Effects of Chitosan on Plasma Lipids and Lipoproteins
2014
Chitosan can favorably modulate plasma lipids, but the available data are not conclusive. We evaluated the effect of chitosan on plasma lipids and lipoproteins in 28 patients with plasma triglyceride levels >150 mg/dL (mean age: 63 ± 12 years), not taking other lipid-lowering agents. All patients received a chitosan derived from fungal mycelium (Xantonet, Bromatech, Italy) at a fixed dose of 125 mg/d in addition to their current medications for 4 months. Polyacrylamide gel electrophoresis was used to measure low-density lipoprotein (LDL) subclasses. After treatment, total cholesterol reduced by 8%, LDL cholesterol by 2%, and triglycerides by 19%, with a concomitant 14% increase in high-…
Plasma levels of lipoproteins and apolipoproteins in congenital hypothyroidism: Effects of l-thyroxine substitution therapy
1995
Thyroid status in humans is an important factor in the regulation of lipoprotein metabolism. There are several data on hypothyroidism in the adult population, but less information is available about congenital hypothyroidism. Since lipid metabolism at birth is substantially different from that of adults, it is not likely that the same abnormalities that occur in adult hypothyroidism are also present when this is diagnosed at early life. We studied 16 subjects with congenital hypothyroidism, seven at the time of diagnosis and also after normalization of thyroid hormone levels over a period of 2.0 +/- 1.0 months of substitution therapy with L-thyroxine (5.9 +/- 1.2 micrograms/kg/d) and nine a…

Lipid profile, cardiovascular disease and mortality in a Mediterranean high-risk population: The ESCARVAL-RISK study
2017
Introduction The potential impact of targeting different components of an adverse lipid profile in populations with multiple cardiovascular risk factors is not completely clear. This study aims to assess the association between different components of the standard lipid profile with allcause mortality and hospitalization due to cardiovascular events in a high-risk population. Methods This prospective registry included high risk adults over 30 years old free of cardiovascular disease (2008-2012). Diagnosis of hypertension, dyslipidemia or diabetes mellitus was inclusion criterion. Lipid biomarkers were evaluated. Primary endpoints were all-cause mortality and hospital admission due to corona…
Management of homozygous familial hypercholesterolaemia in two brothers
2018
Homozygous familial hypercholesterolaemia (HoFH) is a rare, genetic disorder of abnormally high levels of low-density lipoprotein cholesterol (LDL-C) requiring aggressive interventions to retard the evolution of atherosclerotic cardiovascular disease. We treated two brothers (ages 46 years and 47 years) with HoFH with statins, lipoproteinapheresis (LA) and the microsomal triglyceride transfer protein inhibitor lomitapide. Both brothers carried the p.Thr434Arg homozygous LDLR mutation and had childhood total cholesterol levels >700 mg/dL. Inter-LA LDL-C levels remained high; therefore, they were given escalating doses of oral lomitapide (5–10 mg/day). One brother was able to maintain LDL-C l…
Insulin resistance syndrome and autonomically mediated physiological responses to experimentally induced mental stress in adolescent boys
1996
We investigated the relationship between hemodynamic and other autonomically mediated responses to experimentally induced mental stress and the parameters of the insulin resistance syndrome (IRS) in 48 healthy adolescent boys. Mental stress was induced with mental arithmetic and the Stroop Color-Word Test. Heart rate (HR), finger blood volume (FBV), and skin conductance level (SCL) were recorded continuously during task performance. IRS parameters measured were serum insulin, high-density lipoprotein (HDL) cholesterol, serum triglyceride (TG), systolic blood pressure (SBP), subscapular skinfold (SSF), and subscapular to triceps skinfold ratio (STR). The results indicated that a high level a…
Nitric oxide production is increased in severely obese children and related to markers of oxidative stress and inflammation
2011
Nitric oxide (NO) is the major endothelium-derived relaxing factor. The aim of the present study was to evaluate NO synthesis and metabolism in severely obese children with different degrees of metabolic risk and to ascertain their relation with the parameters of oxidative stress and inflammation.The study involved 60 obese children evaluated with respect to metabolic risk factors (MRFs) (324 MRFs and 28 ≥ 4 MRFs) and 50 normal weight children between 7 and 14 years of age. Nutritional status was assessed by clinical and anthropometric examination. MRFs (serum lipid profile, insulin resistance indexes, blood pressure) in addition to uric acid, homocysteine, leptin, and inflammatory markers …
Polyunsaturated fatty acids interact with the PPARA-L162V polymorphism to affect plasma triglyceride and apolipoprotein C-III concentrations in the F…
2005
Peroxisome proliferator-activated receptor alpha (PPARalpha) is a nuclear transcription factor regulating multiple genes involved in lipid metabolism. It was shown that a common leucine to valine (L162V) substitution at the PPARalpha gene (PPARA) is functional and affects transactivation activity of PPARalpha ligands, such as PUFA, on a concentration-dependent basis. The current study examined this gene-nutrient interaction in relation to plasma lipid variables in a population-based study consisting of 1003 men and 1103 women participating in the Framingham cohort and consuming their habitual diets. We found significant gene-nutrient interactions between the L162V polymorphism and total PUF…
Lp(a) levels in patients undergoing aorto-coronary bypass surgery.
1992
The aims of this study were to evaluate plasma lipid, apoprotein and Lp(a) levels in patients with severe coronary atherosclerosis undergoing aorto-coronary bypass surgery (BP) and to relate these parameters to the involvement of one or more vessels. Seventy-seven male patients and 77 cardiovascular disease-free controls, matched for sex, age and body weight were studied. Higher triglyceride and apo B levels with lower HDL-cholesterol and apo A-I levels were found in BP patients in comparison with the controls. Lp(a) levels were slightly, but not significantly, increased. Moreover BP patients presented a significantly higher prevalence of HDL-cholesterol levels below 35 mg dl-1 (49.3% vs 22…
Apolipoprotein profile in type II diabetic patients with and without coronary heart disease.
1990
Diabetes mellitus is frequently associated with lipid metabolism abnormalities. In the present study the lipid and apolipoprotein profiles have been compared in type II diabetic subjects with (n = 30) and without (n = 30) coronary heart disease (CHD). All subjects were studied after good metabolic control had been achieved. Significant differences in plasma lipids and apolipoproteins were seen in diabetic patients with CHD in comparison with diabetics without CHD. Patients with CHD presented higher total cholesterol, triglyceride, LDL-cholesterol, apo B, apo CII and apo CIII levels and total cholesterol/HDL-cholesterol and LDL-cholesterol HDL-cholesterol ratios and lower HDL-cholesterol val…
