ABSTRACT

A dislipidemia é um distúrbio metabólico frequente na síndrome dos ovários policísticos (SOP) e, possivelmente, contribui para um aumento do risco de doenças cardiovasculares. A avaliação do risco cardiovascular de cada paciente define as metas lipídicas a serem atingidas por meio da terapêutica recomendada para a correção da dislipidemia. Alimentação saudável, perda de peso e implementação de um programa regular de atividade física contribuem para a melhora do perfil lipídico. A terapia farmacológica deve ser reservada para as pacientes que não atingiram as metas lipídicas após modificações na dieta e regularização da atividade física ou nas pacientes com alto risco cardiometabólico.(AU)

ABSTRACT

Las variantes de ANGPTL3 con pérdida de función están asociadas con efectos beneficiosos sobre el metabolismo lipídico y de carbohidratos y con riesgo reducido de enfermedad coronaria. Los cambios beneficiosos en los parámetros lipídicos que se obtienen con la inhibición de ANGPTL3 junto con la reducción en aterosclerosis que se observa en modelos animales y en estudios epidemiológicos de genética humana hacen de ANGPTL3 un nuevo objetivo terapéutico para prevenir las enfermedades cardiovasculares. Dos estrategias novedosas han surgido para inhibir esta proteína: un anticuerpo monoclonal y un oligonucleótido antisentido, con capacidad para reducir tanto el colesterol como los triglicéridos plasmáticos en forma notoria. Aunque el horizonte es promisorio, todavía no sabemos si los efectos de una variante presente desde el comienzo de la vida serán reproducidos por la inhibición de esta proteína que se realiza más tarde en la vida a través de una intervención farmacológica. (AU)


Loss-of-function ANGPTL3 variants are associated with beneficial effects on carbohydrate and lipid metabolism, and reduced risk of coronary heart disease. The beneficial changes in lipid parameters obtained by ANGPTL3 inhibition together with atheroprotection observed in animal models and in epi-demiological studies of human genetics make ANGPTL3 a new therapeutic target to prevent cardiovascular diseases. Two novel strategies have emerged to inhibit this protein: a monoclonal antibody and an antisense oligonucleotide, with the ability to significantly lower plasma cholesterol and triglycerides. Although the horizon is promising, we still do not know if the effects of a variant present from the beginning of life will be reproduced by the inhibition of this protein that takes place later in life through a pharmacological intervention.

ABSTRACT

Resumo Fundamento: O uso de estatinas destaca-se como a terapia mais frequentemente utilizada para o tratamento de dislipidemias e pode ser considerado a intervenção farmacológica mais eficiente para a redução da lipoproteína de baixa densidade (LDL). Por outro lado, o treinamento físico pode ser considerado uma estratégia não farmacológica eficiente e segura para promover melhorias no perfil lipídico. No entanto, não se sabe qual seria a influência das estatinas nas adaptações lipídicas decorrentes do treinamento aquático em populações com dislipidemia. Objetivos: Analisar a influência do uso de sinvastatina nas adaptações lipídicas decorrentes do treinamento aeróbico em meio aquático e de resistência em mulheres idosas com dislipidemia. Métodos: Sessenta e nove mulheres idosas (66,13 ± 5,13 anos), sedentárias e dislipidêmicas, tanto não usuárias quanto usuárias de sinvastatina (20 mg e 40 mg), foram randomizadas nos 3 grupos seguintes: treinamento aeróbico em meio aquático (WA), treinamento de força em meio aquático (WR) e grupo controle (GC). A duração total das intervenções, para todos os grupos experimentais, foi de 10 semanas, com 2 sessões semanais. As análises bioquímicas foram realizadas antes do início das intervenções e repetidas após o final do ensaio. Foram utilizadas equações de estimativa generalizada para comparar esses dados, estabelecendo α = 0,05. Resultados: Na análise por intenção de tratar, as participantes medicadas demonstraram uma redução de magnitude maior do colesterol total (CT) (−3,41 a −25,89 mg.dl−1; p = 0,038), LDL (−5,58 a −25,18 mg.dl−1; p = 0,007) e da relação CT/HDL (−0,37 a −0,61; p = 0,022) quando comparadas às participantes não medicadas, essa redução sendo estatisticamente significativa apenas no grupo WR. Conclusões: O uso de estatina incrementa as adaptações promovidas pelo treinamento físico aquático no CT, nos níveis de LDL e na relação CT/HDL, sendo mais pronunciado após WR.


