Visceral leishmaniasis is associated with marked changes in serum lipid profile.

Background: Infection is often accompanied by lipid profile alterations. The aim of this study was to evaluate the lipid profile changes in patients with visceral leishmaniasis (VL).

Materials And Methods: We included 15 patients [10 men, aged 50 (24-82) years old] with VL and 15 age- and sex-matched controls.

Differences in metabolic parameters and cardiovascular risk between American Diabetes Association and World Health Organization definition of impaired fasting glucose in European Caucasian subjects: a cross-sectional study.

Introduction: The American Diabetes Association (ADA) defines impaired fasting glucose (IFG) as fasting plasma glucose concentration of 100-125 mg/dl, whereas the World Health Organization (WHO) and the International Diabetes Federation (IDF) define IFG as fasting plasma glucose levels of 110-125 mg/dl. We identified differences in metabolic parameters and cardiovascular disease (CVD) risk according to the ADA or WHO/IDF definition of IFG.

Material And Methods: Healthy drug-naive Caucasian (Greek) subjects (n = 396; age 55 ±12 years) participated in this cross-sectional study.

Small high-density lipoprotein (HDL) subclasses are increased with decreased activity of HDL-associated phospholipase A₂ in subjects with prediabetes.

Alterations in high-density lipoprotein (HDL) subclass distribution, as well as in the activities of HDL-associated enzymes, have been associated with increased cardiovascular disease (CVD) risk. HDL subclass distribution and the activities of HDL-associated enzymes remain unknown in prediabetic patients, a condition also associated with increased CVD risk. The aim of the present study was to assess any differences in HDL subclass distribution (using polyacrylamide gel electrophoresis) and in activities of HDL-associated enzymes between prediabetic (impaired fasting glucose, IFG, n = 80) and non-prediabetic subjects (n = 105).

The relationship of vitamin D with non-traditional risk factors for cardiovascular disease in subjects with metabolic syndrome.

Introduction: Several studies implicate an inverse relationship between 25-hydroxy vitamin D (25(OH)Vit D) serum levels and metabolic syndrome (MetS). We sought to investigate a possible relationship between 25(OH)Vit D and emerging risk factors associated with MetS, such as small dense low-density lipoprotein cholesterol (sdLDL-C) concentration, lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) activity and high-sensitivity C-reactive protein (hsCRP) levels.

Material And Methods: We studied 110 consecutive otherwise healthy individuals.

High-dose intravenous immunoglobulin in the treatment of adult patients with bullous pemphigoid.

High-dose intravenous immunoglobulin (IVIg) has only been sporadically used in the treatment of bullous pemphigoid (BP), as it is suggested as an adjuvant to systemic corticosteroids in progressive disease or when life-threatening complications are of concern with other therapeutic interventions. The aim of the present study was to report our observations in the treatment of adult BP patients with IVIg, in association with a focused literature review. In our Department we identified five patients (4 women, 1 man) who had received IVIg for BP relatively early in the course of their disease.

The relationship between adiponectin, an adiponectin gene polymorphism, and high-density lipoprotein particle size: from the Mima study.

This study examined the association among serum adiponectin levels, a single nucleotide polymorphism (SNP) of the adiponectin gene, and the size of serum high-density lipoprotein (HDL) particles in a general population. A total of 275 subjects were examined as part of the community-based Mima study. Serum adiponectin levels were measured with an enzyme-linked immunosorbent assay.

Leptospirosis is associated with markedly increased triglycerides and small dense low-density lipoprotein and decreased high-density lipoprotein.

The objective of the present study was to evaluate the effects of acute infection with Leptospira interrogans on lipids, lipoproteins and associated enzymes. Fasting serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), apolipoproteins (apo) A-Ι, B, E, C-II, C-III and lipoprotein (a) [Lp(a)] were determined in patients with Leptospirosis on diagnosis and 4 months after recovery as well as in age- and sex-matched controls. Activities of cholesteryl-ester transfer protein (CETP) and lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) as well as paraoxonase 1 (PON1) hydrolysing activity and levels of cytokines were determined.

Ezetimibe treatment lowers indicators of oxidative stress in hypercholesterolemic subjects with high oxidative stress.

