简要总结
The purpose of this study is to examine potential stress and immune systems adaptations underlying craving and relapse vulnerability in alcohol dependent (AD) individuals and social drinkers (SDs) with and without high levels of depressive symptomatology (+dep / - dep). Using the investigators experimentally validated guided imagery procedure, the investigators propose to examine the response of brain stress and immune systems to personalized guided stressful imagery using subjective, physiological and neurobiological assessments in 60 healthy controls and 60 alcoholic dependent individuals with and without depressive symptomatology.

研究组 & 干预措施
Social Drinkers Depressive Symptoms
30 non-dependent light socially drinking (SD) smokers with depressive symptoms will be recruited to participate in two laboratory sessions (Stress and Neutral / Relaxing). This arm will be exposed to both the personal stress imagery and neutral imagery interventions.

干预措施: Neutral Imagery (Behavioral)
Alcohol Dependent, Non-Depressive
30 treatment-engaged 28-day abstinent, alcohol dependent (AD) smokers, without Depressive symptoms. All AD subjects will either be admitted to the Clinical Neuroscience Research Unit (CNRU) of the Connecticut Mental Health Center for five weeks of inpatient stay and study participation (inpatient), or they will be scheduled for a two night stay on the CNRU following 3 weeks of abstinence (outpatient). This arm will be exposed to both the personal stress imagery and neutral imagery interventions.

结局指标
主要结局
cytokine levels
时间窗: Day 1 and 2, (-25, -5, +5, +15, +30, +45)
At each of the six time-points (-25, -5, +5, +15, +30, +45), serum cytokine concentrations of IL-6, TNFa, TNFR1, IL-10, IL1-ra, IL-4, IL1beta, and IL-12 will be collected. Levels will be determined by enzyme-linked immuno-sorbent assays using the DuoSet ELISA Development Kit from R\&D systems (Minneapolis, MN, USA). Plasma Cortisol and ACTH levels will also be colected and assays will be measured using standard radioimmunoassay procedures.
次要结局
- Alcohol Relapse(14, 30 and 90 day follow-ups)
- Alcohol Craving(Day 14, Day 30 and Day 90)
- Anxiety and Negative Mood(Day 14, Day 30 and Day 90)
