Screening for subclinical atherosclerosis in patients clinically diagnosed with familial hypercholesterolemia and determination of imaging-guided patient management strategy

Abstract Introduction Familial hypercholesterolemia (FH) is a monogenic dyslipidemia characterized by elevated plasma LDL-C levels, leading to early cardiovascular disease. The Dutch Lipid Clinic Network (DLCN) score is the most widely used clinical scoring system in current practice. Subclinical atherosclerosis is defined as the detection of atheromatous plaques in arterial territories, such as coronary, carotid or iliofemoral, before a symptom or event occurs. It is an early indicator of atherosclerotic burden. In this study, we investigated the presence of subclinical atherosclerosis in FH patients with a definite or probable clinical diagnosis according to DLCN score. We also tried to identify independent predictors of subclinical atherosclerosis. Methods This study is a single-center, prospective, and cross-sectional investigation involving a cohort of 215 FH patients. These patients are primary prevention patients and among them, 120 patients received a definite clinical diagnosis, while 95 patients received a probable clinical diagnosis based on the DLCN score. Carotid USG and Femoral USG were performed to screen for subclinical atherosclerosis and CAC score was calculated by non-contrast CT. Apo A-I, Apo B and Lp (a) measurements were analyzed by immunonephelometric method. Results The study population consisted of 136 (63%) women and 79 (37%) men. The mean age was 54 years (43-62) and the stigmata rate was 18%. Initially, 17% of patients were on aspirin, and 32% were receiving statin treatment; however, following subclinical atherosclerosis screening, these proportions significantly increased (aspirin usage to %32 and statin usage to %96) within the population. 148 patients (69%) had subclinical atherosclerosis in at least one site. Upon regional analysis, subclinical atherosclerosis rates were 48% in the coronary arteries, 47.5% in the carotid bifurcation region, and 40.5% in the femoral bifurcation region. Additionally, 25% of patients had atherosclerosis at one site, 27% at two sites, and 17% at all three sites. Age, male gender, pretreatment LDL-C level, Apo A-I/Apo B ratio and DM were identified as independent predictors of the presence of subclinical atherosclerosis in the FH patients. Furthermore age, male gender, pretreatment nonHDL-C level, Lp (a) ≥ 30 mg/dl and presence of femoral plaque were identified as independent predictors of coronary atherosclerosis. Conclusion Subclinical atherosclerosis is prevalent among FH patients, and this study has identified independent predictors associated with presence of subclinical atherosclerosis. However, despite this heightened risk, medication utilization among these patients remains below optimal levels and only a small proportion of the population has achieved their treatment goals. Our study highlights the influence of subclinical atherosclerosis on treatment approaches, as demonstrated by the notable rise in statin and aspirin utilization observed after screening.Clinical and biochemical characteristicsSubclinical Atherosclerosis Rates

Cumulative effect of lifetime smoking history on arterial stiffness and subclinical atherosclerosis in patients with arterial hypertension

Abstract Introduction Although the effect of smoking status on blood pressure (BP) changes is well known an adverse association between cumulative smoke exposure (by pack-years) and functional and structural changes in arteries of patients with high BP has not been consistently demonstrated. Aim of the study was to explore the contributions of cumulative smoke exposure to the vascular consequences of arterial hypertension. Methods Indices of vascular function and structure including carotid-femoral pulse wave velocity (PWV), augmentation index (AIx) and carotid intima media thickness (cIMT) were measured in 485 adults aged less than 60 years old without a history of cardiovascular disease. The cohort was divided into three groups according to office systolic BP (SBP) and diastolic BP (DBP): normal (SBP <130 and DBP <85 mmHg, n=242), high normal (130≤SBP<140 or DBP 85≤DBP<90mmHg, n=96), and hypertension (SBP≥140 or DBP≥90mmHg, n=147). The cohort was subdivided according to pack-years of smoking history as never smokers (0.0 pack-years), light smokers (<20 pack-years), moderate smokers (20-40 pack-years), and heavy smokers (> 40 pack-years). Results The three BP groups had similar age and metabolic parameters (body mass index, fasting blood glucose and LDL-C). Figure shows PWV, AIx and carotid IMT by smoking exposure, stratified by BP level. The lowest PWV level was observed in never smokers with normal BP; whereas heavy smokers with hypertension exhibited the highest PWV. Also of note, heavy smokers with normal BP exhibited comparable PWV to light and never smokers with hypertension. Furthermore, in smokers with more than 20 pack-years tobacco exposure, PWV was higher among patients with high normal BP compared to subjects with normal BP (all P<0.01). In contrast to the monotonic increases in PWV and AIx by BP and pack-years smoking history, carotid IMT was generally similar among BP groups on the basis of cumulative exposure category. This finding may indicate a plateau in subclinical atherosclerotic burden over cumulative tobacco exposure for all BP categories. Conclusion Tobacco cumulative exposure adversely modify the effect of BP on arterial stiffness. Given that most adults who smoke start before the age 18 years, efforts to promote smoking cessation should continue to target younger adults with high BP.BP, tobacco exposure-vascular changes

