Cardiovascular disease in immune-mediated inflammatory diseases: A cross-sectional analysis of 6 cohorts

Exploring the therapeutic potential of layered double hydroxides and transition metal dichalcogenides through the convergence of rheumatology and nanotechnology using generative adversarial network

Two-dimensional Layered double hydroxides (LDHs) are highly used in the biomedical domain due to their biocompatibility, biodegradability, controlled drug loading and release capabilities, and improved cellular permeability. The interaction of LDHs with biological systems could facilitate targeted drug delivery and make them an attractive option for various biomedical applications. Rheumatoid Arthritis (RA) requires targeted drug delivery for optimum therapeutic outcomes. In this study, stacked double hydroxide nanocomposites with dextran sulphate modification (LDH-DS) were developed while exhibiting both targeting and pH-sensitivity for rheumatological conditions. This research examines the loading, release kinetics, and efficiency of the therapeutics of interest in the LDH-based drug delivery system. The mean size of LDH-DS particles (300.1 ± 8.12 nm) is -12.11 ± 0.4 mV. The encapsulation efficiency was 48.52%, and the loading efficacy was 16.81%. In vitro release tests indicate that the drug's discharge is modified more rapidly in PBS at pH 5.4 compared to pH 5.6, which later reached 7.3, showing the case sensitivity to pH. A generative adversarial network (GAN) is used to analyze the drug delivery system in rheumatology. The GAN model achieved high accuracy and classification rates of 99.3% and 99.0%, respectively, and a validity of 99.5%. The second and third administrations resulted in a significant change with p-values of 0.001 and 0.05, respectively. This investigation unequivocally demonstrated that LDH functions as a biocompatible drug delivery matrix, significantly improving delivery effectiveness.

Major Adverse Cardiovascular Events by Baseline Cardiovascular Risk in Patients with Ulcerative Colitis Treated with Tofacitinib: Data from the OCTAVE Clinical Programme

BACKGROUND AND AIMS

Patients with inflammatory bowel disease have increased risk of atherosclerotic cardiovascular [CV] disease [ASCVD]. Tofacitinib is an oral Janus kinase inhibitor for the treatment of ulcerative colitis [UC]. We report major adverse CV events [MACE] in the UC OCTAVE programme, stratified by baseline CV risk.

METHODS

Rates of MACE were analysed by baseline [first tofacitinib exposure] CV risk profile: prior ASCVD, or 10-year ASCVD risk categories [low, borderline, intermediate, high].

RESULTS

Of 1157 patients [2814.4 patient-years of exposure; ≤7.8 years' tofacitinib treatment], 4% had prior ASCVD and 83% had no prior ASCVD and low-borderline baseline 10-year ASCVD risk. Eight [0.7%] patients developed MACE; one had prior ASCVD. Incidence rates [unique patients with events/100 patient-years of exposure; 95% confidence intervals] for MACE were: 0.95 [0.02-5.27] in patients with prior ASCVD; and 1.81 [0.05-10.07], 1.54 [0.42-3.95], 0.00 [0.00-2.85], and 0.09 [0.01-0.32] in patients without prior ASCVD and with high, intermediate, -borderline, and low baseline 10-year ASCVD risk, respectively. For the 5/7 patients with MACE and without prior ASCVD, 10-year ASCVD risk scores were numerically higher [>1%] prior to MACE versus at baseline, primarily due to increasing age.

CONCLUSIONS

Most patients receiving tofacitinib in the UC OCTAVE programme had low baseline 10-year ASCVD risk. MACE were more frequent in patients with prior ASCVD and higher baseline CV risk. This analysis demonstrates potential associations between baseline CV risk and MACE in patients with UC, suggesting CV risk should be assessed individually in clinical practice.

Unlocking therapeutic potential: integration of drug repurposing and immunotherapy for various disease targeting

Drug repurposing, also known as drug repositioning, entails the application of pre-approved or formerly assessed drugs having potentially functional therapeutic amalgams for curing various disorders or disease conditions distinctive from their original remedial indication. It has surfaced as a substitute for the development of drugs for treating cancer, cardiovascular diseases, neurodegenerative disorders, and various infectious diseases like Covid-19. Although the earlier lines of findings in this area were serendipitous, recent advancements are based on patient centered approaches following systematic, translational, drug targeting practices that explore pathophysiological ailment mechanisms. The presence of definite information and numerous records with respect to beneficial properties, harmfulness, and pharmacologic characteristics of repurposed drugs increase the chances of approval in the clinical trial stages. The last few years have showcased the successful emergence of repurposed drug immunotherapy in treating various diseases. In this light, the present review emphasises on incorporation of drug repositioning with Immunotherapy targeted for several disorders.

Review article: Risk of cardiovascular events in patients with inflammatory bowel disease receiving small molecule drugs

BACKGROUND

In the context of an ageing inflammatory bowel disease (IBD) population, cardiovascular comorbidities become particularly relevant. Novel small molecule drugs (SMDs) for the treatment of moderate-to-severe IBD have been recently approved, including Janus kinase (JAK) inhibitors and sphingosine-1-phosphate receptor (S1P) modulators. Data from rheumatoid arthritis population have raised concerns about the risk of cardiovascular events with the use of tofacitinib, which was extrapolated to other immune-mediated diseases and other JAK inhibitors. S1P receptor modulation has been associated with potential cardiovascular events, especially bradycardia and cardiac conduction abnormalities.