Abstract Background: Statin use is highlighted as the most commonly utilized therapy for the treatment of dyslipidemias and can be considered as the most efficient pharmacological intervention for low-density lipoprotein (LDL) reduction. On the other hand, physical training can be considered an efficient and safe non-pharmacological strategy to promote improvements in lipid profile. However, the influence of statins on lipid adaptations arising from water-based training in populations with dyslipidemia is not known. Objectives: To analyze the influence of simvastatin use on lipid adaptations arising from water-based aerobics and resistance training in elderly women with dyslipidemia. Methods: Sixty-nine elderly (66.13 ± 5.13 years), sedentary, and dyslipidemic women, both non-users and users of simvastatin (20 mg and 40 mg), were randomized into the following 3 groups: water-based aerobic training (WA), water-based resistance training (WR), and control group (CG). Total duration of interventions, for all experimental groups consisted of 10 weeks, with 2 weekly sessions. Biochemical analyses were performed before the beginning of the interventions and repeated after the end of the trial. Generalized estimating equations were used to compare these data, setting α = 0.05. Results: In intention-to-treat analysis, the medicated participants obtained a greater magnitude of decrease in total cholesterol (TC) (−3.41 to −25.89 mg.dl−1; p = 0.038), LDL (−5.58 to −25.18 mg.dl−1; p = 0.007) and TC/HDL ratio (−0.37 to −0.61; p = 0.022) when compared to the non-medicated participants, and this decrease was statistically significant only in the WR group. Conclusions: Statin use enhances the adaptations promoted by water-based physical training in CT, LDL levels, and CT/HDL ratio, and it is more pronounced after WR.

ABSTRACT

The potential inhibitory effect of the insulin mimicking agent, vanadium on type 2 diabetes mellitus (T2DM)induced alterations to the aorta ultrastructure associated with the suppression of dyslipedima and biomarkers of inflammation has not been investigated before. Therefore, we tested whether vanadium can protect against aortic injury induced secondary to T2DM possibly via the inhibition of blood lipid and inflammatory biomarkers. T2DM was induced in rats by a high-fat diet and streptozotocin (50 mg/ kg), and the treatment group started vanadium treatment five days post diabetic induction and continued until being sacrificed at week 10. Using light and electron microscopy examinations, we observed in the model group substantial damage to the aorta tissue such as damaged endothelium, degenerative cellular changes with vacuolated cytoplasm and thickened internal elastic lamina that were substantially ameliorated by vanadium. Administration of vanadium to diabetic rats also significantly (p<0.05) reduced blood levels of glucose, hyperlipidemia and biomarkers of inflammation (TNF-a, IL-6). We conclude that vanadium protects against T2DM-induced aortic ultrastructural damage in rats, which is associated with the inhibition of blood sugar and lipid and inflammatory biomarkers.


El potencial efecto inhibidor del agente imitador de la insulina, el vanadio en las alteraciones inducidas por la diabetes mellitus tipo 2 (DM2) en la ultraestructura de la aorta, asociada con la supresión de dislipidemia y los biomarcadores de inflamación no se ha investigado anteriormente. El objetivo fue estudiar las propiedades del vanadio para proteger contra la lesión aórtica inducida a la DM2, a través de la inhibición de los lípidos sanguíneos y los biomarcadores inflamatorios. La DM2 fue inducida en ratas con una dieta alta en grasas y estreptozotocina (50 mg / kg), y el grupo de tratamiento fue sometido a un régimen continuo con vanadio, cinco días después de la inducción diabética hasta ser sacrificadas en la semana 10. Se utilizaron exámenes de luz y microscopía electrónica en el grupo modelo y se observó un daño sustancial al tejido de la aorta, como también en el endotelio; los cambios celulares degenerativos con citoplasma vacuolado y lámina elástica interna engrosada mejoró sustancialmente con vanadio. La administración de vanadio a ratas diabéticas también redujo significativamente (p <0,05) los niveles sanguíneos de la glucosa, hiperlipidemia y los biomarcadores de inflamación (TNFa, IL-6). En conclusión, el vanadio protege contra el daño ultraestructural aórtico inducido por T2DM en ratas, que es asociado con la inhibición del azúcar en la sangre y los biomarcadores de lípidos y de inflamatorios.

