Summary

Nonalcoholic steatohepatitis (NASH) is a liver condition often linked to obesity and diabetes. While its progression is uncertain, NASH can lead to cirrhosis, with liver transplantation as a last resort.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Internal Medicine

Context:

  • Nonalcoholic steatohepatitis (NASH) is a progressive liver disease characterized by fat accumulation, inflammation, and liver cell damage.
  • Often asymptomatic, NASH is frequently diagnosed incidentally through elevated liver enzymes and hepatomegaly.
  • Associated conditions include obesity, diabetes mellitus, hypercholesterolemia, and hypertriglyceridemia.

Purpose:

  • To define Nonalcoholic steatohepatitis (NASH), its clinical presentation, associated risk factors, and current understanding of its pathogenesis.
  • To outline the natural history and potential complications of NASH, including progression to cirrhosis.
  • To discuss current treatment strategies, emphasizing lifestyle modifications and experimental pharmacologic agents, and the role of liver transplantation.

Summary:

  • NASH involves macrovesicular steatosis and lobular hepatitis, mimicking alcoholic hepatitis but without alcohol abuse.
  • Key clinical signs include hepatomegaly and elevated serum aminotransferases; other liver function tests are typically normal.
  • Pathogenesis is linked to lipid peroxidation and oxidative stress; while often stable, NASH can progress to cirrhosis.

Impact:

  • Highlights the need for further research into NASH pathogenesis and natural history.
  • Underscores the importance of managing associated metabolic conditions to potentially slow disease progression.
  • Informs clinical practice regarding diagnosis, management, and treatment options for NASH patients, including end-stage liver disease.
