Impact and Role of Hypothalamic Corticotropin Releasing Hormone Neurons in Withdrawal from Chronic Alcohol Consumption in Female and Male Mice. J Neurosci 2023; 43:7657-7667. [PMID: 37833068 PMCID: PMC10634552 DOI: 10.1523/jneurosci.1153-23.2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/24/2023] [Accepted: 09/29/2023] [Indexed: 10/15/2023] Open
Abstract
Worldwide, alcohol use and abuse are a leading risk of mortality, causing 5.3% of all deaths (World Health Organization, 2022). The endocrine stress system, initiated by the peripheral release of corticotropin releasing hormone (CRH) from primarily glutamatergic neurons in the paraventricular nucleus of the hypothalamus (PVN), is profoundly linked with alcohol use, abuse, and relapse (Blaine and Sinha, 2017). These PVN CRH-releasing (PVNCRH) neurons are essential for peripheral and central stress responses (Rasiah et al., 2023), but little is known about how alcohol affects these neurons. Here, we show that two-bottle choice alcohol consumption blunts the endocrine-mediated corticosterone response to stress during acute withdrawal in female mice. Conversely, using slice electrophysiology, we demonstrate that acute withdrawal engenders a hyperexcitable phenotype of PVNCRH neurons in females that is accompanied by increased glutamatergic transmission in both male and female mice. GABAergic synaptic transmission was unaffected by alcohol history. We then tested whether chemogenetic inhibition of PVNCRH neurons would restore stress response in female mice with a history of alcohol drinking in the looming disk test, which mimics an approaching predator threat. Accordingly, inhibition of PVNCRH neurons reduced active escape in hM4Di alcohol history mice only. This study indicates that stress-responsive PVNCRH neurons in females are particularly affected by a history of alcohol consumption. Interestingly, women have indicated an increase in heavy alcohol use to cope with stress (Rodriguez et al., 2020), perhaps pointing to a potential underlying mechanism in alcohol-mediated changes to PVNCRH neurons that alter stress response.SIGNIFICANCE STATEMENT Paraventricular nucleus of the hypothalamus neurons that release corticotropin releasing hormone (PVNCRH) are vital for stress response. These neurons have been understudied in relation to alcohol and withdrawal despite profound relations between stress, alcohol use disorders (AUD), and relapse. In this study, we use a variety of techniques to show that acute withdrawal from a history of alcohol impacts peripheral stress response, PVNCRH neurons, and behavior. Specifically, PVNCRH are in a hyperactive state during withdrawal, which drives an increase in active stress coping behaviors in female mice only. Understanding how alcohol use and withdrawal affects stress responding PVNCRH neurons may contribute to finding new potential targets for the treatment of alcohol use disorder.

Abstract
BACKGROUND Alcohol-related disorders are a major health problem among Indian male professionals because of the unique nature of socioeconomic and demographic conditions. Various studies have highlighted the association between alcohol-related disorders and hypothalamic-pituitary-adrenal (HPA) axis dysfunction, but the evidence accrued so far is inconclusive. In our study, we have assessed early morning serum total cortisol concentration among Indian adult male population affected with alcohol-related disorder. METHODS A case-based cross-sectional study in which all consecutive patients admitted in the psychiatry ward of a tertiary care hospital with diagnosis of 'alcohol-related disorders', who were meeting all the inclusion criteria, and who had none of the exclusion criteria were part of the study. Diseased controls and healthy controls were chosen by applying strict inclusion and exclusion criteria. Serum early morning (0400 h) total cortisol levels were estimated using automated quantitative enzyme-linked fluorescent assay technique. RESULTS 98 psychiatric patients and 50 healthy controls were evaluated. Out of these 98 patients 66 patients were diagnosed cases of alcohol-related disorder. Morning serum total cortisol levels in patients with alcohol-related disorders was found to be significantly different from healthy controls. CONCLUSION Our study suggests that alcohol-related disorders are associated with chronic changes in HPA axis and significant alteration of early morning serum total cortisol levels were demonstrated in this group of patients.

Abstract
Dysregulation of physiological stress reactivity plays a key role in the development and relapse risk of alcohol dependence. This article reviews studies investigating physiological responses to experimentally induced acute stress in patients with alcohol dependence. A systematic search from electronic databases resulted in 3641 articles found and after screening 62 articles were included in our review. Studies are analyzed based on stress types (i.e., social stress tasks and nonsocial stress tasks) and physiological markers (i.e., the nervous system, the endocrine system, somatic responses and the immune system). In studies applying nonsocial stress tasks, alcohol-dependent patients were reported to show a blunted stress response compared with healthy controls in the majority of studies applying markers of adrenocorticotropic hormone and cortisol. In studies applying social stress tasks, findings are inconsistent, with less than half of the studies reporting altered physiological stress responses in patients. We discuss the impact of duration of abstinence, comorbidities, baseline physiological arousal and intervention on the discrepancy of study findings. Furthermore, we review evidence for an association between blunted physiological stress responses and the relapse risk among patients with alcohol dependence.

Abstract
The endocrine system plays an essential role in communication between various organs of the body to maintain homeostasis. Both substance use disorders (SUDs) and non-substance abuse disrupt this system and lead to hormonal dysregulations. Here, we focus on the comparison between the function of the endocrine system in gambling disorders and alcohol addiction to understand the commonalities and differences in their neurobiological and psychological underpinnings. We review human research to compare findings on gambling addiction and alcohol dependence pertaining to the dynamic interplay between testosterone and cortisol. Understanding and classifying similarities in hormonal responses between behavioural addiction and SUDs may facilitate development of treatments and therapeutic interventions across different types of addictive disorders, while describing differences may shed light on therapeutic interventions for specific disorders. Although research on gambling addiction is in its infancy, such evaluation may still have a positive effect for addiction research, thereby stimulating discovery of "crossover" pharmacotherapies with benefits for both SUDs and nonsubstance addictions.

Alterations in circadian rhythms following alcohol use: A systematic review. Prog Neuropsychopharmacol Biol Psychiatry 2020; 99:109831.

Abstract
Increasing evidence suggest a bidirectional link between disrupted circadian rhythms and alcohol use disorders (AUD). A better understanding of these alcohol-induced changes in circadian rhythms will likely provide important therapeutic solutions. We conducted a systematic review based on the PubMed database examining biological rhythms in all stages of alcohol use: acute alcohol consumption, AUD, alcohol withdrawal, and abstinence. Different changes in circadian rhythms have been observed after a single acute alcohol intake, but also during AUD and alcohol withdrawal. Following a single acute alcohol intake, changes in biological rhythms are dose-dependent, reflected in the melatonin and cortisol secretions, and the core body temperature (CBT) rhythms. These alterations normalize the next morning and appear mostly for acute alcohol intake higher than 0.5 g/kg. These alterations are more severe during AUD and persist over time. In addition, interestingly, opposite patterns of the melatonin physiological ratio between diurnal and nocturnal secretion (N/D ratio < 1) have been observed during AUD and appear to be a marker of chronic daily use. During alcohol withdrawal, circadian rhythms desynchronization correlates with the severity of alcohol withdrawal symptoms and withdrawal complications such as delirium tremens. During abstinence a resynchronization of circadian rhythms of cortisol and CBT appears in most patients about 1 month after alcohol withdrawal. Disruption of melatonin circadian rhythms can persist after 3-12 weeks of abstinence. The circadian genetic vulnerability associated with biological rhythms alterations in alcohol use disorders increases the risk of relapses. Circadian-based interventions could play a critical role in preventing and treating AUD.

