Cardiovascular risk profile at the onset of psoriatic arthritis: a population-based cohort study

The management of cardiovascular risk in psoriatic disease: A bridge over troubled water

Evidence that psoriatic disease is burdened by an excess cardiovascular (CV) risk has accrued, however many questions remain unanswered. Although an interplay between traditional risk factors inflammation, disease activity and pharmacological therapies, as observed in rheumatoid arthritis (RA), may account for this increased risk, metabolic comorbidities rather than inflammation seem to have a leading role in psoriatic disease. Therefore, specific approaches, risk factors targeting and the importance of traditional risk factors and inflammation management need to be considered. The purpose of this review article is to discuss current data on CV risk in psoriatic disease, and to outline similarities and differences with RA in the light of international recommendations. Arguments in favour of developing specific guidance for CV prevention in psoriatic disease are discussed.

[Immune-mediated inflammatory diseases in Germany : A cross-sectional analysis of comorbidities and pharmacotherapy]

BACKGROUND

Immune-mediated inflammatory diseases (IMID) can lead to a substantial disease burden for those affected, in particular by the concomitant occurrence of other IMIDs or in the presence of comorbidities. The care of patients with IMIDs is complex and involves various medical disciplines.

OBJECTIVE

To describe the burden of disease and the current routine drug treatment of patients with IMID.

MATERIAL AND METHODS

The retrospective cross-sectional analysis was based on statutory health insurance claims data from the InGef database. Prevalent patients with psoriasis (Pso), psoriatic arthritis (PsA), spondylarthritis (SpA), rheumatoid arthritis (RA), Crohn's disease (MC), ulcerative colitis (CU), or connective tissue disease were identified among 3,988,695 insured patients in 2018. The concomitant occurrence of different IMIDs and the extent to which patients with IMID are affected by other comorbidities compared to a reference population were investigated. The current routine drug treatment was described based on the use of predefined forms of treatment.

RESULTS

In the database 188,440 patients with IMID (4.7%) were identified. Compared to the reference population the prevalence of comorbidities, such as depressive episodes and cardiovascular risk factors was higher in patients with IMID. For MC, CU, RA, and PsA disease-modifying antirheumatic drugs (DMARD) and classical systemic forms of treatment were used most commonly. In Pso, SpA, and connective tissue disease nonsteroidal anti-inflammatory drugs (NSAID) were the most frequently used treatment often in combination with other drugs.

CONCLUSION

A considerable number of patients with IMIDs (16.9-27.5%) suffer from different diseases of the IMID group. They are frequently affected by accompanying illnesses and require interdisciplinary medical treatment.

Body mass index is associated with health-related quality of life and disease characteristics in young adults with juvenile idiopathic arthritis

BACKGROUND

There is a growing interest concerning the relationship between obesity and several medical conditions and inflammation. Nevertheless, there is a lack of studies regarding body mass index (BMI) among patients with juvenile idiopathic arthritis (JIA). Our aim was to investigate the impact of BMI on health-related quality of life (HRQoL) measured with a 36-Item Short Form Survey (SF-36), disease activity, and disability in young adults with JIA.

METHODS

This study is a part of the population-based Nordic JIA cohort study. All newly diagnosed patients with JIA were recruited consecutively between 1997-2000 in specific regions in the Nordic countries. Patients in this sub-study were enrolled from 434 patients who attended their 18-year follow-up visit. Patients were classified according to the World Health Organization (WHO) into four groups based on their BMI. HRQoL, disease characteristics, disability, fatigue, sleep quality, physical activity, pain, comorbidities, and social status were assessed.

RESULTS

Three hundred fifty-five patients from the original study cohort were enrolled in this study and 72% of them were female. Mean age was 23.9 (± SD 4.4) years. A significant relationship was found between the JIA categories and BMI groups (p = 0.014). A significant relationship was also found between BMI and disease activity scores (DAS28) (p = 0.028), disability (p < 0.001), pain (p = 0.013), fatigue (p = 0.035), and sleep quality (p = 0.044). Moreover, a significant relationship between BMI and HRQoL regarding bodily pain (p = 0.010) and general health (p = 0.048) was revealed when adjusted for sex, age, and JIA subtype.

CONCLUSION

We discovered that BMI was significantly related to HRQoL, disease activity, and disability. BMI deserves more attention considering the treatment options and outcome of JIA in young adults.

Derivation and Internal Validation of a Disease-Specific Cardiovascular Risk Prediction Model for Patients With Psoriatic Arthritis and Psoriasis

OBJECTIVE

To address suboptimal cardiovascular risk prediction in patients with psoriatic disease (PsD), we developed and internally validated a five-year disease-specific cardiovascular risk prediction model.

METHODS

We analyzed data from a prospective cohort of participants with PsD without a history of cardiovascular events. Traditional cardiovascular risk factors and PsD-related measures of disease activity were considered as potential predictors. The study outcome included nonfatal and fatal cardiovascular events. A base prediction model included 10 traditional cardiovascular risk factors. Eight PsD-related factors were assessed by adding them to the base model to create expanded models, which were controlled for PsD therapies. Variable selection was performed using Least Absolute Shrinkage and Selection Operator (LASSO) penalized regression with 10-fold cross-validation. Model performance was assessed using measures of discrimination and calibration and measures of sensitivity and specificity.

RESULTS

Between 1992 and 2020, 85 of 1,336 participants developed cardiovascular events. Discrimination of the base model (with traditional cardiovascular risk factors alone) was excellent, with an area under the receiver operator characteristic curve (AUC) of 85.5 (95% confidence interval [CI] 81.9-89.1). Optimal models did not select any of the tested disease-specific factors. In a sensitivity analysis, which excluded lipid lowering and antihypertensive treatments, the number of damaged joints was selected in the expanded model. However, this model did not improve risk discrimination compared to the base model (AUC 85.5, 95% CI 82.0-89.1).

CONCLUSION

Traditional cardiovascular risk factors alone are effective in predicting cardiovascular risk in patients with PsD. A risk score based on these factors performed well, indicating excellent discrimination and calibration.

Prevalence of Cardiovascular Risk Factors in Saudi Patients With Psoriatic Arthritis: A Single-Center Retrospective Cohort Study

