Combined use of QRISK3 and SCORE2 increases identification of ankylosing spondylitis patients at high cardiovascular risk: Results from the CARMA Project cohort after 7.5 years of follow-up.

OBJECTIVE: To establish the predictive value of the QRESEARCH risk estimator version 3 (QRISK3) algorithm in identifying Spanish patients with ankylosing spondylitis (AS) at high risk of cardiovascular (CV) events and CV mortality. We also sought to determine whether to combine QRISK3 with another CV risk algorithm: the traditional SCORE, the modified SCORE (mSCORE) EULAR 2015/2016 or the SCORE2 may increase the identification of AS patients with high-risk CV disease. METHODS: Information of 684 patients with AS from the Spanish prospective CARdiovascular in ReuMAtology (CARMA) project who at the time of the initial visit had no history of CV events and were followed in rheumatology outpatient clinics of tertiary centers for 7.5 years was reviewed. The risk chart algorithms were retrospectively tested using baseline data. RESULTS: After 4,907 years of follow-up, 33 AS patients had experienced CV events. Linearized rate=6.73 per 1000 person-years (95 % CI: 4.63, 9.44). The four CV risk scales were strongly correlated. QRISK3 correctly discriminated between people with lower and higher CV risk, although the percentage of accumulated events over 7.5 years was clearly lower than expected according to the risk established by QRISK3. Also, mSCORE EULAR 2015/2016 showed the same discrimination ability as SCORE, although the percentage of predicted events was clearly higher than the percentage of actual events. SCORE2 also had a strong discrimination capacity according to CV risk. Combining QRISK3 with any other scale improved the model. This was especially true for the combination of QRISK3 and SCORE2 which achieved the lowest AIC (406.70) and BIC (415.66), so this combination would be the best predictive model. CONCLUSIONS: In patients from the Spanish CARMA project, the four algorithms tested accurately discriminated those AS patients with higher CV risk and those with lower CV risk. Moreover, a model that includes QRISK3 and SCORE2 combined the best discrimination ability of QRISK3 with the best calibration of SCORE2.

Tocilizumab-related hypertriglyceridemia is independent of key molecules regulating lipid metabolism.

INTRODUCTION: Tocilizumab (TCZ) treatment is associated with dyslipidaemia, including a rise in triglycerides through a mechanism poorly understood. Three molecules play key roles in the regulation of triglyceride metabolism: apolipoprotein C-III (ApoC-III), angiopoietin-like protein 4(ANGPLT4) and lipoprotein lipase (LPL). The aim of this work was to analyse whether the changes in triglycerides shown by TCZ-treated RA patients could stem from the dysregulation that can occur in these regulatory molecules. METHODS: Twenty-seven RA patients included in the TOCRIVAR study who received TCZ (8 mg/kg IV/q4w) were evaluated at baseline and at Weeks 12, 24 and 52 of treatment. ANGPTL4, ApoC-III and LPL, a complete lipid profile and RA disease activity, were analysed at baseline and at each visit. Multivariable linear mixed models were performed to study changes over time in lipids and regulatory molecules. RESULTS: After 24 weeks of TCZ treatment, HDL cholesterol, apolipoprotein A1 and triglycerides increased, whereas lipoprotein (a) decreased significantly from baseline values. However, 1 year after TCZ, no significant differences in lipid pattern were observed with respect to baseline. Serum ANGPTL4 and Apo-CIII levels decreased gradually over time, both being significantly lower than baseline values at Week 52. LPL concentration did not change significantly during TCZ treatment. Remarkably, the elevation of triglycerides at Week 24 maintained its statistical significance after adjusting for the changes in ApoC-III, ANGPTL4 and LPL. CONCLUSION: In TCZ-treated RA patients basal serum levels of ANGPLT4 and ApoC-III, but not LPL, decreased significantly. However, the elevation of triglycerides after TCZ was not related to changes in these regulatory molecules.

Myo-Spain: Spanish Registry of patients with idiopathic inflammatory myopathy. Methodology.

OBJECTIVES: To describe the methods of the Spanish Registry of patients with idiopathic inflammatory myopathy (IIM) (Myo-Spain), as well as its strengths and limitations. The main objective of the project is to analyse the evolution and clinical management of a cohort of patients with IIM. METHODS: Observational, longitudinal, ambispective and multicentre study of a cohort of patients with IIM seen in rheumatology units in Spain. All patients with a diagnosis of IMM will be included in the regular follow-up of the participating centres, regardless of age on initiation of the process. Incident cases will be all patients who at the beginning of the study have been diagnosed for less than 12 months and prevalent cases for more than 12 months. The registry will include data from the visit at baseline, one year and two years. Socio-demographic, clinical, analytical variables, complications, comorbidities, association with other rheumatic diseases, hospital admissions, mortality and treatments will be collected. In addition, indices, scales and questionnaires of activity, muscle involvement, damage, disability, and quality of life will be determined. The recruitment period will be 23 months. The purpose is to obtain a cohort of 400 patients with IMM. CONCLUSIONS: Myo-Spain registry provides the opportunity to develop a cohort of incident and prevalent patients with IMM in Spain. Myo-Spain will be able to assess in detail the clinical characteristics of the disease at different times. The comprehensive information collected during the visits is expected to provide a broad source of data for future analysis.

