Background:Bilirubin has been recognized as a potential endogenous inhibitor of atherosclerosis, being inversely associated with carotid intima-media thickness (CIMT). However, little information is available concerning the correlation between serum indirect bilirubin (IBIL), especially long-term IBIL level, and early atherosclerosis progression. This study was designed to evaluate the relationship between serum IBIL level and CIMT progression.Methods:A total of 2205 participants were enrolled in this Asymptomatic Polyvascular Abnormalities Community study (APAC study). CIMT was measured at baseline and 2-year follow-up. The participants were divided into four groups based on their serum IBIL levels at baseline. Both baseline and average serum IBIL values during the 2-year follow up were used in the analysis. Multivariable logistic regression and linear regression were used to assess the associations between serum IBIL and CIMT progression.Results:The results showed that 51.93% (1145/2205) of participants were diagnosed with CIMT progression during the 2-year follow-up. Baseline serum IBIL level was significantly associated with the incidence of CIMT progression after adjusting for other potential confounding factors. Compared with the first quartile, adjusted odds ratios (OR) of the second, third, and fourth quartiles of IBIL were 0.70 [95% confidence interval (CI), 0.55-0.90], 0.68 (95% CI, 0.52-0.87), and 0.63 (95% CI, 0.49-0.82) (P = 0.0006), respectively. Serum IBIL level during the follow-up was also associated with CIMT progression in the univariate analysis (P = 0.0022), although no longer significant after adjusting for potential confounders in the multiple linear regression.Conclusion:The study demonstrated the inverse relationship between serum IBIL and CIMT progression. Lower serum IBIL level is an independent predictor of subclinical atherosclerosis.

The Impact

Carotid artery intima-media thickness (CIMT) assessed by B-mode ultrasound is an accepted marker for subclinical atherosclerosis commonly used in clinical trials. Their sample size and power calculations apply 2-sample independent t-tests and within group variance in progression rates from the literature. However, this approach obscures the impact of differences in study designs including length of follow-up and differences in the number of and interval between ultrasound scans. These effects can be assessed using common sample size formula for longitudinal models, but this approach requires decomposition of the total variance into between and within subject components that have not generally been reported in the literature. Here, we derive these variance components for the Measuring Effects on intima-media Thickness: an Evaluation of Rosuvastatin (METEOR) study, a randomized, double-blind trial that demonstrated treatment with 40 mg rosuvastatin significantly slowed CIMT progression in middle-aged patients with a low Framingham risk of coronary heart disease and subclinical atherosclerosis (baseline maximum CIMT ≥1.2-<3.5mm). We examined the impact of differing follow-up periods, use of intermediate scans, and use of duplicate scans using both sample size calculations and actual analyses based on subsets of the METEOR data. Reductions in study length or number of scans result in increased variances and larger sample sizes to detect a given treatment effect. Table shows the impact of duplicate scans at baseline and end of the 2-year study, with and without intermediate scans performed every 6 months, on the sample size required to detect a treatment effect of 0.012 mm/year. These results underscore the importance of considering the number and spacing of ultrasound exams explicitly during study design, and suggest that reductions in scanning frequency may seriously erode study power and/or increase costs by requiring recruitment of additional subjects.

Atherogenic lipoproteins (particularly, very low-density lipoproteins, VLDL) are associated with subclinical atherosclerosis. The present study aims at evaluating whether routinely analysed lipid parameters are associated with carotid intima–media thickness, a proxy for subclinical atherosclerosis. Lipid parameters from 220 post-menopausal women undergoing ultrasound investigation of the carotid arteries were analysed. Forty-five percent of women showed subclinical atherosclerosis on carotid ultrasound. The mean carotid intima–media thickness was 1.26 ± 0.38 mm. The mean value of the non-HDL-C/HDL-C ratio was 3.1 ± 1.2. Univariate analysis showed a significant association between non-HDL-C/HDL-C ratio and intima–media thickness (r = 0.21, p = 0.001). After adjusting for cardiovascular risk factors (age, systolic blood pressure, smoking, body mass index Homeostasis model assessment: insulin resistance and high-sensitivity C-Reactive-Protein), multivariate analysis showed a significant association between non-HDL-C/HDL-C ratio and intima–media thickness (β = 0.039, p = 0.04). Logistic regression analysis showed that the highest tertile of the non-HDL-C/HDL-C ratio was associated with the presence of carotid plaques (OR = 3.47, p = 0.003). Finally, a strong correlation between non-HDL-C/HDL-C ratio and cholesterol bound to VLDL (r = 0.77, p < 0.001) has been found. Non-HDL-C/HDL-C ratio is associated with the presence of carotid atherosclerosis in post-menopausal women and is strongly correlated to VLDL-C levels.

