Abstract
Sepsis and atherosclerotic cardiovascular disease (ASCVD) are major health challenges involving complex processes like inflammation, renin-angiotensin system (RAS) dysregulation, and thrombosis. Despite distinct clinical symptoms, both conditions share mechanisms mediated by bradykinin. This review explores bradykinin's role in inflammation, RAS modulation, and thrombosis in sepsis and ASCVD. In sepsis, variable kininogen-bradykinin levels may correlate with disease severity and progression, though the effect of bradykinin receptor modulation on inflammation remains uncertain. RAS activation is present in both diseases, with sepsis showing variable or low levels of Ang II, ACE, and ACE2, while ASCVD consistently exhibits elevated levels. Bradykinin may act as a mediator for ACE2 and AT2 receptor effects in RAS regulation. It may influence clotting and fibrinolysis in sepsis-associated coagulopathy, but evidence for an antithrombotic effect in ASCVD is insufficient. Understanding bradykinin's role in these shared pathologies could guide therapeutic and monitoring strategies and inform future research.

Receptor for advanced glycation end products polymorphisms in coronary artery ectasia. Gene 2024; 916:148450. [PMID: 38588932 DOI: 10.1016/j.gene.2024.148450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 03/15/2024] [Accepted: 04/05/2024] [Indexed: 04/10/2024]
Abstract
BACKGROUND Although the implication of receptor of advanced glycation endproducts (RAGE) has been reported in coronary artery disease, its roles in coronary artery ectasia (CAE) have remained undetermined. Furthermore, the effect of RAGE polymorfisms were not well-defined in scope of soluble RAGE (sRAGE) levels. Thus, we aimed to investigate the influence of the functional polymorphisms of RAGE -374T > A (rs1800624) and G82S (rs2070600) in CAE development. METHODS This prospective observational study was conducted in 2 groups selected of 2452 patients who underwent elective coronary angiography (CAG) for evaluation after positive noninvasive heart tests. Group-I included 98 patients with non-obstructive coronary artery disease and CAE, and Group-II (control) included 100 patients with normal coronary arteries. SNPs were genotyped by real-time PCR using Taqman® genotyping assay. Serum sRAGE and soluble lectin-like oxidized receptor-1 (sOLR1) were assayed by ELISA and serum lipids were measured enzymatically. RESULTS The frequencies of the RAGE -374A allele and -374AA genotype were significantly higher in CAE patients compared to controls (p < 0.001). sRAGE levels were not different between study groups, while sOLR1 levels were elevated in CAE (p = 0.004). In controls without systemic disease, -374A allele was associated with low sRAGE levels (p < 0.05), but this association was not significant in controls with HT. Similarly, sRAGE levels of CAE patients with both HT and T2DM were higher than those no systemic disease (p = 0.02). The -374A allele was also associated with younger patient age and higher platelet count in the CAE group in both total and subgroup analyses. In the correlation analyses, the -374A allele was also negatively correlated with age and positively correlated with Plt in all of these CAE groups. In the total CAE group, sRAGE levels also showed a positive correlation with age and a negative correlation with HDL-cholesterol levels. On the other hand, a negative correlation was observed between sRAGE and Plt in the total, hypertensive and no systemic disease control subgroups. Multivariate logistic regression analysis confirmed that the -374A allele (p < 0.001), hyperlipidemia (p < 0.05), and high sOLR1 level (p < 0.05) are risk factors for CAE. ROC curve analysis shows that RAGE -374A allele has AUC of 0.713 (sensitivity: 83.7 %, specificity: 59.0 %), which is higher than HLD (sensitivity: 59.2 %, specificity: 69.0 %), HT (sensitivity: 62.4 %, specificity: 61.1 %) and high sOLR1 level (≥0.67 ng/ml)) (sensitivity: 59.8 %, specificity: 58.5 %). CONCLUSION Beside the demonstration of the relationship between -374A allele and increased risk of CAE for the first time, our results indicate that antihypertensive and antidiabetic treatment in CAE patients causes an increase in sRAGE levels. The lack of an association between the expected -374A allele and low sRAGE levels in total CAE group was attributed to the high proportion of hypertensive patients and hence to antihypertensive treatment. Moreover, the RAGE -374A allele is associated with younger age at CAE and higher Plt, suggesting that -374A may also be associated with platelet activation, which plays a role in the pathogenesis of CAE. However, our data need to be confirmed in a large study for definitive conclusions.

