EULAR recommendations for cardiovascular disease risk management in patients with rheumatoid arthritis and other forms of inflammatory joint disorders: 2015/2016 update

The Cardiovascular Safety of Tumour Necrosis Factor Inhibitors in Arthritic Conditions: A Structured Review with Recommendations

There is accumulating evidence that inflammation is a key driver of atherosclerosis development and thrombotic complications. This pathophysiological mechanism explains, at least in part, the increased cardiovascular risk of patients with immune-mediated arthritis. Experimental and clinical studies have shown that tumour necrosis factor (TNF) plays a pathological role in both vascular and joint diseases, suggesting that TNF inhibitors (TNFis) may limit cardiovascular events in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA) or spondyloarthritis (SpA). This review summarizes studies exploring the effects of TNFis on cardiovascular outcomes in patients with RA, PsA or SpA. Clinical studies suggest that TNFis reduce vascular inflammation and may improve (or prevent worsening of) endothelial dysfunction and arterial stiffness. There is evidence that TNFis reduce the incidence of cardiovascular events in patients with inflammatory arthritis compared with non-biological treatments, particularly in patients with rheumatoid arthritis. Fewer studies have compared the effects of different classes of biological therapy on outcomes, but found no significant difference in the risk of cardiovascular events between patients taking TNFis and other biological therapy. In contrast, patients at high cardiovascular risk may derive greater benefit from a TNFi than from a Janus kinase inhibitor (JAKi). The cardiovascular impact of JAKis is still under debate, with a recent safety warning. Targeted control of inflammation is a key strategy to reduce the risk of major adverse cardiovascular events in patients with inflammatory arthritis. Cardiovascular evaluation and risk stratification, using a multidisciplinary approach involving rheumatology and cardiology teams, are recommended to guide optimal immunomodulatory treatment.

The metabolic score for insulin resistance predicts the risk of cardiovascular disease in patients with psoriatic arthritis: results from the 10-year prospective CARMA cohort

OBJECTIVE

To evaluate the predictive value of the metabolic score for insulin resistance (METS-IR) in identifying patients with psoriatic arthritis (PsA) at high risk of cardiovascular (CV) events.

METHODS

Assessment of patients with PsA enrolled in the Spanish prospective CARdiovascular in ReuMAtology (CARMA) project. Baseline data from 500 PsA patients without a history of CV events, chronic kidney disease, diabetes mellitus or statin use at the baseline visit were analysed. Patients were prospectively followed for 10 years in rheumatology outpatient clinics at tertiary centres. The performance of the METS-IR in predicting CV events was evaluated. METS-IR was categorised into three groups: <2.25, 2.25-2.48 and >2.48.

RESULTS

Over 4788 patient-years of follow-up, 27 individuals experienced at least one CV event. The annualised incidence rate was 5.6 events per 1000 patient-years (95% CI: 3.7 to 8.2). PsA patients with CV events had significantly higher METS-IR scores than those without CV events (2.37±0.24 vs 2.26±0.19; p=0.01). In this regard, patients who had CV events were more commonly included in the METS-IR 2.25-2.48 and >2.48 categories than those without CV events (p=0.008). Adjusted regression models indicated that PsA patients with a METS-IR >2.48 at baseline had an increased risk of experiencing a CV event during the follow-up period.

CONCLUSIONS

In PsA patients under close observation in rheumatology units included in the prospective CARMA project, METS-IR serves as a reliable prognostic predictor of CV.

The lipid paradox is also present in early axial spondyloarthritis: results from the Swedish part of the SPondyloArthritis Caught Early (SPACE) cohort

OBJECTIVE

Inverse associations between systemic inflammation and cholesterol ('the lipid paradox') have been reported in rheumatoid arthritis (RA) and, in established axial spondyloarthritis (axSpA), but little is known about this relationship in early axSpA, which is the focus of the present study.

METHOD

In the Swedish part of the SPondyloArthritis Caught Early (SPACE) cohort (patients with chronic back pain for ≥3 months, ≤2 years; age at onset <45 years), serum levels of total cholesterol (TC) and apolipoproteins ApoA1 and ApoB were measured at inclusion, together with parameters reflecting inflammatory disease activity [C-reactive protein (CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), and sacroiliitis by magnetic resonance imaging (MRI) following Assessment of SpondyloArthritis international Society (ASAS) criteria]. All patients included in the analysis either had axSpA based on a high physician's level of confidence or fulfilled the ASAS criteria for axSpA. Associations between lipids/lipoproteins and inflammation were assessed using multivariable linear regression models.

RESULTS

In the 64 patients included, there were inverse associations for CRP with TC, ApoA1, and ApoB in age-sex-adjusted models. The negative associations with CRP remained significant for TC and ApoB in multivariable models adjusted for age, sex, BASDAI, and current smoking (p = 0.048). There were no significant associations for the lipid parameters with BASDAI or inflammation on MRI of the sacroiliac joints.

CONCLUSION

Inverse associations between systemic inflammation and lipids, particularly TC and ApoB, are present in early axSpA, similar to those shown for other inflammatory joint diseases. These patterns must be considered when including lipids in the evaluation of cardiovascular disease risk.

A review on the epidemiology of rheumatoid arthritis: An update and trends from current literature

Rheumatoid arthritis (RA) is a systemic, chronic autoimmune disease affecting mainly the joints, often with extra articular manifestations. This review provides an update on RA epidemiological trends and management. PubMed and EMBASE were searched from 2014 to 2024 using rheumatoid arthritis as keyword, combined with incidence, prevalence, diagnosis, classification, and management. Emphasis was on papers published in the past 5 years. Globally, the age-standardised prevalence and incidence rate (ASPR and ASIR) of RA increased with varying figures. The ASPR increased by 0.37%, 14.1%, and 6.4% from 1990 to 2019, 2020 and 2017 respectively; and 9% from 1980 to 2019. The ASIR increased by 0.3% and 8.2% from 1990 to 2019 and 2017 respectively; the disability-adjusted life years (DALY) figures increased 0.12% and decreased 0.36% in the same period from different authors. Reduction in ASIR were reported while ASPR varies. Disease modifying anti-rheumatic drugs (DMARDs) remain the cornerstone of treatment.

Association between bone mineral density and vascular health in rheumatoid arthritis

INTRODUCTION

Rheumatoid arthritis (RA) is associated with heightened cardiovascular disease and increased susceptibility to osteoporosis, with shared underlying mechanisms. This study aimed to investigate the association between vascular function and bone mineral density (BMD).

METHODS

We conducted a cross-sectional study of 49 patients with RA at Tan Tock Seng Hospital, Singapore. Endothelial function was measured as reactive hyperaemia index (RHI)-endothelial peripheral arterial tonometry and aortic stiffness as carotid-femoral pulse wave velocity (cf-PWV) using SphygmoCor. Univariable and multivariable linear regression analyses were performed to evaluate the associations between BMD and vascular function. We used natural logarithm RHI (lnRHI) and cf-PWV as response variables, and each BMD as covariate, adjusting for body mass index, positive anti-cyclic citrullinated peptide, cumulative prednisolone dose, hydroxychloroquine use and Systematic COronary Risk Evaluation 2.

RESULTS

We recruited 49 patients (mean age 61.08 ± 8.20 years), of whom 44 (89.80%) were women and 39 (81.25%) were Chinese. Significant associations were found between lnRHI and BMD at the lumbar spine (β = 0.4289, P = 0.037) and total hip (β = 0.7544, P = 0.014) in univariable analyses. Multivariable analyses confirmed these associations, showing that lower BMD at the lumbar spine (β = 0.7303, P = 0.001), femoral neck (β = 0.8694, P = 0.030) and total hip (β = 0.8909, P = 0.010) were significantly associated with worse lnRHI. No significant associations were found between BMD and cf-PWV.

CONCLUSION

Lower BMD is associated with endothelial dysfunction, but not aortic stiffness in patients with RA. Further longitudinal studies are needed to confirm these associations and understand the underlying mechanisms.

Evaluating the reliability of cardiovascular risk scales in patients with chronic inflammatory rheumatic diseases

OBJECTIVE

To compare the performance of the QRESEARCH risk estimator version 3 (QRISK3), the Systematic COronary Risk Evaluation (SCORE) 2, and Predicting Risk of cardiovascular disease EVENTs (PREVENT) equationin a cohort of individuals with chronic inflammatory rheumatic diseases (CIRD) enrolled in the Spanish prospective CARdiovascular in RheuMAtology (CARMA) project.

METHODS

Between July 2010 and January 2012, the study recruited CIRD patients from 67 hospitals across Spain. It included individuals diagnosed with rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis. At the 10-year follow-up, data for all patients included in the initial cohort were assessed. We estimated four 10-year cardiovascular disease (CVD) incidence risk scores using data recorded at recruitment.

RESULTS

2080 patients were included in this analysis. QRISK3 and PREVENT-CVD predicted an average of approximately 10 % CV events across the entire cohort, while SCORE2 and PREVENT-Atherosclerotic Cardiovascular Disease (ASCVD) predicted an average of only 6.3 %. The linear correlation coefficients between each pair of scales were consistently above 0.8, with an average of 0.9074. Notably, lower correlations were observed between QRISK3 and the other scales. When identifying patients with higher CV risk, the kappa index was higher between SCORE2, PREVENT-CVD, and PREVENT-ASCVD than between QRISK3 and any other scale. These findings suggest that most patients identified as high-risk by SCORE2 would also be classified as high-risk when using PREVENT-CVD or PREVENT-ASCVD.

CONCLUSIONS

The higher correlation and reliability observed between SCORE2, PREVENT-CVD, and PREVENT-ASCVD in our series of CIRD patients followed over a 10-year period suggest that these scales may be largely interchangeable for identifying high-risk CIRD patients.

