Effects of Direct-acting Antiviral Agents on Cognitive Function, and Depression in Chronic Hepatitis C

Detailed Summary

Minimal hepatic encephalopathy (MHE) is an important clinical variant of hepatic encephalopathy (HE), which occurs in up to 60-70% of patients with cirrhosis. The condition comprises a cognitive impairment, observed in patients with cirrhosis who have no clinical evidence of overt hepatic encephalopathy (OHE). It is associated with an increased incidence of road traffic accidents, reduced quality of life and it affects the ability to perform tasks of daily living. Successful treatment of hepatitis C has been reported to be associated with 62-84% reduction in all-cause mortality (deaths), 68-79% reduction in risk of HCC and 90% reduction in risk of liver transplantation. In addition, studies have shown that viral eradication may improve cognition when given interferon based regimens for HCV. With the available of safe, efficacious, all oral regimens for HCV, we plan to prospectively analyse the change in mood, depression and cognitive function in response to DAA therapy, in relation to outcomes of treatment.