HDL cholesterol efflux capacity and lipid profile in patients with systemic sclerosis.

OBJECTIVE: It is well established that patients with systemic sclerosis (SSc) have a disrupted lipid profile and an increased cardiovascular risk. Cholesterol efflux capacity (CEC), the ability of high-density lipoprotein (HDL)-cholesterol to accept cholesterol from macrophages, has been linked to cardiovascular events. The aim of this study was to establish whether CEC and lipid profile were impaired in SSc patients with respect to controls and whether these changes were associated with disease-related data. METHODS: Cross-sectional study encompassed 188 individuals: 73 SSc patients and 115 controls. CEC, using an in vitro assay, and lipoprotein serum concentrations were assessed in patients and controls. A multivariable analysis was performed to study the differences in CEC between patients and controls, and if SSc-related data could explain such differences. RESULTS: The multivariable analysis adjusted for demographic characteristics, cardiovascular risk factors, and lipid-related molecules showed that total cholesterol (beta coefficient: - 22 [95%CI - 37 to - 7], p = 0.004), triglycerides (beta coefficient: 24 [95%CI 2-47], p = 0.033), lipoprotein A (beta coefficient: 22 [95%CI 2-43], p = 0.033), and CEC (beta coefficient: - 6 [95%CI - 10 to - 2]%,p = 0.002) were significantly different between patients and controls. Skin thickness, as assessed by modified Rodnan skin score, was independently associated with a lower CEC (beta coefficient: - 0.21 [95%CI - 0.37 to - 0.05]%, p = 0.011) after multivariable adjustment. CONCLUSION: SSc patients show an abnormal lipid profile with respect to controls including CEC. Skin thickness is independent and inversely associated with CEC in SSc patients.

Proprotein convertase subtilisin/kexin type 9 in patients with systemic sclerosis.

OBJECTIVES: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a serine protease that regulates cholesterol metabolism through low-density lipoprotein receptor degradation, and which has been linked to cardiovascular risk. The purpose of the present study was to examine whether PCSK9 serum levels are disrupted in patients with systemic sclerosis (SS) compared to controls, and if PCSK9 is related to disease-related data and the subclinical atherosclerosis that occurs in these patients. METHODS: Cross-sectional study that encompassed 146 individuals; 73 patients with SS and 73 age- and sex-matched controls. PCSK9, lipoproteins serum concentrations, and standard lipid profiles were assessed in patients and controls. Carotid intima-media thickness (cIMT) and the presence of carotid plaques were evaluated in SS patients. A multivariable analysis, adjusted for traditional cardiovascular risk factors, was performed to evaluate the differences in PCSK9 between patients and controls, the association of SS-related manifestations with PCSK9 levels, and if PCSK9 was associated with subclinical carotid atherosclerosis in SS patients. RESULTS: After multivariable analysis, PCSK9 was downregulated in SS patients compared to controls (beta coefficient -78 (95%CI -106 - -50) ng/ml, p=0.000) and skin thickness was associated with higher serum levels of PCSK9 (beta coef. 22 (7-37) units, p=0.005). PCSK9 was significantly and positively associated with cIMT (beta coef. 0.65 (0.06-1.24) ng/ml, p=0.031) in SS patients after multivariable adjustment. CONCLUSIONS: PCSK9 serum concentration is downregulated in SS patients compared to controls and is directly associated with disease severity subrogated parameters. PCSK9 was independently related to cIMT in SS patients.

Reclassification into very-high cardiovascular risk after carotid ultrasound in patients with axial spondyloarthritis.

