This study examined the association between non-invasive liver fibrosis biomarkers and non-alcoholic fatty liver disease (NAFLD) in an apparently healthy population. A matched case-control design was used to analyze 145 pairs of participants with and without NAFLD. Six liver fibrosis indexes were evaluated: Aspartate Aminotransferase to Alanine Aminotransferase Ratio (AAR), Aspartate Aminotransferase to Platelet Ratio Index (APRI), fibrosis index based on four factors (FIB-4), modified FIB-4 (mFIB-4), Forns Index, and Gamma-Glutamyl Transpeptidase to Platelet Ratio (GPR). Adjusted logistic regression analyses showed significant associations between mFIB-4 and Forns Index with NAFLD, highlighting their potential as tools for early detection. These markers demonstrated consistency across multiple analyses, supporting their potential use for screening asymptomatic individuals, especially in resource-limited settings. However, traditional markers like APRI and GPR showed limited utility in this cohort, emphasizing the need for contextual biomarker selection. Future studies should validate these findings across diverse populations and investigate their diagnostic capabilities in prospective cohort studies to improve early NAFLD detection and intervention.

Objective: The objective was to explore the potential existence and nature of the relationship between serum of uric acid (SUA) and serum uric acid to serum creatinine ratio (SUA/SCr) with reduced estimated glomerular filtration rate (eGFR) in patients with non-alcoholic fatty liver disease (NAFLD). Methods: A cross-sectional study was conducted among apparently healthy subjects with NAFLD (n=485). The association between tertiles of SUA and SUA/SCr with reduced eGFR (n=56) were investigated after adjustments for potentially relevant confounders. Also, the diagnostic performances of SUA and SUA/SCr were evaluated with the receiver operating characteristic (ROC) curve analysis. Results: In the adjusted models, SUA showed a significant positive association with reduced eGFR in the highest tertile (OR 5.65, 95% CI 2.48-12.86, p<0.001), and SUA/SCr, in the lowest tertile (4.21, 95% CI 1.76-10.07, p=0.001). The ROC curve analysis did not reveal any significant difference between the corresponding values of area under the curve for SUA and SUA/SCr (0.70 and 0.67, respectively; p=0.521). Conclusions: We revealed significant and independent associations of elevated SUA and reduced SUA/SCr with kidney function decline in NAFLD. However, the clinical utility of these two biomarkers seemed to be limited for the mentioned purpose and needs further investigations.