Unseen threat: how subclinical atherosclerosis increases mortality risk in patients with type 1 diabetes

BackgroundCardiovascular disease (CVD), particularly ischemic heart disease, remains the leading cause of death and morbidity in patients with type 1 diabetes. Detecting subclinical atherosclerosis could enhance cardiovascular risk stratification and enable individualised therapies. The aim of this study is to investigate the prevalence and predictors of subclinical atherosclerosis in patients with type 1 diabetes without overt cardiovascular disease (CVD) and to assess its impact on patient survival over a follow-up period of at least 5 years.MethodsThis observational study included 507 patients treated at the Diabetes Unit of the Hospital of Girona Doctor Josep Trueta between 2015 and 2023. The inclusion criteria for patients were as follows: those aged 18 and older with diabetes for a minimum of 10 years or those aged 40 and older with a diabetes for at least 5 years. Subclinical atherosclerosis was identified via ultrasound imaging of the carotid and femoral arteries. Clinical and biochemical evaluations were also conducted. Major cardiovascular events (MACE) and deaths from other causes were monitored, and survival analysis was performed using Kaplan‒Meier methods.ResultsSubclinical atherosclerosis was detected in 218 patients (43%). Multivariate analysis revealed that the male sex, diabetic nephropathy, tobacco exposure, higher HbA1c levels, older age, and longer diabetes duration were significant predictors. During a mean follow-up of 70.64 ± 27.08 months, 19 patients experienced MACE, and 13 died from any cause. The probability of MACE or death was greater in patients with subclinical atherosclerosis, with a hazard ratio (HR) of 25.1 (95% CI 5.81–108, p < 0.001) for MACE and an odds ratio (OR) of 7.57 (95% CI 1.97–53.9, p = 0.004) for death.ConclusionSubclinical atherosclerosis is independently associated with increased overall mortality and MACE in patients with type 1 diabetes. Identifying clinical predictors can improve risk stratification and personalised therapeutic strategies to prevent MACEs in this high-risk population.Graphical

Cardiovascular Risk in Patients with Ankylosing Spondylitis.

Objectives: Ankylosing spondylitis (AS) is an autoinflammatory, chronic disease. Patients with AS are at increased risk of cardiovascular disease (CVD). The link between AS and subclinical atherosclerosis is multifactorial and still not completely understood. The aim of this study was to examine the potential associations between carotid intima-media thickness (cIMT) and different cardiometabolic biomarkers in individuals with AS. Methods: A total of 96 patients with AS were prospectively included. cIMT was measured via ultrasonography. Multiple linear regression analysis was used to find the best predictors of cIMT values. Principal component analysis (PCA) was implemented to extract factors that were further tested via binary logistic regression analysis in relation to cIMT. Results: Waist circumference (WC), low-density lipoprotein cholesterol (LDL-c), and the BASDAI score were independently correlated with cIMT in AS patients (p = 0.037, p = 0.060, and p = 0.048, respectively; adjusted R2 = 0.113). PCA extracted four panels of biomarkers, i.e., "haematology-lipid-related factor" (i.e., ferritin, haemoglobin, HDL-c, and triglycerides), "proinflammatory-prothrombotic-related factor" (i.e., platelets, neutrophils, and C-reactive protein), "LDL-c-vitamin-related factor" (i.e., vitamins D and B12, and LDL-c), and "age-glucometabolic-related factor" (i.e., age and HbA1c), in relation to higher cIMT in patients with AS. Among these four clusters, "age-glucometabolic-related factor" was an independent predictor of increased cIMT (p < 0.001). Conclusions: In addition to traditional cardiometabolic risk factors, WC and LDL-c, the disease activity score (BASDAI) is independently related to subclinical atherosclerosis in AS patients. The joint involvement of heterogeneous cardiometabolic risk factors may reflect different pathophysiological processes of subclinical atherosclerosis in patients with AS.