Background Psoriatic arthritis (PsA) is an extremely heterogeneous disease with numerous articular phenotypes and extra-articular manifestations. It is common for patients with PsA to have coexisting medical conditions. In recent studies, PsA patients were found to have a greater prevalence of cardiovascular risk factors when compared to non-PsA groups. Objectives This study aimed to describe the prevalence of cardiovascular risk factors among Saudi psoriatic arthritis patients treated at King Abdulaziz Medical City (KAMC), Riyadh. Methods A hundred and twenty-six patients with psoriatic arthritis diagnoses were enrolled in this study. Patients who were 18-years-old or older, had PsA diagnosed by a rheumatologist, and met the Classification Criteria for Psoriatic Arthritis (CASPAR) criteria were included in the study population. Patients were excluded from the study if they were younger than 18, did not fulfill the CASPAR criteria, did not have a documented diagnosis by a rheumatologist, or had been diagnosed with any type of joint arthritis in the past. In this retrospective cohort article, we investigated the frequency of risk factors for cardiovascular disease such as [hypertension (HTN), dyslipidemia (DLP), diabetes mellitus (DM), obesity, and coronary heart disease (CHD)] and non-established risk factors such as [HbA1C, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)]. SPSS version 12.0 for Windows (SPSS Inc.) was used for statistical analysis. The threshold for statistical significance was set at 5%. Results A hundred and twenty-six PsA patients were enrolled in this study, 30 (24%) had PsA for less than two years (early), and 96 (76%) had PsA for more than two years (established). When the analysis was performed, the mean age was 47.5 years, and the mean age at diagnosis of PsA was 42.4 years. Of them, 89 (71%) were female while 37 (29%) were male. Established PsA patients were significantly older at the time of analysis than early PsA patients (49.2 vs. 41.8 years; P= 0.007). Furthermore, established PsA patients had a longer duration of PsA than those with early PsA (6.3 vs. 1.5 years; P= <0.001). The most frequently reported comorbidity was obesity (61%) followed by DLP (43%), HTN (34%), DM (30%), and CHD (11%). CV comorbidities did not differ between subgroups. However, patients with established PsA had a higher prevalence of DLP, especially females. Additionally, patients with early PsA had greater rates of HTN than those with established PsA, and patients with early PsA were more likely to have CHD. Conclusion This study confirms that PsA is linked with cardiovascular (CV) morbidity. When evaluating PsA, future studies should take these CV conditions into consideration.

Serum Interleukin-34 in Psoriatic arthritis patients and its correlation with disease 1 activity, and subclinical atherosclerosis

Background

Psoriatic arthritis (PsA) is a chronic multi-domains autoimmune inflammatory disorder. Patients with PsA have a significant prevalence of cardiovascular affection. Upregulated Interleukin-34 (IL-34) has been seen in many autoimmune disorders, and also in atherosclerotic plaques. The aim of this observational case–control study was to evaluate the serum levels of il-34 in PsA patients and correlate between its level and disease activity, and subclinical cardiovascular affection.

Results

In this study, there were 70 PsA patients and 70 healthy volunteers, 43 patients were on Methotrexate, 6 on sulfasalazine, while 40 patients were on biological therapy either monotherapy or in combination with DMARDs. There were significant differences between PsA patients and controls in ESR, high sensitivity-CRP, total lipid profile, and IL-34 levels (p < 0.05) while there were no significant differences regarding Echo and ECG results. Also, we found that there was significant elevation in DAPSA score, hs-CRP, IL-34, and cIMT in the active patients when we compared them with inactive patients. IL-34 had significant positive correlations with DAPSA score, hs-CRP, and cIMT (r = 0.654, 0.579, and 0.658 respectively).

Conclusion

Serum interleukin-34 is an important marker in PsA as its levels were elevated in PsA patients and were correlated with disease activity and subclinical cardiovascular affection.

High inflammatory burden predicts cardiovascular events in patients with axial spondyloarthritis: a long-term follow-up study

Background

Axial spondyloarthritis (axSpA) patients are at higher risk of cardiovascular (CV) disease (CVD) than the general population, partly due to consequences of inflammation or its treatment. But relationship between inflammation in axSpA and cardiovascular events (CVE) is unknown.

Objectives

To examine whether inflammatory burden over time can predict CVE independent of baseline CV risk factors in axSpA patients.

Design

A cohort analysis was performed in patients who had been recruited since January 2001. The primary outcome was a first CVE occurring between January 2001 and December 2020.

Methods

Three CVD risk scores were computed at baseline. The performance of the original and modified (*1.5 multiplication factor) CV risk algorithms were assessed. Time-varying Cox proportional hazard models and Kaplan-Meier survival analysis were used to assess whether inflammatory burden (Bath ankylosing spondylitis disease activity index [BASDAI] and inflammatory markers), nonsteroidal anti-inflammatory drugs (NSAIDs) and disease modifying antirheumatic drugs (DMARDs) can predict the development of first CVE.

Results

463 patients (35 [26-45] years, male: 360 [77.8%]) were recruited. After a median follow-up of 12 (7-19) years, 61 patients (13.2%) experienced a first CVE. Traditional/modified CV risk scores underestimated CV risk. Erythrocyte sedimentation rate (ESR) ⩾ 20 mm/h was associated with a significantly higher risk of CVE during follow-up (HR: 2.07, 95%CI [1.10, 3.98], p = 0.008). Active disease as indicated by a rising BASDAI also showed positive trend towards a higher risk of developing CVE over time. After adjusting for CV risk scores in the multivariable models, high ESR level (ESR ⩾ 20 mm/h) over time remained significantly associated with a higher risk of developing CV events.

Conclusion

Increased inflammatory burden as reflected by elevated ESR levels (ESR ⩾ 20) was associated with increased risk of CVE, while the use of NSAIDs and DMARDs were not.

Cognitive impairment in patients with psoriatic arthritis

BACKGROUND

Psoriatic arthritis (PsA) is an inflammatory rheumatic disorder associated with cutaneous psoriasis. Neurological manifestations are not uncommon in rheumatic diseases and recent studies point to a possible underestimation of cognitive impairment in this group of diseases. Our aim was to assess the cognitive impairment in patients with PsA.

METHODS

We carried out a cross-sectional case-control study with consecutive patients with PsA. Trained interviewers conducted structured and standardized in-person assessments. At baseline, functional limitations were characterized using the Health Assessment Questionnaire (HAQ). Cognitive function was evaluated with the Montreal Cognitive Assessment (MoCA) and neuropsychiatric symptoms were investigated with the Hospital Anxiety and Depression Scale (HADS). Using a proper statistical analysis, we compared the differences in the neurological outcomes between cases and controls.

RESULTS

A total of 37 patients with PsA and 36 healthy controls were included in our study. Patients with PsA had a worse MoCA score when compared to controls (p = 0.01). The proportion of patients with cognitive impairment according to MoCA between cases and controls was also statistically significant (91.9% vs 58.3%, p = 0.002). Executive skills, naming, language, and abstraction were the most affected domains. There was no statistical difference between the prevalence of neuropsychiatric symptoms between the two groups. Patients with increased functional limitations are associated with poor cognitive performance (p < 0.05).

CONCLUSION

Cognitive impairment might be a neurological manifestation of PsA.

Cardiovascular Diseases in the Patients with Psoriatic Arthritis

There are limited data regarding the burden and trend of cardiovascular diseases (CVD) in psoriatic arthritis (PsA). We analyzed the National Inpatient Sample database from January 2005 to December 2018 to examine the hospitalization trends amongst adults with PsA primarily for heart failure (HF), acute myocardial infarction (AMI), and stroke. The primary outcomes of interest included in-hospital mortality, length of stay (LOS), and inflation-adjusted cost. The age-adjusted percentage of HF hospitalizations among PsA patients decreased from 2.5% (2005/06) to 1.4% (2011/12; P-trend 0.013) and subsequently increased to 2.0% (2017/18; P-trend 0.044). The age-adjusted percentage of AMI hospitalizations among PsA patients showed a non-statistically significant decreasing trend from 2.1% (2005/06) to 1.7% (2011/12; P-trend 0.248) and showed a non-statistically significant increase to 2.3% (2017/18; P-trend 0.056). The age-adjusted stroke hospitalizations increased from 1.1% (2005/06) to 1.3% (2017/18; P-trend 0.036). Apart from a decrease in adjusted inflation-adjusted cost among heart failure hospitalizations, there was no significant change in inpatient mortality, length of stay or hospital cost, during the study period. We found an increasing trend of cardiovascular hospitalizations in patients with PsA. These findings will raise awareness and inform further research and clinical practice for PSA patients with CVD.

