Cardiac Arrhythmias and Conduction Disturbances in Patients With Ankylosing Spondylitis

Conduction disturbances, aortic incompetence, and myocardial fibrosis are known complications in adult patients with ankylosing spondylitis (AS). Its incidence has been reported to be 10% to 30%; however, less attention has been paid to all cardiac arrhythmias. The aim of this study was to evaluate arrhythmias and conduction disturbances in patients with AS using electrocardiograms and Holter monitoring (including heart rate variability analysis) and to estimate its relationships with age, gender, clinical features, and duration of AS. Thirty-one patients with AS (20 to 69 years old, mean 50 ± 14) and 22 healthy volunteers (26 to 69 years old, mean 49 ± 13) underwent rheumatologic and cardiologic evaluations. Ventricular extrasystoles were present in 55% of AS patients and in 28% of controls. Supraventricular extrasystoles were present in 94% of AS patients and 100% of controls. The frequency of ventricular extrasystoles was found to be higher in the AS patients than in the control subjects. Significant differences were found in heart rate variability analyses: ultra low-frequency power and root mean square recessive difference (r-MSSD) were lower in the AS group. When the AS group was divided into subgroups (stages 3 and 4), significant differences were found between control subjects and stage 3 patients in PR interval, heart rate (HR), T-wave duration, ultra low frequency, and r-MSSD and between controls and stage 4 patients in HR, T-wave duration, and r-MSSD. QTc and QTd were not significantly different in groups and subgroups and were not correlated with any other clinical or electrocardiographic parameter. Cardiac arrhythmias were more frequent in patients with AS than in the healthy population. Simple electrocardiograms and Holter parameters do not correlate with the incidence of VESs, age, gender, clinical features, and duration of AS.

Serum IL-6 and IL-23 Levels and Their Correlation with Angiogenic Cytokines and Disease Activity in Ankylosing Spondylitis, Psoriatic Arthritis, and SAPHO Syndrome

Objectives. To assess serum interleukin-6 (IL-6) and interleukin-23 (IL-23) and their correlation with angiogenic cytokines and disease activity in ankylosing spondylitis (AS), psoriatic arthritis (PsA), and SAPHO syndrome. Patients and Methods. We studied 152 spondyloarthritis (SpA) patients: 69 PsA, 61 AS, 22 SAPHO, and 29 controls. We recorded age, sex, disease duration, and treatment. We assessed BASDAI, VAS, and PASI scores. Serum IL-6, IL-23, VEGF, EGF, FGFb, and FGFa levels were determined using ELISA. We estimated ESR and CRP. Results. Serum IL-6 and IL-23 levels were higher in SpA than in control (P < 0.00001 and P = 0.0004, resp.). There was a positive correlation between serum IL-6 and CRP in AS (P = 0.000001), PsA (P = 0.000001), and SAPHO (P = 0.0003) patients. There was a positive correlation between serum IL-6 and ESR in AS (P = 0.000001), PsA (P = 0.002), and SAPHO (P = 0.02) patients. There was no correlation of serum IL-6 and IL-23 with VAS, BASDAI, and angiogenic cytokines in SpA. Conclusions. Serum IL-6 but not serum IL-23 correlated with ESR and CRP in SpA. No correlation was found of serum IL-6 and IL-23 with VAS, BASDAI, and angiogenic cytokines.

Serum Interleukin-18, Fetuin-A, Soluble Intercellular Adhesion Molecule-1, and Endothelin-1 in Ankylosing Spondylitis, Psoriatic Arthritis, and SAPHO Syndrome

To examine serum interleukin 18 (IL-18), fetuin-A, soluble intercellular adhesion molecule-1 (sICAM-1), and endothelin-1 (ET-1) levels in ankylosing spondylitis (AS), psoriatic arthritis (PsA), and Synovitis Acne Pustulosis Hyperostosis Osteitis syndrome (SAPHO). We studied 81 AS, 76 PsA, and 34 SAPHO patients. We measured serum IL-18, fetuin-A, sICAM-1, ET-1, IL-6, IL-23, vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF). IL-18 levels were higher in AS (p = 0.001), PsA (p = 0.0003), and SAPHO (p = 0.01) than in controls, and were positively correlated with CRP (p = 0.03), VEGF (p = 0.03), and total cholesterol (TC, p = 0.006) in AS and with IL-6 (p = 0.03) in PsA. Serum fetuin-A levels were lower in AS (p = 0.001) and PsA (p = 0.001) than in controls, and negatively correlated with C-reactive protein (CRP) in AS (p = 0.04) and SAPHO (p = 0.03). sICAM-1 positively correlated with CRP (p = 0.01), erythrocyte sedimentation rate (ESR, p = 0.01), and IL-6 (p = 0.008) in AS, and with IL-6 (p = 0.001) in SAPHO. Serum ET-1 levels were lower in AS (p = 0.0005) than in controls. ET-1 positively correlated with ESR (p = 0.04) and Disease Activity Score 28 (DAS28, p = 0.003) in PsA. In spondyloarthritis, markers of endothelial function correlated with disease activity and TC.