Does Serum 25-OH Vitamin D Affect the Development of Subclinical Atherosclerosis in Patients with Primary Hypertension?

Does Serum 25-OH Vitamin D Affect the Development of Subclinical Atherosclerosis in Patients with Primary Hypertension?

VEGF Polymorphisms (VEGF-936 C/T, VEGF-634 G/C and VEGF-2578 C/A) and Cardiovascular Implications in Long COVID Patients.

The COVID-19 pandemic has raised awareness of the virus's long-term non-pulmonary consequences. This study examined the relationship between genetic polymorphisms of VEGF and cardiac dysfunction and subclinical atherosclerosis in patients recovering from COVID-19. This study included 67 patients previously diagnosed with COVID-19. VEGF-936C/T, VEGF-634G/C, and VEGF-2578C/A statuses were determined. Conventional echocardiography and arterial parameters assessments were performed at inclusion and at six months after the first assessment. For VEGF-936C/T, dominant and over-dominant models showed a significant increase in ejection fraction at six months after COVID (p = 0.044 and 0.048) and was also a predictive independent factor for the augmentation index (β = 3.07; p = 0.024). The dominant model showed a rise in RV-RA gradient (3.702 mmHg) (p = 0.028 95% CI: 0.040-7.363), with the over-dominant model indicating a greater difference (4.254 mmHg) (p = 0.025 95% CI: 0.624-7.884). The findings for VEGF-634G/C were not statistically significant, except for a difference in TAPSE during initial evaluation, using the codominant model. For VEGF-2578C/A, a difference in ventricular filling pressure (E/E'ratio) was best described under the recessive model. Our research suggests that the VEG-936C/T genotype may impact the baseline level and subsequent changes in cardiac function and subclinical atherosclerosis. These findings offer valuable insights into the complex correlation between genetic polymorphisms and cardiovascular disfunction in long COVID patients.

Subclinical Atherosclerosis and Endothelial Dysfunction in Cases of Systemic Lupus Erythematosus: A Hospital-Based Case-Control Study.

Background Women are more likely to be affected with systemic lupus erythematosus (SLE), a chronic multisystem inflammatory autoimmune illness. It is well established that SLE increases the risk of cardiovascular (CV) events. This study aimed to determine the prevalence of endothelial dysfunction and subclinical atherosclerosis in patients with SLE. If these conditions are identified early, suitable preventative measures may be advocated to lessen the burden of future CV events. Aim This study aims to calculate the frequency of endothelial dysfunction and subclinical atherosclerosis in SLE patients using the flow-mediated dilatation (FMD) of the brachial artery and carotid intima-media thickness (c-IMT). Results There were 50 confirmed cases of SLE. Compared to healthy controls, SLE patients' c-IMT readings were higher, suggesting subclinical atherosclerosis. Thirty-three patients with c-IMT values >0.06 (p<0.00269) out of 50 SLE cases were found to have a high prevalence of subclinical atherosclerosis. Five SLE patients showed FMDs of less than 4.5% (p<0.021) compared to healthy controls, indicating preclinical atherosclerosis with endothelial dysfunction. It was discovered that endothelial dysfunction exhibited a positive linear connection with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) when contrasted with traditional inflammatory indicators such as ESRand CRP. Conclusion Patients with SLE face a higher risk of CV events and mortality compared to those without the condition. They are also more prone to developing endothelial dysfunction and subclinical atherosclerosis. Detecting these issues early can help in implementing primary and secondary prevention strategies effectively.

