Medication adherence star ratings measures, health care resource utilization, and cost.

OBJECTIVE: To examine the association between missed CMS Star Ratings quality measures for medication adherence over 3 years for diabetes, hypertension, and hyperlipidemia medications (9 measures) and health care utilization and relative costs. STUDY DESIGN: Retrospective cohort study. METHODS: The study examined eligible patients who qualified for the diabetes, statin, and renin-angiotensin system antagonist medication adherence measures in 2018, 2019, and 2020 and were continuously enrolled in a Medicare Advantage prescription drug plan from 2017 through 2021. A total of 103,900 patients were divided into 4 groups based on the number of adherence measures missed (3 medication classes over 3 years): (1) missed 0 measures, (2) missed 1 measure, (3) missed 2 or 3 measures, and (4) missed 4 or more measures. To achieve a quality measure, patients had to meet the Pharmacy Quality Alliance 80% threshold of proportion of days covered during the calendar year. RESULTS: The mean age of the cohort was 71.1 years, and 49.9% were female. Compared with patients who missed 0 of 9 adherence measures, those who missed 1 measure, 2 or 3 measures, and 4 or more measures experienced 12% to 26%, 22% to 42%, and 24% to 50% increased risks, respectively, of all-cause and diabetes-related inpatient stays and all-cause and diabetes-related emergency department visits (all  P  values < .01). Additionally, patients who missed 1, 2 or 3, and 4 or more adherence measures experienced 14%, 19%, and 20% higher monthly medical costs, respectively. CONCLUSIONS: Missing Star Ratings quality measures for medication adherence was associated with an increased likelihood of health care resource utilization and increased costs for patients taking medications to treat diabetes, hypertension, and hyperlipidemia.

Discovery of Oral AMP-Activated Protein Kinase Activators for Treating Hyperlipidemia.

Activation of AMP-activated protein kinase (AMPK) is proposed to alleviate hyperlipidemia. With cordycepin and N6-(2-hydroxyethyl) adenosine (HEA) as lead compounds, a series of adenosine-based derivatives were designed, synthesized, and evaluated on activation of AMPK. Finally, compound V1 was identified as a potent AMPK activator with the lipid-lowering effect. Molecular docking and circular dichroism indicated that V1 exerted its activity by binding to the γ subunit of AMPK. V1 markedly decreased the serum low-density lipoprotein cholesterol levels in C57BL/6 mice, golden hamsters, and rhesus monkeys. V1 was selected as the clinical compound and concluded Phase 1 clinical trials. A single dose of V1 (2000 mg) increased AMPK activation in human erythrocytes after 5 and 12 h of treatment. RNA sequencing data suggested that V1 downregulated expression of genes involved in regulation of apoptotic process, lipid metabolism, endoplasmic reticulum stress, and inflammatory response in liver by activating AMPK.

Probiotics combined with atorvastatin administration in the treatment of hyperlipidemia: A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Hyperlipidemia is a common feature of chronic diseases. The aim of this work was designed to assess the role of probiotics (Lactobacillus casei Zhang, Bifidobactetium animalis subsp. lactis V9, and Lactobacillus plantarum P-8) in the treatment of hyperlipidemia. METHODS: Thirty three patients with hyperlipidemia were randomly divided into a probiotic group (n = 18) and a control group (n = 15). The probiotic group was administered probiotics (2 g once daily) and atorvastatin 20 mg (once daily), and the control group was administered a placebo (2 g once daily) and atorvastatin 20 mg (once daily). Serum and fecal samples were gathered for subsequent analyses. RESULTS: Time had a significant effect on the total cholesterol (TC), triglycerides (TG), and low-density lipoprotein-cholesterol (LDL-C) levels in the probiotic and control groups (P < .05). The gut microbial abundance in the probiotic group was markedly higher than that in the control group following 3-month probiotic treatment (P < .05). At the phylum level, probiotics exerted no notable effects on the relative abundance of Firmicutes, Bacteroidetes, and Actinobacteria but elevated that of Tenericutes and reduced Proteobacteria. At the genus level, probiotics increased the relative abundance of Bifidobacterium, Lactobacillus, and Akkermansia, and decreased that of Escherichia, Eggerthella, and Sutterella relative to the control group in months 1, 2, and 3 (P < .05). CONCLUSIONS: Probiotics optimize the gut microbiota structure and decrease the amount of harmful bacteria in patients with hyperlipidemia. Probiotics can influence the composition of gut microorganisms and increase their diversity and abundance in vivo. It is recommended to use probiotics combined with atorvastatin to treat patients with hyperlipidemia.

Synchronizing positive effect of vitamin C and chromium on hyper lipidemia, hyperglycemia, liver enzymes and BMI of diabetes mellitus type 2 patients.

