Abstract: BACKGROUND: The eradication of the Hepatitis C Virus (HCV) reduce the risk of liver cancer (LC), but lifestyle changes after cure may counterbalance its benefit. Our study investigates lifestyle changes that occur in HCV patients with Sustained Virological Response (SVR) after direct-acting antiviral (DAA) treatment. METHODS: In this prospective, single-center study, HCV patients with advanced liver disease (F3/F4) treated and cured with DAA were invited to fill a lifestyle habits questionnaire in and perform abdominal ultrasound (US), blood extraction and anthropometric measurements within the 1st month after SVR and every 6 months thereafter until 48 months of follow-up, LC development, death, or loss to follow-up. RESULTS: , 74.2% were overweight or obese and 6.6% had an US with hepatic steatosis. Within a year of SVR, 9% of males and 4% of females progressed from normal weight to overweight/obesity and 19.4% increased alcohol consumption. At 48 months, there were statistically significant increases in BMI (0.75, p = 0.001) and alcohol consumption (6.4% p = 0.007). CONCLUSIONS: In this prospective cohort, successful HCV therapy was followed by significant changes in lifestyle habits translating into increases in BMI and alcohol consumption. These post-SVR changes raise concerns that the chemopreventive benefits of HCV cure may be counterbalanced by increased risks of liver disease progression and LC development from metabolic risk factors and alcohol use. Post-SVR, patients may benefit from intensive counseling and pharmacotherapy to address obesity and alcohol use. TRIAL REGISTRATION/ CLINICAL TRIAL NUMBER: Not applicable.