Acute Coronary Syndrome and Rheumatic Disease

Patients with rheumatic disease and immune disorders have been noted to show an earlier development of atherosclerosis and to present with acute coronary syndrome. These diseases disproportionately affect women, and patients frequently have a higher number of comorbidities and other risk factors. Inflammation has long been known to play a role in the development of coronary artery disease. Early studies have shown some benefit in treatment targeting inflammation. While this has not been realized for all populations, there remains potential in treatment with targeted and individualized therapies. Especially since these diseases are associated with a worse prognosis, management benefits from the multidisciplinary expertise of cardiologists, rheumatologists, and other providers. However, the prevention and treatment of underlying rheumatic disease remains essential. This review will seek to highlight prior studies and future directions in the treatment of acute coronary syndrome in patients with rheumatologic disease.

Incidence of and predictive factors for lung cancer in patients with rheumatoid arthritis: A retrospective long-term follow-up study

OBJECTIVES

The aim of this study was to determine the incidence and predictive factors of lung cancer in rheumatoid arthritis (RA).

METHODS

We conducted a retrospective follow-up study of patients who were diagnosed with RA at our institution between April 2001 and December 2022. Pulmonary complications were evaluated using high-resolution computed tomography (HRCT) at RA diagnosis. Patients were followed until the diagnosis of lung cancer, diagnosis of other malignancies, death, loss to follow-up, or the end of the study.

RESULTS

Among 771 RA patients, 3.5% were diagnosed with combined pulmonary fibrosis and emphysema (CPFE), 4.9% with interstitial lung disease (ILD) alone, and 6.0% with emphysema alone. During follow-up (mean of 9.3 years), the crude incidence rates of lung cancer per 1000 patient-years were 2.9 in all patients, 47.8 in CPFE patients, 10.5 in ILD patients, 11.9 in emphysema patients, and 0.8 in patients without these complications. Only male patients showed a higher incidence of lung cancer compared with the general population. In multivariable Fine-Gray regression analysis, the presence of HRCT-proven CPFE, ILD, and emphysema, and smoking history were identified as predictive factors for lung cancer in RA patients.

CONCLUSIONS

Close monitoring of lung cancer is needed for RA patients with smoking history and pulmonary complications, especially CPFE.

Assessment of cardiovascular, thromboembolic and cancer risk in patients eligible for treatment with Janus Kinase inhibitors: The JAK-ERA multidisciplinary consensus

INTRODUCTION

JAK inhibitors (JAKi) have emerged as effective treatments for chronic inflammatory diseases, including gastrointestinal, dermatological, and rheumatological conditions. Despite their efficacy, concerns about their safety profile necessitate a comprehensive framework for their optimal use. This study aimed to establish an expert consensus (the JAK-ERA [Janus Kinase-inhibitors Evidence-based Risk Analysis] Multidisciplinary Expert Consensus) on the principles guiding JAKi therapy to maximize therapeutic benefits while mitigating risks.

METHODS

A Delphi method was employed, gathering opinions from experts across multiple disciplines. This iterative process involved rounds of surveys and feedbacks to synthesize diverse expert knowledge into a cohesive set of principles and consensus statements. The multidisciplinary panel included specialists in cardiology, oncology, hematology, gastroenterology, dermatology, and rheumatology.

RESULTS

A total of 6 overarching principles and 13 expert consensus statements were developed. The percentage of agreement ranged between 78 and 100 %. The principles highlight the importance of rapid intervention to prevent complications and alleviate psychological burdens. Detailed risk assessments for cardiovascular (CV), thromboembolic, and cancer risks were deemed essential. Recommendations included using validated tools for CV risk evaluation, comprehensive thromboembolic risk assessment, and routine cancer screenings based on standard protocols. Multidisciplinary collaboration was stressed to ensure precise risk management and optimal therapeutic outcomes.

CONCLUSION

The consensus provides a structured approach to JAKi therapy, balancing efficacy with safety considerations. The overarching principles and expert consensus statements offer a robust framework for clinical practice, ensuring that JAKi use is tailored to individual patient profiles, thereby enhancing outcomes and minimizing risks. Ongoing validation through prospective studies and real-world data is essential to further refine these recommendations.

Rheumatoid arthritis severity is mediated by crosstalk between synoviocytes and mature osteoclasts through a calcium and cytokine feedback loop

Fibroblast-like synoviocytes (FLSs) and osteoclasts are central cells in the maintenance of joint homeostasis. Rheumatoid arthritis (RA) is a chronic inflammatory disease of joints that induces cytokine-activated FLSs and progressive bone erosion. Interactions between FLSs and other cells, such as T cells and B cells, have been recognized in the development of RA. Here we hypothesized that calcium released from bone by mature osteoclasts might activate FLSs, which are also affected by inflammatory cytokines in the inflamed synovium. Osteoclastogenesis occurs in the presence of cytokine-stimulated FLS medium, and calcium released from the bone disc activates FLS migration. We first investigated the calcium and cytokine feedback loop between FLSs and osteoclast maturation. Moreover, by addressing the role of the sodium-bicarbonate cotransporter NBCn1 in osteoclastogenesis, we found that the inhibition of NBCn1 attenuated the infinite calcium and cytokine feedback loop between FLSs and osteoclasts. In a collagen-induced arthritis mouse model, the inhibition of NBC reduced the RA pathological phenotype and bone resorption area in the femur. These results suggest that modulation of the crosstalk between FLSs and osteoclasts by inhibiting the calcium and cytokine feedback loop could be considered to develop pioneering strategies to combat RA severity and dysregulated bone homeostasis.

Metabolomics for Distinguishing Cardiovascular Risk in Rheumatoid Arthritis Across Different Disease-Modifying Antirheumatic Drug Therapies

Background

Rheumatoid arthritis (RA) significantly increases the overall risk of cardiovascular disease (CVD). In addition to conventional risk factors, the inflammatory activity of the disease itself and medications that promote atherosclerosis contribute to an even greater risk. In this study, we performed metabolomic analysis in RA patients, both on and off disease-modifying anti-rheumatic drug (DMARD) therapy, with the aim of identifying new candidates for more sophisticated cardiovascular risk (CVR) assessment.

Methods

This is an observational, cross-sectional investigation that included patients with established RA. DMARD therapy, if prescribed, consisted of methotrexate (MTX) alone or in combination with other conventional disease-modifying anti-rheumatic drugs (cDMARDs) or biologic disease-modifying anti-rheumatic drugs (bDMARDs), or other cDMARDs or bDMARDs without MTX, respectively. Metabolomic profiling was conducted using a Bruker AVANCE NEO 600 MHz nuclear magnetic resonance (NMR) spectrometer. The spectra obtained were Fourier transformed using TopSpin software (version 4.0, Bruker Biospin, Germany). All spectra were automatically phased and subjected to baseline correction. Subsequently, the spectra were analyzed using the proprietary Profiler software (version 1.4_Blood, lifespin GmbH, Germany), and a quantitative metabolite list was generated.

Results

In total, 200 patients were included in the study, 54 subjects were not receiving any DMARDs (n = 47 untreated at the time of inclusion, n = 7 with established disease but not receiving DMARD therapy), and 146 were receiving DMARD treatment. No metabolic differences were found in relation to drug therapy or RA activity. The following CVR factors were associated with significant metabolic abnormalities: distress, arterial hypertension, diabetes mellitus and an average higher Framingham score. Distressed individuals showed abnormalities in histidine metabolism.

Conclusions

Our findings have aided in the identification of potential surrogate markers for assessing the burden of CVD in individuals with RA. Histidine may be of particular diagnostic importance in CVR assessment in RA.

Enhancing current guidance for psoriatic arthritis and its comorbidities: recommendations from an expert consensus panel

OBJECTIVES

The existing guidelines for PsA cover many aspects of management. Some gaps remain relating to routine practice application. An expert group aimed to enhance the current guidance and develop recommendations for clinical practice that are complementary to the existing guidelines.

METHODS

A steering committee comprising experienced, research-active clinicians in rheumatology, dermatology and primary care agreed on themes and relevant questions. A targeted literature review of PubMed and Embase following a PICO framework was conducted. At a second meeting, recommendations were drafted, and subsequently an extended faculty comprising rheumatologists, dermatologists, primary care clinicians, specialist nurses, allied health professionals, non-clinical academic participants and members of the Brit-PACT patient group, was recruited. Consensus was achieved via an online voting platform at which 75% of respondents agreed in the range of 7-9 on a 9-point scale.

RESULTS

The guidance comprised 34 statements covering four PsA themes. Diagnosis focused on strategies for identifying PsA early and referring appropriately, assessment of diagnostic indicators, use of screening tools and use of imaging. Disease assessment centred on holistic consideration of disease activity, physical functioning and impact from a patient perspective, and on how to implement shared decision-making. For comorbidities, recommendations included specific guidance on high-impact conditions such as depression and obesity. Management statements (which excluded extant guidance on pharmacological therapies) recommended multidisciplinary team working, implementation of lifestyle modifications and treat-to-target strategies. Minimizing CS use was recommended where feasible.

CONCLUSION

The consensus group have made evidence-based best-practice recommendations for the management of PsA to enhance the existing guidelines.