Differential Expression of Circulating Damage-Associated Molecular Patterns in Patients with Coronary Artery Ectasia. Biomolecules 2023; 14:10.

Abstract
Coronary artery ectasia (CAE) is defined as abnormal dilation of a coronary artery with a diameter exceeding that of adjacent normal arterial segment by >1.5 times. CAE is a pathological entity of the coronary arteries and characterized as a variant of coronary atherosclerosis. CAE frequently coexists with coronary artery disease (CAD). While inflammation appears to be involved, the pathophysiology of CAE remains unclear. Damage-associated molecular patterns (DAMPs), defined as endogenous molecules released from stressed or damaged tissue, are deemed as alarm signals by the innate immune system. Inflammatory agents can generate DAMPs and DAMPs can create a pro-inflammatory state. In a prospective cross-sectional study, we enrolled 29 patients with CAE and non-obstructive CAD, 19 patients with obstructive CAD without CAE, and 14 control subjects with normal (control) coronary arteries age- and sex-matched with the CAE patients, to investigate the differential expression of plasma DAMPs. Patients with CAE and non-obstructive CAD had increased plasma levels of the DAMPs S100B, S100A12, HMGB1, and HSP70, the DAMPs receptor TLR4, and miR328a-3p compared to CAD and controls. Plasma levels of the mir328a-3p target the protective soluble form of the DAMPs receptor for advanced glycation end products (sRAGE), and the antioxidant DJ-1 was decreased in both CAE and CAD compared to controls. In an in vitro human umbilical vein endothelial cells model, circulating levels of S100B, HMGB1, HSP70 as well as CAE patient plasma induced inflammatory responses. The differential expression of the DAMPs S100B, HSP70, HMGB1, and their receptors TLR4 and sRAGE in CAE versus CAD makes them attractive novel biomarkers as therapeutic targets and therapeutics.

Abstract
Isolated coronary artery ectasia (CAE) is a relatively rare clinical entity, the pathogenesis of which is poorly understood. More and more evidence is accumulating to suggest a critical inflammatory component. We aimed to elucidate any association between neutrophil to lymphocyte ratio and coronary artery ectasia. A systematic MEDLINE database, ClinicalTrials.gov, medRxiv, Scopus and Cochrane Library search was conducted: 50 studies were deemed relevant, reporting on difference in NLR levels between CAE patients and controls (primary endpoint) and/or on high-sensitive CRP, IL-6, TNF-a and RDW levels (secondary endpoint), and were included in our final analysis. (PROSPERO registration number: CRD42021224195). All inflammatory biomarkers under investigation were found higher in coronary artery ectasia patients as compared to healthy controls (NLR; SMD = 0.73; 95% CI: 0.27–1.20, hs-CRP; SMD = 0.96; 95% CI: 0.64–1.28, IL-6; SMD = 2.68; 95% CI: 0.95–4.41, TNF-a; SMD = 0.50; 95% CI: 0.24–0.75, RDW; SMD = 0.56; 95% CI: 0.26–0.87). The main limitations inherent in this analysis are small case-control studies of moderate quality and high statistical heterogeneity. Our findings underscore that inflammatory dysregulation is implicated in coronary artery ectasia and merits further investigation.

