Relation of inflammatory chemokines to insulin resistance and hypoadiponectinemia in coronary artery disease patients
2009
Although many studies have shown that the metabolic syndrome (MS) and type 2 diabetes mellitus (T2DM) both are associated with chronic inflammatory state and are risk factors for coronary artery disease (CAD), it is still unclear which condition is a more important contributor to the increased production of inflammatory chemokines. The purpose of this study was to assess monocyte chemoattractant protein-1 (MCP-1) and interleukin-8 (IL-8) levels and their association with insulin resistance and adiponectin concentrations in CAD patients, who were categorized as having T2DM, MS, or neither.CAD male patients were categorized into three groups: 24 non-obese patients with T2DM (D), 24 obese pati…
Visceral adiposity index is associated with insulin sensitivity and adipocytokine levels in newly diagnosed acromegalic patients.
2012
Context: The visceral adiposity index (VAI) has proved to be a marker of visceral adipose dysfunction, strongly associated with insulin sensitivity in both the general and specific populations of patients at metabolic risk. Objective: The objective of the study was to test VAI as a useful tool to assess early metabolic risk in acromegaly. Patients: Twenty-four newly diagnosed acromegalic patients (11 women and 13 men, aged 54.9 ± 13.6 yr) were grouped into those with normal (group A, n = 13, 54.2%) and those with high VAI (group B, n = 11, 45.8%). Outcome Measures: Glucose, hemoglobin A1c, nadir and area under the curve (AUC) of GH (AUCGH) during the oral glucose tolerance test, AUCCpeptide…
Urinary adiponectin excretion rises with increasing albuminuria in type 1 diabetes
2013
Urinary adiponectin (u-adiponectin) excretion has been suggested to reflect early glomerular damage. Inspired by this, we studied the levels of u-adiponectin in type 1 diabetic patients with different levels of urinary albumin excretion (UAE).U-adiponectin was analysed by ELISA in type 1 diabetic patients: Fifty-eight with normoalbuminuria (30mg albumin/24h), 43 with persistent microalbuminuria (30-300mg/24h) and 44 with persistent macroalbuminuria (300mg/24h). For comparison, a control group of 55 healthy individuals was included.U-adiponectin increased with increasing levels of UAE (p0.01). U-adiponectin median (interquartile range): Normoalbuminuria 0.38 (0.14-1.31), microalbuminuria 1.1…
Plasma resistin levels are associated with homocysteine, endothelial activation, and nitrosative stress in obese youths.
2013
To evaluate whether serum resistin levels are related to cardiovascular risk in obese children.Cross-sectional study of 110 children (40 normal weight and 70 severely obese). Clinical and biochemical parameters, including lipid profile, fasting glucose and insulin, and homocysteine, were determined. The levels of adipokines (adiponectin, leptin, and resistin), markers of inflammation (high-sensitivity C-reactive protein (hs-CRP)), endothelial activation (serum concentrations of soluble intercellular and vascular cellular adhesion molecule-1 (sICAM-1, sVCAM-1)), and oxidative/nitrosative stress (malondialdehyde and urinary nitrate/nitrite) were measured.A partial correlation adjusted by gend…
Inflammation status of healthy young men: initial and specific responses to resistance training
2017
Our primary aim was to study the effects of a 4-week preparatory resistance-training (RT) period followed by 12 weeks of 2 specific RT protocols (either hypertrophic-strength (HS) or strength-hypertrophy-power training) on inflammation markers and the possible relationship of the changes in abdominal fat and lean mass to the changes in inflammation status. A total of 82 healthy men were included in the study. Maximal concentric leg press strength (1-repetition maximum), total body lean mass, total body and abdominal fat mass, circulating high-sensitivity C-reactive protein, interleukin-6, interleukin-1 receptor antagonist (IL-1ra), monocyte chemoattractant protein 1 (MCP-1), and selected a…
Diabetic foot syndrome as a possible cardiovascular marker in diabetic patients
2015
Diabetic foot ulcerations have been extensively reported as vascular complications of diabetes mellitus associated with a high degree of morbidity and mortality; in fact, some authors showed a higher prevalence of major, previous and new-onset, cardiovascular, and cerebrovascular events in diabetic patients with foot ulcers than in those without these complications. This is consistent with the fact that in diabetes there is a complex interplay of several variables with inflammatory metabolic disorders and their effect on the cardiovascular system that could explain previous reports of high morbidity and mortality rates in diabetic patients with amputations. Involvement of inflammatory marke…
Pioglitazone in addition to metformin improves erythrocyte deformability in patients with Type 2 diabetes mellitus
2010
The aim of the present study was to compare the effect of PIO (pioglitazone) or GLIM (glimepiride) on erythrocyte deformability in T2DM (Type 2 diabetes mellitus). The study covered 23 metformin-treated T2DM patients with an HbA1c (glycated haemoglobin) >6.5%. Patients were randomized to receive either PIO (15 mg, twice a day) or GLIM (1 mg, twice a day) in combination with metformin (850 mg, twice a day) for 6 months. Blood samples were taken for the measurement of fasting glucose, HbA1c, fasting insulin, intact proinsulin, adiponectin and Hct (haematocrit). In addition, the erythrocyte EI (elongation index) was measured using laser diffractoscopy. Both treatments significantly impr…
Intra-renal hemodynamics and carotid intima-media thickness in the metabolic syndrome.
2009
Aims: Metabolic syndrome (MetS) is associated with increased cardiovascular risk. We hypothesize that early vascular changes are already present at the time of diagnosis of MetS. The relationship of different measures of early vascular impairment with body fat distribution and the natural progression of MetS was examined in newly diagnosed subjects non-pharmacologically treated. Methods: 246 consecutively enrolled subjects were categorized according to the presence of MetS and type 2 diabetes (T2D). Intra-renal Doppler flow was used to ascertain resistive (RI) and pulsatility (PI) indices as markers of vascular resistance. Carotid intima-media thick- ness (IMT), cutis-rectis (CR) and rectis…
Increasing adiposity in normal ovulatory women affects adipocytokine expression in subcutaneous and visceral abdominal fat
2008
Abstract Objective To determine which adipocytokines are differentially expressed as a function of body mass index (BMI), to compare expression of adipocytokines in abdominal subcutaneous and omental fat, and to correlate these findings with serum levels, BMI, and parameters of insulin resistance. Methods Serum and subcutaneous (sc) and omental (om) tissue were obtained from lean and obese ovulatory women undergoing gynecologic surgery. We determined adipocytokine expression in sc versus om abdominal fat and related this to increasing BMI. Results Serum leptin was higher and adiponectin lower in overweight subjects. Adipocytokines had higher expression in sc abdominal versus om adipose tiss…
Long-term consequences of polycystic ovary syndrome on cardiovascular risk
2009
Most available data suggest that the prevalence of cardiovascular diseases in women with polycystic ovary syndrome (PCOS) is smaller than expected based on risk calculations during fertile years; therefore, more studies are needed on long-term cardiovascular consequences. Evidence is accumulating that postmenopausal women with PCOS have an increased risk of cerebrovascular events and cardiovascular morbidity. These events are partially related to persisting hyperandrogenism but are mostly correlated with excessive body weight (mainly visceral obesity); this suggests that our best long-term strategy is to ensure that women with PCOS are informed about their high risk for metabolic and cardio…