AIM

To review the incidence of cardiovascular events with the use of SMDs in patients with IBD and to provide practical recommendations on mitigation strategies.

METHODS

Published literature was reviewed; recommendations were synthesised by experts in both cardiovascular diseases and IBD.

RESULTS

Evidence from the IBD population does not indicate a higher risk of cardiovascular events with tofacitinib and other JAK inhibitors. The risk is higher in patients with intermediate to high cardiovascular risk. S1P modulators may be associated with a dose-dependent, first-dose effect, transient risk of conduction abnormalities (bradycardia and AV block). Screening and monitoring of cardiovascular risk factors should be done in all patients with IBD. Risk stratification for cardiovascular disease should be performed before starting treatment with SMDs.

CONCLUSIONS

Available evidence of both JAK inhibitors and S1P modulators indicates a reassuring safety profile of SMDs from the cardiovascular perspective in the overall IBD population. Efforts should be made to identify patients with IBD at a higher risk of cardiovascular events.

Cardiovascular events and risk in patients with systemic lupus erythematosus: Systematic literature review and meta-analysis

BACKGROUND

Systemic lupus erythematosus (SLE) is an autoimmune disease that typically affects women aged 16-55 years. Cardiovascular disease (CVD) is a well-recognized complication of SLE. This systematic literature review and meta-analysis evaluated the relative risk (RR; compared with non-SLE controls), absolute risk (AR; as incidence proportion, n/N), and incidence rate (IR) of CVD events (including stroke, myocardial infarction [MI], and CVD [composite or undefined]) in adult patients with SLE. The RR of CV risk factors (including hypertension, diabetes, and metabolic syndrome [MetS]) was also examined.

METHODS

PubMed and Embase were searched on September 10, 2020. Observational studies published between January 2010 and September 2020 that reported RR, AR, and/or IR of CVD events, or RR of CV risk factors, were eligible. Pooled risk estimates were calculated using a random-effects model.

RESULTS

Forty-six studies (16 cross-sectional, 15 retrospective cohort, 14 prospective cohort, and 1 case-control) were included in meta-analyses. Most studies were considered high quality (Critical Appraisal Skills Programme checklists). Compared with adults without SLE, patients with SLE had statistically significantly higher RRs (95% CIs) of stroke (2.51 [2.03-3.10]; 12 studies), MI (2.92 [2.45-3.48]; 11 studies), CVD (2.24 [1.94-2.59]; 8 studies), and hypertension (2.70 [1.48-4.92]; 7 studies). RRs of diabetes (1.24 [0.78-1.96]; 3 studies) and MetS (1.49 [0.95-2.33]; 7 studies) were elevated but not significant. RRs of stroke and MI were generally higher in younger versus older patients with SLE. In patients with SLE, the pooled estimate of AR (95% CI) was 0.03 (0.02-0.05), 0.01 (0.00-0.02), and 0.06 (0.03-0.10) for stroke (7 studies), MI (6 studies), and CVD (8 studies), respectively. The pooled estimate of IR per 1000 person-years (95% CI) was 4.72 (3.35-6.32), 2.81 (1.61-4.32), and 11.21 (8.48-14.32) for stroke (10 studies), MI (6 studies), and CVD (8 studies), respectively. Although heterogeneity (based on I² value) was high in most analyses, sensitivity analyses confirmed the robustness of the pooled estimates.

CONCLUSIONS

This meta-analysis found an increased risk of stroke, MI, CVD, and hypertension in patients with SLE compared with the general population, despite substantial heterogeneity across the included studies.

Inflammatory profile of incident cases of late-onset compared with young-onset rheumatoid arthritis: A nested cohort study

OBJECTIVES

To describe the characteristics of patients between late-onset rheumatoid arthritis (LORA) with young-onset (YORA), and analyze their association with cumulative inflammatory burden.

METHODS

We performed a nested cohort study in a prospective cohort comprising 110 patients with rheumatoid arthritis (RA) and 110 age- and sex-matched controls. The main variable was cumulative inflammatory activity according to the 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR). High activity was defined as DAS28 ≥ 3.2 and low activity as DAS28 < 3.2. The other variables recorded were inflammatory cytokines, physical function, and comorbid conditions. Two multivariate models were run to identify factors associated with cumulative inflammatory activity.

RESULTS

A total of 22/110 patients (20%) met the criteria for LORA (≥ 60 years). Patients with LORA more frequently had comorbid conditions than patients with YORA and controls. Compared with YORA patients, more LORA patients had cumulative high inflammatory activity from onset [13 (59%) vs. 28 (31%); p = 0.018] and high values for CRP (p = 0.039) and IL-6 (p = 0.045). Cumulative high inflammatory activity in patients with RA was associated with LORA [OR (95% CI) 4.69 (1.49-10.71); p = 0.008], smoking [OR (95% CI) 2.07 (1.13-3.78); p = 0.017], anti-citrullinated peptide antibody [OR (95% CI) 3.24 (1.15-9.13); p = 0.025], average Health Assessment Questionnaire (HAQ) score [OR (95% CI) 2.09 (1.03-14.23); p = 0.034], and physical activity [OR (95% CI) 0.99 (0.99-0.99); p = 0.010]. The second model revealed similar associations with inflammatory activity in patients with LORA.

