CSF Monoamine Metabolite and Beta Endorphin Levels in Recently Detoxified Alcoholics and Healthy Controls: Prediction of Alcohol Cue‐Induced Craving?

Abnormalities in central neurotransmitter systems have been described in alcohol-dependent individuals and may contribute to alcohol craving. This study compared cerebrospinal fluid (CSF) levels of monoamine metabolites and beta endorphin levels in samples from early-onset alcohol-dependent patients (n = 20), late-onset alcohol-dependent patients (n = 14), and healthy controls (n = 23). It also evaluated whether these CSF measures levels predicted the degree of craving experienced in response to an alcohol cue. Individuals meeting DSM-III and -IV R-criteria for alcohol dependence, 1 to 3 months postdetoxification, and healthy controls underwent a lumbar puncture. Patients also completed a cue exposure test day between 3 and 15 days later. Alcohol-dependent patients had lower CSF levels of the norepinephrine metabolite MHPG compared with the healthy subjects, but this difference disappeared when differences in age between the groups were accounted for. No other group comparisons between patients and healthy subjects reached significance. CSF levels of the dopamine metabolite HVA were significantly higher in the early-onset patients compared with the late-onset patients and controls. The CSF measures did not predict the precue levels of craving, or the increase in craving after alcohol cue exposure. These results are inconclusive about the role of monoaminergic dysregulation in recovering alcoholics. They also question the utility of these CSF measures to predict alcohol cue reactivity in patients who have been sober at least 1 month.

Alcohol cue reactivity and private self-consciousness among male alcoholics

Recent alcohol cue exposure studies have noted that not all alcoholics demonstrate increased reactivity when presented with alcohol-related cues. This study examined the relationship of private self-consciousness (PSC) to subjective, self-report measures of reactivity and measures of negative mood states that involve a focus on internal processes. These subjective measures of reactivity were contrasted with salivary reactivity, an objective measure of reactivity which does not require individual self-report or awareness. A cue reactivity assessment was administered to 47 men meeting DSM-III-R criteria for a diagnosis of alcohol dependence. Our hypothesis, that PSC would predict urge reactivity status and greater levels of negative mood states, was supported. Urge reactors were more likely to be high in PSC, while the proportions of salivary reactors and nonreactors were not significantly different between the high and low PSC groups. Although regression analyses indicated that PSC did not significantly predict urge to drink alcohol, it did predict angry/frustrated mood and sad/depressed mood at the first alcohol trial. These results suggest that individuals high in PSC may benefit more from cue exposure-based treatment, as they are more likely to be urge reactors and to evidence negative mood reactivity. Low PSC individuals may be at higher risk for relapse given they are less able to recognize internal reactions signaling the presence of a high-risk alcohol use situation, and therefore less likely to mobilize coping responses.

The effects of cue exposure on reaction time in male alcoholics.

The present study investigates reaction time (RT) as a measure of attentional deficits produced during alcohol cue exposure. Twenty-four male alcoholic patients responded to a series of computer-generated tones as rapidly as possible during baseline and again during either an alcohol cue exposure period or exposure to a control beverage (water). Patients required increased time to respond to the tones when exposed to alcohol cues. No such increase in RT was found during exposure to a control beverage. In addition, RT was significantly correlated with self-reported urge to drink. These data provide initial validation for the use of RT as an objective measure of cue reactivity. Both theoretical and clinical implications for the use of RT as a measure of the effects of cue exposure are discussed.

Alcohol cue exposure directed at a goal of moderate drinking

A novel form of moderation-oriented cue exposure treatment for alcohol dependence is illustrated in a single case study. Formal clinic-based cue exposure following a priming dose of the client's preferred beverage is succeeded by supervised and then unsupervised in vivo practice at resisting continued drinking in tempting situations. Improvements on a range of outcome measures seen up to 12-month follow-up were supported by the results of an analogue measure of desire to drink. The potential place of this form of treatment in the range of services offered to problem drinkers is discussed.

Alcohol cue reactivity: effects of detoxification and extended exposure.

Alcoholics' reactions to drinking-related stimuli (cue reactivity) have been well documented and alcohol cue exposure treatment has been conducted recently in several clinical trials. Prior to conducting large-scale clinical trials it is important to know what effects detoxification may have on cue reactivity. However, no information is available about the effects of stage of detoxification or of detoxification medication on alcohol cue reactivity. In this study, 45 male alcoholics, detoxified without medication, were assessed during either their second, fourth or sixth day of withdrawal. Further, their reactivity was compared to that of alcoholics detoxified with chlordiazepoxide (n = 15), and to that of alcoholics in their fourth week after drinking (n = 28). Cue reactivity assessment investigated salivation and urge to drink after 3 minutes of water cue exposure and then after 3 minutes of alcohol cue exposure. Urges to drink were assessed during an additional 15 minutes of alcohol exposure to explore latency to maximum reactivity and habituation. Reactivity did not differ as a function of group membership, although salivation was elevated to both beverages during the first week of detoxification. Of the sample, 70% reacted to alcohol with increased urge and 65% with increased salivation, with no difference between groups in proportions of reactors. The maximum urge to drink occurred in the first 6 minutes of alcohol exposure, followed by a gradual and significant decrease. There were no differences on these measures between alcoholics in their first or fourth week after their last drink. Implications for theory and clinical applications are discussed.
