Cassiae Semen Extract (CSE) shows promise in treating hyperlipidemia, although its underlying mechanisms are not yet fully understood. This study aimed to investigate the effects of CSE on hyperlipidemia in rats and explore the potential mechanisms involved.

Hyperlipidemic rats were induced by a high-fat diet (HFD) and treated with CSE. Serum, liver, and fecal samples were analyzed through biochemical assays, histopathological examination, 16S rRNA sequencing, KEGG pathway analysis, and Western blot.

CSE treatment effectively alleviated biochemical imbalances and tissue damage induced by the HFD. 16S rRNA sequencing revealed that CSE improved gut microbiota dysbiosis and increased microbiota abundance. Pathological analysis showed that CSE reduced hepatic lipid accumulation, mitigating liver damage. KEGG pathway analysis suggested that the beneficial effects of CSE on hyperlipidemia may involve Fc gamma receptor (FcγR)-mediated phagocytosis, with immune activation influencing lipid homeostasis and liver inflammation. Western blot analysis further indicated that CSE may regulate lipid metabolism via Sterol Regulatory Element-Binding Protein-1c (SREBP-1c) and Peroxisome Proliferator-Activated Receptor Alpha (PPARα), while reducing hepatic inflammation through the MAPK signaling pathway.

CSE may ameliorate hyperlipidemia in rats by modulating gut microbiota disorders, lipid metabolism, and FcγR-mediated immune regulation, providing a potential therapeutic approach for diseases associated with metabolic dysfunction and inflammation. However, further in-depth studies are required to fully elucidate these mechanisms.

The etiology of hyperlipidemia is complex, and our understanding of its underlying mechanisms is limited. Effective therapeutic strategies for hyperlipidemia remain elusive. This study aimed to confirm the effect of curcumin on hyperlipidemia treatment and elucidate the precise mechanism. A high-fat diet-induced hyperlipidemia model using C57BL/6J mice and HaCaT cells was established. Co-immunoprecipitation and immunofluorescence were performed to detect protein interactions, and immunoprecipitation coupled with Western blotting was used to assess protein succinylation. 40 μM of curcumin administration promoted cell viability, increased the levels of glutathione peroxidase, glutathione, catalase, and superoxide dismutase, while reducing reactive oxygen species activity and the levels of triglycerides and malondialdehyde. Additionally, curcumin attenuated the development of hyperlipidemia in vivo. Mechanistically, 100 mg/kg of curcumin promoted O-GlcNAcylation and increased the expression of O-linked N-acetylglucosamine transferase in HaCaT cells. Furthermore, apolipoprotein C3 was identified as a substrate of O-linked N-acetylglucosamine transferase, and O-GlcNAcylation of apolipoprotein C3 enhanced its stability. Rescue experiments further verified that curcumin exerts its effects by regulating apolipoprotein C3 expression. In conclusion, these findings provide novel insights into the treatment of hyperlipidemia.

This study assesses the association of metabolic drugs (specifically hypoglycemic and hypolipemic agents) with cardiovascular diseases (CVD) among the Lebanese population and patients' subgroups.

A nationwide cross-sectional retrospective study was carried out in Lebanon. The survey collected information on sociodemographic characteristics, lifestyles, comorbidities, and medication use. Logistic regression models were employed to analyze the data and determine associations between CVD and metabolic drugs. Stratification analyses were performed based on diabetes and dyslipidemia status.

The study found significant associations with CVD among the 2048 participants. Higher scores on the Lebanese Mediterranean Diet Score (LMDS; ORa = 1.06), hypertension (ORa = 1.71), diabetes (ORa = 1.75), dyslipidemia (ORa = 1.89), family history of CVD (ORa = 1.58), and smoking (previous: ORa = 1.63, current: ORa = 2.15) were linked to increased CVD odds. Higher income (intermediate: ORa = 0.64, high: ORa = 0.40) was inversely related to it. A subsequent model that included hypoglycemic and lipid-lowering medications yielded similar results. However, neither hypoglycemic nor lipid-lowering medications demonstrated a significant association with CVD risk. A third regression model was conducted by taking the classes of drugs as an independent variable. Also, the result revealed that all the classes of medication were not associated with the risk of CVD. Stratification by diabetes revealed LMDS and hypertension as risk factors in both groups. Among non-diabetic participants, dyslipidemia (ORa = 2.40), current smoking (ORa = 2.28), and higher income (intermediate: ORa = 0.57, high: ORa = 0.62) were linked to CVD. Among people with diabetes, a family history of CVD (ORa = 2.69) increased the CVD odds, while being an employer (ORa = 0.49) lowered it. Stratification by dyslipidemia showed consistent risk factors, and higher LMDS (ORa = 1.07), diabetes (ORa = 2.14), hypertension (ORa = 1.79), and previous smoking (ORa = 1.95) were linked to CVD without dyslipidemia. Being a female (ORa = 0.52) and having a lower income (ORa = 0.40) were associated with lower CVD odds in those with dyslipidemia. Subgroup analyses showed that medications were not significantly associated with CVD odds among patients with diabetes or hyperlipidemia.

