Abstract
BACKGROUND Despite the widespread use of classical cholesterol-lowering drugs to mitigate the adverse impacts of dyslipidaemia on atherosclerosis, many patients still face a substantial residual risk of developing atherosclerotic cardiovascular disease (CVD). This risk is partially attributed to non-traditional pathophysiological pathways. Latest evidence suggests that sodium glucose co-transporter-2 (SGLT2) inhibitors are beneficial for patients suffering from type 2 diabetes mellitus (T2DM) or established CVD by reducing morbidity and mortality. However, the underlying mechanisms of this benefit have not been clearly elucidated. It has been hypothesized that one possible mechanism could be the attenuation of subclinical atherosclerosis (SA) progression. AIM The objective of this narrative review is to examine the present evidence concerning the impact of SGLT2 inhibitors on markers of SA. RESULTS The current evidence on the efficacy of SGLT2 on SA, endothelial function and arterial stiffness remains controversial. Findings from observational and randomized studies are quite heterogeneous; however, they converge that the antiatherosclerotic activity of SGLT2 inhibitors is not strong enough to be widely used for prevention of atherosclerosis progression in patients with or without T2DM. CONCLUSIONS Further research is needed to investigate the underlying mechanisms and the possible beneficial impact of SGLT2i on primary and secondary CVD prevention through attenuation of premature atherosclerosis progression.

Abstract
Despite its significant impact on mortality, tuberculosis (TB)-diabetes mellitus (DM) co-prevalence has not been well-elucidated for the cause of death. We investigated the impact of DM on TB-related and non-TB-related deaths in patients with TB. This retrospective nationwide cohort study included patients diagnosed with TB between 2011 and 2017 in South Korea. We performed Fine and Gray regression model analyses to assess the mortality risk of DM classified by cause of death. Of 239,848 patients, 62,435 (26.0%) had DM, and 20,203 died during anti-TB treatment. Of all deaths, 47.9% (9,668) were caused by TB, and the remaining 52.1% (10,535) was attributed to various non-TB-related causes. The mortality rate was higher in the DM than in the non-DM groups in both men and women. DM was associated with a higher risk of TB-related (adjusted hazard ratio [aHR] 1.07, 95% confidence interval [CI] 1.01-1.13) and non-TB-related (aHR 1.21, 95% CI 1.15-1.27) deaths in men; however, only a higher risk of non-TB-related deaths (aHR 1.29, 95% CI 1.20-1.38) in women. Our findings indicate that DM is independently associated with a greater risk of death during anti-TB treatment among patients with TB for both TB-related and non-TB-related deaths.

Abstract
Even though diagnosis and management pathways have been substantially improved over the last years, autoimmune rheumatic diseases (AIRDs) such as rheumatoid arthritis, systemic sclerosis, systemic lupus erythematosus, antiphospholipid syndrome, Sjögren's syndrome, and systemic vasculitides have been linked to elevated rates of cardiovascular morbidity and mortality, primarily secondary to accelerated atherosclerosis. This phenomenon can be partially attributed to the presence of established cardiovascular risk factors but may also be a result of other inflammatory and autoimmune mechanisms that are enhanced in AIRDs. According to the current guidelines, the recommendations regarding cardiovascular disease prevention in patients with AIRDs are not significantly different from those applied to the general population. Herein, we present a review of the current literature on the risk of accelerated atherosclerosis in AIRDs and provide a summary of available recommendations for the management of cardiovascular risk in rheumatic diseases.

Abstract
Background and Aim Recent studies have linked trimethylamine N-oxide (TMAO) to cardiovascular diseases; our study aimed to analyze the association between coronary artery disease (CAD), acute coronary syndrome (ACS), and TMAO. Methods PubMed, Scopus, Embase, and Web of Science were searched using terms such as 'CAD' and 'TMAO'. Only observational controlled studies were included. RevMan software version 5.4 was used for the analysis. Results A significant association was found between the CAD group and increased serum TMAO levels compared with the control group (MD=1.16, 95% CI=0.54-1.78, P=0.0003). This association remained significant among acute coronary syndrome patients (MD=0.98, 95% CI=0.73-1.23, P<0.00001) and was also detected among young and old CAD patients (MD=0.35, 95% CI=0.06-0.64, P=0.02 and MD=1.36, 95% CI=0.71-2.01, P<0.0001, respectively). On further analysis of intestinal metabolites, the authors detected an insignificant association between choline, betaine, carnitine, and CAD. According to our sensitivity analysis, TMAO is an acceptable diagnostic marker for CAD (0.721, SE was 0.0816, 95% CI: 0.561-0.881). Conclusion TMAO is an acceptable diagnostic marker for CAD, with significantly higher levels among these patients regardless of their age. Other metabolites did not show such an association. The role of serum level TMAO in the early diagnosis of CAD should be further explored.