Apnea-Specific Pulse-Rate Response is Associated With Early Subclinical Atherosclerosis in Obstructive Sleep Apnea

IntroductionIn patients with obstructive sleep apnea (OSA), novel metrics such as hypoxic burden (HB) and sleep apnea-specific pulse-rate response (ΔHR) may better correlate with cardiovascular diseases (CVD) than the apnea–hypopnea index (AHI). This manuscript aims to assess the correlation between ΔHR and HB with subclinical atherosclerosis in patients with OSA, testing the hypothesis that elevated ΔHR and HB are associated with subclinical atherosclerosis development. MethodsIn a prospective study, individuals aged 20–65 years with suspected OSA without known comorbidities were consecutively recruited and defined as OSA (AHI≥5events/h) or healthy controls. Using bilateral carotid ultrasonography, common carotid intima-media thickness (CIMT) was assessed and the identification of at least one atheromatous plaque defined the presence of subclinical atherosclerosis. ΔHR, and HB were derived from pulse-oximetry. ResultsWe studied 296 patients of 45±10 years old, of whom 28% were women, and a BMI of 30.3±5.3kg/m2. Overall, 245 had OSA and 51 were healthy controls. After controlling for confounding variables higher ΔHR but not HB, was associated with higher CIMT (p=0.006) and higher time spent with oxygen saturation below 90% (T90) was associated with an increase in carotid atheroma plaques (p=0.032). When stratifying OSA based on HB tertiles, we observed that within tertile 2 of HB, an increase in ΔHR was associated with larger CIMT (p=0.017). ConclusionA higher ΔHR is associated with an increase in CIMT among adult patients with OSA. This study suggests that ΔHR could be a biomarker of risk for CVD in patients with OSA.

Evaluation of Subclinical Atherosclerosis in Patients with Psoriatic Arthritis

Background/Aims: Psoriatic arthritis with peripheral and axial involvement; It is a heterogeneous disease that can cause enthesitis, dactylitis, and nail and skin involvement. The persistence of inflammation in psoriasis leads to comorbidities such as psoriatic arthritis, cardiovascular disease, and metabolic syndrome. Our study aimed to identify subclinical atherosclerosis in psoriatic arthritis patients without a known risk factor and to prevent possible morbidity and mortality in patients. Methods: Thirty-three patients with psoriatic arthritis and twenty-five healthy control groups were included in our study. Diabetes mellitus, hypertension, coronary artery disease, diagnosis of hyperlipidemia, body mass index above 30, and smoking were determined as exclusion criteria. The age, gender, duration of the disease, medical treatment used for the disease, high-density lipoprotein, low-density lipoprotein, triglyceride, and total cholesterol values, monocyte-lymphocyte ratio, carotid intima-media thickness measurement results obtained by carotid doppler ultrasonography imaging were recorded. Results: A comparison was made between the study and control groups in terms of age, triglyceride, high-density lipoprotein, low-density lipoprotein, and monocyte-lymphocyte ratio, and no statistically significant difference was observed. Monocyte and lymphocyte levels were significantly higher in the study group (p&amp;lt;0.05). Carotid intima-media thickness was statistically higher in the study group and this difference was statistically significant (p&amp;lt;0.05). Conclusions: Patients with psoriatic arthritis have an increased risk of atherosclerosis compared to the healthy population without any risk factors. This awareness will be useful in the follow-up of patients and in taking precautions against morbidities that may develop.

Increased epicardial adipose tissue thickness as a sign of subclinical atherosclerosis in patients with rheumatoid arthritis and ıts relationship with disease activity ındices

Epicardial adipose tissue is a novel cardiometabolic risk factor and indicator of subclinical atherosclerosis. We aimed to evaluate the epicardial adipose tissue thickness in rheumatoid arthritis (RA) patients and its association with disease activity scores. A total of 81 rheumatoid arthritis patients and 70 age- and sex-matched healthy individuals were recruited for this cross-sectional study. Epicardial adipose tissue thickness (EATT) was measured by transthoracic two-dimensional echocardiography. Tender and swollen joint counts were recorded at the time of inclusion. The laboratory tests included erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor, anti-citrullinated protein antibodies, and serum lipid levels. Disease activity was calculated based on Disease Activity Scores for 28 joints (DAS-28) ESR and CRP, the Simple Disease Activity Index (SDAI), and the Clinical Disease Activity Index (CDAI). Epicardial adipose tissue thickness was significantly higher in the RA patients compared to the healthy controls (p < 0.001). We found statistically significant correlations of EATT with all disease activity indices (p < 0.001) and CRP (p = 0.002). According to a cut-off value of 6.4 mm determined for epicardial adipose tissue thickness, the RA patients with thickness ≥ 6.4 mm had higher disease activity scores and CRP levels. In the multivariable regression analysis, only SDAI score was found as an independent risk factor for increased EATT (OR, (95%CI), 13.70 (3.88–48.43), p < 0.001). Epicardial adipose tissue thickness measurement by echocardiography is a reliable method for assessing subclinical atherosclerosis in rheumatoid arthritis patients, and a higher disease activity score is an independent risk factor for coronary artery disease.