High Prevalence of Metabolic Syndrome in Patients With Psoriatic Arthritis From Northeastern Brazil: Association With Traditional Cardiovascular Risk Factors and Biologic Disease-Modifying Antirheumatic Drugs

OBJECTIVE

The aims of this cross-sectional study were to evaluate the prevalence of MetS in PsA patients compared with sex- and age-matched healthy controls and to test possible associations with clinical and laboratory variables.

METHODS

The prevalence of MetS was determined for 76 PsA patients and 76 sex- and age-matched healthy controls, using the criteria of NCEP/ATPIII and Harmonizing, adjusted for South Americans. Multivariate logistic regression analysis was used to identify independent risk factors for MetS.

RESULTS

Metabolic syndrome was significantly more prevalent in the PsA group than in the control group (53.9% vs 18.4%, p < 0.001). Psoriatic arthritis was associated with hypertension, diabetes mellitus, increased waist circumference (WC), elevated body mass index, and raised levels of blood glucose and triglycerides. When comparing MetS and non-Mets PsA patients, MetS was not significantly associated with disease activity, skin involvement, or quality of life. In the logistic regression model, the variables independently associated with MetS were use of biologic disease-modifying antirheumatic drugs (p = 0.001), elevated arterial pressure (p = 0.006), age (p = 0.0015), WC (p = 0.004), and low HDL (p = 0.042).

CONCLUSIONS

In this study on PsA patients from Northeastern Brazil, MetS was highly prevalent and associated with biologic disease-modifying antirheumatic drugs use, increased WC, and low HDL.

Comparison of carotid artery ultrasound and Framingham risk score for discriminating coronary artery disease in patients with psoriatic arthritis

Objectives

This study aimed to assess the performance of carotid ultrasound (US) parameters alone or in combination with Framingham Risk Score (FRS) in discriminating patients with psoriatic arthritis (PsA) with and without coronary artery disease (CAD).

Methods

Ninety-one patients with PsA (56 males; age: 50±11 years, disease duration: 9.4±9.2 years) without overt cardiovascular (CV) diseases were recruited. Carotid intima-media thickness (cIMT), the presence of plaque and total plaque area (TPA) was determined by high-resolution US. CAD was defined as the presence of any coronary plaque on coronary CT angiography (CCTA). Obstructive-CAD (O-CAD) was defined as >50% stenosis of the lumen.

Results

Thirty-five (38%) patients had carotid plaque. Fifty-four (59%) patients had CAD (CAD+) and 9 (10%) patients had O-CAD (O-CAD+). No significant associations between the presence of carotid plaque and CAD were found. However, cIMT and TPA were higher in both the CAD+ and O-CAD+ group compared with the CAD− or O-CAD− groups, respectively. Multivariate logistic regression analysis revealed that mean cIMT was an independent explanatory variable associated with CAD and O-CAD, while maximum cIMT and TPA were independent explanatory variables associated with O-CAD after adjusting for covariates. The optimal cut-offs for detecting the presence of CAD were FRS >5% and mean cIMT at 0.62 mm (AUC: 0.71; sensitivity: 67%; specificity: 76%), while the optimal cut-offs for detecting the presence of O-CAD were FRS >10% in combination with mean cIMT at 0.73 mm (AUC: 0.71; sensitivity: 56%; specificity: 85%).

Conclusion

US parameters including cIMT and TPA may be considered in addition to FRS for CV risk stratification in patients with PsA.

Psoriatic Arthritis and Metabolic Syndrome: Is There a Role for Disease Modifying Anti-Rheumatic Drugs?

Although psoriatic arthritis (PsA) primarily leads to joint and skin damage, it is associated with higher prevalence of metabolic syndrome (MetS) and its components, namely hypertension, dyslipidemia, obesity, and type II diabetes. Additionally, chronic inflammation is known to aggravate these cardiometabolic factors, thus explaining the enhanced cardiovascular (CV) morbidity and mortality in RA. Furthermore, emerging evidence suggest that some risk factors can fuel inflammation, thus pointing to a bidirectional crosstalk between inflammation and cardiometabolic factors. Therefore, dampening inflammation by disease-modifying anti-rheumatic drugs (DMARDs) may be thought to ameliorate MetS burden and thus, CV risk and disease severity. In fact, recommendations for PsA management emphasize the need of considering comorbidities to guide the treatment decision process. However, the existing evidence on the impact of approved DMARDs in PsA on MetS and MetS components is far from being optimal, thus representing a major challenge for the clinical setting. Although a beneficial effect of some DMARDs such as methotrexate, TNF inhibitors and some small molecules is clear, no head-to-head studies are published and no evidence is available for other therapeutic approaches such as IL-23 or IL-17 inhibitors. This narrative review summarizes the main evidence related to the effect of DMARDs on MetS outcomes in PsA patients and identify the main limitations, research needs and future perspectives in this scenario.

Psoriatic disease is associated with systemic inflammation, endothelial activation, and altered haemostatic function

Psoriasis is a chronic, immune-mediated inflammatory skin disease, affecting approximately 2% of the general population, which can be accompanied by psoriatic arthritis (PsA). The condition has been associated with an increased cardiovascular burden. Hypercoagulability is a potential underlying mechanism that may contribute to the increased risk of major cardiovascular events in psoriatic individuals. Whole blood samples were collected from 20 PsA patients and 20 healthy individuals. The concentrations of inflammatory molecules (C-reactive protein, serum amyloid A, soluble intercellular adhesion molecule-1, soluble vascular cell adhesion molecule-1, and soluble P-selectin) were determined by enzyme-linked immunosorbent assays. In addition, clotting efficiency was evaluated by thromboelastography. The fibrin network architecture was also assessed by scanning electron microscopy. Elevated levels of circulating inflammatory molecules were significantly associated with the presence of psoriatic disease. Furthermore, an increased tendency towards thrombus formation was significantly predictive of disease presence. Scanning electron microscopy revealed that fibrin clots were denser in psoriatic individuals, compared to healthy controls, with an increased fibrin fibre diameter associated with psoriatic disease. Our results add to the accumulating evidence of the systemic nature of psoriasis and the subsequent risk of cardiovascular comorbidities, potentially due to an acquired hypercoagulability. We suggest that haemostatic function should be monitored carefully in psoriatic patients that present with severe disease, due to the pre-eminent risk of developing thrombotic complications.

Systematic review and meta-analysis on prevalence of metabolic syndrome in psoriatic arthritis, rheumatoid arthritis and psoriasis

BACKGROUND

Psoriatic arthritis (PsA), rheumatoid arthritis (RA) and psoriasis (PsO) are associated with systemic inflammation and increased cardiovascular mortality and morbidity. Metabolic syndrome (MetS) is associated with systemic inflammation, and conditions associated with MetS, such as obesity, are associated with difficulty in attaining minimal disease activity (MDA) in individuals with inflammatory arthritis. This systematic review aims to determine whether there is an increased prevalence of MetS in PsA populations compared with PsO and RA populations.