Abstract
BACKGROUND AND AIMS People with blunted stress reactivity have poor impulse control and also show increased risk for alcoholism. Exposure to early life adversity (ELA) contributes to blunted reactivity, but individual differences in susceptibility to ELA are not well understood. This study aimed to determine whether exposure to ELA has a greater impact on stress reactivity in young adults with a family history of alcoholism (FH+) compared with young adults with no family history of alcoholism (FH-). DESIGN Observational study using linear modeling. SETTING Oklahoma, USA. PARTICIPANTS Seven hundred and nine young adults (398 females) recruited through community advertisement. MEASUREMENTS We obtained heart rates and cortisol levels in subjects while undergoing public speaking and mental arithmetic stress compared with a resting control day (1418 test sessions). ELA was quantified as 0, 1 or > 1 adverse events experienced by age 15 years. FH+ people had one or two parents with an alcohol use disorder, and FH- controls had no such history for two generations. FINDINGS Increasing levels of ELA predicted progressive blunting of cortisol and heart rate reactivity for the whole sample (Fs = 4.57 and 4.70, Ps ≤ 0.011), but examination by FH status showed that the effect of ELA was significant only among FH+ (Fs ≥ 3.5, Ps < 0.05) and absent in FH- (Ps > 0.40). This difference in ELA impact was not explained by the cortisol diurnal cycle or subjective evaluation of the stressors. CONCLUSIONS People with a family history of alcoholism appear to be vulnerable, in terms of changes to physiological stress response, to the impact of exposure to early life adversity while people with no family history of alcoholism appear to be resilient. Blunted stress reactivity may reflect differential vulnerability to early life adversity in young adults with a family history of alcoholism.

Abstract
Rates of alcohol use disorder (AUD) have increased in women by 84% over the past ten years relative to a 35% increase in men. This substantive increase in female drinking is alarming given that women experience greater alcohol-related health consequences compared to men. Stress is strongly associated with all phases of alcohol addiction, including drinking initiation, maintenance, and relapse for both women and men, but plays an especially critical role for women. The purpose of the present narrative review is to highlight what is known about sex differences in the relationship between stress and drinking. The critical role stress reactivity and negative affect play in initiating and maintaining alcohol use in women is addressed, and the available evidence for sex differences in drinking for negative reinforcement as it relates to brain stress systems is presented. This review discusses the critical structures and neurotransmitters that may underlie sex differences in stress-related alcohol use (e.g., prefrontal cortex, amygdala, norepinephrine, corticotropin releasing factor, and dynorphin), the involvement of sex and stress in alcohol-induced neurodegeneration, and the role of ovarian hormones in stress-related drinking. Finally, the potential avenues for the development of sex-appropriate pharmacological and behavioral treatments for AUD are identified. Overall, women are generally more likely to drink to regulate negative affect and stress reactivity. Sex differences in the onset and maintenance of alcohol use begin to develop during adolescence, coinciding with exposure to early life stress. These factors continue to affect alcohol use into adulthood, when reduced responsivity to stress, increased affect-related psychiatric comorbidities and alcohol-induced neurodegeneration contribute to chronic and problematic alcohol use, particularly for women. However, current research is limited regarding the examination of sex in the initiation and maintenance of alcohol use. Probing brain stress systems and associated brain regions is an important future direction for developing sex-appropriate treatments to address the role of stress in AUD.

Abstract
OBJECTIVE Stress reactivity research has traditionally focused on the idea that exaggerated responses to stress may have adverse effects on health. Accumulating evidence suggests that attenuated responses to stress and delayed recovery may also be problematic. METHODS This review focuses on the role of the stress response of the hypothalamic-pituitary-adrenocortical axis, the endogenous opioid system, and the cardiovascular system in hypertension, pain perception, and addictive behaviors. Results from multiple methods of assessment and stress paradigms conducted in our laboratory over the past two decades are integrated with research from other investigators and with existing theories. RESULTS Research indicates that exaggerated biological and physiological responses to stress and attenuated pain perception are associated with hypertension and risk for cardiovascular diseases. This research complements work linking reduced stress responses with enhanced pain sensitivity and discomfort. Multiple studies have also demonstrated that an attenuated stress response is linked to exacerbation of withdrawal symptoms and relapse in nicotine addiction. Evidence indicates important moderators (i.e., sex, personality traits, and early life adversity) and hypothalamic-pituitary-adrenocortical- and endogenous opioid system-related mechanisms in the altered response to stress. I integrate these findings in a conceptual model emphasizing that robust stress responses in the context of addiction and relapse should be considered as a marker of resiliency. CONCLUSIONS A blunted stress response may indicate long-term physiological dysregulation that could usher harmful consequences for cardiovascular disease, pain perception, and addictive disorders. The impact of dysregulation is influenced by multiple individual and situational factors that should be considered in evaluating the clinical significance of stress response dysregulation.

Abstract
OBJECTIVE Analyze results with respect to cortisol reactivity (CR) in experimental stress paradigms in adults with or without a psychiatric disorder who suffered violence in early developmental stages (infancy or early adolescence); and use these results to propose a clinical tool to determine biological stress indicators. METHODS A systematic review was conducted using several databases and following PRISMA criteria; of a total of 231 articles, 16 satisfied the inclusion criteria and the results were analyzed qualitatively. RESULTS Despite heterogeneity, the results suggested that the people who suffered violence at an early age present a pattern of low CR. In contrast, people who also developed symptoms of post-traumatic stress disorder and depression, regardless of the type of violence, showed increased CR. The majority of studies focused on people who suffered childhood sexual abuse and half of the articles supported the hypothesis that CR is more pronounced in men than in women. CONCLUSIONS The results of this review suggest that cortisol hyperreactivity can be considered a biomarker for treatment and intervention in people with post-traumatic stress disorder and depression who suffered violence at an early age. The results also support evidence that experiencing violence alters stress response and mental health in the long term. However, it is necessary to conduct more studies, in particular studies on hyporeactivity and gender differences.

Abstract
OBJECTIVE To clarify the prevalence of stress, and examine the relationship between sleep disorders and stress coping strategies among highly stressed individuals in the general Japanese population. METHODS A cross-sectional nationwide survey was undertaken in November 2007. Men and women were randomly selected from 300 districts throughout Japan. Data from 7671 (3532 men (average age 53.5 ± 17.0 years) and 4139 women (average age 53.9 ± 17.7 years)) were analyzed. Participants completed a self-reported questionnaire on stress, sleep disorders, and stress coping strategies in the previous month. RESULTS Highly stressed individuals comprised 16.6% (95% confidence interval 15.8-17.5%) of the total sample, and most were aged 20-49 years. In multiple logistic regression, symptoms of insomnia (ie, difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening), excessive daytime sleepiness, nightmares, daytime malfunction, and lack of rest due to sleep deprivation were more prone to occur in highly stressed individuals. In addition, logistic regression analysis controlling for other adjustment factors revealed that stress coping strategies such as 'giving up on problem-solving', 'enduring problems patiently', 'smoking' and 'drinking alcohol' were positively associated with the above-mentioned sleep disorders. On the other hand, stress coping strategies such as 'exercising', 'enjoying hobbies', and 'sharing worries' were inversely associated with the above-mentioned sleep disorders. CONCLUSIONS Distraction-based stress coping (eg, hobbies, exercise, and optimistic thinking) was found to be preferable to problem-based stress coping in a highly stressed Japanese general population.

