Optimal Monitoring For Coronary Heart Disease Risk in Patients with Systemic Lupus Erythematosus: A Systematic Review

A Case of Anti-OJ Antibody-positive Antisynthetase Myopathy Diagnosed after Pulmonary Embolization

Idiopathic inflammatory myopathies, such as dermatomyositis, are implicated as possible risk factors for venous thromboembolism. We herein report the first known case of a 50-year-old woman who presented to our hospital with a fever, chest pain, and elevated creatine kinase levels and was ultimately diagnosed with pulmonary embolism and anti-OJ antibody-positive antisynthetase myopathy. Dermatomyositis may increase the risk of venous thromboembolism, including pulmonary embolism. However, only a few cases of pulmonary embolism developing before the diagnosis of inflammatory myositis have been reported. Idiopathic inflammatory myopathy should be considered as a differential diagnosis when creatine kinase levels are elevated in patients with pulmonary embolism.

French protocol for the diagnosis and management of systemic lupus erythematosus

Because Systemic Lupus Erythematosus (SLE) is a rare disease, and due to the significant prognostic impact of early management, a diagnosis confirmed by a physician with experience in SLE is recommended, for example from an expert center. Once the diagnosis is confirmed, existing manifestations should be identified in particular, renal involvement by an assessment of proteinuria, disease activity and severity should be determined, potential complications anticipated, associated diseases searched for, and the patient's socioprofessional and family context noted. Therapeutic management of SLE includes patient education on recognizing symptoms, understanding disease progression as well as when they should seek medical advice. Patients are informed about routine checkups, treatment side effects, and the need for regular vaccinations, especially if they are receiving immunosuppressive treatment. They are also advised on lifestyle factors such as the risks of smoking, sun exposure, and dietary adjustments, especially when they are receiving corticosteroids. The importance of contraception, particularly when teratogenic medications are being used, and regular cancer screening are emphasized. Support networks can help relieve a patient's isolation. The first-line medical treatment of SLE is hydroxychloroquine (HCQ), possibly combined with an immunosuppressant and/or low-dose corticosteroid therapy. The treatment of flares depends on their severity, and typically involves HCQ and NSAIDs, but may be escalated to corticosteroid therapy with immunosuppressants or biologic therapies in moderate to severe cases. Because there is no curative treatment, the goals of therapy are patient comfort, preventing progression and flares, and preserving overall long-term health and fertility. The frequency of follow-up visits depends on disease severity and any new symptoms. Regular specialized assessments are necessary, especially when treatment changes, but a frequency of every 3 to 6 months is recommended during periods of remission and monthly during active or severe disease, especially in children. These assessments include both clinical and laboratory tests to monitor complications and disease activity, with specific attention to proteinuria.

The impact of traditional cardiovascular risk factor control on 7-year follow-up atherosclerosis progression in systemic lupus erythematosus

OBJECTIVES

The 2022 EULAR recommendations for cardiovascular risk management in patients with rheumatic disorders, including SLE, call for rigorous management of cardiovascular risk factors (CVRF). The impact of CVRF target attainment on atherosclerotic plaque progression hasn't been previously evaluated in prospective ultrasound studies.

METHODS

A total of 115 patients with SLE and 1:1 age and sex-matched healthy controls who had a baseline carotid and femoral ultrasound examination in our cardiovascular research unit were invited for a 7-year follow-up assessment of new plaque development. We aimed to compare the incidence of plaque progression between SLE patients and controls and reveal the extent to which it is affected by the attainment of European Society of Cardiology (ESC) targets for modifiable CVRFs (blood pressure, smoking status, body weight, lipids and physical activity), and disease-related features (disease duration, disease activity, autoantibodies, treatments).

RESULTS

Eighty-six SLE patients and 42 controls had a 7-year follow-up carotid and femoral plaque examination. New plaque development was observed in 32/86 patients vs 8/42 controls (P = 0.037). Patients with SLE had a 4-fold higher risk for plaque progression than controls (OR: 4.16, CI: 1.22, 14.19, P = 0.023), adjusting for potential confounders. Multivariate regression analyses showed a 50% decrease in plaque progression for every modifiable CVRF fulfilling ESC targets (OR: 0.56, CI: 0.34, 0.93, P = 0.026).

CONCLUSION

Patients with SLE develop a rapid progression of atherosclerotic plaques which may be drastically reduced by CVRF target attainment according to ESC guidelines.

Lipid management in systemic lupus erythematosus according to risk classifiers suggested by the European Society of Cardiology and disease-related risk factors reported by the EULAR recommendations

BACKGROUND

The European Alliance of Associations for Rheumatology recommended that lipid-lowering therapy (LLT) in systemic lupus erythematosus (SLE) should follow general population guidelines. We examined the eligibility for LLT in SLE according to Systematic Coronary Risk Evaluation (SCORE), with and without the addition of vascular ultrasound (VUS) and disease-related features.

METHODS

210 patients with SLE without prior cardiovascular events, diabetes or antiphospholipid syndrome underwent cardiovascular risk assessment with SCORE. LLT eligibility was evaluated in low-risk and moderate-risk patients following European Society of Cardiology (ESC) guidelines. Atherosclerotic plaques on carotid ultrasound (cUS)) and carotid and femoral ultrasound (cfUS), prolonged disease duration (PDD, ≥10 years), failure to achieve lupus low disease activity state (LLDAS_no), cumulative glucocorticoid 'cardiovascular harm' dose (GC_CVH, optimal cut-off to predict ultrasound-detected plaques) and antiphospholipid antibody positivity (aPL_pos) were tested as SCORE risk enhancers for classification ability (phi coefficient) and agreement (Cohen's kappa) using SCORE plus cfUS as a reference modality for LLT eligibility.

RESULTS

Plaques were detected in 9.9% of low-risk cases and 54.6% of moderate-risk cases. SCORE alone would indicate 0% of low-risk patients and 3% of moderate-risk patients for LLT eligibility. According to SCORE+cfUS, 9.9% of low-risk patients and 57.6% of moderate-risk patients, respectively, would be eligible for LLT based on ESC guidelines. Ιn low-risk/moderate-risk patients, phi values for SCORE+PDD, GC_CVH (cut-off ≥11 g), LLDAS_no and aPL_pos in antiplatelet-naïve antiphospholipid antibody-positive (aPL_pos/_APT-) cases were 0.06/0.13, 0.23/0.20, 0.07/0.16 and 0.06/0.33, respectively. Agreement for LLT eligibility to SCORE+cfUS was better for SCORE+PDD in moderate-risk patients and for SCORE+cUS in both groups of patients. SCORE+GC_CVH and SCORE+aPL_pos showed at least fair agreement (kappa ≥0.20) to SCORE+cfUS in low-risk or moderate-risk and in aPL_pos/APT- moderate-risk patients, respectively.

CONCLUSION

Disease-related and VUS features, in addition to SCORE, may help to improve LLT decision making in SLE. GC_CVH and aPL_pos improve LLT eligibility similarly and to a greater degree than PDD or LLDAS_no.

Timing and Predictors of Incident Cardiovascular Disease in Systemic Lupus Erythematosus: Risk Occurs Early and Highlights Racial Disparities

OBJECTIVE

Systemic lupus erythematosus (SLE) affects Black people 2 to 3 times more frequently than non-Black people and is associated with higher morbidity and mortality. In total, 4 studies with predominantly non-Black SLE cohorts highlighted that cardiovascular disease (CVD) is no longer primarily a late complication of SLE. This study assessed the timing and predictors of incident CVD in a predominantly Black population-based SLE cohort.

METHODS

Incident SLE cases from the population-based Georgia Lupus Registry were validated as having a CVD event through review of medical records and matching with the Georgia Hospital Discharge Database and the National Death Index. The surveillance period for an incident CVD event spanned a 15-year period, starting from 2 years prior to SLE diagnosis.

RESULTS

Among 336 people with SLE, 253 (75%) were Black and 56 (17%) had an incident CVD event. The frequency of CVD events peaked in years 2 and 11 after SLE diagnosis. There was a 7-fold higher risk of incident CVD over the entire 15-year period; this risk was 19-fold higher in the first 12 years in Black people as compared to non-Black people with SLE. Black people with SLE (P < 0.001) and those with discoid rash (hazard ratio 3.2, 95% CI 1.4-7.1) had a higher risk of incident CVD events.

CONCLUSION

The frequency of incident CVD events peaked in years 2 and 11 after SLE diagnosis. Being Black or having a discoid rash were strong predictors of an incident CVD event. Surveillance for CVD and preventive interventions, directed particularly toward Black people with recent SLE diagnoses, are needed to reduce racial disparities.

Non-Traditional Pro-Inflammatory and Pro-Atherosclerotic Risk Factors Related to Systemic Lupus Erythematosus

Cardiovascular diseases (CVD) are one of the leading causes of high mortality in patients with systemic lupus erythematosus (SLE). The Framingham risk score and other traditional risk factors do not fully reflect the CVD risk in SLE patients. Therefore, in order to stratify these high-risk patients, additional biomarkers for subclinical CVD are needed. The mechanisms of atherogenesis in SLE are still being investigated. During the past decades, many reports recognized that inflammation plays a crucial role in the development of atherosclerosis. The aim of this report is to present novel proinflammatory and pro-atherosclerotic risk factors that are closely related to SLE inflammation and which determine an increased risk for the occurrence of early cardiovascular events.

