FRI0308 ANKYLOSING SPONDYLITIS PATIENTS AT RISK OF DEVELOPING AORTIC VALVE REGURGITATION, NEED FOR MANDATORY ECHOCARDIOGRAPHY?

Background:

The overall mortality rate in ankylosing spondylitis (AS) patients is increased by 60–90% compared with the general population. This higher mortality rate is predominately caused by cardiovascular disease (CVD) comprising an increased prevalence of cardiac diseases such as valvular heart disease, conduction disturbances and cardiomyopathies as well as atherosclerotic diseases such as myocardial infarctions. However, there is a lack of contemporary studies. Therefore, we investigated current prevalences of cardiac disorders in a well characterized cohort of Dutch patients with AS compared to osteoarthritis (OA) controls.

Objectives:

To assess the prevalence of CVD in AS patients in comparison to OA controls in a Dutch population.

Methods:

We performed a cross-sectional study in AS and OA patients between 50-75 years. Subjects were recruited from a large rheumatology outpatient clinic (Reade) in Amsterdam, the Netherlands. Patients underwent echocardiography with 2D, spectral and Color Doppler imaging. The echocardiogram was evaluated by an experienced and certified cardiologist. Diastolic dysfunction was assessed according to the ASE/EACVI 2016 guideline. Furthermore, blood sample, surveys and physical examination were done. Disease activity and function were measured with the BASFI, BASDAI and the ASDAS-CRP.

Results:

A total of 193 consecutive AS patients were included with a median age of 60 (±7) years of which 72% men (138). The control group consisted of 70 OA patients (table 1). In the AS cohort the disease activity measures, BASDAI, ASDAS-CRP and BASFI, indicated moderate disease activity and were, respectively 3.1 (1.6-5.0), 2.1 (±1.0) and 3.5 (1.7-5.7). Anti-TNF was used by 43% of the AS patients. History of cardiovascular disease (CVD), i.e. angina pectoris, myocardial infarction, stroke and/or peripheral ischemia was comparable between the AS and OA cohort, respectively 9% (17) and 10% (7), p=0.81. Antihypertensives were significantly more often used in AS patients, 85 (44%) vs 19 (27%), p=0.02. Prevalences of systolic dysfunction and diastolic dysfunction did not differ significantly in AS and OA patients, respectively 6 (5%) vs 2 (5%), p=0.96 in systolic dysfunction and 7 (3%) vs 2 (3%), p=0.86 in diastolic dysfunction. Prevalence of aortic valve (AV) regurgitation was significantly higher in AS patients compared to OA patients, respectively 41 (22%) and 7 (10%), mostly with mild severity. The prevalence of mitral valve (MV) regurgitation did not differ between the AS and OA patients, respectively 68 (36%) vs 21 (33%), p=0.59. When corrected for age, gender and cardiovascular risk factors in a regression analysis, AS patients still had a substantially increased risk for AV regurgitation, odds ratio (OR) 2.8 95%CI 1.1-7.2, p=0.038.

Conclusion:

This study demonstrates an almost tripled risk for developing AV regurgitation in Dutch AS patients. Although mostly mild in this age, due to the progressive nature of AV regurgitation in AS, echocardiographic screening should be considered in elderly AS patients.

The effects of golimumab treatment on systolic and diastolic left ventricular function in ankylosing spondylitis

Background

Diastolic left ventricular (LV) dysfunction appears more prevalent in ankylosing spondylitis (AS). The effects of tumor necrosis factor alpha (TNF-α) blocking therapy, a strong and effective anti-inflammatory drug, on diastolic LV function in AS are unknown. The objective of the study was to find the effects of 1-year treatment with golimumab 50 mg subcutaneously once per month on systolic and diastolic LV dysfunction in AS patients.

Methods

Forty consecutive AS patients were treated with TNF-α blocking therapy for 1 year. Transthoracic echocardiography was performed in all patients at baseline and after 1 year of treatment.

Results

Diastolic LV function improved after treatment in four out of six (67%) AS patients who completed follow-up (P=0.125), and did not develop or worsen in any of the other patients. Treatment with TNF-α blocking therapy had no effect on systolic LV function.

Conclusion

These findings give support to the hypothesis that diastolic LV dysfunction improves during treatment with TNF-α blocking therapy.

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.

Atherosclerotic cardiovascular disease in patients with chronic inflammatory joint disorders

Inflammatory joint disorders (IJD), including rheumatoid arthritis (RA), ankylosing spondylitis (ASp) and psoriatic arthritis (PsA), are prevalent conditions worldwide with a considerable burden on healthcare systems. IJD are associated with increased cardiovascular (CV) disease-related morbidity and mortality. In this review, we present an overview of the literature. Standardised mortality ratios are increased in IJD compared with the general population, that is, RA 1.3-2.3, ASp 1.6-1.9 and PsA 0.8-1.6. This premature mortality is mainly caused by atherosclerotic events. In RA, this CV risk is comparable to that in type 2 diabetes. Traditional CV risk factors are more often present and partially a consequence of changes in physical function related to the underlying IJD. Also, chronic systemic inflammation itself is an independent CV risk factor. Optimal control of disease activity with conventional synthetic, targeted synthetic and biological disease-modifying antirheumatic drugs decreases this excess risk. High-grade inflammation as well as anti-inflammatory treatment alter traditional CV risk factors, such as lipids. In view of the above-mentioned CV burden in patients with IJD, CV risk management is necessary. Presently, this CV risk management is still lacking in usual care. Patients, general practitioners, cardiologists, internists and rheumatologists need to be aware of the substantially increased CV risk in IJD and should make a combined effort to timely initiate CV risk management in accordance with prevailing guidelines together with optimal control of rheumatic disease activity. CV screening and treatment strategies need to be implemented in usual care.
