ABSTRACT

Cardiovascular disease is linked to high serum low density lipoprotein (LDL)-cholesterol levels. Cardiovascular risk may be indirectly influenced by genetic load. Serum LDL-cholesterol levels may be reduced by the consumption of food enriched with plant sterols (PS). The aim was to test a plant sterol treatment on cholesterol levels according to different genetic polymorphisms. A pilot interventional trial was performed in 26 children (n = 16 girls, n = 10 boys). Seven hundred milliliters/day of commercial skimmed milk with added plant sterols delivering 2.2 g plant sterols were ingested for three weeks. Blood draws were performed at the baseline and end of the study. Significant modifications of non-high density lipoprotein (HDL)-cholesterol (p = 0.010; p = 0.013) and LDL-cholesterol (p = 0.004; p = 0.013) levels appeared in the genes LIPC C-514T and PPAR-α L162V carriers. No statistically significant differences were observed for other genes. LIPC C-514T and PPAR-alpha L162V carriers could benefit from a plant sterol supplement to ameliorate hypercholesterolemia.

ABSTRACT

Raised serum cholesterol concentration is a well-established risk factor in cardiovascular disease. In addition, genetic load may have an indirect influence on cardiovascular risk. Plant-based sterol-supplemented foods are recommended to help reduce the serum low-density lipoprotein cholesterol level. The objective was to analyse the influence of different polymorphisms in hypercholesterolemia patients following a dietary treatment with plant sterols. A randomised double-blind cross-over controlled clinical trial was carried out in 45 people (25 women). Commercial milk, containing 2.24 g of sterols, was ingested daily during a 3-week period, and then the same amount of skim milk, without sterols, was consumed daily during the 3-week placebo phase. Both phases were separated by a washout period of 2 weeks. At the beginning and end of each phase, blood draws were performed. Genes LIPC C-514T and APOA5 C56G are Ser19Trp carriers and greatly benefit from sterol intake in the diet. LIPC C-514T TT homozygous carriers had lower low-density lipoprotein cholesterol (LDL-c) levels than CC homozygote and CT heterozygote carriers after the ingestion of plant sterols (p = 0.001). These two genes also showed statistically significant changes in total cholesterol levels (p = 0.025; p = 0.005), and no significant changes in high-density lipoprotein (HDL) cholesterol levels (p = 0.032; p = 0.003), respectively. No statistically significant differences were observed for other genes. Further studies are needed to establish which genotype combinations would be the most protective against hypercholesterolemia.

ABSTRACT

Introducción: la hipercolesterolemia es uno de los principales factores de riesgo en la enfermedad cardiovascular. Los esteroles vegetales se han postulado como agentes reguladores y beneficiosos para el control de esta.Objetivo: analizar el efecto de los esteroles vegetales añadidos en una leche en la reducción del colesterol plasmático en adultos jóvenes.Métodos: ensayo clínico, controlado, aleatorizado, doble ciego y cruzado. Los esteroles (2,24 g diarios) fueron administrados en dos tomas de 350 ml de una leche comercial desnatada, durante dos periodos de 3 semanas, separados por una "fase de lavado" de 2 semanas, en el grupo experimental. Al grupo control se le administró la misma cantidad de leche desnatada, sin esteroles. Tanto al inicio como al final de cadaperiodo de intervención se extrajeron muestras sanguíneas. Se analizaron la composición corporal, hábitos de salud y los siguientes marcadores sanguíneos: perfil lipídico, hematológico, inflamación, etc.Resultados: se incluyeron 54 personas en el estudio con una edad media de 38,8 ± 7,3 años. La diferencia porcentual entre los marcadores basales y finales para el colesterol total, colesterol-LDL, colesterol-HDL, triglicéridos y colesterol no-HDL fueron del 9,73%, 12,5%, 1,9%, 3,15% y 13,2%, respectivamente. Se obtuvieron diferencias estadísticamente significativas entre el grupo experimental y el grupo control, para todos los marcadores analizados excepto para los triglicéridos.Conclusión: los esteroles vegetales suministrados en un alimento de consumo habitual, como la leche, pueden ser una estrategia terapéutica no farmacológica para el control de la hipercolesterolemia de alto interés sanitario.

