Hepatitis C (HCV) is the most common blood born virus in the United States, affecting 1.8% of the general population and more than 5% of veterans using VA facilities. As veterans with HCV have high rates of co-morbid alcohol use disorders that accelerate greatly the liver damage caused by HCV, a safe and effective treatment for alcohol use disorders is needed. Baclofen is a novel treatment for alcohol use disorders that has minimal effect on the liver and may represent a safe and efficacious treatment option for veterans with HCV and co-morbid alcohol use disorders.

Description Project: Efficacy of baclofen in reducing alcohol consumption in veterans with HCV Principal Investigator: Peter Hauser, MD Keywords: Hepatitis C, Substance-Related Disorders, Alcoholism Abstract PLAN/METHODS: Two sites of the national VA Hepatitis C Resource Center, including Minneapolis and Portland VAMCs, the Long Beach VAMC, and the San Diego VAMC (total 4 sites) will recruit 180 men, women, and minority veterans who are HCV positive and currently drinking alcohol. Participants will be assessed for current alcohol use and alcohol use disorders and enrolled in the study if they meet eligibility criteria, mainly that they are drinking more than 7 drinks a week or have one heavy drinking day a week for the preceding two weeks. Enrolled subjects will be randomly assigned to one of two groups: Experimental group (Baclofen) or control (placebo). Subjects will be followed for a total of 14 weeks, and follow-up data will be collected at a total of 11 visits (weeks 1,2,3,4,6,8,10,12, and 14). At each visit, interviews will be conducted by a blinded interviewer assessing current stage of change and current alcohol use along with any changes in mood and psychological or somatic symptoms. HCV viral titers will be obtained at baseline and again at week 12 to determine the effect of abstinence on this measure. Data will also be collected from participants' medical records regarding enrollment and attendance in substance abuse treatment or self-help programs (Alcoholics Anonymous). Data will be analyzed using repeated measure ANOVAs to compare the groups on alcohol use and stage of change. CLINICAL RELEVANCE: This study focuses on a current VHA priority: treatment of veterans with HCV. Alcohol use in this population is a major risk factor for progression of liver disease. We anticipate that the Baclofen proposed in this study will result in reduced alcohol use, which is expected to result in a slowing of the progression of liver disease, improvement in physical health, and a reduction in long-term service utilization and mortality rates. POTENTIAL IMPACT ON VETERANS HEALTH CARE: Effectively addressing alcohol use disorders in a hepatitis clinic will contribute to a new standard of care for HCV patients within the VA. Co-located care for patients with comorbid medical and substance use disorders is likely to improve access to effective treatment, acceptance by patients and improve clinical efficiency.