Quantitative and Qualitative Characteristics of Atherosclerotic Plaques on Carotid Arteries in Patients with Antiphospholipid Syndrome: The Role of MDCT Angiography. Diseases 2023; 11:131. [PMID: 37873775 PMCID: PMC10594423 DOI: 10.3390/diseases11040131] [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: 08/29/2023] [Revised: 09/23/2023] [Accepted: 09/24/2023] [Indexed: 10/25/2023] Open
Abstract
INTRODUCTION Antiphospholipid syndrome (APS) is an autoimmune disease characterised by arterious and venous thrombosis, miscarriage, and the presence of antiphospholipid antibodies (aPL) in the blood. As we know, APS is also characterised by accelerated atherosclerotic degeneration with an increased risk of thrombosis in all blood vessels, including the carotid arteries. Carotid artery stenosis can manifest in many different ways. The aim of this study is to present the results of our multidetector computerised tomography angiography (MDCTA) analysis of the carotid arteries in patients with primary and secondary APS compared with a control group. MATERIALS AND METHODS This study examined 50 patients with primary antiphospholipid syndrome (PAPS) and 50 patients with secondary antiphospholipid syndrome (SAPS). The results were compared with a control group also comprising 50 patients. The groups were analysed with respect to age, sex and the presence of well-established risk factors for vascular disease. The study was conducted using MDCTA, where we analysed the quantitative and qualitative (morphologic) characteristics of carotid artery lesions. RESULTS Patients from the control group had significantly elevated levels of cholesterol and triglycerides in comparison with patients with PAPS and SAPS (p < 0.001 and p < 0.05). The results show that carotid artery lesions were significantly more common in patients with APS (PAPS, n = 40, CI95: 0.50-0.75, p = 0.0322 and SAFS, n = 54, CI95: 0.59-0.80, p = 0.0004) than within the control group (n = 23). There was a statistically significant difference between patients with APS and the control group with respect to lesions in the distal segments (n = 27, CI95: 0.67-0.95, p = 0.0001), bulbi and proximal segments (n = 21, CI95: 0.84-1.00, p = 0.000005). The number of patients with one lesion (L) (n = 27) was significantly greater than the number of those with three (n = 10, CI95: 0.56-0.86, p = 0.0051) or four (n = 3, CI95: 0.73-0.98, p = 0.00001) lesions. There were also more patients with two lesions (n = 24) than those with four (n = 3) (CI95: 0.71-0.97, p = 0.00005). Carotid artery stenosis was shown as a percentage of the carotid artery lumen diameter (%DS). Stenosis of up to 30%, was more common in patients in the PAPS group (n = 12) than in the control group (n = 3) (CI95: 0.52-0.96, p = 0.0201), while the SAPS group (n = 17) had an even larger disparity (CI95: 0.62-0.97, p = 0.0017). We observed a highly significant difference in the frequency of stenoses between 30% and 50% DS between the PAPS group (n = 24) and the control group (n = 7) (CI95: 0.59-0.90, p = 0.0023), as well as the SAPS group (n = 30) (CI95: 0.65-0.92, p = 0.0002). A qualitative analysis of plaque morphology revealed that patients with PAPS had significantly more soft tissue lesions (n = 23) compared with calcified lesions (n = 2) (CI95: 0.74-0.99, p = 0.00003), as well as more mixed plaques (n = 9) and calcified plaques (n = 2) (CI95: 0.48-0.98, p = 0.0348). Patients within the SAPS group had significantly more soft tissue (n = 35) than calcified lesions (n = 3) (CI95: 0.79-0.98, p = 0.00000021), as well as more mixed lesions (n = 21) compared with calcified (n = 3) (CI95: 0.68-0.97, p = 0.0002). CONCLUSIONS Our study shows that subclinical manifestations of carotid artery lesions were more common in patients with APS. We came to the conclusion that MDCTA is an accurate diagnostic method because it is a safe method that provides us with a great quantity of accurate information about the characteristics of atheromatous plaques, which aids us in the further planning of treatment for patients with APS.

Abstract
BACKGROUND MicroRNA-146a (miRNA-146a) is a nuclear factor κB (NF-κB)-inducible and inflammation-sensitive miRNA, while papain elicits anti-inflammatory effects by inhibiting monocyte-platelet aggregate (MPA)-mediated NF-κB pathway activation in monocytes. This study aimed to demonstrate the underlying effects of papain on MPA formation-initiated miRNA-146a expression and subsequent action in monocytes. METHODS THP-1 cells were exposed to papain, miRNA-146a mimic and inhibitor, NF-κB inhibitor (BAY11-7082), and platelets. Flow cytometry was used to measure the MPA formation-initiated monocyte activation. Levels of miRNA-146a, cyclooxygenase 2 (COX-2) mRNA and protein, and monocyte chemoattractant protein 1 (MCP-1) were analyzed in monocytes by RT-PCR, western blot, and ELISA. RESULTS The NF-κB inhibitor and miRNA-146a mimics upregulated miRNA-146a expression but suppressed subsequent monocyte activation and expression of COX-2 and MCP-1. Following exposure to papain, the enhanced miRNA-146a transcription induced by MPA-formation was found along with significant inhibition of monocyte activation in a dose-dependent manner. However, the inhibitory tendency was significantly reversed by miRNA-146a inhibitors. Expression of COX-2 mRNA and protein, as well as MCP-1, was inhibited in monocytes by papain, whereas miRNA-146a inhibitors promoted COX-2 and MCP-1 expression. CONCLUSION Our findings suggest that papain can inhibit MPA formation-mediated expression of inflammatory mediators in activated monocytes by upregulating miRNA-146a transcription.

Abstract
Various studies showed that the effect of immune activation is pro-atherogenic and coronary heart disease (CHD) should therefore be considered an autoimmune disease. This study aimed to identify potential immune-related biomarkers, pathways, and the potential regulatory networks underlying CHD. Differentially expressed genes (DEGs) between CHD and control samples were determined by analyzing GSE71226 and GSE9128. The overlapping differential expression immune-related genes (DE-IRGs) for CHD were identified by analyzing the ImmPort database and two GEO databases. A total of 384 DE-IRGs were identified. Subsequently, comprehensive enrichment analyses suggested that DE-IRGs were enriched in immune-related pathways, including autoimmune thyroid disease, the intestinal immune network for IGA production, and downstream signaling events of B cell receptors. The signature of DE-IRGs was validated using an external independent dataset GSE20681 (AUC = 0.875). Furthermore, we conducted protein–protein interaction network analysis and identified eight hub genes, which were most enriched in regulation of defense response, NF-κB signaling pathway, regulation of JNK cascade, and regulation of cytokine production. Moreover, networks of miRNAs-mRNAs and transcription factors (TFs)-mRNA underlying the integrated data were established, involving eight miRNAs and 76 TF-targeting hub genes. Ultimately, 17 SNPs in miRNA-mediated gene networks were identified. We screened potential immune-related genes in CHD and constructed miRNA-mRNA-TF and SNP-miRNA networks, which not only provide inspired insights into the occurrence and the molecular mechanisms of CHD but also lay a foundation for targeting potential biomarkers using immunotherapy and for understanding the molecular mechanisms of CHD.

Abstract
Sjögren Syndrome (SS) seems to be associated with a greater “overall risk” of cardiovascular (CV) and cerebrovascular events. Although not conventionally considered a feature of the disease, CV events represent a major burden in SS patients. CV risk is the consequence of a complex combination of multiple factors, including traditional risk factors and disease-related mechanisms. A complex relationships between disease-related features, endothelial dysfunction and traditional risk factor has been suggested. Several drugs are available for treating the systemic manifestations of SS, however they have shown positive effects on different outcomes of the disease, but until today the data on the role of these drugs on CV events are scarse. Given these data, the aim of this review was to evaluate the risk of CV risk in primary SS and the effect of the drugs on this manifestation.