ABSTRACT

The control of dyslipidemia using plants is an important subject of studies since it has numerous benefits in cardiovascular protection. The objective of this study was to evaluate the effect of three Camellia sinensis L. teas (green, red, and white) on left ventricular hypertrophy and insulin resistance in low-density lipoprotein receptor knockout (LDLr-/-) mice fed a high-fat diet. The LDLr-/- mice were divided into four experimental groups: Group C: standard feed; Group CT: standard feed and three teas, Group HL: high-fat feed; HLT Group: high-fat feed and three teas. The three types of tea (green, red, and white) originated from different processing of the Camellia sinensis L. plant, and were administered associated once a day at a dose of 25 mg/kg by gavage for 60 days. The teas partially prevented hyperlipidemia, the decrease of the serum levels of high-density lipoproteins (HDL), insulin resistance, and increased C-reactive protein (CRP) levels, and completely prevented left ventricular hypertrophy in LDLr -/- mice of the HLT group. In conclusion, the three Camellia sinensis L. teas used to control genetic dyslipidemia associated with a high-fat diet can be used as an auxiliary treatment associated with the control of lipid intake, thus promoting cardiac protection against hyperlipidemia.

ABSTRACT

OBJECTIVES: The number of bariatric procedures has significantly increased in Brazil, especially in the public Unified Health System. The present study describes health outcomes and medication use in obese patients treated in a major hospital that performs publicly funded surgery in Brazil. METHODS: A retrospective, single center study was conducted to collect real-world evidence of health outcomes and medication use in 247 obese patients (female, 82.2%) who underwent open Roux-en-Y gastric bypass. Changes in weight and body mass index (BMI), presence of apnea, hypertension, and type 2 diabetes (T2D), and medication use (hypertension, diabetes, and dyslipidemia) were assessed preoperatively and up to 24 months postoperatively. The mean cost of medications was calculated for the 12-month preoperative and 24-month postoperative periods. RESULTS: During the surgery, the mean age of patients was 43.42 years (standard deviation [SD], 10.9 years), and mean BMI was 46.7 kg/m2 (SD, 6.7 kg/m2). At 24 months, significant declines were noted in weight (mean, -37.6 kg), BMI (mean, -14.3 kg/m2); presence of T2D, hypertension, and apnea (-29.6%, -50.6%, and -20.9%, respectively); and number of patients using medications (-66.67% for diabetes, -41.86% for hypertension, and -55.26% for dyslipidemia). The mean cost of medications (total costs for all medications) decreased by >50% in 12-24 postoperative months compared to that in 12 preoperative months. CONCLUSION: Roux-en-Y gastric bypass successfully reduced weight, BMI, and comorbidities and medication use and cost at 24 months in Brazilian patients treated in the public Unified Health System.

ABSTRACT

La enfermedad cardiovascular secundaria a aterosclerosis es la principal causa de morbimortalidad en la población adulta a nivel mundial. Aunque las manifestaciones clínicas de aterosclerosis (enfermedad coronaria, accidente cerebrovascular y arteriopatía periférica) son excepcionales en la población pediátrica, la presencia de factores de riesgo para enfermedad cardiovascular, así como la adquisición de hábitos que favorecen su desarrollo, se observan ya desde edades tempranas. En el presente documento, se elaboraron recomendaciones, con dos objetivos principales: prevenir la aparición de factores de riesgo para enfermedad cardiovascular (prevención primordial) y detectar y tratar los que favorecen el desarrollo de aterosclerosis clínica (prevención primaria). Si bien las recomendaciones están dirigidas a la población pediátrica, el objetivo del trabajo conjunto de la Sociedad Argentina de Pediatría y la Sociedad Argentina de Cardiología es asegurar un abordaje integral y consensuado de la prevencion cardiovascular a lo largo de toda la vida, incluso, desde antes de la concepción.


Cardiovascular disease secondary to atherosclerosis is the leading cause of morbimortality in the adult population worldwide. Although clinical manifestations of atherosclerosis (coronary heart disease, stroke and peripheral vascular disease) are extremely rare in the pediatric population, the presence of risk factors for cardiovascular disease and the development of health-behavior patterns that promote them are observed since early childhood.In this document, recommendations were developed addressing two main goals: prevention of the risk factors development for cardiovascular disease (primordial prevention) and early detection and treatment of the risk factors to prevent clinical atherosclerosis (primary prevention). Even though the recommendations are addressed to the pediatric population, the aim of the collaborative work between the Sociedad Argentina de Pediatría and the Sociedad Argentina de Cardiología is to ensure a comprehensive and consensual approach of lifetime cardiovascular prevention beginning even before conception.