This study investigates the combined effect of vitamin C and chromium on BMI, lipid profile, LFTs and HbA1c of Diabetes Mellitus type 2 patients. This is randomized controlled trial study. For this study a total of 60 patients (n=28 female, n=32 male) Diabetes Mellitus type 2 patients were selected. They were divided into treatment group (vitamin C (500mg) Chromium (200µg) and control group (placebo) comprising thirty patients per group. Mean age in control group and treatment group is 33± 5.729 and 33±7.017 respectively. Statistical analysis showed significant results of lipid profile; total cholesterol (mg/dl) 198±66.1 P=0.008, High-Density Lipoprotein 38±7.5, P<0.001, Low Density Lipoprotein (LDL) (mg/dl) 105.1±22.4, P=0.002 and Triglycerides 191±64.3, P=0.02 are respectively. Levels of serum ALT (u/l) (34.7±9.1, P<0.001) and AST (u/l) (31.6 ±8.6, P<0.001) were significantly lower as compared to control group. HbA1c percentages were also normalized (5.45±0.2, P<.001) as compared to group 2. BMI values were also improved (P=0.01) after treatment. Combined supplementation of vitamin C and chromium reduce the plasma lipid percentage, blood glucose levels and also improve the ALT and AST functions.

Mechanism of the components compatibility of Scutellariae Radix and Coptidis Rhizoma on mice with hyperlipidemia by regulating the Cyp4a family.

ETHNOPHARMACOLOGICAL RELEVANCE: Scutellaria baicalensis Georgi (Scutellariae Radix, SR) and Coptis chinensis Franch (Coptidis Rhizoma, CR) is a classic herbal pair used in many Traditional Chinese Medicine formulations in the treatment of hyperlipidemia (HLP). As effective ingredients of the drug pair, the effects and mechanisms of berberine and baicalin in the treatment of HLP in the form of components compatibility are still unclear. AIM OF THE STUDY: To explore the mechanism of the components compatibility of SR and CR in the treatment of HLP. MATERIALS AND METHODS: The HLP model was established by a high-fat diet. Serum biochemical indexes were detected. Transcriptomics and metabolomics were detected. RT-PCR and Western Blot were used to analyze the effect of RA on the expression of the Cyp4a family during the treatment of HLP. RESULTS: Berberine-baicalin (RA) has a good effect in the treatment of HLP. RA can significantly reduce the body weight and liver weight of HLP, reduce the levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL-C), and increase the level of high-density lipoprotein (HDL-C). Through transcriptomic analysis, RA significantly reversed the gene expression of Cyp4a10, Cyp4a12 b, Cyp4a31, and Cyp4a32 in cytochrome P450 family 4 subfamily a (Cyp4a) which related to fatty acid degradation in the liver of HLP mice. The results of fatty acid detection showed that RA could significantly regulate heptanoic acid, EPA, adrenic acid, DH-γ-linolenic acid, and DPA in the cecum of HLP mice. The Cyp4a family genes regulated by RA are closely related to a variety of fatty acids regulated by RA. RT-PCR confirmed that RA could regulate Cyp4a mRNA expression in HLP mice. WB also showed that RA can regulate the protein expression level of Cyp4a. CONCLUSION: The components compatibility of SR and CR can effectively improve the blood lipid level of HLP mice, its mechanism may be related to regulating Cyp4a gene expression and affecting fatty acid degradation, regulating the level of fatty acid metabolism in the body.

Screening of the effective sites of Cichorium glandulosum against hyperuricemia combined with hyperlipidemia and its network pharmacology analysis.

Cichorium glandulosum, a common traditional Chinese medicine used by Uyghur and Mongolian ethnic groups, is recognized for its potential to ameliorate metabolic disorders. However, the specific efficacy and mechanisms of Cichorium glandulosum in treating the comorbidity of hyperuricaemia and hyperlipidaemia remain unexplored. This study aims to explore the pharmacological effects and mechanisms of Cichorium glandulosum on this comorbidity through a combination of animal experiments, network pharmacology, and molecular docking techniques. A rat model of hyperuricaemia combined with hyperlipidaemia was established through a high-fat and high-purine diet, and the effective parts of the aqueous extract of Cichorium glandulosum to reduce uric acid and lipid levels were screened and the components of the parts were analysed by LC-MS/MS. The active components, core targets, and key pathways were analysed using network pharmacology and validated by molecular docking. Animal experimental results indicated that the n-butanol extract of Cichorium glandulosum showed a significant therapeutic effect on this comorbidity. Analysis of the n-butanol extract yielded 35 active ingredients and 138 intersecting targets related to diseases. Key targets identified through compound-target-pathway (C-T-P) and Protein-Protein Interaction (PPI) analyses included RELA, CASP3, PTGS2, TNF, and ESR1. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses revealed 2515 functional items and 164 pathways, respectively. Molecular docking demonstrated that isochlorogenic acid A, baicalin, chicoric acid, and lactucopicrin showed the highest binding affinity to RELA and PTGS2. The n-butanol fraction from the aqueous extract of Cichorium glandulosum was found to reduce uric acid and lipid levels effectively. In summary, Cichorium glandulosum has a therapeutic effect on hyperuricaemia combined with hyperlipidaemia through its multi-component, multi-target, and multi-pathway characteristics.