Study of common hypertriglyceridaemia genetic variants and subclinical atherosclerosis in a group of women with SLE and a control group

OBJECTIVE

SLE is associated with increased cardiovascular risk (CVR). High serum concentrations of triglyceride-rich lipoproteins and apolipoprotein B-rich particles constitute the characteristic dyslipidaemia of SLE.

METHODS

A cross-sectional study was conducted to study the relationship between genetic variants involved in polygenic hypertriglyceridaemia, subclinical atherosclerosis and lipoprotein abnormalities. 73 women with SLE and 73 control women age-matched with the case group were recruited (age range 30-75 years). Serum analysis, subclinical atherosclerosis screening studies for the detection of plaque, and genetic analysis of the APOE, ZPR1, APOA5 and GCKR genes were performed.

RESULTS

Triglyceride concentrations and the prevalence of hypertension, dyslipidaemia and carotid atherosclerosis were higher in women with SLE than in the control group. Multivariate logistic regression showed that CC homozygosity for the GCKR rs1260326 gene (OR=0.111, 95% CI 0.015 to 0.804, p=0.030) and an increase of 1 mmol/L in triglyceride concentrations were associated with a greater risk of carotid plaque in women with SLE (OR=7.576, 95% CI 2.415 to 23.767, p=0.001).

CONCLUSIONS

GCKR CC homozygosity (rs1260326) and serum triglyceride concentrations are independently associated with subclinical carotid atherosclerosis in women with SLE. Subclinical carotid atherosclerosis is also more prevalent in these women compared with the control group. The study of GCKR rs1260326 gene variants may contribute to more precise assessment of CVR and modulation of the intensity of lipid-lowering treatment in patients with SLE.

Characteristics and risk factors of severe coronary artery disease in systemic lupus erythematosus: A multicenter, Chinese Rheumatism Date Center database study

AIM

Systemic lupus erythematosus (SLE) with severe coronary artery disease (CAD) is associated with increased mortality. This study aimed to assess the characteristics and risk factors of severe CAD in SLE.

METHOD

This multicenter, cross-sectional study enrolled consecutive patients with SLE included in the Chinese Rheumatism Date Center registry. Patients with severe CAD including angiography-confirmed stenosis ≥50% in the left main, ≥70% in other major coronary arteries, or myocardial infarction were classified into the CAD group. Patients without CAD were classified into the control group. Subgroups were stratified according to age (set as above and below 45 and 50 for men and women, respectively) and gender. Binary logistic regression analysis was performed to determine independent risk factors of severe CAD in SLE.

RESULTS

Forty-three patients had severe CAD from a total of 3744 patients with SLE, 30 of whom were female; 35 belonged to the older age group and 8 belonged to the younger age group. In older patients, independent risk factors included age, 5 major CAD risk factors, SLE Disease Activity Index 2000 (SLEDAI-2K), hyperuricemia, and corticosteroid exposure. In younger patients, the risk factors were 5 major CAD risk factors and positive antiphospholipid antibody (APL). Male risk factors were age and 5 major CAD risk factors, whereas female risk factors were age, 5 major CAD risk factors, SLEDAI-2K, and positive APL. Three-vessel disease was most prevalent in patients with severe CAD.

CONCLUSION

We recommend screening for severe CAD in patients with SLE with age- and gender-stratified risk factors.

Association of Renal Arteriosclerosis With Atherosclerotic Cardiovascular Disease Risk in Lupus Nephritis

OBJECTIVE

Lupus nephritis (LN) predicts a 9-fold higher atherosclerosis cardiovascular disease (ASCVD) risk, highlighting the urgent need to target ASCVD prevention. Studies in IgA nephropathy reported that severe renal arteriosclerosis (r-ASCL) in diagnostic biopsies strongly predicted ASCVD risk. We recently found that 50% of LN pathology reports overlooked r-ASCL reporting, which could explain prior negative LN ASCVD risk studies. The present study was undertaken to examine associations between a composite of reported and overread r-ASCL and ASCVD events in LN.

METHODS

Data were abstracted from all LN patients who underwent diagnostic biopsy between 1994 and 2017, including demographic information, ASCVD risk factors, and pathology reports at the time of LN diagnosis. We manually validated all incident ASCVD events. We overread 25% of the biopsies to grade r-ASCL using the Banff criteria. We supplemented the overread r-ASCL grade, when available, to determine the composite of reported and overread r-ASCL grade.

RESULTS

Among 189 incident LN patients, 78% were female, 73% White, and the median age was 25 years. Overall, 31% had any reported r-ASCL, and 7% had moderate-to-severe r-ASCL. After incorporating systematically re-examined r-ASCL grade, the prevalence of any and moderate-to-severe r-ASCL increased to 39% and 12%, respectively. We found 22 incident ASCVD events over 11 years of follow-up. Using a composite of reported and overread r-ASCL grade, we found that severe r-ASCL in diagnostic LN biopsies was associated with 9-fold higher odds of ASCVD.

CONCLUSION

Severe r-ASCL can predict ASCVD in LN; therefore, larger studies are required to systematically report r-ASCL and examine ASCVD associations.

Extent of vascular plaque predicts future cardiovascular events in patients with systemic lupus erythematosus

OBJECTIVE

Patients with SLE have increased prevalence of clinical cardiovascular disease (CVD) and subclinical atherosclerosis. Although 30-40% of patients with SLE have vascular plaque on ultrasound scanning, this study is the first to consider the relationship between total burden of plaque and subsequent CVD risk.

METHODS

One hundred patients with SLE and without any previous clinical CVD underwent vascular ultrasound scans of both carotid and both common femoral bifurcations between 2011 and 2013. Clinical, serological, demographic and treatment data were collected at baseline. Patients were followed till 2020 to identify those who developed new onset coronary disease or stroke. Statistical analysis to identify factors associated with increased risk of developing CVD events was carried out.

RESULTS

Thirty-six patients had plaque at baseline. During follow-up five patients (all had baseline plaque) developed coronary disease and two, without baseline plaque, developed lacunar strokes. Mean (s.d.) age of these patients was 46.5 (4.5) years. Patients with three or more baseline bifurcations with plaque were 10 times more likely to develop CVD than those with 0-2 bifurcations with plaques (OR 9.9, P = 0.009). TPA > 16mm2 was associated with six-fold increased risk of CVD (OR = 6.44, P = 0.028). Patients with disease duration > 14 years were more likely than those with disease duration < 14 years to develop CVD (OR 8.3 P = 0.043).

CONCLUSIONS

The number of bifurcations with plaque and TPA in patients with SLE may be valuable in assessing risk of CVD and deciding on clinical measures to reduce this risk.

Endothelial function and endothelial progenitor cells in systemic lupus erythematosus

The observations that traditional cardiovascular disease (CVD) risk factors fail to fully account for the excessive cardiovascular mortality in patients with systemic lupus erythematosus (SLE) compared with the general population have prompted in-depth investigations of non-traditional, SLE-related risk factors that contribute to cardiovascular complications in patients with SLE. Of the various perturbations of vascular physiology, endothelial dysfunction, which is believed to occur in the earliest step of atherosclerosis, has been extensively investigated for its contribution to CVD risk in SLE. Endothelial progenitor cells (EPCs), which play a crucial part in vascular repair, neovascularization and maintenance of endothelial function, are quantitatively and functionally reduced in patients with SLE. Yet, the lack of a unified definition of EPCs, standardization of the quantity and functional assessment of EPCs as well as endothelial function measurement pose challenges to the translation of endothelial function measurements and EPC levels into prognostic markers for CVD in patients with SLE. This Review discusses factors that contribute to CVD in SLE, with particular focus on how endothelial function and EPCs are evaluated currently, and how EPCs are quantitatively and functionally altered in patients with SLE. Potential strategies for the use of endothelial function measurements and EPC quantification as prognostic markers of CVD in patients with SLE, and the limitations of their prognostication potential, are also discussed.

Non-ST-elevation myocardial infarction hiding behind myopericarditis in a patient with systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a chronic inflammatory condition with various cardiovascular sequelae. Pericarditis is the most common cardiac manifestation, yet patients also have a markedly elevated risk of premature atherosclerosis and acute coronary syndrome (ACS). This makes the diagnosis of ischaemic chest pain both challenging and crucial in these patients. Here, we examine the case of a 39-year-old male who presented with acute myopericarditis and pericardial tamponade in the setting of newly diagnosed SLE. Several days later, the patient experienced an infero-septal non-ST-elevation myocardial infarction. Urgent percutaneous coronary intervention showed 100% proximal right coronary artery (RCA) occlusion with subsequent placement of two overlapping drug-eluting stents to the proximal-mid RCA. This case illustrates the need to carefully evaluate patients with SLE for underlying cardiovascular disease regardless of age or the presence of tradition risk factors. Recognition of the increased incidence of ACS in SLE patients is crucial for early diagnosis and revascularisation.

