Epidemiology of CVD in rheumatic disease, with a focus on RA and SLE

Bidirectional association between cardiovascular disease and hip fracture: a systematic review and meta-analysis

BACKGROUND

The aim of this study was to comprehensively analyze the bidirectional association between cardiovascular disease (CVD) and hip fracture (HF).

METHODS

We searched PubMed, EMBASE, Web of Sciences, Cochrane Library, ScienceDirect and China National Knowledge Infrastructure for relevant studies. The Newcastle-Ottawa scale was used to evaluate the risk of bias. We conducted random effects model for meta-analysis and subgroup analysis of different ethnic groups. Sensitivity analysis and publication bias of this study were also evaluated. This study followed the PRISMA and MOOSE guidelines for systematic reviews and meta-analyses.

RESULTS

This research included 18 cohort studies and case-control studies with a total sample of 1,854,441 individuals. The results showed ischemic heart disease might increase the risk of HF (OR = 1.41, 95%CI[1.05, 1.89], I2 = 96%). Stroke might be a risk factor for HF (OR = 2.23, 95%[1.18, 4.19], I2 = 97%), and HF might likewise be a risk factor for Stroke ( OR = 2.22, 95% CI [1.81, 2.71], I2 = 78%). Heart failure might increase the risk of HF (OR = 2.89, 95%CI [1.22, 6.85], I2 = 91%), and HF might increase the risk of heart failure (OR = 2.74, 95%CI [1.27, 5.89], I2 = 92%). Hypertension might increase the risk of HF (OR = 1.55, 95%CI[1.34, 1.8], I2 = 87%), and HF might increase the risk of hypertension (OR = 3.75, 95%CI[3.3, 4.26], I2 = 98%). Cerebrovascular disease (OR = 1.96, 95%CI[1.61, 2.4], I2 = 79%) and diseases of arteries, arterioles, and capillaries (OR = 1.58, 95%CI[1.49, 1.68], I2 = 0%) might increase the risk of HF. HF might increase the risk of myocardial infarction (OR = 2, 95%CI[1.17, 3.41], I2 = 97%) and CVD-related death (OR = 1.78, 95%CI[1.05, 3.02], I2 = 50%). Subgroup analyses showed that among Asians IHD might not raise the risk of HF (OR = 1.33, 95% CI [1.00, 1.78], I2 = 95%). In caucasians, IHD might also not raise HF risk (OR = 1.52, 95%CI [0.64, 4.56], I2 = 95%).

CONCLUSIONS

This study supports possible bidirectional associations between CVD and HF, but more mechanistic studies of CVD and HF were warranted. However, high heterogeneity and potential confounding by unmeasured variables warrant cautious interpretation.

Lupus nephritis as an independent risk factor for carotid atherosclerosis in patients with systemic lupus erythematosus

OBJECTIVE

Systemic lupus erythematosus (SLE) is associated with an elevated risk of atherosclerosis, with lupus nephritis (LN) representing a critical and potentially fatal target organ damage. This study aims to investigate the prevalence of LN in SLE patients, and its correlation with carotid atherosclerosis (CA).

METHODS

A total of 151 SLE patients (age, 50.9 ± 14.6 years, 87.4% women) were included in the study. The 2024 KDIGO guideline was used to assess the LN prevalence, and carotid artery ultrasound was performed to identify plaque and intima-media thickness (IMT). The correlation between LN and CA in SLE patients was evaluated, and logistic regression analysis was conducted to identify CA risk factors.

RESULTS

A total of 47.0% of SLE patients exhibited LN, and the prevalence of CA was 37.7%. Patients with LN exhibited a higher carotid plaque ratio (47.9% vs 28.7%, p = 0.015) and IMT values [1.0(0.7, 1.1) mm vs. 0.8(0.7, 1.0) mm, p < 0.010] compared to those without LN. The presence of LN (p = 0.002), male sex (p = 0.039), age (p < 0.001), and serum TC (total cholesterol) (p = 0.016) were independent risk factors for SLE patients with CA. LN and related renal parameters demonstrated a strong association with CA in patients with SLE.

CONCLUSION

The prevalence of LN was significantly correlated with CA in SLE patients, indicating that early identification of LN in SLE patients has a high risk of CA, which may facilitate targeted prevention and reduce cardiovascular morbidity. Key Points • Lupus nephritis (LN) was present in 47.0% of systemic lupus erythematosus (SLE) patients, and carotid atherosclerosis (CA) was prevalent in 37.7% of the study. • Systemic lupus erythematosus (SLE) patients with lupus nephritis (LN) exhibited significantly higher carotid plaque ratios and increased intima-media thickness compared to those without LN. • The presence of lupus nephritis (LN), male sex, advanced age, and elevated total cholesterol levels was identified as independent risk factors for carotid atherosclerosis (CA) in patients with systemic lupus erythematosus (SLE).

Anti-Inflammatory effect of INSL-3 on experimental arthritis model and LPS-induced macrophage cell line

Rheumatoid arthritis (RA) is a multifactorial autoimmune disease that affects the joints of approximately 1 % of the population worldwide and is seen 2-4 times less in males. INSL3 is a gender-specific peptide hormone produced much higher in males than in females and may have an anti-inflammatory role in RA. So, in this study, it was aimed to determine the possible anti-inflammatory effect and dose of insulin-like factor-3(INSL3) in an experimental Complete Freund's adjuvant(CFA)-induced RA male rat model and lipopolysaccharide(LPS)-induced macrophage cell line and compare it with prednisolone therapy. For in vivo experiments, 48 male mice were randomly divided into 6 groups with 8 subjects in each group: Control group, Arthritis group, Arthritis + Prednisolone(10 mg/kg) group, Arthritis + INSL3(0.08-0.8-8 μg/day) groups. Joint tissue samples obtained from sacrificed subjects were examined by histochemical and immunohistochemically methods after biometric analyses, arthritis severity scoring, and thermal latency experiments. LPS-induced macrophage cells were also treated with prednisolone(1 µg/ml) and INSL3(50-100-200 nM). Cell viability, cell morphology, and TNF-α and IL-6 immune reactivity were evaluated. According to the data obtained from in vivo analyses, it was seen that INSL3 reduced the paw diameter and arthritis severity scoring, degenerative changes, and inflammation and increased the thermal latency, compared to the arthritis group, although not as much as the prednisolone treatment group. In vitro analyses showed that high doses of INSL3 had positive effects on cell viability, morphology, TNF-α, and IL-6 immune reactivity. In conclusion, it was determined that the anti-inflammatory effect of INSL3 was not as pronounced as prednisolone, but it had a more favorable impact on macrophage cell viability and morphology. It was concluded that INSL3 may be a protective therapeutic agent in combination with existing treatment protocols in treating many autoimmune diseases.

Clinical characteristics and risk factors of cardiovascular disease in systemic lupus erythematosus patients

To analyze the clinical characteristics of cardiovascular disease in systemic lupus erythematosus (SLE) patients and identify risk factors for predicting the occurrence of cardiovascular disease in SLE patients. Clinical data of 110 SLE patients were randomly selected from the Tongde Hospital of Zhejiang Province clinical medical record database, including 50 patients with cardiovascular disease and 60 patients without. Clinical data, blood biochemistry indicators, antibody detection results, and complement levels were collected. The receiver operating characteristic (ROC) curve was used to analyze the efficacy of these differential indicators in predicting the occurrence of cardiovascular disease in SLE patients. Univariate logistic regression analysis and multivariate logistic regression analysis showed that anti-ribosomal P protein, RNP/sm, IgG, IgM, serum creatinine, uric acid, and lipoprotein a were independent risk factors for cardiovascular disease in SLE patients (P < 0.05). The area under the curve (AUC) for predicting cardiovascular disease in SLE patients using IgG was 0.67, with low sensitivity of 44% and high specificity of 88.48%. The AUC for predicting cardiovascular disease in SLE patients using IgM was 0.67, with sensitivity of 76% and specificity of 55.17%. The AUC for predicting cardiovascular disease in SLE patients using serum creatinine was 0.73, with sensitivity of 68% and specificity of 78.33%. The AUC for predicting cardiovascular disease in SLE patients using uric acid was 0.69, with sensitivity of 52% and specificity of 81.67%. The AUC for predicting cardiovascular disease in SLE patients using lipoprotein a was 0.96, with high sensitivity of 96% and specificity of 91.67%. Levels of anti-ribosomal P protein, RNP/sm, IgG, IgM, serum creatinine, uric acid, and lipoprotein A are significantly altered in SLE patients with cardiovascular disease. These indicators can be used to predict the risk of cardiovascular disease in SLE patients.

Exploration of Risk Factors for Cardiovascular Disease in Patients with Rheumatoid Arthritis: A Retrospective Study

OBJECTIVE

Patients with rheumatoid arthritis (RA) have increased mortality and morbidity rates owing to cardiovascular diseases (CVD). Timely detection of CVD in RA can greatly improve patient prognosis; however, this technique remains challenging. We aimed to investigate the risk factors for CVD incidence in patients with RA.