ABSTRACT

SUMMARY OBJECTIVE Diabetes is one of the leading causes of cardiovascular mortality. Over the last years, mortality has decreased significantly, more in individuals with diabetes than in healthy ones. That is mostly due to the control of other cardiovascular risk factors. The objective of our study was to analyze the dyslipidemia control in two diabetes cohorts. METHODS Patients from two distinct cohorts were studied, 173 patients from the BHS (Brasília Heart Study) and 222 patients from the BDS (Brazilian Diabetes Study). The data on dyslipidemia control were studied in both different populations. All patients had diabetes. RESULTS There are significant differences concerning comorbidities between the LDL-C and BDS groups. The average glycated hemoglobin is of 8.2 in the LDL-C > 100 group in comparison with 7.7 and 7.5 in the 70-100 and < 70 groups, respectively (p = 0.024). There is a higher percentage of hypertensive patients with LDL between 70-100 (63.9%), when comparing the < 70 and > 100 groups (54.3% and 54.9%, respectively; p = 0.005). Diastolic pressure is higher in the group with LDL > 100, with an average of 87 mmHg, in comparison with 82.6 mmHg and 81.9 mmHg in the 70-100 and < 70 groups, respectively (p = 0.019). The group with LDL > 100 has the greatest percentage of smokers (8.7%) in comparison with the groups with LDL between 70-100 and < 70 (5.6% and 4.3%, respectively; p = 0.015). There is also a difference in the previous incidence of coronaropathy. In the group with LDL < 70, 28.3% of patients had already experienced a previous infarction, compared with 11.1% and 10.6% in the 70-100 and > 100 groups, respectively (p < 0.001). CONCLUSIONS The data in our study have shown that the dyslipidemia control in diabetic patients is inadequate and there is a tendency of direct association between lack of blood glucose control and lack of dyslipidemia control, in addition to the association with other cardiovascular risk factors, such as diastolic hypertension and smoking. This worsened control might be related to the plateau in the descending curve of mortality, and investments in this regard can improve the cardiovascular health in diabetic patients.


RESUMO OBJETIVO O diabetes é importante causa de mortalidade cardiovascular. Nos últimos anos, a mortalidade diminuiu substancialmente, mais em diabéticos do que em não diabéticos, em grande parte devido ao controle de outros fatores de risco cardiovasculares. Nosso estudo tem como objetivo analisar o controle de dislipidemia em duas coortes de diabéticos. MÉTODOS Foram estudados pacientes de duas coortes distintas, sendo 173 pacientes do BHS (Brasília Heart Study) e 222 pacientes do BDS (Brazilian Diabetes Study). Os dados sobre controle de dislipidemia foram estudados nas duas populações diferentes. Todos os pacientes eram diabéticos. RESULTADOS Há diferenças significativas em relação às comorbidades entre os grupos de LDL-C no BDS. A média de hemoglobina glicada é de 8,2 no grupo com LDL-C > 100, comparado com 7,7 e 7,5 nos grupos 70-100 e < 70, respectivamente (p = 0,024). Há maior porcentagem de pacientes hipertensos com LDL entre 70-100 (63,9%), quando comparado aos grupos < 70 e > 100 (54,3% e 54,9%, respectivamente; p = 0,005). A pressão diastólica é mais elevada no grupo com LDL > 100, com média de 87 mmHg, comparado com 82,6 mmHg e 81,9 mmHg nos grupos 70-100 e < 70, respectivamente (p = 0,019). O grupo com LDL > 100 tem maior porcentagem de tabagistas (8,7%) quando comparado aos grupos com LDL entre 70-100 e < 70 (5,6% e 4,3%, respectivamente; p = 0,015). Há, também, diferença na incidência prévia de coronariopatia. No grupo com LDL < 70, 28,3% dos pacientes já apresentaram infarto prévio, comparados com 11,1% e 10,6% nos grupos 70-100 e > 100, respectivamente (p < 0,001). CONCLUSÃO Os dados do nosso estudo mostram que o controle de dislipidemia em diabéticos é inadequado, e há uma tendência de associação direta entre descontrole glicêmico e descontrole de dislipidemia, além de associação com outros fatores de risco cardiovascular, como hipertensão diastólica e tabagismo. Esse pior controle pode estar relacionado ao platô no descenso da curva de mortalidade, e o investimento nesse quesito pode melhorar a saúde cardiovascular dos diabéticos.

