Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory arthritis affecting the spine, presenting a considerable morbidity risk. Although evidence consistently indicates an elevated risk of ischemic heart disease among AS patients, debates persist regarding the likelihood of these patients developing left ventricular dysfunction (LVD). Our investigation aimed to determine whether individuals with AS face a greater risk of LVD compared to the general population. To accomplish this, we identified studies exploring LVD in AS patients across five major databases and Google Scholar. Initially, 431 studies were identified, of which 30 met the inclusion criteria, collectively involving 2933 participants. Results show that AS patients had: (1) poorer Ejection Fraction (EF) [mean difference (MD): -0.92% (95% CI: -1.25 to -0.59)], (2) impaired Early (E) and Late (atrial-A) ventricular filling velocity (E/A) ratio [MD: -0.10 m/s (95% CI: -0.13 to -0.08)], (3) prolonged deceleration time (DT) [MD: 12.30 ms (95% CI: 9.23-15.36)] and, (4) a longer mean isovolumetric relaxation time (IVRT) [MD: 8.14 ms (95% CI: 6.58-9.70)] compared to controls. Though AS patients show increased risks of both systolic and diastolic LVD, we found no significant differences were observed in systolic blood pressure [MD: 0.32 mmHg (95% Confidence Interval (CI): -2.09 to 2.73)] or diastolic blood pressure [MD: 0.30 mmHg (95% CI: -0.40 to 1.01)] compared to the general population. This study reinforces AS patients' susceptibility to LVD without a notable difference in HTN risk.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To clarify if musculoskeletal ultrasound (US) would give additional information for the clinical examination to diagnose and evaluate the activity of ankylosing spondylitis (AS). METHODS A literature search was performed in PubMed, Embase, Web of Science, the Cochrane Library, Sinomed, Chinese National Knowledge Infrastructure (CINK), and Wanfang databases from their inceptions to May 15, 2020. Studies that examined the musculoskeletal US, which detected sacroiliac joints in people with AS were included. The pooled analyses were performed using Meta Disc version 1.4 software. RESULTS A total of 9 studies encompassing 984 participants were included. Statistical analysis suggested an area under the curve (AUC) of 0.9259 (sensitivity 0.86, specificity 0.54) indicating that US had excellent diagnostic test accuracy for AS, an AUC of 0.6441 (sensitivity 0.87, specificity 0.51) indicating that the US did not have a good diagnostic test accuracy for AS activity. A subgroup analysis revealed that the AUC of power Doppler US (PDUS) and color Doppler US (CDUS) was 0.5000 and 0.9274, respectively, indicating that CDUS was superior to PDUS. CONCLUSION US, especially CDUS, is a valid and reproducible technique for the diagnosis of AS. While the accuracy of AS activity evaluation of the US is not ideal. It may be considered for routine use as part of the standard diagnostic tools in AS.

Abstract
Juvenile idiopathic arthritis (JIA) is the commonest rheumatic disease in childhood and presents several subtypes according to the ILAR classification. JIA, specifically in its systemic form, may seriously damage various structures of the cardiovascular system. Other JIA phenotypes are also of interest, as cardiovascular disease (CVD) is underestimated and understudied, but chronic systemic inflammation and risk factors remained important contributors for CVD development. The currently applied non-invasive modalities, although they are important for the initial evaluation of JIA patients, frequently fail to detect the silent, subclinical forms of CVD. Cardiovascular magnetic resonance (CMR), due to its multifaceted capability in the detection of cardiovascular disease, can offer early, reproducible, non-invasive information about cardiovascular disease in JIA, allowing risk stratification and timely initiation /modification of cardiologic and anti-rheumatic treatment. However, lack of availability/expertise and high cost still hamper its application in the clinical cardio-rheumatic practice. The aim of the current article is to present an overview of CVD in JIA emphasizing the emerging role of CMR in early diagnosis and treatment follow-up of CVD in JIA patients.

Abstract
Ankylosing spondylitis (AS) is a chronic inflammatory disease which is characterized by the primary involvement of axial spine and sacroiliac joints and also extraarticular involvements including ophthalmological, cardiac, pulmonary, or neurological effects. Cardiac involvement in patients with AS has been reported to be 2 to 10%. Ventricular dysfunctions have been previously reported in patients with AS. However, there is only one case report describing primary cardiomyopathy due to AS and management with better control of inflammation and medications. Herein, we present a case of cardiomyopathy in AS in whom ejection fraction and New York Heart Association (NYHA) functional class improved and disease activity decreased after cardiac rehabilitation program.

Abstract
Juvenile arthritis damage index (JADI) consists of two parts which measure articular (JADI-A) and extra-articular (JADI-E) damage in patients with juvenile idiopathic arthritis (JIA). It does not include assessment of cardiac dysfunction and joint areas commonly affected in enthesitis-related arthritis (ERA) category of JIA. We have tried to study if modification of JADI will improve its performance in JIA-ERA. We studied 101 consecutive patients of JIA-ERA. JADI-A was modified (JADI-AM) to include damage assessment of tarsal joints and lumbar spine. JADI-E was modified (JADI-EM) to include assessment of symptomatic cardiac dysfunction. The performances of the modified and standard JADI were compared. Ninety-seven patients were male. The median age was 18 years (9-36). At a median disease duration of 6 years (1-24), joint damage was observed in 47 as assessed by JADI-A. JADI-AM could identify 11 more patients (N = 58) with articular damage. JADI-AM had good correlation with number of joints with limitation of movement (Spearman's [rS] = 0.9) and low to moderate correlation (rS < 0.7) with measures of disease activity and functional status. JADI-AM discriminated well among patients with different disability levels. Extra-articular damage was observed in 35, and modification of JADI-E with inclusion of cardiac dysfunction did not identify any additional patient. Thus, we propose a modification of the JADI-A (JADI-AM). In JIA-ERA, modification of JADI-A improves its ability to identify articular damage. Modification of the JADI-E may not be needed as symptomatic cardiac involvement is rare.