METHODS

This retrospective study included RA patients without CVD risk factors (n = 402), RA with CVD risk factors (n = 394), and RA with CVD (n = 201). Their data on routine examination indicators, vascular endothelial growth factor (VEGF), and immune cells were obtained from medical records. The characteristic variables between each group were screened using univariate analysis, least absolute shrinkage and selection operator (LASSO), random forest (RF), and logistic regression (LR) models, and individualized nomograms were further established to more conveniently observe the likelihood of CVD in RA.

RESULTS

Univariate analysis revealed significantly elevated levels of white blood cells (WBC), blood urea nitrogen (BUN), creatinine, creatine kinase (CK), lactate dehydrogenase (LDH), VEGF, serum total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), apolipoprotein B100 (ApoB100), and apolipoprotein E (ApoE) in RA patients with CVD, whereas apolipoprotein A1 (ApoA1) and high-density lipoprotein/cholesterol (HDL/TC) were decreased. Furthermore, the ratio of regulatory T (Treg) cells exhibiting excellent separation performance in RA patients with CVD was significantly lower than that in other groups, whereas the ratios of Th1/Th2/NK and Treg cells were significantly elevated. The LASSO, RF, and LR models were also used to identify the risk factors for CVD in patients with RA. Through the final selected indicators screened using the three machine learning models and univariate analysis, a convenient nomogram was established to observe the likelihood of CVD in patients with RA.

CONCLUSIONS

Serum lipids, lipoproteins, and reduction of Treg cells have been identified as risk factors for CVD in patients with RA. Three nomograms combining various risk factors were constructed to predict CVD occurring in patients with RA (RA with/without CVD risk factors).

Exploring Cardiovascular Risk Factors and Atherosclerosis in Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a chronic inflammatory disease mainly affecting the peripheral diarthrodial joints symmetrically and also presenting many extra-articular manifestations. Morbidity and mortality in RA patients are higher compared to the general population. Cardiovascular (CV) disease is one of the most common causes of death in these patients. Classical or traditional risk factors for atherosclerosis development occur more frequently in RA patients compared to those without this condition. Studies have showed that RA patients often present comorbidities such as hypertension, dyslipidemia, diabetes mellitus and obesity. However, the high incidence of CV events occurring in RA patients is not explained by the presence of traditional risk factors. Systemic inflammation, as it is expressed with the presence of proinflammatory cytokines and increased acute phase reactants, may contribute to the development of premature atherosclerosis in these patients. In this review, we explore the risk factors for CV disease, the generation of dyslipidemia, the lipid paradox and the role of systemic inflammation in the atherosclerotic process in RA. We discuss also the role of early therapeutic intervention that suppresses inflammation which may have beneficial effects on CV disease in RA patients.

Predicting the risk of cardiovascular and cerebrovascular event in systemic lupus erythematosus: a Chinese SLE treatment and research group study XXVI

OBJECTIVE

Patients with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular and cerebrovascular events (CCEs). Furthermore, CCE was a significant factor contributing to mortality in patients with SLE. However, no clinical model exists that can predict which patients are at high risk. The purpose of this study was to develop a practical model for predicting the risk of CCE in people with SLE.

METHODS

This study was based on the Chinese SLE Treatment and Research Group cohort. A total of 2399 patients, who had a follow-up period of over 3 years and were diagnosed with SLE for less than 1 year at the start of the study, were included. Cox proportional hazards regression and least absolute shrinkage and selection operator regression were used to establish the model. Internal validation was performed, and the predictive power of the model was evaluated.

RESULTS

During the follow-up period, 93 patients had CCEs. The prediction model included nine variables: male gender, smoking, hypertension, age of SLE onset >40, cutaneous involvement, arthritis, anti-β2GP1 antibody positivity, high-dose glucocorticoids and hydroxychloroquine usage. The model's C index was 0.801. Patients with a prognostic index over 0.544 were classified into the high-risk group.

CONCLUSION

We have developed a predictive model that uses clinical indicators to assess the probability of CCE in patients diagnosed with SLE. This model has the ability to precisely predict the risk of CCE in patients with SLE. We recommended using this model in the routine assessment of patients with SLE.

The role of comprehensive stress cardiac MRI in autoimmune rheumatic disease: A review

Cardiovascular disease is the leading cause of morbidity and mortality in patients with autoimmune rheumatic diseases. Much of this may be attributed to systemic inflammation resulting in coronary atherosclerosis and myocarditis. Cardiac magnetic resonance imaging is the gold standard for the evaluation of cardiac structure and function, including tissue characterization, which allows for detection of myocardial edema, inflammation, and fibrosis. Advances in parametric mapping and coronary flow reserve measurement techniques have the potential to change the diagnosis, risk stratification, and management of patients with autoimmune rheumatic diseases. We provide an overview of the current evidence and suggest potential future roles for the use of comprehensive cardiac magnetic resonance in patients with autoimmune rheumatic diseases in the field of cardio-rheumatology.

Crosstalk between Inflammation and Atherosclerosis in Rheumatoid Arthritis and Systemic Lupus Erythematosus: Is There a Common Basis?

Cardiovascular disease is the leading cause of morbidity and mortality in patients with rheumatoid arthritis and systemic lupus erythematosus. Traditional cardiovascular risk factors, although present in lupus and rheumatoid arthritis, do not explain such a high burden of early cardiovascular disease in the context of these systemic connective tissue diseases. Over the past few years, our understanding of the pathophysiology of atherosclerosis has changed from it being a lipid-centric to an inflammation-centric process. In this review, we examine the pathogenesis of atherosclerosis in systemic lupus erythematosus and rheumatoid arthritis, the two most common systemic connective tissue diseases, and consider them as emblematic models of the effect of chronic inflammation on the human body. We explore the roles of the inflammasome, cells of the innate and acquired immune system, neutrophils, macrophages, lymphocytes, chemokines and soluble pro-inflammatory cytokines in rheumatoid arthritis and systemic lupus erythematosus, and the roles of certain autoantigens and autoantibodies, such as oxidized low-density lipoprotein and beta2-glycoprotein, which may play a pathogenetic role in atherosclerosis progression.

Understanding the spectrum of cardiovascular risk in women - A primer for prevention

Cardiovascular disease (CVD) is the leading cause of death in women worldwide and the lifetime risk of CVD in women is similar to men. However, the pathophysiology of CVD varies between women and men necessitating a sex-specific understanding of cardiovascular (CV) risk. A belief that women have a lower CVD risk than men, and an underrepresentation in clinical research for many years has led to a paucity of evidence in the prevention and management of CVD in women. Many recent efforts have tried to bridge the gap. As a result, we now know that traditional risk factors impact CVD risk differently in women when compared with men. There are also numerous sex-specific and pregnancy related risk factors that modify the risk and can predict the future development of CVD in women. This is important as risk calculators, in general, tend to misclassify risk in young women with nontraditional CVD risk factors. To address this, guidelines have introduced the concept of risk enhancers that can suggest a higher risk. The use of coronary artery calcium score can further accurately delineate risk in these women, leading to an appropriate matching of therapy to underlying risk. This review discusses implementation strategies that are essential to mitigate disparities in CVD outcomes and optimizing CVD risk in women.

Risk of Major Adverse Cardiovascular Events in Immune-Mediated Inflammatory Disorders on Biologics and Small Molecules: Network Meta-Analysis

BACKGROUND AND AIMS

Recent studies raise concern for increased risk of major adverse cardiovascular events (MACE) with Janus kinase (JAK) inhibitors used to treat immune-mediated inflammatory disorders (IMIDs). We aimed to examine MACE risk with licensed biologics and small molecules used commonly between IMIDs: inflammatory bowel disease, rheumatoid arthritis, psoriasis/psoriatic arthritis, and ankylosing spondylitis.

METHODS

Data were obtained from systematic searches (from inception to May 31, 2022) in PubMed, Embase, Ovid Medline, Scopus, Cochrane Central, and ClinicalTrials.gov. Studies that assessed a predefined MACE (myocardial infarction, cerebrovascular accident, unstable angina, cardiovascular death, or heart failure) risk in those ≥18 years of age with IMIDs treated with anti-interleukin (IL)-23 antibodies, anti-IL-12/23, anti-tumor necrosis factor α antibodies (anti-TNF-α), or JAK inhibitors were included in a network meta-analysis using a random-effects model with pooled odds ratios (ORs) reported with 95% credible intervals (CrIs) by drug class and disease state.

RESULTS

Among 3528 studies identified, 40 (36 randomized controlled trials and 4 cohort studies) were included in the systematic review, comprising 126,961 patients with IMIDs. Based on network meta-analysis of randomized controlled trials, regardless of disease state, anti-TNF-α (OR, 2.49; 95% CrI, 1.14-5.62), JAK inhibitors (OR, 2.64; 95% CrI, 1.26-5.99), and anti-IL-12/23 (OR, 3.15; 95% CrI, 1.01-13.35) were associated with increased MACE risk compared with placebo. There was no significant difference in the magnitude of the MACE risk between classes or based on IMID type.