Retracted: Effect of dipeptidyl peptidase-4 inhibitors on the progression of atherosclerosis in patients with type 2 diabetes mellitus: A meta-analysis of randomised controlled trials

Yang, T, Li, W, Kan, Z, Liu, Y, Peng, M, Shi, H, Effect of dipeptidyl peptidase-4 inhibitors on the progression of atherosclerosis in patients with type 2 diabetes mellitus: A meta-analysis of randomised controlled trials. Int J Clin Pract. 2021; 00:e14213. https://onlinelibrary.wiley.com/doi/10.1111/ijcp.14213. The above article from the International Journal of Clinical Practice, published online on 5 April 2021 in Wiley Online Library (wileyonlinelibrary.com), has been retracted at the request of the authors, and by agreement of the journal Editor in Chief, Charles Young, and John Wiley and Sons Ltd. The retraction has been agreed following an author review of the research which led to the removal of some studies which did not meet the inclusion criteria. Following the removal of these studies the overall sample size was too small and the studies still included too heterogenuous for the results and conclusions to be reliable.

Assessment and management of the heightened risk for atherosclerotic cardiovascular events in patients with lupus erythematosus or dermatomyositis

For patients with lupus erythematosus (LE) or dermatomyositis (DM), there is an urgent need to address a heightened risk of clinical events, chiefly heart attacks and strokes, caused by atherosclerotic cardiovascular disease (ASCVD). Patients with LE or DM frequently exhibit high levels of conventional risk factors for ASCVD events, particularly dyslipoproteinemia and hypertension; an amplified burden of atherosclerotic plaques; and increased age- and sex-adjusted rates of ASCVD events compared with the general population. The rate of ASCVD events exceeds what would be expected from conventional risk factors, suggesting that disease-specific autoimmune processes exacerbate specific, known pathogenic steps in atherosclerosis. Importantly, despite their heightened risk, patients with LE or DM are often undertreated for known causative agents and exacerbators of ASCVD. Herein, we propose an approach to assess and manage the heightened risk of ASCVD events in patients with LE or DM. Our approach is modeled in large part on established approaches to patients with diabetes mellitus or stage 3 or 4 chronic kidney disease, which are well-studied conditions that also show heightened risk for ASCVD events and have been explicitly incorporated into standard clinical guidelines for ASCVD. Based on the available evidence, we conclude that patients with LE or DM require earlier and more aggressive screening and management of ASCVD. We suggest that physicians consider implementing multipliers of conventional risk calculators to trigger earlier initiation of lifestyle modifications and medical therapies in primary prevention of ASCVD events, employ vascular imaging to quantify the burden of subclinical plaques, and treat to lower lipid targets using statins and newer therapies, such as PCSK9 inhibitors, that decrease ASCVD events in nonautoimmune cohorts. More clinical vigilance is needed regarding surveillance, prevention, risk modification, and treatment of dyslipidemias, hypertension, and smoking in patients with LE or DM. All of these goals are achievable.

Cardiovascular Health in Pediatric Rheumatologic Diseases

Cardiovascular disease risk is evident during childhood for patients with juvenile systemic lupus erythematosus, juvenile dermatomyositis, and juvenile idiopathic arthritis. The American Heart Association defines cardiovascular health as a positive health construct reflecting the sum of protective factors against cardiovascular disease. Disease-related factors such as chronic inflammation and endothelial dysfunction increase cardiovascular disease risk directly and through bidirectional relationships with poor cardiovascular health factors. Pharmacologic and nonpharmacologic interventions to improve cardiovascular health and long-term cardiovascular outcomes in children with rheumatic disease are needed.

Relationship of Gensini score with retinal vessel diameter and arteriovenous ratio in senile CHD

Background

This study aimed to find the correlation of Gensini score with retinal vessel diameter and arteriovenous ratio in elderly patients with coronary heart disease (CHD).

Methods

This study included 120 senile CHD patients as the CHD group and 100 healthy individuals as the normal group (NG). Gensini score was used to evaluate the severity of coronary artery lesions. Central retinal artery equivalents (CRAE), central retinal venular equivalents (CRVE), and arteriovenous ratio (AVR) were measured.

Results

CHD group has lower CRAE and AVR than NG, while higher CRVE was observed in NG. CRAE and AVR in UAP (unstable angina pectoris) and AMI (acute myocardial infarction) groups showed reduction (stable angina pectoris); however, enhanced CRVE and Gensini scores in UA and AMI groups were observed as compared to the SAP group. CRAE and AVR in moderate and severe groups were reduced to a greater extent compared to the mild groups, while enhanced CRVE and Gensini scores were observed more often in the severe group than the mild group. CRAE and AVR were negatively correlated with the Gensini score; however, CRVE was positively correlated with the Gensini score.

Conclusion

AVR is expected to be a noninvasive index to diagnose and predict senile CHD, which has a certain evaluation value. Diabetes, smoking history, and TC are independent risk factors of senile CHD.

The impact of antimalarial agents on traditional and non-traditional subclinical atherosclerosis biomarkers in systemic lupus erythematosus: A systematic review and meta-analysis

OBJECTIVE

Cardiovascular (CV) morbidity is a well-established problem in systemic lupus erythematosus (SLE). Antimalarial (AM) therapy has been seen as a potential atheroprotective agent. The aim was to assess the impact of AM therapy on traditional and novel atherosclerosis (AT) biomarkers in patients with SLE.

METHODS

A search of MEDLINE, EMbase, and Cochrane library for studies evaluating the impact of AM on AT biomarkers in SLE was conducted. Data extraction included serum, functional and structural traditional and novel biomarkers. A narrative synthesis of the findings and a meta-analysis with random effects was conducted estimating mean differences (MD), OR, HR and 95% CIs.

RESULTS

The search strategy produced 148 articles, of which 64 were extracted for analysis. The MD in VLDL-cholesterol (-10.29, 95% CI -15.35, 5.24), triglycerides (-15.68, 95% CI -27.51, -3.86), and diastolic BP (-3.42, 95% CI -5.62, -1.23) differed significantly in patients on AM therapy compared with those without AM therapy. Patients on AM had a lower prevalence and incidence of diabetes mellitus than patients not on AM (HR: 0.39, 95% CI 0.17, 0.88). HCQ use was associated with lower blood pressure (BP) variability. Structural markers like carotid intima-media thickness (IMT), carotid plaque (CP) and coronary artery calcification (CAC) were not influenced by AM. For functional markers like endothelial and arterial stiffness the benefit was unclear. The GRADE approach showed a very low-to-low quality of evidence (QoE) per outcome.

CONCLUSIONS

There is some evidence on the associations between AM therapy and some AT markers. However, the data on which this conclusion was based was of low to very low evidence.

Plasma osteopontin versus intima media thickness of the common carotid arteries in well-characterised patients with systemic lupus erythematosus

Objective

The progress of accelerated atherosclerosis in systemic lupus erythematosus (SLE) is incompletely understood. Circulating osteopontin (OPN) is increased in autoimmune conditions, e.g. SLE, and its serum concentration was recently reported to associate with subclinical atherosclerosis in SLE, as measured by carotid intima-media thickness. The aim of this study was to investigate whether OPN may be used as a surrogate biomarker of subclinical atherosclerosis in SLE patients with different disease phenotypes.

Methods

We recruited 60 well-characterised SLE cases and 60 age- and sex-matched healthy controls. The SLE cases were divided into three different disease phenotypes: SLE with antiphospholipid syndrome (APS), lupus nephritis, and isolated skin and joint involvement. Plasma OPN was detected by ELISA (Quantikine®, R&D Systems). Common carotid arteries intima media thickness was compared between the studied groups in relation to OPN levels and risk factors for vascular changes. Intima media thickness of common carotid arteries was measured by using a sensitive ultrasound technique (LOGIQ™ E9 ultrasound, GE Healthcare).

Results

OPN levels were significantly higher among the entire SLE group (n = 60) compared to the healthy controls (P = 0.03). SLE cases with concomitant APS (n = 20) showed higher OPN levels than the controls (P = 0.004), whereas none of the other two subgroups differed significantly from the healthy controls. OPN and intima media thickness were correlated to several traditional risk factors of atherosclerosis, as well as to SLE-related factors. Yet, no significant correlation was observed between OPN levels and ultrasound findings of the common carotid arteries.

Conclusions

In line with previous studies, we observed increased OPN levels among SLE patients as compared to matched controls. However, the OPN concentrations did not correlate with intima media thickness of the common carotid arteries. Based on our findings, the use of OPN as a surrogate biomarker of subclinical atherosclerosis in SLE subjects, regardless of clinical phenotypes, cannot be recommended.

