RESUMO

PURPOSE OF REVIEW: Referral to nutrition care providers in the USA such as registered dietitian nutritionists (RDNs) for medical nutrition therapy (MNT) remains low. We summarize research on the effectiveness of MNT provided by dietitians versus usual care in the management of adults with dyslipidemia. Improvements in lipids/lipoproteins were examined. If reported, blood pressure (BP), fasting blood glucose (FBG) glycated hemoglobin (A1c), body mass index (BMI), and cost outcomes were also examined. RECENT FINDINGS: The synthesis of three systematic reviews included thirty randomized controlled trials. Multiple MNT visits (3-6) provided by dietitians, compared with usual care, resulted in significant improvements in total cholesterol (mean range: - 4.64 to - 20.84 mg/dl), low-density lipoprotein cholesterol (mean range: - 1.55 to - 11.56 mg/dl), triglycerides (mean range: - 15.9 to - 32.55 mg/dl), SBP (mean range: - 4.7 to - 8.76 mm Hg), BMI (mean: - 0.4 kg/m2), and A1c (- 0.38%). Cost savings from MNT were attributed to a decrease in medication costs and improved quality of life years (QALY). Multiple MNT visits provided by dietitians compared with usual care improved lipids/lipoproteins, BP, A1c, weight status, and QALY with significant cost savings in adults with dyslipidemia and justify a universal nutrition policy for equitable access to MNT.

RESUMO

Cardiovascular disease (CVD) is a leading cause of mortality in the United States. Many primary risk factors, such as dyslipidemia and blood pressure, are modifiable with diet and lifestyle interventions. Therefore, the objective of this systematic review and meta-analysis was to evaluate the effectiveness of medical nutrition therapy (MNT) interventions provided by registered dietitian nutritionists (RDN) or international equivalents, compared to usual care or no MNT, on lipid profile and blood pressure (secondary outcome) in adults with dyslipidemia. The databases MEDLINE, CINAHL, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews were searched for randomized controlled trials (RCTs) published between January 2005 and July 2021. Meta-analyses were performed using a random-effects model for lipid outcomes (seven RCTs, n=838), systolic blood pressure (SBP) (three RCTs, n=308), and diastolic blood pressure (DBP) (two RCTs, n=109). Compared to usual care or no intervention, MNT provided by RDNs improved total cholesterol (total-C) [mean difference (95% CI): -20.84 mg/dL (-40.60, -1.07), P=0.04]; low-density lipoprotein cholesterol (LDL-C) [-11.56 mg/dL (-21.10, -2.03), P=0.02]; triglycerides (TG) [-32.55 mg/dL (-57.78, -7.32), P=0.01];; and SBP [ -8.76 mm Hg (-14.06 lower to -3.45) P<0.01].High-density lipoprotein cholesterol (HDL-C) [1.75 mg/dl (-1.43, 4.92), P=0.28] and DBP [-2.9 mm Hg (-7.89 to 2.09), P=0.25] were unchanged. Certainty of evidence was moderate for total-C, LDL-C, and TG, and low for HDL-C, SBP, and DBP. In conclusion, in adults with dyslipidemia, MNT interventions provided by RDNs are effective for improving serum lipids/lipoproteins and SBP levels.

RESUMO

Coronary heart disease (CHD) is the main cause of death and morbidity in the world. Childhood is a critical period during which atherosclerosis may begin to develop; in the presence of familial hypercholesterolaemia (FH), the lifelong elevation of LDL cholesterol levels greatly accelerates atherosclerosis. Lowering LDL-C levels is associated with a well-documented reduction in cardiovascular disease risk. Current guidelines support the dietary and lifestyle approach as the primary strategy of intervention in children and adolescents with FH. Nutraceuticals (functional foods or dietary supplements of plant or microbial origin) are included in the EU guidelines as lifestyle interventions and may provide an additional contribution in reducing LDL levels when pharmacological therapy is not yet indicated. Meta-analyses of randomised clinical trials have demonstrated that the same nutraceuticals improve lipid profile, including lowering LDL-C, total cholesterol and triglyceride levels. In this narrative review, starting from current scientific evidence, we analyse the benefits and limitations of the nutraceuticals in children and adolescents with dyslipidaemia, and we try to evaluate their use and safety in clinical practice.

