Jason S Jacobskind, Zachary J Rosinger, Tiffany Gonzalez, Kristen L Zuloaga, Damian G Zuloaga
Sex differences in methamphetamine (MA) abuse and consequences of MA have been reported with females showing an increased addiction phenotype and withdrawal symptoms. One mechanism through which these effects might occur is via sex-specific alterations in the hypothalamic-pituitary-adrenal (HPA) axis and its associated brain regions. In this study, mice were administered MA (5 mg/kg) or saline for 10 consecutive days. During early withdrawal, anxiety-like behaviors were assessed in the open field, light/dark box, and elevated plus maze...

OBJECTIVE: Microbial translocation and monocyte activation predict mortality in treated HIV. We examined whether substance use independently contributes to these pathophysiologic processes. DESIGN: Cross-sectional study at baseline for a randomized controlled trial. METHODS: HIV-positive, methamphetamine-using men who have sex with men (MSM) with undetectable HIV viral load (< 40 copies/mL) were enrolled. We examined if plasma biomarkers of monocyte activation and intestinal barrier integrity were associated with the following: 1) reactive urine toxicology results (Tox+) for stimulants (i...

Sex differences in patterns of methamphetamine (MA) abuse have been reported with females (humans and rodents) showing an elevated addiction phenotype. Previous findings indicate MA-induced hypothalamic-pituitary-adrenal (HPA) axis activation is also sexually dimorphic with females exhibiting an elevated glucocorticoid release and differential neural activation patterns within HPA axis-associated brain regions. These effects may contribute to sex differences in abuse. To determine the role of gonadal hormones in mediating sex differences in MA-induced glucocorticoids, male and female C57BL/6J mice were gonadectomized or sham-operated, and following recovery, injected with MA (5mg/kg) and sacrificed 60min or 120min later...

Few studies have examined the association between methamphetamine (MA) abuse and sexually transmitted infection (STI) risk among heterosexual male MA users in China. A total of 288 heterosexual male MA users who met our inclusion criteria were recruited from nightclubs, KTVs, bars, bath centres and an STI clinic. STIs were screened among the participants, and the risk factors related to STIs were analysed by multivariate logistic regression in SPSS 11.0. Among the 288 heterosexual male MA users, 51 (17.7%) had syphilis, 36 (12...

BACKGROUND: Evidence indicates that oxytocin, an endogenous peptide well known for its role in social behaviors, childbirth, and lactation, is a promising addiction pharmacotherapy. We employed a within-session behavioral-economic (BE) procedure in rats to examine oxytocin as a pharmacotherapy for methamphetamine (meth) addiction. The BE paradigm was modeled after BE procedures used to assess motivation for drugs in humans with addiction. The same BE variables assessed across species have been shown to predict later relapse behavior...

OBJECTIVES: Patients with schizophrenia often suffer comorbid substance abuse regardless of gender. However, the vast majority of studies are only conducted in male subjects. Therefore, the aim of these experiments is to assess addictive behaviors of both sexes in a neurodevelopmental model of schizophrenia induced by prenatal methylazoxymethanol (MAM) acetate exposure. METHODS: MAM (22 mg/kg) was administered intraperitoneally on gestational day 17. Two studies were performed in the offspring: (1) an alcohol-drinking procedure to assess daily intake of 20% alcohol and relapse-like behavior after a period of forced abstinence; (2) Methamphetamine (METH) intravenous self administration (IVSA) followed by forced abstinence and reinstatement phases...

Methamphetamine (METH) has become one of the most widely abused drugs in South Florida, particularly among MSM who may or may not be HIV seropositive. High rates of childhood trauma have been reported among HIV-infected MSM (Chartier et al., 2010), but, the association of childhood trauma, and mood disorders with methamphetamine use in HIV-infected men, has not been comprehensively explored. A better understanding of the association between these factors could improve existing substance abuse treatment intervention strategies and medical treatment programs (e...

OBJECTIVES: Methamphetamine (MA) addiction has no known effective pharmacotherapy. Small trials showed beneficial effects for oral naltrexone in amphetamine users. Trials in alcohol-dependent subjects showed better response in persons with the A118G single nucleotide polymorphism of the μ-opioid receptor. We conducted a pharmacogenetic trial of sustained release intramuscular naltrexone to examine the role of the A118G single nucleotide polymorphism in MA dependence. METHOD: All eligible A118G subjects screened were enrolled; an equal number of wild type (A118A) subjects were selected using modified urn randomization, balanced on sex and frequency of recent MA use...

Considerable insight has been gained into the comorbid, interactive effects of HIV and drug abuse in the brain using experimental models. This review, which considers opiates, methamphetamine, and cocaine, emphasizes the importance of host genetics and glial plasticity in driving the pathogenic neuron remodeling underlying neuro-acquired immunodeficiency syndrome and drug abuse comorbidity. Clinical findings are less concordant than experimental work, and the response of individuals to HIV and to drug abuse can vary tremendously...

Nicotine produces core symptoms of substance dependence (craving and withdrawal) without any psychotic symptoms. The psychopharmacological structure of craving is hypothesized to be constituted by three components: the primary reinforcing property of a substance, the secondary reinforcing property of that substance (conditioned aspects of the environment, such as contextual or specific cues associated with substance taking), and the negative affective motivational property during withdrawal (i.e. the desire to avoid the dysphoric withdrawal symptoms elicits craving)...
