FRIDAY, Sept. 29, 2023 (HealthDay News) — For patients with chronic hepatitis C virus (HCV) infection starting direct-acting antiviral (DAA) therapy, according to a study published online, Drinking alcohol is not associated with reduced odds of sustained virological response (SVR) September. 26 inches JAMA Network Open.
Emily J. Cartwright, MD, of the Veterans Affairs Medical Center in Atlanta, and colleagues evaluated whether alcohol consumption at the start of DAA treatment was associated with a reduced likelihood of SVR. The analysis included 69,229 patients with chronic HCV infection who initiated DAA therapy between January 1, 2014, and June 30, 2018.
Researchers found that 94.4% of patients achieved SVR. Overall, 46.6% of participants were abstinent without alcohol use disorder (AUD), 13.3% were abstinent with AUD, 19.4% were low-risk drinkers, and 4.5% were moderate-risk drinkers. Risky drinking, 16.2% had high-risk drinking or AUD. There were no differences in SVR across drinking categories, even among patients with high-risk drinking or AUD, after adjusting for other confounders (odds ratio, 0.95; 95% confidence interval, 0.85 to 1.07). Furthermore, there was no interaction between liver fibrosis stage as measured by Fibrosis 4 score.
“These findings suggest that limiting DAA treatment based on alcohol consumption creates unnecessary barriers for patients and challenges hepatitis C elimination goals,” the authors wrote.