RESUMO

Dyslipidemia is a risk factor for atherosclerotic cardiovascular disease and requires proactive management. This study aimed to investigate the association between care continuity and the outcomes of patients with dyslipidemia. We conducted a retrospective cohort study on patients with dyslipidemia by employing the Korea National Health Insurance claims database during the period 2007-2018. The Continuity of Care Index (COCI) was used to measure continuity of care. We considered incidence of atherosclerotic cardiovascular disease as a primary outcome. A Cox's proportional hazards regression model was used to quantify risks of primary outcome. There were 236,486 patients newly diagnosed with dyslipidemia in 2008 who were categorized into the high and low COC groups depending on their COCI. The adjusted hazard ratio for the primary outcome was 1.09 times higher (95% confidence interval: 1.06-1.12) in the low COC group than in the high COC group. The study shows that improved continuity of care for newly-diagnosed dyslipidemic patients might reduce the risk of atherosclerotic cardiovascular disease.

RESUMO

Dyslipidaemias result in the deposition of cholesterol and lipids in the walls of blood vessels, chronic inflammation and the formation of atherosclerotic plaques, which impede blood flow and (when they rupture) result in acute ischaemic episodes. Whilst recent years have seen enormous success in the reduction of cardiovascular risk using conventional pharmaceuticals, there is increasing interest amongst patients and practitioners in the use of nutraceuticals to combat dyslipidaemias and inflammation in cardiovascular disease. Nutraceutical is a portmanteau term: 'ceutical' indicate pharmaceutical-grade preparations, and 'nutra' indicates that the products contain nutrients from food. Until relatively recently, little high-quality evidence relating to the safety and efficacy of nutraceuticals has been available to prescribers and policymakers. However, as a result of recent randomised-controlled trials, cohort studies and meta-analyses, this situation is changing, and nutraceuticals are now recommended in several mainstream guidelines relating to dyslipidaemias and atherosclerosis. This article will summarise recent clinical-practice guidance relating to the use of nutraceuticals in this context and the evidence which underlies them. Particular attention is given to position papers and recommendations from the International Lipid Expert Panel (ILEP), which has produced several practical and helpful recommendations in this field.

RESUMO

The dietary supplement, trans-resveratrol and hesperetin combination (tRES-HESP), induces expression of glyoxalase 1, countering the accumulation of reactive dicarbonyl glycating agent, methylglyoxal (MG), in overweight and obese subjects. tRES-HESP produced reversal of insulin resistance, improving dysglycemia and low-grade inflammation in a randomized, double-blind, placebo-controlled crossover study. Herein, we report further analysis of study variables. MG metabolism-related variables correlated with BMI, dysglycemia, vascular inflammation, blood pressure, and dyslipidemia. With tRES-HESP treatment, plasma MG correlated negatively with endothelial independent arterial dilatation (r = -0.48, p < 0.05) and negatively with peripheral blood mononuclear cell (PBMC) quinone reductase activity (r = -0.68, p < 0.05)-a marker of the activation status of transcription factor Nrf2. For change from baseline of PBMC gene expression with tRES-HESP treatment, Glo1 expression correlated negatively with change in the oral glucose tolerance test area-under-the-curve plasma glucose (ΔAUGg) (r = -0.56, p < 0.05) and thioredoxin interacting protein (TXNIP) correlated positively with ΔAUGg (r = 0.59, p < 0.05). Tumor necrosis factor-α (TNFα) correlated positively with change in fasting plasma glucose (r = 0.70, p < 0.001) and negatively with change in insulin sensitivity (r = -0.68, p < 0.01). These correlations were not present with placebo. tRES-HESP decreased low-grade inflammation, characterized by decreased expression of CCL2, COX-2, IL-8, and RAGE. Changes in CCL2, IL-8, and RAGE were intercorrelated and all correlated positively with changes in MLXIP, MAFF, MAFG, NCF1, and FTH1, and negatively with changes in HMOX1 and TKT; changes in IL-8 also correlated positively with change in COX-2. Total urinary excretion of tRES and HESP metabolites were strongly correlated. These findings suggest tRES-HESP counters MG accumulation and protein glycation, decreasing activation of the unfolded protein response and expression of TXNIP and TNFα, producing reversal of insulin resistance. tRES-HESP is suitable for further evaluation for treatment of insulin resistance and related disorders.