Association of systemic immune-inflammation index (SII) with presence of isolated coronary artery ectasia. ARCHIVES OF MEDICAL SCIENCES. ATHEROSCLEROTIC DISEASES 2021; 6:e152-e157. [PMID: 34703943 PMCID: PMC8525247 DOI: 10.5114/amsad.2021.109253] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Accepted: 07/21/2021] [Indexed: 01/02/2023]
Abstract
Introduction The systemic immune-inflammation index (SII) has been developed based on the calculation of N×P/L (N, P and L represent neutrophil count, platelet count and lymphocyte count, respectively), and it is widely used as a marker of inflammation and an indicator of cardiovascular outcomes in patients with coronary artery disease. We examined a possible association between SII and the presence of isolated coronary artery ectasia (CAE). Material and methods In this retrospective case-control study, a total of 4400 patients who underwent elective coronary angiography between June 2015 and July 2020 were retrospectively screened. Following the application of exclusion criteria, our study population consisted of 139 CAE patients and 141 age- and gender-matched subjects who proved to have normal coronary angiograms. Results The median value of SII was found to be statistically significantly higher in patients with CAE (p < 0.01). SII level ≥ 809 measured on admission had 48% sensitivity and 82% specificity in predicting isolated CAE in ROC curve analysis. In this ROC analysis, the predictive powers of neutrophil-to-lymphocyte ratio (NLR) and SII in determining the presence of ectasia were compared, and the predictive power of SII was significantly stronger than N/L ratio (p = 0.003). In the multivariate analysis, hyperlipidaemia (OR = 1.978, 95% CI: 1.168–3.349, p = 0.01), smoking (OR = 1.86, 95% CI: 1.090–3.127, p = 0.023) N/L ratio (OR = 1.192, 95% CI: (1.114–1.997, p = 0.07) and SII (OR = 1.002, 95% CI: 1.001–1.003, p < 0.01) were independent predictors of the presence of isolated CAE. Conclusions SII is a readily available clinical laboratory value that is associated with the presence of isolated CAE. Our findings may indicate a common pathophysiological mechanism between CAE and coronary artery disease.

Abstract
Coronary artery ectasia describes a local or diffuse dilatation of the epicardial coronary arteries. This review summarizes the molecular and cellular mechanisms involved in the pathogenesis of coronary artery ectasia. Better identification of the pathophysiologic steps will shed light into the clinical significance and may have direct implications for the management strategies of this disease. Additionally, understanding the underlying etiology may help to improve treatment modalities specific to coronary artery ectasia.

Abstract
OBJECTIVES Coronary artery ectasia (CAE) is defined as the dilation of at least one segment of the coronary arteries that reaches at least 1.5 times the size of a normal neighboring segment. It has been shown that left ventricular (LV) diastolic function is impaired in patients with CAE. Also, it has been shown that LV function is impaired in vitamin D-deficient subjects compared with vitamin D-sufficient subjects and vitamin D deficiency is prevalent in CAE patients. We hypothesized that LV function is impaired in patients with CAE so we evaluated longitudinal LV myocardial function by 2D speckle tracking echocardiography (2DSTE) in patients with CAE and vitamin D deficiency without significant coronary artery stenosis and compared the results with those of subjects with vitamin D deficiency and near-normal coronary arteries. METHODS Our study population comprised 21 consecutive patients with CAE and without significant coronary artery stenosis (<50%) and 31 control subjects with near-normal coronary arteries. All subjects had vitamin D deficiency. RESULTS All 2DSTE-derived indices of longitudinal LV function, comprised of the absolute values of systolic strain (14.0±2.7% vs 15.4±2.3%, P=.039), systolic strain rate (1.2±0.2/s vs 1.3±0.2/s, P=.015), early diastolic strain rate (1.1±0.3/s vs 1.3±0.3 s-1 , P=.030), and late diastolic strain rate (0.8±0.2/s vs 1±0.2/s, P=.005), were reduced in the patients with CAE and vitamin D deficiency. CONCLUSIONS The systolic and diastolic functions of the LV in the patients with CAE and vitamin D deficiency were impaired as evaluated by 2DSTE.

Abstract
Objective To determine whether neutrophil/lymphocyte ratio (NLR) differed between patients with isolated coronary artery disease (CAD), isolated coronary artery ectasia (CAE), coronary slow flow and normal coronary anatomy. Methods Patients who underwent coronary angiography were consecutively enrolled into one of four groups: CAD, coronary slow flow, CAE and normal coronary anatomy. Results The CAD (n = 40), coronary slow flow (n = 40), and CAE (n = 40) groups had similar NLRs (2.51 ± 0.7, 2.40 ± 0.8, 2.6 ± 0.6, respectively) that were significantly higher than patients with normal coronary anatomy (n = 40; NLR, 1.73 ± 0.7). Receiver operating characteristics demonstrated that with NLR > 2.12, specificity in predicting isolated CAD was 85% and sensitivity was 75%, with NLR > 2.22 specificity in predicting isolated CAE was 86% and sensitivity was 75%. With NLR > 1.92, specificity in predicting coronary slow flow was 89% and sensitivity was 75%. Multivariate logistic regression analyses identified NLR as an independent predictor of isolated CAE (β = −0.499, 95% CI −0.502, −0.178; P < 0.001), CAD (β = −0.426, 95% CI −1.321, −0.408; P < 0.001), and coronary slow flow (β = −0.430, 95% CI −0.811, −0.240; P = 0.001 Table 2). Conclusions NLR was higher in patients with CAD, coronary slow flow and CAE versus normal coronary anatomy. NLR may be an indicator of CAD, CAE and coronary slow flow.

