Emotional eating as a mediator between anxiety and cholesterol in population with overweight and hypertension
2016
Although the relationship between cholesterol and mood states (especially anxiety) has been well studied, few researches have included the role of eating styles in this relationship. This study explored the associations among eating styles, negative emotional symptoms, and levels of cholesterol (and other medical variables) in a population with hypertension and overweight or obesity, analyzing the possible mediation mechanisms involved. A cross-sectional study was conducted in 68 adults with hypertension and overweight/obesity, and stepwise multiple regression analysis and mediation analyses were carried out to test the hypothesis that eating styles mediate the relationship between negative…
Lomitapide affects HDL composition and function
2016
Abstract Background Lomitapide reduces low-density lipoprotein-cholesterol (LDL-C) but also high-density lipoprotein-cholesterol (HDL-C) levels. The latter may reduce the clinical efficacy of lomitapide. We investigated the effect of lomitapide on HDL-C levels and on cholesterol efflux capacity (CEC) of HDL in patients with homozygous familial hypercholesterolemia (HoFH). Methods and results Four HoFH patients were treated with increasing dosages of lomitapide. Lomitapide decreased LDL-C (range −34 to −89%). Total HDL-C levels decreased (range −16 to −34%) with a shift to buoyant HDL. ABCA1-mediated CEC decreased in all patients (range −39 to −99%). The changes of total, ABCG1- and SR-BI-me…
Effects of phytosterol ester-enriched low-fat milk on serum lipoprotein profile in mildly hypercholesterolaemic patients are not related to dietary c…
2010
Phytosterols (PS) are recommended to reduce LDL-cholesterol. However, the influence of cholesterol and fat intake on the lipid-lowering effect of PS in mildly hypercholesterolaemia is unclear. Thus, the aim of the present study was to evaluate whether the efficacy of PS is related to the composition of saturated fat and dietary cholesterol intake. Additionally, serum carotenoid content was analysed to evaluate to what extent it was undermined by PS. This was a 3-month randomised, parallel trial with a three-arm design. Patients were divided into three groups: healthy diet (n 24), healthy diet + PS (n 31) and free diet + PS (n 29), receiving 2 g/d of PS. Healthy and free diets were character…
Homozygous familial hypercholesterolemia with severe involvement of the aortic valve—A sibling‐controlled case study on the efficacy of lipoprotein a…
2020
Background Homozygous familial hypercholesterolemia (hoFH) can cause severe atherosclerotic cardiovascular disease (ASCVD) in early infancy. Diagnosis and initiation of effective lipid-lowering therapy (LLT) are recommended as early as possible to prevent ASCVD-related morbidity and mortality. Methods The clinical courses of a pair of siblings with an identical hoFH genotype, who exhibited major similarities of their clinical phenotype were analyzed in a case-control fashion including the family. Results The older sibling was diagnosed with hoFH at the age of 4. Untreated LDL-cholesterol (LDL-C) was 17 mmol/L (660 mg/dL). LLT including lipoprotein apheresis (LA) was initiated and has been s…
Reduced penetrance of autosomal dominant hypercholesterolemia in a high percentage of families: importance of genetic testing in the entire family.
2011
Abstract Background Autosomal dominant hypercholesterolemias (ADHs) are characterised by increased plasma levels of total and LDL cholesterol, predisposing to premature atherosclerosis. ADHs comprise several diseases with undistinguishable phenotype, caused by mutations in different genes: LDLR, APOB and PCSK9. Genetic studies are usually performed in patients with altered cholesterol levels. However, some persons carrying pathogenic mutations are normocholesterolemic and there are no further studies about this subject. We have studied the frequency of families and individuals carrying ADH mutations who do not present the disease in Spanish population. Methods We have analysed genes known t…
Inhibition of thromboxane biosynthesis and platelet function by simvastatin in type IIa hypercholesterolemia
1995
Abstract Thromboxane A 2 (TXA 2 ) biosynthesis is enhanced in the majority of patients with type IIa hypercholesterolemia. Because simvastatin (a 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitor) was previously shown to reduce platelet aggregation and TXB 2 production ex vivo, we investigated TXA 2 biosynthesis and platelet function in 24 patients with type IIa hypercholesterolemia randomized to receive in a double-blind fashion simvastatin (20 mg/d) or placebo for 3 months. The urinary excretion of 11-dehydro-TXB 2 , largely a reflection of platelet TXA 2 production in vivo, was measured by a previously validated radioimmunoassay technique. Blood lipid levels and urinary 11-dehyd…
Structure, chromosomal localization, and brain expression of human Cx36 gene
1999
Rat connexin-36 (Cx36) is the first gap junction protein shown to be expressed predominantly in neuronal cells of the mammalian central nervous system. As a prerequisite for studies devoted to the investigation of the possible role of this connexin in human neurological diseases, we report the cloning and sequencing of the human Cx36 gene, its chromosomal localization, and its pattern of expression in the human brain analyzed by radioactive in situ hybridization. The determination of the human gene sequence revealed that the coding sequence of Cx36 is highly conserved (98% identity at the protein level with the mouse and rat Cx36 and 80% with the ortholog perch and skate Cx35), and that the…
Health literacy in familial hypercholesterolemia: A cross-national study.
2018
Background High rates of inadequate health literacy are associated with maladaptive health outcomes in chronic disease including increased mortality and morbidity rates, poor treatment adherence and poor health. Adequate health literacy may be an important factor in the effective treatment and management of familial hypercholesterolemia, and may also be implicated in genetic screening for familial hypercholesterolemia among index cases. The present study examined the prevalence and predictors of health literacy in familial hypercholesterolemia patients attending clinics in seven countries. Design Cross-sectional survey. Methods Consecutive FH patients attending clinics in Australia, Brazil,…
Real-time spatial compound sonography of Achilles tendon in patients with heterozygous familial hypercholesterolaemia and normal physical examination
2007
This study was undertaken to assess the prevalence and ultrasound features of Achilles tendon xanthomas (ATX) in patients with heterozygous familial hypercholesterolemia (HFH) and normal physical examination studied with high-resolution ultrasonography (HRUS) and, secondarily, to evaluate the role of real-time spatial compound sonography (CS) in terms of image quality.Both Achilles tendons of 40 patients with HFH were studied with HRUS and CS. Two experienced radiologists evaluated by consensus the presence of ATX described as (1) tendon thickening and/or (2) focal hypoechoic areas and the quality of images obtained with the two techniques.Ten out of 80 tendons showed thickening (mean: 11.2…
Influence of genetic variation at the apo A-I gene locus on lipid levels and response to diet in familial hypercholesterolemia
1998
We have examined the apo AI - 75 (G/A) and apo AI + 83(MspI +/-) polymorphisms at the APOA1 gene locus for associations with plasma lipid levels and response to an NCEP-I diet in 69 (44 women, 25 men) heterozygotes for familial hypercholesterolemia (FH). Subjects were studied at baseline (after consuming for one month a diet with 35%, fat, 10% saturated, and 300 mg/day cholesterol) and after 3 months of an NCEP-I diet. No gender-related differences for any of the lipid variables examined were found and the data were analyzed for men and women combined. For the apo AI - 75 (G/A) polymorphism, there were 51 G/G and 18 G/A subjects. At baseline, G/A subjects showed significantly lower total ch…