METHODS

A systematic review was conducted to assess the prevalence of MetS in PsA, PsO, and RA populations following Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The quality of the studies reviewed was assessed using the Joanna Briggs Institute Checklist for Prevalence Studies.

RESULTS

The pooled prevalence of MetS in PsA populations was 0.46 ± 0.06 (95% CI 0.40-0.51). In comparison, the prevalence of MetS in PsO and RA populations was 0.34 ± 0.03 (95% CI 0.32-0.37) and 0.31 ± 0.04 (95% CI 0.27-0.35), respectively. Patients with PsA were 1.62 ± 0.036 (95% CI 1.50-1.74) and 1.66 ± 0.038 (95% CI 1.54-1.79) times more likely to have MetS compared with PsO and RA populations.

CONCLUSION

The prevalence of MetS is significantly increased in PsA populations compared with PsO and RA populations. Further studies should be performed using a standardized definition of MetS in PsA, RA, and PsO populations to determine whether addressing the metabolic components in MetS offers any therapeutic benefits and in terms of attaining MDA and improving cardiovascular health.

Psoriatic arthritis and the association with cardiometabolic disease: a narrative review

Psoriatic arthritis (PsA) is associated with a higher burden of cardiometabolic disorders, such as hypertension, dyslipidemia, diabetes, obesity, and cardiovascular disease (CVD), compared with the general population. These comorbidities are associated with the severity of disease, and adversely affect treatment outcomes in PsA. Comorbidities lead to increased physician visits and medications for patients and make the selection and maintenance of therapies challenging for physicians. Moreover, CVD is a leading cause of mortality in PsA. Therefore, optimal management of PsA should include not only treating the skin and joint disease, but also identifying comorbidities early, and managing them to improve long-term outcomes. Further studies are needed to understand the complex mechanisms, interactions, and trajectories of cardiometabolic comorbidities in psoriatic disease.

Cardiovascular Risk Scores in Axial Spondyloarthritis Versus the General Population: A Cross-sectional Study

OBJECTIVE

Cardiovascular (CV) morbidity and mortality are increased in axial spondyloarthritis (axSpA).We conducted a cross-sectional study evaluating the 10-year atherosclerotic cardiovascular disease (ASCVD) risk in axSpA compared to the general US population.

METHODS

We included 211 adults, 40-75 years old with ankylosing spondylitis (AS) or nonradiographic axSpA from 2 sites, who had available data on comorbidities, medication use, blood pressure measures, and laboratory cholesterol values. General population comparators from the 2009-2014 National Health and Examination Survey (NHANES) cycles were matched 4:1 to subjects, on age, sex, and race. We estimated the prevalence ratio for a 10-year ASCVD risk score ≥ 7.5% comparing axSpA and matched NHANES comparators using conditional Poisson regression.

RESULTS

Overall, subjects were 53.9 ± 11.2 years old, 69% were male, and 74% were White. The mean 10-year ASCVD risk score was 6.7 ± 6.9% for those with axSpA, and 9.0 ± 10.5% for NHANES comparators. Compared to those with axSpA, the prevalence of current smoking and diabetes was higher among NHANES comparators. The estimated prevalence ratio for a 10-year ASCVD risk score ≥ 7.5% comparing those with axSpA and their age-, sex-, and race-matched comparators was 0.96 (95% CI 0.74-1.24).

CONCLUSION

The prevalence of a 10-year ASCVD risk score ≥ 7.5% was not significantly different comparing axSpA patients and those drawn from the general population who were similar in terms of age, sex, and race. Future studies should focus on improved CV risk prediction in axSpA, because underestimation by a general population risk score may potentially explain these results.

The Potential Benefit of Monitoring Oxidative Stress and Inflammation in the Prevention of Non-Communicable Diseases (NCDs)

The significant increase in worldwide morbidity and mortality from non-communicable diseases (NCDs) indicates that the efficacy of existing strategies addressing this crisis may need improvement. Early identification of the metabolic irregularities associated with the disease process may be a key to developing early intervention strategies. Unhealthy lifestyle behaviours are well established drivers of the development of several NCDs, but the impact of such behaviours on health can vary considerably between individuals. How can it be determined if an individual's unique set of lifestyle behaviours is producing disease? Accumulating evidence suggests that lifestyle-associated activation of oxidative and inflammatory processes is primary driver of the cell and tissue damage which underpins the development of NCDs. However, the benefit of monitoring subclinical inflammation and oxidative activity has not yet been established. After reviewing relevant studies in this context, we suggest that quantification of oxidative stress and inflammatory biomarkers during the disease-free prodromal stage of NCD development may have clinical relevance as a timely indicator of the presence of subclinical metabolic changes, in the individual, portending the development of disease. Monitoring markers of oxidative and inflammatory activity may therefore enable earlier and more efficient strategies to both prevent NCD development and/or monitor the effectiveness of treatment.

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.

Erectile Dysfunction in Men With Psoriatic Arthritis: A Population-based Cohort Study

OBJECTIVE

To define the incidence of erectile dysfunction (ED) in a population-based cohort of men with psoriatic arthritis (PsA).

METHODS

Data pertaining to demographics, ED, and potential confounding diagnosis were extracted from a comprehensive medical record system for a population-based cohort of men with PsA and an age-matched male comparator cohort. Cumulative incidence of ED adjusted for competing risk of death was compared between the 2 cohorts.

RESULTS

There were 128 age-matched pairs of men with PsA and without PsA in the described cohorts. At baseline, there was a 7% prevalence of ED in men with PsA prior to diagnosis compared to a 3% prevalence of ED in the comparator cohort (P = 0.16). After PsA diagnosis/index date, diagnosis with PsA was associated with an increased risk of ED (age-adjusted HR 1.45, 95% CI 0.79-2.68), but this association did not reach statistical significance. This was based on 24 cases of ED in the men with PsA and 18 cases within the comparator cohort. No confounding factors or ED treatment strategies differed significantly between men with PsA and ED and comparators with ED.

CONCLUSION

Men with PsA may have an increased risk of ED, which was detected but likely underpowered in this study. Whether this difference is secondary to higher prevalence of traditional risk factors of ED in men with PsA compared to the general population will require further study.

Obesity and Psoriatic Arthritis: A Narrative Review

Patients with psoriatic arthritis (PsA) have a higher burden of cardio-metabolic comorbidities like obesity, hypertension, diabetes, and cardiovascular disease compared to the general population. Adipose tissue is thought to promote a chronic low grade inflammatory state through inflammatory mediators like tumor necrosis factor alpha (TNFα), interleukin-6 (IL-6), leptin, and adiponectin. A higher body mass index (BMI) is a risk factor for development of PsA and affects disease activity and response to therapy including both disease-modifying anti-rheumatic drugs (DMARDs) and tumor necrosis factor inhibitors (TNFi). Obesity has an impact on the morbidity in PsA, particularly cardiovascular and/or metabolic. Patients with PsA have a higher cardiovascular risk and obesity may have an additive impact on morbidity and mortality. This review explores the relationship between obesity and PsA.

DAPSA, carotid plaque and cardiovascular events in psoriatic arthritis: a longitudinal study

OBJECTIVE

To examine whether Disease Activity in Psoriatic Arthritis (DAPSA) reflecting the inflammatory component of psoriatic arthritis (PsA) can predict cardiovascular (CV) events independent of traditional CV risk factors and subclinical carotid atherosclerosis.