CONCLUSION

Control of inflammation after diagnosis is poorer and comorbidity more frequent in patients with LORA than in YORA patients and healthy controls.

Prevention and risk assessment of cardiovascular events in a population of patients with psoriasis and psoriatic arthritis

Psoriasis is a chronic, inflammatory, often relapsing disease that is frequently associated with other diseases of similar pathogenesis. The multi-morbidity in the psoriasis population significantly impedes both diagnosis and implementation of appropriate preventive measures. However, the common denominator for this group of diseases is the inflammatory process that initiates the appearance of subsequent symptoms and health consequences, most of which can be avoided or alleviated by modifying the patient’s lifestyle and incorporating appropriate treatment. Health consequences associated with systemic inflammation include cardiovascular incidents and other cardiometabolic diseases.

This article was based on available publications on the onset, incidence, and prevention of cardiovascular disease in the psoriasis patient population.

Trends in the occurrence of ischaemic heart disease over time in rheumatoid arthritis: 1821 patients from 1972 to 2017

OBJECTIVE

To evaluate trends of acute myocardial infarction (AMI) and ischaemic heart disease (IHD) in rheumatoid arthritis (RA) patients compared with the general population over time.

METHOD

We performed a retrospective cohort study of 1821 RA patients diagnosed from 1972 to 2013. Aggregated counts of the total population of the same county (Hordaland, Norway) and period were used for comparison. Information on AMI and IHD events was obtained from hospital patient administrative systems or cardiovascular registries. We estimated incidence rates and excess of events [standardized event ratio (SER) with 95% confidence interval (CI)] compared with the general population by Poisson regression.

RESULTS

There was an average annual decline of 1.6% in age- and gender-adjusted AMI incidence rates from 1972 to 2017 (p < 0.035). The difference in events (excess events) in RA patients compared with the general population declined on average by 1.3% per year for AMI and by 2.3% for IHD from 1972 to 2014. There were no significant excess AMI (SER 1.05, 95% CI 0.82-1.35) or IHD events (SER 1.02, 95% CI 0.89-1.16) for RA patients diagnosed after 1998 compared with the general population.

CONCLUSION

Incidence rates and excess events of AMI and IHD in RA patients declined from 1972 to 2017. There were no excess AMI or IHD events in RA patients diagnosed after 1998 compared with the general population.

Update on Cardiovascular Risk and Obesity in Psoriatic Arthritis

PsA is characterized by a high prevalence of cardiovascular (CV) comorbidities. Recognizing these comorbidities is critical due to their influence on the quality of life and the choice of therapy. Imaging techniques also play an important role in the evaluation of the CV risk in psoriatic disease, improving the prediction of CV events when combined with clinical scores as a predictive tool. Meta-analyses point to a significant reduction in the incidence of CV events associated with the suppression of inflammatory activity when using systemic therapies. Consequently, the mortality rate in PsA patients has fallen in the last 40 years and is now similar to that of the general population, including cardiovascular causes. Obesity is an especially relevant CV comorbidity in patients with psoriatic disease, most of whom are overweight/obese. Body mass index (BMI) is a risk factor for PsA and a causal relationship with psoriasis has been demonstrated by Mendelian randomized studies. The study of fat distribution shows that patients with psoriasis are characterized by visceral fat accumulation, which correlates with CV risk measurements. These findings suggest that approaches to the prevention and treatment of psoriatic disease might come from targeting adiposity levels, in addition to the immune pathways. Weight loss treatment with low energy diets in patients with PsA has been associated with significant improvements in disease activity. Novel strategies using a multimorbidity approach, focused more on patients outcomes, are necessary to better address comorbidities, improve clinical outcomes and the quality of life of patients with psoriatic disease.

Acute Coronary Syndromes and Inflammatory Bowel Disease: The Gut-Heart Connection

(1) Background: Inflammatory bowel disease (IBD) induces a process of systemic inflammation, sharing common ground with acute coronary syndromes (ACS). Growing evidence points towards a possible association between IBD and an increased risk of ACS, yet the topic is still inconclusive. Therefore, we conducted a systematic review aiming to clarify these gaps in the evidence. (2) Methods: We conducted a systematic search on EMBASE, Cochrane Library, and PubMed, identifying observational studies published prior to November 2020. The diagnosis of IBD was confirmed via histopathology or codes. Full articles that fulfilled our criteria were included. Quality assessment was performed using the Newcastle-Ottawa scale (NOS). (3) Results: We included twenty observational studies with a total population of ~132 million subjects. Fifteen studies reported a significant association between ACS and IBD, while the remaining five studies reported no increase in ACS risk in IBD patients. (4) Conclusions: ACS risk in IBD patients is related to hospitalizations, acute active flares, periods of active disease, and complications, with a risk reduction during remission. Interestingly, a general increase in ACS risk was reported in younger IBD patients. The role of corticosteroids and oral contraceptive pills in increasing the ACS risk of IBD patients should be investigated.

