Resumo: OBJECTIVES: Inflammatory molecules play a role in the development of atherosclerosis, which is the primary origin of cardiovascular disorders. However, to the best of our knowledge, no study has attempted to investigate the relationship between these circulating molecules and the prediction of cardiovascular risk. The present study aimed to investigate the relationships of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 serum concentrations with the extent of coronary lesions. METHODS: Seventy-four individuals who were undergoing coronary angiography for the first time for diagnostic purposes were enrolled in this study. The extent of the coronary lesion was assessed using the Friesinger Index, and subjects were classified into four groups: no lesions, minor lesions, intermediate lesions and major lesions. Serum biochemical parameters and serum concentrations of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 were analyzed. RESULTS: The vascular cell adhesion molecule-1 concentration was higher than 876 ng/mL in individuals with intermediate and major lesions (p<0.001 and p=0.020, respectively). Moreover, logistic regression analysis showed that these patients had an increased risk of having an intermediate lesion (p=0.007). Interestingly, all individuals with major lesions had vascular cell adhesion molecule-1 concentrations higher than 876 ng/mL. No association was found between the concentrations of the other proteins and the Friesinger Index. CONCLUSIONS: Serum vascular cell adhesion molecule-1 may be associated with the extent of coronary lesions. Moreover, it may represent an alternative to improve the cardiovascular risk classification in patients without acute coronary syndrome.

Resumo: Abstract INTRODUCTION: Dengue is an important mosquito-borne disease in tropical and subtropical regions. Adhesion molecules have not been systematically characterized in the renal tissue of patients with severe dengue (SD). The objective of this study was to detect viral antigens in samples from patients that evolved with SD, correlating with the expression of ICAM-1, VCAM-1, VE-cadherin, and E-selectin to contribute to a better understanding of the pathophysiology of SD. METHODS: Kidney specimens from patients with SD were selected according to clinical and laboratorial data and submitted to histological and immunohistochemistry analysis. A semiquantitative evaluation was performed considering positive immunostaining in 20 glomeruli. RESULTS: Viral antigens were mainly detected in distal tubules. The intense immunostaining of VCAM-1 and ICAM-1 was observed. The expression of E-selectin was discrete, and VE-cadherin expression varied from mild to moderate. VCAM-1 was slightly intense in the glomerular capsule; the expression of ICAM-1 was diffuse. E-selectin was diffuse, and VE-cadherin varied from mild to moderate. The most frequent histological findings were glomerular congestion, mild glomerulitis, acute renal injury, and glomerular atrophy. CONCLUSIONS: The results appear to demonstrate an imbalance between vascular endothelial permeability regulating events in renal lesions in SD. The increase in the expression of ICAM-1 and VCAM-1 is an in-situ indicator of higher permeability with a consequent influx of cells favoring the inflammation of the endothelium. These molecules are important in the pathophysiology of the disease and provide the possibility of developing new markers for the evaluation, clinical follow-up, and therapeutic response of patients with SD.

Idioma: en.
Resumo: SUMMARY OBJECTIVE This study aimed to investigate the effect of propylthiouracil treatment on adhesion molecules in patients with subclinical hyperthyroidism. METHODS In this study, a total of 168 patients diagnosed with subclinical hyperthyroidism were treated with propylthiouracil for one year. The levels of adhesion molecules, consisting of sICAM-1, sVCAM-1, and sE-Selectin, before and after the treatment were measured and compared. These results were compared with the levels of 148 healthy controls who received a placebo. RESULTS sICAM-1 levels were significantly higher in subclinical hyperthyroidism patients than in healthy controls (*pa=0.000). sICAM-1 levels were significantly decreased after the treatment (**pb=0.000). Despite this decrease in patients with subclinical hyperthyroidism, it did not decrease to the level of the control group. sVCAM-1 did not change before and after propylthiouracil treatment. The level of sE-selectin was similar to that of the pretreatment control group, but it did not have statistical significance, although it increased after the treatment (**pb=0.004). CONCLUSION The sICAM level was significantly higher than the pretreatment values and decreased after the propylthiouracil treatment. However, further studies are needed to reduce the risk of atherosclerosis and cancer in patients with subclinical hyperthyroidism.

