摘要:
目的 阐明关键血脂异常在代谢相关脂肪性肝病(MAFLD)肝脂肪变性进展中的独立及协同作用。 方法 选取2022年1月—2024年12月于首都医科大学附属北京友谊医院接受健康体检的7 697例参与者,最终纳入2 177例MAFLD患者为研究对象。采用瞬时弹性成像技术量化肝脂肪变性程度(S1~S3级)。应用多变量有序Logistic回归分析血清甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)与肝脂肪变性严重程度的独立及协同关联,并检验其与代谢因素的交互作用及非线性关系。计量资料多组间比较采用单因素方差分析或Kruskal-Wallis H检验,计数资料多组间比较采用χ2检验。 结果 TG升高[比值比(OR)=1.77,95%置信区间(CI):1.48~2.10,P<0.001]与HDL-C水平降低(OR=1.35,95%CI:1.11~1.65,P=0.003)均与更严重的肝脂肪变性独立相关,且二者并存时关联最强(OR=2.40,95%CI:1.87~3.07,P<0.001)。剂量-反应关系分析提示,TG水平对肝脂肪变性存在非线性阈值效应,阈值为1.51 mmol/L(非线性P=0.001),低于此水平时肝脂肪变性程度随TG升高加剧更显著(P=0.001)。亚组分析提示,HDL-C降低与肝脂肪变性严重程度的关联仅限于男性、年轻成人(<45岁)及代谢更健康的亚组(包括非糖尿病、非肥胖、非高尿酸血症及非高血压者)。是否肥胖与异常的TG水平和HDL-C水平之间存在显著的交互作用(交互作用P值均<0.05)。LDL-C升高与肝脂肪变性的关联则局限于特定亚组人群(非肥胖、无高尿酸血症)。 结论 TG水平升高与HDL-C水平降低是与MAFLD肝脂肪变性严重程度相关的独立因素。脂质的协同效应及其与代谢因素的交互作用可进一步细化风险分层,为MAFLD的精准管理提供依据。 Abstract:Objective To clarify the independent and synergistic effects of dyslipidemia in the progression of hepatic steatosis in metabolic dysfunction-associated fatty liver disease (MAFLD). Methods A total of 7 697 participants who underwent physical examination in Beijing Friendship Hospital, Capital Medical University, from January 2022 to December 2024 were enrolled, and finally 2 177 patients with MAFLD were enrolled as subjects. Transient elastography was used to quantify the severity of hepatic steatosis (grades S1-S3). The multivariable ordinal Logistic regression analysis was used to investigate the independent and synergistic associations of serum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) with the severity of hepatic steatosis, and their interactions and potential nonlinear relationships with metabolic factors were also examined. One-way analysis of variance or Kruskal-Wallis H test was used for comparison of continuous data between groups, and chi-square test was used for comparison of categorical data between groups. Results An increase in TG (odds ratio [OR]=1.77, 95% confidence interval [CI]: 1.48 — 2.10, P<0.001) and a reduction in HDL-C (OR=1.35, 95%CI: 1.11 — 1.65, P=0.003) were independently associated with a greater severity of hepatic steatosis, with the strongest association when both abnormalities coexisted (OR=2.40, 95%CI: 1.87 — 3.07, P<0.001). The dose-response relationship analysis further revealed a nonlinear threshold effect of TG on hepatic steatosis at the threshold of 1.51 mmol/L (Pnonlinearity=0.001), below which the severity of steatosis increased more rapidly with the increase in TG concentration (P=0.001). The subgroup analysis showed that the association between the reduction in HDL-C and the severity of steatosis was observed only in males, young adults (aged <45 years), and metabolically healthier subgroups (without diabetes, obesity, hyperuricemia or hypertension). Significant interactions were observed between the presence or absence of obesity and the abnormal levels of TG and HDL‑C (both Pinteraction<0.05). The association of the increase in LDL-C with steatosis was confined to specific subgroups (without obesity or hyperuricemia). Conclusion The increase in TG and the reduction in HDL-C are independently associated with the severity of hepatic steatosis in MAFLD. The synergistic effect of blood lipids and their interactions with metabolic factors may further refine risk stratification, so as to provide a basis for precise management of MAFLD. -