[Colchicine-Phoenix from the ashes]

Colchicine is an anti-inflammatory herbal medicine with a history stretching back thousands of years. It is a cornerstone in the acute and prophylactic treatment of gout and has secured a permanent place in the standard pharmacological repertoire for familial Mediterranean fever, pericarditis, neutrophilic dermatoses, Behçet's disease and severe aphthous ulcers refractory to oral treatment. The US Food and Drug Administration (FDA) has recently approved colchicine to reduce the risk of myocardial infarction, stroke, coronary revascularization and cardiovascular death in adult patients with established atherosclerotic disease or with multiple risk factors for cardiovascular diseases. The recommendation level for cardiovascular prophylaxis was raised from IIb to IIa in the current European Society of Cardiology (ESC) guidelines from 2024. Clinical studies in recent years also demonstrated an effect for acute coronary syndrome and atrial fibrillation. This review article highlights the efficacy and safety profile of colchicine and provides insights into recent and potential future evidence-based fields of application.

Recommendations for the primary prevention of atherosclerotic cardiovascular disease in primary care: a systematic guideline review

Introduction

This study systematically reviews and synthesizes recommendations from national and international clinical practice guidelines (CPGs) regarding the primary prevention of atherosclerotic cardiovascular disease (ASCVD) in adults in primary care settings.

Methods

CPGs were retrieved from MEDLINE, Trip, guideline repositories, and websites of guidelines-producing societies. Two reviewers independently screened the guidelines for eligibility, assessed their quality, and extracted study characteristics and relevant recommendations for further consistency analysis. Recommendations, with their strength and evidence level, were thematically coded and clustered around clinical questions using ATLAS.ti.

Results

We included 26 CPGs from which we extracted 581 recommendations on risk assessment, non-pharmacological, and pharmacological interventions. Twenty-one guidelines (81%) were rated as having "very good" methodological quality. We categorized the recommendations into 124 clusters. Forty-four clusters (35%) included consistent recommendations, but only four of them (3%) included highly consistent recommendations. These clusters emphasized avoiding routine prescriptions of nicotinic acid, aspirin, and fibrates for primary ASCVD prevention alone, and recommending 20 mg/day of atorvastatin for high-risk ASCVD patients. The recommendations also highlighted the importance of adhering to a Mediterranean-type diet, patient-centered counseling, and standardized risk assessment for patients over the age of 40.

Discussion

This review underscores the heterogeneity in primary ASCVD prevention recommendations and the importance of personalized strategies for at-risk individuals.

Cerebrovascular risk in rheumatoid arthritis patients: insights from carotid artery atherosclerosis in the Paracelsus 10,000 study

Rheumatoid arthritis (RA) is a chronic autoimmune disease marked by systemic inflammation. While RA primarily affects the joints, its systemic effects may lead to an increased cerebro- and cardiovascular risk. Atherosclerosis of the carotid arteries is a significant risk factor for cerebrovascular events and serves as a surrogate marker for cardiovascular risk. This study explores the link between RA and carotid artery atherosclerosis with data from the Paracelsus 10,000 Study. Baseline assessments were conducted on individuals randomly selected from Salzburg and its surrounding regions. Participants diagnosed with RA based on ACR-EULAR classification criteria and who underwent carotid artery ultrasound were included. Data were gathered from a total of 9729 participants, among whom 299 were diagnosed with RA. Carotid arteries were examined using ultrasound imaging. The primary endpoint was the difference in the prevalence of plaque presence between the RA and non-RA groups. One univariate (Model I) and three multivariate analyses were conducted, with adjustments in Model II incorporating SCORE 2, while Model III accounted for metabolic syndrome, age and sex. Additionally, Model IV included further adjustments for high-sensitivity C-reactive protein (hs-CRP). Plaque presence was defined as the ultrasound detection of plaque formation larger than 0 mm2, regardless of whether it was unilateral or bilateral. Additional assessments included carotid stenosis, intima-media thickness (IMT) and total plaque area (TPA). RA patients had a higher prevalence of plaque (50%) compared to non-RA individuals (38%). The odds ratio (OR) for plaque presence in RA patients versus non-RA individuals was 1.64 (95% CI 1.30-2.06). This association persisted after adjusting for SCORE2, with an adjusted odds ratio (aOR) of 1.65 (95% CI 1.26-2.15). The association remained significant when adjusting for metabolic syndrome, age and sex (aOR = 1.32, 95% CI 1.02-1.72) and also in Model IV, which included further adjustment for hs-CRP (OR = 1.33, 95% CI 1.02-1.74). The findings underscore an increased risk of cerebrovascular disease associated with RA. This study highlights the importance of thorough cerebrovascular and cardiovascular risk assessments, along with proactive management, for RA patients to reduce this risk. Recognizing the substantial impact of RA on stroke and cerebrovascular disease is important for enhancing patient care strategies. Carotid ultrasound appears to be an effective method for atherosclerosis screening in RA patients.

Residual Traditional Risk in Non-Traditional Atherosclerotic Diseases

Individuals with chronic inflammatory and immune disorders are at an increased risk of atherosclerotic events and premature cardiovascular (CV) disease. Despite extensive literature exploring the relationship between "non-traditional" atherosclerotic conditions and CV risk, many aspects remain unresolved, including the underlying mechanisms promoting the "non-traditional CV risk", the development of an innovative and comprehensive CV risk assessment tool, and recommendations for tailored interventions. This review aims to evaluate the available evidence on key "non-traditional" CV risk-enhancer conditions, with a focus on assessing and managing CV risk factors. We conducted a comprehensive review of 412 original articles, narrative and systematic reviews, and meta-analyses addressing the CV risk associated with "non-traditional" atherosclerotic conditions. The analysis examined the underlying mechanisms of these relationships and identified strategies for assessing and mitigating elevated risk. A major challenge highlighted is the difficulty in quantifying the contribution of individual risk factors and disease-specific elements to CV risk. While evidence supports the cardiovascular benefits of statins beyond lipid lowering, such as pleiotropic and endothelial effects, current guidelines lack specific recommendations for the use of statins or other therapies targeting non-traditional CV risk factors. Additionally, the absence of validated cardiovascular risk scores that incorporate non-traditional risk factors hinders accurate CV risk evaluation and management. The growing prevalence of "non-traditional CV risk-enhancer conditions" underscores the need for improved awareness of CV risk assessment and management. A thorough understanding of all contributing factors, including disease-specific elements, is crucial for accurate prediction of cardiovascular disease (CVD) risk. This represents an essential foundation for informed decision-making in primary and secondary prevention. We advocate for future research to focus on developing innovative, disease-specific CV risk assessment tools that incorporate non-traditional risk factors, recognizing this as a promising avenue for translational and clinical outcome research.

Cardiovascular risk according to biological agent exposure in patients with ankylosing spondylitis: a nationwide population-based study

OBJECTIVES

Patients with ankylosing spondylitis (AS) have a higher risk of cardiovascular events than controls. Although biological disease-modifying anti-rheumatic drugs (bDMARDs) are efficacious in treating AS, their effect on cardiovascular risk remains unclear. This study evaluated the effect of tumour necrosis factor inhibitors (TNFis) and interleukin-17 inhibitors (IL-17is) on cardiovascular risk in patients with AS.

METHODS

Data of 43,502 patients diagnosed with AS from 2010 onwards and without prior history of cardiovascular events were extracted from the Korean nationwide database. Cardiovascular events were defined as incident myocardial infarctions or strokes. Patients were followed-up through 2021. The risk of cardiovascular events was compared between TNFis exposure (vs. bDMARDs non-exposure), IL-17is exposure (vs. bDMARDs non-exposure), and IL-17is exposure (vs. TNFis exposure), using time-dependent Cox models.

RESULTS

The incidence rates of cardiovascular events during bDMARDs non-exposure, TNFis exposure, and IL-17is exposure were 18.66, 8.92, and 12.87 per 10,000 person-years, respectively. TNFis exposure (vs. bDMARDs non-exposure) was significantly associated with a lower risk of cardiovascular events (adjusted hazard ratio [aHR] = 0.697, 95% confidence interval [CI] = 0.499-0.973), whereas IL-17is exposure (vs. bDMARDs non-exposure) was not (aHR = 0.962, 95% CI = 0.134-6.920). The risk of cardiovascular events did not differ between IL-17is and TNFis exposures (aHR = 1.381, 95% CI = 0.189-10.087).

CONCLUSIONS

TNFis exposure (vs. bDMARDs non-exposure) was associated with approximately 30% lower risk of cardiovascular events in patients with AS. IL-17is exposure had no significant association with the risk of cardiovascular events compared with bDMARDs non-exposure or TNFis exposure. Key Points • TNFis exposure was associated with a 30% lower cardiovascular risk in patients with AS. • IL-17is exposure had no significant association with cardiovascular risk in patients with AS. • TNFis could be the preferred bDMARD with regard to cardiovascular risk in patients with AS.

Adherence to the 2019 ESC/EAS guidelines for dyslipidaemia management in a large rheumatoid arthritis cohort: Data from the CORDIS Study Group of the Italian Society of Rheumatology

BACKGROUND/AIM

Lipid-lowering therapy prescription is low in rheumatoid arthritis (RA) patients, often not achieving lipid threshold target despite treatment. However, evidence derives from small, monocentric cohorts. We assessed adherence to lipid-lowering treatment for primary cardiovascular (CV) prevention in a RA cohort according to international guidelines.

METHODS

A cross-sectional analysis of an Italian RA cohort was performed. Disease-related features and traditional CV risk factors were collected. The 10-year CV risk was estimated by Systematic COronary Risk Evaluation 2 (SCORE-2) algorithm. The primary preventive dyslipidaemia strategy was assessed according to 2019 European Society of Cardiology/European Atherosclerosis Society guidelines.

RESULTS

1.133 RA patients (78.2% female, aged 60.6±10.2 years) free from CV events were included. According to SCORE-2, 42.9% of patients were at moderate risk (1-5-%), 33.3% at high risk (5-10%) and 23.7% at very high risk (>10%). In the whole cohort, 12.9% of patients with <5%, 23.6% with 5-10% and 32.3% with >10% risk were on statin, respectively (p<0.001). According to 2019 ESC/EAS guidelines, 51.5% of patients had LDL-c at target. Among patients with LDL-c not at target, 76% were not on lipid-lowering treatment. At multivariate analysis, patients with higher CV risk had significantly lower probability of LDL-c at target.