ObjectiveTo compare progression of subclinical atherosclerosis and factors promoting it in patients with SLE and controls.MethodsConsecutive patients with SLE and age-matched, sex-matched population controls from the SLEVIC cohort were assessed at inclusion and after 7 years with standardised data collection and carotid ultrasound. Effect of risk factors on carotid intima–media thickness (cIMT) progression was examined with adjusted linear mixed models.ResultsA total of 77 patients and 74 controls, 68% and 61% of the original cohort, completed follow-up. The patients were (mean) 47 years old, 90% were women, and controls were 51 years old, 92% women. Patients had disease duration of (mean) 11 years, mild disease activity and low severity at both assessments. Baseline cIMT did not differ between the groups. An average absolute cIMT progression was 0.009 mm/year in patients and 0.011 mm/year in controls, intergroup difference p=0.9.Of factors at inclusion, dyslipidaemia, lower levels of high-density lipoprotein (HDL) and carotid plaque in patients and controls, and higher systolic blood pressure, total cholesterol:HDL and LDL:HDL ratios and triglycerides in patients were associated with cIMT progression. Of factors at follow-up, hypertension and blood lipids in patients and HDL in controls were significantly associated with cIMT progression. History of lupus nephritis and a higher average dose of prednisolone used since diagnosis were associated with cIMT progression in patients. Associations of risk factors with cIMT progression were stronger in presence of plaques.ConclusionWe observed a statistically comparable progression of cIMT in patients with mild SLE and controls over 7 years, which implies that progression of subclinical atherosclerosis in some patients with SLE could follow that of the general population. Traditional cardiovascular (CV) risk factors, history of lupus nephritis and higher use of corticosteroids promote cIMT progression in SLE. Detection of carotid plaque may add to CV risk stratification.

CONTEXT AND OBJECTIVE Accelerated atherosclerosis has become a major problem in rheumatic inflammatory disease. The aim here was to analyze carotid intima-media thickness (IMT) in spondyloarthritis (SpA) patients and correlate this with clinical parameters and inflammatory markers. DESIGN AND SETTING Cross-sectional analytical study at Rheumatology Outpatient Clinic, Evangelical University Hospital, Curitiba. METHODS IMTs (measured using Doppler ultrasonography) of 36 SpA patients were compared with controls. The IMT in SpA patients was associated with inflammatory markers, like erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); and with clinical parameters, like axial or peripheral involvement, dactylitis, HLA B27, uveitis occurrence, Bath Ankylosing Spondylitis Functional Index (BASFI) and lipid profile. RESULTS The mean IMT in SpA patients was 0.72 ± 0.21 mm; in controls, 0.57 ± 0.13 mm (P = 0.0007). There were no associations with ESR, CRP, BASDAI or clinical data. In univariate analysis, greater IMT was seen in patients with longer disease duration (P = 0.014; Pearson R = 0.40; 95% confidence interval, CI = 0.06 to 0.65); higher triglycerides (P = 0.02; Spearman R = 0.37; 95% CI = 0.03 to 0.64); and older age (P = 0.0014; Pearson R 0.51; 95% CI = 0.21 to 0.72). CONCLUSION SpA patients have a higher degree of subclinical atherosclerosis than in controls, thus supporting clinical evidence of increased cardiovascular risk in rheumatic patients.

Abstract Background: Subclinical atherosclerosis in childhood can be evaluated by carotid intima-media thickness, which is considered a surrogate marker for atherosclerotic disease in adulthood. The aims of this study were to evaluate carotid intima-media thickness and, to investigate associated factors. Methods: Cross-sectional study with children and adolescents with congenital heart disease (CHD). Socio-demographic and clinical characteristics were assessed. Subclinical atherosclerosis was evaluated by carotid intima-media thickness. Cardiovascular risk factors, such as physical activity, screen time, passive smoke, systolic and diastolic blood pressure, waist circumference, dietary intake, lipid parameters, glycaemia, and C-reactive protein, were also assessed. Factors associated with carotid intima-media thickness were analysed using multiple logistic regression. Results: The mean carotid intima-media thickness was 0.518 mm and 46.7% had subclinical atherosclerosis (carotid intima-media thickness ≥ 97th percentile). After adjusting for confounding factors, cyanotic CHD (odds ratio: 0.40; 95% confidence interval: 0.20; 0.78), cardiac surgery (odds ratio: 3.17; 95% confidence interval: 1.35; 7.48), and be hospitalised to treat infections (odds ratio: 1.92; 95% confidence interval: 1.04; 3.54) were associated with subclinical atherosclerosis. Conclusion: Clinical characteristics related to CHD were associated with subclinical atherosclerosis. This finding suggests that the presence of CHD itself is a risk factor for subclinical atherosclerosis. Therefore, the screen and control of modifiable cardiovascular risk factors should be made early and intensively to prevent atherosclerosis.

