Overview

NAFLD/NASH was first described in a 1980 series of obese, non-alcoholic patients of the Mayo Clinic.[1] Since that seminal description, our understanding of NAFLD has progressed minimally. [2]

Historical Perspective

  • First introduced in 1980, NAFLD is a quite new concept. [3]
  • It is divided into non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH) primarily based on histologic findings.
  • Biopsies of NAFL may also display macrovesicular steatosis with lobular and periportal irritation however do now not display cellular injury and fibrosis (steatohepatitis), which characterizes NASH. [4]
  • NAFL has in large part been taken into consideration benign, but recent cohort studies display a high hazard for development to NASH in as much as 44% on serial biopsies at 5 years.
  • NASH reasons modern fibrosis which could result in cirrhosis and hepatocellular cancer (HCC).
