Int J Mol Sci 2024; 25:12425.

Abstract
In recent years, many atherogenesis researchers have focused on the role of inflammatory cytokines in the development of cardiovascular disease (CVD). Interleukin-6 (IL-6) cytokine is independently associated with higher CVD risk in patients with rheumatoid arthritis (RA). The effect of IL-6 inhibitors on the cardiovascular system in RA patients remains poorly understood, especially with its long-term use. This study investigates the effect of therapy with IL-6 receptor blocker tocilizumab (TCZ) on the dynamics of cardiovascular risk (CVR), modifiable risk factors (RFs), carotid artery (CA) structural changes, and the incidence of cardiovascular complications (CVCs) in RA patients during a 265-week follow-up period. Forty-five patients with active RA (DAS28-ESR 6.2 (5.5;6.8) with ineffectiveness and/or intolerance to disease-modifying antirheumatic drugs (DMARDs) were included in this study. During long-term therapy with TCZ in RA patients, no increase in CVR and no significant structural changes in CA were observed. No significant changes in the blood lipid spectrum were observed in patients without statin therapy. In the group of patients receiving statins, there was a 43% increase in high-density lipoprotein cholesterol (HDL-C), a 15% reduction in total cholesterol levels, and a 56% decrease in the atherogenicity index (p < 0.01 in all cases). Associations were found between ∆ total cholesterol and ∆ C-reactive protein (CRP) (R = 0.36, p = 0.04), ∆ low-density lipoprotein cholesterol (LDL-C), and ∆-CRP (R = 0.42, p = 0.03) in RA patients receiving statins. Initially, the thickness of the intima-media complex of carotid arteries (cIMT) positively moderately correlated with age (R = 0.7; p < 0.01), BMI (R = 0.37; p < 0.01), and systolic blood pressure (R = 0.64; p < 0.01); however, it weakly correlated with the lipid spectrum parameters: total cholesterol (R = 0.29; p < 0.01) and LDL-C (R = 0.33; p < 0.01). No new associations of cIMT by the end of the follow-up period, as well as the relationship of cIMT value with RA activity and therapy, were revealed. Patients with carotid ASPs showed an oppositely directed relationship between total cholesterol and sVCAM-1 at baseline (R = -0.25, p = 0.01) and at the end of this study (R = 0.29, p < 0.01). The incidence of cardiovascular events was 0.53 per 100 patient-years during the 265-week period of TCZ therapy.

Am J Transl Res 2024; 16:4564-4576. [PMID: 39398582 PMCID: PMC11470337 DOI: 10.62347/nqfj9713] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Accepted: 08/04/2024] [Indexed: 10/15/2024]
Abstract
BACKGROUND The low diagnosis and treatment rates of familial hypercholesterolemia (FH) have become a global issue. This study aims to explore the correlation between early-onset coronary artery disease (CAD) and FH in the Hakka population in Meizhou, Guangdong. METHODS Clinical data of Hakka patients with early-onset CAD, admitted to the Meizhou People's Hospital from January 2023 to January 2024 were retrospectively analyzed. The patients were categorized into an FH group and a non-FH group. Biochemical indicators, lipid levels, echocardiographic parameters, clinical phenotypes, and genetic typing of early-onset CAD patients in the Hakka population were analyzed for their correlation with FH. RESULTS A total of 167 Hakka patients with early-onset CAD were included, among whom 22 patients had FH. The FH group showed lower triglyceride (TG) level [1.785 (1.40, 2.10) vs. 2.090 (1.80, 2.30), P = 0.002] and higher levels of total cholesterol (TC) [6.635 (5.60, 7.10) vs. 4.830 (4.00, 5.40), P<0.001], low-density lipoprotein cholesterol (LDL-C) [4.440 (3.90, 5.20) vs. 2.820 (2.40, 3.30), P<0.001], and apolipoprotein B (Apo B) [1.600 (1.30, 1.80) vs. 0.910 (0.70, 1.10), P<0.001]. FH was correlated with TG, TC, LDL-C and Apo B levels (r1 = -0.235; r2 = 0.441; r3 = 0.483; r4 = 0.538). TG is a risk factor while TC, LDL-C and Apo B are protective factors for FH. CONCLUSION The incidence of FH is relatively high among early-onset CAD patients in the Hakka population in Meizhou. TG, TC, LDL-C, and Apo B levels are valuable in aiding clinical differential diagnosis of CAD patients with FH.

