RESUMO
Non-alcoholic fatty liver disease (NAFLD) is a slowly progressive chronic disease, with a high prevalence among obese, dyslipidemic or diabetic people, commonly presented as an asymptomatic mild elevation of serum aminotransferases. We report a patient who experienced an acute form of non-alcoholic steatohepatitis, as the first manifestation of NAFLD, due to exacerbation of pre-existing metabolic disorders by an extremely unhealthy lifestyle. A 50-year old, obese, diabetic man presented with a one-week history of jaundice and malaise. Analysis revealed elevated liver enzymes, bilirubin, lipids, and glucose. Based on patient's history, physical examination, laboratory results, and imaging findings, acute non-alcoholic steatohepatitis was established as a diagnosis of exclusion. The patient was started on a low-calorie diet free of carbohydrates and fats, in combination with insulin. A dramatic improvement of clinical and laboratory parameters was observed. In the context of extreme metabolic dysregulation, induced by unhealthy diet, NAFLD may present as an acute steatohepatitis.