CONCLUSIONS

Anti-IL-12/23, JAK inhibitors, and anti-TNF-α were associated with higher risk of MACE compared with placebo. The magnitude of the increased MACE risk was not different by IMID type. These results require confirmation in larger prospective studies.

Antimalarial Adherence and Risk of Cardiovascular Events in Patients With Rheumatoid Arthritis and Systemic Lupus Erythematosus: A Population-Based Study

OBJECTIVE

We aimed to assess the association between antimalarial adherence and cardiovascular events between incident rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) population-based cohorts.

METHODS

All patients with incident RA/SLE and incident antimalarial use in British Columbia, Canada, between January 1997 and March 2015 were identified using provincial administrative databases. The outcomes were incident cardiovascular events, including myocardial infarction (MI), stroke, or venous thromboembolism (VTE). The exposure was antimalarial adherence with levels: discontinuation (proportion of days covered [PDC = 0]), nonadherence (0 < PDC < 0.90), and adherence (PDC ≥ 0.90). We used marginal structural models to estimate the effect of antimalarial adherence on the rate of cardiovascular events, accounting for potential confounders.

RESULTS

We identified 16,538 individuals with incident RA/SLE and incident antimalarial use without any cardiovascular event before the index date. Over nine years mean follow-up, 2,174 incident cardiovascular events (13.2%) were observed. The adjusted hazard ratio (aHR) for incident cardiovascular events for antimalarial adherence relative to discontinuation was 0.72 (95% confidence interval [CI] 0.64-0.81) and 1.01 (95% CI 0.90-1.14) for nonadherence. Additionally, the aHRs for all cardiovascular events, MI, stroke, and VTE for adherence relative to nonadherence was 0.71 (95% CI 0.61-0.82), 0.62 (95% CI 0.51-0.75), 0.45 (95% CI 0.36-0.58), and 0.65 (95% CI 0.46-0.93), respectively. We found older age modified the association between antimalarial adherence and cardiovascular events (P = 0.02).

CONCLUSION

When people newly diagnosed with RA or SLE take their antimalarial regularly as prescribed (PDC ≥ 0.90), they have a 29% lower risk of sustaining a cardiovascular event than patients with a lower degree of adherence (PDC < 0.90) and a 28% lower risk than if they discontinue antimalarials.

Moderate and high disease activity levels increase the risk of subclinical atherosclerosis progression in early rheumatoid arthritis: a 5-year prospective study

OBJECTIVES

To elucidate the association between different disease activity levels over time on long-term vascular outcomes in patients with early rheumatoid arthritis (ERA).

METHODS

This was a 5-year prospective study. Patients with consecutive ERA without overt cardiovascular disease (CVD) were recruited to receive 1 year of tight-control treatment followed by standard-of-care management. High-resolution carotid ultrasound was assessed at baseline and year 5. The primary outcome was subclinical atherosclerosis progression (AP+), defined as the occurrence of incident plaque, increased region harbouring plaques and/or maximum carotid intima-media thickness progression ≥0.9 mm at year 5. Inflammatory burden during the follow-up period was represented by the cumulative average Disease Activity Score 28-erythrocyte sedimentation rate (ca-DAS28-ESR). Persistent low disease activity (LDA) or remission state was defined as ca-DAS28-ESR≤3.2.

RESULTS

One-hundred and four patients with ERA (age: 52±11 years, 81 (77.9%) female) were included in this analysis. Fifty-two (50%) patients achieved persistent LDA or remission and 42 patients (40.4%) had AP+. Patients in the AP+ group were older and had more traditional cardiovascular risk factors at baseline. Multivariate logistic regression analysis revealed that patients with persistent moderate or high disease activity (ca-DAS28-ESR>3.2) had a significantly increased risk of AP+ (OR 5.05, 95% CI 1.53, 16.64, p=0.008) compared with those who achieved persistent remission. The risk of AP+ was similar in patients who achieved persistent LDA and remission.

CONCLUSIONS

Achieving persistent LDA or remission may prevent progression of atherosclerosis in ERA. A treat-to-target approach aiming at sustained LDA or remission may reduce the risk of CVD by preventing AP+.

The NLRP3 Inflammasome as a Pathogenic Player Showing Therapeutic Potential in Rheumatoid Arthritis and Its Comorbidities: A Narrative Review

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease characterized by chronic synovitis and the progressive destruction of cartilage and bone. RA is commonly accompanied by extra-articular comorbidities. The pathogenesis of RA and its comorbidities is complex and not completely elucidated. The assembly of the NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome activates caspase-1, which induces the maturation of interleukin (IL)-1β and IL-18 and leads to the cleavage of gasdermin D with promoting pyroptosis. Accumulative evidence indicates the pathogenic role of NLRP3 inflammasome signaling in RA and its comorbidities, including atherosclerotic cardiovascular disease, osteoporosis, and interstitial lung diseases. Although the available therapeutic agents are effective for RA treatment, their high cost and increased infection rate are causes for concern. Recent evidence revealed the components of the NLRP3 inflammasome as potential therapeutic targets in RA and its comorbidities. In this review, we searched the MEDLINE database using the PubMed interface and reviewed English-language literature on the NLRP3 inflammasome in RA and its comorbidities from 2000 to 2023. The current evidence reveals that the NLRP3 inflammasome contributes to the pathogenesis of RA and its comorbidities. Consequently, the components of the NLRP3 inflammasome signaling pathway represent promising therapeutic targets, and ongoing research might lead to the development of new, effective treatments for RA and its comorbidities.

Exploring cardiovascular implications in systemic lupus erythematosus: A holistic analysis of complications, diagnostic criteria, and therapeutic modalities, encompassing pharmacological and adjuvant approaches

Systemic lupus erythematosus (SLE) poses a diagnostic challenge due to its heterogeneity. This study examines the cardiac complications of SLE comprehensively, covering pericarditis, myocarditis, pleural effusion, valvular disease, atherosclerosis, and cardiac arrhythmias. Nearly one-third of SLE-related deaths are attributed to cardiovascular diseases, necessitating a deeper understanding of cardiac pathophysiology. The impact of SLE on the cardiovascular system manifests in various ways, including recurrent and resistant pericarditis, severe myocarditis, and pleural effusion. Valvular diseases, atherosclerosis, and cardiac arrhythmias are prevalent, with immune complex deposition playing a role in atherosclerosis. Diagnostic criteria involve clinical features, laboratory findings, and autoantibodies, emphasizing the need for early diagnosis and a multidisciplinary diagnostic approach. The review explores pharmacological and non-pharmacological modalities for managing cardiac manifestations in SLE. Recommendations include NSAIDs, colchicine, and proton pump inhibitors for acute pericarditis, while selective immunosuppressive therapy is emerging for myocarditis. Valvular diseases require individualized treatment approaches, and careful corticosteroid management is crucial to avoid increased cardiovascular events. Anti-malarial therapy, particularly hydroxychloroquine, shows promise in mitigating cardiovascular risk factors. Non-pharmacological modifications, such as diet, exercise, and smoke cessation, significantly contribute to cardiovascular health in SLE patients. Adjuvant therapies involving glutathione and glutathione peroxidase focus on redox balance, offering potential interventions. This integrated approach combines diagnostic insights with diverse treatment modalities, providing a holistic strategy for managing cardiac complications in SLE. Ongoing research is essential to refine these strategies and optimize individualized treatment plans for improved patient outcomes.

The clinical characteristics, managements, and outcomes of acute myocardial infarction in osteoarthritis patients; a cross-sectional analysis of 6.5 million patients

OBJECTIVES

The prevalence of osteoarthritis (OA) and cardiovascular disease are increasing and both conditions share similar risk factors. We investigated the association between OA and receipt of invasive managements and clinical outcomes in patients with acute myocardial infarction (AMI).

METHODS

Using the National Inpatient Sample, adjusted binary logistic regression determined the association between OA and each outcome variable.

RESULTS

Of 6,561,940 AMI hospitalizations, 6.3% had OA. OA patients were older and more likely to be female. OA was associated with a decreased odds of coronary angiography (adjusted odds ratio 0.91; 95% confidence interval 0.90, 0.92), PCI (0.87; 0.87, 0.88), and coronary artery bypass grafting (0.98; 0.97, 1.00). OA was associated with a decreased odds of adverse outcomes (in-hospital mortality: 0.68; 0.67, 0.69; major acute cardiovascular and cerebrovascular events: 0.71; 0.70, 0.72; all-cause bleeding: 0.76; 0.74, 0.77; and stroke/TIA: 0.84; 0.82, 0.87).