METHODS

A cohort analysis was performed in patients with PsA who had been followed since 2006. The outcome of interest was first CV event. Four different CV disease (CVD) risk scores and DAPSA were computed at baseline. The presence of carotid plaque (CP) and carotid intima-media thickness (CIMT) was also determined in a subgroup of patients using high-resolution ultrasound. The association between DAPSA, CVD risk scores, CP, CIMT and the occurrence of CV events was assessed using Cox proportional hazard models.

RESULTS

189 patients with PsA (mean age: 48.9 years; male: 104 (55.0%)) were recruited. After a median follow-up of 9.9 years, 27 (14.3%) patients developed a CV event. Higher DAPSA was significantly associated with an increased risk of developing CV events (HR: 1.04, 95% CI (1.01 to 1.08), p=0.009). The association remained significant after adjusting for all CV risk scores in the multivariable models. In the subgroup analysis, 154 patients underwent carotid ultrasound assessment and 23 (14.9%) of them experienced a CV event. CP was associated with increased risk of developing CV events after adjusting for three CV risk scores and DAPSA, with HR ranging from 2.35 to 3.42.

CONCLUSION

Higher DAPSA and the presence of CP could independently predict CVD events in addition to traditional CV risk scores in patients with PsA.

Role of Carotid Ultrasound and Systematic Coronary Risk Evaluation Charts for the Cardiovascular Risk Stratification of Patients with Psoriatic Arthritis

OBJECTIVE

The assessment of the cardiovascular (CV) risk is recommended in patients with chronic inflammatory rheumatic diseases. The objectives of this study were to assess the CV risk profile in a cohort of patients with psoriatic arthritis (PsA), to determine the presence of subclinical cardiovascular disease by carotid ultrasound (US), and to study the association of CV disease to PsA characteristics.

METHODS

This was a cross-sectional multicentric descriptive study. The clinical CV risk was calculated with Systematic Coronary Risk Evaluation (SCORE) charts. Common carotid US was conducted to evaluate the carotid wall intima-media thickness and the presence of atheroma plaques. Patients were reclassified upon US results. Multivariate analyses were performed to identify associations of US carotid abnormalities with the classical CV risk factors and PsA characteristics.

RESULTS

The study included 176 patients with PsA. The SCORE-estimated CV risk was intermediate in 65.3% of the patients. In the US study, 32% of the patients had abnormalities, and 30.8% of the patients were upgraded and reclassified as very high risk owing to the presence of atheroma. Subclinical CV disease was associated with age and dyslipidemia but not with other risk factors. It was associated with axial disease in the subgroup with intermediate risk, and with C-reactive protein levels in patients with high risk.

CONCLUSION

Many patients with PsA have clinical estimated intermediate or high risk of a fatal CV event. A carotid US study detects subclinical vascular disease and may be useful to depict the real risk. The presence of atheroma is only partially explained by the classic CV risk factors.

Sex and Cardiovascular Involvement in Inflammatory Joint Diseases

The term inflammatory joint disease (IJD) encompasses a group of chronic conditions with predominant joint involvement. They share an increased risk of cardiovascular (CV) complications. However, the implication of the sex in the risk of CV disease in IJD has not been specifically addressed. The aim of this work is to assess the influence of sex on the clinical expression of CV manifestations associated to IJD. With this objective, an update of the current knowledge of the sex influence on CV disease in patients with IJD was conducted. A PubMed database search of the most relevant literature on this topic was performed mainly based on studies published in English over the last 10 years. Although most studies on IJD were not specifically designed to address sex differences regarding CV complications, it seems that men with rheumatoid arthritis (RA) are at higher risk of pericarditis, ischemic heart disease, heart failure (HF) with reduced ejection fraction (EF), and CV mortality than women with RA. In contrast, HF with preserved EF and diastolic dysfunction is more frequent in women with RA. Men with ankylosing spondylitis present more frequently disorders of the conduction system and aortic valvulopathy than women. A limited number of studies addressed CV differences according to sex in psoriatic arthritis. Although there are some differences according to sex in the clinical expression of CV complications in patients with IJD, much research is still needed to better identify the implication of sex in the risk of CV disease in these patients.

Value of Carotid Ultrasound in Cardiovascular Risk Stratification in Patients With Psoriatic Disease

OBJECTIVE

This study aimed to assess whether subclinical atherosclerosis, as evaluated by carotid ultrasound, could predict incident cardiovascular events (CVEs) in patients with psoriatic disease (PsD) and determine whether incorporation of imaging data could improve CV risk prediction by the Framingham Risk Score (FRS).

METHODS

In this cohort analysis, patients with PsD underwent ultrasound assessment of the carotid arteries at baseline. The extent of atherosclerosis was assessed using carotid intima-media thickness (CIMT) and total plaque area (TPA). Incident CVEs (new or recurrent) that occurred following the ultrasound assessment were identified. The association between measures of carotid atherosclerosis and the risk of developing an incident CVE was evaluated using Cox proportional hazards models, with adjustment for the FRS.

RESULTS

In total, 559 patients with PsD were assessed, of whom 23 had incident CVEs ascertained. The calculated rate of developing a first CVE during the study period was 1.11 events per 100 patient-years (95% confidence interval [95% CI] 0.74-1.67). When analyzed separately in Cox proportional hazards models that were controlled for the FRS, the TPA (hazard ratio [HR] 3.74, 95% CI 1.55-8.85; P = 0.003), mean CIMT (HR 1.21, 95% CI 1.03-1.42; P = 0.02), maximal CIMT (HR 1.11, 95% CI 1.01-1.22; P = 0.03), and high TPA category (HR 3.25, 95% CI 1.18-8.95; P = 0.02) were each predictive of incident CVEs in patients with PsD.

CONCLUSION

The burden of carotid atherosclerosis is associated with an increased risk of developing future CVEs. Combining vascular imaging data with information on traditional CV risk factors could improve the accuracy of CV risk stratification in patients with PsD.

Cardiac and cardiovascular morbidities in patients with psoriatic arthritis: a population-based case control study

OBJECTIVE

To assess the prevalence of risk factors associated with cardiovascular disease (CVD) and CVD-related morbidity in a large Middle-Eastern psoriatic arthritis (PsA) cohort.

METHOD

A retrospective case control study was conducted using Israel's largest health care provider's patient database from 2000 to 2013. For each patient with PsA, 10 patients with no history of psoriasis or arthritis were matched for age and sex. Analysis of CVD-related risk factors and morbidity included hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus type 2 (DM-2), obesity, smoking, ischemic heart disease (IHD), congestive heart failure (CHF), cerebrovascular accident (CVA), carotid artery disease, peripheral vascular disease (PVD), aortic aneurism, valvular heart disease (VHD), and cardiomyopathy. Statistical analysis was conducted using t test and chi-square tests as appropriate. Univariate and multivariable logistic regression models assessed the association between PsA and CVD-related risk factors and morbidity.

RESULTS

Three thousand one hundred sixty-one PsA patients were included, with average age 58 ± 15.0 years, of whom 53.4% were women. Increased prevalence of DM-2, HLD, HTN, and obesity (OR 1.7, 1.5, 1.5, 1.5 respectively) was noted in the PsA group. Increased prevalence of IHD (p < 0.0001), PVD (p < 0.0001), CHF (p = 0.002), VHD (p < 0.0001), and cardiomyopathy (p = 0.006) was found in the PsA group compared to the control group even after adjusting for CVD risk factors.

