Increased risk of cardiovascular and cerebrovascular diseases in individuals with ankylosing spondylitis: a population-based study

Risk of cardiovascular disease with high-dose versus low-dose use of non-steroidal anti-inflammatory drugs in ankylosing spondylitis

OBJECTIVE

To investigate the risk of cardiovascular disease (CVD) associated with increasing dose of a non-steroidal anti-inflammatory drug (NSAID) in patients with ankylosing spondylitis (AS).

METHODS

Using the Korean National Health Insurance database, patients newly diagnosed with AS without prior CVD between 2010 and 2018 were included in this nationwide cohort study. The primary outcome was CVD, a composite outcome of ischaemic heart disease, stroke or congestive heart failure. Exposure to NSAIDs was evaluated using a time-varying approach. The dose of NSAIDs was considered in each exposure period. Cox proportional hazard regression was used to investigate the risk of CVD associated with NSAID use.

RESULTS

Of the 19 775 patients (mean age, 36 years; 75% were male), 19 706 received NSAID treatment. During follow-up period of 98 290 person-years, 1663 cases of CVD occurred including 1157 cases of ischaemic heart disease, 301 cases of stroke and 613 cases of congestive heart failure. Increasing dose of NSAIDs was associated with incident CVD after adjusting for confounders (adjusted HR (aHR) 1.10; 95% CI 1.08 to 1.13). Specifically, increasing dose of NSAIDs was associated with incident ischaemic heart disease (aHR 1.08; 95% CI 1.05 to 1.11), stroke (aHR 1.09; 95% CI 1.04 to 1.15) and congestive heart failure (aHR 1.12; 95% CI 1.08 to 1.16). The association between NSAID dose and higher CVD risk was consistent in different subgroups.

CONCLUSION

In a real-world AS cohort, higher dose of NSAID treatment was associated with a higher risk of CVD, including ischaemic heart disease, stroke and congestive heart failure.

HLA-B27, axial spondyloarthritis and survival

INTRODUCTION

Ankylosing spondylitis (AS), and carriage of HLA-B27 gene in otherwise healthy individuals, are reportedly associated with increased mortality. We evaluated this hypothesis, using data from both a 35-year AS follow-up study and UK Biobank data.

METHODS

In 1985, 363 members of the Swiss AS Patient Society and 806 relatives were screened clinically and then radiographically for AS/axial spondyloarthritis (axSpA). Life expectancy was analysed in 377 axSpA patients having available pelvic radiographs and HLA-B27 status, comparing with matched Swiss population data. Survival in relation to HLA-B27 status in the general population was studied in UK Biobank European-ancestry participants (n=407 480, n=30 419 deaths).

RESULTS

AS patients have increased standardised mortality rate (SMR) compared with the general population (1.37, 95% CI 1.11 to 1.62). This increase was significant for HLA-B27-positive AS (SMR 1.38, 95% CI 1.11 to 1.65). Shortened life expectancy was observed among both HLA-B27-positive AS women (SMR 1.77, 95% CI 1.09 to 2.70) and men (SMR 1.31, 95% CI 1.02 to 1.59). Patients with non-radiographic axSpA (nr-axSpA) had significantly lower SMR: 0.44 (95% CI 0.23 to 0.77), compared with the general population. In the UK Biobank European-ancestry population cohort, HLA-B27 carriage was not significantly associated with any change in mortality (HR 1, 95% CI 0.97 to 1.1, p=0.349, adjusted by sex), in either males (HR 1, 95% CI 0.98 to 1.1, p=0.281) or females (HR 0.96, 95% CI 0.9 to 1, p=0.232), and no increase in vascular disease mortality was observed.

DISCUSSION

AS patients, but not nr-axSpA patients, have a significantly shortened life expectancy. Increased mortality is particularly significant among women with HLA-B27-positive AS. HLA-B27 carriage in the European-ancestry general population does not influence survival, or the risk of death due to vascular disease.

Acute spinal cord infarction secondary to ankylosing spondylitis: a case report and literature review

Introduction

Spinal cord infarction secondary to ankylosing spondylitis is a rare but severe disorder.

Case presentation

Here we present a case of acute spinal cord infarction in a 54 years-old man with a medical history of ankylosing spondylitis, scoliosis, and hypotension. The patient complained of a sudden onset of lower limb weakness. A physical examination showed that he suffered from a dissociative sensory disorder, paralysis, and concomitant sphincter disturbances. After undergoing a whole-spine MRI, he was diagnosed with an acute ischemic injury from T2 to T5. As he did not treat his ankylosing spondylitis, it later caused a spinal deformity, making the lumbar puncture technically challenging. However, using Taylor's approach, a CSF sample was successfully obtained. A CSF biochemical test ruled out myelitis, NMOSD, and MS. After receiving treatment with low-molecular-weight heparin, atorvastatin calcium, and methylprednisolone, his sphincter function gradually recovered, but his strength was only partially restored.

Conclusion

Although this is a rare entity, it is necessary for physicians to consider it when evaluating patients with a sudden loss of sensation and strength in their lower limbs.

Is there a change in the appropriateness of admission after patients were admitted? Evidence from four county hospitals in rural China

Objective

This study aims to investigate the changes in admission appropriateness after patients were admitted and provide a reference for physicians to make admission decisions and for the supervision of medical service behavior by the medical insurance regulatory department.

Methods

Medical records of 4,343 inpatients were obtained based on the largest and most capable public comprehensive hospital in four counties in central and western China for this retrospective study. The binary logistic regression model was employed to examine the determinants of changes in admission appropriateness.

Results

Nearly two-in-thirds (65.39%) of the 3,401 inappropriate admissions changed to appropriate at discharge. Age, type of medical insurance, medical service type, severity of the patient upon admission, and disease category were found to be associated with the changes in the appropriateness of admission. Older patients (OR = 3.658, 95% CI [2.462-5.435]; P < 0.001) were more likely to go from "inappropriate" to "appropriate" than younger counterparts. Compared with circulatory diseases, the case evaluated as "appropriate" at discharge was more frequent in the urinary diseases (OR = 1.709, 95% CI [1.019-2.865]; P = 0.042) and genital diseases (OR = 2.998, 95% CI [1.737-5.174]; P < 0.001), whereas the opposite finding was observed for patients with respiratory diseases (OR = 0.347, 95% CI [0.268-0.451]; P < 0.001) and skeletal and muscular diseases (OR = 0.556, 95% CI [0.355-0.873]; P = 0.011).

Conclusions

Many disease characteristics gradually emerged after the patient was admitted, thus the appropriateness of admission changed. Physicians and regulators need to take a dynamic view of disease progression and inappropriate admission. Aside from referring to the appropriateness evaluation protocol (AEP), they both should pay attention to individual and disease characteristics to make a comprehensive judgment, and strict control and attention should be paid to the admission of respiratory, skeletal, and muscular diseases.

Increased risk of stroke among patients with ankylosing spondylitis: A systematic review and meta-analysis

BACKGROUND

Ankylosing spondylitis is a chronic inflammatory disease that is associated with adverse cardiovascular events. This study aimed to determine the relationship between ankylosing spondylitis and the risk of stroke.

METHODS

A systematic literature search in PubMed/MEDLINE, Scopus, and Web of Science were conducted from inception to December 2021 to identify relevant articles investigating the risk of stroke in patients with ankylosing spondylitis. A random-effects model (DerSimonian and Laird) was used to estimate a pooled hazard ratio (HR) and 95% confidence intervals (CI). Meta-regression based on the length of follow-up and subgroup analysis based on the type of stroke, study location, and year of publication to investigate the source of heterogeneity.