Introduction: Hypercholesterolemia is one of the most relevant risk factors in cardiovascular disease, and plant sterols have been postulated as beneficial regulator agents for the control of the disease. Objective: Analyze the effect of added plant sterols in milk in reducing plasma cholesterol in young adults. Methods: A randomized, clinical controlled trial, double-blind crossover study. Sterols (2.24 g per day) were administrated in two doses of 350 ml of commercial skimmed milk, during two phases of three weeks respectively separated by a washout period of 2 weeks, in the experimental group. The same amount of skimmed milk was administrated to the control group, but with no sterols. At the beginning and end of each phase blood draws were performed. Anthropometric data and health habits were analyzed and the following blood laboratory markers: lipid profile, hematology, inflammation, etc. were collected. Results: Fifty four people were included in the study with an average age of 38.8 ± 7.3 years. Differences between baseline and final scores percentage were 9.73 %, 12.5 %, 1.9 %, 3.15 % y 13.2 % for total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides and No HDL-cholesterol, respectively. Statistically significant differences were found between the experimental group and the control group for all biomarkers analyzed except for triglycerides. Conclusion: Plant sterols supplied in commonly consumed food, such as milk, may be a non- pharmacological therapeutic strategy of hypercholesterolemia with high health interest (AU)

ABSTRACT

Introducción: en estos últimos años, paralelamente a la epidemia de obesidad, se ha producido un aumento de las dislipemias en la población pediátrica. En estas dislipemias es posible que los triglicéridos sanguíneos también tengan un papel importante. Los esteroles vegetales se han mostrado eficaces en el tratamiento de la hipercolesterolemia, pero no de la hipertrigliceridemia. Nuestro objetivo en este estudio es determinar la eficacia de la leche enriquecida en fitoesteroles para la disminución de la hipertrigliceridemia en la población infantil. Población y método: se diseñó un ensayo clínico, controlado, aleatorizado, y doble ciego, con leche desnatada enriquecida con esteroles vegetales y leche desnatada no enriquecida. Se incluyeron 67 pacientes pediátricos. Resultados: tras la ingesta observamos diferencias en la trigliceridemia final entre la leche desnatada enriquecida con esteroles vegetales y la leche desnatada no enriquecida con esteroles. El efecto atribuible a la ingesta de la leche enriquecida con fitosteroles vegetales fue de una disminución de 5,88 mg/dl. Conclusión: concluimos que la leche enriquecida con esteroles vegetales (2,24 gr de esteroles vegetales al día) podría constituir una estrategia adecuada para el tratamiento de la hipertrigliceridemia en pacientes pediátricos (AU)


Introduction: in the last few years, as the rate of childhood obesity has been rising, there has been a parallel increase in the incidence of dislipemia in the pediatric population, in which blood triglycerids might play an important role. Plant sterols have been shown to be useful in the treatment of hypercholesterolemia, but not of hypertrygliceridemia. Our study focusses on determining the efficacy of phytosterol-supplemented milk for the treatment of hypertriglyceridemia in children. Study Population and Method: we designed a double-blind, randomized, controlled clinical trial on 67 pediatric patients. The treatment group received low-fat, phytosterol-supplemented milk and the control group received low-fat conventional milk. Results: we observed differences in triglyceridemia between the phytosterol-supplemented group and the non-supplemented group. The effect attributable to the intake of milk supplemented with plant sterols was a reduction of triglyceridemia of 5.88 mg/dl compared with the control group. Conclusion: we conclude that phytosterol-supplemented milk (2.24 gr of plant sterols daily) might be an adequate tool in the management of hypertriglyceridemia in pediatric patients (AU)