CONCLUSIONS

A high prevalence of CVD-related risk factors and morbidity was found in this Middle Eastern PsA population, in accordance with data from other geographic regions. These results emphasize the importance of clinician awareness of the increased risk for CVD-related complications in PsA patients.

Cardiovascular morbidity and mortality in ankylosing spondylitis and psoriatic arthritis

The cardiovascular burden in inflammatory rheumatic diseases is well recognized. Recently, this burden has been highlighted in ankylosing spondylitis (also known as radiographic axial spondyloarthritis) and psoriatic arthritis. We review the cardiovascular morbidity and mortality in these diseases, as well as the prevalence and incidence of traditional cardiovascular risk factors. We examine the contribution of anti-inflammatory therapy with nonsteroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and TNF inhibitors on the cardiovascular risk profile. Finally, we examine the available recommendations for the management of cardiovascular comorbidity, as they apply to the spondyloarthritis population.

Endothelial Dysfunction in Children with Juvenile Psoriatic Arthritis

BACKGROUND

To evaluate the presence of endothelial dysfunction in Slovak children with juvenile psoriatic arthritis in the absence of classic cardiovascular risk factors in order to assess its relationship to the disease activity and disability.

METHODS

25 juvenile psoriatic arthritis patients (JPSA) and 25 healthy controls aged 6-19 years were enrolled into this study. In all subjects vascular measurements over a period of three years (January 2013 - January 2016) were performed, in accordance with the guidelines for ultrasonographic evaluation of FMD% (flow-mediated endothelial dependent vasodilatation) of the brachial artery. The measured items were compared to the variables reflecting the disease activity and disability.

RESULTS

Significantly lower FMD% values in patients with JPSA when compared to healthy controls {mean(SD), median, range: 5.49% (3.77), 3.55, 0.3-13.0 vs. 9.28% (1.72), 9.3, 6.4-13.1} (p < 0.001) have been documented. Strong correlations between FMD% values and disease duration (p < 0.01), non-specific inflammatory markers levels (p < 0.001) or functional disability (p < 0.01) have been observed. Significantly lower FMD% values in patients with an early disease onset (JPSA onset < 5 years of age) when compared to the rest of JPSA group {mean (SD), median, range: 4.39% (2.47), 4.45, 0.9-13.2 vs. 6.38% (1.42), 6.3, 3.2-12.1} (p < 0.01) have also been detected.

CONCLUSION

Study is the only one addressing endothelial dysfunction development in Slovak children with psoriatic arthritides. We state that endothelial dysfunction is present in these patients even during childhood and in the absence of classic cardiovascular risk factors. Its development seems to be related to an early disease onset as well as to the increased disease activity and disability. Potential genetic predictors have also been identified.

Incidental Abdominal Aortic Aneurysm in the Psoriasis Patient: A Case Report and Review of Literature

Background

Psoriasis is defined as a chronic inflammatory disease involving keratinocytes hyperproliferation of the epidermis with the acceleration in the epidermal turnover time, which is affected by various factors including genetic, immunologic, and environmental factors. There is a high risk for the development of premature cardiovascular diseases among patients with psoriasis as well as one of the life-threatening events is an aortic aneurysm (AA).

Case report

We report a 60-year-old man with the diagnosed psoriatic disease that an enlargement of the abdominal AA was incidentally found by annual check-up.

Conclusion

Further large-scale studies are needed to find the prevalence of abdominal AA in psoriasis and the appropriate screening time of that in this disease.

Performances of five risk algorithms in predicting cardiovascular events in patients with Psoriatic Arthritis: An Italian bicentric study

Introduction

In patients with psoriatic arthritis (PsA) an increased cardiovascular (CV) risk has been observed. Recently, a EULAR taskforce suggested to use a multiplication by the factor of 1.5 of CV risk algorithms in patients with inflammatory arthritis. This study aims to evaluate the performance of five original and adapted according to EULAR recommendations CV risk algorithms in PsA: SCORE, CUORE, Framingham Risk Score (FRS), QRISK2, and Reynold’s Risk Score (RRS).

Methods

Prospectively collected data from two Italian cohorts were used. Discriminatory ability for CV risk prediction was evaluated by the area under the ROC curves. Calibration between predicted and observed events was assessed by Hosmer-Lemeshow (HL) tests. Sensibility and specificity were calculated for low-to-intermediate and intermediate-to-high risk cut-offs.

Results

One hundred fifty-five patients were enrolled with an observation of 1550 patient/years. Area under the ROC were 0.7679 (95% CI 0.64768 to 0.88812), 0.864 (95% CI 0.79675 to 0.93278), 0.7575 (95% CI 0.65784 to 0.85708), 0.8660 (95% CI 0.79428 to 0.93772), and 0.7183 (95% CI 0.57795 to 0.85862) for SCORE, CUORE, FRS, QRSIK2, and RRS, respectively. HL tests demonstrated poor model fit (p<0.05) for SCORE, CUORE, and RRS. Discriminative ability and calibration were not improved by adaption of the algorithms according to EULAR recommendations. Up to 80% of CV events occurred in patients at “low risk” and up to 93% of CV events in patients at “low-intermediate risk”.

Conclusions

Adaption of the CV risk algorithms according to EULAR indications did not provide improvement in discriminative ability and calibration in patients with PsA.

Risk of myocardial infarction with use of selected non-steroidal anti-inflammatory drugs in patients with spondyloarthritis and osteoarthritis

OBJECTIVES

Spondyloarthritis (SpA) is associated with an increased risk of myocardial infarction (MI) due to underlying inflammation and possibly due to medications such as certain non-steroidal anti-inflammatory drugs (NSAIDs). We sought to describe MI risk among patients with SpA who were prescribed NSAIDs, and to compare the pattern of risk in SpA with that in osteoarthritis (OA).

METHODS

Nested case-control studies were performed using The Health Improvement Network (THIN). Underlying cohorts included adults with incident SpA or OA who had >1 NSAID prescription and no history of MI. Within each cohort, we matched each MI case to four controls without MI. NSAID use was categorised as: (a) current (prescription date 0-180 days prior to index date), (b) recent (181-365 days) or (c) remote (>365 days). We performed conditional logistic regression to compare the odds of current or recent NSAID use relative to remote use of any NSAID, considering diclofenac and naproxen specifically.

RESULTS

Within the SpA cohort of 8140 and the OA cohort of 244 339, there were 115 and 6287 MI cases, respectively. After adjustment, current diclofenac use in SpA was associated with an OR of 3.32 (95% CI 1.57 to 7.03) for MI. Naproxen was not associated with any increase (adjusted OR 1.19, 95% CI 0.53 to 2.68). A ratio of ORs for SpA/diclofenac relative to OA/diclofenac was 2.64 (95% CI 1.24 to 5.58).

CONCLUSIONS

MI risk in SpA is increased among current users of diclofenac, but not naproxen. The MI risk with diclofenac in SpA appears to differ from that in OA.