Abstract
Apple (Malus domestica) is the third most produced fruit worldwide. It is a well-known source of bioactive compounds mainly represented by hydroxycinnamic acids, flavan-3-ols, dihydrochalcones, dehydroascorbic acid, carotenoids, chlorogenic acid, epicatechin, and phloridzin. Due to the lack of a recent evaluation of the clinical trials associated with apple consumption, this review investigated the effects of this fruit on metabolic conditions related to inflammation and oxidative stress and reviewed the applications of apple waste on food products. Thirty-three studies showed that apples or its derivatives exhibit anti-inflammatory and antioxidant actions, improve blood pressure, body fat, insulin resistance, dyslipidemia, and reduce cardiovascular risks. Apples have a great economic impact due to its several applications in the food industry and as a food supplement since it has impressive nutritional value. Dietary fiber from the fruit pomace can be used as a substitute for fat in food products or as an improver of fiber content in meat products. It can also be used in bakery and confectionary products or be fermented to produce alcohol. Pomace phytocompounds can also be isolated and applied as antioxidants in food products. The potential for the use of apples and by-products in the food industry can reduce environmental damage.

Abstract
OBJECTIVE Hypertension is one of the most important causes of cardiovascular disease. It has been found that professional drivers are at high risk of hypertension. This study has been performed to determine the prevalence of hypertension and its associated factors among professional drivers in Shahroud. METHODS AND RESULTS In this study, the prevalence of hypertension was determined according to the definition by the American Heart Association among 1461 professional drivers participating in the first cross-sectional phase of Shahroud drivers' prospective cohort study. The prevalence of elevated blood pressure and hypertension was examined based on the initial age, and gender presented, along with the factors affecting this disease based on multinomial logistic regression. The prevalence of elevated blood pressure, stage 1 and 2 hypertension was 46.9%, 6%, and 1.3%, respectively. In the multivariate multinomial logistic regression model, having diabetes, Body Mass Index ≥25, and driving years was associated with an increased chance of developing elevated blood pressure and hypertension. CONCLUSIONS Attention should be paid to high prevalence of elevated blood pressure and hypertension among professional drivers in Iran as a health priority for drivers. Plans should be made to reduce it as well as to prevent its complications.

Abstract
Introduction Interleukins (ILs) can act as a predictive indicator of Premature Coronary Artery Disease (pCAD) and may be useful in screening of high-risk patients. However, there is no consensus on the relationship of serum levels of ILs and pCAD, yet. As a result, this study has been conducted in order to review the literature on the relationship between serum levels of different ILs and pCAD. Methods Medline, Scopus, Embase, and Web of Science databases were searched until December 7th 2020. Two reviewers independently screened and summarized eligible articles. A meta-analysis was performed to assess the relationship of ILs and pCAD. Results 12 case-control articles were included. IL-6 plasma changes do happen in pCAD patients with a standardized mean difference (SMD) of 0.51 (95% CI: 0.12-0.90; p=0.010) compared with the control group. This difference was also observed when evaluating the plasma levels of IL-1 and IL-17, with an SMD of 1.42 (95% CI: 1.11-1.73; p<0.001) and 0.59 (95% CI: 0.14-1.04; p=0.011), respectively. Meanwhile, no significant difference existed in plasma levels of IL-10 (SMD=0.26; 95% CI: -0.17-0.70; p=0.236), and IL-18 (SMD=1.44; 95% CI: -0.19-3.07; p=0.083) between pCAD patients and those in the control group. Conclusion Low level of evidence showed that there may be a significant relationship between increased plasma levels of ILs and the occurrence of pCAD. As a result, prospective cohort studies with serial assessments of serum ILs during follow up period, focusing on controlling classical risk factors of pCAD and increase in level of ILs, should be conducted.