Abstract
Rheumatoid arthritis (RA) is one of the most frequent inflammatory rheumatic diseases, having a considerably increased prevalence of mortality and morbidity due to cardiovascular disease (CVD). RA patients have an augmented risk for ischemic and non-ischemic heart disease. Increased cardiovascular (CV) risk is related to disease activity and chronic inflammation. Traditional risk factors and RA-related characteristics participate in vascular involvement, inducing subclinical changes in coronary microcirculation. RA is considered an independent risk factor for coronary artery disease (CAD). Endothelial dysfunction is a precocious marker of atherosclerosis (ATS). Pro-inflammatory cytokines (such as TNFα, IL-1, and IL-6) play an important role in synovial inflammation and ATS progression. Therefore, targeting inflammation is essential to controlling RA and preventing CVD. Present guidelines emphasize the importance of disease control, but studies show that RA- treatment has a different influence on CV risk. Based on the excessive risk for CV events in RA, permanent evaluation of CVD in these patients is critical. CVD risk calculators, designed for the general population, do not use RA-related predictive determinants; also, new scores that take into account RA-derived factors have restricted validity, with none of them encompassing imaging modalities or specific biomarkers involved in RA activity.

Abstract
BACKGROUND Toxoplasma gondii is a worldwide protozoon that can infect all nucleated vertebrate cells. Little information is available about the association between T. gondii infection and coronary atherosclerosis. METHODS A total of 320 cases were enrolled (160 patients with coronary atherosclerosis and 160 non-atherosclerotic individuals). Blood samples were collected to measure anti-T. gondii immunoglobulin G (IgG) antibodies using enzyme-linked immunosorbent assay (ELISA) and serum lipid profile. Coronary angiogram was also performed. RESULTS The seroprevalence of anti-Toxoplasma antibodies in atherosclerotic and non-atherosclerotic individuals was 63.1% and 46.2%, respectively, with higher levels of anti-T. gondii IgG in atherosclerotic patients. Consumption of contaminated water, unwashed fruits and vegetables and raw meat and contact with soil were significant risk factors for Toxoplasma infection. Significant differences were detected in serum levels of low-density lipoproteins, triglycerides and cholesterol between both groups. Positive correlations were detected between ELISA titres and serum levels of low-density lipoproteins, triglycerides and cholesterol, disease severity and the number of affected vessels. Male gender and contact with soil had a significant association with positive T. gondii serology in atherosclerotic patients. CONCLUSIONS Patients with coronary atherosclerosis have a high prevalence of T. gondii infection. More studies are crucial to elucidate the mechanisms underlying the effects of chronic toxoplasmosis on coronary atherosclerosis.

Abstract
Although inflammation is a host defense mechanism, chronic inflammation mediates several diseases, including cancer, allergy, asthma, and autoimmune diseases, and reportedly, it is associated with a 60% mortality rate. There are several reports on the anti-inflammatory effects of Curcuma longa and Allium hookeri. However, although they can be used as culinary materials and have biological effects, they are not effective anti-inflammatory agents. In this study, we evaluated the synergic effect of C. longa and A. hookeri in order to confirm the possibility of a new anti-inflammatory agent. Based on cell viability and cytokine analyses, the appropriate ratio of C. longa and A. hookeri was confirmed using an air pouch animal model. Then, the anti-inflammatory effect of C. longa and A. hookeri co-treatment was evaluated by measuring the immune cell count and cytokines in the exudate and by comparing the morphological changes and cytokines in inflamed skin samples. Additionally, we evaluated the NF-κB/COX-2 pathway and iNOS levels. The active constituents detected in C. longa were demethoxycurcumin and bisdemethoxycurcumin, and that detected in A. hookeri was methylsulfonylmethane. An in vitro assessment determined the appropriate drug ratio as 3:7. In a carrageenan-induced inflammatory model, co-treatment effectively suppressed inflammatory cytokines, including IFN-γ, IL-1β, IL-6, IL-13, and IL-17, and recovered inflammation-related morphological changes in the skin. The anti-inflammatory effect of the co-treatment was mediated through the NF-κB/COX-2 pathway and iNOS inhibition. We concluded that co-treatment with C. longa and A. hookeri synergistically inhibited inflammation via the NF-κB/COX-2/iNOS pathway.

Abstract
BACKGROUND Increased risk of coronary heart disease has been observed in several chronic inflammatory disorders, including chronic infection. However, data on the association between tuberculosis and risk of coronary heart disease are limited. METHODOLOGY This systematic review and meta-analysis identified all cohort studies that compared the risk of coronary heart disease among patients with tuberculosis versus individuals without tuberculosis and summarized their results together. Literature search was independently conducted by two investigators using MEDLINE and EMBASE database up to August 2019. Point estimates and standard errors from each study were pooled together using the generic inverse variance method of DerSimonian and Laird. RESULTS A total of four cohort studies met the eligibility criteria and were included into the meta-analysis. The pooled analysis found that patients with tuberculosis have an increased risk of developing coronary heart disease with the pooled risk ratio of 1.76 (95% CI, 1.05-2.95; I2 of 97%). CONCLUSION A significantly increased risk of coronary heart disease among patients with tuberculosis was demonstrated by the current study.

Abstract
Background Inflammation plays important roles in the pathogenesis of acute coronary syndrome (ACS). Statins exert positive effects on the plaque stabilization through anti‐inflammation, however, the detailed mechanism is still under investigation. Hypothesis Studies suggest that the Th17/Treg functional imbalance takes key part in the plaque destabilization and the onset of ACS. We hypothesized that intensive statin therapy could ameliorate the Th17/Treg imbalance in patients with ACS. Methods Sixty‐six patients with non‐ST elevation acute coronary syndrome (NSTE‐ACS) were randomized to conventional group and intensive group. Peripheral blood samples were collected on admission and after atorvastatin treatment. The frequencies of circulating Th17 cells and Treg cells, the levels of cytokines associated with Th17 cells (IL‐17, IL‐6 and IL‐23) and associated with Treg cells (IL‐10 and TGF‐β1) were measured through flow cytometry and ELISA assay respectively. Results One week after therapy, the frequencies of circulating Th17 cells of both the groups decreased and the frequencies of circulating Treg cells increased significantly, compared with the basal levels. Furthermore, the decreased frequencies of circulating Th17 cells and the increased frequencies of circulating Treg cells in the intensive group were significantly higher than those in the conventional group. In consistence, the decreased accumulation of IL‐17, IL‐6 and IL‐23 (cytokines relevant to Th17 cells) and the increased accumulation of IL‐10 and TGF‐β1 in peripheral blood were displayed in both groups. The changes are more significant in the intensive group. Conclusion Intensive statins therapy could ameliorate the Th17 and Treg functional imbalance in patients with ACS.