Cardiovascular risk factors predicting cardiac events are different in patients with rheumatoid arthritis, psoriatic arthritis, and psoriasis

OBJECTIVES

Increased cardiovascular risk in rheumatoid arthritis (RA) is well established. Examining traditional cardiovascular risk factors alone underestimates cardiovascular risk in RA. Systematic inflammation, measured by erythrocyte sedimentation rate or C-reactive protein is also a major risk factor. However, the contribution of traditional cardiovascular risk factors (such as obesity and hyperlipidaemia) compared to inflammation is uncertain in psoriatic arthritis (PsA) and RA. We examine the incidence of major adverse cardiac events (MACE) among patients with RA, PsA psoriasis, and controls adjusting for risk factors, inflammation and disease modifying anti-rheumatic drug treatment, to better define cardiovascular risk.

METHODS

Using the Secure Anonymised Information Linkage databank, comprising routinely collected Welsh health data from 1999 to 2013, the incidence and first occurrence of a MACE in individuals with RA (n = 8650), PsA (n = 2128) and psoriasis (n = 24,630) compared to controls (n = 11,87,706) was investigated.

RESULTS

Traditional cardiovascular risk factors are higher in RA, PsA and psoriasis than controls. After adjusting for these factors, additional cardiovascular risk was only significantly increased in female RA patients (HR = 1.3; 95% CI: 1.0-1.7; p = 0.05) and psoriasis (HR = 1.2; 95% CI: 1.0-1.4; p = 0.02) but not statistically significant for PsA (HR = 1.5; 95% CI: 0.9-2.5; p = 0.13). ESR and CRP were increased in patients with RA but not in patients with psoriasis.

CONCLUSION

Additional increased cardiovascular risk was observed in female RA and psoriasis but not PsA. Systematic inflammation is higher in RA but not psoriasis, indicating that there are varying mediators of cardiovascular risk across these conditions.

Characteristic and Outcome of Psoriatic Arthritis Patients with Hyperuricemia

OBJECTIVE

To determine the characteristics of patients with psoriatic arthritis (PsA) who have hyperuricemia (HUC) and their outcomes, especially cardiovascular (CVD) and kidney diseases.

METHODS

Patients have been followed prospectively at the PsA clinic according to a standard protocol at 6- to 12-month intervals. We defined HUC in men > 450 µmol/l or women > 360 µmol/l. We matched patients with HUC based on sex and age ± 5 years with normal uric acid patients. Demographics information and disease characteristics were reviewed. Outcomes of patients with HUC, especially CVD and kidney diseases, were recorded. Conditional logistic regression was performed to determine factors independently associated with HUC in patients with PsA.

RESULTS

There were 325 (31.9%) out of 1019 patients with PsA who had HUC. Of these, 318 cases were matched to 318 controls. There were 11 (3.4%) out of 325 patients with HUC who had gout. Patients with HUC had longer disease duration and a higher Psoriasis Area and Severity Index. They had more concurrent comorbidities, including CVD and metabolic diseases, as well as higher prevalence of kidney stones and higher creatinine. Only 1 patient with HUC was treated with allopurinol at first evaluation visit and 7 patients during followup. Over the followup, 163 of the 318 patients had persistent HUC (pHUC) for more than 2 visits. Patients with pHUC developed more myocardial infarction, heart failure, and renal impairment. Multivariate analysis showed an association between pHUC, PsA disease duration, and obesity.

CONCLUSION

HUC is common in patients with PsA, especially in those with longer disease duration and obesity. Proper control of HUC and metabolic diseases may play a preventive role in improving PsA outcomes.

Underestimation of Risk of Carotid Subclinical Atherosclerosis by Cardiovascular Risk Scores in Patients with Psoriatic Arthritis

Objective.

To test the performances of established cardiovascular (CV) risk scores in discriminating subclinical atherosclerosis (SCA) in patients with psoriatic arthritis.

Methods.

These scores were calculated: Framingham risk score (FRS), QRISK2, Systematic COronary Risk Evaluation (SCORE), 10-year atherosclerotic cardiovascular disease risk algorithm (ASCVD) from the American College of Cardiology and the American Heart Association, and the European League Against Rheumatism (EULAR)–recommended modified versions (by 1.5 multiplication factor, m-). Carotid intima-media thickness > 0.9 mm and/or the presence of plaque determined by ultrasound were classified as SCA+.

Results.

We recruited 146 patients [49.4 ± 10.2 yrs, male: 90 (61.6%)], of whom 142/137/128/118 patients were eligible to calculate FRS/QRISK2/SCORE/ASCVD. Further, 62 (42.5%) patients were SCA+ and were significantly older, with higher systolic blood pressure and higher low-density lipoprotein cholesterol (all p < 0.05). All CV risk scores were significantly higher in patients with SCA+ [FRS: 7.8 (3.9–16.5) vs 2.7 (1.1–7.8), p < 0.001; QRISK2: 5.5 (3.1–10.2) vs 2.9 (1.2–6.3), p < 0.001; SCORE: 1 (0–2) vs 0 (0–1), p < 0.001; ASCVD: 5.6 (2.6–12.4) vs 3.4 (1.4–6.1), p = 0.001]. The Hosmer-Lemeshow test revealed moderate goodness of fit for the 4 CV scores (p ranged from 0.087 to 0.686). However, of the patients with SCA+, those identified as high risk were only 44.1% (by FRS > 10%), 1.8% (QRISK2 > 20%), 10.9% (SCORE > 5%), and 43.6% (ASCVD > 7.5%). By applying the EULAR multiplication factor, 50.8%/14.3%/14.5%/54.5% of the patients with SCA+ were identified as high risk by m-FRS/m-QRISK2/m-SCORE/m-ASCVD, respectively. EULAR modification increased the sensitivity of FRS and ASCVD in discriminating SCA+ from 44% to 51%, and 44% to 55%, respectively.

Conclusion.

All CV risk scores underestimated the SCA+ risk. EULAR–recommended modification improved the sensitivity of FRS and ASCVD only to a moderate level.

Incidence and Prevalence of Cardiovascular Risk Factors Among Patients With Rheumatoid Arthritis, Psoriasis, or Psoriatic Arthritis

OBJECTIVE

To estimate prevalence and incidence of cardiovascular (CV) risk factors of hypertension, diabetes mellitus, hyperlipidemia, and obesity in patients with rheumatoid arthritis (RA), psoriasis, or psoriatic arthritis (PsA).

METHODS

Patients with RA, psoriasis, or PsA were identified based on medical and pharmacy claims from the MarketScan claims databases from January 1, 2002 through December 31, 2014. Primary outcomes included age- and sex-standardized prevalence of CV risk factors during the 12 months preceding diagnosis date and incidence rates per 1,000 patient-years, with 95% confidence intervals (95% CIs) during followup.