ABSTRACT

Statins are a widely prescribed class of medications that inhibit similar pathways as the anti-resorptive bisphosphonate drugs. Statins target the mevalonate pathway by blocking HMG-CoA reductase. Several recent meta-analyses concluded statins are osteoprotective in the general population. Here we present current literature exploring the mechanisms underlying the putative osteoprotective effects of statins. We also review recent clinical studies, ranging from observational cohort studies to randomized clinical trials, testing the effect of statins on bone health in various populations. (AU)


Las estatinas son un grupo de drogas prescriptas en forma habitual, con la capacidad de bloquear vías de señalización similares a las inhibidas por los amino-bisfosfonatos. Las estatinas inhiben la vía del mevalonato, a través del bloqueo de diferentes enzimas. Varios metaanálisis recientes llevaron a la conclusión de que las estatinas tienen capacidad osteoprotectora en la población general. En esta revisión presentamos la literatura actual describiendo los mecanismos que subyacen en el potencial efecto osteoprotector de las estatinas, como así también estudios observacionales y clínicos aleatorizados sobre el efecto de estatinas en la salud ósea en diversas poblaciones.

ABSTRACT

Abstract During the last decade, different studies have converged to evidence the high prevalence of comorbidities in subjects with psoriasis. Although a causal relation has not been fully elucidated, genetic relation, inflammatory pathways and/or common environmental factors appear to be underlying the development of psoriasis and the metabolic comorbidities. The concept of psoriasis as a systemic disease directed the attention of the scientific community in order to investigate the extent to which therapeutic interventions influence the onset and evolution of the most prevalent comorbidities in patients with psoriasis. This study presents scientific evidence of the influence of immunobiological treatments for psoriasis available in Brazil (infliximab, adalimumab, etanercept and ustekinumab) on the main comorbidities related to psoriasis. It highlights the importance of the inflammatory burden on the clinical outcome of patients, not only on disease activity, but also on the comorbidities. In this sense, systemic treatments, whether immunobiologicals or classic, can play a critical role to effectively control the inflammatory burden in psoriatic patients.

ABSTRACT

ABSTRACT Purpose: Female sexual dysfunction is a complex and common condition that affects women, and the relationship between sexual function and dyslipidemia is poorly studied. This study aims to assess this relationship in the reproductive life women in the menacme who use combined oral contraceptives (COCs) . Methods: A total of 49 healthy women who were sexually active received COC pills that contained ethinylestradiol 30 mcg (EE30) plus levonorgestrel 150 mcg (LNG150). The women were divided into two groups according to their lipid profiles. Dyslipidemia was defined as a high-density lipoprotein (HDL) level < 50 mg/dL or a low-density lipoprotein (LDL) level > 130 mg/dL. Sexual function was assessed using the Female Sexual Function Index (FSFI) Questionnaire. Lipid and lipoprotein parameters were obtained at baseline and after the sixth cycle. Results: After six cycles of the COCs, the total cholesterol and LDL cholesterol levels in the women with a LDL level > 130 mg/dL decreased by 14.7% and 22.1% respectively. In the women with a HDL level < 50 mg/dL at baseline, the HDL level increased by 15.5% at the end of the study. The arousal and orgasm domains and the FSFI total scores significantly increased in women with and without dyslipidemia. The desire and satisfaction domains increased only in the group without dyslipidemia at the end of the treatment period. Conclusions: The EE30/LNG150 formulation increased the sexual function and it was only positively correlated with the HDL cholesterol level. These data indicated a low correlation between sexual function and the changes in the lipid and lipoprotein metabolism.


RESUMO Objetivo: Disfunção sexual feminina é uma condição complexa acomete as mulheres, e a relação entre a função sexual e a dislipidemia é muito pouco estudada. Este estudo objetivou avaliar esta relação em mulheres na menacme que fazem uso de contraceptivos orais combinados (COCs). Métodos: Um total de 49 mulheres saudáveis com vida sexual ativa receberam pílulas anticoncepcionais contendo etinilestradiol 30 mcg (EE30) associado a levonorgestrel 150 mcg (LNG150). As mulheres foram divididas em dois grupos, de acordo com o perfil lipídico. Dislipidemia foi definida como nível de lipoproteína de alta densidade (HDL) < 50 mg/dL, ou nível de lipoproteína de baixa densidade (LDL) > 130 mg/dL. A função sexual feminina foi avaliada utilizando o questionário de Índice de Função Sexual Feminina (IFSF). O IFSF e os parâmetros lipídicos e lipoproteicos foram obtidos no início e após o sexto ciclo do estudo. Resultados: Após seis ciclos de uso dos COCs, as mulheres com LDL > 130 mg/dL, tiveram redução dos níveis de colesterol total e colesterol LDL de 14,7% e 22,1% respectivamente. Nas mulheres com níveis HDL < 50 mg/dL no momento basal, o nível de HDL aumentou 15,5% ao final do estudo. Os domínios de excitação, orgasmo e os escores totais do IFSF aumentaram significativamente nas mulheres com e sem dislipidemia. Os domínios de desejo e satisfação aumentaram no final do período de tratamento exclusivamente no grupo sem dislipidemia. Conclusões: A formulação EE30/LNG150 aumentou a função sexual das mulheres, sendo positivamente correlata somente com os níveis de colesterol HDL. Estes achados demonstram baixa correlação entre a função sexual e as alterações no metabolismo lipídico e lipoproteico.