RESUMO

SCOPE: Obesity is a common disease worldwide and there is an urgent need for strategies to preventing obesity. METHODS AND RESULTS: The anti-obesity effect and mechanism of Ligilactobacillus salivarius LCK11 (LCK11) is studied using a C57BL/6J male mouse model in which obesity is induced by a high-fat diet (HFD). Results show that LCK11 can prevent HFD-induced obesity, reflected as inhibited body weight gain, abdominal and liver fat accumulation and dyslipidemia. Analysis of its mechanism shows that on the one hand, LCK11 can inhibit food intake through significantly improving the transcriptional and translational levels of peptide YY (PYY) in the rectum, in addition to the eventual serum PYY level; this is attributed to the activation of the toll-like receptor 2/nuclear factor-κB signaling pathway in enteroendocrine L cells by the peptidoglycan of LCK11. On the other hand, LCK11 supplementation effectively reduces the Firmicutes/Bacteroidetes ratio and shifts the overall structure of the HFD-disrupted gut microbiota toward that of mice fed on a low-fat diet; this also contributes to preventing obesity. CONCLUSION: LCK11 shows the potential to be used as a novel probiotic for preventing obesity by both promoting PYY secretion to inhibit food intake and regulating gut microbiota.

RESUMO

BACKGROUND AND AIMS: A relevant role is emerging for functional foods in cardiovascular prevention. The aim of this study was to assess the effect of a nutraceutical multitargeted approach on lipid profile and inflammatory markers along with vascular remodelling in a cohort of dyslipidemic subjects without history of cardiovascular (CV) disease. METHODS AND RESULTS: We enrolled 25 subjects (mean age 48.2 years) with low to moderate CV risk profile and total cholesterol (TC) levels between 150 and 250 mg/dl. The patients were assigned to receive for one year a tablet/die of a nutraceutical combination containing red yeast rice (RYR) extract (Monacolin 3 mg/tablet) and coenzyme Q10 (30 mg/tablet). Treatment with the nutraceutical compounds led to a significant reduction of TC (from 227 to 201 mg/dl, p < 0.001), LDL-c (from 150 to 130 mg/dl, p = 0.001), triglycerides (from 121 to 109 mg/dl, p = 0.013), non-HDL-cholesterol (from 168 to 141 mg/dl, p < 0.001), hs-CRP (from 1.74 to 1.20 mg/l, p = 0.015), and osteoprotegerin (from 1488 to 1328 pg/ml, p = 0.045). Levels of HDL-c, Lp(a), glucose, liver enzyme, CPK, or creatinine did not change over time. An ultrasound study was performed to assess changes in mean carotid intima-media thickness (IMT) and maximum IMT (M-MAX) as well as modification in local carotid stiffness by means of determining the carotid compliance coefficient (CC) and distensibility coefficient (DC). At the end of the treatment, we observed small but significant reductions in both mean-IMT (from 0.62 to 0.57 mm, p = 0.022) and M-MAX (from 0.79 to 0.73 mm, p = 0.002), and an improvement in carotid elasticity (DC from 22.4 to 24.3 × 10-3/kPa, p = 0.006 and CC from 0.77 to 0.85 mm2/kPa, p = 0.019). CONCLUSIONS: A long-term treatment with a combination of RYR and coenzyme Q10 showed lipid-lowering activity along with a reduction of inflammatory mediators and an improvement of vascular properties in young subjects with a low-to-moderate CV risk profile.