CONCLUSION

In a wide Italian RA cohort, more than 50% of patients had high or very high CV risk. In these, lipid-lowering treatment prescription is suboptimal leading to not achievement of LDL-c target. Physicians should improve lipid screening and primary prevention therapy to reduce CV risk and improve CV comorbidity in RA patients.

Risk prediction model for psoriatic arthritis: NHANES data and multi-algorithm approach

OBJECTIVE

To develop a simplified predictive model for identifying psoriatic arthritis (PsA) in psoriasis patients.

METHODS

Data from the National Health and Nutrition Examination Survey (NHANES) database were analyzed, including patients with psoriasis without arthritis (PsC) or PsA. The least absolute shrinkage and selection operator, Boruta algorithm, random forest, and stepwise regression were employed to select key variables from 38 potential predictors. Logistic regression models were constructed for each combination of selected variables and evaluated using receiver operating characteristic (ROC) curves, precision-recall (PR) curves, calibration plots, Brier scores, and decision curve analysis (DCA).

RESULTS

The study included 587 patients with psoriasis, 238 of whom had PsA. The variable combinations proposed by the Boruta algorithm exhibited the best overall performance. Key predictors in the Borutamodel included age, fasting glucose, education level, thyroid disease, hypertension, and chronic bronchitis. This model achieved area under the curve (AUC) of 0.781 (95% CI, 0.737-0.826) for the training set and 0.780 (95% CI, 0.712-0.848) for the testing set in the ROC curve analyses. The AUC values in the PR curves were 0.687 (95% CI, 0.611-0.757) and 0.653 (95% CI, 0.535-0.770), respectively. The Brier scores of 0.186 and 0.191 for the testing and training sets indicated a good fit, further supported by the calibration curves. DCA showed a net clinical benefit for decision thresholds ranging from 0.2 to 0.8 in both datasets.

CONCLUSION

The Borutamodel represents a promising tool for early risk assessment of PsA. Key Points • National Database Utilization: This study leverages the NHANES database to predict psoriatic arthritis risk, addressing previous limitations tied to regional or ethnic constraints. • Comprehensive Variable Analyses: The research examines 38 variables, including demographics, health conditions, laboratory results, and lifestyle factors, using four distinct screening methods and thorough evaluations of model performance. • Innovative Risk Model: The study introduces a novel risk assessment model that integrates age, fasting glucose, education, and comorbidities including hypertension, thyroid disease, and chronic bronchitis, thus moving beyond traditional focus on skin lesions and joint symptoms.

Inadequate identification of high cardiovascular risk and carotid plaques in rheumatoid arthritis patients by the 2024 Predicting Risk of Cardiovascular EVENTs and the 2013 Atherosclerotic Cardiovascular Disease algorithms: findings from a Mexican cohort

The American College of Cardiology/American Heart Association introduced the Predicting Risk of Cardiovascular EVENTs (PREVENT™) algorithm to estimate the 10-year risk of developing cardiovascular disease. We aimed to assess the cardiovascular risk (CVR) reclassification among rheumatoid arthritis (RA) patients using traditional CVR algorithms-the 2024 PREVENT™ and the 2013 Atherosclerotic Cardiovascular Disease (ASCVD)-and the presence of carotid plaque (CP). This was a cross-sectional study nested of a RA patients' cohort. A certified radiologist performed a high-resolution B-mode carotid ultrasound to identify the presence of CP. The CVR evaluation was performed by a cardiologist, blinded to carotid ultrasound results, using the PREVENT™ and the ASCVD algorithms. Cohen's kappa (k) coefficient assessed concordance between high-risk classification by CVR algorithms and CP presence. ROC curve analysis evaluated the algorithms' capacity to identify RA patients with CP. The cutoff point was determined by the Youden-Index, with p < 0.05 as statistically significant. A total of 210 RA patients were included. The reclassification of CVR due to CP was 34.3% for the PREVENT™ algorithm and 30.0% for the ASCVD algorithm. Of these, 44.4% and 71.4%, respectively, were initially classified as low risk. Concordance between CVR algorithms and carotid ultrasound showed slight agreement (k = 0.032 and k = 0.130, respectively). The PREVENT™ algorithm did not identify more than one-third of high-CVR RA patients with indication of starting statin therapy based on carotid ultrasound findings. The PREVENT™ and ASCVD algorithms showed poor performance in identifying RA patients with CP. Key Points • The presence of CP was identified in more than a third of the evaluated RA patients (35.7%), classifying them as high CVR. • CVR reclassification by the presence of CP was observed in 34.3% RA patients with the PREVENTTM algorithm and in 30.0% RA patients with the ASCVD algorithm. • Most of the reclassified patients belonged to the low-risk category, 44.4% with the PREVENTTM algorithm and 71.4% with the ASCVD algorithm. • When evaluating the concordance between the ASCVD algorithm and the carotid ultrasound for high-risk classification, a slight agreement was found (k = 0.130).

Risk of cardiovascular disease associated with long-term use of non-steroidal anti-inflammatory drugs in ankylosing spondylitis

OBJECTIVE

To examine the risk of cardiovascular disease associated with long-term use of NSAIDs in a large real-world AS cohort.

METHODS

This nationwide population-based cohort study used data from the Korean National Health Insurance Database. Patients aged ≥18 years old who were newly diagnosed with AS without prior cardiovascular disease between January 2010 and December 2018 were included in this study. Controls without AS were randomly selected by age, sex and index year. The primary outcome was cardiovascular disease, a composite outcome of ischaemic heart disease, stroke or congestive heart failure. Long-term use of NSAIDs was defined as use of NSAIDs for >365 cumulative defined daily doses. The association between long-term use of NSAIDs and incident cardiovascular disease was examined in both AS and non-AS populations.

RESULTS

Among 19 775 patients with AS and 59 325 matched controls without AS, there were 1663 and 4308 incident cases of cardiovascular disease, showing an incidence of 16.9 and 13.8 per 1000 person-years, respectively. Long-term use of NSAIDs was associated with increased risk of cardiovascular disease in non-AS controls [adjusted hazard ratio (aHR) 1.64; 95% CI 1.48-1.82]. In contrast, long-term use of NSAIDs did not increase the risk of cardiovascular disease in AS patients (aHR 1.06; 95% CI 0.94-1.20; adjusted for age, sex, socioeconomic status, BMI, smoking status, hypertension, diabetes, hyperlipidemia and TNF inhibitor use).

CONCLUSION

Prolonged NSAID treatment in AS patients may not be as harmful as in the general population regarding cardiovascular risk.

Cardiovascular Implications of Non-steroidal Anti-inflammatory Drugs: A Comprehensive Review, with Emphasis on Patients with Rheumatoid Arthritis

This review examines the cardiovascular risks associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs), both traditional NSAIDs and cyclooxygenase-2 selective inhibitors (COXIBs). It describes the history of traditional NSAIDs and the development of COXIBs to explain why their cardiovascular side effects were unnoticed for many decades. Further, the review presents the mechanism of action of NSAIDs, to elucidate the possible underlying basis for why they are associated with an increased risk of cardiovascular disease. Finally, data on the cardiovascular risk with NSAID use in patients with rheumatoid arthritis are presented, and we propose possible explanations for why the risk of cardiovascular side effects in these patients seems to be less pronounced than in the general population.

Prevalence of comorbidities and cardiovascular risk factor management in hand osteoarthritis: a cross-sectional study

OBJECTIVES

To assess the prevalence of comorbidities and management of cardiovascular risk factors according to established guidelines for patients with hand osteoarthritis.

METHODS

A cross-sectional study was conducted that included 110 hand osteoarthritis patients. The clinical parameters (pain, function, grip strength, quality of life, sarcopenia, and comorbidities) were assessed along with cardiovascular (CV) risk factors (blood pressure, body mass index, and dyslipidaemia). CV risk was assessed using SCORE2 or SCORE2-OP algorithms. Comparisons of patient characteristics were performed using Student's or chi-squared tests.

RESULTS

Twenty-eight patients were identified with comorbidities, and they tended to be older, male, and with a lower quality of life. The median SCORE2 was 5.1%. SCORE2 was negatively associated with grip strength (r=-0.27, p = 0.02). There was no difference in SCORE2 between hand osteoarthritis patients with (n = 60) and without (n = 50) neuropathic-like pain (5.6 ± 3.7 versus 6.2 ± 3.3%; p = 0.38). Among the 40 patients with an intermediate or high CV risk, 33 (82.5%) were off target for low-density lipoproteins (LDL) level with no lipid-lowering treatment (n = 29) or an insufficient statin treatment (n = 4). Obesity was observed in 24 patients (21.8%) and 30 (27.3%) were overweight. Forty-two patients (41.2%) had blood hypertension (41 systolic and one diastolic patient) despite treatment for 9 patients.

CONCLUSIONS

We found an increased CV risk in hand osteoarthritis patients who had an insufficient LDL cholesterol target achievement. Hand osteoarthritis patients appear to have a pro-atherogenic profile. These results suggest that CV risk factors should be assessed in patients with hand osteoarthritis and managed according to recommended guidelines.

Haptoglobin 2-2 genotype is associated with increased risk of cardiovascular disease in patients with rheumatoid arthritis: a matched case-control study

Introduction

Traditional risk factors do not fully explain the increased risk of cardiovascular disease (CVD) in patients with rheumatoid arthritis (RA). The Haptoglobin (Hp) 2-2 genotype confers a lower anti-oxidant and higher inflammatory effect on the vasculature compared to the non-Hp 2-2 genotype. This study investigates the association of the Hp genotype with CVD in patients with RA.

