          Abstract

          Objetivo: Determinar las concentraciones plasmáticas de factor de necrosis tumoral alfa (FNT-alfa) en mujeres obesas y no obesas con diagnóstico de síndrome de ovarios poliquísticos (SOPQ). Diseño: Estudio de casos y controles. Participantes: Mujeres con diagnóstico de SOPQ y controles sanas de edades similares, con menstruaciones regulares y ovarios normales por ecografía. Métodos: Las participantes fueron divididas en cuatro grupos (grupo A: SOPQ obesas; grupo B: SOPQ no obesas; grupo C: controles obesas; y grupo D: controles no obesas), de acuerdo al índice de masa corporal (obesas > 30 kg/m2 y no obesas < 25 kg/ m2). Principales medidas de resultados: Concentraciones de lutoprina, folitropina, androstendiona, testosterona, globulina fijadora de hormonas sexuales, glucosa sérica, insulina y FNT-alfa. Resultados: Las mujeres con SOPQ obesas y no obesas presentaron concentra ciones más elevadas de hormonas sexuales e insulina comparado con el grupo control de obesas y no obesas respectivamente (p < 0,0001). Se observó que las mujeres con SOPQ tuvieron concentraciones significativamente más altas de FNT-alfa (grupo A: 6,6 +/- 1,2 pg/ mL y grupo B: 4,0 +/- 0,7 pg/mL) comparado con los controles (grupo C: 4,4 +/- 1,3 pg/mL) y grupo D (2,1 +/- 0,4 pg/dL; p < 0,0001). Se observó que las concentraciones de FNT-alfa presentaban correlación positiva y significativa con los valores de glicemia e insulina en ayunas en las mujeres con SOPQ (p < 0,0001). Conclusión: Se ha hallado diferencias significativas en las concentraciones plasmáticas del FNT-alfa entre las mujeres con SOPQ obesas y no obesas respecto a los controles normales.

          Objective: To determine plasma concentration of tumor necrosis factor alpha (TNF-alpha) in obese and non-obese women with polycystic ovary syndrome (PCOS). Design: Case control study. Participants: Women with diagnosis of PCOS and age-matched healthy controls, the latter with regular periods and normal ovaries according to ultrasound. Interventions: Participants were divided in four groups (group A: PCOS and obese; group B: PCOS and nonobese; group C: obese controls; and group D: non-obese controls) according to body mass index (obese > 30 kg/m2 y and non-obese < 25 kg/m2). Main outcome results: Concentrations of luteinizing hormone, follicle-stimulating hormone, androstenodione, testosterone, sex hormone-binding globulin, serum glucose, insulin and TNF-alpha. Results: Obese and non-obese women with PCOS had higher luteinizing hormone, follicle stimulating hormone, androstenodione. testosterone, and insulin levels compared to women in the obese and non-obese control group, respectively (p < 0.0001). Women with PCOS had a significantly higher TNF-alpha plasma concentration (group A 6.6 +/-1.2 pg/mL and group B: 4.0 +/-0.7 pg/mL) as compared with controls (group C: 4.4 +/- 1.3 pg/mL and group D 2.1 +/- 0.4 pg/dL; p < 0.0001). TNF-alpha concentrations presented a positive and significant correlation with fasting glycaemia and insulin in women with PCOS (p < 0.0001). Conclusion: There were significant differences in plasma TNF-alpha concentrations between obese and non-obese women as compared with polycystic ovary syndrome and normal controls.

          High-molecular-weight adiponectin is selectively reduced in women with polycystic ovary syndrome independent of body mass index and severity of insulin resistance.

          High-molecular-weight (HMW) adiponectin contributes to insulin resistance (IR), which is closely associated with the pathophysiology of polycystic ovary syndrome (PCOS). Abnormalities in adipocyte function have been identified in PCOS and potentially contribute to lower adiponectin concentrations. Our objective was to determine which variables in plasma and adipose tissue influence HMW adiponectin in a well characterized cohort of women with PCOS. This was a cross-sectional study. A teaching hospital. Women with PCOS (n = 98) and body mass index (BMI)-matched controls (n = 103) (including 68 age-, BMI-, and IR-matched pairs). A standard 75-g oral glucose tolerance test was performed for each participant. Subcutaneous adipose tissue samples were taken by needle biopsy for a subset of PCOS women (n = 9) and controls (n = 8). Serum levels of HMW adiponectin and their relation to indices of insulin sensitivity, body composition, and circulating androgens as well as adipose tissue expression levels of ADIPOQ, TNFalpha, PPARgamma, and AR were assessed. HMW adiponectin was significantly lower in women with PCOS compared with both BMI- and BMI- and IR-matched controls (P = 0.009 and P = 0.027, respectively). Although BMI and IR were the main predictors of HMW adiponectin, an interaction between waist to hip ratio and plasma testosterone contributed to its variance (P = 0.026). Adipose tissue gene expression analysis demonstrated that AR and TNFalpha (P = 0.008 and P = 0.035, respectively) but not ADIPOQ mRNA levels were increased in PCOS compared with controls. HMW adiponectin is selectively reduced in women with PCOS, independent of BMI and IR. Gene expression analysis suggests that posttranscriptional/translational modification contributes to reduced HMW adiponectin in PCOS.

            Consolidated and emerging inflammatory markers in coronary artery disease.

            Coronary artery disease is an event of atherosclerosis characterized by a chronic vascular inflammation. Risk factors like obesity, diabetes mellitus, hypertension, smoking, hypercholesterolemia and positive family history sometimes are not sufficiently adequate to the enhancement of cardiovascular risk assessment. In the past years numerous biomarkers, like C reactive protein, cytokines and adhesion molecules, have been observed to be related to adverse cardiovascular prognosis. Recently, several studies found an association among inflammatory biomarkers and cardiovascular diseases suggesting their utility to identify the risk of an acute ischemic event and the detection of vulnerable plaques. The emerging inflammatory markers are well divided for diagnosis and prognosis and plaque instability of coronary artery disease. Some of them, the lectin-like oxidized low density lipoprotein receptor-1 can be important both in diagnosis and in the evaluation of plaque instability, other are inserted in the above reported classification. The emerging inflammatory markers in acute-phase include amyloid A, fibrinogen and pentraxin 3 while myeloperoxidase, myeloid-related protein 8/14 and pregnancy-associated plasma protein-A are recognize markers of plaque instability. Lastly, some studies demonstrated that circulating miRNAs are involved in coronary artery disease, acute myocardial infarction and heart failure.

              Early Biomarkers of Subclinical Atherosclerosis in Obese Adolescent Girls with Polycystic Ovary Syndrome.

              Because in obese youth, pulse wave velocity (PWV), an early cardiovascular disease marker, is elevated, we tested if obese girls with polycystic ovary syndrome (OB-PCOS) have higher PWV and carotid intima-media thickness (cIMT) compared with obese girls without PCOS (OB-non-PCOS) and normal-weight girls without PCOS (NW-non-PCOS) and whether PWV and cIMT correlate with inflammatory and circulating endothelial function biomarkers.