Abstract
Alcohol is the most commonly used and abused substance worldwide. The emergence of alcohol use disorders, and alcohol dependence in particular, is accompanied by functional changes in brain reward and stress systems, which contribute to escalated alcohol drinking and seeking. Corticotropin-releasing factor (CRF) systems have been critically implied in the transition toward problematic alcohol drinking and alcohol dependence. This review will discuss how dysregulation of CRF function contributes to the vulnerability for escalated alcohol drinking and other consequences of alcohol consumption, based on preclinical evidence. CRF signaling, mostly via CRF1 receptors, seems to be particularly important in conditions of excessive alcohol taking and seeking, including during early and protracted withdrawal, relapse, as well as during withdrawal-induced anxiety and escalated aggression promoted by alcohol. Modulation of CRF1 function seems to exert a less prominent role over low to moderate alcohol intake, or to species-typical behaviors. While CRF mechanisms in the hypothalamic-pituitary-adrenal axis have some contribution to the neurobiology of alcohol abuse and dependence, a pivotal role for extra-hypothalamic CRF pathways, particularly in the extended amygdala, is well characterized. More recent studies further suggest a direct modulation of brain reward function by CRF signaling in the ventral tegmental area, nucleus accumbens, and the prefrontal cortex, among other structures. This review will further discuss a putative role for other components of the CRF system that contribute for the overall balance of CRF function in reward and stress pathways, including CRF2 receptors, CRF-binding protein, and urocortins, a family of CRF-related peptides.

Blunted cardiac stress reactors exhibit relatively high levels of behavioural impulsivity. Physiol Behav 2016; 159:40-4. [PMID: 26988282 DOI: 10.1016/j.physbeh.2016.03.011] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2015] [Revised: 01/26/2016] [Accepted: 03/10/2016] [Indexed: 12/19/2022]
Abstract
Blunted physiological reactions to acute psychological stress are associated with a range of adverse health and behavioural outcomes. This study examined whether extreme stress reactors differ in their behavioural impulsivity. Individuals showing blunted (N=23) and exaggerated (N=23) cardiovascular reactions to stress were selected by screening a healthy student population (N=276). Behavioural impulsivity was measured via inhibitory control and motor impulsivity tasks. Blunted reactors exhibited greater impulsivity than exaggerated reactors on both stop-signal, F(1,41)=4.99, p=0.03, ηp(2)=0.108, and circle drawing, F(1,43)=4.00, p=0.05, η p(2)=0.085, tasks. Individuals showing blunted cardiovascular stress reactions are characterized by greater impulsivity which may contribute to their increased susceptibility to outcomes such as obesity and addiction.

Abstract
BACKGROUND Adolescence represents a period of development during which critical biological, as well as social and cognitive, changes occur that are necessary for the transition into adulthood. A number of researchers have suggested that the pattern of normative brain changes that occurs during this period not only predisposes adolescents to engage in risk behaviours, such as experimentation with drugs, but that they additionally make the adolescent brain more vulnerable to the direct pharmacological impact of substances of abuse. The neural circuits that we examine in this review involve cortico-basal-ganglia/limbic networks implicated in the processing of rewards, emotion regulation, and the control of behaviour, emotion and cognition. FINDINGS AND CONCLUSIONS We identify certain neurocognitive and personality/comorbidity-based risk factors for the onset of substance misuse during adolescence, and summarise the evidence suggesting that these risk factors may be further impacted by the direct effect of drugs on the underlying neural circuits implicated in substance misuse vulnerability.

Abstract
BACKGROUND A growing body of evidence suggests that exercise training may have multiple beneficial effects in individuals with mental health or substance use disorders. Yet, relatively little knowledge exists regarding the benefits of exercise training to augment treatment for alcohol use disorders (AUDs). PURPOSE The purpose of this narrative review is to present a summary of the growing body of published literature supporting exercise training as a treatment strategy for individuals with AUDs. We will provide evidence on the myriad of ways in which exercise may exert a positive effect on AUD outcomes including stress, anxiety, impulsivity, and depression. Further, we will explore how these mechanisms share common neurobiological pathways. The role of exercise in enhancing the social environment and increasing individual self-efficacy to reduce excess and/or inappropriate alcohol consumption will also be discussed. DISCUSSION We will conclude with a description of completed investigations involving exercise training and provide suggestions for next steps in this innovative field of study.

Abstract
BACKGROUND Although the link between psychological distress and altered cortisol level has been already shown; very limited information exists about this association among Black youth. OBJECTIVES We tested sex differences in predictive role of symptoms of anxiety during adolescence on annual decline in morning salivary cortisol levels in early adulthood among Black youth. PATIENTS AND METHODS Data came from wave 1 (year 1994), wave 6 (year 2000), and wave 7 (year 2001) of the Flint adolescent study. In this study 176 Black youth (85 males and 91 females) were followed for 7 years from mean age of 15 at baseline to 22 at the end of follow up. Linear regression was used for data analysis with change in salivary cortisol from 2000 to 2001 as the dependent variable, symptoms of anxiety, at 1994 as independent variable, age, number of employed parents, depressive symptoms and alcohol use at 1994 as controls, and sex as the moderator. RESULTS Higher level of anxiety symptoms at 1994 was predictive of a higher decline in morning salivary cortisol from 2000 to 2001 for all youths, while the effects of baseline socio-economics, depressive symptoms, and alcohol use were controlled. Among female participants, anxiety symptoms at 1994 were predictive of a greater decline in morning salivary cortisol level from 2000 to 2001. The association was not found among males. CONCLUSIONS Our findings suggest sex differences in the predictive role of anxiety symptoms during adolescence on the annual decline in cortisol level during early adulthood. While most research on this topic is among White middle class individuals, our findings shed more light on the longitudinal links between psychological distress and the hypothalamus-pituitary-adrenal (HPA) axis function among Black youth.

Abstract
OBJECTIVE Rurally situated African Americans suffer from stress and drug-related health disparities. Unfortunately, research on potential mechanisms that underlie this public health problem have received limited focus in the scientific literature. This study investigated the effects of perceived stress, alcohol consumption, and genotype on the hypothalamic-pituitary-adrenal (HPA) Axis. METHODS A rural sample of African American emerging adults (n = 84) completed a battery of assessments and provided six samples of salivary cortisol at wakeup, 30 min post wakeup, 90 min post wakeup, 3:00 PM, 3:30 PM, and 4:30 PM. RESULTS Participants with a TT genotype of the CRHR1 (rs4792887) gene tended to produce the most basal cortisol throughout the day while participants with a CC genotype produced the least amount. Increased levels of perceived stress or alcohol consumption were associated with a blunted cortisol awakening response (CAR). Moreover, the CAR was obliterated for participants who reported both higher stress and alcohol consumption. CONCLUSION Perceived stress and alcohol consumption had a deleterious effect on the HPA-Axis. Furthermore, genotype predicted level of cortisol production throughout the day. These findings support the need to further investigate the relationship between stress dysregulation, drug-use vulnerability, and associated health disparities that affect this community.