This study's findings highlight the importance of addressing modifiable risk factors and socioeconomic factors to reduce the burden of CVD. Targeted interventions and longitudinal research are necessary to optimize preventive strategies and improve the management of CVD in individuals using hypoglycemic and hypolipemic agents in low- and medium-income countries.

Although the importance and benefit of heme oxygenase-1 (HO-1) in diabetes rodent models has been known, the contribution of HO-1 in the pre-diabetic patients with hyperlipidemia risk still remains unclear. This cross-sectional study aims to evaluate whether HO-1 is associated with hyperlipidemia in pre-diabetes.

Serum level of HO-1 was detected using commercially available ELISA kit among 1,425 participants aged 49.3-63.9 with pre-diabetes in a multicenter Risk Evaluation of cAncers in Chinese diabeTic Individuals: A lONgitudinal (REACTION) prospective observational study. Levels of total cholesterol (TC) and triglyceride (TG) were measured and used to defined hyperlipidemia. The association between HO-1 and hyperlipidemia was explored in different subgroups.

The level of HO-1 in pre-diabetic patients with hyperlipidemia (181.72 ± 309.57 pg/ml) was obviously lower than that in pre-diabetic patients without hyperlipidemia (322.95 ± 456.37 pg/ml). High level of HO-1 [(210.18,1,746.18) pg/ml] was negatively associated with hyperlipidemia (OR, 0.60; 95% CI, 0.37-0.97; p = 0.0367) after we adjusted potential confounding factors. In subgroup analysis, high level of HO-1 was negatively associated with hyperlipidemia in overweight pre-diabetic patients (OR, 0.50; 95% CI, 0.3-0.9; p = 0.034), especially in overweight women (OR, 0.42; 95% CI, 0.21-0.84; p = 0.014).

In conclusion, elevated HO-1 level was negatively associated with risk of hyperlipidemia in overweight pre-diabetic patients, especially in female ones. Our findings provide information on the exploratory study of the mechanism of HO-1 in hyperlipidemia, while also suggesting that its mechanism may be influenced by body weight and gender.

Post-hospitalized acute coronary syndrome (ACS) patients in Indonesia National Insurance does not pay for the use of high-intensity statin (HIS) for secondary prevention after ACS hospitalization. Moreover, a cost-utility analysis needs to be conducted to evaluate the cost-effectiveness of prescribing HIS and low-to-moderate-intensity statin (LMIS) per quality-adjusted life year (QALY). This study aimed to estimate the cost-utility of long-term HIS treatment in post-hospitalized ACS patients in Indonesia compared to current practice.

This study compared the economic outcomes of long-term HIS and LMIS in Indonesian post-hospitalized ACS patients. A lifetime Markov model predicted ACS-related events, costs, and QALY from a payer perspective. A systematic review estimated treatment-specific event probabilities, post-event survival, health-related quality of life, and Indonesia medical-care expenses from published sources. This study conducted probabilistic sensitivity analysis (PSA) using 1000 independent Monte Carlo simulations and a series of one-way deterministic sensitivity analyses utilizing a tornado diagram. The economic evaluation model proved that intensive HIS treatment can increase per-patient QALYs and care expenditures compared to LMIS. The use of HIS among post-hospitalized ACS patients had ICER 31.843.492 IDR per QALY gained, below the Indonesia willingness-to-pay (WTP) for terminal disease and life-saving treatment.

From the Indonesia payer perspective, using HIS for post-hospitalized ACS patients in Indonesia is cost-effective at 31.843.492 IDR per QALY gained.