Understanding Accelerated Atherosclerosis in Systemic Lupus Erythematosus: Toward Better Treatment and Prevention

Systemic lupus erythematosus (SLE) carries a significant risk of cardiovascular disease (CVD). The prevalence of premature CVD is especially noteworthy because it occurs in premenopausal women with SLE who would otherwise have very low rates of CVD. While traditional risk factors likely play a role in development of CVD in the setting of SLE, they do not fully explain the excess risk. The pathogenesis of CVD in SLE is not fully understood, but the inflammatory nature of SLE is believed to be a key factor in accelerating atherosclerosis. Systemic inflammation may lead to an abnormal lipid profile with elevated triglycerides, total cholesterol, and low-density lipoprotein cholesterol and dysfunctional high-density lipoprotein cholesterol. Additionally, the inflammatory milieu of SLE plasma promotes endothelial dysfunction and vascular injury, early steps in the progression of atherosclerotic CVD. Despite the overall headway that has been achieved in treating lupus, innovative therapeutics specifically targeting the progression of atherosclerosis within the lupus population are currently lacking. However, there have been advancements in the development of promising modalities for diagnosis of subclinical atherosclerosis and detection of high CVD risk patients. Due to the significant impact of CVD on morbidity and mortality, research addressing prevention and treatment of CVD in SLE needs to be prioritized. This review explores the intricate interplay of SLE-specific properties that contribute to atherosclerosis and CVD within this population, as well as screening methods and possible therapies.

Prevalence and treatment conditions for hypertension and dyslipidaemia complicated with systemic lupus erythematosus: A multi-centre cross-sectional study

OBJECTIVE

This study aimed to assess the prevalence and actual treatment conditions for hypertension and dyslipidaemia complicated with systemic lupus erythematosus (SLE).

METHODS

This was a cross-sectional study. We established the lupus registry of nationwide institutions (LUNA), a multi-centre cohort of SLE patients in Japan. From February 2016 to July 2018, 597 SLE patients were registered in the LUNA. We evaluated the incidence of hypertension and dyslipidaemia and analysed the risk factors for hypertension and dyslipidaemia by logistic regression analysis.

RESULTS

Overall, 597 patients were enrolled in the study. The median age was 44 years, and 88.0% of the patients were female. Among all the patients, 92.9% used prednisolone. The prevalence of hypertension and dyslipidaemia was 43.9% and 54.7%, respectively. Among the patients receiving medication for hypertension, 24.7% exhibited insufficient control (systolic blood pressure >140 mmHg or diastolic blood pressure >90 mmHg), and among those receiving medication for hyperlipidaemia, 48.1% showed insufficient control (low-density lipoprotein cholesterol >140 mg/dL or triglyceride >150 mg/dL). The risk factors for hypertension were age, body mass index (BMI), disease duration, past maximum dose of prednisolone, and renal involvement, whereas those for dyslipidaemia were age and BMI.

CONCLUSION

About half of the patients had hypertension or dyslipidaemia, and a considerable number of cases were poorly controlled despite medication. Our data suggest that physicians should treat SLE activity as well as its complications, especially the common risk factors for atherosclerosis.

The Use of Glucocorticoids in Lupus Nephritis: New Pathways for an Old Drug

Glucocorticoids therapy has greatly improved the outcome of lupus nephritis patients. Since their discovery, their adverse effects have counterbalanced their beneficial anti-inflammatory effects. Glucocorticoids exert their effects through both genomic and non-genomic pathways. Differential activation of these pathways is clinically relevant in terms of benefit and adverse effects. Ongoing aims in lupus nephritis treatment development focus on a better use of glucocorticoids combined with immunosuppressant drugs and biologics. Newer regimens aim to decrease the peak glucocorticoid dose, allow a rapid glucocorticoid tapering, and intend to control disease activity with a lower cumulative glucocorticoid exposure. In this review we discuss the mechanisms, adverse effects and recent strategies to limit glucocorticoid exposure without compromising treatment efficacy.

Patients with SLE have higher risk of cardiovascular events and mortality in comparison with controls with the same levels of traditional risk factors and intima-media measures, which is related to accumulated disease damage and antiphospholipid syndrome: a case-control study over 10 years

OBJECTIVE

SLE is a strong risk factor for premature cardiovascular (CV) disease and mortality. We investigated which factors could explain poor prognosis in SLE compared with controls.

METHODS

Patients with SLE and population controls without history of clinical CV events who performed carotid ultrasound examination were recruited for this study. The outcome was incident CV event and death. Event-free survival rates were compared using Kaplan-Meier curves. Relative HR (95% CI) was used to estimate risk of outcome.

RESULTS

Patients (n=99, 87% female), aged 47 (13) years and with a disease duration of 12 (9) years, had mild disease at inclusion, Systemic Lupus Erythematosus Diseases Activity Index score of 3 (1-6) and Systemic Lupus International Collaborating Clinics (SLICC) Damage Index score of 0 (0-1). The controls (n=109, 91% female) were 49 (12) years old. Baseline carotid intima-media thickness (cIMT) did not differ between the groups, but plaques were more prevalent in patients (p=0.068). During 10.1 (9.8-10.2) years, 12 patients and 4 controls reached the outcome (p=0.022). Compared with the controls, the risk of the adverse outcome in patients increased threefold to fourfold taking into account age, gender, history of smoking and diabetes, family history of CV, baseline body mass index, waist circumference, C reactive protein, total cholesterol, high-density lipoprotein, low-density lipoprotein, dyslipidaemia, cIMT and presence of carotid plaque. In patients, higher SLICC score and SLE-antiphospholipid syndrome (SLE-APS) were associated with increased risk of the adverse outcome, with respective HRs of 1.66 (95% CI 1.20 to 2.28) and 9.08 (95% CI 2.71 to 30.5), as was cIMT with an HR of 1.006 (95% CI 1.002 to 1.01). The combination of SLICC and SLE-APS with cIMT significantly improved prediction of the adverse outcome (p<0.001).

CONCLUSION

In patients with mild SLE of more than 10 years duration, there is a threefold to fourfold increased risk of CV events and death compared with persons who do not have SLE with similar pattern of traditional CV risk factors, cIMT and presence of carotid plaque. SLICC, SLE-APS and subclinical atherosclerosis may indicate a group at risk of worse outcome in SLE.

Biomarker profiles of endothelial activation and dysfunction in rare systemic autoimmune diseases: implications for cardiovascular risk

OBJECTIVES

Vasculopathy is an important hallmark of systemic chronic inflammatory connective tissue diseases (CICTD) and is associated with increased cardiovascular risk. We investigated disease-specific biomarker profiles associated with endothelial dysfunction, angiogenic homeostasis and (tissue) inflammation, and their relation to disease activity in rare CICTD.

METHODS

A total of 38 serum proteins associated with endothelial (dys)function and inflammation were measured by multiplex-immunoassay in treatment-naive patients with localized scleroderma (LoS, 30), eosinophilic fasciitis (EF, 8) or (juvenile) dermatomyositis (34), 119 (follow-up) samples during treatment, and 65 controls. Data were analysed by unsupervised clustering, Spearman correlations, non-parametric t test and ANOVA.

RESULTS

The systemic CICTD, EF and dermatomyositis, had distinct biomarker profiles, with 'signature' markers galectin-9 (dermatomyositis) and CCL4, CCL18, CXCL9, fetuin, fibronectin, galectin-1 and TSP-1 (EF). In LoS, CCL18, CXCL9 and CXCL10 were subtly increased. Furthermore, dermatomyositis and EF shared upregulation of markers related to interferon (CCL2, CXCL10), endothelial activation (VCAM-1), inhibition of angiogenesis (angiopoietin-2, sVEGFR-1) and inflammation/leucocyte chemo-attraction (CCL19, CXCL13, IL-18, YKL-40), as well as disturbance of the Angiopoietin-Tie receptor system and VEGF-VEGFR system. These profiles were related to disease activity, and largely normalized during treatment. However, a subgroup of CICTD patients showed continued elevation of CXCL10, CXCL13, galectin-9, IL-18, TNFR2, VCAM-1, and/or YKL-40 during clinically inactive disease, possibly indicating subclinical interferon-driven inflammation and/or endothelial dysfunction.

CONCLUSION

CICTD-specific biomarker profiles revealed an anti-angiogenic, interferon-driven environment during active disease, with incomplete normalization under treatment. This warrants further investigation into monitoring of vascular biomarkers during clinical follow-up, or targeted interventions to minimize cardiovascular risk in the long term.

Effect of Leptin on Chronic Inflammatory Disorders: Insights to Therapeutic Target to Prevent Further Cardiovascular Complication

In response to obesity-associated chronic inflammatory disorders, adipose tissue releases a biologically active peptide known as leptin. Leptin activates the secretion of chemical mediators, which contribute to the pathogenesis of chronic inflammatory disorders, such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and psoriasis. Conversely, adiposity and obesity are the major aggravating risk factors in the pathogenesis of metabolic syndrome (MetS), including type II diabetes mellitus and obesity-associated hypertension. Elevated level of leptin in obesity-associated hypertension causes an increase in the production of aldosterone, which also results in elevation of arterial blood pressure. Hyperleptinemia is associated with the progress of the atherosclerosis through secretion of pro-inflammatory cytokines, like interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), IL-17, and other cytokines to promote inflammation. The release of those cytokines leads to chronic inflammatory disorders and obesity-associated MetS. Thus, the aberrant leptin level in both MetS and chronic inflammatory disorders also leads to the complication of cardiovascular diseases (CVD). Therapeutic target of leptin regarding its pro-inflammatory effect and dysregulated sympathetic nervous system activity may prevent further cardiovascular complication. This review mainly assesses the mechanism of leptin on the pathogenesis and further cardiovascular risk complication of chronic inflammatory disorders.

