Chang HM, Chen C, Lu ML, Jou S, Santos VHJ, Goh KK. The interplay of childhood trauma, oxytocin, and impulsivity in predicting the onset of methamphetamine use. CHILD ABUSE & NEGLECT 2024; 147:106579. [PMID: 38048654 DOI: 10.1016/j.chiabu.2023.106579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 11/19/2023] [Accepted: 11/23/2023] [Indexed: 12/06/2023]
Abstract
BACKGROUND Childhood trauma is associated with substance use disorders, including methamphetamine use disorder (MUD). Oxytocin, involved in social bonding, stress regulation, and reward processing, may influence addiction vulnerability and impulsivity in individuals with a history of childhood trauma. OBJECTIVE To investigate the relationships among childhood trauma, oxytocin levels, impulsivity, and the age of first methamphetamine use in individuals with MUD. PARTICIPANTS AND SETTING The study included 298 male participants (148 individuals with MUD and 150 healthy controls) from both probation offices and psychiatric clinics. METHODS Childhood trauma was assessed using the Childhood Trauma Questionnaire-Short Form (CTQ-SF), impulsivity with the Barratt Impulsiveness Scale-11 (BIS-11), and plasma oxytocin levels were obtained. RESULTS Individuals with MUD exhibited higher levels of childhood trauma, impulsivity, and lower plasma oxytocin levels compared to healthy controls. Childhood trauma was associated with a younger age of first methamphetamine use, higher impulsivity, and lower oxytocin levels among individuals with MUD. Plasma oxytocin levels partially mediated the relationship between childhood trauma and both the age of first methamphetamine use and impulsivity. Serial mediation analysis demonstrated that oxytocin levels and impulsivity sequentially mediated the relationship between childhood trauma and the age of first methamphetamine use. CONCLUSIONS The findings reveal the complex interplay among childhood trauma, oxytocin, impulsivity, and methamphetamine use, emphasizing the importance of considering these factors in prevention and intervention strategies for MUD. Future research should explore oxytocin and impulsivity-focused interventions to mitigate the effects of childhood trauma and reduce MUD development risk.

COPE and oxytocin for the treatment of co-occurring PTSD and alcohol use disorder: Design and methodology of a randomized controlled trial in U.S. military veterans. Contemp Clin Trials 2023; 126:107084. [PMID: 36646315 PMCID: PMC9998357 DOI: 10.1016/j.cct.2023.107084] [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: 11/17/2022] [Revised: 01/06/2023] [Accepted: 01/11/2023] [Indexed: 01/15/2023]
Abstract
BACKGROUND A significant proportion of individuals with alcohol use disorder (AUD) also meet criteria for posttraumatic stress disorder (PTSD). Military veterans are at increased risk for developing co-occurring AUD/PTSD, with prevalence rates 2-4 times higher than the general population. Research is needed to develop more effective treatments for this common comorbidity. The current investigation addresses this need by examining the synergistic effects of a novel pharmacotherapy combined with psychotherapy for co-occurring AUD/PTSD among veterans. Accumulating evidence suggests that the neuropeptide oxytocin (OT) is a promising pharmacotherapy to augment psychotherapy for AUD/PTSD. OT targets neurobiological and behavioral dysregulation common to both AUD and PTSD, in particular, corticolimbic connectivity. Human and animal studies show OT reduces alcohol self-administration, tolerance, and withdrawal; enhances fear extinction; and promotes prosocial behaviors. The current study builds on previous work by examining OT among veterans with AUD/PTSD receiving Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure (COPE), an evidence-based integrated treatment. METHODS This paper describes the rationale, design, and methodology of a Stage II, 12-week, double-blind, randomized clinical trial of intranasal OT (40 IU) versus placebo combined with COPE among veterans (N = 180) with current AUD/PTSD. In addition, the effects of treatment on corticolimbic connectivity will be examined using functional magnetic resonance imaging (fMRI) at pre- and post-treatment. CONCLUSIONS The proposed study will provide new knowledge and mechanistic insights to accelerate research in this understudied area and may lead to improved treatment outcomes for co-occurring AUD/PTSD.
