Methylation of genes and regulation of inflammatory processes on emotional response in young adults with alcoholic parents. Brain Behav Immun Health 2022; 25:100505. [PMID: 36110145 PMCID: PMC9468507 DOI: 10.1016/j.bbih.2022.100505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 08/19/2022] [Accepted: 08/23/2022] [Indexed: 10/31/2022] Open
Abstract
Many Americans are adult children of an alcoholic parent (ACoA), which can confer an increased risk of trauma and hazardous alcohol use, as well as heritable and environmental genetic influence. Psychological health and related neural activity can be influenced by inflammation responses, but it is not clear how these factors interact regarding risk or resilience to hazardous alcohol use. The goals of this study were to better understand the relationships between current alcohol use and inflammation, how these are modified by single nucleotide polymorphisms (SNPs) and/or epigenetic modifications of inflammation-associated genes; and how these alter neural reactivity to emotionally-salient stimuli. To do so, ACoA participants were dichotomized as resilient (not engaged in hazardous alcohol use) or vulnerable (currently engaged in hazardous alcohol use). Measures of blood-oxygen-level-dependent (BOLD) activity within regions of interest (ROIs), SNPs and DNA methylation of specific inflammation regulatory genes, and biological markers of inflammation were compared between these groups. Vulnerable ACoAs exhibited higher plasma C-reactive protein (CRP) and greater BOLD activity in the right hippocampus and ventral anterior cingulate cortex in response to emotional cues as well as reduced methylation of CRP and glucocorticoid-related genes. Path analysis revealed significant relationships between alcohol use, SNPs, DNA methylation of inflammatory-related genes, CRP levels, and BOLD activity to emotional stimuli. Taken together, these findings suggest a complex association related to hazardous alcohol use in ACoAs that may predict current inflammation and neural reactivity to emotional stimuli. A better understanding of these associations could direct the future of individual treatment options.

Neural and psychological characteristics of college students with alcoholic parents differ depending on current alcohol use. Prog Neuropsychopharmacol Biol Psychiatry 2018; 81:284-296. [PMID: 28939188 PMCID: PMC5690848 DOI: 10.1016/j.pnpbp.2017.09.010] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Revised: 09/11/2017] [Accepted: 09/15/2017] [Indexed: 12/16/2022]
Abstract
A significant proportion of college students are adult children of an alcoholic parent (ACoA), which can confer greater risk of depression, poor self-esteem, alcohol and drug problems, and greater levels of college attrition. However, some ACoA are resilient to these negative outcomes. The goal of this study was to better understand the psychobiological factors that distinguish resilient and vulnerable college-aged ACoAs. To do so, scholastic performance and psychological health were measured in ACoA college students not engaged in hazardous alcohol use (resilient) and those currently engaged in hazardous alcohol use (vulnerable). Neural activity (as measured by functional magnetic resonance imaging) in response to performing working memory and emotion-based tasks were assessed. Furthermore, the frequency of polymorphisms in candidate genes associated with substance use, risk taking and stress reactivity were compared between the two ACoA groups. College ACoAs currently engaged in hazardous alcohol use reported more anxiety, depression and posttraumatic stress symptoms, and increased risky nicotine and marijuana use as compared to ACoAs resistant to problem alcohol use. ACoA college students with current problem alcohol showed greater activity of the middle frontal gyrus and reduced activation of the posterior cingulate in response to visual working memory and emotional processing tasks, which may relate to increased anxiety and problem alcohol and drug behaviors. Furthermore, polymorphisms of cholinergic receptor and the serotonin transporter genes also appear to contribute a role in problem alcohol use in ACoAs. Overall, findings point to several important psychobiological variables that distinguish ACoAs based on their current alcohol use that may be used in the future for early intervention.

Abstract
Alcohol abuse often co-exists with a major depressive disorder. In order to understand the development of this comorbidity, it is important to concentrate on the preceding process. It has been suggested that the link between alcohol use and depressive symptoms is a result of an interaction with genetic factors. The aim of this study was to longitudinally examine the effect of the 5-HTTLPR genotype on the association between depressive symptoms and alcohol use in a Dutch community sample. Following a stepwise approach, bivariate correlations, longitudinal regression analyses, and latent growth curve analyses were separately conducted for 316 males and 321 females. A positive correlation between depressive symptoms and alcohol use was shown in female carriers of the 5-HTTLPR short allele. In addition, latent growth curve analyses showed a positive association between alcohol use and the intercept of depressive symptoms (but not the slope), but only in female carriers of the 5-HTTLPR short allele. These findings show that alcohol use may be positively related, at least cross-sectionally, to depressive symptoms in female carriers of the 5-HTTLPR S allele, and indicate that moderators such as SLC6A4 genotype and sex need to be taken into account when examining associations between depressive symptoms and drinking behavior. In order to gain insight into the longitudinal association between alcohol use and depressive symptoms, studies should concentrate on earlier stages and focus on more fine-grained research designs that allow day-to-day changes in both alcohol use and depressive symptoms.