Lipid-Lowering Medications are Associated with Reduced Sarcopenia-Related Quality of Life in Older Adults with Hyperlipidemia.

PURPOSE: Statins medications negatively affect age-associated loss of muscle mass and strength, termed sarcopenia, and neuromuscular junction (NMJ) integrity. However, their association with the sarcopenia-related-quality-of-life (SarQoL) is unknown. METHODS: In this cross-sectional, case control study, we recruited male nonusers (n = 75 and age 75.2 ± 5.9 years) and users (n = 77 and age 77.1 ± 6.2 years) of statins to evaluate SarQoL and handgrip strength (HGS). We also measured plasma C-terminal agrin fragment-22 (CAF22) as a marker of NMJ degradation. RESULTS: Statin users had higher CAF22, and lower HGS, and cumulative SarQoL scores than non-users (all p < 0.05). Plasma CAF22 exhibited negative correlations with SarQoL scores for physical and mental health, locomotion, functionality, activities-of-daily-living, and cumulative SarQoL in statins users and non-users (all p < 0.05). Lastly, the cumulative SarQoL scores exhibited positive associations with HGS and gait speed in the study participants (all p < 0.05). CONCLUSIONS: Collectively, statin usage was associated with NMJ degradation and reduced SarQoL. Statins should be cautiously prescribed in patients with sarcopenia with reduced QoL.

Pragmatic Trial of Messaging to Providers About Treatment of Hyperlipidemia (PROMPT-LIPID): A Randomized Clinical Trial.

BACKGROUND: Lipid-lowering therapy (LLT) is underutilized for very high-risk atherosclerotic cardiovascular disease. PROMPT-LIPID (PRagmatic Trial of Messaging to Providers about Treatment of HyperLIPIDemia) sought to determine whether electronic health record (EHR) alerts improve 90-day LLT intensification in patients with very high-risk atherosclerotic cardiovascular disease. METHODS: PROMPT-LIPID was a pragmatic trial in which cardiovascular and internal medicine clinicians within Yale New Haven Health (New Haven, CT) were cluster-randomized to receive an EHR alert with individualized LLT recommendations or no alert for outpatients with very high-risk atherosclerotic cardiovascular disease and LDL-C (low-density lipoprotein cholesterol), ≥70 mg/dL. The primary outcome was 90-day LLT intensification (change to high-intensity statin and addition of ezetimibe or PCSK9i [proprotein subtilisin/kexin type 9 inhibitors]). Secondary outcomes included LDL-C level, proportion of patients with LDL-C of <70 or < 55 mg/dL, rate of major adverse cardiovascular events, ED visit incidence, and 6-month mortality. Results were analyzed using logistic and linear regression clustered at the provider level. RESULTS: The no-alert group included 47 clinicians and 1370 patients (median age, 71 years; 50.1% female, median LDL-C, 93 mg/dL); the alert group included 49 clinicians and 1130 patients (median age, 72 years; 47% female, median LDL-C 91, mg/dL). The primary outcome was observed in 14.1% of patients in the alert group as compared with 10.4% in the no-alert group. There were no differences in any secondary outcomes at 6 months. Among 542 patients whose clinicians (n=46) did not dismiss the EHR alert recommendations, LLT intensification was significantly greater (21.2% versus 10.4%, odds ratio, 2.33 [95% CI, 1.48-3.66]). CONCLUSIONS: With a real-time, targeted, individualized EHR alert as compared with usual care, the proportion of patients with atherosclerotic cardiovascular disease with LLT intensification was numerically higher but not statistically significant. Among clinicians who did not dismiss the alert, there was a > 2-fold increase in LLT intensification. EHR alerts, coupled with strategies to reduce clinician dismissal, may help address persistent gaps in LDL-C management.

Punicic acid ameliorates obesity-related hyperlipidemia and fatty liver in mice via regulation of intestinal flora and lipopolysaccharide-related signaling pathways.

Punicic acid (PA), mainly found in pomegranate seed oil (PSO), has attracted increasing attention due to its potential to mitigate obesity. The regulation of intestinal microflora was identified as a crucial factor and an effective strategy to reverse obesity-related hyperlipidemia and non-alcoholic fatty liver disease (NAFLD). To assess the impact of PSO on hyperlipidemia related to obesity, we investigated the hepatic lipid status and gut microbiota regulation in mice over 13 weeks of feeding a high-fructose high-fat diet (HFHFD). Serum lipid markers, including TG, TC and LDL-C, were markedly reduced in hyperlipidemic mice. PSO supplementation reduced hepatic lipid accumulation and steatosis, inhibited the expression of pro-inflammatory mediators (including IL-6 and IL-1ß), and restored the normal levels of the anti-inflammatory cytokine IL-10. In addition, PSO also alleviated oxidative stress and increased T-AOC and SOD activities, as well as GSH levels, while reducing the MDA content in the liver of HFHFD-fed mice. The activation of TLR4/MyD88/NF-κB and TLR4/IL-22/STAT3 signaling pathways in the liver due to the HFHFD was also evidently inhibited by PSO. Furthermore, supplementation of PSO ameliorated the HFHFD-induced dysbiosis of intestinal microflora, resulting in a markedly increased proportion of Muribaculaceae, a decreased ratio of Blautia, and elevated levels of microbiota-derived short-chain fatty acids (SCFAs). Moreover, the expression of tight junction proteins correlated with intestinal barrier function was notably restored in the colon. The collected results indicate that PSO may be an effective nutraceutical ingredient for attenuating lipid metabolic disorders.