Quality of care for patients with SLE: data from the American College of Rheumatology's RISE registry

OBJECTIVE

Although multiple national quality measures focus on the management and safety of rheumatoid arthritis, few measures address the care of patients with SLE. We applied a group of quality measures relevant to the care of SLE patients and used the ACR's RISE registry to assess nationwide variations in care.

METHODS

Data derived from RISE and included patients with ≥2 visits with SLE codes ≥30 days apart in 2017-2018. We calculated performance on 5 quality measures: renal disease screening; blood pressure assessment and management; hydroxychloroquine (HCQ) prescribing; safe dosing for HCQ; and prolonged glucocorticoid use at doses > 7.5 mg/day. We reported performance on these measures at the practice level. We used logistic regression to assess independent predictors of performance after adjusting for sociodemographic and utilization factors.

RESULTS

We included 27,567 unique patients from 186 practices; 91.7% were female, 48% white, with mean age 53.5±15.2 years. Few patients had adequate screening for the development of renal manifestations (39.5%). Although blood pressure assessment was common (94.4%), a meaningful fraction had untreated hypertension (17.7%). Many received HCQ (71.5%), but only 62% at doses ≤ 5.0 mg/kg/day. Some received at least moderate-dose steroids for ≥ 90 days (18.5%). We observed significant practice variation on every measure.

CONCLUSION

We found potential gaps in care for patients with SLE across the U.S. Although some performance variation may be explained by differences in disease severity, dramatic differences suggest that developing quality measures to address important health care processes in SLE may improve care.

Accrual of Atherosclerotic Vascular Events in a Multicenter Inception Systemic Lupus Erythematosus Cohort

OBJECTIVE

In previous studies, atherosclerotic vascular events (AVEs) were shown to occur in ~10% of patients with systemic lupus erythematosus (SLE). We undertook this study to investigate the annual occurrence and potential risk factors for AVEs in a multinational, multiethnic inception cohort of patients with SLE.

METHODS

A large 33-center cohort of SLE patients was followed up yearly between 1999 and 2017. AVEs were attributed to atherosclerosis based on SLE being inactive at the time of the AVE as well as typical atherosclerotic changes observed on imaging or pathology reports and/or evidence of atherosclerosis elsewhere. Analyses included descriptive statistics, rate of AVEs per 1,000 patient-years, and univariable and multivariable relative risk regression models.

RESULTS

Of the 1,848 patients enrolled in the cohort, 1,710 had ≥1 follow-up visit after enrollment, for a total of 13,666 patient-years. Of these 1,710 patients, 3.6% had ≥1 AVEs attributed to atherosclerosis, for an event rate of 4.6 per 1,000 patient-years. In multivariable analyses, lower AVE rates were associated with antimalarial treatment (hazard ratio [HR] 0.54 [95% confidence interval (95% CI) 0.32-0.91]), while higher AVE rates were associated with any prior vascular event (HR 4.00 [95% CI 1.55-10.30]) and a body mass index of >40 kg/m² (HR 2.74 [95% CI 1.04-7.18]). A prior AVE increased the risk of subsequent AVEs (HR 5.42 [95% CI 3.17-9.27], P < 0.001).

CONCLUSION

The prevalence of AVEs and the rate of AVE accrual demonstrated in the present study is much lower than that seen in previously published data. This may be related to better control of both the disease activity and classic risk factors.

Cardiovascular risk in patients with plaque psoriasis and psoriatic arthritis without a clinically overt cardiovascular disease: the role of endothelial progenitor cells

Psoriasis is an autoimmune, chronic disease determined by environmental and genetic factors. The occurrence of psoriasis is accompanied by metabolic diseases, cardiovascular diseases (CVD) and depression, disturbances on interpersonal interactions and a tendency towards social isolation. Regardless of the form of psoriasis and the severity of the disease, early arterial lesions are recorded in arterial vessels of patients. Nevertheless, the chance of CVD is higher in the population of patients with severe psoriasis than in patients with mild to moderate psoriasis. The correlation between the presence of atherosclerotic plaque and psoriatic plaque is partially explained by: (1) a similar inflammatory pathway – via the T helper cells, (2) impaired angiogenesis, and (3) endothelial dysfunction. In the considered tests, the diagnostic tools used showed a reduced level of endothelial progenitor cells in the circulation of patients with psoriasis. Endogenous angiopoietin stimulation in patients with psoriasis leads to deterioration of endothelial regeneration, atherosclerosis which secondarily contributes to the progression of heart failure. Clinical and experimental data confirm the potential of immunomodulatory methods to combat both autoimmune and cardiovascular diseases through the use of immunosuppressive drugs. Full understanding of the way in which CVD develops in patients with autoimmune diseases would enable the implementation of targeted cell therapy allowing the quality and life expectancy of patients to be improved. Modern cellular diagnostic tools allow the use of highly specific biomarkers, which in the near future will enable a reduction in morbidity and mortality due to CVD.

Seventy years after Hench’s Nobel prize: revisiting the use of glucocorticoids in systemic lupus erythematosus

In 1950, Hench, Kendall and Reichstein were awarded with the Nobel Prize in Physiology and Medicine for the isolation and first therapeutic use of glucocorticoids. Since then, they have become one of the main agents in the treatment of systemic lupus erythematosus (SLE). The use of high-dose oral glucocorticoids (usually 1 mg/kg/day of prednisone equivalent) have become the rule for treating moderate to severe lupus activity. In addition, tapering schemes have not been well defined, all this leading to prolonged exposures to potentially damaging amounts of glucocorticoids. Several studies have shown that glucocorticoids are a major cause of toxicity in SLE in a dose-dependent manner, with prolonged doses greater than 7.5 mg/day being associated with damage accrual. Thus, there is an urgent need for different therapeutic schedules that can achieve a rapid and durable control of lupus activity while reducing the many unwanted effects of glucocorticoids. Recent data show that pulses of methyl-prednisolone are an effective first-line therapy to treat lupus flares (not only severe ones) without major short or long-term toxicity and allowing a reduction in oral prednisone doses. Universal use of hydroxychloroquine – always recommended, infrequently accomplished – and early therapy with immunosuppressive drugs also help control SLE and reduce prednisone load. Results from observational studies confirm the more rapid achievement of remission and the reduction of long-term damage using these combination schedules with reduced prednisone doses. Seventy years after their first therapeutic use, we are learning to use glucocorticoids in a more efficient and safe manner.

Impact of the new American College of Cardiology/American Heart Association definition of hypertension on atherosclerotic vascular events in systemic lupus erythematosus

Background

The 2017 American College of Cardiology/American Heart Association guidelines defined hypertension at ≥130/80 mm Hg. Studies on patients with connective tissue diseases were not considered. Our aim was to assess the impact of this definition on atherosclerotic vascular events (AVEs) in systemic lupus erythematosus.

Patients methods

Individuals from the Toronto Lupus Clinic with at least 2 years of follow-up and no prior AVE were divided in three groups according to their mean blood pressure (BP) over that period (≥140/90 mm Hg, 130-139/80-89 mm Hg and <130/80 mm Hg). They were followed until the first occurrence of an AVE (fatal or non-fatal coronary artery disease, cerebrovascular event and peripheral vascular disease) or last visit. Groups were compared as per the baseline atherosclerotic risk factors. A multivariable time-dependent analysis was performed to adjust for the presence of other risk factors.

Results

Of 1532 patients satisfying the inclusion criteria, 155 (10.1%) had a BP ≥140/90 mm Hg, 316 (20.6%) 130–139/80–89 mm Hg and 1061 (69.3%) were normotensives. After a mean follow-up of 10.8 years, 124 AVEs were documented. The incidence rates were 18.9, 11.5 and 4.5 per 1000 patient-years for the three groups, respectively (p=0.0007 between the 130–139/80–89 mm Hg group and the normotensives). A mean BP of 130–139/80–89 mm Hg over the first 2 years was independently associated with the occurrence of AVEs (HR 1.73, 95% CI 1.13 to 2.65, p=0.011).

Conclusion

Patients with lupus with a sustained mean BP of 130–139/80–89 mm Hg over 2 years had a significantly higher incidence of AVEs compared with normotensive individuals. This BP level should be the target for antihypertensive therapy to minimise their cardiovascular risk.

Similar progression of carotid intima-media thickness in 7-year surveillance of patients with mild SLE and controls, but this progression is still promoted by dyslipidaemia, lower HDL levels, hypertension, history of lupus nephritis and a higher prednisolone usage in patients

Objective

To compare progression of subclinical atherosclerosis and factors promoting it in patients with SLE and controls.

Methods

Consecutive patients with SLE and age-matched, sex-matched population controls from the SLEVIC cohort were assessed at inclusion and after 7 years with standardised data collection and carotid ultrasound. Effect of risk factors on carotid intima-media thickness (cIMT) progression was examined with adjusted linear mixed models.