CONCLUSIONS

This study of a representative sample of the US population highlights that OA patients are less likely to be offered invasive interventions following AMI. OA was also associated with better outcomes post-AMI, possibly attributed to a misclassification bias where unwell patients with OA were less likely to receive an OA code because codes for serious illness took precedence.

Causal relationship between rheumatoid arthritis and hypothyroidism or hyperthyroidism: a bidirectional two-sample univariable and multivariable Mendelian randomization study

Objective

The causal relationship between Rheumatoid arthritis (RA) and hypothyroidism/hyperthyroidism remains controversial due to the limitations of conventional observational research, such as confounding variables and reverse causality. We aimed to examine the potential causal relationship between RA and hypothyroidism/hyperthyroidism using Mendelian randomization (MR).

Method

We conducted a bidirectional two-sample univariable analysis to investigate the potential causal relationship between hypothyroidism/hyperthyroidism and RA. Furthermore, we performed a multivariate analysis to account for the impact of body mass index (BMI), smoking quantity, and alcohol intake frequency.

Results

The univariable analysis indicated that RA has a causative influence on hypothyroidism (odds ratio [OR]=1.07, 95% confidence interval [CI]=1.01-1.14, P=0.02) and hyperthyroidism (OR=1.32, 95% CI=1.15-1.52, P<0.001). When hypothyroidism/hyperthyroidism was considered as an exposure variable, we only observed a causal relationship between hypothyroidism (OR=1.21, 95% CI=1.05-1.40, P=0.01) and RA, whereas no such connection was found between hyperthyroidism (OR=0.91, 95% CI=0.83-1.01, P=0.07) and RA. In the multivariate MR analyses, after separately and jointly adjusting for the effects of daily smoking quantity, alcohol intake frequency, and BMI, the causal impact of RA on hypothyroidism/hyperthyroidism and hypothyroidism on RA remained robust. However, there is no evidence to suggest a causal effect of hyperthyroidism on the risk of RA (P >0.05).

Conclusion

Univariate and multivariate MR analyses have validated the causal association between RA and hypothyroidism/hyperthyroidism. Hypothyroidism confirmed a causal relationship with RA when employed as an exposure variable, whereas no such relationship was found between hyperthyroidism and RA.

Comparison of the cardiovascular risk profile of rheumatoid arthritis versus hand osteoarthritis patients

It is clear that there is an increased cardiovascular (CV) risk in rheumatoid arthritis (RA) as a result of systemic inflammation. Hand osteoarthritis (HOA) patients, also have an increased CV risk, but the causes are still debated. Our objective was to compare CV risk factors and risk scores between HOA and RA patients. Thirty-five HOA patients were matched by age (< 3 years) and sex to 35 RA patients in a case-control study. We compared their CV risk profiles and their risk of occurrence of CV events at 10 years using the risk equations SCORE1, SCORE2, and QRISK3. There was a significant increase in SCORE1, SCORE2, but not in QRISK3 in the RA group compared to the HOA group, provided that the multiplication coefficient for RA was applied. This increase was found to no longer be significant for SCORE1 when RA patients have low disease activity (DAS28 ≤ 3.2; n = 8). There was no difference between groups in the frequency of metabolic syndrome, blood pressure, abdominal circumference, body mass index, uricemia, triglyceridemia, HDL cholesterolemia, or pain intensity. Conversely, HOA patients had higher LDL cholesterol and fasting blood glucose levels, in the main analysis and in the subgroup of moderate/high RA activity patients (DAS28 > 3.2; n = 26). We found a higher CV risk in RA compared to HOA patients with moderate/high disease activity. The increased CV risk reported in OA remains to be confirmed in HOA, but these patients appear to have a pro-atherogenic lipid and glycemic profile.

Cardiovascular issues in rheumatic diseases

Cardiovascular disease is a major cause of morbidity and mortality in rheumatic diseases, particularly rheumatoid arthritis and systemic lupus erythematosus. Timely detection and monitoring of cardiovascular affections by advanced visualization techniques may improve outcomes across most rheumatic diseases. Although high-grade inflammation and (auto)immune pathways are well known for their negative effects on the heart and vasculature, cardiovascular risk estimation remains one of the unresolved critical issues in rheumatic diseases. The issue is complicated further in view of the latest reports on enhanced atherogenesis in the setting of fibromyalgia and osteoarthritis, where inflammation is seemingly not a major pathogenic factor. The intensity of systemic inflammation has been associated with major vascular events in some large cohort studies of inflammatory rheumatic diseases. Experts advocate for tight control of systemic inflammation and modifiable cardiovascular risk factors for reducing the overall risk of vascular events. Increasing patients' and specialists' knowledge and skills in cardiovascular monitoring and prevention is warranted to solve some of the cardiovascular issues in rheumatic diseases. Key Points • Cardiovascular issues are prevalent across all age groups of patients with rheumatic diseases. • Large cohort studies suggest that the intensity of systemic inflammation is a powerful predictor of vascular events in rheumatic diseases. • Reliable and widely tested tools for predicting vascular events in inflammatory rheumatic diseases are currently unavailable. • Empowering patients with rheumatic diseases and first-contact specialists with knowledge and skills to monitor and reduce cardiovascular risk factors' effects is a promising strategy.

Cardiac magnetic resonance assessment of cardiac involvement in autoimmune diseases

Cardiac magnetic resonance (CMR) is emerging as the modality of choice to assess early cardiovascular involvement in patients with autoimmune rheumatic diseases (ARDs) that often has a silent presentation and may lead to changes in management. Besides being reproducible and accurate for functional and volumetric assessment, the strength of CMR is its unique ability to perform myocardial tissue characterization that allows the identification of inflammation, edema, and fibrosis. Several CMR biomarkers may provide prognostic information on the severity and progression of cardiovascular involvement in patients with ARDs. In addition, CMR may add value in assessing treatment response and identification of cardiotoxicity related to therapy with immunomodulators that are commonly used to treat these conditions. In this review, we aim to discuss the following objectives: •Illustrate imaging findings of multi-parametric CMR approach in the diagnosis of cardiovascular involvement in various ARDs;•Review the CMR signatures for risk stratification, prognostication, and guiding treatment strategies in ARDs;•Describe the utility of routine and advanced CMR sequences in identifying cardiotoxicity related to immunomodulators and disease-modifying agents in ARDs;•Discuss the limitations of CMR, recent advances, current research gaps, and potential future developments in the field.

Effect of the JAK/STAT Inhibitor Tofacitinib on Macrophage Cholesterol Metabolism

The impact of JAK/STAT inhibitors, which are used in various inflammatory diseases, on cardiovascular risk is controversial and has recently raised safety concerns. Our study investigates the direct effects of tofacitinib on macrophage cholesterol metabolism, which is crucial for atherosclerosis plaque development and stability. Cultured human macrophages THP-1 were used to assess the impact of tofacitinib on cell cholesterol efflux and synthesis via radioisotopic methods, and on cholesterol uptake by measuring the cell cholesterol content with a fluorometric assay. The cholesterol acceptors and donors were either standard lipoproteins or sera from patients with juvenile idiopathic arthritis (JIA) and from control subjects. Tofacitinib significantly increased the macrophage cholesterol efflux to all acceptors; it reduced cholesterol uptake from both the normal and hypercholesterolemic sera; and it reduced cholesterol synthesis. The treatment of macrophages with tofacitinib was able to increase the cholesterol efflux and decrease cholesterol uptake when using sera from untreated JIA patients with active disease as cholesterol acceptors and donors, respectively. In conclusion, our in vitro data support the concept that tofacitinib has a favorable impact on macrophage cholesterol metabolism, even in the presence of sera from rheumatologic patients, and suggest that other mechanisms may be responsible for the cardiovascular risk associated with tofacitinib use in selected patient populations.

Humoral responses against HDL are linked to lipoprotein traits, atherosclerosis, inflammation and pathogenic pathways during early arthritis stages

OBJECTIVE

Chronic inflammation and immune dysregulation are crucial mechanisms for atherosclerosis in RA. Recent evidence suggests a link via humoral responses against high-density lipoproteins (HDL). This study aimed to characterize the specificity, clinical relevance and emergence of humoral responses against HDL along disease course, especially during the earliest phases of arthritis.

METHODS

IgG and IgM serum levels of antibodies against HDL (anti-HDL) and apolipoprotein A1 (anti-ApoA1) were measured in 82 early RA patients, 14 arthralgia individuals and 96 controls. Established RA patients (n = 42) were included for validation. Atherosclerosis and vascular stiffness were measured by Doppler ultrasound. Lipoprotein content, particle numbers and size were measured by H-NMR. Cytokines were measured by immunoassays. A cardiometabolic-related protein panel was evaluated using high-throughput targeted proteomics.