Predictors of subclinical atherosclerosis in patients with rheumatoid arthritis

Abstract Background: Rheumatoid arthritis (RA) is a chronic inflammatory disorder involving the joints along with various other extra-articular manifestations. Mortality due to coronary artery disease is higher in patients with RA when compared to the general population. Hence, this study is undertaken to assess the predictors of sub-clinical atherosclerosis in patients with RA, so that early prompt management can prevent cardiovascular complications. Methods: A case–control study with 42 patients of RA and 42 healthy age- and sex-matched controls was undertaken. Relevant investigations were done. Disease Activity Score (DAS)-28 was calculated. Carotid artery doppler was performed on both sides to examine the common carotid artery. Results: The mean carotid intima–media thickness (CIMT) (mm) was significantly higher in RA patients compared to controls on the right side (0.57 ± 0.11 Vs 0.40 ± 0.03; P &lt; 0.001) as well as left side (0.56 ± 0.11 Vs 0.39 ± 0.06; P &lt; 0.001). Only age (P = 0.006) and DAS-28 (P = 0.002) showed a positive correlation with CIMT. Conclusions: CIMT can be used as a marker for the detection of subclinical atherosclerosis and the risk of atherosclerosis increases with the increasing age and increasing disease severity.

Diagnostic and prognostic role of serum interleukin-6 and carotid ultrasonography to detect subclinical atherosclerosis in patients with RA and ANCA-associated vasculitis.

ANCA-associated vasculitis (AAV) can affect multiple organs with severe life-threatening manifestations. Disease monitoring is difficult due to a lack of defined biomarkers. We aimed to assess the diagnostic role of serum interleukin-6 and vascular ultrasonography in AAV and subclinical atherosclerosis. The study included 20 AAV patients and two control groups of 34 patients with rheumatoid arthritis (RA) and 35 healthy controls. The levels of Il-6, carotid intima-media thickness test (CIMT), atherosclerotic plaque, and degree of stenosis were investigated. A GRACE-risk score was calculated for AAV and RA patients. The AAV patients had elevated levels of IL-6 (115 ± 23.96) compared to the RA patients (91.25 ± 42.63) and the healthy controls (15.65 ± 3.30), p < 0.001. IL-6 showed a diagnostic accuracy of 73% in distinguishing AAV from RA patients (AUC = 0.730; 95% CI 0.591 to 0834). In the AAV group, CIMT was 1.09, above the upper reference value of 0.90, p < 0.001. The AAV patients had a higher median GRACE risk score, and 60% of them had a high risk of cardiovascular events as compared to 35% of the RA patients. Sonography of extracranial vessels and serum levels of IL-6 can be used in daily clinical practice to diagnose and monitor patients with AAV.

Impact des antiviraux à action directe sur l'athérosclérose subclinique chez les patients atteints d’une hépatite C chronique

The impact of direct antiviral drugs (DAAs) on extrahepatic manifestations in chronic hepatitis C (CHC) has been poorly studied. To assess the prevalence of subclinical atherosclerosis in patients with CHC and the impact of DAAs on atherosclerotic lesions. Methods A 5-year prospective evaluative study, including patients followed for CHC at hepato-gastroenterology department. The subclinical atherosclerosis was assessed by ultrasound measurement of carotid intima-media thickness (IMTc) and the highest IMTc measurements from the left and right side defined the IMTc maximum (IMTc max). IMTc>75th percentile (IMTc75) define subclinical atherosclerosis with high cardiovascular risk. Patients were evaluated before (T0) and one year after DAAs therapy achievement (T1). At time T0, forty patients (median age: 55 y.; sex ratio M / F = 0.48), were included. Average value of IMTc max was 0.68 ± 0.16 mm. Subclinical atherosclerosis was noted in 82.5 %. At time T1, 28 patients were evaluated, all of whom completed sustained virological response (SVR). Compared to time T0, there was a significant increase in cholesterol (p = 0.001) and triglyceride (p = 0.009) levels. IMTc max was significantly higher at time T1 compared to T0 (0.75 Vs 0.67 mm, p = 0.04). Prevalence of IMTc75 was 82.1% at time T0 and 75% at time T1 (p=0.5). SVR, in CHC patients treated with DAA, was associated with worsening of carotid atherosclerotic lesions.