Rhizoma Alismatis Decoction improved mitochondrial dysfunction to alleviate SASP by enhancing autophagy flux and apoptosis in hyperlipidemia acute pancreatitis.

BACKGROUND: Acute pancreatitis (AP) is an inflammatory disorder of the exocrine pancreas, especially hyperlipidemia acute pancreatitis (HLAP) is the third leading cause of acute pancreatitis which is more severe with a greater incidence of persistent multiorgan failure. HLAP inflicts injury upon the organelles within the acinar cell, particularly mitochondria, the endolysosomal-autophagy system, and is accompanied by senescence-associated secretory phenotype (SASP). RAD, only two consists of Rhizoma Alismatis and Atractylodes macrocephala Rhizoma, which is best known for its ability to anti-inflammatory and lipid-lowering. Nevertheless, the mechanism by which RAD alleviates HLAP remains obscure, necessitating further investigation. PURPOSE: The study aimed to assess the effects of the RAD on HLAP and to elucidate the underlying mechanism in vivo and in vitro, offering a potential medicine for clinical treatment for HLAP. STUDY DESIGN AND METHODS: C57BL/6 mice with hyperlipidemia acute pancreatitis were induced by HFD and CER, then administrated with RAD. AR42J were stimulated by cerulein or conditioned medium and then cultured with RAD. Serums were analyzed to evaluate potential pancreas and liver damage. Furthermore, tissue samples were obtained for histological, and protein investigations by H&E, Oil red staining, and Western blot. In addition, western blot and immunofluorescent staining were utilized to estimate the effect of RAD on mitochondrial function, autophagy flux, and SASP. RESULTS: In vivo, RAD considerably alleviated systemic inflammation while attenuating TC, TG, AMY, LPS, inflammatory cytokines, histopathology changes, oxidative damage, mitochondrial fission, and autophagy markers in HLAP mice. Impaired autophagy flux and mitochondrial dysfunction resulted in a significant enhancement of NLRP3 and IL-1ß in the pancreas. RAD could reverse these changes. In vitro, RAD significantly restored mitochondrial membrane potential and oxidative phosphorylation levels. RAD decreased Beclin-1 and LC3-II expression and increased LAMP-1 and Parkin-Pink expression, which showed that RAD significantly ameliorated HLAP-induced damage to the mitochondria function by suppressing mitochondrial oxidative damage and enhancing autophagy flux and mitophagy to remove the damaged mitochondria. In addition, we found that RAD could up-regulate the expression of BAX, and Bad and down-regulate the expression of p16, and p21, indicating that RAD could promote damaged cell apoptosis and alleviate SASP. CONCLUSIONS: This study revealed that RAD ameliorates mitochondrial function to alleviate SASP through enhancing autophagy flux, mitophagy, and apoptosis which provided a molecular basis for the advancement and development of protection strategies against HLAP.

[Research on mechanism of hypolipidemic effect of Massa Medicata Fermentata based on metabolomics].

This paper aims to study the therapeutic effect of Massa Medicata Fermentata on hyperlipidemia model rats and investigate its mechanism of hypolipidemic effect with the help of non-targeted metabolomics. The mixed hyperlipidemia model rats were constructed by giving high-fat chow. After successful modeling, the rats were divided into the model group, pravastatin sodium group(4.4 mg·kg~(-1)), lipotropic group(0.1 g·kg~(-1)), high-dose group(2.4 g·kg~(-1)), medium-dose group(1.2 g·kg~(-1)), and low-dose group(0.6 g·kg~(-1)) of Massa Medicata Fermentata, and they were administered for four weeks once daily. An equal volume of ultrapure water was given to the blank group and model group. Serum lipid level and liver hematoxylin-eosin(HE) staining were used as indicators to estimate the intervention effect of Massa Medicata Fermentata on mixed hyperlipidemia, and the changes in metabolites in plasma of mixed hyperlipidemia model rats were analyzed by non-targeted metabolomics. The mechanism of the hypolipidemic effect of Massa Medicata Fermentata was analyzed through metabolite pathway enrichment. The results showed that compared with the model group, the Massa Medicata Fermentata administration group, especially the high-dose group, could significantly reduce the content of total cholesterol(TC), triglyceride(TG), and low-density lipoprotein cholesterol(LDL-c)(P<0.05 or P<0.01), and liver HE staining revealed that the number of adipocytes in the high-dose group was reduced to some extent. The potential biomarkers obtained by non-targeted metabolomics screening included glycerol 3-phosphate, sphingomyelin, sphingosine 1-phosphate, and deoxyuridine, which were mainly involved in the sphingolipid metabolism process, glycerophospholipid metabolism process, glycerol ester metabolism pathway, and pyrimidine metabolism pathway, totaling four possible metabolic pathways related to lipid metabolism. This study provides a reference for an in-depth investigation of the hypolipidemic mechanism of Massa Medicata Fermentata, which is of great significance for further promoting the clinical application of Massa Medicata Fermentata and increasing the indications.

