Bazick and colleagues (2015) investigated predictors of advanced fibrosis or NASH in 100 US patients with type 2 diabetes, reporting white race, body mass index, waist circumference, and certain metabolic biomarkers (e.g., alanine aminotransferase, aspartate aminotransferase, hemoglobin A1c) to be predictive of NASH.[16] Age, Hispanic ethnicity, body mass index, waist-to-hip ratio, hypertension, and other biomarkers (e.g., alanine aminotransferase-to-aspartate aminotransferase ratio) were predictive of advanced fibrosis. This evidence concerns the gene GPT and metabolic dysfunction-associated steatohepatitis.