Results

A total of 77 patients and 74 controls, 68% and 61% of the original cohort, completed follow-up. The patients were (mean) 47 years old, 90% were women, and controls were 51 years old, 92% women. Patients had disease duration of (mean) 11 years, mild disease activity and low severity at both assessments. Baseline cIMT did not differ between the groups. An average absolute cIMT progression was 0.009 mm/year in patients and 0.011 mm/year in controls, intergroup difference p=0.9.Of factors at inclusion, dyslipidaemia, lower levels of high-density lipoprotein (HDL) and carotid plaque in patients and controls, and higher systolic blood pressure, total cholesterol:HDL and LDL:HDL ratios and triglycerides in patients were associated with cIMT progression. Of factors at follow-up, hypertension and blood lipids in patients and HDL in controls were significantly associated with cIMT progression. History of lupus nephritis and a higher average dose of prednisolone used since diagnosis were associated with cIMT progression in patients. Associations of risk factors with cIMT progression were stronger in presence of plaques.

Conclusion

We observed a statistically comparable progression of cIMT in patients with mild SLE and controls over 7 years, which implies that progression of subclinical atherosclerosis in some patients with SLE could follow that of the general population. Traditional cardiovascular (CV) risk factors, history of lupus nephritis and higher use of corticosteroids promote cIMT progression in SLE. Detection of carotid plaque may add to CV risk stratification.

Investigation of the Association Between Carotid Artery Intima-Media Thickness (IMT) and Cardiac Risk Factors in Patients with Systemic Lupus Erythematosus

BACKGROUND

The relationship between SLE and traditional risk factors for cardiovascular events was evaluated.

METHODS

The data regarding sixty patients with SLE and 30 healthy controls (age and sex matched) were gathered using SLEDAI forms. Venous blood (10mL) from all the participants was examined for hs-CRP, homocysteine, VCAM1, CBC, anti-DNA antibody, C3, C4, low-density lipoprotein (LDL), cholesterol, FBS and triglyceride. The IMT of carotid arteries was determined bilaterally by ultrasound. Other measurements included insulin levels via Elisa (Linco/Millipore Corp) and the HOMA-IR index for insulin resistance.

RESULTS

The mean age (in years) in the test and control groups was 28.8±10.3 (18-52) and 33.8±9.13 (18-48), respectively. The average IMT in the test group was directly related to serum levels of VCAM1 (p<0.001), homocysteine (p<0.001), cholesterol (p<0.009), LDL (p<0.001), TG (p<0.001), and FPG (p=0.004). The association between other risk factors, insulin resistance, carotid IMT and SLEDAI, was nonexistent. Mean insulin and insulin resistance levels in all the participants were 0.43±2.06 µU/mL and 0.09±0.44, respectively. There was no significant difference between the test and control groups regarding serum insulin and insulin resistance levels (p=0.42 and p=0.9, respectively). None of the risk factors, such as hsCRP, VCAM1, or homocysteine, were shown to be related to insulin resistance (p=0.6, p=0.6, p=0.09, respectively).

CONCLUSION

Our findings did not show an increase in the prevalence of atherosclerosis in patients with SLE. There was no association between IMT and insulin resistance. However, the former was associated with FPG, total cholesterol, LDL, TG, homocystein and VCAM1.

Altered body composition and increased visceral adipose tissue in premenopausal and late postmenopausal patients with SLE

OBJECTIVE

Visceral adipose tissue (VAT) is becoming a recognized cardiovascular (CV) risk factor. This study aimed to evaluate body composition, especially VAT, in systemic lupus erythematosus (SLE) and to explore the association between VAT and SLE disease-related factors.

METHOD

Ninety-eight inpatients with SLE and 108 age- and body mass index (BMI)-matched healthy controls were included. Demographic and clinical parameters were recorded. The VAT was measured by dual-energy x-ray absorptiometry.

RESULT

The mean age and disease duration of patients were 46.4 ± 13.0 years and 8.0 ± 7.0 years, respectively. Patients with SLE had higher VAT volume (p = 0.0015) and mass (p = 0.0017) than controls, especially in premenopausal and postmenopausal groups. The subanalysis of subjects with BMI less than 25 kg/m² indicated that patients had lower lean mass (p = 0.0005), fat-free mass (p = 0.0005), and fat-free mass index (p = 0.0001), but increased adiposity distribution than controls, including VAT volume and mass. However, overweight/obese patients had similar body composition with controls. The VAT volume correlated with BMI, age, menopausal status, hypertension, uric acid, creatinine, non-high-density lipoprotein cholesterol, and triglyceride in both groups. In the patient group, the VAT volume correlated with disease duration, Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR-DI), and low serum complement, but not with SLEDAI and glucocorticoid dose.

CONCLUSION

This study suggested that SLE patients had some traditional CV risk factors such as altered body composition and increased VAT. The higher VAT in patients with SLE was associated with traditional cardiometabolic risks, which may contribute to CV events in SLE populations. Key Points • Patients with SLE had increased VAT volume and mass than controls. • The VAT volume correlated with traditional cardiometabolic risk factors. • In SLE patient group, the VAT volume correlated with disease duration, SLICC/ACR-DI, and low serum complementC3/C4, but not with SLEDAI and glucocorticoid dose.

Body mass index and glucocorticoid dose contribute to subclinical atherosclerosis in Korean patients with systemic lupus erythematosus: A prospective 4 year follow-up study

AIM

Patients with systemic lupus erythematosus (SLE) have an increased risk of cardiovascular disease owing to an immunological abnormality, along with traditional risk factors. We found that carotid artery intima-media thickness (cIMT) and plaque were associated with age, body mass index (BMI) and disease activity in a previous study 4 years ago. Our aim was to identify risk factors associated with progression of subclinical atherosclerosis in SLE.

METHODS

We assessed cIMT and plaque using Doppler ultrasonography in 61 Korean women with SLE who were enrolled in the previous study 4 years ago.

RESULTS

The mean cIMT of the patients was 0.39 ± 0.09 mm; 11 patients had carotid plaques, which was similar to the results of the previous study. Twenty-one patients had increased cIMT, and new carotid plaque had developed in seven patients. Patients with increased cIMT had a lower BMI and took fewer non-steroidal anti-inflammatory drugs and higher 4 year cumulative glucocorticoid dose than patients without increased cIMT. The 4 year cumulative glucocorticoid dose was higher in patients with carotid plaque than in those without. On multivariate regression analysis, BMI (odds ratio [OR] = 0.67, P = 0.034) was associated with increased cIMT, and the 4 year cumulative glucocorticoid dose was associated with increased cIMT (OR = 6.994, P = 0.025) and carotid plaque (OR = 5.651, P = 0.031).

CONCLUSION

This prospective follow-up study on cIMT and plaque in patients with SLE showed that low BMI and 4 year cumulative glucocorticoid dose were associated with the progression of subclinical atherosclerosis.

Relationship between Neutrophil-to-Lymphocyte Ratio and Pulse Wave Velocity in Young Patients with Systemic Lupus Erythematosus

Background:

The incidence of atherosclerosis-related myocardial infarction can be as much as 50-fold greater in young patients with systemic lupus erythematosus (SLE) than in age-matched controls. There are several explanations for this phenomenon, all of which result in a chronic state of low-grade inflammation. Recently, the neutrophil-to-lymphocyte ratio (NLR) has been proposed as a useful biomarker of inflammation. Pulse wave velocity (PWV) is a reliable indicator of vascular damage and atherosclerosis. There is a paucity of data concerning the relationship between NLR and atherosclerosis as measured by PWV in patients with SLE. This study aimed to verify whether there is a positive correlation between NLR and PWV and to explore factors that influence PWV in young SLE patients.

Methods:

A total of 90 female patients with SLE were enrolled in this cross-sectional investigation. Traditional and nontraditional cardiovascular risk factors were assessed on the same day that brachial-ankle PWV (baPWV) was examined. The patients were divided into three groups according to their mean baPWV values: patients whose mean baPWV value was lower than the first tertile were placed in Group 1; patients whose mean baPWV value was between the first tertile and the second tertile were placed in Group 2; and patients whose mean baPWV value was higher than the second tertile were placed in Group 3. SPSS 20.0 was used to perform all statistical analyses in this study. Both univariate linear regression and multivariate regression models were utilized to analyze the association between NLR and arterial stiffness.

Results:

Systolic blood pressure, diastolic blood pressure (DBP), and triglycerides were all significantly different among Groups 1, 2, and 3 (111.90 ± 12.85 mmHg vs. 114.60 ± 12.88 mmHg vs. 129.43 ± 16.21 mmHg, P < 0.001; 68.77 ± 8.63 mmHg vs. 71.87 ± 9.77 mmHg vs. 82.57 ± 14.89 mmHg, P < 0.001; and 1.44 [0.91–2.47] mmol/L vs. 0.98 [0.78–1.26] mmol/L vs. 2.20 [0.94–3.66] mmol/L, P = 0.030; respectively), as were creatinine (57.50 [52.00–69.00] μmol/L vs. 55.50 [49.00–64.00] μmol/L vs. 64.00 [56.00–86.00] μmol/L, P = 0.045) and blood urea nitrogen (4.27 [3.79–6.22] mmol/L vs. 4.16 [3.47–4.84] mmol/L vs. 5.88 [4.04–8.19] mmol/L, P = 0.011). NLRs were significantly different among Groups 1, 2, and 3 (2.16 [1.56–3.42] vs. 3.12 [1.91–4.19] vs. 5.29 [2.63–7.25], P = 0.001). NLR, together with DBP and the SLE disease activity index, independently predicts PWV.