OBJECTIVES: Subclinical atherosclerosis, defined as the presence of carotid plaques, is more frequently found in patients with axial spondyloarthritis (axSpA) than in healthy individuals. We sought to determine whether axSpA patients are more commonly reclassified into the very high cardiovascular risk category than controls after performing carotid ultrasound and if this can be linked to disease characteristics. METHODS: 343 patients diagnosed with axSpA according to ASAS criteria and 177 controls were studied. Disease characteristics and Systematic Coronary Risk Evaluation (SCORE) were assessed in patients and controls. Presence of plaques and intima-media thickness (cIMT) was determined by carotid ultrasound. Multivariable regression analysis was performed to identify differences in the frequency of reclassification between patients and controls, as well as factors associated with reclassification in axSpA. RESULTS: Carotid plaques (36% vs.25%, p=0.010) and higher cIMT (0.641± 0.121 vs. 0.602± 0.115 mm, p=0.001) were more common in patients than controls. Reclassification into the high-risk category was greater in patients (34% vs. 25%, p=0.037). Age (beta coefficient 2.74 [95%CI 1.34-5.62] vs. beta coef. 0.63 (95%CI 0.40-0.99) in patients, interaction p=0.001) and serum LDL-cholesterol (beta coef. 1.03 [95%CI 1.02-1.04] vs. beta coef. 1.00 [0.99-1.01], interaction p=0.029) showed a higher effect on reclassification in controls after multivariable analysis. Although reclassification in axSpA was associated with higher ASDAS-CRP, BASFI and BASMI scores, these associations were lost after adjusting for cardiovascular risk factors. CONCLUSIONS: Patients with axSpA are more likely to be reclassified into the very-high risk category after carotid ultrasound than controls. The influence of traditional cardiovascular risk factors on this reclassification differs between patients and controls.

Association of apolipoprotein B/apolipoprotein A1 ratio and cardiovascular events in rheumatoid arthritis: results of the CARMA study.

OBJECTIVES: To assess the plasma apolipoprotein B/apolipoprotein A1 ratio and its potential association with cardiovascular events (CVE) in patients with rheumatoid arthritis (RA). METHODS: A baseline analysis was made of the CARdiovascular in rheuMAtology Project (CARMA), a 10-year prospective study evaluating the presence of at least one CVE in 775 Spanish patients with RA. Of them, 29 had already experienced CVE prior to the inclusion in the study. We assessed the association between the elevation of the apoB/apoA1 ratio with the presence of CVE according to a logistic regression model for possible confounding factors. We also analysed the main parameters of activity of RA and parameters related to lipid metabolism. RA patients were classified according to treatment: patients treated with disease-modifying anti-rheumatic drugs without biologics and those undergoing biologic therapy (anti-TNF-α, anti-IL-6 receptor, and other biologic agents). RESULTS: The apoB/apoA1 ratio of patients who had experienced CVE was higher than that of patients without previous CVE (0.65 vs. 0.60). However, the difference between both subgroups did not reach statistical significance (p=0.197). It was also the case after the multivariate analysis [OR: 1.48 (95% CI: 0.15-14.4); p=0.735]. RA patients from the group with CVE were more commonly receiving lipid-lowering treatment with statins than those without CVE history (41.4% vs. 20%, p=0.005). High HAQ and high atherogenic index were significantly associated with the presence of CVE. There was no statistical association between the type of biologic therapy used in RA and the presence of CVE. CONCLUSIONS: No association between ApoB/apoA1 ratio and CVE was found at the baseline visit of patients with RA from the CARMA study.

Effect of IL-6 Receptor Blockade on Proprotein Convertase Subtilisin/Kexin Type-9 and Cholesterol Efflux Capacity in Rheumatoid Arthritis Patients.

The aim of the work was to examine whether abnormalities in the lipid profile that tocilizumab (TCZ), an anti-IL-6 receptor Ab, exerts in rheumatoid arthritis (RA) patients is related to changes in either proprotein convertase subtilisin/kexin-9 (PCSK9) serum concentrations or in serum cholesterol efflux capacity (CEC). TOCRIVAR is a one-year prospective clinical trial that analyzes the influence of TCZ on cardiovascular risk factors. Twenty-seven RA patients receiving TCZ (8 mg/kg IV/q4w) were assessed at baseline and weeks 12, 24, and 52. Disease activity indexes, adiposity composition, physical activity, serum CEC, PCSK9, and lipoproteins serum concentrations were assessed at every visit. Basal high-sensitivity C-reactive protein (hs-CRP) and disease activity were markedly reduced throughout one-year TCZ treatment. While initially total cholesterol and LDL cholesterol increased their plasma concentration, decreasing to basal afterwards, lipoprotein(a) was significantly lower than basal in all visits of the study. CEC increased after 24 week of treatment proportionally to hs-CRP reduction, and remained significantly higher after week 52 [median % change 32 (3-141), p=0.021]. Interestingly, variations in LDL cholesterol basal concentration along the one year of TCZ treatment correlated directly with changes of PCSK9 serum concentration (r=0.37, p=0.003). Basal abdominal adiposity, BMI, and physical activity remained stable during the study. Long-term TCZ-treated RA patients show an increment in CEC inversely proportional to hs-CRP reduction and changes in LDL cholesterol that might be explained, at least in part, by variations in PCSK9 plasma concentration. Overall, TCZ treatment produces a favorable qualitative net effect in terms of atherogenic implication in RA patients.