RESULTS

A total of eleven studies comprising 1.7 million participants were included in this study. Pooled analysis showed a significantly increased stroke risk (56%) among patients with ankylosing spondylitis (HR: 1.56, 95% CI 1.33-1.79). Subgroup analysis revealed a higher risk of ischemic stroke among patients with ankylosing spondylitis (HR: 1.46, 95% CI: 1.23-1.68). However, meta-regression analysis showed no association between the duration of ankylosing spondylitis and stroke incidence (Coef=-0.0010, P=0.951).

CONCLUSION

This study reveals that ankylosing spondylitis was associated with an increased risk of suffering a stroke. Management of cerebrovascular risk factors and the control of systemic inflammation should be considered in patients with ankylosing spondylitis.

Correlation between Endophthalmitis and Stroke Development in Ankylosing Spondylitis Patients: A Population-Based Cohort Study

BACKGROUND

This cohort study aimed to research the correlation between endophthalmitis and stroke development in ankylosing spondylitis (AS) patients by reviewing National Health Insurance Research Database (NHIRD) data.

METHODS

This study obtained data from the NHIRD over a sixteen-year period. The primary outcome was stroke development. We used Fisher's exact test and Pearson's chi-squared test to analyze the variables. We investigated the risk factors for disease development using Cox regression analyses. We compared the cumulative incidence of stroke using Kaplan-Meier analysis.

RESULTS

The study cohort included 549 patients with AS and endophthalmitis, while the comparison cohort included 2196 patients with AS but without endophthalmitis. The stroke development was increased in the study cohort (adjusted hazard ratio, 1.873; p ≤ 0.001). The total stroke development in the study cohort and the comparison cohort was 1724.44 per 100,000 person-years and 1085.11 per 100,000 person-years, respectively (adjusted hazard ratio, 1.873; 95% confidence interval, 1.776-2.022; p < 0.001). Our study cohort showed an increased stroke rate.

CONCLUSIONS

Our studies showed that endophthalmitis increases the risk of stroke in AS patients and endophthalmitis is an independent risk factor for stroke in AS patients. Nonetheless, advanced studies that thoroughly investigate the correlation between endophthalmitis and stroke in AS patients are needed to validate our findings.

Mortality in Ankylosing Spondylitis According to Treatment: A Nationwide Retrospective Cohort Study of 5,900 Patients From Israel

OBJECTIVE

In this large population-based study we aimed: 1) to assess mortality in patients with ankylosing spondylitis (AS) compared to the general population, considering demographics, comorbidities, and treatment, and 2) to assess factors associated with mortality within patients with AS.

METHODS

This study was designed as a retrospective cohort study using the electronic database of the largest health maintenance organization in Israel. All patients with AS diagnosed between 2002 and 2018 were included. Controls were matched by age, sex, clinic, and enrollment time. Follow-up continued until death or the end of the study.

RESULTS

The study comprised 5,930 AS patients and 29,018 matched controls who were followed up for a median period of 7.5 years. There were 667 deaths within the AS cohort and 2,919 deaths within controls; the mean age at death was 76.9 years and 77.1 years, respectively (P = 0.74). A total of 3,249 AS patients (54.8%) were treated only with nonsteroidal antiinflammatory drugs, 1,760 (29.7%) were treated with tumor necrosis factor inhibitors (TNFi), and 1,687 (28.4%) with disease-modifying antirheumatic drugs (DMARDs). Mortality rates were increased among AS patients compared to controls, with an age- and sex-adjusted hazard ratio (HR) of 1.19 (95% confidence interval [95% CI] 1.10-1.30). The association was significant for men (HR 1.15 [95% CI 1.04-1.27]) and women (HR 1.32 [95% CI 1.13-1.54]), and after adjusting for background comorbidities (HR 1.14 [95% CI 1.05-1.24]). AS patients treated with TNFi or with a combination of TNFi and DMARDs did not have significant difference in mortality rates compared to controls (HR 0.67 [95% CI 0.38-1.18] and HR 0.93 [95% CI 0.69-1.25], respectively). Age, male sex, mean C-reactive protein (CRP) levels and general comorbidities were predictors of mortality within the AS cohort.

CONCLUSION

AS patients had an increased mortality risk compared to the general population after adjusting for age, sex, and baseline comorbidities. AS patients treated with TNFi did not demonstrate excess mortality compared to matched controls. Within the AS cohort, age, male sex, background comorbidities, and higher CRP levels were identified as risk factors for mortality.

Factors Associated with the Risk of Major Adverse Cardiovascular Events in Patients with Ankylosing Spondylitis: A Nationwide, Population-Based Case-Control Study

Background: Potential risk factors for major adverse cardiovascular events (MACE) in patients with ankylosing spondylitis (AS) requiring medical therapy should be investigated. Methods: We identified newly diagnosed AS patients without previous MACE from 2004 to 2012 using the National Health Insurance Research Database, matched MACE cases with non-MACE controls at a 1:4 ratio for age, gender, AS duration, and index date, and included 947 AS patients with MACE and 3896 matched controls for final analyses. By using conditional logistic regression analyses, we examined the associations of MACE with low income, urbanisation, comorbidities, common extra-articular manifestations (EAM), and medications, including nonsteroidal anti-inflammatory drugs (NSAID) of three categories (traditional NSAIDs, selective cyclooxygenase-2 inhibitors (COX-2i), and preferential COX-2is) with their annual cumulative defined daily dose (cDDD) within a year before MACE development. Results: MACE development was associated with the use of selective COX-2is (especially with annual cDDD > 132) and corticosteroids, residence in rural regions, and well-known associated comorbidities, but not with the use of traditional NSAIDs, preferential COX-2i, biologics, methotrexate, sulfasalazine, and common EAMs. Conclusions: The risk factors of MACE in newly diagnosed AS patients include residence in rural regions, well-known associated comorbidities, and the use of corticosteroids and selective COX-2is. A major limitation was the lack of information on individual lifestyle patterns and disease activity.

Increased risks of aortic regurgitation and atrial fibrillation in radiographic axial spondyloarthritis patients: a 10-year nationwide cohort study

Background:

To compare the incidences of aortic regurgitation, atrial fibrillation (AF), and atrioventricular (AV) block II–III between radiographic axial spondyloarthritis (r-axSpA) patients and the general population (GP).

Methods:

National Health Insurance Services data were used. R-axSpA patients (N = 8877) and the age- and sex-matched GP (N = 26,631) were followed from August 2006 to December 2019. Incidence rates and standardized incidence ratios (SIRs) of aortic regurgitation, AF, and AV block II–III were compared between these groups. Ten-year incidence rates and hazard ratios (HRs) were calculated by the Kaplan–Meier method and Cox regression analysis.

Results:

Incidence rates of aortic regurgitation, AV block II–III, and AF in the r-axSpA group were 0.42, 0.21, and 4.0 per 1000 person-years (PYs), respectively. In the r-axSpA group, the SIR for aortic regurgitation was highest among 40- to 49-year-old men (4.11). Incidence rates of aortic regurgitation and AF were higher in the r-axSpA group than in the GP group (0.42 versus 0.18 per 1000 PYs 4.00 versus 3.13 per 1000 PYs, both p < 0.001, respectively), whereas the difference was insignificant for AV block II–III (0.21 versus 0.14 per 1000 PYs, p = 0.222). In multivariate analysis, r-axSpA was associated with a higher hazard (risk) for the development of aortic regurgitation and AF [HR (95% confidence interval) = 2.55 (1.49–4.37) and 1.20 (1.04–1.39), respectively], but the difference was insignificant for AV block II–III [HR (95% confidence interval) = 1.17 (0.59–2.31)].

Conclusions:

Compared with the GP, r-axSpA patients are at increased risk of aortic regurgitation and AF, but not AV block II–III. These patients should be carefully monitored for occurrence of aortic regurgitation and AF.