Abstract
BACKGROUND AND AIMS Problematic Internet use and excessive alcohol consumption have been associated with a host of maladaptive outcomes. Further, low (blunted) cardiovascular and stress hormone (e.g. cortisol) reactions to acute psychological stress are a feature of individuals with a range of adverse health and behavioural characteristics, including dependencies such as tobacco and alcohol addiction. The present study extended this research by examining whether behavioural dependencies, namely problematic Internet use, excessive alcohol consumption, and their comorbidity would also be associated with blunted stress reactivity. METHODS A large sample of university students (N = 2313) were screened using Internet and alcohol dependency questionnaires to select four groups for laboratory testing: comorbid Internet and alcohol dependence (N = 17), Internet dependence (N = 17), alcohol dependence (N = 28), and non-dependent controls (N = 26). Cardiovascular activity and salivary cortisol were measured at rest and in response to a psychological stress protocol comprising of mental arithmetic and public speaking tasks. RESULTS Neither problematic Internet behaviour nor excessive alcohol consumption, either individually or in combination, were associated with blunted cardiovascular or cortisol stress reactions. Discussion It is possible that problematic Internet behaviour and excessive alcohol consumption in a student population were not related to physiological reactivity as they may not reflect ingrained addictions but rather an impulse control disorder and binging tendency. CONCLUSIONS The present results serve to indicate some of the limits of the developing hypothesis that blunted stress reactivity is a peripheral marker of the central motivational dysregulation in the brain underpinning a wide range of health and behavioural problems.

Abstract
AIM This study examined the impact of early lifetime adversity (ELA) on affect regulation and personality in persons with family history (FH+) and without (FH-) a family history of alcoholism. We examined the impact of early life adversity in healthy young adults, 18-30 years of age enrolled in a long-term study on risk for alcohol and other substance abuse. METHODS ELA was assessed by a composite score of low socioeconomic status and personal experience of physical or sexual abuse and/or separation from parents before age 16, resulting in a score of 0, 1-2, or >3 adverse events. Unstable affect regulation and personality variables were obtained via self-report measures. RESULTS Higher ELA scores were seen in FH+ (χ(2)=109.2, p<0.0001) and in women (χ(2)=17.82, p=0.0019). Although higher ELA predicted less emotional stability and more behavioral undercontrol, further analysis including both FH and ELA showed that FH+ persons are prone to poor affect regulation, negative moods, and have risky drinking and drug abuse tendencies independent of ELA level. ELA predicts reduced stress reactivity and poorer cognitive control over impulsive behaviors as shown elsewhere. CONCLUSIONS The present work shows that FH+ have poor mood regulation and antisocial characteristics. The greater prevalence of ELA in FH+ persons indicates that life experience and FH+ work in tandem to result in risky patterns of alcohol and drug experimentation to elevate risk for alcoholism. Further studies of genetic and environmental contributions to alcoholism are called for.

Abstract
OBJECTIVES Khat (Catha edulis), an amphetamine-like plant, is widely used in East Africa and the Arabian Peninsula and is becoming a growing problem in other parts of the world. The concurrent use of tobacco and khat is highly prevalent and represents a public health challenge. We examined for the first time associations of the concurrent use of tobacco and khat with psychophysiological responses to acute stress in two sites in Yemen. METHODS Participants (N = 308; 135 women) included three groups: users of khat and tobacco, users of khat alone, and a control group (nonsmokers/nonusers of khat). These individuals completed a laboratory session in which blood pressures (BP), heart rate, and mood measures were assessed during rest and in response to acute stress. RESULTS Concurrent use of khat and tobacco was associated with attenuated systolic BP, diastolic BP, and heart rate responses to laboratory stress (ps < 0.05) and with increased negative affect relative to the control group (ps < 0.05). CONCLUSIONS Results demonstrated blunted cardiovascular responses to stress and enhanced negative affect in concurrent khat and tobacco users. These findings extend previous studies with other substances and suggest that adverse effects of khat use may lie in its association with the use of tobacco.

Abstract
We examined whether social drinkers whose drinking behavior poses a risk for harmful consequences exhibit altered psychobiological responses to stress following moderate alcohol intake. At risk (n=17) and low risk drinkers (n=27), as identified by the Alcohol Use Disorders Identification Test, completed two laboratory stress sessions, one in which they consumed a drink with alcohol and one without alcohol. Subjective and physiological measures were obtained throughout the study. Reported stimulation following alcohol consumption and sedation post-stress on alcohol day were greater than the no alcohol day in at risk drinkers (ps<.05). Low risk drinkers exhibited stress dampening effects on cortisol levels (p<.05). This was not the case among the high risk drinkers. These results indicate that acute alcohol intake may be associated with enhanced subjective and altered hormonal responses to stress in individuals who are at risk for becoming problem drinkers.

Abstract
Altered reactivity to stress, either in the direction of exaggerated reactivity or diminished reactivity, may signal a dysregulation of systems intended to maintain homeostasis and a state of good health. Evidence has accumulated that diminished reactivity to psychosocial stress may signal poor health outcomes. One source of diminished cortisol and autonomic reactivity is the experience of adverse rearing during childhood and adolescence. The Oklahoma Family Health Patterns Project has examined a cohort of 426 healthy young adults with and without a family history of alcoholism. Regardless of family history, persons who had experienced high degrees of adversity prior to age 16 had a constellation of changes including reduced cortisol and heart rate reactivity, diminished cognitive capacity, and unstable regulation of affect, leading to behavioral impulsivity and antisocial tendencies. We present a model whereby this constellation of physiological, cognitive, and affective tendencies is consistent with altered central dopaminergic activity leading to changes in brain function that may foster impulsive and risky behaviors. These in turn may promote greater use of alcohol other drugs along with adopting poor health behaviors. This model provides a pathway from early life adversity to low stress reactivity that forms a basis for risky behaviors and poor health outcomes.

Abstract
Stress has long been suggested to be an important correlate of uncontrolled drinking and relapse. An important hormonal response system to stress-the hypothalamic-pituitary-adrenal (HPA) axis-may be involved in this process, particularly stress hormones known as glucocorticoids and primarily cortisol. The actions of this hormone system normally are tightly regulated to ensure that the body can respond quickly to stressful events and return to a normal state just as rapidly. The main determinants of HPA axis activity are genetic background, early-life environment, and current life stress. Alterations in HPA axis regulation are associated with problematic alcohol use and dependence; however, the nature of this dysregulation appears to vary with respect to stage of alcohol dependence. Much of this research has focused specifically on the role of cortisol in the risk for, development of, and relapse to chronic alcohol use. These studies found that cortisol can interact with the brain's reward system, which may contribute to alcohol's reinforcing effects. Cortisol also can influence a person's cognitive processes, promoting habit-based learning, which may contribute to habit formation and risk of relapse. Finally, cortisol levels during abstinence may be useful clinical indicators of relapse vulnerability in alcohol-dependent people.

Abstract
RATIONALE Alcohol dependence is associated with high rates of recidivism. Stress has been shown to increase alcohol craving in alcohol-dependent individuals, but the association between stress-induced craving and alcoholism treatment outcome is not well understood. OBJECTIVE The aim of the present study was to examine the relationship between strength of stress-induced alcohol craving in the human laboratory and subsequent drinking in a cohort of treatment-seeking, alcohol-dependent adults. MATERIALS AND METHODS This is a prospective study assessing stress-induced craving in the lab and subsequent treatment outcomes in alcohol-dependent subjects enrolled in a 12-week outpatient study. Stress was induced using a previously developed, individualized, audio recorded stress script and validated with objective (salivary cortisol) and subjective measures of distress. In vivo craving for alcohol was measured pre- and post-challenge using VAS. RESULTS Subjects were 28 (16 male, 12 female) alcohol-dependent outpatients. Greater stress-induced craving was associated with a blunted salivary cortisol response, significantly shorter time to alcohol relapse, higher mean drinks per week, fewer percent days abstinent, and lower rates of complete abstinence over the study duration (all p's < 0.05). Conversely, no demographic or baseline variables were significant predictors of any outcome variable. CONCLUSIONS These results suggest that greater stress-related increases in alcohol craving are associated with poorer alcohol treatment outcomes. The findings support the use of stress-induced craving as a predictor of alcohol relapse propensity. Furthermore, treatments that address high stress levels and the associated high levels of alcohol craving are likely to improve treatment outcomes in alcohol dependence.

