简要总结
The purpose of this study is to evaluate the efficacy of naltrexone in combination with an SSRI to reduce alcohol consumption in alcoholic patients with comorbid PTSD and depression.
We hypothesize that the combination of naltrexone and SSRI will exhibit a greater decrease in alcohol consumption than that seen with treatment with SSRI alone, or with a combination of another class of antidepressant and naltrexone. We also hypothesize that SSRI will be effective in treating PTSD and depressive symptoms and naltrexone will be well tolerated.
详细描述
OBJECTIVE
Alcoholics with current comorbid mental disorders constitute the majority of alcoholics in clinical settings. Although there are two FDA approved medications for the treatment of alcoholism (naltrexone and disulfiram), there are no established pharmacotherapies for individuals with comorbid alcoholism and psychiatric illnesses. Studies suggest that the class of antidepressants known as serotonin selective reuptake inhibitors (SSRIs) is effective in reducing alcohol use in depressed individuals. In addition, a small open label study has shown that SSRIs have similar effects on individuals with comorbid PTSD and alcoholism. Preclinical studies have shown that the combination of a serotonergic agent and naltrexone was more effective than either medication alone in suppressing alcohol intake. To address this issue, we are conducting a 13 week randomized clinical trial evaluating the effects of paroxetine, desipramine and naltrexone in reducing alcohol use in alcohol dependent individuals who currently meet DSM-IV diagnosis for Depressive Disorder or PTSD. RESEARCH PLAN: One hundred and twenty subjects who are alcohol dependent patients with comorbid PTSD or Depressive Disorder will be recruited from the following West Haven VA sources: the Substance Abuse Treatment program, the PTSD clinic, the Women's clinic, clinical referrals and advertisement. These subjects will be randomized in a double-blind fashion to one of four cells. We will compare paroxetine versus desipramine and naltrexone versus placebo. The antidepressant will be started at a low dose and titrated upward on a fixed schedule. The target dose will be 40mg for paroxetine and 200mg for desipramine. Minimum dosage permitted for study retention will be 20mg for paroxetine and 150mg for desipramine. Pharmacological treatments will last 13 weeks. Psychosocial treatment will involve medication compliance therapy, using the Microelectric Event Monitoring (MEMS) bottle caps. The specific aim of the research is to compare the relative effectiveness of paroxetine versus desipramine and naltrexone versus placebo in reducing the quantity and frequency of alcohol consumption. METHODOLOGY: The primary outcome measures of major interest will include: frequency and quantity of alcohol consumption, self-reported craving, self-reported psychiatric and emotional distress, diagnostic assessment or psychiatric symptoms and side effects. These outcomes will be measured by the following: self-assessments, Timeline Followback, Hamilton Depression and anxiety scales, CAPS, ASI, Quality of Life, breathalyzer tests and monthly liver function tests.

结局指标
主要结局
Mean Self-report Weekly Craving Via Obsessive Compulsive Drinking Scale (OCDS)
时间窗: beginning of treatment (week 1), and end of treatment (13 weeks)
The OCDS is a 14-item (rated 0-4), self-administered questionnaire for characterizing and quantifying the obsessive and compulsive cognitive aspects of craving and heavy (alcoholic) drinking, such as drinking-related thought, urges to drink, and the ability to resist those thoughts and urges. A higher total score indicates higher craving and ranges from 0-48.
Clinician-Administered PTSD Scale (CAPS)
时间窗: beginning of treatment (week 1), and end of treatment (13 weeks)
The CAPS is the gold standard in PTSD assessment. The CAPS-5 is a 30-item structured interview that can be used to: Make current (past month) diagnosis of PTSD Make lifetime diagnosis of PTSD Assess PTSD symptoms over the past week Clinician-Administered PTSD Scale for DSM-5 (CAPS-5). A higher score is associated with higher severity of PTSD. The score is interpreted as follows: 0-19=Asymptomatic/few symptoms 20-39=Sub-threshold/mild PTSD 40-59=Threshold PTSD/moderate 60-79=Severe PTSD \>80=Extreme PTSD
Hamilton Depression Rating Scale (HAM-D)
时间窗: beginning of treatment (week 1), and end of treatment (13 weeks)
The HAM-D ranges from 0 (Normal) to \>23 (Very Severe Depression)
Mean Number of Side Effects
时间窗: 12 weeks
Differences in mean number of side effects reported for each group. Side effects and common adverse symptoms were evaluated by the research staff weekly, using a modified version of the ystematic Assessment for Treatment Emergent Events. The symptoms that are known to be associated with treatment with desipramine, paroxetine, and naltrexone were specifically screened or on a weekly basis. The symptoms were then clustered into the following categories: gastrointestinal, emotional, cold and flu symptoms, skin, sexual, neurological, and cardiac.