RESUMO ANTECEDENTES O objetivo deste estudo foi investigar o efeito do tratamento com propiltiouracil nas moléculas de adesão em pacientes com hipertireoidismo subclínico. MÉTODOS Neste estudo, 168 pacientes diagnosticados com hipertireoidismo subclínico foram tratados com propiltiouracil por um ano. Os níveis de moléculas de adesão, especificamente sICAM-1, sVCAM-1 e sE-Selectina, antes e após o tratamento foram medidos e comparados. Esses resultados foram comparados com os níveis de 148 indivíduos saudáveis no grupo de controle que receberam um placebo. RESULTADOS Os níveis de sICAM-1 foram significativamente maiores em pacientes com hipertireoidismo subclínico do que nos controles saudáveis (*pa=0,000). Os níveis de sICAM-1 diminuíram significativamente após o tratamento (**pb=0,000). Apesar dessa diminuição em pacientes com hipertireoidismo subclínico, ela não diminuiu para o nível do grupo controle. O sVCAM-1 não se alterou antes e após o tratamento com propiltiouracil. O nível de sE-Selectina foi semelhante ao do grupo de controle pré-tratamento, mas não apresentou significância estatística, embora tenha aumentado após o tratamento (** pb = 0,004). CONCLUSÃO O nível de sICAM foi significativamente superior aos valores pré-tratamento e diminuiu após o tratamento com propilciliouracil. No entanto, mais estudos são necessários para reduzir o risco de aterosclerose e câncer em pacientes com hipertireoidismo subclínico.

Título: Circulating E-selectin levels and insulin resistance are associated with early stages of atherosclerosis in nonfunctional adrenal incidentaloma
Fonte: Arch. endocrinol. metab. (Online);59(4):310-317, Aug. 2015. tab, ilus.
Idioma: en.
Resumo: Objective To evaluate circulating E-selectin levels in patients with nonfunctional adrenal incidentaloma (NFA) in relation to insulin resistance and early atherosclerosis.Subjects and methods A total of 40 patients with NFA (mean [SD] age: 55.6 [10.7] years; 70% were females) and 35 controls (mean [SD] age: 51.5 [8.1] years; 71.4% were females) selected from age-, gender- and body mass index (BMI)- matched healthy subjects were enrolled. Serum hsCRP, lipid profile, insulin levels and the homeostasis model assessment of insulin resistance (HOMA-IR) were evaluated. High-resolution B-mode ultrasonography was performed. Serum levels of E-selectin were evaluated by enzyme-linked immunosorbent assay.Results Patients with NFA had significantly higher values for E-selectin (14.9 (4.8) vs. 12.2 (4.1) ng/mL, p < 0.01) and CIMT (0.6 (0.1) vs. 0.5 (0.1) mm, p < 0.05) than controls. Serum E-selectin levels showed a statistically significant association with hsCRP (r = 0.751, p < 0.001), HOMA-IR (r = 0.575, p < 0.001) and CIMT (r = 0.762, p < 0.001). CIMT (Carotid intima media thickness) was increased in patients with NFA patients with NFA were more insulin resistant than controls and statistically significant relationship was found between size of tumor and HOMA-IR (r = 0.361, p < 0.001).Conclusion In conclusion, based on significantly higher values for E-selectin, CIMT and HOMA-IR in patients with NFA than controls along with significant correlation of E-selectin levels to CIMT, HOMA-IR and hs-CRP, our findings seems to indicate an increased risk of early atherosclerosis and impaired endothelial function in NFA patients, particularly in case of insulin resistance.

Resumo: ABSTRACT Objective Our aim was to describe the distribution of selected biomarkers according to age and sex, adjusted for HOMA-IR and adiposity, in a subset of middle-aged individuals of Brazilian Longitudinal Study of Adult Health-ELSA without diabetes mellitus or CVD. Subjects and methods This cross-sectional study was conducted in 998 participants of the ELSA-Brasil without diabetes and/or cardiovascular disease. In addition to the traditional risk factors, several biomarkers concentrations were compared according to sex, age groups (35-44; 45-54 yrs) and HOMA-IR tertiles. Linear regression was used to examine independent associations of sex and age with selected novel biomarkers, adjusted for body adiposity and HOMA-IR. Results Fifty-five percent were women. Men had higher mean values of body mass index, waist circumference, blood pressure, plasma glucose, HOMA-IR, worse lipid profile and higher E-selectin and lower leptin concentrations than women; while women had higher levels of HDL-cholesterol and leptin than men. Mean values of waist circumference, systolic BP, plasma glucose and apolipoprotein B (Apo B) increased with age in both sexes. Leptin and E-selectin concentrations increased across HOMA-IR tertiles. Independent associations of Apo B with age were found only in male sex, while of leptin with body mass index and HOMA-IR, and of E-selectin with HOMA-IR in both sexes. Conclusions In conclusion, our data indicate age, sex, adiposity and, consequently, insulin resistance, influence circulating levels of Apo B, leptin and E-selectin, suggesting that those aspects should be taken into consideration when assessing these parameters for research or clinical purposes in individuals at relatively low cardiometabolic risk.