This guideline is the first Iranian guideline developed for the diagnosis, management, and treatment of hyperlipidemia in adults. The members of the guideline developing group (GDG) selected 9 relevant clinical questions and provided recommendations or suggestions to answer them based on the latest scientific evidence. Recommendations include the low-density lipoprotein cholesterol (LDL-C) threshold for starting drug treatment in adults lacking comorbidities was determined to be over 190 mg/dL and the triglyceride (TG) threshold had to be >500 mg/dl. In addition to perform fasting lipid profile tests at the beginning and continuation of treatment, while it was suggested to perform cardiovascular diseases (CVDs) risk assessment using valid Iranian models. Some recommendations were also provided on lifestyle modification as the first therapeutic intervention. Statins were recommended as the first line of drug treatment to reduce LDL-C, and if its level was high despite the maximum allowed or maximum tolerated drug treatment, combined treatment with ezetimibe, proprotein convertase subtilisin/kexin type 9 inhibitors, or bile acid sequestrants was suggested. In adults with hypertriglyceridemia, pharmacotherapy with statin or fibrate was recommended. The target of drug therapy in adults with increased LDL-C without comorbidities and risk factors was considered an LDL-C level of <130 mg/dl, and in adults with increased TG without comorbidities and risk factors, TG levels of <200 mg/dl. In this guideline, specific recommendations and suggestions were provided for the subgroups of the general population, such as those with CVD, stroke, diabetes, chronic kidney disease, elderly, and women.

This systematic review aimed to gather data on the effects of sumac supplementation on lipid profile. A systematic literature search was carried out using electronic databases (PubMed, Scopus, and Web of Science) up to March 2023 to identify eligible randomized controlled trials (RCTs) assessing the effects of sumac intake on lipid profile as an outcome. All participants enrolled in our study were adult individuals who consumed sumac, in various forms, as an intervention. The included articles were assessed using the Cochrane risk of bias assessment tool. Heterogeneity tests of the selected trials were performed using the I2 statistic. Random effects models were assessed based on the heterogeneity tests, and pooled data were determined as the weighted mean difference with a 95% confidence interval. In total, seven RCTs with a total sample size of 570 subjects were included. This study found a significant decrease in total cholesterol (TC) (weighted mean difference [WMD]: -10.01 mg/dL; 95% CI: -18.67, -1.34), triglyceride (TG) (WMD: -8.52 mg/dL; 95% CI: -14.79, -2.25), and low-density lipoprotein (LDL)-C levels (WMD: -9.25 mg/dL; 95% CI: -14.56, -3.93); Moreover, a significant increase was observed in high-density lipoprotein (HDL)-C concentration (WMD: 2.97 mg/dL; 95% CI: 0.75, 5.19). The reduction in TG and TC was greater in studies with a duration of ≥12 compared to <12 weeks. The increase in HDL-C was greater in participants with an intervention duration of ≥12 compared to <12 weeks. Moreover, subgroup analysis based on the dose of sumac suggested a significant reduction in TC and LDL, specifically for doses below 3 g. Consumption of sumac significantly decreased serum TC, LDL-C, and TG concentrations. This study suggested significantly positive effects on HDL-C by intake of sumac. Longer interventions (>12 weeks) have a more favorable impact on TC, LDL-C, and HDL-C, while sumac doses below 3 g/day show greater effects on TC and LDL-C. These findings underscore the potential of sumac supplementation as a valuable approach to lipid profile management.

Hyperlipidemia (HLP) is a metabolic disorder caused by abnormal lipid metabolism. Recently, the prevalence of HLP caused by poor dietary habits in the population has been increasing year by year. In addition, lipid-lowering drugs currently in clinical use have shown significant improvement in blood lipid levels, but are accompanied by certain side effects. However, bioactive marine substances have been shown to possess a variety of physiological activities such as hypoglycemic, antioxidant, antithrombotic and effects on blood pressure. Therefore, the hypolipidemic efficacy of marine bioactive substances with complex and diverse structures has also attracted attention. This paper focuses on the therapeutic role of marine-derived polysaccharides, unsaturated fatty acids, and bioactive peptides in HLP, and briefly discusses the main mechanisms by which these substances exert their hypolipidemic activity in vivo.