RESULTS

Anti-HDL and anti-ApoA1 responses were increased in early RA compared with controls (both P < 0.001) and were comparable to established disease. Only anti-ApoA1 antibodies were increased in arthralgia. IgG anti-HDL and anti-ApoA1 were associated with unfavourable lipoprotein traits in RA and arthralgia, respectively. A similar picture was observed for inflammatory mediators. No associations with clinical features or risk factors were found. IgG anti-HDL were independently associated with atherosclerosis occurrence in early RA, and outperformed patient stratification over conventional algorithms (mSCORE) and their anti-ApoA1 counterparts. Anti-HDL antibodies correlated with proteins involved in immune activation, remodelling and lipid metabolism pathways in early RA.

CONCLUSION

Humoral responses against HDL particles are an early event along the arthritis course, although quantitative and qualitative differences can be noticed among stages. These differences informed distinct capacities as biomarkers and underlying pathogenic circuits.

Metabolic Syndrome and Its Components Have a Different Presentation and Impact as Cardiovascular Risk Factors in Psoriatic and Rheumatoid Arthritis

Patients with chronic inflammatory arthritis have a higher cardiovascular (CV) risk than the general population. Traditional CV risk factors are clearly implicated, while the impact of metabolic syndrome (MetS) is less defined. The aim of this study was to compare MetS prevalence and impact on the CV risk in psoriatic arthritis (PsA) versus rheumatoid arthritis (RA). A retrospective analysis of real-world data of PsA and RA patients referred to a rheumatology clinic was conducted. The following data were extracted and compared: demographic data; clinical data; presence of traditional CV risk factors and MetS. Univariate and multivariate models were used to compare the impact of MetS and its components in patients with PsA versus RA. Overall, 170 patients were included (PsA: 78; RA; 92). The two groups differed significantly in mean age, disease duration, and presence of MetS, while other variables were comparable. Univariate and multivariate analysis identified distinct predictors of MetS in PsA (hypertension) and RA (dyslipidemia). The history of CV events was similar in the two groups. Predictors of CV events were MetS and most of its components in PsA, while dyslipidemia was the strongest predictor in RA. These associations were stronger in PsA than in RA. In conclusion, the impact of MetS and its components is different in PsA and RA. The association of these risk factors with CV events is stronger in PsA than in RA. This suggests the implication of different mechanisms, which may require distinct strategies for the prevention of CV events in PsA and RA.

Liquiritigenin Attenuated Collagen-Induced Arthritis and Cardiac Complication <i>via</i> Inflammation and Fibrosis Inhibition in Mice

Rheumatoid arthritis (RA) is a common autoimmune disease with increased cardiovascular disease risk. Liquiritigenin (LG) is a triterpene with anti-inflammatory properties. Our study aimed to explore the effect of LG on RA and the cardiac complication. Collagen-induced arthritis (CIA) mice with LG treatment exhibited obvious alleviation in histopathological changes, accompanied by the decreased expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-17A in synovium and serum. LG attenuated cartilage destruction by reducing matrix metalloproteinase (MMP)-3 and MMP-13 expression in the synovium of CIA mice. The echocardiography results proved the alleviation of cardiac dysfunction in CIA mice. The electrocardiogram, biochemical, and histochemical analysis proved the cardioprotection effect of LG against RA. The decreased expression of inflammatory factors (TNF-α, IL-1β, and IL-6) and fibrotic markers (fibronectin, Collagen I, and Collagen III) in cardiac tissues of CIA mice further corroborated the attenuation of myocardial inflammation and fibrosis by LG. Mechanistic studies showed that LG could inhibit transforming growth factor β-1 (TGF-β1) and phos-Smad2/3 expression in cardiac tissues of CIA mice. Our study suggested that LG could relieve RA and its cardiac complication probably by inhibiting the TGF-β1/Smad2/3 pathway. All these suggested that LG might be a potential candidate for RA and its cardiac complication therapy.

Chronic rheumatologic disorders and cardiovascular disease risk in women

Cardiovascular disease (CVD) is a major health threat to women worldwide. In addition to traditional CVD risk factors, autoimmune conditions are increasingly being recognized as contributors to adverse CVD consequences in women. Chronic systemic autoimmune and inflammatory disorders can trigger premature and accelerated atherosclerosis, microvascular dysfunction, and thrombosis. The presence of comorbid conditions, duration of the autoimmune condition, disease severity, and treatment of underlying inflammation are all factors that impact CVD risk and progression. Early identification and screening of CVD risk factors in those with underlying autoimmune conditions may attenuate CVD in this population. Treatment with non-steroidal anti-inflammatory drugs, corticosteroids, disease modifying agents and biologics may influence CVD risk factors and overall risk. Multi-disciplinary and team-based care, clinical trials, and collaborative team-science studies focusing on systemic autoimmune conditions will be beneficial to advance care for women.

Retrospective cohort study of thromboembolic events in systemic lupus erythematosus with or without secondary antiphospholipid syndrome and their correlation to lupus activity and dyslipidemia

Background

Antiphospholipid syndrome (APS) is one of the most frequent forms of acquired thrombophilia and is associated with an increased risk of stroke, heart attack, pulmonary embolism, and miscarriage in young women. Thirty to 40% of systemic lupus erythematosus (SLE) patients have associated APS. Patients with SLE often have abnormal plasma lipid concentrations. The study aimed to assess the prevalence of thromboembolic insults in SLE patients, with or without APS, and its correlation with disease activity and dyslipidemia. This study included one hundred three patients, seventy-five of whom had SLE without associated APS and twenty-eight had SLE associated with APS.

Results

Vascular affection, neurological affection, and abortion were significantly higher in SLE patients associated with APS than SLE patients without APS (39.3% vs 6.7%, 46.4% vs 14.7%, 28.6% vs 5.3%, respectively; P < 0.001). Thromboembolic insults were present in 20% of SLE patients without APS, and those patients with thromboembolism demonstrated significantly higher SLEDAI (median = 15 vs 10, P < 0.001) and TG (median = 27.5 vs 18.2, P = 0.007), respectively, than other patients of the same group. The SLEDAI score was significantly higher in SLE patients associated with APS than in SLE patients without APS (P < 0.001). Serum cholesterol and low-density lipoprotein (LDL) were significantly higher in SLE patients associated with APS (93.8 ± 25.3 mg/dl) than in SLE patients without APS (82.3 ± 19.6 mg/dl, P = 0.018; 50 ± 15.9 mg/dl, P = 0.048, respectively).

Conclusions

SLE patients are at significantly high risk for accelerated atherosclerosis, thromboembolism, and pregnancy loss which is multifactorial. Active disease should be well controlled. Lupus patients should be screened for aPL antibodies, and positive cases must be treated according to international guidelines. All patients with SLE should undergo lipid profile screening, and any abnormalities should be managed promptly.

Arterial stiffness, endothelial dysfunction and impaired fibrinolysis are pathogenic mechanisms contributing to cardiovascular risk in ANCA-associated vasculitis

Cardiovascular disease is a complication of systemic inflammatory diseases including anti-neutrophil cytoplasm antibody-associated vasculitis (AAV). The mechanisms of cardiovascular morbidity in AAV are poorly understood, and risk-reduction strategies are lacking. Therefore, in a series of double-blind, randomized case-control forearm plethysmography and crossover systemic interventional studies, we examined arterial stiffness and endothelial function in patients with AAV in long-term disease remission and in matched healthy volunteers (32 each group). The primary outcome for the case-control study was the difference in endothelium-dependent vasodilation between health and AAV, and for the crossover study was the difference in pulse wave velocity (PWV) between treatment with placebo and selective endothelin-A receptor antagonism. Parallel in vitro studies of circulating monocytes and platelets explored mechanisms. Compared to healthy volunteers, patients with AAV had 30% reduced endothelium-dependent vasodilation and 50% reduced acute release of endothelial active tissue plasminogen activator (tPA), both significant in the case-control study. Patients with AAV had significantly increased arterial stiffness (PWV: 7.3 versus 6.4 m/s). Plasma endothelin-1 was two-fold higher in AAV and independently predicted PWV and tPA release. Compared to placebo, both selective endothelin-A and dual endothelin-A/B receptor blockade reduced PWV and increased tPA release in AAV in the crossover study. Mechanistically, patients with AAV had increased platelet activation, more platelet-monocyte aggregates, and altered monocyte endothelin receptor function, reflecting reduced endothelin-1 clearance. Patients with AAV in long-term remission have elevated cardiovascular risk and endothelin-1 contributes to this. Thus, our data support a role for endothelin-blockers to reduce cardiovascular risk by reducing arterial stiffness and increasing circulating tPA activity.