Resumo: Se investigó la relación entre los polimorfismos de E-selectina, la molécula de adhesión vascular-1 (VCAM1) y la molécula de adhesión intercelular-1 (ICAM1) con el perfil de lípidos y marcadores clínicos de inflamación en artritis reumatoide (AR). Se incluyeron 60 pacientes con AR clasificados de acuerdo a los criterios del American College of Rheumatology (ACR, 1987) y 60 controles clínicamente sanos (CCS), no relacionados entre sí, definidos como población de mestizos mexicanos. Los genotipos se caracterizaron por la técnica de PCR-RFLP. La velocidad de sedimentación globular (VSG), factor reumatoideo (FR), concentración de fibrinógeno (FB), proteína C reactiva (PCR) y perfil de lípidos, se realizaron por métodos convencionales. El análisis estadístico se efectuó con SPSS v10.0. La VSG correlacionó con PCR, FR, FB y cHDL, (r=0,507; 0,296; 0,475 y -0,308, respectivamente); PCR con FB (r=0,613), p<0,05. El alelo 1238G se asoció con FR y Apo-B; y el alelo 721A, con cHDL y cLDL (p<0,05). Los datos muestran que los niveles de FB, cHDL, y los alelos 721A de ICAM1 y 1238G de VCAM1 se asocian con los marcadores clínicos de inflamación. Existen diferencias entre la distribución de los polimorfismos en este estudio y las reportadas para población oriental, caucásica y turca.

The genotypes were characterized using the polymerase chain reaction-restriction fragment length polymorphisms (PCR-RFLP) technique. The ESR (erythrocyte sedimentation rate), RF (rheumatoid factor), fibrinogen (FB), C-reactive protein (CRP) and lipid profile were measured by routine methods. Statistical analysis was performed using SPSS v10.0. The significant Pearson´s correlations were: ESR with CRP, RF, FB and HDLc, (r=0.507, 0.296, 0.475, and -0.308, respectively); CRP with FB (r=0.613), p<0.05. The results showed an association with A allele of ICAM1 polymorphism and serum levels of HDLc and LDLc; and Apo-B and FR showed an association with C allele of VCAM1 polymorphism (p<0.05). Data shows that FB and HDLc levels, and ICAM1 polymorphism allele 721A and VCAM1 polymorphism allele 1238G are associated with clinical inflammation markers in RA. Our Mexican-mestizo population showed differences with many reports (from English, American, Turkish, Japanese, Chinese, Italian, and Korean populations).

Resumo: INTRODUÇÃO: Eventos vasculares e imunológicos são centrais na patogênese da granulomatose com poliangeíte (GPA). Moléculas de adesão celular tem papel fundamental no recrutamento de células inflamatórias do sangue para os tecidos. Diferentes leitos vasculares apresentam particularidades na expressão de moléculas de adesão celular explicando talvez parte da especificidade da GPA por determinados órgãos. A elevação no nível sérico de moléculas de adesão celular e aumento da expressão destas em amostras de biópsia renal já foram demonstrados em pacientes com vasculite ANCA associada. No entanto, o fenômeno ainda não foi estudado in situ no pulmão. OBJETIVO: O objetivo deste estudo foi analisar o padrão de expressão endotelial pulmonar de três moléculas de adesão celular na GPA, in situ: molécula de adesão intercelular 1 (ICAM-1), molécula e adesão vascular 1 (VCAM-1) e E-selectina. MÉTODOS: Examinou-se a expressão endotelial de ICAM-1, VCAM-1, E-selectina usando marcação imuno-histoquímica em secções de pulmão fixadas e parafinadas de lesões de GPA (n = 8 casos, 90 secções transversais de vasos analisados). Foram também analisados controles positivos: amostras de pulmão de doença intersticial associada à esclerodermia (SScl) (n = 8 casos, 96 secções transversais de vasos analisados) e controles negativos (n = 9 casos, 90 secções transversais de vasos analisados). A quantificação imuno-histoquímica foi realizada no aumento de 400x usando a técnica de point-counting. RESULTADOS: ICAM-1: A expressão endotelial mediana de ICAM-1 esteve aumentada de forma semelhante na GPA e na SScl (81% and 73%, respectivamente; p = 0.97). A comparação com o grupo controle (26.3%) revelou diferença estatisticamente significativa entre controle e GPA (p <0.001) quanto entre controle e SScl (p = 0.017). VCAM-1: A expressão mediana de VCAM-1 esteve significativamente aumentada na GPA se comparada a SScl (79.5% vs 41.4%; p = 0.012), no entanto, a expressão endotelial de VCAM-1 nos...

