简要总结
The purpose of the study is to find out if a medication,naltrexone is helpful for HIV-infected women who sometimes drink too much. The study will try to find out whether women like the medication, whether the medication helps them cut back on their drinking, and whether it helps improve their overall health. Naltrexone has not been used widely among people who are engaged in less severe drinking and in primary health care settings. Therefore, the investigators would like to determine whether it is helpful among women who sometimes drink 4 or more drinks per occasion or 7 or more drinks per week. The investigators hypothesize that by taking naltrexone, women with hazardous drinking pattern will reduce their drinking which in turn will improve their medication adherence, improve their health and quality of life.
详细描述
The primary objective of this study is to evaluate the acceptability and effectiveness of a treatment program for hazardous drinking, delivered within HIV-clinic outpatient settings, that involves oral naltrexone. The central hypothesis is that women randomized to the treatment program will have decreased rates of hazardous drinking and improved clinical and behavioral health outcomes that are associated with hazardous drinking. The investigators have formulated this hypotheses based on the existing literature, the preliminary data and the clinical experience. The investigators hypothesize that women randomized to receive an alcohol treatment intervention will be less likely to have hazardous drinking behavior 6-months after enrollment, compared to women who received similar assessments but no formal treatment intervention. The investigators hypothesize that 4-months after enrollment, women randomized to receive an alcohol treatment intervention will have improved adherence to HIV antiretroviral therapy, improved CD4 cell counts, reduced HIV viral load, and reduced risky sexual behavior, compared to women who receive similar assessments but no formal intervention.
The investigators will recruit 90 women from 3 different sites in Florida, Washington DC and Chicago. Of those 90 women 60 will receive naltrexone and 30 will receive placebo. Study participants will take the medication for 4 months but the investigators will follow them for 7 months. At baseline, 2 months, 4 months and 7 months, the investigators will administer study questionnaires and assess their liver enzymes, CD4 count and viral load. The investigators will also follow them up at month 1 and 3 to reinforce the medication intake and to assess for any possible side effects.
New treatment options are available, but their impact on hazardous drinking has not yet been evaluated among HIV-infected women, many of whom are poor, minorities, or who have associated mental health or substance abuse problems. Delivery of therapeutic interventions must be improved in order to reduce hazardous drinking in women with HIV/AIDS. The proposed research is significant because the therapy will be offered within HIV clinic settings and will potentially improve the health of a population that is significantly undertreated. In addition to determining the effectiveness of an alcohol treatment intervention, the investigators will also identify key barriers and facilitators associated with adherence to pharmacologic treatment for alcohol in women with hazardous drinking. The findings will directly impact the type and quality of care for hazardous drinking in this subset of HIV-infected individuals and will inform both primary and secondary prevention efforts