Microbial Fermentation Enhances the Effect of Black Tea on Hyperlipidemia by Mediating Bile Acid Metabolism and Remodeling Intestinal Microbes.

Black tea (BT), the most consumed tea worldwide, can alleviate hyperlipidemia which is a serious threat to human health. However, the quality of summer BT is poor. It was improved by microbial fermentation in a previous study, but whether it affects hypolipidemic activity is unknown. Therefore, we compared the hypolipidemic activity of BT and microbially fermented black tea (EFT). The results demonstrated that BT inhibited weight gain and improved lipid and total bile acid (TBA) levels, and microbial fermentation reinforced this activity. Mechanistically, both BT and EFT mediate bile acid circulation to relieve hyperlipidemia. In addition, BT and EFT improve dyslipidemia by modifying the gut microbiota. Specifically, the increase in Lactobacillus johnsonii by BT, and the increase in Mucispirillum and Colidextribacter by EFT may also be potential causes for alleviation of hyperlipidemia. In summary, we demonstrated that microbial fermentation strengthened the hypolipidemic activity of BT and increased the added value of BT.

Discovery of Highly Potent Solute Carrier 13 Member 5 (SLC13A5) Inhibitors for the Treatment of Hyperlipidemia.

In the face of escalating metabolic disease prevalence, largely driven by modern lifestyle factors, this study addresses the critical need for novel therapeutic approaches. We have identified the sodium-coupled citrate transporter (NaCT or SLC13A5) as a target for intervention. Utilizing rational drug design, we developed a new class of SLC13A5 inhibitors, anchored by the hydroxysuccinic acid scaffold, refining the structure of PF-06649298. Among these, LBA-3 emerged as a standout compound, exhibiting remarkable potency with an IC50 value of 67 nM, significantly improving upon PF-06649298. In vitro assays demonstrated LBA-3's efficacy in reducing triglyceride levels in OPA-induced HepG2 cells. Moreover, LBA-3 displayed superior pharmacokinetic properties and effectively lowered triglyceride and total cholesterol levels in diverse mouse models (PCN-stimulated and starvation-induced), without detectable toxicity. These findings not only spotlight LBA-3 as a promising candidate for hyperlipidemia treatment but also exemplify the potential of targeted molecular design in advancing metabolic disorder therapeutics.

Berberine attenuates inflammation and oxidative stress and modulates lymphocyte E-NTPDase in acute hyperlipidemia.

Hyperlipidemia is a common clinically encountered health condition worldwide that promotes the development and progression of cardiovascular diseases, including atherosclerosis. Berberine (BBR) is a natural product with acknowledged anti-inflammatory, antioxidant, and metabolic effects. This study evaluated the effect of BBR on lipid alterations, oxidative stress, and inflammatory response in rats with acute hyperlipidemia induced by poloxamer-407 (P-407). Rats were pretreated with BBR (25 and 50 mg/kg) for 14 days and acute hyperlipidemia was induced by a single dose of P-407 (500 mg/kg). BBR ameliorated hypercholesterolemia, hypertriglyceridemia, and plasma lipoproteins in P-407-adminsitered rats. Plasma lipoprotein lipase (LPL) activity was decreased, and hepatic 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase activity was enhanced in hyperlipidemic rats. The expression of low-density lipoprotein receptor (LDL-R) and ATP-binding cassette transporter 1 (ABCA1) was downregulated in hyperlipidemic rats. BBR enhanced LPL activity, upregulated LDL-R, and ABCA1, and suppressed HMG-CoA reductase in P-407-administered rats. Pretreatment with BBR ameliorated lipid peroxidation, nitric oxide (NO), pro-inflammatory mediators (interleukin [IL]-6, IL-1ß, tumor necrosis factor [TNF]-α, interferon-γ, IL-4 and IL-18) and enhanced antioxidants. In addition, BBR suppressed lymphocyte ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) and ecto-adenosine deaminase (E-ADA) as well as NO and TNF-α release by macrophages isolated from normal and hyperlipidemic rats. In silico investigations revealed the binding affinity of BBR toward LPL, HMG-CoA reductase, LDL-R, PSK9, ABCA1, and E-NTPDase. In conclusion, BBR effectively prevented acute hyperlipidemia and its associated inflammatory responses by modulating LPL, cholesterolgenesis, cytokine release, and lymphocyte E-NTPDase and E-ADA. Therefore, BBR is an effective and safe natural compound that might be employed as an adjuvant against hyperlipidemia and its associated inflammation.