INTRODUCTION: Vascular and immunologic processes are central to the pathogenesis of granulomatosis with polyangiitis (GPA). Endothelial cellular adhesion molecules have a central role in recruiting leukocytes to sites of inflammation. Moreover, different vascular beds are phenotypically and functionally distinct with regard to expression of cellular adhesion molecules. They have been shown to be elevated in sera and in renal biopsies of patients with active ANCA-associated vasculitis. Despite of that, the expression of cellular adhesion molecules has not been studied in situ in the lungs. OBJECTIVE: Within this context, the aim of this study was to analyze the in situ pulmonary endothelial immunohistochemical pattern of expression of three cellular adhesion molecules in GPA: intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1) and E-selectin . METHODS: For such, we examined formalin-fixed, paraffin-embedded sections of lung lesions of GPA (n = 8 cases, 90 transverse sections of pulmonary vessels), negative controls which were obtained from autopsies ( n = 9 cases, 90 transverse sections of pulmonary vessels analyzed) and positive controls which were cases of interstitial lung disease associated with systemic sclerosis (SScl) (n = 8 cases, 96 transverse sections of pulmonary vessels). The quantification of the immunohistochemical staining was performed at x400 magnification using the technique of point-counting, previously described. RESULTS: ICAM-1: Median endothelial expression of ICAM-1 was similarly enhanced in GPA and SScl (81% and 73%, respectively; p = 0.97). When compared to controls (26.3%), both GPA (p <0.001) and SScl (p = 0.017) had significantly higher endothelial expression of ICAM-1. VCAM-1: Median endothelial expression of VCAM-1 was significantly enhanced in GPA when compared to SScl (79.5% vs 41.4%; p = 0.012), however the endothelial expression of VCAM-1 in the controls was also moderately enhanced (49.8%)...

Idioma: en.
Resumo: ObjectiveThere is a growing body of data supporting the association between diabetes and microcirculatory disfunction. We aimed to study e-selectin levels, and their associations with serum markers of inflammation and arterial stiffness in prediabetes and newly diagnosed diabetes patients in this study.Subjects and methodsSixty patients (25 females) with a newly established elevated fasting serum glucose [20 impaired fasting glucose (IFG), 20 impaired glucose tolerance (IGT), 20 newly diagnosed diabetes (T2DM)] and 17 healthy controls (13 females) were included in the study. Serum e-selectin and hs-CRP levels, and arterial stiffness parameters of the patients were studied.ResultsFasting serum glucose was the most important predictor of serum e-selectin levels. Pulse wave velocity and central aortic pressures were significantly higher in IFG, IGT and T2DM groups, compared to controls (p = 0.001, < 0.001, 0.013 and 0.015, 0.002, 0.009, respectively). The mean arterial pressure did not show any significant association with serum e-selectin and hs-CRP levels (β coefficient: 0.092, p = 0.358; and β coefficient: 0.189, p = 0.362, respectively).ConclusionPrediabetes patients have increasing e-selectin levels through the diagnosis of T2DM. E-selectin is associated with serum glucose levels. Prediabetic and newly diagnosed diabetics have higher arterial stiffness measurements. Serum e-selectin may be a good marker of endothelial inflammation and dysfunction increasing in parallel with serum glucose levels, predicting future cardiovascular events.

Resumo: Background: Circulatory power (CP) and ventilatory power (VP) are indices that have been used for the clinical evaluation of patients with heart failure; however, no study has evaluated these indices in patients with coronary artery disease (CAD) without heart failure. Objective: To characterize both indices in patients with CAD compared with healthy controls. Methods: Eighty-seven men [CAD group = 42 subjects and healthy control group (CG) = 45 subjects] aged 40–65 years were included. Cardiopulmonary exercise testing was performed on a treadmill and the following parameters were measured: 1) peak oxygen consumption (VO2), 2) peak heart rate (HR), 3) peak blood pressure (BP), 4) peak rate-pressure product (peak systolic HR x peak BP), 5) peak oxygen pulse (peak VO2/peak HR), 6) oxygen uptake efficiency (OUES), 7) carbon dioxide production efficiency (minute ventilation/carbon dioxide production slope), 8) CP (peak VO2 x peak systolic BP) and 9) VP (peak systolic BP/carbon dioxide production efficiency). Results: The CAD group had significantly lower values for peak VO2 (p < 0.001), peak HR (p < 0.001), peak systolic BP (p < 0.001), peak rate-pressure product (p < 0.001), peak oxygen pulse (p = 0.008), OUES (p < 0.001), CP (p < 0.001), and VP (p < 0.001) and significantly higher values for peak diastolic BP (p = 0.004) and carbon dioxide production efficiency (p < 0.001) compared with CG. Stepwise regression analysis showed that CP was influenced by group (R2 = 0.44, p < 0.001) and VP was influenced by both group and number of vessels with stenosis after treatment (interaction effects: R2 = 0.46, p < 0.001). Conclusion: The indices CP and VP were lower in men with CAD than healthy controls. .

