Non alcoholic fatty liver disease (NAFLD) and its aggressive form, non alcoholic steatohepatitis (NASH), are increasingly recognized due to rising obesity and diabetes rates. Early detection and management are crucial, as NASH can progress to cirrhosis and liver cancer.

Area of Science:

  • Hepatology
  • Metabolic Diseases
  • Gastroenterology

Context:

  • Non alcoholic fatty liver disease (NAFLD) and non alcoholic steatohepatitis (NASH) prevalence is rising globally, linked to increased rates of obesity and diabetes.
  • NAFLD is now considered a hepatic manifestation of metabolic syndrome, sharing insulin resistance as a common factor with diabetes, hypertension, and hypertriglyceridemia.

Purpose:

  • To highlight the growing clinical significance of NAFLD and NASH.
  • To emphasize the diagnostic challenges, particularly differentiating simple NAFLD from NASH, which currently requires liver biopsy.
  • To underscore the importance of considering NAFLD in patients with abnormal liver enzymes, especially those who are obese or diabetic.

Summary:

  • NAFLD encompasses a spectrum of liver conditions, from simple steatosis to NASH with inflammation and fibrosis.

  • While simple NAFLD often has a benign prognosis, NASH carries a risk of progression to cirrhosis, hepatocellular carcinoma, and liver failure.
  • Histological features of NAFLD can mimic alcoholic hepatitis, but the clinical course is typically more indolent.

    • Impact:

    • Accurate diagnosis and risk stratification are essential for managing patients with NAFLD/NASH.
    • Current therapeutic strategies focus on lifestyle modifications like weight reduction, diet, and exercise, alongside managing associated metabolic conditions.
    • Future treatments may target insulin resistance, with ongoing research into pharmacologic interventions for NAFLD and NASH.
