Abstract
Exclusion criteria: Age less than 18 years, patients with medical history, clinical or laboratory evidence of any other liver diseases, such as alcoholic or viral hepatitis, autoimmune hepatitis and those with decompensated liver cirrhosis, patients with a history of drug usage in the last 2 months, past history of chronic kidney disease, cardiovascular disease and/or malignancy.
Results:
We found that: Among 100 NAFLD patients, obesity (BMI≥25 Kg/m2) was present in 50 (50%) patients, and 50 (50%) patients were lean (BMI < 25 Kg/m2). Majorities (67%) of the patients were females, and females were predominant in both lean and obese groups. Mean (±SD) age for obese was 44.96±5.264 years, and that of nonobese was 44.62±5.760 years and that was similar in both groups.
Non obese Patients had significantly smaller WC than those obese patients with p value of (< 0.001) with the same p value for BMI.
Serum levels of triglycerides were significant with p value of (<0.001).
The metabolic syndrome tended to be less common in lean NAFLD patients compared to obese NAFLD (66% vs. 92%), However, at least one criterion of metabolic syndrome was seen in majority (89%, 24/27) of lean NAFLD patients.
Relation between obesity groups according to patient’s Liver Fat Score and it show highly statistically significant differences between obesity groups with high increase in Liver Fat Score in obese group when it compares with non obese group with p value of (<0.009).