Common Phenolic Metabolites of Flavonoids, but Not Their Unmetabolized Precursors, Reduce the Secretion of Vascular Cellular Adhesion Molecules by Human Endothelial Cells. J Nutr 2016; 146:465-73. [PMID: 26843586 PMCID: PMC4763483 DOI: 10.3945/jn.115.217943] [Citation(s) in RCA: 62] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2015] [Revised: 07/20/2015] [Accepted: 12/29/2015] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Flavonoids have been implicated in the prevention of cardiovascular disease; however, their mechanisms of action have yet to be elucidated, possibly because most previous in vitro studies have used supraphysiological concentrations of unmetabolized flavonoids, overlooking their more bioavailable phenolic metabolites. OBJECTIVE We aimed to explore the effects of phenolic metabolites and their precursor flavonoids at physiologically achievable concentrations, in isolation and combination, on soluble vascular cellular adhesion molecule-1 (sVCAM-1). METHOD Fourteen phenolic acid metabolites and 6 flavonoids were screened at 1 μM for their relative effects on sVCAM-1 secretion by human umbilical vein endothelial cells stimulated with tumor necrosis factor alpha (TNF-α). The active metabolites were further studied for their response at different concentrations (0.01 μM-100 μM), structure-activity relationships, and effect on vascular cellular adhesion molecule (VCAM)-1 mRNA expression. In addition, the additive activity of the metabolites and flavonoids was investigated by screening 25 unique mixtures at cumulative equimolar concentrations of 1 μM. RESULTS Of the 20 compounds screened at 1 μM, inhibition of sVCAM-1 secretion was elicited by 4 phenolic metabolites, of which protocatechuic acid (PCA) was the most active (-17.2%, P = 0.05). Investigations into their responses at different concentrations showed that PCA significantly reduced sVCAM-1 15.2-36.5% between 1 and 100 μM, protocatechuic acid-3-sulfate and isovanillic acid reduced sVCAM-1 levels 12.2-54.7% between 10 and 100 μM, and protocatechuic acid-4-sulfate and isovanillic acid-3-glucuronide reduced sVCAM-1 secretion 27.6% and 42.8%, respectively, only at 100 μM. PCA demonstrated the strongest protein response and was therefore explored for its effect on VCAM-1 mRNA, where 78.4% inhibition was observed only after treatment with 100 μM PCA. Mixtures of the metabolites showed no activity toward sVCAM-1, suggesting no additive activity at 1 μM. CONCLUSIONS The present findings suggest that metabolism of flavonoids increases their vascular efficacy, resulting in a diversity of structures of varying bioactivity in human endothelial cells.