Abstract
BACKGROUND Heavy alcohol use as well as alcohol dependence (AD) have been associated with dysregulation of the hypothalamic-pituitary-adrenal (HPA)-axis and the autonomic nervous system (ANS). However, the relative contribution of alcohol use and AD is unclear. METHODS Baseline data were derived from 2947 persons of the Netherlands Study of Depression and Anxiety (NESDA), including non-drinkers (n=498), moderate drinkers (n=2112) and heavy drinkers (n=337). We also distinguished between persons with no lifetime DSM-IV AD (n=2496), remitted AD (> 1 year; n = 243), and current AD (≤ 1 year; n=208). ANS measures included ECG-based heart rate (HR), respiratory sinus arrhythmia (RSA, high RSA reflecting high cardiac parasympathetic control) and pre-ejection period (PEP, high PEP reflecting low cardiac sympathetic control). HPA-axis measures included the cortisol awakening response (area under the curve with respect to the ground [AUCg] and increase [AUCi]), evening cortisol and a 0.5mg dexamethasone suppression test, all measured in saliva. RESULTS Heavy drinkers showed higher basal cortisol levels (AUCg: p=.02; evening cortisol: p=.006) and increased cardiac sympathetic control (higher HR: p=.04; lower PEP: p=.04) compared to moderate drinkers. Persons with current or remitted AD did not differ from persons without lifetime AD on any of the HPA-axis or ANS indicators (all p>.33). Similar patterns of HPA-axis and ANS activity across alcohol use groups were found in persons with and without lifetime AD. CONCLUSIONS Our findings suggest that current heavy alcohol use, rather than current or remitted AD, is associated with hyperactivity of the HPA-axis and increased cardiac sympathetic control.

Abstract
AIMS The effect of transdermal nicotine on stress reactivity was investigated in currently smoking, detoxified, substance-dependent individuals (65% alcohol dependent, n = 51; 31 male) following a psychosocial stressor. METHODS Using a randomized, double-blind, placebo-controlled design, subjects were assigned to receive either active transdermal nicotine (low or high dose) or placebo. Six hours following nicotine administration, subjects performed a laboratory psychosocial stressor consisting of two 4-min public-speaking sessions. RESULTS Consistent with prior reports, substance-dependent individuals displayed a blunted stress response. However, a review of the cortisol distribution data encouraged additional analyses. Notably, a significant minority of the substance-dependent individuals (33%) demonstrated elevated poststress cortisol levels. This group of responders was more likely to be alcohol dependent and to have received the high dose of nicotine [χ2(2) = 32, P < 0.0001], [χ2(2) = 18.66, P < 0.0001]. Differences in salivary cortisol responses between responders and nonresponders could not be accounted for by the length of sobriety, nicotine withdrawal levels, anxiety or depressive symptomatology at the time of the psychosocial stressor. CONCLUSION These results suggest that nicotine administration may support a normalization of the salivary cortisol response following psychosocial stress in subgroups of substance-dependent individuals, particularly those who are alcohol dependent. Given the association between blunted cortisol levels and relapse, and the complex actions of nicotine at central and peripheral sites, these findings support the systematic study of factors including nicotine, which may influence stress reactivity and the recovery process in alcohol-dependent individuals.

Abstract
AIMS We examined within a prospective longitudinal study whether cortisol levels were associated with smoking or drinking behaviours, taking parental substance use into account. DESIGN The influence of parental substance use on cortisol levels of their adolescent offspring at age 10-12 years was examined. Next, cortisol levels of adolescents who initiated smoking or drinking at the first data collection (age 10-12) were compared to non-users. Finally, we examined whether cortisol levels could predict new onset and frequency of smoking and drinking 2 years later. SETTING AND PARTICIPANTS First and second assessment data of the TRacking Adolescents' Individual Lives Survey (TRAILS) were used, including 1768 Dutch adolescents aged 10-12 years, who were followed-up across a period of 2 years. MEASUREMENTS Cortisol was measured in saliva samples at awakening, 30 minutes later, and at 8 p.m. at age 10-12. Self-reported substance use at age 10-12 and 13-14, and parental self-reported substance use were used. FINDINGS Only maternal substance use was related to slightly lower adolescent cortisol levels at 8 p.m. Both maternal and paternal substance use were associated with adolescent smoking and drinking at age 13-14, although fathers' use only predicted the amount used and not the chance of ever use. Finally, higher cortisol levels were related moderately to current smoking and future frequency of smoking, but not to alcohol use. CONCLUSIONS In a general population, parental heavy substance use does not seem to affect cortisol levels consistently in their offspring. We found some evidence for higher, instead of lower, hypothalamic-pituitary-adrenal axis activity as a predictor of smoking in early adolescence.

Abstract
Chronic alcohol abuse is associated with changes in stress and reward pathways that could alter vulnerability to emotional stress and alcohol craving. This study examines whether chronic alcohol abuse is associated with altered stress and alcohol craving responses. Treatment-engaged, 28-day abstinent alcohol-dependent individuals (ADs; 6F/22M), and social drinkers (SDs; 10F/18M) were exposed to a brief guided imagery of a personalized stressful, alcohol-related and neutral-relaxing situation, one imagery condition per session, presented in random order across 3 days. Alcohol craving, anxiety and emotion ratings, behavioral distress responses, heart rate, blood pressure, and salivary cortisol measures were assessed. Alcohol patients showed significantly elevated basal heart rate and salivary cortisol levels. Stress and alcohol cue exposure each produced a significantly enhanced and persistent craving state in alcohol patients that was marked by increased anxiety, negative emotion, systolic blood pressure responses, and, in the case of alcohol cue, behavioral distress responses, as compared to SDs. Blunted stress-induced cortisol responses were observed in the AD compared to the SD group. These data are the first to document that stress and cue exposure induce a persistent negative emotion-related alcohol craving state in abstinent alcoholics accompanied by dysregulated HPA and physiological arousal responses. As laboratory models of stress and negative mood-induced alcohol craving are predictive of relapse outcomes, one implication of the current data is that treatments targeting decreases in stress and alcohol cue-induced craving and regulation of stress responses could be of benefit in improving alcohol relapse outcomes.