Alisol B regulates AMPK/mTOR/SREBPs via directly targeting VDAC1 to alleviate hyperlipidemia.

BACKGROUND: The occurrence of hyperlipidemia is significantly influenced by lipid synthesis, which is regulated by sterol regulatory element binding proteins (SREBPs), thus the development of drugs that inhibit lipid synthesis has become a popular treatment strategy for hyperlipidemia. Alisol B (ALB), a triterpenoid compound extracted from Alisma, has been reported to ameliorate no-nalcoholic steatohepatitis (NASH) and slow obesity. However, the effect of ALB on hyperlipidemia and mechanism are unclear. PURPOSE: To examine the therapeutic impact of ALB on hyperlipidemia whether it inhibits SREBPs to reduce lipid synthesis. STUDY DESIGN: HepG2, HL7702 cells, and C57BL/6J mice were used to explore the effect of ALB on hyperlipidemia and the molecular mechanism in vivo and in vitro. METHODS: Hyperlipidemia models were established using western diet (WD)-fed mice in vivo and oleic acid (OA)-induced hepatocytes in vitro. Western blot, real-time PCR and other biological methods verified that ALB regulated AMPK/mTOR/SREBPs to inhibit lipid synthesis. Cellular thermal shift assay (CETSA), molecular dynamics (MD), and ultrafiltration-LC/MS analysis were used to evaluate the binding of ALB to voltage-dependent anion channel protein-1 (VDAC1). RESULTS: ALB decreased TC, TG, LDL-c, and increased HDL-c in blood, thereby ameliorating liver damage. Gene set enrichment analysis (GSEA) indicated that ALB inhibited the biosynthesis of cholesterol and fatty acids. Consistently, ALB inhibited the protein expression of n-SREBPs and downstream genes. Mechanistically, the impact of ALB on SREBPs was dependent on the regulation of AMPK/mTOR, thereby impeding the transportation of SREBPs from endoplasmic reticulum (ER) to golgi apparatus (GA). Further investigations indicated that the activation of AMPK by ALB was independent on classical upstream CAMKK2 and LKB1. Instead, ALB resulted in a decrease in ATP levels and an increase in the ratios of ADP/ATP and AMP/ATP. CETSA, MD, and ultrafiltration-LC/MS analysis indicated that ALB interacted with VDAC1. Molecular docking revealed that ALB directly bound to VDAC1 by forming hydrogen bonds at the amino acid sites S196 and H184 in the ATP-binding region. Importantly, the thermal stabilization of ALB on VDAC1 was compromised when VDAC1 was mutated at S196 and H184, suggesting that these amino acids played a crucial role in the interaction. CONCLUSION: Our findings reveal that VDAC1 serves as the target of ALB, leading to the inhibition of lipid synthesis, presents potential target and candidate drugs for hyperlipidemia.

Pharmacists as clinical care partners: How a pharmacist-led intervention is associated with improved medication adherence in older adults with common chronic conditions.

BACKGROUND: Hypertension, hyperlipidemia, and type 2 diabetes (T2D) are 3 of the most common chronic conditions, but related medication adherence rates are far below 80%. Consequences of poor adherence include high health care utilization/costs and increased mortality. There is accumulating evidence in support of the benefits of affording pharmacists the opportunity to practice at the full scope of their licensure by engaging in patients' clinical care. OBJECTIVE: To examine the impact of a large national pharmacy chain's pharmacist-led interventions to improve medication adherence among older adults with hypertension, hyperlipidemia, or T2D. A secondary objective was to estimate the potential cost savings associated with improved adherence. METHODS: Participants were Medicare patients aged 18 years or older who had 2 or more prescription fills in at least 1 of the 3 therapeutic classes. The primary outcome, optimal adherence, was defined as proportion of days covered (PDC) of 80% or higher. A difference-in-differences (DID) design with a generalized linear model analytical approach was applied to examine differences between intervention participants and controls. The study period spanned from 2020 to 2022. RESULTS: Intervention participants (n = 317,613, age 70.1 years, female sex 57.0%) had lower baseline optimal adherence than controls (n = 943,389, age 73.3, female sex 56.1%) for diabetes (76.9% vs 79.8%), hypertension (79.0% vs 83.0%), and cholesterol (78.6% vs 82.1%). The DID results showed that between 2020 and 2022, optimal adherence had significant absolute increases for intervention participants (diabetes: +4.0%, hypertension: +6.3%, cholesterol: +6.1%) vs controls who declined in adherence (diabetes: -1.6%, hypertension: -0.4%, cholesterol: -1.4%). All DID models were significant at P < 0.0001. Total cost of care was projected based on improvements in adherence. Based on PDC improvements for the test population, we estimate that the pharmacist consultations were associated with annual total health care cost savings of $10,329,284 ($109 per capita), $31,640,660 ($122 per capita), and $21,589,875 ($75 per capita) for test population patients with diabetes, hypertension, and hyperlipidemia, respectively. CONCLUSIONS: The study found that the pharmacist-led interventions were significantly associated with increased optimal adherence over 2 years. These findings demonstrate the potential of pharmacist-led interventions to improve medication adherence among older adults with chronic conditions. Strategies to expand pharmacist-provided care must be further examined.