Abstract
BACKGROUND Kawasaki disease is an inflammatory condition. Neutrophil to lymphocyte ratio is a marker reflecting inflammation. AIMS The aim of the study is to evaluate usefulness of neutrophil to lymphocyte ratio in diagnosis of Kawasaki disease and in prediction of coronary artery lesions. STUDY DESIGN Retrospective cross-sectional study. METHODS Seventy-five children with Kawasaki disease and 66 controls were retrospectively enrolled. Their leukocyte, neutrophil, and lymphocyte counts were recorded. Abnormally distributed data were shown as median (interquartile range). Cases having coronary artery diameter two standard deviation above mean were diagnosed to have coronary artery lesions. RESULTS Median age of Kawasaki disease patients was 34 months. Twentyfive of those (33.33%) had incomplete Kawasaki disease and twenty-six (34.66%) had coronary artery lesions. Leukocyte [12.61 (6.09)×10(3)/µL vs. 8.48 (5.58)×10(3)/µL], neutrophil [6.73 (4.10) ×10(3)/µL vs. 4.62 (5.47)×10(3)/µL], and lymphocyte [4.04 (2.91)×10(3)/µL vs. 3.02 (2.57) ×10(3)/µL] counts were significantly higher in Kawasaki disease patients compared to controls (all p values <0.01). However, there was not significant difference between patients and controls regarding neutrophil to lymphocyte ratio [1.72 (1.22) vs. 1.71 (1.88)]. Findings of Kawasaki disease and incomplete Kawasaki disease cases did not differ, while comparison of patients with and without coronary artery lesions revealed significantly higher neutrophil to lymphocyte ratio values in former group [2.02 (1.63) vs. 1.50 (1.28), p=0.01]. The cut-off neutrophil to lymphocyte ratio value for prediction of coronary artery lesions was determined as 1.32. CONCLUSION Neutrophil to lymphocyte ratio values in Kawasaki patients with coronary lesions were significantly higher than the ones without and values greater than 1.32 were useful in prediction of coronary lesions.

[PMID: 25278983 PMCID: PMC4180607 DOI: 10.4070/kcj.2014.44.5.307] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2014] [Revised: 07/15/2014] [Accepted: 08/04/2014] [Indexed: 01/14/2023] Open
Abstract
Background and Objectives Coronary artery ectasia (CAE) is an angiographic finding characterized by dilation of an arterial segment with a diameter at least 1.5 times that of its adjacent normal coronary artery. Fragmented QRS (fQRS) complexes are electrocardiographic signals which reflect altered ventricular conduction around regions of a myocardial scar and/or ischaemia. In the present study, we aimed to evaluate the presence of fQRS in patients with CAE. Subjects and Methods The study population included 100 patients with isolated CAE without coronary artery disease (CAD) and 80 angiographically normal controls. fQRS was defined as the presence of an additional R wave or notching of R or S wave or the presence of fragmentation in two contiguous leads corresponding to a major coronary artery territory. Results The two groups were similar in terms of age, sex, hypertension, dyslipidemia, and family history of CAD. The presence of fQRS was significantly (p<0.05) higher in the CAE group than that in the normal coronary artery group (29% vs. 6.2%, p=0.008). Isolated CAE were detected most commonly in the right coronary artery (61%), followed by left anterior descending artery (52%), left circumflex artery (36%), and left main artery (9%). Multivariate stepwise logistic regression analysis showed that CAE {odds ratio (OR) 1.412; 95% confidence interval (CI) 1.085-1.541; p=0.003} and diabetes (OR 1.310; 95% CI 1.025-1.482; p=0.041) were independently associated with fQRS. Conclusion The presence of fragmented QRS associated with increased risk for arrhythmias and cardiovascular mortality was significantly higher in patients with CAE than in patient with normal coronary artery. Further studies are needed to determine whether the presence of fragmented QRS is a possible new risk factor for patients with CAE.

Abstract
The exact mechanisms underlying coronary artery ectasia (CAE) remain uncertain. This study aims to investigate whether and how inflammatory mediators play a role in the pathogenesis of CAE. The data sources of this study were located by literature searches on MEDLINE, Highwire Press and Google search engine for the year range 2000-2013. The most sensitive of the four types of plasma inflammatory mediators were cell adhesion molecules and systemic inflammatory markers followed by cytokines, while proteolytic substances were the least sensitive indicators of CAE. Hypersensitive C-reaction protein, homocysteine, intercellular adhesion molecule 1, vascular cell adhesion molecule 1, matrix metalloproteinase-9, tissue inhibitor of metalloproteinase-2, vascular endothelial growth factor and neopterin levels were significantly higher in CAE and coronary artery disease (CAD) patients than in controls without CAE. The percentage of granulocytes was higher in CAE, in comparison with individuals with normal coronary arteries. Polymerase chain reaction determination of angiotensin converting enzyme genotypes showed that the DD genotype was more prevalent in CAE patients than in CAD patients, while prevalence of the I allele was higher in CAD than in CAE patients. CAE is more a result of inflammatory processes than of extracellular matrix degradation, as demonstrated by investigations of plasma inflammatory mediators, activation markers and angiotensin converting enzyme genotypes. Contemporary theories are unable to explain CAE's predilection for the right coronary artery or the occurrence of multi-vessel and multi-segment involvement.