Fundamento: Os índices da Potência Circulatória (PC) e Potência Ventilatória (PV) têm sido utilizados para avaliação clínica de pacientes com insuficiência cardíaca, mas nenhum estudo avaliou esses índices em pacientes com Doença Arterial Coronariana (DAC). Objetivo: Caracterizar ambos os índices em pacientes com DAC comparados a indivíduos saudáveis. Métodos: Oitenta e sete homens [grupo DAC = 42 sujeitos e, grupo controle (GC) = 45 sujeitos] com idade entre 45 e 65 anos foram incluídos. Um Teste de Exercício Cardiopulmonar (TECP) foi realizado em esteira e as seguintes variáveis foram obtidas: 1) consumo de oxigênio (VO2) pico; 2) Frequência Cardíaca (FC) pico; 3) Pressão Arterial (PA) pico; 4) duplo produto pico (PA sistólica pico x FC pico); 5) pulso de oxigênio pico (VO2 pico dividido pela FC pico); 6) eficiência ventilatória para o consumo de oxigênio (OUES); 7) eficiência ventilatória para a produção de dióxido de carbono (VE/VCO2 slope); 8) PC (VO2 pico x PA sistólica pico); e 9) PV (PA sistólica pico dividido pelo VE/VCO2 slope). Resultados: O grupo DAC apresentou valores significativamente menores das seguintes variáveis no pico do exercício: VO2 (p < 0,001), FC (p < 0,001), PA sistólica (p < 0,001), duplo produto (p < 0,001), pulso de oxigênio (p = 0,008), OUES (p < 0,001), PC (p < 0,001) e PV (p < 0,001), e valores significativamente maiores de PA diastólica (p = 0,004) e VE/VCO2 slope (p < 0,001) em relação ao GC. Uma análise de regressão pelo método stepwise mostrou que a PC foi influenciada pelo grupo (R2 = 0,44, p < 0,001) e a PV tanto pelo grupo quanto pelo número de vasos com estenose pós tratamento (efeito de interação: R2 = 0,46, p < 0,001). Conclusion: Os índices da PC e PV foram menores em homens com DAC comparados ao GC, podendo dessa forma ser utilizados na caracterização dessa população. .

Resumo: Deep venous thrombosis (DVT) is a common surgical complication in cancer patients and evidence that inflammation plays a role in the occurrence of DVT is increasing. We studied a population of cancer patients with abdominal malignancies with the aim of investigating whether the levels of circulating inflammatory cytokines were associated with postoperative DVT, and to determine the levels in DVT diagnoses. The serum levels of C-reactive protein (CRP), interleukins (IL)-6 and IL-10, nuclear transcription factor-κB (NF-κB) and E-selectin (E-Sel) were determined in 120 individuals, who were divided into 3 groups: healthy controls, patients with and patients without DVT after surgery for an abdominal malignancy. Data were analyzed by ANOVA, Dunnet's T3 test, chi-square test, and univariate and multivariate logistic regression as needed. The CRP, IL-6, NF-κB, and E-Sel levels in patients with DVT were significantly higher than those in the other groups (P<0.05). The IL-10 level was higher in patients with DVT than in controls but lower than in patients without DVT. Univariate analysis revealed that CRP, IL-6, NF-κB, and E-Sel were statistically associated with the risk of DVT (OR=1.98, P=0.002; OR=1.17, P=0.000; OR=1.03, P=0.042; and OR=1.38, P=0.003; respectively), whereas IL-10 had a protective effect (OR=0.94, P=0.011). Multivariate analysis showed that E-Sel was an independent risk factor (OR=1.41, P=0.000). Thus, this study indicated that an increased serum level of E-Sel was associated with increased DVT risk in postoperative patients with abdominal malignancy, indicating that E-Sel may be a useful predictor of diagnosis of DVT.