ABSTRACT

Resumo A utilização de medicamentos para tratamento das dislipidemias é relevante no controle das doenças cardiovasculares. O objetivo deste artigo é analisar a prevalência, a utilização e a participação do setor público no fornecimento de medicamentos para as pessoas a partir de 40 anos em farmacoterapia de controle das dislipidemias, residentes em um município da região Sul do Brasil. Estudo transversal de base populacional. Foram entrevistados no domicilio 1180 indivíduos a partir de 40 anos residentes em Cambé/PR, dos quais 967 realizaram exames laboratoriais. A prevalência de dislipidemias foi de 69,2%, dos quais 16,1% utilizavam medicamentos. Entre os indivíduos em tratamento para as dislipidemias, 22,2% apresentaram resultados de exames adequados. Os fármacos hipolipemiantes mais utilizados foram sinvastatina (81,5%) e bezafibrato (6,5%), obtidos principalmente por pagamento direto em farmácias e drogarias privadas (52,2%) e serviços próprios do SUS (33,6%). Em nível populacional a prevalência das dislipidemias foi elevada, o seu controle baixo, com menor participação do setor público no fornecimento dos medicamentos do que a aquisição mediante pagamento direto em farmácias e drogarias privadas, sugerindo alcance limitado das políticas públicas de controle das dislipidemias.

This article aims to analyze the prevalence, the use and the participation of the public sector in the supply of medication for adults aged 40 years and above using pharmacotherapy for dyslipidemia control living in a city in the southern region of Brazil. A cross-sectional, population-based study was conducted. Household interviews were staged with 1180 individuals aged over 40 living in Cambé, State of Paraná, of which 967 took laboratory examinations. The prevalence of dyslipidemia was 69.2%, of which 16.1% were taking medication. Among individuals undergoing treatment for dyslipidemia, 22.2% had adequate test results. Lipid-lowering medication used were simvastatin (81.5%) and bezafibrate (6.5%), mainly obtained by direct payment to private pharmacies and drug stores (52.2%) and NHS services (33.6%). A high prevalence of dyslipidemias was observed in population terms, together with a low level of dyslipidemia control and low participation of the public sector regarding the supply of medication compared to acquisition through direct payment for medication in private pharmacies. These results suggest a limited range of public policy for control of dyslipidemia.

ABSTRACT

PURPOSE: To address the effects of fructooligosaccharides (FOS) intake on serum cholesterol levels. METHODS: We performed a search for scientific articles in MEDLINE database from 1987 to 2014, using the following English keywords: fructooligosaccharides; fructooligosaccharides and cholesterol. A total of 493 articles were found. After careful selection and exclusion of duplicate articles 34 references were selected. Revised texts were divided into two topics: "FOS Metabolism" and "FOS effects on plasma cholesterol." RESULTS: The use of a FOS diet prevented some lipid disorders and lowered fatty acid synthase activity in the liver in insulin-resistant rats. There was also reduction in weight and total cholesterol in beagle dogs on a calorie-restricted diet enriched with short-chain FOS. Another study found that 2g FOS daily consumption increased significantly serum HDL cholesterol levels but did not ensure a significant reduction in levels of total cholesterol and triglycerides.. Patients with mild hypercholesterolemia receiving short-chain FOS 10.6g daily presented no statistically significant reduction in serum cholesterol levels. However, when FOS was offered to patients that changed their lifestyle, the reduction of LDL cholesterol and steatosis was higher. CONCLUSIONS: Fructooligosaccharides intake may have a beneficial effect on lipid metabolism and regulation of serum cholesterol levels in individuals that change their lifestyle. FOS supplementation use in diets may therefore be a strategy for lowering cholesterol. .