Predictive value of neutrophil to lymphocyte ratio for the presence of coronary artery ectasia in patients with aortic aneurysms. INTERNATIONAL JOURNAL OF CARDIOLOGY. HEART & VESSELS 2014; 4:30-34. [PMID: 29450182 PMCID: PMC5801477 DOI: 10.1016/j.ijchv.2014.08.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/27/2014] [Revised: 08/05/2014] [Accepted: 08/10/2014] [Indexed: 12/13/2022]
Abstract
Background Both aortic aneurysms and coronary artery ectasia (CAE) frequently coexist and are associated with more pronounced inflammation. Neutrophil to lymphocyte ratio (NL ratio) is widely used as a marker of inflammation. However, relation between CAE and NL ratio in patients with aortic aneurysms is not fully understood. This study was undertaken to assess relation between CAE and NL ratio in patients with aortic aneurysms. Methods This study consisted of 93 consecutive patients with aortic aneurysms (AA group) and 79 patients without aortic aneurysms who had angiographically normal coronary arteries as the control group. Moreover, patients with aortic aneurysms were classified into two groups based on the presence of CAE; CAE (+) group (n = 44) and CAE (−) group (n = 49). We compared blood chemical parameters in both groups. Results In the AA group, 44 patients (47.3%) had CAE. The AA group had a significantly higher NL ratio than the control group (2.93 ± 1.43 vs. 2.45 ± 1.05, p = 0.027). Furthermore, the CAE (+) group had a significantly higher NL ratio than the CAE (−) group (3.39 ± 1.67 vs. 2.52 ± 1.04, p < 0.01). Multivariate logistic regression analysis revealed that the high NL ratio was an independent predictor for CAE in patients with aortic aneurysms (odds ratio 1.76, 95% confidence interval 1.24–2.69, p = 0.001). Conclusions Patients with aortic aneurysms had a significantly higher NL ratio than those without aortic aneurysms. Furthermore, the NL ratio might predict the presence of CAE in patients with aortic aneurysms.

Abstract
AIM To evaluate possible links between coronary flow anomalies, inflammatory activation and coronary artery ectasia (CAE). METHODS Fourteen consecutive patients with CAE diagnosed at coronary angiography were enrolled in the study and compared with 17 patients with coronary atherosclerosis without CAE and 15 controls with normal coronary angiography. All patients underwent blood assay with evaluation of circulating levels of interleukin (IL)-1b, IL-2, IL-8, IL-10 and tumor-necrosis-factor(TNF)-α. The number of coronary segments showing CAE at coronary angiography, the Markis class, and coronary flow assessed with TIMI frame count (TFC) were also assessed. RESULTS Subjects with CAE showed higher levels of IL-1b, TNF-α, and IL-10 (p<0.05). The number of coronary segments showing CAE was related to TFC both in left anterior descending (LAD) coronary artery (p<0.01) and in right coronary artery (RCA) (p<0.001), and to circulating levels of IL-1b and IL-10 (p<0.01). TFC on LAD (p<0.05) and on RCA (p<0.001), circulating IL-1b levels (p<0.01), IL-8 (p<0.05), and IL-10 (p<0.01) were proportionally increased comparing controls, subjects with coronary atherosclerosis without CAE, and with decreasing Markis class. In subjects with CAE involving LAD, TFC on LAD was related to IL-8 and TNF-α levels (p<0.05); subjects with IL-1b levels above median showed higher TFC values on LAD (p<0.01), CONCLUSIONS: In subjects with CAE, the extension of disease is related to the impairment of coronary circulation and to inflammatory activation. The inflammatory response is also related to an impaired coronary circulation.