The effect of exercise training programs with aerobic components on C-reactive protein, erythrocyte sedimentation rate and self-assessed disease activity in people with ankylosing spondylitis: A systematic review and meta-analysis

AIM

To examine the effect of exercise training programs with aerobic components on C-reactive protein, erythrocyte sedimentation rate and self-assessed disease activity in people with ankylosing spondylitis compared to non-aerobic rehabilitation.

METHODS

A systematic review was undertaken of PubMED, Cochrane Library, Embase and Web of Science databases. Articles evaluating the effect of exercise training programs with aerobic components on C-reactive protein, erythrocyte sedimentation rate or Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) in adults (>17 years) with ankylosing spondylitis were included. Control groups were defined as non-aerobic rehabilitation, including usual care or physiotherapy.

RESULTS

Thirteen articles met inclusion criteria for qualitative and meta-analysis, involving 366 participants undertaking exercise and 361 controls. Exercise programs included modalities such as running, aerobic walking and swimming, and were between 3 weeks and 3 months in duration. Exercise programs significantly reduced C-reactive protein (weighted mean difference [WMD]: -1.09; 95% CI: -2.08 to -0.10; P = .03; n = 5) and BASDAI (WMD: -0.78; 95% CI: -0.98 to -0.58; P < .001; n = 13) compared to non-aerobic rehabilitation. BASDAI subgroup analysis revealed greater improvements compared to usual care than structured physiotherapy. Exercise programs did not reduce erythrocyte sedimentation rate (WMD: 0.16; 95% CI: -2.15 to 2.47; P = .89; n = 4).

CONCLUSION

Exercise training programs with aerobic components reduced C-reactive protein and improved self-assessed disease activity in people with ankylosing spondylitis. Further research is required to investigate the effects of differing aerobic exercise modes, intensities and durations.

Systolic and Diastolic Cardiac Functions in Juvenile Spondyloarthropathies

BACKGROUND/OBJECTIVE

Juvenile spondyloarthropathies (JSpAs) are a group of inflammatory diseases characterized by asymmetric peripheral arthritis (especially in lower extremities), axial skeleton involvement, and enthesitis. Although cardiovascular findings of inflammatory diseases such as juvenile systemic lupus erythematosus (SLE) and juvenile scleroderma (SD) are well documented, there are only a few studies assessing the cardiovascular consequences of JSpA in the literature.

METHODS

Forty patients with JSpA and 20 healthy controls were included into this cross-sectional study. Cardiac functions of the participants were evaluated by conventional echocardiography and pulse-wave (PW) tissue Doppler.

RESULTS

The patients with JSpA had higher mitral lateral S (p = 0.005) and E' wave (p < 0.001), tricuspid A' wave (p = 0.03), ejection fraction (p = 0.03) and shortening fraction (p = 0.01) than the control patients. In contrast, the patients with JSpA had lower left ventricle MPI (p = 0.01) and the ratio of tricuspid E'/A' waves (p = 0.05). Patients with enthesitis detected on magnetic resonance imaging had lower ejection fraction (p = 0.05), the ratio of E/A waves (p = 0.03) and had higher Mitral lateral A' wave (p = 0.01) than those without. There was a significant inverse correlation between the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and PW transmitral A velocity (r = -0.256, p = 0.03), the BASDAI score and tricuspid annular plane systolic excursion (r = -0.301, p = 0.04), the BASDAI score and the ratio of E/E' waves (r = -0.276, p = 0.02), and the Juvenile Spondyloarthritis Disease Activity Index and PW transmitral A velocity (r = -0.246, p = 0.04).

CONCLUSIONS

In this study, we report the possible early signs of RV diastolic dysfunction and possible association between magnetic resonance imaging-confirmed enthesitis and lower LV systolic functions. Early identification of cardiac dysfunctions can help with prevention of long-term cardiovascular complications.

The Risk of Cardiovascular Diseases in Axial Spondyloarthritis. Current Insights

There is an increased cardiovascular (CV) risk in axial spondyloarthritis (axSpA), leading to increased CV mortality and morbidity in these patients. The factors that may explain this enhanced CV risk in axSpA are multiple, including traditional CV risk factors such as smoking, but also the inflammatory process and probably the use of non-steroidal anti-inflammatory drugs (NSAIDs). The CV involvement of axSpA may be detected at an early and pre-clinical stage, using non-invasive techniques. While NSAIDs play a deleterious role in the CV risk of axSpA, TNF inhibitors seem to have a beneficial impact, but this remains to be demonstrated in specific clinical studies. More data are needed to determine the potential effects of IL-17 inhibitors on the CV risk of axSpA. CV comorbidity has been mainly assessed in the radiographic form of axSpA, while limited data are available in patients with the non-radiographic form. The current management of axSpA must consider this CV comorbidity according to the EULAR recommendations. Rheumatologists play a determinant role in the detection of CV risk and current management of these patients is focused on the control of disease activity, suppression of inflammation, screening for and management of traditional CV risk factors, as well as the restriction of NSAID use.

Angiotensin-Receptor Blockade Improves Inflammation and Endothelial Dysfunction in Ankylosing Spondylitis: ARB-AS Study

Cardiovascular (CV) disease is the leading cause of premature death in ankylosing spondylitis (AS). Atherosclerosis and AS share similar pathogenic mechanisms. The proven benefits of angiotensin-receptor blockers (ARBs) in atherosclerotic cardiovascular disease and their role in immune mediation provide strong rationale to investigate its impact with olmesartan on inflammation and endothelial dysfunction in AS. To investigate the effect of olmesartan on inflammation and endothelial dysfunction in AS. 40 AS patients were randomized to receive 24 weeks of treatment with olmesartan (10 mg/day, n  = 20) and placebo ( n  = 20) as an adjunct to existing stable antirheumatic drugs. Markers of endothelial function included the following: flow-mediated dilation (FMD) assessed by AngioDefender, endothelial progenitor cells (EPCs) estimated by flow cytometry, nitrite (nitric oxide surrogate), intracellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) and inflammatory measures including Bath ankylosing spondylitis disease activity index (BASDAI), ankylosing spondylitis disease activity score (ASDAS) and bath ankylosing spondylitis functional index (BASFI); erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP); proinflammatory cytokines (interleukin-1 [IL-1], IL-6, tumor necrosis factor-α [TNF-α]) and marker of oxidative stress- thiobarbituric acid reactive substances (TBARS) estimated at baseline and after treatment. Health assessment questionnaire disability index (HAQDI), 36-item short form survey (SF-36), and systematic coronary risk evaluation (SCORE) were estimated using standard tools. FMD improved significantly in the olmesartan group (5.83 ± 0.31% to 7.68 ± 0.27%, p  ≤  0.05) as compared with placebo (5.89 ± 0.35% to 6.04 ± 0.32%, p  = 0.33). EPC population, nitrite, VCAM-1, and TBARS levels improved significantly in olmesartan group as compared with placebo ( p ≤ 0.05). Olmesartan significantly decreased ASDAS, BASDAI, BASFI, ESR, CRP, IL-6, TNF-α, and SCORE as compared with placebo. HAQDI and SF-36 (PH) scores improved significantly in olmesartan group as compared with placebo. Olmesartan reduces inflammatory disease activity, improves quality of life (QOL), and decreases CV risk demonstrating the immunomodulatory, vasculoprotective, and cardioprotective potential of this drug in AS.

Valve Abnormalities, Risk Factors for Heart Valve Disease and Valve Replacement Surgery in Spondyloarthritis. A Systematic Review of the Literature

Objective: Evaluate the evidence on the abnormalities of the aortic root and heart valves, risk and prognostic factors for heart valve disease and valve replacement surgery in spondyloarthritis.

Methods: A systematic literature review was performed using Medline, EMBASE and Cochrane databases until July 2021. Prevalence, incidence, risk and prognostic factors for heart valve disease; dimension, morphology, and pathological abnormalities of the valves were analyzed. Patient characteristics (younger age, history of cardiac disease or longer disease duration) and period of realization were considered for the analysis. The SIGN Approach was used for rating the quality of the evidence of the studies.