RESUMO

INTRODUCTION: The aim of the present study was to verify the effects of a Pilates training on total cholesterol (TC), triglycerides (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), glucose and C-reactive protein (CRP) levels, as well as on functionality of postmenopausal women with dyslipidemia. METHOD: This randomized study involved 35 sedentary women with dyslipidemia, aged between 60 and 75 years. One group participated in a Pilates exercises training with two to four weekly sessions during 10 weeks (Pilates group, n = 20) and the other group did not perform any intervention (control group, n = 6). Biochemical analyses and functionality parameters were measured before and after the 10 weeks. RESULTS: No significant differences were observed in TC, TG, LDL and HDL for both groups. Regarding glucose and CRP levels, significant reductions were observed in both groups after the intervention period. In functional parameters, both groups significantly increased their 30-s chair stand test values. On the other hand, only the Pilates group presented significant increments in the 6-min walk test (p < 0.05). CONCLUSION: Pilates training did not change lipid or lipoprotein levels, but improved cardiorespiratory fitness of elderly women with dyslipidemia.

RESUMO

BACKGROUND: This study aimed to investigate the prevalence, awareness, treatment, and control rates of dyslipidemia and identify the predictors of optimal control (low-density lipoprotein cholesterol < 100 mg/dL) among patients with diabetes mellitus (DM). METHODS: A cross-sectional study was conducted using the representative Korea National Health and Nutrition Examination Survey (2014-2018). Overall, 4311 patients with DM, aged ≥19 years, and without cardiovascular diseases were selected, and the prevalence, awareness, treatment, and control rates of dyslipidemia were calculated. Univariate and multivariate logistic regression analyses were conducted to evaluate the factors influencing the optimal control of dyslipidemia. RESULTS: Dyslipidemia was prevalent in 83.3% of patients with DM, but the awareness and treatment rates were 36.5 and 26.9%, respectively. The control rate among all patients with dyslipidemia was 18.8%, whereas it was 61.1% among those being treated. Prevalence and awareness rates were also significantly higher in women than in men. Dyslipidemia was most prevalent in those aged 19-39 years, but the rates of awareness, treatment, and control among all patients with dyslipidemia in this age group were significantly lower than those in other age groups. The predictors of optimal control were age ≥ 40 years [range 40-49 years: adjusted odds ratio (aOR) 3.73, 95% confidence interval (CI) 1.43-9.72; 50-59 years: aOR 6.25, 95% CI 2.50-15.65; 60-69 years: aOR 6.96, 95% CI 2.77-17.44; 70-79 years: aOR 9.21, 95% CI 3.58-23.74; and ≥ 80 years: aOR 4.43, 95% CI 1.60-12.27]; urban living (aOR 1.44, 95% CI 1.15-1.80); higher body mass index (aOR 1.27, 95% CI 1.13-1.42); lower glycated hemoglobin levels (aOR 0.71, 95% CI 0.67-0.76); hypertension (aOR 1.53, 95% CI 1.22-1.92); poorer self-rated health status (aOR 0.72, 95% CI 0.62-0.84); and receiving regular health check-ups (aOR 1.58, 95% CI 1.25-2.00). CONCLUSIONS: Most patients with DM were diagnosed with dyslipidemia, but many were unaware of or untreated for their condition. Therefore, their control rate was suboptimal. Thus, by understanding factors influencing optimal control of dyslipidemia, physicians should make more effort to encourage patients to undergo treatment and thus, adequately control their dyslipidemia.

RESUMO

The 2021 guidelines primary panel selected clinically relevant questions and produced updated recommendations, on the basis of important new findings that have emerged since the 2016 guidelines. In patients with clinical atherosclerosis, abdominal aortic aneurysm, most patients with diabetes or chronic kidney disease, and those with low-density lipoprotein cholesterol ≥ 5 mmol/L, statin therapy continues to be recommended. We have introduced the concept of lipid/lipoprotein treatment thresholds for intensifying lipid-lowering therapy with nonstatin agents, and have identified the secondary prevention patients who have been shown to derive the largest benefit from intensification of therapy with these agents. For all other patients, we emphasize risk assessment linked to lipid/lipoprotein evaluation to optimize clinical decision-making. Lipoprotein(a) measurement is now recommended once in a patient's lifetime, as part of initial lipid screening to assess cardiovascular risk. For any patient with triglycerides ˃ 1.5 mmol/L, either non-high-density lipoprotein cholesterol or apolipoprotein B are the preferred lipid parameter for screening, rather than low-density lipoprotein cholesterol. We provide updated recommendations regarding the role of coronary artery calcium scoring as a clinical decision tool to aid the decision to initiate statin therapy. There are new recommendations on the preventative care of women with hypertensive disorders of pregnancy. Health behaviour modification, including regular exercise and a heart-healthy diet, remain the cornerstone of cardiovascular disease prevention. These guidelines are intended to provide a platform for meaningful conversation and shared-decision making between patient and care provider, so that individual decisions can be made for risk screening, assessment, and treatment.