Abstract
CONTEXT Evidence for an association between alcohol consumption and activity of the hypothalamic-pituitary-adrenal (HPA) axis is inconclusive. OBJECTIVE Our objective was to assess the relationship between indices of alcohol consumption and salivary cortisol concentration. DESIGN This was a cross-sectional study of alcohol consumption and cortisol secretion from phase 7 (2002-2004) of the Whitehall II study. SETTING An occupational cohort originally recruited in 1985-1987 was included in the study. PARTICIPANTS A total of 2693 men and 977 women had information on cortisol levels and alcohol consumption. OUTCOME MEASURES Saliva samples were taken on waking, waking+0.5, 2.5, 8, and 12 h, and bedtime for the assessment of cortisol. RESULTS In men there was a positive association between cortisol and units of alcohol intake per week (3% increase in cortisol per unit of alcohol consumed; P=0.010). The slope of cortisol decline over the day in heavy drinkers was reduced (heavy drinkers beta=-0.155, moderate drinkers beta=-0.151), indicating reduced control of the HPA axis in heavy drinkers. In women the cortisol awakening response was greater in heavy drinkers 14.15 nmol/liter (9.12-19.17) compared with moderate drinkers 8.69 nmol/liter (7.72-9.67) (P=0.037). CONCLUSIONS This study suggests that alcohol consumption is associated with activation of the HPA axis. These results are not due to alcohol consumption on the day, suggesting chronic changes of the HPA axis in heavy drinking groups.

Abstract
Cortisol is a stress hormone mediated by the hypothalamic-pituitary-adrenal (HPA) axis and a psychobiological marker of genetic risk for alcoholism and other high-risk behavioural characteristics. In previous work with driving under the influence of alcohol (DUI) recidivists, we uncovered a significant inverse relationship between the frequency of past DUI convictions and salivary cortisol, whose strength surpassed those observed between DUI frequency and measures of alcohol abuse and other DUI-related characteristics. This finding emerged using a methodology not specifically contrived to test this relationship. The goals of this follow-up study were to (a) examine if a standardized stress-induction protocol would produce a significant inverse relationship between cortisol response and number of DUI offences; and (b) clarify whether HPA axis dysregulation could be linked to particular DUI-related behavioural correlates, such as alcohol use severity, sensation seeking, and antisocial features. Thirty male DUI recidivists were recruited as well as 11 male non-DUI drivers as a comparison group. Results indicated an inverse relationship between DUI frequency and cortisol response (r(39)=-0.36, p=0.021), as well as a lower cortisol response in DUI offenders than the comparison group (F(1,39)=5.71, p=0.022). Finally, for recidivists, hierarchical regression analyses indicated that experience seeking (R(2)=0.23, p=0.008), followed by number of cigarettes smoked daily ((Delta)R(2)=0.12, p=0.031), combined to explain 35% of the variance in cortisol (F(2,29)=7.26, p=0.003). These findings indicate that severe recidivism may have psychobiological underpinnings, and that HPA axis dysregulation appears to be a mechanism common to high-risk behaviours including DUI recidivism, sensation seeking, and cigarette smoking.

Abstract
Hypothalamo-pituitary-adrenocorticoid (HPA)-axis reactivity to psychosocial or pharmacological stimulants is diminished in alcohol-dependent patients during early abstinence but recovers after several months of abstention. In order to assess the physiological reactivity in the morning we used the cortisol awakening response (CAR) in saliva to compare 24 early abstainers (mean 21.9+/-7.6, range 10-36 days) with 12 alcohol-dependent patients with longer abstention periods (mean 116.8+/-45.7, range 59-230 days) and looked for an association with sleep, especially rapid eye movement (REM) sleep of the preceding night. Both groups did not differ with respect to age, duration of alcohol dependence, daily drinking dosage before detoxification, body mass index, depressivity, level of anxiety, daily cigarette consumption or sleep quality during the preceding 14 days. Sleep in the night before cortisol assessment did not differ with respect to total sleep time (412.4+/-35.9 vs. 407.0+/-38.7 min). Immediately upon awakening and 15, 30, 45 and 60 min later, specimens of salivary cortisol were collected. While starting from equal levels upon awakening longer abstaining patients with alcohol dependence showed a stronger CAR (ANOVA with repeated measurement, time x group effect: F=4.33, p<0.01) with distinctly higher cortisol levels 45 and 60 min after awakening (T=3.79, p<0.001 and T=3.06, p<0.005, respectively). Across both groups the time spent in REM-sleep only correlated with cortisol levels upon awakening (r=0.33, p<0.05). Our data indicate that CAR is a useful tool for investigating alterations in the HPA-axis regulation in abstaining alcohol-dependent patients.

Abstract
BACKGROUND Research has shown that exposure to stress/negative affect and to alcohol cues can each increase alcohol craving and relapse susceptibility in alcohol-dependent individuals. However, whether the emotional and physiological states associated with stress-induced and alcohol cue-induced craving are comparable has not been well studied. Therefore, this study examined the craving, emotional, and physiological responses to stress and to alcohol cues in treatment-engaged, 4-week abstinent, alcohol-dependent individuals using analogous stress and alcohol cue imagery methods. METHOD Twenty treatment-seeking, alcohol-dependent participants (18 males/2 females) were exposed to a brief 5-minute guided imagery procedure that involved imagining a recent personal stressful situation, a personal alcohol cue-related situation, and a neutral-relaxing situation, 1 imagery per session presented in random order. Alcohol craving, anxiety and emotion rating scales, cardiovascular measures, and salivary cortisol were compared across the 3 conditions. RESULTS Exposure to stress and to alcohol cues each produced significant increases in alcohol craving, anxiety, and negative emotions and decreases in positive emotions. Stress-induced alcohol craving was significantly correlated with increases in sadness, anger, and anxiety ratings, but alcohol cue-induced craving was associated with decreases in positive affect (joy and neutral relaxed state) and increases in anxiety and fear ratings. Furthermore, stress increased systolic and diastolic blood pressure responses, but significant increases in salivary cortisol were only observed in the alcohol cue condition. CONCLUSIONS Although both stress and alcohol cues produce increases in anxiety associated with alcohol craving, each produced a dissociable psychobiological state involving subjective emotional, cardiovascular, and cortisol responses. These data could have significant implications for understanding the specific psychobiology associated with stress or alcohol cue exposure and their potential effects on alcohol relapse susceptibility.

Abstract
Adolescence is a high-risk period for development of both depressive and substance use disorders. These two disorders frequently co-occur in adolescents and are associated with significant morbidity and mortality. Given the added economic and psychosocial burden associated with the comorbid condition, identification of risk factors associated with their co-occurrence is of great public health importance. Research with adult animals and humans has indicated several common neurobiological systems that link depressive and addictive disorders. Given the ongoing maturation of these systems throughout adolescence and early adult life, it is not clear how these neurobiological processes influence development and progression of both disorders. A better understanding of the pathophysiological mechanisms leading to the onset and course of these disorders during adolescence will be helpful in developing more effective preventive and treatment strategies, and thereby allow these youth to reach their full potential as adults.

Abstract
BACKGROUND The association between stress and alcohol dependence has been well established. Abnormalities in stress reactivity and hypothalamic-pituitary-adrenal axis (HPA) function may be involved in the mechanistic connection between stress and the initiation, development, and/or maintenance of alcohol dependence. Posttraumatic stress disorder (PTSD) commonly co-occurs with alcohol dependence and is characterized by HPA axis abnormalities. This study investigated the relationship between subjective and neuroendocrine stress reactivity to the cold pressor task (CPT) and prospective alcohol use among individuals with alcohol dependence, with and without comorbid PTSD. METHODS Participants were 63 individuals with (a) alcohol dependence only (n=35) or (b) comorbid alcohol dependence and PTSD (n=28). Participants completed the CPT, a widely used physical laboratory stressor. Subjective stress, craving, adrenocorticotrophin (ACTH), and cortisol were measured before, immediately after, and at 5, 30, 60, and 120 minutes after the CPT. Alcohol use during 1 month following testing was also assessed. RESULTS For the alcohol-only group, change in craving immediately following the CPT and craving during the 120-minute recovery phase were predictive of follow-up alcohol use. For the alcohol/PTSD group, change in craving was not predictive of follow-up use. Baseline drinking was, however, predictive of followup alcohol use for the alcohol/PTSD group. For the alcohol-only group, a blunted ACTH response coupled with a higher change in craving following the CPT was associated with significantly greater frequency and intensity of drinking during the follow-up phase. CONCLUSIONS These preliminary findings demonstrate significant differences between the alcohol-only and the alcohol/PTSD group in predictors of relapse. For the alcohol-only group, reactivity to an acute laboratory stressor may be predictive of subsequent alcohol use. This was not true for the alcohol/PTSD group. Although preliminary, the findings may help shed light on the mechanistic relationship between stress reactivity and increased risk for alcohol relapse and dependence in individuals with and without other Axis I comorbidity.