Results: In total, 37 out of 555 studies were included. Overall, the level of evidence was low. The incidence of aortic insufficiency was 2.5–3.9‰. Hazard Ratio for aortic insufficiency was 1.8–2.0. Relative risk for aortic valve replacement surgery in ankylosing spondylitis patients was 1.22–1.46. Odds ratio for aortic insufficiency was 1.07 for age and 1.05 for disease duration. Mitral valve abnormalities described were mitral valve prolapse, calcification, and thickening. Aortic valve abnormalities described were calcification, thickening and an echocardiographic “subaortic bump.” Abnormalities of the aorta described were thickening of the wall and aortic root dilatation. The most common microscopic findings were scarring of the adventitia, lymphocytic infiltration, and intimal proliferation.

Conclusions: A higher prevalence and risk of aortic valve disease is observed in patients with ankylosing spondylitis. Studies were heterogeneous and analysis was not adjusted by potential confounders. Most studies did not define accurate outcomes and may have detected small effects as being statistically significant.

Proprotein convertase subtilisin/kexin type 9 in the dyslipidaemia of patients with axial spondyloarthritis is related to disease activity

OBJECTIVE

Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a serine protease that regulates cholesterol metabolism and has been linked to cardiovascular (CV) risk. The purpose of the present study was to examine whether PCSK9 levels are related to abnormalities in the lipid profile and the development of atherosclerosis that occurs in patients with axial SpA (axSpA).

METHODS

We performed a cross-sectional study that encompassed 545 individuals; 299 patients with axSpA and 246 statin use-matched controls. PCSK9 and standard lipid profiles were analysed in patients and controls. Carotid intima-media thickness (cIMT) and carotid plaques were assessed in patients. A multivariable analysis, adjusted for standard CV risk factors, was performed to evaluate the influence of PCSK9 on axSpA-related dyslipidaemia and subclinical carotid atherosclerosis.

RESULTS

Total cholesterol, high-density lipoprotein and low density lipoprotein cholesterol, lipoprotein (a) and apolipoprotein A1 were significantly lower in axSpA patients than controls. PCSK9 serum levels [β coefficient -44 ng/dl (95% CI -60, -27), P = 0.000] were also downregulated in axSpA patients after fully multivariable adjustment. ASDAS-CRP was found to be independently and significantly related to PCSK9 [β coefficient 10 ng/dl (95% CI 1, 18), P = 0.023] after analysing fully adjusted models that took age, sex and the rest of the lipid profile molecules into account. Whereas patients taking prednisone showed higher serum levels of PCSK9 [55 ng/ml (95% CI 24, 8), P = 0.001], those under anti-TNF-α therapies exhibited lower levels [β coefficient -26 ng/ml (95% CI -43, -9], P = 0.003].

CONCLUSION

PCSK9 is downregulated in patients with axSpA. Disease activity is positive and significantly related to PSCK9. Anti-TNF-therapy yields a reduction in PCSK9 serum levels.

Increased risk of valvular heart disease in patients with ankylosing spondylitis: a nationwide population-based longitudinal cohort study

Aims:

We aimed to evaluate the risk of valvular heart disease (VHD) among patients with ankylosing spondylitis (AS).

Methods:

This was a population-based cohort study utilizing the Longitudinal Health Insurance Research Database of the National Health Insurance in Taiwan. Patients with and without coding of newly diagnosed AS from 1999 to 2013 were assigned to the AS and non-AS groups, respectively. Primary outcome was the incidental risk of VHD. Multiple Cox regression was used to estimate the adjusted hazard ratio of VHD. Subgroup analysis and sensitivity tests were also conducted.

Results:

The AS group included 3780 patients, and 22,680 matched subjects without an AS diagnosis were identified as controls. The AS group had an increased risk of VHD compared with non-AS controls (adjusted hazard ratio: 1.63; 95% confidence interval: 1.43–1.86; p < 0.001). Subgroup analysis also revealed an increased risk of individual types of VHD, including aortic, mitral, and tricuspid valve disease. Patients in the AS group had a higher incidence of valve replacement surgery after the onset of VHD.

Conclusion:

Patients with AS had a significant risk of VHD compared to non-AS controls in this population-based cohort study. Screening for VHD may be needed in caring patients with AS. We suggest that echocardiography may be performed when patients are diagnosed with AS.

Association between ischemic stroke and seropositive rheumatoid arthritis in Korea: A nationwide longitudinal cohort study

The purpose of this longitudinal follow-up study was to investigate the risk of ischemic stroke nationwide in patients with seropositive rheumatoid arthritis (RA) and controls who were matched in age and sex. Patient data were collected from the National Health Insurance Service (NHIS) Health Screening (HEALS) cohort. Using the International Classification of Diseases code M05 (seropositive RA), with a prescription of any disease-modifying anti-rheumatic drug (DMARD), RA was identified. A total of 2,765 patients and 13,825 control subjects were included in our study. The 12-year incidence of ischemic stroke in each group was calculated using the Kaplan–Meier method. The risk ratio of ischemic stroke was estimated using Cox proportional hazards regression. Sixty-four patients (2.31%) in the seropositive RA group and 512 (3.70%) in the control group experienced ischemic stroke (P < 0.001) during the follow-up period. The hazard ratio of ischemic stroke in the seropositive RA group was 1.32 (95% confidence interval (CI), 1.02–1.73) after adjusting for age and sex. The adjusted hazard ratio of ischemic stroke in the seropositive RA group was 1.40 (95% CI, 1.07–1.82) after adjusting for demographics and comorbid medical disorders. According to the subgroup analysis, the hazard ratios of ischemic stroke risks in the female and hypertensive subgroups were 1.44 (95% CI, 1.05–1.97) and 1.66 (95% CI, 1.16–2.38), respectively. In the non-diabetes and non-dyslipidemia subgroups, the corresponding hazard ratios of ischemic stroke were 1.47 (95% CI, 1.11–1.95) and 1.43 (95% CI, 1.07–1.91). Seropositive RA patients have an increased risk of ischemic stroke. In female, hypertension, non-diabetes, and non-dyslipidemia RA subgroups, even without the traditional risk factors for stroke (except for hypertension), increased the risk, which could be potentially attributed to RA.

Myocardial Involvement in Rheumatic Disorders

PURPOSE OF REVIEW

Autoimmune rheumatic diseases (ARDs) affect 8% of the population and approximately 78% of patients are women. Myocardial disease in ARDs is the endpoint of various pathophysiologic mechanisms including atherosclerosis, valvular disease, systemic, myocardial, and/or vascular inflammation, as well as myocardial ischemia and replacement/diffuse fibrosis.

RECENT FINDINGS

The increased risk of CVD in ARDs leads to excess comorbidity not fully explained by traditional cardiovascular risk factors. It seems that the chronic inflammatory status typically seen in ARDs, promotes both the development of myocardial inflammation/fibrosis and the acceleration of atherosclerosis. CMR (cardio-vascular magnetic resonance) is the ideal imaging modality for the evaluation of cardiac involvement in patients with ARDs, as it can simultaneously assess cardiac function and characterize myocardial tissues with regard to oedema and fibrosis. Due to its high spatial resolution, CMR is capable of identifying various disease entities such as myocardial oedema /inflammation, subendocardial vasculitis and myocardial fibrosis, that are often missed by other imaging modalities, notably at an early stage of development. Although generally accepted guidelines about the application of CMR in ARDs have not yet been formulated, according to our experience and the available published literature, we recommend CMR in ARD patientS with new-onset heart failure (HF), arrhythmia, for treatment evaluation/change or if there is any mismatch between patient symptoms and routine non-invasive evaluation.