ABSTRACT

Altered cholesterol levels in the blood or dyslipidemia is a major modifiable risk factor for CVD and is closely associated with the pathophysiology of CVD. Asians, particularly Indians, have a unique pattern of dyslipidemia; with lower HDL cholesterol, increased triglyceride levels and higher proportion of small dense LDL cholesterol, with characteristic centripetal obesity. ‘Statins’ belong to the group of 3-hydroxy-3-methylglutaryl Coenzyme A reductase inhibitors that have been shown to reduce levels of total and LDL cholesterol. Study Objective: To evaluate the lipid lowering efficacy and safety of Rosuvastatin in Indian dyslipidemics in routine clinical practice by measuring the percent change in Total Cholesterol, LDL, TG and HDL over a period of 16 weeks. Methodology : This was a multicentric, open-labeled, post-marketing surveillance study. A committee of key opinion leaders was formed. A total of 1200 doctors were approached of whom 800 provided us with subject data. Each participating doctor was given case report forms and requested to recruit patients according to the inclusion and exclusion criteria. Lipid profile of each recruited patient was done before initiating therapy and at the end of 4 months. Rosuvastatin was given at a dose of either 5mg/ 10mg OD for 4 months. Results : A total of 11, 656 subjects were recruited into this study out of which 10, 410 complete case report forms were considered (n=10410). The study included 65% males and 35% females. Majority of the subjects were in the age group of 46-55years (35.2%) and 56-65 years (29.4%). In this study, the total cholesterol (TC), LDL-C, Triglycerides (TG) has significantly decreased by 46.13%, 53.74% and 41.93% respectively. Also the HDLC levels increased by 26.84%, thereby, indicating a significant change in the levels of all the dyslipidemic indicators. With the reported number of adverse events (n=4) related to Rosuvastatin, it is evident that the drug is safe and tolerable. There were no significant changes observed in the liver and renal function tests with Rosuvastatin reiterating their safety. Conclusion : Rosuvastatin has shown greater efficacy in lowering LDL cholesterol and non-HDL-cholesterol concentrations. It has been shown to enable more patients to reach their LDL cholesterol goals and to do so with an acceptable safety profile.

ABSTRACT

Ginkgo biloba extract (GbE) has been indicated as an efficient medicine for the treatment of diabetes mellitus type 2. It remains unclear if its effects are due to an improvement of the insulin signaling cascade, especially in obese subjects. The aim of the present study was to evaluate the effect of GbE on insulin tolerance, food intake, body adiposity, lipid profile, fasting insulin, and muscle levels of insulin receptor substrate 1 (IRS-1), protein tyrosine phosphatase 1B (PTP-1B), and protein kinase B (Akt), as well as Akt phosphorylation, in diet-induced obese rats. Rats were fed with a high-fat diet (HFD) or a normal fat diet (NFD) for 8 weeks. After that, the HFD group was divided into two groups: rats gavaged with a saline vehicle (HFD+V), and rats gavaged with 500 mg/kg of GbE diluted in the saline vehicle (HFD+Gb). NFD rats were gavaged with the saline vehicle only. At the end of the treatment, the rats were anesthetized, insulin was injected into the portal vein, and after 90s, the gastrocnemius muscle was removed. The quantification of IRS-1, Akt, and Akt phosphorylation was performed using Western blotting. Serum levels of fasting insulin and glucose, triacylglycerols and total cholesterol, and LDL and HDL fractions were measured. An insulin tolerance test was also performed. Ingestion of a hyperlipidic diet promoted loss of insulin sensitivity and also resulted in a significant increase in body adiposity, plasma triacylglycerol, and glucose levels. In addition, GbE treatment significantly reduced food intake and body adiposity while it protected against hyperglycemia and dyslipidemia in diet-induced obesity rats. It also enhanced insulin sensitivity in comparison to HFD+V rats, while it restored insulin-induced Akt phosphorylation, increased IRS-1, and reduced PTP-1B levels in gastrocnemius muscle. The present findings suggest that G. biloba might be efficient in preventing and treating obesity-induced insulin signaling impairment.

ABSTRACT

JUSTIFICATIVA E OBJETIVO: As dislipidemias são uma das principais causas de morbidade e mortalidade por doenças car- diovasculares. O objetivo deste estudo foi avaliar o efeito hipo- lipemiante do extrato seco de Solanum melongena L. (berinjela) versus placebo e sinvastatina, em pacientes com hipercolesterole- mia. MÉTODOS: Foi realizado um ensaio clínico randomiza- do com 36 indivíduos adultos, hipercolesterolêmicos, alocados em quatro grupos: Grupo 1, ao qual foi administrado placebo (n=10); Grupo 2, que recebeu extrato seco de berinjela (n=10; colesterol total=200 a 239mg/dL); Grupo 3 que também recebeu extrato seco de berinjela (n=9; colesterol total ?240mg/dL); e Grupo 4, que foi tratado com sinvastatina (n=7; colesterol total ?240mg/dL). Foram realizados exames laboratoriais na linha de base, após 30, 60 e 90 dias de tratamento. RESULTADOS: Houve redução significativa de colesterol total e LDL no Grupo 4 (p<0,001 e p=0,001, respectivamente). Os demais valores e grupos não apresentaram diferença no tratamento. CONCLU- SÃO: O extrato seco de Solanum melongena L. não apresentou diferença estatisticamente significativa na redução dos níveis do colesterol total, frações e triglicerídeos quando comparado ao uso de sinvastatina ou placebo.(AU)