Methods

Data from 69 RA patients with CVD and 207 sex- and ethnicity-matched RA patients without CVD, collected from 1 January 2000 to 31 December 2020, were retrieved from the Tan Tock Seng Hospital RA Registry. CVD was examined against demographics, clinical and laboratory variables in univariate models. Associations between the Hp genotypes and CVD were analyzed using conditional logistic regression.

Results

We studied 276 patients (65.2% female, 82.6% Chinese, median age 60.9 years). Most participants were in low disease activity or remission (79.3%). The Hp 2-2 genotype was present in 49.6% (137/276). In the group with CVD, the prevalence of the Hp 2-2 genotype was 50.9% (29/57) in the Chinese, 100% (5/5) in the Indians, and 28.6% (2/7) in the Malays. In the non-CVD group, the respective prevalence was 46.8% (80/171), 66.7% (10/15), and 52.4% (11/21). In univariate analysis, the matched odds ratio (OR) of the Hp 2-2 genotype for CVD in RA was 1.34 [95% confidence interval (CI): 1.22-1.47; p < 0.001]. The Hp 2-2 genotype was significantly associated with CVD (adjusted matched OR: 1.13; 95% CI: 1.01-1.27; p = 0.033) in the multivariate logistic regression model after adjusting the confounding factors, including age, smoking, diabetes, hypertension, hyperlipidemia, anti-CCP autoantibodies, and disease activity.

Conclusion

The Hp 2-2 genotype is associated with an increased risk of CVD in patients with RA in this multi-ethnic cohort.

SCORE2 is superior to SCORE in predicting the presence of carotid plaques and intima-media thickness in rheumatoid arthritis patients: a cross-sectional study using carotid ultrasound

Background

Rheumatoid arthritis (RA) increases the risk of premature mortality, primarily due to cardiovascular diseases (CVD). While Systematic Coronary Risk Evaluation (SCORE) and its updated version SCORE2 are used to estimate CVD risk, these tools may not adequately capture the full cardiovascular risk profile in RA patients.

Objectives

This study aims to compare the effectiveness of SCORE2 versus SCORE in predicting the presence of carotid plaques or increased intima-media thickness (IMT), as detected by ultrasound, in RA patients.

Design

This was a single-center cross-sectional study and included adult RA patients with moderate to severe disease who initiated treatment with Janus kinase inhibitors or anti-tumor necrosis factor inhibitors between September 2022 and April 2023.

Methods

Both SCORE and SCORE2 were calculated for each patient. Carotid ultrasound examinations documented the presence of plaques, and IMT was measured.

Results

A total of 122 patients were included. The mean SCORE was 2.48%, while SCORE2 was significantly higher at 4.07% (p < 0.01). SCORE identified 12 (10%) patients as high risk, while SCORE2 identified 99 (81%). Atherosclerotic plaques were present in 34% (n = 42) of participants. Traditional cardiovascular risk factors (dyslipidemia, diabetes, hypertension, and smoking) were significantly associated with ultrasound-detected risk. In 87 cases where SCORE was underestimated, 34 patients (39%) classified as low-moderate risk by SCORE were correctly reclassified as high risk by SCORE2. However, 54 cases classified as high risk by SCORE2 had normal carotid ultrasounds. The sensitivity of SCORE for predicting plaque presence was 21%, compared to 100% for SCORE2. Combining SCORE with carotid ultrasound increased the detection of high-risk patients from 10% to 38%. However, adding carotid ultrasound to SCORE2 did not increase the detection rate beyond 81%.

Conclusion

Our findings highlight the superior performance of SCORE2 compared to SCORE in identifying RA patients with carotid ultrasound abnormalities, thus indicating a higher cardiovascular risk.

High-intensity interval training improves cardiovascular and physical health in patients with rheumatoid arthritis: a multicentre randomised controlled trial

OBJECTIVES

Patients with rheumatoid arthritis (RA) have substantially elevated risk for cardiovascular diseases, and low cardiorespiratory fitness (VO2max) is a major mediator. The aim of this assessor-blinded, two-armed multicentre randomised controlled trial was to evaluate the effects of high-intensity interval training (HIIT) and strength exercise on cardiovascular health, physical fitness and overall health in patients with RA.

METHODS

In total, 87 patients (86% female; aged 20-60 years) were randomly assigned to an intervention group (IG) or a control group (CG). The IG performed HIIT and strength exercise for 12 weeks. The CG was instructed to be physically active on a moderately intensive level, ≥150 min/week. Primary outcome was change in VO2max. Secondary outcomes were changes in anthropometry measures, muscle strength, overall health (Visual Analogue Scale (VAS)-Global), Patient Global Impression of Change (PGIC), pain and disease activity (Disease Activity Score in 28 joints (DAS28)).

RESULTS

There was a significant mean group difference of change on VO2max (3.71 mL/kg/min; 95% CI 2.16, 5.25) in favour of the IG. Significant mean group differences of change were also seen for O2-pulse (1.38; 95% CI 0.85 to 1.91), waist circumference (-2.6; 95% CI -5.09 to -0.18), 1-minute sit-to-stand (5.0; 95% CI 3.35 to 6.72), handgrip strength (28.5; 95% CI 3.80 to 52.8), overall health (-14.7; 95% CI -23.8 to -5.50) and PGIC (p<0.0001) in favour of the IG. No significant mean group differences of change were found for pain (-4.0; 95% CI -13.07 to 5.06), DAS28 (-0.25; 95% CI -0.60 to 0.10) and erythrocyte sedimentation rate (-0.64; 95% CI -3.23 to 1.90).

CONCLUSION

Supervised HIIT and strength exercise improved cardiovascular health, physical fitness and overall health without a deterioration in pain and disease activity and should be considered in patients with well-controlled RA.

Managing Cardiovascular Risk in Patients with Autoimmune Diseases: Insights from a Nutritional Perspective

PURPOSE OF REVIEW

Autoimmune diseases manifest as an immune system response directed against endogenous antigens, exerting a significant influence on a substantial portion of the population. Notably, a leading contributor to morbidity and mortality in this context is cardiovascular disease (CVD). Intriguingly, individuals with autoimmune disorders exhibit a heightened prevalence of CVD compared to the general population. The meticulous management of CV risk factors assumes paramount importance, given the current absence of a standardized solution to this perplexity. This review endeavors to address this challenge from a nutritional perspective.

RECENT FINDINGS

Emerging evidence suggests that inflammation, a common thread in autoimmune diseases, also plays a pivotal role in the pathogenesis of CVD. Nutritional interventions aimed at reducing inflammation have shown promise in mitigating cardiovascular risk. The integration of nutritional strategies into the management plans for patients with autoimmune diseases offers a holistic approach to reducing cardiovascular risk. While conventional pharmacological treatments remain foundational, the addition of targeted dietary interventions can provide a complementary pathway to improve cardiovascular outcomes.

Tofacitinib Safety and Effectiveness in Canadian Patients with Rheumatoid Arthritis by Cardiovascular Risk Enrichment: Subanalysis of the CANTORAL Study

INTRODUCTION

ORAL Surveillance, a post-authorisation safety study of patients with rheumatoid arthritis (RA) enriched for cardiovascular (CV) risk, demonstrated increased risk of major adverse CV events (MACE) and malignancies (excluding non-melanoma skin cancer [NMSC]) for tofacitinib versus tumour necrosis factor inhibitors (TNFi). This analysis of a real-world Canadian observational study evaluated tofacitinib safety/effectiveness in patients meeting or not meeting CV risk criteria.

METHODS

CANTORAL included patients with moderate-to-severe RA initiating tofacitinib (10/2017-07/2020; N = 504). Interim data (data-cut: 07/2021) were stratified as CV risk-enriched (CV+ ; patients ≥ 50 years with ≥ 1 additional CV risk factor) or not CV risk-enriched (CV-; ≥ 50 years without additional CV risk factors and 18-49 years with/without CV risk factors). Safety and persistence were evaluated to month (M) 36. Effectiveness outcomes to M18 included Clinical Disease Activity Index (CDAI)-defined low disease activity (LDA)/remission (CANTORAL co-primary endpoints) and Disease Activity Score in 28 joints, C-reactive protein (DAS28-4[CRP]) < 3.2/ < 2.6.

RESULTS

Overall, 272/232 patients were included in CV+ /CV- cohorts (full analysis set) (435/356 patient-years [safety analysis set]). Incidence rates (events/100 patient-years) in CV+ /CV- cohorts were 138.5/112.5 for treatment-emergent adverse events (AEs); 17.0/5.6 for serious AEs; 1.2/0.3 for deaths; 5.5/1.7 for serious infections; 1.4/1.1 for herpes zoster; 1.6/0.0 for MACE; 2.1/0.3 for malignancies (excluding NMSC); 0.7/0.6 for NMSC; 0.5/0.0 for venous thromboembolic events. Persistence was generally comparable between cohorts. In CV+ /CV- cohorts, at M6, CDAI LDA and remission rates were 51.5%/54.6% and 12.0%/19.6%; DAS28-4(CRP) < 3.2/ < 2.6 rates were 44.0%/39.3% and 31.5%/28.8%, respectively; effectiveness was generally maintained to M18.

CONCLUSIONS

In concordance with studies of background risk, AEs were more common in patients with CV risk enrichment, particularly those aged ≥ 65 years. Tofacitinib effectiveness/persistence were generally similar regardless of CV risk enrichment. These findings support individualised treatment benefit-risk assessment, including CV assessment/management, to optimise RA outcomes.