Increased Incidence of Stroke and Transient Ischemic Attack in Patients with Rheumatoid Arthritis and Ankylosing Spondylitis in Germany

BACKGROUND

As chronic inflammatory diseases may be associated with an increased risk of vascular events, the aim of the present study was to assess the incidence of stroke and transient ischemic attack (TIA) in patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS).

METHODS

Patients diagnosed with RA and AS in 1,262 general practices in Germany between 2000 and 2015 were selected. RA and AS patients were matched to patients without RA or AS using propensity scores based on age, sex, physician, co-diagnoses, and co-therapies. The Kaplan-Meier curves and Cox regression models were used to study the incidence of stroke and TIA as a function of RA and AS.

RESULTS

In the study population (N = 29,106; mean age 54.8 years; 65% women), 24,580 patients had RA and 4,526 had AS. RA was significantly associated with the stroke (hazard ratio [HR] = 1.42, confidence interval [CI]: 1.25-1.60) and TIA (HR = 1.69, CI: 1.46-1.95). The association between RA and stroke was strongest in the age group 18-40 years (HR = 3.45, CI: 1.30-9.18). The HR for stroke in AS was 1.41 (CI: 0.99-2.00) and for TIA 1.62 (1.08-2.44).

CONCLUSION

RA was significantly associated with stroke and TIA, with young patients being at a particularly increased risk. AS was tendentially associated with stroke and TIA.

Stroke risk in arthritis: A systematic review and meta-analysis of cohort studies

BACKGROUND AND OBJECTIVE

Stroke is a major contributor to the global burden of disease. Although numerous modifiable risk factors (RF) for stroke have been identified, some remain unexplained. Increasing studies have investigated stroke risk in arthritis, but their results are inconsistent. We aimed to synthesize, quantify, and compare the risk of stroke for the major types of arthritis in cohort studies by using a systematic review and meta-analysis approach.

METHODS

We searched Chinese and English databases to identify relevant studies from inception to April 30, 2020. Only studies adjusting at least for age and sex were included. We calculated pooled effect estimates for relative risk (RR) and 95% confidence interval (CI) and identified potential sources of heterogeneity and publication bias.

RESULTS

A total of 1,348 articles were retrieved, and after an preliminary screening of titles and abstracts, 69 were reviewed for full text, and finally, 32 met the criteria for meta-analysis. Stroke risk in arthritis was significantly increased in studies adjusting for age and sex (RR = 1.36, 95% CI: 1.27-1.46) and for at least one traditional risk factor (RR = 1.40, 95% CI: 1.28-1.54). The results of studies stratified by stroke subtype were consistent with the main finding (ischemic stroke: RR = 1.53, 95% CI: 1.32-1.78; hemorrhagic stroke: RR = 1.45, 95% CI: 1.15-1.84). In subgroup analysis by arthritis type, stroke risk was significantly increased in rheumatoid arthritis (RR = 1.38, 95% CI: 1.29-1.48), ankylosing spondylitis (RR = 1.49, 95% CI: 1.25-1.77), psoriatic arthritis (RR = 1.33, 95% CI: 1.22-1.45), and gout (RR = 1.40, 95% CI: 1.13-1.73) but not osteoarthritis (RR = 1.03, 95% CI: 0.91-1.16). Age and sex subgroup analyses indicated that stroke risk was similar by sex (women: RR = 1.47, 95% CI: 1.31-1.66; men: RR = 1.44, 95% CI: 1.28-1.61); risk was higher with younger age (<45 years) (RR = 1.46, 95% CI: 1.17-1.82) than older age (≥65 years) (RR = 1.17, 95% CI: 1.08-1.26).

CONCLUSIONS

Stroke risk was increased in multiple arthritis and similar between ischemic and hemorrhagic stroke. Young patients with arthritis had the highest risk.

Subclinical atherosclerotic disease in ankylosing spondylitis and non-radiographic axial spondyloarthritis. A multicenter study on 806 patients

OBJECTIVES

To compare the atherosclerosis disease burden between ankylosing spondylitis (AS) and non-radiographic (nr) axial spondyloarthritis (axSpA) and establish a model that allows to identify high-cardiovascular (CV) risk in axial spondyloarthritis patients.

METHODS

Cross-sectional study from the AtheSpAin cohort, a Spanish multicenter cohort aimed to study atherosclerosis in axSpA. Carotid ultrasound (US) was performed to determine the carotid intima-media wall thickness (cIMT) and detect the presence of carotid plaques. The European cardiovascular disease risk assessment model, the Systematic COronary Risk Evaluation (SCORE), was also applied.

RESULTS

A set of 639 patients with AS and 167 patients with nr-axSpA without history of CV events were recruited. AS patients were older showing more CV risk factors and higher values of C reactive protein and erythrocyte sedimentation rate (ESR) than those with nr-axSpA. However, no difference in the prevalence of carotid plaques or in the cIMT was found between both groups in the adjusted analysis. The percentage of patients reclassified from the low and moderate CV risk categories to the very high-risk category due to the presence of carotid plaques was comparable in AS and nr-axSpA (10.7% versus 10.1% and 40.5% versus 45.5%, respectively). A model containing age, BASFI and ESR applied to moderate risk axSpA patients identified 41% of these patients as having very high-risk patients with high specificity (88%).

CONCLUSION

The atherosclerosis burden is similar in nr-axSpA and AS. As occurred for AS, more than 40% of axSpA patients included in the category of moderate CV risk according to the SCORE are reclassified into very high risk after carotid US, and a clinically relevant proportion of them can be detected by applying a model containing age, BASFI and ESR.

Biomarkers of Cardiovascular Disease in Patients With Ankylosing Spondylitis

Objectives

This study aims to evaluate the inflammatory status and clinical and vascular alterations using tonometry and B-mode sonography in patients with ankylosing spondylitis (AS).

Patients and methods

The study included 71 AS patients (57 males, 14 females; mean age 40.1±10.8 years; range, 29 to 51 years) without cardiovascular disease and 30 healthy controls (24 males, 6 females; mean age 41.2±9.3 years; range, 32 to 50 years). We evaluated participants’ clinical, biological and functional status along with laboratory data and measured both the arterial stiffness using carotid-femoral pulse wave velocity (PWV) measured by applanation tonometry and carotid intima-media thickness (CIMT) as a preclinical atherosclerosis marker.

Results

The mean disease duration of AS patients was 10.6±4.2 years. CIMT (p=0.03) and PWV (p=0.04) data showed significant differences between AS patients and healthy controls. Multiregression analysis showed that PWV correlated with age (r²=0.42; p=0.03) and disease duration (r²=0.31; p=0.04), while CIMT correlated with disease duration (r²=0.37; p=0.03) and Bath Ankylosing Spondylitis Disease Activity Index (r²=0.3; p=0.04).

Conclusion

This study demonstrated an increase in early preclinical atherosclerosis in AS patients without cardiovascular (CV) disease compared to healthy controls. Therefore, screening AS patients with noninvasive methods for atherosclerosis and subclinical vasculopathy would allow us to take primary prevention measures. We found that the major determinant for increased CV risk was the disease duration, while there was no difference between different treatment modalities.

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.

Unexpected increase of aortic stiffness in juvenile Spondyloarthropathies

Juvenile spondyloarthropathy is an umbrella term for a group of childhood rheumatic diseases that can cause chronic arthritis extending to the axial skeleton before the age of 16. Although ankylosing spondylitis has aortic involvement as one of its most important effects, this relationship has not been extensively studied in children with juvenile spondyloarthropathy. Here, a cross-sectional study of the elastic properties of the aorta of 43 patients with juvenile spondyloarthropathy and 19 healthy controls is reported. Aortic stiffness assessed by echocardiography was used to predict the presence of aortitis, supplemented by pulsed-wave tissue Doppler indices. The right ventricular fractional area change was found to be significantly lower in the patients with juvenile spondyloarthropathy than in the healthy controls; aortic strain and distensibility were also significantly lower, and aortic stiffness index β was significantly higher; and the aortic root diameter change was significantly lower. According to HLA-B27 positivity, there was no difference in the stiffness parameters between the two groups. There was a significant correlation between juvenile Ankylosing Spondylitis Disease Activity Index and aortic diameter change, between juvenile Ankylosing Spondylitis Disease Activity Index and aortic stiffness. Thus, juvenile spondyloarthropathy is linked to high aortic stiffness parameters.