Abstract
OBJECTIVE To measure aortic stiffness and global left ventricular (LV) function in patients with ankylosing spondylitis (AS) and no clinical evidence of heart disease. METHODS Fifty-seven consecutive patients with AS (54 males, three females, mean age 41.78+/-10.02 years) without clinical evidence of cardiac involvement and 78 healthy subjects (73 males, five females, mean age 39.92+/-9.11 years) underwent complete echocardiographic study. Aortic stiffness was determined non-invasively by aortic distensibility (AoD) and the global LV function was evaluated by the myocardial performance index (the Tei index). RESULTS AoD in patients with AS [(2.21+/-0.24)x10(-6) cm(2) dyn(-1)] was decreased compared to controls [(2.58+/-0.19) )x10(-6) cm(2) dyn(-1), p<0.01], confirming that aortic stiffness is increased in AS. The LV Tei index was significantly increased in the patient group compared to the control group (0.392+/-0.031 vs. 0.370+/-0.034, p<0.01). The ejection fraction (EF) did not differ between the two groups (p>0.05). In multivariate linear regression analysis, AoD was significantly associated with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and LV isovolumic relaxation time (IVRT) whereas the LV Tei index was associated with BASDAI and the LV mass index. CONCLUSIONS Patients with AS and no clinical evidence of cardiac disease have increased stiffness of the aorta and decreased global myocardial performance and both of these abnormal measurements correlate with disease activity. The abnormal Tei index may reflect an early manifestation of cardiac dysfunction in these patients.

Abstract
Juvenile spondylarthropathies (JSpAs) comprise a group of rheumatic diseases distinct from other categories of juvenile arthritis. Several classification systems have been applied, and some are specific for children, such as the seronegative enthesopathy and arthropathy (SEA) syndrome and the enthesitis-related arthritis, diagnostic forms in the International League of Associations for Rheumatism (ILAR) classification. JSpA seems more frequent than was previously believed, but actual epidemiological data show important variations between studies. Compared to adult patients, children with JSpA present with peripheral arthritis and enthesitis early in disease but sacroiliac and spine joints involvement many years later. A multidisciplinary team in a paediatric environment should be responsible for the management of children with spondylarthropathies to ensure the best care for these children with their chronic disease and risk of long-term disability. Recent advances in the treatment of rheumatic diseases with biological agents show promising results in children with JSpA. Further research needs to be conducted to increase our knowledge of the long-term outcome of these patients, to improve management, and to prevent long-term consequences of the disease.

Abstract
Aortic valve lesions are often found in patients with rheumatic diseases, but their clinical significance has not been properly evaluated. In the present study, the echocardiographic files of the cardiology unit of the Oulu University Hospital were screened for a diagnosis of aortic insufficiency (AI). The aetiology of the valve disease and specific details of the rheumatic disease were evaluated in 160 patients. Twenty-eight patients (18%) had a history of rheumatic fever. Rheumatic disease was found in 14 patients (8.8%) with AI, which is significantly more than the prevalence of rheumatic diseases (1.8%) in the corresponding age group (35-100 years) in Finland. Rheumatoid arthritis or juvenile rheumatoid arthritis was found in seven patients (4.4%), whereas ankylosing spondylitis or seronegative spondylarthropathy were found in four patients (2.5%). Other rheumatic diseases included Takayasu's arteritis (two patients) and scleroderma (one patient). When 38 patients with pure AI without other possible aetiology were analysed, rheumatic disease was found in five patients (13%). Patients with rheumatic disease as a potential aetiology of AI often had symptomatic valve disease, which required surgical treatment, although great differences between different aetiologies were not found.

Abstract
This article reviews recent publications related to the classification and treatment of juvenile spondyloarthropathies. We have included studies on adult onset spondyloarthropathies that are particularly relevant to childhood onset disease. Significant questions concerning classification of juvenile spondyloarthropathies remain unresolved. Diagnostic criteria that are both sensitive and specific for identifying undifferentiated spondyloarthropathies in adults have been developed, and while separate criteria have been proposed for juvenile onset disease, they remain to be validated. The most significant recent advances have occurred in the area of treatment. A small number of studies suggest that bisphosphonates such as pamidronate may be efficacious. Several studies using the TNF inhibitors infliximab and etanercept suggest that these agents hold great promise for ameliorating symptoms and improving function, while long-term effects on disease progression remain to be evaluated.

Abstract
The juvenile-onset spondyloarthritides comprise a group of HLA-B27-associated disorders, which are mainly characterized by enthesitis and arthritis affecting the lower extremities, and in a variable proportion of cases, the sacroiliac and spinal joints. Additional features include a variety of extra-articular manifestations, and in some cases, bacterial infections as triggers. Except for the prevalence of some clinical features at onset and severity throughout the course of the disease, juvenile-onset SpA resemble their adult counterpart in most clinical aspects, strength of HLA-B27 association, and the role of arthritogenic bacteria in their pathogenesis. Not surprisingly, several aspects, from nomenclature to classification, and diagnostic criteria reflect to some extent those developed in the adult onset populations.