Management strategies in rheumatoid arthritis

Management of rheumatoid arthritis (RA) has evolved from simply the direct translation of drug efficacy results from clinical trials to patient care, to a more complex longitudinal process that considers not only drug efficacy but also the safety gestalt of a treatment and patient profiles and preferences, as well as health-economic factors. With numerous DMARDs available to treat RA, knowledge about trial efficacy becomes less important than data that inform an appropriate clinical strategy for their optimal selection and use. Overly ambitious approaches targeting the 'maximum' level of success could, for example, be prone to failure and create frustration, and lead to a large number of patients then being considered as 'difficult to treat'. Safety profiles might be more informative than efficacy profiles for precision medicine approaches. Contemporary RA management strategies might therefore take a more holistic approach, beyond merely efficacy, to the setting of targets that lead to improved compliance rather than aspirational successes, with consideration of each patient's multimorbidity profile and preferences, as well as the safety profile of each treatment. Ultimately, the goal remains unchanged: maximizing health-related quality of life; however, with a focus on optimal balance rather than superlatives.

Efficacy and Safety of Tofacitinib in Patients with Psoriatic Arthritis or Ankylosing Spondylitis by Cigarette Smoking Status

INTRODUCTION

Routine care studies of psoriatic arthritis (PsA) and ankylosing spondylitis (AS) demonstrated attenuated responses to tumor necrosis factor inhibitors in current/past versus never smokers. This post hoc analysis assessed tofacitinib efficacy and safety in patients with PsA or AS by cigarette smoking status at trial screening.

METHODS

Pooled data from phase 3 and long-term extension (safety only) PsA trials and phase 2 and 3 AS trials were assessed by current/past versus never smoker status. Analysis included efficacy and safety data for tofacitinib 5 (PsA/AS) and 10 (PsA only) mg twice daily (BID) or placebo, and safety data in AS for tofacitinib 2 and 10 mg BID. Efficacy outcomes included American College of Rheumatology ≥ 50% responses (ACR50) and minimal disease activity (MDA) responses to month (M)6/M3 (tofacitinib/placebo) in PsA; and ≥ 40% improvement in Assessment of SpondyloArthritis international Society responses (ASAS40) and AS Disease Activity Score (ASDAS) < 2.1 responses to week (W)16 in AS. Safety was assessed to M48/W48 (PsA/AS), adjusted for treatment/smoking status/median body mass index (BMI) status/sex/trial/treatment-smoking status interaction.

RESULTS

PsA/AS cohorts included 342/178 current/past and 572/194 never smokers. Tofacitinib efficacy was generally greater versus placebo to M3/W6 (PsA/AS), and comparable in current/past and never smokers to M6/W16 (PsA/AS). In patients receiving ≥ 1 tofacitinib dose, adjusted treatment-emergent adverse event (TEAE)/serious AE (SAE)/discontinuation due to AE incidence rates (IRs) to M48 in PsA were higher in current/past versus never smokers; adjusted IRs to W48 in AS were higher in current/past versus never smokers for TEAEs, but similar for SAEs/discontinuation due to AEs.

CONCLUSIONS

In both patients with PsA and AS, tofacitinib efficacy was greater versus placebo, and comparable across smoking categories. Adjusted IRs were higher in current/past versus never smokers for TEAEs, SAEs, discontinuation due to AEs in PsA, and for TEAEs in AS, complementing reports of associations between smoking and comorbidities in spondyloarthritis. Findings support increased surveillance/caution for patients with PsA or AS with smoking history.

Immune-Mediated Inflammatory Diseases, Dyslipidemia, and Cardiovascular Risk: A Complex Interplay

Individuals with autoimmune inflammatory diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and psoriasis, are at increased risk for cardiovascular disease. While these diseases share common features of systemic inflammation, the impact of individual autoimmune inflammatory conditions on circulating lipids and lipoproteins varies by specific disease, disease activity, and the immune-suppressing medications used to treat these conditions. A common feature observed in many autoimmune inflammatory diseases is the development of a proatherogenic dyslipidemic state, characterized by dysfunctional HDLs (high-density lipoproteins) and increased oxidation of LDLs (low-density lipoproteins). Various disease-modifying antirheumatic drugs also have complex and variable effects on lipids, and it is critical to take this into consideration when evaluating lipid-related risk in individuals with immune-mediated inflammatory conditions. This review aims to critically evaluate the current understanding of the relationship between immune-mediated inflammatory diseases and dyslipidemia, the underlying mechanisms contributing to atherogenesis, and the impact of various pharmacotherapies on lipid profiles and cardiovascular risk. We also discuss the role of lipid-lowering therapies, particularly statins, in managing residual risk in this high-risk population and explore the potential of emerging therapies with complementary anti-inflammatory and lipid-lowering effects.

A comparison of comorbidities and their risk factors prevalence across rheumatoid arthritis, psoriatic arthritis and axial spondyloarthritis with focus on cardiovascular diseases: data from a single center real-world cohort

Management of comorbidities is essential to a patient-centered approach to the treatment of chronic inflammatory arthritis. The aim of this study was to compare the prevalence of comorbidities and their risk factors in rheumatoid arthritis (RA), psoriatic arthritis (PsA), and axial spondyloarthritis (axSpA) in a single center outpatient cohort. This cross-sectional study included adult patients diagnosed with RA, PsA, and axSpA from a single rheumatology outpatient center. Comorbidities were documented by physicians, and patients were categorized into two age groups, younger (< 45 years) and older (≥ 45 years), with age- and gender-based comparisons. Disease activity, comorbidities, and cardiovascular (CV) risk factors were analyzed using chi-squared tests for categorical variables and independent samples t-tests for continuous variables, with p values < 0.05 considered statistically significant. Comorbidities were registered by physicians using GoTreatIt® Rheuma software. Among 508 RA, 267 PsA, and 285 axSpA patients, the four most common comorbidities were hypertension (36.4%, 25.1%, and 19.7%, respectively), dyslipidemia (19.5%, 15.4%, 14.7% respectively), obesity (16.9%, 22.5%, 14% respectively) and thyroid disease (21.5%, 13.9%, 11.2% respectively). Other comorbidities differed among the diseases and included osteoporosis, osteoarthritis, diabetes mellitus, arrhythmia, and asthma in RA, diabetes mellitus, depression and asthma in PsA, osteoporosis and serious infection in axSpA. RA patients, compared to axSpA had a higher prevalence of coronary artery disease (4.1% vs. 0.7%, p = 0.006), arrhythmia (6.9% vs. 2.5%, p = 0.008) and major adverse cardiac events (2.6% vs. 0.4%, p = 0.024) compared to axSpA. Osteoporosis was more frequent in RA (19.1%) and axSpA (8.4%) than in PsA (2.3%; p < 0.001) and was frequently diagnosed in patients aged < 45. Depression prevalence was surprisingly low (1.6%, 5.2%, and 1.8%, respectively). RA patients had the highest multimorbidity rate, with 26.6% reporting three or more comorbidities, compared to 16.8% in PsA and 10.6% in axSpA (p < 0.001). Health status was poorest in RA and worse in women compared to men for all diseases. RA, PsA, and axSpA share the same four most common comorbidities: hypertension, dyslipidemia, obesity, and thyroid disease but have different prevalence of other disorders and CV risk factors, indicating the need for an individual screening and prevention approach. The possible unrecognition of depression should be evaluated.

Lifestyle discussions facilitate self-management in RA: a qualitative study of patients' perceptions

BACKGROUND

Healthy lifestyle habits (regular physical activity, a healthy diet, no smoking and non-hazardous alcohol consumption) alongside pharmacological treatment can lower the risk of cardiovascular diseases and improve symptoms and quality of life in patients with rheumatoid arthritis (RA). Therefore, healthcare professionals in rheumatology care are urged to discuss lifestyle habits with all patients. The aim of this study was to explore patients' perceptions of lifestyle discussions in early rheumatology care.

METHODS

Individual interviews were conducted with 20 patients with RA, 14 women and six men, aged 23 to 77 years, and with a mean disease duration of 2.4 years. All lifestyle discussions were performed during the first year with RA. A qualitative content analysis was performed.

RESULTS

An overarching theme emerged, exploring how patients with RA perceived lifestyle discussions as facilitating self-management. Three categories illustrated this: (1) the usefulness of lifestyle discussions depended on the individual patient's preferences and prioritization for lifestyle support; (2) the design of lifestyle discussions should be based on a person-centred approach, incorporating personalized lifestyle information and providing structured and recurrent support; (3) the outcomes of lifestyle discussions should contribute to enhanced knowledge and motivation for making healthy lifestyle changes.

CONCLUSION

Lifestyle discussions in early rheumatology care should, according to patients with RA, be based on a person-centred approach, be tailored to each patient's preferences and needs, and have outcomes focusing on patient support for healthy lifestyle changes, all essential elements to facilitate self-management. The present findings can be used to guide the development and implementation of more person-centred lifestyle approaches targeted to facilitate lifestyle changes and benefit cardiovascular disease risk management in early rheumatology care.

Spanish Working Group in Crohn's Disease and Ulcerative Colitis (GETECCU) position paper on cardiovascular disease in patients with inflammatory bowel disease

Cardiovascular diseases (CVD) are the leading cause of death worldwide. Therefore, it is essential to understand their relationship and prevalence in different diseases that may present specific risk factors for them. The objective of this document is to analyze the specific prevalence of CVD in patients with inflammatory bowel disease (IBD), describing the presence of classical and non-classical cardiovascular risk factors in these patients. Additionally, we will detail the pathophysiology of atherosclerosis in this patient group and the different methods used to assess cardiovascular risk, including the use of risk calculators in clinical practice and different ways to assess subclinical atherosclerosis and endothelial dysfunction. Furthermore, we will describe the potential influence of medication used for managing patients with IBD on cardiovascular risk, as well as the potential influence of commonly used drugs for managing CVD on the course of IBD. The document provides comments and evidence-based recommendations based on available evidence and expert opinion. An interdisciplinary group of gastroenterologists specialized in IBD management, along with a consulting cardiologist for this type of patients, participated in the development of these recommendations by the Spanish Group of Work on Crohn's Disease and Ulcerative Colitis (GETECCU).