Cerebral hemodynamics in patients with ankylosing spondylitis

OBJECTIVE

The aim of this study was to assess the cerebral blood flow velocity as a marker by using transcranial Doppler (TCD) ultrasonography in patients with ankylosing spondylitis (AS).

METHODS

A total of 30 AS patients aged 20 to 50 were enrolled in the AS group (male/female: 4/26, mean age: 34.7 ± 5.9) consecutively. The control group (non-AS group; male/female: 4/26, mean age: 32.3 ± 4.7) consisted of 30 age- and sex-matched, randomly selected patients without AS who had other diagnoses such as fibromyalgia and did not have risk factors for atherosclerosis. Bilateral middle cerebral artery (MCA) peak-systolic, end-diastolic, and mean blood flow velocities, Gosling's pulsatility index values, and Pourcelot's resistance index values were recorded with TCD by a neurosonologist blinded to the AS and control groups.

RESULTS

The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels and cerebral blood flow velocities of bilateral MCA were significantly higher in the AS group than in the control group.

CONCLUSIONS

This study highlights that the increased cerebral blood flow is indirectly associated with atherosclerosis regarding persistent inflammation in patients with AS.

Cardiovascular morbidity and mortality in patients with spondyloarthritis: A meta-analysis

AIM

Cardiovascular (CV) risk and mortality associated with spondyloarthritis (SpA) remain controversial. Herein, we performed a meta-analysis of the latest large-scale population-based studies to demonstrate the elevated risk of CV disease and mortality in patients with SpA than in the general population.

METHODS

MEDLINE and EMBASE databases were searched systematically for population-based studies published between January 1997 and September 2019. Additional manual literature searches were also performed. All searches and data collection were performed independently by 2 reviewers. We calculated the risks of myocardial infarction (MI), stroke, and all-cause mortality in a meta-analysis and determined the risk ratios (RR) using the Mantel-Haenszel method.

RESULTS

Among the 641 identified articles, 16 articles involving 18 cases met the inclusion criteria for our meta-analysis; these included 12 cases of ankylosing spondylitis, five cases of psoriatic arthritis, and 1 case of undifferentiated SpA. Our meta-analysis revealed a significantly high risk of MI (RR: 1.52; 95% CI: 1.29-1.80) and stroke (RR: 1.21; 95% CI: 1.0-1.47) in patients with SpA than in the general population. However, this increased risk was not significant in terms of all-cause mortality (RR: 1.23; 95% CI: 0.96-1.57).

CONCLUSIONS

Our meta-analysis demonstrated that patients with SpA have a significantly increased risks of MI and stroke, but without a significant increase in the all-cause mortality, than that in the general population. The higher risk of CV in patients with SpA than that in the general population indicates the need for strict risk factor correction and disease management.

Does socioeconomic status make a difference? A register-based study on the extent to which cardiovascular screening in patients with inflammatory arthritis leads to recommended follow-up in general practice

OBJECTIVE

To investigate to what extent patients with inflammatory arthritis (IA) follow recommendations given in a secondary care nurse-led cardiovascular (CV) risk screening consultation to consult their general practitioner (GP) to reduce their CV risk and whether their socioeconomic status (SES) affects adherence.

METHODS

Adults with IA who had participated in a secondary care screening consultation from July 2012 to July 2015, based on the EULAR recommendations, were identified. Patients were considered to have high CV risk if they had risk Systematic COronary Risk Evaluation (SCORE) ≥5%, according to the European SCORE model or systolic blood pressure ≥145 mmHg, total cholesterol ≥8 mmol/L, LDL cholesterol ≥5 mmol/L, HbA1c ≥42 mmol/mol or fasting glucose ≥6 mmol/L. The primary outcome was a consultation with their GP and at least one action focusing on CV risk factors within 6 weeks after the screening consultation.

RESULTS

The study comprised 1265 patients, aged 18-85 years. Of these, 336/447 (75%) of the high-risk patients and 580/819 (71%) of the low-risk patients had a GP consultation. 127/336 (38%) of high-risk patients and 160/580 (28%) of low-risk patients received relevant actions related to their CV risk, for example, blood pressure home measurement or prescription for statins, antihypertensives or antidiabetics. Education ≥10 years increased the odds for non-adherence (OR 0.58, 95% CI 0.0.37 to 0.92, p=0.02).

CONCLUSIONS

75% of the high-risk patients consulted their GP after the secondary care CV risk screening, and 38% of these received an action relevant for their CV risk. Higher education decreased adherence.

Echocardiography in Autoimmune Rheumatic Diseases for Diagnosis and Prognosis of Cardiovascular Complications

Autoimmune rheumatic diseases are systemic diseases frequently affecting the heart and vessels. The main cardiovascular complications are pericarditis, myocarditis, valvular disease, obstructive coronary artery disease and coronary microcirculatory dysfunction, cardiac failure and pulmonary hypertension. Echocardiography, including transthoracic two and three-dimensional echocardiography, Doppler imaging, myocardial deformation and transesophageal echo, is an established and widely available imaging technique for the identification of cardiovascular manifestations that are crucial for prognosis in rheumatic diseases. Echocardiography is also important for monitoring the impact of drug treatment on cardiac function, coronary microcirculatory function, valvular function and pulmonary artery pressures. In this article we summarize established and evolving knowledge on the role of echocardiography for diagnosis and prognosis of cardiovascular abnormalities in rheumatic diseases.

Biomechanical Properties of Common Carotid Arteries Assessed by Circumferential 2D Strain and β Stiffness Index in Patients With Ankylosing Spondylitis

OBJECTIVE

Ankylosing spondylitis (AS) is associated with an elevated risk of cardiovascular disease (CVD) related to atherosclerosis, preceded by arterial stiffness. We aimed to examine common carotid artery (CCA) biomechanical properties using ultrasound to calculate β stiffness index (indicating arterial stiffness) and, a more recently developed technique, 2-dimensional (2D) speckle tracking strain (indicating arterial motion and deformation, strain) to (1) compare with age- and sex-matched controls, and (2) analyze relationships between strain and stiffness with disease characteristics and traditional risk factors for CVD in patients with AS.

METHODS

In this cross-sectional study, a cohort of 149 patients with AS, mean age 55.3 ± 11.2 years, 102 (68.5%) men, and 146 (98%) HLA-B27-positive, were examined. Bilateral CCA were examined for circumferential 2D strain and β stiffness index. A subgroup of 46 patients was compared with 46 age- and sex-matched controls, both groups without hypertensive disease, diabetes, myocardial infarction, or stroke.

RESULTS

Mean bilateral circumferential 2D strain was lower in AS patients compared with controls (7.9 ± 2.6% vs 10.3 ± 1.9%, P < 0.001), whereas mean bilateral β stiffness index was higher (13.1 ± 1.7 mmHg/mm vs 12.3 ± 1.3 mmHg/mm, P = 0.02). In multivariable linear regression analyses, strain was associated with age, erythrocyte sedimentation rate, history of anterior uveitis, and treatment with conventional synthetic disease-modifying antirheumatic drugs (DMARD) and/or biological DMARD (R² 0.33), while stiffness was associated with age (R² 0.19).

CONCLUSION

Both CCA circumferential 2D strain and β stiffness index differed between patients with AS and controls. Strain was associated with AS-related factors and age, whereas only age was associated with stiffness, suggesting that the obtained results reflect different pathogenic vascular processes.