RESUMO

Atherosclerosis is a multifactorial disease influenced by genetics, lifestyle and environmental factors. Despite therapeutic advances that reduce the risk of cardiovascular events, atherosclerosis-related diseases remain the leading cause of mortality worldwide. Precise targeting of genes involved in lipoprotein metabolism is an emerging approach for atherosclerosis prevention and treatment. This article focuses on the latest developments, clinical potential and current challenges of monoclonal antibodies, vaccines and genome/transcriptome modification strategies, including antisense oligonucleotides, genome/base editing and gene therapy. Multiple lipid lowering biological therapies have already been approved by the FDA with impressive results to date, while many more promising targets are being pursued in clinical trials or pre-clinical animal models.

RESUMO

This study was conducted to assess the protective effect of extract of match (EM) on high-fat diet- (HFD-) induced cognitive deficits in male C57BL/6 mice. It was found that EM improved glucose tolerance status by measuring OGTT and IPGTT with HFD-induced mice. EM protected behavioral and memory dysfunction in Y-maze, passive avoidance, and Morris water maze tests. Consumption of EM reduced fat mass, dyslipidemia, and inflammation in adipose tissue. Also, EM ameliorated hepatic and cerebral antioxidant systems. EM improved the cerebral cholinergic system by regulating ACh contents and expression of AChE and ChAT. Also, EM restored mitochondrial function in liver and brain tissue. EM attenuated hepatic inflammatory effect, lipid synthesis, and cholesterol metabolism by regulating the protein expression of TNF-α, TNFR1, p-IRS-1, p-JNK, IL-1ß, iNOS, COX-2, HMGCR, PPARγ, and FAS. Finally, EM regulated cognitive function and neuroinflammation in the whole brain, hippocampus, and cerebral cortex by regulating the protein expression of p-JNK, p-Akt, p-tau, Aß, BDNF, IDE, COX-2, and IL-1ß. These findings suggest that EM might be a potential source of functional food to improve metabolic disorder-associated cognitive dysfunction.

RESUMO

Non-alcoholic fatty liver disease (NAFLD) is a manifestation of metabolic syndrome closely linked to dyslipidemia and gut microbiome dysbiosis. Bilberry anthocyanins (BA) have been reported to have preventive effects against metabolic syndrome. This study aimed to investigate the protective effects and mechanisms of BA in a Western diet (WD)-induced mouse model. The results revealed that supplementation with BA attenuated the serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), low-density lipoprotein cholesterol (LDL-c), fat content in liver, 2-thiobarbituric acid reactive substances (TBARS) and α-smooth muscle actin (α-SMA) caused by WD. Furthermore, gut microbiota characterized by 16S rRNA sequencing revealed that BA reduced remarkably the ratio of Firmicutes/Bacteroidetes (F/B) and modified gut microbiome. In particular, BA increased the relative abundance of g_Akkermansia and g_Parabacteroides. Taken together, our data demonstrated that BA might ameliorate WD-induced NAFLD by attenuating dyslipidemia and gut microbiome dysbiosis.