Bone tissue metabolism in men with ankylosing spondylitis

PURPOSE The aim of the study was the composite estimation of bone tissue metabolism in ankylosing spondylitis (AS) after having taken into account such factors as a high risk of incidence of osteoporosis in patients with AS and potential danger of permanent immobility. MATERIAL AND METHODS Sixty-six patients with established diagnosis of AS and 63 healthy individuals in the control group were included into the study. To measure bone mineral density (BMD) the dual energy X-ray absorptiometry (DEXA) method was used. Additionally, biochemical markers of osteoporosis such as bone fraction of an alkaline phosphatase (BALP), osteocalcin (BGP) and deoxypyridinoline (Dpd) as well as many inflammatory markers of disease activity have been determined. RESULTS In our study with AS had significantly diminished bone mineral density, as compared with health controls. The presence of osteopenia/osteoporosis was associated with longer duration of the disease and with higher age. In the overall group of AS patients bone degradation marker, Dpd, correlated with serum concentration of interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha) and C-reactive protein (CRP), and inversely with BMD measured in the forearm. However, no direct association could be revealed between lower bone density and markers of inflammation or inflammatory cytokines, except of IL-6 witch was significantly higher in AS patients with osteoporosis/osteopenia than those without. CONCLUSIONS Our results indicate that disease duration and higher age are risk factors for osteoporosis in patients with AS. Inflammation might contribute to the accelerated bone loss in AS through stimulation of bone degradation.

Extra-Articular Symptoms in Constellation with Selected Serum Cytokines and Disease Activity in Spondyloarthritis

Objectives. In this study, we assessed the extra-articular symptoms in constellation with selected serum cytokines and disease activity in spondyloarthritis (SpA). Patients and Methods. We studied 287 SpA patients: 131 had AS, 110 had PsA, and 46 had SAPHO. We assessed extra-articular symptoms in all cases. In 191 SpA patients, we measured serum interleukin-6 (IL-6), interleukin-18 (IL-18), interleukin-23 (IL-23), endothelin-1 (ET-1), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF). Results. Patients with acute anterior uveitis (AAU) had higher VAS (P = 0.0008), BADSDAI (P = 0.0001), ASDAS-ESR (P = 0.04), CRP (P = 0.006), IL-6 (P = 0.02), and IL-18 (P = 0.03) levels. Patients with inflammatory bowel disease (IBD) had higher VAS (P = 0.03), CRP (P = 0.0009), and IL-6 (P = 0.0003) levels. Patients with skin psoriasis had lower VAS (P = 0.001) and BASDAI (P = 0.00007) levels. Patients with psoriatic onycholysis had lower VAS (P = 0.006), BASDAI (P = 0.00001), and CRP (P = 0.02) and higher IL-23 (P = 0.04) levels. Patients with PPP had lower BASDAI (P = 0.04) and higher ET-1 (P = 0.001) levels. Conclusions. SpA patients with increased serum IL-18 and decreased serum ET-1 had an increased risk of extra-articular symptoms. In SpA patients, increased disease activity was associated with an increased risk of AAU and IBD and a decreased risk of skin psoriasis, psoriatic onycholysis, and PPP.