Interleukin-6: Cardiovascular Aspects of Long-Term Cytokine Suppression in Patients with Rheumatoid Arthritis

In recent years, many atherogenesis researchers have focused on the role of inflammatory cytokines in the development of cardiovascular disease (CVD). Interleukin-6 (IL-6) cytokine is independently associated with higher CVD risk in patients with rheumatoid arthritis (RA). The effect of IL-6 inhibitors on the cardiovascular system in RA patients remains poorly understood, especially with its long-term use. This study investigates the effect of therapy with IL-6 receptor blocker tocilizumab (TCZ) on the dynamics of cardiovascular risk (CVR), modifiable risk factors (RFs), carotid artery (CA) structural changes, and the incidence of cardiovascular complications (CVCs) in RA patients during a 265-week follow-up period. Forty-five patients with active RA (DAS28-ESR 6.2 (5.5;6.8) with ineffectiveness and/or intolerance to disease-modifying antirheumatic drugs (DMARDs) were included in this study. During long-term therapy with TCZ in RA patients, no increase in CVR and no significant structural changes in CA were observed. No significant changes in the blood lipid spectrum were observed in patients without statin therapy. In the group of patients receiving statins, there was a 43% increase in high-density lipoprotein cholesterol (HDL-C), a 15% reduction in total cholesterol levels, and a 56% decrease in the atherogenicity index (p < 0.01 in all cases). Associations were found between ∆ total cholesterol and ∆ C-reactive protein (CRP) (R = 0.36, p = 0.04), ∆ low-density lipoprotein cholesterol (LDL-C), and ∆-CRP (R = 0.42, p = 0.03) in RA patients receiving statins. Initially, the thickness of the intima-media complex of carotid arteries (cIMT) positively moderately correlated with age (R = 0.7; p < 0.01), BMI (R = 0.37; p < 0.01), and systolic blood pressure (R = 0.64; p < 0.01); however, it weakly correlated with the lipid spectrum parameters: total cholesterol (R = 0.29; p < 0.01) and LDL-C (R = 0.33; p < 0.01). No new associations of cIMT by the end of the follow-up period, as well as the relationship of cIMT value with RA activity and therapy, were revealed. Patients with carotid ASPs showed an oppositely directed relationship between total cholesterol and sVCAM-1 at baseline (R = -0.25, p = 0.01) and at the end of this study (R = 0.29, p < 0.01). The incidence of cardiovascular events was 0.53 per 100 patient-years during the 265-week period of TCZ therapy.

Cardio-Rheumatology Insights Into Hypertension: Intersection of Inflammation, Arteries, and Heart

There is an increased prevalence of atherosclerotic cardiovascular disease (ASCVD) in patients with inflammatory rheumatic diseases (IRD) including rheumatoid arthritis, systemic lupus erythematosus, psoriatic arthritis, and systemic sclerosis. The mechanism for the development of ASCVD in these conditions has been linked not only to a higher prevalence and undertreatment of traditional cardiovascular (CV) risk factors but importantly to chronic inflammation and a dysregulated immune system which contribute to impaired endothelial and microvascular function, factors that may contribute to accelerated atherosclerosis. Accurate ASCVD risk stratification and optimal risk management remain challenging in this population with many barriers that include lack of validated risk calculators, the remitting and relapsing nature of underlying disease, deleterious effect of medications used to manage rheumatic diseases, multimorbidity, decreased mobility due to joint pain, and lack of clarity about who bears the responsibility of performing CV risk assessment and management (rheumatologist vs. primary care provider vs. cardiologist). Despite recent advances in this field, there remain significant gaps in knowledge regarding the best diagnostic and management approach. The evolving field of Cardio-Rheumatology focuses on optimization of cardiovascular care and research in this patient population through collaboration and coordination of care between rheumatologists, cardiologists, radiologists, and primary care providers. This review aims to provide an overview of current state of knowledge about ASCVD risk stratification in patients with IRD, contributing factors including effect of medications, and review of the current recommendations for cardiovascular risk management in patients with inflammatory disease with a focus on hypertension as a key risk factor.

Sex Differences in Cardiovascular Risk Profiles of Patients with Rheumatoid Arthritis: Results from an Italian Multicentre Cohort

Objective: The effect of sex and gender-related variables on the evaluation of cardiovascular (CV) risk in rheumatoid arthritis patients has been poorly explored. We investigated the differences in CV risk features and scores according to sex in a wide rheumatoid arthritis (RA) cohort. Methods: This is a cross-sectional analysis of a consecutive RA cohort. Disease-specific clinical and serologic variables, traditional CV risk factors and the 10-year CV risk calculated by the SCORE-2, Progetto CUORE and Expanded Risk Score-RA algorithms were compared in males and females. Results: A total of 820 patients (193 men, 627 women) were included. Disease activity was similar between the two sexes. A significantly higher prevalence of traditional CV risk factors and higher mean CV risk scores were detected in male compared to female patients. In the multiple linear regression analysis, a higher HAQ, csDMARD use and ACPA positivity were significantly associated with an increased CV risk in females, while b/tsDMARDs was associated with a lower CV risk in males according to different algorithms. Conclusions: The distribution of traditional CV risk factors and the 10-year risk of CV disease significantly differed in female and male patients despite similar disease activity. Disease-specific variables may contribute differently to CV risk according to sex. The CV screening in RA should also take into account the different distribution of CV risk factors between sexes.

Risk factors and assessment of subclinical atherosclerosis in patients with psoriatic arthritis

OBJECTIVE

To understand the prevalence of subclinical atherosclerosis (SCA) in psoriatic arthritis (PsA) patients; to explore the correlation between PsA combined with SCA and traditional cardiovascular risk factors and disease activity; to compare the role of Framingham Risk Score (FRS) and atherosclerotic cardiovascular disease (ASCVD) scores.

METHODS

We included 50 PsA patients who met the CASPAR classification criteria, 50 diabetes patients and 50 healthy people. Clinical data were collected from all patients, minimal disease activity (MDA), disease activity index for psoriatic arthritis (DAPSA), ASCVD, FRS were assessed in patients with PsA, and carotid artery intima-media thickness was measured.

RESULTS

The prevalence of SCA in PsA patients was significantly higher than that in healthy controls (44% vs 24%, P<0.05). Smoking, drinking, ASCVD, FRS were the risk factors of PsA with SCA (P<0.05). Psoriasis (PsO) duration, PtGA, VAS and DAPSA were the risk factors for PsA with SCA (P<0.05). FRS and ASCVD scores underestimated SCA risk in PsA patients.

CONCLUSION

Compared with healthy controls, patients with PsA have higher prevalence of SCA. High DAPSA is a risk factor for PsA with SCA. Carotid ultrasound can monitor SCA in patients with PsA, improve stratification of cardiovascular risk.

[Influence of smoking, nutrition and other modifiable environmental factors on rheumatoid arthritis]

Numerous reports in recent years have focused on the influence of environmental factors on rheumatoid arthritis. This article provides an overview of the current study situation on the influence of modifiable environmental factors on the development and course of rheumatoid arthritis. Lifestyle factors, such as cigarette smoking, diet, exercise and body weight can be individually influenced. Factors such as air pollution and socioeconomic status can be influenced by environmental and sociopolitical measures at a public level. Epidemiological studies have identified nicotine abuse, an unhealthy diet and obesity as well as a low level of education and social status as risk factors for the development of rheumatoid arthritis. Numerous factors are also associated with a poorer response to treatment and a worse prognosis. As randomized interventional studies on most environmental factors are hardly feasible, the causal relationship of the individual factors to the incidence and progression of rheumatoid arthritis is difficult to quantify. Nevertheless, the current evidence already enables the provision of appropriate counselling to patients with rheumatoid arthritis with respect to a healthy lifestyle including abstaining from cigarette smoking, maintaining a healthy diet, physical activity and avoiding obesity.

Hypertension and Cardiovascular Outcomes in Inflammatory and Autoimmune Diseases: A Systematic Review and Meta-analysis

PURPOSE

This review aimed to investigate the prevalence of hypertension and cardiovascular (CV) complications in various inflammatory and autoimmune diseases (IAD).

RECENT FINDINGS

Despite recent improvements in the management of IAD, patients with IAD still have an increased CV mortality and CV complications, mostly related to CV risk factors such as hypertension and inflammation. We systematically searched MEDLINE and EMBASE libraries for controlled studies involving hypertension and CV complications in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis including psoriatic arthritis (PsA), Sjogren's syndrome (SS), or antineutrophil cytoplasmic antibody-associated vasculitis (AAV) between January 2000 and March 2022. We extracted data on the prevalence of hypertension and CV complications. Then, random-effects meta-analyses and exploratory multivariate meta-regression were performed to explore factors related to the prevalence of hypertension. Of 2726 studies screened, 122 were selected for the meta-analysis. The prevalence of hypertension was higher among patients with IAD than controls, with an overall unadjusted odds ratio (OR) [95% confidence interval] of 1.67 [1.58-1.76] and an adjusted OR of 1.36 [1.24-1.50]. All diseases were found to be associated with increased risk of hypertension: SLE, adjusted OR 3.40 [1.93-6.00]; psoriasis, OR 1.32 [1.16-1.51]; PsA, OR 1.49 [1.15-1.94]; RA, OR 1.28 [1.04-1.58]; SS, OR 2.02 [1.19-3.44]. Age and female sex were significantly associated with hypertension in patients with IAD. The risk of CV complications was increased: ischemic heart disease, adjusted OR 1.38 [1.21-1.57]; cerebrovascular disease, OR 1.37 [1.03-1.81]; heart failure, OR 1.28 [1.05-1.55]; atherosclerotic plaques presence, OR 2.46 [1.84-3.29]. The prevalence of hypertension and CV complications is higher among patients with IAD. Screening and management of hypertension appears to be of paramount importance in these patients.

