BACKGROUND: Nonalcoholic steatohepatitis (NASH) has often been described in obese women with diabetes and/or hyperlipidemia. We evaluated the clinical, biochemical and histological profile of NASH. METHODS: 52 patients with persistently elevated ALT (>40 IU/L) for >6 months with no history of significant alcohol consumption and negative serological work-up for hepatitis B and C and HIV were enrolled. Twenty-five patients were diagnosed as having NASH and their clinical, biochemical, and histological profile was evaluated. RESULTS: Of the 25 patients with NASH (mean age 33 years), 24 were men. Three were obese, seven had hyperlipidemia and two had impaired glucose tolerance. Thirteen patients presented with pain in the right hypochondrium, three with fatigue and weakness, and nine were asymptomatic. No patient had evidence of portal hypertension or liver cell failure. Mild elevation of ALT was the most common biochemical abnormality. Twenty-three of the 25 patients had ALT/AST ratio >1.0. Liver histology revealed macrovesicular steatosis in all, with mild inflammatory activity in the majority (70%). Fibrosis was seen in 12 patients-portal fibrosis in six, periportal fibrosis in three and bridging fibrosis in another three patients. None of the patients had features of cirrhosis. None of the factors was found to be associated with fibrosis except serum AST level, which was significantly higher in patients with fibrosis as compared to those without (89 [52] vs. 54 [18] IU/L; p<0.05). CONCLUSIONS: NASH is often seen in men, in the absence of obesity, diabetes and hyperlipidemia, and its severity is better assessed by liver histology than clinical assessment.