RESUMO

Antiretroviral therapy (ART) increases the risk of cardiometabolic diseases in people living with HIV/AIDS (PLWHA). However, there is a lack of evidence regarding the effectiveness of a nutritional intervention on several cardiometabolic parameters in this population. Therefore, this study aimed to evaluate the effectiveness of two nutritional interventions on several cardiometabolic parameters in PLWHA treated with ART. A parallel randomized clinical trial was performed with PLWHA treated with ART. The participants (n = 88) were divided into two intervention groups: (1) nutritional counseling (n = 44) and (2) individualized dietary prescription (n = 44). The follow-up period was 30 weeks. A reduction in low-density lipoprotein (LDL) was the primary outcome. Secondary outcome variables were reductions in total cholesterol (TC), triglycerides (TG), fasting plasma glucose (FPG), systolic and diastolic blood pressures (SBP and DBP, respectively), waist circumference (WC), body mass index (BMI), and increases in high-density lipoproteins (HDL). A multiple linear regression was used to analyze the effectiveness of the interventions, adjusted for sociodemographic, lifestyle, and clinical characteristics. Sixty-two PLWHA completed the trial (nutritional counseling, n = 32; individualized dietary prescription, n = 30). At follow-up, we observed in the nutritional counseling group significant reductions in SBP (p = 0.036) and DBP (p = 0.001). Significant reductions in FPG (p = 0.008) and DBP (p = 0.023) were found in the individualized dietary prescription group. In the fully adjusted models, significant reductions in LDL, SBP, DBP, and BMI were found in the individualized dietary prescription group. In conclusion, the two investigated nutritional interventions were effective in reducing some cardiometabolic risk factors in PLWHA. However, after adjustments for covariates, the individualized dietary prescription showed significant reductions in the primary outcome and, also, in more cardiometabolic risk factors than the nutritional counseling.

RESUMO

The Chrysanthemum morifolium Ramat (CM) is widely used as a traditional medicine and herbal tea by the Asian population for its health benefits related to obesity. However, compared to the flowers of CM, detailed mechanisms underlying the beneficial effects of its leaves on obesity and dyslipidemia have not yet been elucidated. Therefore, to investigate the lipidomic biomarkers responsible for the pharmacological effects of CM leaf extract (CLE) in plasma of mice fed a high-fat diet (HFD), the plasma of mice fed a normal diet (ND), HFD, HFD plus CLE 1.5% diet, and HFD plus luteolin 0.003% diet (LU) for 16 weeks were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS) combined with multivariate analysis. In our analysis, the ND, HFD, CLE, and LU groups were clearly differentiated by partial least-squares discriminant analysis (PLS-DA) score plots. The major metabolites contributing to this differentiation were cholesteryl esters (CEs), lysophosphatidylcholines (LPCs), phosphatidylcholines (PCs), ceramides (CERs), and sphingomyelins (SMs). The levels of plasma CEs, LPCs, PCs, SMs, and CERs were significantly increased in the HFD group compared to those in the ND group, and levels of these lipids recovered to normal after administration of CLE or LU. Furthermore, changes in hepatic mRNA expression levels involved in the Kennedy pathway and sphingolipid biosynthesis were also suppressed by treatment with CLE or LU. In conclusion, this study examined the beneficial effects of CLE and LU on obesity and dyslipidemia, which were demonstrated as reduced synthesis of lipotoxic intermediates. These results may provide valuable insights towards evaluating the therapeutic effects of CLE and LU and understanding obesity-related diseases.

RESUMO

Cardiovascular diseases (CVDs) are the leading cause of premature deaths globally and in Ukraine. Dyslipidemia is a recognized risk factor for the development of CVD. Therefore, early detection and appropriate management of dyslipidemia are essential for the primary prevention of CVDs. However, currently, there is a lack of Ukraine-specific guideline recommendations focusing on the management of dyslipidemia in individuals with low-to-moderate CV risk, thus creating an urgent need for structured and easily implementable clinical recommendations/guidelines specific to the country. An expert panel of cardiologists, endocrinologists, and family physicians convened in Ukraine in March 2019. The expert panel critically reviewed and analyzed the current literature and put forth the following recommendations for the management of dyslipidemia in individuals with low-to-moderate risk of CVDs specific to Ukraine: (1) family physicians have the greatest opportunities in carrying out primary prevention; (2) lipid-lowering interventions are essential for primary prevention as per guidelines; (3) a number of nutraceuticals and nutraceutical combinations with clinically established lipid-lowering properties can be considered for primary prevention; they also have a suggested role as an alternative therapy for statin-intolerant patients; (4) on the basis of clinical evidence, nutraceuticals are suggested by guidelines for primary prevention; (5) red yeast rice has potent CV-risk-lowering potential, in addition to lipid-lowering properties; (6) in patients with low-to-moderate cardiovascular risk, a nutraceutical combination of low-dose red yeast rice and synergic lipid-lowering compounds can be used as integral part of guideline-recommended lifestyle interventions for effective primary prevention strategy; (7) nutraceutical combination can be used in patients aged 18 to 75+ years; its use is particularly appropriate in the age group of 18-44 years; (8) it is necessary to attract the media (websites, etc.) to increase patient awareness on the importance of primary prevention; and (9) it is necessary to legally separate nutraceuticals from dietary supplements. These consensus recommendations will help physicians in Ukraine effectively manage dyslipidemia in individuals with low-to-moderate CV risk.