Gum Arabic protects the rat heart from ischemia/reperfusion injury through anti-inflammatory and antioxidant pathways

Gum Arabic (GA) is a plant exudate with antioxidant and anti-inflammatory effects. GA has shown promise in protection from and treatment of kidney failure, however, its role in the protection of the heart from ischemia and reperfusion (I/R) has not been investigated. This study investigated the antioxidant and anti-inflammatory effects of Gum Arabic (GA) in the protection of the heart against ischemia/reperfusion (I/R) injury. Langendorff-perfused Wistar rat hearts were divided into seven groups. One group which was subjected to I/R with no other treatment served as the control group. The second group was subjected to buffer perfusion with no ischemia (sham group). The third group was perfused with GA in the absence of ischemia (sham + GA). The rest of the hearts were isolated from rats that had been treated with GA for 4 or 2 weeks in the drinking water, or GA that had been infused intravenously 2 h before sacrifice or added to perfusion buffer at reperfusion. Hemodynamics data were digitally computed; infarct size was measured using 2,3,5-triphenyltetrazolium chloride (TTC) staining and cardiomyocyte injury was assessed by quantifying creatine kinase (CK) and lactate dehydrogenase (LDH) enzymes. The total oxidants (TOS) and antioxidants (TAS), superoxide dismutase (SOD) and pro- and anti-inflammatory cytokines levels were estimated by ELISA. GA treatment for 2 weeks, 4 weeks or 2 hours before sacrifice resulted in a significant (P < 0.05) improvement in cardiac hemodynamics and reduction in infarct size and cardiac enzyme levels compared to respective controls. However, GA administration at the time of reperfusion did not protect the hearts against I/R injury. Furthermore, GA treatment decreased the pro-inflammatory and anti-inflammatory cytokines levels. The levels of TOS in the effluent were significantly decreased (P < 0.05) and SOD levels were significantly (P < 0.05) increased by GA administration. GA protected the heart against I/R injury when administered for 2 or 4 weeks or when infused 2 hours before sacrifice. GA treatment decreased the total oxidants levels, the pro-inflammatory cytokines TNF-α, IL-1β and IL-6 protein levels and increases SOD and anti-inflammatory cytokine IL-10 protein levels.

The influence of inflammation on cardiovascular disease in women

The onset of cardiovascular disease in women is almost a decade later than men, partly due to the protective effect of estrogen prior to menopause. Recently, it was noted that while there have been advances in improving the morbidity and mortality from CVD in women older than 55 years, the improvement in younger women has been stagnant. The mechanism behind this lag is unclear. This manuscript reviews the literature available on the sex-specific inflammatory response in the context of traditional and non-traditional cardiovascular disease risk factors. Our review suggests that women have a differential inflammatory response to various disease states that increases their risk for CVD and warrants a distinct prioritization from men when calculating cardiovascular disease risk.

Spontaneous coronary artery dissection and atherosclerosis in a young man with systemic lupus erythematosus: A case report and literature review

Background

Spontaneous coronary artery dissection (SCAD) is a rare coronary artery disease that frequently occurs in young, female patients without risk factors, and conservative treatment is often recommended for its management. The patient reported here is a male patient with systemic lupus erythematosus (SLE).

Case summary

We described a 28-year-old man with SLE who presented with acute ST-segment elevation myocardial infarction (STEMI), and was diagnosed with SCAD through a long dissection of the left anterior descending branch (LAD) by coronary angiography. The patient was treated with percutaneous coronary intervention (PCI) with stent implantation. Ten years later, he developed in-stent stenosis and other coronary atherosclerosis and was retreated with PCIs. Based on this case and according to the literature review, the existing treatment and prognosis of SLE with spontaneous coronary artery dissection and atherosclerosis are discussed.

Conclusion

Cardiovascular complications should be considered in patients with systemic lupus erythematosus, although they may not initially be atherosclerotic diseases. Attention should be paid to distinguish spontaneous coronary dissection in order to minimize missed or delayed diagnoses and take appropriate managements, as well as the development of atherosclerosis in SLE patients, and timely intervention has a better prognosis.

Cardiovascular Complications in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is an auto-immune disease of a relapsing-remitting nature that can cause multiorgan damage depending on several factors, mainly the disease activity. Young age women are the most likely to be affected by the disease and the female-to-male prevalence ratio is approximately 1:10. As the number of SLE patients has been increasing in the last few decades, the annual number of deaths due to the disease and its complications has increased as well, and one of the most important systems to which high mortality is attributed is the cardiovascular system, leading to premature atherosclerosis and other events such as endocarditis and valve disease. In addition to the classical cardiovascular risk factors, studies have found a positive correlation between SLE and other cardio-harmful diseases such as metabolic syndrome and dyslipidemia. Moreover, some of the medications used in the treatment of SLE place a heavy burden on the heart. The article reviews the shared pathophysiology of SLE and cardiovascular disease along with the most common SLE- associated cardiac risks, events, and management.

Systemic Lupus Erythematosus and Cardiovascular Disease: A Mendelian Randomization Study

Background

Previous studies have shown that patients with systemic lupus erythematosus (SLE) tend to have a higher risk of cardiovascular disease (CVD), but the potential causal relationship between genetic susceptibility to SLE and CVD risk is not clear. This study systematically investigated the potential association between genetically determined SLE and the risk of CVD.

Methods

The genetic tools were obtained from genome-wide association studies of SLE and CVD, with no overlap between their participating populations. Mendelian randomization (MR) analysis was performed using inverse variance weighting as the primary method. Simultaneously, a series of repeated analyses, sensitivity analyses, and instrumental variable strength evaluations were performed to verify the reliability of our results.

Results

MR analysis showed that genetic susceptibility to SLE was associated with a higher risk of heart failure (OR=1.025, 95% CI [1.009-1.041], P=0.002), ischemic stroke (OR=1.020, 95% CI [1.005-1.034], P=0.009), and venous thromboembolism (OR=1.001, 95% CI [1.000-1.002], P=0.014). However, genetic susceptibility to SLE was negatively correlated with the risk of type 2 diabetes (OR=0.968, 95% CI [0.947-0.990], P=0.004). Sensitivity analysis found no evidence of horizontal pleiotropy or heterogeneity.

Conclusion

Our MR study explored the causal role of SLE in the etiology of CVD, which would help improve our understanding of the basic disease mechanisms of SLE and provide comprehensive CVD assessment and treatment for SLE patients.

Different systemic rheumatic diseases as risk factors for COVID-19-related mortality

COVID-19 has been associated with increased morbidity and mortality, globally. Whether COVID-19-related mortality is increased in patients with systemic rheumatic diseases (SRDs) is still debatable. Although results are somewhat conflicting, there are a handful of nationwide studies published indicating that, in individuals with SRD, there is signal for increased adverse COVID-19-related outcomes and higher mortality. It appears that there are differences in COVID-19-related mortality across various SRDs. Besides, certain disease-specific (disease activity, disease duration, medication received) and/or other features (e.g. comorbidities) seem to also affect COVID-19-related mortality in SRD patients. Herein, we wanted to highlight that a more individualized approach taking into consideration the effect of the aforementioned factors into the risk calculation for COVID-19 adverse outcomes, including mortality, in SRD patients is warranted. A multinational study based on nationwide data, examining all common SRDs and stratifying accordingly, would be of interest, toward this direction. Key Points • It is still debatable whether Covid-19-related mortality is increased in patients with sytemic rheumatic diseases (SRD). • Disease-specific risk factors (e.g. type of SRD, disease activity) should be taken into account in risk assessment for Covid-19-releted outcomes in SRD patients.

Impaired left ventricular systolic synchrony in patients with lupus Nephritis: A speckle tracking echocardiography study

OBJECTIVES

We aimed to explore the value of two-dimensional speckle tracking echocardiography measurements of the global longitudinal strain (GLS) and left ventricular mechanical dispersion (LVMD) in the assessment of early stage left ventricular systolic dysfunction and heterogeneity of myocardial contraction in patients with lupus nephritis (LN).

METHODS

Patients with LN and extra-renal systemic lupus erythematosus (SLE) and healthy participants in the control group underwent echocardiography for the traditional measurement of the left ventricular systolic and diastolic function and speckle tracking measurements of the GLS and LVMD. GLS was defined as the average value of the peak strain during systole of the left ventricular 17 segments, and LVMD was defined as the standard deviation. The demographic characteristics including age, sex, and body mass index (BMI) of all the participants were collected. The clinical and laboratory characteristics of the patients with LN were collected.

RESULTS

We included 41 healthy control, 37 patients with extra-renal SLE, and 73 patients with LN. There were statistically significant differences in the GLS and LVMD between the extra-renal SLE and LN groups (GLS -19.36% vs. -17.61%, p < 0.001; LVMD 35.62 ms vs 42.96 ms, p<0.001). There was a statistically significant difference in the LVMD between the extral-renal SLE and control groups (35.62ms vs 25.51ms, p<0.001), but not in GLS (-19.36% vs -19.52%, p > 0.05). Multiple regression analyses were conducted in a subset of patients, and 24-hour proteinuria was independently associated with LVMD (β [SE], 0.793 [0.302], p < .05).

CONCLUSIONS

Patients with LN have more severe myocardial involvement than patients with extra-renal SLE. The asynchrony in myocardial contraction represented by the LVMD can be recognized earlier than that of the overall contractile functional impairment represented by GLS. In patients with LN, the 24-hour proteinuria was associated with LVMD. This indicates that the heterogeneity in the contractile function may be associated with the severity of renal damage.