Abstract
Cardiovascular disease (CVD) is the leading cause of death worldwide, especially in developed countries, and atherosclerosis (AS) is the common pathological basis of many cardiovascular diseases (CVDs) such as coronary heart disease (CHD). The role of the gut microbiota in AS has begun to be appreciated in recent years. Trimethylamine N-oxide (TMAO), an important gut microbe-dependent metabolite, is generated from dietary choline, betaine, and L-carnitine. Multiple studies have suggested a correlation between plasma TMAO levels and the risk of AS. However, the mechanism underlying this relationship is still unclear. In this review, we discuss the TMAO-involved mechanisms of atherosclerotic CVD from the perspective of inflammation, inflammation-related immunity, cholesterol metabolism, and atherothrombosis. We also summarize available clinical studies on the role of TMAO in predicting prognostic outcomes, including major adverse cardiovascular events (MACE), in patients presenting with AS. Finally, since TMAO may be a novel therapeutic target for AS, several therapeutic strategies including drugs, dietary, etc. to lower TMAO levels that are currently being explored are also discussed.

Abstract
Background Cyclooxygenase-2 (COX-2) plays an important role in the monocyte-platelet aggregate (MPA)-medicated inflammatory response and possible coronary artery disease (CAD). This study aimed to assess the predicting significance of COX-2 expression in peripheral blood monocyte for CAD. Methods A total of 66 patients with CAD including stable angina (SA) and unstable angina (UA) were enrolled. The inflammatory indexes including white blood cell (WBC) count, high-sensitive C reactive protein (hs-CRP), serum monocyte chemoattractant protein-1 (MCP-1) and MPA levels were measured. The western-blotting assay and reverse transcription-polymerase chain reaction (RT-PCR) analysis were used to detect the COX-2 expression in peripheral blood monocytes. Furthermore, the correlation between COX-2 expression and MPA levels, and the association of COX-2 expression with CAD risk were assessed. Results The UA patients demonstrated higher levels of inflammatory indexes than the SA patients (P<0.001). Simultaneously, higher MPA levels and enhanced COX-2 expression were observed in the UA patients (P<0.01). The patients with enhanced COX-2 expression exhibited higher MPA than those without (P<0.01), and patients with increased MPA also demonstrated enhanced COX-2 expression (P<0.001). Moreover, the levels of COX-2 protein expression was positively related to the MPA formation rates (R2=0.4933, P<0.01), and enhanced COX-2 expression was independently associated with CAD risk [odds ratio (OR): 6.322, 95% confidence interval (CI): 4.544-8.978 ]. Conclusions The COX-2 expression of peripheral blood monocytes can be used as an independent predictor for CAD.

Abstract
Chronic inflammation is one of the main determinants of atherogenesis. The traditional medications for treatment of atherosclerosis are not very efficient in targeting atherosclerotic inflammation. Most of these drugs are non-selective, anti-inflammatory and immunosuppressive agents that have adverse effects and very limited anti-atherosclerotic effects, which limits their systemic administration. New approaches using nanoparticles have been investigated to specifically deliver therapeutic agents directly on atherosclerotic lesions. The use of drug delivery systems, such as polymeric nanoparticles, liposomes, and carbon nanotubes are attractive strategies, but some limitations exist. For instance, nanoparticles may alter the drug kinetics, based on the pathophysiological mechanisms of the diseases. In this review, we will update pathophysiological evidence for the use of nanoparticles to reduce inflammation and potentially prevent atherogenesis in different experimental models.

Abstract
PURPOSE OF REVIEW Night shift work has become highly prevalent in our 24/7 societies, with up to 18% of the US work force working alternate shift schedules. However, studies indicate that there may be adverse health effects of chronic night work across diverse populations. These effects are likely due to misalignment of the circadian system with work schedules, mediated by the system's primary marker melatonin as well as other downstream molecules. RECENT FINDINGS Melatonin has multiple biologic actions that are relevant to cardiometabolic disease, including modulation of oxidative stress, inflammation, and (via the melatonin receptor) vasoconstriction. Behavioral traits, such as chronotype and meal timing, have recently been shown to interact with the effects of night work on cardiometabolic health. Together with recent findings suggesting a role for circadian genes in cardiometabolic risk, the interactions of night shift work and behavioral traits are likely to facilitate novel treatment and prevention approaches for cardiovascular disease and type 2 diabetes, incorporating aspects of clock and timing.

Papain Ameliorates the MPAs Formation-Mediated Activation of Monocytes by Inhibiting Cox-2 Expression via Regulating the MAPKs and PI3K/Akt Signal Pathway. BIOMED RESEARCH INTERNATIONAL 2018; 2018:3632084.

Abstract
Monocytes activation and subsequent inflammatory response mediated by monocyte-platelet aggregates (MPAs) formation play the key roles in the early pathogenesis of atherosclerosis (AS). Exploration of novel drugs to ameliorate MPAs formation-mediated monocytes activation would be helpful for the treatment of AS patients. Papain has definite pharmacological effects including antiplatelet, thrombolysis, and anti-inflammation. However, its effect on MPAs formation and the following monocytes activation remains vague. This study aimed to illustrate the underlying mechanisms of papain on MPAs formation-initiated monocytes activation in vitro. In this study, Papain, Cox-2 inhibitor (NS-398), and NF-κB agonist (TNF-α) were used as the treating agents, respectively. MPAs formation and activated monocytes were measured by flow cytometry (FCM). Cox-2 mRNA, MCP-1, and proteins of Cox-2 and NF-κB signal pathway were detected by qRT-PCR, ELISA, and western blotting, respectively. As we observed, papain exhibited the powerful inhibitory effects on thrombin-mediated MPAs formation and monocytes activation in a concentration-dependent manner as what Cox-2 inhibitor demonstrated. However, the inhibitory tendency was significantly reversed by TNF-α. We also discovered that both Cox-2 mRNA and protein expression as well as the release of MCP-1 of monocyte was inhibited by either papain or NS-398, but TNF-α stimulated Cox-2 expression and release of MCP-1. The results of western blotting assay indicated that thrombin-mediated proteins expression of MAPKs and PI3K/Akt signal pathway was inhibited by papain and NS-398. However, TNF-α notably abated the inhibitory effects of papain on the process of MPAs-initiated monocytes activation. Our findings suggest that papain can inhibit the MPAs formation-mediated activation of monocytes by inhibiting the MAPKs and PI3K/Akt signal pathway.

