METHODS: Thirty-four patients diagnosed with liver steatosis by ultrasonographic examination participated in the study. We compared all nonalcoholic fatty liver disease and NASH cases, according to aminotransferase level, aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio and presence of metabolic syndrome. RESULTS: Sixteen of 25 patients with high aminotransferase levels were diagnosed with NASH and nine with simple fatty liver according to liver histology. Among the nine patients with normal aminotransferase levels, seven had NASH and two had simple fatty liver. The patients; with normal and high liver enzyme levels had almost the same prevalence of NASH and metabolic syndrome. Liver histology did not reveal any difference according to aminotransferase levels and AST/ALT ratio. CONCLUSION: Aminotransferase levels and AST/ALT ratio do not seem to be reliable predictors for NASH. Despite numerous non-invasive biomarkers, all patients with fatty liver should undergo liver biopsy.eninfo:eu-repo/semantics/openAccessNon-alcoholic steatohepatitisLiver enzymesLiver histologyFatty liver-diseaseInsulin-resistanceMetabolic significanceComplicationsAssociationDefinitionPrevalenceSpectrumNonobeseAdultsGastroenterology & hepatologyAdultAlanine transaminaseAnthropometryAspartate aminotransferasesBiopsyFatty liverFemaleHumansLiverMaleMetabolic syndrome xMiddle agedRetrospective studiesArticle0002653856000122-s2.0-6765124105918631868151519370784Gastroenterology & hepatologyFatty Liver; Proton Density (Concentration); Keratin-18Alanine aminotransferaseAminotransferaseAspartate aminotransferaseAbdominal painAdultAlanine aminotransferase aspartate amino transferase ratioAminotransferase blood levelAnthropometric parametersArticleChemical parametersClinical articleClinical featureControlled studyDisease markerEchographyFatty liverFemaleHepatomegalyHistologyHumanHuman tissueLaboratory diagnosisLiver biopsyMaleMetabolic syndrome XNonalcoholic fatty liverNormal value