RESUMO

Fubrick tea aqueous extract (FTEs) has been reported to improve lipid metabolism and gut microbiota communities in mice and humans. However, it is still unclear how FTEs prevents obesity through gut microbiota, and whether some other regulatory mechanisms are involved in the process. Here, we found that FTEs supplementation effectively alleviated the body weight gain, visceral fat accumulation, dyslipidemia, and impaired glucose tolerance induced by a high-fat diet (HFD), and fecal microbiota transplantation (FMT) from FTEs-treated mice showed similar protective effects as FTEs supplementation in mice fed with a HFD. The results confirmed that gut microbiota played key roles in attenuating HFD-induced fat deposition and metabolic disorder. In particular, FTEs reversed HFD-induced gut microbiota dysbiosis via increasing the relative abundances of Bacteroides, Adlercreutzia, Alistipes, Parabacteroides, and norank_f_Lachnospiraceae, and reducing that of Staphylococcus. Interestingly, FTEs could still alleviate HFD-induced lipid accumulation in mice treated with antibiotics, which had increased relative abundances of Bacteroidetes, Bacteroides, and Bacteroides_uniformis sp. In addition, supplementation with FTEs also modified the serum metabolome, especially the "caffeine metabolism" pathway. Furthermore, FTEs supplementation increased the concentrations of caffeine, theophylline, and theobromine in serum, which were positively correlated with an abundance of norank_f_Lachnospiraceae. Overall, FTEs exerts beneficial effects against obesity induced by HFD, and the underlying mechanism is partially related to the reprogramming of intestinal microbiota, while the metabolism of caffeine in FTEs also played an important role in the process. This study provides a theoretical basis for the further study of the anti-obesity effects of FTEs and the consideration of gut microbiota as a potential target for the treatment of obesity induced by a HFD.

RESUMO

Consumption of foods rich in dietary fiber has attracted considerable attention for lowering blood cholesterol and triglycerides through attenuation of gut microbiome. Diets rich in fiber may provide substrates for microbes to digest and proliferate. In response, products of microbial digestion enter systemic circulation and support host energy homeostasis. In the present study, rats with hypercholesterolemia (HC) were supplemented with probiotics (PB) and Agaricus bisporus mushroom to examine the antidyslipidemia effects. Forty adult rats were divided into five treatment groups. The rats in the control group were fed only a chow maintenance diet (CON; n = 8), whereas an atherogenic diet (chow diet supplemented with 1.5% cholesterol and 0.5% cholic acid) was offered to the remaining rats to induce hypercholesterolemia (HC group; n = 32). Rats developed HC following a 24-day continuous supplementation with the atherogenic diet. From day 25 onward, the HC group was further divided into HC-CON, HC-PB (supplemented with PB at 1 mg/rat/day), HC-AB (supplemented with A. bisporus at 5% of diet), and HC-AB.PB (supplemented with both A. bisporus and PB). After 6 weeks of supplementation, rats were killed to collect blood to determine serum lipid profile, oxidative stress, and for metagenomics analysis of colon contents. Results showed that all supplementations corrected HC-induced oxidative stress. Furthermore, A. bisporus supplementation corrected HC-induced dyslipidemia (P ≤ .05). Blautia and Bifidobacterium were the most dominant bacterial genera in HC-AB and HC-PB groups, respectively. Phylum Firmicutes and class Clostridia predominantly occupied the gut microbiome in all groups. However, no significant differences were observed in microbiome diversity and clustering patterns among study groups. In conclusion, supplementation of A. bisporus mushroom and probiotics can lower oxidative stress and dyslipidemia with partial effects on the phylogenetic makeup in the gut microbiome.