Conclusions:

This study demonstrated that there was a positive correlation between NLR and PWV. Moreover, we found that disease activity and DBP were also positively correlated with PWV.

Long-Term Clinical Outcomes in a Cohort of Adults With Childhood-Onset Systemic Lupus Erythematosus

OBJECTIVE

Childhood-onset systemic lupus erythematosus (SLE) is a severe, lifelong, multisystem autoimmune disease. Long-term outcome data are limited. This study was undertaken to identify clinical characteristics and health-related quality of life (HRQoL) of adults with childhood-onset SLE.

METHODS

Patients participated in a single study visit comprising a structured history and physical examination. Disease activity (scored using the SLE Disease Activity Index 2000 [SLEDAI-2K]), damage (scored using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index [SDI]), and HRQoL (scored using the Short Form 36 Health Survey) were assessed. Medical records were reviewed.

RESULTS

In total, 111 childhood-onset SLE patients were included; the median disease duration was 20 years, 91% of patients were female, and 72% were white. Disease activity was low (median SLEDAI-2K score 4), and 71% of patients received prednisone, hydroxychloroquine (HCQ), and/or other disease-modifying antirheumatic drugs. The vast majority of new childhood-onset SLE-related manifestations developed within 2 years of diagnosis. Damage such as myocardial infarctions began occurring after 5 years. Most patients (62%) experienced damage, predominantly in the musculoskeletal, neuropsychiatric, and renal systems. Cerebrovascular accidents, renal transplants, replacement arthroplasties, and myocardial infarctions typically occurred at a young age (median age 20 years, 24 years, 34 years, and 39 years, respectively). Multivariate logistic regression analysis showed that damage accrual was associated with disease duration (odds ratio [OR] 1.15, P < 0.001), antiphospholipid antibody positivity (OR 3.56, P = 0.026), and hypertension (OR 3.21, P = 0.043). Current HCQ monotherapy was associated with an SDI score of 0 (OR 0.16, P = 0.009). In this cohort, HRQoL was impaired compared to the overall Dutch population. The presence of damage reduced HRQoL scores in 1 domain. High disease activity (SLEDAI-2K score ≥8) and changes in physical appearance strongly reduced HRQoL scores (in 4 of 8 domains and 7 of 8 domains, respectively).

CONCLUSION

The majority of adults with childhood-onset SLE in this large cohort developed significant damage at a young age and had impaired HRQoL without achieving drug-free remission, illustrating the substantial impact of childhood-onset SLE on future life.

Atherosclerotic Vascular Events in Systemic Lupus Erythematosus: An Evolving Story

OBJECTIVE

Atherosclerotic vascular events (AVE) are a major cause of mortality and morbidity in systemic lupus erythematosus (SLE). We aimed to determine the effect of early recognition and therapy for both classic risk factors for AVE and for SLE, on the burden of AVE in SLE in recent decades.

METHODS

Inception patients who entered the University of Toronto Lupus Clinic between 1975 and 1987 followed to 1992 (Cohort 1), and between 1999 and 2011 followed to 2016 (Cohort 2) were studied. AVE attributed to atherosclerosis and occurring during the 17 years were identified. SLE disease activity and therapy as well as hypertension, hypercholesterolemia, hyperglycemia, and smoking were assessed. Analysis included descriptive statistics on baseline characteristics, traditional risk factors over the followup, outcome rates by each 100 person-years (PY), Kaplan-Meier cumulative AVE curves, as well as competing risk Cox models adjusted by inverse probability weights.

RESULTS

Of the 234 patients in Cohort 1, 26 patients (11%) had an AVE compared with 10 of 262 patients (3.8%) in Cohort 2. The rate per 100 PY of followup was 1.8 in Cohort 1 and 0.44 in Cohort 2 (p < 0.0001). Better control of all risk factors and disease activity was achieved in Cohort 2. There was a reduction of 60% in the risk for AVE in Cohort 2.

CONCLUSION

The incidence of AVE in SLE in the modern era has declined in large part owing to more effective management of classic coronary artery risk factors and of SLE.

Acute Myocardial Infarction Outcomes in Systemic Lupus Erythematosus (from the Nationwide Inpatient Sample)

One of the major causes of mortality in systemic lupus erythematosus (SLE) is acute myocardial infarction. Whether in-hospital outcomes and management of ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) are different in SLE patients compared with those without SLE from large, recent dataset is unclear. We queried the Nationwide Inpatient Database from 2005 to 2014 and identified STEMI and NSTEMI admissions with and without SLE. The primary outcome was in-hospital mortality. Secondary outcomes were revascularization strategy (percutaneous coronary intervention, coronary artery bypass surgery, or thrombolytics), medical therapy rates (no reperfusion), and major adverse clinical events. A propensity-matched cohort was created to compare these outcomes. Odds ratio (OR) was calculated from the propensity-matched cohort. A total of 321,048 STEMI admissions, of which 1,001 (0.31%) and 572,971 NSTEMI admissions, of which 2,134 (0.37%) were SLE, were identified. In those with STEMI, 882 SLE and non-SLE admissions were propensity-matched. In-hospital mortality (9.1% vs 11.8%, OR 0.75, p = 0.07), revascularization strategy, medical therapy rates, and major adverse events were similar. Similarly, in those with NSTEMI, 1,770 SLE and 1,775 non-SLE were matched. In-hospital mortality (4.1% vs 4.50%, OR 0.90, p = 0.51), coronary artery bypass surgery, medical therapy rates, and major adverse events were mostly similar but the rate of percutaneous coronary intervention was higher in SLE (32.9% vs 29.6%, OR 1.16, p = 0.04). For both STEMI and NSTEMI, hospital cost and length of stay were similar between SLE and non-SLE cohorts. From a large administrative database in the United States, revascularization strategies and in-hospital outcomes of acute coronary syndrome were mostly similar between SLE and non-SLE.

Systemic lupus erythematosus: state of the art on clinical practice guidelines

Systemic lupus erythematosus (SLE) is the paradigm of systemic autoimmune diseases characterised by a wide spectrum of clinical manifestations with an unpredictable relapsing-remitting course. The aim of the present work was to identify current available clinical practice guidelines (CPGs) for SLE, to provide their review and to identify physicians’ and patients’ unmet needs. Twenty-three original guidelines published between 2004 and 2017 were identified. Many aspects of disease management are covered, including global disease management, lupus nephritis and neuropsychiatric involvement, management of pregnancies, vaccinations and comorbidities monitoring. Unmet needs relate with disease management of some clinical manifestations and adherence to treatment. Many patient’s unmet needs have been identified starting with faster diagnosis, need for more therapeutic options, guidelines on lifestyle issues, attention to quality of life and adequate education.

Canadian Rheumatology Association Recommendations for the Assessment and Monitoring of Systemic Lupus Erythematosus

OBJECTIVE

To develop recommendations for the assessment of people with systemic lupus erythematosus (SLE) in Canada.

METHODS

Recommendations were developed using the GRADE (Grading of Recommendations Assessment, Development, and Evaluation) approach. The Canadian SLE Working Group (panel of Canadian rheumatologists and a patient representative from Canadian Arthritis Patient Alliance) was created. Questions for recommendation development were identified based on the results of a previous survey of SLE practice patterns of members of the Canadian Rheumatology Association. Systematic literature reviews of randomized trials and observational studies were conducted. Evidence to Decision tables were prepared and presented to the panel at 2 face-to-face meetings and online.

RESULTS

There are 15 recommendations for assessing and monitoring SLE, with varying applicability to adult and pediatric patients. Three recommendations focus on diagnosis, disease activity, and damage assessment, suggesting the use of a validated disease activity score per visit and annual damage score. Strong recommendations were made for cardiovascular risk assessment and measuring anti-Ro and anti-La antibodies in the peripartum period and conditional recommendations for osteoporosis and osteonecrosis. Two conditional recommendations were made for peripartum assessments, 1 for cervical cancer screening and 2 for hepatitis B and C screening. A strong recommendation was made for annual influenza vaccination.

CONCLUSION

These are considered the first guidelines using the GRADE method for the monitoring of SLE. Existing evidence is largely of low to moderate quality, resulting in more conditional than strong recommendations. Additional rigorous studies and special attention to pediatric SLE populations and patient preferences are needed.

Risk of adverse events from different drugs for SLE: a systematic review and network meta-analysis

Objective

The comparative safety of immunosuppressive drugs, biologicals and glucocorticoids (GC) for patients with SLE remains controversial. We aimed to investigate the specific side effects of the available SLE drugs in this population of patients.

Methods

Electronic databases were systematically searched through September 2017 for randomised trials in patients with SLE. The primary outcomes were all-cause mortality and withdrawal related to adverse events (AEs). We performed a random-effects network meta-analysis to obtain estimates for primary and secondary outcomes and presented these estimates as ORs with 95% CIs.

Results

Forty-four studies comprising 9898 participants were included in the network meta-analysis. No drug regimen was considered to be safer for reducing all-cause mortality. However, compared with cyclophosphamide, azathioprine (OR 3.04, 95% CI (1.44 to 6.42)) and cyclosporine (OR 3.28, 95% CI (1.04 to 10.35)) were significantly less safety in AE-related withdrawals, and GC was ranked lowest and led to higher withdrawal rates. Tacrolimus (TAC) was ranked high and showed a benefit in many outcomes. Biologicals and chloroquine also showed good safety in all of the available outcomes, while the beneficial effects of other immunosuppressive drugs were not substantial in different types of serious adverse events.