BACKGROUND AND OBJETIVE: Dyslipidemia is the leading cause of morbidity and mortality from cardiovascular disease. The aim of this study was to evaluate the lipid-lowering effect of dry extracts of Solanum melongena L. (eggplant) versus placebo and simvastatin in patients with hypercholesterolemia. METHODS: A randomized clinical trial was performed on 36 adult subjects with hypercholesterolemia. They were divided into four groups: Group 1, which was treated with placebo (n=10); Group 2, that received dry extract of eggplant (n=10; total cholesterol=200 to 239mg/dL); Group 3, that also received dry extract of eggplant (n=9; total cholesterol ?240mg/dL) and Group 4, treated with simvastatin (n=7; total cholesterol ?240mg/dL). Laboratory tests were carried out at baseline and 30, 60 and 90 days after the start of treatment. RESULTS: There was a significant reduction in total cholesterol and LDL in Group 4 (p<0.001 and 0.001, respectively). There was no significant difference in cholesterol levels in the other groups because of treatment. CONCLUSION: The dry extract of Solanum melongena L. showed no statistically significant difference in reducing the levels of total cholesterol, fractions, and triglycerides, when compared with the use of simvastatin or placebo.(AU)

ABSTRACT

Ursolic acid (UA) is a pentacyclic triterpenoid compound that naturally occurs in fruits, leaves and flowers of medicinal herbs. This study investigated the dose-response efficacy of UA (0.01 and 0.05%) on glucose metabolism, the polyol pathway and dyslipidemia in streptozotocin/nicotinamide-induced diabetic mice. Supplement with both UA doses reduced fasting blood glucose and plasma triglyceride levels in non-obese type 2 diabetic mice. High-dose UA significantly lowered plasma free fatty acid, total cholesterol and VLDL-cholesterol levels compared with the diabetic control mice, while LDL-cholesterol levels were reduced with both doses. UA supplement effectively decreased hepatic glucose-6-phosphatase activity and increased glucokinase activity, the glucokinase/glucose-6-phosphatase ratio, GLUT2 mRNA levels and glycogen content compared with the diabetic control mice. UA supplement attenuated hyperglycemia-induced renal hypertrophy and histological changes. Renal aldose reductase activity was higher, whereas sorbitol dehydrogenase activity was lower in the diabetic control group than in the non-diabetic group. However, UA supplement reversed the biochemical changes in polyol pathway to normal values. These results demonstrated that low-dose UA had preventive potency for diabetic renal complications, which could be mediated by changes in hepatic glucose metabolism and the renal polyol pathway. High-dose UA was more effective anti-dyslipidemia therapy in non-obese type 2 diabetic mice.

ABSTRACT

Objective: To identify the adherence rate of a statin treatment and possible related factors in female users from the Unified Health System. Method: Seventy-one women were evaluated (64.2 ± 11.0 years) regarding the socio-economic level, comorbidities, current medications, level of physical activity, self-report of muscular pain, adherence to the medical prescription, body composition and biochemical profile. The data were analyzed as frequencies, Chi-Squared test, and Mann Whitney test (p<0.05). Results: 15.5% of women did not adhere to the medical prescription for the statin treatment, whose had less comorbidities (p=0.01), consumed less quantities of medications (p=0.00), and tended to be younger (p=0.06). Those patients also presented higher values of lipid profile (CT: p=0.01; LDL-c: p=0.02). Musculoskeletal complains were not associated to the adherence rate to the medication. Conclusion: The associated factors to adherence of dyslipidemic women to statin medical prescription were age, quantity of comorbidities and quantity of current medication.

ABSTRACT

High fat diet group showed a significant rise in serum and hepatic total cholesterol, triglyceride and atherogenic index which are major biomarkers of dyslipidemia and cardiovascular risk. The liver function markers, lipid peroxidation and proinflammatory cytokine levels were elevated in high fat diet group whereas antioxidant levels significantly reduced. These findings manifest hepatic damage which was further confirmed by histological findings. Quercetin and β-sitosterol though structurally different yet both ameliorate the sickening changes in different mechanism. The current investigation is perhaps the first report of the mechanistic role of two polyphenols over dyslipidemia and subsequent hepatotoxicity.