Monocyte-to-High-Density Lipoprotein Ratio Is Associated with Systemic Inflammation, Insulin Resistance, and Coronary Subclinical Atherosclerosis in Psoriasis: Results from 2 Observational Cohorts

Systemic inflammation or insulin resistance drive atherosclerosis. However, they are difficult to capture for assessing cardiovascular risk in clinical settings. The monocyte-to-HDL ratio (MHR) is an accessible biomarker that integrates inflammatory and metabolic information and which has been associated with poorer cardiovascular outcomes. Our aim was to evaluate the association of MHR with the presence of subclinical atherosclerosis in patients with psoriasis. The study involved a European and an American cohort including 405 patients with the disease. Subclinical atherosclerosis was assessed by coronary computed tomography angiography. First, MHR correlated with insulin resistance via HOMA-IR, with high sensitivity C-reactive protein and with 18F-FDG uptake in spleen, liver and bone marrow by PET/CT. MHR associated with both the presence of coronary plaques greater than 50% of the artery lumen and non-calcified coronary burden (NCB), beyond traditional cardiovascular risk factors (p<0.05). In an NCB prediction model accounting for cardiovascular risk factors, statins and biologic treatment, MHR added value (AUC base model 0.72 vs AUC base model plus MHR 0.76, p=0.04) within the American cohort. These results suggests that MHR may detect psoriasis patients who have subclinical burden of cardiovascular disease and warrant more aggressive measures to reduce lifetime adverse cardiovascular outcomes.

Dynamic natural components and morphological changes in nonculprit subclinical atherosclerosis in patients with acute coronary syndrome and mild chronic kidney disease at the 1-year follow-up and clinical significance at the 5-year follow-up.

The natural outcome of coronary plaque in acute coronary syndrome (ACS) patients with chronic kidney disease (CKD) is unique, which can be analyzed quantitatively by optical flow ratio (OFR) software. A total of 184 ACS patients with at least one nonculprit subclinical atherosclerosis (NSA) detected by optical coherence tomography (OCT) at baseline and 1-year follow-up were divided into non-CKD group (n = 106, estimated glomerular filtration rate (eGFR)> 90 mL/(min×1.73 m2)) and mild CKD group (n = 78, 60≤eGFR<90 mL/(min×1.73 m2)). Changes of normalized total atheroma volume (TAVn) of NSA was the primary endpoint at the 1-year follow-up. Patients with mild CKD showed more TAVn progression of NSA than non-CKD (p = 0.019) from baseline to the 1-year follow-up, which was mainly due to an increase in calcium TAVn (p<0.001). The morphological change in the maximal calcification thickness (p = 0.026) was higher and the change in the distance from the calcified surface to the contralateral coronary media membrane (ΔC-to-M) at the maximal cross-sectional calcium area was lower (p<0.001) in mild CKD group than in non-CKD group. Mild CKD had more NSA related MACEs at the 5-year follow-up than non-CKD (30.8% vs. 5.8%, p = 0.045). Mild CKD patients had more plaque progression of NSA which showed the increase of calcium component with more protrusion into the lumen morphologically at the 1-year follow-up and a higher corresponding incidence of NSA-related MACEs at the 5-year follow-up.

Comparison of Carotid Ultrasound Parameters in Patients with Rheumatoid Arthritis and Control Subjects: A Cross-sectional Study

