OBJECTIVE To analyze the participation of fatty liver (FL) in the association of metabolic syndrome (MS) with type 2 diabetes and coronary artery calcification (CAC). RESEARCH DESIGN AND METHODS A total of 765 subjects (52% women) aged 30 to 75 years without clinical atherosclerosis were included in this study. MS was defined in accordance with the Adult(More)
BACKGROUND ABCA1 genetic variation is known to play a role in HDL-C levels and various studies have also implicated ABCA1 variation in cardiovascular risk. The functional ABCA1/R230C variant is frequent in the Mexican population and has been consistently associated with low HDL-C concentrations. Although it has been associated with other cardiovascular risk(More)
Little is known about qualitative abnormalities of high-density lipoproteins (HDL) in systemic lupus erythematosus (SLE). We studied distribution and composition of HDL subclasses in 30 premenopausal women with uncomplicated SLE, and 18 controls matched for age and sex. Plasma and HDL lipids were determined by colorimetric enzymatic assays, HDL size(More)
BACKGROUND Experimental studies have shown that high free fatty acid (FFA) and low adiponectin (ADIPO) levels are involved in the mechanisms by which adiposity promotes insulin resistance (IR). However, no previous clinical studies have simultaneously analysed the relative contribution of FFA and ADIPO levels on the relation of abdominal visceral fat (AVF)(More)
BACKGROUND The effect of ABCA1 genetic variation on HDL-C levels has been widely documented, although studies in children are scarce. We recently found a frequent non-synonymous ABCA1 variant (R230C) exclusive to populations with Native American ancestry, associated with low HDL-C levels and other metabolic traits in adults. METHODS We genotyped R230C(More)
We tested whether low high-density lipoprotein cholesterol (HDL-C) and/or high triglycerides are associated to abnormal HDL subclasses distribution and composition, and their relationships with fasting insulin and C-reactive protein (CRP). Four groups of adolescents were studied: group 1 (HDL-C< or =35 mg/dl+TG> or =150 mg/dl; n=16); group 2 (isolated(More)
BACKGROUND A growing body of evidence suggests that psychological stress is an independent cardiovascular risk factor. Obesity prevalence shows accelerating trends worldwide, and is known to be associated with a range of comorbidities and survival. The aim of this study was to assess the relationship between self-perceived psychological stress with(More)
OBJECTIVE We studied the effect of pioglitazone on insulin levels, inflammation markers, high-density lipoprotein (HDL) composition and subclasses distribution, in young women with uncomplicated systemic lupus erythematosus (SLE). METHODS This double-blind trial included 30 premenopausal women (30 ±8 years old) with SLE, who were randomized to(More)
BACKGROUND The association of subclinical hypothyroidism (SCH) with insulin resistance, metabolic syndrome (MS), and coronary atherosclerosis is uncertain. OBJECTIVE To investigate the role of increased intrahepatic fat in the association of SCH with insulin resistance, MS, and coronary atherosclerosis. DESIGN, PATIENTS, AND METHODS We conducted a(More)
In 69 statin-treated male coronary patients with low-density lipoprotein cholesterol at goal levels (<70 mg/dl), the investigators tested whether low high-density lipoprotein (HDL) cholesterol (<40 mg/dl) and high triglyceride (>150 mg/dl) are associated with dysfunctional HDL particles and abnormal insulin, adiponectin, C-reactive protein serum levels.(More)