Qinghao-Biejia Herb Pair Alleviates Pristane-Induced Lupus-Like Disease and Associated Renal and Aortic Lesions in ApoE−/− Mice

Backgroud: Systemic lupus erythematosus (SLE) is a chronic autoimmune disease involving multiple systems with a high prevalence of nephritis and atherosclerosis. Jieduquyuziyin prescription is a famous prescription with immune modulating and inflammation controlling effects, which is efficacious in the treatment of SLE. The most critical herbs in this prescription are Qinghao and Biejia. The aim of this study was to evaluate the therapeutic effect of Qinghao-Biejia herb hair (QB) on mice with SLE combined with atherosclerosis.

Materials and Methods: The effect of QB (identification using UPLC-TOF-MS) was assessed in female ApoE−/− mice intraperitoneally injected with 0.5 ml of pristane. Serum autoantibodies and lipid metabolic parameters were tested every 4 weeks, and spleen index, serum inflammatory biomarkers, renal injury, and aortic injury were observed after 16 weeks. The expression of signaling pathway in kidney tissues was observed by RT-qPCR and Western blot.

Results: The mice of QB-treated group exhibited a significant reduced serum autoantibodies level, urine protein, and renal immune complex deposition. QB treatment reduced the levels of inflammatory cytokines and improved the renal pathological changes. In addition, there was a reduction in aortic atheromatous plaque and some improvement in dyslipidemia. Moreover, QB suppressed the expression of HMGB1, TLR4, and MyD88 to some extent.

Conclusion: The present study implied that QB has clear efficacy for the treatment of SLE combined with atherosclerosis, and that inhibition of the HMGB1/TLR4 signaling pathway may be one of the therapeutic targets of QB for SLE combined with atherosclerosis.

The role of cardiovascular magnetic resonance in the evaluation of acute myocarditis and inflammatory cardiomyopathies in clinical practice - a comprehensive review

Inflammatory cardiomyopathy (I-CMP) is defined as myocarditis in association with cardiac dysfunction and/or ventricular remodelling. It is characterized by inflammatory cell infiltration into the myocardium and has heterogeneous infectious and non-infectious aetiologies. A complex interplay of genetic, autoimmune, and environmental factors contributes to the substantial risk of deteriorating cardiac function, acute heart failure, and arrhythmia as well as chronic dilated cardiomyopathy and its sequelae. Multi-parametric cardiovascular magnetic resonance (CMR) imaging is sensitive to many tissue changes that occur during myocardial inflammation, regardless of its aetiology. In this review, we summarize the various aetiologies of I-CMP and illustrate how CMR contributes to non-invasive diagnosis.

The association between rheumatoid arthritis and cardiovascular disease among adults in the United States during 1999-2018, and age-related effect modification in relative and absolute scales

PURPOSE

To explore the rheumatoid arthritis (RA)-cardiovascular diseases (CVD) association in relative and absolute risk scales among US adults aged ≥20 years over time and the effect modification of the association by age.

METHODS

We analyzed aggregated data from all ten continuous National Health and Nutrition Examination Survey cycles. A sample of 43,184 complete-case subjects was considered. The design-based regressions were used to investigate the associations in relative and absolute scales.

RESULTS

In relative scale, the CVD odds ratio was 2.32, 2.19, and 1.97 among adults with RA than no arthritis in 1999-2006, 2007-2012, and 2013-2018 cycles, respectively. This time trend was not statistically significant. The absolute risk estimates were 11, 10, and 9 per 100 CVD events. We also observed a significant effect modification by age; the higher relative risk among younger adults (<50 years) with RA and higher absolute risk in older adults (≥80 years) with RA were consistent across survey cycles.

CONCLUSIONS

There is a significant association between RA and CVD among US adults in both relative and absolute risks. Moreover, age is a significant effect modifier for this association; but with opposing age-related trends in relative and absolute scales.

Cardiovascular Manifestations, Imaging, and Outcomes in Systemic Lupus Erythematosus: An Eight-Year Single Center Experience in the United States

Systemic lupus erythematosus (SLE) is a challenging autoimmune and multi-system condition. With advances in cardiovascular screening and therapies for SLE patients, we evaluated the cardiovascular characteristics, multi-modality imaging, and outcomes of SLE at our tertiary referral center over an 8 year period. Consecutive patients from our SLE registry from April 2012 to March 2020 were retrospectively analyzed. Data pertaining to cardiovascular manifestations, investigations, management, and outcomes were assessed. We studied 258 SLE patients (mean age 42.2 ± 14.7 years); 233 (90.3%) were female. The main cardiac manifestations at index SLE clinic were pericardial disease in 33.3%, valve disease in 18%, cardiomyopathy in 9.6%, and stroke in 7.4%. During a mean follow-up of 3.0 ± 2.2 years after index SLE clinic, there were 5 (1.9%) deaths, 24 (9.3%) cardiovascular events, and 44 (17.1%) SLE-related hospitalizations. A history of stroke and hypertension were independently associated with cardiovascular events, hazard ratio (HR) (95% confidence intervals (CI)) of 5.38 (1.41-20.6) and 3.31 (1.02-10.7), respectively, while younger age and lower albumin predicted SLE-related hospitalizations. Cardiovascular manifestations are prevalent in SLE, especially for pericardial, valvular, and atherosclerotic diseases. With contemporary SLE and cardiovascular management, subsequent adverse cardiovascular events were infrequent in this study.

Identifying and managing psoriasis-associated comorbidities: the IMPACT research programme

Background

Psoriasis is a common, lifelong inflammatory skin disease, the severity of which can range from limited disease involving a small body surface area to extensive skin involvement. It is associated with high levels of physical and psychosocial disability and a range of comorbidities, including cardiovascular disease, and it is currently incurable.

Objectives

To (1) confirm which patients with psoriasis are at highest risk of developing additional long-term conditions and identify service use and costs to patient, (2) apply knowledge about risk of comorbid disease to the development of targeted screening services to reduce risk of further disease, (3) learn how patients with psoriasis cope with their condition and about their views of service provision, (4) identify the barriers to provision of best care for patients with psoriasis and (5) develop patient self-management resources and staff training packages to improve the lives of people with psoriasis.

Design

Mixed methods including two systematic reviews, one population cohort study, one primary care screening study, one discrete choice study, four qualitative studies and three mixed-methodology studies.

Setting

Primary care, secondary care and online surveys.

Participants

People with psoriasis and health-care professionals who manage patients with psoriasis.

Results

Prevalence rates for psoriasis vary by geographical location. Incidence in the UK was estimated to be between 1.30% and 2.60%. Knowledge about the cost-effectiveness of therapies is limited because high-quality clinical comparisons of interventions have not been done or involve short-term follow-up. After adjusting for known cardiovascular risk factors, psoriasis (including severe forms) was not found to be an independent risk factor for major cardiovascular events; however, co-occurrence of inflammatory arthritis was a risk factor. Traditional risk factors were high in patients with psoriasis. Large numbers of patients with suboptimal management of known risk factors were found by screening patients in primary care. Risk information was seldom discussed with patients as part of screening consultations, meaning that a traditional screening approach may not be effective in reducing comorbidities associated with psoriasis. Gaps in training of health-care practitioners to manage psoriasis effectively were identified, including knowledge about risk factors for comorbidities and methods of facilitating behavioural change. Theory-based, high-design-quality patient materials broadened patient understanding of psoriasis and self-management. A 1-day training course based on motivational interviewing principles was effective in increasing practitioner knowledge and changing consultation styles. The primary economic analysis indicated a high level of uncertainty. Sensitivity analysis indicated some situations when the interventions may be cost-effective. The interventions need to be assessed for long-term (cost-)effectiveness.

Limitations

The duration of patient follow-up in the study of cardiovascular disease was relatively short; as a result, future studies with longer follow-up are recommended.

Conclusions

Recognition of the nature of the psoriasis and its impact, knowledge of best practice and guideline use are all limited in those most likely to provide care for the majority of patients. Patients and practitioners are likely to benefit from the provision of appropriate support and/or training that broadens understanding of psoriasis as a complex condition and incorporates support for appropriate health behaviour change. Both interventions were feasible and acceptable to patients and practitioners. Cost-effectiveness remains to be explored.

Future work

Patient support materials have been created for patients and NHS providers. A 1-day training programme with training materials for dermatologists, specialist nurses and primary care practitioners has been designed. Spin-off research projects include a national study of responses to psoriasis therapy and a global study of the prevalence and incidence of psoriasis. A new clinical service is being developed locally based on the key findings of the Identification and Management of Psoriasis Associated ComorbidiTy (IMPACT) programme.

This project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full in Programme Grants for Applied Research; Vol. 10, No. 3. See the NIHR Journals Library website for further project information.