Abstract
Atherosclerosis is regarded as one of the leading causes of mortality and morbidity in the world. Nowadays, it seems that atherosclerosis cannot be defined merely through the Framingham traditional risk factors and that autoimmunity settings exert a remarkable role in its mechanobiology. Individuals with autoimmune disorders show enhanced occurrence of cardiovascular complications and subclinical atherosclerosis. The mechanisms underlying the atherosclerosis in disorders like rheumatoid arthritis, systemic lupus erythematosus, antiphospholipid syndrome, systemic sclerosis and Sjögren's syndrome, seem to be the classical risk factors. However, chronic inflammatory processes and abnormal immune function may also be involved in atherosclerosis development. Autoantigens, autoantibodies, infectious agents and pro-inflammatory mediators exert a role in that process. Being armed with the mechanisms underlying autoimmunity in the etiopathogenesis of atherosclerosis in rheumatic autoimmune disorders and the shared etiologic pathway may result in substantial developing therapeutics for these patients.

Abstract
No previous studies have investigated the prevalence of latent tuberculosis infection (LTBI) among patients with erectile dysfunction (ED) or its contribution to the development of high-grade ED through a process of chronic inflammation-induced atherosclerosis. The aim of this study was to determine the frequency of LTBI among patients with erectile dysfunction and to explore the contribution of LTBI to high-grade ED. For all the study sample, clinical evaluation, imaging studies, and laboratory investigations were provided. Evaluation included, but was not confined to, scrotal ultrasonography, tuberculin skin test, and QuantiFERON-TB Gold test. The study sample mean ± SD age was 47.9 ± 13.6 years. Approximately 30% of the patients had LTBI and 43% had high-grade ED. After a multivariate analysis, it was found that older age (≥40 years) (OR, 5.2; 95% CI, 1.9-54.6; p 0.004), metabolic syndrome (MS) (OR, 3.4; 95% CI, 1.3-48.2; p 0.016), and LTBI (OR, 4.1; 95% CI, 1.7-61.3; p 0.021) were significantly, independently associated with high-grade ED as opposed to low-grade ED. In conclusion, the prevalence of LTBI among patients with high-grade ED is higher than among those with low-grade ED. In addition to LTBI, older age and MS are associated with high-grade ED as opposed to low-grade ED.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disease defined by accelerated atherosclerosis, arterial and venous thrombosis, fetal loss, and the presence of antiphospholipid antibodies (aPL) in the serum and which leads to the occurrence of various vascular events. Nonspecific abdominal pain can be one of the symptoms due to changes on visceral blood vessels. The goal of our work is to show the results we obtained in multidetector computed tomography (MDCT) angiography examination of visceral arteries, comparing patients with primary antiphospholipid syndrome (PAPS) and secondary antiphospholipid syndrome (SAPS) with control group. In this study, we analyzed 50 patients with primary PAPS and 50 patients, with secondary SAPS. The results were compared to 50 patients in the control group. The groups were compared in terms of age, gender, and the most common risk factors except for the lipid status, since controls had significantly higher levels of cholesterol and triglycerides. The study was conducted on 64-MDCT, on which we analyzed quantitative and morphological characteristics of the blood vessel lesions. Patients from the control group had statistically significant elevation of cholesterol and triglyceride levels compared to the patients with SAPS and PAPS (p < 0.001 and p < 0.05). The results showed that the frequency of changes is statistically (p < 0.05 and p < 0.001) more common in patients with PAPS and SAPS than in the control group. Statistically significant difference between the groups was found in superior and inferior mesentery arteries. Analyzing the number of lesions, there was statistically high difference between the patients with one and two lesions than in patients with four or more lesions (p < 0.001), lower difference compared to the patients with three lesions (p < 0.01), while there was low, but yet statistically important difference between the patients with three lesions and those with five or more blood vessel lesions (p < 0.05). Analyzing percentage of diameter stenosis, we established that the lesions in the groups of 0-30% diameter stenosis (DS) and 30-50% DS in patients with PAPS (n = 42) and SAPS (n = 44) are more common than in the control group (n = 18, p < 0.05). Analyzing the qualitative characteristics of plaques, we established significantly higher frequency of soft tissue and mixed lesions than calcified ones in patients with PAPS and SAPS (p < 0.001; p < 0.05). Our study showed that the subclinical manifestation of the changes on visceral arteries is more common in patients with APS. Patients with abdominal pain were those with two or more lesions, and according to our results, majority had PAPS. Because of its safety and accuracy, the method of choice is MDCT angiography in monitoring the progression of disease.

Abstract
The prevalence of thrombophilia and dyslipidemia among young survivors of acute coronary syndrome has not been clearly defined. The purpose of the current study was to investigate the prevalence of multiple markers of thrombophilia and dyslipidemia in a cohort of consecutive young survivors of acute coronary syndrome. The study cohort included 156 consecutive young patients (men <45 and women <50 years), admitted to the intensive cardiac care unit with newly diagnosed acute coronary syndrome. Analysis included baseline, clinical and epidemiological characteristics, angiographic coronary anatomy, echocardiographic evaluation, extensive lipid and thrombophilia laboratory profiles, and in-hospital and 1-year clinical outcomes for all patients. Acute myocardial infarction was diagnosed in 142 (92 %) patients, of whom 108 (72 %) had ST-segment elevation. Eighteen (12 %) patients had no traditional risk factors. Low levels of high-density lipoprotein (<40 mg/dL) were found in 101 (65 %) patients, and 49 (34 %) patients had elevated levels of lipoprotein(a) (Lp(a)) (>30 mg/dL). Eighteen (12 %) patients were diagnosed with antiphospholipid antibody syndrome (APS), and 73 (47 %) had at least one laboratory finding consistent with thrombophilia. Patients with APS had significantly higher levels of Lp(a) (46 ± 32 vs. 29 ± 31 mg/dL, p = 0.005). APS is a common prothrombotic state found in young survivors of acute coronary syndrome. Lp(a) levels are elevated among APS patients who present with premature acute coronary syndrome.