Serum Interleukin-23 in Polish Patients with Systemic Lupus Erythematosus: Association with Lupus Nephritis, Obesity, and Peripheral Vascular Disease

Objectives To analyze the correlation between the serum concentration of interleukin- (IL-) 23 and atherosclerotic changes, traditional atherosclerotic risk factors, the autoantibody profile, and involvement of selected organs in systemic lupus erythematosus (SLE) patients. Patients and Methods We studied 94 SLE patients and 27 controls. We analyzed the IL-23 serum concentration, autoantibodies, carotid intima-media thickness and atherosclerotic plaque, the ankle-brachial index, atherosclerotic risk factors, and organ manifestations. Results Concentrations of IL-23 significantly differed between SLE patients and the controls (p = 0.0015). On the basis of multivariate stepwise analysis, we revealed that high levels of IL-23 were associated with atherosclerotic plaque in common femoral arteries (OR = 12.67; 95% CI: 1.41–113.84), lupus nephritis (OR = 3.69; 95% CI: 1.16–12.22), and obesity (OR = 4.21; 95% CI: 1.40–12.67). Autoantibodies related to IL-23 were anti-phosphatidylethanolamine antibodies (OR = 11.06; 95% CI: 1.24–98.65) and anti-SS-B/La antibodies (OR = 15.43; 95% CI: 1.73–137.25). Conclusions IL-23 may be involved in lupus nephritis pathogenesis. Through its association with obesity and selected antiphospholipid antibodies, IL-23 might promote a hypercoagulable state contributing to atherothrombosis development in SLE patients.

Arteriosclerosis or Vasculitis? Color Duplex Sonography in Giant Cell Arteritis

To the Editor: We followed with great interest the report by Czihal, et al 1 presenting new possibilities of objective, noninvasive diagnostic procedures that remain insufficient in giant cell arteritis (GCA). We would like to share our clinical experiences with arteritic changes in patients with GCA. Sonographic presentations of vasculitis may be mistaken for arteriosclerosis, especially in elderly patients who typically have GCA. That was the case in a patient with mild systemic manifestations and insidious disease onset. A 64-year-old woman presented with carotidynia — a rare manifestation of GCA. Color duplex sonography (CDS) revealed hypoechoic, homogenous, circumferential but not symmetrical bilateral wall thickening involving carotid and internal carotid arteries up to 15 mm from the carotid … Address correspondence to Dr. Milchert; E-mail: marcmilc{at}hotmail.com

Serum interleukin-23 protects, whereas methotrexate treatment stimulates selected components of the metabolic syndrome in patients with SAPHO syndrome

Introduction The aim of the study was to evaluate the impact of disease activity, selected serum cytokines, and therapy on metabolic syndrome (MetS) components in patients with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome. Material and methods We studied 46 SAPHO patients (40 women, 6 men). We recorded age, sex, disease duration, arthritis localization, type of skin changes, bone scintigraphy results, comorbidities, BASDAI, VAS, and treatment. We measured erythrocyte sedimentation rate, C-reactive protein, lipid profile, serum IL-6, IL-18, IL-23, endothelin-1, vascular endothelial growth factor, and epidermal growth factor (EGF). Results 97.8% of patients had sternoclavicular joint arthritis, 91.3% of patients palmoplantar pustulosis. In 65.2% of SAPHO patients skin changes and arthritis started simultaneously. Apart from non-steroidal anti-inflammatory drugs, patients were treated with methotrexate (41.3%), sulfasalazine (41.3%), and antibiotics (39.1%). 19.5% of patients met MetS criteria. Serum IL-23 correlated positively with total cholesterol (TC; p = 0.02) and high-density lipoprotein cholesterol (HDL-C) (p = 0.01) in the SAPHO group. There was a negative correlation between HDL-C and BASDAI (p = 0.02). Patients treated with methotrexate had higher triglyceride (p = 0.01) and low-density lipoprotein cholesterol (LDL-C) (p = 0.01) levels. There was a negative correlation between TC and EGF (p = 0.03). Increased prevalence of autoimmune diseases and depression was observed in SAPHO patients. Conclusions Serum IL-23 protects, whereas methotrexate treatment stimulates selected components of the MetS in patients with SAPHO syndrome.