Rheumatoid Arthritis and Heart Failure: A Narrative Review

Rheumatoid arthritis (RA) is a chronic inflammatory process involving the joints and the cartilage. Early diagnosis and treatment of RA are crucial to prevent further complications like heart failure (HF), cervical subluxation, membranous glomerulonephritis, and parenchymal lung disease. HF is the leading cause of death in various chronic illnesses. The pathophysiology of HF varies based on the type of illness. In this review, our main objective was to look into the association between RA and HF by examining the pathogenesis, risk factors, and treatment of HF in RA. We also discuss the role of the inflammatory markers associated with HF in the pathogenesis. The treatment of anti-inflammatory drugs in HF associated with RA is also discussed. We also address the risk factors associated with RA so that the development of complications like HF can be reduced in this patient population.

Autoimmune diseases and atherosclerotic cardiovascular disease

Autoimmune diseases are associated with a dramatically increased risk of atherosclerotic cardiovascular disease and its clinical manifestations. The increased risk is consistent with the notion that atherogenesis is modulated by both protective and disease-promoting immune mechanisms. Notably, traditional cardiovascular risk factors such as dyslipidaemia and hypertension alone do not explain the increased risk of cardiovascular disease associated with autoimmune diseases. Several mechanisms have been implicated in mediating the autoimmunity-associated cardiovascular risk, either directly or by modulating the effect of other risk factors in a complex interplay. Aberrant leukocyte function and pro-inflammatory cytokines are central to both disease entities, resulting in vascular dysfunction, impaired resolution of inflammation and promotion of chronic inflammation. Similarly, loss of tolerance to self-antigens and the generation of autoantibodies are key features of autoimmunity but are also implicated in the maladaptive inflammatory response during atherosclerotic cardiovascular disease. Therefore, immunomodulatory therapies are potential efficacious interventions to directly reduce the risk of cardiovascular disease, and biomarkers of autoimmune disease activity could be relevant tools to stratify patients with autoimmunity according to their cardiovascular risk. In this Review, we discuss the pathophysiological aspects of the increased cardiovascular risk associated with autoimmunity and highlight the many open questions that need to be answered to develop novel therapies that specifically address this unmet clinical need.

Effects of pedicle subtraction osteotomy on aortic morphology and hemodynamics in ankylosing spondylitis with kyphosis: a finite element analysis study

Osteotomy can correct kyphosis, restore the spinal sequence, and restore the healthy appearance of a patient. However, the aorta is stretched during pedicle subtraction osteotomy (PSO), and some surgeons are concerned about aortic injury. We used finite element analysis to construct an aortic model to simulate hemodynamic changes during osteotomy. 16 patients with ankylosing spondylitis kyphosis who had undergone a two-level osteotomy at the L1 and L3 levels was included in this study. Aortic computed tomography angiography (CTA) was performed, and a 3D image model was constructed. The length, transverse diameter, and curvature of the aorta were used to evaluate morphological changes. Finite element analysis was used to analyze the changes in aortic fluid dynamics. Blood pressure, wall shear stress, and blood flow velocity were compared pre- and postoperatively. The overall length of the aorta before surgery was 424.3 ± 42.9 mm, and the overall length of the aorta after surgery was 436.2 ± 54.8 mm. The aortic curvature decreased from 0.27 ± 0.13 to 0.17 ± 0.09. The mean transverse diameter of the aorta did not change (19.3 ± 6.6 vs. 19.2 ± 7.4 mm, P > 0.05). The blood flow velocity (2.8 ± 1.1 vs. 1.5 ± 0.8 m/s, P < 0.05), blood pressure (6.6 ± 1.7 vs. 4.3 ± 1.2 Kpa, P < 0.05), and wall shear stress (47.6 ± 17.3 vs. 22.3 ± 8.6, P < 0.05) at the T10-L4 level decreased postoperatively. Changes in LL were significantly correlated with changes in ld, dc, blood flow velocity, blood pressure and wall shear stress (ld : r = 0.713, P < 0.001; dc: r = 0.626,P = 0.010; blood flow velocity: r= - 0.541, P = 0.041; blood pressure: r = - 0.601, P = 0.016; wall shear stress: r= - 0.594, P = 0.027). The aorta was stretched, and its curvature decreased. The mean transverse diameter of the aorta did not change. Blood flow velocity, blood pressure, and wall shear stress decreased after surgery. Our study provides hemodynamic support for the possible cardiovascular benefits of osteotomes.

Disease response in rheumatoid arthritis across four biologic therapies associates with improvement in paraoxonase-1 activity and oxylipins

OBJECTIVE

Paraoxonase-1 (PON1) is a high-density lipoprotein (HDL)-associated enzyme, that has been implicated as a biomarker of cardiovascular risk in patients with rheumatoid arthritis (RA). We aimed to investigate how different biologic therapies affect levels of PON1 and oxylipins.

METHODS

1213 adult patients with RA in the Comparative Effectiveness Registry to study Therapies for Arthritis and Inflammatory CoNditions cohort study with moderate-to-high disease activity (Clinical Disease Activity Index (CDAI) >10) who initiated a new biologic (tocilizumab (TCZ), n=296; abatacept, n=374; tumour necrosis factor inhibitors, n=427; rituximab, n=116) were followed prospectively with serum specimens analysed for PON1 activity by arylesterase (ARYL), lactonase (LAC) and PON assays at baseline and after 6 months of biologic therapy. A targeted panel of oxylipins was evaluated by liquid chromatography-mass spectrometry/mass spectrometry in a subset of patients with the lowest and highest 6-month Disease Activity Score 28 (DAS28)-C reactive protein (CRP) responses in each treatment group.

RESULTS

PON1 activity generally increased in the entire cohort after 6 months of new biologic therapy, showing the greatest, most consistent increases in the TCZ group. Increases in all three PON1 domains associated with significant decreases in disease activity in DAS28-CRP/CDAI (p<0.05), and increases in LAC/ARYL were significantly associated with the American College of Rheumatology 20/50/70 responses (OR (95% CI) of 1.12 (1.04, 1.22) and 1.13 (1.04, 1.23), p<0.01, respectively), after controlling for other RA disease characteristics. Some oxylipins, including 12-hydroxyeicosatetraenoic acid correlated with RA disease activity measures.

CONCLUSION

Improvement in disease activity across four classes of biologics is associated with enhanced PON1 activity, which has significant implications for cardiovascular safety.

Twenty-Week Dietary Supplementation with Beeswax Alcohol (BWA; Raydel®) Ameliorates High-Cholesterol-Induced Long-Term Dyslipidemia and Organ Damage in Hyperlipidemic Zebrafish in a Dose-Dependent Manner: A Comparative Analysis Between BWA and Coenzyme Q10

BACKGROUND/OBJECTIVES

Beeswax alcohol (BWA; Raydel®) is a blend of six long-chain aliphatic alcohols extracted from honeybee wax and is well known for its diverse functionality and health benefits. Herein, the efficacy of a BWA dietary intervention for 20 weeks was assessed to ameliorate high-cholesterol diet (HCD)-induced dyslipidemia and adverse effects on the vital organs of adult zebrafish.

METHODS

Adult zebrafish were fed different high-cholesterol diets (HCDs; final concentration of 4%, w/w) supplemented with BWA (final concentrations of 0.1%, 0.5% and 1.0%, w/w) or CoQ10 (final concentration of 1.0%). Following 20 weeks of supplementation, blood and different organs (liver, kidney, testes and ovaries) were collected, and biochemical, histological and immunohistochemical analyses were performed.

RESULTS

The results demonstrate a dose-dependent effect of BWA of mitigating HCD-induced mortality in zebrafish over the 20-week supplementation period, which was noticeably better than the effect exerted by coenzyme Q10 (CoQ10). Consistently, a dose-dependent effect of BWA consumption of curtailing HCD-induced total cholesterol (TC) and triglyceride (TG) levels and increasing high-density-lipoprotein cholesterol (HDL-C) levels was noticed. Compared with CoQ10 (final concentration of 1.0%, w/w), BWA (final concentration of 1.0%, w/w) displayed a significantly better effect of mitigating HCD-induced dyslipidemia, as evidenced by 1.2-fold (p < 0.05) and 2.0-fold (p < 0.05) lower TC and TG levels and 2.4-fold (p < 0.01) higher HDL-C levels. The histological analysis revealed substantial prevention of fatty liver changes, reactive oxygen species (ROS) generation, cellular senescence and interleukin (IL)-6 production in the hepatic tissue of BWA zebrafish, which was significantly better than the effect exerted by CoQ10. Consistently, compared with CoQ10, significant 25% (p < 0.05) and 35% (p < 0.01) reductions in the HCD-induced elevated levels of the hepatic function biomarkers aspartate aminotransferase and alanine aminotransferase was observed in the BWA group. Likewise, BWA consumption efficiently ameliorated HCD-induced kidney, ovary and testis damage by inhibiting ROS generation, cellular senescence and lipid accumulation.

CONCLUSION

Supplementation with BWA demonstrated higher therapeutic potential than that with CoQ10 to prevent dyslipidemia and organ damage associated with long-term consumption of HCDs.