Antirheumatic therapy is not associated with changes in circulating N-terminal pro-brain natriuretic peptide levels in patients with autoimmune arthritis

Background

Patients with autoimmune arthritis (AA) are at increased risk for impaired cardiac function and heart failure. This may be partly due to the effect of inflammation in heart function. The impact of antirheumatic drugs on cardiac dysfunction in AA remains controversial. Therefore, we aimed to examine effects of antirheumatic treatment on serum N-terminal pro-brain natriuretic peptide (NT-proBNP) in AA patients and its relationship to inflammatory markers.

Methods

We examined 115 patients with AA (64 rheumatoid arthritis (RA), 31 psoriatic arthritis and 20 ankylosis spondylitis) starting with methotrexate (MTX) monotherapy or tumor necrosis factor inhibitors (TNFi) with or without MTX co-medication. NT-proBNP (measured in serum by ECLIA from Roche Diagnostics), and other clinical and laboratory parameters were evaluated at baseline, after 6 weeks and 6 months of treatment.

Results

NT-proBNP levels did not change significantly after 6 weeks and 6 months of antirheumatic therapy (p_{baseline-6weeks} = 0.939; p_{baseline-6months} = 0.485), although there was a modest improvement from 6 weeks to 6 months in the MTX only treatment group (median difference = -18.2 [95% CI = -32.3 to -4.06], p = 0.013). There was no difference in the effects of MTX monotherapy and TNFi regimen on NT-proBNP levels. The changes in NT-proBNP after antirheumatic treatment positively correlated with changes in C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR). Baseline NT-proBNP levels were related to baseline CRP and ESR levels, and some other established markers of disease activities in crude analyses.

Conclusion

Circulating levels of NT-proBNP were related to established inflammatory markers at baseline, and the changes in NT-proBNP after antirheumatic treatment were positively related to these markers. Nevertheless, antirheumatic therapy did not seem to affect NT-proBNP levels compared to baseline, even though inflammatory markers significantly improved.

Association of systemic lupus erythematosus with peripheral arterial disease: a meta-analysis of literature studies

OBJECTIVE

SLE patients have an increased cardiovascular morbidity and mortality. Contrasting data are available about the association between peripheral arterial disease (PAD) and SLE. We aimed to perform a meta-analysis of studies evaluating the association between SLE and PAD.

METHODS

Studies were systematically searched in the PubMed, Web of Science, Scopus and EMBASE databases according to preferred reporting items for systematic reviews and meta-analyses guidelines.

RESULTS

Eight studies reporting on 263 258 SLE patients and 768 487 controls showed that the prevalence of PAD was 15.8% (95% CI: 10.5%, 23.2%) in SLE patients and 3.9% (95% CI: 1.8%, 7.9%) in controls with a corresponding odds ratio of 4.1 (95% CI: 1.5, 11.6; P <0.001). In addition, five studies reporting on ankle-brachial index showed significantly lower values in 280 SLE patients as compared with 201 controls (mean difference: -0.018; 95% CI: -0.034, -0.001; P =0.033). Meta-regression models showed that age, hypertension and diabetes were inversely associated with the difference in the prevalence of PAD between SLE patients and non-SLE controls, whereas no effect for all the other clinical and demographic variables on the evaluated outcome was found.

CONCLUSION

SLE patients exhibit an increased prevalence of PAD and lower ankle-brachial index values as compared with non-SLE controls. This should be considered when planning prevention, interventional and rehabilitation strategies for these chronic patients with functional disability and poor long-term outcomes.

Cardiovascular Disease in Spondyloarthritides

The spondyloarthritides are a group of chronic systemic inflammatory joint diseases, the main types being ankylosing spondylitis (AS) and psoriatic arthritis (PsA). Evidence accumulating during the last decades suggests that patients with AS or PsA carry an increased risk for cardiovascular disease and cardiovascular death. This risk appears to be mediated by systemic inflammation over and above classical cardiovascular risk factors. The excess cardiovascular risk in those patients has been formally acknowledged by scientific organizations, which have called physicians' attention to the matter. The application by Rheumatologists of new effective anti-rheumatic treatments and treat-to-target strategies seems to benefit patients from a cardiovascular point of view, as well. However, more data are needed in order to verify whether anti-rheumatic treatments do have an effect on cardiovascular risk and whether there are differences among them in this regard. Most importantly, a higher level of awareness of the cardiovascular risk is needed among patients and healthcare providers, better tools to recognize at-risk patients and, ultimately, commitment to address in parallel both the musculoskeletal and the cardiovascular aspect of the disease.

Dextran sulfate-modified pH-sensitive layered double hydroxide nanocomposites for treatment of rheumatoid arthritis

To reduce the side effects of methotrexate and increase its anti-inflammatory effect, we developed a drug delivery system, dextran sulfate-modified methotrexate-loaded layered double hydroxide nanocomposites (LDH-MTX-DS), with both targeting and pH-sensitivity for the treatment of rheumatoid arthritis. The nanocomposites had a mean particle size of 303.1 ± 8.07 nm, zeta potential of - 12.4 ± 0.7 mV, encapsulation efficiency of 49.64%, and loading efficiency of 16.81%. In vitro release experiments demonstrated that the drug was released faster in PBS at pH 5.5 than at pH 7.4, which reflected the pH-sensitivity of this system. Cellular uptake assays displayed higher cellular uptake rate of the dextran sulfate-modified targeting carrier compared with that of a non-targeting carrier (P < 0.01), which indicated that the LDH-MTX-DS could actively target scavenger receptors on the surface of activated RAW 264.7 cells. In vivo pharmacodynamic experiments showed that, after the second (P < 0.001) and third (P < 0.05) administrations, the preparation group exhibited significantly improved therapeutic efficacy in adjuvant-induced arthritis (AIA) rats when compared with free MTX alone. These results indicated that this drug delivery system was promising in the treatment of rheumatoid arthritis. Graphical abstract.