Abstract
Oral lichen planus (OLP) is a complex chronic inflammatory disorder in which autocytotoxic CD8+ T cells, locally present in the affected tissue, induce basal keratinocyte apoptosis, through the release of several cytokines, such as interleukin-6 (IL-6). IL-6 is a proinflammatory cytokine that is related to alterations in lipid metabolism in psoriasis patients. Impaired lipid metabolism together with high serum levels of triglycerides have been found in association with OLP. However, the correlation between serum levels of IL-6 and dyslipidemia has not yet been studied in this disorder. The present study aimed to demonstrate the association between OLP, systemic inflammation through increased release of inflammation mediators such as IL-6 and alteration of lipid metabolism, in order to support the concept of OLP as a marker of systemic inflammation and a potential risk factor of cardiovascular morbidities. For this purpose, we designed a case-control study using a cohort of 18 patients with different clinical forms of OLP compared with 18 control group patients with other oral conditions, to identify a potential correlation between serum levels of IL-6 and serum lipid levels. High plasma serum levels of IL-6 were found to be correlated with cholesterol, high density lipoprotein cholesterol and triglyceride serum levels in the patients with OLP. There was a significant association between erosive and atrophic clinical forms of OLP and the pathological serum values of IL-6 and triglycerides, respectively, making these two parameters good predictive factors of the clinical form of OLP. Further studies of other biomarkers of systemic inflammation using larger cohorts of OLP patients are necessary in order to consider LP as a marker of systemic inflammation and to support the screening of these patients for lipid metabolism changes and treatment with specific antagonists in order to prevent cardiovascular events.

Abstract
Aim. To evaluate the cardiovascular risk (CVR) and analyze its relationship with detection of early carotid artery atherosclerotic lesion in patients with rheumatoid arthritis (RA).
Materials and methods. One hundred and nine RA patients aged 45 to 60 without established cardiovascular diseases (CVD) were included in the study. The median age was 52 [48; 54] years, duration of RA was 120 [36; 204] months, DAS28 was 4.7 [3.5; 5.6] points. CVD risk was calculated with mSCORE, Reynolds Risk Score (RRS), ASSIGN, QRISK3, ERS-RA scales and Carotid Artery Doppler Ultrasound Exam was performed for all patients.
Results. High risk was found in 5, 5, 14, 6, and 38% of patients according to mSCORE, RRS, ASSIGN, QRISK3, ERS-RA scales, respectively. Atherosclerotic plaques of carotid arteries were found in 30% of patients. It was found that carotid intima-media thickness is correlated to all CVR calculators, age, systolic and diastolic blood pressure, cholesterol, erythrocyte sedimentation rate, interleukin-6 levels. The sensitivity and specificity of the CVR algorithms in prognostication of atherosclerotic carotid artery lesions were 73 and 67% for mSCORE, 64 and 63% for RRS, 64 and 56% for ASSIGN, 73 and 49% for QRISK3, respectively, p0.05 in all cases, 67 and 50% for ERS-RA, p=0.06.
Conclusion. RRS, mSCORE, ASSIGN, QRISK3 calculators equally predict atherosclerotic carotid artery damage in RA patients. The optimal ratio of specificity and sensitivity is shown for the mSCORE scale. Stratification of CVR in RA patients should include assessment of the carotid intima-media thickness. To identify CVR in RA patients, the most informative methods are mSCORE calculation and carotid intima-media thickness determination.

Abstract
Background: Various cell types undergo activation and stress during atherosclerosis resulting in the development of acute myocardial infarction (AMI) in coronary artery disease (CAD). Major histocompatibility complex class I related chain A and B (MICA/B) can be expressed on the surface of activated and stressed cells and released into blood circulation in several forms including microparticles (MICA/B+ MPs) from various cell types. We aimed to investigate the association of these MICA/B+ MPs with the presence of AMI. Fifty-one AMI and 46 age-matched control subjects were recruited. Methods: Levels of MICA/B+ MPs derived from various parent cells including endothelial cells, platelets, monocytes, neutrophils, and T lymphocytes were determined by flow cytometry. Results: The levels and proportion of MICA/B+ MPs from all types of cell origin were significantly increased in AMI patients compared to those of the controls. A multivariate regression model showed an independent association between MICA/B+ MPs and AMI (OR = 11.6; 95% CI = 2.8, 47.3). Interestingly, based on the disease severity, we found that the levels of MICA/B+ MPs were significantly elevated in the ST-segment elevation myocardial infarction (STEMI) compared to the non-STEMI (NSTEMI) patients. Moreover, an independent association of MICA/B+ MPs with the occurrence of STEMI was also demonstrated (OR = 4.1; 95% CI = 1.5, 16.7). Conclusions: These results suggest that MICA/B+ MPs are associated with AMI and disease severity. They may act as mediators contributing to the pathological process of AMI. Alternatively, they are the results of various cell activations contributing to AMI.