Abstract
The aim of this study was to assess the reliability of salivary cortisol as a measure of hypothalmic-pituitary-adrenal (HPA) axis function in cocaine dependent individuals. Saliva and total plasma samples were collected from 49 abusers on 3 testing days in the morning, across eight time points per day. Significant associations between saliva and plasma cortisol were observed across all time points collapsed across 3 days in both men and women. These moderately significant correlations suggest that salivary measurements represent a stable, non-invasive and broad indicator of HPA axis functioning in cocaine dependent individuals.

Abstract
The cold pressor test (CPT) and Trier Social Stress Test (TSST) have been shown to reliably increase HPA activity; however, little research has compared responses to these stressors. In this study, biological (plasma cortisol and ACTH levels) and subjective (e.g., stress and mood) responses were compared in 31 subjects administered both the CPT and TSST. Subjects were diagnosed with alcohol dependence and post-traumatic stress disorder (PTSD) (n = 11), alcohol dependence without PTSD (n = 10), PTSD without alcohol use disorder (n = 4), and neither PTSD nor alcohol use disorder (n = 6). All subjects completed both the CPT and TSST. In all groups, the TSST elicited higher levels of ACTH and cortisol than the CPT, and the response time course differed between tasks. The TSST also produced lower mood ratings than the CPT. A comparison of all diagnosed groups with normal controls revealed group differences in ACTH responding for the CPT but not the TSST. The results suggest that the TSST results in a greater HPA response than the CPT; however, the CPT may have utility in diagnostically heterogeneous patients.

Abstract
Hypothalamic pituitary adrenal (HPA) axis and subjective stress response to a cold-water immersion task, the cold pressor task (CPT), in individuals (N=89) with post-traumatic stress disorder (PTSD) were examined. All tests were conducted at 08:00h after an overnight hospital stay. Plasma adrenocorticotrophin hormone (ACTH), cortisol, and subjective stress were examined at baseline and five post-task time points in controls (n=31), subjects with PTSD as a result of an index trauma during childhood (i.e. before age 18; n=25), and subjects with PTSD as a result of an index trauma as an adult (n=33). Approximately, 50% of individuals in both trauma groups were alcohol dependent, and the impact of this comorbidity was also examined. Subjects with PTSD, regardless of age of index trauma, had a less robust ACTH response as compared to controls. Regardless of the presence or absence of comorbid alcohol dependence, subjects with childhood trauma had lower cortisol at baseline and at all post-task measurement points and did not demonstrate the decrease in cortisol over the course of the 2h monitoring period seen in subjects with adult index trauma and controls. The findings reveal differences in the neuroendocrine response to the CPT in individuals with PTSD compared to control subjects, and differences in PTSD subjects when examined by age of index trauma.

Abstract
Abstinent alcoholics show a blunted stress cortisol response that may be a consequence of drinking or a preexisting risk marker. We tested cortisol responses to psychological stress in 186 18-30 year-old, healthy social drinkers having no personal history of alcohol or drug dependence, 91 of whom had one or two alcoholic parents (FH+) and 95 having no family alcoholism for two generations (FH-). We predicted that, similar to alcoholic patients, the FH+ would have reduced stress cortisol responses that would be partially determined by their temperament characteristics, specifically antisocial tendencies as measured by the California Psychological Inventory. On a stress day, subjects performed continuous simulated public speaking and mental arithmetic tasks for 45 min, and on a control day they sat and rested for the same time period. The FH+ who were low in sociability had smaller cortisol responses than FH-, high-sociability persons (t=2.27, p=.02). These two groups were not different in diurnal cortisol secretion patterns or affective responses to the stressors. Persons with a familial risk for alcoholism who have more antisocial tendencies may have altered central nervous system responses to emotionally relevant social challenges. Disrupted cortisol stress responses may serve as a risk marker for the development of substance use disorders.

Abstract
Addiction to alcohol or nicotine involves altered functioning of the brain's motivational systems. Altered functioning of the hypothalamic-pituitary-adrenocortical (HPA) axis may hold clues to the nature of the motivational changes accompanying addiction and vulnerability to addiction. Alcohol and nicotine show at least three forms of interaction with HPA functioning. Acute intake of both substances causes stress-like cortisol responses. Their persistent use may dysregulate the HPA. Finally, the risk for dependence and for relapse after quitting may be associated with deficient cortisol reactivity to a variety of stressors. The HPA is regulated at the hypothalamus by diurnal and metabolic signals, but during acute emotional states, its regulation is superseded by signals from the limbic system and prefrontal cortex. This top-down organization makes the HPA responsive to inputs that reflect motivational processes. The HPA is accordingly a useful system for studying psychophysiological reactivity in persons who may vary in cognitive, emotional, and behavioral tendencies associated with addiction and risk for addiction. Chronic, heavy intake of alcohol and nicotine may cause modifications in these frontal-limbic interactions and may account for HPA response differences in seen in alcoholics and smokers. In addition, preexisting alterations in frontal-limbic interactions with the HPA may reflect addiction-proneness, as shown in studies of offspring of alcohol- and drug-abusing parents. Continuing research on the relationship between HPA function, stress responsivity, and the addictions may yield insights into how the brain's motivational systems support addictions and risk for addictions.

Abstract
Alcoholism and heavy drinking are associated with a number of physiological, behavioral, affective, and cognitive problems. One such problem involves dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, with alcoholics showing higher basal cortisol levels and reduced inhibitory feedback control. In addition, alcohol consumption is associated with decreased heart rate variability (HRV). In the present study we examined the relationships among alcohol consumption, cortisol excretion, and HRV in 542 apparently healthy men. Men in the top tertile of self-reported alcohol consumption had higher cortisol levels and lower HRV compared to men in the lower two tertiles of alcohol consumption. In addition, the inverse relationship between cortisol and HRV was greatly attenuated in the heavy drinking group even after accounting for a number of potential confounding factors. These results support prior research on the HPA axis dysregulation in alcoholics and suggest impaired inhibitory control of the HPA axis in heavy drinkers. The findings are consistent with the neurovisceral integration model, which links central and peripheral processes, and may provide a comprehensive framework for the future investigation of the complex mix of physiological, behavioral, affective, and cognitive factors which comprise the heavy drinking phenotype.