RESULTS

Prevalence for RA, psoriasis, and PsA cohorts for hypertension was 18.6% (95% CI 18.3-18.8), 16.6% (95% CI 16.3-17.0), and 19.9% (95% CI 19.4-20.4), respectively; for diabetes mellitus 6.2% (95% CI 6.1-6.4), 6.3% (95% CI 6.0-6.5), and 7.8% (95% CI 7.4-8.2); for hyperlipidemia 9.9% (95% CI 9.7-10.1), 10.4% (95% CI 10.2-10.7), and 11.6% (95% CI 11.2-12.0); and for obesity 4.4% (95% CI 4.2-4.6), 3.8% (95% CI 3.5-4.0), and 6.0% (95% CI 5.6-6.5). Incidence rates per 1,000 patient-years during followup for RA, psoriasis, and PsA cohorts, respectively, for hypertension were 74.0 (95% CI 72.5-75.5), 68.2 (95% CI 65.9-70.4), and 79.8 (95% CI 76.3-83.3); for diabetes mellitus 10.6 (95% CI 10.1-11.1), 13.0 (95% CI 12.1-13.8), and 14.7 (95% CI 13.5-16.0); for hyperlipidemia 40.3 (95% CI 39.4-41.3), 47.1 (95% CI 45.4-48.7), and 52.0 (95% CI 49.6-54.3); and for obesity 24.4 (95% CI 23.4-25.4), 26.4 (95% CI 25.0-27.8), and 32.9 (95% CI 30.6-35.2).

CONCLUSION

Patients with RA, psoriasis, and PsA have high prevalence and incidence of CV risk factors, suggesting the need for risk factor monitoring of these patients.

Cardiometabolic Disorders in Psoriatic Disease

PURPOSE OF REVIEW

Patients with psoriasis and psoriatic arthritis, collectively termed psoriatic disease (PsD), are at an increased risk of developing cardiovascular diseases (CVD). The purpose if this manuscript is to review recent evidence about the epidemiology and underlying mechanisms of CVD in psoriatic patients and approaches to improve the management of these comorbidities.

RECENT FINDINGS

Studies have shown that CVD risk is independent of traditional cardiovascular risk factors and is related to the systemic inflammatory nature of PsD. The use of surrogate markers, such as imaging of subclinical atherosclerosis, allows detection of patients at high cardiovascular risk before the occurrence of clinical events. These modalities could be clinically useful as clinical cardiovascular risk algorithms, such as the Framingham Risk Score, and have been shown to underestimate the actual cardiovascular risk in patients with PsD. Additional challenges related to the management of CVD in psoriatic patients include the underdiagnosis and undertreatment of traditional cardiovascular risk factors in rheumatology, dermatology and primary care setting. Effective measures used to control PsD, such as tumour necrosis factor inhibitors and methotrexate, has been associated with reduced cardiovascular risk in psoriatic patients. These findings highlight the importance of controlling disease activity as potential target that could lead to reduced cardiovascular risk. Together this highlights the importance of optimization of cardiovascular risk stratification and management of cardiovascular risk factors in patients with PsD.

Inhibition of Interleukin 17-A but not Interleukin-17F Signaling Lowers Blood Pressure and Reduces End-organ Inflammation in Angiotensin II-induced Hypertension

•

Hypertension is associated with an increase in T-cell–derived cytokines such IL-17A and IL-17F.

•

Monoclonal antibodies to IL-17A, IL-17F, IL-17RA, or isotype control antibodies (IgG1) were administered twice weekly during the last 2 weeks of a 4-week angiotensin II infusion protocol in mice.

•

Antibodies to IL-17A or IL-17RA, but not IL-17F, lowered blood pressure by 30 mm Hg, attenuated renal and vascular inflammation, and reduced renal transforming growth factor beta levels (a marker of renal fibrosis) compared with control IgG1 antibodies. All 3 experimental antibodies blunted the progression of albuminuria.

•

Monoclonal antibodies to IL-17A or IL-17RA may be a useful adjunct treatment for hypertension and the associated end-organ dysfunction.

Inflammatory cytokines play a major role in the pathophysiology of hypertension. The authors previously showed that genetic deletion of interleukin (IL)-17A results in blunted hypertension and reduced renal/vascular dysfunction. With the emergence of a new class of monoclonal antibody–based drugs for psoriasis and related autoimmune disorders that target IL-17 signaling, the authors sought to determine whether these antibodies could also reduce blood pressure, renal/vascular inflammation, and renal injury in a mouse model of hypertension. The authors show that antibodies to IL-17A or the IL-17RA receptor subunit, but not IL-17F, may be a novel adjunct treatment for hypertension and the associated end-organ dysfunction.

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

Patients with rheumatoid arthritis (RA) and other inflammatory joint disorders (IJD) have increased cardiovascular disease (CVD) risk compared with the general population. In 2009, the European League Against Rheumatism (EULAR) taskforce recommended screening, identification of CVD risk factors and CVD risk management largely based on expert opinion. In view of substantial new evidence, an update was conducted with the aim of producing CVD risk management recommendations for patients with IJD that now incorporates an increasing evidence base. A multidisciplinary steering committee (representing 13 European countries) comprised 26 members including patient representatives, rheumatologists, cardiologists, internists, epidemiologists, a health professional and fellows. Systematic literature searches were performed and evidence was categorised according to standard guidelines. The evidence was discussed and summarised by the experts in the course of a consensus finding and voting process. Three overarching principles were defined. First, there is a higher risk for CVD in patients with RA, and this may also apply to ankylosing spondylitis and psoriatic arthritis. Second, the rheumatologist is responsible for CVD risk management in patients with IJD. Third, the use of non-steroidal anti-inflammatory drugs and corticosteroids should be in accordance with treatment-specific recommendations from EULAR and Assessment of Spondyloarthritis International Society. Ten recommendations were defined, of which one is new and six were changed compared with the 2009 recommendations. Each designated an appropriate evidence support level. The present update extends on the evidence that CVD risk in the whole spectrum of IJD is increased. This underscores the need for CVD risk management in these patients. These recommendations are defined to provide assistance in CVD risk management in IJD, based on expert opinion and scientific evidence.

Rates of Cardiovascular Disease and Major Adverse Cardiovascular Events in Patients With Psoriatic Arthritis Compared to Patients Without Psoriatic Arthritis

BACKGROUND

Few studies report estimates of cardiovascular disease (CVD) or major adverse cardiovascular events (MACE) in patients with psoriatic arthritis (PsA).

OBJECTIVE

To estimate rates of incident CVD and MACE in patients with PsA compared to patients without PsA.

METHODS

Using the Clinical Practice Research Datalink, we conducted 2 cohort studies of patients with PsA compared to patients without PsA or psoriasis matched on age, sex, general practice, and calendar time: 1 study of CVD and 1 study of MACE. In each study, we excluded patients who had a study outcome before cohort entry. Cases were patients with a first-time diagnosis of CVD or MACE recorded during follow-up. We estimated incidence rates (IRs) and incidence rate ratios (IRRs) with 95% confidence intervals (95% CI) and stratified results in the PsA cohort by exposure to systemic PsA treatments.

RESULTS

The IR of CVD was higher in the patients with PsA compared to those without PsA (12.8/1000 person-years [PYs] [95% CI, 11.9-13.7] and 9.6/1000 PYs [95% CI, 9.3-9.0]; IRR, 1.33 [95% CI, 1.23-1.44]). The IR of MACE was slightly higher in the PsA compared to the non-PsA cohort (4.6/1000 PYs [95% CI, 4.1-5.1] and 3.5/1000 PYs [95% CI, 3.4-3.7]; IRR, 1.30 [95% CI, 1.15-1.47]). Among the patients with PsA, IRs were higher for those who received PsA treatments for both outcomes but did not differ significantly by type of treatment received.

CONCLUSIONS

The rates of CVD and MACE were slightly higher in the patients with PsA compared to the patients without PsA. Among the patients with PsA, rates of both outcomes were higher among those who received prescriptions for systemic PsA treatments.
