Patients who had significant alcohol intake or positive markers of other liver diseases or who were taking drugs known to produce fatty liver were excluded. The clinical, biochemical and histological profile of this group was studied. RESULTS： Fifty-one patients with NAFLD formed the study population. Their median age and BMI were 34（17-58） years and 26.7（21.3-32.5） kg/m^2 respectively and 46 （90.1%） were males. The majority of the patients had mild inflammation, either grade 1 [32 （63%）] or grade 2 [16 （31%）] and only 3 （6%） patients had severe （grade 3） inflammation. Twenty-three （45%）, 19 （37%）, 8（16%） and 1（2%） patient had stage 0, 1, 2 and 3 fibrosis respectively on index biopsy and none had cirrhosis. On univariate analysis, triglyceride levels more than 150 mg % （OR = 7.1; 95% CI： 1.6-31.5, P = 0.002） and AST ALT ratio 〉 1 （OR = 14.3; 95% CI： 1.4-678.5, P = 0.008） were associated with high grades of inflammation and none was associated with advanced fibrosis. On multivariate logistic regression analysis, hypertriglyceridemia 〉150 mg% was the only factor independently associated with presence of high grade of inflammation （OR = 1.6; 95% CI： 1.3-22.7, P =0.02）, while none was associated with advanced fibrosis. Triglyceride levels correlated positively with inflammatory grade （r = 0.412; P = 0.003）. CONCLUSION： NAFLD in North Indian patients is a disease of young over-weight males, most of whom are insulin resistant and they tend to have a mild histological disease at presentation.展开更多