Abstract
Toll-like receptors (TLRs) participate in the innate immune response and trigger the immune responses of the body. Systemic lupus erythematosus (SLE) is an autoimmune disease of unknown aetiology, characterized by an excessive autoimmune response in the body affecting the connective tissues. The disease is possibly triggered by both environmental aetiological factors and pathological organic processes such as exposure to sunlight, chronic infectious processes and genetic factors. Conversely, periodontal disease is an infectious disease caused by microorganisms in the oral cavity, resulting in a chronic inflammatory process which continuously stimulates the immune response, thus causing damage to the periodontal tissues. The expression of both TLR-2 and TLR-4 receptors are increased in both SLE and periodontal disease. Periodontitis might trigger excessive activation of immune response occurring in SLE by maintaining a high expression of TLRs, leading in turn to the acceleration of the onset and progression of autoimmune reactions. In addition, periodontal treatment is able to reduce the expression of these receptors and therefore the symptoms of SLE. Here we discuss the possible interaction between SLE and periodontitis, and suggest further studies evaluating common features in both factors that could explored, due to morbidity and mortality of SLE and the high incidence of periodontal infections around the world.

Abstract
Proteomic strategies provide a valuable tool kit to identify proteins involved in diseases. With recent progress in MS technology, high throughput proteomics has accelerated protein identification for potential biomarkers. Numerous biomarker candidates have been identified in several diseases, and many are common among pathologies. An overall strategy that could complement and strengthen the search for biomarkers is combining protein identity with biological outcomes. This review describes an emerging framework of bridging bioactivity to protein identity, exploring the possibility that some biomarkers will have a mechanistic role in the disease process. A review of pulmonary, cardiovascular, and CNS biomarkers will be discussed to demonstrate the utility of combining bioactivity with identification as a means to not only find meaningful biomarkers, but also to uncover functional mediators of disease.

Abstract
The imbalance of CD4(+)CD25(+) regulatory T (Treg) cells and Th17 cells has shown to be involved in pathogenesis of atherosclerosis and acute coronary syndrome [ACS, including unstable angina (UA) and acute myocardial infarction (AMI)]. The purpose of this study is to explore the significance of Treg/Th17 ratio in early diagnosis for ACS. We detected expression of Treg and Th17 in patients with AMI, UA, stable angina, and subjects with normal coronary arteries at the time of admission. Our results showed that ACS patients have a significant increase of Th17 number, but a marked decline of Treg/Th17 ratio, Treg number, and Treg function. Significant positive correlations in Th17 frequency and negative correlation in Treg frequency, Treg/Th17 ratio were found to levels of oxidized low-density lipoprotein (Ox-LDL), high sensitive C-reactive protein (hsCRP), Lipoprotein (a) [Lp(a)], and Creatine kinase-MB(mass) (CK-MBmass) in serum. Receiver-operating characteristic curves shown that the predictive specificity and sensitivity of Treg/Th17 ratio for ACS and AMI was the highest among all the five markers: Ox-LDL, hsCRP, Lp(a), CK-MBmass, and Treg/Th17 ratio. In conclusion, Treg/Th17 ratio appeared to be a novel indicator for early diagnosis of ACS.

Abstract
Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease associated with accelerated atherosclerosis independent of traditional risk factors. Statins, the 3-hydroxy-3-methyl-glutaryl coenzyme A (HMG-CoA) reductase inhibitors, have been widely prescribed for hyperlipidemia, which could slow the atherosclerosis progression, and reduce cardiovascular disease events. Nonetheless, accumulated evidences suggested that statins exert immunomodulatory and anti-inflammatory functions independent of their lipid-lowering effects. By the virtue of pleiotropic immunomodulatory property, statins may be applied for the treatment of both autoimmunity and atherosclerosis in patients with SLE. Interestingly, it has been well documented that regulatory T cells (Tregs) are involved in the pathogenesis of SLE as well as atherosclerosis. Meanwhile, studies have shown that statins could induce augmented number of Tregs with increased functional inhibitory properties. Thus, we hypothesized that the effect of statins ameliorating lupus disease manifestations and lupus-mediated atherogenesis might be mediated, at least partly, via the activation of Tregs. To our knowledge, this is the first hypothesis focused on that Tregs might be involved in the immunomodulatory effect of statins on SLE and SLE-related atherosclerosis.

Abstract
Atherosclerosis is a chronic inflammatory disorder characterized by immune cell activation, inflammation driven plaque formation and subsequent destabilization. In other disorders of an inflammatory nature, the chronic inflammatory state per se has been linked to acceleration of the atherosclerotic process which is underlined by an increased incidence of cardiovascular disease (CVD) in disorders such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA) and antiphopholipid (Hughes) syndrome (APS). SLE is an autoimmune disease that may affect any organ. Premature coronary heart disease has emerged as a major cause of morbidity and mortality in SLE. In addition to mortality, cardiovascular morbidity is also markedly increased in these patients, compared with the general population. The increased cardiovascular risk can be explained only partially by an increased prevalence of classical risk factors for cardiovascular disease; it also appears to be related to inflammation. Inflammation is increasingly being considered central to the pathogenesis of atherosclerosis and an important risk factor for vascular disease. Recent epidemiologic and pathogenesis studies have suggested a great deal in common between the pathogenesis of prototypic autoimmune disease such as SLE and that of atherosclerosis. We will review traditional risk factors for CVD in SLE. We will also discuss the role of inflammation in atherosclerosis, as well as possible treatment strategies in these patients.

Abstract
OBJECTIVES Circulating IgG antibodies to oxidized low-density lipoprotein (anti-oxLDL) have been implicated in the development of atherosclerotic plaques. In this study, we investigated the prognostic value of IgG anti-oxLDL antibodies in patients with acute coronary syndrome (ACS). METHODS In total 54 patients with ACS and 41 matched healthy controls were involved in this prospective study. Serum IgG anti-oxLDL levels were assessed by ELISA. RESULTS Higher IgG anti-oxLDL levels were found in patients with ACS versus controls (22.8 ± 23.3 vs. 7.5 ± 5.27 EU/ml, p < 0.0001). IgG anti-oxLDL concentrations were significantly higher in ACS patients with unstable clinical complications (circulatory insufficiency, malignant arrhythmias, recurring ischaemic pain, positive stress-test, need for urgent coronary intervention or sudden cardiac death) versus those without such complications (30.0 vs. 11.7 EU/ml, p < 0.001). Twelve patients (22%) were taking statins. Patients on statins had a significant reduction in clinical complications (33%) versus patients not receiving statin therapy (61%). IgG anti-oxLDL levels were also different in these two groups (11.4 vs. 25.8 EU/ml, respectively; p = 0.03). Serum IgG anti-oxLDL levels correlated with the subsequent development of unstable coronary events. Levels of anti-oxLDL significantly decreased in response to statin therapy, independently of its lipid-lowering effect. CONCLUSIONS Anti-oxLDL antibodies are involved in ACS. The association of anti-oxLDL with unstable clinical complications may indicate the role of this antibody in plaque destabilization.

