Nonalcoholic fatty liver disease (NAFLD) progresses from simple steatosis to nonalcoholic steatohepatitis (NASH), cirrhosis, and liver cancer. Understanding NASH pathogenesis and treatment is crucial due to rising obesity and diabetes rates.
Area of Science:
- Hepatology
- Metabolic Syndrome
- Gastroenterology
Context:
- Nonalcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver conditions, including steatosis, nonalcoholic steatohepatitis (NASH), cirrhosis, and hepatocellular carcinoma.
- NASH is an aggressive form of NAFLD, increasingly studied due to the prevalence of risk factors like obesity, type II diabetes mellitus, and dyslipidemia, particularly in Korea.
- The multifactorial pathogenesis of NASH involves insulin resistance, fatty acid accumulation, oxidant stress, mitochondrial dysfunction, and cytokine dysregulation.
Purpose:
- To review the current understanding of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH).
- To highlight the key factors contributing to NASH pathogenesis and progression.
- To discuss current therapeutic strategies and unresolved issues in NAFLD/NASH management.
Summary:
- NASH pathogenesis is complex, involving metabolic and inflammatory pathways, with genetic and environmental factors influencing progression.
- Lifestyle modifications are the primary treatment for NAFLD, though insulin-sensitizing drugs show potential for NASH.
- While promising, the efficacy of antioxidants and lipid-lowering agents in NASH requires further investigation.
Impact:
- Improved understanding of NASH pathogenesis can lead to targeted therapies.
- Addressing risk factors like obesity and diabetes is critical for NAFLD prevention and management.
- Further research is needed to resolve uncertainties regarding NASH natural history, pathogenesis, and treatment efficacy.

Diseases of the Liver and Gallbladder
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