Nephroprotective effects of silymarin and its fabricated nanoparticles against aluminum-induced oxidative stress, hyperlipidemia, and genotoxicity.

BACKGROUND: Aluminum (Al) is a ubiquitous element with proven nephrotoxicity. Silymarin (SM) is a mixture of polyphenolic components extracted from Silybum marianum and exhibited protective influences. However, SM bioactivity can be enhanced by its incorporation in chitosan (CS) through the use of nanotechnology. This work proposed to assess the protective influence of SM and its loaded chitosan nanoparticles (SM-CS-NPs) on aluminum chloride (AlCl3)-induced nephrotoxicity. METHODS: Six groups were created randomly from 42 male Wistar rats and each one contains 7 rats (n = 7). Group I, acted as a control and received water. Group II received SM (15 mg/kg/day) and group III administered with SM-CS-NPs (15 mg/kg/day). Group IV received AlCl3 (34 mg/kg) and groups V and VI were treated with SM and SM-CS-NPs with AlCl3 respectively for 30 days. RESULTS: AlCl3 administration significantly elevated TBARS, H2O2, and kidney function levels besides LDH activity. Whereas GSH, CAT, SOD, GPx, GST, and GR values were all substantially reduced along with protein content, and ALP activity. Additionally, significant alterations in lipid profile, hematological parameters, and renal architecture were observed. Moreover, TNF-α, TGF-ß, and MMP9 gene expression were upregulated in kidney tissues. The administration of SM or its nanoparticles followed by AlCl3 intoxication attenuated renal dysfunction replenished the antioxidant system, and downregulated TNF-α, TGF-ß, and MMP9 gene expression in renal tissues compared to the AlCl3 group. CONCLUSION: SM-CS-NPs have more pronounced appreciated protective effects than SM and have the proficiency to balance oxidant/antioxidant systems in addition to their anti-inflammatory effect against AlCl3 toxicity.

Aqueous extract of fermented Eucommia ulmoides leaves alleviates hyperlipidemia by maintaining gut homeostasis and modulating metabolism in high-fat diet fed rats.

BACKGROUND: As a traditional Chinese medicinal herb, the lipid-lowing biological potential of Eucommia ulmoides leaves (EL) has been demonstrated. After fermentation, the EL have been made into various products with lipid-lowering effects and antioxidant activity. However, the anti-hyperlipidemic mechanism of fermented Eucommia ulmoides leaves (FEL) is unclear now. PURPOSE: To evaluate the effects of FEL on hyperlipidemia and investigate the mechanism based on regulating gut homeostasis and host metabolism. METHODS: Hyperlipidemia animal model in Wistar rats was established after 8 weeks high-fat diet (HFD) fed. The administered doses of aqueous extract of FEL (FELE) were 128, 256 and 512 mg/kg/d, respectively. Serum biochemical parameters detection, histopathological sections analysis, 16S rDNA sequencing of gut microbiota and untargeted fecal metabolomics analysis, were performed to determine the therapeutic effects and predict related pathways of FELE on hyperlipidemia. The changes of proteins and genes elated to lipid were detected by Immunofluorescence (IF) and quantitative real-time polymerase chain reaction (qRT-PCR). RESULTS: 56 Components in FELE were identified by UPLC-MS, with organic acids, flavonoids and phenolic acids accounting for the majority. The intervention of FELE significantly reduced the body weight, lipid accumulation and the levels of total cholesterol (TC), triglycerides (TG), and low-density lipoprotein-cholesterol (LDL-C) in hyperlipidemia rats, while increased the level of High-density lipoprotein-cholesterol (HDL-C). Meanwhile, FELE improved the inflammatory makers and oxidative stress factors, which is tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT). These results demonstrated that FETE can effectively reduce blood lipids and alleviate inflammation and oxidative damage caused by hyperlipidemia. Mechanistically, FELE restore the homeostasis of gut microbiota by reducing the Firmicutes/Bacteroidetes ratio and increasing the abundance of probiotics, especially Lactobacillus, Rombousia, Bacteroides, Roseburia, Clostridia_UCG-014_Unclassified, while modulated metabolism through amino acid, bile acid and lipid-related metabolism pathways. In addition, the Pearson correlation analysis found that the upregulated bilirubin, threonine, dopamine and downregulated lipocholic acid, d-sphingosine were key metabolites after FELE intervention. IF and qRT-PCR analysis showed that FELE upregulated the expression of fatty acid oxidation proteins and genes (PPARα, CPT1A), bile acid synthesis and excretion proteins and genes (LXRα, CYP7A1, FXR), and downregulated the expression of adipogenic gene (SREBP-1c) by regulating gut microbiota to improve metabolism and exert a lipid-lowering effect. CONCLUSION: This work filled the lipid-lowering mechanism gap of FEL. FELE can improve HFD-induced hyperlipidemia by regulating the gut microbiota homeostasis and metabolism. Thus, FEL has the potential to develop into the novel raw material of lipid-lowering drugs.