Abstract
OBJECTIVE Although multiple diseases associated with primary Sjögren's syndrome (pSS) have been reported, reliable data regarding the prevalence of specific medical comorbidities among patients with pSS remain sparse. We investigated the prevalence and risk for a broad spectrum of medical conditions among patients with pSS in Taiwan. METHODS A total of 1974 patients with pSS were eligible for inclusion in the study group. We randomly selected 9870 enrollees matched with the study subjects, using the Taiwan National Health Insurance Research Dataset for 2006 and 2007, inclusive. Conditional logistic regression analyses conditioned on sex, age, monthly income, and level of urbanization of the patient's community were used to calculate the odds ratios (OR) of various comorbid conditions. RESULTS Pearson chi-square tests revealed that patients with pSS had significantly higher prevalence of hyperlipidemia, cardiac arrhythmias, headaches, migraines, fibromyalgia (FM), asthma, pulmonary circulation disorders, hypothyroidism, liver disease, peptic ulcers, hepatitis B, deficiency anemias, depression, and psychoses. Conditional regression analyses showed that, compared to patients without the condition, patients with pSS were more likely to have hyperlipidemia (OR 1.42), cardiac arrhythmias (OR 1.32), headaches (OR 1.47), migraines (OR 1.86), FM (OR 1.71), asthma (OR 1.54), pulmonary circulation disorders (OR 1.42), hypothyroidism (OR 2.37), liver disease (OR 1.89), peptic ulcers (OR 1.88), hepatitis B (OR 2.34), deficiency anemias (OR 1.33), depression (OR 2.57), and psychoses (OR 2.15). CONCLUSION The prevalence of several comorbidities was increased among the patients with pSS. Our study provides epidemiological data for comorbidities among pSS patients in an ethnic Chinese population.

Abstract
Helicobacter pylori (H. pylori) is a predominant pathogen that causes not only gastroduodenal diseases but also extra-alimentary tract diseases. In this study, we demonstrated that H. pylori infection promoted atherogenesis in heterozygous apoe(+/ --) ldlr(+/--) mice. The male mice were fed with high fat diet from the age of 6 weeks. At the age of 16 weeks, development of atherosclerotic lesions was observed in the H. pylori-infected mice, and it seemed to be associated with an elevation of Th1-immune response against H. pylori origin-heat shock protein 60 (Hp-HSP60) and an increment of transendothelial migration of T cells. Subcutaneous immunisation with Hp-HSP60 or H. pylori eradication with antibiotics significantly reduced the progression of atherosclerosis, accompanied by a decline of Th1 differentiation and reduction of their chemotaxis beyond the endothelium. Thus, oral infection with H. pylori accelerates atherosclerosis in mice and the active immunisation with Hp-HSP60 or the eradication of H. pylori with antibiotics can moderate/prevent cellular immunity, resulting in a reduction of atherosclerosis.

Abstract
Atherosclerosis is a disease of the vascular wall, which predominantly affects large and medium-sized arteries. It represents a leading cause of morbidity and mortality in the Western world. In the last few decades, it has been clearly shown that immune system plays a relevant role in atherogenesis. The effectors of both innate and adaptive immunity, including immune cells, cell or soluble receptors, cytokines, chemokines, complement components or coagulation systems, and autoantibodies are able to modulate atherosclerosis. Among proteins belonging to innate immunity, the highly conserved pentraxin family, which encompass C-reactive protein (CRP), serum amyloid P (SAP), and the long pentraxin 3 (PTX3) seems to be directly involved in the induction and progression of atherosclerosis. By immunohistochemical staining, pentraxins were found within the atherosclerotic plaques where they could play a key role interacting with atherogenic-modified lipoproteins, favoring the formation of foam cells, and exerting a proinflammatory action. Pentraxin serum levels have been shown to be associated with clinical and subclinical atherosclerosis in general population. Antibodies against pentraxins have been demonstrated in patients with autoimmune diseases, but their role in atherogenesis is still controversial.

Abstract
Evolution of immunopathological diseases is usually slow and progressive. Non-differentiated collagen disease (NDC) or the term "undifferentiated connective tissue disease" (UCTD) represents a stage of disease where clinical symptoms and serological abnormalities suggest autoimmune disease, but they are not sufficient to fulfill the diagnostic criteria of any well-established connective tissue disease (CTD) such as systemic lupus erythematosus (SLE), Sjögren's syndrome, mixed connective tissue disease (MCTD), systemic sclerosis (SSc), polymyositis/ dermatomyositis (PM/DM) or rheumatoid arthritis (RA). 30-40 percent of patients presenting undifferentiated profile develops and reaches the stage of a well defined systemic autoimmune disease during five years follow up, while 60 percent remains in an undifferentiated stage.In the stage of NDC, immunoregulatory abnormalities and endothelial dysfunction are present. In conclusion, NDC represents a dynamic state, and it is important to recognize the possibility of a progression to a definite systemic autoimmune disease.

Abstract
Autoimmunity may evolve in predisposed individuals following an exogenous trigger. Autoimmunity is affected by genetic, immune, hormonal, and environmental factors. Immune mechanisms in heart diseases are complex and often not completely understood. Several cardiac disorders are believed to be mediated by an immune reaction. Both humoral and cellular immunity are associated with the development of myocarditis, dilated cardiomyopathy, heart failure, rheumatic fever, and atherosclerosis. Here the diagnostic criteria and autoimmune aspects of autoimmune-mediated cardiac disorders are reviewed. New diagnostic criteria for "autoimmune dilated cardiomyopathy" were recently suggested by the authors. They presume that establishing a dominant autoimmune etiology in some patients will have clinical significance because these patients will potentially gain the greatest benefit from immunosuppressive and immunomodulating treatments.

