RESUMO
BACKGROUND AND STUDY AIMS: Nonalcoholic fatty liver disease is the most prevalent chronic liver disease globally and is linked to augmented susceptibility to type 2 diabetes mellitus (DM), cardiovascular disease, and microvascular complications inherent to DM, such as nephropathy, neuropathy, and retinopathy. The fibrosis-4 (FIB-4) scoring system, a noninvasive tool, is useful for predicting the extent of liver fibrosis across diverse pathologies. This study aimed to assess the potential predictive role of FIB-4 scores in microvascular complications associated with diabetes. PATIENTS AND METHODS: The medical records of patients with type 2 DM admitted to our endocrinology clinic between February 2019 and December 2020 were retrospectively evaluated. Parameters including demographic attributes, fasting blood glucose, glycated hemoglobin, aspartate aminotransferase, alanine aminotransferase, thrombocyte levels, and microvascular complications were recorded. The FIB-4 score was computed, and patients were categorized based on these scores (<1.3 and ≥ 1.3). RESULTS: The analysis included 312 patients with a median age of 60 (50-68 years); 39.7 % were men. The median duration of diabetes was 10 years (5-20 years), and the median FIB-4 score was 0.93 (0.63-1.34). Neuropathy, nephropathy, and retinopathy were observed in 50.6 %, 31.4 %, and 34 % of the patients, respectively. Although the FIB-4 score did not differ significantly between patients with and without neuropathy or retinopathy, patients with nephropathy exhibited higher FIB-4 scores. Notably, patients with FIB-4 scores ≥ 1.3 demonstrated a significantly higher prevalence of nephropathy. Logistic regression analysis demonstrated that higher FIB-4 scores were significantly associated with an increased risk of nephropathy. CONCLUSION: The FIB-4 score is a cost-effective and straightforward tool with potential applicability in predicting nephropathy in individuals with type 2 DM.