Red Yeast Rice and Statin Therapy in Patients with Hypercholesterolemia and the Comorbidities: A Retrospective Cohort Study on Lipid-Lowering Effects and Cardiovascular Outcomes.

Red yeast rice (RYR) is known for its lipid-lowering effects in patients with hypercholesterolemia; however, its comparative efficacy with statins and risk reduction remains uncertain. This retrospective study analyzed data from 337,104 patients with hyperlipidemia in the Chang Gung Research Database cohort, spanning from January 2016 to December 2021. Exclusion criteria were applied to ensure data completeness and compliance, including an age limit of [Formula: see text] years, absence of RYR or statin treatment, and a treatment duration of [Formula: see text] days. Propensity score matching was employed to minimize bias based on baseline factors, with one patient matching with four patients in the comparison group. The study encompassed a total of 5,984 adult hyperlipidemic patients, with 1,197 in the RYR group and 4,787 in the statin group. The patients were also stratified into statin ([Formula: see text]) or combined use ([Formula: see text]) groups for further comparison. Following one year of treatment, both the RYR and statin groups exhibited reductions in total cholesterol and triglyceride levels. Most biochemical parameters showed no significant differences, except for elevated glutamic oxaloacetic transaminase levels in the RYR group ([Formula: see text]) and increased glycohemoglobin levels in the statin group at the three-month mark ([Formula: see text]). In patients with comorbid diabetes, hypertension, kidney, or liver diseases, RYR and statins demonstrated comparable risks for emergency room (ER) visits, stroke, and myocardial infarction (MI). However, the combination of RYR and statins was associated with reduced stroke-related hospitalizations in patients with diabetes, hypertension, and kidney disease, as well as decreased MI-related hospitalizations in patients with hypertension and kidney disease (all [Formula: see text]). In conclusion, both RYR and statins effectively lower blood lipid levels and mitigate related complications. Combining these therapies may lead to fewer ER visits, reduced stroke frequency, and fewer MI hospitalizations in hypertensive and kidney disease patients, and they decreased all-cause mortality in the kidney disease population. Further research on combined therapy is warranted.

Hypolipidemic effect and gut microbiota regulation of Gypenoside aglycones in rats fed a high-fat diet.

ETHNOPHARMACOLOGICAL RELEVANCE: Gynostemma pentaphyllum (Thunb.) Makino has traditional applications in Chinese medicine to treat lipid abnormalities. Gypenosides (GPs), the main bioactive components of Gynostemma pentaphyllum, have been reported to exert hypolipidemic effects through multiple mechanisms. The lipid-lowering effects of GPs may be attributed to the aglycone portion resulting from hydrolysis of GPs by the gut microbiota. However, to date, there have been no reports on whether gypenoside aglycones (Agl), the primary bioactive constituents, can ameliorate hyperlipidemia by modulating the gut microbiota. AIM OF THE STUDY: This study explored the potential therapeutic effects of gypenoside aglycone (Agl) in a rat model of high-fat diet (HFD)-induced hyperlipidemia. METHODS: A hyperlipidemic rat model was established by feeding rats with a high-fat diet. Agl was administered orally, and serum lipid levels were analyzed. Molecular techniques, including RT-polymerase chain reaction (PCR) and fecal microbiota sequencing, were used to investigate the effects of Agl on lipid metabolism and gut microbiota composition. RESULTS: Agl administration significantly reduced serum levels of total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) and mitigated hepatic damage induced by HFD. Molecular investigations have revealed the modulation of key lipid metabolism genes and proteins by Agl. Notably, Agl treatment enriched the gut microbiota with beneficial genera, including Lactobacillus, Akkermansia, and Blautia and promoted specific shifts in Lactobacillus murinus, Firmicutes bacterium CAG:424, and Allobaculum stercoricanis. CONCLUSION: This comprehensive study established Agl as a promising candidate for the treatment of hyperlipidemia. It also exhibits remarkable hypolipidemic and hepatoprotective properties. The modulation of lipid metabolism-related genes, along with the restoration of gut microbiota balance, provides mechanistic insights. Thus, Agl has great potential for clinical applications in hyperlipidemia management.
