Since triglyceride (TG)-rich very low-density lipoprotein (VLDL) is a precursor of sdLDL and is overproduced by MASLD, the composition of VLDL may be more directly associated with MAFLD than sdLDL-C or plasma TG.

Liver steatosis and visceral fat area (VFA) were evaluated using CT. VLDL-C was calculated as the total C minus direct LDL-C minus HDL-C. The average VLDL-TG level can be estimated using VLDL-C×5, according to the principle of the Friedewald equation for LDL-C. Thus, VLDL-TG was estimated as VLDL-C×5, and Excess TG was calculated as plasma TG minus VLDL-C×5.</p><p><strong>Results: </strong>Patients with MASLD were younger, more likely to be men and drinkers, and had higher VFA, TG, sdLDL-C, and excess TG, while VLDL-C was comparable.

The odds ratios for MASLD were 2.4-, 3.7-, and 3.9-fold higher for Excess TG ranges of 0-24, 25-49, and ≥ 50 mg/dL, respectively, relative to ＜0 mg, and a close relationship remained significant after adjustment for lipid- and adiposity-related parameters.</p><p><strong>Conclusions: </strong>Excess TG in VLDL was strongly associated with MASLD beyond TG and sdLDL-C levels, which may reflect the presence of TG-rich VLDL.</p>","PeriodicalId":15128,"journal":{"name":"Journal of atherosclerosis and thrombosis","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142132851","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epidemiological studies initially suggested an association between HDL-C levels and cardiovascular disease (CVD) risk; however, such a simple association has not been indicated by recent studies. Notably, genome-wide studies have highlighted discrepancies between HDL-C levels and CVD outcomes, urging a deeper exploration of the role of HDL. The key to this shift lies in elucidating the role of HDL in reverse cholesterol transport (RCT), which is a fundamental anti-atherosclerotic mechanism. Understanding RCT has led to the identification of therapeutic targets and novel interventions for atherosclerosis. However, clinical trials have underscored the limitations of HDL-C as a therapeutic target, prompting the re-evaluation of the role of HDL in disease prevention. Further investigations have revealed the involvement of HDL composition in various diseases other than CVD, including chronic kidney disease, Alzheimer's disease, and autoimmune diseases. The anti-inflammatory, antioxidative, and anti-infectious properties of HDL have emerged as crucial aspects of its protective function, opening new avenues for novel biomarkers and therapeutic targets. Omics technologies have provided insights into the diverse composition of HDL, revealing disease-specific alterations in the HDL proteome and lipidome. In addition, combining cell-based and cell-free assays has facilitated the evaluation of the HDL functionality across diverse populations, offering the potential for personalized medicine.