Targeting perivascular and epicardial adipose tissue inflammation: therapeutic opportunities for cardiovascular disease

Major shifts in human lifestyle and dietary habits toward sedentary behavior and refined food intake triggered steep increase in the incidence of metabolic disorders including obesity and Type 2 diabetes. Patients with metabolic disease are at a high risk of cardiovascular complications ranging from microvascular dysfunction to cardiometabolic syndromes including heart failure. Despite significant advances in the standards of care for obese and diabetic patients, current therapeutic approaches are not always successful in averting the accompanying cardiovascular deterioration. There is a strong relationship between adipose inflammation seen in metabolic disorders and detrimental changes in cardiovascular structure and function. The particular importance of epicardial and perivascular adipose pools emerged as main modulators of the physiology or pathology of heart and blood vessels. Here, we review the peculiarities of these two fat depots in terms of their origin, function, and pathological changes during metabolic deterioration. We highlight the rationale for pharmacological targeting of the perivascular and epicardial adipose tissue or associated signaling pathways as potential disease modifying approaches in cardiometabolic syndromes.

Association of Ustekinumab vs TNF Inhibitor Therapy With Risk of Atrial Fibrillation and Cardiovascular Events in Patients With Psoriasis or Psoriatic Arthritis

Importance

Accumulating evidence indicates that there is an increased risk of cardiovascular disease among patients with psoriatic disease. Although an emerging concern that the risk of atrial fibrillation (AF) may also be higher in this patient population adds to the growing support of initiating early interventions to control systemic inflammation, evidence on the comparative cardiovascular safety of current biologic treatments remains limited.

Objective

To evaluate the risk of AF and major adverse cardiovascular events (MACE) associated with use of ustekinumab vs tumor necrosis factor inhibitors (TNFi) in patients with psoriasis or psoriatic arthritis.

Design, Setting, and Participants

This cohort study included data from a nationwide sample of 78 162 commercially insured patients in 2 US commercial insurance databases (Optum and MarketScan) from September 25, 2009, through September 30, 2015. Patients were included if they were 18 years or older, had psoriasis or psoriatic arthritis, and initiated ustekinumab or a TNFi therapy. Exclusion criteria included history of AF or receipt of antiarrhythmic or anticoagulant therapy during the baseline period.

Exposures

Initiation of ustekinumab vs TNFi therapy.

Main Outcomes and Measures

Incident AF and MACE, including myocardial infarction, stroke, or coronary revascularization.

Results

A total of 60 028 patients with psoriasis or psoriatic arthritis (9071 ustekinumab initiators and 50 957 TNFi initiators) were included in the analyses. The mean (SD) age was 46 (13) years in Optum and 47 (13) in MarketScan, and 29 495 (49.1%) were male. Overall crude incidence rates (reported per 1000 person-years) for AF were 5.0 (95% CI, 3.8-6.5) for ustekinumab initiators and 4.7 (95% CI, 4.2-5.2) for TNFi initiators, and for MACE were 6.2 (95% CI, 4.9-7.8) for ustekinumab initiators and 6.1 (95% CI, 5.5-6.7) for TNFi initiators. The combined adjusted hazard ratio for incident AF among ustekinumab initiators was 1.08 (95% CI, 0.76-1.54) and for MACE among ustekinumab initiators was 1.10 (95% CI, 0.80-1.52) compared with TNFi initiators.

Conclusions and Relevance

No substantially different risk of incident AF or MACE after initiation of ustekinumab vs TNFi was observed in this study. This information may be helpful when weighing the risks and benefits of various systemic treatment strategies for psoriatic disease.

Subsequent Cardiovascular Events Among Patients With Rheumatoid Arthritis, Psoriatic Arthritis, or Psoriasis: Patterns of Disease-Modifying Antirheumatic Drug Treatment

Objective

To examine disease‐modifying antirheumatic drug (DMARD) treatments and estimate the risk of a subsequent cardiovascular (CV) event following an initial CV event in patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or psoriasis.

Methods

We analyzed data from MarketScan claims databases (January 1, 2006 to June 30, 2015) for adults with RA, PsA, or psoriasis and an initial/index CV event (acute myocardial infarction, stroke, or coronary revascularization) while receiving DMARDs (tumor necrosis factor inhibitor [TNFi] biologic DMARDs [bDMARDs], conventional synthetic DMARDs [csDMARDs], or non‐TNFi bDMARDs). We studied DMARD treatment patterns following the index event and rates of subsequent CV events. We used Cox regression to investigate predictors of DMARD discontinuation and risk factors for subsequent CV events.

