Incidental finding of non-alcoholic steatohepatitis-cirrhosis.

SUMMARY: A 72-year-old man with type 2 diabetes volunteered to participate in the control group of a clinical study. The study evaluated non-alcoholic fatty liver disease in patients with kidney disease. The patient was followed at a gastroenterology department due to Crohn's disease and post-operative bile acid malabsorption. The patient had no symptoms or biochemical findings suggesting liver disease. Surprisingly, a transient elastography (FibroScan®) suggested advanced fibrosis with a median of 16.1 kPa. A liver biopsy showed non-alcoholic steatohepatitis (NASH)-cirrhosis. The diagnosis was only made incidentally and highlights how NASH-cirrhosis may be overlooked due to the lack of symptoms.

LEARNING POINTS: Clinicians treating high-risk populations, including patients with type 2 diabetes and/or components of the metabolic syndrome, should be aware of the frequently occurring co-existence with non-alcoholic fatty liver disease (NAFLD) and especially non-alcoholic steatohepatitis (NASH). Liver enzymes may be in the normal range even in people with steatosis, NASH, or even cirrhosis. The diagnosis of NAFLD should include evaluation of hepatic fibrosis as this is the most important prognostic factor for liver-related complications and mortality. Guidelines about systematic screening for NAFLD in patients with type 2 diabetes are incongruent.
