In reply: Duggan and Duggan are correct to highlight the well recognised role of alcohol consumption in progression of hepatitis C virus (HCV) infection. Alcohol consumption has been found to increase viral load and accelerate hepatic fibrosis in HCV infection.1,2
While studies have reported that a history of alcohol consumption adversely affects treatment outcomes (with some reporting a dose–response relationship),3,4 treatment success has also been reported among patients who continue to consume moderate amounts of alcohol during treatment.5 Although there are biologically plausible mechanisms through which alcohol consumption might negatively affect treatment, low rates of treatment success among drinkers may also be related to lack of adherence to treatment regimen in this population.1 To date, no study has specifically measured the effect of alcohol consumption during treatment while adequately controlling for the effects of compliance, disease progression and baseline viral load.
Until studies are undertaken that measure the direct effect of alcohol consumption on treatment success, while adjusting for compliance, it seems reasonable to advise patients to decrease their level of alcohol consumption before and during HCV treatment. However, given that some patients have successfully completed treatment without abstaining from alcohol consumption, this should not be an automatic exclusion criterion.