Ezetimibe effectively reduces low-density lipoprotein cholesterol (LDL-C). In this study, we tested the hypothesis that ezetimibe monotherapy may also decrease markers of oxidative stress in subjects with hypercholesterolemia. Subjects with hypercholesterolemia and no evidence of cardiovascular disease were randomly allocated to open-label ezetimibe monotherapy 10 mg/day (EZT group) or therapeutic lifestyle changes (TLC group).

Plasma triglyceride levels and body mass index values are the most important determinants of prebeta-1 HDL concentrations in patients with various types of primary dyslipidemia.

Objective: Experimental studies have shown that the prebeta-1 subclass of high-density lipoprotein particles (prebeta-1 HDL) may play an important role in the reverse cholesterol transport pathway as the initial acceptors of cellular cholesterol. The aim of the present study was the direct comparison of prebeta-1 HDL values in individuals with various types of primary dyslipidemias.

Methods: Four hundred and eighty-six unrelated individuals were included in the study.

Kidney function and estimated vascular risk in patients with primary dyslipidemia.

Background: Chronic kidney disease (CKD) is associated with increased vascular risk. Some studies suggested that considering markers of CKD might improve the predictive accuracy of the Framingham risk equation.

Aim: To evaluate the links between kidney function and risk stratification in patients with primary dyslipidemia.

Increased serum ferritin concentrations and liver enzyme activities in patients with metabolic syndrome.

Emerging scientific evidence suggests that increases in body iron represent a risk factor for the development of metabolic syndrome and diabetes. The aim of our study was to determine the body iron stores in patients with metabolic syndrome, and to evaluate the potential relationship of iron overload with specific features of the metabolic syndrome, such as fatty liver. A total of 490 individuals were enrolled.

Orlistat-associated adverse effects and drug interactions: a critical review.

Orlistat, an anti-obesity drug, is a potent and specific inhibitor of intestinal lipases. In light of the recent US FDA approval of the over-the-counter sale of orlistat (60 mg three times daily), clinicians need to be aware that its use may be associated with less well known, but sometimes clinically relevant, adverse effects. More specifically, the use of orlistat has been associated with several mild-to-moderate gastrointestinal adverse effects, such as oily stools, diarrhoea, abdominal pain and faecal spotting.

Hypertriglyceridaemic waist phenotype criteria and prevalent metabolic triad in women.

Background: To assess the metabolic profile and the prevalence of the metabolic triad (i.e. hyperinsulinaemia, hyperapobetalipoproteinaemia, and decreased low-density lipoprotein particle size) in women characterized by the hypertriglyceridaemic waist (HTGW) phenotype and to identify cut-off values for triglycerides and waist circumference, effectively discriminating women with the metabolic triad.

Fibrinogen, lipoprotein (a), albumin and bilirubin (F-L-A-B) levels and cardiovascular risk calculated using the Framingham equation.

Objectives: To determine the correlation between cardiovascular risk calculated using the Framingham equation and the circulating levels of 4 'emerging'predictors of vascular events: fibrinogen (Fib), lipoprotein (a) (Lp(a)), albumin (Alb) and bilirubin (Bil) (F-L-A-B).

Patients And Methods: A retrospective survey was carried out using patients referred to a specialist university-based clinic. A total of 376 patients with primary dyslipidaemia (209 men), without overt vascular disease, had their cardiovascular risk estimated using the Framingham equation.

Effect of ezetimibe in patients who cannot tolerate statins or cannot get to the low density lipoprotein cholesterol target despite taking a statin.

Background: Recent guidelines underline the need for high-risk patients to reach strict low density lipoprotein cholesterol (LDL-C) targets (1.8-2.6 mmol/L; 70-100 mg/dL), and specifically mention the possible use of combination therapy (e.

Differential effect of hypolipidemic drugs on lipoprotein-associated phospholipase A2.

Objective: Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a predictor for incident atherosclerotic disease. We investigated the effect of 3 hypolipidemic drugs that exert their action through different mechanisms on plasma and lipoprotein-associated Lp-PLA2 activity and mass.

Methods And Results: In 50 patients with Type IIA dyslipidemia were administered rosuvastatin (10 mg daily), whereas in 50 Type IIA dyslipidemic patients exhibiting intolerance to previous statin therapy were administered ezetimibe as monotherapy (10 mg daily).