Abstract
We aimed to investigate the association between the neutrophil-lymphocyte ratio (NLR) and coronary artery ectasia (CAE). The study included 198 patients who had undergone coronary angiography for suspected coronary artery disease (CAD). The patients were divided into the following 4 groups: group 1, 44 patients with normal coronary arteries; group 2, 61 patients with CAD; group 3, 40 patients with isolated CAE; and group 4, 53 patients with CAE coexisting with CAD. Neutrophil-lymphocyte ratio was significantly lower in group 1 than the other groups and significantly higher in group 4. Patients in group 1 had significantly lower neutrophil counts and significantly higher lymphocyte counts than the patients in group 4. The isolated CAE and CAD groups were similar in terms of NLR, neutrophil count, and lymphocyte count. In addition, we found significant positive correlations between presence of ectasia, number of ectatic vessels, and NLR. Our findings provide additional evidence for the role of NLR in CAE.

Abstract
Objectives: Coronary artery ectasia (CAE) is characterized by an abnormal dilatation of the coronary arteries. Red cell distribution width (RDW) is a measure of heterogeneity in the size of red blood cell. In this study, we aimed to investigate RDW levels in patients with CAE. Methods: The study population included 54 patients with CAE (28 males; mean age, 59 ± 12) and 40 individuals comprising the control group who had normal coronary arteries (17 males; mean age, 56 ± 10). Admission RDW was measured as part of the automated complete blood count. Results: The RDW was significantly higher in the CAE group than the control ( P < .001). Also, high-sensitive C-reactive protein (hs-CRP) levels in patients with CAE were significantly higher as compared with controls ( P < .001). Conclusion: This study demonstrates that RDW and hs-CRP were higher in the CAE group compared with the control group. These results show that RDW is a reliable, simple, and inexpensive marker for patients with CAE.

BACKGROUND Over the past 10 years, the use of saliva as a diagnostic fluid has gained attention and has become a translational research success story. Some of the current nanotechnologies have been demonstrated to have the analytical sensitivity required for the use of saliva as a diagnostic medium to detect and predict disease progression. However, these technologies have not yet been integrated into current clinical practice and work flow. CONTENT As a diagnostic fluid, saliva offers advantages over serum because it can be collected noninvasively by individuals with modest training, and it offers a cost-effective approach for the screening of large populations. Gland-specific saliva can also be used for diagnosis of pathology specific to one of the major salivary glands. There is minimal risk of contracting infections during saliva collection, and saliva can be used in clinically challenging situations, such as obtaining samples from children or handicapped or anxious patients, in whom blood sampling could be a difficult act to perform. In this review we highlight the production of and secretion of saliva, the salivary proteome, transportation of biomolecules from blood capillaries to salivary glands, and the diagnostic potential of saliva for use in detection of cardiovascular disease and oral and breast cancers. We also highlight the barriers to application of saliva testing and its advancement in clinical settings. SUMMARY Saliva has the potential to become a first-line diagnostic sample of choice owing to the advancements in detection technologies coupled with combinations of biomolecules with clinical relevance.

Further increase in the expression of activation markers on monocyte-derived dendritic cells in coronary artery disease patients with ectasia compared to patients with coronary artery disease alone. Mediators Inflamm 2010; 2010:748919. [PMID: 20628522 PMCID: PMC2902079 DOI: 10.1155/2010/748919] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2010] [Revised: 04/12/2010] [Accepted: 04/27/2010] [Indexed: 12/13/2022] Open
Abstract
Background. Coronary artery ectasia (CAE) is defined as localized or diffuse dilation of the coronary arteries. There are scarce data about the role of dendritic cells in CAE development. In this study we investigated the activation markers on the surface of monocyte-derived dendritic cells (mDCs) in coronary artery disease (CAD) patients with or without CAE.
Method. The study consisted of 6 patients who had obstructive CAD with CAE, 6 CAD patients without CAE and 6 subjects with angiographically normal coronary arteries. mDCs were cultivated from peripheral blood monocytes. Surface activation markers were detected by flow cytometry.
Results. CAD patients with CAE were detected to have significantly higher mean fluorescence intensities of CD11b, CD11c, CD54 , CD83, CD86 and MHC Class II molecules on mDCs in comparison to CAD patients without CAE and normal controls (P < .001 for all). A significant positive correlation was found between the number of vessels with CAE and the levels of CD11c, CD86, and MHC Class II molecules.
Conclusion. mDCs display an increased cell surface concentration of activation molecules in CAD patients with CAE compared to patients with CAD alone. DC activation may play an important role for CAE development in patients with CAD.
