a significant role in preventing cardiac remodeling in ACS patients.

Rheumatoid arthritis: Recent advances on its etiology, role of cytokines and pharmacotherapy

An autoimmune disease is defined as a clinical syndrome resulted from an instigation of both T cell and B cell or individually, in the absence of any present infection or any sort of distinguishable cause. Clonal deletion of auto reactive cells remains the central canon of immunology for decades, keeping the role of T cell and B cell aside, which are actually the guards to recognize the entry of foreign body. According to NIH, 23.5 million Americans are all together affected by these diseases. They are rare, but with the exception of RA. Rheumatoid arthritis is chronic and systemic autoimmune response to the multiple joints with unknown ethology, progressive disability, systemic complications, early death and high socioeconomic costs. Its ancient disease with an old history found in North American tribes since 1500 BCE, but its etiology is yet to be explored. Current conventional and biological therapies used for RA are not fulfilling the need of the patients but give only partial responses. There is a lack of consistent and liable biomarkers of prognosis therapeutic response, and toxicity. Rheumatoid arthritis is characterized by hyperplasic synovium, production of cytokines, chemokines, autoantibodies like rheumatoid factor (RF) and anticitrullinated protein antibody (ACPA), osteoclastogensis, angiogenesis and systemic consequences like cardiovascular, pulmonary, psychological, and skeletal disorders. Cytokines, a diverse group of polypeptides, play critical role in the pathogenesis of RA. Their involvement in autoimmune diseases is a rapidly growing area of biological and clinical research. Among the proinflammatory cytokines, IL-1α/β and TNF-α trigger the intracellular molecular signalling pathway responsible for the pathogenesis of RA that leads to the activation of mesenchymal cell, recruitment of innate and adaptive immune system cells, activation of synoviocytes which in term activates various mediators including tumour necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6) and interleukin-8 (IL-8), resulting in inflamed synovium, increase angiogenesis and decrease lymphangiogensis. Their current pharmacotherapy should focus on their three phases of progression i.e. prearthritis phase, transition phase and clinical phase. In this way we will be able to find a way to keep the balance between the pro and anti-inflammatory cytokines that is believe to be the dogma of pathogenesis of RA. For this we need to explore new agents, whether from synthetic or natural source to find the answers for unresolved etiology of autoimmune diseases and to provide a quality of life to the patients suffering from these diseases specifically RA.

Relationship between sleep disturbances and multimorbidity among community-dwelling men and women aged 65-93 years: results from the KORA Age Study

BACKGROUND/OBJECTIVE

Although the association of disturbed sleep with specific chronic conditions is well known, the relationship between sleep disturbances and multiple diseases is less clear. Therefore, the objectives of this study were to examine the independent relationships of various sleep disturbances with 1) multimorbidity (≥2 chronic conditions) and 2) commonly co-occurring pairs of chronic conditions.

METHODS

Analyses were based on data from 4127 individuals aged ≥65 years participating in the population-based cross-sectional Cooperative Health Research in the Region of Augsburg (KORA) Age Study conducted from 2008 to 2009 in Germany. Sex-specific odds ratios (OR) and 95% confidence intervals (CI) were calculated from sequential logistic regression models.

RESULTS

Neither short nor long daily sleep duration was significantly associated with multimorbidity among men; a significant positive relationship was identified regarding short sleep duration among women (OR 2.16, 95% CI: 1.42-3.30). While insomnia and all unique symptoms of insomnia were connected to multimorbidity among women in the multivariable models, the relationship concerning trouble falling asleep no longer remained significant after adjustment for all covariables among men. Regarding commonly co-occurring pairs of conditions, the clearest associations were observed between insomnia and daytime tiredness with joint diseases/eye diseases in men and joint diseases/heart diseases in women.

CONCLUSIONS

There seems to be sex-specific particularities in the relationship between sleep disturbances and sleep duration with multimorbidity and commonly co-occurring pairs of chronic conditions in older adults from the general population.

Prevention of Stroke in Rheumatoid Arthritis

The risk of cerebrovascular disease is increased among rheumatoid arthritis (RA) patients and remains an underserved area of medical need. Only a minor proportion of RA patients achieve suitable stroke prevention. Classical cardiovascular risk factors appear to be under-diagnosed and undertreated among patients with RA. Reducing the inflammatory burden is also necessary to lower the cardiovascular risk. An adequate control of disease activity and cerebrovascular risk assessment using national guidelines should be recommended for all patients with RA. For patients with a documented history of cerebrovascular or cardiovascular risk factors, smoking cessation and corticosteroids and non-steroidal anti-inflammatory drugs at the lowest dose possible are crucial. Risk score models should be adapted for patients with RA by introducing a 1.5 multiplication factor, and their results interpreted to appropriately direct clinical care. Statins, angiotensin-converting enzyme inhibitors, and angiotensin-II receptor blockers are preferred treatment options. Biologic and non-biologic disease-modifying anti-rheumatic drugs should be initiated early to mitigate the necessity of symptom control drugs and to achieve early alleviation of the inflammatory state. Early control can improve vascular compliance, decrease atherosclerosis, improve overall lipid and metabolic profiles, and reduce the incidence of heart disease that may lead to atrial fibrillation. In patients with significant cervical spine involvement, early intervention and improved disease control are necessary and may prevent further mechanical vascular injury.

Rheumatoid arthritis affects left ventricular mass: Systematic review and meta-analysis

BACKGROUND

Cardiovascular disease represents one of the most important extra-articular causes of morbidity and mortality in patients with rheumatoid arthritis (RA). Evidences showed that several cardiac structures can be affected during the course of the disease as well as abnormalities of left ventricular diastolic filling. Contrasting data are available about left ventricular mass (LVM) involvement in patients asymptomatic for cardiovascular disease. The purpose of this systematic review and meta-analysis is to summarize the effects of RA on LVM in rheumatoid arthritis patients without cardiovascular disease.

METHODS

A systematic research of the current case-control studies was conducted in Medline on November 20th, 2013. Studies were included if data of measurements of LVM were reported. The pooled mean effect size estimate was calculated according to methods described by Hedges and Olkin.

RESULTS

Sixteen eligible studies were included in this meta-analysis. RA determines an increase of absolute and indexed LVM compared with control patients [standardized mean difference (95% CI): 0.41(0.15-0.66) and 0.47(0.32-0.62), respectively]. On the contrary, posterior wall thickness did not show a significant RA effect. Finally, a significant positive effect of RA on interventricular wall thickness was found [standardized mean difference (95% CI): 0.39 (0.07-0.71)].

CONCLUSIONS

Results of this meta-analysis suggest that increased absolute and indexed LVM seem to be characteristic of RA patients with a fundamental clinical significance since they are related to an increased risk of cardiovascular morbidity and mortality. Our data suggest the use of LVM as surrogate end-point for clinical trials involving RA patients.