Relationship of abdominal adiposity and body composition with endothelial dysfunction in patients with rheumatoid arthritis.

OBJECTIVES: We aimed to investigate whether the abnormalities in body composition and abdominal fat that occur in rheumatoid arthritis (RA) are associated with the presence of endothelial dysfunction. METHODS: Cross-sectional study that encompassed 197 women (100 RA patients and 97 age-matched controls). Patients and controls were evaluated to establish endothelial function by brachial artery flow-mediated dilatation (FMD). Dual-x-ray-absorptiometry-derived body composition and abdominal adiposity by magnetic resonance imaging were assessed. Multiple regression analysis was performed to study the relationship between body composition and endothelial function. RESULTS: FMD was higher in controls compared to RA patients (8.5 [4.5-15.6] % vs. 5.3 [0.0-9.2] %, p=0.00). Appendicular-to-total lean mass ratio (0.42 ± 0.02 vs. 0.40 ± 0.03, p=0.00) and appendicular-to-trunk lean mass (0.82 ± 0.08 vs. 0.78 ± 0.08, p=0.00) were lower in RA patients. Visceral and subcutaneous abdominal fat tissues did not differ between patients and controls. Body mass index over 30 kg/m2 was common in patients and controls (44 and 32%). High sarcopenia tended to be more elevated in RA after multivariate adjustment (13% vs. 7%, p=0.06). Fat mass index showed a negative association (per standard deviation-SD-), after adjusting for comorbidity, with FMD in controls (beta coef. -0.45[-1.05-0.05], p=0.03) but not in patients. Overfat definition (beta coef. -0.81[-1.73-0.00], p=0.05) and visceral fat (per SD beta coef. -0.60 [-1.18-0.02], p=0.04) were associated with a lower FMD values in controls but not in RA patients. Trend analysis revealed that sarcopenia was related to increased endothelial dysfunction in both patients and controls. CONCLUSIONS: Our findings suggest that fat accumulation is not associated with endothelial dysfunction in RA patients. However, RA patients with sarcopenia are more likely to suffer endothelial dysfunction possibly being at higher cardiovascular risk.

Analysis of the association between CD40 and CD40 ligand polymorphisms and systemic sclerosis.

INTRODUCTION: The aim of the present study was to investigate the possible role of CD40 and CD40 ligand (CD40LG) genes in the susceptibility and phenotype expression of systemic sclerosis (SSc). METHODS: In total, 2,670 SSc patients and 3,245 healthy individuals from four European populations (Spain, Germany, The Netherlands, and Italy) were included in the study. Five single-nucleotide polymorphisms (SNPs) of CD40 (rs1883832, rs4810485, rs1535045) and CD40LG (rs3092952, rs3092920) were genotyped by using a predesigned TaqMan allele-discrimination assay technology. Meta-analysis was assessed to determine whether an association exists between the genetic variants and SSc or its main clinical subtypes. RESULTS: No evidence of association between CD40 and CD40LG genes variants and susceptibility to SSc was observed. Similarly, no significant statistical differences were observed when SSc patients were stratified by the clinical subtypes, the serologic features, and pulmonary fibrosis. CONCLUSIONS: Our results do not suggest an important role of CD40 and CD40LG gene polymorphisms in the susceptibility to or clinical expression of SSc.

Central retinal artery occlusion in Wegener's granulomatosis: a diagnostic dilemma.

PURPOSE: To report a case of central retinal artery occlusion (CRAO) in a patient with biopsy-verified Wegener's granulomatosis (WG) with positive C-ANCA. METHODS: A 55-year-old woman presented with a 3-day history of acute painless bilateral loss of vision; she also complained of fever and weight loss. Examination showed a CRAO in the left eye and angiographically documented choroidal ischemia in both eyes. RESULTS: The possibility of systemic vasculitis was not kept in mind until further studies were carried out; methylprednisolone pulse therapy was then started. Renal biopsy disclosed focal and segmental necrotizing vasculitis of the medium-sized arteries, supporting the diagnosis of WG, and cyclophosphamide pulse therapy was administered with gradual improvement, but there was no visual recovery. CONCLUSION: CRAO as presenting manifestation of WG, in the context of retinal vasculitis, is very uncommon, but we should be aware of WG in the etiology of CRAO. This report shows the difficulty of diagnosing Wegener's granulomatosis; it requires a high index of suspicion, and we should obtain an accurate medical history and repeat serological and histopathological examinations. It emphasizes that inflammation of arteries leads to irreversible retinal infarction, and visual loss may occur.