Abstract
Recently, the term "inflammaging" was coined by Franceshci and colleagues to characterize a widely accepted paradigm that ageing is accompanied by a low-grade chronic up-regulation of certain pro-inflammatory responses. Inflammaging differs significantly from the traditional five cardinal features of acute inflammation in that it is characterized by a relative decline in adaptive immunity and T-helper 2 responses and is associated with increased innate immunity by cells of the mononuclear phagocyte lineage. While the over-active innate immunity characteristic of inflammaging may remain subclinical in many elderly individuals, a portion of individuals (postulated to have a "high responder inflammatory genotype") may shift from a state of "normal" or "subclinical" inflammaging to one or more of a number of age-associated diseases. We and others have found that IFN-γ and other pro-inflammatory cytokines interact with processing and production of Aβ peptide, the pathological hallmark feature of Alzheimer's disease (AD), suggesting that inflammaging may be a "prodrome" to AD. Although conditions of enhanced innate immune response with overproduction of pro-inflammatory proteins are associated with both healthy aging and AD, it is suggested that those who age "well" demonstrate anti-inflammaging mechanisms and biomarkers that likely counteract the adverse immune response of inflammaging. Thus, opposing the features of inflammaging may prevent or treat the symptoms of AD. In this review, we fully characterize the aging immune system. In addition, we explain how three novel treatments, (1) human umbilical cord blood cells (HUCBC), (2) flavanoids, and (3) Aβ vaccination oppose the forces of inflammaging and AD-like pathology in various mouse models.

Abstract
Several systemic autoimmune conditions, including rheumatoid arthritis, systemic lupus erythematosus and antiphospholipid syndrome, are characterised by enhanced atherosclerosis and, consequently, higher cardiovascular morbidity and mortality rates. The association of these diseases with atherosclerosis suggests a common pathogenic mechanism. Genomic and proteomic studies performed on atherosclerotic plaques have further confirmed the presence of a gene and protein profile similar to that observed in autoimmune diseases with cardiovascular risks. Human sera and body fluids have been analysed and have resulted in the identification of auto-antibodies that can be used as diagnostic markers in specific autoimmune diseases, and proteomic fingerprints of blood cells, tissues and body fluids have resulted in the identification of individual proteins or patterns of protein expression that are deregulated. The information provided by these proteomic studies is of diagnostic and therapeutic potential. In this review, we discuss new approaches available for assessing thrombotic risk in autoimmune diseases, focusing in the genomic and proteomic methods now available to deep into the origin of the mechanisms associated with vascular involvement in systemic autoimmune diseases. The increasing data available suggests that when treating patients with these autoimmune disorders, paying attention to the increased risk of cardiovascular disease is essential.

Abstract
Excessive lipid peroxidation is a major factor of accelerated atherosclerosis, observed in patients with systemic lupus erythematosus (SLE). We aimed at the present study to determine the paraoxonasel (PON1) and arylesterase activities, and lipid-profile in 37 SLE patients and 30 age-/sex-matched controls. Association was analyzed between PON1 activity and SLEDAI, CRP, anti-oxLDL, and antiphospholipid antibody (aPL) levels, steroid dose, and atherothrombotic events. The age of patients was 40.8 +/- 13.9 year, follow-up time 6.7 +/- 6.2 year, SLEDAI 2 (0-15). PON1 and arylesterase activities were measured spectrophotometrically using paraoxon and phenyl acetate as substrates, respectively. Phenotypic distribution of PON1 was determined by dual substrate method. We measured antioxLDL and aPL levels by ELISA, the CRP by automated immunoassay. PON1 activity (121.9 +/- 65.9 U/mL) was reduced significantly (P < 0.001) in SLE as compared to control (188.1 +/- 78.9 U/mL), but arylesterase activity was not different. A negative correlation was found between PON1 activity and age. PON1 activity did not correlate with other measured parameters. Reduced PON1 activity associated with clinical atherothrombotic complications (P < 0.01). High activity BB phenotype was not present in SLE. Lipid parameters (TC, LDL-C, HDL-C, ApoAI, and ApoB) were within normal range in both groups. Results indicated reduced PON1 activity in lupus patients despite long disease duration and low inflammatory activity, and it was evidenced as a risk for atherosclerotic complications. As the arylesterase activity was normal, further examinations are required to find other mechanisms, such as anti-PON1 antibodies, genetic polymorphisms, and difference in distribution of HDL-subfractions or enzyme abnormalities in HDL remodeling.

Abstract
Antiphospholipid and anti-oxidized LDL (anti-oxLDL) antibodies are associated with thrombosis and atherosclerosis. Rheumatoid arthritis (RA) is characterized by excess atherosclerosis and cardiovascular diseases. Our aim was to determine whether antiphospholipid and anti-oxLDL antibodies are associated with early atherosclerotic changes in RA. The levels of IgG and IgM anticardiolipin, IgG and IgM anti-beta-2-glycoprotein-I and anti-oxLDL autoantibodies have been evaluated in 82 patients having RA. Carotid artery intima-media thickness (IMT) was measured in the carotid arteries in the common carotid, bifurcation and internal carotid arteries. Elevated levels of IgG anticardiolipin antibodies were detected in 17 of 82 (21%) RA patients, including 7 with medium-to-high levels considered being clinically relevant. These patients had significantly elevated mean carotid and carotid bifurcation IMT compared with RA patients without elevated anticardiolipin. No such association was found regarding other autoantibodies tested. Anticardiolipin antibodies are prevalent in RA and are associated with early atherosclerotic changes, supporting a rational for measuring them in RA, and upon detection treat the patients in order to decrease chances of atherosclerosis progression and thrombosis.

Abstract
The aim of this study was to examine whether heat-shock protein (HSP)-65 autoantibodies are associated with early atherosclerosis in rheumatoid arthritis (RA). Intima-media thickness (IMT) was measured in the carotid arteries of 100 RA patients and 69 control subjects. The IMT was evaluated on both carotid arteries in the common carotid, bifurcation, and internal arteries. Every patient underwent anti-HSP-65 antibody evaluation. Anti-HSP-65 antibodies were not more prevalent among patients compared with controls. Among controls, patients having "positive" anti-HSP-65 tended to have increased carotid artery IMT compared with "negative" patients, whereas among RA patients the opposite association was noted, and positive patients had significantly decreased carotid bifurcation IMT than negative patients without elevated levels of anti-HSP-65. As opposed to the association with cardiovascular diseases and atherosclerosis of anti-HSPs in the general population, among RA patients anti-HSP-65 cannot be regarded as associated with early atherosclerosis.
