Non-alcoholic fatty liver disease (NAFLD) has been proposed as the hepatic manifestation of the metabolic syndrom (Ms), with insulin resistance (IR) as the common pathophysiological mechanism. Methods: we included 145 patients with NAFLD proven liver biopsy. NAS-score was employed to grading NAFLD. We determined anthropometric measurements, basal blood pression (BP), biochemical measurements including high lipoprotein cholesterol (HDL-Chol), low-density lipoprotein cholesterol (LDL-Chol), triglycerides and leptin levels, homeostasis model assessment index (HOMA.IR), and abdominal ultrasound scan (US) was performed. Diagnosis of Ms was performed based on ATP III criteria. Results: average age was 43.6 + 11.2 years old and the mean body mass index (BMI) was 39 } 10.7 kg/m². Sex distribution was: females 66 and males 79. Forty patients (27.5%) presented a NAS score > = 5. Waist circumference (p = 0.007), systolic and diastolic BP (p = 0.002 and p = 0.003 respectively), (HOMA-IR) (p>0.0001), body mass index BMI (p = 0.04), Ms (p = 0.04) and US-NAFLD were significantly associated with NAS-score > = 5. Independent factors associated to NAS-score > = 5 were Ms and BMI > 30. Leptin levels were higher in patients with advanced fibrosis (. F2) compared to patients with mild fibrosis (F0-F1) (75.5 + 50.2 ng/ml vs - 39.7 + 38.4 ng/ml respectively; p = 0.002). Conclusion: presence of Ms and obesity (BMI >30) are the principal independent factors associated to NASH (NAS score > = 5). Leptin levels and BMI are higher in patients with advanced fibrosis.