Pharmacological management of cardiovascular risk in chronic inflammatory rheumatic diseases

INTRODUCTION

Cardiovascular comorbidity is a major burden in patients with chronic inflammatory rheumatic diseases and a significant determinant of their outcome. In addition to optimal management of the underlying inflammatory condition according to current guidelines, individual cardiovascular risk factors, particularly dyslipidaemia, hypertension, and impaired glucose tolerance should be assessed regularly and guide risk stratification and requirement for treatment.

AREAS DISCUSSED

We critically reviewed manuscripts and guidelines on the pharmacological management of dyslipidaemia, hypertension, and diabetes in patients with chronic inflammatory rheumatic diseases (PubMed, MEDLINE, EMBASE, Scopus, Web of Science and Google Scholar, up to 1 March 2020). Lifestyle changes are of paramount importance for the management of these risk factors. In the current narrative review, we discuss pharmacological therapies available and emerging therapies aiming to help patients achieve recommended targets, depending on their individual risk.

EXPERT OPINION

CVD risk is increased in people with chronic inflammatory rheumatic diseases. Cardiovascular risk factor management is an essential part of their care. Although relevant guidance exists, there are still major gaps in knowledge and risk factor management implementation in these patient groups. Some practical guidance based on our interpretation of existing data and experience in the field is provided in this review.

Link Between Synovial and Myocardial Inflammation: Conceptual Framework to Explain the Pathogenesis of Heart Failure with Preserved Ejection Fraction in Patients with Systemic Rheumatic Diseases

Patients with a broad range of systemic rheumatic diseases are at increased risk of heart failure (HF), an event that is not related to traditional cardiovascular risk factors or underlying ischaemic heart disease. The magnitude of risk is linked to the severity of arthritic activity, and HF is typically accompanied by a preserved ejection fraction. Subclinical evidence for myocardial fibrosis, microcirculatory dysfunction and elevated cardiac filling pressures is present in a large proportion of patients with rheumatic diseases, particularly those with meaningful systemic inflammation. Drugs that act to attenuate pro-inflammatory pathways (methotrexate and antagonists of tumour necrosis factor and interleukin-1) may ameliorate myocardial inflammation and cardiac structural abnormalities and reduce the risk of HF events.

Evidence for Inflammation as a Driver of Atrial Fibrillation

Atrial fibrillation (AF) is one of the most common types of arrhythmias and increases cardiovascular morbidity and mortality. Current therapeutic approaches to AF that focus on rhythm control have high recurrence rates and no life prolongation value. While possible explanations include toxicity of current therapies, another likely explanation may be that current therapies do not address fundamental mechanisms of AF initiation and maintenance. Inflammation has been shown to affect signaling pathways that lead to the development of AF. This paper reviews the roles of inflammation in the occurrence, development, and mechanisms of AF and reviews the therapeutic implications of the correlation of inflammation and AF.

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.

Cardiac conduction disturbances in patients with ankylosing spondylitis: results from a 5-year follow-up cohort study

Objectives

To describe electrocardiographic (ECG) development in patients with ankylosing spondylitis (AS) and identify associations between baseline characteristics and cardiac conduction disturbances (CCD) at 5-year follow-up.

Methods

In a longitudinal cohort study, 172 patients (54% men, mean age (SD) of 50 (13) years at baseline) with AS underwent ECG, physical examination, questionnaires and laboratory testing at baseline and at 5-year follow-up. Descriptive statistics and univariate and age- and sex-adjusted logistic regression analyses were used. CCD included both atrioventricular and intraventricular blocks.

Results

Twenty-three of the 172 patients (13.4%) had a CCD at follow-up. Eight patients had developed a new CCD and eight had normalised their ECG. In the age- and sex-adjusted analyses, CCD at baseline (OR 24.8, 95% CI 7.3 to 84.5), male sex (OR 6.4, 95% CI 2.0 to 20.8), history of anterior uveitis (OR 4.4, 95% CI 1.3 to 14.5), higher ASDAS-CRP (OR 2.3, 95% CI 1.3 to 4.0), greater waist circumference (OR 1.3, 95% CI 1.1 to 1.6, per 5 cm), and medication with antiplatelets (OR 7.0, 95% CI 1.5 to 31.8) and beta-blockers (OR 3.4, 95% CI 1.0 to 11.5) were associated with a CCD at follow-up. Higher age and longer symptom duration were highly correlated and were both associated with a CCD at follow-up.

Conclusions

The presence of CCD in AS is in part dynamic and associated with both AS and non-AS characteristics. Our results suggest that patients especially prone to present with CCDs are older men with a previous CCD, longer symptom duration, higher AS disease activity, a history of anterior uveitis and medication reflecting cardiovascular disease.

Lifetime Risks of Valvular Heart Disease and Pacemaker Use in Patients With Ankylosing Spondylitis

Background The likelihoods of valvular heart disease ( VHD ) and conduction abnormalities in patients with ankylosing spondylitis ( AS p) are poorly defined. Knowing their lifetime risks of VHD and pacemaker use would help inform whether cardiac screening should be done. Methods and Results Patients with AS p and a comparison group without AS p were identified among US Medicare beneficiaries in 1999 to 2013. Frequencies of VHD and pacemaker use were compared in 4 age groups: 65 to 69 years, 70 to 74 years, 75 to 79 years, and 80 years or older, as were rates of valve surgeries, a measure of VHD severity, and new pacemaker insertions. Outcomes were compared between 42 327 patients with AS p and 19 211 703 patients without AS p. The prevalence of aortic valve disease in patients with AS p increased with age (2.6%, 6.7%, 10.9%, and 17.1%), as did the prevalence of mitral valve disease. Risks of VHD were slightly but significantly higher in patients with AS p (adjusted odds ratios 1.06-1.51). Rates of aortic valve replacement/repair were also higher in patients with AS p than in the comparison group (125 versus 93; 183 versus 149; 261 versus 208; 279 versus 191 per 100 000 patient-years in the 4 age groups). Rates of mitral valve surgery did not differ between groups. Among patients with AS p, pacemaker use ranged from 1.0% to 7.6% across age groups, and was slightly higher than in controls (odds ratio range 1.11-1.32). Conclusions Lifetime risks of VHD and pacemaker use in AS p increase markedly with age, but are only slightly higher than in elderly people without AS p.

TPM2 as a potential predictive biomarker for atherosclerosis

Cardiac-cerebral vascular disease (CCVD), is primarily induced by atherosclerosis, and is a leading cause of mortality. Numerous studies have investigated and attempted to clarify the molecular mechanisms of atherosclerosis; however, its pathogenesis has yet to be completely elucidated. Two expression profiling datasets, GSE43292 and GSE57691, were obtained from the Gene Expression Omnibus (GEO) database. The present study then identified the differentially expressed genes (DEGs), and functional annotation of the DEGs was performed. Finally, an atherosclerosis animal model and neural network prediction model was constructed to verify the relationship between hub gene and atherosclerosis. The results identified a total of 234 DEGs between the normal and atherosclerosis samples. The DEGs were mainly enriched in actin filament, actin binding, smooth muscle cells, and cytokine-cytokine receptor interactions. A total of 13 genes were identified as hub genes. Following verification of animal model, the common DEG, Tropomyosin 2 (TPM2), was found, which were displayed at lower levels in the atherosclerosis models and samples. In summary, DEGs identified in the present study may assist clinicians in understanding the pathogenesis governing the occurrence and development of atherosclerosis, and TPM2 exhibits potential as a promising diagnostic and therapeutic biomarker for atherosclerosis.