Results

Among 10,254 patients, 15.3% discontinued and 15.5% switched DMARD therapy after the index CV event. Independent predictors of DMARD discontinuation included a psoriasis diagnosis, renal disease, hypertension, heart failure, diabetes mellitus, older age, and baseline csDMARD or non‐TNFi bDMARD use (versus TNFi bDMARDs). Rates per 1,000 patient‐years of subsequent events were 75.2 (95% confidence interval [95% CI] 54.4–96.0) for patients taking TNFi bDMARDs, 83.6 (95% CI 53.3–113.9) for csDMARDs, and 122.4 (95% CI 60.6–184.3) for non‐TNFi bDMARDs. A diagnosis of RA (versus psoriasis) and heart failure at baseline, but not a DMARD pattern after the index event, were independently associated with an increased risk of subsequent CV event.

Conclusion

In this large nationwide study, nearly one‐third of patients with RA, PsA, or psoriasis switched or discontinued DMARD therapy following a CV event. There was no association between DMARD class and the risk of a subsequent CV event.

Diagnostic performance of aPS/PT antibodies in neuropsychiatric lupus and cardiovascular complications of systemic lupus erythematosus

Background: Systemic lupus erythematosus (SLE) is associated with a constellation of complications affecting multiple organs, including neuropsychiatric manifestations (NPSLE) and ischaemic events, leading to increased long-term morbidity. Antiphospholipid antibodies (aPL) are a major determinant of vascular inflammation and thromboembolic risk. The diagnostic role of anti-phosphatidylserine/prothrombin (aPS/PT) antibodies in this setting is incompletely defined.Aim: To verify whether aPS/PT add to diagnostics and disease stratification in patients with SLE with or without other aPL.Methods: 131 consecutive patients were studied, including 20 patients with SLE and secondary antiphospholipid syndrome (APS). aPS/PT IgG and IgM were assessed through ELISA and patients were stratified based on the presence of other aPL, on their clinical and laboratory features at time of blood sampling and on their clinical history. Synthetic indices of disease activity, chronic damage and cardiovascular risk were calculated at time of venipuncture.Results: Fifty-one (38.9%) patients with SLE had aPS/PT and 15 (11.5%) patients had aPS/PT as the only aPL (aPS/PT-only). aPS/PT-only patients had a significantly higher prevalence of NPSLE than quadruple aPL-negative patients (p = .007). Patients with aPS/PT were more likely to have a history of ischaemia, thrombocytopenia and Libman-Sacks' endocarditis. The presence of aPS/PT also associated with previous accrual of at least one damage item (p = .043), but had limited predictive values for damage progression in the short term.Conclusion: aPS/PT antibodies provide non-redundant information that could contribute to risk assessment and stratification of patients with SLE.

Should all patients with psoriasis receive statins? Analysis according to different strategies

Background

Different strategies have been proposed for the cardiovascular risk management of patients with psoriasis.

Objective

To estimate the cardiovascular risk and evaluate two cardiovascular prevention strategies in patients with psoriasis, analyzing which proportion of patients would be candidates to receive statin therapy.

Methods

A retrospective cohort was selected from a secondary database. All patients >18 years with psoriasis without cardiovascular disease or lipid-lowering treatment were included. The atherosclerotic cardiovascular disease calculator (2018 American College of Cardiology/American Heart Association guidelines) and the Systematic Coronary Risk Evaluation risk calculator (2016 European Society of Cardiology/European Society of Atherosclerosis guidelines) were calculated. The SCORE risk value was adjusted by a multiplication factor of 1.5. The recommendations for the indication of statins suggested by both guidelines were analyzed.

Results

A total of 892 patients (mean age 59.9 ± 16.5 years, 54.5% women) were included. The median atherosclerotic cardiovascular disease calculator and Systematic Coronary Risk Evaluation values were 13.4% (IQR 6.1–27.0%) and 1.9% (IQR 0.4–5.2), respectively. According to the atherosclerotic cardiovascular disease calculator, 20.1%, 11.0%, 32.9%, and 36.4% of the population was classified at low, borderline, moderate, or high risk. Applying the Systematic Coronary Risk Evaluation, 26.5%, 42.9%, 20.8%, and 9.8% of patients were stratified as having low, moderate, high, or very high risk, respectively. The proportion of subjects with statin indication was similar using both strategies: 60.1% and 60.9% for the 2018 American College of Cardiology/American Heart Association and 2016 European Society of Cardiology/European Society of Atherosclerosis guidelines, respectively.

Study limitations

This was a secondary database study. Data on the severity of psoriasis and pharmacological treatments were not included in the analysis.

Conclusion

This population with psoriasis was mostly classified at moderate–high risk and the statin therapy indication was similar when applying the two strategies evaluated.

Misunderstandings Between Platelets and Neutrophils Build in Chronic Inflammation

Regulated hemostasis, inflammation and innate immunity entail extensive interactions between platelets and neutrophils. Under physiological conditions, vascular inflammation offers a template for the establishment of effective intravascular immunity, with platelets providing neutrophils with an array of signals that increase their activation threshold, thus limiting collateral damage to tissues and promoting termination of the inflammatory response. By contrast, persistent systemic inflammation as observed in immune-mediated diseases, such as systemic vasculitides, systemic sclerosis, systemic lupus erythematosus or rheumatoid arthritis is characterized by platelet and neutrophil reciprocal activation, which ultimately culminates in the generation of thrombo-inflammatory lesions, fostering vascular injury and organ damage. Here, we discuss recent evidence regarding the multifaceted aspects of platelet-neutrophil interactions from bone marrow precursors to shed microparticles. Moreover, we analyse shared and disease-specific events due to an aberrant deployment of these interactions in human diseases. To restore communications between the pillars of the immune-hemostatic continuum constitutes a fascinating challenge for the near future.