Effect of ezetimibe monotherapy on the concentration of lipoprotein subfractions in patients with primary dyslipidaemia.

Background: Recent studies suggest that the distribution of lipoprotein subfractions is an independent predictor of vascular events. Therefore, we evaluated the effect of ezetimibe (a selective cholesterol transport inhibitor) on the concentrations of lipoprotein subfractions in patients with primary dyslipidaemia.

Materials And Methods: Patients (n = 50) with primary dyslipidaemias were recruited.

Gender-related and age-related urinalysis of healthy subjects by NMR-based metabonomics.

NMR-based metabonomic analysis is a well-established approach to characterizing healthy and diseased states. The aim of this study was to investigate inter-individual variability in the metabolic urinary profile of a healthy Greek population, not subjected to strict dietary limitations, by NMR-based metabonomics. The overall metabonomic urinalysis showed a homogeneous distribution among the population.

Plasma lipoproteins and triacylglycerol are predictors of small, dense LDL particles.

Recently published data suggest that the assessment of LDL subfraction profiles may contribute to the determination of the cardiovascular risk. In this study, we tested the ability of various metabolic parameters to estimate the presence or the preponderance of small, dense LDL particles (sdLDL). One hundred and fifty individuals attending the Outpatient Clinics of the University Hospital of Ioannina for suspected metabolic abnormalities were included in the study.

The relationship between circulating fibrinogen and lipoprotein (a) levels in patients with primary dyslipidemia.

The correlation between 2 predictors of vascular events, plasma fibrinogen and serum lipoprotein (a), was evaluated in patients referred to a specialist clinic because of primary hyperlipidemia. A significant correlation existed between fibrinogen and lipoprotein (a) in nonsmokers but not in smokers. Plasma fibrinogen concentration correlated positively and significantly with serum lipoprotein (a) levels in men nonsmokers without cardiovascular disease and in women nonsmokers with cardiovascular disease.

Clinical importance and therapeutic modulation of small dense low-density lipoprotein particles.

The National Cholesterol Education Programme Adult Treatment Panel III accepted the predominance of small dense low-density lipoprotein (sdLDL) as an emerging cardiovascular disease (CVD) risk factor. Most studies suggest that measuring low-density lipoprotein (LDL) particle size, sdLDL cholesterol content and LDL particle number provides additional assessment of CVD risk. Therapeutic modulation of small LDL size, number and distribution may decrease CVD risk; however, no definitive causal relationship is established, probably due to the close association between sdLDL and triglycerides and other risk factors (e.

Non-low-density lipoprotein cholesterol-associated actions of ezetimibe: an overview.

Ezetimibe, an intestinal cholesterol absorption inhibitor, lowers circulating low-density lipoprotein cholesterol (LDL-C) levels both when administered as monotherapy and in combination with other hypolipidaemic drugs, mostly statins. This review focuses on the effects of ezetimibe on non-LDL-C-associated variables. In most studies, ezetimibe effectively reduced triglyceride and increased high density lipoprotein cholesterol levels.

The hypertriglyceridemic waist phenotype is a predictor of elevated levels of small, dense LDL cholesterol.

The hypertriglyceridemic waist (HTGW) phenotype (hypertriglyceridemia and increased waist circumference) has been proposed as an inexpensive tool to monitor individuals with the atherogenic metabolic triad, hyperinsulinemia, hyperapobetalipoproteinemia, and increased levels of small, dense LDL (sdLDL) particles. We assessed the association of the HTGW phenotype with the metabolic syndrome (MetSyn) and the atherogenic metabolic triad in inhabitants (n = 260) of northwestern Greece attending the Outpatient Lipid Clinic of the University Hospital of Ioannina. The LDL subfractions were assessed using the Lipoprint LDL System.

Rosuvastatin increases alpha-1 microglobulin urinary excretion in patients with primary dyslipidemia.

The renoprotective effect of statins has been recently disputed because of observations of proteinuria associated with rosuvastatin treatment, the newest drug of the class. Statin-induced proteinuria findings were mainly based on crudely quantitative dipstick assays. The authors quantitatively evaluated the effect of rosuvastatin at the recommended starting dose of 10 mg/d, on urine protein excretion in patients with primary dyslipidemia.