Thoracic Manifestations of Ankylosing Spondylitis, Inflammatory Bowel Disease, and Relapsing Polychondritis

Ankylosing spondylitis, inflammatory bowel disease (IBD), and relapsing polychondritis are immune-mediated inflammatory diseases with variable involvement of lungs, heart and the chest wall. Ankylosing spondylitis is associated with anterior chest wall pain, restrictive lung disease, obstructive sleep apnea, apical fibrosis, spontaneous pneumothorax, abnormalities of cardiac valves and conduction system, and aortitis. Patients with IBD can develop necrobiotic lung nodules that can be misdiagnosed as malignancy or infection. Relapsing polychondritis involves large airways in at least half of the patients. Relapsing polychondritis can mimic asthma in some patients. Medications used to treat these inflammatory conditions can cause pulmonary complications such as infections, pneumonitis, and rarely serositis.

Heart Involvement in Inflammatory Rheumatic Diseases: A Systematic Literature Review

Introduction: Patients with inflammatory rheumatic diseases have an increased risk of developing cardiovascular manifestations. The high risk of cardiovascular pathology in these patients is not only due to traditional cardiovascular risk factors (age, gender, family history, smoking, sedentary lifestyle, cholesterol), but also to chronic inflammation and autoimmunity. Aim: In this review, we present the mechanisms of cardiovascular comorbidities associated with inflammatory rheumatic diseases, as they have recently been reported by different authors, grouped in electrical abnormalities, valvular, myocardial and pericardial modifications and vascular involvement. Methods: We conducted a systematic search of published literature on the following online databases: EBSCO, ScienceDirect, Scopus and PubMed. Searches were limited to full-text English-language journal articles published between 2010 and 2017 using the following key words: heart, systemic inflammation, autoimmunity, rheumatic diseases and disease activity. After the primary analysis we included 50 scientific articles in this review. Results: The results showed that cardiac manifestations of systemic inflammation can occur frequently with different prevalence in rheumatoid arthritis (RA), systemic lupus erythematosus(SLE), systemic sclerosis(SSc) and ankylosing spondylitis(AS). Rheumatologic diseases can affect the myocardium, cardiac valves, pericardium, conduction system and arterial vasculature. Conclusions: Early detection, adequate management and therapy of specific cardiac involvement are essential in rheumatic disease. Electrocardiographic and echocardiographic evaluation should be performed as routine investigations in patients with inflammatory rheumatic diseases.

Cardiovascular safety of non-steroidal anti-inflammatory drugs in chronic inflammatory rheumatic diseases

Rheumatic diseases (RD), such as rheumatoid arthritis, systemic lupus erythematosus, ankylosing spondylitis, psoriatic arthritis, vasculitis, gout are associated with increase in cardiovascular morbidity and mortality. The main causes of increased cardiovascular risk are inflammatory heart and vascular lesions, accelerated progression of atherosclerosis and side effects of drug therapy. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in clinical practice and are on the list of the most prescribed medications. It is known that NSAIDs have a negative effect on the cardiovascular system (CVS). However NSAIDs may decrease the intensity of inflammation, which is an independent risk risk factor for CVS pathology. Therefore in patients with RD it is theoretically possible to reduce the severity of cardiovascular side effects when using NSAIDs. The article discusses the issues of NSAID's cardiovascular safety, the molecular mechanisms underlying the negative effect of them on CVS, critically evaluated the results of main studies concerning the cardiovascular safety of NSAIDs in chronic inflammatory diseases.

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.

Evaluation of subclinical atherosclerosis using ultrasound radiofrequency data technology in patients diagnosed with ankylosing spondylitis

OBJECTIVE

The present study aims to identify the cardiovascular risk associated with chronic inflammation and disease activity in patients with ankylosing spondylitis (AS) using noninvasive ultrasonographic radiofrequency data technology.

METHODS

In this study, a total of 87 participants, 38 patients with AS and 49 healthy controls, were evaluated by Doppler ultrasonography. Intima-media thickness (IMT) and arterial stiffness were measured from the bilateral common carotid artery using the radiofrequency method.

RESULTS

No statistically significant difference was found between the AS patients and healthy controls concerning the right common carotid artery, left common carotid artery, IMT, distensibility coefficient, elasticity coefficient, α and β stiffness indexes, and pulse wave velocities (P > .05). The symptom duration of the AS patients had a positive correlation that was moderate and was detected with the α stiffness index and pulse wave velocity (P < .05). The duration of diagnosis and treatment of the AS patients had a positive correlation that was moderate, was detected with the α stiffness index, the β stiffness index, and pulse wave velocity (P < .05). The mean IMT and elasticity coefficient values of the AS patients whose Bath Ankylosing Spondylitis Disease Activity Index score was 4 and above, were substantially higher than the values in the patients with scores lower than 4 (P = .038 and P = .33, respectively).

CONCLUSIONS

Subclinical atherosclerosis is not accelerated in AS patients with low disease activity, although insufficiently controlled disease activity may result in increased carotid IMT and atheromatosis. Radiofrequency data technology provides a noninvasive method for accurately and quantitatively demonstrating CCA-IMT elevation and the decrease in vascular elasticity in patients with AS.

Association of Congestive Heart Failure and Death with Ankylosing Spondylitis : A Nationwide Longitudinal Cohort Study in Korea

Objective

We attempted to discover that Ankylosing spondylitis (AS) has a comprehensive relationship with congestive heart failure and death.

Methods

We used a nationwide database managed by the Korean National Health Insurance Service from 2010 to 2014. Twelve thousand nine hundred eighty-eight patients with a diagnosis of AS and 64940 age- and sex- stratified matching subjects without AS were enrolled in the AS and control groups. Incidence probabilities of 6 years congestive heart failure and death in each group were calculated. The Cox proportional hazard regression analysis was used to estimate the hazard ratio. We divided the AS and control groups into subgroups according to sex, age, income, and comorbidities.

Results

During the follow-up period, 102 patients (0.79%) in the AS group and 201 patients (0.32%) in the control group developed congestive heart failure (p<0.0001). In addition, 211 (1.62%) subjects in the AS group died during the follow-up period compared to 639 (0.98%) subjects in the control group (p<0.0001). The adjusted hazard ratio of congestive heart failure and death in the AS group was 2.28 (95% confidence interval [CI], 1.80–2.89) and 1.66 (95% CI, 1.42–1.95), respectively. The hazard ratios of congestive heart failure and death were significantly increased in all of the subgroups.

Conclusion

The incidence rates of congestive heart failure and death were increased in AS patients.

Risk of venous thromboembolism in ankylosing spondylitis: a general population-based study

Background

Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep venous thrombosis (DVT), can be life threatening. An increased frequency of VTE has been found in inflammatory conditions. To date, evidence assessing whether this risk is also greater in patients with ankylosing spondylitis (AS) is scarce.

Methods

Using the provincial British Columbia, Canada healthcare database that encompasses all residents within the province, we conducted matched cohort analyses of incident PE, DVT and overall VTE among incident cases of AS and compared them with individuals randomly selected from the general population without AS. We calculated incidence rates (IRs) of VTE and multivariable analyses after adjusting for traditional risk factors using Cox models.

Results

Among 7190 incident cases of AS, 35 developed PE and 47 developed DVT. IRs of PE, DVT and overall VTE per 1000 person-years for patients with AS were 0.79, 1.06, 1.56 compared with 0.40, 0.50, 0.77 in the control cohort. Corresponding fully adjusted HRs (95% CI) of PE, DVT and VTE were 1.36 (0.92 to 1.99), 1.62 (1.16 to 2.26) and 1.53 (1.16 to 2.01), respectively. The risks of PE, DVT and VTE were highest in the first year of diagnosis with HR (95% CI) of 2.88 (0.87 to 9.62), 2.20 (0.80 to 6.03) and 2.10 (0.88 to 4.99), respectively.

Conclusions

These findings demonstrate an increased risk of VTE in the general AS population. This risk appears the most prominent in the first year after diagnosis.

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.