Results from Polish Spondyloarthritis Initiative registry (PolSPI) – methodology and data from – the first year of observation

Objectives Report on one-year results from the Polish Spondyloarthritis Initiative registry (PolSPI), containing the cross-sectional analysis of clinical and imaging data as well as database methodology. Material and methods The PolSPI registry includes patients with axial (axSpA) and peripheral (perSpA) spondyloarthritis according to ASAS classification criteria, and/or patients with ankylosing spondylitis according to modified New York criteria, psoriatic arthritis according to CASPAR criteria, arthropathy in inflammatory bowel disease, reactive arthritis, juvenile spondyloarthritis or undifferentiated spondyloarthritis. Epidemiologic data and history of signs, symptoms and treatment of spondyloarthritis are collected and assessment of disease activity is performed. Radiographic images of sacroiliac joint, cervical and lumbar spine, and results of bone densitometry are collected. Every 6 months blood samples for inflammatory markers, and for long-term storage are taken. Results During a one-year period from September 2015 to August 2016, 63 patients were registered on an electronic database; 44 (69.8%) of patients were classified as axial spondyloarthritis (axSpA) and 19 (30.2%) as peripheral spondyloarthritis (perSpA) according to ASAS criteria. Statistically significant differences between axSpA and perSpA were discovered in the percentage of HLA-B27 antigen occurrence (92.6% and 50%, respectively), BASDAI (2.8% and 4.1%, respectively), DAS 28 (2.66% and 4.03%, respectively), percentage of peripheral arthritis (20% and 88.8%, respectively), enthesitis (26.7% and 70.6%, respectively), dactylitis (6.7% and 88.9%, respectively), as well as extra-articular symptoms: acute anterior uveitis (26.7% and 5.6%, respectively) and psoriasis (6.9% and 55.6%, respectively). Patients with axSpA had significantly higher mean grade of sacroiliac involvement according to New York criteria, higher mSASSS score, and lower T-score in femoral neck in bone densitometry. Conclusions At the early stage of the disease patients with axSpA compared to those with perSpA, have more advanced structural damage of sacroiliac joints and spine, and lower bone mineral density in the femoral neck. In the upcoming years the PolSPI registry will prospectively follow-up patients with SpA, recording response to treatment and carrying out research on interaction of inflammation and bone remodelling.

03.03 Serum interleukin 23 in polish patients with systemic lupus erythematosus – association with obesity and peripheral vascular disease

Background Cytokine-mediated immunity plays a crucial role in the pathogenesis of various autoimmune diseases including systemic lupus erythematosus (SLE). The aim of this study was to evaluate association between serum levels of IL-23 and vascular involvement in SLE patients. Materials and methods Study was performed in 94 SLE patients (82 women and 12 men) aged 19–73 years and in 27 age and gender matched controls. Serum IL-23 was measured with ELISA method using R and D Systems tests. Carotid intima-media thickness and the presence of atherosclerotic plaques in carotid and lower extremities arteries were analysed with B-mode ultrasound. Ankle-brachial and high resistance indexes were measured with Doppler ultrasonography. We took into account classical cardiovascular risk factors (hypertension, dyslipidemia, hyperglycemia, overweight/obesity, smoking, oral contraceptives, positive family history of cardiovascular disease), selected clinical manifestations (cardiovascular, cerebrovascular, lupus nephritis, Raynaud’s phenomenon, livedo reticularis, vasculitis, other thromboembolic complications), profile of autoantibodies (antinuclear, antiphospholipid, anti-neutrophil cytoplasmic, anti-endothelial cell). Statistical analysis was performed with: chi 2Yates, chi 2Pearson, rank Spearman correlations tests, logistic regression analysis and multivariate stepwise analysis. Results Concentrations of IL-23 significantly differed between SLE patients and the controls (p=0.0005). Patients with high levels of IL-23 more frequently developed atherosclerosis showed as the presence of plaques in right common femoral artery (OR=10.1; 95% CI:1.2–85.1) and lupus nephritis (OR=3.2; 95% CI:1.1–9.6). Among classical atherosclerotic risk factors only obesity was significantly associated with IL-23 (OR=3.8; 95% CI:1.2–12.3). Immunological characteristics significantly related to IL-23 were anti-phosphatidylethanolamine antibodies (OR=12.7; 95% CI:1.5–108.1) and anti-SS-B antibodies (OR=11.8; 95% CI:1.5–94.8). Association with anti-cardiolipin and anti-prothrombin antibodies was on the border of statistical significance (OR=2.3; 95% CI:0.9–5.7 and OR=8.4; 95% CI:1.0–71.1 respectively). Conclusions IL-23 may be involved in lupus nephritis pathogenesis. 2. IL-23 through its significant association with obesity and antiphospholipid antibodies may promote hypercoagulable state contributing to atherothrombosis development in SLE patients.