AbstractCommon carotid intima-media thickness (cIMT) is an index of subclinical atherosclerosis that is associated with ischemic stroke and coronary artery disease (CAD). We undertook a cross-sectional epigenome-wide association study (EWAS) of measures of cIMT in 6400 individuals. Mendelian randomization analysis was applied to investigate the potential causal role of DNA methylation in the link between atherosclerotic cardiovascular risk factors and cIMT or clinical cardiovascular disease. The CpG site cg05575921 was associated with cIMT (beta = −0.0264, p value = 3.5 × 10–8) in the discovery panel and was replicated in replication panel (beta = −0.07, p value = 0.005). This CpG is located at chr5:81649347 in the intron 3 of the aryl hydrocarbon receptor repressor gene (AHRR). Our results indicate that DNA methylation at cg05575921 might be in the pathway between smoking, cIMT and stroke. Moreover, in a region-based analysis, 34 differentially methylated regions (DMRs) were identified of which a DMR upstream of ALOX12 showed the strongest association with cIMT (p value = 1.4 × 10–13). In conclusion, our study suggests that DNA methylation may play a role in the link between cardiovascular risk factors, cIMT and clinical cardiovascular disease.

Background:The mechanism of increased cardiovascular risk in RA is not well understood and is independent of traditional CV risk factors. Intima-media thickness of the common carotid wall measured by ultrasonogram is a safe and useful biomarker of early stage atherosclerosis that correlates with coronary involvement; and it correlates with severity and duration of disease. Several studies have shown a relationship between inflammation markers, endothelial dysfunction markers, and carotid involvement. (1)Objectives:To determine the presence of inflammation biomarkers and its relationship with subclinical atherosclerosis measured by carotid ultrasound, and with the clinical characteristics in patients with established Rheumatoid Arthritis (RA)Methods:Descriptive, cross sectional, prospective study, in a Paraguayan cohort of patients with RA meeting ACR/EULAR2010 criteria. This study had two phases: the first one, included a standardized questionnaire according to the variables included in the Cardiovascular Risk project (PINV15-0346), from the National Sciences and Technology Council (CONACYT), and physical examination; the second one included laboratory sample collection performed by a specialized laboratory for serum biomarkers measurement for cardiovascular risk prediction (i.e endothelin, alpha-TNF, E-selectin, homocysteine, apolipoprotein, fibrinogen, and high sensitivity-CRP levels) and carotid ultrasound evaluation by a trained specialist, to evaluate subclinical atherosclerosis. Subclinical atherosclerosis was defined as carotid intima-media thickness (CIMT) >0,9mm and/or presence of carotid plaques. All patients signed informed consent. SPSS 23rd version was used for data analysis. Quantitative variables were presented as means and qualitative as frequencies. Chi square test was performed for comparisons between dichotomous variables and t Student for continuous, and p ≤ 0.05 for statistical significance.Results:100 patients were included, 87% were women, mean disease duration 130.9±102.64 months, 77% were RF positive, and 84.4% were ACPA positive, 43.4% had bone erosions, mean ESR-DAS28 was 3,42±1,1; 30% had remission criteria. 39% had extra-articular manifestations.Elevated serum biomarkers were found: fibrinogen >400 mg/dL 88.2%, high sensitivity-CRP (hs-CRP) >5mg/dL 42.9%, endothelin >2 ng/mL 20%, alpha-TNF >15,6 pg/mL 13.1%, E-selectin >79,2 ng/mL 6%. 25.3% had CIMT >0,9 mm and mean CIMT was 0.68±0.25mm. 27.14% had carotid plaques. Patients with CIMT>1mm had higher frequency of family history of arterial hypertension (p=0.006), greater mean disease duration (p=0.0007), hip circumference (p=0.014), blood pressure (SBP p=0.038, DBP p=0.027), HAQ levels (p=0,019) and hs-CRP levels (p=0.013), also lower mean height (p=0,04); while carotid plaques were related to higher homocysteine (p=0.026) and hs-CRP levels (p=0.024).Conclusion:A considerable percentage of patients had subclinical atherosclerosis. Patients with CIMT>0,9mm had a longer disease duration, higher HAQ levels, hip circumference, as well as higher BP. High levels of hs-CRP were more frequently related to the presence of subclinical atherosclerosisReferences:[1]Aday, A. targeting residual inflammatory risk: a shifting paradigm for atherosclerotic disease.