Conclusions

TAC is the safest strategy for patients with SLE. Biologicals and chloroquine are also fairly safe for patients with SLE. The use of other immunosuppressive drugs and GC needs to be balanced against the potential harms of different types of AEs, and the practical safety of drug combinations still requires further trials to evaluate.

Novel Insights in Systemic Lupus Erythematosus and Atherosclerosis

Introduction

The systemic inflammatory nature of systemic lupus erythematosus (SLE) is well patent not only in the diverse clinical manifestations of the disease but also in the increased risk of premature atherosclerosis and cardiovascular events (CVE), making SLE one of the most complex diseases to study and manage in clinical practice.

Aim

To travel from old aspects to modern insights on the physiopathology, new molecular biomarkers, imaging methods of atherosclerosis assessment, and the potential treatments of atherosclerosis in SLE.

Methods

We conducted a literature search using PubMed database and performed a critical review.

Conclusion/discussion

Several developments have taken place in the understanding of the relationship between SLE and premature atherosclerosis. Nevertheless, cardiovascular diseases are still the major cause of reduced life expectancy in SLE and the main cause of death. The lack of standardization methods for the imaging assessment of atherosclerosis in SLE and the multifactorial nature of the disease are well patriated in the difficulty of achieving consistent and reproducible results among studies that focus in cardiovascular risk assessment and prediction. A raising number of molecular biomarkers of atherosclerosis have been proposed, but the combination of several biomarkers and risk factors may better estimate cardiovascular disease risk. Moreover, the development of effective therapies to prevent progression of atherosclerosis and CVE shall address systemic inflammation.

Increased risk of venous thromboembolism associated with polymyositis and dermatomyositis: a meta-analysis

Objective

Polymyositis and dermatomyositis (PM/DM) have been implicated in the development of venous thromboembolism (VTE). Previous studies investigating the association between PM/DM and VTE risk had yielded inconsistent findings. The aim of this study was to precisely estimate this association by meta-analysis of all available publications.

Methods

Two investigators independently performed a comprehensive literature search in databases of PubMed, Embase, and the Cochrane Library for eligible studies. The strength for the association was weighed by pooled odds ratios (ORs) with 95% confidence intervals (95% CIs). Stratified analysis and sensitivity analysis were performed for further analysis.

Results

Six studies including 9,045 patients with PM/DM were analyzed. The pooled OR suggested that inflammatory myositis was associated with increased risk of VTE (OR =4.31, 95% CI: 2.55–7.29, P<0.001). Besides, significantly elevated risk of VTE was related with PM and DM, respectively (for PM: OR =6.87, 95% CI: 4.12–11.46, P<0.001; for DM: OR =11.59, 95% CI: 6.54–20.55, P<0.001). In addition, inflammatory myositis could increase the risk of DVT (OR =4.85, 95% CI: 1.38–17.12, P<0.05) and PE (OR =4.74, 95% CI: 2.18–10.30, P<0.05). Sensitivity analysis did not materially alter the pooled results.

Conclusion

Our study shows strong evidence that patients with inflammatory myositis have an increased risk of VTE.

Assessment of subclinical atherosclerosis in systemic lupus erythematosus: A systematic review and meta-analysis

OBJECTIVES

To determine whether subclinical atherosclerosis is increased in patients with systemic lupus erythematosus (SLE) compared to healthy individuals, using carotid intima-media thickness (CIMT), carotid plaque (CP) presence or flow-mediated dilatation (FMD).

METHODS

A systematic literature search was performed using MedLine, Embase and Cochrane databases. Two reviewers independently screened the articles to identify studies that compared the rates of atherosclerosis in SLE patients versus healthy controls. The results were pooled in a meta-analysis. Factors influencing the CIMT, CP or FMD results were collected.

RESULTS

Of the 203 articles initially identified, 68 were selected for the meta-analysis. Compared to healthy controls, SLE patients had a significantly increased CIMT (mean difference [MD] of 0.08mm, 95% CI [0.06-0.09], P<0.05), more CP (odds ratio 2.01, 95% CI [1.63-2.47], P<0.05) and decreased FMD (MD -3.96%, 95% CI [-5.37 to -2.54)], P<0.05). There was marked heterogeneity among the studies. However, the results of the meta-analysis that included only the CIMT per new international recommendations also showed an increased CIMT in SLE patients, but the heterogeneity was low (MD 0.04mm, 95% CI [0.02-0.06], P<0.05; I²=23%).

CONCLUSION

SLE patients exhibit increased subclinical atherosclerosis compared to healthy controls. CIMT is a promising measure for cardiovascular risk evaluations because non-invasive, non-radiation-based, reproducible. Thus, CIMT can be proposed as an alternative to the reliable CP evaluation and to FMD, which is influenced by independent factors such as smoking. Future studies should focus on reducing the heterogeneity of these measures using standardized procedures.

Increased Risk of Multimorbidity in Patients With Sarcoidosis: A Population-Based Cohort Study 1976 to 2013

OBJECTIVE

To evaluate the risk and pattern of multimorbidity in patients with sarcoidosis.

PATIENTS AND METHODS

A cohort of all residents of Olmsted County, Minnesota, first diagnosed with sarcoidosis between January 1, 1976, and December 31, 2013, was identified through the medical record linkage system of the Rochester Epidemiology Project. Diagnosis was verified by individual medical record review. A cohort of sex- and age-matched comparators without sarcoidosis was assembled from the same population. Data on 18 chronic conditions recommended by the US Department of Health and Human Services for both cases and comparators were retrieved and compared.

RESULTS

The prevalence of multimorbidity (ie, the presence of ≥2 chronic conditions) was similar between the 2 groups: 111 of 345 cases (32.2%) and 110 of 345 comparators (31.9%) (P=.99). After the index date, 156 cases (43.8%) and 142 comparators (41.2%) developed multimorbidity, corresponding to a hazard ratio of 1.60 (95% CI, 1.27-2.01; P<.001). The cumulative incidence of the presence of ≥3, 4, and 5 chronic conditions was also consistently significantly higher in cases than in comparators (P value=.01, .004 and .002, respectively). Analysis by specific type of chronic condition revealed a significantly higher cumulative incidence of coronary artery disease, congestive heart failure, arrhythmia, stroke or transient ischemic attack, arthritis, depression, diabetes, and major osteoporotic fracture.

CONCLUSION

In this population, patients with sarcoidosis had a significantly higher risk of developing multimorbidity than did sex- and age-matched individuals without sarcoidosis.

Evolution of Risk Factors for Atherosclerotic Cardiovascular Events in Systemic Lupus Erythematosus: A Longterm Prospective Study

Objective.

We previously reported the effect of certain factors on cardiovascular disease (CVD) in 250 women with systemic lupus erythematosus (SLE) followed for 8 years. The aim of this study was to delineate their evolution after 15 years of followup.

Methods.

There were 210 women with SLE and 138 age-matched healthy women available for analysis after 15 years. Cardiovascular events (CVE) included angina pectoris, myocardial infarction (fatal and nonfatal), transient ischemic attack, and stroke (fatal and nonfatal). Analysis was performed with SAS 9.3 software; p < 0.05 was considered significant.

Results.

CVE occurred in 41/210 patients (19.5%) and 9/138 controls (6.5%), most of them in the second part (2008–2015) of the study (24/210, 11.4% vs 17/241, 7.1% in SLE group). Coronary artery disease was more common in patients (32/210, 15.2% vs 5/138, 3.6%, p = 0.0041). There was no significant difference for cerebrovascular disease (10/210, 4.8% vs 3/138, 2.2%, p = 0.213). SLE was the most prominent CVE predictor in the first 8 years (HR 2.8, 95% CI 1.3–6.3). Hypertension and diabetes were more frequent in patients who developed CVE during the second half of the study. Thirty-one deaths occurred in patients with SLE (10 because of CVD) and 6 in controls (none because of CVD).

Conclusion.

The relative importance of atherosclerotic risk factors is significantly differentiated over time in SLE. Disease-related factors seem to dominate CV risk during the early stages while traditional factors, partially related to corticosteroid treatment, play a significant role later in the disease course.

Systemic lupus erythematosus diagnosis and management

SLE presents many challenges for clinicians. The onset of disease may be insidious, with many different symptoms and signs, making early and accurate diagnosis challenging. Tests for SLE in the early stages lack specificity; those that are useful later often appear only after organ damage is manifest. Disease patterns are highly variable; flares are not predictable and not always associated with biomarkers. Children with SLE may have severe disease and present special management issues. Older SLE patients have complicating co-morbid conditions. Therapeutic interventions have improved over recent decades, but available drugs do not adequately control disease in many patients, and successful outcomes are limited by off-target effects; some of these become manifest with longer duration of treatment, now in part revealed by improved rates of survival. Despite all of these challenges, advances in understanding the biological basis of SLE have translated into more effective approaches to patient care. This review considers the current state of SLE diagnosis and management, with a focus on new approaches and anticipated advances.