Abstract
There is evidence of the reciprocal influence between the alteration of circadian rhythms and Substance Use Disorders (SUD), and part of the success of the SUD treatment lays in the patient's rhythmic recovery. We aim to elucidate the effect of the SUD treatment in circadian rhythmicity considering, for the first time, the age of onset of substance use (OSU) and duration of abstinence. We registered the sleep-wake schedules, the chronotype and the distal skin temperature of 114 SUD patients with at least 3 months of abstinence, considering whether they had begun consumption at age 16 or earlier (OSU ≤ 16, n = 56) or at 17 or later (OSU ≥ 17, n = 58), and duration of abstinence as short (SA: 3 to 5 months, n = 38), medium (MA: 6 to 9 months, n = 35) or long (LA: more than 9 months, n = 41). Moreover, we compared the patients' distal skin temperature pattern with a similar sample of healthy controls (HC, n = 103). SUD patients showed a morningness tendency and higher night values, amplitude and stability, a better adjustment to the cosine model and lower minimum temperature and circadianity index in the distal skin temperature rhythm, in contrast to the HC group. The OSU ≥ 17 and LA groups showed a more robust distal skin temperature pattern, as well as milder clinical characteristics when compared to the OSU ≤ 16 and SA groups, respectively. The circadian disturbances associated to substance consumption seem to improve with treatment, although the age of OSU and the duration of abstinence are modulating variables. Our results highlight the need to include chronobiological strategies that boost circadian rhythmicity both in SUD prevention and rehabilitation programs. The measurement of distal skin temperature rhythm, a simple and reliable procedure, could be considered an indicator of response to treatment in SUD patients.

Abstract
BACKGROUND The age of onset of substance use (OSU) as well as the coping strategies (CS) influence both the development and the course of Substance Use Disorders (SUD). We aim to examine the differences in the CS applied to deal with treatment in men with SUD, considering whether the age of OSU had begun at age 16 or earlier (OSU ≤ 16) or at 17 years or later (OSU ≥ 17), as well as the associations of the CS with clinical variables were studied. METHODS A total of 122 patients with at least three months of abstinence, 60 with OSU≤16 and 62 with OSU≥17, were evaluated through the Coping Strategies Inventory and clinical assessment tools. RESULTS The OSU≤16 patients were younger and presented a worse clinical state. Compared to the norms, the SUD patients were less likely to use adaptive CS, although this was more remarkable for the OSU≤16 group. Furthermore, the OSU≤16 patients presented a CS pattern of higher Disengagement, with lesser use of Social Support and higher Problem Avoidance and Social Withdrawal. In the whole SUD sample, the severity of addiction, number of relapses and age of OSU (as a continuous variable) were related to maladaptive coping. Nevertheless, the cut-off age of OSU modulated these results. CONCLUSIONS The OSU≤16 was a risk factor for presenting greater clinical severity and a more dysfunctional CS profile to deal with treatment. Thus, the cut-off age considered has allowed us to differentiate SUD patients with more vulnerability to present worse clinical prognosis who may require specific prevention and rehabilitation strategies discussed throughout this work.

Abstract
Parental alcohol use disorders (AUDs) have been conceptualized as a chronic stressor that can lead to deleterious long-term outcomes in children of individuals with AUDs. Yet, while many individuals are detrimentally affected by their parents' problematic alcohol use, and go on to manifest psychological problems, others do not. How individuals cope with the stress of having a parent with an AUD is believed to be an important moderator of this differential outcome. This study assessed whether individuals' alcohol-specific coping styles predicted alcohol use, positive or negative life events, and depression, using a sample of 465 college students, of whom 20% were adult children of individuals with alcohol use disorders, colloquially known as adult children of alcoholics (ACOAs), and a battery of well-validated, self-report measures. Participant ACOAs reported less 'engaged' and 'total' alcohol-specific coping strategies and more 'withdrawal' alcohol-specific coping strategies than their non adult children of alcoholics (NACOAs) counterparts. Across participants, women reported more 'engaged', 'tolerant/inactive', and 'total' coping than men. Although ACOAs reported significantly more negative life events, which predicted more passive coping styles, they did not differ significantly from NACOAs on measures of problematic alcohol use or depression, supporting theories of resilience in ACOAs regardless of their alcohol-specific coping styles. For NACOAs, 'tolerant' coping predicted greater depression and alcohol-related problems; 'engaged' coping predicted fewer alcohol problems. Results suggest that ACOAs cope differently with problematic alcohol use among relatives and friends compared with NACOAs and are more likely to experience negative life events. Additionally, alcohol-related coping strategies have more predictive utility in NACOAs than ACOAs.
