  •   Objective  To investigate the association between noninvasive liver fibrosis markers and carotid plaque (CP) in patients with lean metabolic dysfunction-associated fatty liver disease (MAFLD), and to provide a basis for screening high-risk populations.  Methods  A total of 957 patients with lean MAFLD who underwent physical examination in Subei People’s Hospital from January 2021 to June 2023 was enrolled as the observation cohort, with the presence or absence of CP as the outcome, and fibrosis-4 (FIB-4) index and nonalcoholic fatty liver disease fibrosis score (NFS) were used to assess liver fibrosis degree. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The multivariate logistic regression analysis, the restricted cubic spline analysis, the receiver operating characteristic curve, and the mediation effect analysis were used to investigate the association between liver fibrosis degree and CP.  Results  The prevalence rate of CP was 36.6% in the lean MAFLD population. Compared with the non-CP group(n=607), the CP group (n=350) had a significantly higher proportion of male patients, a significantly higher proportion of patients with smoking/diabetes/hypertension, and significantly higher levels of age, creatinine, blood urea nitrogen, triglycerides, fasting blood glucose, aspartate aminotransferase, aspartate aminotransferase/alanine aminotransferase ratio, NFS, and FIB-4 index, as well as significantly lower levels of platelet count and albumin (all P<0.05). The multivariate logistic regression analysis showed that after adjustment for confounding factors, FIB-4 index (odds ratio[OR]=2.979, 95% confidence interval[CI]:2.141 — 4.219, P<0.001) and NFS (OR=1.747, 95%CI: 1.499 — 2.046, P<0.001) were positively correlated with CP. Both FIB-4 index and NFS had a good value in predicting CP. Hypertension had a significant indirect effect on the prevalence rate of CP through its impact on liver fibrosis markers, and its mediating effect accounted for 39.5% — 40.8% of the total effect (P<0.001).  Conclusion  In patients with lean MAFLD, NFS and FIB-4 index are significantly positively correlated with the prevalence rate of CP, and they can be used as potential epidemiological predictive indicators. Liver fibrosis markers may play a mediating role in the association between hypertension and CP. Interventions targeting hypertension and liver fibrosis markers may help to prevent and delay the progression of CP.