Introduction: Rheumatoid Arthritis (RA) is considered one of the risk factors for Cardiovascular Disease (CVD). Carotid ultrasound is used to assess the extent of subclinical atherosclerosis in patients with RA. Very few studies have evaluated all carotid ultrasound findings, such as Carotid Intima-media Thickness (CIMT), carotid diameters like Luminal Diameter (LD) and Interadventitial Diameter (IAD), and plaque characteristics in patients with RA. Aim: To assess and compare the various carotid parameters in RA patients with controls and also to evaluate their association with age and duration of onset of the disease. Materials and Methods: A single-centre cross-sectional study was conducted at the Department of Radiology, GCS Medical College and Hospital, Ahmedabad, Gujarat, India, involving 40 patients with RA (Group-RA) and 40 controls (Group-C). Patients were further divided into three age subgroups. Carotid ultrasound parameters like CIMT, LD, IAD, and plaque were evaluated in both groups. Continuous variables were analysed using the t-test, and categorical data were analysed using the Chi-squared test. A p-value of &lt; 0.05 was considered statistically significant. Results: Age- and sex-matched controls were included with 28 females and 12 males in both the study groups. The mean LD and IAD were significantly higher in the RA group than in controls (Mean LD- 5.88±0.97 mm vs 5.26±1.08 mm with p=0.009; Mean IAD- 6.85±0.89 mm vs 6.30±0.87 mm with p=0.006). The mean CIMT was higher in the RA group but not statistically significant (0.57±0.13 mm vs 0.54±0.12 mm with p=0.256). Further subgroup analysis showed that all carotid parameters were statistically significant in the 31-60 years age group as compared to 18-30 years and 61-80 years subgroups. The effect of the duration of the disease (&gt;5 years) on the carotid parameters was also significantly higher in the 30-60 age group (p&lt;0.001). Conclusion: The present study showed that various carotid ultrasound parameters can be used as a screening tool in the follow-up of RA patients to detect early changes in atherosclerosis, with LD and IAD having superior predictive capability. The study further showed that carotid ultrasound parameters have a better predictive value in the 31-60 years age group.

Is Sortilin an Indicator of Subclinical Atherosclerosis in Patients with Psoriasis?

Association of the Complement System with Subclinical Atherosclerosis in Psoriasis: Findings from an Observational Cohort Study

Psoriasis is a chronic and inflammatory disease that affects the skin and joints and is associated with multiple comorbidities and cardiovascular risk factors. Consequently, patients with psoriasis have an increased risk of cardiovascular diseases such as atherosclerosis, a chronic pathology that shares common inflammatory and immune-response mechanisms with psoriasis, including vascular inflammation and complement activation. To better understand the relationship between atherosclerosis and psoriasis, a proteomics study followed by a bioinformatics analysis was carried out, with a subsequent validation step using ELISA and western blotting. When the plasma from patients with psoriasis alone was compared with that from patients with psoriasis and atherosclerosis, 31 proteins of interest related to the complement system and oxygen transport were identified. After the validation phase, 11 proteins appeared to define the presence of subclinical atherosclerosis in patients with psoriasis, indicating the importance of complement cascades in the development of atherosclerotic plaques in individuals with psoriasis. These results are a step forward in understanding the pathological pathways implicated in the cardiovascular risk associated with this population, which may represent an interesting starting point for developing predictive tools that improve the follow-up of these patients and design more effective therapies.

Risk of subclinical atherosclerosis in primary Sjogren's syndrome: A systematic review and meta-analysis

BackgroundCurrently, the guidelines for prevention and management of atherosclerosis in patients with Sjogren's syndrome (SS) do not differentiate from those concerning the general population. ObjectivesThe present systematic review aimed to summarize evidence from primary studies assessing the risk of subclinical atherosclerosis in patients with primary SS (pSS). Methods and resultsLiterature was searched until June 2023. Eligible records were randomized controlled trials and observational studies comparing subclinical atherosclerosis markers between pSS patients and healthy controls. DerSimonian-Laird random effects models were used to calculate overall effect estimates. Totally, 19 observational studies comprising 1625 participants were included. Compared to healthy controls, pSS patients had significantly higher values of carotid-femoral intima-media thickness (cfIMT) (MD= 0.07 mm; 95 % CI= [0.04, 0.11]; p <0.001) and were more frequently diagnosed with atherosclerotic plaques (OR= 1.9; 95 % CI= [1.32, 2.74]; p <0.001). Moreover, pSS patients showed a decreased flow and nitrate-mediated dilation (MD = -2.48 %; 95 % CI= [-4.57, -0.39]; p = 0.02, MD= -2.11 %; 95 % CI= [-3.22, -1.01]; p <0.001, respectively). Similar results were observed for the pulse-wave velocity (MD= 0.7 m/s; 95 % CI= [0.36, 1.05]; p <0.001) and the ankle-brachial index (OR= 5.78; 95 % CI= [2.23, 14.99]; p = 0.003). Based on meta-regression analyses, only the disease duration and erythrocyte sedimentation rate were positively and significantly associated with higher cfIMT values. ConclusionPatients with pSS have an increased risk of subclinical atherosclerosis compared to healthy population and thus possibly require early and disease-specific intervention. Further research is warranted for more accurate cardiovascular risk management in SS.
