What is the risk of Hepatitis C Virus (HCV) in Non-Alcoholic Steatohepatitis (NASH) and liver disease complicated by fatty liver?

From the Guidelines

The risk of Hepatitis C Virus (HCV) in Non-Alcoholic Steatohepatitis (NASH) and liver disease complicated by fatty liver is significant, and patients with both conditions face a higher risk of developing advanced fibrosis, cirrhosis, and hepatocellular carcinoma.

Key Considerations

• The presence of HCV and NASH can accelerate liver damage by increasing oxidative stress, insulin resistance, and promoting a pro-inflammatory state in the liver, creating a synergistic effect that accelerates fibrosis development 1.
• For patients with HCV and fatty liver, the primary recommendation is to treat the HCV infection with direct-acting antivirals (DAAs) such as sofosbuvir/velpatasvir (Epclusa) for 12 weeks, glecaprevir/pibrentasvir (Mavyret) for 8-12 weeks, or sofosbuvir/ledipasvir (Harvoni) for 8-12 weeks, depending on viral genotype and prior treatment history.
• After achieving HCV clearance, focus should shift to managing the underlying fatty liver disease through lifestyle modifications including weight loss of 7-10% of body weight, Mediterranean diet, and regular exercise (150 minutes of moderate activity weekly) 1.
• For NASH with significant fibrosis, medications like pioglitazone (15-30mg daily) or vitamin E (800 IU daily) may be considered in non-diabetic patients.
• Regular monitoring with liver function tests every 3-6 months and periodic imaging or elastography to assess fibrosis progression is essential.

Management and Prevention

• Smoking cessation is recommended for NAFLD patients, as smoking is associated with liver fibrosis and is known to be a risk factor for the development of HCC 1.
• Patients with liver cirrhosis associated with NAFLD should abstain from alcohol because drinking it increases the risk of HCC and liver-related mortality.
• Metformin may decrease the incidence of HCC, but the use of sulfonylurea and insulin may increase the incidence of HCC.
• Statin use may reduce the risk of developing HCC by 37%, but results in patients with NAFLD remain insufficient.

From the Research

Risk of Hepatitis C Virus (HCV) in Non-Alcoholic Steatohepatitis (NASH) and Liver Disease

The provided studies do not directly address the risk of Hepatitis C Virus (HCV) in Non-Alcoholic Steatohepatitis (NASH) and liver disease complicated by fatty liver.

Available Information on NASH and Liver Disease

• NASH is a subtype of nonalcoholic fatty liver disease and a progressive and chronic liver disorder with a significant risk for the development of liver-related morbidity and mortality 2.
• The treatment of NASH is focused on lifestyle modifications, including weight loss through diet and exercise, and management of associated comorbidities such as diabetes, hypertension, and cardiovascular diseases 3, 4.
• There is no currently approved pharmacotherapy for NASH, but medications targeting metabolic disease risk factors and some antifibrotic medications are used for NASH patients 2.
• Nonalcoholic fatty liver disease (NAFLD) is the most common form of liver disease in the United States, affecting up to 30% of adults, and individuals with obesity are at highest risk of NAFLD 5.

Limitations of Available Evidence

• The provided studies do not discuss the risk of HCV in NASH and liver disease complicated by fatty liver.
• The studies focus on the management and treatment of NASH, as well as the risk factors and symptoms associated with the disease.