Incidence and Prevalence of Major Adverse Cardiovascular Events in Rheumatoid Arthritis, Psoriatic Arthritis, and Axial Spondyloarthritis

OBJECTIVE

To compare the risk of major adverse cardiovascular events (MACE) in a large observational cohort of patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), or axial spondyloarthritis (SpA) patients.

METHODS

We conducted a mixed retrospective and prospective cohort study using data from patients with RA, PsA, or axial SpA included in the Swiss Clinical Quality Management registry. The primary outcome of interest was a composite of myocardial infarction, transient or permanent cerebrovascular event, or cardiovascular-associated death.

RESULTS

A total of 5,315 patients were eligible for the analysis of incidence, with a total follow-up time of 37,495 patient-years for RA, 19,837 patient-years for axial SpA, and 9,171 patient-years for PsA. The unadjusted incidence rate of MACE per 1,000 patient-years was 2.67 for RA, 1.41 for axial SpA, and 1.42 for PsA. Compared to the unadjusted incidence rate ratios (IRRs) in patients with RA, those in patients with axial SpA were 0.53 (95% confidence interval [95% CI] 0.34-0.80; P = 0.003) and in patients with PsA were 0.53 (95% CI 0.30-0.95; P = 0.03). After adjustment for traditional cardiovascular risk factors, age at disease onset, sex, and disease duration, the difference was not significant between RA and axial SpA (adjusted IRR 0.93 [95% CI 0.51-1.69]; P = 0.80) or between RA and PsA (adjusted IRR 0.56 [95% CI 0.27-1.14]; P = 0.11). We found a similar result with the analysis of prevalence.

CONCLUSION

There was no significant difference in the incidence and prevalence of MACE between RA and axial SpA or PsA, suggesting that inflammation, rather than a particular disease, drives the increased risk of cardiovascular disease.

Factors Associated with Relapse and Dependence on Glucocorticoids in Giant Cell Arteritis

OBJECTIVE

To identify characteristics and factors associated with relapse and glucocorticoid (GC) dependence in patients with giant cell arteritis (GCA).

METHODS

We retrospectively analyzed 326 consecutive patients with GCA followed for at least 12 months. Factors associated with relapse and GC dependence were identified in multivariable analyses.

RESULTS

The 326 patients (73% women) were followed up for 62 (12-262) months. During followup, 171 (52%) patients relapsed, including 113 (35%) who developed GC dependence. Relapsing patients had less history of stroke (p = 0.01) and presented large-vessel vasculitis (LVV) more frequently on imaging (p = 0.01) than patients without relapse. During the first months, therapeutic strategy did not differ among relapsing and nonrelapsing patients. GC-dependent patients were less likely to have a history of stroke (p = 0.004) and presented LVV on imaging more frequently (p = 0.005) than patients without GC-dependent disease. In multivariable analyses, LVV was an independent predictive factor of relapse (HR 1.49, 95% CI 1.002-2.12; p = 0.04) and GC dependence (OR 2.19, 95% CI 1.19-4.05; p = 0.01). Conversely, stroke was a protective factor against relapse (HR 0.21, 95% CI 0.03-0.68; p = 0.005) and GC-dependent disease (OR 0.10, 95% CI 0.001-0.31; p = 0.0005). Patients with a GC-dependent disease who received a GC-sparing agent had a shorter GC treatment duration than those without (p = 0.008).

CONCLUSION

In this study, LVV was an independent predictor of relapse and GC dependence. Further prospective studies are needed to confirm these findings and to determine whether patients with LVV require a different treatment approach.

Increased Risk of Hypertension Associated with Spondyloarthritis Disease Duration: Results from the ASAS-COMOSPA Study

OBJECTIVE

Spondyloarthritis (SpA) is associated with a number of cardiovascular (CV) comorbidities. We examined the association of SpA disease duration and delay in diagnosis with CV-related conditions.

METHODS

Using data from the COMOSPA study, the associations between SpA disease duration and CV-related conditions were evaluated in univariable and multivariable logistic regression models. Each model examined 1 CV-related factor as dependent and "SpA disease duration" as a predictor, adjusted for relevant confounders.

RESULTS

Data from 3923 subjects (median SpA disease duration 5.1 yrs, interquartile range 1.3-11.8 yrs) were available for analysis. The main CV-related conditions were hypertension (HTN; 22.4%), ischemic heart disease (2.6%), stroke (1.3%), and diabetes mellitus (5.5%). HTN was associated with SpA disease duration in both univariable and multivariable analysis, with an OR of 1.129 (95% CI 1.072-1.189; p < 0.001) for each 5-year increase in SpA disease duration. Other factors associated with HTN were age, male sex, current body mass index, ever steroid therapy, and ever synthetic disease-modifying antirheumatic drug therapy, but not nonsteroidal antiinflammatory drugs (NSAID). In subgroup analysis, the strongest association of HTN and disease duration was seen in subjects with the axial-only SpA phenotype (OR 1.202, 95% CI 1.053-1.372) but not in those with peripheral-only SpA (OR 0.902, 95% CI 0.760-1.070). The other CV conditions were not associated with SpA disease duration.