Abstract
BACKGROUND Previous studies have described blunted stress hormone responses after pharmacological activation of the hypothalamic-pituitary-adrenal (HPA) axis in sober alcoholics. The aim of the present study was to compare ACTH, cortisol, and prolactin responses to a psychological stressor in abstinent alcohol-dependent subjects matched to healthy control subjects. METHODS Individuals who met DSM-IV diagnostic criteria for a history of alcohol dependence but not for other axis I disorders were included in the study (n = 18; mean duration of abstinence +/- SEM, 3.5 +/- 5.7 years). Social drinkers (n = 23) served as control subjects. The sober alcohol-dependent and control subjects were matched for demographic measures including levels of stress symptoms. All subjects underwent the Trier Social Stress Test (TSST), a laboratory-based psychological stressor. Prestress and poststress plasma ACTH, cortisol, and prolactin levels, as well as a self-report measure of anxiety (State-Trait Anxiety Inventory), were obtained. RESULTS Nondepressed, abstinent alcoholics and control subjects did not differ with regard to age, racial composition, or baseline or poststress ratings of anxiety. Whereas ACTH and cortisol levels increased in response to the TSST, prolactin levels did not. Stress hormone response curves for the three hormones did not differ between the alcoholics and control subjects. CONCLUSIONS When matched for levels of stress, a laboratory-based psychological stress test did not induce differential hormone response curves for abstinent alcoholics and control subjects.

Abstract
AIMS To examine the relationship between salivary cortisol and frequency of past driving under the influence of alcohol (DUI) convictions. METHODS A total of 104 males with previous DUI convictions (from one to eight) and mean age of 44.7 years were assessed on measures characterizing repeat DUI offenders, including sociodemographic information, alcohol use behaviours, biological indices of the organic consequences of chronic abuse, negative consequences of excessive drinking, past DUI conviction history, impulse control, and antisocial behaviour tendencies. Saliva samples were taken approximately every 30 min over a 6 h period during an exhaustive multidimensional assessment protocol, and were then assayed to obtain cortisol responses. RESULTS Blunted cortisol response, typically observed in alcoholics and in high-risk non-alcoholics, was associated with increased number of past DUI convictions. This association was particularly pronounced in multiple DUI offenders, and was stronger than, and independent of, other measures of alcohol use severity and chronicity commonly used for DUI assessment. CONCLUSIONS Cortisol response may be useful in understanding the mediators underlying repeat DUI offending and the frequent failure of intervention efforts in curbing DUI behaviour.

Abstract
BACKGROUND Individual differences in neural circuitry that regulate emotional reactivity may be associated with alcoholism and antisocial personality disorder (ASPD), a common comorbid condition. The emotion-modulated startle reflex was used to investigate emotional reactivity among alcohol-dependent (AD) men with and without ASPD. METHODS Sixty-two men were tested: (1) AD (n = 24), (2) AD-ASPD (n = 17), and (3) non-AD, non-ASPD controls (n = 21). Participants completed self-report instruments and clinical interviews and had eye-blink electromyograms measured in response to acoustic startle probes while viewing color photographs rated as affectively pleasant, neutral, and unpleasant. RESULTS Startle blink magnitudes were larger during unpleasant as compared with pleasant slides for control and AD groups, resulting in significant linear trend effects (p < 0.001) and nonsignificant quadratic trend effects. In contrast, AD-ASPD did not show a significant difference in blink magnitude during unpleasant and pleasant slides and did not show a significant linear valence trend or quadratic trend effect (p > 0.6). Subjective valence and arousal ratings of the photographs were similar across groups. CONCLUSIONS Adult male alcoholics with ASPD have abnormal emotional responsiveness to both pleasant and unpleasant stimuli relative to alcoholics without ASPD and to controls.

Abstract
We investigated plasma cortisol in a psychological stress paradigm in seven weaned anhedonic alcoholics in comparison with seven age-matched healthy controls. Alcoholics had significantly higher mean plasma cortisol at baseline and no increase following a psychological stress paradigm. Anhedonic alcoholics judged the experimental situation less agreeable than controls. Anhedonic alcoholics may have blunted cortisol response to psychological stress.

Abstract
RATIONALE Environmental stimuli associated with cocaine are known to elicit drug craving and increase the likelihood of relapse. However, the psychobiological changes that occur with exposure to these stimuli and in episodes of drug craving are not well understood. This study examined the response of brain stress circuits to environmental stimuli that are known to increase cocaine craving in cocaine dependent individuals. METHODS Fifty-four treatment seeking cocaine dependent individuals, who were admitted to an inpatient treatment research unit for 2-4 weeks, participated in three laboratory sessions. Subjects were exposed to a brief 5-min guided imagery procedure that involved imagining a recent personal stressful situation, a drug-related situation and a neutral-relaxing situation, one imagery per session presented in random order. Subjective ratings of craving and anxiety, cardiovascular measures, and plasma levels of adrenocorticotrophic hormone (ACTH), cortisol, prolactin, norepinephrine (NE) and epinephrine (EPI) were assessed. RESULTS Exposure to stress and to drug cues each resulted in significant increases in cocaine craving and subjective anxiety, pulse rate, systolic blood pressure, ACTH, cortisol, prolactin and NE as compared to the response to neutral imagery. In addition, stress imagery also increased diastolic blood pressure and plasma EPI as compared to responses to the drug cue imagery and neutral-relaxing imagery. CONCLUSIONS The findings indicate a significant activation of the CRF-HPA axis and noradrenergic/sympatho-adreno-medullary (SAM) system response during stress-induced and drug cue induced cocaine craving states in cocaine dependent individuals. The role of stress system activation in cocaine craving and in cocaine use is discussed.

Abstract
Studies of the hypothalamic-pituitary-adrenal (HPA) axis in persons with posttraumatic stress disorder (PTSD) have produced variable findings. This review focuses on the factors likely to have affected the outcome of these studies, including population characteristics and experimental design. Also discussed is a possible role for the adrenal neurosteroid dehydroepiandrosterone (DHEA) as a mediator of HPA axis adaptation to extreme stress and the psychiatric symptoms associated with PTSD. The antiglucocorticoid properties of DHEA may contribute to an upregulation of HPA axis responses as well as mitigate possible deleterious effects of high cortisol levels on the brain in some PTSD subpopulations. The neuromodulatory effects of DHEA and its metabolite DHEAS at gamma-aminobutyric acid and N-methyl-D-aspartate receptors in the brain may contribute to psychiatric symptoms associated with PTSD. The possible importance of other neurohormone systems in modulating HPA axis and symptom responses to traumatic stress is also discussed. Understanding the complex interactions of these stress-responsive neurosteroid and peptide systems may help explain the variability in patterns of HPA axis adaptation, brain changes, and psychiatric symptoms observed in PTSD and lead to better targeting of preventive and therapeutic interventions.

Abstract
The present study examined relationships among stressful events, personality characteristics, and affective status in males and females of various alcohol drinking patterns. We examined a total of 154 participants from three distinct alcohol subgroups: alcohol dependent, problem drinker, and light social drinker. These subjects did not meet criteria for any concurrent nonalcohol comorbid psychiatric disorder. The study included an alcohol quantity-frequency interview and self-report questionnaires on stressful life events, depressive symptoms, trait anxiety, and personality characteristics. Results showed female alcoholics reported significantly greater depression, anxiety, and neuroticism compared to their male counterparts (and all other drinking groups). Female problem drinkers reported significantly greater depressive symptoms and health-related stressful events compared to male problem drinkers and the light drinkers. In contrast, male problem drinkers did not show elevations on these dimensions and more closely resembled light drinkers, of whom no gender differences were found. The findings support theories suggesting a "telescoping" of complications, health-related stress, and mood dysfunction in women at a lower threshold level of alcohol consumption compared to their male counterparts.
