Abstract:
Alcohol use contributes to the progression of liver disease in HIV-HCV co-infected persons, but alcohol interventions have never addressed low levels of alcohol use in this population. We enrolled 110 persons consuming at least 4 alcoholic drinks weekly in a clinical trial comparing two active 18-month long interventions, delivered every 3 months by phone, brief advice about drinking versus a motivational intervention. Final assessment was at 24 months. MI had larger reductions in alcohol use days than the BA arm at all follow-up assessments. The treatment by time effect was not significant for days of drinking (p = 0.470), mean drinks per day (p = 0.155), or for the continuous FIB-4 index (p = 0.175). Drinking declined in both conditions from baseline, but given the small sample, we do not have sufficient data to make any conclusion that one treatment is superior to the other.Trial Registry Trial registered at clinicaltrials.gov; Clinical Trial NCT02316184.