CONCLUSION

Duration of SpA disease in the ASAS-COMOSPA cohort is associated with higher odds of HTN, particularly in those with axial disease, but not with other CV-related conditions. The association with HTN does not appear to be related to NSAID exposure.

Epicardial Adipose Tissue May Mediate Deleterious Effects of Obesity and Inflammation on the Myocardium

Epicardial adipose tissue has unique properties that distinguish it from other depots of visceral fat. Rather than having distinct boundaries, the epicardium shares an unobstructed microcirculation with the underlying myocardium, and in healthy conditions, produces cytokines that nourish the heart. However, in chronic inflammatory disorders (especially those leading to heart failure with preserved ejection fraction), the epicardium becomes a site of deranged adipogenesis, leading to the secretion of proinflammatory adipokines that can cause atrial and ventricular fibrosis. Accordingly, in patients at risk of heart failure with preserved ejection fraction, drugs that promote the accumulation or inflammation of epicardial adipocytes may lead to heart failure, whereas treatments that ameliorate the proinflammatory characteristics of epicardial fat may reduce the risk of heart failure. These observations suggest that epicardial adipose tissue is a transducer of the adverse effects of systemic inflammation and metabolic disorders on the heart, and thus, represents an important target for therapeutic interventions.

Methotrexate therapy impacts on red cell distribution width and its predictive value for cardiovascular events in patients with rheumatoid arthritis

BACKGROUND

Methotrexate (MTX) is well known to affect folic acid metabolism, so MTX treatment can result in alterations of mean corpuscular volume (MCV), which may impact on red cell distribution width (RDW), as MCV levels feed into RDW calculation. We thus questioned whether RDW levels and subsequently its diagnostic utility in RA subjects, as reported before, are influenced by ongoing MTX therapy.We assessed the impact of disease modifying drug (DMARD) treatment, especially MTX, on RDW and evaluated their influence on the predictive value of RDW for cardiovascular (CV) events in patients with rheumatoid arthritis (RA). As far as we know, this is the first study evaluating the influence of MTX on RDW.

METHODS

Medical treatment, disease activity, laboratory parameters and history of CV events were retrospectively analysed in 385 RA patients at disease onset and at last follow up at our clinic. Additionally, in patients with CV event, data were recorded at last follow up prior the CV event.

RESULTS

Disease parameters and laboratory findings associated with a serious vascular event were older age (p < 0,001), longer disease duration (p = 0,002) and a higher RDW at diagnosis (p = 0,025). No differences in RDW levels became evident with any other treatment regimen beside MTX. MTX treated patients had significantly higher RDW compared to subjects without this drug (p < 0,001). In RA patients without MTX treatment, we found RDW level significantly different between those with versus without a CV event, whereas this difference disappeared in subjects receiving MTX.

CONCLUSION

MTX impacts on RDW and might therefor reduce its prognostic value for CV events in patients taking MTX, whereas an increased RDW at diagnosis remains an early risk predictor for myocardial infarction and stroke in RA patients.

Subclinical atherosclerosis and history of cardiovascular events in Italian patients with rheumatoid arthritis: Results from a cross-sectional, multicenter GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) study

Several studies have pointed out a significant association between rheumatoid arthritis (RA) and accelerated atherosclerosis. At the best of our knowledge, no such study has been carried out in a large Italian series and, in this study, we aimed to investigate the prevalence of both subclinical atherosclerosis and history of cardiovascular events (CVEs), in patients consecutively admitted from January 1, 2015 to December 31, 2015 to Rheumatology Units throughout the whole Italy.Centers members of GIRRCS (Gruppo Italiano di Ricerca in Reumatologia Clinica e Sperimentale) were invited to enrol patients consecutively admitted from January 1, 2015 to December 31, 2015 and satisfying American College of Rheumatology/ European League Against Rheumatism criteria for RA and to investigate each of them for: traditional cardiovascular risk factors: sex, age, smoking habit, total cholesterol, triglycerides, glycaemia, high blood pressure, metabolic syndrome (MS), type 2 diabetes (T2D); RA features: disease duration as assessed from the first symptom, disease activity as evaluated by DAS28, radiographic damage as assessed by hands and feet x-ray, and previous joint surgery; prevalence of both subclinical atherosclerosis and history of CVEs.Eight centers participated to the study. From January 1, 2015 to December 31, 2015, the 1176 patients, who had been investigated for all the items, were enrolled in the study. They were mostly women (80.52%), with a median age of 60 years (range, 18-91 years), a median disease duration of 12 years (range, 0.8-25 years), seropositive in 69.21%. Nineteen percent were in remission; 17.51% presented low disease activity; 39.45% moderate disease activity; 22.61% high disease activity.Eighty-two patients (6.9%) had a history for CVEs (58 myocardial infarction, 38 heart failure, 10 ischemic transitory attack, and 7 stroke). This figure appears to be lower than that reported worldwide (8.5%). After excluding the 82 patients with a history of CV events, subclinical atherosclerosis was detected in 16% of our patients, (176 patients), a figure lower than that reported worldwide (32.7%) and in previous Italian studies.This is the first Italian multicenter study on subclinical and clinical atherosclerosis in patients with RA. We pointed out a low prevalence of both subclinical atherosclerosis and history of CV events.