Proportionate Cardiovascular Mortality in Chronic Inflammatory Disease in Adults in the United States From 1999 to 2019

BACKGROUND

Despite a rising prevalence of chronic inflammatory disease (CID), the recent trends in cardiovascular disease (CVD) mortality of patients with CID is scarce. In this study, we investigated patterns of CVD mortality in systemic lupus erythematosus (SLE), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA) compared with the general population.

METHODS

We used the 1999 to 2019 multiple causes of death files from the national center for health statistics to analyze patterns and trends of proportionate CVD mortality in CID compared with the general population.

RESULTS

We analyzed a total of 11,154 CVD deaths in IBD, 58,337 CVD deaths in RA, 6227 CVD deaths in SLE, and 17,826,871 CVD deaths in the general population. Between 1999 and 2019, we found that proportionate CVD mortality decreased significantly in the IBD group (25% to 16%), RA group (34% to 25%), and the general population (41% to 31%), but did not change for the SLE group (15% to 15%). Patients with SLE who died of CVD were approximately 10 years younger compared with CVD decedents with RA, IBD, or general population. The White population had higher proportionate CVD mortality than African American (IBD [19% vs 16%-18%] and SLE [14%-16% vs 12-14%], respectively).

CONCLUSIONS

This study identifies current trends in CVD mortality in the CID population and elucidates current demographics in CVD mortality in CID. Although proportionate CVD mortality decreased in the general population, and in patients with RA and IBD, there was no change among patients with SLE. Further studies are needed to elucidate these differences.

Cardiovascular Implications of Immune Disorders in Women

Immune responses differ between men and women, with women at higher risk of developing chronic autoimmune diseases and having more robust immune responses to many viruses, including HIV and hepatitis C virus. Although immune dysregulation plays a prominent role in chronic systemic inflammation, a key driver in the development of atherosclerotic cardiovascular disease (ASCVD), standard ASCVD risk prediction scores underestimate risk in populations with immune disorders, particularly women. This review focuses on the ASCVD implications of immune dysregulation due to disorders with varying global prevalence by sex: autoimmune disorders (female predominant), HIV (male-female equivalent), and hepatitis C virus (male predominant). Factors contributing to ASCVD in women with immune disorders, including traditional risk factors, dysregulated innate and adaptive immunity, sex hormones, and treatment modalities, are discussed. Finally, the need to develop new ASCVD risk stratification tools that incorporate variables specific to populations with chronic immune disorders, particularly in women, is emphasized.

Cardiovascular Risk Prediction Parameters for Better Management in Rheumatic Diseases

The early detection of cardiovascular disease (CVD) serves as a key element in preventive cardiology. The risk of developing CVD in patients with rheumatic disease is higher than that of the general population. Thus, the objective of this narrative review was to assess and describe updated risk-prediction parameters for CVD in patients suffering from rheumatic diseases, and, additionally, to evaluate therapeutic and risk management possibilities. The processes of recognizing CVD risk factors in rheumatic diseases, establishing diagnoses, and discovering CV risk assessments are currently displeasing in clinical practice; they have a limited clinical impact. A large number of references were found while screening PUBMED, Scopus, and Google scholar databases; the 47 most relevant references were utilized to build up this study. The selection was limited to English language full text articles, RCTs, and reviews published between 2011 and 2021. Multiple imaging techniques, such as ECG, ultrasound, and cIMT, as well as biomarkers like osteoprotegerin cytokine receptor and angiopoietin-2, can be beneficial in both CV risk prediction and in early subclinical diagnosis. Physical exercise is an essential non-pharmacological intervention that can maintain the health of the cardiovascular system and, additionally, influence the underlying disease. Lipid-lowering drugs (methotrexate from the non-biologic DMARDs family as well as biologic DMARDs such as anti-TNF) were all associated with a lower CV risk; however, anti-TNF medication can decrease cardiac compliance and promote heart failure in patients with previously diagnosed chronic HF. Although they achieved success rates in reducing inflammation, glucocorticoids, NSAIDs, and COX-2 inhibitors were correlated with an increased risk of CVD. When taking all of the aforementioned points into consideration, there appears to be a dire need to establish and implement CVD risk stratification models in rheumatic patients.

Prevalence of Findings in Routine Abdominal Ultrasound in Patients with Systemic Autoimmune Rheumatic Diseases and Their Impact on Therapeutic Decision Making

Patients with systemic autoimmune rheumatic diseases (SARD) often receive abdominal ultrasound examinations to screen for organ involvement; yet, the spectrum of findings and their clinical relevance are poorly understood. We conducted a retrospective chart review of inpatients from a rheumatological referral centre with an abdominal ultrasound between 1 January2006 and 31 December 2015, examining 1092 SARD patients with a total of 1695 inpatient stays. The mean age was 55.1 years (range: 17–90 years, SD: 15.8), and the mean disease duration was 6.4 years (range: 0.0–52.8 years, SD: 9.1). A total of 87.5% of the patients were female. The most frequent ultrasound findings were hepatic steatosis (in 26.8% of all patients), splenomegaly (15.2% of all patients), pancreatic lipomatosis (14.3% of all patients) and aortic sclerosis (13.9% of all patients). Based on glucocorticoid and disease-modifying antirheumatic drug use, we identified cases where immuno-modulatory medication was escalated; there was an association between therapy escalation and the findings of hepatomegaly and pleural effusion (as tested via Fisher’s exact test). In patients with several examinations during the defined time span (n = 318), we found ultrasound findings to change, especially findings of hepatomegaly, pleural effusion and splenomegaly. When justifying decisions regarding the further treatment of a patient in the discharge letter, abdominal ultrasound results were rarely discussed. Abdominal ultrasound rarely yielded disease-specific or treatment-changing results.

Consensus recommendations on managing the selected comorbidities including cardiovascular disease, osteoporosis, and interstitial lung disease in rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA)-related comorbidities, including cardiovascular disease (CVD), osteoporosis (OP), and interstitial lung disease (ILD), are sub-optimally managed. RA-related comorbidities affect disease control and lead to impairment in quality of life. We aimed to develop consensus recommendations for managing RA-related comorbidities.

METHODS

The consensus statements were formulated based on emerging evidence during a face-to-face meeting of Taiwan rheumatology experts and modified through three-round Delphi exercises. The quality of evidence and strength of recommendation of each statement were graded after a literature review, followed by voting for agreement. Through a review of English-language literature, we focused on the existing evidence of management of RA-related comorbidities.

RESULTS

Based on experts' consensus, eleven recommendations were developed. CVD risk should be assessed in patients at RA diagnosis, once every 5 years, and at changes in DMARDs therapy. Considering the detrimental effects of nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids on CVD risks, we recommend using the lowest possible dose of corticosteroids and prescribing NSAIDs cautiously. The OP/fragility fracture risk assessment includes dual-energy X-ray absorptiometry and fracture risk assessment (FRAX) in RA. The FRAX-based approach with intervention threshold is a useful strategy for managing OP. RA-ILD assessment includes risk factors, pulmonary function tests, HRCT imaging and a multidisciplinary decision approach to determine RA-ILD severity. A treat-to-target strategy would limit RA-related comorbidities.

CONCLUSIONS

These consensus statements emphasize that adequate control of disease activity and the risk factors are needed for managing RA-related comorbidities, and may provide useful recommendations for rheumatologists on managing RA-related comorbidities.

Association of Prolonged Disease Duration and TG/HDL-C Ratio in Accelerating Atherosclerosis in Patients with Takayasu's Arteritis

Background and aim: Takayasu's arteritis (TA) is a chronic inflammation that frequently involves the aorta and its major branches. It has been known that atherosclerosis can occur in some TA patients. Objectives: This study aimed to identify the risk factors associated with the development of atherosclerosis in TA. Methods: This retrospective study enrolled a total of 101 TA patients. All patients were divided into two groups according to the absence or presence of atherosclerosis. Baseline demographic features and clinical characteristics were compared between two groups. A logistic model was applied to determine the risk factors associated with the development of atherosclerosis. Results: Our data suggested that the disease duration of patients in the atherosclerosis group was significantly longer than that of patients in the non-atherosclerosis group [96(18.00, 180.00) versus 48.00(12.00, 111.00) months] (P = .015). In addition, the average age of patients with atherosclerosis was significantly older compared to patients without atherosclerosis [44.00(38.00, 48.00)versus 28.50(24.00，37.00)years] (P < .001). Logistic regression analysis showed that the risk of developing atherosclerosis increased by 9.2% per 1 year increase in the disease duration (P = .005, OR 1.092, 95%CI: 1.027-1.162). Patients with TG/HDL-C ratio more than 0.8875 were associated with a 5.861fold increase of risk developing atherosclerosis (P < .001, OR 5.861, 95%CI: 2.299-14.939). Conclusion: Our study indicated that prolonged disease duration and elevated TG/HDL-C ratio are associated with the development of atherosclerosis in TA patients.
